PART I

Item 1.    Business

Our Company

        Unless the context otherwise indicates or requires, as used in this Annual Report, references to "we," "us," "our," or the "Company" refer to Spirit AeroSystems Holdings, Inc., its subsidiaries and predecessors. References to "Spirit" refer only to our subsidiary, Spirit AeroSystems, Inc., and references to "Spirit Holdings" or "Holdings" refer only to Spirit AeroSystems Holdings, Inc. References to "Boeing" refer to The Boeing Company and references to "Airbus" refer to Airbus S.A.S., a division of European Aeronautic Defense & Space NV.

        We are one of the largest independent non-OEM (original equipment manufacturer) aircraft parts designers and manufacturers of commercial aerostructures in the world, based on annual revenues, as well as the largest independent supplier of aerostructures to Boeing. In addition, we are one of the largest independent suppliers of aerostructures to Airbus. Boeing and Airbus are the two largest aircraft OEMs in the world. Aerostructures are structural components such as fuselages, propulsion systems and wing systems for commercial and military aircraft. For the twelve months ended December 31, 2011, we generated net revenues of $4,863.8 million, and had net income of $192.4 million.

        Spirit AeroSystems Holdings, Inc. ("Holdings" or the "Company") was incorporated in the state of Delaware on February 7, 2005, and commenced operations on June 17, 2005 through the acquisition of Boeing's operations in Wichita, Kansas; Tulsa, Oklahoma and McAlester, Oklahoma (the "Boeing Acquisition") by an investor group led by Onex Partners LP and Onex Corporation (together with its affiliates, "Onex"). Boeing's commercial aerostructures manufacturing operations in Wichita, Kansas and Tulsa and McAlester, Oklahoma, are referred to in this Report as "Boeing Wichita." Although Spirit began operations as a stand-alone company in 2005, its predecessor, Boeing Wichita (the "Predecessor"), had 75 years of operating history and expertise in the commercial and military aerostructures industry. Spirit Holdings, Spirit's parent company, has had publicly traded shares on the New York Stock Exchange under the ticker "SPR" since November 2006. Onex continues to hold approximately 92% of Spirit Holdings' class B common shares, which represents approximately 62% of total Spirit Holdings stockholder voting power.

        On April 1, 2006, we became a supplier to Airbus through our acquisition of the aerostructures division of BAE Systems (Operations) Limited, referred to in this Report as "BAE Systems." The acquired division of BAE Systems is referred to in this Report as "BAE Aerostructures," and the acquisition of BAE Aerostructures is referred to as the "BAE Acquisition."

        We manufacture aerostructures for every Boeing commercial aircraft currently in production, including the majority of the airframe content for the Boeing B737, the most popular major commercial aircraft in history. As a result of our unique capabilities both in process design and composite materials, we were awarded a contract that makes us the largest aerostructures content supplier on the Boeing B787, Boeing's next generation twin aisle aircraft. In addition, we are one of the largest content suppliers of wing systems for the Airbus A320 family, we are a significant supplier for the Airbus A380, and we will be a significant supplier for the new Airbus A350 XWB (Xtra Wide-Body) after the development stage of the program. Sales related to the large commercial aircraft market, some of which may be used in military applications, represented approximately 99% of our net revenues for the twelve-month period ended December 31, 2011.

        We derive our revenues primarily through long-term supply agreements with Boeing and Airbus. For the twelve months ended December 31, 2011, approximately 85% and 10% of our net revenues were generated from sales to Boeing and Airbus, respectively. We are currently the sole-source supplier of 97% of the products we sell to Boeing and Airbus, as measured by the dollar value of products sold. We are a critical partner to our customers due to the broad range of products we currently supply to them and our leading design and manufacturing capabilities using both metallic and composite materials. Under our supply agreements with Boeing and Airbus, we supply products for the life of the aircraft program (other

than the A350 XWB and A380), including commercial derivative models. For the A350 XWB and A380, we have long-term requirements contracts with Airbus that cover a fixed number of product units at established prices.

        Since Spirit's incorporation, the Company has expanded its customer base to include Sikorsky, Rolls-Royce, Gulfstream, Bombardier, Mitsubishi Aircraft Corporation, Southwest Airlines, Continental Airlines and American Airlines. The Company has its headquarters in Wichita, Kansas, with manufacturing facilities in Tulsa and McAlester, Oklahoma; Prestwick, Scotland; Wichita, Kansas; Kinston, North Carolina; and Subang, Malaysia. The Company also recently constructed an assembly plant for the A350 XWB aircraft in Saint-Nazaire, France, which began its operations during 2011.

Our History

        In December 2004 and February 2005, an investor group led by Onex formed Spirit and Spirit Holdings, respectively, for the purpose of acquiring Boeing Wichita. The Boeing Acquisition was completed on June 16, 2005. Prior to the acquisition, Boeing Wichita functioned as an internal supplier of parts and assemblies for Boeing's airplane programs and had very few sales to third parties.

        In connection with the Boeing Acquisition, we entered into a long-term supply agreement under which we are Boeing's exclusive supplier for substantially all of the products and services provided by Boeing Wichita to Boeing prior to the Boeing Acquisition. The supply agreement is a requirements contract covering certain products such as fuselages, struts/pylons and wing components for Boeing B737, B747, B767 and B777 commercial aircraft programs for the life of these programs, including any commercial derivative models. Pricing for existing products on in-production models is contractually set through May 2013, with average prices decreasing at higher volume levels and increasing at lower volume levels. We also entered into a long-term supply agreement for Boeing's new B787 aircraft covering the life of this aircraft program, including commercial derivatives. Under this contract we are Boeing's exclusive supplier for the forward fuselage, fixed and moveable leading wing edges and engine pylons for the B787. Pricing for the initial configuration of the B787-8 model is generally set through 2021, with prices decreasing as cumulative production volume levels are achieved. Prices are subject to adjustment for abnormal inflation (above a specified level in any year) and for certain production, schedule and other specific changes, including design changes from the contract configuration baseline. We have negotiated with Boeing an amendment to the B787 Supply Agreement on statement of work and pricing for changes relating to future commercial derivatives, such as the B787-9.

        On April 1, 2006, through our wholly-owned subsidiary, Spirit Europe, we acquired BAE Aerostructures. Spirit Europe manufactures leading and trailing wing edges and other wing components for commercial aircraft programs for Airbus and Boeing. The BAE Acquisition provides us with a foundation to increase future sales to Airbus, as Spirit Europe is a key supplier of wing and flight control surfaces for the A320 platform, Airbus' core single-aisle program, and of wing components for the A380 platform, one of Airbus' most important new programs and the world's largest commercial passenger aircraft. In July 2008, Spirit Europe was awarded a contract with Airbus to design and assemble a major wing structure for the A350 XWB program. Under our supply agreements with Airbus, we supply most of our products for the life of the aircraft program (other than the A350 XWB and A380), including commercial derivative models, with pricing determined through 2015. For the A380 and A350 XWB, we have long-term requirements contracts with Airbus that cover a fixed number of units.

        In November 2006, we issued and sold 10,416,667 shares of our class A common stock and certain selling stockholders sold 52,929,167 shares of our class A common stock at a price to the public of $26.00 per share in our initial public offering. In May 2007, certain selling stockholders sold 34,340,484 shares of our class A common stock at a price to the public of $33.50 per share in a secondary offering of our class A common stock. In April 2011, certain selling stockholders sold 10,307,375 shares of our class A common stock at a price to the underwriters of $24.49 per share in a secondary offering of our class A common stock.

Our Relationship with Boeing

Supply Agreement with Boeing for B737, B747, B767 and B777 Platforms

        Overview.    In connection with the Boeing Acquisition, Spirit entered into long-term supply agreements under which we are Boeing's exclusive supplier for substantially all of the products and services provided by Boeing Wichita to Boeing prior to the closing of the Boeing Acquisition. The main supply contract is primarily comprised of two separate agreements: (1) the Special Business Provisions, or Sustaining SBP, which sets forth the specific terms of the supply arrangement with regard to Boeing's B737, B747, B767 and B777 aircraft and (2) the General Terms Agreement, or GTA, which sets forth other general contractual provisions relating to our various supply arrangements with Boeing, including provisions relating to termination, events of default, assignment, ordering procedures, inspections and quality controls. The summary below describes provisions contained in both the Sustaining SBP and the GTA as both agreements govern the main supply arrangement. We refer to the Sustaining SBP, the GTA and any related purchase order or contract collectively as the "Supply Agreement." The Supply Agreement is a requirements contract which covers certain products, including fuselages, struts/pylons and nacelles (including thrust reversers), wings and wing components, as well as tooling, for Boeing B737, B747, B767 and B777 commercial aircraft programs for the life of these programs, including any commercial derivative models. During the term of the Supply Agreement and absent default by Spirit, Boeing is obligated to purchase from Spirit all of its requirements for products covered by the Supply Agreement and is prohibited from manufacturing such products itself. Although Boeing is not required to maintain a minimum production rate, Boeing is subject to a maximum production rate above which it must negotiate with us regarding responsibility for non-recurring expenditures related to a capacity increase.

        Pricing.    The Supply Agreement sets forth established prices for recurring products through May 2013. Prices are adjusted each year based on a quantity-based price adjustment formula described in the Supply Agreement whereby average per-unit prices are higher at lower volumes and lower at higher volumes. Prices are subject to adjustment for abnormal inflation (above a specified level in any year) and for certain production, schedule and other changes. See "— Changes" below.

        Due to the approaching expiration of the established pricing terms, Boeing and Spirit are in the initial stages of re-negotiating pricing for a period to be agreed upon by the parties. Boeing and Spirit are required to negotiate the pricing for such additional period in good faith based on then-prevailing U.S. market conditions for forward fuselages, B737 fuselages and B737/B777 struts and nacelles and based on then-prevailing global market conditions for all other products. If the parties are unable to agree upon pricing, then, until such dispute is resolved, pricing will be determined according to the price as of the expiration of the initial eight-year period, adjusted using the then-existing quantity-based price adjustment formula and annual escalation until such time as future pricing is agreed.

        Prices for commercial derivative models are to be negotiated in good faith by the parties based on then-prevailing market conditions. If the parties cannot agree on price, then they must engage in dispute resolution pursuant to agreed-upon procedures.

        Tooling.    Under the Supply Agreement, Boeing owns all tooling used in production or inspection of products covered by the Supply Agreement. Spirit is responsible for providing all new tooling required for manufacturing and delivering products under the Supply Agreement, and Boeing acquires title to such tooling upon completion of the manufacturing of the tools and payment by Boeing. Because Boeing owns this tooling, Spirit may not sell, lease, dispose of or encumber any of it. Spirit does, however, have the option to procure certain limited tooling needed to manufacture and deliver both Boeing and non-Boeing parts.

        Although Boeing owns the tooling, Spirit has the limited right to use this tooling without any additional charge to perform its obligations to Boeing under the Supply Agreement and also to provide aftermarket services in accordance with the rights granted to Spirit under other related agreements, including royalty-bearing license agreements. Boeing is entitled to use the tooling only under limited

circumstances. Spirit is responsible for maintaining and insuring the tooling. Spirit's rights to use the tooling are subject to the termination provisions of the Supply Agreement.

        Changes.    Upon written notification to Spirit, Boeing has the right to make changes within the general scope of work performed by Spirit under the Supply Agreement. If any such change increases or decreases the cost or time required to perform, Boeing and Spirit must negotiate an equitable adjustment (based on rates, factors and methodology set forth in the Supply Agreement) to the price or schedule to reflect the change, except that Spirit will be responsible for absorbing the cost of certain changes. The Supply Agreement also provides for equitable adjustments to product prices if there are order accelerations or decelerations, depending on lead times identified in the Supply Agreement. In addition, the Supply Agreement provides for equitable adjustments to recurring part prices as well as the price of non-recurring work upon the satisfaction of certain conditions and upon certain minimum dollar thresholds being met.

        Additional Spirit Costs.    In the event that Boeing rejects a product manufactured by Spirit, Boeing is entitled to repair or rework such product, and Spirit is required to pay all reasonable costs and expenses incurred by Boeing related thereto. In addition, Spirit is required to reimburse Boeing for costs expended in providing Spirit and/or Spirit's contractors the technical or manufacturing assistance with respect to Spirit nonperformance issues.

        Termination for Convenience.    Subject to the restrictions prohibiting Boeing from manufacturing certain products supplied by Spirit or purchasing such products from any other supplier, Boeing may, at any time, terminate all or part of any order under the Supply Agreement by written notice to Spirit. If Boeing terminates all or part of an order, Spirit is entitled to compensation for certain costs.

        Termination of Airplane Program.    If Boeing decides not to initiate or continue production of a Boeing commercial aircraft model B737, B747, B767 or B777 or commercial derivative because it determines there is insufficient business basis for proceeding, Boeing may terminate such model or derivative, including any order therefore, by written notice to Spirit. In the event of such a termination, Boeing will be liable to Spirit for any orders issued prior to the date of the termination notice and may also be liable for certain termination costs.

        Events of Default and Remedies.    It is an "event of default" under the Supply Agreement if Spirit:

(1)

fails to deliver products as required by the Supply Agreement;



(2)

fails to provide certain "assurances of performance" required by the Supply Agreement;



(3)

breaches the provisions of the Supply Agreement relating to intellectual property and proprietary information;



(4)

participates in the sale, purchase or manufacture of airplane parts without the required approval of the Federal Aviation Administration, or FAA, or appropriate foreign regulatory agency;



(5)

fails under certain requirements to maintain a system of quality assurance;



(6)

fails to comply with other obligations under the Supply Agreement (which breach continues for more than 10 days after notice is received from Boeing);



(7)

is unable to pay its debts as they become due, dissolves or declares bankruptcy; or



(8)

breaches the assignment provisions of the Supply Agreement (which breach continues for more than 10 days after notice is received from Boeing).

        If an event of default occurs, Boeing has the right to exercise various remedies set forth in the Supply Agreement, including the right to manufacture or to otherwise obtain substitute products, cancel any or all outstanding orders under the Supply Agreement, and/or terminate the Supply Agreement. Boeing is limited, however, in its ability to cancel orders or terminate the Supply Agreement for the defaults

6

---

Table of Contents

described in items (1), (2) and (6) above. In such cases, Boeing may not cancel orders unless the event of default is material and has an operational or financial impact on Boeing and may not terminate the Supply Agreement unless there are repeated, material events of default and certain other criteria are satisfied. Boeing may only terminate the Supply Agreement with respect to the aircraft program affected by the event of default. If two or more programs are affected by the event of default, Boeing may terminate the entire Supply Agreement. Boeing may also require Spirit to transfer tooling, raw material, work-in-process and other inventory and certain intellectual property to Boeing in return for reasonable compensation.

        Excusable Delay.    If delivery of any product is delayed by circumstances beyond Spirit's reasonable control, and without Spirit's or its suppliers' or subcontractors' error or negligence (including, without limitation, acts of God, war, terrorist acts, fires, floods, epidemics, strikes, unusually severe weather, riots and acts of government), or by any material act or failure to act by Boeing, each being an "excusable delay," then, subject to certain exceptions, Spirit's delivery obligations will be extended. If delivery of any product is delayed by an excusable delay for more than three months, Boeing may cancel all or part of any order for the delayed products.

        If delivery of any product constituting more than 25% of the ship set value for one or more models of program airplanes is delayed by an excusable delay for more than five months, Boeing may cancel the Sustaining SBP as it applies to such models of program airplanes, and neither party will have any liability to the other, other than as described in the above paragraph under the heading "Events of Default and Remedies."

        Assignment.    Spirit may not assign its rights under the Supply Agreement other than with Boeing's consent, which Boeing may not unreasonably withhold unless the assignment is to a disqualified person. A disqualified person is one: (1) whose principal business is as an OEM of commercial aircraft, space vehicles, satellites or defense systems; (2) that Boeing reasonably believes will not be able to perform its obligations under the Supply Agreement; (3) that, after giving effect to the transaction, would be a supplier of more than 40% by value of the major structural components of any Boeing program then in production; or (4) who is, or is an affiliate of, a commercial airplane operator or is one of five named corporate groups. Sale of majority voting power or of all or substantially all of Spirit's assets to a disqualified person is considered an assignment.

B787 Supply Agreement with Boeing

        Overview.    Spirit and Boeing also entered into a long-term supply agreement for Boeing's new B787 program, or the B787 Supply Agreement, which covers the life of the program and commercial derivatives. The B787 Supply Agreement is a requirements contract pursuant to which Spirit is Boeing's exclusive supplier for the forward fuselage, fixed and moveable leading wing edges, engine pylons and related tooling for the B787. While the B787 Supply Agreement does not provide for a minimum or maximum production rate, the agreement acknowledges that Spirit will equip itself for a maximum rate of ten aircraft per month and will negotiate with Boeing regarding an equitable price adjustment if additional revenue does not recover expenditures required to increase the production rate above that level. Pursuant to the settlement described below, Spirit has agreed to proceed with all necessary capital and equipment investments required to produce ten ship sets per month. Under the B787 Supply Agreement, Spirit also provides certain support, development and redesign engineering services to Boeing at an agreed hourly rate.

        Pricing.    Pricing for the initial configuration of the B787-8 base model that is currently in production is generally established through 2021, with prices decreasing as cumulative volume levels are met over the life of the program. Prices are subject to adjustment for abnormal inflation (above a specified level in any year) and for certain production, schedule and other specific changes, including design changes from the contract configuration baseline. As outlined in the amendment to the B787 Supply Agreement dated May 12, 2011 (the "B787 Amendment"), both parties will participate in an annual price adjustment process, which will involve an evaluation of the cost impact to Spirit as a result of changes made by Boeing. The price adjustments will be calculated using a mutually agreed methodology. The evaluations will take

place and conclude in the first quarter of each calendar year beginning in 2013 and will be applied retroactively. The parties have agreed to negotiate in good faith the prices for future commercial derivatives such as the B787-9, based on principles consistent with the B787 Supply Agreement terms as they relate to the B787-8 model.

        Advance Payments/Deferred Revenue.    In December 2010, Spirit and Boeing entered into a memorandum of agreement ("MOA") and a settlement agreement regarding certain claims associated with the development and production of the B787 airplane. As part of these agreements, Spirit received a payment for $236.2 million which was recorded as deferred revenue (short-term) within the December 31, 2010 consolidated balance sheet pending finalization of a contract amendment, which would contain the final settlement terms. On May 12, 2011, Spirit and Boeing entered into the B787 Amendment, which finalized substantially all of the provisions of the December 2010 MOA. Among other things, the B787 Amendment spread out repayment of a $700.0 million cash advance made by Boeing to Spirit in 2007 to be offset against the purchase price of the first 1,000 B787 ship sets delivered to Boeing, instead of the first 500 ship sets. In the event Boeing does not take delivery of 1,000 ship sets prior to the termination of the B787 program or the B787 Supply Agreement, any advances not then repaid will be applied against any outstanding payments then due by Boeing to us, and any remaining balance will be repaid in annual installments of $42.0 million due on December 15th of each year until the advance payments have been fully recovered by Boeing. Advance payments made to Spirit in 2008 in the amount of $396.0 million for production articles were applied against the full purchase price of ship sets delivered and were fully liquidated by December 31, 2011. During the third quarter of 2011, cash payments for the B787 units resumed. The B787 Amendment also changed the treatment of advances paid by Boeing for certain non-recurring work into a nonrefundable payment in full for such work. Our financial results for 2011 incorporate the provisions of this B787 Amendment as described under "Management's Discussion and Analysis of Financial Condition and Results of Operations," "— Results of Operations" and "— Liquidity and Capital Resources".

        Accordingly, portions of the advance repayment liability are included as current and long-term liabilities in our consolidated balance sheet. As of December 31, 2011, the amount of advance payments and deferred revenue received by us from Boeing under the B787 Supply Agreement and not yet repaid or recognized as revenue was approximately $629.1 million.

        Termination of Airplane Program.    If Boeing decides not to continue production of the B787 airplane program because it determines, after consultation with Spirit, that there is an insufficient business basis for proceeding, Boeing may terminate the B787 airplane program, including any orders, by written notice to Spirit. In the event of such a termination, Boeing will be liable to Spirit for costs incurred in connection with any orders issued prior to the date of the termination notice and may also be liable for certain termination costs and for compensation for any tools, raw materials or work-in-process requested by Boeing in connection with the termination.

        Events of Default and Remedies.    It is an "event of default" under the B787 Supply Agreement if Spirit:

(1)

fails to deliver products as required by the B787 Supply Agreement;



(2)

breaches the provisions of the B787 Supply Agreement relating to intellectual property and proprietary information;



(3)

participates in the sale, purchase or manufacture of airplane parts without the required approval of the FAA or appropriate foreign regulatory agency;



(4)

fails under certain requirements to maintain a system of quality assurance;



(5)

fails to comply with other obligations under the B787 Supply Agreement (which breach continues for more than 15 days after notice is received from Boeing);



(6)

is unable to pay its debts as they become due, dissolves or declares bankruptcy;

8

Table of Contents

(7)

fails to comply with U.S. export control laws; or



(8)

breaches the assignment provisions of the B787 Supply Agreement.

        If an event of default occurs, Boeing has the right to exercise various remedies set forth in the B787 Supply Agreement, including the right to manufacture or to otherwise obtain substitute products, cancel any or all outstanding orders under the B787 Supply Agreement and/or terminate the B787 Supply Agreement. Before terminating any order or the B787 Supply Agreement, Boeing is required to work with Spirit to attempt to agree on a satisfactory recovery plan. Boeing may also require Spirit to transfer tooling, raw material, work-in-process and other inventory and certain intellectual property to Boeing in return for reasonable compensation.

        Assignment.    Spirit may not assign its rights under the B787 Supply Agreement or any related order other than with Boeing's consent, which Boeing may not unreasonably withhold unless the assignment is to a disqualified person. A disqualified person is one: (1) whose principal business is as an OEM of commercial aircraft, space vehicles, satellites or defense systems; (2) that Boeing reasonably believes will not be able to perform its obligations under the B787 Supply Agreement; (3) that, after giving effect to the transaction, would be a supplier of more than 40% by value of the major structural components of any Boeing program then in production; or (4) who is, or is an affiliate of, a commercial airplane operator or is one of five named corporate groups. Sale of majority voting power or of all or substantially all of Spirit's assets to a disqualified person is considered an assignment.

License of Intellectual Property

        Supply Agreement.    All technical work product and works of authorship produced by or for Spirit with respect to any work performed by or for Spirit pursuant to the Supply Agreement are the exclusive property of Boeing. All inventions conceived by or for Spirit with respect to any work performed by or for Spirit pursuant to the Supply Agreement and any patents claiming such inventions are the exclusive property of Spirit, except that Boeing will own any such inventions that Boeing reasonably believes are applicable to the B787 platform, and Boeing may seek patent protection for such B787 inventions or hold them as trade secrets, provided that, if Boeing does not seek patent protection, Spirit may do so.

        Except as Boeing otherwise agrees, Spirit may only use Boeing proprietary information and materials (such as tangible and intangible confidential, proprietary and/or trade secret information and tooling) in the performance of its obligations under the Supply Agreement. Spirit is prohibited from selling products manufactured using Boeing proprietary information and materials to any person other than Boeing without Boeing's authorization.

        Spirit has granted to Boeing a license to Spirit proprietary information and materials and software and related products for use in connection with the testing, certification, use, sale or support of a product covered by the Supply Agreement, or the manufacture, testing, certification, use, sale or support of any aircraft including and/or utilizing a product covered by the Supply Agreement. Spirit has also granted to Boeing a license to use Spirit intellectual property to the extent such intellectual property interferes with Boeing's use of products or intellectual property belonging to Boeing under the Supply Agreement.

        To protect Boeing against Spirit's default, Spirit has granted to Boeing a license, exercisable on such default to practice and/or use, and license for others to practice and/or use on Boeing's behalf, Spirit's intellectual property and tooling related to the development, production, maintenance or repair of products in connection with making, using and selling products. As a part of the foregoing license, Spirit must, at the written request of and at no additional cost to Boeing, promptly deliver to Boeing any such licensed property considered by Boeing to be necessary to exercise Boeing's rights under the license.

        B787 Supply Agreement.    The B787 Supply Agreement establishes three classifications for patented invention and proprietary information: (1) intellectual property developed by Spirit during activity under the B787 Supply Agreement, or Spirit IP; (2) intellectual property developed jointly by Boeing and Spirit during that activity, or Joint IP; and (3) all other intellectual property developed during activity under the B787 Supply Agreement, or Boeing IP.

Table of Contents

        Boeing may use Spirit IP for work on the B787 program and Spirit may license it to third parties for work on such program. Spirit may also not unreasonably withhold consent to the license of such intellectual property to third parties for work on other Boeing programs, provided that it may require a reasonable royalty to be paid and, with respect to commercial airplane programs, that Spirit has been offered an opportunity, to the extent commercially feasible, to work on such programs.

        Each party is free to use Joint IP in connection with work on the B787 and other Boeing programs, but each must obtain the consent of the other to use it for other purposes. If either party wishes to license Joint IP to a third party for work on a Boeing program other than the B787, then the other party may require a reasonable royalty, but may not unreasonably withhold its consent, as long as (if the program in question is another Boeing commercial airplane program) Spirit has been offered an opportunity, to the extent commercially feasible, to perform work for the particular program.

        Spirit is entitled to use Boeing IP for the B787 program, and may require Boeing to license it to subcontractors for the same purpose.

        Additional License From Boeing.    Boeing has licensed certain intellectual property rights to Spirit under a Hardware Material Services General Terms Agreement, or HMSGTA, and four initial Supplemental License Agreements, or SLAs, under the HMSGTA. The HMSGTA and the initial SLAs grant Spirit licenses to use Boeing intellectual property to manufacture listed parts for the aftermarket and to perform maintenance, repair and overhaul, or MRO, of aircraft and aircraft components for customers other than Boeing. These agreements also permit Spirit to use knowledge obtained by Spirit personnel prior to the closing of the Boeing Acquisition. Spirit also may obtain additional SLAs from Boeing and those SLAs will also supersede the restrictions on Spirit's use of Boeing's proprietary information and materials described above.

Intellectual Property

        We have several patents pertaining to our processes and products. While our patents, in the aggregate, are of material importance to our business, no individual patent or group of patents is of material importance. We also rely on trade secrets, confidentiality agreements, unpatented knowledge, creative products development and continuing technological advancement to maintain our competitive position.

Our Products

        We are organized into three principal reporting segments: (1) Fuselage Systems, which includes forward, mid and rear fuselage sections; (2) Propulsion Systems, which includes nacelles, struts/pylons and engine structural components; and (3) Wing Systems, which includes wing systems and components, flight control surfaces and other miscellaneous structural parts. The Fuselage Systems segment manufactures products at our facilities in Wichita, Kansas and Kinston, North Carolina, with an assembly plant for the A350 XWB in Saint-Nazaire, France. The Propulsion Systems segment manufactures products at our facilities in Wichita, Kansas, and the Wing Systems segment manufactures products at our facilities in Tulsa and McAlester, Oklahoma; Prestwick, Scotland; Subang, Malaysia and Kinston, North Carolina. Fuselage Systems, Propulsion Systems and Wing Systems represented approximately 50%, 25%, and 25%, of our net revenues for the twelve months ended December 31, 2011, respectively. All other activities fall within the All Other segment, representing less than 1% of our net revenues for the twelve months ended December 31, 2011, principally made up of sundry sales of miscellaneous services, tooling contracts, and sales of natural gas through a tenancy-in-common with other companies that have operations in Wichita.

Commercial Aircraft Structures

        We principally design, engineer and manufacture commercial aircraft structures such as fuselages, nacelles (including thrust reversers), struts/pylons, wings and wing assemblies and flight control surfaces. We are the largest independent supplier of aerostructures to Boeing and one of the largest independent suppliers of aerostructures to Airbus. Sales related to the commercial aircraft structures market, some of

which may be used in military applications, represented approximately 99% of our net revenues for the year ended December 31, 2011.

        Our structural components, in particular the forward fuselage and nacelles, are among the most complex and highly engineered structural components and represent a significant percentage of the costs of each aircraft. We are currently the sole-source supplier of 97% of the products we sell to Boeing and Airbus, as measured by dollar value of products sold. We typically sell a package of aerostructure components, referred to as a ship set, to our customers.

        The following table summarizes the major commercial (including derivatives, regional and announced business jets) programs that we currently have under long-term contract by product and aircraft platform.

Our Competitive Strengths

        We believe our key competitive strengths include:

        Leading Position in the Growing Commercial Aerostructures Market.    We are one of the largest independent non-OEM commercial aerostructures manufacturer with an estimated 16% market share of the global market. Based on their published aircraft backlog figures, Boeing and Airbus had a combined backlog of 8,208 commercial aircraft as of December 31, 2011, and 6,995 commercial aircraft as of December 31, 2010. We are under contract to provide aerostructure products for approximately 98% of the aircraft that comprise this commercial aircraft backlog. We are currently the sole-source supplier of 97% of the products we sell to Boeing and Airbus, as measured by dollar value of the products sold. The significant Boeing and Airbus aircraft order backlog for scheduled deliveries between 2012-2014, and our strong relationships with Boeing and Airbus, should enable us to continue to profitably grow our core commercial aerostructures business.

        Participation on High-Volume and Major Growth Platforms.    We derive a high proportion of our Boeing revenues from the high-volume B737 program and a high proportion of our Airbus revenues from the high-volume A320 program. Boeing's backlog consists of over 2,365 B737s (more than five years of backlog at current build rates) and Airbus' backlog consists of approximately 2,752 A320s (more than five years of backlog at current build rates). The B737 and A320 families are Boeing's and Airbus' best-selling commercial airplanes, respectively. We have also been awarded a significant amount of work on major twin-aisle programs, the B777, B787 and A350 XWB.

        Stable Base Business.    We have entered into exclusive long-term supply agreements with Boeing and Airbus, our two largest customers, making us the exclusive supplier for most of the products covered by these contracts. Our supply agreements with Boeing provide that we will continue to supply essentially all of the products we currently supply to Boeing for the life of the current aircraft programs, including commercial derivative models. The principal supply agreements we have entered into with Boeing make us Boeing's exclusive source for substantially all of the products covered by the agreements.

        Under our supply agreements with Airbus, we supply most of our products for the life of the aircraft program, including commercial derivative models. For the A380 and A350 XWB, we have long-term requirements contracts with Airbus that cover a fixed number of units. We are currently the sole-source supplier for approximately 75% of the products, as measured by dollar volume, that we sell to Airbus.

        Strong Incumbent and Competitive Position.    We have a strong incumbent position on the products we currently supply to Boeing and Airbus, forged by long-standing relationships and long-term supply agreements with Boeing and Airbus. Many members of our management team have a long history of working with Boeing and Airbus as employees of our predecessors, Boeing Wichita and BAE Aerostructures. Our relationship with Boeing is further strengthened by the fact that many members of our senior management team are former Boeing executives or managers. We believe our senior management team possesses inherent knowledge of and relationships with Boeing and Airbus that may not exist to a corresponding degree between other suppliers and these two OEMs.

        We believe that OEMs incur significant costs to change aerostructures suppliers once contracts are awarded. Such changes after contract award require additional testing and certification, which may create production delays and significant costs for both the OEM and the new supplier. We also believe it would be cost prohibitive for other suppliers to duplicate our facilities and the over 20,000 major pieces of equipment that we own or operate. The combined insurable replacement value of all the buildings and equipment we own or operate is approximately $5.8 billion, including approximately $2.4 billion for buildings, approximately $1.9 billion for equipment that we own and approximately $1.5 billion for other equipment used in the operation of our business. The insurable values represent the estimated replacement cost of buildings and equipment used in our operations and covered by property insurance, and exceed the fair value of assets acquired as determined for financial reporting purposes. As a result, we believe that as long as we continue to meet our customers' requirements, the probability that they change

13

Table of Contents

suppliers on our current statement of work is quite low. Our incumbent position also provides us with a competitive advantage with respect to new business from our customers.

        Industry-Leading Technology, Design Capabilities and Manufacturing Expertise.    Our predecessor, Boeing Wichita, had over 75 years of experience designing and manufacturing large-scale, complex aerostructures and we possess industry-leading engineering capabilities that include significant expertise in structural design and technology, use of metallic and composite materials, stress analysis, systems engineering and acoustics technology. With approximately 1,700 degreed engineering and technical employees (including approximately 80 degreed contract engineers and access to 116 degreed engineers from Spirit-Progresstech, our joint venture with Progresstech LTD), we possess knowledge and manufacturing know-how that customers depend on and would be difficult for other suppliers to replicate. In addition to our engineering expertise, we have strong manufacturing and technological capabilities. Our manufacturing processes are highly automated, delivering efficiency and quality, and we have expertise in manufacturing aerostructures using both metallic and composite materials. We have strong technical expertise in bonding and metals fabrication, assembly, tooling and composite manufacturing, including the handling of all composite material grades and fabricating large-scale complex contour composites. We provide aftermarket support for the products we design and build.

        We believe our technological, engineering and manufacturing capabilities separate us from many of our competitors and give us a significant competitive advantage to grow our business and increase our market share. The fact that we are one of the major external suppliers of forward fuselages for large commercial aircraft demonstrates our industry leadership. The forward fuselage is one of the most complex and technologically advanced aerostructures on a commercial aircraft because it must satisfy the aircraft's contour requirements, balance strength, aerodynamics and weight, and house the cockpit and avionics.

        Competitive and Predictable Cost Structure.    Following the Boeing Acquisition, we entered into new labor contracts with our unions that established wage levels that are aligned with the local market. We also changed work rules and significantly reduced the number of job categories, resulting in greater flexibility in work assignment programs and increased productivity. In 2010 and 2011, we successfully negotiated long-term labor agreements with our factory and office workers in Kansas and Oklahoma, which represents approximately 88% of our total represented workforce. As a result, we expect our labor costs to be stable and predictable through 2019.

        We have also continued to implement a number of operational efficiency improvements, including global sourcing to reduce supplier costs. It is our belief that our competitive cost structure has positioned us to win new business.

        Experienced Management Team.    We have an experienced and proven management team with an average of more than 25 years each of aerospace industry experience. Our management team has successfully expanded our business, reduced costs and established the stand-alone operations of our business. Many of our executives and senior managers have lengthy experience working for or with our primary customers, including Boeing and Airbus, which provides us with detailed insight into how we can better serve our customers.

Our Business Strategy

        Our goal is to remain a leading aerostructures manufacturer and to increase revenues while maximizing our profitability and growth. Our strategy includes the following:

        Support Increased Aircraft Deliveries.    Our determination to meet or exceed the expectations of Boeing, Airbus and our other existing customers continues as our core business strategy. Our customers expect us to deliver high-quality products on schedule. We constantly focus on improving our manufacturing efficiency, maintaining our high standards of quality, and delivering our products on-time to meet these expectations. With the significant levels of Boeing and Airbus announced production rate

increases on certain programs, we expect our output to grow on the programs year over year for the next three to five years. We are focused on supporting our customers' increase in new aircraft production that includes the B787, Gulfstream G280, G650 and A350 XWB, as well as key programs that include the Boeing B737, B777, and the Airbus A320. We are improving our manufacturing processes, properties and facilities to accommodate these increases in production and the change in model mix of existing aircraft. For the twelve months ended December 31, 2011, we delivered 520 Boeing ship sets (one ship set represents a full set of components for one airplane), as compared to 480 Boeing ship sets for the twelve months ended December 31, 2010. Deliveries of Airbus products began in April 2006, with the acquisition of BAE Aerostructures. For the twelve months ended December 31, 2011, we delivered 520 Airbus ship sets, compared to 458 Airbus ship sets for the twelve months ended December 31, 2010. We believe we are well positioned to meet the increased demand for our products by our customers.

        Win New Business from Existing and New Customers.    We have established a sales and marketing infrastructure to support our efforts to win business from our new and existing customers. We believe that we are well positioned to win additional work from Boeing and Airbus, given our strong relationships, our size, design and build capabilities and our financial resources. We believe that opportunities for increased business from our customers will arise on work that they currently produce internally and may shift to an external supplier in the future and work on new aircraft programs. We also have significant opportunities to increase our sales to OEMs other than Boeing and Airbus and have significant opportunities to grow business outside our core programs. We believe our design, engineering and manufacturing capabilities are highly attractive to potential new customers and provide a competitive cost position and sales and marketing efforts, and we have won several significant contracts from non-Boeing customers through competitive bids since the Boeing Acquisition. Design techniques and processes that were developed in the high-volume large commercial market sector are now being introduced to the business jet, regional jet, military and helicopter markets. These very competitive design techniques are largely new to these sectors and make Spirit attractive to this new group of customers. For example, the helicopter and military markets have begun to incorporate composite aerostructures, with which we have experience in the large commercial market, into their designs. Our customer base has expanded to include Sikorsky, Rolls-Royce, Gulfstream, Bombardier, Mitsubishi Aircraft Corporation, Southwest Airlines, Continental Airlines and American Airlines.

        Large Commercial Airplanes: We believe that Spirit is well positioned to win additional work from Boeing and Airbus, particularly work they currently in-source, but may potentially shift to an external supplier in the future as well as work on new aircraft programs. Our research shows that the underlying procurement trend will continue to be toward increased outsourcing. In addition, opportunities for us to win significant new business will typically arise when large commercial airplane OEMs design new aircraft programs, or a new aircraft derivative, such as cargo versions of passenger aircraft, larger or extended range versions of in-production airplanes, and military versions of commercial airplanes. Suppliers to aircraft OEMs must meet demanding quality and reliability standards, and our record of meeting those standards with Boeing and Airbus is a key competitive strength. We believe these strengths position us well to increase our statements of work from our customers. In addition, our strong relationships, size, design and build capabilities, and financial resources, create a competitive advantage for us. In 2011, Spirit was selected by Boeing to join the B737 Max and B767 Tanker teams providing major fuselage, propulsion and wing components.

        Business & Regional Jets: We have continued to expand our presence into the business and regional jet markets with Propulsion contracts from three major OEMs (Rolls-Royce, Mitsubishi and Bombardier) and Aerostructures contracts for two new Gulfstream programs (G280 and G650). Although the business jet market has been slower to recover than civil transport, Spirit believes that it is well positioned to respond to the volume production which may ultimately be required in this sector.

        Military/Helicopter: We have also been able to apply high-volume commercial techniques to provide very competitive designs for our customers in the military and helicopter markets. For example, Spirit won a competitive bid to build the cockpit and the entire cabin assembly for the Sikorsky CH-53K helicopter

development program. We design, tool and build the flight test articles in the development program, with potential for the production contract when it is awarded.

        On the Navy P-8A program, we are building fuselage, propulsion and wing ship sets. By using the current 737NG assembly line, we are able to produce the military specific aircraft at much lower commercial costs, providing our customer competitive value.

        Research and Development Investment in Next-Generation Technologies.    We invest in research and development for current programs to strengthen our relationships with our customers and in new programs to generate new business. We are currently developing proprietary Spirit intellectual property ("IP") that we will be able to use for our current and future customers. To maximize our research and development efforts and the resulting IP, we work closely with OEMs and integrate our engineering teams into their design processes. We believe our close coordination with OEMs positions us to win new business on new commercial and military platforms. Each of our business segments has a specific five-year technology road map as well as a longer term team developing the future technologies that will support and build our growth plans.

        Provide New Value-Added Services to our Customers.    We possess the core competencies not only to manufacture, but also to design, integrate and assemble complex system and structural components. We assemble and integrate avionics, electrical systems, hydraulics, wiring and other components for the forward fuselage and pylons for the Boeing B787. We believe our ability to integrate complex components into aerostructures is a service that greatly benefits our customers by reducing their flow time and inventory holding costs. As a result of our ability to integrate and assemble components from a diverse supplier base, we believe we are integral to our customers' supply chains. We also intend to increase our aftermarket sales of the products we manufacture and have developed a global direct sales and marketing channel. In addition, we also produce spares for certain out of production aircraft and regional/business jet programs.

        Continued Improvement to our Low-Cost Structure.    We remain focused on further reducing costs and we have identified and begun to implement several such opportunities in our business. We expect that most of our future cost-saving opportunities will arise from increased productivity, continued outsourcing of non-core activities, and improved procurement and sourcing through our global sourcing initiatives. We believe our strategic sourcing expertise should allow us to develop and manage low-cost supply chains in Asia and Central Europe. As part of our plans for low-cost supply chains, we opened a manufacturing plant in Subang, Malaysia in 2009, which is focused on building composite assemblies. One of our goals is to continue to increase our material sourcing from low-cost jurisdictions.

        Pursue Acquisitions on a Strategic Basis.    The commercial aerostructures market is highly fragmented, with many small private businesses and divisions of larger public companies. Given this market fragmentation, coupled with the trend by OEMs to outsource work to larger Tier 1 manufacturers that coordinate suppliers and integrate into airframes, we believe our industry could experience significant consolidation in the coming years. Although our main focus is to grow our business organically, we believe we are well positioned to capture additional market share and diversify our current business through opportunistic strategic acquisitions.

Operating Segments

        We operate in three principal segments: Fuselage Systems, Propulsion Systems and Wing Systems. Substantially all revenues in the three principal segments are with Boeing, with the exception of Wing Systems, which includes revenues from Airbus and other customers. We serve customers in addition to Boeing and Airbus across our three principal segments; however, these customers currently do not represent a significant portion of our revenues, and are not expected to in the near future. All other activities fall within the All Other segment, principally made up of sundry sales of miscellaneous services, tooling contracts, and sales of natural gas through a tenancy-in-common with other companies that have operations in Wichita, Kansas.

16

---

Table of Contents

        The Fuselage Systems segment includes development, production and marketing of forward, mid and rear fuselage sections and systems, primarily to aircraft OEMs, as well as related spares and MRO. The Fuselage Systems segment manufactures products at our facilities in Wichita, Kansas; Kinston, North Carolina and Saint-Nazaire, France.

        The Propulsion Systems segment includes development, production and marketing of struts/pylons, nacelles (including thrust reversers) and related engine structural components primarily to aircraft or engine OEMs, as well as related spares and MRO services. The Propulsion Systems segment manufactures products at our facilities in Wichita, Kansas.

        The Wing Systems segment includes development, production and marketing of wings and wing components (including flight control surfaces) and other miscellaneous structural parts primarily to aircraft OEMs, as well as related spares and MRO services. These activities take place at the Company's facilities in Tulsa and McAlester, Oklahoma; Kinston, North Carolina; Prestwick, Scotland and Subang, Malaysia.

Sales and Marketing

        Our established sales and marketing infrastructure supports our efforts to expand our business with new and existing customers in three sectors of the aerostructures industry: (1) large commercial airplanes, (2) business and regional jets and (3) military/helicopter. The sales directors establish and maintain relationships with individual customers and are supported in their campaigns by sales teams within specific product specialties and a market research team performing various analyses related to those products and customers. The comprehensive sales and marketing teams work closely to ensure a consistent, single message approach with customers.

        Although we have long-term contracts with Boeing and Airbus on programs such as the B737, B787, A320, A350 XWB and A380, and OEMs generally desire to minimize costs by retaining established aerostructure suppliers, our sales and marketing team continues to maintain strong relationships with the OEMs to position us for future business opportunities. Our marketing team continues to research and analyze trends in our industry and in new product development, and our sales team maintains regular contact with key Boeing and Airbus decision-makers to prepare for new business opportunities from both companies.

        We maintain a customer contact database to maximize our interactions with existing and potential customers. In the time that Spirit has existed as an independent company, we have been successful in building a positive identity and name recognition for the Company brand through advertising, trade shows, sponsorships and Spirit customer events. In order to diversify and win new customers, we market our expertise in the design and manufacture of major aerostructures and advanced manufacturing capabilities with both composites and traditional metals processes.

Customers

        Our primary customers are aircraft OEMs. Boeing and Airbus are our two largest customers. We are the largest independent aerostructures supplier to Boeing and one of the largest independent suppliers to Airbus. We entered into long-term supply agreements with our customers to provide aerostructure products to aircraft programs. As of December 31, 2011, virtually all of the products we sell are under long-term contracts and 97% of those products, as measured by dollar value of products sold, are supplied by us on a sole-sourced basis.

        We have good relationships with our customers due to our diverse product offerings, leading design and manufacturing capabilities using both metallic and composite materials, and competitive pricing.

        Boeing.    For the twelve months ended December 31, 2011, approximately 85% of our revenues were from sales to Boeing. We have a strong relationship with Boeing given our predecessor's 75+ year history as a Boeing division. Many members of our senior management team are former Boeing executives or

Table of Contents

managers who have longstanding relationships with Boeing and continue to work closely with Boeing. As part of the Boeing Acquisition, we entered into a long-term supply agreement under which we are Boeing's exclusive supplier for substantially all of the products and services provided by Boeing Wichita prior to the Boeing Acquisition for the life of the programs. In addition, Boeing selected us to be the design leader for the Boeing B787 forward fuselage based in part on our expertise with composite technologies.

        We believe our relationship with Boeing is unmatched in the industry and will allow us to continue to be an integral partner with Boeing in the designing, engineering and manufacturing of complex aerostructures.

        Airbus.    For the twelve months ended December 31, 2011, approximately 10% of our revenues were from sales to Airbus. As a result of the BAE Acquisition, we became one of the largest independent aerostructures suppliers to Airbus, and we have expanded our relationship through new business wins. Under our supply agreement with Airbus, we supply products for the life of the aircraft program, including commercial derivative models, with pricing determined through 2015. For the A350 XWB and A380 programs, we have long-term requirements contracts with Airbus that cover a fixed number of units. We believe we can leverage our relationship with Airbus and our history of delivering high-quality products to further increase our sales to Airbus and continue to partner with Airbus on new programs going forward.

        We are a significant supplier of the composite fuselage structure for the new Airbus A350 XWB. To accommodate this and other work, we expanded our operations in 2011 with the opening of a new manufacturing facility in Kinston, North Carolina and a new assembly plant in Saint-Nazaire, France, which will assemble the center fuselage sections it receives from the Kinston, North Carolina facility before transporting the completed assembled unit to Airbus. In addition, we have a contract with Airbus to design and manufacture a major wing structure for the A350 XWB program. Spirit Europe designs and assembles the wing leading edge structure primarily at its facility in Prestwick, Scotland. The composite front spar is built at the facility in Kinston, North Carolina with sub-assemblies being manufactured at the Spirit AeroSystems Malaysia facility in Subang, Malaysia.

        Although most of our revenues are obtained from sales inside the U.S., we generated $653.1 million, $498.4 million, and $575.9 million in sales to international customers for the twelve months ended December 31, 2011, December 31, 2010, and December 31, 2009, respectively, primarily to Airbus.

        The following chart illustrates the split between domestic and foreign revenues (dollars in millions):

(1)

Revenues are attributable to countries based on the destination where goods are delivered.

        The international revenue is included primarily in the Wing Systems segment. All other segment revenues are primarily from U.S. sales. Approximately 6% of our total assets based on book value are located in the United Kingdom as part of Spirit Europe with approximately another 5% of our total assets located in countries outside the United States and the United Kingdom.

Expected Backlog

        As of December 31, 2011, our expected backlog associated with large commercial aircraft, regional jet, business jet, and military equipment deliveries through 2016, calculated based on contractual product prices and expected delivery volumes, was approximately $31.8 billion. This is an increase of $3.5 billion from our corresponding estimate as of the end of 2010 reflecting the fact that Airbus and Boeing new orders exceeded deliveries in 2011. Backlog is calculated based on the number of units Spirit is under contract to produce on our fixed quantity contracts, and Boeing and Airbus announced backlog on our supply agreements. The number of units may be subject to cancellation or delay by the customer prior to shipment, depending on contract terms. The level of unfilled orders at any given date during the year may be materially affected by the timing of our receipt of firm orders and additional airplane orders, and the speed with which those orders are filled. Accordingly, our expected backlog as of December 31, 2011 may not necessarily represent the actual amount of deliveries or sales for any future period.

precision metal forming producing complex contoured shapes in sheet metal and extruded aluminum.

        Our manufacturing expertise is supported by our state-of-the-art equipment. We have over 20,000 major pieces of equipment installed in our customized manufacturing facilities. For example, for the manufacture of the B787 composite forward fuselage, we installed a 30-foot diameter by 70-foot long autoclave, which is one of the largest autoclaves in the world. An autoclave is an enclosure device that generates controlled internal heat and pressure conditions used to cure and bond certain resins and is used in the manufacture of composite structures. We installed a comparable autoclave as well as other specialized machines in Kinston, North Carolina to support our work on the A350 XWB. We intend to continue to make the appropriate investments in our facilities to support and maintain our industry-leading manufacturing expertise.

Engineering

        We have approximately 1,700 engineers and technical employees, including over 80 contract engineers. In addition, we currently contract the work of approximately 685 engineers from engineering services firms worldwide, including 116 engineers through Spirit-Progresstech LLC, a joint venture we entered into with Progresstech LTD of Moscow, Russia in November 2007. We also employ 24 technical fellows, who are experts in engineering and keep the Company current with new technology by producing technical solutions for new and existing products and processes; 11 FAA designated engineering representatives ("DER"), experienced engineers appointed by the FAA to approve engineering data used for certification; and 12 authorized representatives, who possess the same qualifications and perform the same certification functions as DERs, but with authority from the Boeing Certification and Compliance

Organization. The primary purpose of the engineering organization is to provide continuous support for ongoing design, production and process improvements. We possess a broad base of engineering skills in metal and composite fabrication and assembly, chemical processing and finishing, tooling design and development, and quality and precision measurement technology, systems and controls.

        Our engineering organization is composed of four primary groups, including: (1) Structures Design and Drafting, which focuses on production support, customer introductions, design-for-manufacturing and major product derivatives; (2) Structures Technology, which focuses on overall structural integrity over the lifecycle of the airframe through stress and durability analysis, damage tolerance analysis and vibration testing; (3) Manufacturing Engineering, responsible for applying lean manufacturing techniques, interpreting design drawings and providing manufacturing sequence work plans; and (4) Liaison, Lab and Materials, Processes and Standards, which conducts research into defects discovered by quality assurance through analytical chemistry, metallurgical, static and dynamic testing and full-scale testing.

        We believe our leading engineering capabilities are a key strategic factor differentiating us from some of our competitors.

Research and Development

        We believe that world-class research and development helps to maintain our position as an advanced partner to our OEM customers' new product development teams. As a result, we spend significant capital and financial resources on our research and development, including approximately $35.7 million during the year ended December 31, 2011, approximately $51.5 million during the year ended December 31, 2010, and approximately $56.7 million during the year ended December 31, 2009. Through our research, we strive to develop unique intellectual property and technologies that will improve our OEM customers' products and, at the same time, position us to win work on new products. Our development effort, which is an ongoing process that helps us reduce production costs and streamline manufacturing, is currently focused on preparing for initial production of new products and improving manufacturing processes on our current work.

        Our research and development is geared toward the architectural design of our principal products: fuselage systems, propulsion systems and wing systems. We are currently focused on research in areas such as advanced metallic joining, low-cost composites, acoustic attenuation, efficient structures, systems integration, advanced design and analysis methods, and new material systems. Other items that are expensed relate to research and development that is not funded by the customer. We collaborate with universities, research facilities and technology partners in our research and development.

Suppliers and Materials

        The principal raw materials used in our manufacturing operations are aluminum, titanium, and carbon fiber. We also purchase metallic parts, non-metallic parts, and machined components. In addition, we procure subassemblies from various manufacturers which are used in the final aerostructure assembly.

        Currently we have approximately 1,500 active manufacturing suppliers. No one supplier represents more than 3% of our total cost of sales. Our strategy is to enter into long-term contracts with suppliers to secure competitive pricing. Our exposure to rising costs of raw material is limited to some extent through leveraging relationships with our OEM's high-volume contracts.

        We continue to seek and develop sourcing opportunities from North America to Europe and Asia to achieve a competitive global cost structure. Over 25 countries are represented in our international network of suppliers.

Environmental Matters

        Our operations and facilities are subject to various environmental, health and safety laws and regulations, including federal, state, local and foreign government requirements, governing, among other

20

Table of Contents

matters, the emission, discharge, handling and disposal of regulated materials, the investigation and remediation of contaminated sites, and permits required in connection with our operations. Our operations are designed, maintained and operated to promote protection of human health and the environment. Although we believe that our operations and facilities are in material compliance with applicable environmental and worker protection laws and regulations, management cannot provide assurance that future changes in such laws or their enforcement, or the nature of our operations will not require us to make significant additional expenditures to ensure continued compliance. Further, we could incur substantial costs, including costs to reduce air emissions, clean-up costs, fines and sanctions, and third-party property damage or personal injury claims as a result of violations of or liabilities under environmental laws, relevant common law or the environmental permits required for our operations.

        New regulations or more stringent enforcement of existing requirements could also result in additional compliance costs. For example, various governments have enacted or are considering enactment of laws to reduce emissions of carbon dioxide and other so-called greenhouse gases ("GHG"). In particular, the U.S. Environmental Protection Agency (the "EPA") has promulgated new regulations that require certain of our facilities to report annual GHG emissions and will require new operating permits to be issued for those facilities. In the absence of a national price for carbon-based air pollutant emissions, new legislation from Congress, or information relative to additional regulation from the EPA, we are not in a position at this time to estimate the costs which may result from these or similar actions.

United States

        Under some environmental laws in the United States, a current or previous owner or operator of a contaminated site may be held liable for the entire cost of investigation, removal or remediation of regulated materials at such property, whether or not the owner or operator knew of, or was responsible for, the presence of such regulated materials. Persons who arrange for disposal or treatment of hazardous materials also may be liable for the costs of investigation, removal or remediation of those substances at a disposal or treatment site, regardless of whether the affected site is owned or operated by them. Because we own and/or operate a number of facilities that have a history of industrial or commercial use and because we arrange for the disposal of regulated materials at many disposal sites, we may and do incur costs for investigation, removal and remediation.

        The Asset Purchase Agreement for the Boeing Acquisition, referred to herein as the "Asset Purchase Agreement", provides, with limited exceptions, that Boeing is responsible for environmental liabilities relating to conditions existing at the Wichita, Kansas and Tulsa and McAlester, Oklahoma facilities as of the Boeing Acquisition date. For example, Boeing is subject to an administrative consent order issued by the Kansas Department of Health and Environment, or KDHE, to contain and clean up contaminated groundwater, which underlies a majority of the Wichita site. Pursuant to the KDHE order, Boeing has a long-term remediation plan in place, and containment and remediation efforts are underway. We are responsible for any environmental conditions that we cause at these facilities following the Boeing Acquisition.

United Kingdom

        In the United Kingdom, remediation of contaminated land may be compelled by the government in certain situations. If a property is to be redeveloped, the local authority, in its planning role, may require remediation as a condition to issuing a permit. In addition, in situations in which the contamination is causing harm to human health or polluting the environment, the local authority may use its environmental legislative powers to force remediation so that the impacted areas are "suitable for use." If contamination is polluting the property of a third party or causing loss, injury or damage, the third party may file an action against the owner or operator of the source in common law based on negligence or nuisance to recover the value of the loss, injury or damage sustained.

        Prestwick Facility.    BAE Systems indemnified us, subject to certain contractual limitations and conditions, for any clean-up costs and other losses, liabilities, expenses and claims related to existing pollution at the Prestwick facility, existing pollution that migrates from the Prestwick facility to a third party's property and any pollution that migrates to the Prestwick facility from the property retained by BAE Systems. Subject to certain exceptions, the indemnity has an aggregate liability cap of £40.0 million. As of December 31, 2011, we do not anticipate reaching the liability cap.

Other International Sites

        Our interests in other international sites are subject to foreign government environmental laws and regulations. It is our policy and practice to comply with all requirements, both domestic and international. We believe that our procedures are properly designed to prevent unreasonable risk of environmental damage and resulting financial liability in connection with our business.

Competition

        Although we are one of the largest independent non-OEM aerostructures suppliers, based on annual revenues, with an estimated 16% share of the global aerostructures market, this market remains highly competitive and fragmented. Our primary competition currently comes from either work performed by internal divisions of OEMs or third-party aerostructures suppliers, but direct competition continues to grow.

        Our principal competitors among OEMs include Airbus, Boeing, Dassault Aviation, Embraer Brazilian Aviation Co., Gulfstream Aerospace Co., Hawker Beechcraft Corporation, United Technologies Corporation, and Textron Inc. These OEMs may choose not to outsource production of aerostructures due to their own direct labor and overhead considerations and capacity utilization at their own facilities. Consequently, traditional factors affecting competition, such as price and quality of service, may not be significant determinants when OEMs decide whether to produce parts in-house or to outsource them. Offset requirements from customers of OEMs may also drive some decisions relative to their business model for production.

        Our principal competitors among non-OEM aerostructures suppliers are Aircelle S.A., Alenia Aeronautica, Fuji Heavy Industries, Ltd., GKN Aerospace, The Goodrich Corporation (expected to become a part of United Technologies Corporation, which has agreed to purchase The Goodrich Corporation), Kawasaki Heavy Industries, Inc., Mitsubishi Heavy Industries, Sonaca, Triumph Group, Inc., Latecoere S.A., Aerolia SAS, Premium Aerotech GmbH and Nexcelle. Our ability to compete for new aerostructures contracts depends upon (1) our design, engineering and manufacturing capabilities, (2) our underlying cost and pricing structure, (3) our business relationship with OEMs, and (4) our available manufacturing capacity. Some of our competitors have greater resources than we do and, therefore, may be able to adapt more quickly to new or emerging technologies and changes in customer requirements, or devote greater resources to the promotion and sale of their products than we can. Additionally, as part of its Power 8 restructuring plan, Airbus and its parent company EADS have formed wholly-owned French (Aerolia) and German (Premium Aerotech) subsidiaries for potential sale to third parties in 2012. If the facilities held by these subsidiaries are sold, or otherwise attempt to obtain work from third parties, the facilities could become competitors of Spirit. Providers of aerostructures have traditionally competed on the basis of cost, technology, quality and service. We believe that developing and maintaining a competitive advantage will require continued investment in product development, engineering, supply-chain management and sales and marketing, and we may not have enough resources to make such investments.

Employees

        As of December 31, 2011, we had approximately 13,791 employees and approximately 141 contract labor personnel, located in our four U.S. facilities. Approximately 82% of our U.S. employees are represented by five unions. Our largest union is the IAM, which represents approximately 6,312

22

Table of Contents

employees, or 46%, of the U.S. workforce. We successfully negotiated a new long-term ten-year contract with the IAM in 2010, which is in effect through June 25, 2020. The Society of Professional Engineering Employees in Aerospace — Wichita Technical and Professional Unit ("SPEEA — WTPU") represents approximately 2,288 employees, or 17%, of the U.S. workforce. In December of 2011, we successfully negotiated a new long-term 9¹/2 year contract with SPEEA-WTPU, which is in effect through January 31, 2021. The International Union, Automobile, Aerospace and Agricultural Implement Workers of America ("UAW") represents approximately 1,822 employees, or 12%, of the U.S. workforce. The UAW contract is in effect through November 30, 2020. The Society of Professional Engineering Employees in Aerospace — Wichita Engineering Unit ("SPEEA — WEU") represents approximately 752 employees, or 5%, of the U.S. workforce. We successfully negotiated a new contract with this union in 2009, which is in effect through December 1, 2012. The International Brotherhood of Electrical Workers, or IBEW, represents approximately 185 employees, or 1%, of the U.S. workforce. The IBEW contract is in effect through September 18, 2020.

        As of December 31, 2011, we had approximately 912 employees and approximately 92 contract labor personnel located in our two U.K. facilities. Approximately 661, or 73%, of our U.K. employees are represented by one union, Unite (Amicus Section). Currently, pay agreements with the Unite union are negotiated on an annual basis. Wages are typically the primary subject of our negotiations, while other contract terms generally remain the same from year to year until both parties agree to change them (either separately or in the aggregate). The pay agreement for the Unite union employees expires January 1, 2013. We are currently negotiating a new pay agreement with the manual workforce.

        As of December 31, 2011, we had approximately 415 employees and approximately 7 contract labor personnel in our Malaysia facility. None of our Malaysia employees are currently represented by a union.

        As of December 31, 2011, we had approximately 46 employees and approximately 16 contract labor personnel in our French facilities. None of our France employees are currently represented by a union.

        We consider our relationships with our employees to be satisfactory.

Government Contracts

        Companies engaged in supplying defense-related equipment and services to U.S. Government agencies, either directly or by subcontract, are subject to business risks specific to the defense industry. These risks include the ability of the U.S. Government to unilaterally: (1) suspend or debar us from receiving new prime contracts or subcontracts; (2) terminate existing contracts; (3) reduce the value of existing contracts; (4) audit our contract-related costs and fees, including allocated indirect costs; and (5) control and potentially prohibit the export of our products.

        Most U.S. Government contracts for which we subcontract can be terminated by the U.S. Government either for its convenience or if the prime contractor defaults by failing to perform under the contract. In addition, the prime contractor typically has the right to terminate our subcontract for its convenience or if we default by failing to perform under the subcontract. Termination for convenience provisions generally provide only for our recovery of costs incurred or committed, settlement expenses and profit on the work completed prior to termination. Termination for default provisions generally provide for the subcontractor to be liable for excess costs incurred by the prime contractor in procuring undelivered items from another source.

Foreign Ownership, Control or Influence ("FOCI")

        Due to the fact that more than 50% of our voting power is effectively controlled by a non-U.S. entity (Onex) we are required to operate in accordance with the terms and requirements of a Special Security Agreement, or SSA, with the Department of Defense ("DOD"). Under the DOD National Industrial Security Program Operating Manual ("NISPOM"), the U.S. Government will not award contracts to companies determined to be under FOCI, where a DoD Facility Security Clearance, or FCL, is required,

23

Table of Contents

unless certain "mitigation" measures are put in place. The purpose of the FOCI mitigation measures is to protect cleared U.S. defense contractors against improper FOCI.

        We have been cleared to the "Secret" level under an SSA, which is one of the recognized FOCI mitigation measures under the NISPOM. As a cleared entity, we must comply with the requirements of our SSA, the NISPOM and any other applicable U.S. Government industrial security regulations. Failure to follow the requirements of the SSA, the NISPOM or any other applicable U.S. Government industrial security regulations could, among other things, result in termination of our FCL, which in turn would preclude us from being awarded classified contracts or, under certain circumstances, performing on our existing classified contracts.

Governmental Regulations

        The commercial aircraft component industry is highly regulated by both the Federal Aviation Authority, or FAA, in the United States, the Joint Aviation Authority, or JAA, in Europe and other agencies throughout the world. The military aircraft component industry is governed by military quality specifications. We, and the components we manufacture, are required to be certified by one or more of these entities or agencies, and, in some cases, by individual OEMs, to engineer and service parts and components used in specific aircraft models.

        We must also satisfy the requirements of our customers, including OEMs and airlines that are subject to FAA regulations, and provide these customers with products and services that comply with the government regulations applicable to commercial flight operations. In addition, the FAA requires that various maintenance routines be performed on aircraft components. We believe that we currently satisfy or exceed these maintenance standards in our repair and overhaul services. We also maintain several FAA-approved repair stations.

        The technical data and components used in the design and production of our products, as well as many of the products and technical data we export, either as individual items or as components incorporated into aircraft, are subject to compliance with U.S. export control laws. Collaborative agreements that we may have with foreign persons, including manufacturers or suppliers, are also subject to U.S. export control laws.

        Our operations are also subject to a variety of worker and community safety laws. The Occupational Safety and Health Act, or OSHA, mandates general requirements for safe workplaces for all employees. In addition, OSHA provides special procedures and measures for the handling of certain hazardous and toxic substances. Our management believes that our operations are in material compliance with OSHA's health and safety requirements.

Item 1A.    Risk Factors

        An investment in our securities involves risk and uncertainties. The risks and uncertainties set forth below are those that we currently believe may materially and adversely affect us, our future business or results of operations, or investments in our securities. Additional risks and uncertainties that we are unaware of or that we currently deem immaterial may also materially and adversely affect us, our future business or results of operations or investments in our securities.

Risk Factors Related to Our Business and Industry

     Our commercial business is cyclical and sensitive to commercial airlines' profitability. The business of commercial airlines is, in turn, affected by global economic conditions and geo-political considerations.

        We compete in the aerostructures segment of the aerospace industry. Our customers' business, and therefore our own, is directly affected by the financial condition of commercial airlines and other economic factors, including global economic conditions and geo-political considerations that affect the demand for air transportation. Specifically, our commercial business is dependent on the demand from passenger airlines and cargo carriers for the production of new aircraft. Accordingly, demand for our commercial products is tied to the worldwide airline industry's ability to finance the purchase of new aircraft and the industry's forecasted demand for seats, flights, routes and cargo capacity. Similarly, the size and age of the worldwide commercial aircraft fleet affects the demand for new aircraft and, consequently, for our products. Such factors, in conjunction with evolving economic conditions, cause the market in which we operate to be cyclical to varying degrees, thereby affecting our business and operating results.

        The commercial airline industry is impacted by the strength of the global economy and the geopolitical events around the world. Near-term challenges include the risk of our customers' exposure to sovereign debt default, economic weakness in the airline industry, and the continuing volatility in global credit markets (which contributed to widespread economic slowdown, restricted discretionary spending, inability to finance airplane purchases, and a slowdown in air traffic). Possible exogenous shocks such as expanding conflicts or political unrest in the Middle East or Asia, renewed terrorist attacks against the industry, or pandemic health crises have the potential to cause precipitous declines in air traffic. Any protracted economic slump, continued adverse credit market conditions, future terrorist attacks, war or health concerns could cause airlines to cancel or delay the purchase of additional new aircraft which could result in a deterioration of commercial airplane backlogs. If demand for new aircraft decreases, there would likely be a decrease in demand for our commercial aircraft products, and our business, financial condition and results of operations could be materially adversely affected.

     Our business could be materially adversely affected if one of our components causes an aircraft accident.

        Our operations expose us to potential liabilities for personal injury or death as a result of the failure of an aircraft component that has been designed, manufactured or serviced by us or our suppliers. While we believe that our liability insurance coverage is sufficient to protect us in the event of future product liability claims, it may not be adequate. Also, we may not be able to maintain insurance coverage in the future at an acceptable cost. Any such liability not covered by insurance or for which third-party indemnification is not available could require us to dedicate a substantial portion of our cash flows to make payments on such liability, which could have a material adverse effect on our business, financial condition and results of operations.

        An accident caused by one of our components could also damage our reputation for quality products. We believe our customers consider safety and reliability as key criteria in selecting a provider of aerostructures. If an accident were to be caused by one of our components, or if we were to otherwise fail to maintain a satisfactory record of safety and reliability, our ability to retain and attract customers could be materially adversely affected.

     Our business could be materially adversely affected by product warranty obligations.

        Our operations expose us to potential liability for warranty claims made by customers or third parties with respect to aircraft components that have been designed, manufactured, or serviced by us or our suppliers. Material product warranty obligations could have a material adverse effect on our business, financial condition and results of operations.

     Because we depend on Boeing and, to a lesser extent, Airbus, as our largest customers, our sales, cash flows from operations and results of operations will be negatively affected if either Boeing or Airbus reduces the number of products it purchases from us or if either experiences business difficulties.

        Currently, Boeing is our largest customer and Airbus is our second-largest customer. For the twelve months ended December 31, 2011, approximately 85% and 10% of our net revenues were generated from sales to Boeing and Airbus, respectively. Although our strategy, in part, is to diversify our customer base by entering into supply arrangements with additional customers, we cannot give any assurance that we will be successful in doing so. Even if we are successful in obtaining and retaining new customers, we expect that Boeing and, to a lesser extent, Airbus, will continue to account for a substantial portion of our sales for the foreseeable future. Although we are a party to various supply contracts with Boeing and Airbus which obligate Boeing and Airbus to purchase all of their requirements for certain products from us, those agreements generally do not require specific minimum purchase volumes. In addition, if we breach certain obligations under these supply agreements and Boeing or Airbus exercises its right to terminate such agreements, our business will be materially adversely affected. Boeing and Airbus have the contractual right to cancel their supply agreements with us for convenience, which could include the termination of one or more aircraft models or programs for which we supply products. Although Boeing and Airbus would be required to reimburse us for certain expenses, there can be no assurance these payments would adequately cover our expenses or lost profits resulting from the termination. In addition, we have agreed to a limitation on recoverable damages if Boeing wrongfully terminates our main supply agreement with respect to any model or program. If this occurs, we may not be able to recover the full amount of our actual damages. Furthermore, if Boeing or Airbus (1) experiences a decrease in requirements for the products which we supply to it; (2) experiences a major disruption in its business, such as a strike, work stoppage or slowdown, a supply-chain problem or a decrease in orders from its customers; or (3) files for bankruptcy protection; our business, financial condition and results of operations could be materially adversely affected.

     Our largest customer, Boeing, operates in a very competitive business environment.

        Boeing operates in a highly competitive industry. Competition from Airbus, Boeing's main competitor, as well as from regional jet makers and other foreign manufacturers of commercial single-aisle aircraft, has intensified as these competitors expand aircraft model offerings and competitively price their products. As a result of this competitive environment, Boeing continues to face pressure on product offerings and sale prices. While we do have supply agreements with Airbus, we currently have substantially more business with Boeing and thus any adverse effect on Boeing's production of aircraft resulting from this competitive environment may have a material adverse effect on our business, financial condition and results of operations.

     Our business depends, in large part, on sales of components for a single aircraft program, the B737.

        For the twelve months ended December 31, 2011, approximately 47% of our net revenues were generated from sales of components to Boeing for the B737 aircraft. While we have entered into long-term supply agreements with Boeing to continue to provide components for the B737 for the life of the aircraft program, including commercial and the military P-8A Poseidon derivatives, Boeing does not have any obligation to purchase components from us for any replacement for the B737 that is not a commercial derivative model. Boeing has publicly announced its intention to replace the B737 with a next-generation single-aisle aircraft program named the Boeing 737 MAX, which will be a commercial derivative of the

26

Table of Contents

B737. However, if Boeing does not follow through on this announced intention and develops a next-generation program to replace the B737 which is not a commercial derivative, we may not have the next-generation technology, engineering and manufacturing capability necessary to obtain significant aerostructures supply business for such replacement program, may not be able to provide components for the replacement program at competitive prices or, for other reasons, may not be engaged by Boeing to the extent of our involvement in the B737 or at all. If we were unable to obtain significant aerostructures supply business for any B737 replacement program, our business, financial condition and results of operations could be materially adversely affected.

     Our business depends, in part, on the success of a new model aircraft, the B787.

        The success of our business will depend, in part, on the success of Boeing's new B787 program, for which we are a Tier I supplier. Following several announced delays, Boeing began commercial deliveries of the B787 in November 2011. Amounts capitalized into inventory represent our primary working capital exposure to the B787 delays. Given the break-even margins we currently project in our first contract accounting block, if Boeing is unable to meet currently anticipated production levels or if we are not able to achieve the cost reduction plan or successfully negotiate through the annual price adjustment, we could eventually need to recognize a forward-loss in our current contract accounting block. Any additional delays in the B787 program could further impact our cash flows from operations and could materially adversely affect our business, financial condition and results of operations.

     We may be required to repay Boeing up to approximately $629.1 million of advance payments related to the B787 Supply Agreement. The advances must be repaid in the event that Boeing does not take delivery of a sufficient number of ship sets prior to the termination of the aircraft program.

        In December 2010, Spirit and Boeing entered into a memorandum of agreement and a settlement agreement regarding certain claims associated with the development and production of the B787 airplane. As part of these agreements, Spirit received a payment in December, which was recorded as deferred revenue (short-term) within the consolidated balance sheet pending finalization of a contract amendment which would contain the final settlement terms.

        On May 12, 2011, Boeing and Spirit entered into the B787 Amendment, which finalized the provisions of the memorandum of agreement. Based on the terms of the B787 Amendment, the payment received by Spirit in December 2010 was reclassified from deferred revenue to revenue, and certain advance payments received by Spirit were also reclassified to revenue. The B787 Amendment also spread out repayment of a $700.0 million cash advance made by Boeing to Spirit in 2007 to be offset against the purchase price of the first 1,000 B787 ship sets delivered to Boeing, instead of the first 500 ship sets. In the event Boeing does not take delivery of 1,000 ship sets prior to the termination of the B787 program or the B787 Supply Agreement, any advances not then repaid will be applied against any outstanding payments then due by Boeing to us, and any remaining balance will be repaid in annual installments of $42.0 million on December 15th of each year until the advance payments have been fully recovered by Boeing.

        Accordingly, portions of the advance repayment liability are included as current and long-term liabilities in our consolidated balance sheet. As of December 31, 2011, the amount of advance payments and deferred revenue received by us from Boeing under the B787 Supply Agreement and not yet repaid or recognized as revenue was approximately $629.1 million.

     The profitability of certain development programs depends significantly on the assumptions surrounding satisfactory settlement of claims and assertions.

        For certain of our new development programs, we regularly commence work or incorporate customer requested changes prior to negotiating pricing terms for engineering work or the product which has been modified. We typically have the legal right to negotiate pricing for customer directed changes. In those cases, we assert to our customers our contractual rights to obtain the additional revenue or cost reimbursement we expect to receive upon finalizing pricing terms. An expected recovery value of these

27

---

Table of Contents

assertions is incorporated into our contract profitability estimates when applying contract accounting. Our inability to recover these expected values, among other factors, could result in the recognition of a forward-loss on these programs and could have a material adverse effect on our results of operations.

     We incur risk associated with new programs.

        New programs with new technologies typically carry risks associated with design responsibility, development of new production tools, hiring and training of qualified personnel, increased capital and funding commitments, ability to meet customer specifications, delivery schedules and unique contractual requirements, supplier performance, ability of the customer to meet its contractual obligations to us, and our ability to accurately estimate costs associated with such programs. In addition, any new aircraft program may not generate sufficient demand or may experience technological problems or significant delays in the regulatory certification or manufacturing and delivery schedule. If we were unable to perform our obligations under new programs to the customer's satisfaction or manufacture products at our estimated costs, if we were to experience unexpected fluctuations in raw material prices or supplier problems leading to cost overruns, if we were unable to successfully perform under revised design and manufacturing plans or successfully resolve claims and assertions, or if a new program in which we had made a significant investment was terminated or experienced weak demand, delays or technological problems, our business, financial condition and results of operations could be materially adversely affected. This risk includes the potential for default, quality problems, or inability to meet weight requirements and could result in low margin or forward-loss contracts, and the risk of having to write-off inventory if it were deemed to be unrecoverable over the life of the program. In addition, beginning new work on existing programs also carries risks associated with the transfer of technology, knowledge and tooling.

        In order to perform on new programs we may be required to construct or acquire new facilities requiring additional up-front investment costs. In the case of significant program delays and/or program cancellations, we could be required to bear certain unrecoverable construction and maintenance costs and incur potential impairment charges for the new facilities. Also, we may need to expend additional resources to determine an alternate revenue-generating use for the facilities. Likewise, significant delays in the construction or acquisition of a plant site could impact production schedules.

     Our operations depend on our ability to maintain continuing, uninterrupted production at our manufacturing facilities. Our production facilities are subject to physical and other risks that could disrupt production.

        Our manufacturing facilities could be damaged or disrupted by a natural disaster, war, terrorist activity or sustained mechanical failure. Although we have obtained property damage and business interruption insurance, a major catastrophe, such as a fire, flood, tornado or other natural disaster at any of our sites, war or terrorist activities in any of the areas where we conduct operations or the sustained mechanical failure of a key piece of equipment could result in a prolonged interruption of all or a substantial portion of our business. Any disruption resulting from these events could cause significant delays in shipments of products and the loss of sales and customers and we may not have insurance to adequately compensate us for any of these events. A large portion of our operations takes place at one facility in Wichita, Kansas and any significant damage or disruption to this facility in particular would materially adversely affect our ability to service our customers.

     Future commitments to our customers to increase production rates depend on our ability to expand production at our manufacturing facilities.

        Boeing and Airbus, our two largest customers, have both announced planned production rate increases for several of their major programs. In some cases, in order to meet these increases in production rates, we will need to make significant capital expenditures to expand our capacity and improve our performance. While some of these expenditures will be reimbursed by our customers, we could be required to bear a significant portion of the costs. In addition, the increases in production rates could cause disruptions in our manufacturing lines, which could materially adversely impact our ability to meet our

commitments to our customers, and have a resulting adverse effect on our financial condition and results of operations.

     We operate in a very competitive business environment.

        Competition in the aerostructures segment of the aerospace industry is intense. Although we have entered into supply agreements with Boeing and Airbus under which we are their exclusive supplier for certain aircraft parts, we will face substantial competition from both OEMs and non-OEM aerostructures suppliers in trying to expand our customer base and the types of parts we make.

        OEMs may choose not to outsource production of aerostructures due to, among other things, their own direct labor and other overhead considerations and capacity utilization at their own facilities. Consequently, traditional factors affecting competition, such as price and quality of service, may not be significant determinants when OEMs decide whether to produce a part in-house or to outsource.

        Our principal competitors among aerostructures suppliers are Aircelle S.A., Alenia Aeronautica, Fuji Heavy Industries, Ltd., GKN Aerospace, The Goodrich Corporation (expected to become a part of United Technologies Corporation, which has agreed to purchase The Goodrich Corporation), Kawasaki Heavy Industries, Inc., Mitsubishi Heavy Industries, Sonaca, Triumph Group, Inc., Latecoere S.A., Aerolia SAS, Premium Aerotech GmbH and Nexcelle. Some of our competitors have greater resources than we do and, therefore, may be able to adapt more quickly to new or emerging technologies and changes in customer requirements, or devote greater resources to the promotion and sale of their products than we can. Additionally, as part of its Power 8 restructuring plan, Airbus and its parent company EADS have formed wholly-owned French (Aerolia) and German (Premium Aerotech) subsidiaries for potential sale to third parties in 2012. If the facilities held by these subsidiaries are sold, or otherwise attempt to obtain work from third parties, the facilities could become competitors of Spirit. Providers of aerostructures have traditionally competed on the basis of cost, technology, quality and service. We believe that developing and maintaining a competitive advantage will require continued investment in product development, engineering, supply-chain management and sales and marketing, and we may not have enough resources to make such investments. For these reasons, we may not be able to compete successfully in this market or against our competitors, which could have a material adverse effect on our business, financial condition and results of operations.

     High switching costs may substantially limit our ability to obtain business that is currently under contract with other suppliers.

        Once a contract is awarded by an OEM to an aerostructures supplier, the OEM and the supplier are typically required to spend significant amounts of time and capital on design, manufacture, testing and certification of tooling and other equipment. For an OEM to change suppliers during the life of an aircraft program, further testing and certification would be necessary, and the OEM would be required either to move the tooling and equipment used by the existing supplier for performance under the existing contract, which may be expensive and difficult (or impossible), or to manufacture new tooling and equipment. Accordingly, any change of suppliers would likely result in production delays and additional costs to both the OEM and the new supplier. These high switching costs may make it more difficult for us to bid competitively against existing suppliers and less likely that an OEM will be willing to switch suppliers during the life of an aircraft program, which could materially adversely affect our ability to obtain new work on existing aircraft programs.

     Increases in labor costs, potential labor disputes and work stoppages at our facilities or the facilities of our suppliers or customers could materially adversely affect our financial performance.

        Our financial performance is affected by the availability of qualified personnel and the cost of labor. A majority of our workforce is represented by unions. If our workers were to engage in a strike, work stoppage or other slowdown, we could experience a significant disruption of our operations, which could cause us to be unable to deliver products to our customers on a timely basis and could result in a breach of

29

---

Table of Contents

our supply agreements. This could result in a loss of business and an increase in our operating expenses, which could have a material adverse effect on our business, financial condition and results of operations. In addition, our non-unionized labor force may become subject to labor union organizing efforts, which could cause us to incur additional labor costs and increase the related risks that we now face.

        We have agreed with Boeing to continue to operate substantial manufacturing operations in Wichita, Kansas until at least June 16, 2015 and we have other commitments to keep major programs in Wichita until 2020 in certain circumstances. This may prevent us from being able to offer our products at prices that are competitive in the marketplace and could have a material adverse effect on our ability to generate new business.

        In addition, many aircraft manufacturers, airlines and aerospace suppliers have unionized work forces. Any strikes, work stoppages or slowdowns experienced by aircraft manufacturers, airlines or aerospace suppliers could reduce our customers' demand for additional aircraft structures or prevent us from completing production of our aircraft structures.

        While over the past three years, we have successfully negotiated new contracts with four of the five unions that represent our U.S. employees, all of which are long-term ten-year agreements, our collective bargaining agreement with another union, which represents approximately 5% of our U.S. workforce, will expire in the fourth quarter of 2012. See "Business — Employees." We cannot give any assurance that we will be able to negotiate a new collective bargaining agreement with the remaining union, on commercially reasonable terms or at all. If we are unable to successfully negotiate a new collective bargaining agreement, or if we enter into a new collective bargaining agreement on terms which are less favorable to us than our existing agreement, our operating expenses could increase, which could have a material adverse effect on our business, financial condition and results of operations.

     Our business may be materially adversely affected if we lose our government, regulatory or industry approvals, if more stringent government regulations are enacted, or if industry oversight is increased.

        The FAA prescribes standards and qualification requirements for aerostructures, including virtually all commercial airline and general aviation products, and licenses component repair stations within the United States. Comparable agencies, such as the JAA in Europe, regulate these matters in other countries. If we fail to qualify for or obtain a required license for one of our products or services or lose a qualification or license previously granted, the sale of the subject product or service would be prohibited by law until such license is obtained or renewed and our business, financial condition and results of operations could be materially adversely affected. In addition, designing new products to meet existing regulatory requirements and retrofitting installed products to comply with new regulatory requirements can be expensive and time consuming.

        From time to time, the FAA, the JAA or comparable agencies propose new regulations or changes to existing regulations. These changes or new regulations generally increase the costs of compliance. To the extent the FAA, the JAA or comparable agencies implement regulatory changes, we may incur significant additional costs to achieve compliance.

        In addition, certain aircraft repair activities we intend to engage in may require the approval of the aircraft's OEM. Our inability to obtain OEM approval could materially restrict our ability to perform such aircraft repair activities.

     We are subject to regulation of our technical data and goods under U.S. export control laws.

        As a manufacturer and exporter of defense and dual-use technical data and commodities, we are subject to U.S. laws and regulations governing international trade and exports, including, but not limited to, the International Traffic in Arms Regulations, administered by the U.S. Department of State, and the Export Administration Regulations, administered by the U.S. Department of Commerce. Collaborative agreements that we may have with foreign persons, including manufacturers and suppliers, are also subject

30

---

Table of Contents

to U.S. export control laws. In addition, we are subject to trade sanctions against embargoed countries, administered by the Office of Foreign Assets Control within the U.S. Department of the Treasury.

        A determination that we have failed to comply with one or more of these export controls or trade sanctions could result in civil or criminal penalties, including the imposition of fines upon us as well as the denial of export privileges and debarment from participation in U.S. government contracts. Additionally, restrictions may be placed on the export of technical data and goods in the future as a result of changing geopolitical conditions. Any one or more of such sanctions could have a material adverse effect on our business, financial condition and results of operations.

     Our business is subject to regulation in the United States and internationally.

        The manufacturing of our products is subject to numerous federal, state and foreign governmental regulations. The number of laws and regulations that are being enacted or proposed by state, federal and international governments and authorities are increasing. Compliance with these regulations is difficult and expensive. If we fail to adhere, or are alleged to have failed to adhere, to any applicable federal, state or foreign laws or regulations, or if such laws or regulations negatively affect sales of our products, our business, prospects, results of operations, financial condition or cash flows may be adversely affected. In addition, our future results could be adversely affected by changes in applicable federal, state and foreign laws and regulations, or the interpretation or enforcement thereof, including those relating to manufacturing processes, product liability, trade rules and customs regulations, intellectual property, consumer laws, privacy laws, as well as accounting standards and taxation requirements (including tax-rate changes, new tax laws and revised tax law interpretations).

     We are subject to environmental, health and safety regulations and our ongoing operations may expose us to related liabilities.

        Our operations are subject to extensive regulation under environmental, health and safety laws and regulations in the United States and other countries in which we operate. We may be subject to potentially significant fines or penalties, including criminal sanctions, if we fail to comply with these requirements. We have made, and will continue to make, significant capital and other expenditures to comply with these laws and regulations. We cannot predict with certainty what environmental legislation will be enacted in the future or how existing laws will be administered or interpreted. Our operations involve the use of large amounts of hazardous substances and regulated materials and generate many types of wastes, including emissions of hexavalent chromium and volatile organic compounds, and so-called greenhouse gases such as carbon dioxide. Spills and releases of these materials may subject us to clean-up liability for remediation and claims of alleged personal injury, property damage and damage to natural resources, and we may become obligated to reduce our emissions of hexavalent chromium, volatile organic compounds and/or greenhouse gases. We cannot give any assurance that the aggregate amount of future remediation costs and other environmental liabilities will not be material.

        Boeing, our predecessor at the Wichita facility, is under an administrative consent order issued by the Kansas Department of Health and Environment to contain and remediate contaminated groundwater, which underlies a majority of our Wichita facility. Pursuant to this order and its agreements with us, Boeing has a long-term remediation plan in place, and treatment, containment and remediation efforts are underway. If Boeing does not comply with its obligations under the order and these agreements, we may be required to undertake such efforts and make material expenditures.

        In connection with the BAE Acquisition, we acquired a manufacturing facility in Prestwick, Scotland that is adjacent to contaminated property retained by BAE Systems. The contaminated property may be subject to a regulatory action requiring remediation of the land. It is also possible that the contamination may spread into the property we acquired. BAE Systems has agreed to indemnify us, subject to certain contractual limitations and conditions, for certain clean up costs and other losses, liabilities, expenses and claims related to existing pollution on the acquired property, existing pollution that migrates from the acquired property to a third party's property and any pollution that migrates to our property from property

31

Table of Contents

retained by BAE Systems. If BAE Systems does not comply with its obligations under the BAE Acquisition agreement, we may be required to undertake such efforts and make material expenditures.

        In the future, contamination may be discovered at or emanating from our facilities or at off-site locations where we send waste. The remediation of such newly discovered contamination, related claims for personal injury or damages, or the enactment of new laws or a stricter interpretation of existing laws, may require us to make additional expenditures, some of which could be material. See "Business — Environmental Matters".

     Significant consolidation in the aerospace industry could make it difficult for us to obtain new business.

        Suppliers in the aerospace industry have consolidated and formed alliances to broaden their product and integrated system offerings and achieve critical mass. This supplier consolidation is in part attributable to aircraft manufacturers more frequently awarding long-term sole-source or preferred supplier contracts to the most capable suppliers, thus reducing the total number of suppliers. If this consolidation were to continue, it may become more difficult for us to be successful in obtaining new customers.

     We may be materially adversely affected by high fuel prices.

        Due to the competitive nature of the airline industry, airlines are often unable to pass on increased fuel prices to customers by increasing fares. Fluctuations in the global supply of crude oil and the possibility of changes in government policy on jet fuel production, transportation and marketing make it difficult to predict the future availability of jet fuel. In the event there is an outbreak or escalation of hostilities or other conflicts, or significant disruptions in oil production or delivery in oil-producing areas or elsewhere, there could be reductions in the production or importation of crude oil and significant increases in the cost of fuel. If there were major reductions in the availability of jet fuel or significant increases in its cost, the airline industry and, as a result, our business, could be materially adversely affected.

     Interruptions in deliveries of components or raw materials, or increased prices for components or raw materials used in our products could delay production and/or materially adversely affect our financial performance, profitability, margins and revenues.

        We are highly dependent on the availability of essential materials and purchased components from our suppliers, some of which are available only from a sole source or limited sources. Our dependency upon regular deliveries from particular suppliers of components and raw materials means that interruptions or stoppages in such deliveries could materially adversely affect our operations until arrangements with alternate suppliers, to the extent alternate suppliers exist, could be made. If any of our suppliers were unable or were to refuse to deliver materials to us for an extended period of time, or if we were unable to negotiate acceptable terms for the supply of materials with these or alternative suppliers, our business could suffer.

        Moreover, we are dependent upon the ability of our suppliers to provide materials and components that meet specifications, quality standards and delivery schedules. Our suppliers' failure to provide expected raw materials or component parts that meet our technical specifications could adversely affect production schedules and contract profitability. We may not be able to find acceptable alternatives, and any such alternatives could result in increased costs for us and possible forward-losses on certain contracts. Even if acceptable alternatives are found, the process of locating and securing such alternatives might be disruptive to our business and might lead to termination of our supply agreements with our customers.

        Our continued supply of materials is subject to a number of risks including:

•

the destruction of or damage to our suppliers' facilities or their distribution infrastructure;



•

a work stoppage or strike by our suppliers' employees;



•

the failure of our suppliers to provide materials of the requisite quality or in compliance with specifications;

32

---

Table of Contents

•

the failure of essential equipment at our suppliers' plants;



•

the failure of our suppliers to satisfy U.S. and international import and export control laws for goods that we purchase from such suppliers;



•

the failure of our suppliers to meet regulatory standards;



•

the failure, shortage or delay in the delivery of raw materials to our suppliers;



•

contractual amendments and disputes with our suppliers; and



•

inability of our suppliers to perform as a result of the weakened global economy or otherwise.

        In addition, our profitability is affected by the prices of the components and raw materials, such as titanium, aluminum and carbon fiber, used in the manufacturing of our products. These prices may fluctuate based on a number of factors beyond our control, including world oil prices, changes in supply and demand, general economic conditions, labor costs, competition, import duties, tariffs, currency exchange rates and, in some cases, government regulation. Although our supply agreements with Boeing and Airbus allow us to pass on to our customers certain unusual increases in component and raw material costs in limited situations, we may not be fully compensated by the customers for the entirety of any such increased costs.

     Our business will suffer if certain key officers or employees discontinue employment with us or if we are unable to recruit and retain highly skilled staff.

        The success of our business is highly dependent upon the skills, experience and efforts of our President and Chief Executive Officer, Jeffrey Turner, and certain of our other key officers and employees. As the top executive officer of Boeing Wichita for almost ten years prior to the Boeing Acquisition, Mr. Turner gained extensive experience in running our business and long-standing relationships with many high-level executives at Boeing, our largest customer. We believe Mr. Turner's reputation in the aerospace industry and relationship with Boeing are critical elements in maintaining and expanding our business. The loss of Mr. Turner or other key personnel could have a material adverse effect on our business, operating results or financial condition. Our business also depends on our ability to continue to recruit, train and retain skilled employees, particularly skilled engineers. The market for these resources is highly competitive. We may be unsuccessful in attracting and retaining the engineers we need and, in such event, our business could be materially adversely affected. The loss of the services of any skilled key personnel, or our inability to hire new personnel with the requisite skills, could impair our ability to provide products to our customers or manage our business effectively.

     We are subject to the requirements of the National Industrial Security Program Operating Manual ("NISPOM") for our Facility Security Clearance ("FCL"), which is a prerequisite for our ability to perform on classified contracts for the U.S. Government.

        A Department of Defense ("DOD") FCL is required for a company to be awarded and perform on classified contracts for the DOD and certain other agencies of the U.S. Government. From time to time we have performed and may perform on classified contracts, although we did not generate any revenues from classified contracts for the twelve months ended December 31, 2011. We have obtained an FCL at the "Secret" level. Due to the fact that more than 50% of our voting power is effectively controlled by a non-U.S. entity (Onex), we are required to operate in accordance with the terms and requirements of our Special Security Agreement ("SSA") with the DOD. If we were to violate the terms and requirements of our SSA, the NISPOM, or any other applicable U.S. Government industrial security regulations, we could lose our FCL. We cannot give any assurance that we will be able to maintain our FCL. If for some reason our FCL is invalidated or terminated, we may not be able to continue to perform under our classified contracts in effect at that time, and we would not be able to enter into new classified contracts, which could adversely affect our revenues.

     We derive a significant portion of our net revenues from direct and indirect sales outside the United States and are subject to the risks of doing business in foreign countries.

        We derive a significant portion of our revenues from sales by Boeing and Airbus to customers outside the United States. In addition, for the twelve months ended December 31, 2011, direct sales to our non-U.S. customers accounted for approximately 13% of our net revenues. We expect that our and our customers' international sales will continue to account for a significant portion of our net revenues for the foreseeable future. As a result, we are subject to risks of doing business internationally, including:

•

changes in regulatory requirements;



•

domestic and foreign government policies, including requirements to expend a portion of program funds locally and governmental industrial cooperation requirements;



•

fluctuations in foreign currency exchange rates;



•

the complexity and necessity of using foreign representatives and consultants;



•

uncertainties and restrictions concerning the availability of funding credit or guarantees;



•

imposition of tariffs and embargos, export controls and other trade restrictions;



•

the difficulty of management and operation of an enterprise spread over various countries;



•

compliance with a variety of foreign laws, as well as U.S. laws affecting the activities of U.S. companies abroad, including the Foreign Corrupt Practices Act, the U.K. Bribery Act and other applicable anti-bribery laws; and



•

economic and geopolitical developments and conditions, including international hostilities, acts of terrorism and governmental reactions, inflation, trade relationships and military and political alliances.

        While these factors and the effect of these factors are difficult to predict, adverse developments in one or more of these areas could materially adversely affect our business, financial condition and results of operations in the future.

     Our fixed-price contracts and requirements to re-negotiate pricing at specified times may commit us to unfavorable terms.

        We provide most of our products and services through long-term contracts in which the pricing terms are fixed based on certain production volumes. Accordingly, we bear the risk that we will not be able to sustain a cost structure that is consistent with assumptions used in bidding on contracts. Increased or unexpected costs may reduce our profit margins or cause us to sustain losses on these contracts. Other than certain increases in raw material costs which can be passed on to our customers, we must fully absorb cost overruns, notwithstanding the difficulty of estimating all of the costs we will incur in performing these contracts and in projecting the ultimate level of sales that we may achieve. Our failure to anticipate technical problems, estimate delivery reductions, estimate costs accurately or control costs during performance of a fixed-price contract may reduce the profitability of a contract or cause a loss.

        This risk particularly applies to products such as the Boeing B787, for which we had delivered fifty-six production articles as of December 31, 2011 since the inception of the program, and in respect of which our profitability at the contracted price depends on our being able to achieve production cost reductions as we gain production experience. Pricing for the initial configuration of the B787-8, the base model currently in production, is generally established through 2021, with prices decreasing as cumulative volume levels are achieved. Prices are subject to adjustment for abnormal inflation (above a specified level in any year) and for certain production, schedule and other specific changes. When we negotiated the B787-8 pricing, we assumed that favorable trends in volume, learning curve efficiencies and future pricing from suppliers would reduce our production costs over the life of the B787 program, thus maintaining or improving our margin on each B787 we produced. We cannot give any assurance that our development of new

34

---

Table of Contents

technologies or capabilities will be successful or that we will be able to reduce our B787 production costs over the life of the program. Our failure to reduce production costs as we have anticipated could result in decreasing margin on the B787 during the life of the program and the need to record a forward-loss for the current contract accounting block.

        Many of our other production cost estimates also contain pricing terms which anticipate cost reductions over time. In addition, although we have entered into these fixed price contracts with our customers, they may nonetheless seek to re-negotiate pricing with us in the future. Any such higher costs or re-negotiations could materially adversely affect our profitability, margins and revenues.

        Certain of our long-term supply agreements provide for re-negotiation of established pricing terms at specified times. In particular, pricing terms under our supply agreement with Boeing for the B737, B747, B767 and B777 platforms, which accounted for 71% of our net revenues in 2011, expire in May 2013. Due to the approaching expiration of the established pricing terms, we are in the initial stages of re-negotiating pricing with Boeing for a period to be agreed upon by the parties. We are required to negotiate the pricing for such additional period in good faith based on then-prevailing U.S. market conditions for forward fuselages, B737 fuselages and B737/B777 struts and nacelles and based on then-prevailing global market conditions for all other products. If we are unable to agree upon pricing, then, until such dispute is resolved, pricing will be determined according to the existing prices, adjusted using a quantity-based price adjustment formula and specified annual escalation until such time as future pricing is agreed. If we agree on future pricing that provides us with operating margins that are lower than those which we currently experience, or if we are unable to agree on new pricing terms and the default pricing terms remain in effect for a period of time, our business, financial condition and results of operations could be materially adversely affected.

     We face a class-action lawsuit, which could potentially result in substantial costs, diversion of management's attention and resources, and negative publicity.

        A lawsuit has been filed against Spirit, Onex, and Boeing alleging age discrimination in the hiring of employees by Spirit when Boeing sold Boeing Wichita to Onex. The complaint was filed in U.S. District Court in Wichita, Kansas and seeks class-action status, an unspecified amount of compensatory damages and more than $1.5 billion in punitive damages. On June 30, 2010, the U.S. District Court granted defendants' dispositive motions, finding that the case should not be allowed to proceed as a class action. The plaintiffs have appealed the district court's decision to the United States Court of Appeals for the Tenth Circuit, which could reverse the District Court's June 30 ruling. The asset purchase agreement between Onex and Boeing relating to the Boeing Acquisition requires Spirit to indemnify Boeing for its damages resulting from the employment decisions that were made by us with respect to former employees of Boeing Wichita which relate or allegedly relate to the involvement of, or consultation, with employees of Boeing in such employment decisions. The lawsuit could result in substantial costs, divert management's attention and resources from our operations and negatively affect our public image and reputation. An unfavorable outcome or prolonged litigation related to these matters could materially harm our business.

     If we are unable to protect our information technology infrastructure against service interruptions, data corruption, cyber-based attacks or network security breaches, our operations could be disrupted.

        We rely on information technology networks and systems to manage and support a variety of business activities, including procurement and supply chain, engineering support, and manufacturing. Our information technology systems, some of which are managed by third-parties, may be susceptible to damage, disruptions or shutdowns due to failures during the process of upgrading or replacing software, databases or components thereof, power outages, hardware failures, computer viruses, attacks by computer hackers, 12 telecommunication failures, user errors or catastrophic events. In addition, security breaches could result in unauthorized disclosure of confidential information. If our information technology systems suffer severe damage, disruption or shutdown and our business continuity plans do not effectively resolve

35

---

Table of Contents

the issues in a timely manner, our manufacturing process could be disrupted resulting in late deliveries or even no deliveries if there is a total shutdown.

     We are implementing new company-wide software systems, which could increase our information technology expenditures and cause unexpected production delays.

        We have recently implemented an Enterprise Resource Planning ("ERP") software system in several of our facilities, and have begun implementation of other system upgrades and infrastructure changes. We plan to implement the ERP software in all of our primary facilities over the next twenty-four months. Our total expenditures for these systems and upgrades could exceed the planned budget. In addition, unexpected problems with the implementation could result in production or other delays.

     We do not own most of the intellectual property and tooling used in our business.

        Our business depends on using certain intellectual property and tooling that we have rights to use under license grants from Boeing. These licenses contain restrictions on our use of Boeing intellectual property and tooling and may be terminated if we default under certain of these restrictions. Our loss of license rights to use Boeing intellectual property or tooling would materially adversely affect our business. See "Business — Our Relationship with Boeing — License of Intellectual Property." In addition to the licenses with Boeing, we license some of the intellectual property needed for performance under some of our supply contracts from our customers under those supply agreements. We must honor our contractual commitments to our customers related to intellectual property and comply with infringement laws governing our use of intellectual property. In the event we obtain new business from new or existing customers, we will need to pay particular attention to these contractual commitments and any other restrictions on our use of intellectual property to make sure that we will not be using intellectual property improperly in the performance of such new business. In the event we use any such intellectual property improperly, we could be subject to an infringement claim by the owner or licensee of such intellectual property.

        In the future, our entry into new markets may require obtaining additional license grants from Boeing and/or from other third parties. If we are unable to negotiate additional license rights on acceptable terms (or at all) from Boeing and/or other third parties as the need arises, our ability to enter new markets may be materially restricted. In addition, we may be subject to restrictions in future licenses granted to us that may materially restrict our use of third party intellectual property.

     Our success depends in part on the success of our research and development initiatives.

        We spent approximately $35.7 million on research and development during the twelve months ended December 31, 2011. Our expenditures on our research and development efforts may not create any new sales opportunities or increases in productivity that are commensurate with the level of resources invested.

        We are in the process of developing specific technologies and capabilities in pursuit of new business and in anticipation of customers going forward with new programs. If any such programs do not go forward or are not successful, we may be unable to recover the costs incurred in anticipation of such programs and our profitability and revenues may be materially adversely affected.

     Any future business combinations, acquisitions, mergers, or joint ventures will expose us to risks, including the risk that we may not be able to successfully integrate these businesses or achieve expected operating synergies.

        We actively consider strategic transactions from time to time. We evaluate acquisitions, joint ventures, alliances and co-production programs as opportunities arise, and we may be engaged in varying levels of negotiations with potential competitors at any time. We may not be able to effect transactions with strategic alliance, acquisition or co-production program candidates on commercially reasonable terms or at all. If we enter into these transactions, we also may not realize the benefits we anticipate. In addition, we

36

---

Table of Contents

may not be able to obtain additional financing for these transactions. The integration of companies that have previously been operated separately involves a number of risks, including, but not limited to:

•

demands on management related to the increase in size after the transaction;



•

the diversion of management's attention from the management of daily operations to the integration of operations;



•

difficulties in the assimilation and retention of employees;



•

difficulties in the assimilation of different cultures and practices, as well as in the assimilation of geographically dispersed operations and personnel, who may speak different languages;



•

difficulties combining operations that use different currencies or operate under different legal structures;



•

difficulties in the integration of departments, systems (including accounting systems), technologies, books and records and procedures, as well as in maintaining uniform standards, controls (including internal accounting controls), procedures and policies;



•

compliance with the Foreign Corrupt Practices Act, the U.K. Bribery Act and other applicable anti-bribery laws; and



•

constraints (contractual or otherwise) limiting our ability to consolidate, rationalize and/or leverage supplier arrangements to achieve integration.

        Consummating any acquisitions, joint ventures, alliances or co-production programs could result in the incurrence of additional debt and related interest expense, as well as unforeseen contingent liabilities.

     We could be required to make future contributions to our defined benefit pension and post-retirement benefit plans as a result of adverse changes in interest rates and the capital markets.

        Our estimates of liabilities and expenses for pensions and other post-retirement benefits incorporate significant assumptions including the rate used to discount the future estimated liability, the long-term rate of return on plan assets and several assumptions relating to the employee workforce (salary increases, medical costs, retirement age and mortality). A dramatic decrease in the fair value of our plan assets resulting from movements in the financial markets may cause the status of our plans to go from an over-funded status to an under-funded status and result in cash funding requirements to meet any minimum required funding levels. Our results of operations, liquidity, or shareholders' equity in a particular period could be affected by a decline in the rate of return on plan assets, the rate used to discount the future estimated liability, or changes in employee workforce assumptions.

Risk Factors Related to Our Capital Structure

     The interests of our controlling stockholder may conflict with your interests.

        Onex Partners LP, Onex Corporation and their respective partners and affiliates that beneficially own our class B common stock, herein referred to collectively as the "Onex entities", own 22,411,638 shares of our class B common stock. Our class A common stock has one vote per share, while our class B common stock has ten votes per share on all matters to be voted on by our stockholders. Consequently, the Onex entities control approximately 62% of the combined voting power of our outstanding common stock. Accordingly, and for so long as the Onex entities continue to hold class B common stock that represents at least 10% of the total number of shares of common stock outstanding, Onex will exercise a controlling influence over our business and affairs and will have the power to determine all matters submitted to a vote of our stockholders, including the election of directors and approval of significant corporate transactions such as amendments to our certificate of incorporation, mergers and the sale of all or substantially all of our assets. Onex could cause corporate actions to be taken even if the interests of Onex conflict with the interests of our other stockholders. This concentration of voting power could have the

Table of Contents

effect of deterring or preventing a change in control of Spirit that might otherwise be beneficial to our stockholders. Gerald W.

     Our substantial debt could adversely affect our financial condition and our ability to operate our business. The terms of the indenture governing our long-term bonds and our senior secured credit facility impose significant operating and financial restrictions on our company and our subsidiaries, which could also adversely affect our operating flexibility and put us at a competitive disadvantage by preventing us from capitalizing on business opportunities.

        As of December 31, 2011, we had total debt of approximately $1,200.9 million, including approximately $561.9 million of borrowings under our senior secured credit facility, $594.9 million of long-term bonds, a $16.1 million Malaysian loan, approximately $15.2 million of capital lease obligations, and $12.8 million in other debt obligations. In addition to our debt, as of December 31, 2011, we had $46.5 million of letters of credit and letters of guarantee outstanding.

        The terms of the indentures governing our long-term bonds and our senior secured credit facility impose significant operating and financial restrictions on us, which limit our ability, among other things, to:

•

incur additional debt or issue preferred stock;



•

pay dividends or make distributions to our stockholders;



•

repurchase or redeem our capital stock;



•

make investments;



•

incur liens without granting equal and ratable liens to the holders of the notes;



•

enter into transactions with our stockholders and affiliates;



•

sell certain assets;



•

acquire the assets of, or merge or consolidate with, other companies; and



•

incur restrictions on the ability of our subsidiaries to make distributions or transfer assets to us.

        These restrictions could have consequences, including the following:

•

making it more difficult for us to satisfy our obligations with respect to our debt;



•

limiting our ability to obtain additional financing to fund future working capital, capital expenditures, strategic acquisitions or other general corporate requirements;



•

requiring a substantial portion of our cash flows to be dedicated to debt service payments instead of other purposes;



•

increasing our vulnerability to general adverse economic and industry conditions;



•

limiting our financial flexibility in planning for and reacting to changes in the industry in which we compete;



•

placing us at a disadvantage compared to other, less leveraged competitors;



•

having a material adverse effect on us if we fail to comply with the covenants in the senior secured credit facility or in the indentures governing our long-term bonds or in the instruments governing our other debt; and



•

increasing our cost of borrowing.

        Our existing senior secured revolving credit facility, which matures on September 30, 2014, is a significant source of liquidity for our business. The failure to extend or renew this agreement could have a

significant effect on our ability to invest sufficiently in our programs, fund day to day operations, or pursue strategic opportunities.

        We cannot assure you that we will be able to maintain compliance with the covenants in the agreements governing our indebtedness in the future or, if we fail to do so, that we will be able to obtain waivers from the lenders and/or amend the covenants.

        In addition, despite the restrictions and limitations described above, subject to the limits contained in the agreements governing our indebtedness, we may be able to incur additional debt from time to time to finance working capital, capital expenditures, investments or acquisitions, or for other purposes. The terms of any future indebtedness we may incur could include more restrictive covenants. If we incur additional debt, the risks related to our high level of debt could intensify.

        In addition, if we are unable to generate sufficient cash flow to service our debt and meet our other commitments, we may need to refinance all or a portion of our debt, sell material assets or operations, or raise additional debt or equity capital. We cannot provide assurance that we could effect any of these actions on a timely basis, on commercially reasonable terms or at all, or that these actions would be sufficient to meet our capital requirements. In addition, the terms of our existing or future debt agreements may restrict us from effecting certain or any of these alternatives.

        Global credit markets are still recovering from the 2008 financial crisis, and are subject to numerous risk factors, including but not limited to concerns over sovereign debt in Europe and elsewhere; the impact and effectiveness of new financial legislation and regulation in the United States and Europe; the impact of those reforms on borrowers, financial institutions and credit rating agencies; potential systemic risk resulting from the interrelationship of credit market products and participants; global governmental and central banking policies; and conflict and political instability in the Middle East and Asia. There can be no assurance that access to credit markets will continue to be available to us.

     Any reduction in our credit ratings could materially and adversely affect our business or financial condition.

        As of December 31, 2011, our corporate credit rating at Standard & Poor's Rating Services remained unchanged at BB and our corporate credit rating at Moody's Investor Services remained unchanged at Ba2.

        The ratings reflect the agencies' assessment of our ability to pay interest and principal on our debt securities and credit agreements. A rating is not a recommendation to purchase, sell or hold securities. Each rating is subject to revision or withdrawal at any time by the assigning rating organization. Each rating agency has its own methodology for assigning ratings and, accordingly, each rating should be considered independently of all other ratings. Lower ratings would typically result in higher interest costs of debt securities when they are sold, and could make it more difficult to issue future debt securities. In addition, a downgrade in our fixed or revolving long-term debt rating could result in an increase in borrowing costs under our senior secured credit facility. Any downgrade in our credit ratings could thus have a material adverse effect on our business or financial condition.

     We may sell more equity and reduce your ownership in Spirit Holdings.

        Our business plan may require the investment of new capital, which we may raise by issuing additional equity (including equity interests which may have a preference over shares of our class A common stock) or additional debt (including debt securities and/or bank loans). However, this capital may not be available at all, or when needed, or upon terms and conditions favorable to us. The issuance of additional equity in Spirit Holdings may result in significant dilution of shares of our class A common stock. We may issue additional equity in connection with or to finance acquisitions. Further, our subsidiaries could issue securities in the future to persons or entities (including our affiliates) other than us or another subsidiary. This could materially adversely affect your investment in us because it would dilute your indirect ownership interest in our subsidiaries.

     Spirit Holdings' certificate of incorporation and by-laws and our supply agreements with Boeing contain provisions that could discourage another company from acquiring us and may prevent attempts by our stockholders to replace or remove our current management.

        Provisions of Spirit Holdings' certificate of incorporation and by-laws may discourage, delay or prevent a merger or acquisition that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or remove our current board of directors. These provisions include:

•

multi-vote shares of common stock, which are owned by the Onex entities and management stockholders;



•

advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on by stockholders at stockholder meetings; and



•

the authority of the board of directors to issue, without stockholder approval, up to 10 million shares of preferred stock with such terms as the board of directors may determine and an additional 56,520,263 shares of class A common stock (net of shares issued but subject to vesting requirements under our benefit plans and shares reserved for issuance upon conversion of outstanding shares of class B common stock) and an additional 125,081,189 shares of class B common stock (net of shares issued but subject to vesting requirements under our benefit plans).

        In addition, our supply agreements with Boeing include provisions giving Boeing the ability to terminate the agreements in the event any of certain disqualified persons acquire a majority of Spirit's direct or indirect voting power or all or substantially all of Spirit's assets. See "Business — Our Relationship with Boeing."

     Spirit Holdings is a "controlled company" within the meaning of the New York Stock Exchange rules and, as a result, qualifies for, and relies on, exemptions from certain corporate governance requirements.

        Because the Onex entities own more than 50% of the combined voting power of the common stock of Spirit Holdings, Spirit Holdings is deemed a "controlled company" under the rules of the New York Stock Exchange, or NYSE. As a result, Spirit Holdings qualifies for, and relies upon, the "controlled company" exception to the board of directors and committee composition requirements under the rules of the NYSE. Pursuant to this exception, Spirit Holdings is exempt from rules that would otherwise require that Spirit Holdings' board of directors be comprised of a majority of "independent directors" (as defined under the rules of the NYSE), and that Spirit Holdings' compensation committee and corporate governance and nominating committee be comprised solely of "independent directors," so long as the Onex entities continue to own more than 50% of the combined voting power of the common stock of Spirit Holdings. Spirit Holdings' board of directors consists of nine directors, five of whom qualify as "independent." Spirit Holdings' compensation and corporate governance and nominating committees are not comprised solely of "independent directors." Spirit Holdings does not currently rely on the exemption related to board composition, although it may do so in the future. See "Management — Executive Officers and Directors" and "Committees of the Board of Directors."

     Our stock price may be volatile.

        Price fluctuations in our class A common stock could result from general market and economic conditions and a variety of other factors, including:

•

actual or anticipated fluctuations in our operating results;



•

changes in aerostructures pricing;

•

our competitors' and customers' announcements of significant contracts, acquisitions or strategic investments;



•

changes in our growth rates or our competitors' and customers' growth rates;



•

the timing or results of regulatory submissions or actions with respect to our business;



•

our inability to finance or raise additional capital;



•

conditions of the aerostructure industry, in the financial markets, or economic conditions in general; and



•

        The Malaysian manufacturing plant is located at the Malaysia International Aerospace Center (MIAC) in Subang. The 269,000 square foot leased facility is set on 45 acres and is centrally located with easy access to Kuala Lumpur, Malaysia's capital city, as well as nearby ports and airports. The facility assembles composite panels for wing components. An additional 65,000 square foot warehouse will be constructed in 2012 for shipping/receiving and parts storage to make room for additional manufacturing space in the existing building.

        The Wichita and Tulsa manufacturing facilities have significant scale to accommodate the very large structures that are manufactured there, including, in Wichita, entire fuselages. Three of the U.S. facilities are in close proximity, with approximately 175 miles between Wichita and Tulsa and 90 miles between Tulsa and McAlester. Currently, these U.S. facilities utilize approximately 95% of the available building space. The Prestwick manufacturing facility currently utilizes only 63% of the space; of the remaining space, 21% is leased and 16% is vacant. The Preston office space is located in North Lancashire, England, approximately 200 miles south of Prestwick.

        The Kinston, North Carolina facility, which supports the manufacturing of composite panels and wing components, was completed in 2010. The site rests on 304 acres and totals 766,000 square feet. In addition to the primary manufacturing facility, three additional buildings are leased from the Global Transpark Authority. A 27,700 square foot office/warehouse supports receiving needs, a 26,400 square foot building provides tooling storage, and a 121,000 square foot manufacturing facility supports light manufacturing.

        The Saint-Nazaire, France site, which opened in July 2010, was built on 6.25 acres and totals 58,800 square feet. This facility receives center fuselage frame sections for the Airbus A350 XWB from the facility in Kinston, North Carolina. Sections designed and manufactured in North Carolina are shipped across the Atlantic, received in Saint-Nazaire, and assembled before being transported to Airbus. Operations in this facility commenced in early 2011, with first deliveries occurring later in the year. Additionally, a 3,400 square foot office area in Toulouse, France has been leased since August 2009 for engineering support.

Item 5.    Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

        Our class A common stock has been quoted on the NYSE under the symbol "SPR" since November 21, 2006. Prior to that time, there was no public market for our stock. As of February 17, 2012, there were approximately 411 holders of record of class A common stock. However, we believe that many additional holders of our class A common stock are unidentified because a substantial number of shares are held of record by brokers or dealers for their customers in street names. The closing price on February 17, 2012 was $23.84 per share as reported by the NYSE.

        As of February 17, 2012, there were approximately 136 holders of record of class B common stock. Our class B common stock is neither listed nor publicly traded.

        We did not pay any cash dividends in 2010 or 2011 and we currently do not intend to pay cash dividends and, under conditions in which our cash is below specific levels, we are prohibited from doing so under credit agreements governing our credit facilities. Our future dividend policy will depend on the requirements of financing agreements to which we may be a party. Any future determination to pay dividends will be at the discretion of our Board of Directors and will depend upon, among other factors, our results of operations, financial condition, capital requirements and contractual restrictions.

Item 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations

        You should read the following discussion of our financial condition and results of operations in conjunction with the audited consolidated financial statements, the notes to the audited consolidated financial statements and the "Selected Consolidated Financial Information and Other Data" appearing elsewhere in this Annual Report. This section includes "forward-looking statements." Forward-looking statements generally can be identified by the use of forward-looking terminology such as "may," "will," "should," "expect," "anticipate," "intend," "estimate," "believe," "project," "continue," "plan," "forecast," or other similar words. These statements reflect management's current views with respect to future events and are subject to risks and uncertainties, both known and unknown, including, but not limited to, those described in the "Risk Factors" section of this Annual Report. See also "Cautionary Statement Regarding Forward-Looking Statements." Our actual results may vary materially from those anticipated in forward-looking statements. We caution investors not to place undue reliance on any forward-looking statements.

Recent Events

        On November 29, 2011, AMR Corporation, the parent company of American Airlines, filed for Chapter 11 bankruptcy protection. The airline announced that it and its regional affiliate American Eagle would continue to operate as usual, fly their normal schedules, honor reservations and make exchanges and refunds. We have outstanding receivables for spare parts owed by American Airlines, for which we have adequately reserved.

        In December of 2011, we completed negotiations with employees represented by the SPEEA-WTPU. The new contract that was ratified in December of 2011 is in effect until January 31, 2021. SPEEA represents about 2,300 of our professional and technical non-engineering employees in Wichita.

        On January 9, 2012, we successfully delivered the first composite center fuselage section for the Airbus A350 XWB program. The upper and lower shell (section 15) composite fuselage panels were joined in our Saint-Nazaire, France, facility before being delivered to Airbus.

        On January 9, 2012, we drew down $100.0 million from our revolving credit facility to fund short-term working capital needs. Historically, cyclical cash flows dictate lower cash balances during the first quarter of the year.

        On February 13, 2012, the Society of Professional Engineering Employees in Aerospace (SPEEA) filed two identical unfair labor practice (ULP) charges against the Company, one on behalf of each of the two bargaining units it represents, the Wichita Engineering Unit (WEU) and the Wichita Technical and Professionals Unit (WTPU). The ULPs claim that the Company has modified working conditions related to a performance improvement process without negotiating with SPEEA. SPEEA represents approximately 752 employees in the Wichita Engineering Unit and approximately 2,288 employees in the Wichita Technical and Professional Unit. The Company intends to vigorously defend its position and is evaluating the impact to its financial position, results of operations and liquidity position resulting from this matter.

Overview

        We are one of the largest independent non-OEM (original equipment manufacturer) aircraft parts designers and manufacturers of commercial aerostructures in the world, based on annual revenues, as well as the largest independent supplier of aerostructures to Boeing. In addition, we are one of the largest independent suppliers of aerostructures to Airbus. Boeing and Airbus are the two largest aircraft OEMs in the world. Aerostructures are structural components, such as fuselages, propulsion systems and wing systems for commercial and military aircraft. For the twelve months ended December 31, 2011, we generated net revenues of $4,863.8 million and net income of $192.4 million.

        We are organized into three principal reporting segments: (1) Fuselage Systems, which includes forward, mid and rear fuselage sections, (2) Propulsion Systems, which includes nacelles, struts/pylons and engine structural components, and (3) Wing Systems, which includes wings, wing components, flight control surfaces and other miscellaneous structural parts. All other activities fall within the All Other

segment, principally made up of sundry sales of miscellaneous services, tooling contracts, and sales of natural gas through a tenancy-in-common with other companies that have operations in Wichita, Kansas. The Fuselage Systems segment manufactures products at our facilities in Wichita, Kansas and Kinston, North Carolina, with an assembly plant in Saint-Nazaire, France for the A350 XWB program. The Propulsion Systems segment manufactures products at our facilities in Wichita, Kansas. The Wing Systems segment manufactures products at our facilities in Tulsa and McAlester, Oklahoma; Prestwick, Scotland; Subang, Malaysia and Kinston, North Carolina. Fuselage Systems, Propulsion Systems, Wing Systems and All Other represented approximately 50%, 25%, 25% and less than 1%, respectively, of our net revenues for the twelve months ended December 31, 2011.

Market Trends

        The financial health of the commercial airline industry has a direct and significant effect on our commercial aircraft programs. The global industry's revenue rebounded sharply in 2010 for both passenger air traffic and cargo freight, after significant contraction in 2008 and 2009. One key near-term variable affecting the industry is fuel costs. If fuel costs were to rise near the recent highs of 2008, airlines might respond with canceled or deferred orders. However, Boeing and Airbus have indicated that they do not anticipate any near-term erosion to their backlogs. Both OEM's have announced multiple production rate increases, which commenced in 2011 with the respective single-aisle programs (Airbus A320 and Boeing B737).

        Demand for commercial aerostructures is highly correlated to demand for new aircraft. From 2005 through 2008, Boeing and Airbus experienced an unprecedented order intake and backlog growth. In that period, the two manufacturers obtained combined total gross orders of approximately 8,400 aircraft. Their aggregate backlog increased from nearly 2,600 to over 7,400 aircraft. An order slowdown in 2009 resulted in a decrease in aggregate backlog. However, net orders for 2010 rebounded from the previous year. Commercial net orders were 1,104 in 2010, resulting in a backlog increase of 132 aircraft. This trend continued in 2011 with net orders of 2,224, resulting in a backlog increase of 1,213 aircraft. High backlog levels are expected to continue to drive increasing production and delivery forecasts in the near to mid-term from both Boeing and Airbus. The following table sets forth the historical deliveries of Boeing and Airbus for 2006 through 2011 and delivery expectations for 2012.

Boeing has announced that it expects its 2012 deliveries to be approximately 585-600 aircraft. Airbus announced that it expects its 2012 deliveries to be approximately 570 in 2012.

New Program Inventory

        Inventory continues to grow in terms of absolute dollars and remains stable as a percentage of total assets. Inventory as a percentage of total assets was 52%, 49% and 49% at December 31, 2011, 2010 and 2009, respectively. This overall trend in inventory is driven primarily by our contractually required investments in new programs, which include the Boeing B747-8, B787, Gulfstream G280 and G650, Airbus A350 XWB, Sikorsky CH-53K and Rolls-Royce BR725 programs. The contracts for these new programs accounted for an increase in inventory from 2010 to 2011 of $71.9 million, which is net of forward-loss charges of $18.3 million, $29.0 million, $81.8 million and $3.0 million recorded in 2011 on our B747-8, Sikorsky CH-53K, G280 and A350 XWB non-recurring wing contracts, respectively. The increases in inventory for new programs in the last few years are a result of the application of the percentage-of-completion method of contract accounting with regard to inventory and revenue recognition. Under this method, investments in new contracts, including contractual pre-production costs and recurring production costs in excess of the projected average cost to manufacture all units in the contract block, initially accumulate in inventory for the related contract. Once production has reached a

52

---

Table of Contents

point where the cost to produce a ship set falls below such projected average cost, the inventory balance for such program will begin to decrease. As many of our new programs are either in the pre-production phase or the early stages of recurring production, we expect that inventory balances will continue to increase in 2012. Deferred inventory costs are evaluated for recoverability through their inclusion in the total costs used in the calculation of each contract's estimated profit margin. When the estimated total contract costs exceed total estimated contract revenues, an inventory reserve is established.

New Program Performance

        We are currently performing work on several new programs, which are in various stages of development. Several of these programs entered flight testing in 2011, including the Gulfstream G280 and Gulfstream G650, which includes the Rolls-Royce BR725. The Boeing B787-8 and Boeing B747-8 have each received FAA and JAA certifications, as well as EASA certification for entry into service, and each program has made first aircraft deliveries to the final customer. We are delivering revenue-generating production units on all of these programs. In 2011, we delivered two revenue-generating test articles on the Sikorsky CH-53K helicopter program. We expect to deliver the remaining test articles by the first quarter of 2013.

        These new programs continue to pose a risk of additional charges and/or forward-loss given the low margins that are currently forecasted and cost pressures that continued throughout 2011. This was a challenging year for some of our new programs as we experienced difficulties in achieving estimated cost targets. As described in more detail below in "— Results of Operations", in the first quarter of 2011, we recorded a forward-loss charge of $28.2 million on the Sikorsky CH-53K helicopter program associated with the decision to proceed with a more traditional design and build approach to manufacture the remaining test units. In the third quarter of 2011, we recorded an additional forward-loss charge of $10.0 million associated with our decision to in-source certain parts that were previously out-sourced. These forward-loss charges were offset in the fourth quarter by a $9.2 million pricing settlement with the customer as we achieved a positive outcome on outstanding pricing negotiations. We expect performance on the Sikorsky CH-53K program to improve as we move through the initial development phase. Cost growth continues to be a risk, but we are working closely with our manufacturing and assembly teams to implement plans to mitigate further losses.

        In the second quarter of 2011, we recorded a forward-loss charge of $53.3 million on our G280 wing program as a result of additional manufacturing cost growth and the inclusion of estimated costs related to our decision to move the manufacturing of wing components on that program to Kinston, North Carolina. In the fourth quarter of 2011, we recorded an additional forward-loss charge of $28.5 million associated with the new manufacturing plan and higher than forecasted assembly and supply chain costs.

        Recognition of an additional forward-loss on these programs continues to be a significant risk and is dependent upon several factors, including our market forecast for these aircraft, our ability to successfully perform under revised design and manufacturing plans, achievement of forecasted cost reductions as we enter into production and our ability to successfully resolve claims and assertions.

        During the fourth quarter of 2011, we recorded a $12.6 million forward-loss charge on the B747-8 fuselage and a $5.7 million forward-loss charge on the B747-8 wing components, as that program has experienced manufacturing cost growth in the early production stage.

        In 2011, we lowered our estimated margin on the G650 program to near break-even, as that program has experienced cost growth as it progresses through the development stage and moves towards FAA certification. Our estimated margin on the initial Rolls-Royce BR725 contract is expected to remain at zero until we are able to realize important cost reduction opportunities.

        On May 12, 2011, Spirit and Boeing entered into the B787 Amendment, which settled certain claims and assertions associated with the development and production of the B787 airplane. Among other things, the B787 Amendment settled a major portion of our B787 development claims and included an agreement by both parties for annual price adjustment reviews beginning in 2013 and revised change provisions and cost recovery plan. As significant terms were included in the estimate process, the B787 Amendment did not have a material impact on the contract profitability estimates as our contract accounting assumptions

53

Table of Contents

for those uncertainties were consistent with the ultimate agreement with Boeing. The B787 contract profitability will depend upon our ability to achieve cost reduction opportunities as we increase production levels in the coming months and years. Contract estimates are expected to remain at break-even margins until we are able to realize these important cost reduction opportunities. Should we not realize these expected cost savings, future forward-losses on this contract could be recognized.

        We also continue to support the development of the A350 XWB fuselage and wing programs. Maintaining profit projections on these programs is dependent upon the program schedule. In the fourth quarter of 2011, we recorded a forward-loss charge of $3.0 million on the A350 XWB wing non-recurring contract associated with increasing engineering change costs. The A350 XWB program could experience significant cost growth if the program schedule experiences delays. Our contract estimates on the non-recurring portion of the A350 XWB wing contract continues to reflect zero margins as we experienced cost growth in 2011.

        The next twelve to eighteen months will be a critical time for all of these development programs as we manufacture the initial units and establish baseline performance for the recurring cost structure. Recognition of additional forward-losses in future periods continues to be a significant risk and will depend upon several factors including our market forecast, our ability to successfully perform under revised design and manufacturing plans, achievement of forecasted cost reductions as we enter into production and our ability to successfully resolve claims and assertions with our customers and supply chain partners, see "Risk Factors — Risk Factors Related to Our Business and Industry."

Basis of Presentation

        The financial statements include Spirit's financial statements and the financial statements of its majority-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America. Investments in business entities in which we do not have control, but have the ability to exercise influence over operating and financial policies, are accounted for by the equity method. Kansas Industrial Energy Supply Company ("KIESC"), a tenancy-in-common with other Wichita companies established to purchase natural gas, is fully consolidated as Spirit owns 77.8% of the entity's equity. All intercompany balances and transactions have been eliminated in consolidation. The Company's U.K. subsidiary uses local currency, the British pound, as its functional currency; the Malaysian subsidiary uses the British pound and our Singapore subsidiary uses the Singapore dollar. All other foreign subsidiaries and branches use the U.S. dollar as their functional currency.

        As part of the monthly consolidation process, the functional currency is translated to U.S. dollars using the end-of-month currency translation rate for balance sheet accounts and average period currency translation rates for revenue and income accounts as defined by FASB authoritative guidance on foreign currency translation.

Critical Accounting Policies

        The following discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to inventory, income taxes, financing obligations, warranties, pensions and other post-retirement benefits and contingencies and litigation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Management believes that the quality and reasonableness of our most critical policies enable the fair presentation of our financial position and results of operations. However, the sensitivity of financial statements to these methods, assumptions and estimates could create materially different results under different conditions or using different assumptions.

Table of Contents

        The following are our most critical accounting policies, which are those that require management's most subjective and complex judgments, requiring the use of estimates about the effect of matters that are inherently uncertain and may change in subsequent periods.

Revenues and Profit Recognition

        A significant portion of the Company's revenues are recognized under long-term, volume-based pricing contracts, requiring delivery of products over several years. The Company recognizes revenue under the contract method of accounting and records sales and profits on each contract in accordance with the percentage-of-completion method of accounting, primarily using the units-of-delivery method. The units-of-delivery method recognizes as revenue the contract price of units of a basic production product delivered during a period and as the cost of earned revenue the costs allocable to the delivered units; costs allocable to undelivered units are reported in the balance sheet as inventory. The method is used in circumstances in which an entity produces units of a basic product under production-type contracts in a continuous or sequential production process to buyers' specifications. Recurring long-term production contracts are usually divided into contract blocks for this purpose, with each block treated as a separate contract for "units-of-delivery" production-type contract accounting purposes.

        The total quantity of production units to be delivered under a contract may be set as a single contract accounting block, or it can be split into multiple blocks. Unless the life of the contract is so long that it prevents reliable estimates, the entire contract quantity will typically be set as the contract accounting block quantity. "Life of program", or "requirements based" contracts often lead to continuing sales of more than twenty years. Since this is much longer than can be reliably estimated, we use parameters based on the contract facts and circumstances to determine the length of the contract block. This analysis includes: considering the customer's firm orders, internal assessment of the market, reliabilities of cost estimates, potential segmentation of non-recurring elements of the contract, and other factors. Contract block sizes may also be determined based on certain contractual terms such as pricing renegotiation dates such that certain contract blocks may use an approximate date instead of a defined unit quantity in order to increase the ability to estimate accurately given that the renegotiated pricing is unknown for the planning block. Shorter contract blocks for mature, ongoing programs are common due to the presence of recent cost history and probable forecast accuracy. Mature program contract blocks tend to be approximately two years in length. Initial contract blocks often require a longer time period and greater number of units in order to take into account the higher cost of early units due to a steeper experience curve and pre-production design costs. Initial contract blocks on new programs can extend up to ten years. As these programs mature and efficiencies are realized, subsequent contract block length shortens to take into account the steady state of the continuing production.

        Revenues from non-recurring design work are recognized based on substantive milestones or use of the cost to cost method, that are indicative of our progress toward completion depending on facts and circumstances. We follow the requirements of FASB authoritative guidance on accounting for the performance of construction-type and certain production-type contracts (the contract method of accounting), using the cumulative catch-up method in accounting for revisions in estimates. Under the cumulative catch-up method, the impacts of revisions in estimates are recognized immediately when changes in estimated contract profitability become known.

        A profit rate is estimated based on the difference between total revenues and total costs over a contract block. Total revenues at any given time include actual historical revenues up to that time plus future estimated revenues. Total costs at any given time include actual historical costs up to that time plus future estimated costs. Estimated revenues include negotiated or expected values for units delivered, estimates of probable recoveries asserted against the customer for changes in specifications, price adjustments for contract and volume changes, and escalation. Costs include the estimated cost of certain pre-production effort (including non-recurring engineering and planning subsequent to completion of final design) plus the estimated cost of manufacturing a specified number of production units. Estimates take into account assumptions relative to future labor performance and rates, and projections relative to material and overhead costs including expected "learning curve" cost reductions over the term of the

55

Table of Contents

contract. Estimated revenues and costs also take into account the expected impact of specific contingencies that we believe are probable.

        Estimates of revenues and costs for our contract blocks span a period of multiple years and are based on a substantial number of underlying assumptions. We believe that the underlying assumptions are sufficiently reliable to provide a reasonable estimate of the profit to be generated. However, due to the significant length of time over which revenue streams will be generated, the variability of the revenue and cost streams can be significant if the assumptions change. Estimates of profit margins for contract accounting blocks are typically reviewed on a quarterly basis. Assuming the initial estimates of sales and costs under the contract block are accurate, the percentage-of-completion method results in the profit margin being recorded evenly as revenue is recognized under the contract block. Changes in these underlying estimates due to revisions in sales and cost estimates may result in profit margins being recognized unevenly over a contract block as such changes are accounted for on a cumulative basis in the period estimates are revised, which we refer to as cumulative catch-up adjustments. When the current estimates of total contract revenue and total contract cost indicate a loss, a provision for the entire loss on the contract, known as a forward-loss charge, is recorded to cost of sales in the period in which it becomes evident.

        For revenues not recognized under the contract method of accounting, the Company recognizes revenues from the sale of products at the point of passage of title, which is generally at the time of shipment. Shipping and handling costs are included in cost of sales. Revenues earned from providing maintenance services including any contracted research and development are recognized when the service is complete or other contractual milestones are attained.

        Since Boeing retained title to tooling assets obtained as part of the Boeing Acquisition and provides such tooling to the Company at no cost, the Company treats the amortization of Boeing-owned tooling as a reduction to revenues as required by FASB authoritative guidance on consideration given by a vendor to a customer, including resellers of the vendor's product. These items are netted against revenues in calculating net revenues. In 2011, the Company recognized no reductions to gross revenues for Boeing tooling, as the tooling became fully amortized in 2010. Under an agreement with Airbus, certain payments that are also accounted for as consideration given by a vendor to a customer will be amortized as a reduction to net revenues beginning in 2012.

        A significant portion of the Company's future revenues is expected to be derived from new programs, on which we may be contracted to provide design and engineering services, recurring production, or both. There are several risks inherent to such new programs. In the design and engineering phase, we may incur costs in excess of our forecasts due to several factors, including cost overruns, customer directed change orders and delays in the overall program. We may also incur higher than expected recurring production costs, which may be caused by a variety of factors, including the future impact of engineering changes (or other change orders) or our inability to secure contracts with our suppliers at projected cost levels. Our ability to recover these excess costs from the customer will depend on several factors, including our rights under our contracts for the new programs. In determining our profits and losses in accordance with the percentage-of-completion method of contract accounting, we are required to make significant assumptions regarding our future costs, as well as the estimated number of units to be manufactured under the contract and other variables. We continually review and update our assumptions based on market trends and our most recent experience. If we make material changes to our assumptions, such as a reduction in the estimated number of units to be produced under the contract (which could be caused by emerging market trends or other factors), an increase in future production costs or a change in the recoverability of increased design or production costs, we may experience negative cumulative catch-up adjustments related to revenues previously recognized. In some cases, we may recognize forward-loss amounts. For a broader description of the various types of risks we face related to new programs, see "Risk Factors — Risk Factors Related to Our Business and Industry."

Inventory

        Raw materials are stated at lower of cost (principally on an actual or average cost basis) or market. Inventoried costs attributed to units delivered under long-term contracts are based on the estimated average cost of all units expected to be produced and are determined under the learning curve concept which anticipates a predictable decrease in unit costs as tasks and production techniques become more efficient through repetition. This usually results in an increase in inventory (referred to as "excess-over-average" or "deferred production costs") during the early years of a contract. These costs are deferred only to the extent the amount of actual or expected excess-over-average is reasonably expected to be fully offset by lower-than-average costs in future periods of a contract. If in-process inventory plus estimated costs to complete a specific contract exceed the actual plus anticipated remaining sales value of such contract, such excess is charged to cost of sales in the period the loss becomes known, thus reducing inventory to estimated realizable value. Costs in inventory include amounts relating to contracts with long production cycles, some of which are not expected to be realized within one year.

        The Company reviews its general stock materials and spare parts inventory each quarter to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends and expected production usage. Impaired inventories are written off to work in process in the period identified.

        Work-in-process inventory includes deferred production costs for the excess of production costs over the estimated average cost per ship set, and credit balances for favorable variances on contracts between actual costs incurred and the estimated average cost per ship set for units delivered under the current production blocks. Recovery of excess over average deferred production costs is dependent on the number of ship sets ultimately sold and the ultimate selling prices and lower production costs associated with future production under these contract blocks. Work-in-process inventory also includes non-recurring production costs. Non-recurring production costs include design and engineering costs and test articles.

        Finished goods inventory is stated at its estimated average per unit cost based on all units expected to be produced.

        Capitalized pre-production costs include certain contract costs, including applicable overhead, incurred before a product is manufactured on a recurring basis. Significant customer-directed work changes can also cause pre-production costs to be incurred. These costs are typically recovered over a certain number of ship set deliveries.

Income Taxes

        Income taxes are accounted for in accordance with FASB authoritative guidance on accounting for income taxes. Deferred income tax assets and liabilities are recognized for the future income tax consequences attributable to differences between the financial statement carrying amounts for existing assets and liabilities and their respective tax bases. A valuation allowance is recorded to reduce deferred income tax assets to an amount that in management's opinion will ultimately be realized. Tax rate changes impacting these assets and liabilities are recognized in the period during which the rate change occurs.

        We record an income tax expense or benefit based on the net income earned or net loss incurred in each tax jurisdiction and the tax rate applicable to that income or loss. In the ordinary course of business, there are transactions for which the ultimate tax outcome is uncertain. These uncertainties are accounted for in accordance with FASB authoritative guidance on accounting for the uncertainty in income taxes. The final tax outcome for these matters may be different than management's original estimates made in determining the income tax provision. A change to these estimates could impact the effective tax rate and net income or loss in subsequent periods. We use the flow-through accounting method for tax credits. Under this method, tax credits reduce income tax expense.

Pensions and Other Post-Retirement Benefits

        We account for pensions and other post-retirement benefits in accordance with FASB authoritative guidance on employers' accounting for pensions, post-retirement benefits other than pensions, defined benefit pension and other post-retirement plans (See Note 13, "Pension and Other Post-Retirement Benefits," for additional detail on these plans).

57

---

Table of Contents

        Assumptions used in determining the benefit obligations and the annual expense for our pension and post-retirement benefits other than pensions are evaluated and established in conjunction with an independent actuary.

        We set the discount rate assumption annually for each of our retirement-related benefit plans as of the measurement date, based on a review of projected cash flows and long-term high-quality corporate bond yield curves. The discount rate determined on each measurement date is used to calculate the benefit obligation as of that date, and is also used to calculate the net periodic benefit expense/(income) for the upcoming plan year.

        We derive assumed expected rate of return on pension assets from the long-term expected returns based on the investment allocation by class specified in our investment policy. The expected return on plan assets determined on each measurement date is used to calculate the net periodic benefit expense/(income) for the upcoming plan year.

        Assumed health care cost trend rates have a significant effect on the amounts reported for the post-retirement health care plans. To determine the health care cost trend rates, we consider national health trends and adjust for our specific plan designs and locations.

Stock Compensation Plans

        At inception, we adopted FASB authoritative guidance which generally requires companies to measure the cost of employee and non-employee services received in exchange for an award of equity instruments based on the grant-date fair value and to recognize this cost over the requisite service period or immediately if there is no service period or other performance requirements. Stock-based compensation represents a significant accounting policy of ours, which is further described in Note 15 within the notes to our consolidated financial statements included in this Annual Report.

        We have established various stock compensation plans that include restricted share grants and restricted stock units.

        Comparative ship set deliveries by model are as follows:

        For purposes of measuring production or ship set deliveries for Boeing aircraft in a given period, the term "ship set" refers to sets of structural fuselage components produced or delivered for one aircraft in such period. For purposes of measuring production or ship set deliveries for Airbus aircraft in a given period, the term "ship set" refers to all structural aircraft components produced or delivered for one aircraft in such period. Other components which are part of the same aircraft ship sets could be produced or shipped in earlier or later accounting periods than the components used to measure production or ship set deliveries, which may result in slight variations in production or delivery quantities of the various ship set components in any given period.

        Net revenues by prime customer are as follows:

Twelve Months Ended December 31, 2011 as Compared to Twelve Months Ended December 31, 2010

        Net Revenues.    Net revenues for the twelve months ended December 31, 2011 were $4,863.8 million, an increase of $691.4 million, or 17%, compared with net revenues of $4,172.4 million for the prior year. The increase in net revenues in 2011 as compared to 2010 was primarily due to the recognition of $236.2 million of deferred revenue for non-recurring work on B787-9 derivative and mission improvement ("DMI") for pricing adjustments on prior and current-year deliveries all resulting from the B787 Amendment, which was finalized in May 2011. In addition, we recorded approximately $291.4 million of higher production volume driven by customer delivery schedules and approximately $44.4 million of

additional aftermarket volume. These increases were partially offset by a decrease of approximately $38.4 million in non-recurring revenue. Net revenues generated from our business jet programs increased during 2011 as we delivered more production ship sets. Non-recurring revenues, which includes design and development efforts, decreased during 2011 as we transitioned to full production on multiple platforms. Deliveries to Boeing increased by 8% to 520 ship sets during 2011 compared to 480 ship sets delivered in the prior year, as ship set deliveries increased across all Boeing programs driven by customer delivery schedules. Deliveries to Airbus increased by 14% to 520 ship sets during 2011 compared to 458 ship sets delivered in the prior year due to increased deliveries across all Airbus programs driven by customer delivery schedule. In total, ship set deliveries increased 12% to 1,089 ship sets in 2011 compared to 969 ship sets for the same period in the prior year. Approximately 95% of Spirit's net revenues for 2011 came from our two largest customers, Boeing and Airbus.

        Cost of Sales.    Cost of sales as a percentage of net revenues was 89% for the twelve months ended December 31, 2011, as compared to 87% in the prior year. The increase in 2011 is primarily due to a net $81.8 million forward-loss charge recognized on our G280 wing program, a net $29.0 million net forward-loss charge recognized on our Sikorsky CH-53K helicopter program, a $18.3 million forward-loss charge recognized on our B747-8 program, a $9.0 million charge to replenish warranty and extraordinary rework reserves, a $3.0 million forward-loss charge on our A350 XWB non-recurring wing contract, and a $1.9 million charge for early retirement incentives for eligible UAW-represented employees. In 2011, we recorded a favorable $13.8 million cumulative catch-up adjustment related to periods prior to 2011 driven by productivity improvements, recognition of favorable performance as we closed out B737 and B777 contract blocks in the fourth quarter, and a lower forecast for our short-term incentive accrual, partially offset by increasing material costs in our Wing Systems segment. In addition, we continue to record zero margins on the B787 program, for which deliveries have increased in the current year.

        In comparison, in the same period of 2010, we recorded $18.9 million associated with the shares granted to eligible IAM-represented employees upon the ratification of a new ten-year agreement, $6.5 million in early retirement incentives also associated with the ten-year IAM agreement, and $3.3 million associated with shares granted to eligible UAW — represented employees at the ratification of a new ten-year contract. We updated our 2010 contract profitability estimates resulting in an unfavorable cumulative catch-up adjustment of $23.2 million driven by a $5.2 million charge on our Hawker 850XP contract related to the decision to exit the program, $7.1 million unfavorable cumulative catch-up adjustment related to periods prior to 2010 on our Sikorsky CH-53K contract as a result of additional costs required to meet test hardware schedules, and $6.5 million recorded in the Propulsion segment primarily due to a comprehensive analysis of our B787 contract in the fourth quarter of 2010, during which we revised our contract estimates to reflect a break even-margin, partially offset by favorable performance trends on mature programs. We also recorded a $2.8 million forward-loss charge for tooling contracts for the G280 program in 2010.

        SG&A, Research and Development.    Combined SG&A and Research and Development costs as a percentage of net revenues was 4% for the twelve months ended 2011, compared to 5% in the prior year. SG&A expense increased $3.9 million for the twelve months ended December 31, 2011, or 3%, primarily due to increase in stock compensation expense of $11.1 million related to grants awarded in 2011, as compared to $7.9 million during the prior year. Research and Development expenses for the twelve months ended December 31, 2011 were down $15.8 million, or 31% compared to the same period in the prior year primarily due to the B787 Amendment, which resulted in a change in the treatment of advances for non-recurring work previously recorded as research and development expense to inventory contract cost. In addition, we had fewer research and development expense was lower due to planned delays of several technology development projects underway in 2011 versus 2010.

        Operating Income.    Operating income for the twelve months ended December 31, 2011 was $356.1 million, which was relatively flat compared to operating income of $357.0 million for the prior year. Operating income in 2011 was favorably impacted by improved operating margins resulting from higher overall production and aftermarket volume, the impact related to the favorable cumulative catch-up, and

Table of Contents

the favorable impact of the change in treatment of advances for non-recurring work previously recorded as research and development expense to inventory contract costs caused by the B787 Amendment. This was partially offset by the forward-loss charges on our G280 wing, Sikorsky CH-53K helicopter, B747-8 and the A350 XWB non-recurring wing contract, a charge to replenish the warranty and extraordinary rework reserve, costs associated with early retirement incentives, and higher stock compensation expense as discussed above. The adjustments related to the B787 Amendment did not contribute to overall operating income as profitability margins on that program are break-even; however, they negatively impacted operating margins as a percentage of net revenues for 2011.

        Interest Expense and Financing Fee Amortization.    Interest expense and financing fee amortization for the twelve months ended December 31, 2011 includes $71.9 million of interest and fees paid or accrued in connection with long-term debt and $5.6 million in amortization of deferred financing costs, as compared to $51.1 million of interest and fees paid or accrued in connection with long-term debt and $8.0 million in amortization of deferred financing costs in the prior year. The increase in interest expense associated with long-term debt in 2011 was primarily driven by interest accrued on our 2020 Notes and on our senior secured term loan as amended in 2010. The decrease in deferred financing costs was related to an adjustment recorded in 2011 to reflect the maturity dates of our term loan and revolving credit facilities over which deferred financing is amortized.

        Interest Income.    Interest income for the twelve months ended December 31, 2011 and December 31, 2010 was $0.3 million.

        Other Income (Expense).    Other income (expense) for 2011 included income of $1.4 million primarily due to income from the KDFA bonds, partially offset by losses due to foreign exchange rates on intercompany activity and borrowings, as compared to expense of ($0.4) million for the same period in the prior year. The increase in other income was driven primarily by the comparatively favorable foreign exchange rates, in 2011, on debt denominated in currencies other than the borrowing entities' functional currency, as compared to the prior year, partially offset by bad debt expense and loss on the disposal of assets.

        Provision for Income Taxes.    Our reported tax rate includes two principal components: an expected annual tax rate and discrete items resulting in additional provisions or benefits that are recorded in the quarter that an event arises. Events or items that give rise to discrete recognition could include finalizing audit examinations for open tax years, statute of limitations expiration, or a stock acquisition.

        The income tax provision for the twelve months ended December 31, 2011, was $86.9 million compared to $78.2 million for the prior year. The 2011 effective tax rate was 31.0% as compared to 26.3% for 2010. The difference in the effective tax rate recorded for 2011 as compared to 2010 is related primarily to settling the 2005 and 2006 U.S. Federal examinations and additional state income tax credits last year, and establishing a reserve this year for the Malaysia tax holiday benefit. The decrease from the U.S. statutory tax rate is attributable primarily to the U.S. federal research tax credit, qualified domestic production activities deduction, and state income tax credits.

        Fuselage Systems.    Fuselage Systems segment net revenues for the twelve months ended December 31, 2011 were $2,425.0 million, an increase of $389.9 million, or 19%, compared to the prior year. The increase in net revenues is due to the recognition of deferred revenue, recognition of revenue from non-recurring work on B787-9 DMI and revenue for pricing adjustments on prior and current-year deliveries all as a result of the B787 Amendment which was finalized in May 2011. In addition, net revenues increased due to higher production volume across all Boeing models and additional aftermarket volume, partially offset by lower revenue from non-recurring efforts, which includes design and development activities. Fuselage Systems posted segment operating margins of 13% for 2011, down from 14% segment operating margins for the prior year, primarily due to the recognition of a $29.0 million net forward-loss charge on our Sikorsky CH-53K helicopter program, a $12.6 million forward-loss charge on our B747-8 program, and the negative impact of the zero margin associated with the B787 on operating margin as a percentage of net revenues as deliveries for that program increased in the current year. In 2011, the segment realized a favorable cumulative catch-up adjustment of $13.6 million related to periods prior to 2011, driven by productivity improvements and a lower forecast for our short-term incentive accrual. In comparison, in the same period of 2010, the segment recognized a $7.2 million unfavorable cumulative catch-up adjustment, which was primarily driven by additional costs to meet test hardware schedules on the Sikorsky CH-53K helicopter program, partially offset by favorable cost performance trends on mature programs.

        Propulsion Systems.    Propulsion Systems segment net revenues for the twelve months ended December 31, 2011 were $1,221.5 million, an increase of $159.7 million, or 15%, compared to the prior year. The increase in net revenues is due to the increase in B747 and B777 deliveries, additional aftermarket volume, and higher revenue from non-recurring efforts, which include design and development efforts. Propulsion Systems posted segment operating margins of 16% for the twelve months ended December 31, 2011 as compared to 13% for the same period in the prior year. In 2011, the segment realized a favorable cumulative catch-up adjustment of $12.8 million, primarily driven by productivity and efficiency improvements and a lower forecast for our short-term incentive accrual. In comparison in the same period of 2010 the segment recognized a $6.5 million unfavorable cumulative catch-up adjustment related to periods prior to 2010, primarily driven by the comprehensive analysis of our B787 contract in the fourth quarter of 2010, during which we revised our contract estimates to reflect a break-even margin.

        Wing Systems.    Wing Systems segment net revenues for the twelve months ended December 31, 2011, were $1,207.8 million, an increase of $140.4 million, or 13%, as compared to the same period in the prior year. The increase in net revenues is due to the recognition of deferred revenue, revenue for non-recurring work on the B787-9 DMI and revenue due to pricing adjustments on prior and current-year deliveries all as a result of the B787 Amendment, which was finalized in May 2011. In addition, net revenues increased due to higher production volume across all models, including deliveries of wings on our Gulfstream programs. Non-recurring net revenue, which includes design and development efforts, decreased in 2011 as we transitioned to full production on multiple platforms. In comparison, in the same period of 2010, Wing Systems delivered fewer ship sets on the A320 and A330/A340 programs due to a customer re-phasing delivery schedule and lower production rates. Wing Systems posted operating margins of less than 1% for 2011, as compared to 10% in the prior year. In 2011, the segment realized an unfavorable cumulative catch-up adjustment of $12.6 million, primarily driven by an increase in material costs, compared to an unfavorable $9.5 million cumulative catch-up adjustment recognized in the same period of the prior year. In 2011, we recognized $81.8 million in forward-loss charges on our G280 program, a $5.7 million forward-loss charge on our B747-8 program and a $3.0 million forward-loss charge on our A350 XWB non-recurring wing contract.

        All Other.    All Other segment net revenues consist of sundry sales of miscellaneous services, tooling contracts, and revenues from KIESC. In the twelve months ended December 31, 2011, All Other segment net revenues were $9.5 million, an increase of $1.4 million, or 17%, as compared to the same period in the prior year. The increase in net revenues was primarily driven by higher tooling revenue. The All Other segment recorded 14% operating margins in 2011, up from negative segment operating margins for the

same period in the prior year driven by increased margins on sundry and tooling sales. In 2010, we recorded a $2.8 million forward-loss charge on our tooling contract for the G280 wing program.

Twelve Months Ended December 31, 2010 as Compared to Twelve Months Ended December 31, 2009

        Net Revenues.    Net revenues for the twelve months ended December 31, 2010 were $4,172.4 million, an increase of $93.9 million, or 2%, compared with net revenues of $4,078.5 million for the prior year. The increase in net revenues is primarily attributable to an increase in ship set deliveries in 2010 for the Boeing B737 as compared to 2009, as the lingering effects of the IAM Strike at Boeing impacted the first quarter 2009 deliveries. In addition, 2010 deliveries for the Boeing B787 also increased driven by customer delivery schedule. Non-recurring revenues, which are derived primarily from engineering and design efforts, were $297.0 million and $328.0 million for each of the twelve month periods ended December 31, 2010 and December 31, 2009, respectively. Favorable volume-based pricing adjustments of $38.0 million were recorded in 2009 as a result of lower deliveries due to the IAM Strike at Boeing as compared with $5.2 million of such adjustments recorded during the same period of 2010. The strengthening dollar during 2010 resulted in an $8.4 million decrease in the value of net revenues from Spirit Europe. Deliveries to Boeing increased by 3% to 480 ship sets during 2010 compared to 466 ship sets delivered in the prior year, mostly due to increases in B737 and B787 ship set deliveries, partially offset by a decrease in B777 ship set deliveries driven by customer delivery schedule. Deliveries to Airbus decreased by 12% to 458 ship sets during 2010 compared to 519 ship sets delivered in the prior year due to a 2010 customer delivery re-phasing at Spirit Europe which reduced third quarter A320 deliveries. We re-aligned with customer A320 delivery levels in the fourth quarter of 2010. In total, ship set deliveries decreased 7% to 957 ship sets in 2010 compared to 1,029 ship sets for the same period in the prior year. This was primarily attributable to reduced deliveries of Hawker, A320 and A330 ship sets, which are not a significant source of revenue, partially offset by increased Boeing ship set deliveries. Approximately 94% of Spirit's net revenues for 2010 came from our two largest customers, Boeing and Airbus.

        Cost of Sales.    Cost of sales as a percentage of net revenues was 87% for the twelve months ended December 31, 2010, as compared to 88% in the prior year. The decrease in 2010 is primarily due to the absence of unusual charges recorded in 2009, consisting of $103.9 million related to a forward-loss on our G280 contract and the Cessna Citation Columbus program termination, as well as an unfavorable cumulative catch-up adjustment of $58.5 million in 2009. During 2010, we recorded expenses of approximately $18.9 million associated with the shares granted to eligible IAM-represented employees at the ratification of a new ten-year agreement on June 25, 2010, $6.5 million in early retirement incentives accepted by IAM-represented employees in the third quarter of 2010 also in accordance with the new ten-year contract, and $3.3 million associated with shares granted to eligible UAW-represented employees at the ratification of a new ten-year contract on December 18, 2010. We updated our 2010 contract profitability estimates resulting in an unfavorable cumulative catch-up adjustment of $23.2 million driven by a $5.2 million charge on our Hawker 850XP contract related to the decision to exit the program, $7.1 million unfavorable cumulative catch-up adjustment related to periods prior to 2010 on our Sikorsky CH-53K contract as a result of additional costs required to meet test hardware schedules, and $6.5 million recorded in the Propulsion segment primarily driven by the fourth quarter of 2010 comprehensive analysis of our 787 contract, during which we revised our contract estimates to reflect a break even margin, partially offset by favorable performance trends on mature programs. We also recorded a $2.8 million forward-loss charge for tooling contracts for the G280 program in 2010. In addition to these specific charges, we continue to experience lower profitability on follow-on production blocks that began in the fourth quarter of 2009.

        In January 2010, we adopted a change in accounting estimate which extended the useful lives of certain assets. The effect of this change was a decrease in depreciation charges of $14.6 million to inventory for 2010, which will eventually flow through cost of sales following the process for contract accounting.

        SG&A, Research and Development.    Combined SG&A and Research and Development costs as a percentage of net revenues were 5% for both of the twelve month periods ended December 31, 2010 and December 31, 2009. SG&A expense increased $18.9 million, or 14%, primarily due to early retirement incentives offered in 2010, as well as additional SG&A expenses incurred as we expanded our global footprint to Malaysia, North Carolina and France. In addition, we recognized $7.9 million in stock compensation expense in SG&A during the twelve months ended December 31, 2010, as compared to $9.7 million during the same period in the prior year. Research and Development expenses for the twelve months ended December 31, 2010 were down $5.2 million, or 9% compared to the same period in the prior year due to the completion of certain A350 XWB related R&D work in 2009.

        Operating Income.    Operating income for the twelve months ended December 31, 2010 was $357.0 million, an increase of $53.7 million, or 18%, compared to operating income of $303.3 million for the prior year. Operating income increased in 2010 primarily due to the absence of charges similar in nature to those recorded in the second quarter of 2009 that are discussed above, partially offset by the decrease in volume-based pricing adjustments recorded in 2010, the stock award charge recorded in 2010 related to the ratification by IAM-represented employees as the result of a new ten-year agreement, charges associated with the early retirement incentives offered in 2010 as part of that contract, and the stock award charge recorded in 2010 related to the ratification by UAW-represented employees of a new ten-year agreement. Operating margins continued to reflect the reduced profitability on follow-on production blocks as compared with 2009.

        Interest Expense and Financing Fee Amortization.    Interest expense and financing fee amortization for the twelve months ended December 31, 2010 includes $51.1 million of interest and fees paid or accrued in connection with long-term debt and $8.0 million in amortization of deferred financing costs, as compared to $37.1 million of interest and fees paid or accrued in connection with long-term debt and $6.5 million in amortization of deferred financing costs in the prior year. In June 2009, the Company amended its credit facility which resulted in an increase in amortized deferred financing costs. The increase in interest expense in 2010 was primarily driven by interest on the senior unsecured notes issued at the end of the third quarter in 2009, partially offset by interest incurred on the drawn portion of the revolver in 2009. The increase in deferred financing fees was primarily the result of a full-year discount amortization in 2010 on the notes issued in the third quarter of 2009.

        Interest Income.    Interest income for the twelve months ended December 31, 2010 was $0.3 million, as compared to $7.0 million for the same period in the prior year, which included $6.5 million of accretion of the discounted long-term receivable from Boeing for capital expense reimbursement pursuant to the Asset Purchase Agreement for the Boeing Acquisition. The last of these payments for capital reimbursement was made by Boeing to the Company in 2009.

        Other Income (Expense).    Other income (expense) for 2010 included expense of ($5.0) million due to changes in foreign exchange rates on intercompany activity and borrowings, as compared to income of $2.3 million for the same period in the prior year. The increase in expense was driven primarily by the intercompany payable from Spirit Europe to Spirit related to our A350 XWB program, as well as trade payables and borrowings. Should these balances increase, they will be more susceptible to changes in exchange rates.

        Provision for Income Taxes.    Our reported tax rate includes two principal components: an expected annual tax rate and discrete items resulting in additional provisions or benefits that are recorded in the quarter that an event arises. Events or items that give rise to discrete recognition could include finalizing audit examinations for open tax years, statute of limitations expiration, or a stock acquisition.

        The income tax provision for the twelve months ended December 31, 2010, was $78.2 million compared to $80.9 million for the prior year. The 2010 effective tax rate was 26.3% as compared to 29.7% for 2009. The decrease in the effective tax rate recorded for 2010 is related primarily to settling the 2005 and 2006 U.S. federal examinations, additional state income tax credits, and our tax holiday in Malaysia.

Table of Contents

The decrease from the U.S. statutory tax rate is attributable primarily to the U.S. federal research tax credit, qualified domestic production activities deduction, state income tax credits, and our tax holiday in Malaysia.

        Segments.    Fuselage Systems, Propulsion Systems, Wing Systems and All Other represented approximately 49%, 25%, 26% and less than 1% respectively, of our net revenues for the twelve months ended December 31, 2010. Revenues attributable to Airbus are recorded within Wing Systems. Fuselage Systems, Propulsion Systems, Wing Systems and All Other represented approximately 55%, 26%, 19% and less than 1%, respectively, of our operating income before unallocated corporate expenses for the year ended December 31, 2010.

        Fuselage Systems.    Fuselage Systems segment net revenues for the twelve months ended December 31, 2010, were $2,035.1 million, an increase of $31.5 million, or 2%, compared to the same period in the prior year. This reflects an increase in deliveries of B737 and B787 ship sets in 2010, partially offset by a decrease in deliveries of B777 ship sets in 2010, as compared to the prior year. Fuselage Systems posted segment operating margins of 14% for each of the twelve month periods ended December 31, 2010 and December 31, 2009. Lower overall margins on follow-on production blocks impacted segment operating margins in 2010, while a $10.9 million charge for the Cessna Citation Columbus program termination and an unfavorable cumulative catch-up of $29.9 million were recorded in 2009 related to periods prior to 2009. During 2010, the segment realized an unfavorable cumulative catch-up adjustment of $7.2 million related to periods prior to 2010, primarily driven by additional costs required to meet test hardware schedules on the Sikorsky CH-53K program, partially offset by favorable performance on mature programs.

        Propulsion Systems.    Propulsion Systems segment net revenues for the twelve months ended December 31, 2010 were $1,061.8 million, an increase of $31.8 million, or 3%, as compared to the same period in the prior year. This reflects an increase in deliveries of B737 and B787 ship sets in 2010, partially offset by a decrease in deliveries of B777 ship sets in 2010, as compared to the prior year. Propulsion Systems posted segment operating margins of 13% for the twelve months ended December 31, 2010 as compared to 12% for the same period in the prior year. Lower overall margins on follow-on production blocks impacted segment operating margin in 2010, while an unfavorable cumulative catch-up adjustment of $22.4 million was recorded in 2009 related to periods prior to 2009. During 2010, the segment realized an unfavorable cumulative catch-up adjustment of $6.5 million related to periods prior to 2010, primarily driven by the fourth quarter of 2010 comprehensive analysis of our B787 contract, during which we revised our contract estimates to reflect a break-even margin.

        Wing Systems.    Wing Systems segment net revenues for the twelve months ended December 31, 2010 were $1,067.4 million, an increase of $43.0 million, or 4%, as compared to the same period in the prior year. This reflects an increase in revenues related to engineering and development work on our new programs. Wing Systems posted operating margins of 10% for 2010, as compared to 2% in the prior year, primarily due to the $90.5 million forward-loss charge on the G280 contract recorded during 2009 and an unfavorable cumulative catch-up adjustment of $6.2 million recorded in 2009 related to periods prior to 2009. During 2010, the segment realized an unfavorable cumulative catch-up adjustment of $9.5 million related to periods prior to 2010.

        All Other.    All Other segment net revenues consist of sundry sales of miscellaneous services, tooling contracts, and revenues from KIESC. In the twelve months ended December 31, 2010, All Other segment net revenues were $8.1 million, a decrease of $12.4 million, or 60%, as compared to the same period in the prior year. The decrease in net revenues was primarily driven by a decrease in third party tooling sales. The All Other segment recorded negative operating margins in both years due to an additional forward-loss charge on a tooling contract for the G280 program of $2.5 million in 2009 and $2.8 million in 2010.

Liquidity and Capital Resources

        The primary sources of our liquidity include cash on hand, cash flow from operations, which include advance payments and receivables from customers, borrowings available under our revolving credit facility and proceeds from our bond issuances. Our liquidity requirements are driven by our long-cycle business model. Our business model is comprised of four to six year non-recurring investment periods, which include design and development efforts, followed by ten to twenty years of recurring production. The non-recurring investment periods require significant outflows of cash as we design the product, build tooling, purchase equipment and build initial production inventories. These activities are typically funded partially through customer advances and milestone payments, which are offset against revenue as production units are delivered in the case of customer advances, or recognized as revenue as milestones are achieved in the case of milestone payments. The remaining funds needed to support non-recurring programs come from predictable cash inflows from our mature programs that are in the recurring phase of the production cycle. Occasionally, we have utilized borrowings and other sources of cash to fund non-recurring investments during periods where cash received from our customers is not adequate to fund our purchase commitments. The non-recurring investment period typically ends concurrently with initial deliveries of completed aircraft by our customers, which indicates that a program has entered into the recurring production phase. When a program reaches steady recurring production, it typically results in long-term generation of cash from operations. As part of our business model, we continuously add new non-recurring programs, which are supported by mature programs that are in the steady recurring phase of the production cycle to promote growth.

        In 2011, we had multiple programs in the non-recurring investment phase requiring capital investment that was funded by cash from operations and cash from our senior notes issued in 2009 and 2010. During the year, several of these programs, including the B787-8 and B747-8, moved into the production phase and began generating cash inflows in 2011. Additional programs are expected to complete their non-recurring phase and enter into the recurring production phase in 2012.

        As of December 31, 2011, we had $177.8 million of cash and cash equivalents on the balance sheet and $630.1 million of available borrowing capacity under our revolving credit facility, which is net of $19.9 million in letters of credit. We had no outstanding balances under our revolving credit facility at the end of 2011. On January 9, 2012, we drew down $100.0 million from our revolving credit facility to fund short-term working capital needs. Historically, cyclical cash flows dictate lower cash balances during the first quarter of the year. Based on our planned levels of operations and our strong liquidity position, we currently expect that our cash on hand, cash flow from operations and borrowings available under our revolving credit facility will be sufficient to fund our operations, inventory growth (as discussed below), planned capital investments, research and development expenditures and scheduled debt service payments for at least the next twelve months.

Cash Flows

        The following table provides a summary of our cash flow for the years ended December 31, 2011, December 31, 2010, and December 31, 2009:

Twelve Months Ended December 31, 2011 as Compared to Twelve Months Ended December 31, 2010

        Operating Activities.    For the twelve months ended December 31, 2011, we had a net cash outflow of $47.3 million from operating activities, an increase in the use of cash of $172.4 million, compared to a net cash inflow of $125.1 million for the prior year. Operating cash consumption increased year-over-year by approximately $517.2 million driven by continued growth in inventory to support engineering development and start-up production costs for new programs as well as costs for ramp-up activities for increasing build rates on several Boeing programs. In addition, we paid $26.6 million in profit sharing in 2011, which was included in inventory, compared to zero paid for 2010. Cash receipts increased year-over-year by approximately $469.7 million driven by additional revenue from unit deliveries and aftermarket volume. In the fourth quarter of 2010, we received a deferred revenue payment of $236.2 million as part of the memorandum of agreement that led to the B787 Amendment.

        The $47.3 million net cash outflow for the twelve months ended December 31, 2011 was largely the result of approximately $4.52 billion in expenditures driven by continued growth in inventory to support engineering development and start-up production costs for new programs, including the B787, A350 XWB and Gulfstream programs, and for ramp-up activities for increasing build rates on the B737 and B777 programs, partially offset by cash receipts of approximately $4.47 billion driven by revenue from unit deliveries, which increased across all Boeing and Airbus models, and aftermarket volume. The $125.1 million net cash inflow in 2010 was largely due to cash receipts of approximately $4.00 billion driven by revenue from unit deliveries and the receipt of a deferred revenue payment of $236.2 million in the fourth quarter of 2010 as part of the memorandum of agreement that led to the B787 Amendment, partially offset by expenditures of approximately $4.13 billion primarily for inventory. The revenue we recognized upon delivery of B787 ship sets in the first nine months of 2011 and for the twelve months of 2010 did not result in cash receipts, resulting instead in the liquidation of customer advances. Cash payments for B787 units resumed in the third quarter of 2011.

        Investing Activities.    For the twelve months ended December 31, 2011, we had a net cash outflow of $249.2 million from investing activities, a decrease in outflow of $39.2 million as compared to a net cash outflow of $288.4 million for the same period in the prior year. In 2011, capital expenditures consisted of purchases of tooling and machinery and equipment to prepare for the manufacturing of our A350 XWB and B787 programs. In addition, we bought machinery and equipment to support the increased production rate of the B737. In comparison, in 2010, capital expenditures increased as the result of set-up of our facilities in Kinston, North Carolina and Saint-Nazaire, France.

        Financing Activities.    For the twelve months ended December 31, 2011, we had a net cash outflow of $6.7 million from financing activities primarily due to principal payments on debt, a decrease in cash flow of $284.1 million compared to a net cash inflow of $277.4 million for the same period in the prior year. We received proceeds of $300.0 million from bond issuances in 2010, partially offset by additional deferred financing costs associated with the bond offerings, as compared to zero cash received from financing activities in 2011.

Twelve Months Ended December 31, 2010 as Compared to Twelve Months Ended December 31, 2009

        Operating Activities.    For the twelve months ended December 31, 2010, we had a net cash inflow of $125.1 million from operating activities, an increase of $139.0 million compared to a net cash outflow of $13.9 million for the same period in the prior year. Net cash provided by operating activities in 2010 was primarily driven by an increase in cash receipts from unit deliveries combined with a deferred revenue payment of $236.2 million as part of the memorandum of agreement that led to the B787 Amendment, partially offset by the slowing of new program inventory growth on programs other than B787 (which is ramping up production). This overall improvement was partially offset by a decrease in advance payments as increased deliveries of the B787 liquidated advances previously received, and a decline in accounts payable and accrued liabilities in 2010. In 2009, we benefited from a change in accounts payable terms which occurred in the first quarter of 2009. Our overall trend of inventory growth is driven primarily by our contractually required investments in new programs which include the Boeing B787, Gulfstream G280 and G650, Airbus A350 XWB, Sikorsky CH-53K and Rolls-Royce BR725 programs. The contracts for these new programs accounted for an increase in inventory in 2010 of $385.9 million, as compared to an increase of $317.3 million in 2009. We expect these programs will continue to drive inventory growth as we incur additional up-front costs to produce initial units, which traditionally have a higher cost. The mature Boeing and Airbus program inventories decreased $48.6 million in 2010 as compared with a $2.3 million increase for these contracts in 2009. In 2010, inventory balances decreased $36.3 million on remaining programs, including non-program specific inventory, as compared to an increase in inventory balances of $5.4 million for the same period in the prior year.

        Investing Activities.    For the twelve months ended December 31, 2010, we had a net cash outflow of $288.4 million from investing activities, an increase in outflow of $176.0 million, as compared to a net cash outflow of $112.4 million for the same period in the prior year. The primary driver in the increased use of cash between periods was the final payment of the long-term receivable from Boeing in December 2009, which resulted in a cash benefit of $115.4 million in 2009 with no corresponding benefit in 2010. During 2010, we invested $288.1 million in property, plant and equipment, software and program tooling, which was $59.9 million higher than during the same period in the prior year, as the result of set-up of our facilities in Kinston, North Carolina and Saint-Nazaire, France.

        Financing Activities.    For the twelve months ended December 31, 2010, we had a net cash inflow of $277.4 million from financing activities, an increase in cash flow of $1.3 million, compared to a net cash inflow of $276.1 million for the same period in the prior year. We received proceeds of $300.0 million and $293.4 million, net of the bond discount, from bond issuances in 2010 and 2009, respectively, partially offset by additional deferred financing costs associated with the bond offerings. Spirit repaid $150.0 million and $200.0 million of borrowings under its senior secured credit facility using a portion of the bond proceeds in 2010 and 2009, respectively.

Future Cash Needs and Capital Spending

        Our primary future cash needs will consist of working capital, debt service, research and development and capital expenditures. We expend significant capital as we undertake new programs, which begin in the non-recurring investment phase of our business model. In addition, we expend significant capital to meet increased production rates on certain mature programs, including the B737. We also require capital to develop new technologies for the next generation of aircraft, and are evaluating various plans to relieve capacity constraints for the announced customer production rate increases. Capital expenditures totaled approximately $249.7 million and $288.1 million for the twelve months ended December 31, 2011 and December 31, 2010, respectively. We expect capital expenditures for the full year 2012 to be approximately $250 million as we prepare for anticipated production rate increases. We plan to fund future capital expenditures and cash requirements from cash on hand, cash generated by operations, customer cash advances and borrowings available under our revolving credit facility.

Tax Payments

        Total tax payments, net of refunds, were $5.6 million in 2011, $34.9 million in 2010 and $95.7 million in 2009. Year-over-year changes are due to changes in legislation and levels and mix of taxable income.

Pension and Other Post-Retirement Benefit Obligations

        Our U.S. pension plan remained fully funded at year-end 2011, and we anticipate non-cash pension income for 2012 to remain at the same level. Our plan investments are broadly diversified and we do not anticipate a near-term requirement to make cash contributions to our U.S. pension plan. We continue to make contributions to our U.K. pension plan. Our projected contributions to the U.K. pension plan for 2012 are $8.6 million.

Debt and Other Financing Arrangements

        Senior Secured Credit Facilities.    We are a party to a credit agreement that consists of a senior secured term loan and a senior secured revolving line of credit. On October 15, 2010, we entered into Amendment No. 3 to the credit agreement. As a result of the amendment, among other things, the revolving credit commitment was increased from $408.8 million to $650.0 million and the maturity date of the revolving credit commitment was extended to September 30, 2014. The credit agreement amendment also extended the maturity date for $437.4 million of the outstanding term loan to September 30, 2016. The maturity date for the $130.2 million balance of the outstanding term loan remains September 30, 2013. The entire asset classes of Spirit, including inventory and property, plant and equipment, are pledged as collateral for both the term loan and the revolving credit facility. As of December 31, 2011, we were and expect to continue to be in full compliance with all covenants contained within our credit agreement. As of December 31, 2011, approximately $561.9 million was outstanding under the term loan, no borrowings were outstanding under the revolving credit facility and $19.9 million of letters of credit were outstanding.

        The Company can borrow funds under its revolving credit agreement as either (i) a Eurodollar Loan, based on LIBOR or, (ii) an Alternate Base Rate (ABR) Loan based on a rate defined in our credit agreement, plus an applicable margin as set forth in the table below:

At December 31, 2011, the Company's total leverage ratio was 2.44:1.0 resulting in applicable margins of 3.50% and 2.50% on Eurodollar and ABR Loans, respectively.

Table of Contents

        In addition to paying interest on outstanding principal under the senior secured credit facility, Spirit is required to pay an unused line fee of 75 basis points on the unused portion of the commitments under the revolving credit facility. Spirit is required to pay participation fees equal to the applicable margin for LIBOR rate revolving credit borrowings with respect to letters of credit issued under the revolving credit facility. Spirit is also required to pay to the issuing banks under its senior secured credit facility letter of credit fronting fees in respect of letters of credit equal to 25 basis points per year, and to the administrative agent thereunder customary administrative fees.

        Senior Notes.    On November 18, 2010, we issued $300.0 million aggregate of 6³/4% Senior Notes due 2020 (the "2020 Notes"), with interest payable on June 15 and December 15 of each year, beginning June 15, 2011. The 2020 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by the Company and Spirit's existing and future domestic subsidiaries that guarantee Spirit's obligations under Spirit's senior secured credit facility. The carrying value of the 2020 Notes was $300.0 million as of December 31, 2011.

        On September 30, 2009, we issued $300.0 million of 7¹/2% Senior Notes due October 1, 2017 (the "2017 Notes"), with interest payable on April 1 and October 1 of each year, beginning April 1, 2010. The 2017 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by the Company and Spirit's existing and future domestic subsidiaries that guarantee Spirit's obligations under Spirit's senior secured credit facility. The carrying value of the 2017 Notes was $294.9 million as of December 31, 2011.

        As of December 31, 2011, we were and expect to continue to be in full compliance with all covenants contained in the indentures governing the 2020 Notes and the 2017 Notes for the foreseeable future.

        Advances and Deferred Revenue on the B787 Program.    In December 2010, Spirit and Boeing entered into an MOA and a settlement agreement regarding certain claims associated with the development and production of the B787 airplane. As part of these agreements, Spirit received a payment of $236.2 million which was recorded as deferred revenue (short-term) within the December 31, 2010 consolidated balance sheet pending finalization of a contract amendment which would contain the final settlement terms. On May 12, 2011, Spirit and Boeing entered into the B787 Amendment, which finalized substantially all of the provisions of the December 2010 MOA. Among other things, the B787 Amendment spread out repayment of a $700.0 million cash advance made by Boeing to Spirit in 2007 to be offset against the purchase price of the first 1,000 B787 ship sets delivered to Boeing, instead of the first 500 ship sets. In the event Boeing does not take delivery of 1,000 ship sets prior to the termination of the B787 program or the B787 Supply Agreement, any advances not then repaid will be applied against any outstanding payments then due by Boeing to us, and any remaining balance will be repaid in annual installments of $42.0 million due on December 15th of each year until the advance payments have been fully recovered by Boeing. Advance payments made to Spirit in 2008 in the amount of $396.0 million for production articles were applied against the full purchase price of the ship sets delivered and were fully liquidated by December 31, 2011. During the third quarter of 2011, cash payments for the B787 units resumed. The B787 Amendment also changed the treatment of advances paid by Boeing for certain non-recurring work into a nonrefundable payment in full for such work. As of December 31, 2011, the amount of advance payments and deferred revenue received by us from Boeing under the B787 Supply Agreement and not yet repaid or recognized as revenue was approximately $629.1 million.

        North Carolina Grant.    On May 14, 2008, we entered into an Inducement Agreement, a Construction Agency Agreement and a Lease Agreement with The North Carolina Global TransPark Authority ("GTPA") for the construction and lease of a manufacturing facility in Kinston, North Carolina (the "NC Facility"). The lease is for an initial term of 22 years, with options for up to four additional 20-year terms, and provides nominal rental payments. The grand opening of the facility was held July 1, 2010. Construction was funded from a $100.0 million grant, awarded to GTPA by the Golden L.E.A.F. (Long-Term Economic Advancement Foundation), Inc. Under the agreements, Spirit is obligated to make a minimum capital investment of $80.0 million by 2014. Failure to make the additional required investment

or meet certain performance criteria, including creation of targeted number of jobs, will result in additional payments to GTPA in future periods. As of December 31, 2011, $100.0 million of the grant funding had been disbursed and 100 percent of Spirit's obligated capital investment had been made, and we expect to meet all performance criteria. We currently manufacture a portion of the fuselage and the Composite Front Spar for the new Airbus A350 XWB aircraft at the NC Facility.

        Malaysian Facility Agreement.    On June 2, 2008, Spirit Malaysia entered into a Facility Agreement ("Facility Agreement") for a term loan facility for Ringgit Malaysia RM69.2 million (approximately USD $20.0 million equivalent) (the "Malaysia Facility"), with the Malaysian Export-Import Bank. The Malaysia Facility requires quarterly principal repayments of RM3.3 million (USD $1.0 million equivalent) from September 2011 through May 2017 and quarterly interest payments payable at a fixed interest rate of 3.5% per annum. The Malaysia Facility loan balance as of December 31, 2011 was $16.1 million.

        French Factory Capital Lease Agreement.    On July 17, 2010, the Company's indirect wholly-owned subsidiary, Spirit AeroSystems France SARL ("Spirit France") entered into a capital lease agreement for €9.0 million (approximately USD $13.1 million equivalent) with BNP Paribas Bank ("BNP") to be used towards the construction of an assembly plant in Saint-Nazaire, France (the "Saint-Nazaire Project"). Lease payments are variable, subject to the three-month Euribor rate plus 2.2%. Lease payments under the agreement are due quarterly through April 2025. As of December 31, 2011, the Company has $11.4 million in debt attributable to the capital lease transaction. We currently assemble center fuselage frame sections and wings for the new Airbus A350 XWB aircraft at the Saint-Nazaire facility.

        Tax Incentive Bonds.    Both Spirit and the Predecessor utilized City of Wichita issued Industrial Revenue Bonds (IRBs) to finance self-constructed and purchased real and personal property at the Wichita site. The bonds issued in 2011, 2010, 2009, 2008, 2006, and 2005 mature ten years from issuance while the bonds issued in 1998 through 2004 mature 25 years after their issuance. Tax benefits associated with IRBs include provisions for a ten-year complete property tax abatement and a Kansas Department of Revenue sales tax exemption on all IRB funded purchases. Spirit and the Predecessor purchased these IRBs, so they are both bondholders and debtor / lessee for the property purchased with the IRB proceeds. Therefore, we offset the amounts invested and obligations for these bonds on a consolidated basis.

        Certain Predecessor property that was subject to Predecessor-owned IRBs continues to be subject to those IRBs. In connection with the Boeing Acquisition, the Predecessor assigned its leasehold interest in IRB-funded assets and the related bonds to a special purpose trust beneficially owned by Boeing which subleases these assets to Spirit. Pursuant to the sublease terms, the special purpose trust will purchase the assets from the City of Wichita, terminate the leases between the City and the Predecessor, redeem the bonds, and transfer the assets to Spirit when these assets cease to qualify for the ten-year property tax abatement.

        The face value for the bonds subleased from the special purpose trust is approximately $296.4 million. In addition, Spirit obtained IRBs in 2005, 2006, 2008, 2009, 2010 and 2011 with a $286.2 million aggregate principal amount. Spirit redeemed $26.9 million of IRBs issued in 2006 in 2009.

        We have an incentive agreement with the Kansas Department of Commerce, pursuant to which the Kansas Development Finance Authority ("KDFA") issued bonds and provided loans to finance eligible projects. The program's purpose is to provide us with incentives to invest in the State of Kansas. To induce this investment, the Kansas Department of Revenue will rebate certain payroll taxes until the bonds are redeemed or mature. Pursuant to offset provisions in the underlying debt instruments, there are no principal or interest cash payments associated with the bonds. As debtor, Spirit offsets the amount owed to its wholly-owned subsidiary, Spirit AeroSystems Finance, Inc., as bondholder. Therefore, we may offset the amounts invested and obligations for these bonds on a consolidated basis. The $80.0 million in debt instruments will expire in December 2025.

Credit Ratings

        Our credit rating remains unchanged at the end of 2011, with a BB rating, stable outlook, by Standard & Poor's and a Ba2 rating, stable outlook, by Moody's Investor Services.

        Our credit ratings are reviewed periodically by the rating agencies listed above.

        The credit rating agencies consider many factors when assigning their ratings, such as the global economic environment and its possible impact on our financial performance, including certain financial metrics used by the rating agencies in determining our credit ratings. Accordingly, it is possible the rating agencies could downgrade our credit ratings from their current levels. This could significantly influence the interest rate of any future debt financings.

        A debt security credit rating is not a recommendation to buy, sell or hold a security. Each rating is subject to revision or withdrawal at any time by the assigning rating organization. Each rating agency has its own methodology for assigning ratings. Accordingly, each rating should be considered independent of other ratings.

Contractual Obligations

        The following table summarizes our contractual cash obligations as of December 31, 2011:

---

(1)

Does not include repayment of $629.1 million of B787 advances or deferred revenue credits to Boeing, which are reflected in our consolidated balance sheet as short-term and long-term liabilities. See Note 7, Advance Payments and Deferred Revenue/Credits.

(2)

The $15.5 million of unrecognized tax benefit liability for uncertain tax positions has been excluded from this table due to uncertainty involving the ultimate settlement period. See Note 16, Income Taxes.

(3)

Interest on our Term Loan B was calculated for all years using the three-month LIBOR yield curve as of December 31, 2011 plus applicable margin.

(4)

Treats the financing of software license purchases and direct financing of system implementation as capital leases.

(5)

For 2012, includes $30.5 million of the tax and interest due on prior years' tax returns.

(6)

Purchase obligations represent computing, tooling costs, and property, plant and equipment commitments at December 31, 2011.

Off-Balance Sheet Arrangements

        Other than operating leases disclosed in the notes to our financial statements included in this Annual Report, we have not entered into any off-balance sheet arrangements as of December 31, 2011.

Tax

        We establish reserves in accordance with FASB authoritative guidance to provide for additional income taxes that may be due in future years as these previously filed tax returns are audited. We recognize the financial statement impact for tax positions only after determining that based on its technical merits the relevant tax authority would more likely than not sustain the position on audit. For tax positions meeting the "more likely than not threshold" the amount recognized in the financial statements is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. The reserves are adjusted quarterly to reflect changes in facts and circumstances, such as the tax audit's progress, case law developments, and new or emerging legislation. We believe that with an $8.4 million long-term payable, the tax reserves are adequate and reflect the most probable outcome for all tax contingencies known at December 31, 2011. Accordingly, the tax contingency liability is included as a non-current liability in our consolidated balance sheet.

Expected Backlog

        As of December 31, 2011, our expected backlog associated with large commercial aircraft, regional jet, business jet, and military equipment deliveries through 2016, calculated based on contractual product prices and expected delivery volumes, was approximately $31.8 billion. This is an increase of $3.5 billion from our corresponding estimate as of the end of 2010 reflecting the fact that Airbus and Boeing new orders exceeded deliveries in 2011. Backlog is calculated based on the number of units Spirit is under contract to produce on our fixed quantity contracts, and Boeing and Airbus announced backlog on our supply agreements. The number of units may be subject to cancellation or delay by the customer prior to shipment, depending on contract terms. The level of unfilled orders at any given date during the year may be materially affected by the timing of our receipt of firm orders and additional airplane orders, and the speed with which those orders are filled. Accordingly, our expected backlog as of December 31, 2011 may not necessarily represent the actual amount of deliveries or sales for any future period.

Foreign Operations

        We engage in business in various non-U.S. markets. As of December 31, 2011, we have a foreign subsidiary with one facility in the United Kingdom, which serves as a production facility, an assembly facility in Malaysia, a worldwide supplier base, and a repair center for the European and Middle-Eastern regions. We purchase certain components and materials that we use in our products from foreign suppliers and a portion of our products will be sold directly to foreign customers, including Airbus, or resold to foreign end-users (i.e., foreign airlines and militaries). In addition, we have built a new assembly facility in Saint-Nazaire, France to receive and assemble center fuselage frame sections for the Airbus A350 XWB commercial aircraft from the facility in Kinston, North Carolina before they are shipped to Airbus. The new facility began operations in 2011.

        Spirit is party to a joint-venture operation with Russian-based Progresstech LTD. The company, known as Spirit-Progresstech LLC, which operates primarily from a branch office located in Moscow, Russia, provides aerospace engineering support services.

        Spirit is also party to a joint venture with Hong Kong Aircraft Engineering Company Limited (HAECO), and its subsidiary, Taikoo Aircraft Engineering Company Limited (TAECO), Cathay Pacific Airways Limited, and Cal-Asia to develop and implement a state-of-the-art composite and metal bond component repair station in the Asia-Pacific region. The service center is called Taikoo Spirit AeroSystems Composite Co. Ltd.

        Currency fluctuations, tariffs and similar import limitations, price controls and labor regulations can affect our foreign operations. Other potential limitations on our foreign operations include expropriation, nationalization, restrictions on foreign investments or their transfers and additional political and economic risks. In addition, the transfer of funds from foreign operations could be impaired by any restrictive regulations that foreign governments could enact.

        Sales to foreign customers are subject to numerous additional risks, including the impact of foreign government regulations, political uncertainties and differences in business practices. There can be no assurance that foreign governments will not adopt regulations or take other actions that would have a direct or indirect adverse impact on our business or market opportunities with such governments' countries. Furthermore, the political, cultural and economic climate outside the United States may be unfavorable to our operations and growth strategy.

        For the twelve months ended December 31, 2011, our net revenues from direct sales to non-U.S. customers were approximately $653.1 million, or 13%, of total net revenues for the same period. For the twelve months ended December 31, 2010, our net revenues from direct sales to non-U.S. customers were approximately $498.4 million, or 12%, of total net revenues for the same period. For the twelve months ended December 31, 2009, our net revenues from direct sales to non-U.S. customers were approximately $575.9 million, or 14%, of total net revenues for the same period.

Inflation

        A majority of our sales are conducted pursuant to long-term contracts that set fixed unit prices, some of which provide for price adjustment for inflation. In addition, we typically consider expected inflation in determining proposed pricing when we bid on new work. Although we have attempted to minimize the effect of inflation on our business through these protections, sustained or higher than anticipated increases in costs of labor or materials could have a material adverse effect on our results of operations.

        Spirit's contracts with suppliers currently provide for fixed pricing in U.S. dollars. Spirit Europe's supply contracts are denominated in U.S. dollars, British pounds sterling or Euros. In some cases, our supplier arrangements contain inflationary adjustment provisions based on accepted industry indices, and we typically include an inflation component in estimating our supply costs. Although the raw material industry is experiencing a softening in demand, some specific materials have yet to reflect a corresponding reduction in price. We expect that raw material market pricing volatility will remain a factor that may impact our costs, despite protections in our existing supplier arrangements. We will continue to focus our strategic cost reduction plans on mitigating the effects of this potential cost increase on our operations.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

        As a result of our operating and financing activities, we are exposed to various market risks that may affect our consolidated results of operations and financial position. These market risks include fluctuations in interest rates, which impact the amount of interest we must pay on our variable rate debt.

        Other than the interest rate swaps described below, financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash investments, the funds in which our pension assets are invested, and trade accounts receivable.

        Accounts receivable include amounts billed and currently due from customers, amounts earned but unbilled, particular estimated contract changes, claims in negotiation that are probable of recovery, and amounts retained by the customer pending contract completion. For the twelve months ended December 31, 2011, approximately 85% of our net revenues were from sales to Boeing. We continuously monitor collections and payments from customers and maintain a provision for estimated credit losses as deemed appropriate based upon historical experience and any specific customer collection issues that have been identified. While such credit losses have historically not been material, we cannot guarantee that we will continue to experience the same credit loss rates in the future.

Table of Contents

        We maintain cash and cash equivalents with various financial institutions and perform periodic evaluations of the relative credit standing of those financial institutions and from time to time we invest excess cash in liquid short-term money market funds. We have not experienced any losses in such accounts and believe that we are not exposed to any significant credit risk on cash and cash equivalents. Additionally, we monitor our defined benefit pension plan asset investments on a quarterly basis and we believe that we are not exposed to any significant credit risk in these investments.

Commodity Price Risks

        Some raw materials and operating supplies are subject to price and supply fluctuations caused by market dynamics. Our strategic sourcing initiatives are focused on mitigating the impact of commodity price risk. We are party to collective raw material sourcing contracts arranged through Boeing and Airbus. These collective sourcing contracts allow us to obtain raw materials at pre-negotiated rates and help insulate us from market volatility across the industry for certain specialized metallic and composite raw materials used in the aerospace industry. Although our supply agreements with Boeing and Airbus allow us to pass on certain unusual increases in component and raw material costs to Boeing and Airbus in limited situations, we may not be fully compensated for such increased costs. We also have long-term supply agreements with a number of our major parts suppliers. We, as well as our supply base, are experiencing pricing increases for metallic raw materials (primarily aluminum and titanium) despite softening market demand across the industry. Although the demand pressure has been somewhat eased for certain metallic and composite raw materials, the specialized nature of the materials used in the aerospace industry has prevented a corresponding decrease in prices. We generally do not employ forward contracts or other financial instruments to hedge commodity price risk, although we continue to review a full range of business options focused on strategic risk management for all raw material commodities.

        Any failure by our suppliers to provide acceptable raw materials, components, kits or subassemblies could adversely affect our production schedules and contract profitability. We assess qualification of suppliers and continually monitor them to control risk associated with such supply base reliance.

        To a lesser extent, we also are exposed to fluctuations in the prices of certain utilities and services, such as electricity, natural gas, chemicals and freight. We utilize a range of long-term agreements to minimize procurement expense and supply risk in these areas.

Interest Rate Risks

        After the effect of interest rate swaps, as of December 31, 2011, we had $325.0 million of total fixed rate debt and $236.9 million of variable rate debt outstanding as compared to $400.0 million of total fixed rate debt and $166.1 million of variable rate debt outstanding as of December 31, 2010. Borrowings under our Senior Secured Credit Facility bear interest that varies with LIBOR. Interest rate changes generally do not affect the market value of such debt, but do impact the amount of our interest payments and, therefore, our future earnings and cash flows, assuming other factors are held constant. Assuming other variables remain constant, including levels of indebtedness, a one percentage point increase in interest rates on our variable debt would have an estimated impact on pre-tax earnings and cash flows for the next twelve months of approximately $2.4 million.

        We enter into floating-to-fixed interest rate swap agreements periodically. As of December 31, 2011, the interest swap agreements had notional amounts totaling $325.0 million.

(1)

The fixed rate represents the rate at which interest is paid by the Company pursuant to the terms of its interest rate swap agreements.

(2)

The effective Term B fixed interest rate represents the fixed rate of the derivative instrument plus the 175 basis point margin on the pro rata share of Term B-1 and 325 basis points margin on the pro rata share of Term B-2 above the variable LIBOR borrowing rate we pay on the Term B loan.

        The purpose of entering into these swaps was to reduce our exposure to variable interest rates. In accordance with FASB authoritative guidance the interest rate swaps are being accounted for as cash flow hedges and the fair value of the swap agreements is reported on the balance sheet as an asset, if positive, or a liability, if negative. The fair value of the interest rate swaps was a net liability of approximately $(4.8) million at December 31, 2011. The Company also considers counterparty credit risk and its own credit risk in its determination of all estimated fair values. The Company has applied these valuation techniques at year end and believes it has obtained the most accurate information available for the types of derivative contracts it holds. The Company attempts to manage exposure to counterparty credit risk by only entering into agreements with major financial institutions which are expected to be able to fully perform under the terms of the agreement. We do not use these contracts for speculative or trading purposes.

Foreign Exchange Risks

        The Company had foreign currency hedge transactions in place as of December 31, 2010 for the B767 and B777 programs. The Company did not enter into any new foreign currency hedge transactions during 2011.

        As a result of the BAE Acquisition, we have sales, expenses, assets and liabilities that are denominated in British pounds sterling. Spirit Europe's functional currency is the British pound sterling. However, sales of Spirit Europe's products to Boeing and some procurement costs are denominated in U.S. dollars and Euros. As a consequence, movements in exchange rates could cause net sales and our expenses to fluctuate, affecting our profitability and cash flows. We use foreign currency forward contracts to reduce our exposure to currency exchange rate fluctuations. The objective of these contracts is to minimize the impact of currency exchange rate movements on our operating results. We do not use these contracts for speculative or trading purposes.

        In addition, even when revenues and expenses are matched, we must translate British pound sterling denominated results of operations, assets and liabilities for our foreign subsidiaries to U.S. dollars in our consolidated financial statements. Consequently, increases and decreases in the value of the U.S. dollar as compared to the British pound sterling will affect our reported results of operations and the value of our assets and liabilities on our consolidated balance sheet, even if our results of operations or the value of those assets and liabilities has not changed in its original currency. These transactions could significantly

affect the comparability of our results between financial periods and/or result in significant changes to the carrying value of our assets, liabilities and shareholders' equity.

Includes foreign currency hedge contracts for 2012 through 2013 novated to Spirit Europe as a result of the BAE Acquisition (buy $0.0/sell £0.2), which had no underlying contractual transactions at the inception date of the contracts and, therefore, are classified as debt securities which are not subject to hedge accounting. The mark-to-market values of these debt securities are recorded through the Consolidated Statement of Operations on a monthly basis in accordance with FASB authoritative guidance on investments — debt and equity securities disclosures.

        In accordance with FASB authoritative guidance, the intercompany revolving credit facility with Spirit Europe is exposed to fluctuations in foreign exchange rates. The fluctuation in rates for 2011 resulted in a loss of $2.3 million reflected in other income/expense.

        Other than the interest rate swaps and foreign exchange contracts, we have no other derivative financial instruments.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of
Spirit AeroSystems Holdings, Inc.

        In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations and comprehensive income, of shareholders' equity and of cash flows present fairly, in all material respects, the financial position of Spirit AeroSystems Holdings, Inc. (the "Company") at December 31, 2011 and December 31, 2010, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2011 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule appearing under Item 15 presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Annual Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

1.     Nature of Business

        Spirit AeroSystems Holdings, Inc. ("Holdings" or the "Company") was incorporated in the state of Delaware on February 7, 2005, and commenced operations on June 17, 2005 through the acquisition of The Boeing Company's ("Boeing") operations in Wichita, Kansas, Tulsa, Oklahoma and McAlester, Oklahoma (the "Boeing Acquisition"). Holdings provides manufacturing and design expertise in a wide range of products and services for aircraft original equipment manufacturers and operators through its subsidiary, Spirit AeroSystems, Inc. ("Spirit"). Onex Corporation ("Onex") of Toronto, Canada and certain of its affiliates maintain majority voting power of Holdings. In April 2006, Holdings acquired the aerostructures division of BAE Systems (Operations) Limited ("BAE Aerostructures"), which builds structural components for Airbus, a division of the European Aeronautic Defense and Space NV ("Airbus") and Boeing. Prior to this acquisition, Holdings sold essentially all of its production to Boeing. Since Spirit's incorporation, the Company has expanded its customer base to include Sikorsky, Rolls-Royce, Gulfstream, Bombardier, Mitsubishi Aircraft Corporation, Southwest Airlines, Continental Airlines, and American Airlines. The Company has its headquarters in Wichita, Kansas, with manufacturing facilities in Tulsa and McAlester, Oklahoma; Prestwick, Scotland; Wichita, Kansas; Kinston, North Carolina and Subang, Malaysia. The Company also recently constructed an assembly plant for the A350 XWB aircraft in Saint-Nazaire, France, which began its operations during 2011.

        The Company is the majority participant in the Kansas Industrial Energy Supply Company ("KIESC"), a tenancy-in-common with other Wichita companies established to purchase natural gas.

        The Company participates in two joint ventures, Spirit-Progresstech LLC ("Spirit-Progresstech") and Taikoo Spirit AeroSystems Composite Co. Ltd. ("TSACCL"), of which Spirit's ownership interest is 50.0% and 31.5%, respectively. Spirit-Progresstech provides aerospace engineering support services and TSACCL was formed to develop and implement a state-of-the-art composite and metal bond component repair station in the Asia-Pacific region.

        The accompanying consolidated financial statements include the Company's financial statements and the financial statements of its majority owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and the instructions to Form 10-K. All intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to the prior year financial statements and notes to conform to the 2011 presentation.

2.     Summary of Significant Accounting Policies

Basis of Presentation

        The accompanying consolidated financial statements include the Company's financial statements and the financial statements of its majority-owned subsidiaries and have been prepared in accordance with GAAP. Investments in business entities in which the Company does not have control, but has the ability to exercise influence over operating and financial policies, including Spirit-Progresstech and TSACCL, are accounted for by the equity method. KIESC is fully consolidated as the Company owns 77.8% of the entity's equity. All intercompany balances and transactions have been eliminated in consolidation. The Company's U.K. subsidiary uses local currency, the British pound, as its functional currency; the Malaysian subsidiary uses the British pound and our Singapore subsidiary uses the Singapore dollar. All other foreign subsidiaries and branches use the U.S. dollar as their functional currency.

        As part of the monthly consolidation process, the functional currencies of the Company's international subsidiaries are translated to U.S. dollars using the end-of-month translation rate for balance sheet accounts and average period currency translation rates for revenue and income accounts.

Use of Estimates

        The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates and assumptions.

        The results of operations during fiscal 2011 include the favorable impact of cumulative catch-up adjustments relating to prior period revenues of $13.8 driven by productivity improvements, recognition of favorable performance as we closed out B737 and B777 contract blocks in the fourth quarter, and a lower forecast for our short-term incentive accrual, partially offset by increasing material costs in our Wing Systems segment.

        The results of operations during fiscal 2010 include the unfavorable impact of cumulative catch-up adjustments relating to prior period revenues of $23.2 resulting from a charge on the Hawker 850 XP contract related to the decision to exit the program, additional cost requirements to meet hardware test schedules on the Sikorsky CH-53K program, and unfavorable cost trends on the B787 program, partially offset by favorable cost performance trends on mature programs.

        The results of operations during fiscal 2009 include the unfavorable impact of cumulative catch-up adjustments relating to prior period revenues of $58.5 resulting from post-strike production ramp up as a result of the IAM strike at Boeing, nutplate rework, transition to a new enterprise resource planning (ERP) system, higher than forecasted costs on contract blocks completed in December 2009 and higher than expected costs on the Sikorsky CH-53K program.

Revenue Recognition

        A significant portion of the Company's revenues are recognized under long-term, volume-based pricing contracts, requiring delivery of products over several years. The Company recognizes revenue under the contract method of accounting and records sales and profits on each contract in accordance with the percentage-of-completion method of accounting, primarily using the units-of-delivery method. The units-of-delivery method recognizes as revenue the contract price of units of a basic production product delivered during a period and as the cost of earned revenue the costs allocable to the delivered units. Costs allocable to undelivered units are reported in the balance sheet as inventory. The method is used in circumstances in which an entity produces units of a basic product under production-type contracts in a continuous or sequential production process to buyers' specifications. Recurring long-term production contracts are usually divided into contract blocks for this purpose, with each block treated as a separate contract for "units-of-delivery" production-type contract accounting purposes.

        The total quantity of production units to be delivered under a contract may be set as a single contract accounting block, or it can be split into multiple blocks. Unless the life of the contract is so long that it prevents reliable estimates, the entire contract will typically be set as the contract accounting block quantity. "Life-of-program" or "requirements-based" contracts often lead to continuing sales of more than twenty years. Since this is much longer than can be reliably estimated, Spirit uses parameters based on the contract facts and circumstances to determine the length of the contract block. This analysis includes: considering the customer's firm orders, internal assessment of the market, reliabilities of cost estimates,

88

potential segmentation of non-recurring elements of the contract, and other factors. Contract block sizes may also be determined based on certain contractual terms such as pricing renegotiation dates, such that certain contract blocks may use an approximate date instead of a defined unit quantity in order to increase the ability to estimate accurately given that the renegotiated pricing is unknown for the planning block. Shorter contract blocks for mature, ongoing programs are common due to the presence of recent cost history and probable forecast accuracy. Mature program contract blocks tend to be approximately two years in length. Initial contract blocks often require a longer time period and a greater number of units in order to take into account the higher cost of early units due to a steeper experience curve and pre-production design costs. Initial contract blocks on newer programs can extend up to ten years. As these programs mature and efficiencies are realized, subsequent contract block length shortens to take into account the steady state of the continuing production.

        Revenues from non-recurring design work are recognized based on substantive milestones or use of the cost-to-cost method, that are indicative of our progress toward completion depending on facts and circumstances. We follow the requirements of FASB authoritative guidance on accounting for the performance of construction-type and certain production-type contracts (the contract method of accounting), and use the cumulative catch-up method in accounting for revisions in estimates. Under the cumulative catch-up method, the impacts of revisions in estimates are recognized immediately when changes in estimated contract profitability become known.

        A profit rate is estimated based on the difference between total revenues and total costs over a contract block. Total revenues at any given time include actual historical revenues up to that time plus future estimated revenues. Total costs at any given time include actual historical costs up to that time plus future estimated costs. Estimated revenues include negotiated or expected values for units delivered, estimates of probable recoveries asserted against the customer for changes in specifications, price adjustments for contract and volume changes, and escalation. Costs include the estimated cost of certain pre-production efforts (including non-recurring engineering and planning subsequent to completion of final design) plus the estimated cost of manufacturing a specified number of production units. Estimates take into account assumptions related to future labor performance and rates, and projections related to material and overhead costs including expected "learning curve" cost reductions over the term of the contract. Estimated revenues and costs also take into account the expected impact of specific contingencies that we believe are probable.

        Estimates of revenues and costs for our contract blocks span a period of multiple years and are based on a substantial number of underlying assumptions. We believe that the underlying assumptions are sufficiently reliable to provide a reasonable estimate of the profit to be generated. However, due to the significant length of time over which revenue streams will be generated, the variability of the revenue and cost streams can be significant if the assumptions change. Estimates of profit margins for contract accounting blocks are typically reviewed on a quarterly basis. Assuming the initial estimates of sales and costs under the contract block are accurate, the percentage-of-completion method results in the profit margin being recorded evenly as revenue is recognized under the contract block. Changes in these underlying estimates due to revisions in sales and cost estimates may result in profit margins being recognized unevenly over a contract block as such changes are accounted for on a cumulative basis in the period estimates are revised, which we refer to as cumulative catch-up adjustments. When the current estimates of total contract revenue and total contract cost indicate a loss, a provision for the entire loss on the contract, known as a forward-loss charge, is recorded to cost of sales in the period in which they become evident.

        For revenues not recognized under the contract method of accounting, the Company recognizes revenues from the sale of products at the point of passage of title, which is generally at the time of

89

shipment. Shipping and handling costs are included in cost of sales. Revenues earned from providing maintenance services, including any contracted research and development, are recognized when the service is complete or other contractual milestones are attained. Revenues from non-recurring design work are recognized based on substantive milestones that are indicative of our progress toward completion. Non-recurring revenues, which are derived primarily from engineering and design efforts, were $222.0, $297.0 and $328.0 for each of the twelve month periods ending December 31, 2011, December 31, 2010 and December 31, 2009, respectively.

        Since Boeing retained title to tooling assets obtained as part of the Boeing Acquisition and provides such tooling to the Company at no cost, the Company treats the amortization of Boeing-owned tooling as a reduction to revenues as required by FASB authoritative guidance related to accounting for consideration given by a vendor to a customer. The Company recognized zero and $1.9 as a reduction to net revenues for the periods ended December 31, 2011 and December 31, 2010, respectively, as a result of amortization to Boeing-owned tooling. Boeing-owned tooling became fully amortized in 2010. However, under an agreement with Airbus, certain payments that are also accounted for as consideration given by a vendor to a customer will be amortized as a reduction to revenues on units delivered beginning in early 2012.

New Programs

        A significant portion of the Company's future revenues is expected to be derived from new programs, most notably the B787, on which we may be contracted to provide design and engineering services, recurring production, or both. There are several risks inherent to such new programs. In the design and engineering phase, we may incur costs in excess of our forecasts due to several factors, including cost overruns, customer directed change orders and delays in the overall program. We may also incur higher than expected recurring production costs, which may be caused by a variety of factors, including the future impact of engineering changes (or other change orders) or our inability to secure contracts with our suppliers at projected cost levels. Our ability to recover these excess costs from the customer will depend on several factors, including our rights under our contracts for the new programs. In determining our profits and losses in accordance with the percentage-of-completion method of contract accounting, we are required to make significant assumptions regarding our future costs, as well as the estimated number of units to be manufactured under the contract and other variables. We continually review and update our assumptions based on market trends and our most recent experience. If we make material changes to our assumptions, such as a reduction in the estimated number of units to be produced under the contract (which could be caused by emerging market trends or other factors), an increase in future production costs or a change in the recoverability of increased design or production costs, we may experience negative cumulative catch-up adjustments related to revenues previously recognized. In some cases, we may recognize forward-loss amounts.

Research and Development

        Research and development includes costs incurred for experimentation, design and testing and are expensed as incurred as required under FASB authoritative guidance pertaining to accounting for research and development costs.

Joint Venture

        The value of the Company's 50.0% ownership interest in Spirit-Progresstech LLC totaled $2.4 at December 31, 2011 and is accounted for under the equity method of accounting.

90

Table of Contents

Spirit AeroSystems Holdings, Inc.

Notes to the Consolidated Financial Statements — (Continued)
($, €, £, and RM in millions other than per share amounts)

        The value of the Company's 31.5% ownership interest in Taikoo Spirit AeroSystems Composite Co. Ltd. totaled $2.1 at December 31, 2011 and is accounted for under the equity method of accounting.

Cash and Cash Equivalents

        Cash and cash equivalents represent all highly liquid investments with original maturities of three months or less.

Accounts Receivable

        Accounts receivable are recorded at the invoiced amount and do not bear interest. Consistent with industry practice, the Company classifies unbilled receivables related to contracts accounted for under the long-term contract method of accounting, as current. The Company determines an allowance for doubtful accounts based on a review of outstanding receivables. Account balances are charged off against the allowance after the potential for recovery is considered remote. The Company's allowance for doubtful accounts was approximately $1.4 and zero at December 31, 2011 and December 31, 2010, respectively.

        Accounts receivable, net includes unbilled receivables on long-term aerospace contracts, comprised principally of revenue recognized on contracts for which amounts were earned but not contractually billable as of the balance sheet date, or amounts earned in which the recovery will occur over the term of the contract, which could exceed one year.

Inventory

        Raw materials are stated at lower of cost (principally on an actual or average cost basis) or market. Inventoried costs attributed to units delivered under long-term contracts are based on the estimated average cost of all units expected to be produced and are determined under the learning curve concept which anticipates a predictable decrease in unit costs as tasks and production techniques become more efficient through repetition. This usually results in an increase in inventory (referred to as "excess-over-average" or "deferred production costs") during the early years of a contract. These costs are deferred only to the extent the amount of actual or expected excess-over-average is reasonably expected to be fully offset by lower-than-average costs in future periods of a contract. If in-process inventory plus estimated costs to complete a specific contract exceed the actual plus anticipated remaining sales value of such contract, such excess is charged to cost of sales in the period the loss becomes known, thus reducing inventory to estimated realizable value. Costs in inventory include amounts relating to contracts with long production cycles, some of which are not expected to be realized within one year.

        The Company reviews its general stock materials and spare parts inventory each quarter to identify impaired inventory, including excess or obsolete inventory, based on historical sales trends and expected production usage. Impaired inventories are written off to work-in-process in the period identified.

        Work-in-process inventory includes deferred production costs for the excess of production costs over the estimated average cost per ship set, and credit balances for favorable variances on contracts between actual costs incurred and the estimated average cost per ship set for units delivered under the current production blocks. Recovery of excess over average deferred production costs is dependent on the number of ship sets ultimately sold and the ultimate selling prices and lower production costs associated with future production under these contract blocks. Work-in-process inventory also includes non-recurring production costs. Non-recurring production costs include design and engineering costs and test articles.

($, €, £, and RM in millions other than per share amounts)

        Finished goods inventory is stated at its estimated average per unit cost based on all units expected to be produced.

        Capitalized pre-production costs include certain contract costs, including applicable overhead, incurred before a product is manufactured on a recurring basis. Significant customer-directed work changes can also cause pre-production costs to be incurred. These costs are typically recovered over a certain number of ship set deliveries.

Property, Plant and Equipment

        Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is applied using a straight-line method over the useful lives of the respective assets as described in the following table:

        We capitalize certain costs, such as software coding, installation and testing, that are incurred to purchase or to create and implement internal-use computer software in accordance with FASB authoritative guidance pertaining to capitalization of cost for internal-use software. Our capitalization policy includes specifications that the software must have a service life greater than one year, is legally and substantially owned by Spirit, and has an acquisition cost of greater than $0.1.

        In January 2010, we adopted a change in accounting estimate which extended the useful lives of certain assets. The effect of this change was a $14.6 decrease in depreciation capitalized to inventory for the twelve-month period ended December 31, 2010, which will eventually flow through cost of sales following the process for contract accounting.

Intangible Assets and Goodwill

        Intangible assets are recorded at estimated fair value and are comprised of patents, favorable leasehold interests, and customer relationships that are amortized on a straight-line basis over their estimated useful lives, ranging from 6 to 16 years for patents, 14 to 24 years for favorable leasehold interests, and 8 years for customer relationships.

Impairment or Disposal of Long-Lived Assets and Goodwill

        Spirit reviews capital and amortizing intangible assets (long-lived assets) for impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable in accordance with FASB authoritative guidance on accounting for the impairment or disposal of long-lived assets. Under the standard, assets must be classified as either held-for-use or available-for-sale. An impairment loss is recognized when the carrying amount of an asset that is held for use exceeds the projected undiscounted future net cash flows expected from its use and disposal, and is measured as the amount by which the carrying amount of the asset exceeds its fair value, which is measured by discounted cash flows when quoted market prices are not available. For assets

Notes to the Consolidated Financial Statements — (Continued)
($, €, £, and RM in millions other than per share amounts)

available-for-sale, an impairment loss is recognized when the carrying amount exceeds the fair value less cost to sell. The Company performs an annual impairment test for goodwill in the fourth quarter of each year, in accordance with FASB authoritative guidance pertaining to goodwill and other intangible assets, or more frequently, if an event occurs or circumstances change that would more likely than not reduce fair value below current value.

Deferred Financing Costs

        Costs relating to long-term debt are deferred and included in other long-term assets. These costs are amortized over the term of the related debt or debt facilities, and are included as a component of interest expense.

Derivative Instruments and Hedging Activity

        We use derivative financial instruments to manage the economic impact of fluctuations in currency exchange rates and interest rates. To account for our derivative financial instruments, we follow the FASB guidance on accounting for derivatives and hedges. Derivative financial instruments are recognized on the Consolidated Balance Sheets as either assets or liabilities and are measured at fair value. Changes in fair value of derivatives are recorded each period in earnings or accumulated other comprehensive income, depending on whether a derivative is effective as part of a hedge transaction, and if it is, the type of hedge transaction. Gains and losses on derivative instruments reported in other comprehensive income are subsequently included in earnings in the periods in which earnings are affected by the hedged item or when the hedge is no longer effective. We present the cash flows associated with our derivatives as a component of the operating or investing sections of the statement of cash flows. Our use of derivatives has generally been limited to interest rate swaps and foreign currency forward contracts. The Company enters into foreign currency forward contracts to reduce the risks associated with the changes in foreign operating or exchange rates on sales and cost of sales denominated in currencies other than the entities' functional currency.

Fair Value of Financial Instruments

        Financial instruments are measured in accordance with FASB authoritative guidance related to fair value measurements. This guidance clarifies the definition of fair value, prescribes methods for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value, and expands disclosures about fair value measurements. See Note 9, Fair Value Measurements. The three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies, is:

        Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets.

        Level 3 — Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

Income Taxes

        Income taxes are accounted for in accordance with FASB authoritative guidance on accounting for income taxes. Deferred income tax assets and liabilities are recognized for the future income tax consequences attributable to differences between the financial statement carrying amounts for existing assets and liabilities and their respective tax bases. A valuation allowance is recorded to reduce deferred income tax assets to an amount that in management's opinion will ultimately be realized. Tax rate changes impacting these assets and liabilities are recognized in the period during which the rate change occurs.

        We record an income tax expense or benefit based on the net income earned or net loss incurred in each tax jurisdiction and the tax rate applicable to that income or loss. In the ordinary course of business, there are transactions for which the ultimate tax outcome is uncertain. These uncertainties are accounted for in accordance with FASB authoritative guidance on accounting for the uncertainty in income taxes. The final tax outcome for these matters may be different than management's original estimates made in determining the income tax provision. A change to these estimates could impact the effective tax rate and net income or loss in subsequent periods. We use the flow-through accounting method for tax credits. Under this method, tax credits reduce income tax expense.

Stock-Based Compensation and Other Share-Based Payments

        Many of the Company's employees are participants in various stock compensation plans. The Company accounts for stock option plans, restricted share plans and other stock-based payments in accordance with FASB authoritative guidance pertaining to share-based payment. The expense attributable to the Company's employees is recognized over the period the amounts are earned and vested, as described in Note 15.

Service and Product Warranties and Extraordinary Rework

        Provisions for estimated expenses related to service and product warranties and certain extraordinary rework are made at the time products are sold. These estimates are established using historical information on the nature, frequency and average cost of warranty claims.

        The following is a roll forward for the warranty and extraordinary rework provision as of December 31, 2011 and December 31, 2010:

During 2011, we expensed an additional $9.0 to charges and unallocated cost of sales due to changes in claims data and historical experience.

New Accounting Pronouncements

        In December 2011, the FASB issued Accounting Standards Update 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities (FASB ASU 2011-11). The amendments in this update will require an entity to disclose information about offsetting and related arrangements to

enable users of its financial statements to understand the effect of those arrangements on its financial position. The intention is to enhance required disclosures by improving information about financial instruments and derivative instruments that are either offset in accordance with FASB guidance or are subject to an enforceable master netting arrangement; irrespective of whether they are offset in accordance with FASB guidance. The provisions of FASB ASU 2011-11 are effective for annual reporting periods beginning on or after January 1, 2013. The adoption of the provisions of FASB ASU 2011-11 is not expected to have a material impact on the Company's consolidated financial statements.

        In September 2011, the FASB issued Accounting Standards Update 2011-08, Intangibles — Goodwill and Other — (Topic 350) Testing Goodwill for Impairment (FASB ASU 2011-08). The amendments in this update will allow an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under these amendments, an entity would not be required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendments include a number of events and circumstances for an entity to consider in conducting the qualitative assessment. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted, including for annual and interim goodwill impairment tests performed as of a date before September 15, 2011, if an entity's financial statements for the most recent annual or interim period have not yet been issued or, for nonpublic entities, have not yet been made available for issuance. Adoption of the provisions of FASB ASU 2011-8 did not have a material impact on the Company's consolidated financial statements.

        In September 2011, the FASB issued Accounting Standards Update 2011-09, Compensation — Retirement Benefits — Multiemployer Plans (Subtopic 715-80) Disclosures about an Employer's Participation in a Multiemployer Plan (FASB ASU 2011-09). The amendments in this update require additional disclosures about an employer's participation in a multiemployer plan. For public entities, the amendments in this update are effective for annual periods for fiscal years ending after December 15, 2011, and thus were effective for Spirit for the twelve months ended December 31, 2011. The amendments should be applied retrospectively for all prior periods presented. Adoption of the provisions of FASB ASU 2011-09 did not have a material impact on the Company's consolidated financial statements.

        In June 2011, the FASB issued Accounting Standards Update 2011-05, Presentation of Comprehensive Income ("FASB ASU 2011-05"), which gives an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. This update eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. The amendments in this update do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The provisions of FASB ASU 2011-05 are effective for interim periods and fiscal years beginning after December 15, 2011, with early adoption permitted. Adoption of the provisions of FASB ASU 2011-05 did not have a material impact on the Company's consolidated financial statements.

        In May 2011, the FASB issued Accounting Standards Update 2011-04 Fair Value Measurements (Topic 820) — Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRSs, ("FASB ASU 2011-04"). This update will require disclosures regarding transfers between Level 1 and Level 2 of the fair value hierarchy, disclosures about the sensitivity of a fair value measurement categorized within Level 3 of the fair value hierarchy, and the categorization by level of the

fair value hierarchy for items that are not measured at fair value in the statement of financial position, but for which the fair value of such items is required to be disclosed. FASB ASU 2011-04 will be effective during interim and annual periods beginning after December 15, 2011. Early adoption is not permitted. The adoption of the provisions of FASB ASU 2011-04 is not expected to have a material impact on the Company's consolidated financial statements

        In April 2010, the FASB issued Accounting Standards Update 2010-17, Revenue Recognition — Milestone Method (Topic 605) ("FASB ASU 2010-17"), which provides guidance on applying the milestone method of revenue recognition in arrangements with research and development activities. The amendments in this update are effective on a prospective basis for milestones achieved in fiscal years and interim periods within those years, beginning on or after June 15, 2010 and thus were effective for the Company's fiscal quarter ended March 31, 2011. Adoption of the provisions of FASB ASU 2010-17 did not have a material impact on the Company's consolidated financial statements.

        Capitalized pre-production costs include certain contract costs, including applicable overhead, incurred before a product is manufactured on a recurring basis. Significant unfunded statement of work changes can also cause pre-production costs to be incurred. These costs are typically recovered over a certain number of ship set deliveries and the Company believes these amounts will be fully recovered.

        The following is a roll forward of the capitalized pre-production costs, net of forward-loss, included in the inventory balance at December 31, 2011:

        Capitalized pre-production costs, net of forward-losses, included in inventory are summarized as follows:

        Work-in-process inventory includes deferred production costs for the excess of production costs over the estimated average cost per ship set, and credit balances for favorable variances on contracts between actual costs incurred and the estimated average cost per ship set for units delivered under the current production blocks. Recovery of excess-over-average deferred production costs is dependent on the number of ship sets ultimately sold and the ultimate selling prices and lower production costs associated with future production under these contract blocks. The Company believes these amounts will be fully recovered.

        Sales significantly under estimates or costs significantly over estimates could result in the realization of losses on these contracts in future periods.

        The following is a roll forward of the carrying amount of goodwill at December 31, 2011:

7.     Advance Payments and Deferred Revenue/Credits

        Advance payments.    Advance payments are those payments made to Spirit by third parties in contemplation of the future performance of services, receipt of goods, incurrence of expenditures, or for other assets to be provided by Spirit on a contract and are repayable if such obligation is not satisfied. The amount of advance payments to be recovered against units expected to be delivered within a year is classified as a short-term liability, with the balance of the unliquidated advance payments classified as a long-term liability.

        Deferred revenue/credits.    Deferred revenue/credits generally consists of nonrefundable amounts received in advance of revenue being earned for specific contractual deliverables. These payments are classified as deferred revenue/credits when received and recognized as revenue as the production units are delivered. In the fourth quarter of 2010, as part of a memorandum of agreement with Boeing related to the B787 contract, a payment of $236.2 was recorded as current deferred revenue/credits. A formal amendment implementing the terms of the memorandum of agreement was finalized and the related revenue recognized in the second quarter of 2011, as the terms related to prior performance.

        Advance payments and deferred revenue/credits are summarized by platform as follows:

8.     Government Grants

        We received grants in the form of government funding for a portion of the site construction and other specific capital asset cost at our Kinston, North Carolina and Subang, Malaysia sites. Deferred grant income is being amortized as a reduction to production cost. This amortization is based on specific terms associated with the different grants. In North Carolina, the deferred grant income related to the capital investment criteria, which represents half of the grant, is being amortized over the lives of the assets purchased to satisfy the capital investment performance criteria. The other half of the deferred grant income is being amortized over a ten-year period in a manner consistent with the job performance criteria. In Malaysia, the deferred grant income is being amortized based on the lives of the eligible assets constructed with the grant funds as there are no performance criteria. As of December 31, 2011, the value recorded within property, plant and equipment related to the use of grant funds in North Carolina and

Malaysia was $143.6, prior to amortization, including foreign exchange rate changes. For the twelve months ended December 31, 2010, $8.9 recorded within property, plant and equipment represented transactions where funds have been paid directly to contractors by an agency of the Malaysian Government in the case of Malaysia, and by the escrow agent in North Carolina, so they are not reflected on our consolidated statements of cash flows. There were no such payments for the twelve months ended December 31, 2011.

9.     Fair Value Measurements

        FASB's authoritative guidance on fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. It also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance discloses three levels of inputs that may be used to measure fair value:

103

Table of Contents

Spirit AeroSystems Holdings, Inc.

Notes to the Consolidated Financial Statements — (Continued)
($, €, £, and RM in millions other than per share amounts)

 

        The fair value of the interest rate swaps and foreign currency hedge contracts are determined by using mark-to-market reports generated for each derivative and evaluated for counterparty risk. In the case of the interest rate swaps, the Company evaluated its counterparty risk using credit default swaps, historical default rates and credit spreads.

        The Company's long-term debt consists of a senior secured term loan, senior unsecured notes, and the Malaysia term loan. The estimated fair value of our debt obligations is based on the quoted market prices for such obligations. The following table presents the carrying amount and estimated fair value of long-term debt in accordance with FASB authoritative guidance on fair value measurements related to disclosures of financial instruments:

        See Investments Footnote 11 for Fair Value disclosure on government and corporate debt securities.

10.   Derivative and Hedging Activities

        The Company enters into interest rate swap agreements to reduce its exposure to the variable rate portion of its long-term debt. The Company also enters into foreign currency hedge contracts to reduce the

104

risks associated with the changes in foreign exchange rates on sales and cost of sales denominated in currencies other than the entities' functional currency. Any gains or losses on the hedges are included in earnings when the underlying transaction that was hedged occurs. The Company does not use these contracts for speculative or trading purposes. On the inception date, the Company designates a derivative contract as either a fair value or cash flow hedge in accordance with FASB guidance on accounting for derivatives and hedges and links the contract to either a specific asset or liability on the balance sheet, or to forecasted commitments or transactions. The Company formally documents the hedging relationship between the hedging instrument and the hedged item, as well as its risk-management objective and strategy for undertaking the hedge, the nature of the risk being hedged, how the hedging instrument's effectiveness in offsetting the hedged risk will be assessed and a description of the method of measuring ineffectiveness. The Company also formally assesses, both at the hedge's inception and on a quarterly basis, whether the derivative item is effective in offsetting changes in fair value or cash flows.

        Changes in the fair value of derivative instruments considered to be effective hedges are reported in accumulated other comprehensive income, net of tax. In the case of interest rate swaps, amounts are subsequently reclassified into interest expense as a yield adjustment of the hedged interest payments in the same period in which the related interest affects earnings. If the actual interest rate on the fixed rate portion of debt is less than LIBOR, the monies received are recorded as an offset to interest expense. Conversely, if the actual interest rate on the fixed rate portion of debt is greater than LIBOR, then the Company pays the difference, which is recorded to interest expense. Reclassifications of the amounts related to the foreign currency hedge contracts are recorded to earnings in the same period in which the underlying transaction occurs. Any change in the fair value resulting from ineffectiveness is immediately recognized in earnings.

        The Company also considers counterparty credit risk and its own credit risk in its determination of all estimated fair values. The Company has applied these valuation techniques as of December 31, 2011 and believes it has obtained the most accurate information available for the types of derivative contracts it holds. The Company attempts to manage exposure to counterparty credit risk by only entering into agreements with major financial institutions which are expected to be able to fully perform under the terms of the agreement.

        The Company discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item; the derivative expires or is sold, terminated or exercised; the derivative is no longer designated as a hedging instrument because it is unlikely that a forecasted transaction will occur; or management determines that the designation of the derivative as a hedging instrument is no longer appropriate. When hedge accounting is discontinued, the Company continues to carry the derivative instrument on the balance sheet at its fair value with subsequent changes in fair value included in earnings, and gains and losses that were accumulated in other comprehensive income are recognized immediately in earnings to the extent the forecasted transaction is not expected to occur, or when the underlying transaction settles.

        To the extent that derivative instruments do not qualify for hedge accounting treatment, the changes in fair market value of the instruments are reported in the results of operations for the current period.

        The Company enters into master netting arrangements for its derivatives to mitigate the credit risk of financial instruments.

($, €, £, and RM in millions other than per share amounts)

        The Company's hedge agreements do not include provisions requiring collateral. The Company has certain derivative instruments covered by master netting arrangements whereby, in the event of a default as defined by the senior secured credit facility or termination event, the non-defaulting party has the right to offset any amounts payable against any obligation of the defaulting party under the same counterparty agreement.

        The entire asset classes of the Company, including hedges, are pledged as collateral for both the term loan and the revolving credit facility under the Company's senior secured credit facility (see Note 12, Debt).

Interest Rate Swaps

        We enter into floating-to-fixed interest rate swap agreements periodically. As of December 31, 2011, the interest rate swap agreements had notional amounts totaling $325.0.

---

(1)

The fixed rate represents the rate at which interest is paid by the Company pursuant to the terms of its interest rate swap agreements.

(2)

The effective Term B fixed interest rate represents the fixed rate of the derivative instrument plus the 175 basis-point margin on the pro rata share of Term B-1 and 325 basis-point margin on the pro rata share of Term B-2 above the variable LIBOR borrowing rate we pay on the Term B loan.

        The purpose of entering into these swaps was to reduce the Company's exposure to variable interest rates. The interest rate swaps settle on a monthly basis when interest payments are made. These settlements occur through the maturity date. The interest rate swaps are being accounted for as cash flow hedges in accordance with FASB authoritative guidance. The fair value of the interest rate swaps was a liability (unrealized loss) of ($4.8) and ($9.3) at December 31, 2011 and December 31, 2010, respectively.

Foreign Currency Forward Contracts

        Spirit's wholly-owned subsidiary Spirit AeroSystems (Europe) Limited ("Spirit Europe") has certain sales, expenses, assets and liabilities that are denominated in British pounds sterling. However, certain sales of Spirit Europe's products and some procurement costs are denominated in U.S. dollars and Euros. As a consequence, movements in exchange rates could cause net sales and our expenses to fluctuate, affecting our profitability and cash flows. In addition, even when revenues and expenses are matched, we must translate British pound sterling denominated results of operations, assets and liabilities for our foreign subsidiaries to U.S. dollars in our consolidated financial statements. Consequently, increases and decreases in the value of the U.S. dollar as compared to the British pound sterling will affect our reported results of operations and the value of our assets and liabilities on our consolidated balance sheet, even if our results of operations or the value of those assets and liabilities has not changed in its original currency. These transactions could significantly affect the comparability of our results between financial periods and/or result in significant changes to the carrying value of our assets, liabilities and shareholders' equity.

        We use foreign currency hedge contracts to reduce our exposure to currency exchange rate fluctuations, which include hedging contracts to hedge U.S. dollar revenue from certain customers. The objective of these contracts is to minimize the impact of currency exchange rate movements on our operating results. The hedges are being accounted for as cash flow hedges in accordance with FASB authoritative guidance. Gains and losses from these cash flow hedges are recorded to other comprehensive income until the underlying transaction for which the hedge was placed occurs and then the value in other comprehensive income is reclassified to earnings. The exception to the aforementioned treatment of realized gains/losses involves certain cash payments to Airbus, payable in British pounds sterling which were hedged, and this amount in other comprehensive income was reclassified into other assets when the underlying transaction occurred and will be amortized over the first A350 XWB contract block. The amount of unamortized loss reclassified out of other comprehensive income into other assets for the three months ended December 31, 2011 was zero and for the twelve months ended December 31, 2011 was ($1.1) before tax, or ($0.7) after tax. The fair value of the forward contracts was a net liability of ($0.4) as of December 31, 2011.

Notional Amount

Includes foreign currency hedge contracts for 2012 through 2013 novated to Spirit Europe as a result of the acquisition of BAE Aerostructures on April 1, 2006, which had no underlying contractual transactions at the inception date of the contracts and, therefore, are classified as net debt securities which are not subject to hedge accounting. The mark-to-market values of these net debt securities are recorded through the consolidated statement of operations on a monthly basis in accordance with FASB authoritative guidance on investments — debt and equity securities disclosures.

($, €, £, and RM in millions other than per share amounts)

        The impact on earnings from foreign currency hedge contracts that do not qualify as cash flow hedges was not material for the twelve months ended December 31, 2011 and December 31, 2010.

        Gains and losses accumulated in OCI for interest rate swaps are reclassified into earnings as each interest rate period is reset. During the next twelve months, the Company estimates that a loss of ($1.6) will be reclassified from OCI, net of tax, as a charge to earnings from interest rate swaps. Interest rate swaps are placed for a period of time not to exceed the maturity of the Company's senior secured term loan. None of the gains or losses reclassified to earnings were attributable to the discontinuance of cash flow hedges.

        Gains and losses accumulated in OCI for foreign currency hedge contracts are reclassified into earnings as the underlying transactions for which the contracts were entered into are realized. During the next twelve months, the Company estimates that a loss of ($0.1) will be reclassified from OCI, net of tax. None of the gains or losses reclassified to earnings are attributable to the discontinuance of cash flow hedges.

11.   Investments

        The amortized cost and approximate fair value of held-to-maturity securities are as follows:

        Maturities of held-to-maturity securities at December 31, 2011 are as follows:

        At December 31, 2011 and December 31, 2010, the fair value of certain investments in debt and marketable securities are less than their historical cost. Total fair value of these investments at December 31, 2011 and December 31, 2010, was $1.8 and $1.2, respectively, which is approximately 53% and 34% of the Company's held-to-maturity investment portfolio. These declines primarily resulted from decreases in market interest rates and failure of certain investments to maintain consistent credit quality ratings or meet projected earnings targets.

        Based on evaluation of available evidence, including changes in market interest rates, credit rating information and information obtained from regulatory filings, management believes the declines in fair value for these securities are temporary.

        Should the impairment of any of these securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the permanent impairment is identified.

12.   Debt

        Total debt shown on the balance sheet is comprised of the following:

Senior Secured Term Loan

        We are a party to a credit agreement that consists of a senior secured term loan and a senior secured revolving line of credit. On October 15, 2010, we entered into Amendment No. 3 to the credit agreement. As a result of the amendment, among other things, the revolving credit commitment was increased from $408.8 to $650.0 and the maturity date of the revolving credit commitment was extended to September 30, 2014. The credit agreement amendment also extended the maturity date for $437.4 (Term B-2) of the outstanding term loan to September 30, 2016. The maturity date for the $130.2 (Term B-1) balance of the outstanding term loan remained at September 30, 2013. Substantially all of Spirit's assets, including inventory and property, plant and equipment are pledged as collateral for both the term loan and the revolving credit facility. As of December 31, 2011 and December 31, 2010, the outstanding balance of the term loan was $561.9 and $566.2, respectively. Amounts outstanding under the revolving credit facility were zero at December 31, 2011 and December 31, 2010. As of December 31, 2011, there were $19.9 of letters of credit outstanding under the revolving credit agreement.

        The Company can borrow funds on its revolving credit agreement as either (i) a Eurodollar Loan, based on LIBOR or, (ii) an Alternate Base Rate (ABR) Loan, based on a rate defined in our credit agreement, plus an applicable margin as set forth in the table below:

        At December 31, 2011, the Company's total leverage ratio was 2.44:1.0 resulting in applicable margins of 3.50% and 2.50% on Eurodollar and ABR Loans respectively.

        In addition to paying interest on outstanding principal under the senior secured credit facility, Spirit is required to pay an unused line fee of 75 basis points on the unused portion of the commitments under the revolving credit facility. Spirit is required to pay participation fees equal to the applicable margin for LIBOR rate revolving credit borrowings with respect to letters of credit issued under the revolving credit facility. Spirit is also required to pay to the issuing banks under its senior secured credit facility letter of

credit fronting fees in respect of letters of credit equal to 25 basis points per year, and to the administrative agent thereunder customary administrative fees.

        The credit agreement contains customary affirmative and negative covenants, including restrictions on indebtedness, liens, type of business, acquisitions, investments, sales or transfers of assets, payments of dividends, transactions with affiliates, change in control and other matters customarily restricted in such agreements. The credit agreement also contains the following financial covenants (as defined in the credit agreement) through the final maturity date of the credit agreement:

        The Financial Covenant ratios are calculated as of the last day of each fiscal quarter. Failure to meet these financial covenants would be an event of default under the credit agreement. As of December 31, 2011, we were and expect to remain in full compliance with all covenants contained within our credit agreement for the foreseeable future.

Senior Notes

        On November 18, 2010, we issued $300.0 aggregate of 6.75% Senior Notes due December 15, 2020 (the "2020 Notes"), with interest payable, in cash in arrears, on June 15 and December 15 of each year, beginning June 15, 2011. The 2020 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by the Company and Spirit's existing and future domestic subsidiaries that guarantee Spirit's obligations under Spirit's senior secured credit facility. The carrying value of the 2020 Notes was $300.0 as of December 31, 2011.

        On September 30, 2009, we issued $300.0 of 7.50% Senior Notes due October 1, 2017 (the "2017 Notes"), with interest payable, in cash in arrears, on April 1 and October 1 of each year, beginning April 1, 2010. The 2017 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by the Company and Spirit's existing and future domestic subsidiaries that guarantee Spirit's obligations under Spirit's senior secured credit facility. The carrying value of the 2017 Notes was $294.9 as of December 31, 2011.

        As of December 31, 2011, we were and expect to remain in full compliance with all covenants contained in the indentures governing the 2020 Notes and the 2017 Notes for the foreseeable future.

Malaysian Term Loan

        On June 2, 2008, the Company's wholly-owned subsidiary, Spirit AeroSystems Malaysia SDN BHD entered into a Facility Agreement ("Facility Agreement") for a term loan facility for Ringgit Malaysia RM 69.2 (approximately USD $20.0 equivalent) (the "Malaysia Facility"), with the Malaysian Export-Import Bank. The facility requires quarterly principal repayments of RM 3.3 (USD $1.0) from September 2011 through May 2017 and quarterly interest payments payable at a fixed interest rate of 3.50% per annum. The Malaysia Facility loan balance as of December 31, 2011 was $16.1.

France Factory

        On July 17, 2009, the Company's indirect wholly-owned subsidiary, Spirit AeroSystems France SARL ("Spirit France") entered into a capital lease agreement for €9.0 (approximately USD $13.1 equivalent) with a subsidiary of BNP Paribas Bank to be used towards the construction of an aerospace-related

component assembly plant in Saint-Nazaire, France (the "Saint-Nazaire Project"). Lease payments are variable, subject to the three-month Euribor rate plus 2.20%. Lease payments are due quarterly through April 2025. As of December 31, 2011, the Saint-Nazaire capital lease balance was $11.4.

Lease Commitment

        In September 2011, the Company entered into a lease agreement for a building in Kinston, North Carolina. As part of the lease agreement, the Company's landlord agreed to certain renovations to the facility to convert the space from a warehouse to a manufacturing facility. The Company may be responsible for a portion of the construction costs and has been deemed as the owner of the building during the construction period under the FASB authoritative guidance on accounting for lessee involvement in asset construction. A total of $5.6 has been capitalized to record the facility on the Company's books with an offsetting credit to the lease financing liability.

        At the completion of the construction of the initial renovations in early 2012, the lease will be reviewed for potential sale-leaseback treatment in accordance with the FASB authoritative guidance on accounting for lessee involvement in asset construction. If sale-leaseback treatment is applicable, the amount capitalized and the corresponding liability will be reversed. If however, sale-leaseback accounting is not applicable, the building and associated lease financing liability would remain on the Company's books, the lease financing liability would be amortized over the lease term based on the payments designated in the agreement and the building would be depreciated on a straight line basis over the lease term.

13.   Pension and Other Post-Retirement Benefits

Multi-employer Pension Plan

        In connection with the collective bargaining agreement signed with the International Association of Machinists and Aerospace Workers (IAM), the Company contributes to a multi-employer defined benefit pension plan (IAM National Pension Fund). The level of contribution, as specified in the bargaining agreement was $1.35 per hour of employee service for a maximum of 80 hours per bi-weekly pay period through June 30, 2010. Effective July 1, 2010 the contribution per the collective bargaining agreement is $1.50 per hour of employee service for a maximum of 80 hours per bi-weekly pay period. The IAM bargaining agreement provides for a $0.05 increase per hour in the contribution rate beginning on July 1, 2011, with an additional $0.05 increase effective July 1 of each year through 2019.

        The collective bargaining agreement with the UAW requires the Company to contribute a specified amount per hour of service to a multi-employer defined benefit pension plan (IAM National Pension Fund). The specified amount was $1.30 in 2009 and $1.35 in 2010. Per the newly negotiated UAW collective bargaining agreement, the pension contributions will be as follows:

Effective 1/1/2011 — $1.45
Effective 1/1/2012 — $1.50
Effective 1/1/2014 — $1.55
Effective 1/1/2016 — $1.60
Effective 1/1/2018 — $1.65
Effective 1/1/2019 — $1.70
Effective 1/1/2020 — $1.75

($, €, £, and RM in millions other than per share amounts)

        The risk of this multi-employer plan is different from single-employer plans in the following aspects:

1.

Assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers.



2.

If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.



3.

If the Company chooses to stop participating in the multi-employer plan, the Company may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

        The following table summarizes the multi-employer plan to which the Company contributes:

Defined Contribution Plans

        The Company contributes to a defined contribution plan available to all U.S. employees, excluding IAM and UAW represented employees. Under the plan, the Company makes a matching contribution of 75% of the employee contribution to a maximum 8% of eligible individual employee compensation. In addition, non-matching contributions based on an employee's age and service are paid at the end of each calendar year for certain employee groups.

        The Company recorded $38.4, $37.0 and $36.3 in contributions to these plans for the twelve months ended December 31, 2011, December 31, 2010 and December 31, 2009, respectively.

        On April 1, 2006, as part of the acquisition of BAE Aerostructures, the Company established a defined contribution pension plan for those employees who are hired after the date of acquisition. Under the plan, the Company contributes 8% of basic salary while participating employees are required to contribute 4% of basic salary. The Company recorded $0.7 in contributions to this plan for the period ended December 31, 2011, $0.6 in contributions for the period ended December 31, 2010 and $0.8 in contributions for the period ended December 31, 2009.

Defined Benefit Pension Plans

        Effective June 17, 2005, pension assets and liabilities were spun-off from three Boeing qualified plans into four qualified Spirit AeroSystems plans for each Spirit employee who did not retire from Boeing by August 1, 2005. Effective December 31, 2005, all four qualified plans were merged together. In addition, Spirit has one nonqualified plan providing supplemental benefits to executives (SERP) who transferred from a Boeing nonqualified plan to a Spirit AeroSystems plan and elected to keep their benefits in this plan. Both plans are frozen as of the date of the Boeing Acquisition (i.e., no future service benefits are

being earned in these plans). We intend to fund our qualified pension plan through a trust. Pension assets are placed in trust solely for the benefit of the pension plans' participants and are structured to maintain liquidity that is sufficient to pay benefit obligations.

        On April 1, 2006, as part of the acquisition of BAE Aerostructures, the Company established a defined benefit pension plan for those employees that had pension benefits remaining in BAE Systems' pension plan. The plan is not open to new participants. The liability to the Company represents the cost of providing benefits in line with salary increases to the extent that future salary increases exceed the inflation adjustments applied to the benefits within the BAE Systems plan. BAE Systems will provide increases to past service benefits in line with inflation, subject to a maximum of 5% per annum compounded, and the Company's plan is responsible for funding the difference between the BAE Systems increases and actual salary increases. In addition, this plan provides future service benefit accruals for covered employees.

Other Post-Retirement Benefit Plans

        We also have post-retirement health care coverage for eligible U.S. retirees and qualifying dependents prior to age 65. Eligibility for employer-provided benefits is limited to those employees who were employed at the date of acquisition (Spirit) and retire on or after attainment of age 62 and 10 years of service. Employees who do not satisfy these eligibility requirements can retire with post-retirement medical benefits at age 55 and 10 years of service, but they must pay the full cost of medical benefits provided.

Obligations and Funded Status

        The following tables reconcile the funded status of both pension and post-retirement medical benefits to the balance on the consolidated balance sheets for the fiscal years 2011 and 2010. Benefit obligation balances presented in the tables reflect the projected benefit obligation (PBO) and accumulated benefit obligation (ABO) for our pension plans, and accumulated post-retirement benefit obligations (APBO) for our post-retirement medical plan. We use an end of fiscal year measurement date of December 31 for our U.S. pension and post-retirement medical plans as required by FASB authoritative guidance.

Annual Expense

        The components of pension and other post-retirement benefit plans expense for the U.S. plans and the assumptions used to determine benefit obligations for 2011, 2010 and 2009 are as follows:

        The estimated net (gain) loss that will be amortized from other comprehensive income into net periodic benefit cost over the next fiscal year for Pension Benefits is $5.5 and for Other Post-Retirement Benefits plans is $1.3.

        The components of the pension benefit plan expense for the U.K. plans and the assumptions used to determine benefit obligations for 2011, 2010 and 2009 are as follows:

        The estimated net (gain) loss that will be amortized from other comprehensive income into net periodic benefit cost over the next fiscal year for the U.K. plan is zero.

Assumptions

        The Company sets the discount rate assumption annually for each of its retirement-related benefit plans as of the measurement date, based on a review of projected cash flow and a long-term high-quality corporate bond yield curve. The discount rate determined on each measurement date is used to calculate the benefit obligation as of that date, and is also used to calculate the net periodic benefit (income)/cost for the upcoming plan year.

        The pension expected return on assets assumption is derived from the long-term expected returns based on the investment allocation by class specified in the Company's investment policy. The expected return on plan assets determined on each measurement date is used to calculate the net periodic benefit (income)/cost of the upcoming plan year.

        Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. To determine the health care cost trend rates the Company considers national health trends and adjusts for its specific plan design and locations.

        A one-percentage point increase in the initial through ultimate assumed health care trend rates would have increased the accumulated post-retirement benefit obligation by $8.0 at December 31, 2011 and the aggregate service and interest cost components of non-pension post-retirement benefit expense for 2011 by $0.6. A one-percentage point decrease would have decreased the obligation by $7.2 and the aggregate service and interest cost components of non-pension post-retirement benefit expense for 2011 by $0.6.

U.S. Plans

        The Company's investment objective is to achieve long-term growth of capital, with exposure to risk set at an appropriate level. This objective shall be accomplished through the utilization of a diversified asset mix consisting of equities (domestic and international) and taxable fixed income securities. The allowable asset allocation range is:

        Investment guidelines include that no security, except issues of the U.S. Government, shall comprise more than 5% of total Plan assets and further, no individual portfolio shall hold more than 7% of its assets in the securities of any single entity, except issues of the U.S. Government. The following derivative transactions are prohibited — leverage, unrelated speculation and "exotic" collateralized mortgage obligations or CMOs. Investments in hedge funds, private placements, oil and gas and venture capital must be specifically approved by the Company in advance of their purchase.

        The Company's plans have asset allocations for the U.S., as of December 31, 2011 and December 31, 2010, as follows:

U.K. Plans

        The Trustee's investment objective is to ensure that they can meet their obligation to the beneficiaries of the Plan. An additional objective is to achieve a return on the total Plan, which is compatible with the level of risk considered appropriate. The overall benchmark allocation of the Plan's assets is:

        The Company's plans have asset allocations for the U.K., as of December 31, 2011 and December 31, 2010, as follows:

Projected contributions and benefit payments

        Required pension contributions under Employee Retirement Income Security Act (ERISA) regulations are expected to be zero in 2012 and discretionary contributions are not expected in 2012. SERP and post-retirement medical plan contributions in 2012 are not expected to exceed $0.7. Expected contributions to the U.K. plan for 2012 are $8.6.

        We monitor our defined benefit pension plan asset investments on a quarterly basis and we believe that we are not exposed to any significant credit risk in these investments.

        The total benefits expected to be paid over the next ten years from the plans' assets or the assets of the Company, by country, are as follows:

 

Fair Value Measurements

        The pension plan assets are valued at fair value. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The following is a description of the valuation methodologies used for the investments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy.

        Temporary Cash Investments — These investments consist of U.S. dollars and foreign currencies held in master trust accounts. Foreign currencies held are reported in terms of U.S. dollars based on currency exchange rates readily available in active markets. These temporary cash investments are classified as level 1 investments.

        Collective Investment Trusts — These investments are public investment vehicles valued using middle market prices and performance of the fund. The trust allocates notional units to the policy holder based on the underlying notional unit buy (offer) price using the middle market price plus transaction costs. These investments are classified within level 2 of the valuation hierarchy. In addition, the collective investment trust includes a real estate fund which is classified within level 3 of the valuation hierarchy.

        Commingled Equity and Bond Funds — These investments are valued at the closing price reported by the Plan Trustee. These investments are not being traded in an active market, but are backed by various

investment securities managed by the Bank of New York. Fair value is being calculated using unobservable inputs that rely on the Bank of New York's own assumptions and are therefore classified within level 2 of the valuation hierarchy, although these assumptions are based on underlying investments which are traded on an active market.

        The Company has revised the classification of certain of its pension assets held in collective investment trusts and commingled equity and bond funds as presented in 2010. After further evaluation of the composition of these holdings, they have been reclassified from level 3 to level 2 investments.

        As of December 31, 2011 and December 31, 2010, the pension plan assets measured at fair value on a recurring basis were as follows:

 

        The table below sets forth a summary of changes in the fair value of the Plan's level 3 investment assets and liabilities for the years ended December 31, 2011 and December 31, 2010:

14.   Capital Stock

        Holdings has authorized 360,000,000 shares of stock. Of that, 200,000,000 shares are class A common stock, par value $0.01 per share, one vote per share, 150,000,000 shares are class B common stock, par value $0.01 per share, ten votes per share, and 10,000,000 shares are preferred stock, par value $0.01 per share.

        In association with the Boeing Acquisition, Spirit executives with balances in Boeing's Supplemental Executive Retirement Plan (SERP) were authorized to purchase a fixed number of units of Holdings "phantom stock" at $3.33 per unit based on the present value of their SERP balances. Under this arrangement, 860,244 phantom units were purchased. Any payment on account of units may be made in cash and/or shares of class B common stock at the sole discretion of Holdings.

15.   Stock Compensation

        Holdings has established various stock compensation plans which include restricted share grants and stock purchase plans. Compensation values are based on the value of Holdings' common stock at the grant date. The common stock value is added to equity and charged to period expense or included in inventory and cost of sales.

        For the fiscal period ended December 31, 2011, Holdings has recognized a net total of $11.2 of stock compensation expense, which is net of $1.2 resulting from stock forfeitures. Of the total $11.2 of net stock compensation expense recorded in 2011, less than $0.1 was charged directly to cost of sales, $11.1 was recorded as selling, general and administrative expense, while the remaining $0.1 was capitalized in inventory and is recognized through cost of sales consistent with the accounting methods we follow in accordance with FASB authoritative guidance. Holdings recognized a total of $28.8 and $10.1 of stock compensation expense for the periods ended December 31, 2010 and December 31, 2009, respectively. The total income tax benefit recognized in the income statement for share based compensation arrangements was $4.1, $10.8, and $3.8 for 2011, 2010, and 2009, respectively.

Executive Incentive Plan

        The Company's Executive Incentive Plan, or EIP, is designed to provide participants with the opportunity to acquire an equity interest in the Company through direct purchase of the Company's class B common stock shares at prices established by the Board of Directors or through grants of class B restricted common stock shares with performance based vesting. The Company has the sole authority to designate either stock purchases or grants of restricted shares. The total number of shares authorized under the EIP is 12,000,000 and the grant terminates at the end of ten years.

        The Company has issued restricted shares as part of the Company's EIP. The restricted shares have been granted in groups of four shares. Participants do not have the unrestricted rights of stockholders until those shares vest. The shares may vest upon a liquidity event, with the number of shares vested based upon a participant's number of years of service to the Company, the portion of the investment by Onex and its affiliates liquidated through the date of the liquidity event and the return on invested capital by Onex and its affiliates through the date of the liquidity event. If a specific type of liquidity event has not occurred by the 10th year, shares may vest based on a valuation of the Company. The Company's initial public offering in November 2006 (the "IPO") and secondary offerings in May 2007 and April 2011 were considered liquidity events under the EIP. The Company records expenses equal to the fair value of the award over a five-year vesting period. The fair value of the award is based on the value of each share at the time of the grant multiplied by the probability of the share vesting based on historical performance of Onex's controlled investments.

        The Company expensed less than $0.1 for shares granted under the EIP, which was offset by $0.5 expense reduction resulting from stock forfeitures for the year ended December 31, 2011. The Company expensed a net total of $1.8 and $2.3 for the periods ended December 31, 2010 and December 31, 2009, respectively. The weighted average remaining period for the vesting of these shares is 3.5 years. The intrinsic value of the unvested shares based on the value of the Company's stock at December 31, 2011 was $33.9, based on the value of the Company's stock and the number of unvested shares.

        Due to the occurrence during 2011 of the five-year anniversaries of the Executive Incentive Plan grant dates for certain participants in the plan, those participants acquired an incremental 20% interest in the shares granted to them under the plan, such that their total cumulative interest in the shares granted to them would be 100%. The total number of additional shares in which an interest was acquired during 2011 was 115,277. The participants have a non-forfeitable interest in those shares; however, as per the plan document, the shares are still restricted until the earlier of a liquidity event or June 16, 2015. Participants do not have the unrestricted rights of stockholders until those shares vest.

        The following table summarizes the activity of restricted shares under the EIP for the periods ended December 31, 2011, December 31, 2010 and December 31, 2009:

Board of Directors Stock Awards

        This plan provides non-employee directors the opportunity to receive grants of restricted shares of class A common stock, or Restricted Stock Units (RSUs) or a combination of both common stock and RSUs. The class A common stock grants and RSU grants vest one year from the grant date. The RSU grants are payable upon the director's separation from service. The Board of Directors or its authorized committee may make discretionary grants of shares or RSUs from time to time. The maximum aggregate number of shares that may be granted to participants is 3,000,000 shares. In April 2008, the Director Stock Plan was amended such that all issuance of stock pursuant to the plan after that date would be grants of class A common stock or RSUs. All shares granted prior to April 2008 were class B common stock.

        For each non-employee director of the Company, at least one-half of their annual director compensation is required to be paid in the form of a grant of class A common stock and/or RSUs, as elected by each director. In addition, each director may elect to have all or any portion of the remainder of their annual director compensation paid in cash or in the form of a grant of class A stock and/or RSUs. If participants cease to serve as directors within a year of the grant, the restricted shares and/or RSUs are forfeited. In May 2011, the Board of Directors authorized a grant to its members of 30,247 shares of restricted class A common stock valued at $0.7 based on the share price of the Company's common stock at the grant date. Of these 3,184 shares valued at $0.1 were forfeited due to retirement of a director during the year. The Company expensed a net amount of $0.7 for the Board of Directors shares for the period ended December 31, 2011. The Company expensed $0.7 during each of the periods ended December 31, 2010 and December 31, 2009. The Company's unamortized stock compensation related to these restricted shares is $0.2 which will be recognized over a weighted average remaining period of 4 months. The intrinsic value of the unvested shares based on the value of the Company's stock at December 31, 2011 was $0.6, based on the value of the Company's stock and the number of unvested shares.

        The following table summarizes stock and RSU grants to members of the Company's Board of Directors for the periods ended December 31, 2009, December 31, 2010 and December 31, 2011:

Short-Term Incentive Plan

        The Second Amended and Restated Short-Term Incentive Plan ("STIP") enables eligible employees to receive incentive benefits in the form of restricted stock in the Company, cash, or both, as determined by the Board of Directors or its authorized committee. The stock portion vests one year from the date of grant. Restricted shares are forfeited if the employee's employment terminates prior to vesting. In August 2011, the STIP was amended such that all unvested stock will vest in the event of a qualifying retirement or change in control.

        In February 2011, 185,153 shares of Class A common stock with a value of $4.7 were granted under the Company's STIP for 2010 performance and will vest on the one-year anniversary of the grant date. During 2011, the Company expensed $3.9 for shares granted under the STIP. The Company expensed $0.4 and $3.3 for the shares for the periods ended December 31, 2010, and December 31, 2009 respectively. The Company's unamortized stock compensation related to the unvested shares is $0.7, which will be recognized over a weighted average remaining period of 2 months. The intrinsic value of the unvested shares at December 31, 2011 was $3.6 based on the value of the Company's stock and the number of unvested shares.

        The following table summarizes the activity of the restricted shares under the STIP for the twelve months ended December 31, 2009, December 31, 2010 and December 31, 2011:

Long-Term Incentive Plan

        The Fourth Amended and Restated Long-Term Incentive Plan ("LTIP") is designed to encourage retention of key employees.

        For shares granted in 2007, one-half of the granted restricted shares of class B common stock vested on the second anniversary of the grant date in February 2009, and the other one-half vested on the fourth anniversary of the grant date in 2011. Restricted shares are forfeited if the participant's employment terminates prior to vesting. In the first quarter of 2007, 67,391 shares valued at $2.0 were granted. The Company expensed less than $0.1 net of forfeitures for the period ended December 31, 2011, and $0.4 for each of the periods ended December 31, 2010, December 31, 2009 and December 31, 2008.

        In May 2011, 548,334 class A shares valued at $12.9 were granted and will vest annually in three equal installments beginning on the two-year anniversary of the grant date. In May 2010, 562,708 class A shares valued at $12.1 were granted (and an additional 1,826 class A shares valued at less than $0.1 were granted during February 2011 for 2010 compensation). These shares begin to vest annually in three equal installments beginning on the two-year anniversary of the May 2010 grant date. During May 2009, 852,294 class A shares valued at $11.0 were granted in May 2009. These shares vest annually in three equal installments beginning on the two-year anniversary of the grant date. Within the May 2008 LTIP grant were three groups of awards, each with a unique vesting schedule. The first group of shares vested equally over three years, beginning in 2009. The second and third groups also vest in one-third increments, but vesting began on the second and third anniversary of the grant, respectively.

        During 2011, 500 shares of class A common stock with a value of less than $0.1 were granted to members of the UAW union under the LTIP pursuant to the new ten-year labor contract. These shares vested immediately and the value was charged directly to cost of sales.

        The Company expensed a total of $7.0 for the unvested class A LTIP shares in the twelve months ended December 31, 2011, net of $0.7 of forfeited shares. The Company expensed a net total of $25.5 and $3.5 for class A LTIP shares for the periods ended December 31, 2010 and December 31, 2009, respectively.

        The Company's unamortized stock compensation related to these unvested class A shares is $19.0 which will be recognized over a weighted average remaining period of 2.6 years. The intrinsic value of the unvested class A LTIP shares at December 31, 2011 was $32.4, based on the value of the Company's common stock and the number of unvested shares.

Dividends on Restricted Share Grants

        Spirit does not currently have plans to pay dividends in the foreseeable future. However, any dividends declared by Holdings' Board of Directors with respect to common shares and with respect to any restricted share grants under any of the Company's compensation plans will be cumulative and paid to the participants only at the time and to the extent the participant acquires an interest in, or vests, in any of the restricted shares.

16.   Income Taxes

        The following summarizes pretax income:

        The tax provision contains the following components:

        The income tax provision from operations differs from the tax provision computed at the U.S. federal statutory income tax rate due to the following:

        Significant tax effected temporary differences comprising the net deferred tax asset are as follows:

        Deferred tax detail above is included in the consolidated balance sheet and supplemental information as follows:

        The increase in the depreciation and amortization deferred tax liability is primarily due to enacted bonus depreciation rules.

        We have recognized cumulative book income for our international operations, but have incurred cumulative taxable losses in the United Kingdom. The resulting net operating loss carryforward is primarily due to the manner in which the United Kingdom treats long-term contract income accounting and capital allowances.

        As required under FASB authoritative guidance, $1.1 and $5.0 was recorded to Additional Paid in Capital, representing the tax effect associated with the net excess tax pool created during 2011 and 2010, respectively.

        In accordance with FASB authoritative guidance relating to Accounting for Income Taxes, management has maintained a permanent reinvestment strategy for the Company's foreign operations. As such, deferred taxes have not been provided on unremitted earnings for our U.K., Germany, Malaysia,

Singapore, Canada, and France subsidiaries. These unremitted earnings would have an immaterial impact, if any, on the financial statements, if repatriated.

        The beginning and ending unrecognized tax benefits reconciliation is as follows:

        Included in the December 31, 2011 balance were $13.5 in tax affected unrecognized tax benefits which, if ultimately recognized, will reduce the Company's effective tax rate. The Internal Revenue Service is currently examining the Company's 2008 and 2009 U.S. Federal income tax returns and we are participating in the Compliance Assurance Process ("CAP") program for our 2011 tax year. The CAP program's objective is to resolve issues in a timely, contemporaneous manner and eliminate the need for a lengthy post-filing examination. HM Revenue & Customs is currently examining our 2008 U.K. income tax return. While a change could result from the ongoing examinations, the Company expects no material change in its recorded unrecognized tax benefit liability in the next 12 months.

        Our U.S. federal income tax returns for the 2008-2011 tax years are subject to examination. We are also subject to examination in states and foreign jurisdictions for the 2008-2011 tax years.

        We report interest and penalties, if any, related to unrecognized tax benefits in the income tax provision. As of December 31, 2011 and December 31, 2010, accrued interest on our unrecognized tax benefit liability included in the consolidated balance sheets was $0.1 and $0.7, respectively. The impact of interest on our unrecognized tax benefit liability during 2011 and 2010 was $(0.6) and $(1.2), respectively.

        We continue to operate under a tax holiday in Malaysia effective through September 2024. During the current year, management established a reserve for potential uncertainty in meeting the tax holiday's conditional employment and investment thresholds.

        At December 31, 2011, we had $45.7 in United Kingdom net operating loss carryforwards that do not expire and $34.4 in North Carolina net operating loss carryforwards that expire in 2025.

        Included in the deferred tax assets at December 31, 2011 are $27.1 in Kansas High Performance Incentive Program ("HPIP") Credit, $12.8 in Kansas Research & Development ("R&D") Credit, and $4.5 in Kansas Business and Jobs Development Credit totaling $44.4 in Kansas state income tax credit carryforwards. The HPIP Credit provides a 10% investment tax credit for qualified business facilities located in Kansas for which $4.3 expires in 2016, $13.1 expires in 2017, $1.7 expires in 2018, $7.0 expires in 2019, and the remainder expires in 2020. The R&D Credit provides a credit for qualified research and development expenditures conducted within Kansas. This credit can be carried forward indefinitely. The Business and Jobs Development Credit provides a tax credit for increased employment in Kansas. This credit can be carried forward indefinitely. It is management's opinion that all Kansas state income tax credits carried forward will be utilized before they expire.

        Included in the deferred tax assets at December 31, 2011 are $14.3 in North Carolina Investing in Business Property Credit, $5.9 in North Carolina Investment in Real Property Credit, and $2.9 in North

129

Carolina Creating Jobs Credit totaling $23.1 in North Carolina state income tax credit carryforwards. The Investing in Business Property Credit provides a 7% investment tax credit for property located in a North Carolina development area and the Investment in Real Property Credit provides a 30% investment tax credit for real property located in a North Carolina development area. The Creating Jobs Credit provides a tax credit for increased employment in North Carolina. These North Carolina state income tax credits can be carried forward 20 years. It is management's opinion that $10.5 of these North Carolina state income tax credits will be utilized before they expire and a $12.6 gross valuation allowance was recorded.

17.   Equity

Earnings per Share Calculation

        Basic earnings per share represents the income available to common shareholders divided by the weighted average number of common shares outstanding during the measurement period. Diluted earnings per share represents the income available to common shareholders divided by the weighted average number of common shares outstanding during the measurement period while also giving effect to all potentially dilutive common shares that were outstanding during the period.

        Subject to preferences that may apply to shares of preferred stock outstanding at the time, holders of the Company's outstanding common stock are entitled to any dividend declared by the Board of Directors out of funds legally available for this purpose. No dividend may be declared on the class A or class B common stock unless at the same time an equal dividend is paid on every share of class A and class B common stock. Dividends paid in shares of the Company's common stock must be paid, with respect to a particular class of common stock, in shares of that class. The Company does not intend to pay cash dividends on its common stock. In addition, the terms of the Company's current financing agreements preclude it from paying any cash dividends on its common stock.

        The following table sets forth the computation of basic and diluted earnings per share:

        The balance of outstanding common shares presented in the consolidated statement of shareholders' equity was 142.9 million, 142.1 million and 140.7 million at December 31, 2011, December 31, 2010 and December 31, 2009, respectively. Included in the outstanding common shares were 2.6 million, 2.9 million and 3.5 million of issued but unvested shares at December 31, 2011, December 31, 2010 and December 31, 2009 respectively, which are excluded from the basic EPS calculation.

        On March 26, 2007, Hawker Beechcraft, Inc. ("Hawker"), of which Onex Partners II LP (an affiliate of Onex) owns approximately a 49% interest, acquired Raytheon Aircraft Acquisition Company and substantially all of the assets of Raytheon Aircraft Services Limited. The Company's Prestwick facility provides wing components for the Hawker 800 Series manufactured by Hawker. For the twelve months ended December 31, 2011, December 31, 2010 and December 31, 2009 sales to Hawker were $10.2, $6.7 and $12.0, respectively. Receivables due from Hawker were $3.9 as of December 31, 2011, net of a $0.3 receivable write-off.

        A former member of Holdings' Board of Directors, who resigned from such position effective October 26, 2010, was also a member of the Board of Directors of Hawker.

        Prior to his departure from the Company in December 2009, a former executive of the Company was a member of the Board of Directors of one of the Company's suppliers, Precision Castparts Corp. of Portland, Oregon, a manufacturer of complex metal components and products. For the twelve months ended December 31, 2009 the Company purchased $48.3 of products from this supplier.

        A member of Holdings' Board of Directors served as Chairman, President, and Chief Executive Officer of Aviall, Inc., the parent company of one of our customers, Aviall Services, Inc. and a wholly-owned subsidiary of Boeing until his retirement in February 2010. On September 18, 2006, Spirit entered into a distribution agreement with Aviall Services, Inc., which has terminated. Net revenues under the distribution agreement were $4.0 and $2.8 for the twelve months ended December 31, 2010 and December 31, 2009, respectively.

        The Company paid $0.2, $0.3, and $0.2 to a subsidiary of Onex for services rendered for each of the twelve month periods ended December 31, 2011, December 31, 2010, and December 31, 2009, respectively. Management believes the amounts charged were reasonable in relation to the services provided.

        Boeing owned and operated significant information technology systems utilized by the Company and, as required under the acquisition agreement for the Boeing Acquisition, was providing those systems and support services to Spirit under a Transition Services Agreement.

Services Agreement have now been established by the Company, and the agreement terminated. Under the Transition Services Agreement, the Company incurred fees of zero, less than $0.1 and $13.7 for the twelve months ended December 31, 2011, December 31, 2010 and December 31, 2009, respectively. The amounts owed to Boeing and recorded as accrued liabilities were zero and less than $0.1 at December 31, 2011 and December 31, 2010, respectively.

        The spouse of one of the Company's recently retired executives is a special counsel at a law firm utilized by the Company and at which the executive was previously employed. The Company paid fees of $1.9, $1.3, and $1.9 to the firm for the periods ended December 31, 2011, December 31, 2010, and December 31, 2009, respectively.

        On April 20, 2011, an executive of the Company was elected to the Board of Directors of Rockwell Collins, Inc., a supplier of manufacturing parts to the Company. Under the commercial terms of the arrangement with the supplier, Spirit paid less than $0.1 for the twelve months ended December 31, 2011. The amounts owed to Rockwell Collins and recorded as accrued liabilities were less than $0.1 as of December 31, 2011.

        An executive of the Company is a member of the Board of Directors of a Wichita, Kansas bank that provides banking services to Spirit. In connection with the banking services provided to Spirit, the Company pays fees consistent with commercial terms that would be available to unrelated third parties. Such fees are not material to the Company.

19.   Commitments, Contingencies and Guarantees

Litigation

        From time to time we are subject to, and are presently involved in, litigation or other legal proceedings arising in the ordinary course of business. While the final outcome of these matters cannot be predicted with certainty, considering, among other things, the meritorious legal defenses available, it is the opinion of the Company that none of these items, when finally resolved, will have a material adverse effect on the Company's long-term financial position or liquidity. Consistent with the requirements of authoritative guidance on accounting for contingencies, we had no accruals at December 31, 2011 or December 31, 2010 for loss contingencies. However, an unexpected adverse resolution of one or more of these items could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

        From time to time, in the ordinary course of business and like others in the industry, we receive requests for information from government agencies in connection with their regulatory or investigational authority. Such requests can include subpoenas or demand letters for documents to assist the government in audits or investigations. We review such requests and notices and take appropriate action. We have been subject to certain requests for information and investigations in the past and could be subject to such requests for information and investigations in the future. Additionally, we are subject to federal and state requirements for protection of the environment, including those for disposal of hazardous waste and remediation of contaminated sites. As a result, we are required to participate in certain government investigations regarding environmental remediation actions.

        In December 2005, a lawsuit was filed against Spirit, Onex, and Boeing alleging age discrimination in the hiring of employees by Spirit when Boeing sold its Wichita commercial division to Onex. The complaint was filed in U.S. District Court in Wichita, Kansas and seeks class-action status, an unspecified amount of compensatory damages and more than $1.5 billion in punitive damages. The asset purchase agreement from the Boeing Acquisition requires Spirit to indemnify Boeing for damages resulting from the

employment decisions that were made by us with respect to former employees of Boeing Wichita, which relate or allegedly relate to the involvement of, or consultation with, employees of Boeing in such employment decisions. On June 30, 2010, the U.S. District Court granted defendants' dispositive motions, finding that the case should not be allowed to proceed as a class action. The matter is now on appeal to the Tenth Circuit Court of Appeals, which could reverse the District Court's June 30, 2010 ruling. The Company intends to continue to vigorously defend itself in this matter. Management believes the resolution of this matter will not materially affect the Company's financial position, results of operations or liquidity.

        In December 2005, a federal grand jury sitting in Topeka, Kansas issued subpoenas regarding the vapor degreasing equipment at our Wichita, Kansas facility. The government's investigation appeared to focus on whether the degreasers were operating within permit parameters and whether chemical wastes from the degreasers were disposed of properly. The subpoenas covered a time period both before and after our purchase of the Wichita, Kansas facility. Subpoenas were issued to Boeing, Spirit and individuals who were employed by Boeing prior to the Boeing Acquisition, but are now employed by us. We responded to the subpoena and provided additional information to the government as requested. On March 25, 2008, the U.S. Attorney's Office informed the Company that it was closing its criminal file on the investigation. A civil investigation into this matter is ongoing. Management believes the resolution of this matter will not materially affect the Company's financial position, results of operations or liquidity.

        On February 16, 2007, an action entitled Harkness et al. v. The Boeing Company et al. was filed in the U.S. District Court for the District of Kansas. The defendants were served in early July 2007. The defendants include Spirit AeroSystems Holdings, Inc., Spirit AeroSystems, Inc., the Spirit AeroSystems Holdings Inc. Retirement Plan for the International Brotherhood of Electrical Workers (IBEW), Wichita Engineering Unit (SPEEA WEU) and Wichita Technical and Professional Unit (SPEEA WTPU) Employees, and the Spirit AeroSystems Retirement Plan for International Association of Machinists and Aerospace Workers (IAM) Employees, along with Boeing and Boeing retirement and health plan entities. The named plaintiffs are twelve former Boeing employees, eight of whom were or are employees of Spirit. The plaintiffs assert several claims under the Employee Retirement Income Security Act and general contract law and brought the case as a class action on behalf of similarly situated individuals. The putative class consists of approximately 2,500 current or former employees of Spirit. The parties agreed to class certification and are currently in the discovery process. The sub-class members who have asserted claims against the Spirit entities are those individuals who, as of June 2005, were employed by Boeing in Wichita, Kansas, were participants in the Boeing pension plan, had at least 10 years of vesting service in the Boeing plan, were in jobs represented by a union, were between the ages of 49 and 55, and who went to work for Spirit on or about June 17, 2005. Although there are many claims in the suit, the plaintiffs' claims against the Spirit entities, asserted under various theories, are (1) that the Spirit plans wrongfully failed to determine that certain plaintiffs are entitled to early retirement "bridging rights" to pension and retiree medical benefits that were allegedly triggered by their separation from employment by Boeing and (2) that the plaintiffs' pension benefits were unlawfully transferred from Boeing to Spirit in that their claimed early retirement "bridging rights" are not being afforded these individuals as a result of their separation from Boeing, thereby decreasing their benefits. The plaintiffs seek a declaration that they are entitled to the early retirement pension benefits and retiree medical benefits, an injunction ordering that the defendants provide the benefits, damages pursuant to breach of contract claims and attorney fees. Boeing has notified Spirit that it believes it is entitled to indemnification from Spirit for any "indemnifiable damages" it may incur in the Harkness litigation, under the terms of the asset purchase agreement from the Boeing Acquisition between Boeing and Spirit. Spirit disputes Boeing's position on indemnity. Management believes the resolution of this matter will not materially affect the Company's financial position, results of operations or liquidity.

        On July 21, 2005, the International Union, Automobile, Aerospace and Agricultural Implement Workers of America ("UAW") filed a grievance against Boeing on behalf of certain former Boeing employees in Tulsa and McAlester, Oklahoma, regarding issues that parallel those asserted in Harkness et al. v. The Boeing Company et al. Boeing denied the grievance, and the UAW subsequently filed suit to compel arbitration, which the parties eventually agreed to pursue. The arbitration was conducted in January 2008. In July 2008, the arbitrator issued an opinion and award in favor of the UAW. The arbitrator directed Boeing to reinstate the seniority of the employees and "afford them the benefits appurtenant thereto." On March 5, 2009, the arbitrator entered an Opinion and Supplemental Award that directed Boeing to award certain benefits to UAW members upon whose behalf the grievance was brought, notwithstanding the prior denial of such benefits by the Boeing Plan Administrator. On April 10, 2009, Boeing filed a Complaint in the United States District Court for the Northern District of Illinois, seeking a ruling that the Arbitrator exceeded his authority in granting the Supplemental Award. On September 16, 2009, the District Court entered an order affirming the arbitrator's Supplemental Award. Boeing appealed the District Court's decision to the U.S. Seventh Circuit Court of Appeals, which affirmed the District Court's decision. Boeing previously notified Spirit of its intent to seek indemnification from Spirit for any "indemnifiable damages" it may incur in the UAW matter, pursuant to the terms of the asset purchase agreement from the Boeing Acquisition. Spirit disputes Boeing's position on indemnity. Management believes the resolution of this matter will not materially affect the Company's financial position, results of operations or liquidity.

        On May 11, 2009, Spirit filed a lawsuit in the United States District Court for the District of Kansas against SPS Technologies LLC ("SPS"), and Precision Castparts Corp. Spirit's claims are based on the sale by SPS of certain non-conforming nutplate fasteners to Spirit between August 2007 and August 2008. Many of the fasteners were used on assemblies that Spirit sold to a customer. In the fall of 2008, Spirit discovered the non-conformity and notified the customer of the discrepancy. Subsequently, Spirit and the customer removed and replaced nutplates on various in-process aircraft assemblies and subsequently agreed to an appropriate cost, to be borne by Spirit, related to those efforts. Spirit's lawsuit seeks damages, including damages related to these efforts, under various theories, including breach of contract and breach of implied warranty.

Commitments

        The Company leases equipment and facilities under various non-cancelable capital and operating leases. The capital leasing arrangements extend through 2025. Minimum future lease payments under these leases at December 31, 2011 are as follows:

($, €, £, and RM in millions other than per share amounts)

        Operating lease payments were as follows:

        Spirit's aggregate capital commitments totaled $264.2 and $219.6 at December 31, 2011 and December 31, 2010, respectively.

        The Company paid $0.6 and $0.2 in interest expense related to the capital leases for periods ending December 31, 2011 and December 31, 2010, respectively.

Guarantees

        Contingent liabilities in the form of letters of credit, letters of guarantee and performance bonds have been provided by the Company. These letters of credit reduce the amount of borrowings available under the revolving credit facility. As of December 31, 2011 and December 31, 2010, outstanding letters of credit were $19.9 and $18.9, respectively, and outstanding guarantees were $26.6 and $23.1, respectively.

Indemnification

        The Company has entered into customary indemnification agreements with each of its Directors, and some of its executive employment agreements include indemnification provisions. Under those agreements, the Company agrees to indemnify each of these individuals against claims arising out of events or occurrences related to that individual's service as the Company's agent or the agent of any of its subsidiaries to the fullest extent legally permitted.

Service and Product Warranties and Extraordinary Rework

        The Company provides service and warranty policies on its products. Liability under service and warranty policies is based upon specific claims and a review of historical warranty and service claim experience. Adjustments are made to accruals as claim data and historical experience change. In addition, the Company incurs discretionary costs to service its products in connection with product performance or quality issues.

        The following is a roll forward of the service warranty and extraordinary rework balance at December 31, 2011:

Bonds

        Spirit utilized City of Wichita issued Industrial Revenue Bonds ("IRBs") to finance self-constructed and purchased real and personal property at the Wichita site. Tax benefits associated with IRBs include provisions for a ten-year complete property tax abatement and a Kansas Department of Revenue sales tax exemption on all IRB funded purchases. Spirit and the Predecessor purchased these IRBs so they are bondholders and debtor / lessee for the property purchased with the IRB proceeds.

        Spirit recorded the property on its consolidated balance sheet in accordance with FASB authoritative guidance, along with a capital lease obligation to repay the IRB proceeds. Therefore, Spirit and the Predecessor have exercised their right to offset the amounts invested and obligations for these bonds on a consolidated basis. At December 31, 2011 and 2010, the assets and liabilities associated with these IRBs were $286.2 and $271.2, respectively.

        Spirit utilized $80.0 in KDFA issued bonds to receive a rebate of payroll taxes from the Kansas Department of Revenue to KDFA bondholders. Concurrently, a Spirit subsidiary issued an intercompany note with identical principal, terms, and conditions to the KDFA bonds. In accordance with FASB authoritative guidance, the principal and interest payments on these bonds offset in the consolidated financial statements.

Long-term Contracts

        The Fuselage, Propulsion and Wing segments have several long-term contracts in the pre-production and production phases including the sustaining Boeing programs, the sustaining Airbus programs and the new B787 and A350 XWB programs. These contracts are accounted for in accordance with long-term construction contract accounting. These contracts include excess-over-average inventories, which represent the excess of current manufactured cost over the estimated average manufactured cost during the life of the contract.

        Cost estimates over the lives of contracts are affected by estimates of future cost reductions including learning curve efficiencies. Because these contracts cover manufacturing periods of up to 20 years or more, there is risk associated with the estimates of future costs made during the pre-production and early production phases. These estimates may be different from actual costs due to various factors, including the following:

•

Ability to recover costs incurred for change orders and claims;



•

Costs, including material and labor costs and related escalation;



•

Labor improvements due to the learning curve experience;



•

Anticipated cost productivity improvements, including overhead absorption, related to new, or changes to, manufacturing methods and processes;



•

Supplier pricing, including escalation where applicable, potential supplier claims, the supplier's financial viability and the supplier's ability to perform;



•

The cost impact of product design changes that frequently occur during the flight test and certification phases of a program, including contractual claims by suppliers against the Company for cost recovery on product design changes that flow through the supply chain; and



•

Effect of foreign currency exchange fluctuations.

Additionally, total contract revenue is based on estimates of future units to be delivered to the customer, the ability to recover costs incurred for change orders and claims and sales price escalation, where applicable. There is a risk that there could be differences between the actual units delivered and the estimated total units to be delivered under the contract and differences in actual revenues compared to estimates. Changes in estimates could have a material impact on the Company's results of operations and cash flows.

        Provisions for estimated losses on uncompleted contracts are recorded in the period such losses are determined to the extent total estimated costs exceed total estimated contract revenues.

20.   Other Income (Expense), Net

        Other income (expense), net, is summarized as follows:

        Foreign currency gains (losses) are due to the impact of movement in foreign currency exchange rates on trade and intercompany receivables/payables and other long-term contractual rights/obligations denominated in a currency other than the entity's functional currency.

21.   Significant Concentrations of Risk

Economic Dependence

        The Company's largest customer (Boeing) accounted for approximately 85%, 83%, and 85% of the revenues for the periods ending December 31, 2011, December 31, 2010, and December 31, 2009, respectively. Approximately 33% and 35% of the Company's accounts receivable balance at December 31, 2011 and December 31, 2010, respectively, was attributable to Boeing.

22.   Supplemental Balance Sheet Information

        Accrued expenses and other liabilities consist of the following:

---

(1)

As part of the B787 Amendment, Spirit agreed to pay Boeing for work to complete initial production units.

23.   Segment Information

        The Company operates in three principal segments: Fuselage Systems, Propulsion Systems and Wing Systems. Substantially all revenues in the three principal segments are from Boeing, with the exception of Wing Systems, which includes revenues from Airbus and other customers. Approximately 95% of the Company's net revenues for the twelve months ended December 31, 2011 came from our two largest customers, Boeing and Airbus. All other activities fall within the All Other segment, principally made up of sundry sales of miscellaneous services, tooling contracts, and sales of natural gas through a tenancy-in-common with other companies that have operations in Wichita, Kansas. The Company's primary profitability measure to review a segment's operating performance is segment operating income before unallocated corporate selling, general and administrative expenses, unallocated research and development and unallocated cost of sales. Unallocated corporate selling, general and administrative expenses include centralized functions such as accounting, treasury and human resources that are not specifically related to our operating segments and are not allocated in measuring the operating segments' profitability and performance and operating margins. Unallocated research and development includes research and development efforts that benefit the Company as a whole and are not unique to a specific segment. Unallocated cost of sales is related to an increase in warranty and extraordinary rework reserves and early retirement elected by eligible UAW represented employees during the second quarter of 2011, and in 2010 related to the grant of shares to employees represented by the IAM in connection with the ratification of a new ten-year labor contract on June 25, 2010. All of these unallocated items are not

specifically related to our operating segments and are not allocated in measuring the operating segments' profitability and performance and operating margins.

        The Company's Fuselage Systems segment includes development, production and marketing of forward, mid and rear fuselage sections and systems, primarily to aircraft OEMs (OEM refers to aircraft original equipment manufacturer), as well as related spares and maintenance, repairs and overhaul (MRO). The Fuselage Systems segment manufactures products at our facilities in Wichita, Kansas and Kinston, North Carolina. The Fuselage Systems segment also includes an assembly plant for the A350 XWB aircraft in Saint-Nazaire, France.

        The Company's Propulsion Systems segment includes development, production and marketing of struts/pylons, nacelles (including thrust reversers) and related engine structural components primarily to aircraft or engine OEMs, as well as related spares and MRO services. The Propulsion Systems segment manufactures products at our facilities in Wichita, Kansas.

        The Company's Wing Systems segment includes development, production and marketing of wings and wing components (including flight control surfaces) as well as other miscellaneous structural parts primarily to aircraft OEMs, as well as related spares and MRO services. These activities take place at the Company's facilities in Tulsa and McAlester, Oklahoma, Kinston, North Carolina, Prestwick, Scotland and Subang, Malaysia.

        The Company's segments are consistent with the organization and responsibilities of management reporting to the chief operating decision-maker for the purpose of assessing performance. The Company's definition of segment operating income differs from operating income as presented in its primary financial statements and a reconciliation of the segment and consolidated results is provided in the table set forth below. Most selling, general and administrative expenses, and all interest expense or income, related financing costs and income tax amounts, are not allocated to the operating segments.

        While some working capital accounts are maintained on a segment basis, much of the Company's assets are not managed or maintained on a segment basis. Property, plant and equipment, including tooling, is used in the design and production of products for each of the segments and, therefore, is not allocated to any individual segment. In addition, cash, prepaid expenses, other assets and deferred taxes are managed and maintained on a consolidated basis and generally do not pertain to any particular segment. Raw materials and certain component parts are used in the production of aerostructures across all segments. Work-in-process inventory is identifiable by segment, but is managed and evaluated at the program level. As there is no segmentation of the Company's productive assets, depreciation expense (included in fixed manufacturing costs and selling, general and administrative expenses) and capital expenditures, no allocation of these amounts has been made solely for purposes of segment disclosure requirements.

Item 9A.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

        Our President and Chief Executive Officer and Senior Vice President and Chief Financial Officer have evaluated our disclosure controls as of December 31, 2011 and have concluded that these disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934) are effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time period specified in the SEC rules and forms. These disclosure controls and procedures include, without limitation, controls and procedures designed to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit is accumulated and communicated to management, including the President and Chief Executive Officer and the Senior Vice President and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Management's Annual Report on Internal Control over Financial Reporting

        Our management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934. Internal control over financial reporting provides reasonable assurance of the reliability of our financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. Internal control involves maintaining records that accurately represent our business transactions, providing reasonable assurance that receipts and expenditures of company assets are made in accordance with management authorization, and providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on our financial statements would be detected or prevented on a timely basis.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatement. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in condition, or that the degree of compliance with the policies or procedures may deteriorate.

        Management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation under the framework in Internal Control — Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2011. The effectiveness of the Company's internal control over financial reporting as of December 31, 2011, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm as stated in their report which appears herein.

Changes in Internal Controls over Financial Reporting

        There were no changes in our internal control over financial reporting that occurred during the fourth quarter of 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
