Amphenol Corporation (NYSE: APH) today reported fourth quarter and full year 2021 results.

“We are pleased to have closed 2021 with fourth quarter sales and Adjusted Diluted EPS significantly exceeding the high end of our guidance,” said Amphenol President and Chief Executive Officer, R. Adam Norwitt. “Sales increased from prior year by a strong 25% in the quarter, with particularly robust growth in the IT data communications, industrial, mobile networks, commercial air, automotive and broadband markets, including contributions from the Company’s acquisition program. For the full year, sales increased 26% compared to 2020, driven by strong growth across virtually all end markets, including contributions from the Company’s acquisition program. Despite facing substantial inflationary pressures and supply chain disruptions, full year Adjusted Diluted EPS grew by an impressive 33%. We are very proud of the Company’s outstanding performance in this most challenging and dynamic year.”

“Throughout the year, we continued to deploy our financial strength in a variety of ways to increase shareholder value. During the fourth quarter, the Company purchased 2.1 million shares of its common stock for $171 million and paid dividends of $87 million, resulting in total capital returned to shareholders in 2021 of more than $1 billion.”

“We remain focused on expanding our growth opportunities through a deep commitment to developing enabling technologies for customers in all markets, an ongoing strategy of market and geographic diversification and an active and successful acquisition program. To that end, we were excited to have announced on December 1, 2021, the acquisition of Halo Technology Limited, as well as the closing of the sale of the MTS Test & Simulation business to Illinois Tool Works Inc. (NYSE: ITW). With the closing of the Halo acquisition, we successfully completed seven acquisitions in 2021. These new companies have broadened our high-technology product offering, expanded our position across most of our end markets and deepened our pool of talented, entrepreneurial managers around the world.”

Creation of Three New Divisions

Effective January 1, 2022, Amphenol aligned its business units into three newly formed Divisions: Harsh Environment Solutions (HES), Communications Solutions (CS), and Interconnect and Sensor Systems (ISS). This new alignment reinforces the Company’s entrepreneurial culture and the clear accountability of each of our business unit general managers, while enhancing the scalability of Amphenol’s business for the future. Beginning with the first quarter of 2022, the Company will report the financial results of these three new Divisions as separate reportable segments, replacing the Company’s previous two reportable segments. We will provide the results of these new reportable segments, as well as comparable historical financial data, with our first quarter 2022 results.

First Quarter 2022 Outlook

The current market environment remains highly uncertain, with continued supply chain and inflationary challenges as well as potential new disruptions from the recent resurgence of Covid-19. Assuming conditions do not meaningfully worsen and assuming constant exchange rates, for the first quarter of 2022, Amphenol expects sales to be in the range of $2.690 billion to $2.750 billion, representing 13% to 16% growth over the first quarter of 2021, and Adjusted Diluted EPS in the range of $0.59 to $0.61, representing 13% to 17% growth over the first quarter of 2021.

“Despite the ongoing challenges and uncertainties, we continue to face around the world, we are very pleased with the platform of strength that has been created by the Company’s superior performance in 2021,” Mr. Norwitt continued. “The revolution in electronics is accelerating, thereby creating exciting and dynamic long-term growth opportunities for Amphenol across each of our diversified end markets. Indeed, the last two pandemic-impacted years have revealed more than ever before the importance of innovative, new electronic applications. We believe these opportunities will enable a further, long-term increase in the demand for our expanding range of high-technology interconnect, sensor and antenna products. Our ongoing drive to leverage our competitive advantages and create sustained financial strength, as well as our initiatives to expand our product offerings, both organically and through our acquisition program, have created an excellent base for the Company’s future performance. In addition, we continue to take steps to further scale our unique, entrepreneurial organization to support the Company’s long-term growth potential, including the alignment of our business units into three new Divisions. I am confident in the ability of our outstanding entrepreneurial management team to continue to dynamically adjust to changing market conditions, to capitalize on the wide array of growth opportunities that arise in all market cycles and to continue to generate sustainable long-term value for our shareholders and other stakeholders. Most importantly, I remain truly grateful to our team for their extraordinary efforts to protect the safety and health of our employees around the world throughout the ongoing pandemic, all while continuing to strongly support our customers and drive outstanding operating performance.”

The financial statements included within this press release are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP” or “U.S. GAAP”). This press release also contains certain non-GAAP financial measures, including Adjusted Operating Income, Adjusted Operating Margin, Adjusted Net Income from continuing operations attributable to Amphenol Corporation, Adjusted Effective Tax Rate, Adjusted Diluted EPS (from continuing operations), Organic Sales Growth, and Free Cash Flow (collectively, “non-GAAP financial measures”), which are intended to supplement the reported GAAP results. Management utilizes these non-GAAP financial measures as part of its internal reviews for purposes of monitoring, evaluating and forecasting the Company’s financial performance, communicating operating results to the Company’s Board of Directors and assessing related employee compensation measures. Management believes that such non-GAAP financial measures may be helpful to investors in assessing the Company’s overall financial performance, trends and period-over-period comparative results, in addition to the reasons noted later within this press release. Non-GAAP financial measures related to operating income, operating margin, net income from continuing operations attributable to Amphenol Corporation, effective tax rate and diluted EPS (from continuing operations) exclude income and expenses that are not directly related to the Company’s operating performance during the periods presented. Items excluded in the presentation of these non-GAAP financial measures in any period may consist of, without limitation, acquisition-related expenses, refinancing-related costs, and certain discrete tax items including but not limited to (i) the excess tax benefits related to stock-based compensation and (ii) the impact of significant changes in tax law. All non-GAAP financial measures and their most directly comparable U.S. GAAP financial measures presented within this press release are on a continuing operations basis only and exclude any results associated with discontinued operations. Non-GAAP financial measures related to net sales exclude the impact related to foreign currency exchange and acquisitions. Reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures are included at the end of this press release. However, such non-GAAP financial measures should not be considered in isolation, as a substitute for or superior to the related U.S. GAAP financial measures. In addition, these non-GAAP financial measures are not necessarily the same or comparable to similar measures presented by other companies as such measures may be calculated differently or may exclude different items. The non-GAAP financial measures are defined within the “Supplemental Financial Information” table at the end of this press release and should be read in conjunction with the Company’s financial statements presented in accordance with U.S. GAAP.

Although the Company believes the expectations reflected in all forward-looking statements, including those regarding first quarter 2022 sales and Adjusted Diluted EPS, among other matters, are based upon reasonable assumptions, the expectations may not be attained or there may be material deviation. Readers and investors are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made.

There are risks and uncertainties that could cause actual results to differ materially from these forward-looking statements, which include, but are not limited to, the following: political, economic, military and other risks related to operating in countries outside the United States, as well as changes in general economic conditions, geopolitical conditions, U.S. trade policies and other factors beyond the Company’s control; future risks and existing uncertainties associated with adverse public health developments, including epidemics and pandemics such as the COVID-19 pandemic, which continues to disrupt our operations including, depending on the specific location, government regulations that inhibit our ability to operate certain of our facilities in the ordinary course, travel restrictions, supplier constraints, supply-chain interruptions, logistics challenges and limitations, labor disruptions and reduced demand from certain customers; uncertainties associated with a protracted economic slowdown that could negatively affect the financial condition of our customers; risks associated with our inability to obtain certain raw materials and components in the current challenging supply chain environment, as well as the risk that the cost of most of the Company’s raw materials and components is increasing; negative impacts caused by extreme weather conditions and natural catastrophic events, including those caused by climate change and global warming; risks associated with the improper conduct by any of our employees, customers, suppliers, distributors or any other business partners which could impair our business reputation and financial results and could result in our non-compliance with anti-corruption laws and regulations of the U.S. government and various foreign jurisdictions; changes in exchange rates of the various currencies in which the Company conducts business; risks associated with write-downs related to inventories that may become obsolete or for which we may have supply in excess of anticipated demand, as well as long-lived assets for which events or circumstances may arise that could indicate impairment; the risks associated with the Company’s dependence on attracting, recruiting, hiring and retaining skilled employees, including as part of our various management teams; the Company’s dependence on sales to the communications industry, which markets are dominated by large manufacturers and operators who regularly exert significant pressure on suppliers, including the Company; changes in defense expenditures in the military market, including the impact of reductions or changes in the defense budgets of U.S. and foreign governments; risks and difficulties in trying to compete successfully on the basis of technology innovation, product quality and performance, price, customer service and delivery time;

risks associated with the Company’s inability to access the global capital markets on favorable terms, including as a result of significant deterioration of general economic or capital market conditions, or as a result of a downgrade in the Company’s credit rating; cybersecurity threats, including but not limited to malware, phishing, credential harvesting, ransomware and other increasingly sophisticated attacks, that could impair our information technology systems and could disrupt business operations, result in the loss of or inability to access confidential information and critical business, financial or other data, and/or cause the release of highly sensitive confidential information, any of which could adversely impact our reputation and operating results and potentially lead to litigation and/or governmental investigations and fines; government contracting risks that the Company may be subject to, including laws and regulations governing performance of government contracts and related risks associated with conducting business with the U.S. and other foreign government or their suppliers (both directly and indirectly); governmental export and import controls that certain of our products may be subject to, including export licensing, customs regulations, economic sanctions and other laws; changes in fiscal and tax policies, audits and examinations by taxing authorities, laws, regulations and guidance in the United States and foreign jurisdictions; any difficulties in protecting the Company’s intellectual property rights; litigation, customer claims, product recalls, governmental investigations, criminal liability or environmental matters including changes to laws and regulations to which the Company may be subject; and incremental costs and other risks that may arise in connection with regulatory efforts to combat the negative effects of climate change. In addition, the extent to which the COVID-19 pandemic will continue to impact our business and financial results going forward will be dependent on future developments such as the length and severity of the crisis, the impact of the recent resurgence of the crisis due to the Omicron variant as well as any additional future resurgences from known or new variants, future government regulations and actions in response to the crisis, the timing, availability, effectiveness and adoption rates of vaccines and treatments, and the overall impact of the COVID-19 pandemic on the global economy and capital markets, among many other factors, all of which remain highly uncertain and unpredictable.

These or other uncertainties may cause the Company’s actual future results to be materially different from those expressed in any forward-looking statements. The Company undertakes no obligation to update or revise any forward-looking statements except as required by law.
