Non-GAAP Financial Measures

PROS has provided in this release certain non-GAAP financial measures, including non-GAAP gross profit and margin, non-GAAP income (loss) from operations or non-GAAP operating income (loss), annual recurring revenue, adjusted EBITDA, free cash flow, non-GAAP tax rate, non-GAAP net income (loss), and earnings (loss) per share or non-GAAP earnings (loss) per share. PROS uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating PROS’ ongoing operational performance and cloud transition. Non-GAAP gross margin can be compared to gross margin which can be calculated from the condensed consolidated statements of loss by dividing gross profit by total revenue. Non-GAAP gross margin is similarly calculated but first adds back to gross profit the portion of certain of the non-GAAP adjustments described below attributable to cost of revenue. Non-GAAP subscription margin can be compared to subscription margin which can be calculated from the condensed consolidated statements of loss by dividing subscription gross profit (subscription revenue minus subscription cost) by subscription revenue. Non-GAAP subscription margin is similarly calculated but first subtracts out from subscription cost the portion of certain of the non-GAAP adjustments described below attributable to cost of subscription. These items and amounts are presented in the Supplemental Schedule of Non-GAAP Financial Measures.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measure as detailed above. A reconciliation of GAAP to the non-GAAP financial measures has been provided in the tables included as part of this press release, and can be found, along with other financial information, in the investor relations portion of our website. PROS' use of non-GAAP financial measures may not be consistent with the presentations by similar companies in PROS' industry. PROS has also provided in this release certain forward-looking non-GAAP financial measures, including non-GAAP income (loss) from operations, annual recurring revenue, non-GAAP earnings (loss) per share, adjusted EBITDA, free cash flow, non-GAAP tax rates, and calculated billings (collectively the "non-GAAP financial measures") as follows:

Non-GAAP income (loss) from operations: Non-GAAP income (loss) from operations excludes the impact of share-based compensation, amortization of acquisition-related intangibles and severance. Non-GAAP income (loss) from operations excludes the following items from non-GAAP estimates:

• Share-Based Compensation: Although share-based compensation is an important aspect of compensation for our employees and executives, our share-based compensation expense can vary because of changes in our stock price and market conditions at the time of grant, varying valuation methodologies, and the variety of award types. Since share-based compensation expense can vary for reasons that are generally unrelated to our performance during any particular period, we believe this could make it difficult for investors to compare our current financial results to previous and future periods. Therefore, we believe it is useful to exclude share-based compensation in order to better understand our business performance and allow investors to compare our operating results with peer companies.

• Amortization of Acquisition-Related Intangibles: We view amortization of acquisition-related intangible assets, such as the amortization of the cost associated with an acquired company's research and development efforts, trade names, customer lists and customer relationships, as items arising from pre-acquisition activities determined at the time of an acquisition. While these intangible assets are continually evaluated for impairment, amortization of the cost of purchased intangibles is a static expense, one that is not typically affected by operations during any particular period.

• Severance: Severance costs relate to the separation of our Chief Operations Officer in Q1 2022 and costs related to other internal role consolidations as well as severance cost incurred in Q4 2022 as the Company reprioritized its investments to focus on supporting key growth areas of its business. As a result of this reprioritization, the Company incurred severance, employee benefits, outplacement and related costs. These amounts are unrelated to our core performance during any particular period, and therefore, we believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies.

Non-GAAP earnings (loss) per share: Non-GAAP net income (loss) excludes the items listed above as excluded from non-GAAP income (loss) from operations and also excludes amortization of debt issuance costs, loss (gain) on equity investments, net and the taxes related to these items and the items excluded from non-GAAP income (loss) from operations. Estimates of non-GAAP earnings (loss) per share are calculated by dividing estimates for non-GAAP net income (loss) by our estimate of weighted average shares outstanding for the future period. In addition to the items listed above as excluded from non-GAAP income (loss) from operations, non-GAAP net income (loss) excludes the following items from non-GAAP estimates:

• Amortization of Debt Issuance Costs: Amortization of debt issuance costs are related to our convertible notes. These amounts are unrelated to our core performance during any particular period, and therefore, we believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies.

• Loss (Gain) on Equity Investments, net: Loss (gain) on equity investments, net relate to observable price changes for equity investments without a readily determinable fair value identified during the quarters ended September 30, 2022 and December 31, 2022, including other-than-temporary loss. These amounts are unrelated to our core performance during any particular period, and therefore, we believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies.

• Taxes: We exclude the tax consequences associated with non-GAAP items to provide investors with a useful comparison of our operating results to prior periods and to our peer companies because such amounts can vary significantly. In the fourth quarter of 2014, we concluded that it is more likely than not that we will be unable to fully realize our deferred tax assets and accordingly, established a valuation allowance against those assets. The ongoing impact of the valuation allowance on our non-GAAP effective tax rate has been eliminated to allow investors to better understand our business performance and compare our operating results with peer companies.

Annual Recurring Revenue: Annual Recurring Revenue ("ARR") is used to assess the trajectory of our cloud business. ARR means, as of a specified date, the contracted recurring revenue, including contracts with a future start date, together with annualized overage fees incurred above contracted minimum transactions, and excluding perpetual and term license agreements. ARR should be viewed independently of revenue and any other GAAP measure. Subscription ARR is calculated in the same manner, but excludes maintenance and support ARR.

Non-GAAP Tax Rate: The estimated non-GAAP effective tax rate adjusts the tax effect to quantify the impact of the excluded non-GAAP items.

Adjusted EBITDA: Adjusted EBITDA is defined as GAAP net income (loss) before interest expense, provision for income taxes, depreciation and amortization, as adjusted to eliminate the effect of stock-based compensation cost, severance, amortization of acquisition-related intangibles, and depreciation and amortization. Adjusted EBITDA should not be considered as an alternative to net income (loss) as an indicator of our operating performance.

Free Cash Flow: Free cash flow is a non-GAAP financial measure which is defined as net cash provided by (used in) operating activities, excluding severance payments, less capital expenditures (excluding expenditures for PROS new headquarters), purchases of other (non-acquisition-related) intangible assets and capitalized internal-use software development costs.

Calculated Billings: Calculated billings is defined as total subscription, maintenance and support revenue plus the change in recurring deferred revenue in a given period.

These non-GAAP estimates are not measurements of financial performance prepared in accordance with GAAP, and we are unable to reconcile these forward-looking non-GAAP financial measures to their directly comparable GAAP financial measures because the information described above which is needed to complete a reconciliation is unavailable at this time without unreasonable effort.
