These forward-looking statements are not statements of historical fact, and are based on current expectations, estimates, and projections about the Company's industry as well as certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond the Company's control. While the Company believes that these expectations, assumptions, estimates and projections are reasonable, such forward-looking statements are only predictions and involve known and unknown risk and uncertainties, and so you are cautioned not to give undue weight to such forward-looking statements. Moreover, the Compar tes in a competitive, new and rapidly changing market, and new risks may emerge from time to time. It is not possible for the mpany to predict all risks, nor can it assess the impact of all factors on its business or the extent to which any factor, or combination of factors, may cause actual results or outcomes to differ materially from those contained in any forward-looking statements it may make.

Except to the extent required by law, the Company assumes no obligation and does not intend to update any of these forward-looking statements after the date of this presentation or conform these statements to actual results or revised expectations. This presentation also contains estimates and other statistical data made by independent parties and by the Company relating to market size and growth and other data about the Company's industry. These estimates and other statistical data involve a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates and other statistical data. The Company has not independently verified the statistical and other industry data generated by independent parties and contained in this presentation and, accordingly, it cannot guarantee their accuracy or completeness. In addition, expectations, assumptions, estimates and projections of the Company's future performance and the future performance of the markets in which the Company operates are necessarily subject to a high degree of uncertainty and risk.

These non-GAAP financial measures are in addition to, and not as a substitute for or superior to measures of financial performance prepared in accordance with GAAP. There are a number of limitations related to the use of these non-GAAP financial measures versus their nearest GAAP equivalents. For example, other companies may calculate non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of the Company's non-GAAP financial measures as tools for comparison. The Company has provided a reconciliation of those historic measures to the most directly comparable GAAP measures, which is available in the appendix to this presentation.

Gross margin, operating margin and free cash flow margin are calculated as gross margin, operating margin and free cash flow, respectively, divided by total revenue. A reconciliation of GAAP to non-GAAP results is available in the appendix of this presentation. ** The difference in share count is mainly attributed to preferred stock share conversions that occurred during the year. As these conversions occurred at the end of Q3'21, the related shares were included in weighted average common stock outstanding for only a portion of fiscal 2021, but the entirety of the fourth quarter.

For example, the non-GAAP adjustment for stock-based compensation expense requires additional inputs such as the number and value of awards granted that are not currently ascertainable, and the non-GAAP adjustment for amortization of acquired intangible assets depends on the timing and value of intangible assets acquired that cannot be accurately forecasted. 19#20Sell-Side Analyst Q&A#21GAAP-to-Non-GAAP Reconciliation#22A GAAP to Non-GAAP Reconciliation Reconciliation of gross profit and gross margin GAAP gross profit Plus: stock-based compensation expense and related employer payroll taxes Plus: amortization of acquired intangible assets Non-GAAP gross profit GAAP gross margin Non-GAAP adjustments Non-GAAP gross margin Reconciliation of operating loss and operating margin GAAP loss from operations Plus: stock-based compensation expense and related employer payroll taxes Plus: amortization of acquired intangible assets Plus: direct listing expenses Non-GAAP loss from operations GAAP operating margin Non-GAAP adjustments Non-GAAP operating margin Reconciliation of net loss GAAP net loss Plus: stock-based compensation expense and related employer payroll taxes Plus: amortization of acquired intangible assets Plus: direct listing expenses Non-GAAP net loss Reconciliation of net loss per share GAAP net loss per share, basic and diluted Non-GAAP adjustments to net loss Non-GAAP net loss per share, basic and diluted Weighted average shares used in GAAP and non-GAAP per share calculation, basic and diluted Note: Certain figures may not sum due to rounding © 2021 Amplitude Inc.
