All Rights Reserved. 2#3Disclaimer This presentation and the accompanying oral presentation have been prepared by Amplitude, Inc. (the "Company"). Certain statements in this presentation and the accompanying oral commentary are forward-looking statements. These statements relate to the Company's financial outlook for the first quarter of 2023 and full year 2023, the expected performance of the Company's products, the Company's expected quarterly and long-term growth, investments, and overall future prospects, as well as its business strategy and plans and objectives for future operations, and are subject to a number of known and unknown risks, uncertainties, and other factors that may cause the actual results, levels of activity, performance, or achievements of the Company or its industry to be materially different from those expressed or implied by any forward-looking statements. In some cases, forward-looking statements can be identified by words such as "may," "should," "could," "predict," "potential," "believe," "expect," "continue," "will," "anticipate," "seek," "estimate," "intend," "plan," "projection," "would," and "outlook," or the negative version of those words or phrases or other comparable words or phrases of a future- or forward-looking nature. 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. These risks and uncertainties include, but are not limited to, those set forth herein as well as in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 being filed at or around the date hereof, and other risks and uncertainties listed from time to time in the Company's other filings with the U.S. Securities and Exchange Commission. Moreover, the Company operates in a competitive, new, and rapidly changing market, and new risks may emerge from time to time. It is not possible for the Company 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. The forward-looking statements in this presentation are made only as of the date hereof. 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 to conform these statements to actual results or revised expectations. This presentation also contains estimates and other statistical data made by third 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 third 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. This presentation also includes certain non-GAAP financial measures (including on a forward-looking basis) such as Free Cash Flow, Free Cash Flow Margin, non-GAAP Gross Margin, non-GAAP Loss from Operations, non-GAAP Operating Margin, non-GAAP Sales and Marketing Expenses, non-GAAP Research and Development Expenses, non-GAAP General and Administrative Expenses, and non-GAAP Net Loss Per Share. 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.

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. © 2023 Amplitude Inc.
