2 Forward - Looking Statements This communication contains “forward - looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Sec tion 21E of the Securities Exchange Act of 1934 that are not historical facts, and involve risks and uncertainties that could cause actual results of Grid Dynamics to d iff er materially from those expected and projected. These forward - looking statements can be identified by the use of forward - looking terminology, including the words “believes,” “estimat es,” “anticipates,” “expects,” “intends,” “plans,” “may,” “will,” “potential,” “projects,” “predicts,” “continue,” or “should,” or, in each case, their negative or other variat ion s or comparable terminology. These forward - looking statements include, without limitation, statements concerning Grid Dynamics’ expectations with respect to future performance, ma rket size and industry trends. These forward - looking statements involve significant risks and uncertainties that could cause the actual results to differ mater ially from the expected results. Most of these factors are outside Grid Dynamics’ control and are difficult to predict. Factors that may cause such differences include, but are not li mited to: ( i ) the inability to maintain the listing of the shares of common stock of Grid Dynamics on The NASDAQ Stock Market; (ii) the ability of Grid Dynamics to grow and manage grow th profitably and retain its key employees; (iv) costs related to being a public company; (v) changes in applicable laws or regulations; (vi) the possibility that Grid Dynami cs may be adversely affected by other economic, business, and/or competitive factors, including as a result of economic and operational impacts of the recent outbreak of the co ronavirus (commonly referred to as COVID - 19); and (vii) other risks and uncertainties as specified in Grid Dynamics’ filings with the SEC, including those under the sectio ns entitled “Risk Factors.” Grid Dynamics cautions that the foregoing list of factors is not exclusive. Grid Dynamics cautions readers not to place undue reliance upon any forward - looking statements, which speak only as of the date made. Grid Dynamics does not undertake any obligation to update any forward - looking statements to reflect any change in its expectatio ns or any change in events, conditions or circumstances on which any such statement is based. Use of Projections This presentation contains projections for Grid Dynamics, including with respect to its Adjusted EBITDA and revenue. Grid Dyn ami cs’ auditors have not audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this presentation, an d accordingly, have not expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this presentation. These projections are for ill ust rative purposes only and should not be relied upon as necessarily indicative of future results. In this presentation, certain of the above - mentioned projection information has bee n repeated for purposes of providing comparisons with historical data. The assumptions and estimates underlying the projected information are inherently uncertain and are sub jec t to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in th e projected information. Accordingly, there can be no assurance that the projected results will be indicative of the future performance of Grid Dynamics or that actual results wil l not differ materially from those presented in the projected information. Industry and Market Data This presentation includes market data and other statistical information for sources believed by Grid Dynamics to be reliable , i ncluding independent industry publications and other published independent sources. Some data are also based on the good faith estimates of Grid Dynamics, which are derived fr om their review of internal sources as well as the independent sources described above. Although Grid Dynamics believe these sources are reliable, they have not independent ly verified the information and cannot guarantee its accuracy and completeness. Non - GAAP Financial Measures In this presentation, Grid Dynamics supplements results reported in accordance with United States generally accepted accounti ng principles, referred to as GAAP, with non - GAAP financial measures, including Adjusted EBITDA. Management believes these measures help illustrate underlying trends in Grid D yna mics’ business and uses the measures to establish budgets and operational goals, communicate internally and externally, for managing its business and evaluating its per formance, including in comparison to prior periods. Adjusted EBITDA is defined as Earnings Before Interest, Taxes, Depreciation and Amortization, and excludes transacti on expenses and stock - based compensation expenses. Adjusted EBITDA is not a measure of financial performance under GAAP and should not be considered as an alternative to , or more meaningful than, income from operations as a measure of operating performance or to cash flows from operating, investing or financing activities or as a m eas ure of liquidity. Reconciliations of the differences between the non - GAAP measures to the comparable GAAP financial measures are included in this presentation. Grid Dynamics anticip ates that it will continue to report certain non - GAAP financial measures in its financial results, including non - GAAP results that exclude stock - based compensation expense, acquisition - related charges, impairment of goodwill, amortization of certain intangible assets, items related to one - time charges and benefits, gains and losses related to foreign exchange, and the tax impact of any such pre - tax adjustments. Because these non - GAAP financial measures are not calculated in accordance with GAAP, these measures are no t comparable to GAAP and may not be comparable to similarly described non - GAAP measures reported by other companies within Grid Dynamics’ industry. Consequently, G rid Dynamics’ non - GAAP financial measures should not be evaluated in isolation or supplant comparable GAAP measures, but should be considered together with the informa tio n in Grid Dynamics’ consolidated financial statements, which are prepared in accordance with GAAP.
