EPAM supplements results reported in accordance with United States generally accepted accounting principles, referred to as GAAP, with non-GAAP financial measures. Management believes these measures help illustrate underlying trends in EPAM’s business and uses the measures to establish budgets and operational goals, communicate internally and externally, for managing EPAM’s business and evaluating its performance. Management also believes these measures help investors compare EPAM’s operating performance with its results in prior periods. EPAM anticipates that it will continue to report both GAAP and certain non-GAAP financial measures in its financial results, including non-GAAP results that exclude stock-based compensation expenses, acquisition-related costs including amortization of acquired intangible assets, impairment of assets, expenses associated with EPAM's humanitarian commitment to its professionals in Ukraine, employee separation costs incurred in connection with restructuring programs, certain other one-time charges and benefits, changes in fair value of contingent consideration, foreign exchange gains and losses, excess tax benefits and tax shortfalls related to stock-based compensation, and the related effect on income taxes of the pre-tax adjustments. Management also compares revenues on an “organic constant currency basis,” which is a non-GAAP financial measure. This measure excludes the effect of acquisitions by removing revenues from an acquired company in the twelve months after completing an acquisition and foreign currency exchange rate fluctuations by translating current period revenues into U.S. dollars at the weighted average exchange rates of the prior period of comparison. Because EPAM’s reported non-GAAP financial measures are not calculated in accordance with GAAP, these measures are not comparable to GAAP and may not be comparable to similarly described non-GAAP measures reported by other companies within EPAM’s industry. Consequently, EPAM’s non-GAAP financial measures should not be evaluated in isolation or supplant comparable GAAP measures, but rather, should be considered together with the information in EPAM’s consolidated financial statements, which are prepared in accordance with GAAP.

This press release includes estimates and statements which may constitute forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, the accuracy of which are necessarily subject to risks, uncertainties, and assumptions as to future events that may not prove to be accurate. Our estimates and forward-looking statements are mainly based on our current expectations and estimates of future events and trends, which affect or may affect our business and operations. These statements may include words such as “may,” “will,” “should,” “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate”or similar expressions. Those future events and trends may relate to, among other things, developments relating to the war in Ukraine and escalation of the war in the surrounding region, political and civil unrest or military action in the geographies where we conduct business and operate, difficult conditions in global capital markets, foreign exchange markets, global trade and the broader economy, the adoption and implementation of artificial intelligence technologies by EPAM and its clients, and the effect that these events may have on client demand and our revenues, operations, access to capital, and profitability. Other factors that could cause actual results to differ materially from those expressed or implied include general economic conditions, the risk factors discussed in the Company's most recent Annual Report on Form 10-K and the factors discussed in the Company's Quarterly Reports on Form 10-Q, particularly under the headings “Management's Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors”and other filings with the Securities and Exchange Commission.

Reconciliation of year-over-year revenue growth as reported on a GAAP basis to revenue growth on an organic constant currency basis is presented in the table below:

Reconciliation of various income statement amounts from GAAP to non-GAAP for the three months ended March 31, 2026 and 2025:

(a)Humanitarian support in Ukraine includes expenses related to EPAM's $100 million humanitarian commitment in response to Russia's invasion of Ukraine to support EPAM professionals and their families in and displaced from Ukraine. These expenses are incremental to those expenses incurred prior to the crisis, clearly separable from normal operations, and not expected to recur once the crisis has subsided and operations return to normal.

(b)Cost Optimization charges include employee separation costs incurred in connection with the programs initiated in the second quarter of 2024 and second quarter of 2025. Consistent with the Company's historical non-GAAP policy, costs incurred in connection with formal restructuring initiatives have been excluded from non-GAAP results as these are attributable to targeted restructuring efforts and not expected to recur once the respective Cost Optimization program is completed.

(c)Net discrete benefit related to the implementation of tax planning to disregard certain foreign subsidiaries as separate entities for U.S. income tax purposes. Consistent with the Company's historical non-GAAP policy, the benefit related to the implementation of tax planning has been excluded from non-GAAP results as it is one-time and unusual in nature.

The below guidance constitutes forward-looking statements within the meaning of the federal securities laws and is based on a number of assumptions that are subject to change and many of which are outside the control of the Company. Actual results may differ materially from the Company’s expectations depending on factors discussed in the Company’s filings with the Securities and Exchange Commission.

Reconciliation of expected year-over-year revenue growth on a GAAP basis to expected revenue growth on an organic constant currency basis is presented in the table below:

(d)EPAM has not included the impact of potential future one-time charges including asset impairments, unusual gains and losses, expenses incurred in connection with future cost optimization actions, and other acquisition-related expenses because the Company is unable to predict these amounts with reasonable certainty.
