BUSINESS AND SUMMARY OF SIGNIFI

BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3 Months Ended

Accounting Policies [Abstract]
BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES EPAM Systems, Inc. (the “Company” or “EPAM”) is a leading digital transformation services and product engineering company, providing digital platform engineering and software development services to customers located around the world, primarily in North America, Europe, and Asia. The Company’s industry expertise includes financial services, travel and consumer, software and hi-tech, business information and media, life sciences and healthcare, as well as several other industries. The Company is incorporated in Delaware with headquarters in Newtown, Pennsylvania. Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of EPAM have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP” or “U.S. GAAP”) and Article 10 of Regulation S-X under the Securities Exchange Act of 1934, as amended. The unaudited condensed consolidated financial statements include the financial statements of EPAM Systems, Inc. and its subsidiaries with all intercompany balances and transactions eliminated. These unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2021 included in its Annual Report on Form 10-K. The preparation of these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates, and such differences may be material to the unaudited condensed consolidated financial statements. Operating results for the interim periods are not necessarily indicative of results that may be expected to occur for the entire year. In management’s opinion, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position as of March 31, 2022 and the results of its operations and its cash flows for the periods presented. Risks and Uncertainties — As a result of its global operations, the Company may be subject to certain inherent risks. Concentration of Credit — Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents, short-term investments and trade receivables. The Company maintains cash, cash equivalents and short-term investments with financial institutions. The Company believes its credit policies reflect normal industry terms and business risk and there is no expectation of non-performance by the counterparties. The Company has cash in several countries, including Russia, Ukraine and Belarus, which could be impacted by the invasion of Ukraine (see Note 2, “Impact of the Invasion of Ukraine”) and where the banking sector remains subject to periodic instability, banking and other financial systems generally do not meet the banking standards of more developed markets, and bank deposits made by corporate entities are not insured. As of March 31, 2022, the Company had $59.5 million of cash and cash equivalents in banks in Russia, $51.0 million of cash and cash equivalents in banks in Belarus, and $28.3 million of cash and cash equivalents in banks in Ukraine. Also, as of March 31, 2022, the Company had an additional $28.9 million of cash in a bank in Belarus which could not be accessed due to an administrative review by the bank. Based on the inability to access this $28.9 million of cash on demand, the Company has classified this amount as restricted cash included in Prepaid and other current assets in its condensed consolidated balance sheets as of March 31, 2022. These funds were made available to EPAM in full during April and substantially all of these funds were transferred to another bank in the country. The Company places its cash and cash equivalents with financial institutions considered stable in the region, limits the amount of credit exposure with any one financial institution and conducts ongoing evaluations of the credit worthiness of the financial institutions with which it does business. A banking crisis, bankruptcy or insolvency of banks that process or hold the Company’s funds, or sanctions may result in the loss of deposits or adversely affect the Company’s ability to complete banking transactions, which could adversely affect the Company’s business and financial condition. Cash in these countries is used for the operational needs of the local entities and cash balances change with the expected operating needs of these entities. The Company regularly monitors cash held in these countries and, to the extent the cash held exceeds amounts required to support its operations in these countries, the Company distributes the excess funds into markets with more developed banking sectors. Trade receivables are generally dispersed across many customers operating in different industries; therefore, concentration of credit risk is limited. Historically, credit losses and write-offs of trade receivables have not been material to the consolidated financial statements. If any of our customers enter bankruptcy protection or otherwise take steps to alleviate their financial distress, the Company’s credit losses and write-offs of trade receivables could increase, which would negatively impact its results of operations. See Note 2 “Impact of the Invasion of Ukraine” for further discussion regarding trade receivables and contract assets from customers located in Russia. Foreign currency risk — The Company’s global operations are conducted predominantly in U.S. dollars. Other than U.S. dollars, the Company generates revenues in various currencies, principally, euros, British pounds, Russian rubles, Swiss francs, and Canadian dollars and incurs expenditures principally in Russian rubles, Polish zlotys, euros, Swiss francs, Hungarian forints, British pounds, Indian rupees, Chinese yuan renminbi and Mexican pesos. The Company’s international operations expose it to foreign currency exchange rate changes that could impact translations of foreign denominated assets and liabilities into U.S. dollars and future earnings and cash flows from transactions denominated in different currencies. The Company is exposed to fluctuations in foreign currency exchange rates primarily related to trade receivables from sales in foreign currencies and cash outflows for expenditures in foreign currencies. The Company’s results of operations, primarily revenues and expenses denominated in foreign currencies, can be affected if any of the currencies which are used materially in the Company’s business, appreciate or depreciate against the U.S. dollar. The Company has a hedging program whereby it entered into a series of foreign exchange forward contracts with durations of twelve months or less that are designated as cash flow hedges of forecasted Russian ruble, Polish zloty, Indian rupee and Hungarian forint transactions. See Note 6, “Derivative Financial Instruments ” for further discussion regarding the Company’s termination of the hedging program for the Russian ruble. Interest rate risk — The Company’s exposure to market risk is influenced by the changes in interest rates received on cash and cash equivalent deposits and short-term investments and paid on any outstanding balance on the Company’s borrowings, mainly under the 2021 Credit Agreement, which is subject to a variety of rates depending on the type and timing of funds borrowed (See Note 8 “Debt”). The Company does not believe it is exposed to material direct risks associated with changes in interest rates related to these deposits and borrowings. Adoption of New Accounting Standards There were no recently adopted accounting standards which had a material impact on the Company’s consolidated financial position, results of operations, changes in stockholders’ equity and cash flows. Pending Accounting Standards From time to time, new accounting pronouncements are issued by the FASB or other standards-setting bodies that the Company will adopt according to the various timetables the FASB specifies. The Company believes the impact of recently issued standards that are not yet effective will not have a material impact on its consolidated financial position, results of operations and cash flows upon adoption.

IMPACT OF THE INVASION OF UKRAI

IMPACT OF THE INVASION OF UKRAINE	3 Months Ended

Discontinued Operations and Disposal Groups [Abstract]
IMPACT OF THE INVASION OF UKRAINE	IMPACT OF THE INVASION OF UKRAINEOn February 24, 2022, Russian forces attacked Ukraine and its people and EPAM has called for an immediate end to this unlawful and unconscionable attack. As of March 31, 2022, the Company had $74.9 million of Property and equipment, net in Ukraine consisting of a building classified as construction-in-progress located in Kyiv with a net book value of $50.4 million, laptops with a net book value of $15.3 million, most of which are in the possession of employees, various office furniture, equipment and supplies with a net book value of $8.5 million, and leasehold improvements located throughout Ukraine with a net book value of $0.7 million. Additionally, the Company had Operating lease right-of-use assets located throughout Ukraine with a net book value of $18.8 million as of March 31, 2022. Through the issuance date of these interim financial statements, the Company is not aware of any damage to its long-lived assets in Ukraine and the Company expects to continue to use these assets as part of its global delivery model. On March 4, 2022, in addition to the Company’s donations, and the work of EPAM volunteers on the ground, the Company announced a $100.0 million humanitarian commitment to support its employees and their families in and displaced from Ukraine. During the three months ended March 31, 2022, the Company expensed $25.7 million related to this commitment including special cash payments to support impacted employees, financial and medical support for impacted families, travel, meals and lodging expenses, and donations to third-party humanitarian organizations. Of this expensed amount, $19.2 million is classified in Cost of revenues (exclusive of depreciation and amortization) and $6.5 million is classified in Selling, general and administrative expense on the condensed consolidated financial statements for the three months ended March 31, 2022. In response to the attacks on Ukraine, EPAM announced on March 4, 2022, it would discontinue services to customers located in Russia. Based on this change in facts and circumstances, the long-term cash flow forecast for the Company’s operations in Russia and its Russia reporting unit were significantly reduced. The reduction in the long-term cash flow forecasts indicated that the carrying amounts of goodwill and long-lived assets associated with the Company’s Russia reporting unit and operations in Russia may not be recoverable, and the carrying value of these assets was tested for impairment. The Company relied on the income approach to estimate the fair values of the Russia reporting unit and long-lived assets and considered multiple scenarios including the continuing operation and exit of operations in Russia. Reflecting the negative long-term cash flow forecasts associated with these assets that each of these scenarios produced, during the three months ended March 31, 2022, the Company recorded impairments of Property and equipment, net of $15.1 million, Operating lease right-of-use assets, net of $3.8 million, and Goodwill of $0.7 million. These asset impairment charges are included in Selling, general and administrative expenses in the interim condensed consolidated financial statements. Additionally, the Company evaluated trade receivables and contract assets for estimated future credit losses from customers located in Russia and recorded a bad debt expense of $8.4 million, reflecting the deterioration of creditworthiness of its customers in Russia during the three months ended March 31, 2022. This expense is included in Selling, general and administrative expenses in the condensed consolidated financial statements. Furthermore, in response to the invasion, the Company began executing its business continuity plans focused on relocating employees residing in Ukraine, Belarus and Russia to other countries as well as assigning delivery personnel in locations outside of the region to serve in unbilled standby or backup capacity to ensure the continuity of delivery for its customers who have substantial delivery exposure to Ukraine or other delivery concerns resulting from the invasion. In addition to costs incurred as part of EPAM’s humanitarian commitment to Ukraine, during the three months ended March 31, 2022, the Company incurred expenses of $18.7 million classified as Selling, general and administrative expenses related to its geographic repositioning efforts and $2.6 million classified as Cost of revenues (exclusive of depreciation and amortization) related to these standby resources. The Company also recorded an impairment charge of $1.3 million classified as Other income/(expense) related to a financial asset in Ukraine which the Company believes is unrealizable due to the events in Ukraine.

FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The Company carries certain assets and liabilities at fair value on a recurring basis on its condensed consolidated balance sheets. The following tables present the fair values of the Company’s financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021: As of March 31, 2022 Balance Level 1 Level 2 Level 3 Foreign exchange derivative assets $ 145 $ — $ 145 $ — Rights to acquire noncontrolling interest in consolidated subsidiaries 1,066 — — 1,066 Total assets measured at fair value on a recurring basis $ 1,211 $ — $ 145 $ 1,066 Foreign exchange derivative liabilities $ 47,733 $ — $ 47,733 $ — Contingent consideration 27,992 — — 27,992 Total liabilities measured at fair value on a recurring basis $ 75,725 $ — $ 47,733 $ 27,992 As of December 31, 2021 Balance Level 1 Level 2 Level 3 Foreign exchange derivative assets $ 1,429 $ — $ 1,429 $ — Rights to acquire noncontrolling interest in consolidated subsidiaries 6,093 — — 6,093 Total assets measured at fair value on a recurring basis $ 7,522 $ — $ 1,429 $ 6,093 Foreign exchange derivative liabilities $ 5,849 $ — $ 5,849 $ — Contingent consideration 23,114 — — 23,114 Total liabilities measured at fair value on a recurring basis $ 28,963 $ — $ 5,849 $ 23,114 The foreign exchange derivatives are valued using pricing models and discounted cash flow methodologies based on observable foreign exchange data at the measurement date. See Note 6 “Derivative Financial Instruments” in the condensed consolidated interim financial statements for additional information regarding derivative financial instruments. As part of the acquisition of Emakina, the Company acquired rights to purchase certain noncontrolling interests in consolidated subsidiaries of Emakina in exchange for future cash payments determined by the future profitability of certain subsidiaries. The Company determines the fair value of these rights by (i) estimating the fair value of the noncontrolling interests in consolidated subsidiaries by applying an EBITDA multiple adjusted for a lack of control and marketability, less (ii) the fair value of expected future payments to settle the related contractual obligations. The Company purchased the majority of the noncontrolling interest in consolidated subsidiaries during the first quarter of 2022. The Company determines the fair value of the contingent consideration liabilities using Monte Carlo simulations or probability-weighted expected return methods. The fair value of the contingent consideration for the PolSource acquisition attributable to future revenues and earnings was measured utilizing a Monte Carlo simulation, based on future revenue and earnings projections of the business, revenue volatility and asset volatility of comparable companies, and a discount rate. The discount rate used to determine the fair value of this contingent consideration was 0.4% as of the acquisition date. The fair value of the contingent consideration for the PolSource acquisition attributable to future operating metrics was measured using a probability-weighted expected return method, based on the expected future payments using the earnout formula and performance targets specified in the purchase agreement and adjusting those estimates to reflect the probability of their achievement. The weighted-average estimated future payments were then discounted to present value using a rate based on EPAM’s cost of debt. The discount rate used to determine the fair value of this contingent consideration was 0.4% as of the acquisition date. The fair value of the contingent consideration for all other acquisitions was determined using a probability-weighted expected return method and is based on the expected future payments to be made to the sellers of the acquired businesses in accordance with the provisions outlined in the respective purchase agreements. Although there is significant judgment involved, the Company believes its estimates and assumptions are reasonable. In determining fair value, the Company considered a variety of factors, including future performance of the acquired businesses using financial projections developed by the Company and market risk assumptions that were derived for revenue growth and earnings before interest and taxes. The Company estimated future payments using the earnout formula and performance targets specified in the purchase agreements and adjusted those estimates to reflect the probability of their achievement. Those weighted-average estimated future payments were then discounted to present value using a rate based on the weighted-average cost of capital of guideline companies. The discount rate used to determine the fair value of contingent consideration for the 2022 Acquisition was 13.0%. The discount rate used to determine the fair value of contingent consideration for the CORE acquisition was 13.0%. The discount rates used to determine the fair value of contingent consideration for the Other 2021 Acquisitions ranged from a minimum of 15.0% to a maximum of 22.0%. Changes in financial projections, market risk assumptions, discount rates or probability assumptions related to achieving the various earnout criteria would result in a change in the fair value of the recorded contingent liabilities. Such changes, if any, are recorded within Interest and other income, net in the Company’s condensed consolidated statement of income. A reconciliation of the beginning and ending balances of Level 3 acquisition-related contingent consideration using significant unobservable inputs for the three months ended March 31, 2022 is as follows: Amount Contingent consideration liabilities as of January 1, 2022 $ 23,114 Acquisition date fair value of contractual contingent liabilities - 2022 Acquisition 1,784 Changes in fair value of contingent consideration included in Interest and other (loss)/income, net 3,373 Effect of net foreign currency exchange rate changes (279) Contingent consideration liabilities as of March 31, 2022 $ 27,992 See Note 2, “Impact of the Invasion of Ukraine” for discussion of the nonrecurring level 3 fair value assessment used in the impairment tests of long-lived assets in Russia. Financial Assets and Liabilities Not Measured at Fair Value on a Recurring Basis Estimates of fair value of financial instruments not carried at fair value on a recurring basis on the Company’s condensed consolidated balance sheets are generally subjective in nature and are determined as of a specific point in time based on the characteristics of the financial instruments and relevant market information. The generally short maturities of certain assets and liabilities result in a number of assets and liabilities for which fair value equals or closely approximates the amount recorded on the Company’s condensed consolidated balance sheets. The following tables present the estimated fair values of the Company’s financial assets and liabilities not measured at fair value on a recurring basis as of the dates indicated: Fair Value Hierarchy Balance Estimated Fair Value Level 1 Level 2 Level 3 March 31, 2022 Financial Assets: Cash equivalents: Money market funds $ 63,817 $ 63,817 $ 63,817 $ — $ — Total cash equivalents $ 63,817 $ 63,817 $ 63,817 $ — $ — Restricted cash $ 31,464 $ 31,464 $ 31,464 $ — $ — Employee loans $ 922 $ 922 $ — $ — $ 922 Financial Liabilities: Short term debt $ 9,900 $ 9,900 $ — $ 9,900 $ — Borrowings under the 2021 Credit Agreement $ 25,000 $ 25,000 $ — $ 25,000 $ — Other long term debt $ 5,550 $ 5,550 $ — $ 5,550 $ — Fair Value Hierarchy Balance Estimated Fair Value Level 1 Level 2 Level 3 December 31, 2021 Financial Assets: Cash equivalents: Money market funds $ 78,302 $ 78,302 $ 78,302 $ — $ — Total cash equivalents $ 78,302 $ 78,302 $ 78,302 $ — $ — Restricted cash $ 2,722 $ 2,722 $ 2,722 $ — $ — Employee loans $ 818 $ 818 $ — $ — $ 818 Financial Liabilities: Short term debt $ 16,018 $ 16,018 $ — $ 16,018 $ — Borrowings under the 2021 Credit Agreement $ 25,000 $ 25,000 $ — $ 25,000 $ — Other long term debt $ 5,234 $ 5,234 $ — $ 5,234 $ — Non-Marketable Securities Without Readily Determinable Fair Values The Company holds investments in equity securities that do not have readily determinable fair values. These investments are recorded at cost and are remeasured to fair value based on certain observable price changes or impairment events as they occur. The carrying amount of these investments was $27.5 million and $27.5 million as of March 31, 2022 and December 31, 2021, respectively, and is classified as Other noncurrent assets in the Company’s condensed consolidated balance sheets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS In the normal course of business, the Company uses derivative financial instruments to manage the risk of fluctuations in foreign currency exchange rates. The Company has a hedging program whereby it enters into a series of foreign exchange forward contracts with durations of twelve months or less that are designated as cash flow hedges of forecasted Russian ruble, Polish zloty, Hungarian forint and Indian rupee transactions. As of March 31, 2022, all of the Company’s foreign exchange forward contracts, except the Russian ruble foreign exchange forward contracts, were designated as hedges and there is no financial collateral (including cash collateral) required to be posted by the Company related to the foreign exchange forward contracts. During the three months ended March 31, 2022, in response to the war in Ukraine, the Company de-designated its Russian ruble foreign exchange forward contracts as hedges and entered into offsetting foreign exchange forward contracts with the same counterparty. The Company determined it was probable the underlying forecasted foreign currency transactions which were hedged would not occur and reclassified the accumulated loss of $43.9 million on the underlying hedges into income which is classified as foreign exchange loss in the condensed consolidated statement of income. The fair value of derivative instruments on the Company’s condensed consolidated balance sheets as of March 31, 2022 and December 31, 2021 were as follows: As of March 31, 2022 As of December 31, 2021 Balance Sheet Classification Asset Derivatives Liability Derivatives Asset Derivatives Liability Derivatives Foreign exchange forward contracts - Prepaid expenses and other current assets $ 145 $ 1,429 Accrued expenses and other current liabilities $ 6,364 $ 5,849 Foreign exchange forward contracts - Accrued expenses and other current liabilities $ 41,369 $ —

Leases [Abstract]
LEASES	LEASES The Company leases office space, corporate apartments, office equipment, and vehicles. Many of the Company’s leases contain variable payments including changes in base rent and charges for common area maintenance or other miscellaneous expenses. Due to this variability, the cash flows associated with these variable payments are not included in the minimum lease payments used in determining the right-of-use assets and associated lease liabilities and are recognized in the period in which the obligation for such payments is incurred. The Company’s leases have remaining lease terms ranging from 0.1 to 9.8 years. Certain lease agreements, mainly for office space, include options to extend or terminate the lease before the expiration date. The Company considers such options when determining the lease term when it is reasonably certain that the Company will exercise that option. The Company leases and subleases a portion of its office space to third parties. Lease income and sublease income were immaterial for the three months ended March 31, 2022 and 2021. See Note 2, “Impact of the Invasion of Ukraine” for discussion of impairment of right-of-use assets in Russia.

Performance-Based Awards The table below summarizes activity related to the Company’s equity-classified performance-based awards for the three months ended March 31, 2022: Equity-Classified Equity-Settled Restricted Stock Equity-Classified Equity-Settled Restricted Stock Units Number of Shares Weighted Average Grant Date Number of Shares Weighted Average Grant Date Unvested performance-based awards outstanding at January 1, 2022 9 $ 165.87 23 $ 339.69 Awards granted — $ — 1 $ 556.68 Unvested performance-based awards outstanding at March 31, 2022 9 $ 165.87 24 $ 344.04 As of March 31, 2022, $0.6 million of total remaining unrecognized stock-based compensation cost related to performance-based equity-classified restricted stock is expected to be recognized over the weighted-average remaining requisite service period of 1.4 years. As of March 31, 2022, $4.7 million of total remaining unrecognized stock-based compensation cost related to performance-based equity-classified RSUs is expected to be recognized over the weighted-average remaining requisite service period of 3.0 years. 2021 Employee Stock Purchase Plan On November 1, 2021, the first offering period of the 2021 Employee Stock Purchase Plan ("ESPP") commenced. As of March 31, 2022, no purchases have been made under the ESPP as the first anticipated purchase date will be on April 29, 2022. The Company recognizes compensation expense related to shares issued pursuant to the ESPP on a straight-line basis over the six-month offering period. For the three months ended March 31, 2022, the Company recognized $1.7 million of stock-based compensation expense related to the ESPP. As of March 31, 2022, total unrecognized stock-based compensation cost related to the ESPP was $0.6 million, which is expected to be recognized over a period of 0.08 years. Commitments for Future Equity Awards In connection with the Company’s acquisitions of businesses as discussed in Note 3 “Acquisitions,” EPAM enters into agreements that contractually commit it to granting equity awards at future dates. The agreements are unique to each acquisition and terms vary to specify the number of future awards to be issued or a monetary value that will be settled with equity awards valued at future stock prices. As of March 31, 2022, the Company has commitments to grant up to $43.1 million of equity awards with the number of awards to be determined based on future stock prices. There is a service-based vesting requirement after the grant date associated with these awards and certain of these awards contain performance criteria that will determine the amount of future awards to be issued. These awards are considered granted for accounting purposes. In determining the expense, the Company adjusts the expected settlement based on the probability of achievement of such performance criteria. Related to these awards, the Company recorded $1.1 million and $1.2 million of stock-based compensation expense in the condensed consolidated statements of income for the quarters ended March 31, 2022 and 2021, respectively. As of March 31, 2022, the Company has commitments to grant 7 thousand RSUs in the future as the grantee has not yet been determined. In addition, as of March 31, 2022, the Company has issued 7 thousand performance-based equity-classified RSUs which are not considered granted for accounting purposes as the future vesting conditions have not yet been determined. On April 15, 2022, the Company granted stock-based compensation awards to employees including 22 thousand stock options, 198 thousand equity-classified RSUs and 7 thousand liability-classified cash-settled RSUs, vesting over 4 years from the grant date.

INCOME TAXES

INCOME TAXES	3 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES In determining its interim provision for income taxes, the Company historically has used an estimated annual effective tax rate, which is based on expected annual profit before tax, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter. During the first quarter of 2022, the Company recorded its interim tax provision using the discrete method rather than using an estimated annual effective tax rate. The discrete method treats the year-to-date period as if it was the annual period and determines the income tax expense or benefit on that basis. The discrete method is applied when the application of the estimated annual effective tax rate is impractical because it is not possible to reliably estimate the annual effective tax rate. In subsequent quarters, the Company will continue to evaluate the practicality of utilizing the annual effective tax rate method. The Company’s worldwide effective tax rates for the three months ended March 31, 2022 and 2021 were 15.6% and 5.1%, respectively. The Company’s effective tax rates benefited from excess tax benefits recorded upon vesting or exercise of stock-based awards of $13.1 million and $21.5 million during the three months ended March 31, 2022 and 2021, respectively.

EARNINGS PER SHARE

EARNINGS PER SHARE	3 Months Ended

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE Basic earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. For purposes of computing basic earnings per share, any nonvested shares of restricted stock that have been issued by the Company and are contingently returnable to the Company are excluded from the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, unvested restricted stock, unvested equity-settled RSUs and the stock to be issued under the Company’s ESPP. The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. The following table sets forth the computation of basic and diluted earnings per share of common stock as follows: Three Months Ended 2022 2021 Numerator for basic and diluted earnings per share: Net income $ 89,719 $ 109,046 Numerator for basic and diluted earnings per share $ 89,719 $ 109,046 Denominator: Weighted average common shares for basic earnings per share 56,915 56,170 Net effect of dilutive stock options, restricted stock units, restricted stock awards and stock issuable under the ESPP 2,026 2,608 Weighted average common shares for diluted earnings per share 58,941 58,778 Net income per share: Basic $ 1.58 $ 1.94 Diluted $ 1.52 $ 1.86 The number of shares underlying equity-based awards that were excluded from the calculation of diluted earnings per share as their effect would be anti-dilutive was 137 thousand and 16 thousand during the three months ended March 31, 2022 and 2021, respectively.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES	3 Months Ended

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Indemnification Obligations — In the normal course of business, the Company is a party to a variety of agreements under which it may be obligated to indemnify the other party for certain matters. These obligations typically arise in contracts where the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations or covenants for certain matters, infringement of third party intellectual property rights, data privacy violations, and certain tortious conduct in the course of providing services. The duration of these indemnifications varies, and in certain cases, is indefinite. The Company is unable to reasonably estimate the maximum potential amount of future payments under these or similar agreements due to the unique facts and circumstances of each agreement and the fact that certain indemnifications provide for no limitation to the maximum potential future payments under the indemnification. Management is not aware of any such matters that would have a material effect on the condensed consolidated financial statements of the Company. Litigation — From time to time, the Company is involved in litigation, claims or other contingencies arising in the ordinary course of business. The Company accrues a liability when a loss is considered probable and the amount can be reasonably estimated. When a material loss contingency is reasonably possible but not probable, the Company does not record a liability, but instead discloses the nature and the amount of the claim, and an estimate of the loss or range of loss, if such an estimate can be made. Legal fees are expensed as incurred. In the opinion of management, the outcome of any existing claims and legal or regulatory proceedings, if decided adversely, is not expected to have a material effect on the Company’s business, financial condition, results of operations or cash flows.

SEGMENT INFORMATION

SEGMENT INFORMATION	3 Months Ended
	Mar. 31, 2022
Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company determines its business segments and reports segment information in accordance with how the Company’s chief operating decision maker (“CODM”) organizes the segments to evaluate performance, allocate resources and make business decisions. Segment results are based on the segment’s revenues and operating profit, where segment operating profit is defined as income from operations before unallocated costs. Expenses included in segment operating profit consist principally of direct selling and delivery costs as well as an allocation of certain shared services expenses. Certain corporate expenses are not allocated to specific segments as these expenses are not controllable at the segment level. Such expenses include certain types of professional fees, non-corporate taxes, compensation to non-employee directors and certain other general and administrative expenses, including compensation of specific groups of non-production employees. In addition, the Company does not allocate amortization of intangible assets acquired through business combinations, goodwill and other asset impairment charges, stock-based compensation expenses, acquisition-related costs and certain other one-time charges. These unallocated amounts are combined with total segment operating profit to arrive at consolidated income from operations as reported below in the reconciliation of segment operating profit to consolidated income before provision for income taxes. Additionally, management has determined that it is not practical to allocate identifiable assets by segment since such assets are used interchangeably among the segments. The Company manages its business primarily based on the managerial responsibility for its client base and market. As managerial responsibility for a particular customer relationship generally correlates with the customer’s geographic location, there is a high degree of similarity between customer locations and the geographic boundaries of the Company’s reportable segments. In some cases, managerial responsibility for a particular customer is assigned to a management team in another region and is usually based on the strength of the relationship between customer executives and particular members of EPAM’s senior management team. In such cases, the customer’s activity would be reported through the management team’s reportable segment. See Note 2 “Impact of the Invasion of Ukraine” for more information regarding the Company’s decisions to no longer serve customers in Russia and the subsequent decision to exit its operations in Russia. Revenues from external customers and operating profit/(loss), before unallocated expenses, by reportable segment for the three months ended March 31, 2022 and 2021, were as follows: Three Months Ended 2022 2021 Segment revenues: North America $ 687,711 $ 474,853 Europe 451,970 276,704 Russia 31,933 29,218 Total segment revenues $ 1,171,614 $ 780,775 Segment operating profit/(loss): North America $ 126,734 $ 94,103 Europe 56,711 51,073 Russia (19,484) 979 Total segment operating profit $ 163,961 $ 146,155 Intersegment transactions were excluded from the above on the basis that they are neither included in the measure of a segment’s profit and loss results, nor considered by the CODM during the review of segment results. There were no customers that accounted for more than 10% of total segment revenues during the three months ended March 31, 2022 and 2021. Reconciliation of segment operating profit to consolidated income before provision for income taxes is presented below: Three Months Ended 2022 2021 Total segment operating profit: $ 163,961 $ 146,155 Unallocated amounts: Stock-based compensation expense (7,112) (24,553) Amortization of intangibles assets (5,244) (3,140) Other acquisition-related expenses (579) (1,933) Other unallocated expenses (21,784) (9,278) Income from operations 129,242 107,251 Interest and other (loss)/income, net (165) 5,374 Foreign exchange (loss)/gain (22,785) 2,299 Income before provision for income taxes $ 106,292 $ 114,924 Geographic Area Information Long-lived assets presented in the table below include property and equipment, net of accumulated depreciation and amortization, and management has determined that it is not practical to allocate these assets by segment since such assets are used interchangeably among the segments.

BUSINESS AND SUMMARY OF SIGNI_2

BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2022
Accounting Policies [Abstract]
Nature of Operations	EPAM Systems, Inc. (the “Company” or “EPAM”) is a leading digital transformation services and product engineering company, providing digital platform engineering and software development services to customers located around the world, primarily in North America, Europe, and Asia. The Company’s industry expertise includes financial services, travel and consumer, software and hi-tech, business information and media, life sciences and healthcare, as well as several other industries. The Company is incorporated in Delaware with headquarters in Newtown, Pennsylvania.
Basis of Presentation	Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of EPAM have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP” or “U.S. GAAP”) and Article 10 of Regulation S-X under the Securities Exchange Act of 1934, as amended. The unaudited condensed consolidated financial statements include the financial statements of EPAM Systems, Inc. and its subsidiaries with all intercompany balances and transactions eliminated.
Use of Estimates	The preparation of these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates, and such differences may be material to the unaudited condensed consolidated financial statements. Operating results for the interim periods are not necessarily indicative of results that may be expected to occur for the entire year. In management’s opinion, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position as of March 31, 2022 and the results of its operations and its cash flows for the periods presented.
Concentration of Credit And Interest Rate Risk	Concentration of Credit — Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents, short-term investments and trade receivables. The Company maintains cash, cash equivalents and short-term investments with financial institutions. The Company believes its credit policies reflect normal industry terms and business risk and there is no expectation of non-performance by the counterparties. Interest rate risk — The Company’s exposure to market risk is influenced by the changes in interest rates received on cash and cash equivalent deposits and short-term investments and paid on any outstanding balance on the Company’s borrowings, mainly under the 2021 Credit Agreement, which is subject to a variety of rates depending on the type and timing of funds borrowed (See Note 8 “Debt”). The Company does not believe it is exposed to material direct risks associated with changes in interest rates related to these deposits and borrowings.
Foreign currency risk	Foreign currency risk — The Company’s global operations are conducted predominantly in U.S. dollars. Other than U.S. dollars, the Company generates revenues in various currencies, principally, euros, British pounds, Russian rubles, Swiss francs, and Canadian dollars and incurs expenditures principally in Russian rubles, Polish zlotys, euros, Swiss francs, Hungarian forints, British pounds, Indian rupees, Chinese yuan renminbi and Mexican pesos.
Adoption of New Accounting Standards and Pending Accounting Standards	Adoption of New Accounting Standards There were no recently adopted accounting standards which had a material impact on the Company’s consolidated financial position, results of operations, changes in stockholders’ equity and cash flows. Pending Accounting Standards From time to time, new accounting pronouncements are issued by the FASB or other standards-setting bodies that the Company will adopt according to the various timetables the FASB specifies. The Company believes the impact of recently issued standards that are not yet effective will not have a material impact on its consolidated financial position, results of operations and cash flows upon adoption.
Fair Value of Financial Instruments	The foreign exchange derivatives are valued using pricing models and discounted cash flow methodologies based on observable foreign exchange data at the measurement date. See Note 6 “Derivative Financial Instruments” in the condensed consolidated interim financial statements for additional information regarding derivative financial instruments. As part of the acquisition of Emakina, the Company acquired rights to purchase certain noncontrolling interests in consolidated subsidiaries of Emakina in exchange for future cash payments determined by the future profitability of certain subsidiaries. The Company determines the fair value of these rights by (i) estimating the fair value of the noncontrolling interests in consolidated subsidiaries by applying an EBITDA multiple adjusted for a lack of control and marketability, less (ii) the fair value of expected future payments to settle the related contractual obligations. The Company purchased the majority of the noncontrolling interest in consolidated subsidiaries during the first quarter of 2022. The Company determines the fair value of the contingent consideration liabilities using Monte Carlo simulations or probability-weighted expected return methods. The fair value of the contingent consideration for the PolSource acquisition attributable to future revenues and earnings was measured utilizing a Monte Carlo simulation, based on future revenue and earnings projections of the business, revenue volatility and asset volatility of comparable companies, and a discount rate. The discount rate used to determine the fair value of this contingent consideration was 0.4% as of the acquisition date. The fair value of the contingent consideration for the PolSource acquisition attributable to future operating metrics was measured using a probability-weighted expected return method, based on the expected future payments using the earnout formula and performance targets specified in the purchase agreement and adjusting those estimates to reflect the probability of their achievement. The weighted-average estimated future payments were then discounted to present value using a rate based on EPAM’s cost of debt. The discount rate used to determine the fair value of this contingent consideration was 0.4% as of the acquisition date.
Non-Marketable Securities Without Readily Determinable Fair Values	Non-Marketable Securities Without Readily Determinable Fair ValuesThe Company holds investments in equity securities that do not have readily determinable fair values. These investments are recorded at cost and are remeasured to fair value based on certain observable price changes or impairment events as they occur.
Income Taxes	In subsequent quarters, the Company will continue to evaluate the practicality of utilizing the annual effective tax rate method.
