Pay Versus Performance

We structure our compensation using a mix of short-term compensation, in the form of base salaries and annual cash incentive payments, and long-term compensation, in the form of equity-based awards, to meet our NEO compensation objectives of:

• Attracting, motivating, developing, and retaining quality executives who will increase long-term stockholder value.

• Providing total compensation that is commensurate with position and experience, primarily through annual and long-term incentives aligned with the long-term interests of our stockholders.

• Rewarding exceptional performance and long-term commitment to EPAM.

Our Compensation Discussion and Analysis that begins on page 25 of this Proxy Statement provides more information on our approach and methodology for making executive compensation decisions. As noted in the Compensation Discussion and Analysis, particularly in the tables starting on page 35, our compensation decisions are made using the value of equity-based awards measured as of the date the equity award was granted, which differs from the values in the table below which are calculated according to prescribed SEC rules. Particularly, the amounts listed in the tables and graphs below labeled as “Compensation Actually Paid” does not represent the value of cash and equity awards that we paid to our NEOs during any year, but rather is an amount calculated under SEC rules and includes, among other things, adjustments to values of unvested and vested equity awards based on year-end stock prices and various accounting valuation assumptions.

(1) Columns (b) and (d) respectively list compensation amounts reported in the “Total” column of the Summary Compensation Table (SCT) for our CEO, Arkadiy Dobkin, and an average of the amounts from the “Total” column in the Summary Compensation Table for our four NEOs that are not our CEO, namely Jason Peterson, Balazs Fejes, Viktar Dvorkin, and Larry Solomon, for the respective years shown.

(2) Column (c) reflects the “Compensation Actually Paid” to our CEO in each of 2022, 2021 and 2020 calculated as set forth in the table below and in accordance with SEC rules. No dividends or other earnings were paid on stock or option awards in any of the covered fiscal years and no equity awards were cancelled due to a failure to meet vesting conditions. The dollar amounts reflected in column (c) of the table above do not reflect the actual amount of compensation earned by or paid to our CEO during any of the applicable years. For information regarding the decisions made by our Compensation Committee about our CEO’s compensation for each fiscal year, please see the Compensation Discussion and Analysis section of this Proxy Statement and the proxy statements for each of the fiscal years covered in the table above.

Stock option grant date fair values included in SCT Total Compensation are estimated using the Black-Scholes option valuation model as of grant date. For the purposes of calculating Compensation Actually Paid, we estimated the stock option fair values using the Black-Scholes option valuation model as of each applicable measurement date using the stock price as of the measurement date and updated assumptions (i.e., expected term, expected volatility, expected dividends, risk-free interest rate) as of the measurement date. Restricted stock unit grant date fair values are calculated as set forth in the footnotes to the Summary Compensation Table. For the purposes of calculating Compensation Actually Paid, adjustments were made using the stock price as of the last trading day of each applicable year and as of each applicable measurement date.

(3) Column (e) reflects the average Compensation Actually Paid to our four NEOs that are not our CEO in each of 2022, 2021 and 2020, calculated as set forth in the table below and in accordance with SEC rules. No dividends or other earnings were paid on stock or option awards in any of the covered fiscal years and no equity awards were cancelled due to a failure to meet vesting conditions. The dollar amounts reflected in column (e) of the table above do not reflect the actual amount of compensation earned by or paid to our NEOs during any of the applicable years. For information regarding the decisions made by our Compensation Committee about our NEO’s compensation for each fiscal year, please see the Compensation Discussion and Analysis section of this Proxy Statement and the proxy statements for each of the fiscal years covered in the table above.
