APPENDIX: About Non-GAAP Financial Measures and Performance Metrics

© 2025 Cognizant 14 Non-GAAP Financial Measures To supplement our financial results presented in accordance with GAAP, this earnings supplement includes references to the following measures defined by the Securities and Exchange Commission as non-GAAP financial measures: Adjusted Operating Margin, Adjusted Diluted EPS, free cash flow, constant currency revenue growth and Adjusted effective tax rate. These non- GAAP financial measures are not based on any comprehensive set of accounting rules or principles and should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and may be different from non-GAAP financial measures used by other companies. In addition, these non-GAAP financial measures should be read in conjunction with our financial statements prepared in accordance with GAAP. The reconciliations of our non-GAAP financial measures to the corresponding GAAP measures should be carefully evaluated. Our non-GAAP financial measures Adjusted Operating Margin and Adjusted Income from Operations exclude unusual items, such as the gain on sale of property and equipment and NextGen charges. Our non-GAAP financial measure Adjusted Diluted EPS excludes unusual items, such as the gain on sale of property and equipment and NextGen charges, and net non-operating foreign currency exchange gains or losses and the tax impact of all the applicable adjustments. The income tax impact of each item excluded from Adjusted Diluted EPS is calculated by applying the statutory rate and local tax regulations in the jurisdiction in which the item was incurred. Free cash flow is defined as cash flows from operating activities plus proceeds from sale of property and equipment, net of purchases of property and equipment. Constant currency revenue growth is defined as revenues for a given period restated at the comparative period’s foreign currency exchange rates measured against the comparative period's reported revenues. Adjusted effective tax rate reflects a tax rate commensurate with our non-GAAP Adjusted EPS. Management believes providing investors with an operating view consistent with how we manage the Company provides enhanced transparency into our operating results. For our internal management reporting and budgeting purposes, we use various GAAP and non-GAAP financial measures for financial and operational decision-making, to evaluate period-to-period comparisons, to determine portions of the compensation for our executive officers and for making comparisons of our operating results to those of our competitors. Accordingly, we believe that the presentation of our non-GAAP measures, which exclude certain costs, when read in conjunction with our reported GAAP results, can provide useful supplemental information to our management and investors regarding financial and business trends relating to our financial condition and results of operations. A limitation of using non-GAAP financial measures versus financial measures calculated in accordance with GAAP is that non-GAAP financial measures do not reflect all of the amounts associated with our operating results as determined in accordance with GAAP and may exclude costs that are recurring such as our net non-operating foreign currency exchange gains or losses. In addition, other companies may calculate non-GAAP financial measures differently than us, thereby limiting the usefulness of these non-GAAP financial measures as a comparative tool. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from our non-GAAP financial measures to allow investors to evaluate such non-GAAP financial measures. Performance Metrics Bookings are defined as total contract value (or TCV) of new contracts, including new contract sales as well as renewals and expansions of existing contracts. Bookings can vary significantly quarter to quarter depending in part on the timing of the signing of a small number of large contracts. Our book-to-bill ratio is defined as bookings for the trailing twelve months divided by revenue for the same period. Measuring bookings involves the use of estimates and judgments and there are no independent standards or requirements governing the calculation of bookings. The extent and timing of conversion of bookings to revenues may be impacted by, among other factors, the types of services and solutions sold, contract duration, the pace of client spending, actual volumes of services delivered as compared to the volumes anticipated at the time of sale, and contract modifications, including terminations, over the lifetime of a contract. The majority of our contracts are terminable by the client on short notice often without penalty, and some without notice. We do not update our bookings for subsequent terminations, reductions or foreign currency exchange rate fluctuations. Information regarding our bookings is not comparable to, nor should it be substituted for, an analysis of our reported revenues. However, management believes that it is a key indicator of potential future revenues and provides a useful indicator of the volume of our business over time.

© 2025 Cognizant 16 Reconciliations of Non-GAAP Financial Measures Notes: (a) During the three months ended March 31, 2025, we realized a gain of $62 million on the sale of an office complex in India, which was reported in "(Gain) on sale of property and equipment" on our unaudited consolidated statement of operations. Our guidance anticipates pre-tax charges of approximately $(0.13) per diluted share for the full year 2025. The tax effect of these charges is expected to be approximately $0.02 per diluted share for the full year 2025. (b) At the end of 2024, we completed our NextGen program, which was aimed at simplifying our operating model, optimizing corporate functions and consolidating and realigning office space to reflect the post-pandemic hybrid work environment. The total costs related to the NextGen program are reported in "Restructuring charges" in our unaudited consolidated statements of operations. (c) Non-operating foreign currency exchange gains and losses, inclusive of gains and losses related to foreign exchange forward contracts not designated as hedging instruments for accounting purposes, are reported in "Foreign currency exchange gains (losses), net" in our unaudited consolidated statements of operations. Non-operating foreign currency exchange gains and losses are subject to high variability and low visibility and therefore cannot be provided on a forward-looking basis without unreasonable efforts. 2024 2025 Three months ended: Mar 31 Jun 30 Sep 30 Dec 31 Mar 31 Non-GAAP income tax benefit (expense) related to: Gain on sale of property and equipment $ — $ — $ — $ — $ (9) NextGen charges 5 8 8 13 — Tax impact of foreign currency exchange gain and losses (1) 1 (3) (1) (3) (d) Presented below are the tax impacts of our non-GAAP adjustments to pre-tax income: The effective tax rate related to non-operating foreign currency exchange gains and losses varies depending on the jurisdictions in which such income and expenses are generated and the statutory rates applicable in those jurisdictions.
