APPENDIX: About Non-GAAP Financial Measures and Performance Metrics

© 2023 Cognizant 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 and constant currency revenue growth. 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 measure Adjusted Operating Margin excludes unusual items. Our non-GAAP financial measure Adjusted Diluted EPS excludes unusual items, such as the effect of recognition in the third quarter of 2022 of an income tax benefit related to a specific uncertain tax position that was previously unrecognized in our prior year consolidated financial statements, 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 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. 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. In the first quarter of 2023, we introduced a new metric, Voluntary Attrition – Tech Services, which includes voluntary separations with the exception of employees in our Intuitive Operations and Automation practice. This new metric replaces our prior attrition disclosure of company-wide voluntary and involuntary attrition.

© 2023 Cognizant Reconciliations of Non-GAAP Financial Measures Notes: (a) In connection with the NextGen program, which was initiated in the second quarter of 2023, we expect to record costs of approximately $400 million with approximately $350 million of such costs anticipated in 2023 and approximately $50 million in 2024. This consists of approximately $200 million of employee severance and other costs primarily related to non-billable and corporate personnel, which we expect to mostly incur in 2023, and approximately $200 million of costs related to the consolidation of office space, with approximately $150 million in 2023 and $50 million in 2024. We expect the personnel-related actions of this program to impact approximately 3,500 employees. The impact to the effective tax rate is expected to be immaterial. The estimates of the charges and expenditures that we expect to incur in connection with the NextGen program, and the timing thereof, are subject to a number of assumptions, including local law requirements in various jurisdictions, and actual amounts may differ materially from estimates. In addition, we may incur other charges or cash expenditures not currently contemplated due to unanticipated events that may occur in connection with the NextGen program. (b) 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. 17 (d) During the three months ended September 30, 2022, we recognized an income tax benefit previously unrecognized in our consolidated financial statements related to a specific uncertain tax position of $36 million. The recognition of the benefit in the third quarter of 2022 was based on management’s reassessment regarding whether this unrecognized tax benefit met the more-likely-than-not threshold in light of the lapse in the statute of limitations as to a portion of such benefit. 2022 2023 Three months ended: Mar 31 Jun 30 Sep 30 Dec 31 Mar 31 Tax impact of foreign currency exchange gain and losses (6) (14) (15) (4) 5 (c) Presented below are the tax impacts of our non-GAAP adjustment 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. As such, the income tax effect of non-operating foreign currency exchange gains and losses shown in the above table may not appear proportionate to the net pre-tax foreign currency exchange gains and losses reported in our consolidated statements of operations.
