FIS Use of Non-GAAP Financial Information Generally Accepted Accounting Principles (GAAP) is the term used to refer to the standard framework of guidelines for financial accounting in the United States. GAAP includes the standards, conventions, and rules accountants follow in recording and summarizing transactions and in the preparation of financial statements. In addition to reporting financial results in accordance with GAAP, we have provided certain non-GAAP financial measures. These non-GAAP measures include constant currency revenue, adjusted revenue growth, adjusted EBITDA, adjusted EBITDA margin, adjusted net earnings, adjusted EPS, and free cash flow. These non-GAAP measures may be used in this release and/or in the attached supplemental financial information. We believe these non-GAAP measures help investors better understand the underlying fundamentals of our business. As further described below, the non-GAAP revenue and earnings measures presented eliminate items management believes are not indicative of FIS’ operating performance. The constant currency revenue and adjusted revenue growth measures adjust for the effects of exchange rate fluctuations and exclude discontinued operations, while adjusted revenue growth also excludes revenue from Corporate and Other, giving investors further insight into our performance. Finally, free cash flow provides further information about the ability of our business to generate cash. For these reasons, management also uses these non-GAAP measures in its assessment and management of FIS’ performance. Constant currency revenue represents reported segment revenue excluding the impact of fluctuations in foreign currency exchange rates in the current period. Adjusted revenue growth reflects the percentage change in constant currency revenue for the current period as compared to the prior period. When referring to adjusted revenue growth, revenue from our Corporate and Other segment is excluded. Adjusted EBITDA reflects net earnings (loss) before interest, other income (expense), taxes, equity method investment earnings (loss), and depreciation and amortization, and excludes certain costs and other transactions that management deems non-operational in nature, or that otherwise improve the comparability of operating results across reporting periods by their exclusion. This measure is reported to the chief operating decision maker for purposes of making decisions about allocating resources to the segments and assessing their performance. For this reason, adjusted EBITDA, as it relates to our segments, is presented in conformity with Accounting Standards Codification 280, Segment Reporting, and is excluded from the definition of non-GAAP financial measures under the Securities and Exchange Commission's Regulation G and Item 10(e) of Regulation S-K. Adjusted EBITDA margin reflects adjusted EBITDA, as defined above, divided by revenue. Adjusted net earnings excludes the impact of certain costs and other transactions which management deems non-operational in nature or that otherwise improve the comparability of operating results across reporting periods by their exclusion. These include, among others, the impact of acquisition-related purchase accounting amortization which is recurring. For purposes of calculating Adjusted net earnings, our equity method investment earnings (loss) (EMI) from Worldpay is also adjusted to exclude certain costs and other transactions in a similar manner. Adjusted EPS reflects adjusted net earnings, as defined above, divided by weighted average diluted shares outstanding. Free cash flow reflects net cash provided by operating activities, adjusted for the net change in settlement assets and obligations and excluding certain transactions that are closely associated with non-operating activities or are otherwise non-operational in nature and not indicative of future operating cash flows, less capital expenditures. Free cash flow does not represent our residual cash flow available for discretionary expenditures since we have mandatory debt service requirements and other non-discretionary expenditures that are not deducted from the measure. Free cash flow as presented in this earnings release excludes cash flow from discontinued operations, which our management will not be able to freely access following the Worldpay separation. Any non-GAAP measures should be considered in context with the GAAP financial presentation and should not be considered in isolation or as a substitute for GAAP measures. Further, FIS’ non-GAAP measures may be calculated differently from similarly titled measures of other companies. Reconciliations of these non-GAAP measures to related GAAP measures, including footnotes describing the adjustments, are provided in the attached schedules and in the Investor Relations section of the FIS website, www.fisglobal.com.

Notes to Unaudited – Supplemental GAAP to Non-GAAP Reconciliations This item represents purchase price amortization expense on all intangible assets acquired through various Company acquisitions, including customer relationships, contract value, technology assets, trademarks and trade names. This item also includes $53 million for the year ended December 31, 2022, of incremental amortization expense associated with shortened estimated useful lives and accelerated amortization methods for certain acquired software driven by the Company's platform modernization. The Company has excluded the impact of purchase price amortization expense as such amounts can be significantly impacted by the timing and/or size of acquisitions. Although the Company excludes these amounts from its non-GAAP expenses, the Company believes that it is important for investors to understand that such intangible assets contribute to revenue generation. Amortization of assets that relate to past acquisitions will recur in future periods until such assets have been fully amortized. Any future acquisitions may result in the amortization of future assets. This item represents costs comprised of the following table: (a) For purposes of calculating Adjusted net earnings, this item includes incremental amortization expense associated with shortened estimated useful lives and accelerated amortization methods for certain software and deferred contract cost assets driven by the Company's platform modernization. The incremental amortization expenses are included in the Depreciation and amortization, excluding purchase accounting amortization line item within the Adjusted EBITDA reconciliation. For the year ended December 31, 2023, this item includes impairments primarily related to the termination of certain internally developed software projects. For the year ended December 31, 2023, this item also includes a $6.8 billion impairment of goodwill related to the Merchant Solutions reporting unit due to its estimated fair value being less than its carrying value based on the price, including estimated selling price adjustments and fair value of contingent consideration, at which the Company has agreed to sell a majority stake in the unit, recorded in discontinued operations. For the year ended December 31, 2022, this item primarily represents a $17.6 billion impairment of goodwill related to the Merchant Solutions reporting unit due its estimated fair value being less than its carrying value based on slowing growth projections for the business, a sustained decline in our share price and the effects of changing market dynamics affecting our SMB portfolio. For the year ended December 31, 2022, this item also includes impairments related to real estate assets, a non-strategic business and certain software assets. This item represents costs that were previously incurred in support of the Worldpay Merchant Solutions business but are not directly attributable to it and thus were not recorded in discontinued operations. The Company expects that it will be reimbursed for these expenses as part of Transition Services Agreements with the purchaser or eliminate them post separation; therefore, the expenses have been adjusted out of continuing operations and added to discontinued operations.
