The factors that could cause the company’s actual results to differ materially include, among others, the following: the company's ability to compete effectively against new and existing competitors and to continue to introduce competitive new products and services on a timely, cost-effective basis; changes in customer demand for the company's products and services; the ability of the company's technology to keep pace with a rapidly evolving marketplace; the success of the company's merchant alliances, some of which are not controlled by the company; the impact of a security breach or operational failure on the company's business, including disruptions caused by other participants in the global financial system; losses due to chargebacks, refunds or returns as a result of fraud or the failure of the company's vendors and merchants to satisfy their obligations; changes in local, regional, national and international economic or political conditions, including those resulting from heightened inflation, rising interest rates, taxes, trade policies and tariffs, a recession, bank failures, or intensified international hostilities, and the impact they may have on the company and its employees, clients, vendors, supply chain, operations and sales; the effect of proposed and enacted legislative and regulatory actions affecting the company or the financial services industry as a whole; the company's ability to comply with government regulations and applicable card association and network rules; the protection and validity of intellectual property rights; the outcome of pending and future litigation and governmental proceedings; the company's ability to successfully identify, complete and integrate acquisitions, and to realize the anticipated benefits associated with the same; the impact of the company’s growth strategies; the company’s ability to attract and retain key personnel; adverse impacts from currency exchange rates or currency controls; changes in corporate tax and interest rates; and other factors included in “Risk Factors” in the company's Annual Report on Form 10-K for the year ended December 31, 2024, and in other documents that the company files with the Securities and Exchange Commission, which are available at http://www.sec.gov.

• 11. Non-GAAP Financial Measures Use of Non-GAAP Financial Measures This presentation includes the following unaudited non-GAAP financial measures: “adjusted revenue,” “adjusted revenue growth,” “organic revenue,” “organic revenue growth,” “adjusted operating income,” “adjusted operating margin,” “adjusted operating margin expansion,” “adjusted net income,” “adjusted earnings per share,” “adjusted earnings per share growth,” and “free cash flow.” Management believes that adjustments for certain non-cash or other items and the exclusion of certain pass-through revenue and expenses should enhance shareholders’ ability to evaluate the company’s performance, as such measures provide additional insights into the factors and trends affecting its business. Additional information about these measures and reconciliations to the nearest GAAP financial measures are provided in this appendix. Forward-Looking Non-GAAP Financial Measures Reconciliations of unaudited non-GAAP financial measures to the most comparable GAAP measures are included in this appendix, except for forward-looking measures where a reconciliation to the corresponding GAAP measures is not available due to the variability, complexity and limited visibility of these items that are excluded from the non-GAAP outlook measures. The company's forward-looking non-GAAP financial measures for 2025, including organic revenue growth, adjusted earnings per share, adjusted earnings per share growth, adjusted operating margin expansion, and free cash flow, are designed to enhance shareholders’ ability to evaluate the company's performance by excluding certain items to focus on factors and trends affecting its business. The company’s organic revenue growth outlook excludes the impact of foreign currency fluctuations, acquisitions, dispositions and the impact of the company’s postage reimbursements. Estimates of these impacts and adjustments on a forward-looking basis are presented on the slide titled “2025 Performance Outlook - Organic Revenue Growth” and are subject to variability. The company’s adjusted earnings per share and adjusted operating margin outlooks exclude certain non-cash or other items such as non-cash intangible asset amortization expense associated with acquisitions; non-cash impairment charges; merger and integration costs; severance costs; gains or losses from the sale of businesses, certain assets and investments; and certain discrete tax benefits and expenses. The company's adjusted operating margin outlook also excludes the impact of the company’s postage reimbursements. The company’s free cash flow outlook includes, but is not limited to, capital expenditures, distributions paid to noncontrolling interests, and distributions from unconsolidated affiliates and excludes severance, merger and integration payments. The company estimates that amortization expense in 2025 with respect to acquired intangible assets will decrease approximately 5% compared to the amount incurred in 2024. Other adjustments to the company’s financial measures that were incurred in 2024 and for the three and six months ended June 30, 2025 are presented on the subsequent pages of this presentation; however, they are not necessarily indicative of adjustments that may be incurred throughout the remainder of 2025 or beyond. Estimates of these impacts and adjustments on a forward-looking basis are not available due to the variability, complexity and limited visibility of these items.

• 20. Adjusted Net Income and Adjusted EPS (cont.) 1 Represents acquisition and related integration costs incurred in connection with acquisitions. Merger and integration costs associated with integration activities include �3 million and �5 million of third-party professional service fees in the second quarter and first six months of 2025, respectively, as well as �11 million related to a legal settlement in the first six months of 2025. 2 Represents amortization of intangible assets acquired through acquisition, including customer relationships, software/technology and trade names. This adjustment does not exclude the amortization of other intangible assets such as contract costs (sales commissions and deferred conversion costs), capitalized and purchased software, financing costs and debt discounts. 3 Represents the company’s share of amortization of acquisition-related intangible assets at its unconsolidated affiliates, as well as the minority interest share of amortization of acquisitionrelated intangible assets at its subsidiaries in which the company holds a controlling financial interest. 4 The tax impact of adjustments is calculated using a tax rate of 19.5%, which approximates the company’s anticipated annual effective tax rate. 5 Represents incremental compensation expense associated with the transition of the company’s Chief Executive Officer (“CEO”), comprised of �40 million of former CEO non-cash sharebased compensation and related employer payroll taxes, and a �12 million cash replacement award to the company’s newly appointed CEO. 6 The Argentine government announced economic policy changes, including the removal of certain currency controls, resulting in a significant devaluation of the Argentine Peso on April 14, 2025. This adjustment represents the corresponding one-day foreign currency exchange loss from the remeasurement of the company’s Argentina subsidiary’s monetary assets and liabilities in Argentina’s highly inflationary economy.

The company adjusts its non-GAAP results to exclude amortization of acquisition-related intangible assets as such amounts are inconsistent in amount and frequency and are significantly impacted by the timing and/or size of acquisitions. Management believes that the adjustment of acquisition-related intangible asset amortization supplements the GAAP information with a measure that can be used to assess the comparability of operating performance. Although the company excludes amortization from acquisition-related intangible assets from its non-GAAP expenses, management believes that it is important for investors to understand that such intangible assets were recorded as part of purchase accounting and contribute to revenue generation. Amortization of intangible assets that relate to past acquisitions will recur in future periods until such intangible assets have been fully amortized. Any future acquisitions may result in the amortization of additional intangible assets.
