Adjusted EBITDA and Net Adjusted EBITDA Margin Adjusted EBITDA is a non-GAAPfinancial measure defined as net income plus income tax expense (benefit), net interest income (expense), net other income (expense), depreciation, amortization and stock-based compensation, as well as significant transaction-related expenses. Adjusted EBITDA should be considered in addition to, rather than as a substitute for, net income. Net Adjusted EBITDA Margin is a non-GAAPfinancial measure defined as Adjusted EBITDA divided by Revenue Net of Interchange. For purposes of calculations under our 2024 short-term incentive program awards and our 2024 PSU awards, we further adjusted Adjusted EBITDA (including for purposes of calculating Net Adjusted EBITDA Margin) to be based on our 2024 budgeted foreign exchange rate rather than our actual foreign exchange rates. 2025 PROXY STATEMENT A-1
