Non-GAAP Financial Measures

The Unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ('GAAP') and include all normal and recurring adjustments that management of the Company considers necessary for a fair presentation of its financial position and operating results.

To supplement the Unaudited Consolidated Financial Statements, the Company uses the following non-GAAP financial measures: Adjusted Net income (loss), Adjusted EPS, Adjusted EBITDA and Free cash flow (Net cash provided by (used in) operating activities less capital expenditures). The presentation of non-GAAP financial information should not be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

The Company uses non-GAAP financial measures for financial and operational decision-making and as a basis to evaluate performance and set targets for employee compensation programs. The Company believes that these nonGAAP financial measures are useful for analysts and investors to evaluate the Company's ongoing operating performance because they facilitate comparison of the Company's results for the current period and projected nextperiod results to those of prior periods and to those of its competitors (though other companies may calculate similar non-GAAP financial measures differently from those calculated by the Company). These non-GAAP financial measures, in particular Adjusted Net income (loss), Adjusted EBITDA and Free cash flow, are not intended to represent funds available for Booking Holdings' discretionary use and are not intended to represent or to be used as a substitute for Operating income (loss), Net income (loss) or Net cash provided by (used in) operating activities as

measured under GAAP. The items excluded from these non-GAAP measures, but included in the calculation of their closest GAAP equivalent, are significant components of the Company's consolidated statements of operations and cash flows and must be considered in performing a comprehensive assessment of overall financial performance.

Adjusted Net income (loss) is Net income (loss) with the following adjustments: excludes accruals related to the Netherlands pension fund matter (recorded during the year ended December 31, 2023),

excludes accruals related to a draft decision by the Spanish competition authority, excludes accruals related to settlements of certain indirect tax matters, excludes the termination fee related to an acquisition agreement, excludes gains and losses on equity securities with readily determinable fair values, excludes the impact, if any, of significant gains and losses on the sale of and impairment and credit losses on investments in available-for-sale debt securities and significant gains and losses on the sale of and impairment and other valuation adjustments on investments in equity securities without readily determinable fair values, excludes foreign currency transaction gains and losses on the remeasurement of Euro-denominated debt and accrued interest that are not designated as hedging instruments for accounting purposes and debtrelated foreign currency derivative instruments used as economic hedges, excludes amortization expense of intangible assets, excludes interest received on tax payments refunded pursuant to settlement with authorities, excludes the impact of net unrecognized tax benefits related to certain income tax matters, and the income tax impact of the non-GAAP adjustments mentioned above and changes in tax estimates, as applicable.

In the event the Company reports a GAAP Net income but an Adjusted Net loss, dilutive shares that are included in the GAAP weighted-average number of diluted common shares outstanding are excluded from the non-GAAP weighted-average number of diluted common shares outstanding. In the event the Company reports a GAAP Net loss but an Adjusted Net income, anti-dilutive shares that are excluded from the GAAP weighted-average number of diluted common shares outstanding are included in the non-GAAP weighted-average number of diluted common shares outstanding.

In addition to the adjustments listed above regarding Adjusted Net income (loss), Adjusted EBITDA excludes depreciation expense, interest expense, and to the extent not included in the adjustments listed above, interest and dividend income, and income tax expense (benefit).

We evaluate certain operating and financial measures on both an as-reported and constant-currency basis. We calculate constant currency based on the predominant transactional currency in each country, converting our current-year period results in currencies other than U.S. Dollars using the corresponding prior-year period monthly average exchange rates.

The attached financial and statistical supplement includes reconciliations of our financial results under GAAP to non-GAAP financial information for the three months ended March 31, 2024 and 2023. We are not able to provide a reconciliation between forward-looking Adjusted EBITDA and GAAP Net income (loss) because we cannot predict certain components of such reconciliation without unreasonable effort as they arise from events in future periods.
