P 0 8#9Executive Compensation Highlights 2022 Short-term Incentive Plan Outcomes Applied downward discretion to align the NEOs' annual incentive targets with consensus values. Our use of negative discretion for the NEOs' bonuses was out of the ordinary and we do not intend to exercise discretion on an ongoing basis. 2023 Compensation Program Consists of 25% RSUS and 75% PSUs. Returned to three-year PSUs with three-year targets. Incentivize top- and bottom-line growth with equally weighted EBITDA and Revenue metrics. Continued inclusion of an rTSR modifier that can adjust the PSU vesting factors upward or downward by 25%. PSUs also include a TSR governor that caps the vesting factor at target unless the absolute TSR of the Company is positive, to ensure that executives do not receive meaningful payouts unless we deliver positive stock price growth over the long term to stockholders.

BOOKING HOLDINGS A B. P 0 16#17Appendix: Non-GAAP Financial Information BOOKING HOLDINGS B. P Q R K O 17#18Appendix: Unaudited Reconciliation of GAAP to Non-GAAP Financial Information Non-GAAP Financial Measures: While the Company reports financial results in accordance with accounting principles generally accepted in the United States, this presentation includes Adjusted EBITDA, a non-GAAP measure which is not presented in accordance with GAAP or a substitute for GAAP measures. The Company considers Adjusted EBITDA as an important supplemental measure of its performance. Adjusted EBITDA is often used to assess the Company's performance because it allows comparison of operating performance on a consistent basis across periods by removing the effects of various items. Adjusted EBITDA has various limitations as an analytical tool, and the recipient should not consider it in isolation, or as a substitute for analysis of the Company's results as reported under GAAP. Further, because not all companies use identical calculations, the presentation herein of non-GAAP measures may not be comparable to other similarly titled measures reported by other companies.
