Booking Holdings Inc. (BKNG) FY 2021 MD&A

Management's Discussion and Analysis of Financial Condition and Results of Operations is based upon our Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). Our significant accounting policies and estimates are more fully described in Note 2 to our Consolidated Financial Statements. Certain of our accounting estimates are particularly important to our financial position and results of operations and require us to make difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. We use our judgment to determine the appropriate assumptions to be used in the determination of certain estimates and we evaluate our estimates on an ongoing basis. Estimates are based on historical experience, terms of existing contracts, our observance of trends in the travel industry, and on various other assumptions that we believe to be reasonable under the circumstances. Our actual results may differ from these estimates under different assumptions or conditions. Matters that involve significant estimates and judgments of management include the following:

Valuation of Goodwill and other Long-lived Assets

The application of the acquisition method of accounting for business combinations requires the use of significant estimates and assumptions to determine the fair value of the assets acquired and liabilities assumed. Our estimates of the fair value are based upon assumptions that we believe are reasonable. When we deem appropriate, we utilize assistance from third-party valuation firms. The consideration transferred is allocated to the assets acquired and liabilities assumed based on their respective fair values at the acquisition date. The excess of the consideration transferred over the net of the amounts allocated to the identifiable assets acquired and liabilities assumed is recognized as goodwill. Goodwill is assigned to reporting units that are expected to benefit from the synergies of the business combination.

44

A substantial portion of our intangible assets and goodwill relates to the acquisitions of OpenTable, KAYAK, and Getaroom. See Note 19 to our Consolidated Financial Statements for further information related to the acquisition of Getaroom in December 2021.

We review long-lived assets whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The assessment of possible impairment is based upon the ability to recover the carrying value of the assets from the estimated undiscounted future net cash flows, before interest and taxes, of the related asset group. As of December 31, 2021, no impairment indicators were identified for our long-lived assets.

We test goodwill for impairment on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. We test goodwill at a reporting unit level and our annual goodwill impairment tests are performed as of September 30. As of September 30, 2021, we performed our annual goodwill impairment test and concluded that there was no impairment of goodwill. No additional impairment indicators were identified as of December 31, 2021.

2020 Interim Goodwill Impairment Test

Due to the significant and negative financial impact of the COVID-19 pandemic (see Note 2 to our Consolidated Financial Statements), we performed an interim period goodwill impairment test at March 31, 2020 and recognized a goodwill impairment charge of $489 million related to the OpenTable and KAYAK reporting unit for the three months ended March 31, 2020, which is not tax-deductible, resulting in an adjusted carrying value of goodwill for OpenTable and KAYAK of $1.5 billion at March 31, 2020. The goodwill impairment was primarily driven by a significant reduction in the forecasted near-term cash flows of OpenTable and KAYAK as well as the significant decline in comparable companies' market values as a result of the COVID-19 pandemic.

The estimated fair value of OpenTable and KAYAK was determined using a combination of standard valuation techniques, including an income approach (discounted cash flows) and a market approach (applying the recent decline in enterprise values of comparable publicly-traded companies to the recently calculated fair value for OpenTable and KAYAK as well as applying comparable company multiples).

The income approach estimates fair value utilizing long-term growth rates and discount rates applied to the cash flow projections. In the cash flow projections, we assumed at the time that OpenTable and KAYAK would experience a significant decline in near-term cash flows with a recovery to 2019 levels of financial performance (including profitability) occurring in 2023. The shape and timing of the recovery was a key assumption in our fair value calculation (both in the income and market approaches).

2020 Annual Goodwill Impairment Test

As of September 30, 2020, we performed our annual goodwill impairment test and recognized a goodwill impairment charge of $573 million for the OpenTable and KAYAK reporting unit for the three months ended September 30, 2020, which is not tax-deductible, resulting in an adjusted carrying value of goodwill for OpenTable and KAYAK of $1.0 billion at September 30, 2020. The goodwill impairment was primarily driven by a significant reduction in the forecasted cash flows of OpenTable and KAYAK, reflecting a longer assumed recovery period to 2019 levels of profitability, mainly due to the continued material adverse impact of the COVID-19 pandemic, including its impact on the flight vertical at KAYAK, and the lowered outlook for monetization opportunities in restaurant reservation services.

The estimated fair value of OpenTable and KAYAK was determined using a combination of standard valuation techniques, including an income approach (discounted cash flows) and a market approach (applying comparable company multiples).

The income approach estimates fair value utilizing long-term growth rates and discount rates applied to the cash flow projections. The income approach, applied as of September 30, 2020, reflected a reduction in the forecasted cash flows of OpenTable and KAYAK and a longer assumed recovery period to 2019 levels of profitability, driven primarily by a lowered outlook for monetization opportunities in restaurant reservation services and slower than previously expected recovery trends for airline travel, which is a key vertical for KAYAK. For the interim goodwill impairment test at March 31, 2020, we expected a recovery to 2019 levels of financial performance occurring in 2023 for OpenTable and KAYAK. Based on our evaluation of all relevant information available as of September 30, 2020 for the annual goodwill impairment test, we expected at the time that OpenTable and KAYAK would not return to the 2019 level of profitability within five years from that date, and that it was uncertain whether the shape of the recovery would ultimately match our expectations. An increase or decrease of one

45

percentage point to the profitability growth rates used in the cash flow projections would have resulted in an increase or decrease of approximately $100 million to the estimated fair value of OpenTable and KAYAK as of September 30, 2020. The discount rate is determined based on the reporting unit’s estimated weighted-average cost of capital and adjusted to reflect the risks inherent in its cash flows, which requires significant judgments. The discount rate used for the annual goodwill impairment test as of September 30, 2020 was higher than the discount rate used for the interim goodwill impairment test as of March 31, 2020. If the discount rate used in the income approach increases or decreases by 0.5%, the impact to the estimated fair value of OpenTable and KAYAK, at September 30, 2020, would have ranged from a decrease of approximately $65 million to an increase of approximately $70 million.

The estimation of fair values of our reporting units reflect numerous assumptions that are subject to various risks and uncertainties, including key assumptions regarding each reporting unit’s expected growth rates and operating margin, expected length and severity of the impact from the COVID-19 pandemic, the shape and timing of the subsequent recovery and the competitive environment, as well as other key assumptions with respect to matters outside of our control, such as discount rates and market comparables. It requires significant judgments and estimates and actual results could be materially different than the judgments and estimates used to estimate fair value. Future events and changing market conditions may lead us to re-evaluate the assumptions used to estimate the fair values of our reporting units, particularly the assumptions related to the length and severity of the COVID-19 pandemic and the shape and timing of the subsequent recovery, which may result in a need to recognize additional goodwill impairment charges that could have a material adverse effect on our results of operations.

Valuation of Investments in Private Companies

See Note 5 to our Consolidated Financial Statements for additional information related to the investments in private companies. See Note 6 to our Consolidated Financial Statements for additional information on fair value measurements, including the three levels of inputs to measure fair value. When inputs that are observable, either directly or indirectly (observable market data), is available at the measurement date and is not significantly adjusted using unobservable inputs, the observable inputs would be classified as Level 2 inputs. When little or no market data is available, the fair value of these investments are measured using unobservable inputs ("Level 3 inputs").

As of December 31, 2020, our investments measured using Level 3 inputs primarily consisted of preferred stock investments in privately-held companies that were classified as either debt securities or equity securities without readily determinable fair values. Fair values of privately held securities are estimated using a variety of valuation methodologies, including both market and income approaches. We have used valuation techniques appropriate for the type of investment and the information available about the investee as of the valuation date to determine fair value. Recent financing transactions in the investee, such as new investments in preferred stock, are generally considered the best indication of the enterprise value and therefore used as a basis to estimate fair value. However, based on a number of factors, such as the proximity in timing to the valuation date or the volume or other terms of these financing transactions, we may also use other valuation techniques to supplement this data, including the income approach. In addition, an option-pricing model ("OPM") is utilized to allocate value to the various classes of securities of the investee, including the class owned by us. The model includes assumptions around the investees’ expected time to liquidity and volatility.

Our investment in preferred shares of Grab Holdings Inc., which was classified as debt securities for accounting purposes at December 31, 2020, had an aggregate estimated fair value of $200 million at December 31, 2020. We measured this investment using Level 3 inputs and management's estimates that incorporated the current market participant expectations of future cash flows considered alongside recent financing transactions of the investee and other relevant information. In December 2021, pursuant to a business combination transaction involving Grab Holdings Inc., Grab Holdings Limited (“Grab”) and Altimeter Growth Corp. (the "Grab Transaction"), the preferred shares were converted to Class A ordinary shares of Grab and such ordinary shares began publicly trading on the NASDAQ Stock Market. As a result, the Company's investment was classified as equity securities with readily determinable fair values (see Note 5 to our Consolidated Financial Statements). At December 31, 2021, the investment had a fair value of $301 million.

For our investment in the equity securities of DiDi Global Inc. ("DiDi"), considering the impact of the COVID-19 pandemic (see Note 2 to our Consolidated Financial Statements), we performed an impairment analysis as of March 31, 2020 that resulted in an adjusted carrying value of $400 million at each of March 31, 2020 and December 31, 2020. As a result of DiDi's initial public offering in June 2021, we reclassified our DiDi investment as equity securities with readily determinable fair values. At December 31, 2021, the investment had a fair value of $195 million.

We had $51 million invested in Yanolja Co., Ltd. ("Yanolja") at December 31, 2021 and 2020. In July 2021, Yanolja announced a new round of funding into the company. The new round of funding and certain other transactions in the equity securities of Yanolja were completed in October 2021. As a result of these observable transactions, we recorded an unrealized

46

gain of $255 million in "Other income (expense), net" in the Consolidated Statement of Operations for the year ended December 31, 2021 that resulted in an adjusted carrying value of $306 million at December 31, 2021 (see Note 5 to our Consolidated Financial Statements).

The determination of the fair values of investments in private companies, where we are a minority shareholder and have access to limited information from the investee, reflects numerous assumptions that are subject to various risks and uncertainties, including key assumptions regarding the investee’s expected growth rates and operating margin, expected length and severity of the impact of the COVID-19 pandemic on the investee and the shape and timing of the subsequent recovery, as well as other key assumptions with respect to matters outside of our control, such as discount rates and market comparables. It requires significant judgments and estimates and actual results could be materially different than those judgments and estimates utilized in the fair value estimate. Future events and changing market conditions may lead us to re-evaluate the assumptions reflected in our valuation, particularly the assumptions related to the length and severity of the COVID-19 pandemic and the shape and timing of the recovery and the overall impact on the investee’s business, which may result in a need to recognize an additional impairment charge that could have a material adverse effect on our results of operations.

Income Taxes

We determine our tax expense based on our income and statutory tax rates applicable in the various jurisdictions in which we operate. Due to the complex nature of tax legislation and frequent changes with such associated legislation, significant judgment is required in computing our tax expense and determining our tax positions. The U.S. Tax Cuts and Jobs Act (the "Tax Act") enacted in December 2017 made significant changes to U.S. federal tax law, including a one-time deemed repatriation tax imposed on accumulated unremitted international earnings, to be paid over eight years. We do not intend to indefinitely reinvest our international earnings that were subject to U.S. taxation pursuant to the mandatory deemed repatriation or subject to U.S. taxation as global intangible low-taxed income ("GILTI").

We regularly review our deferred tax assets for recoverability considering historical profitability, projected future taxable income, the expected timing of the reversals of temporary differences, and tax planning strategies and record valuation allowances as required.

We are subject to ongoing tax examinations and assessments in various jurisdictions. We have been audited in many jurisdictions and from time to time face challenges regarding the amount of taxes due. These challenges include questions regarding the timing and amount of deductions that we have taken on our tax returns. Although we believe that our tax filing positions are reasonable and comply with applicable law, we regularly review our tax filing positions, especially in light of tax law or business practice changes, and we may change our positions or determine that previous positions should be amended, either of which could result in additional tax liabilities. The final determination of tax audits or tax disputes may be different from what is reflected in our historical income tax provisions and accruals.

The evaluation of tax positions and recognition of income tax benefits require significant judgement and we consult with external tax and legal counsel as appropriate. We consider the technical merits of our tax positions along with the applicable tax statutes, related interpretations and precedents, and our expectation of the outcome of proceedings (or negotiations) with tax authorities. We recognize liabilities when we believe that uncertain positions may not be fully sustained upon audit by the tax authorities, including any related appeals or litigation processes. Liabilities recognized for uncertain tax positions are based on a two-step approach for recognition and measurement. First, we evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained based on its technical merits. Second, we measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Interest and penalties attributable to uncertain tax positions, if any, are recognized as a component of income tax expense. The tax benefits ultimately realized by us may be different than what is recorded in the financial statements due to future events such as our settling the matter with the tax authorities and our success in sustaining our tax positions.

See Notes 15 and 16 to our Consolidated Financial Statements for further information.

Contingencies

Loss contingencies (other than income tax-related contingencies disclosed above) arise from actual or possible claims and assessments and pending or threatened litigation that may be brought against us by individuals, governments, or other entities. Based on our assessment of loss contingencies at each balance sheet date, a loss is recorded in the financial statements if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. If the amount of the loss cannot be reasonably estimated, we disclose information about the contingency in the financial statements. We also disclose information in our financial statements about reasonably possible loss contingencies.

47

The determination of whether a loss is probable and whether the amount of the loss can be reasonably estimated requires significant judgment and evaluation of all the underlying facts and circumstances, including judgments about the potential actions of third-party claimants, regulatory authorities, and courts. Claims, assessments, and litigations involve significant uncertainties such as the complexity of the facts, the legal theories involved, the nature of the claims, the judgment of the courts, the applicable methodology for determining potential damages, and, in the case of class actions, whether a class action can be certified and the extent to which members of a class would or would not file a claim.

On a quarterly basis, we update our analysis and estimates considering all available information, including the impact of negotiations, settlements, rulings, and advice of legal counsel. Changes in our assessment of whether a loss is probable, our estimate of the loss, or our determination of whether the amount of loss can be reasonably estimated could have a material impact on our results of operations and financial position. Changes in our assumptions regarding a particular matter or the effectiveness of our strategies related to legal and other proceedings could also have a material impact on our results of operations and financial position. For all loss contingencies, until a matter is finally resolved, there may be an exposure to loss in excess of the liability accrued for the matter and such amounts could be material.

See Note 16 to our Consolidated Financial Statements for further information.

Results of Operations

Year Ended December 31, 2021 compared to Year Ended December 31, 2020

We evaluate certain operating and financial measures on both an as-reported and constant-currency basis. We calculate constant currency by converting our current-year period operating and financial results for transactions recorded in currencies other than U.S. Dollars using the corresponding prior-year period monthly average exchange rates rather than the current-year period monthly average exchange rates.

Operating and Statistical Metrics

Our financial results are driven by certain operating metrics that encompass the booking and other business activity generated by our travel and travel-related services. Specifically, reservations of room nights, rental car days, and airline tickets capture the volume of units booked through our OTC brands by our travel reservation services customers. Gross bookings is an operating and statistical metric that captures the total dollar value, generally inclusive of taxes and fees, of all travel services booked through our OTC brands by our customers, net of cancellations, and is widely used in the travel business. Our non-OTC brands (KAYAK and OpenTable) have different business metrics from those of our OTC brands, so search queries through KAYAK and restaurant reservations through OpenTable do not contribute to our gross bookings.

Room nights, rental car days, and airline tickets reserved through our services for the years ended December 31, 2021 and 2020 were as follows:

Room nights, rental car days, and airline tickets reserved through our services increased significantly in 2021 compared to 2020 due primarily to the significant improvement in travel demand trends since the second quarter of 2020, which was severely impacted by the COVID-19 pandemic. The year-over-year increase in airline tickets in 2021 was also driven by strong execution and growth at Priceline, which operates primarily in the U.S. domestic travel market, a market that has recovered significantly faster than the global travel market from the impact of the COVID-19 pandemic, and to a lesser extent by strong growth at Booking.com, which had a relatively small amount of airline tickets booked in 2020.

Gross bookings resulting from reservations of room nights, rental car days, and airline tickets made through our agency and merchant categories for the years ended December 31, 2021 and 2020 were as follows (numbers may not total due to rounding):

Agency gross bookings are derived from travel-related transactions where we do not facilitate payments from travelers for the services provided, while merchant gross bookings are derived from services where we facilitate payments. Agency and merchant gross bookings increased in 2021 compared to 2020 due primarily to the significant improvement in travel demand trends since the second quarter of 2020, which was severely impacted by the COVID-19 pandemic. Merchant gross bookings increased more than agency gross bookings in 2021 compared to 2020 due to the expansion of merchant accommodation reservation services at Booking.com.

Gross bookings increased in 2021 compared to 2020 due primarily to the increase in room nights, accommodation ADRs of approximately 25%, on a constant-currency basis, and the positive impact of foreign exchange rate fluctuations. Gross

49

bookings resulting from reservations of rental car days and airline tickets also increased due to higher unit growth for both services.

Revenues

Online travel reservation services

Substantially all of our revenues are generated by providing online travel reservation services, which facilitate online travel purchases between travel service providers and travelers.

Revenues from online travel reservation services are classified into two categories:

•Agency. Agency revenues are derived from travel-related transactions where we do not facilitate payments from travelers for the services provided. Agency revenues consist almost entirely of travel reservation commissions from our accommodation, rental car, and airline reservation services. Substantially all of our agency revenue is from Booking.com agency accommodation reservations.

•Merchant. Merchant revenues are derived from travel-related transactions where we facilitate payments from travelers for the services provided, generally at the time of booking. Merchant revenues are derived from transactions where travelers book accommodation, rental car, and airline reservations. Merchant revenues include:

◦travel reservation commissions and transaction net revenues (i.e., the amount charged to travelers less the amount owed to travel service providers) in connection with our merchant reservation services;

◦credit card processing rebates and customer processing fees; and

◦ancillary fees, including travel-related insurance revenues.

Advertising and other revenues

Advertising and other revenues are derived primarily from:

•revenues earned by KAYAK for (a) sending referrals to OTCs and travel service providers and (b) advertising placements on its platforms; and

•revenues earned by OpenTable for (a) restaurant reservation services (fees paid by restaurants for diners seated through OpenTable's online reservation service) and (b) subscription fees for restaurant management services.

Agency and merchant revenues increased in 2021 compared to 2020 due primarily to the significant improvement in travel demand trends since the second quarter of 2020, which was severely impacted by the COVID-19 pandemic. Merchant revenues in 2021 increased more year-over-year than agency revenues due to the expansion of merchant accommodation reservation services at Booking.com.

Advertising and other revenues increased in 2021 compared to 2020 due primarily to the significant improvement in travel and restaurant demand trends since the second quarter of 2020, which was severely impacted by the COVID-19 pandemic. In addition, since the second quarter of 2021 our advertising and other revenues benefited from fees payable by restaurants for diners seated through OpenTable's online reservation service and subscription fees for restaurant management services, as the program that waived those fees ended in March 2021.

50

Total revenues as a percentage of gross bookings was 14.3% in 2021 compared to 19.2% in 2020. In 2021, revenues as a percentage of gross bookings was negatively impacted by the timing of booking versus travel as a lower amount of gross bookings made in 2020 were related to travel in 2021 than gross bookings made in 2021 related to expected travel in 2022, which is when we expect to recognize the associated revenue. In addition, in 2020, revenues as a percentage of gross bookings was positively impacted by timing of booking versus travel as revenue benefited from travel earlier in the year before the COVID-19 pandemic, while gross bookings were more negatively impacted by a significant increase in cancellations in March and April 2020.

Our businesses outside of the U.S. accounted for approximately $9.5 billion of our total revenues in 2021, a 58% increase compared to 2020. Total revenues attributable to our U.S. businesses increased 83% in 2021 compared to 2020. Revenues attributable to our U.S. businesses in 2021 increased more year-over-year than our businesses outside of the U.S. due mainly to growth at Priceline, which operates primarily in the U.S. domestic travel market, a market that has recovered significantly faster than the global travel market from the impact of the COVID-19 pandemic.

Operating Expenses

Marketing expenses

Marketing expenses consist primarily of the costs of:

•search engine keyword purchases;

•referrals from meta-search and travel research websites;

•affiliate programs;

•offline and online brand marketing; and

•other performance-based marketing and incentives.

We adjust our marketing spend based on our growth and profitability objectives, as well as the travel demand and expected ROIs in our marketing channels. We rely on our marketing channels to generate a significant amount of traffic to our websites. In 2021, our marketing expense, which is substantially variable in nature, increased significantly compared to 2020, due primarily to the improvement in travel demand trends since the second quarter of 2020, which was severely impacted by the COVID-19 pandemic. Marketing expenses as a percentage of total gross bookings decreased in 2021 compared to 2020 due to year-over-year increases in performance marketing ROIs and favorable changes in the share of traffic by channel in 2021.

Sales and Other Expenses

Sales and other expenses consist primarily of:

•credit card and other payment processing fees associated with merchant transactions;

•fees paid to third parties that provide call center, website content translations, and other services;

•chargeback provisions and fraud prevention expenses associated with merchant transactions;

•customer relations costs; and

•provisions for expected credit losses, primarily related to accommodation commission receivables and prepayments to certain customers.

51

In 2021, sales and other expenses, which are substantially variable in nature, increased compared to 2020 due primarily to an increase in merchant transaction costs of $215 million and an increase in outsourced call center costs of $100 million. Merchant transactions increased in 2021 compared to 2020 due to the significant improvement in travel demand trends since the second quarter of 2020 and the expansion of merchant accommodation reservation services at Booking.com. The increase in merchant transaction and outsourced call center costs were partially offset by a decrease in expected credit loss expenses of $176 million in 2021 as we substantially increased our provision for expected credit losses in the first quarter of 2020 due to the COVID-19 pandemic.

Personnel

Personnel expenses consist primarily of:

•salaries;

•stock-based compensation;

•bonuses;

•payroll taxes; and

•employee health and other benefits.

Personnel expenses excluding stock-based compensation expense increased 14% in 2021 compared to 2020 due to $136 million of expense in 2021 for the return of government assistance received through various government aid programs, a $126 million benefit from government grants and other assistance recognized in 2020, and a $124 million higher bonus expense accrual, partially offset by $127 million lower salary expenses.

Certain governments passed legislation to help businesses during the COVID-19 pandemic through loans, wage subsidies, tax relief, or other financial aid. We participated in several of these programs, including the Netherlands' wage subsidy program and the United Kingdom's job retention scheme. In 2021, we voluntarily returned assistance received through various government aid programs and we recorded the $136 million in expense mentioned above to reflect the return of such assistance.

In response to the reduction in our business volumes as a result of the impact of the COVID-19 pandemic, during 2020 we took actions at all of our brands to reduce the size of our workforce to optimize efficiency and reduce costs, which resulted in annualized personnel cost savings relative to our personnel expense run rate at the end of the first quarter of 2020 of approximately $370 million. Headcount was flat year-over-year at 20,300 as of December 31, 2021, but given the timing of our restructuring actions in the second half of 2020, the average headcount for 2021 decreased about 20% compared to 2020.

Stock-based compensation expense was $370 million in 2021 compared to $233 million in 2020. The increase in stock-based compensation expense in 2021 was impacted by a reduction in stock-based compensation expense of $73 million recorded in the first quarter of 2020 as a result of reduced financial performance driven by the COVID-19 pandemic, as well as the modification of certain awards during the first quarter of 2021.

General and Administrative

General and administrative expenses consist primarily of:

•occupancy and office expenses;

52

•fees for outside professionals;

•indirect taxes such as travel transaction taxes and digital services taxes; and

•personnel-related expenses such as travel, relocation, recruiting, and training expenses.

General and administrative expenses increased in 2021 compared to 2020 due to higher fees for professional services, as well as higher indirect taxes driven by the improvement in revenue. These year-over-year increases were partially offset by the comparison to a higher level of personnel-related expenses, such as travel and entertainment costs, and occupancy and office expenses in the first quarter of 2020, prior to the onset of the COVID-19 pandemic.

Information Technology

Information technology expenses consist primarily of:

•software license and system maintenance fees;

•outsourced data center and cloud computing costs;

•payments to contractors; and

•data communications and other expenses associated with operating our services.

Information technology expenses increased in 2021 compared to 2020 due to increased payments to contractors and software license fees, some of which relate to cybersecurity and data privacy.

Depreciation and Amortization

Depreciation and amortization expenses consist of:

•amortization of intangible assets with determinable lives;

•amortization of internally-developed and purchased software;

•depreciation of computer equipment; and

•depreciation of leasehold improvements, furniture and fixtures, and office equipment.

Depreciation and amortization expenses decreased in 2021 compared to 2020 due to decreased depreciation of computer equipment, partially offset by increased internally-developed software amortization expense.

Restructuring and Other Exit Costs

Restructuring and other exit costs principally relate to the restructuring charges as a result of restructuring actions taken in response to the impact of the COVID-19 pandemic on our business. Restructuring and other exit costs decreased in 2021 compared to 2020 as these restructuring activities substantially concluded as of December 31, 2020. These restructuring

53

charges are primarily related to employee severance and other termination benefits at Booking.com (see Note 20 to the Consolidated Financial Statements).

Impairment of Goodwill

During 2020, we recorded goodwill impairment charges related to OpenTable and KAYAK, which are not tax-deductible, of $1.1 billion (see Note 11 to our Consolidated Financial Statements and Critical Accounting Estimates included in this Management's Discussion and Analysis of Financial Condition and Results of Operations).

Interest expense

Interest expense decreased for the year ended December 31, 2021, compared to the year ended December 31, 2020, primarily due to the issuance of senior notes with lower interest rates in March 2021 and the redemption of senior notes with higher interest rates in April 2021, the maturity in June 2020 and September 2021 of our convertible senior notes, partially offset by higher interest expenses associated with our outstanding senior notes and convertible senior note issued in April 2020.

Other income (expense), net

The following table sets forth the breakdown of "Other income (expense), net" for the years ended December 31, 2021 and 2020:

Interest and dividend income decreased for the year ended December 31, 2021, compared to the year ended December 31, 2020, primarily due to lower yields as well as the change in the mix of investments with increased usage of investments classified as cash equivalents.

Net losses on equity securities for the year ended December 31, 2021 are primarily related to the losses on our equity investments in Meituan and DiDi, partially offset by gains on our equity investments in Grab and Yanolja. Net gains on equity

54

securities for the year ended December 31, 2020 are principally related to the gains on our equity investment in Meituan (see Note 5 to our Consolidated Financial Statements for additional information).

Impairment of investment for the year ended December 31, 2020 related to our investment in DiDi (see Notes 5 and 6 to our Consolidated Financial Statements and Critical Accounting Estimates included in this Management's Discussion and Analysis of Financial Condition and Results of Operations for additional information).

Foreign currency transaction gains (losses) include gains of $135 million and losses of $200 million related to our Euro-denominated debt and accrued interest that were not designated as net investment hedges and foreign currency losses on derivative contracts of $30 million and $31 million for the years ended December 31, 2021 and 2020, respectively.

Loss on early extinguishment of debt is related to the redemption of our Senior Notes due April 2025 (the "April 2025 Notes") and our Senior Notes due April 2027 (the "April 2027 Notes") in April 2021 (see Note 12 to our

Consolidated Financial Statements).

Other expenses for the year ended December 31, 2021 include losses on reverse treasury lock agreements

which were designated as cash flow hedges (see Note 6 to our Consolidated Financial Statements).

Income Taxes

Our 2021 effective tax rate differs from the U.S. federal statutory tax rate of 21%, primarily due to the benefit of the Netherlands Innovation Box Tax (discussed below), partially offset by higher international tax rates and an increase in unrecognized tax benefits. Our 2020 effective tax rate differs from the U.S. federal statutory tax rate of 21%, primarily due to the non-deductible goodwill impairment charges related to OpenTable and KAYAK, U.S. federal tax associated with our international earnings, and an increase in unrecognized tax benefits, partially offset by the benefit of the Netherlands Innovation Box Tax.

Our effective tax rate was lower for the year ended December 31, 2021, compared to the year ended December 31, 2020, primarily due to the non-deductible goodwill impairment charges related to OpenTable and KAYAK that were recorded in December 31, 2020, lower U.S. federal and state tax associated with our international earnings and lower unrecognized tax benefits.

Under Dutch corporate income tax law, income generated from qualifying innovative activities is taxed at a rate of 9% ("Innovation Box Tax") for periods beginning on or after January 1, 2021, rather than the Dutch statutory rate of 25%. Previously, the Innovation Box Tax rate was 7%. Effective January 1, 2022, the Netherlands corporate income tax rate increased from 25% to 25.8%. A portion of Booking.com's earnings during the years ended December 31, 2021 and 2020 qualified for Innovation Box Tax treatment, which had a significant beneficial impact on our effective tax rates for these periods. While we expect Booking.com to continue to qualify for Innovation Box Tax treatment with respect to a portion of its earnings for the foreseeable future, the loss of the Innovation Box Tax benefit could substantially increase our effective tax rate and adversely impact our results of operations and cash flows in future periods. See Part I, Item 1A, Risk Factors - "We may not be able to maintain our 'Innovation Box Tax' benefit."

Liquidity and Capital Resources

The COVID-19 pandemic and the resulting economic conditions and government restrictions resulted in a material decrease in consumer spending and a significant decline in travel and restaurant activities and consumer demand for related services as compared to 2019 levels. Our financial results and prospects are almost entirely dependent on the sale of travel-related services.

The extent of the effects of the COVID-19 pandemic on our business, results of operations, cash flows, and growth prospects is highly uncertain and will ultimately depend on future developments. These include, but are not limited to, the severity, extent and duration of the COVID-19 pandemic, including as a result of any new variants of COVID-19 and any resurgences of the pandemic, and the availability and efficacy of vaccines and other medical interventions to prevent or alleviate COVID-19 and their impacts on the travel and restaurant industries and consumer spending more broadly. Even though we have seen some improvements in the economic and operating conditions for our business since the outset of the COVID-19 pandemic, we cannot predict the long-term effects of the pandemic on our business or the travel and restaurant industries as a whole.

Our continued access to sources of liquidity depends on multiple factors, including global economic conditions, the condition of global financial markets, the availability of sufficient amounts of financing, our ability to meet debt covenant requirements, our operating performance, and our credit ratings. If our credit ratings were to be downgraded, or financing sources were to ascribe higher risk to our rating levels or our industry, our access to capital and the cost of any financing would be negatively impacted. There is no guarantee that additional debt financing will be available in the future to fund our obligations, or that it will be available on commercially reasonable terms, in which case we may need to seek other sources of funding. In addition, the terms of future debt agreements could include more restrictive covenants than those we are currently subject to, which could restrict our business operations. For more information, see Part I, Item 1A, Risk Factors - "Our liquidity, credit ratings, and ongoing access to capital could be materially and negatively affected by the impacts of the COVID-19 pandemic."

At December 31, 2021, we had $14.3 billion in cash, cash equivalents, and short-term and long-term investments, of which approximately $7.4 billion is held by our international subsidiaries. Cash, cash equivalents, and long-term investments held by our international subsidiaries are denominated primarily in U.S. Dollars, Hong Kong Dollars, and Euros. Cash equivalents and short-term and long-term investments are principally comprised of money market funds, time deposits and certificates of deposit, convertible debt securities of Trip.com Group, equity securities of Meituan, Grab, and DiDi, and our investments in private companies (see Notes 5 and 6 to the Consolidated Financial Statements). In December 2021, we redeemed our December 2015 investment of $500 million in Trip.com Group's convertible senior notes (see Note 5 to our Consolidated Financial Statements).

At December 31, 2021, we had a remaining transition tax liability of $912 million as a result of the Tax Cuts and Jobs Act (the "Tax Act"), which included $825 million reported as "Long-term U.S. transition tax liability" and $87 million included in "Accrued expenses and other current liabilities" in the Consolidated Balance Sheet. This liability will be paid over the next five years. In accordance with the Tax Act, generally, future repatriation of our international cash will not be subject to a U.S. federal income tax liability as a dividend, but will be subject to U.S. state income taxes and international withholding taxes, which have been accrued by us.

In August 2019, we entered into a $2.0 billion five-year unsecured revolving credit facility with a group of lenders. The revolving credit facility provides for the issuance of up to $80 million of letters of credit as well as borrowings of up to $100 million on same-day notice, referred to as swingline loans. The proceeds of loans made under the facility can be used for working capital and general corporate purposes, including acquisitions, share repurchases, and debt repayments. At December 31, 2021, there were no borrowings outstanding and $4 million of letters of credit issued under the facility. The revolving credit facility contains a maximum leverage ratio covenant, compliance with which is a condition to our ability to borrow thereunder. In 2020, we amended the revolving credit facility to (i) suspend the maximum leverage ratio covenant through and including the three months ending March 31, 2022, which was replaced with a $4.5 billion minimum liquidity covenant based on unrestricted cash, cash equivalents, short-term investments, and unused capacity under this revolving credit facility and (ii) increase the permitted maximum leverage ratio from and including the three months ending June 30, 2022 through and including the three months ending March 31, 2023. We agreed not to declare or make any cash distribution and not to repurchase any of our shares (with certain exceptions including in connection with tax withholding related to shares issued to employees) unless (i) prior to the delivery of financial statements for the three months ending June 30, 2022, we have at least $6.0 billion of liquidity on a pro forma basis, based on unrestricted cash, cash equivalents, short-term investments, and unused capacity under this revolving credit facility and (ii) after the delivery of financial statements for the three months ending June 30, 2022, we are in compliance on a pro forma basis with the maximum leverage ratio covenant then in effect. Such restriction

56

ends upon delivery of financial statements required for the three months ending June 30, 2023, or we have the ability to terminate this restriction earlier if we demonstrate compliance with the original maximum leverage ratio covenant in the revolving credit facility. Beginning with the three months ending June 30, 2022, the minimum liquidity covenant will cease to apply and the maximum leverage ratio covenant, as increased, will again be in effect. At December 31, 2021, we were in compliance with the minimum liquidity covenant. There can be no assurance that we will be able to meet either the minimum liquidity covenant or the maximum leverage ratio covenant, as applicable, at any particular time, and our ability to borrow under the revolving credit facility depends on compliance with the applicable covenant. Further, the lenders have the right to require repayment of any amounts borrowed under the facility if we are not in compliance with the applicable covenant (see Note 12 to the Consolidated Financial Statements).

In September 2021, in connection with the maturity of our Convertible Senior Notes due September 2021, we paid $1.0 billion to satisfy the aggregate principal amount due and an additional $86 million conversion premium in excess of the principal amount.

In March 2021, we issued Senior Notes due March 2025 with an interest rate of 0.1% for an aggregate principal amount of 950 million Euros and Senior Notes due March 2028 with an interest rate of 0.5% for an aggregate principal amount of 750 million Euros. The proceeds from the issuance of these Senior Notes issued in March 2021 were used to redeem the April 2025 Notes and the April 2027 Notes. In April 2021, we paid $2.0 billion to redeem the April 2025 Notes and the April 2027 Notes.

At December 31, 2021, we had outstanding senior notes with varying maturities for an aggregate principal amount of $11.1 billion, with $2.0 billion payable within the next twelve months. The senior notes had a cumulative interest to maturity of $1.2 billion, with $233 million payable within the next twelve months. See Note 12 to the Consolidated Financial Statements for additional information related to our debt arrangements, including principal amounts, interest rates, and maturity dates.

During the year ended December 31, 2021, we repurchased 71,494 shares of our common stock for an aggregate cost of $162 million to satisfy employee withholding tax obligations related to stock-based compensation. At December 31, 2021 and 2020, we had a remaining aggregate amount of $10.4 billion authorized by our Board of Directors to repurchase our common stock. We resumed repurchases in early 2022 under this authorization and, as of February 22, 2022, have repurchased approximately $500 million of our common stock in the first quarter of 2022. We expect to complete repurchases under the remaining authorization within the next three years assuming the travel recovery continues and we are able to meet our minimum liquidity covenant under the revolving credit facility. See Note 12 to the Consolidated Financial Statements for a description of the impact of the 2020 credit facility amendment on our ability to repurchase shares.

In November 2021, we entered into an agreement to acquire global flight booking provider, Etraveli Group, for approximately 1.6 billion Euros ($1.9 billion). Completion of this acquisition is subject to certain closing conditions, including regulatory approvals.

In December 2021, we paid $1.2 billion, net of cash acquired, to acquire Getaroom, a business-to-business distributor of hotel rooms.

In September 2016, we signed a turnkey agreement to construct an office building for Booking.com’s future headquarters in the Netherlands for 270 million Euros ($307 million). Upon signing this agreement, we paid 43 million Euros ($48 million) for the acquired land-use rights. In addition, since signing the turnkey agreement we have made several progress payments principally related to the construction of the building. As of December 31, 2021, we had a remaining obligation of 15 million Euros ($17 million) related to the turnkey agreement, which will be paid through 2022, when we anticipate construction will be complete. In addition to the turnkey agreement, we have a remaining obligation at December 31, 2021 to pay 68 million Euros ($77 million) over the remaining initial term of the acquired land lease, which expires in 2065. We have made and will continue to make additional capital expenditures to fit out and furnish the office space. At December 31, 2021, we had 20 million Euros ($23 million) of outstanding commitments to vendors to fit out and furnish the office space. See Note 16 to our Consolidated Financial Statements for additional information related to our commitments and contingencies.

At December 31, 2021, we had lease obligations of $561 million, with $155 million payable within the next twelve months. See Note 10 to the Consolidated Financial Statements for more information on our obligation related to operating leases.

At December 31, 2021, we had, in the aggregate, $154 million of non-cancellable purchase obligations individually greater than $10 million payable over the next five years, of which $41 million are payable within the next twelve months. The purchase obligations are primarily related to sponsorship and cloud hosting arrangements. The purchase obligations disclosed

57

here are those related to agreements to purchase goods and services that are enforceable and legally binding, that specify all significant terms, including the quantities to be purchased, price provisions, and the approximate timing of the transaction.

At December 31, 2021, there were standby letters of credit and bank guarantees of $511 million issued on our behalf. These are obtained primarily for regulatory purposes and payment guarantees to third-party payment processors.

Marketing expenses and personnel expenses are the most significant operating expenses for our business. We rely on marketing channels to generate a significant amount of traffic to our websites. We have established widely used and recognized e-commerce brands through marketing and promotional campaigns. See our Consolidated Statements of Operations and "Trends" and "Results of Operations" within Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional information on marketing expenses and personnel expenses including stock-based compensation expenses.

We believe that our existing cash balances and liquid resources will be sufficient to fund our operating activities, capital expenditures, and other obligations through at least the next twelve months. However, if we are not successful in generating sufficient cash flow from operations or in raising additional capital when required in sufficient amounts and on terms acceptable to us, we may be required to reduce our planned capital expenditures and scale back the scope of our business plans, either of which could have a material adverse effect on our business, our ability to compete or our future growth prospects, financial condition, and results of operations. If additional funds were raised through the issuance of equity securities, the percentage ownership of our then current stockholders would be diluted. We may not generate sufficient cash flow from operations in the future, revenue growth or sustained profitability may not be realized, and future borrowings or equity sales may not be available in amounts sufficient to make anticipated capital expenditures, finance our strategies, or repay our indebtedness.

Cash Flow Analysis

Net cash provided by operating activities for the year ended December 31, 2021 was $2.8 billion, resulting from net income of $1.2 billion and a favorable impact from adjustments for non-cash items of $1.4 billion, and a favorable net change in working capital and other long-term assets and liabilities of $269 million. Non-cash items were principally associated with net losses on equity securities, deferred income tax benefit, depreciation and amortization, stock-based compensation expense and other stock-based payments, loss on early extinguishment of debt, and operating lease amortization. For the year ended December 31, 2021, accounts receivable increased by $1.0 billion and deferred merchant bookings and other current liabilities increased by $1.5 billion, primarily due to increases in business volumes.

Net cash provided by operating activities for the year ended December 31, 2020 was $85 million, resulting from net income of $59 million and a favorable impact from adjustments for non-cash items of $1.0 billion, partially offset by an unfavorable net change in working capital and long-term assets and liabilities of $1.0 billion. Non-cash items were principally associated with net gains on marketable equity securities, impairment of goodwill, depreciation and amortization, provision for expected credit losses and chargebacks, stock-based compensation expense and other stock-based payments, deferred income tax expense, and unrealized foreign currency transaction losses related to Euro-denominated debt. For the year ended December 31, 2020, prepaid expenses and other current assets decreased by $161 million, primarily due to a refund for overpayment from a vendor and lower prepayment to third-party payment processors due to decreases in business volumes as a result of the COVID-19 pandemic. For the year ended December 31, 2020, accounts receivable decreased by $891 million and deferred merchant bookings and other current liabilities decreased by $2.3 billion primarily due to decreases in business volumes as a result of the COVID-19 pandemic.

Net cash used in investing activities for the year ended December 31, 2021 was $1.0 billion, resulting from the acquisition of Getaroom of $1.2 billion, proceeds from sales and maturities of investments of $508 million, net of purchases of $17 million, and purchase of property and equipment of $304 million. Net cash provided by investing activities for the year ended December 31, 2020 was $2.6 billion, resulting from the proceeds from sales and maturities of investments of $3.0 billion, net of purchases of $74 million, and the purchase of property and equipment of $286 million. Cash invested in the purchase of property and equipment for the years ended December 31, 2021 and 2020 includes payments of $52 million related to the turnkey agreement for constructing Booking.com's future headquarters.

Net cash used in financing activities for the year ended December 31, 2021 was $1.2 billion, almost entirely resulting from payments for redemption and conversion of debt of $3.1 billion and payments for the repurchase of common stock of $163 million, partially offset by the proceeds from the issuance of long-term debt of $2.0 billion. Net cash provided by financing activities for the year ended December 31, 2020 was $1.5 billion, almost entirely resulting from the proceeds from the

58

issuance of long-term debt of $4.1 billion, partially offset by payments for the repurchase of common stock of $1.3 billion and payments for the conversion of convertible notes of $1.2 billion.

For a discussion of our liquidity and capital resources as of and our cash flow activities for the fiscal year ended December 31, 2019, see Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on February 24, 2021.

Contingencies

French tax authorities conducted audits of Booking.com for the years 2003 through 2012, 2013 through 2015, and 2016 through 2018. In December 2015, the French tax authorities issued Booking.com assessments for unpaid income and value added taxes ("VAT") related to tax years 2006 through 2012 for approximately 356 million Euros ($403 million), the majority of which represents penalties and interest. The assessments assert that Booking.com had a permanent establishment in France. In December 2019, the French tax authorities issued an additional assessment of 70 million Euros ($80 million), including interest and penalties, for the 2013 year asserting that Booking.com had taxable income attributable to a permanent establishment in France. The French tax authorities also have issued assessments totaling 39 million Euros ($45 million), including interest and penalties, for certain tax years between 2011 and 2015 on Booking.com's French subsidiary asserting that the subsidiary did not receive sufficient compensation for the services it rendered to Booking.com in the Netherlands. In December 2021, the French tax authorities issued assessments on Booking.com’s French subsidiary totaling 78 million Euros ($88 million), including interest and penalties, for the tax years 2016 through 2018 again asserting that the subsidiary did not receive sufficient compensation for the services it rendered to Booking.com. As a result of a formal demand from the French tax authorities for payment of the amounts assessed against Booking.com for the years 2006 through 2012, in January 2019, we paid the assessments of approximately 356 million Euros ($403 million) in order to preserve our right to contest those assessments in court. The payment, which is included in "Other assets, net" in the Consolidated Balance Sheets at December 31, 2021 and 2020, does not constitute an admission that we owe the taxes and will be refunded (with interest) to us to the extent we prevail. In December 2019 and October 2020, we initiated court proceedings with respect to certain of the assessments. Although we believe that Booking.com has been, and continues to be, in compliance with French tax law, and we are contesting the assessments, during the three months ended September 30, 2020, we contacted the French tax authorities regarding the potential to achieve resolution of the matter through a settlement. After assessing several potential outcomes and potential settlement amounts and terms, an unrecognized tax benefit in the amount of 50 million Euros ($59 million) was recorded during the year ended December 31, 2020, of which the majority was included as a partial reduction to the tax payment recorded in "Other assets, net" in the Consolidated Balance Sheets at December 31, 2021 and 2020. In December 2020, the French Administrative Court (Conseil d’Etat) delivered a decision in the "ValueClick" case that could have an impact on the outcome in our case. After considering the potential adverse impact of the new decision on the potential outcomes for the Booking.com assessments, we currently estimate that the reasonably possible loss related to VAT is approximately 20 million Euros ($22 million). For additional information related to the French and other tax assessments, see Note 16 to our Consolidated Financial Statements and Part I, Item 1A, Risk Factors - "We may have exposure to additional tax liabilities."

Beginning in 2014, Booking.com received several letters from the Netherlands Pension Fund for the Travel Industry (Reiswerk) ("BPF") claiming that Booking.com is required to participate in the mandatory pension scheme of the BPF with retroactive effect to 1999, which has a higher contribution rate than the pension scheme in which Booking.com is currently participating. BPF instituted legal proceedings against Booking.com and in 2016 the District Court of Amsterdam rejected all of BPF’s claims. BPF appealed the decision to the Court of Appeal, and, in May 2019, the Court of Appeal also rejected all of BPF’s claims, in each case by ruling that Booking.com does not meet the definition of a travel intermediary for purposes of the mandatory pension scheme. BPF then appealed to the Netherlands Supreme Court. In April 2021, the Supreme Court overturned the previous decision of the Court of Appeal and held that Booking.com meets the definition of a travel intermediary for the purposes of the mandatory pension scheme. The Supreme Court ruled only on the qualification of Booking.com as a travel intermediary for the purposes of the mandatory pension scheme, and did not rule on the various other defenses we brought forward against BPF's claims. The Supreme Court referred the matter to another Court of Appeal that will have to assess the other defenses we brought forward if BPF were to proceed with the litigation. We intend to pursue a number of defenses in any subsequent proceedings and may ultimately prevail in whole or in part. While we continue to believe that Booking.com is in compliance with its pension obligations and that the Court of Appeal could ultimately rule in favor of Booking.com, given the Supreme Court’s decision, we believe it is probable that we have incurred a loss related to this matter. We are not able to reasonably estimate a loss or a range of loss because there are significant factual and legal questions yet to be determined in any subsequent proceedings. As a result, as of December 31, 2021, we have not recorded a liability in connection with a potential adverse ultimate outcome to this litigation. However, if Booking.com were to ultimately lose and all of BPF’s claims were to be accepted (including with retroactive effect to 1999), we estimate that as of December 31, 2021, the maximum loss, not including any potential interest or penalties, would be approximately 289 million Euros ($328 million). Such estimated potential loss increases as Booking.com continues not to contribute to the BPF and depends on Booking.com’s applicable

59

employee compensation after December 31, 2021. For additional information related to the pension matter and our other contingent liabilities, see Note 16 to our Consolidated Financial Statements.
