Booking Holdings Reports Financial Results for 2^nd Quarter 2018

NORWALK, CT – August 9, 2018. . . Booking Holdings Inc. (NASDAQ: BKNG) today reported its 2^nd quarter 2018 financial results. Second quarter gross travel bookings for Booking Holdings Inc. (the "Company," "Booking Holdings," "we," "our" or "us"), which refers to the total dollar value, generally inclusive of taxes and fees, of all travel services booked by its customers, net of cancellations, were $23.9 billion, an increase of 15% over a year ago (approximately 11% on a constant-currency basis).

Booking Holding's total revenues for the 2^nd quarter were $3.5 billion as compared to gross profit of $3.0 billion, a 20% increase from the prior year (approximately 16% on a constant-currency basis). Net income in the 2^nd quarter was $977.4 million, a 36% increase versus the prior year. Net income was $20.13 per diluted share, a 40% increaseas compared to the prior year. Net income in the 2^nd quarter of 2018 includes approximately $22 million of net unrealized gains on marketable equity securities during the period, pursuant to the adoption of a new accounting update effective for periods beginning after December 31, 2017.

Non-GAAP net income in the 2^nd quarter was $1.0 billion, a 32% increase versus the prior year. Non-GAAP net income was $20.67 per diluted share, a 36% increase compared to $15.14 per diluted share a year ago. Adjusted EBITDA for the 2^nd quarter was $1.3 billion, a 35% increase versus a year ago. Non-GAAP net income and adjusted EBITDA exclude net unrealized gains on marketable equity securities of approximately $22 million. The section below entitled "Non-GAAP Financial Measures" provides definitions and information about the use of non-GAAP financial measures in this press release, and the attached financial and statistical supplement reconciles non-GAAP financial information with Booking Holdings' financial results under GAAP.

"Booking Holdings achieved strong results for the second quarter," said Glenn Fogel, Chief Executive Officer of Booking Holdings. "Adjusted EBITDA and non-GAAP EPS were up year-over-year 35% and 36%, respectively." Looking forward, Mr. Fogel said, "We will continue to execute on our long-term strategy to drive profitable growth and invest in capabilities to increase customer loyalty and build a larger direct business."

Current Revenue Recognition Standard

Effective January 1, 2018, the Company adopted the current revenue standard, Accounting Standards Update 2014-09 ("Current Revenue Standard"). Under the Current Revenue Standard, the Company recognizes substantially all of its revenue at check-in, rather than at check-out, as it had in the past under the previous revenue standard ("Previous Revenue Standard"). Total revenues for the 2^nd quarter of 2018 under the Current Revenue Standard were approximately the same as what gross profit for the 2^nd quarter of 2018 would have been if reported under the Previous Revenue Standard.

In addition, revenues from Name Your Own Price^® (“NYOP") transactions are now presented on a net basis, with the amounts remitted to the travel service providers reported as a reduction to merchant revenues. Therefore, the Company no longer presents cost of revenues or gross profit.

The year over year growth rates for 2018 compare total revenues in 2018 to gross profit in 2017. The adoption of the Current Revenue Standard, which as mentioned above had an insignificant impact on total revenues in the 2^nd quarter of 2018, also had an immaterial impact on the growth rate when comparing total revenues for the 2^nd quarter of 2018 under the Current Revenue Standard to gross profit for the 2^nd quarter of 2017 reported under the Previous Revenue Standard.

Booking Holdings' guidance for the 3^rd quarter of 2018 is as follows:

	Guidance Ranges
(U.S. Dollars in millions, except per share amounts)	Low			High
Metrics
Year over year growth - Room nights booked	6		%	9		%
Year over year growth - Total gross travel bookings	3		%	6		%
Year over year growth - Total gross travel bookings (constant currency)	5		%	8		%
GAAP
Year over year growth - Revenue (1)	6		%	9		%
Year over year growth - Revenue (constant currency) (1)	8		%	11		%

Non-GAAP Net income (2)	$	1,760		$	1,810
Non-GAAP Net income per diluted share(3)	$	36.70		$	37.70
Adjusted EBITDA	$	2,300		$	2,360
(1) Growth rates compare the 3rd quarter of 2018 forecasted revenue under the current revenue standard to the 3rd quarter of 2017 gross profit as reported under the previous revenue standard.
(2) Assumes an estimated effective tax rate for the 3rd quarter of 2018 of approximately 21%.
(3) Assumes a fully diluted share count of approximately 48.0 million shares.
(4) Guidance for the 3rd quarter of 2018 for GAAP net income and net income per diluted share exclude the impact of unrealized gains and losses on marketable equity securities which are not predictable.

The Company estimates that total revenues recognized at check-in will be approximately 1% lower in the 3^rd quarter of 2018 and approximately 5% higher in the 4^th quarter of 2018 when compared to the same quarters in 2018 if revenues were recognized at check-out.

Non-GAAP adjustments for amortization expense of intangible assets, non-cash interest expense related to the amortization of debt discount and the tax impact of these non-GAAP adjustments are expected to increase non-GAAP net income over GAAP net income by approximately $40 million in the 3^rd quarter of 2018, before considering the impact of unrealized gains or losses on marketable equity securities which are not predictable.

Adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) is comprised of GAAP net income excluding depreciation and amortization expense, interest income, interest expense, unrealized gains and losses on marketable equity securities and income tax expense. Adjusted EBITDA is estimated to be higher than GAAP net income by approximately $580 million to $590 million in the 3^rd quarter of 2018, before considering the impact of unrealized gains or losses on marketable equity securities which are not predictable.

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: Non-GAAP total revenues, adjusted EBITDA, non-GAAP net income, non-GAAP net income per share and free cash flow (net cash provided by 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 non-

GAAP 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 next-period 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 EBITDA, non-GAAP net income 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, net income or cash flow from operations 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.

Non-GAAP net income is net income with the following adjustments:

• excludes the impact, if any, of significant charges or benefits associated with judgments, rulings and/or

settlements related to travel transaction tax (e.g., hotel occupancy taxes, excise taxes, sales taxes, etc.)

proceedings or other litigation,

• excludes the impact of significant loyalty program adjustments, such as the favorable $27 million adjustment to total revenues in the 1^st quarter of 2018 related to recently introduced changes to OpenTable’s loyalty program,

• excludes amortization expense of intangible assets,

• excludes the impact, if any, of significant charges related to the impairment of goodwill or intangible assets,

• excludes non-cash interest expense related to the amortization of debt discount and gains or losses on

early extinguishment of debt, if any, related to our convertible debt,

• excludes the impact, if any, of significant gains or losses on the sale of cost-method investments and

significant charges related to other-than-temporary impairments of such investments,

• excludes, if any, unrealized gains and losses on marketable equity securities, that are recognized in

net income (beginning in the 1^st quarter of 2018), and

• the income tax impact of the non-GAAP adjustments mentioned above.

In addition to the adjustments listed above regarding non-GAAP net income, adjusted EBITDA excludes

depreciation expense, interest income, interest expense and income tax expense.

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 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.

The attached financial and statistical supplement includes reconciliations of our financial results under GAAP to non-GAAP financial information for the three and six months ended June 30, 2018 and 2017.

⁽¹⁾Amounts may not total due to rounding.

⁽²⁾ 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 by our customers, net of cancellations.

⁽³⁾ For periods ending prior to January 1, 2018, gross profit has been adjusted to reflect the reclassification of certain prior period expenses from "cost of revenues" to "sales and other expense" to conform to the current period presentation.

⁽⁴⁾ For periods beginning after December 31, 2017, the Company records amounts remitted to travel service providers as a reduction to merchant revenues and therefore no longer presents cost of revenues or gross profit. The year over year growth rate compares total revenues in 2018 reported under the current revenue standard to gross profit in 2017 reported under the previous revenue standard.
