The Priceline Group Reports Financial Results for 3^rd Quarter 2017

NORWALK, CT – November 6, 2017. . . The Priceline Group Inc. (NASDAQ: PCLN) today reported its 3^rd quarter 2017 financial results. Third quarter gross travel bookings for The Priceline Group (the "Company," the "Group," "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 $21.8 billion, an increase of 18% over a year ago (approximately 16% on a constant-currency basis).

The Group's gross profit for the 3^rd quarter was $4.4 billion, a 22% increase from the prior year (approximately 19% on a constant-currency basis). International operations contributed gross profit in the 3^rd quarter of $4.0 billion, a 23% increase versus a year ago (approximately 20% on a constant-currency basis). Net income in the 3^rdquarter was $1.7 billion, a 240% increase versus the prior year, which included a $941 million goodwill impairment charge. Net income was $34.43 per diluted share, a 240% increase as compared to the prior year.

Non-GAAP net income in the 3^rd quarter was $1.8 billion, a 19% increase versus the prior year. Non-GAAP net income was $35.22 per diluted share, a 19% increase compared to $29.69 per diluted share a year ago. Adjusted EBITDA for the 3^rd quarter was $2.2 billion, an 18% increase versus a year ago. 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 the Group's financial results under GAAP.

"The Priceline Group delivered solid growth and operating results during our seasonally busy third quarter," said Glenn Fogel, Chief Executive Officer of The Priceline Group. "Globally, our accommodation business booked 178 million room nights in the third quarter, up 19% over the same period last year. Booking.com showed continued momentum with approximately 1.5 million properties on its platform, up 41% over last year. This represents 26.9 million potentially bookable rooms, which we believe to be the largest, and most diverse, selection of instantly bookable accommodations in the world."

Looking forward, Mr. Fogel said, "As we look to the fourth quarter and beyond, we will continue to focus on making the right investments across our brands - in people, systems, and marketing - to continue to grow our business for the long term."

The Group's guidance for the 4^th quarter of 2017 is as follows:



	Guidance Ranges
(U.S. Dollars in millions, except per share amounts)	Low			High
Metrics
Year over year growth - Room nights booked	8		%	13		%
Year over year growth - Total gross travel bookings	9.5		%	14.5		%

GAAP
Year over year growth - Gross profit	10.5		%	15.5		%
Year over year growth - Gross profit (constant currency)	6		%	11		%
Net income	$	625		$	655
Net income per diluted share⁽¹⁾	$	12.60		$	13.20

Non-GAAP

Non-GAAP Net income per diluted share⁽¹⁾	$	13.40		$	14.00
Adjusted EBITDA	$	870		$	910

⁽¹⁾ Assumes a fully diluted share count of approximately 49.7 million shares.

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 4^th quarter.

Adjusted EBITDA excludes depreciation and amortization expense, interest income, interest expense and income tax expense. These adjustments are estimated to increase adjusted EBITDA over GAAP net income by approximately $245 million to $255 million in the 4^th quarter.

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 Group uses the following non-GAAP financial measures: Adjusted EBITDA, non-GAAP net income and non-GAAP net income per share. 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 Group 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 Group believes that these non-GAAP financial measures are useful for analysts and investors to evaluate the Group’s ongoing operating performance because they facilitate comparison of the Group’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 than those calculated by the Group). These non-GAAP financial measures, in particular adjusted EBITDA and non-GAAP net income, are not intended to represent funds available for the Group's 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 our 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,


•	excludes amortization expense of intangible assets,


•	excludes the impact, if any, of significant charges related to the impairment of goodwill, such as the $941 million non-cash goodwill impairment charge recorded in the 3^rd quarter of 2016,


•	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, and


•	the 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 nine months ended September 30, 2017 and 2016.
