Priceline.com Reports Financial Results For 1st Quarter 2007

Gross travel bookings increase 33.7% year over year;
 European gross travel bookings grow 91% versus 2006

     NORWALK, Conn., May 8, 2007 . . . Priceline.com Incorporated (Nasdaq: PCLN) today reported its financial results for the 1st quarter 2007.  Gross travel bookings for the 1st quarter, which refers to the total dollar value, inclusive of all taxes and fees, of all travel services purchased by consumers, rose 33.7% year-over-year to $998 million.

Priceline.com had GAAP revenues in the 1st quarter of $301.4 million, a 24.6% increase over a year ago.  Priceline.com’s GAAP gross profit for the 1st quarter was $119.7 million, up 65.7% from the prior year. Priceline.com had a GAAP net loss for the 1st quarter 2007 of $16.3 million or $0.44 per diluted share.  The GAAP results include, among other things, the impact of litigation settlement expenses and an excise tax refund.  Several days ago, priceline.com announced that it had agreed to settle the securities class action litigation that was filed against the Company in 2000 and pay the class plaintiffs $80 million, of which $30 million will be funded by priceline.com’s insurance carriers.  Priceline.com incurred a 1st quarter 2007 net charge of approximately $55 million to settle the litigation and cover expenses.  Priceline.com also announced that in March and April it received notices from the Internal Revenue Service that the Company’s previously disclosed refund request for excise taxes paid on merchant airline tickets had been approved for payment.  As a result, priceline.com recorded in the 1st quarter $15.9 million in revenue and $2.8 million in interest income related to the March IRS notice and expects to record approximately $3 million of additional income in the 2nd quarter 2007 related to the April notice, including estimated accrued interest.

Priceline had pro forma revenues in the 1st quarter of $285.5 million, an 18.0% increase over a year ago.  Pro forma gross profit for the 1st quarter 2007 was $103.8 million, an increase of 43.1% over the same period in the prior year.  Pro forma net income for the quarter was $17.4 million, or $0.43 per diluted share, which compares to $7.6 million, or $0.19 per diluted share in the same period a year ago.  First Call analyst consensus for the 1st quarter 2007 was $0.27 per diluted share. The section below entitled “Non-GAAP Financial Measures” provides a definition and information about the use of pro forma financial measures in this press release and the attached financial and statistical supplement reconciles pro forma financial information with priceline.com’s financial results under GAAP.

 “First quarter pro forma earnings growth exceeded our expectations in both the United States and Europe,” said priceline.com President and Chief Executive Officer Jeffery H. Boyd.  “In Europe, Booking.com benefited from 91% growth in gross travel bookings as we continued to build the business across Europe.  In the United States, pro forma earnings growth was driven by 8% growth in merchant gross travel bookings and greater efficiencies in marketing, which cost gross travel bookings, but significantly decreased acquisition costs.”

Looking towards the 2nd quarter 2007, Mr. Boyd said, “We expect to see continued growth in our European operations from increased penetration of larger markets, geographic expansion and integration initiatives.  In our domestic business, we believe the merchant business and marketing efficiencies will continue to drive domestic earnings growth; however, we believe that the impact of lower margins on retail airline tickets and the higher return hurdles we have imposed on marketing investment will continue to negatively impact the retail airline ticket business and, consequently, domestic gross travel bookings.  As we approach the peak summer travel season, we believe that priceline.com’s Name Your Own Price® travel services can effectively meet the needs of consumers concerned with high fuel prices and mixed economic signals and we expect to emphasize that money-saving message as the Priceline Negotiator ad campaign featuring William Shatner continues.”

Forward Guidance

For full-year 2007, priceline.com reiterated the guidance it had given the previous week in connection with the announcement to settle the 2000 securities litigation and said that it expects to generate approximately $4.1 to $4.2 billion in gross travel bookings in 2007 and to earn approximately $2.90 to $3.10 of pro forma net income per diluted share for full year 2007.  The full-year 2007 pro forma net income per share estimate is based upon an estimated pro forma fully diluted share count of 42.6 million shares.  The estimate of pro forma fully diluted share count uses actual year-to-date stock price data as well as estimated future stock prices based on the closing price of the Company’s stock as of May 7, 2007 to calculate the potential dilutive impact of stock options and convertible debt.  Any material increases or decreases in priceline.com’s stock price will impact the number of fully diluted shares outstanding, which in turn would impact the company’s net income per diluted share results.

Priceline.com said it was targeting the following for 2nd quarter 2007:

·Year-over-year increases in overall gross travel bookings of approximately 23% to 28%.

·Year-over-year increases in gross travel bookings from Booking.com of approximately 72% to 76%.

 (more)

2

·Year-over-year increase in pro forma revenue of approximately 10% to 15%.

·Year-over-year increase in pro forma gross profit of approximately 34% to 38%.

·Pro forma net income of between $0.80 and $0.90 per diluted share.

Pro forma net income per diluted share guidance for the 2nd quarter and full-year 2007:

·excludes cash expenses associated with the settlement of the 2000 securities litigation,

·excludes the cash benefit associated with the refund of excise taxes (and related accrued interest) paid on merchant airline tickets,

·excludes non-cash amortization expense of acquisition-related intangibles,

·excludes non-cash stock-based compensation expense,

·excludes option payroll tax expense,

·excludes non-cash income tax expense and reflects the impact on income taxes of the pro forma adjustments,

·excludes non-cash preferred stock dividends,

·includes the additional impact on minority interest expense of the pro forma adjustments described above,

·includes the anti-dilutive impact of the “Conversion Spread Hedges” (see below) on outstanding diluted common shares outstanding, and

·includes the dilutive impact of additional warrants and shares of unvested restricted stock and restricted stock units because pro forma net income has been adjusted to exclude preferred stock dividend and stock-based compensation.

When aggregated, the foregoing adjustments are expected to increase pro forma net income over GAAP net income by approximately $12 million for the 2nd quarter 2007 and $70 million for full-year 2007.  On a per share basis, the Company estimates GAAP net income of approximately $0.52 to $0.62 per diluted share for the 2nd quarter 2007 and GAAP net income of approximately $1.25 to $1.45 per diluted share for the full-year 2007.

Non-GAAP Financial Measures

Pro forma revenue, Pro forma gross profit, pro forma net income and pro forma net income per share are “non-GAAP financial measures,” as such term is defined by the Securities and Exchange Commission, and may differ from non-GAAP financial measures used by other companies.  Priceline.com believes that pro forma revenue, pro forma gross profit, pro forma net income and pro forma net income per share that exclude certain non-cash or non-recurring income or expense items are useful for investors to evaluate priceline.com’s future on-going performance because they enable a more meaningful comparison of priceline.com’s projected cash earnings and performance with its historical results from prior periods.  Pro forma financial information is adjusted for the following items:

·Cash expenses associated with the settlement of the 2000 securities litigation are excluded because of the non-recurring nature of the settlement.

·Cash benefit associated with the refund of excise taxes paid on merchant airline tickets that was approved for payment by the Internal Revenue Service is excluded because of its non-recurring nature.

·Amortization expense of acquisition-related intangibles is excluded from pro forma gross profit and pro forma net income because it does not impact cash earnings.

·Stock-based compensation expense and the non-cash expense associated with the payment of preferred stock dividends are excluded from pro forma net income because they do not impact cash earnings and are reflected in earnings per share through increased share counts.

·Option payroll tax expense is excluded because the expense is driven primarily by stock option exercise activity and the market price of priceline.com’s common stock and often shows volatility unrelated to operating results.

·The restructuring charge, net is excluded because it can impact comparability of earnings with historical results from prior periods.

·Income tax (expense) benefit is adjusted for the tax impact of certain of the pro forma adjustments described above and to exclude tax expense recorded where no actual tax payments are owed because of available net operating loss carryforwards.

·Minority interest is adjusted for the impact of certain of the pro forma adjustments described above.

·Finally, for calculating pro forma net income per share:

onet income is adjusted for the impact of the pro forma adjustments described above

6

ofully diluted share count is adjusted to include the anti-dilutive impact of  the Conversion Spread Hedges that increase the effective conversion price of the 2011 Notes and 2013 Notes from their stated $40.38 conversion price to an effective conversion price of $50.47 per share.  Under GAAP, the anti-dilutive impact of the Conversion Spread Hedges is not reflected on the outstanding diluted share count until the end of the hedge when shares are delivered.

ofully diluted share count in 2006 is adjusted to exclude the impact of EITF 04-08 (“Effect of Contingently Convertible Debt on Diluted Earnings per Share”), because the common stock that underlie priceline.com’s 1% Convertible Senior Notes and priceline.com’s 2.25% Convertible Senior Notes were not issuable because our common stock did not trade above the respective contingent conversion prices.

oAll common stock warrants and shares of restricted common stock are included in the calculation of pro forma net income per share because pro forma net income has been adjusted to exclude our preferred stock dividend and stock-based compensation expense.

The presentation of this financial information should not be considered in isolation or as a substitute for the financial information prepared and presented in accordance with generally accepted accounting principles in the United States.  The attached financial and statistical supplement reconciles pro forma financial information with priceline.com’s financial results under GAAP.
