WEIGHT WATCHERS ANNOUNCES PRELIMINARY RESULTS OF ITS SELF-TENDER OFFER

New York, January 19, 2007 — Weight Watchers International, Inc. (NYSE: WTW) announced today the preliminary results of its “modified Dutch Auction” tender offer, which expired at 12:00 midnight, New York City time, on January 18, 2007. The Company expects to accept for payment an aggregate of 8,300,000 shares of its common stock at a purchase price of $54.00 per share. These shares represent approximately 8.5% of the Company’s outstanding shares as of November 30, 2006.

The Company has been informed by the depositary for the tender offer that the preliminary proration factor for the tender offer is approximately 99.1%. Based on the preliminary count by the depositary for the tender offer, an aggregate of 8,683,754 shares were properly tendered and not withdrawn at or below a price of $54.00, including 3,092,360 shares that were tendered through notice of guaranteed delivery. The number of shares to be purchased, the price per share and the proration factor are preliminary. The determination of the final number of shares to be purchased, the final price per share and the final proration factor is subject to confirmation by the depositary of the proper delivery of the shares validly tendered and not withdrawn. The actual number of shares validly tendered and not withdrawn, the final price per share and the final proration factor will be announced following the completion of the confirmation process. Payment for the shares accepted for purchase and return of all other shares tendered and not accepted for purchase will occur promptly thereafter and is currently anticipated to occur on January 26, 2007. Any shares properly tendered and not purchased due to proration or conditional tenders will be returned to the tendering shareholders.

Additionally, based on the preliminary count, the Company expects to purchase 10,206,436 shares from Artal Holdings Sp. z o.o., its majority shareholder, at a purchase price of $54.00 per share. The Company previously announced an agreement with Artal to purchase a number of shares of common stock at the price established by the tender offer so that Artal’s percentage ownership interest in the Company’s outstanding shares

of common stock after the tender offer and such purchase from Artal will be substantially equal to its current level. The determination of the final number of shares to be purchased from Artal and the final price per share is subject to the determination of the final number of shares to be purchased in the tender offer and the final price per share in the tender offer.
