Weight Watchers Names James Chambers President and CEO

Weight Watchers International, Inc. (NYSE: WTW) today announced that James Chambers has been appointed President and Chief Executive Officer effective July 30, 2013. He has also been elected to the Company’s Board of Directors as of such date. Chambers succeeds David Kirchhoff who notified the Company’s Board of Directors of his resignation, effective as of July 30, 2013, as Chief Executive Officer and a Director of the Company to pursue other opportunities.

Kirchhoff remarked, “I have been with Weight Watchers for fourteen years, six and a half as CEO. I am proud of all that we have accomplished – notably building the Weight Watchers Online business, modernizing the brand and laying the groundwork for our healthcare strategy – but now is the right time for me to embark on something entirely new. Since Jim joined us in January as President and Chief Operating Officer, I have had the pleasure of working closely with him. He has shown tremendous leadership and has brought a fresh perspective to the business and its future opportunities. I am proud to leave this very special company in such capable hands.”

Ray Debbane, Chairman of Weight Watchers’ Board of Directors commented, “We thank Dave for all of his contributions over the years, beginning with the successful build of the Weight Watchers Online business. We wish Dave well in all his future endeavors and know he will remain a Weight Watchers member and passionate ambassador for our brand.” Debbane continued, “Jim’s strengths in both operations and consumer insights make him uniquely qualified to lead this business and take it to new levels going forward. He has a successful track record of developing and executing winning strategies and we have every confidence in his ability to drive the Company’s long-term growth.”

Chambers said, “Weight Watchers has such a tremendous global opportunity to make an even greater impact in people’s lives and I am honored to lead this organization. I look forward to working further with the entire Weight Watchers team to drive our business execution and next stage of growth.”
