A group of lenders to WW International, operator of the well-known Weight Watchers franchise, has hired Gibson Dunn to prepare for debt talks with the struggling diet company, according to 9fin sources.

The organization comes as WW is battling subscriber losses amidst the advent of weight loss drugs such as Ozempic and Wegovy.

Investors are also rattled by Oprah Winfrey’s plan to step down from WW’s board in May, after the entertainment mogul revealed that she’s using a weight loss medication. Winfrey is also planning to donate her holdings in the company’s stock to the National Museum of African American History and Culture.
