Oprah Winfrey’s investment in Weight Watchers two and a half years ago is paying off.

The lifestyle company reported last week strong earnings and sales, as well as an increase in subscribers. The stock jumped 5 percent on Friday because of the news, CNN Money reports.

Winfrey bought $43.5 million in stocks in 2015 and joined the company’s board and appears in its ads. Her investment is now worth more than $400 million.

Mindy Grossman, who joined the company last year as its CEO, told analysts in February that “healthy is the new skinny.”

“Our purpose is to inspire healthy habits for real life for people, families, communities, the world,” Grossman said on a conference call Thursday. “We want to own the healthy kitchen” and “make healthy cooking accessible to everyone.”

Winfrey has been credited with the brand’s resurgence since signing on as a spokeswoman. The company’s stock was trading at $7 when she decided to invest, it is now trading at $68 as of Tuesday.

In March, Winfrey unloaded 2 million of her shares in the company, earning about $110 million.

She still owns 5.5 million shares, per CNN Money.
