SAN FRANCISCO — Sheryl Sandberg, the No. 2 executive at Facebook owner Meta, is stepping down. Sandberg has served as chief operating officer at the social media giant for 14 years. She’s leaving Meta in the fall and will continue to serve on the company’s board.

Meta CEO Mark Zuckerberg said in his own Facebook post that Javier Olivan will serve as Meta’s new COO, although it will be a different job than the one Sandberg held for the past 14 years.

While Sandberg has long been Zuckerberg’s No. 2 in the company’s Menlo Park, Calif., headquarters, she also had a very public-facing job, meeting with lawmakers, holding focus groups and speaking out on topics such as women in the workplace and, most recently, abortion.

Sandberg, who lost her husband Dave Goldberg suddenly in 2015, said she is “not entirely sure what the future will bring.”
