Check out the companies making headlines after the bell Thursday:

Herbalife shares rocketed 12 percent after it apparently neared a settlement with the Federal Trade Commission in a long-running investigation of its practices. The company said it could face a payment of about $200 million and that its discussions with the FTC are in the advanced stages.

The company also reported a beat on quarterly results. Herbalife saw earnings of $1.36 per share, excluding one-time items, on revenues of $1.12 billion for the quarter. Analysts had expected the company to report earnings of $1.09 per share on revenue of $1.07 billion.

Shares of Square plummeted 13 percent after the company posted another loss in its second-ever quarterly report. The payment processing company saw a quarterly loss of 14 cents per share on revenue of $379 million. Wall Street had expected the company to post a loss of 9 cents a share on revenues of $344 million.

GoPro shares were up as much as 7 percent before giving back the gains on the back of mixed quarterly results. GoPro posted a quarterly loss of 63 cents a share on revenues of $183.5 million. Analyst had expected a loss of 60 cents a share on $169 million in revenue, according to a consensus estimate from Thomson Reuters. For the same quarter last year, the company posted earnings of 24 cents per share on sales of $363.1 million.

Shares of Yelp jumped more than 8 percent after the company posted a strong beat on earnings. For the first fiscal quarter of 2016, Yelp saw earnings of 8 cents a share, ex-items, on revenue of $159 million. Analysts had expected the company to post a loss of 16 cents a share on revenue of $156 million.

FireEye fell more than 6 percent after the company gave weak guidance and said CEO David DeWalt would step down. The cybersecurity company said it now sees full-year revenues between $780 million and $810 million. FireEye had previously stated that it saw 2016 revenue of $815 million to $845 million.

The company said it faced headwinds from reduced spending for its security services and loss of market share to the likes of Palo Alto Networks and Proofpoint.
