(Adds settlement winning preliminary approval, updated Facebook share price and market value)
By Jonathan Stempel
Feb 26 (Reuters) - Facebook Inc and Chief Executive Mark Zuckerberg have reached a $35 million settlement of class-action litigation accusing them of hiding worries about the social media company's growth prior to its May 2012 initial public offering.
The settlement was filed on Monday in the federal court in Manhattan and won preliminary approval from U.S. District Judge Robert Sweet.
It amounts to a small fraction of Facebook's current market value of roughly $537 billion as of Monday's market close.
Shareholders led by the Arkansas Teacher Retirement System and Fresno County Employees' Retirement Association in California accused Facebook of concealing internal concerns about how growth in mobile devices might reduce revenue, even as it quietly warned its banks to cut their forecasts.
Unlike in 2012, the Menlo Park, California-based company now generates most of its revenue from mobile devices and has estimated that mobile advertising generated more than 86 percent of its $40.7 billion total revenue in 2017.
The settlement resolves claims against Facebook, officials including Chief Operating Officer Sheryl Sandberg and director Peter Thiel, and bank underwriters covering a five-day period surrounding the $16 billion IPO, from May 17 to May 21, 2012.
Facebook made its market debut on May 18 of that year at $38 per share and saw its share price languish below that level for more than a year before it rebounded.
"Resolving this case is in the best interests of the company and our shareholders," Associate General Counsel Sandeep Solanki said in a statement.
A lawyer for the shareholders did not immediately respond to a request for comment.
Sweet scheduled a Sept. 5 hearing to consider final settlement approval.
The accord was reached after mediation, and provides an average recovery of about 11 cents per share, or 7 cents per share after possible legal fees and costs, court papers show.
Insurers may cover some of the payout.
Lawyers for the shareholders called the settlement "fair, reasonable, and adequate," citing the risk of a loss at trial, according to court papers.
Facebook shares rose $1.64 on Monday to close at $184.93 on the Nasdaq.
The case is In re: Facebook Inc IPO Securities and Derivative Litigation, U.S. District Court, Southern District of New York, No. 12-md-02389. (Reporting by Jonathan Stempel in New York; Editing by Cynthia Osterman)
