Playboy Enterprises said on Monday that it had agreed to be taken private by Icon Acquisition Holdings, a partnership run by Hugh Hefner, in a deal valuing the company at $177 million.

The offer price of $6.15 a share is 18 percent above Playboy’s closing price of $5.20 on Friday. Shares rose 17.31 percent, to $6.10, in premarket trading on Monday.

Mr. Hefner is currently the editor in chief and chief creative officer of the media company, which publishes Playboy magazine and produces television programs. He created the magazine in 1953, and took Playboy Enterprises public in 1971.

“With the completion of this transaction, Playboy will come full circle, returning to its roots as a private company,” Mr. Hefner said in a statement. “I believe this agreement will give us the resources and flexibility to return Playboy to its unique position and to further expand our business around the world.”

Mr. Hefner controls 69.5 percent of the company’s voting shares and 27.7 percent of its nonvoting shares. Plainfield Asset Management, which holds 19.05 percent of the company, has agreed to the deal.

Icon received equity backing for the deal from the private investment firm Rizvi Traverse Management, and a financing commitment from Jefferies & Company. The Playboy board unanimously approved the deal on Sunday, and it is expected to close Jan. 21.

“This would bring an end to a period of uncertainty for the company and provide the right ownership structure to develop the business,” said Ben Kohn, a Rizvi partner.

Scott Flanders, chief executive of Playboy, said that its “strategy is to transform Playboy into a brand management company.”

Playboy hired Lazard as financial adviser and Skadden, Arps, Slate, Meagher & Flom as counsel. A committee of board directors hired Raine Securities as adviser and Kaye Scholer as counsel. Moelis served as financial adviser and Munger, Tolles & Olson as counsel to Mr. Hefner. Jefferies & Company and Sheppard, Mullin, Richter & Hampton advised and counseled Rizvi Traverse.
