The New York company, which Liberty Media Corp. is seeking to take over, said Wednesday that its search committee is looking at candidates from within the company, including Meyer, as well as outside the company to fill the CEO post on a permanent basis. Liberty CEO Greg Maffei is leading Sirius' CEO search committee.
Meyer, the president of sales and operations, is also joining the board.
Karmazin had been CEO since 2004, overseeing the 2008 merger between Sirius and its rival, XM Satellite Radio and then leading the combined company. Sirius XM Radio Inc. announced in October that he planned to step down as CEO and a board member. There had long been speculation he would leave because of the expected takeover by Liberty Media.
Liberty rescued Sirius XM from bankruptcy in 2009 with $530 million in exchange for a 40-percent equity stake. Liberty has been buying shares for months in its quest for a controlling stake in the company. The Federal Communications Commission must approve Liberty's takeover.
Shares of Sirius added a penny to $2.97 in midday trading.
