WSJ - June 25 - IAC/InterActiveCorp has followed through on a long-expected plan to pursue an IPO of Match Group. Mr. Diller, IAC’s chairman, isn’t breaking up with Match Group entirely. The company is planning to sell a stake of less than 20% in the division, which includes fitness and educational businesses. Investors cheered the move, sending IAC’s shares up $3.93, or 5.1%, to $81.19. Match Group is IAC’s strongest growth engine, bringing in 29% of overall revenue in 2014. For all the buzz around dating sites, there hasn’t yet been a significant win for VCs in terms of an IPO, said Mark Brooks, CEO of Courtland Brooks, an adviser to dating companies. That’s been a challenge for entrepreneurs. "We need a success story, and I think the Match Group could be a success story," he said. If the IPO doesn’t go over well with investors, "we can kiss the opportunity of future funding goodbye."
