NEW YORK (Reuters) - Apollo Global Management (NYSE:APO) and Irth Capital Management have approached Papa John’s International (NASDAQ:PZZA) for a deal that would take the U.S. pizza chain private, two people familiar with the matter said on Wednesday. The investment firms’ joint bid would value Papa John’s, the world’s third-largest pizza delivery company, just above $60 per share, said the people, who asked not to be identified because the deal is private. Papa John’s declined to comment. Apollo and Irth did not immediately respond to requests for comment.
