The buyout firm Apollo Global Management has approached Nexstar to express interest in acquiring it.

Reuters reports that the approach comes a year after Nexstar’s $2.3 billion acquisition of peer Media General turned it into one of the largest U.S. broadcasters.

Nexstar wants to add scale as advertisers move their spending to digital and mobile platforms.

Apollo has teamed up with P2 Capital Partners LLC, another investment firm that already owns a small stake in Nexstar, the sources said. Nexstar has not yet engaged in sale talks and there is no certainty it will entertain an offer, the sources added.

The sources asked not to be identified because the deliberations are confidential.

Apollo declined to comment while Nexstar and P2 did not immediately respond to requests for comment.

Nextstar generated adjusting earnings of $743 million last year, up 83 percent year on year, and $469 million in free cash flow, making it an attractive asset for private equity buyers.
