21st Century Fox has been consistently trying to avoid selling to Comcast because Fox officials believe a merger with the largest US cable company may not be approved by the federal government.
Comcast and the Walt Disney Company have been in a bidding war for the assets being sold by Fox. The most recent development came last week when Fox leadership rejected a $65 billion offer from Comcast and accepted Disney's new offer of $71.3 billion.
Comcast could try to outbid Disney again and seek approval from Fox shareholders. But Fox and Disney said in a new Securities and Exchange Commission filing that a Comcast/Fox deal would face a difficult path to regulatory approval.
The Fox board prefers to merge with Disney in part because "a strategic transaction with Comcast would be subject to a greater degree of regulatory uncertainty, including the possibility of an outright prohibition and a higher risk of divestitures and delay to closing, as compared to a strategic transaction with Disney," the filing said.
Comcast/NBC merger conditions expire
Comcast's "asset mix" would make a Comcast/Fox deal difficult, the filing said. This likely refers to Comcast's status as the largest home Internet provider and the largest cable TV provider in the US. A Comcast/Fox agreement would let Comcast decide how much to charge other cable, satellite, and online TV providers for access to that programming.
Comcast has already expanded into programming, notably with its 2011 purchase of NBCUniversal and its ownership of regional sports networks. The US government imposed conditions on the Comcast/NBC merger in order to prevent anti-competitive behavior, but those conditions are expiring entirely in September of this year.
