It is unclear whether Warner Bros would buy Paramount Global or its parent company, National Amusements Inc (NAI), the source told Reuters. Axios said both options were on the table.

Warner Bros and Paramount did not immediately respond to Reuters’ requests for comment.

Paramount is controlled by the Shari Redstone-led media company that owns 77% of Paramount’s Class A voting shares.

Talks between Warner Bros and Paramount are still early, and may not ultimately result in a deal, according to the Axios report.

In April last year, AT&T’s WarnerMedia unit and Discovery merged to become Warner Bros Discovery, with a portfolio that included Discovery Channel, Warner Bros. Entertainment, CNN, HBO, Cartoon Network; streaming services Discovery+ and HBO Max; and franchises such as ‘Batman’ and ‘Harry Potter’.

Earlier on Wednesday, Bloomberg News reported Paramount was in talks to sell its Black Entertainment Television network to a management-led investor group.

There have been other reports of takeover interest in Paramount, which has a market cap of $10.5 billion and long-term debt of about $15.6 billion.

Warner Bros shares closed about 6% lower on Wednesday, while Paramount shares fell about 2%.
