A dozen state attorneys general just threw a wrench into what would be one of the largest media mergers in history. The coalition, led by California AG Rob Bonta, filed an antitrust lawsuit on July 13 to block Paramount Skydance’s acquisition of Warner Bros. Discovery, a deal valued between $81B and $111B.

The US Department of Justice already cleared this merger. The states decided they disagreed.

The financial pressure cooker

If the deal doesn’t close on schedule, Paramount could be on the hook for quarterly penalty payments to Warner Bros. Discovery shareholders. Those payments could total $650M starting in October, according to the company’s own disclosures.

Paramount’s response to the lawsuit leaned heavily on the human cost angle, arguing that the legal challenge could adversely affect entertainment workers who stand to benefit from a combined entity with deeper pockets and broader distribution reach.
