The biggest media merger in a generation just hit a speed bump across the Atlantic. Paramount Skydance’s $110 billion takeover of Warner Bros. Discovery, which sailed through an eight-month US Department of Justice antitrust review, is now staring down potential intervention from the UK government over concerns about media ownership concentration.

UK Culture Secretary Lisa Nandy has signaled the deal could be referred to the Competition and Markets Authority for deeper investigation. The CMA has advanced to phase 3 diligence, with scrutiny due by August 7, 2026. For a transaction that seemed to be cruising toward a Q3 2026 close, this is the kind of complication that makes deal lawyers reach for the coffee pot.

What the deal actually looks like

Announced on February 27, 2026, the acquisition values Warner Bros. Discovery at $81 billion in equity and $110 billion in enterprise value. That works out to $31 per share for WBD stockholders, priced at roughly 7.5 times fully synergized 2026 EBITDA.

The deal’s backstory traces to Skydance Media’s earlier acquisition of Paramount Global in 2025, a transaction valued at around $8 billion that installed David Ellison as chairman and CEO of the combined Paramount Skydance entity.

WBD shareholders approved the merger in April 2026. The DOJ gave its blessing in late June 2026, concluding after extensive review that the deal was unlikely to significantly harm competition.

Why the UK matters

The UK’s interest in this deal isn’t random. Warner Bros. Discovery operates significant media properties with global reach, including CNN and HBO. The CMA’s intervention framework gives it broad authority to examine whether a merger might reduce competition or consolidate too much influence over public discourse.

The UK isn’t the only potential hurdle remaining. The deal could also prompt scrutiny from EU regulatory bodies, and US state attorneys general retain the ability to mount their own legal challenges independent of the DOJ’s decision.

The competitive landscape that forced this play

WBD had originally explored plans to separate into distinct streaming and studio businesses. That plan was shelved when Paramount Skydance came calling with its offer, and reportedly other major players including Netflix had also expressed interest in various configurations.

What this means for investors

The DOJ clearance was the single biggest regulatory milestone for this transaction. US regulators looked at this for eight months and decided it wouldn’t meaningfully harm competition. The August 7 diligence deadline is the next date to circle on the calendar.

It’s also worth noting what this deal doesn’t include: any crypto or digital asset component, signaling that the biggest players in entertainment still see their future in content and distribution scale.
