Paramount Won Warner Bros.; Twelve States Halted the Deal

Warner Bros. Discovery signed an all-stock merger with Netflix at the end of 2025: announced, executed, under way.

Then Paramount Skydance took an all-cash offer straight to shareholders and raised it in February to $31 a share. The WBD board judged it superior to the signed Netflix agreement; Netflix declined to go higher and walked away.

In June, the Justice Department cleared the transaction. On July 13, the attorneys general of twelve states, California among them, sued to block the merger. A federal judge halted it.

On the day this piece was written, WBD stock traded meaningfully below the $31 offer. That gap is not a pricing error but the market doing arithmetic on probability.

How a Signed Deal Came Undone

In public-company M&A signing marks the middle of the story, not the end. A board's duty to shareholders does not switch off at signature, and a better offer must be considered.

Merger agreements handle this with an explicit carve-out and charge for it with a break fee: accepting the better offer is permitted, but not free.

The Mechanism: The Merger Spread Is a Probability Calculation

If the offer is $31, why isn't the stock $31?

This arithmetic is merger arbitrage, a professional discipline. But the lesson is not the number. When a headline says a company is being bought for $31 a share while the stock sits at $26, that gap measures how little the market believes it.

A price drifting toward the offer means the case is seen as weakening, away from it strengthening. No commentary updates that fast.

The Tender Offer: Going Around the Board

What Paramount launched in December was technically a tender offer: the buyer goes straight to shareholders, without waiting to reach terms with the target's board.

In a conventional merger the boards agree first, then shareholders vote; a tender offer inverts that, and if enough shares are tendered the board is effectively cornered.

That is how Paramount broke in while a signed Netflix agreement still stood. The board's only recourse is to tell shareholders not to tender, and that fails when the rival bid is cash and richer.

A break fee sets the price of walking away: if the target accepts a better offer and leaves the table, it pays the original buyer a fixed sum.

The clause does two jobs. It protects the original buyer, who spent months and real money on diligence. It also sets a threshold for any rival, whose offer has to cover the fee as well.

If the Justice Department Cleared It, How Can States Block It?

In the United States antitrust law is enforced from two directions. Federally it falls to the Justice Department and the Federal Trade Commission. At state level it falls to state attorneys general, whose standing to sue does not depend on federal clearance.

Federal sign-off is not a permit but a statement that one authority is not objecting. There is more than one door, and every one has to open separately.

Every bar is the same length because every gate is equally necessary: clearing four of five does not mean the deal is 80% done, it means it is not done.

Why Twelve States

State attorneys general acting together is a strategy, not only a show of force: one state's suit concerns a narrow geography, twelve can assert a nationwide market definition.

So the merging parties cannot buy their way through one state at a time. Settling with one plaintiff does not bind the other eleven, and any concession becomes the floor for the next.

For the companies that means a longer clock — and here the clock is a weapon.

The merger agreement expires on March 4, 2027, extendable once automatically to June 4, 2027.

That date may matter more than the lawsuit. Antitrust litigation can run for years while the life of a contract is fixed; the plaintiffs do not need to win in court, only to run out the clock.

What Happens If the Deal Breaks

The second half of the calculation is the one readers skip: what the shares are worth if it does not close.

When a merger collapses the stock reverts to its standalone value, but never one-for-one: months have passed, the business has changed, the sector repriced, the company run under uncertainty.

A buyer who walked away can come back: Netflix's refusal was an answer to one price on one day, not a permanent verdict. If the deal breaks and the shares fall, the same asset becomes interesting again.

So the instinct that a broken merger sends a stock "to zero" is wrong: the break scenario has a price of its own, the second term in the equation above.

The Takeaway: An Announced Deal Is Not a Completed Deal

Merger coverage is written in the language of certainty — "is acquiring," "is merging" — but between announcement and closing lie months, sometimes years, and several veto points.
