Six Hundred Billion Dollars Is Sitting in a Queue
Twenty announced transactions are waiting for permission to happen. The delay is not bureaucratic sloth, it is three separate review regimes that did not exist in this form a decade ago.

As of this month roughly twenty announced mergers and acquisitions worth in the region of $600 billion were still waiting to close. Signed, in many cases approved by shareholders, and unable to proceed.
That is a great deal of capital in suspension, and the reasons are structural rather than accidental. Three distinct review regimes now sit between an announcement and a completion, and only one of them is the traditional one.
One: competition review got more assertive
Antitrust authorities in the United States, the European Union and the United Kingdom have all become more willing to challenge, and more willing to challenge on theories that would not have been pursued fifteen years ago.
The older approach concentrated on price. If a merger would not obviously raise consumer prices, it generally proceeded. The newer approach considers effects on suppliers, on labour markets, on innovation and on the ability of new entrants to compete at all.
Whether that is a correction of decades of permissiveness or an overreach is genuinely contested among economists. What is not contested is that it takes longer.
Two: national security screening expanded enormously
This is the change most people underestimate.
A decade ago, foreign investment screening applied narrowly to defence and a handful of sensitive sectors. It now routinely covers telecommunications, ports, energy networks, semiconductors, data centres, biotechnology and anything holding significant personal data.
The effect is that a transaction with no competition problem whatsoever can still be delayed or stopped because of who the buyer is and where their capital comes from. e&'s accumulation of a Vodafone stake ran into exactly this in the United Kingdom, and the position was eventually sold rather than grown, as we set out in the e& exit.
For Gulf acquirers this is now a routine planning consideration in Europe rather than an occasional obstacle.
Three: sub-national challenges
The newest and least predictable layer. In the United States, coalitions of state attorneys general have begun bringing their own actions against transactions, independently of the federal position.
This is difficult for acquirers because it breaks the assumption that clearance is a single negotiation. A dozen states asking a federal judge to pause the Paramount and Warner Bros. Discovery merger is exactly this pattern, arriving after shareholder approval and after clearance in Britain.
What the delay actually costs
More than the legal fees, and the legal fees are considerable.
The target degrades. A company in limbo cannot make long-term decisions, loses staff who will not wait, and defers investment. A year of that leaves a materially worse business than the one that was agreed to be bought.
Financing gets expensive. Debt packages are committed at announcement and carry costs. If rates move against the acquirer during an eighteen-month review, the deal arithmetic changes and cannot easily be renegotiated.
Competitors get a warning. A pending acquisition tells every rival exactly what the acquirer intends to do, with enough notice to respond.
How long do large mergers take to close now?
For deals above roughly fifty billion dollars, twelve to twenty-four months from announcement is now normal, and longer is not unusual where multiple jurisdictions and national security review are involved. Mid-market transactions below about five billion frequently close in three to six months. That divergence is the defining feature of the current market: the same regulatory environment barely touches one end and dominates the other.
Can a deal be abandoned because of delay alone?
Yes, and it happens. Merger agreements contain outside dates, after which either party may walk away, and prolonged review pushes transactions towards them. Delay also changes the commercial logic: a target that made sense at one price in a given market may not at the same price eighteen months later. Break fees exist precisely because this risk is real and someone has to carry it, and negotiating who pays what if regulators say no is now one of the more contested parts of any large agreement.
What are companies doing about it?
Adapting the deals rather than fighting the regime. Three responses are visible. Acquirers are buying smaller and more often, staying below the thresholds that trigger the most intensive review. They are structuring around control, taking minority positions and commercial partnerships instead of outright ownership where the target sits in a sensitive sector. And they are pre-negotiating remedies, offering divestitures at announcement rather than waiting to be asked. The August deal run, covered in the monthly roundup, is almost entirely composed of the first of those.
Where this ends up
Probably in a two-speed market that persists, because none of the three review regimes is likely to loosen soon.
The consequence worth thinking about is that scale becomes harder to buy and easier to build. If acquiring a large competitor takes two years and might fail, the alternative of investing the same capital organically starts to look less slow by comparison than it once did.
That is not obviously a bad outcome. It is simply a different one from the market that corporate strategy departments were built for.
