Breakup Fees Put a Number on Walking Away From a Signed Deal
A merger agreement is a promise with a penalty attached. The size of that penalty is negotiated hard, because it decides whether a better offer can still arrive.
Two Directions
A breakup fee, formally a termination fee, is paid by the target to the buyer if the target walks away, usually to accept a superior offer from someone else.
A reverse breakup fee runs the other way, paid by the buyer to the target if the buyer fails to complete, most often because regulators blocked the deal or financing collapsed.
Both exist because signing costs real money. Advisers, lawyers, financing commitments, and months of management attention are spent between signing and closing, and the party left behind has also lost the option to pursue other transactions during that period.
Typical Sizing
Target side breakup fees in United States public deals have generally sat in the range of 1 to 4 percent of equity value, clustering around 3 percent.
Reverse fees are frequently larger, particularly where antitrust risk is significant, because the target is accepting a real chance the deal simply never closes through no fault of its own.
| Fee type | Typical range | Triggered by |
|---|---|---|
| Target breakup fee | 1 to 4 percent | Accepting a superior proposal |
| Reverse fee, financing | 3 to 6 percent | Buyer funding fails |
| Reverse fee, regulatory | Can exceed 6 percent | Antitrust block |
Why the Size Is Fought Over
The target's board owes duties to shareholders, which include not foreclosing a better price. A breakup fee is a cost imposed on any competing bidder, since a rival must effectively pay the fee on top of its own offer.
Set at 2 percent, the fee is a speed bump. Set at 12 percent, it is a wall, and no rival will bother. Delaware courts have struck down or criticised fees judged to be preclusive, treating them as a defensive measure that must be reasonable in relation to the threat.
The breakup fee is not really about compensating the buyer. It is about how much friction the board is willing to place in front of a better offer, and that is a question about the board's duties.
The Regulatory Version
Reverse fees for antitrust failure allocate a risk neither party controls. A target agreeing to a deal that regulators may block is taking its business off the market for a year, absorbing the disruption of a pending acquisition, and possibly losing customers who hesitate during the uncertainty.
The failed acquisition of a major wireless carrier in 2011 produced one of the largest such payments, combining cash and spectrum assets worth billions, after the government sued to block it. The recipient emerged materially stronger, which is the point of the mechanism.
Buyers pursuing deals with obvious competition concerns should expect to pay for that risk in advance, and the size of the reverse fee is a reasonable read on how likely the parties privately think a challenge is.
The Fee Is Not the Only Remedy
Agreements specify whether the fee is the exclusive remedy or whether the wronged party may also sue for damages or seek specific performance, meaning a court order compelling completion.
Sellers generally want specific performance, since being paid a fee is worse than getting the deal done. Buyers want the fee to cap their exposure. Where an agreement lands on this is often more consequential than the headline number.
Go Shop Interaction
Some agreements include a reduced fee during an initial go shop window, when the target may actively solicit competing offers. A lower fee during that period and a full fee afterwards is a compromise between allowing genuine price discovery and giving the first bidder deal certainty.
A very low go shop fee paired with a short window is often cosmetic, providing the appearance of market testing without meaningful opportunity for a rival to complete diligence.
The Bottom Line
Breakup fees price the right to walk away and allocate the risk that a deal fails for reasons outside either party's control. Target fees around 3 percent are standard, larger fees invite legal challenge as preclusive, and reverse fees scale with regulatory risk. Read them alongside the remedies clause, because whether the fee is the only recourse frequently matters more than its size.
