Break Fee

Last updated 8 October 2026

A break fee is a payment one party in a deal agrees to make to the other if the transaction fails for specified reasons. It is most common in mergers and acquisitions, where a target company agrees to compensate a buyer if the board walks away or accepts a rival offer.

What it means

Break fees exist because deals are expensive to pursue. A serious bidder spends heavily on advisers, financing commitments and management time long before completion, and wants some protection if the target changes its mind.

There are two directions to keep straight. A break fee is normally payable by the target to the buyer, while a reverse break fee is payable by the buyer to the target, typically if financing collapses or a regulator blocks the deal.

The size is usually expressed as a percentage of equity value. Targets' break fees commonly sit in the low single digits, while reverse break fees are often larger because the risks they cover, such as antitrust refusal, are more serious and entirely outside the target's control.

Fees are also deliberately limited so they do not become a deterrent to competing bids. Some jurisdictions cap them by rule or by takeover code, and directors elsewhere have to satisfy themselves that agreeing a fee is consistent with their duty to seek the best outcome for shareholders.

For anyone reading a deal announcement, the break fee tells you something useful about perceived risk. A large reverse break fee usually means both sides expect a difficult regulatory review, and a small target fee often signals a board keen to keep the door open for other bidders.

In practice

Real-world examples

Example 1

A pharmaceutical group agrees to buy a smaller rival and negotiates a 2.5% break fee. When a private equity firm tables a higher offer eight weeks later, the target pays the fee out of the increased proceeds and its board recommends the new bid.

Example 2

A technology acquisition with obvious competition concerns carries a reverse break fee of $500,000,000. The buyer's board accepts it because the seller refused to sign up to a long regulatory review without compensation for the disruption.

Example 3

A commercial property sale includes an exclusivity agreement with a small break fee covering the buyer's survey and legal costs. When the seller accepts a higher offer during the exclusivity period, the fee reimburses the disappointed buyer's actual spend.

Think of it

Imagine putting down a non-refundable holding deposit on a house. If you simply change your mind and walk away, the seller keeps the deposit to compensate for taking the house off the market.

Formula

Calculation

Break fee = agreed percentage x equity value of the transaction, where equity value is the price paid for the shares rather than the enterprise value including debt. A bidder agrees to acquire a listed logistics group for $2,400,000,000 in equity value. The merger agreement sets a target break fee of 3%, payable if the target's board withdraws its recommendation or accepts a superior proposal, so the fee is $2,400,000,000 x 0.03 = $72,000,000. Because the deal faces a serious competition review, the target negotiates a reverse break fee of 6% payable if the regulator blocks it, giving $2,400,000,000 x 0.06 = $144,000,000. If a rival then bids $2,600,000,000, that rival is effectively paying $2,600,000,000 plus the $72,000,000 the target must hand over, so its true cost of winning is $2,672,000,000.

Case study

Seen in the real world

Halcyon Distribution is a fictional listed company invented for this illustrative example. It agreed a $2,400,000,000 takeover by a larger competitor and signed a merger agreement containing a 3% break fee of $72,000,000 alongside a 6% reverse break fee of $144,000,000.

The fictional board's reasoning was documented carefully. The 3% figure was low enough that a genuinely interested rival could still bid, while the larger reverse fee compensated shareholders for the eight to twelve months of uncertainty and lost momentum if the competition authority refused clearance.

A rival did emerge at $2,600,000,000, and in this illustrative story the higher price more than covered the $72,000,000 that Halcyon then had to pay the original bidder. The directors' notes recorded the principle plainly: a break fee should price the disruption of failure without pricing out a better offer.

Watch out

Common mistakes

  • Assuming a break fee is a penalty for bad behaviour. It is compensation for costs and disruption, and it is triggered by defined events rather than by any finding of fault.
  • Mixing up break fees and reverse break fees. The first flows from target to buyer, the second from buyer to target, and they cover very different risks.
  • Calculating the fee on enterprise value. Break fees are almost always set against equity value, so including assumed debt overstates the amount.

Questions

People also ask

What is a typical break fee size?

Target break fees commonly fall in the range of 1% to 3% of equity value, while reverse break fees are often considerably higher.

Why are break fees capped in some markets?

Because an excessive fee would discourage competing offers and could conflict with directors' duty to obtain the best available terms for shareholders.

Does a break fee guarantee a deal completes?

No, it only prices the consequences of failure, and a determined rival bidder or a firm regulatory objection will still end a transaction.
