Breakup Fee
A breakup fee (or termination fee) is paid by one party to the other when they terminate a signed deal — compensates for wasted time and deal costs.
Full Definition
A breakup fee (also called a termination fee) is a contractual payment one party must make to the other if the deal fails to close under specified circumstances. In M&A, breakup fees most commonly obligate the target company (seller) to pay the buyer if the seller backs out — typically to pursue a superior offer from a competing acquirer. A reverse breakup fee obligates the buyer to pay the seller if the buyer fails to close, most often due to financing failure or regulatory block.
Standard breakup fee mechanics: In public company M&A, the standard seller-side breakup fee is 2–4% of deal enterprise value — calibrated to compensate the buyer for its due diligence costs and opportunity cost while being low enough that a genuinely superior offer remains viable. Courts, particularly in Delaware, scrutinize breakup fees above 4% as potentially preclusive to competing bids — a seller's board that agrees to a fee so large it deters competing offers may be breaching its fiduciary duty. Private company deals typically range 1–5% and courts apply less scrutiny.
When a breakup fee is triggered: The triggering events for a seller-side breakup fee typically include: the seller's board changing or withdrawing its deal recommendation, the seller entering into an agreement for an alternative transaction, and the deal failing to receive shareholder approval after a board recommendation change. The fee is not triggered merely because a competing offer appears — the seller must actually walk from the deal or recommend an alternative.
Reverse breakup fee: The reverse breakup fee (buyer pays seller) has become standard in large leveraged buyouts where financing risk is the primary closing uncertainty. If the buyer's lenders won't fund, the buyer pays the reverse breakup fee rather than being forced to close. This effectively makes the reverse breakup fee the buyer's option price — they can walk from the deal for a defined cost. Sellers should ensure the reverse breakup fee is large enough to genuinely compensate for deal failure, not just provide the buyer a cheap exit option.
Expense reimbursement as alternative: In smaller deals, parties sometimes use expense reimbursement provisions (the abandoning party pays the other's documented transaction costs) rather than a fixed termination fee. This is less certain (costs must be documented and may be disputed) but can be more proportionate in small transactions.
Seller vs. Buyer Perspective
The breakup fee you agree to at signing affects how freely you can respond to future offers. A large fee (3%+ on a private deal) makes it expensive to walk — and may effectively lock you in even if a significantly better offer appears. Negotiate the fee down and ensure your agreement contains a genuine fiduciary out that lets you respond to superior proposals. Also negotiate the reverse breakup fee hard: if your buyer can't close, you want the reverse fee to be meaningful compensation for the time, cost, and lost opportunities from being off the market during exclusivity.
From your perspective, the breakup fee is insurance against the seller walking for a competing offer. Size it at a level that makes the economics of abandoning your deal unattractive to the seller — but not so large that Delaware courts or regulators would view it as preclusive. For deals with financing risk, the reverse breakup fee you agree to is effectively the premium on your option to walk: make sure the business case for closing is strong enough that you're unlikely to exercise it, because paying it is an expensive loss.
Real-World Example
A $40M acquisition is signed with a 3% breakup fee ($1.2M) and a 5% reverse breakup fee ($2M). Four weeks after signing, a strategic competitor offers the seller $45M. The seller's board evaluates the superior proposal and, finding it genuinely more valuable, invokes the fiduciary out. The seller pays the $1.2M breakup fee to the original buyer and signs with the competitor. The original buyer's out-of-pocket due diligence costs were approximately $400K — the breakup fee more than covers those costs.
Why It Matters & Common Pitfalls
- !Fiduciary out provisions must be carefully drafted. A 'no-shop' provision with no meaningful fiduciary out effectively bars the seller from pursuing clearly superior offers. Sellers should insist on a genuine fiduciary out with a reasonable matching right (not a perpetual matching right) for the original buyer.
- !Reverse breakup fees can become buyer escape hatches. A reverse breakup fee that's too small — say 1–2% — is effectively a cheap exit option for a buyer who loses conviction post-signing. Size it at 4–6% of deal value in deals where buyer commitment is important to seller.
- !Fee triggers must be clearly defined. Ambiguity in what events trigger the fee creates litigation risk. Be explicit: does a board 'recommendation withdrawal' include a board that simply fails to reaffirm its recommendation on schedule? Does 'alternative transaction' include a minority investment or only a full acquisition?
- !Document costs if using expense reimbursement. If your agreement uses expense reimbursement rather than a fixed fee, keep detailed records of all transaction costs — legal, financial advisory, diligence — from the start. These records are essential to recovering costs if the agreement includes a reimbursement obligation.

Related Terms
Letter of Intent (LOI)
A preliminary document outlining the key terms of a proposed M&A transaction — price, structure, financing, timeline, and conditions — mostly non-binding but typically including binding provisions for exclusivity and confidentiality.
Material Adverse Change (MAC)
A contractual provision permitting a buyer to terminate a signed deal before closing if the target business experiences a significantly negative change — difficult to invoke successfully in court, but critical protection against catastrophic changes.
Go-shop Provision
A contract provision allowing the seller to actively solicit competing bids for a defined period after signing the definitive agreement — rare in SMB M&A but standard in some public-company and fiduciary-sensitive transactions.
Exclusivity Period
A contractual period, typically 30–90 days after LOI signing, during which the seller agrees not to solicit or negotiate with other potential buyers — the point in a deal where leverage shifts from seller to buyer.
