What Is a Breakup Fee?
A breakup fee is a negotiated payment, written into the merger agreement, that the target owes the acquirer if the deal terminates under specified circumstances. The classic trigger is the target board exercising its fiduciary out to accept a superior proposal from a rival bidder. Other triggers can include the board changing its recommendation or shareholders voting the deal down after a competing offer has publicly surfaced.
Fee sizes cluster in a fairly tight band. Most US public company breakup fees fall between 2% and 4% of the target's equity value, with roughly 3% to 3.5% the most common zone in large deals. On a $10 billion acquisition, a 3% fee means the target would owe $300 million to walk away, a real cost but rarely enough to stop a determined competing bidder.
How Breakup Fees Work in Practice
The fee serves as deal protection for the first mover. It compensates the original buyer for its diligence costs and advisory fees, along with the risk of publicly committing to a transaction that another party then tops. It also raises the bar for interlopers, because a competing bidder effectively must offer enough extra value to absorb the fee the target will pay out upon termination.
Courts police the size. Delaware judges have generally upheld fees in the 3% to 4% range but scrutinize anything that looks preclusive, meaning so large that it deters all competing offers and effectively locks up the company. The fee usually travels with companion protections, including a no-shop covenant and matching rights that let the original buyer counter any superior proposal before losing the deal.
Why Breakup Fees Matter for Deal Teams
When a deal includes a go-shop window, agreements often use a two-tier structure: a reduced fee, frequently 50% to 65% of the full amount, applies to bidders who emerge during the go-shop period, while the full fee applies afterward. Bankers advising potential interlopers model the fee directly, since it is part of the true cost of topping an announced transaction.
Keep the direction straight in interviews: the breakup fee is paid by the target, while the reverse termination fee is paid by the buyer when it fails to close. Analysts encounter breakup fees in nearly every public merger agreement they read and compile fee-size precedents in the deal-protection benchmarking that banking and legal teams prepare during negotiations.
