What Is a Breakup Fee (Termination Fee) in M&A?

A breakup fee — usually called a termination fee in the merger agreement — is a fixed payment the company being sold agrees to make to the buyer if the signed deal is terminated in specified situations, most often because the target's board accepts a higher bid from someone else or changes its recommendation to stockholders. It compensates the first buyer for the time, cost and lost opportunities of a deal that did not close, and it is one of the "deal protections" that sit alongside no-shop clauses, go-shop windows and match rights. A reverse termination fee runs the other way: the buyer pays the seller if the deal fails for buyer-side reasons, such as not obtaining antitrust approval. Delaware courts do not apply a fixed percentage cap. They ask whether the fee, alone and together with the other protections, is reasonable and does not preclude a higher bid or coerce stockholders.

How a termination fee works

A public-company merger agreement typically lists the events that let each side terminate, then says which of those events require a payment. The fee is a negotiated, fixed dollar amount, not an estimate calculated after the fact. Three features recur in the Delaware opinions:

• Superior-proposal trigger. In *Toys "R" Us*, the $247.5 million fee was payable "for the most part only if the Company terminated the merger agreement in order to sign up another acquisition proposal within a year."
• Expense reimbursement on a "naked no vote." If stockholders simply vote the deal down without a competing bid, many agreements pay only documented expenses. Toys "R" Us agreed to pay up to $30 million in documented expenses in that case.
• Tail provisions. A second payment can be owed if a competing deal is completed within a set period after termination. In *Brazen*, Bell Atlantic and NYNEX each agreed to pay $200 million in specified circumstances, plus an additional $350 million if a competing transaction was consummated within 18 months.

Termination fees rarely stand alone. They are negotiated together with a no-shop (no-solicitation) clause, any go-shop window, the board's fiduciary out and the buyer's match rights. Delaware courts look at the whole package.

Breakup fee vs. reverse termination fee

A 2011 Kirkland & Ellis post on the Harvard Law School Forum on Corporate Governance described reported antitrust reverse termination fees in Google/Motorola Mobility ($2.5 billion, or 20% of deal value), AT&T/T-Mobile (about $6 billion of value, or 15%) and Hertz/Dollar Thrifty ($44.6 million, about 4%). The same post stressed that a reverse fee is "just one facet (as often absent as not)" of a negotiated set of provisions — efforts covenants, divestiture commitments, closing conditions and termination triggers — that together allocate regulatory risk.

How Delaware courts review fee size

1. The fee must be reasonable, not a penalty, and not coercive. In *Brazen v. Bell Atlantic* (1997), the merger agreement itself said the fee was liquidated damages, so the Delaware Supreme Court applied the liquidated-damages test: damages must be uncertain and the amount reasonable. The $550 million two-tier fee was about 2% of Bell Atlantic's roughly $28 billion market capitalization. The Court held it was "within a range of reasonableness and is not a penalty," and that it was not coercive even though stockholders knew a "no" vote could trigger it.

2. Courts look at the fee with the other deal protections. In *Cogent* (2010), the Court of Chancery said it must review deal provisions "on its own and in combination with all others" to ensure they "are reasonable and do not preclude a higher bid from being successful."

3. What specific fees have looked like in court:

These are the numbers from those deals, not a market standard. Each opinion stresses that reasonableness depends on the specific transaction.

4. Equity value or enterprise value? In *Cogent*, the target had $513 million of cash and no material debt, so a $28.3 million fee was 3% of equity value but 6.6% of enterprise value. The court held that equity (transaction) value was the appropriate metric in that case, following *Dollar Thrifty*. In *Comverge*, the court noted it "sometimes finds" enterprise value more informative for judging a fee's preclusive effect on a rival bidder, especially for a highly leveraged target, citing *Lear*.

5. Hidden add-ons count. In *Comverge*, the buyer had made a bridge loan convertible into target stock at a discount. The court found it reasonably conceivable that the notes, together with the fee and expense reimbursement, could have prevented a topping bid; plaintiffs put the combined cost at 11.6% to 13.1% of equity value. That was a pleading-stage ruling, not a final finding, but it shows courts will add up every payment a rival bidder would effectively bear.

What to look for in a termination-fee clause

• Triggers: exactly which terminations require payment — superior proposal, change in recommendation, breach, a "naked no vote," or a deal signed within a tail period.
• Amount and base: a fixed dollar figure, and what that figure is as a share of equity value and of enterprise value.
• Two-tier fees: a lower fee for a bidder that emerged during a go-shop and a higher fee afterward (as in *Lear* and *Del Monte*).
• Expense reimbursement: whether it is capped and whether it is credited against the fee.
• Everything else a topping bidder would pay: convertible notes, options, or other side arrangements (*Comverge*).
• Reverse fee (if you are the seller): amount, triggers, and whether it is the seller's sole remedy.
• Interaction with the no-shop, fiduciary out and match rights.

When to talk to counsel

Speak with an M&A or corporate attorney (and, for litigation, a Delaware or business-litigation lawyer) if:

• your board is negotiating a merger agreement and needs to size the termination fee and expense reimbursement against the rest of the deal protections;
• you are a buyer that wants a fee large enough to compensate for a lost deal but not so large that a court might view it as preclusive;
• you are a seller weighing antitrust or financing risk and want a reverse termination fee, or want to understand whether it is your only remedy;
• you are a stockholder questioning whether deal protections left room for a higher bid;
• a competing bidder has appeared and there is a dispute over whether a fee is owed.
