A no-shop clause is a provision in a merger or acquisition agreement that stops the seller from soliciting, negotiating, or sharing confidential information with any competing bidder during a defined exclusivity period. It protects the buyer’s investment of time and money in due diligence, but almost every well-drafted no-shop carries built-in exceptions so the seller’s board can still accept a genuinely better offer if one lands on the table.
What a No-Shop Clause Actually Prohibits
Once the clause takes effect, the seller faces three overlapping restrictions.
The first is no-solicitation. The seller cannot go looking for alternative buyers, run a parallel sales process, or market the company to competitors. The restriction binds the seller’s executives and extends to its investment bankers and outside counsel, who cannot reach out to prospective bidders on the seller’s behalf.
The second is no-negotiation. Even if a third party calls unprompted with a higher number, the seller is generally barred from discussing price, structure, or terms. The conversation has to be shut down rather than used as leverage against the original buyer.
The third covers confidential information. Financial statements, customer data, operational metrics, and other proprietary material cannot be shared with anyone other than the current buyer. That lockdown keeps a competitor from gaining a window into the business during the exclusivity period.
The Window-Shop Carve-Out
Most no-shops in public company mergers include a narrow carve-out called a window-shop. The seller’s board can engage with an unsolicited third-party bidder, but only if it determines in good faith that the unsolicited offer could lead to a superior proposal and that refusing to engage would breach the board’s fiduciary duties. The board can listen to the pitch, share information under a confidentiality agreement, and negotiate within those limits.
Window-shops come with procedural strings. The seller usually must notify the original buyer promptly, disclose the identity of the competing bidder and the material terms of the offer, and hand over copies of any information shared with the new party that the original buyer hasn’t already received. Those notifications give the original buyer real-time visibility and set the stage for matching rights.
The Fiduciary Out
Directors on the seller’s board owe fiduciary duties to shareholders, and those duties don’t disappear because the company signed a no-shop. Under Delaware law, which governs most public company mergers, the board must manage the business in shareholders’ best interest. When a sale of control becomes inevitable, that obligation sharpens into what practitioners call Revlon duties: the board has to work to get the best reasonably available price, not simply rubber-stamp the first offer.
A fiduciary out reconciles the two obligations. It gives the board a contractual escape hatch to terminate the existing deal if a superior proposal emerges, provided the board follows a prescribed process. Without this exception, the no-shop could effectively force directors to recommend a lower offer over a higher one, exposing them to personal liability.
What Counts as a Superior Proposal
The bar is deliberately high. The unsolicited offer has to be financially superior to the existing deal and reasonably likely to close. A vague indication of interest or a highly conditional bid that hinges on financing the buyer hasn’t secured won’t clear it. The board must consult with both its financial advisors and legal counsel before concluding the new offer qualifies, and most agreements require that determination to be documented formally.
Matching Rights
Before the seller can walk away, the original buyer gets a chance to save the deal. The seller must notify the buyer of the superior proposal, including its material terms, and give the buyer a window, typically three to five business days, to match or improve its offer. If the buyer matches, the fiduciary out doesn’t trigger and the original deal stays intact. If the buyer declines, the seller can terminate and accept the superior proposal, subject to paying the breakup fee.
Some agreements allow multiple rounds. If the competing bidder raises its offer after the buyer matches, the clock resets and the buyer gets another chance to respond. The back-and-forth can extend the process, but tends to push the price up.
Intervening Events
A superior proposal isn’t the only reason a board might need to change course. An intervening event is a material development, unknown or unforeseeable when the agreement was signed, that fundamentally changes the calculus. The company might discover a major asset that makes the agreed price look inadequate, or a regulatory shift might dramatically alter the business outlook. Many modern agreements allow the board to withdraw its recommendation to shareholders based on an intervening event, even without a competing bid, though the procedural requirements and matching-rights obligations still apply.
Force-the-Vote Limits
Delaware law permits a merger agreement to require that the deal be submitted to shareholders even after the board withdraws its recommendation. The Delaware Supreme Court held in Omnicare v. NCS Healthcare that combining a force-the-vote provision with irrevocable shareholder voting agreements and no fiduciary out made the deal impossible to stop, which violated the board’s duties. A force-the-vote clause paired with a genuine fiduciary out generally survives scrutiny; one that eliminates every exit does not.1Justia. Delaware Code Title 8 Corporations 251
Breakup Fees When the Seller Walks
When the seller exercises a fiduciary out and terminates, it owes the buyer a breakup fee, also called a termination fee. The payment compensates the buyer for legal costs, advisory fees, management time, and the opportunity cost of a deal that fell apart. The amount is negotiated upfront and locked into the merger agreement, so both sides know the price of walking away before the ink dries.
Target termination fees in public company deals typically land between 2 and 4 percent of the transaction’s equity value. On a $500 million deal, that’s roughly $10 million to $20 million. Courts evaluate reasonableness by asking whether the fee is so large that it effectively blocks competing bids. A fee that makes it economically irrational for any rival to bid isn’t protecting the buyer’s investment; it’s locking up the deal by deterring competition, and courts have struck down fees that cross that line.
Beyond the headline fee, many agreements include separate expense reimbursement provisions that cover the buyer’s out-of-pocket accounting, legal, and advisory costs up to a negotiated cap. The obligation to pay typically arises on formal termination in connection with a superior proposal.
Go-Shop Provisions as an Alternative
A go-shop clause flips the script on exclusivity. Instead of prohibiting all solicitation from signing, a go-shop gives the seller a defined window, usually 30 to 60 days, to actively shop the deal and invite competing bids. Once the window closes, the agreement converts to a standard no-shop.
Go-shops show up most often when the seller hasn’t run a full auction before signing. If a single buyer approached the company directly and negotiated without competitive bidding, the board may insist on a go-shop to satisfy its obligation to seek the best available price. Private equity buyers tend to agree to the structure more readily than strategic acquirers, in part because it gives the board procedural cover while the buyer locks up the deal early.
The trade-off shows up in the breakup fee. Deals with go-shops often use a two-tier fee: a reduced termination fee, often around 50 to 60 percent of the full amount, if a competing bid emerges during the go-shop period, and the full fee if a competing bid surfaces after the no-shop kicks in. The discount reflects the fact that the buyer agreed to let the seller shop the deal, so penalizing the seller at full price for finding a better offer during the shopping window would undercut the whole point.
When the No-Shop Starts and Ends
No-shop restrictions typically take effect when the letter of intent is signed, giving the buyer a quiet window to begin due diligence. The exclusivity period at the letter-of-intent stage usually runs 30 to 60 days, with extensions by mutual written consent common.
If the parties move to a definitive merger agreement, the clause is restated and often tightened with more detailed procedural requirements around the fiduciary out, matching rights, and notifications. The no-shop then lasts until the deal closes or the agreement is formally terminated. If a specified end date passes without closing or extension, the restrictions expire automatically and the seller can re-engage with the market. Buyers who expect a long regulatory review should negotiate the end date carefully. A tight deadline hands the seller a free walk-away option if the antitrust clock runs out.
What Happens If the Seller Breaches the No-Shop
Breaching a no-shop is not simply a matter of paying the termination fee and moving on. Courts have made clear the fee is not automatically the buyer’s exclusive remedy. In Genuine Parts Co. v. Essendant, the Delaware Court of Chancery held that accepting a termination fee did not waive the buyer’s right to sue for breach of contract, because the fee was only designated as the exclusive remedy when the seller terminated in proper compliance with the no-shop’s conditions. A termination that grew out of a material breach didn’t qualify.
Available remedies depend on the jurisdiction and the agreement’s language. Courts may grant a temporary injunction blocking the seller from closing with a rival while the breach is litigated, which gives the original buyer leverage even if the injunction is short-lived. On damages, the majority rule in jurisdictions like New York and California limits recovery to reliance damages, meaning the buyer’s actual out-of-pocket costs from the failed negotiations. Delaware and a growing number of other jurisdictions allow expectation damages, giving the buyer the full benefit of its bargain. The gap between those two measures can be enormous: reliance damages might cover a few million in advisory fees, while expectation damages could reflect the entire profit the buyer expected from the acquisition.
Smart drafters address this upfront by specifying remedies for breach directly in the agreement. The contract can designate the termination fee as the sole remedy, cap damages at a specific amount, or expressly preserve the right to seek equitable relief. Leaving the question ambiguous invites expensive litigation on top of a deal that already fell apart.
