TL;DR: A no-shop clause prevents the target company in an M&A transaction from soliciting, encouraging, or engaging with competing acquisition proposals during the pendency of a signed deal. It is the buyer's primary tool for protecting its investment of time, money, and reputational capital in pursuing the transaction, but it stands in direct tension with the target board's fiduciary duty to maximize shareholder value. The negotiation of no-shop provisions is where deal protection meets fiduciary obligation, producing some of the most carefully calibrated language in any acquisition agreement. The key battlegrounds are the scope of the restriction, the availability of a "fiduciary out" permitting the board to consider unsolicited superior proposals, the definition of what qualifies as a "superior proposal," the buyer's right to match competing offers, and the break-up fee that compensates the buyer if the target exercises its fiduciary out. Draft too broadly, and the provision may be unenforceable as an unreasonable restraint on the board's fiduciary duties. Draft too narrowly, and the buyer has paid a premium for exclusivity it does not actually have.

‍

What Is a No-Shop Clause?

A no-shop clause (also called an "exclusivity provision" or "non-solicitation covenant") is a provision in a merger or acquisition agreement that prohibits the target company and its directors, officers, employees, agents, and advisors from soliciting, initiating, or knowingly encouraging competing acquisition proposals from third parties. At its core, the no-shop is a promise by the target: "We have chosen you as our deal partner, and we will not go looking for someone else while this agreement is in effect."

No-shop clauses typically contain several components working together: (1) the affirmative prohibition on solicitation; (2) a restriction on providing non-public information to potential competing bidders; (3) a requirement to cease and terminate any existing discussions or negotiations with third parties; (4) a notification obligation requiring the target to inform the buyer of any unsolicited approaches; and (5) exceptions that permit the target board to consider unsolicited superior proposals when its fiduciary duties require it to do so.

The no-shop should be distinguished from a "no-talk" provision, which goes further by prohibiting the target from even engaging in discussions with unsolicited bidders. Pure no-talk provisions without fiduciary outs are disfavored and potentially unenforceable in Delaware because they may prevent the target board from fulfilling its duty to remain informed about value-maximizing alternatives. The no-shop should also be distinguished from a "go-shop" provision, which affirmatively permits the target to solicit competing bids for a limited period after signing, typically 20 to 45 days, before a no-shop restriction takes effect.

Why It Matters

Buyer's Investment Protection: Acquiring companies invest significant resources in due diligence, deal structuring, financing arrangements, and regulatory preparation. The no-shop protects this investment by preventing the target from using the buyer's signed deal as a "stalking horse" to attract higher bids from competitors who benefit from the buyer's price discovery without incurring the same costs.
Fiduciary Duty Tension: The target board has a fiduciary duty to act in the best interests of its shareholders. In the Revlon context (when a sale of control is inevitable), this duty requires the board to seek the best price reasonably available. A no-shop clause that prevents the board from even considering a clearly superior offer may violate this duty. The fiduciary out exists to resolve this tension, but its scope and mechanics are intensely negotiated.
Deal Certainty and Financing: Lenders and financing sources evaluate deal certainty when committing to acquisition financing. A strong no-shop provision increases the buyer's certainty of closing, which can improve financing terms, lower commitment fees, and reduce the risk of financing markets deteriorating before closing.
Strategic Signaling: The structure of the no-shop sends signals to the market. A deal with a pure no-shop (no go-shop period, narrow fiduciary out, high break-up fee) signals that the target board is highly committed to the transaction. A deal with a go-shop period signals that the target board wanted to test the market post-signing, which may invite competing bids or may confirm the announced deal's pricing.
Shareholder Litigation Risk: No-shop provisions are among the most frequently challenged deal terms in shareholder litigation. Shareholders may argue that an overly restrictive no-shop, combined with a high break-up fee and limited matching rights, effectively "locked up" the deal and prevented the board from fulfilling its fiduciary duties. The target board must be prepared to defend the reasonableness of the no-shop as part of its overall deal protection package.

Key Elements of a Well-Drafted No-Shop Clause

Scope of Prohibited Conduct: Define precisely what the target and its representatives are prohibited from doing. At minimum, the prohibition should cover soliciting, initiating, knowingly encouraging, or knowingly facilitating any inquiry, proposal, or offer that constitutes or could reasonably be expected to lead to an acquisition proposal. Specify whether the restriction applies only to the target company or also extends to its subsidiaries, directors, officers, employees, financial advisors, legal counsel, and other representatives.
Definition of "Acquisition Proposal": Define the types of transactions covered by the no-shop. The standard definition covers any proposal or offer for a merger, consolidation, business combination, tender offer, exchange offer, recapitalization, or acquisition of a specified percentage (typically 15-20% or more) of the target's assets or equity. A broader definition captures any transaction that would result in a third party acquiring a material interest in the target; a narrower definition covers only transactions involving a majority of the target's assets or voting securities.
Cessation of Existing Discussions: Require the target to immediately cease and terminate any existing discussions or negotiations with third parties regarding potential acquisition proposals, and to request the return or destruction of any confidential information previously provided to such parties. Without this provision, the target could continue pre-signing negotiations with competing bidders under the cover of claiming they were "existing" rather than "new" discussions.
Fiduciary Out: Permit the target board to engage with an unsolicited acquisition proposal if the board determines, after consultation with its financial advisors and outside legal counsel, that the proposal constitutes or could reasonably be expected to lead to a "superior proposal" and that failure to engage would be inconsistent with the board's fiduciary duties. The fiduciary out is the safety valve that prevents the no-shop from conflicting with the board's legal obligations. Without it, the provision may be unenforceable in Delaware and other jurisdictions that impose Revlon duties.
Superior Proposal Definition: Define what constitutes a "superior proposal" that triggers the fiduciary out. The standard definition requires a bona fide written acquisition proposal (not merely an expression of interest) for all or substantially all of the target's assets or equity, on terms that the board determines (after consultation with its advisors) are more favorable to the target's shareholders than the pending transaction, taking into account all relevant factors including certainty of closing, financing, regulatory risk, and timing.
Matching Rights: Grant the buyer the right to match or improve its offer before the target board can terminate the agreement to accept a superior proposal. The typical matching right requires the target to provide the buyer with written notice of the superior proposal (including its material terms and the identity of the bidder), followed by a negotiation period (typically 3-5 business days for the initial match and 2-3 business days for subsequent matches) during which the buyer may revise its offer. If the buyer matches, the target must continue with the original transaction.
Notification Obligations: Require the target to promptly notify the buyer of any unsolicited acquisition proposal, indication of interest, or inquiry, including the identity of the party making the approach and the material terms of any proposal. Some agreements require the target to provide copies of all written materials received. The notification obligation allows the buyer to monitor competitive activity and prepare its matching strategy.
Break-Up Fee: While technically a separate provision, the break-up fee (or termination fee) is the primary enforcement mechanism for the no-shop. If the target board exercises its fiduciary out to accept a superior proposal, the target pays the buyer a termination fee, typically 2-4% of enterprise value in public company deals. The break-up fee compensates the buyer for its deal costs and serves as a deterrent against casual deal-shopping by the target.

Market Data

According to the 2023 ABA Public Target Deal Points Study, no-shop provisions appeared in 100% of one-step merger agreements and 98% of two-step tender offer deals. Fiduciary outs were included in approximately 99% of no-shop provisions, confirming that pure no-shops without any fiduciary exception are essentially extinct in public company M&A.
Go-shop provisions appeared in approximately 28% of public company deals in 2023, according to Practical Law data. Go-shop usage was significantly higher in private equity transactions (approximately 50%) than in strategic deals (approximately 15%), reflecting PE buyers' willingness to accept go-shops in exchange for deal certainty on price.
The median go-shop period was 30 days in 2023, with a range of 20-45 days. The median "go-shop termination fee" (the reduced break-up fee payable during the go-shop window) was 1.5% of equity value, compared to the standard termination fee of 3.1% applicable after the go-shop period expired.
The median break-up fee in public company M&A was 3.1% of equity value in 2023, according to the Practical Law M&A database. Break-up fees ranged from 1.5% to 5.5%, with fees above 4% increasingly subject to judicial scrutiny in Delaware as potentially preclusive of competing bids.
Matching rights appeared in approximately 85% of no-shop provisions in 2023. The median initial matching period was four business days, with subsequent matching periods of three business days. Approximately 20% of deals included an unlimited number of matching rounds; the remaining 80% permitted two to three matching rounds.
Delaware courts have struck down no-shop provisions on only rare occasions, but have been willing to scrutinize the overall deal protection package under the Unocal/enhanced scrutiny standard. In In re Smurfit-Stone Container Corp. Shareholder Litigation (2011), the court found that the combination of a no-shop, matching rights, and a 3.5% break-up fee was reasonable and did not preclude competing bids.

Common Contract Types

Public Company Merger Agreements: No-shop provisions are universal in public company M&A, where they interact with fiduciary duties, shareholder approval requirements, and SEC disclosure obligations.
Private Company Acquisition Agreements: No-shop provisions are less common in private company deals (where the seller's fiduciary duty framework is different), but exclusivity agreements during the negotiation period serve a similar function.
Letters of Intent and Term Sheets: Pre-signing exclusivity provisions in LOIs and term sheets are the most common form of no-shop in private company transactions, typically binding for 30-90 days while the buyer conducts due diligence and negotiates definitive agreements.
Real Estate Purchase Agreements: Exclusivity provisions in commercial real estate transactions prevent the seller from marketing the property to other buyers during the due diligence and closing period.
Joint Venture Agreements: Exclusivity provisions may restrict JV partners from pursuing competing ventures or soliciting competing partners in the same industry or geography.
Franchise and Distribution Agreements: Exclusivity provisions in these agreements restrict the grantor from appointing competing franchisees or distributors in a defined territory, serving a function analogous to the no-shop in the M&A context.

Negotiation Playbook

Key Drafting Notes

Calibrate the fiduciary out to the transaction context: In a public company deal, a fiduciary out is effectively mandatory under Delaware law (and most other corporate law regimes). In a private company deal with a controlling shareholder, the fiduciary out may be unnecessary because the controlling shareholder can simply consent to the transaction. Tailor the fiduciary out to the governance structure of the target.
Define "Acquisition Proposal" with the right threshold: A 15% threshold captures minority investments that could presage a full acquisition, giving the buyer broader protection. A 50% threshold covers only change-of-control transactions, giving the target more flexibility to pursue minority investments or joint ventures during the exclusivity period. The right threshold depends on the buyer's competitive concerns and the target's ongoing business needs.
Coordinate the break-up fee with the matching right: The break-up fee and matching right work together: the fee deters competing bidders (who must top the buyer's offer by at least the amount of the fee to provide equivalent value), while the matching right gives the buyer a last look before the target can accept a superior proposal. If the fee is too high, it may be deemed preclusive; if the matching right is too generous, it may deter serious competing bids.
Address "don't ask, don't waive" standstills carefully: Some targets enter into confidentiality agreements with potential bidders during pre-signing market checks that include standstill provisions preventing the bidder from making unsolicited proposals. "Don't ask, don't waive" provisions further prohibit the bidder from requesting a waiver of the standstill. Delaware courts have expressed concern that these provisions, when combined with a no-shop, can prevent shareholders from receiving potentially superior offers.
Consider the go-shop as an alternative: If the target has not conducted a pre-signing market check, a go-shop period gives the board a post-signing opportunity to test the market, which can help satisfy fiduciary duty obligations and reduce litigation risk. The go-shop also benefits the buyer by providing market validation of the deal price if no superior offers emerge.

‍

Common Pitfalls

No-shop without fiduciary out in a public deal: A no-shop provision in a public company deal without any fiduciary exception is likely unenforceable under Delaware law and will invite shareholder litigation and judicial scrutiny. Always include a fiduciary out in public company no-shops.
Overly broad "representative" definition: Extending the no-shop restriction to all "agents and representatives" of the target without limitation can create compliance challenges. Individual shareholders (especially in private company deals) may not be bound by the company's covenant, and the target may be unable to control the actions of every person who could be characterized as a "representative." Define the scope clearly and consider whether separate undertakings from key shareholders are needed.
Failing to address inbound inquiries: A no-shop that prohibits only "solicitation" without addressing how the target should handle unsolicited inquiries creates a gray area. Specify that the target may acknowledge receipt of an unsolicited inquiry and inform the third party of the existence of the no-shop restriction, but may not provide substantive responses or non-public information absent the fiduciary out being triggered.
Break-up fee above the Revlon ceiling: Delaware courts have generally upheld break-up fees in the range of 2-4% of equity value but have expressed skepticism about fees exceeding 4-5%. A fee that is so high as to deter any competing bid may be struck down as a preclusive deal protection device. Keep the fee within market range and be prepared to justify it in terms of the buyer's actual costs and the competitive dynamics of the deal.
Ignoring the interaction with shareholder rights plans: If the target has a shareholder rights plan ("poison pill") in place, the no-shop should address whether the target board retains the discretion to redeem the pill to facilitate a superior proposal. A no-shop that prevents the board from redeeming the pill to facilitate a competing bid may be viewed as preclusive when combined with other deal protection devices.

‍

Jurisdiction Notes

United States: Delaware law provides the primary framework for analyzing no-shop provisions in public company M&A. The Revlon line of cases (beginning with Revlon, Inc. v. MacAndrews & Forbes Holdings, Inc., 1986) establishes that when a sale of the company is inevitable, the board's duty shifts from preservation of the corporate entity to maximization of shareholder value. Under this standard, deal protection devices including no-shop clauses, break-up fees, and matching rights are analyzed under the enhanced scrutiny standard of Unocal Corp. v. Mesa Petroleum Co. (1985), which requires the board to demonstrate that the deal protections are reasonable in relation to the threat posed and do not preclude competing bids. The Delaware Court of Chancery has generally upheld no-shop provisions with fiduciary outs, matching rights of three to five business days, and break-up fees of 2-4% as reasonable deal protection. Other states generally follow Delaware's analytical framework, though the specific standards may vary.

United Kingdom: The UK Takeover Code governs deal protection in public company takeovers, and its approach differs markedly from the US. Under Rule 21.2 of the Takeover Code, an offeree company (target) may not enter into a deal protection arrangement (including a no-shop or break-up fee) with an offeror unless the Takeover Panel consents. The Panel will typically permit inducement fees (break-up fees) of up to 1% of the offer value, significantly lower than the 3-4% standard in US deals. The Takeover Panel has also taken a restrictive view of no-shop provisions, requiring that they include appropriate fiduciary outs and not unduly restrict the target board's ability to consider competing offers. For private company transactions, the Takeover Code does not apply, and no-shop provisions are governed by general contract law principles, with wider latitude for parties to negotiate exclusivity arrangements.

Other Jurisdictions: In the EU, the regulation of deal protection devices varies by member state. Germany's Takeover Act (WpUG) does not specifically regulate no-shop provisions, and German practice generally permits broader deal protection than the UK Takeover Code. In France, the AMF (Autorite des Marches Financiers) has taken a restrictive approach to deal protection, and break-up fees are uncommon in French public M&A. In Australia, the Takeover Panel has historically limited break-up fees to 1% of equity value and required that no-shop provisions include meaningful fiduciary outs. In Canada, the practice is closer to the US, with no-shop provisions, matching rights, and break-up fees of 2-4% being standard in public company deals, subject to the board's fiduciary duties under Canadian corporate law.
