A fiduciary out clause is a provision in a merger agreement that lets the target company’s board back out of the signed deal when going through with it would conflict with the board’s duty to shareholders. It usually gives the board two options: withdraw its recommendation that shareholders approve the merger, or terminate the agreement outright and accept a competing offer. Because most public companies are incorporated in Delaware, these clauses are drafted and litigated under Delaware law.
What the Clause Lets the Board Do
Every signed merger agreement sits in tension with an ongoing legal reality. The buyer wants certainty the deal will close. The target’s board has a continuing obligation to act in shareholders’ best interests, no matter what it signed last quarter. The fiduciary out resolves that tension by writing an escape valve into the contract itself.1Practical Law. Fiduciary Out
Most clauses grant two separate rights. The first is a change-of-recommendation right: the board can publicly withdraw its endorsement of the deal while the agreement remains in force. The second is a termination right: the board can end the agreement entirely and sign with someone else. Some deals grant only the first. Others grant both. The scope is one of the most heavily negotiated points in any acquisition, because it decides whether the board’s out is a real exit or just a public statement of displeasure.
What Triggers a Fiduciary Out
The clause is not a blank check. The agreement defines, in detail, exactly what counts as grounds for the board to use it.
A Superior Proposal
A competing bid triggers the out only if it meets the agreement’s definition of a “Superior Proposal.” That definition typically requires the competing offer to cover at least a majority of the target’s stock or assets, deliver greater value to shareholders than the existing deal when timing and deal certainty are factored in, and be reasonably likely to close. Cash bids usually have to show committed financing. The board cannot simply prefer a different buyer. The new proposal has to clear a bar both parties agreed to at signing.
An Intervening Event
Many agreements also let the board change its recommendation based on an “intervening event”: a significant development that occurs after signing and was not known or reasonably foreseeable at the time. A breakthrough patent approval, an unexpected regulatory shift that increases the company’s standalone value, or a major change in financial performance can qualify. Agreements usually spell out specific exclusions to prevent the board from invoking the clause for developments that were already visible when the deal was signed.
Notice and Matching Rights
Before the board can actually walk, it has to give the original buyer advance notice identifying the competing bidder and the material terms of the new offer. The original buyer then gets a matching-rights period, commonly three to five business days, to improve its own bid.2Justia. Delaware Code Title 8 Section 146 – Submission of Matters for Stockholder Vote If the competing bidder revises its offer in response, the clock typically resets for a shorter second round. The mechanism gives the first buyer a genuine last shot while letting shareholders capture the benefit of an escalating price.
What It Costs to Use It
Walking away from a signed merger agreement is expensive. Nearly every fiduciary out is paired with a termination fee, usually called a breakup fee, that the target pays to the original buyer when the board invokes the clause.
A study of transactions through 2024 found target termination fees ranging from 0.2% to 6.0% of deal value, with a mean of 2.4% and a median of 2.6%.3Houlihan Lokey. 2024 Transaction Termination Fee Study On a billion-dollar deal, the median works out to roughly $24 million to $26 million. Smaller deals tend to carry higher percentages because the buyer’s fixed negotiation and diligence costs eat a larger share of the overall value. Payment is usually due when the termination notice goes out or when the target signs with the new bidder, depending on how the agreement is drafted. Some deals also add a separate expense-reimbursement provision covering the buyer’s legal, advisory, and due diligence costs.
The fee can be tiered. In deals that include a “go-shop” provision allowing the target to actively solicit competing bids for a short window after signing, any bidder identified during that window usually qualifies as an “excluded party.” If the target later terminates in favor of one of those bidders, the breakup fee commonly drops to roughly one-third to two-thirds of the standard amount. The reasoning is that a buyer who agreed to a go-shop already accepted the risk of competition and shouldn’t be paid as if the target broke a strict no-shop promise.
How Surrounding Deal Terms Shape the Out
A fiduciary out doesn’t operate alone. It sits inside a package of deal-protection terms, and two of them determine how much the out is actually worth.
The No-Shop and Its Window-Shop Exception
A no-shop clause bars the target from soliciting competing bids, negotiating with other potential buyers, or opening its books to rival bidders after signing. The restriction covers the company, its officers, its directors, and its financial advisors. A window-shop exception carves out room for the board to respond when a third party approaches without being invited. If the board determines, after consulting its advisors, that the unsolicited approach could reasonably lead to a better deal, it can engage and share confidential information.4Practical Law. The Window-shop Exception in Openlane Deals The target can open the door; it just can’t go knocking.
Force-the-Vote Clauses
Some agreements require the target to put the merger to a shareholder vote even after the board has withdrawn its recommendation. Delaware law expressly allows this: a corporation can contractually agree to submit a matter to shareholders regardless of whether the board still considers it advisable.2Justia. Delaware Code Title 8 Section 146 – Submission of Matters for Stockholder Vote For a buyer, a force-the-vote clause preserves a chance that shareholders will approve the deal anyway. For the target, it blunts the fiduciary out. If the board changes its recommendation but shareholders vote yes, the merger still proceeds. How this provision is negotiated often decides whether the out has real force.
Why the Clause Has to Exist
Fiduciary outs are near-universal in public company mergers because Delaware courts have made clear that boards cannot contractually surrender their duties to shareholders.
The 2003 Omnicare decision is the reason the clause is effectively mandatory. In that case, a target board signed a merger agreement with no effective fiduciary out and combined it with shareholder voting agreements that guaranteed approval. The Delaware Supreme Court struck down the arrangement, holding that deal protections without an effective fiduciary out were “both preclusive and coercive” and therefore invalid.5FindLaw. Omnicare Inc v NCS Healthcare Inc A board cannot disable itself from exercising its fiduciary obligations at the moment those obligations matter most: when a superior offer arrives.
The underlying duty comes from the 1986 Revlon decision. Once a board decides to sell the company or enters a change-of-control transaction, its obligation shifts to maximizing the value shareholders receive.6Justia. Revlon Inc v MacAndrews and Forbes Holdings A formal auction isn’t required in every case, but the board cannot ignore credible competing offers or accept a lower price for reasons that benefit management rather than shareholders. The fiduciary out is the mechanism that lets a board honor Revlon duties after it has already signed.
What Becomes Public When the Board Uses It
Invoking a fiduciary out triggers immediate SEC disclosure. Both signing and terminating a merger agreement require the target to file a Form 8-K within four business days of the event; if the event falls on a weekend or federal holiday, the clock starts the next business day.7U.S. Securities and Exchange Commission. Form 8-K
A change of recommendation also ripples through the proxy process. If the company has already filed a proxy statement recommending that shareholders approve the merger, pulling that recommendation counts as a material revision. Revised proxy materials have to be filed with the SEC and clearly marked to show what changed.8eCFR. 17 CFR 240.14a-6 – Filing Requirements If the revision is fundamental enough to alter the substance of what shareholders are voting on, the SEC’s ten-calendar-day review period before the proxy can be distributed restarts. The practical result is that a board’s decision to invoke a fiduciary out becomes public almost at once, and the timeline for everything that follows compresses hard.
