Fiduciary Out

A provision in a signed M&A agreement allowing the target's board to change its recommendation or accept a competing superior offer when legally required by fiduciary duties to shareholders. Common in public company deals; occasionally relevant for private companies with outside investors and board-level fiduciary obligations. Without a fiduciary out, a board recommending a deal it knows is inferior could be personally liable to shareholders.

Full Definition

A fiduciary out (also called a fiduciary exception or fiduciary duty exception) is a provision in a merger agreement that allows the target company's board of directors to terminate the signed agreement and pursue a competing offer if the board determines that doing so is required by its fiduciary duties to shareholders. The fiduciary out preserves the board's ability to respond to a superior proposal that arrives after signing, without automatically subjecting the company to liability for breach of contract.

The tension it resolves: When a public company signs a merger agreement, it typically agrees to a no-shop provision — prohibiting solicitation of competing offers. But a board that has signed away its right to consider all offers may be in tension with its fiduciary duties to shareholders: if a better deal appears, can the board be legally required to ignore it? The fiduciary out resolves this by allowing the board to consider genuinely superior proposals without breaching the agreement — subject to specific procedural requirements and payment of a termination fee.

Mechanics: A typical fiduciary out requires: (1) receipt of an unsolicited proposal from a third party that the board reasonably determines to be a "Superior Proposal" (generally defined as more favorable to shareholders than the signed deal); (2) the board providing the signed buyer a specified notice period (typically 4–5 business days) and the buyer a matching right; (3) the buyer failing to match or improve its offer within the notice period; and (4) the board formally withdrawing its recommendation and terminating the agreement — upon which the termination fee becomes payable.

Matching rights: The right-to-match provisions give the original buyer the opportunity to counter a superior proposal. Multiple matching rounds in practice can extend the process — courts have generally upheld matching rights even through multiple iterations. The original buyer, having already performed due diligence, often has an informational advantage in deciding whether to match.

Private company context: In private M&A, fiduciary outs are less common because boards have more discretion and there is no public shareholder constituency to protect through formal procedures. Private deal agreements may include no-shop provisions without fiduciary outs, relying instead on the board's general fiduciary duties under applicable state law as the backstop.

Seller vs. Buyer Perspective

If you're selling

Negotiate a meaningful fiduciary out with objective criteria for what constitutes a "Superior Proposal." A fiduciary out that requires the competing offer to exceed the original deal by a large percentage may effectively be no out at all in a market where competitive offers come in at modest premiums. The termination fee (breakup fee) is the cost of using the fiduciary out — ensure it's sized so that a genuinely superior offer is financially viable after paying the fee.

If you're buying

The fiduciary out is the sword hanging over your deal from signing to close — a superior offer can terminate your agreement and give your exclusivity to a competitor. Design the deal terms to minimize this risk: a well-sized termination fee makes using the fiduciary out economically meaningful, match rights give you a window to improve your bid, and a tight closing timeline reduces the window during which a competing offer can emerge. The best protection against a fiduciary out being exercised is a deal that closes quickly.

Real-World Example

A public company signs a merger agreement at $28/share with a 3% breakup fee and a fiduciary out permitting the board to consider Superior Proposals. Thirty days post-signing, an unsolicited offer arrives at $31/share. The board determines this is a Superior Proposal and notifies the signed buyer, triggering a 5-business-day match period. The signed buyer improves its offer to $30/share — not matching the competing offer. The board declares the competing offer still superior; the signed buyer declines to improve further. The board terminates the agreement, pays the $18M breakup fee, and signs with the competing buyer at $31/share — netting shareholders $3M less the breakup fee, still a better outcome.

Why It Matters & Common Pitfalls

  • !Fiduciary out definitions can be too narrow to be useful. A 'Superior Proposal' defined as one that exceeds the existing deal by 15% or more effectively eliminates the fiduciary out in most practical scenarios. Negotiate a reasonable definition — typically one that is more favorable to shareholders in the board's good faith judgment.
  • !Notice periods and matching rights can become protracted. If the original buyer has unlimited matching opportunities, the fiduciary out process can run through multiple rounds, giving the seller the worst of both worlds: prolonged uncertainty and a buyer who incrementally improves rather than providing certainty. Limit matching rights to 1–2 rounds with defined timeframes.
  • !Fiduciary outs do not provide unlimited freedom. The board still owes duties to the original buyer: it must provide the required notices, honor the matching period, and pay the termination fee. Courts have held boards liable for failing to follow the procedural requirements of the fiduciary out — the exception has conditions that must be met.
  • !Private company boards have fewer formal obligations but still face liability. In private transactions, boards may lack the formal fiduciary out procedures of public company deals. Directors who approve a transaction that clearly undermines shareholder value — even without formal fiduciary out machinery — may still face derivative claims. Get legal advice on board duties in any transaction where better alternatives appear to exist.

Frequently Asked Questions

What is a fiduciary out in M&A?
A fiduciary out allows a target company's board to change its recommendation or accept a superior competing offer despite a signed deal — when doing so is required by board members' fiduciary duties to shareholders.
When does a fiduciary out apply to private companies?
Fiduciary outs are primarily a public-company concept. In private companies, they become relevant when there's a board with outside investors, minority shareholders with voting rights, or institutional governance requirements that create board-level fiduciary obligations beyond just the controlling shareholder.
