Closing Conditions
Closing conditions are requirements that must be met before a deal can close — regulatory approvals, rep accuracy, no material adverse change. Failure to satisfy can delay or kill deals.
Full Definition
Closing conditions (or conditions to closing) are the contractual prerequisites that must be satisfied or waived before either party is obligated to close an acquisition. Until all conditions are met, neither party is required to complete the transaction — the conditions are the final checkpoint between a signed agreement and a done deal.
Categories of closing conditions: Closing conditions fall into several categories. Representations and warranties bring-down: The parties' representations and warranties made at signing must remain accurate as of closing — if material facts have changed, the affected party may have grounds to not close. Regulatory and government approvals: Required approvals (antitrust clearances, CFIUS, industry regulators) must be obtained. Third-party consents: Specified material contract consents (customer consents, landlord consents, lender consents for debt assumption) must be received. No material adverse effect (MAE): No event that constitutes a Material Adverse Effect on the target's business may have occurred between signing and closing. Deliveries: The parties must have exchanged specified documents at closing — officer's certificates, board resolutions, payoff letters, employment agreements.
The MAE condition: The Material Adverse Effect condition is the most litigated closing condition in M&A. If the target's business significantly deteriorates between signing and closing, the buyer may attempt to invoke the MAE condition to terminate. Courts (particularly Delaware) have historically set a very high bar for what constitutes a legally sufficient MAE — routine business downturns, industry-wide events, and even significant revenue declines have been found insufficient to constitute an MAE. Buyers relying on the MAE condition to exit a deal face an uphill legal battle in most cases.
Conditions vs. covenants: Closing conditions are distinct from pre-closing covenants (obligations the parties undertake between signing and closing, such as operating the business in the ordinary course). A breach of a covenant can create liability but doesn't automatically prevent closing — the distinction is important when the breach is minor.
Mutual vs. unilateral conditions: Most conditions are mutual (apply to both parties) but some are one-sided. A financing condition benefits only the buyer — if the buyer can't get financing, they can exit (subject to the reverse breakup fee). Sellers rarely agree to buyer-only conditions without extracting a meaningful reverse breakup fee as compensation.
Seller vs. Buyer Perspective
Negotiate closing conditions to be specific, objective, and limited. Vague conditions give buyers exit opportunities — "material consents shall have been obtained" is harder to enforce than listing the specific consents required. Push back on broad MAE definitions and ensure carve-outs adequately exclude industry-wide downturns, macro events, and the announcement of the deal itself from what can constitute an MAE. The fewer conditions to closing, the more deal certainty you have.
Closing conditions are your contractual safety valve. Use them to address the risks you've identified in diligence: specific consents from material customers, regulatory approvals with hard deadlines, the absence of specific identified risks. But don't overload the agreement with conditions you can't realistically monitor or that will be waived routinely — excessive conditions create closing friction without adding protection. Focus conditions on the deal-breaking risks, not every conceivable concern.
Real-World Example
A healthcare services acquisition has five closing conditions: (1) HSR clearance obtained, (2) CMS enrollment for the target's primary billing number transferred, (3) three major customer contracts consented to change of control, (4) the key physician's employment agreement executed, and (5) representations and warranties accurate at closing. All five are met by the target date, and the deal closes on schedule. If any one condition had failed, the buyer would have had the contractual right to not close — or to negotiate a resolution.
Why It Matters & Common Pitfalls
- !Broad MAE conditions rarely allow buyers to exit. Delaware courts have held that only dramatic, sustained deterioration constitutes a legally cognizable MAE — not quarter-to-quarter performance shortfalls or industry headwinds. Buyers who sign deals and then try to invoke MAE to exit face substantial litigation risk. Don't rely on MAE as your exit mechanism for ordinary business risk.
- !Unsigned consents at closing create post-close problems. If a consent is listed as a condition but the parties waive it to close on time, the contract assignment is invalid until consent is obtained post-close. Plan for this contingency with a transition services arrangement and a specific post-close timeline for the remaining consent.
- !Regulatory conditions need outside dates. Include an outside date — a date by which required regulatory approvals must be obtained or the deal automatically terminates — to prevent open-ended delays. Regulatory conditions without outside dates can strand parties in limbo for months.
- !Financing conditions are the seller's enemy. A buyer-only financing condition means the seller can't close the deal (and must wait) if the buyer's financing falls through. If you agree to a financing condition, extract a meaningful reverse breakup fee — not just expense reimbursement — as the price of giving the buyer that flexibility.

Hart-Scott-Rodino (HSR) Act
A federal law requiring advance notification to the FTC and DOJ for M&A transactions above certain size thresholds — triggering a mandatory waiting period for antitrust review before closing.
Representations & Warranties
Statements of fact the seller makes about the business in the purchase agreement — covering everything from financial accuracy to contract validity — with indemnification remedies if any prove false.
