What Are Closing Conditions?
M&A deals sign and close on different days because approvals and logistics take time, and closing conditions govern what must happen during that gap. The sign-to-close period runs a few weeks for a simple private deal but can stretch beyond a year for transactions requiring extensive antitrust review. Until every condition is satisfied or waived, neither party is required to complete the purchase.
Conditions are drafted as mutual or one-sided. Mutual conditions, like receiving required regulatory clearances, must be met before either party is obligated. One-sided conditions protect a single party, such as the buyer's right to refuse closing if the seller's reps are inaccurate. Agreements also set an outside date, sometimes called a long-stop date, after which either party may terminate if the deal still has not closed.
The Standard Conditions in a Deal
Regulatory conditions usually top the list. US deals above certain size thresholds require expiration of the Hart-Scott-Rodino waiting period, and cross-border transactions can trigger merger review in multiple jurisdictions. Foreign acquirers of sensitive US businesses may also need CFIUS clearance. Public targets additionally require shareholder approval, and both sides need the absence of any injunction blocking the transaction.
The remaining conditions track the agreement itself. The bring-down condition requires the counterparty's reps to remain accurate at closing, usually measured against a material adverse effect standard rather than word-for-word perfection. Buyers also condition closing on the seller's compliance with interim operating covenants and on the absence of a material adverse change since signing. Financing conditions are rare in public deals but appear in some private transactions.
Why Closing Conditions Matter
Conditions allocate the risk of the world changing between signing and closing. Sellers push for narrow, objective conditions so the buyer cannot manufacture an exit, and in antitrust-heavy deals they may demand hell-or-high-water covenants obligating the buyer to accept divestitures to win clearance. Buyers want conditions broad enough to escape if the business deteriorates or a hidden problem emerges.
High-profile deal litigation almost always centers on conditions, most famously buyers invoking the MAC clause to abandon transactions during downturns, and courts have set a very high bar for those claims. For interviews, be ready to explain why deals take months to close after announcement and what happens when a condition fails before the outside date arrives.
