Signing vs Closing Conditions

The Structural Choice: Simultaneous vs. Split Exchange

In the landscape of private M&A, the decision to decouple signing from closing is rarely a matter of preference. It is typically a necessity dictated by the regulatory environment or the capital structure of the target. A simultaneous signing and closing, often referred to as a 'one-step' deal, is the cleaner execution path as it eliminates the interim period risk. However, the increasing complexity of international investment screening, such as the UK National Security and Investment Act or CFIUS in the United States, mandates a split structure where the agreement is signed but completion is deferred until government approval is obtained. This gap, which can range from several weeks to many months, creates a period of vulnerability for both the buy-side and sell-side that must be managed through contractual safeguards.

Anatomy of Conditions Precedent

Conditions Precedent, or CPs, are the specific requirements that must be satisfied or waived before the parties are legally obligated to close the transaction. Sophisticated sellers will always push for a 'short-form' set of conditions, ideally limited to mandatory regulatory approvals and the absence of any legal injunction preventing the sale. From the buyer's perspective, there is often a desire to include more subjective conditions, such as the continued employment of key management or the successful completion of a specific customer contract renewal. However, making a deal conditional on such internal matters effectively turns the purchase agreement into an option, which is rarely acceptable to institutional sellers. The negotiation of CPs is therefore a zero-sum game of certainty; the more conditions a buyer adds, the less certain the seller is that the deal will actually reach completion.

The Role and Reality of the MAC Clause

The Material Adverse Change clause acts as the primary safety net for a buyer between signing and closing. It is designed to provide an exit if a catastrophic event occurs that fundamentally alters the long-term economic value of the target. In English law practice, the threshold for invoking a MAC is notoriously high. It generally requires a change that is not only significant in magnitude but also durable in duration, rather than a temporary fluctuation in earnings. Because of this high bar, the MAC clause is seldom used to actually terminate an agreement. Instead, its presence serves as a critical mechanism for price renegotiation. If a target’s performance deteriorates significantly during the interim period, the buyer may threaten to litigate the MAC clause as a tactic to force the seller back to the table for a valuation adjustment.

Interim Covenants and Operational Control

During the interval between signing and closing, the target company enters a state of operational limbo. The buyer has committed to the purchase but does not yet own the assets, while the seller remains the legal owner but lacks the long-term incentive to reinvest in the business. To protect the value of the acquisition, the purchase agreement will include interim covenants. These are negative pledges that prevent the seller from taking extraordinary actions, such as issuing new debt, granting large salary increases, or entering into significant capital expenditure, without the buyer's prior consent. These covenants must be calibrated with extreme care. If they are too restrictive, they may lead to the degradation of the business before the buyer takes control; if they are too permissive, the buyer may inherit an entity that looks very different from the one they valued during due diligence.

The Significance of the Bring-Down

The final hurdle in a split signing structure is the 'bring-down' of representations and warranties. This is the requirement that the statements made by the seller at the time of signing remain true and accurate as of the closing date. This creates a potential conflict if an event occurs that is outside of the seller’s control but renders a representation untrue. Most sophisticated agreements distinguish between a 'general' bring-down and a 'fundamental' bring-down. While a minor breach of a secondary warranty might not allow the buyer to walk away, a breach of a fundamental warranty, such as the seller’s legal title to the shares, almost always provides a termination right. The interplay between the bring-down, the disclosure schedule, and the pre-closing covenants forms the technical foundation of risk allocation in the final stages of the deal cycle.
