What this risk is, and why it matters
Interim-period risk is the exposure that something materially bad about the target comes to light, or happens, after you have signed but before you complete. For a senior executive, the dilemma is acute: you are committed, yet the basis of the deal may have shifted. Whether you can walk away, renegotiate price, or are forced to complete depends almost entirely on the conditions, interim covenants and material-adverse-change provisions negotiated before anyone knew the problem existed.
Legal and regulatory framework
This is a contractual risk interpreted under the governing law of the agreement. Courts, particularly in common-law jurisdictions, construe material-adverse-change and material-adverse-effect clauses narrowly, setting a high bar for a buyer to walk away, and distinguish company-specific from market-wide events. Conditions precedent and bring-down warranties also govern the position. The framework is the contract and the case law interpreting MAC clauses, which is why precise drafting at signing is decisive.
Typical scenarios and impact
Scenarios range from minor developments absorbed without changing terms, to renegotiated price or remedies, to attempts to terminate that succeed or fail depending on the MAC drafting and the facts. Because MAC thresholds are high, buyers often cannot exit and must complete a deal whose economics have deteriorated, absorbing losses that can reach a meaningful share of value. Litigation over whether a MAC was triggered is expensive, public and uncertain in outcome.
Mitigation framework and when to engage an expert
Negotiate clear conditions, interim operating covenants and a MAC clause whose scope reflects the risks that matter, and require the seller to notify adverse developments. Plan in advance how price-adjustment, remedy or walk-away rights would operate. Engage deal counsel to draft these provisions and to advise if an adverse fact emerges. The leverage to deal with bad news during the interim period is created at signing, through drafting, not improvised once the problem appears.
