Material Adverse Change (MAC) Clause
Definition
A contractual provision in acquisition agreements that allows the buyer to withdraw from or renegotiate a transaction if the target company experiences a significant negative event between signing and closing. MAC clauses define what constitutes a material change and typically exclude general market downturns, industry-wide conditions, and changes in law, focusing instead on company-specific deterioration.
