Deal Terms
Last updated
Quick Answer
A significant negative event that fundamentally alters the value or prospects of a company, potentially voiding agreements.
A Material Adverse Change (MAC) clause in venture term sheets or acquisition agreements allows a party to withdraw from a transaction if a significant negative event occurs between signing and closing. What constitutes a MAC is often heavily negotiated — market-wide downturns are typically excluded, while company-specific events (loss of key customers, regulatory actions, fraud) are covered.
In Practice
Between signing a term sheet and closing, a startup loses its largest customer (40% of revenue). The VC invokes the MAC clause and renegotiates terms at a 50% lower valuation.

Why It Matters
MAC clauses create optionality for investors but uncertainty for founders. Understanding what triggers a MAC and negotiating reasonable exclusions is critical for protecting both sides.
VC Beast Take
MAC clauses became the new battleground during COVID-19, with both sides learning expensive lessons about what actually constitutes 'material' and 'adverse.' Smart lawyers now spend more time defining these terms upfront rather than leaving them vague. The pandemic taught everyone that even seemingly bulletproof deals can unravel when MAC provisions are too broad or too narrow.
