What is Material Adverse Change (MAC)?

A significant negative event that harms a company's value, operations, or future prospects, like major financial losses or legal troubles. Often called a Material Adverse Effect (MAE), it’s a key term in contracts like mergers or loans.

Why it Matters?

  • Protects buyers or lenders from unexpected risks.

  • Allows them to back out or renegotiate if something big goes wrong before the deal closes.

How it Works?

  • Contracts define what counts as a MAC (e.g., not general economic slumps).

  • The change must be serious and long-lasting to trigger the clause.

  • Disputes over MACs can end up in court, where judges decide if the change was bad enough.

Example

If a company being bought loses its main product due to a new law, the buyer might use the MAC clause to cancel the deal.
