You have signed the letter of intent. You might have even signed the merger agreement. The team is celebrating and you are ready to move on to your next challenge. But the money is not in the bank yet.
Between the moment you sign a deal and the moment it closes, a lot can happen. This interim period is where the Material Adverse Change (MAC) clause lives. It is one of the most heavily negotiated sections of any acquisition agreement because it determines who bears the risk of the unknown.
Understanding the Basics
#A Material Adverse Change is a legal provision included in merger and acquisition agreements. It gives the buyer the right to walk away from the deal without penalty if the target company suffers a significant drop in value before the transaction is finalized.
The logic is simple. A buyer agrees to pay a certain price based on the current state of the business. If the business fundamentally breaks before they take ownership, they should not be forced to buy it at the original price.
However, defining what counts as broken is rarely simple.
What Qualifies as Material?
#This is the gray area where disputes happen. For a change to be considered material, it usually needs to meet two criteria.
- Magnitude: The negative impact on the company’s earnings or assets must be significant. A missed sales target for one month likely does not count. Losing your biggest client who represents 40 percent of revenue probably does.
- Duration: The problem needs to be durationally significant. It cannot be a temporary blip. It must be a long term impairment to the earning potential of the company.
Courts have historically set a very high bar for enforcing MAC clauses. They generally view them as a last resort rather than a convenient way for a buyer to back out because they got cold feet.
Differentiating Market Risk vs Company Risk
#Founders need to understand the difference between general market conditions and specific company failures. A MAC clause is designed to protect the buyer from problems specific to your company.
If the entire economy enters a recession, that is usually not a MAC. If the tech sector crashes, that is usually not a MAC. The buyer is assumed to be taking on market risk when they sign the deal.
However, if your specific factory burns down or your specific intellectual property is ruled invalid by a court, that is a company specific issue. That is where the MAC clause becomes dangerous for a founder.
Negotiating Carve-Outs
#When your lawyers review the purchase agreement, they will focus heavily on exceptions. These are often called carve-outs.
You want the definition of a Material Adverse Change to be as narrow as possible. You want to explicitly state that the buyer cannot walk away due to:
- Changes in the general economy
- Changes in your specific industry
- War or acts of terrorism
- Pandemics or public health crises
- Failure to meet internal projections (unless caused by an underlying material issue)
The goal is to shift the risk of general world events onto the buyer while accepting that you are responsible for the specific health of the business you built.
Every founder should ask themselves how robust their current operations are. If a single point of failure could permanently cripple the business during the closing period, you are holding a significant amount of risk until the wire transfer hits.
