The buyer is proposing a performance-based earnout tied to gross margin, but they are taking over our operations. How do we structure the purchase agreement to prevent them from undermining our margins through their own corporate overhead or supply chain decisions?

Question

A margin-based earnout is dangerous because post-close operational decisions are out of your hands. If the buyer consolidates supply chains, shifts vendors, or allocates corporate overhead to your business unit, your gross margin can disappear on paper. To protect your earnout, you must negotiate strict operational and accounting covenants in the purchase agreement.

First, define how gross margin is calculated with absolute specificity. Insist that the calculation uses your historical accounting methodologies and excludes any allocated parent company overhead, corporate management fees, or shared services costs.

Second, secure veto rights over operational changes that directly impact your margins. For example, include a covenant that prevents the buyer from changing your pricing structure, altering client contracts, or switching core suppliers without your written consent. If they insist on making these changes, the purchase agreement should state that your earnout targets will be adjusted downward accordingly.

Third, tie the earnout to operational Rocks that you control, rather than purely financial metrics. Track these metrics transparently. If the buyer fails to support the business as agreed, or if they fail to resource the seats on your Accountability Chart, the earnout should accelerate and become fully payable. Protecting your payout requires keeping operational control over the variables that drive the math.
