The buyer is insisting on an EBITDA-based earnout to bridge our valuation gap, but we are terrified they will load their corporate overhead and parent-company management fees onto our post-close profit and loss statement. How do we structure the definition of earnout EBITDA to prevent them from artificially suppressing our payouts?

EBITDA-based earnouts are a minefield because the buyer takes operational control post-close and can easily manipulate your net income. They can load the business with corporate allocations, centralized marketing costs, parent-company management fees, and expensive IT systems that destroy your operating margins. If you must accept an earnout to bridge a valuation gap, you must define earnout EBITDA with extreme precision in the purchase agreement. Do not rely on generic accounting definitions. You must negotiate a strict definition of Adjusted EBITDA that excludes all parent-level allocations, corporate overhead, and synergistic expenses. The agreement must state that the business will be operated as a standalone division for the duration of the earnout period. Use your EOS Accountability Chart to define who has spending authority and ensure that your local leadership team retains control over purchasing and hiring decisions. Specify that any shared services provided by the parent company must be billed at pre-negotiated, arm-length rates or excluded entirely from your P&L calculations. You should also demand a floor on operating expenses so the buyer cannot arbitrarily increase spending to suppress your margins. Protecting your earnout requires locking down the operational rules of the game before you sign the definitive agreement.
