Sellers and their advisors should be wary of relying on buyer extracontractual earnout promises to do something in the future. Even without an anti-reliance clause, Delaware courts will use the integration clause to bar a seller’s fraud claim against a buyer for any earnout promise the buyer made outside the contract to do something in the future. A recent Delaware Court of Chancery case makes this painfully clear.
There, the sellers sold their medical device company to a large strategic buyer, for $155 million cash, and a maximum earnout of $120 million. The medical device was complicated, and the business required capital to hire many direct medicine sales representatives to teach physicians, medical practices, and hospitals how to use its products. During negotiations, the buyer pitched how they could commercialize the target’s medical devices and would hire 94 direct medicine sales representatives, and had budgetary approval to do so.
However, in the merger agreement, the buyer did not represent that it had budget approval for the hiring of 94 direct medicine sales representatives, nor did it promise to hire them.
After the closing the buyer hired one rep, and the sellers earned about $72.5 million out of a potential $120 million in earnout payments. The sellers sued the buyer, accusing the buyer of extracontractual fraud in promising to hire 94 sales representatives and claiming that there was budgetary approval for the hiring of the sales representatives. The buyer moved to dismiss the fraud claim.
The court noted that there was no anti-reliance clause that would bar all extracontractual fraud claims. Nevertheless, the court held that the integration clause barred a fraud claim for promising to hire sales representatives, because that was a future promise, and to be enforceable would have had to be included in the merger agreement. On the other hand, the court permitted the fraud claim concerning budget authorization, because that was an alleged fraudulent statement of present fact.
The takeaway for sellers negotiating earnouts – don’t rely on extracontractual promises. Make the buyer back up those promises in the acquisition agreement: the sellers should have required the buyer to represent in the merger agreement that it had budget approval for the 94 reps, and to commit to a minimum hiring timeline tied to the earnout period. All too often sellers lose earnout lawsuits because they rely on aspirational buyer written promises to use commercially reasonable efforts, or something equally as ambiguous.
