Delaware Court of Chancery Addresses Benefit-of-the-Bargain Damages in Busted Deals and Who Can Seek Them
On October 31, 2023, in Crispo v. Musk, Chancellor Kathaleen St. J. McCormick of the Delaware Court of Chancery issued a decision addressing an important question that arises in mergers and acquisitions: if one of the parties (usually the buyer) refuses to close the transaction, can the jilted company (usually the target company) obtain “benefit-of-the-bargain” damages (including the lost premium that would have gone to stockholders)? At least based on the circumstances before it, the court answered that question in the negative, indicating that only stockholders who are third-party beneficiaries of the agreement, not the corporation, would be entitled to such damages. We expect the decision to engender significant discussion and impact merger agreement drafting.
