On June 30, 2016, the Delaware Chancery Court extended the Supreme Court’s holding in Corwin v. KKR Financial Holdings LLC, 125 A.3d 304 (Del. 2015), to two-step mergers under DGCL § 251(h). The Chancery Court concluded that acceptance of a first-step tender offer by a fully informed and uncoerced majority of disinterested stockholders insulates a two-step merger from challenge except on the ground of waste, even if a majority of directors were not disinterested and independent. See In re Volcano Corp. S’holder Litig., C.A. No. 10485-VCMR. In this situation, the business judgment rule is “irrebutable” and dismissal is typically appropriate given the high bar for proving “waste” and the unlikelihood that a majority of informed stockholders would approve such a transaction. In re Volcano is the latest decision underscoring the critical importance of securing an uncoerced and fully informed majority vote of disinterested stockholders if boards wish to benefit from this extremely deferential standard of review.
