On May 27, 2026, Chancellor Kathaleen McCormick of the Delaware Court of Chancery issued a memorandum opinion in Le Clair v. KnowBe4, Inc., C.A. No. 2024-1143-KSJM, granting defendants’ motions to dismiss all claims arising from Vista Equity Partners’ $4.6 billion acquisition of KnowBe4, Inc. The decision is notable for its treatment of two key issues: (1) the standard for pleading the existence of a stockholder control group, and (2) the cleansing effect of an informed, uncoerced stockholder vote under Corwin v. KKR Financial Holdings LLC where entire fairness would otherwise apply due to director-level conflicts. 125 A.3d 304 (Del. 2015). The opinion reinforces the importance of robust procedural protections — including a fully empowered special committee and a majority-of-the-minority vote — in similar M&A transactions involving director-level conflicts.
