The Delaware Supreme Court has recently made significant rulings that impact mergers and acquisitions (M&A) practices, particularly concerning the treatment of minority shareholders in transactions involving controlling shareholders. The court held that the entire fairness review is applicable to all conflicted controller transactions, emphasizing the protection of minority shareholders' interests. This series of decisions, referred to by some as a 'Delaware Double Whammy,' underscores the Delaware courts' focus on investor protection and rigorous scrutiny of controlling shareholders. These rulings are expected to have far-reaching implications for corporate governance and M&A activities.
