Key Takeaways
- • Delaware Supreme Court affirmed dismissal of stockholder challenges to advance notice bylaws at The AES Corporation and Owens Corning on April 29, 2026, ruling that plaintiffs' claims were unripe because no actual nomination dispute existed.
- • Advance notice bylaws are subject to "twice-tested" review—first for legal authorization, then for equitable fairness—but equitable challenges require a genuine, concrete controversy, not hypothetical deterrence arguments.
- • The Court rejected claims that broad "acting in concert" definitions, exclusive compliance requirements, and extensive disclosure obligations created self-executing or economically coercive effects sufficient to establish ripeness without a real-world nomination context.
- • Delaware courts preserved flexibility for future challenges: stockholders may establish ripeness without a rejected nomination on a different factual record, and as-applied challenges remain available even after facial challenge periods expire.
- • For boards, the decision provides latitude to update advance notice bylaws in response to SEC's 2021 universal proxy rule without immediate equitable scrutiny absent a real nomination dispute; for activists, the ruling underscores the necessity of pleading concrete facts demonstrating present controversy.
Summary
On April 29, 2026, the Delaware Supreme Court, sitting en banc, issued a consolidated opinion in In re The AES Corporation and Owens Corning that affirmed the Court of Chancery's dismissal of two stockholder actions challenging advance notice bylaws adopted by both companies in 2023. The cases arose in response to the SEC's 2021 universal proxy rule, which requires dissident stockholders' nominees to comply with state law and company governing documents—including valid advance notice bylaws—to be included on universal proxy cards. Failure to comply permits exclusion from proxy materials, creating significant incentives for companies to adopt or strengthen advance notice provisions.
The plaintiffs in both cases sought declaratory and injunctive relief, alleging that the bylaw packages were defensive and entrenched. The challenged provisions shared common features: each made compliance with advance notice procedures the exclusive means for stockholder director nominations, authorized the presiding officer to disregard noncompliant nominations, adopted broad "acting in concert" definitions including "daisy-chain" provisions extending acting-in-concert status to third parties, and required extensive ownership and relationship disclosures from proposing stockholders. After the Delaware Supreme Court's 2024 decision in Kellner v. AIM ImmunoTech established a demanding standard for facial invalidity claims, plaintiffs amended their complaints to focus on equitable relief based on alleged deterrent effects on board nomination efforts. However, neither plaintiff alleged intent to run a proxy contest or identified any stockholder currently deterred from nominating directors.
The Delaware Supreme Court's analysis centered on the ripeness doctrine. The Court held that although advance notice bylaws face "twice-tested" scrutiny—first for legal authorization and second for equitable fairness—equitable review requires a ripe controversy. Here, because no stockholder had attempted or threatened a nomination implicating the challenged provisions, the Court found the disputes remained hypothetical. The Court rejected the plaintiffs' argument that features like exclusive compliance requirements, broad acting-in-concert definitions, and extensive disclosures created a self-executing or economically coercive chilling effect before any contest began. Instead, the Court characterized these provisions as procedural and disclosure obligations that impose no inherent deterrence absent actual application.
The Court's decision was carefully cabined. It did not establish a categorical rule requiring a rejected nomination before equitable relief becomes available, nor did it decide whether specific provisions such as broad acting-in-concert concepts or extensive disclosure requirements would survive enforcement in an actual contest. The Court also rejected plaintiffs' policy argument that deferring equitable review invited aggressive bylaws to escape challenge, citing its Moelis & Co v. West Palm Beach Firefighters' Pension Fund decision confirming availability of as-applied challenges even after facial challenge periods expire.
For institutional investors and boards, the ruling clarifies that updating advance notice bylaws to reflect evolving federal proxy frameworks will not automatically trigger equitable scrutiny without a concrete nomination dispute. For activist investors and dissident stockholders evaluating potential proxy contests, the decision underscores the critical importance of pleading specific facts demonstrating present controversy—such as actual or imminent nomination efforts or identifiable deterrence affecting specific stockholders—before seeking equitable relief in Delaware courts.
