Recent circuit court decisions reveal a widening split on when forward-looking risk disclosures become materially misleading, while the Third Circuit's abrogation of the Oran-Burlington rule reshapes securities fraud pleading standards. Settlement data from 2026 shows elevated median values and mega-settlements driving aggregate totals, as the Fifth Circuit's Cassava Sciences decision establishes new ground for challenging market efficiency through meme-stock evidence.

In this edition of Dechert’s Securities & Derivative Litigation: Report, we:

  • Analyze two recent circuit court decisions addressing when a forward-looking risk disclosure becomes materially misleading if the warned-of risk has already materialized, which may implicate how your company drafts and updates its own risk disclosures, and the resulting circuit split following the Supreme Court’s dismissal of Facebook, Inc. v. Amalgamated Bank, 604 U.S. 4 (2024), as improvidently granted.
  • Discuss what the Third Circuit’s abrogation of the three-decade-old Oran-Burlington materiality rule in In re Ocugen, Inc. Securities Litigation means for your company’s exposure to securities fraud claims in the Third Circuit, including at the motion to dismiss stage.
