Shannon Eagan


I help my clients navigate litigation and disputes involving securities, corporate governance and complex commercial issues.

Shannon Eagan represents corporations and individuals in complex disputes and litigation, internal corporate investigations and Securities and Exchange Commission investigations and actions. Shannon successfully defended a drug development company and its officers and directors in a victory that validated how many life science companies disclose clinical data to the public before the Ninth Circuit Court of Appeals. She also served on the trial team for the first defendant to obtain an acquittal in a stock-options backdating prosecution. Shannon has handled a wide variety of other complex litigation matters, including securities litigation, high-stakes licensing disputes, commercial contract litigation, corporate governance disputes and merger litigation. Her clients have included companies in the life sciences, hardware, software, semiconductor, food and public utility industries. Shannon serves as Northern California head of Cooley's business litigation practice.
