Securities Litigation

When corporate transactions or stock price drops trigger headwinds for public companies, our range of services—from board counseling and pre-litigation strategy through trial and appeal—help clients achieve favorable results.

When corporate transactions or stock price drops trigger headwinds for public companies, our range of services—from board counseling and pre-litigation strategy through trial and appeal—help clients achieve favorable results.

Whether sparked by a short-seller attack, a public disclosure, a major corporate transaction or economic turmoil, shareholder lawsuits and allegations of securities law violations or Delaware fiduciary breaches can put a company under an unwelcome spotlight. These claims raise the specter of adverse publicity, burdensome discovery, intrusive demands, and outsize damages claims. O’Melveny’s securities litigators help clients fight back. We work with Fortune 500 companies, directors and officers, underwriters and financial advisors, and corporate acquirers to limit exposure and refocus the public narrative.

With a core team of dozens of securities litigators on both coasts of the United States, our award-winning Securities Litigation Practice brings a decades-long record of pretrial and trial victories for clients in courts across the country, including the United States Supreme Court. We have successfully defended some of the best-known corporations and officers and directors against headline-making securities and fiduciary breach allegations. Our teams are equally experienced at handling the many types of claims that often accompany securities litigation, such as derivative and other fiduciary duty claims, M&A and other transaction-related litigation, and complex commercial disputes.

We also serve as trusted advisors to companies and their boards in the face of business or regulatory challenges. Our securities litigators know that an early and proactive approach is critical to reducing exposure and protecting not only the company, but also its officers, directors and financial advisors. Drawing on our expertise in governance, corporate law, securities law, and litigation, we work with clients to identify the most effective course of action with the clients’ priorities top of mind. Whether providing counseling to directors in a crisis, conducting targeted internal investigations, or developing novel strategies for responding to risks, our team is here to help.

While we always aim to provide our clients a cost-effective resolution, we never shy away from a necessary fight—our lawyers are among a select few who have successfully tried securities-related cases to jury verdict. We also speak our clients’ language. With teams of bilingual attorneys working in Asia and the US, we have deep experience defending China-based US-listed public companies in securities class actions in US courts.
