Gibson, Dunn & Crutcher LLP‘s securities litigation practice frequently handles M&A-related cases, notably in finance, technology, healthcare, energy, accounting and insurance sectors. It is particularly well-respected for its takeover defense work, having handled numerous hostile takeover matters in the US and internationally. Monica Loseman in Denver, Brian Lutz in San Francisco and Craig Varnen in Los Angeles lead the securities litigation practice, in which New York-based Adam Offenhartz is a specialist in M&A litigation, including class action and derivative actions, appraisal cases and earnout disputes. Lutz recently won the dismissal of a class action for Elliott Management arising from the company’s acquisition of Gigamon. Among his recent highlights, Offenhartz acted for Afred E. Mann Trust, a controlling stockholder in medical device company Bioness, in a challenge to its acquisition of Bioventus, which closed successfully after the court denied a dissident directors’ final application for immediate injunctive relief.
