Mark C. Molumphy, a partner at Cotchett, Pitre & McCarthy, LLP, is a native of the Bay Area, born in San Mateo, California.

Mark has served as lead trial counsel in many of America’s most prominent cases and, during his extensive career, recovered over one billion dollars for his clients.  Today, Mark is considered one the nation’s most accomplished trial attorneys in securities, corporate governance, and data security and privacy.

In 2020, Mark’s string of historic results earned him recognition on the Daily Journal’s distinguished list of the Top 100 Attorneys in California. In 2021 and 2022, Mark was included in Super Lawyer’s list of the Top 100 Lawyers in Northern California, America’s Top 100 High Stakes Litigators, The National Trial Lawyers Top 100, and Irish Legal 100.  Mark was also named to Lawdragon’s 500 Leading Plaintiff Financial Lawyers for 2020, 2021 and 2022. In 2022, Mark also received the prestigious ranking in Securities for California from Chambers.

Mark currently serves as co-lead counsel in several noteworthy class actions, litigating issues of first impression relating to newly-enacted data privacy and security statutes.  In the Apple Device Performance Litigation, after years of litigation, Mark successfully negotiated a $310 million settlement – the largest all-cash recovery in a computer intrusion case in history – on behalf of a class of approximately 100 million iPhone users.

Mark also serves as co-lead counsel in In re Zoom Video Communications, Inc. Privacy Litigation, representing a nationwide class of over 100 million Zoom users, alleging that Zoom failed to encrypt Zoom meetings, improperly shared user information, and left many exposed to “Zoombombing” by unauthorized third parties in violation of privacy and unfair competition laws. In August 2021, the parties announced a settlement requiring Zoom to pay $85 million in cash compensation and implement comprehensive reforms to its business.  

Mark has led many of the most prominent securities class actions. In 2023 alone, Mark helped negotiate settlements of behalf of shareholders of Eventbrite ($19.25 million) and MicroFocus ($107.5 million). Mark negotiated multi-million dollar settlements on behalf of former shareholders of Bay Meadows Race Track, mutual fund shareholders of Janus, and investors purchasing shares in the initial public offerings of Alibaba ($75 million) and LendingClub ($125 million), two of the largest IPO class action settlements in history. Mark served as Lead Counsel in the Freddie Mac preferred shareholder securities litigation, following the government’s historic takeover in 2008, and represented numerous cities and counties in California related to their investment losses in Lehman Brothers, Washington Mutual and AIG, amongst others. 

Mark has also led some of the largest shareholder derivative actions in the nation, including as co-lead counsel for the Trustee of the Fire Victims Trust, assigned PG&E’s rights to pursue action against its own officers and directors relating to the 2017 North Bay Fires and 2018 Camp Fire. The case recently settled for $117 million, one of the largest direct recoveries ever against company directors. Mark previously worked on the PG&E shareholder derivative action arising from the San Bruno gas pipeline explosion, resulting in a $90 million recovery, one of the largest derivative Settlements in U.S. history, as well as extensive reforms to PG&E’s underground gas transmission systems to protect customer safety.

Mark was honored as a finalist for the Consumer Attorneys of California Attorney of the Year, based on his work as lead counsel for a nationwide class of investors in Medical Capital, a medical receivable company which operated a massive Ponzi scheme that targeted elderly investors.  After convincing the federal court to reject a paltry settlement negotiated by the SEC, Mark obtained $173 million in settlements on the eve of trial, which remains the largest Ponzi scheme recovery in California history.

Mark has extensive experience in complex actions based on cutting edge legal issues, and cases  ranging from consumer products to elderly financial abuse to environmental protection, including In re Wells Fargo & Co. Derivative Litigation (fictitious accounts and sales practices) and Smith v. Merrill Lynch (Orange County Bond Litigation).  

Over almost three decades of practice, Mark’s work has resulted in the recovery of hundreds of millions of dollars and the implementation of novel governance reforms for public and private companies alike, as well as their shareholders.
