Tyson Redenbarger is a Partner at Cotchett, Pitre & McCarthy LLP practicing in a wide range of civil litigation areas including class actions and complex civil litigation. In 2022, Tyson was listed by the Daily Journal as one of the “Top 40 Under 40” attorneys in California.
In 2026, Tyson served as one of the lead trial counsel in the successful securities fraud case against Elon Musk concerning his 2022 acquisition of Twitter. Following a three-week federal jury trial in San Francisco, the team achieved a rare jury verdict in a Rule 10b-5 case. The jury’s verdict awarded plaintiffs and a class of Twitter investors with damages that are presently estimated to exceed $2.6 billion. While the ultimate damages amount will depend on the class claim process, this verdict will likely be one of the largest securities fraud verdicts ever.
In 2025, Tyson received the California Lawyer Attorney of the Year award from the Daily Journal, in recognition of his work in the Safelite whistleblower litigation. The litigation exposed a long running scheme to overbill insureds across the country. The case resolved for $31 million, the largest individual insurance fraud act recovery in history.
Tyson has also served as lead plaintiffs’ counsel in numerous consumer and securities class actions in both state and federal courts, including serving as part of the litigation team in Boston Retirement Systems v. Uber Technologies, Inc. (N.D. Cal.)—a federal securities case involving claims that Uber issued false and misleading statements concerning its $8.1 billion IPO. In December of 2024, the court approved a $200 million recovery for Uber shareholders—one of the largest settlements ever for such a case. Tyson has also served as an attorney for Lead Counsel in several state securities actions, including In re Eventbrite, Inc. Shareholder Litigation and In re Microfocus International PLC Securities Litigation, representing hundreds of thousands of investors. Tyson also recently served as an attorney for Lead Counsel in In re Apple Inc. Device Performance Litigation (N.D. Cal.), representing millions of iPhone owners across the United States. The District Court recently approved the class settlement of $310 million in that multidistrict litigation. Other cases include breach of fiduciary duty suits (John Trotter (Ret.), Trustee of the PG&E Fire Victim Trust v. Williams et al., which settled for $117 million), consumer privacy suits (In re Zoom Video Communications, Inc. Privacy Litigation, settled for $85 million) and environmental suits, including a pollution suit brought on behalf of the citizens of California against the top ten plastic producers. Tyson also works on derivative shareholder cases, including cases representing shareholders of Wells Fargo, Facebook, Gilead, and We Work.
Prior to joining CPM, Tyson worked for a tenant rights law firm in San Francisco, representing tenants who were wrongfully evicted and tenants living in uninhabitable conditions. Tyson handled several jury and bench trials, including two class action trials where he successfully obtained significant recovery for tenants who were impacted by a delayed condominium conversion.
Representative Matters
Tyson worked extensively on the In Re Apple Device Performance litigation, in which Apple agreed to pay up to $500 million to settle. Tyson was part of the co-lead counsel team that was responsible for plaintiffs’ discovery, including defending class representatives at deposition and coordinating discovery from more than 100 named plaintiffs.
Tyson represented the 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.” The case, In re Zoom Video Communications, Inc. Privacy Litigation, alleged that Zoom violated the privacy of its users and engaged in unfair competition by claiming its services were encrypted when they were not. In August 2021, Zoom agreed to settle the case, paying $85 million in cash compensation and implementing comprehensive reforms to its business.
Tyson has also worked on numerous securities class actions. In 2023, Tyson helped negotiate settlements on behalf of shareholders of Eventbrite ($19.25 million) and MicroFocus ($107.5 million).
Tyson has also contributed to some of the largest shareholder derivative actions in the nation, including serving with 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. That case recently settled for $117 million, one of the largest direct recoveries ever against company directors.
Tyson represented Gilead shareholders in a trial over Gilead’s refusal to produce internal records relating to Gilead’s development and marketing of AIDS drugs and possible anticompetitive conduct. After more than a year of litigation and a full trial, shareholders received a major victory as the Delaware court ordered the corporation to produce the requested records and pay approximately $1.76 million in attorneys’ fees and expenses.
Tyson successfully represented shareholders of Sanovas, Inc. in a shareholder derivative case alleging that Sanovas’s former CEO defrauded the company and stole millions of dollars from its shareholders. Plaintiffs were successful in halting all payments to the former CEO pursuant to his lucrative severance package, and Plaintiffs negotiated significant corporate reforms, including the expansion of the company’s board of directors and the implementation of an independent audit committee.
Tyson represented two tenants in a jury trial involving claims that the tenants were wrongfully evicted. The jury unanimously found that the eviction was wrongful because the owners rented the tenant’s unit on Airbnb instead of living in the unit, which they were legally required to do. The jury awarded the tenants $390,000 in damages.
