Securities, M&A & Corporate Governance Litigation

Given the frequent interplay between things such as corporate-control transactions, public offerings, activist shareholders, the use of complex derivatives and other financial instruments, bad news impacting stock performance, regulatory inquiries and investigations, and insurance coverage, strategic and tactical litigation decisions can have a wide-ranging impact on the success of a given transaction, as well as on companies, their boards, senior management, and advisors....Read more

Winston Wins Ninth Circuit Reversal and Class Certification in Swimmers’ Antitrust Case, Securing a Global-Impact Settlement with World Aquatics

Winston represents a class of professional swimmers alleging World Aquatics (WA) violated antitrust laws by blocking their participation in the competing  International Swimming League. After WA won summary judgment, Winston successfully appealed, arguing the court applied improper antitrust standards and wrongly denied certification of a damages class. In September 2024, the Ninth Circuit reversed both rulings, reviving all claims and issuing a landmark ruling on the possible application of the per se rule or quick look review to sports-associations rules. Am Law awarded Winston “Litigator of the Week” Runner-Up recognition for the win. In November 2024, the Ninth Circuit denied rehearing. In April 2025, the district court certified a damages class....Read more

A Team Co-led by Winston & Strawn Negotiates a Landmark Antitrust Class Action Settlement with the NCAA and Its Power 5 Conferences

Secured, with co-counsel, final approval of an historic settlement of over US$2.75B in back-damages for current and former college-athletes and a new revenue-sharing model allowing schools to share future earnings with athletes.
