Law360 Profiles Simpson Thacher as a 2025 Competition Practice Group of the Year
Simpson Thacher was named a Competition Practice Group of the Year by Law360, recognizing the Firm’s exceptional work across a broad spectrum of antitrust matters. The profile highlighted the team’s role in guiding clients through some of the most complex and closely watched disputes of the year—including helping JPMorgan Chase put an end to long‑running litigation over alleged Libor manipulation and securing a major win for Mattress Firm in the FTC’s challenge to its $5 billion acquisition by Tempur Sealy. Peter Guryan, Sara Razi and John Terzaken, Global Co-Chairs of the Firm’s Antitrust and Trade Regulation Practice, reflected on the team’s standout year. Sara noted that the Mattress Firm decision was precedent‑setting, as the court rejected the FTC’s market‑definition theory central to its challenge. John emphasized the team’s banner year for securing dismissals, highlighting the breadth of cutting‑edge antitrust issues the group handled. Peter added that the team continues to excel in navigating high‑profile mergers through regulatory scrutiny and has been successful “in avoiding a challenge, or a settlement or resolution, and in many cases, having deals cleared outright.”
