Global Competition Review recognises Cornerstone Research in the 2025 edition of the GCR 100.
Global Competition Review (GCR) again named Cornerstone Research one of the world’s outstanding global economic consultancies. Describing the firm as ‘[s]trategically well-positioned,’ GCR highlights the work of the firm’s almost 250 competition economists who work on antitrust litigation and investigations across the United States, the United Kingdom and Europe.
GCR notes that ‘[o]ver the past two years, Cornerstone Research has significantly enhanced its offering through the strategic hire of individuals with valuable government regulatory experience.’ Experienced senior hires to the antitrust and competition and merger investigations practices in 2024 include Ari Gerstle (Washington, DC), Norbert Maier (Brussels) and Andrew Swan (London).
Cornerstone Research works mainly on high-profile antitrust litigation and government investigations into anticompetitive conduct and proposed mergers.
Led by practice coheads Celeste Saravia (San Francisco), Kostis Hatzitaskos (Chicago) and Liam Colley (London), Cornerstone Research provided support in several recent high-profile matters. GCR noted several, including:
- In re HIV Antitrust Litigation
- Value Drug Company v. Takeda Pharmaceuticals U.S.A. Inc. et al.
- United States of America et al. v. JetBlue Airways Corporation and Spirit Airlines Inc.
- Amgen Inc.’s Acquisition of Horizon Therapeutics plc
Compiled annually, the GCR 100 provides a quantitative and qualitative analysis of the law firms and economic consultancies doing the most important antitrust work around the world.
The 2025 GCR 100 assessment formally covers experience and personnel during the period 31 May 2023 through 31 May 2024. More recent developments may also be considered.
