Compass Lexecon

Compass Lexecon traces its origins to Lexecon Inc., founded in 1977 by Richard Posner, William Landes, and Andrew Rosenfield. The modern firm was formed in 2008 through the combination of Compass and Lexecon and operates as a subsidiary of FTI Consulting.

The firm advises law firms, corporations, government entities, and other clients on antitrust and competition economics, financial economics, international arbitration, litigation, regulatory proceedings, and public policy. Its work combines empirical analysis, economic modelling, and expert testimony.

Compass Lexecon is particularly strong in competition matters: merger review, antitrust investigations, and litigation. It also has established practices in damages and valuation, securities and financial markets, intellectual property, energy, and arbitration, with economists frequently supporting high-stakes cases as expert witnesses.
