Antitrust

Axinn is renowned for representing some of the world’s largest companies in matters of the highest strategic importance. Our track record of success includes leading high-profile civil and criminal litigations and investigations. Orchestrating approximately half a trillion dollars in M&A transactions, we have gained clearances for intensely contested deals, including the largest cash merger in U.S. history, the largest-ever tech deal, and other landmark transactions.

Axinn’s full-service antitrust practice stands among the largest and most experienced. Our team works coast to coast and across borders to deliver integrated counsel on M&A, litigation, and government investigations.

Mergers & Acquisitions

Our reputation as tenacious advocates for strategic transactions is built on our track record of obtaining global clearances for multibillion-dollar deals combining industry rivals. Axinn lawyers are often called upon to serve as lead antitrust counsel and co-counsel in transactions worldwide. Our diverse perspectives and experience make us adept at developing cohesive strategies to address regulators’ concerns head-on and gain approvals in the most challenging jurisdictions.

Antitrust Litigation

Axinn has defended major industry players in some of the most high-profile and complex antitrust litigations and deal reviews in recent history. From private treble-damage class actions and sprawling multidistrict litigations (MDL) to price-fixing, bid-rigging, market allocation, and other antitrust claims, we resolve cases strategically and efficiently. Our experience extends to monopolization disputes, merger trials, criminal defense, and internal investigations. We consistently apply our creativity and bottom-line perspective to achieve exceptional outcomes in matters involving third-party subpoena defenses, leniency applications, antitrust compliance, and government investigations.

Cartels & Investigations

We pride ourselves on handling the two largest price-fixing investigations of the past decade. We’ve represented clients in cartel investigations by major global authorities, including the DOJ, the Australian Competition and Consumer Commission, Brazil’s Administrative Council for Economic Defense, the Canadian Competition Bureau, and the European Commission. Our ranks include former federal prosecutors and leaders from the DOJ Antitrust Division who have overseen criminal investigations, trials, and policy initiatives. Our team takes an integrated approach to handling all aspects of criminal investigations, including compliance programs, internal investigations, government investigations, and criminal proceedings.

Counseling

Our support helps clients navigate challenges that impact their strategic goals and address issues that arise in daily business operations. We offer trusted and practical guidance on a wide range of antitrust issues, including partnerships, pricing, bundling, distribution, trade association activities, information exchanges, and licensing. Clients rely on us to conduct thorough internal investigations and to develop and implement robust antitrust compliance programs. Our client-centric approach empowers them to navigate the most challenging antitrust landscapes with confidence.
