Antitrust M&A

Weil has an impressive track record of obtaining antitrust clearance in “bet-the-company” mergers, acquisitions and joint ventures.

Notable Representations, Key Contacts

Weil offers global solutions to our clients’ Antitrust/Competition transactional needs with one of the largest, most diversified and well-respected practices in the world. Trusted with many of the largest mergers in the last two decades, we bring to bear a combination of law firm and public-sector experience.

We coordinate multi-jurisdictional filings to assure maximum chances for swift approval and protect our clients against the adverse effects of mergers through effective advocacy before various governmental agencies.

Recognized as a “powerhouse merger clearance team” by Chambers USA, Weil helps clients structure transactions and business practices that minimize antitrust concerns. We provide integrated solutions to competition related business issues by collaborating with lawyers in various practices including Mergers & Acquisitions, Intellectual Property, Restructuring and Public Company Advisory Group.

Former Government Officials

Many of our partners were high-level government antitrust officials and formerly headed divisions at the Federal Trade Commission, where they were responsible for the review of mergers and acquisitions in numerous industries, including pharmaceuticals, medical devices, biotechnology, aerospace, defense, industrial, scientific, technology, retail, hospitals and consumer products.

This background provides the group with significant experience and insight into the merger review process and the substantive analysis that may be applied to transactions in these and other industries.

Shaping U.S. Antitrust Policy

Our team has consistently been at the forefront of U.S. antitrust policy and procedure, and while serving in important government positions, assisted in developing the government’s approach to merger enforcement, influenced the body of Hart-Scott-Rodino rulings, and designed the government’s merger discovery process.

International Competition

Our Antitrust/Competition international network helps multinational companies meet the challenges of globalization, including increased scrutiny of mergers and acquisitions by regulatory agencies throughout the world. We have achieved significant success before major authorities and courts in the U.S., Europe, and many other jurisdictions.

Weil has the international reach and experience to handle multinational reviews of mergers and acquisitions with competition lawyers in the United States and European Union. In countries where Weil does not have offices, we have developed strong and effective collaborative relationships with the best local competition law firms.
