The Weil team in Brussels regularly plays a key role in handling our clients’ landmark M&A, antitrust, FSR, and FDI matters before the European Commission, EU Member States’ regulators, and other agencies globally.
The multinational and multilingual team’s stand-out reputation is built on proven excellence in advising clients on multi-jurisdictional, often highly-complex transactions, antitrust investigations, and litigation matters.
The team has unparalleled expertise in European merger control, backed by a track record of successfully navigating some of the most complex cases that have been decided by the European Commission to-date. For example, Brussels office attorneys have been involved in the majority of all cases in which the European Commission approved a transaction with remedies at Phase 1 in 2023. They have also acted for the notifying party in what is the largest merger control matter, by deal value, that the European Commission has cleared with Phase 2 remedies in the past several years.
Weil’s antitrust group is ranked in Global Competition Review’s “GCR 100 2025,” the publication’s list of the top 100 law firms for antitrust worldwide, among GCR’s 2024 and 2025 Global Elite and in the top ten of GCR’s 2024 Global Elite: Mergers “thanks to rapidly growing competition teams in Brussels.”
Global Competition Review has recognized Weil’s success as global antitrust counsel to Microsoft Corporation in the completion of its $68.7 billion acquisition of Activision Blizzard Inc. with three awards at the publication’s annual GCR Awards 2024. The transaction was selected for “Matter of the Year,” a global category that encompasses all forms of antitrust, as well as “Merger Control Matter of the Year: Americas” and “Merger Control Matter of the Year: Europe,” which honor deals that featured “creative, strategic and innovative competition work for a client on a landmark merger control matter” across respective jurisdictions.
The Brussels office played a pivotal role in helping Weil win Law360’s 2024 Technology Group of the Year award, which highlighted the Firm’s antitrust representation of Microsoft in its $10 billion investment in OpenAI. The team has also been nominated, and was highly commended, for the Competition and Regulatory Team of the Year Award at The Lawyer Awards 2024.
