Allen & Overy is one of the premier antitrust and competition practices in the world. Our International Antitrust and EU Group encompasses 80 specialist antitrust lawyers located in 19 jurisdictions in Europe, the US and Asia Pacific and includes many of the leading practitioners in the field.

Antitrust advice is highly business sensitive: cartel activity can result in substantial fines; dominant undertakings can be required to grant rivals access to key assets or change business strategy; mergers can be prohibited or, in some cases, unwound, under merger control regimes now operating in approximately 65 countries and continuing to proliferate; and State aid may have to be repaid.

Competition authorities worldwide have wide-ranging powers of enforcement. In several jurisdictions, including the US and UK, individuals involved in breaches of competition law may be imprisoned as well as individually fined, and in the EU, companies found to have acted anti-competitively may be fined up to ten per cent of their annual worldwide turnover.

We pride ourselves on offering a top-level, client-focused service, with integrated multi-jurisdictional teams providing transaction support on restrictive agreements, abuse of dominance/monopolisation, merger control, State aid and other aspects of EU and US law.
