Merger Control

We advise many of the world's most sophisticated businesses on their merger control strategies.

Our purpose is to create value for our clients by supporting them on winning regulatory approval of private mergers and acquisitions, public takeovers, joint ventures, cooperation or distribution agreements and disposals.

Our merger control team is an integral part of Allen & Overy’s Corporate practice which, in the last five years, has advised on more than 1,360 M&A deals worth over GBP730 billion, according to Mergermarket. Our clients can be confident that we will provide the highest quality of strategic merger control advice.

Having acted on some of the most pioneering transactions in recent years, we are expert in advising on complex, multi-jurisdictional mergers involving in-depth regulatory scrutiny and remedy negotiation. The practice is renowned for its experience in guiding multinational companies through complex and sensitive phase I and phase II merger control cases, before the European Commission, Department of Justice, Federal Trade Commission and other (inter)national regulators. We have extensive experience working on multi-jurisdictional merger control strategies and filings, with a cross-border network of specialists further supplemented by a wide network of local referral firms.

Through our work on ground-breaking cases we are able to draw on our knowledge of novel strategies and complex issues at the forefront of antitrust policy to deliver value to our clients and minimise the risk in any merger control execution process.
