WWL says

Thomas Masterman receives glowing praise as being “pragmatic and cerebral while also having a deep sectoral knowledge", particularly in areas such as mass media and telecoms.

Peers and clients say: 

“He has been great on various important M&A transactions.”

“Tom is a fantastic lawyer with deep knowledge and experience on a wide range of competition issues.”

“He is able to combine industry knowledge with a top-drawer intellect to solve client problems.”


Tom Masterman is counsel in Allen & Overy’s antitrust group. His practice covers all aspects of competition law across a variety of industries, with particular expertise in the TMT sector, where he has advised on many of the most high-profile transactions in recent years.

His recent merger control experience includes advising: 21st Century Fox on EU merger control and UK public interest aspects of its £27.7 billion takeover bid for Sky, and its subsequent US$71 billion acquisition by The Walt Disney Company; Endemol Shine  Group on worldwide merger control aspects of its sale to Banijay; and Tullett Prebon on the CMA clearance (with remedies) of its £1.6 billion acquisition of rival ICAP.

On the behavioural side, Tom has advised on several of the largest and most notable EC cartel cases, including the FX spot trading, auto-parts, credit defaults and heat stabilisers investigations.

Tom is recognised by Chambers and Partners as demonstrating “high levels of technical expertise, coupled with a commercially minded and pragmatic approach”; and by WWL, which notes that he “combines deep industry knowledge with a top-drawer intellect to solve client problems”.

Allen & Overy's global antitrust and competition practice comprises over 120 specialists operating across APAC, Europe and North America. The practice advises corporate clients and financial institutions on their global antitrust transactions, policies, litigation and regulatory strategies, and regularly acts on some of the highest-profile and most complex cases in the market.
