Constantinos himself is a dynamic and highly experienced corporate lawyer and is ranked and listed in the major legal directories. He has played a leading role in many landmark transactions, supporting domestic and international clients in realizing their strategic goals, and has a reputation for being relentless in his pursuit of practical solutions to even the most complex challenges. He is recognized by clients and directories alike as a thoroughly modern lawyer, combining acute commercial awareness and strategic thinking with deep technical expertise and outstanding communication, team and leadership skills.

As well as advising on sophisticated financial arrangements and corporate transactions, Constantinos is also a highly skilled arbitrator and accredited mediator.

Areas of expertise

As head of the firm’s M&A practice, Constantinos is an experienced and astute legal adviser and dealmaker. He has supported domestic and international clients from many sectors on a wide range of complex corporate transactions, from privatizations, domestic and cross-border mergers and acquisitions and restructurings to spin offs and disposals, joint ventures and share-purchase agreements.

Ranked in the leading directories, Constantinos is a respected M&A specialist, advising banks, government bodies, corporates and investors – including private equity – on the best and most practical deal structures within Greek and EU law and then helping them to see the deals to completion. He has played a key role in many landmark deals, including the restructuring and privatization of DEPA, the public gas corporation, and has advised on numerous transactions involving companies listed on the Athens stock exchange. Constantinos also acts for private equity funds and multinational corporations in contested public and private M&A acquisitions and advises various private equity funds on MBOs/LBOs, as well as in transactions involving listed companies through the Athens Stock Exchange.

Constantinos’s expertise and experience make him a valued adviser in the most complex and high-profile transactions. He recently advised on the tripartite joint venture between PWC, Qualco and Hoist Finance for the establishment of a Single Technology Platform for the servicing of €9 billion of NPLs, creating the first NPL platform in Greece under the name PQH. He has also worked on several public mergers that have gone before the Hellenic Competition Commission, including the largest attempted banking merger in recent years in Greece, which was cleared on commitments offered by the parties.

A very significant proportion of Constantinos’s work involves cross-border, multi-national or multi-party transactions.
