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.
