He has extensive experience as a corporate lawyer and specializes in the areas of banking, finance and energy, with an emphasis on corporate finance, securities, regulatory work, EPC projects, commercial transactions and real estate.

He and the banking team advised an international investment bank as Tender Advisor to a Voluntary Tender Offer launched by the largest Greek bank to acquire all outstanding stock of another major credit institution, in what was described as a banking mega-deal for Greek standards

Nicholas is a prominent corporate lawyer and litigator and has represented clients such as Heinz, Anheuser Busch, Nielsen, companies in the Mytilineos Group in several high profile transactions and landmark disputes before the higher courts and arbitration boards.

A recent highlight of Nicholas’ track record is the successful representation of Mytilineos Holdings in a bilateral investment treaty dispute against Serbia under the UNCITRAL Arbitration Rules. The dispute related to an investment in state-owned RTB BOR, one of the largest metallurgical and mining complexes for copper extraction and production on a global basis. Moussas & Partners together with other international law firms represented the Greek conglomerate in this landmark case where the Tribunal ordered Serbia to pay to Mytilineos compensation in the area of US$40 million.
