Vilius BernatonisTGS Baltic

TGS Baltic is a leading name for capital markets work, as is evidenced by it recently acting for Lithuania’s Ministry of Finance on its issuance of €2bn worth of Eurobonds in connection with the Covid 19 pandemic. Other prominent areas of activity included acquisition finance and property finance transactions, as well as fintech-related matters. Žygimantas Stankevičius formerly worked as head of legal at Luminor (Lithuania’s largest bank), making him well-placed to handle regulatory work. He jointly leads the team with Vidmantas Drizga, who is an expert in capital markets transactions, derivatives and insolvencies. In addition to acting for major players in the domestic market, the firm’s client base also consists of international names such as Credit Suisse and Revolut. Vilius Bernatonis and associate partner Mantas Gofmanas are also recommended.

Lithuania > Dispute resolution

TGS Baltic demonstrates particularly strong capabilities in disputes connected with the energy sector, as was evidenced when it recently represented the Ministry of Energy in a landmark case against Veolia over alleged corruption and competition issues. Managing partner Vilius Bernatonis, who acted on that particular dispute, is also an expert in insurance and tax matters. The practice is led by Marius Brasiūnas, who is also highly experienced in the energy sector, and has additional strengths handling retail and banking issues. Senior partner Valentinas Mikelėnas joined Ellex.
