Luxembourg-based OCSiAl, a global leader in the industrial synthesis of graphene nanotubes, announces the appointment of Antigone Loudiadis as a director.
An investment entity owned by Loudiadis made a substantial investment in OCSiAl at the end of 2025. This investment followed an investment earlier that year by a Luxembourg “club” of investors.
Partner at Goldman Sachs International
Ms. Loudiadis founded and led Rothesay Life, one of the UK’s leading pension insurers. Prior to the establishment of Rothesay Life, she was a partner at Goldman Sachs International and cohead of its European Investment Banking Division. Over the course of her 30-year career as a senior financial executive, she led complex structured and M&A transactions and managed senior relationships with governments and multinational institutions.
“I am very excited to be joining OCSiAl,” said Loudiadis. “It’s cutting-edge deep tech that takes established industries—like tyres and coatings—to a new level. But it also goes hand in hand with the next step in the development of EVs, data centres, AI, robotics and aerospace.”
“I am delighted to have Addy on the board. She brings a rare combination of deep capital markets expertise and firsthand experience in building and governing large, capital-intensive businesses,” said Peter Cuneo, Chairman of the OCSiAl Board. “As OCSiAl accelerates its industrial scale-up and prepares for significantly larger long-term investments, her perspective will be invaluable in shaping our capital strategy, strengthening governance, and engaging with a broader base of global investors.”
As advanced materials increasingly take on strategic importance alongside energy and capital, OCSiAl’s current phase of industrial scale-up places the company at the centre of this shift.
