OCSiAl, the Luxembourg-headquartered producer of graphene nanotubes, has expanded its board with the appointment of Antigone Loudiadis as a director.
The move follows a substantial investment made at the end of 2025 by an entity owned by Ms Loudiadis, building on an earlier investment that year from a Luxembourg “club” of investors.
Ms Loudiadis is well known in the UK financial sector, recognised for founding and leading Rothesay Life, one of the UK’s major pension insurance providers. Before establishing the company, she served as a partner at Goldman Sachs International and coheaded its European Investment Banking Division. Her 30‑year career in senior finance has included overseeing complex structured and M&A transactions and managing high‑level relationships with governments and multinational bodies.
“I am very excited to be joining OCSiAl,” she said. “It’s cutting-edge deep tech that takes established industries—like tires and coatings—to a new level. But it also goes hand in hand with the next step in the development of EVs, data centers, AI, robotics and aerospace.”
OCSiAl chairman Peter Cuneo welcomed her appointment, noting: “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.”
The company is currently advancing its industrial scale‑up as advanced materials gain strategic importance globally. OCSiAl manufactures high‑purity graphene nanotubes under the TUBALL™ brand and supports customers through technical centres in Luxembourg, China and Serbia, with a sales and distribution network reaching more than 50 countries and 1,500 manufacturers.
