Nikon SLM Reshuffles Management: CEO O'Leary to Join Supervisory Board in Q4; Two Executives Become Co-Presidents

On November 4, 2026, Nanjixiong learned that Nikon SLM Solutions is changing its management structure. Current CEO Sam O'Leary will move to the Supervisory Board in the fourth quarter of 2026. Chief Financial and Administrative Officer Jan-Niklas Thielmann and Chief Technology and Engineering Officer Simone Castellani will become co-presidents and join the Management Board.



The two co-presidents will oversee day-to-day operations, while O'Leary will continue to contribute to strategy from the Supervisory Board and support customers and partners. Hamid Zarringhalam, CEO and General Manager of Nikon Advanced Manufacturing and chair of the Supervisory Board, will continue to oversee the metal additive-manufacturing business as a business unit. The company said the transition emphasizes continuity and is built on a stable business foundation.

Nikon SLM also confirmed that its next-generation metal additive-manufacturing system, MACHX, will be launched during Formnext 2026, about two weeks before the exhibition opens. O'Leary said the company is stable and fully integrated into Nikon, and that the timing of the transition prepares it for the upcoming technology launch.

Nanjixiong's view A major metal AM manufacturer is completing a leadership transition before a trade show, placing day-to-day operations under leaders from finance and technology. Competition is shifting from machine specifications alone toward production delivery, cost, and organizational efficiency.
