ThyssenKrupp Marine Systems goes public - ThyssenKrupp Marine Systems Begins Trading After Successful Spin-Off
ThyssenKrupp Marine Systems (TKMS) has begun trading on the stock exchange today, following a successful spin-off from its home company. Shareholders approved the move at an extraordinary general meeting in early August, marking a significant change for the world leader in non-nuclear submarines and builder of frigates and corvettes.
The former HDW surface shipbuilding division, now operating as German Naval Yards, was spun off and will now operate independently. The shipyard, part of Thyssenkrupp since 2005, has a rich history tracing back to its founding in Kiel as HDW in 1838.
The spin-off, which saw shareholders receive one TKMS share for every 20 Thyssenkrupp shares they held, was completed on Friday. ThyssenKrupp AG retains a strategic majority stake of 51% in TKMS, with the remaining 49% distributed to existing Thyssenkrupp shareholders. The initial public offering (IPO) took place on October 20, 2025. TKMS employs around 8,300 people.
The spin-off and IPO of TKMS mark a new chapter for the company, allowing it to operate independently while still maintaining a strategic link with ThyssenKrupp AG. The move is expected to provide TKMS with greater flexibility and agility in the global maritime defence market.
