Thyssenkrupp Marine Systems (TKMS), Germany's largest naval shipbuilder, made a strong debut on the Frankfurt Stock Exchange Monday, with shares trading significantly above initial expectations. The stock opened at €60 per share, far surpassing analyst forecasts of approximately €36, and surged as much as 23% to €73.90 during early trading before settling around €89 by midday. The robust performance reflects investor enthusiasm for defense companies amid historically high military spending globally.

The initial public offering represents a key milestone in Thyssenkrupp's corporate restructuring, with the parent company spinning off its naval division to create an independent entity. Under the separation terms, Thyssenkrupp shareholders received one TKMS share for every 20 Thyssenkrupp shares they held as of October 17. Despite the spin-off, Thyssenkrupp retains a 51% majority stake in TKMS through a new holding company, maintaining strategic control while allowing the marine systems business to access capital markets directly.

TKMS brings substantial operational scale to public markets, employing approximately 9,000 people and boasting an order backlog of €18.6 billion. The company claims world leadership in non-nuclear powered submarines while also constructing frigates and corvettes. Chief Executive Oliver Burkhard described the move to independence as "a strong signal for maritime security" and positioned TKMS as "the maritime powerhouse in Europe." The company operates multiple facilities across Germany including Kiel, Wismar, Hamburg, Bremen, and Emden, plus an international presence in Itajaí, Brazil.

The market debut received additional visibility through temporary inclusion in Germany's MDAX index for the trading day, a move by index provider Stoxx to ensure investor tracking clarity. Combined with Thyssenkrupp's remaining shares, shareholders saw their holdings increase by approximately 14% following the separation. The successful listing comes amid favorable conditions for defense contractors, with TKMS benefiting from both its market-leading position and substantial existing contract portfolio that provides revenue visibility for years to come.
