TKMS Navigates a Two-Front Storm: A $9 Billion Indian Prize and a German Frigate Cost Clash

TKMS closes in on $9B Indian submarine contract, but German F127 frigate cost overruns and F126 halt cloud outlook despite strong backlog.

The German shipbuilder thyssenkrupp Marine Systems (TKMS) is closing in on one of the most consequential contracts in its modern history, even as a public dispute over a separate domestic frigate program threatens to cloud the narrative. Reports indicate that a roughly $9 billion deal with India is nearing completion, a transaction that would place the Kiel-based company at the heart of New Delhi's naval modernization ambitions.

Under the framework of Project 75(I), the agreement calls for the construction of six conventional submarines, developed in partnership with the Indian shipyard Mazagon Dock Shipbuilders. For TKMS, the contract would rank among the largest single orders the company has secured in recent memory, adding fresh momentum to a global pipeline that already includes high-stakes programs in Canada and Europe.

In Ottawa, TKMS has positioned itself as the preferred bidder for a submarine program centered on the Class 212CD design. Chief executive Oliver Burkhard has signaled that, should negotiations conclude successfully, the first vessel could be delivered by 2033. The company has also forged a cooperation agreement with Spain's state-owned Navantia, a move designed to pool construction capacity and jointly pursue future European submarine projects. That partnership alone provided a tangible boost to the share price roughly a month ago, with the stock climbing 9.9 percent in the period since.

A Backlog That Keeps Growing

The internationalization of TKMS's order book has become increasingly visible in its financial disclosures. Including a newly recorded frigate program, the company's total order backlog has swelled to more than €25 billion. Excluding that specific contract, the backlog would have stood at €20.1 billion at the most recent reporting date — a figure that nonetheless underscores how heavily the company now leans on demand beyond Germany's borders.

The operational picture has been equally robust. In its nine-month results for fiscal year 2025/26, released roughly two weeks ago, TKMS raised its EBIT margin guidance to as much as 6.5 percent, up from a previous target of above 6.0 percent. Revenue for the period climbed 19 percent to €1.89 billion, driven primarily by the submarine segment. Management reaffirmed its medium-term objectives through 2027/28, including average annual revenue growth of 10 percent and an adjusted EBIT margin above 7 percent.

Yet the market's response to those numbers has been muted at best. Since the results were published, the shares have retreated 6.5 percent — a sign that investors, while acknowledging the strong operational performance, remain wary of execution risks tied to such ambitious growth targets.

Berlin's Frigate Problem

The more immediate source of friction, however, stems from Berlin. The Federal Ministry of Defence has halted the F126 frigate program due to significant cost overruns, a setback for TKMS as a key player in Germany's domestic naval sector. The separate F127 air-defense frigate program remains unaffected and is still cleared for export, though it awaits approval from the Bundestag's budget committee.

That project has itself become a flashpoint. According to a Spiegel report, the cost of eight F127 frigates has escalated from an original estimate of €26 billion to more than €40 billion — a figure that would put each vessel at over €5 billion. TKMS has publicly pushed back, stating it cannot confirm the €40 billion sum and insisting the figure does not reflect the actual cost shares attributable to shipbuilding itself.

The company, working jointly with Rheinmetall, says its design precisely matches the Bundeswehr's requirements and that a first delivery by 2034 is feasible if the order is placed promptly. Much of the cost pressure, according to reports, stems from the US-made Aegis combat system: eight Aegis sets are expected to cost $11.9 billion, with an additional $3.5 billion for SM-6 and SM-2 guided missiles. Germany would become the first international user of the SPY-6(V1) radar.

The F127 is slated to replace the Sachsen-class frigates from the mid-2030s. For now, only preliminary contracts exist with TKMS and rival NVL, and coalition politicians have voiced doubts about the overall affordability of the program. The stakes for investors are genuinely two-sided: higher program costs could translate into larger revenues for TKMS, but they also raise the risk of political delays or outright cuts.

There is precedent for such recalibration. The halt of the F126 program has been accompanied by plans to procure four MEKO A-200 vessels at a unit price of €1.6 billion — a clear signal that the navy is willing to redirect programs when costs spiral. Germany's naval inspector, Jan Christian Kaack, has meanwhile warned of a growing Russian presence in the Baltic Sea and shortened warning times, a factor that bolsters the fundamental case for continued procurement.

A Stock Caught Between Headwinds

The mixed news flow has produced a volatile trading pattern. On Friday, TKMS shares closed at €90.10, down 1.2 percent on the day, following a session that saw the stock dip as low as €89.70 at one point — a 1.8 percent intraday decline from the prior day's close of €91.30. The weekly performance shows a loss of 3.4 percent, though the 30-day picture remains positive at plus 13 percent. Year-to-date, the shares are still up 36 percent.

The current price sits roughly 17 to 18 percent below the 52-week high of €108.80, reached on August 14. That gap reflects the short-term drag from the frigate cost debate, but it has done little to undermine the longer-term upward trajectory.

The broader German defense sector continues to provide a supportive backdrop. The six largest arms manufacturers — including TKMS, Rheinmetall, KNDS, Hensoldt, Airbus Defence and Space, and Diehl — grew their combined revenue by an average of 17 percent last fiscal year, reaching €35 billion. At the same time, a wave of startups such as Helsing and Quantum Systems, focused on AI-driven drones, is beginning to challenge the established players.

For TKMS, the immediate priorities are clear: seeing the India and Canada negotiations through, advancing the Navantia partnership, and delivering audited annual results for fiscal year 2025/26 in November. Those figures will offer the first real test of whether the surging order intake is translating into improved earnings quality — and whether the company's medium-term targets rest on a foundation solid enough to withstand the political turbulence that seems to accompany every major German defense program.
