TKMS Dangles Climate Tech to Nab Canadian Submarine Deal as Defence Sector Loses Its Luster

ThyssenKrupp Marine Systems invests in Alberta carbon capture to offset Canadian submarine bid, but stock downgraded amid defence sector slump and FCAS collapse.

ThyssenKrupp Marine Systems is pulling a strategic lever that might seem odd for a submarine builder: investing in carbon capture. The German defence group has signed two letters of intent in the Canadian province of Alberta, teaming up with Heirloom Carbon Technologies and thyssenkrupp Calvion to build direct air capture plants using a limestone-based process. No investment figure has been disclosed, but the calculus is clear — Canada demands that any foreign defence contract above C$100 million be fully offset by reinvestment in the local economy.

TKMS is chasing a multibillion-dollar order to supply the Royal Canadian Navy with a new submarine fleet. The competition is fierce. South Korea’s Hanwha Ocean has already been qualified as a bidder and is dangling the prospect of delivering four boats by 2035. TKMS, backed by Germany and Norway, is offering up to twelve submarines — but the first delivery would not come until 2036 at the earliest. By ploughing money into Alberta’s climate technology, TKMS hopes to sweeten its bid into an irresistible package that compensates for the longer timeline.

Yet even as management pursues that high-stakes gambit, the broader defence sector is losing momentum. Kepler Cheuvreux has downgraded TKMS shares to “Reduce” and slashed its price target to €66.00. Morgan Stanley added to the gloom by cutting its rating on European defence stocks to “Equal Weight,” pulling Rheinmetall and Renk down alongside TKMS. The triggering event was the collapse of the Franco-German FCAS next-generation fighter jet programme, a political failure that underscores the fragmentation of Europe’s defence industry. While TKMS builds submarines, not fighters, the news poisoned sentiment for the entire German defence cohort.

The stock has been caught in the downdraft. Shares currently trade at €71.20, having lost more than 7% over the past week. The gap to the January high of €102.90 is widening daily, and the relative strength index has fallen to 36, signalling heavy downward momentum. Annualised volatility over the last 30 days stands at nearly 48%. On one recent session, the stock did manage a 0.56% gain to €72.30, trimming the weekly decline to around 6%, but that brief respite did little to alter the technical picture.

The €66.00 target from Kepler now looms as the next waypoint. Without a fresh catalyst — such as a firm contract from Ottawa or a broader turnaround in defence sector sentiment — the shares lack the fuel for a sustainable recovery. The letters of intent with Heirloom and Calvion are not binding; firm investment commitments are still missing. If TKMS can convert this climate pivot into a winning bid for the Canadian submarine programme, however, a major re-rating could follow. Until then, the stock remains caught between a bold strategic play and a sector that has suddenly lost its shine.
