Rheinmetall stock: why Germany just dealt a major blow to its biggest defense firm

Rheinmetall AG (RHM) shares are slipping on Wednesday – heading toward one of their sharpest single-day declines ever – due to a major blow to the company’s naval defense pipeline.

On Jun. 24, the German Defense Ministry said it is cancelling the “multi-billion-euro” F126 frigate program, which was slated to be the largest naval procurement project for the German Navy since World War II.

Including today’s crash, Rheinmetall stock is down more than 50% versus its year-to-date high.

Here’s why Rheinmetall stock tanked today

Rheinmetall was positioned to take over as the prime contractor for the F126 frigate program.

Management had actively targeted this contract for completion in Q2, expecting it to bring in €12 billion (at least) in order intake.

Analysts from Morgan Stanley estimate the sudden cancellation would force RHM stock to absorb about €2 billion in write-downs.

This is largely due to its recent €1.5 billion buyout of the Naval Vessels Lürssen (NVL) shipyard, a strategic move specifically designed to anchor its execution of the F126 project.

The Defense Ministry cited severe software delays, persistent friction, and projected cost overruns that would have driven the final bill past €18 billion if they continued with the program.

TKMS shares are defying the defense sector sell-off

Instead of continuing with the F126 “super-frigates,” Berlin has pivoted entirely.

On Wednesday, the German government announced plans to purchase eight smaller Meko A-200 frigates from Rheinmetall’s direct competitor, TKMS AG.

While Rheinmetall shares cratered, TSMS stock was seen trading up as much as 14% on Jun. 24, mostly because Berlin pay roughly €6.3 billion for the first four TKMS vessels, with an option for four more at €5.3 billion.

This massive divergence highlights a swift reallocation of capital across EU defense portfolios, as investors aggressively price in the long-term cash flow injection from the revised naval strategy, immediately transforming TKMS into Germany’s premier maritime contractor.

Wall Street remains bullish on RHM shares

The German Defense Ministry’s announcement has exposed a deeper anxiety across the entire EU defense sector, pulling down peers like Hensoldt, Renk, and Saab.

Investors are beginning to realize that aggressive government defense budgets do not automatically translate into locked-in revenues for specific land defense contractors.

Moreover, capital flows are facing fragmentation as Franco-German tank maker KNDS announced plans today for a dual Frankfurt-Paris IPO, creating a new alternative for defense sector investment.

This sudden contract loss exacerbates a tough year for RHM shares, featuring lacklustre revenue conversions and an investor rotation into drone and air defense-focused manufacturers.

Still, Wall Street analysts remain convinced that Rheinmetall AG will recover in the back of 2026, given the consensus rating on the automotive and arms manufacturer sits at “Buy” currently, according to The Wall Street Journal.
