Germany’s abrupt cancellation of the six‑ship F126 frigate programme sent shockwaves through the defence sector. The project, which Rheinmetall had negotiated at €15 billion, was set to make the group the lead contractor after a €1.5 billion acquisition of Naval Vessels Lürssen. On the same day, Franco‑German tank maker KNDS unveiled its long‑awaited IPO, heightening investor anxiety.

Rheinmetall shares tumbled 19 % after the announcement, dragging the Stoxx Targeted Defence index into negative territory for 2026 after a rally earlier in the year. The IPO’s valuation band, once floated at €20 billion, has already narrowed to €12‑15 billion, mirroring a broader sell‑off that has also hit ammunition maker CSG, whose shares fell 60 % since its €30 billion listing.

Berlin redirected the frigate order to TKMS for eight Meko A‑200 vessels valued at roughly €11.6 billion, shifting focus to land‑system demand. Investors, still using Rheinmetall as a pricing reference, now confront a muted backdrop for the KNDS float. Nonetheless, the company’s robust order book should anchor its valuation despite lingering sector volatility.

The episode underscores how government procurement swings can reshape European defence equities, forcing investors to reassess exposure beyond traditional naval contracts in the coming months.
