Rheinmetall’s stock has shed nearly a quarter of its value since the start of 2026, yet the Düsseldorf defence contractor is sitting on a record €73 billion order book and a pipeline of contracts that could reshape European security. That disconnect between operational strength and market sentiment is sharpening as three distinct headwinds converge: a constitutional challenge to Germany’s military procurement law, the departure of a major US shareholder, and a frigate programme that keeps ballooning in both cost and delay.
The most far-reaching uncertainty stems from a Düsseldorf courtroom. On 22 May, the Higher Regional Court (OLG) suspended a procurement review and referred a core clause of the Bundeswehr procurement acceleration law to the Federal Constitutional Court. The judges argue that §16(1) of the law—which denies losing bidders the automatic suspensive effect of an immediate appeal—infringes the constitutional right to effective legal protection guaranteed by Article 19(4) of the Basic Law. The immediate case concerns package stations for military clothing and does not involve Rheinmetall directly. But any ruling from Karlsruhe could redefine the legal framework for all future Bundeswehr tenders, injecting fresh uncertainty into the very process the law was designed to speed up.
That matters deeply for the Arminius programme, the single biggest prize on Rheinmetall’s horizon. The plan to supply up to 3,000 Boxer armoured vehicles carries a potential total volume of around €40 billion, with an initial firm order worth €12.5 billion. CEO Armin Papperger recently pushed the expected signature from the first half of 2026 into the second half, and the legal cloud over procurement timelines may give both Berlin and the company further reason to pause.
Investor confidence is also fraying. US asset manager FMR LLC reduced its stake to below the 3% disclosure threshold, with the holding falling from 3.09% to under 3% on 18 May; the notification arrived three days later. The retreat comes alongside a marked reassessment by sell-side analysts. UBS cut its price target from €2,200 to €1,600 while keeping a Buy rating, and Jefferies lowered its target from €2,220 to €1,890, citing higher implementation risks. Barclays stands out by reaffirming an Overweight rating and a €2,035 target, which implies more than 60% upside from the current share price of €1,221.40.
Should investors sell immediately? Or is it worth buying Rheinmetall?
That price, however, remains deep in the red. On Monday the stock traded at €1,233.20, up 0.97% on the day and 4.72% over the past week. Yet year-to-date the decline stands at 23%, and the shares are trading 24.9% below their 200-day moving average. The 52-week low of €1,118, set on 13 May, is still only about 9% below the current level.
Adding another layer of strain is the F126 frigate programme. Rheinmetall is demanding roughly €12 billion from the federal government to take over the project from the Dutch DAMEN shipyard, pushing the total estimated cost for six warships to around €14 billion. Berlin has already allocated €2 billion for the initial phase. The first frigate is now scheduled for delivery in 2032—four years later than originally planned—after software issues delayed the transfer of design plans from the Netherlands to German shipyards.
None of this invalidates the operational story. The order backlog, including framework contracts, reached €73 billion as of 31 March, up from €56 billion a year earlier. Management has already secured contracts covering roughly 97% of the planned 2026 revenue and is guiding for sales between €14 billion and €14.5 billion with an operating margin of 19%. The next quarterly results are due on 6 August 2026. Until then, contract announcements, the outcome of the F126 negotiations, and—perhaps most critically—the signal from Karlsruhe will determine whether Rheinmetall can translate its record backlog into a share price recovery.
