Rheinmetall’s Debt Draws a Crowd Even as Its Shares Can’t Catch a Break

Investors embrace Rheinmetall's €500M bond with 3.375% coupon, but shares slump 39% from highs amid revenue miss, negative free cash flow, and capacity bottlenecks.

When Rheinmetall came to market with a €500 million corporate bond in late May, it was a test of investor appetite for a defence giant whose stock has been in retreat. The answer came loud and clear: the order book was 7.8 times oversubscribed. With a coupon of 3.375% and a maturity stretching to May 2031, the issue marked the company’s first conventional corporate bond since 2010. Creditors, it seems, are willing to bet Rheinmetall can manage its debt over the next five years. The same cannot be said for equity holders.

The shares closed at €1,208.60 — a 39.4% plunge from the 52-week high of €1,995 and 25.9% below the 200-day moving average. Since the start of the year, the stock has shed 24.5% of its value. An attempted recovery from the mid-May trough of €1,118 has lifted the price by just 8.1%, leaving the relative strength index at a middling 58.1. Annualised 30-day volatility of 53.8% hints at a market that flinches at every headline.

The dissonance between the bond’s reception and the share price performance is rooted in a single problem: execution. Rheinmetall’s order backlog hit €73 billion as of 31 March, up from €56 billion a year earlier and representing more than seven times 2025 revenue. The book-to-bill ratio sits well above 2, meaning the group is winning new contracts at twice the pace it can convert them into sales. Yet the first-quarter results published in May laid bare the bottleneck. Revenue came in at €1.94 billion, roughly €300 million short of analyst expectations. Operating profit also missed forecasts, and free cash flow turned negative as the company pours money into expanding production capacity, building inventories and securing pre-production components.

The problem is not demand — global military spending hit a record $2.89 trillion in 2025, the eleventh consecutive annual increase, according to the Stockholm International Peace Research Institute. European outlays rose 14% to $864 billion, with Germany the largest spender on the continent outside Russia. But the composition of that demand is shifting. Budgets are flowing disproportionately towards cruise missiles, air defence and autonomous systems, while classic land-based platforms such as 155mm artillery and main battle tanks face increasing competition for funding. Rheinmetall remains heavily weighted towards the latter, even as its weapons and munitions segment targets growth to €14–16 billion by 2030. The problem: industry-wide capacity expansion in 155mm artillery is expected to drive price pressure over the medium term.

Management is aware of the challenge. At the annual general meeting in May, CEO Armin Papperger confirmed the company has entered production of kamikaze drones. More promising in analysts’ eyes is the air-defence business, which is forecast to grow from a small base to between €3 billion and €4 billion. The joint venture for cruise missiles established in April is seen as a step in the right direction, though still in its early stages. Meanwhile the much-anticipated “Arminius” order for Boxer armoured vehicles from the German military has slipped; Papperger does not expect a contract before the second half of the year.

“Investors are becoming very picky and very selective,” said Loredana Muharremi, equity analyst at Morningstar. The days when a tailwind from political rhetoric was enough to lift the share price have ended. For 2026, many analysts see a phase of consolidation, in which the initial euphoria over Europe’s military spending increases gives way to a hard-nosed assessment of each company’s ability to deliver.

The bond’s heavy oversubscription tells a different story. The euro-denominated issue was snapped up by institutional buyers who appear to be taking the long view — they are underwriting the thesis that European rearmament will span years, not quarters. The capital markets are being tapped to fund the expansion of capacity, supply chains and personnel long before that investment translates into revenue. That is a message suited to creditors, not to equity investors who have already punished the stock for a lowered 2025 profit guidance, weak first-quarter numbers, delivery delays on tanks and quality issues at a munitions factory in Murcia.

Rheinmetall’s acquisition of NVL in the first quarter turned the group into a full-service provider across all military branches — from unmanned naval craft to frigates — but the breadth of the offering does little to address near-term production constraints. The company expects to produce only about ten new air-defence systems in 2026, with a meaningful ramp-up not coming until 2027. That gap between ordering and invoicing is what leaves the equity market cold.

Forward earnings multiples have compressed sharply from peaks above 100 to around 33, though that still leaves a hefty premium over Lockheed Martin’s 18. To justify it, Rheinmetall must deliver structurally higher growth. The second quarter of 2026 is the next proving ground: management has flagged stronger revenue and order intake, with large contracts expected in the naval and vehicle divisions. The prior quarter’s shortfall was attributed to delivery timing, not a change in annual demand, and the company insists its pipeline is intact.

That may be enough for bondholders, who have already shown their hand. Equity holders demand more than a pipeline — they want proof that the production machine can keep pace with the backlog. For now, Rheinmetall remains a story of two markets: one that trusts the trajectory and another that is waiting to see the wheels move.
