Rheinmetall’s Production Machine Is Roaring, but the Stock Market Is Plugging Its Ears

Rheinmetall's artillery shell capacity soars to 1.1M units, but a 14% share price drop and high P/E ratio of 36.6 signal market skepticism over margins and cash flow.

The numbers coming out of Rheinmetall’s factories are staggering. The German defence group has ramped up its annual capacity for artillery shells from 70,000 to 1.1 million units — a jump that now outstrips the entire production capacity of the United States in that segment. Output of medium-calibre ammunition has quintupled to four million units, while military truck production has surged from 600 to 4,500 vehicles per year. Roughly 65% of this output is destined for export, predominantly to NATO allies.

Yet for all that industrial muscle, the company’s share price has been heading in the opposite direction. Since the start of the year, the stock has shed nearly 14% of its value, and on 24 April it touched a 12-month low of €1,309.80. A modest bounce at the start of this week — the shares gained around 2% — offered a flicker of relief, but the broader trend remains unmistakably bearish.

A Valuation That Demands Perfection

The disconnect between operational performance and market sentiment is stark. Revenue for the 2025 financial year climbed 29% to just under €10 billion, and management is targeting a further 40% to 45% jump in 2026, which would lift sales to between €14.0 billion and €14.5 billion. The operating margin is expected to come in at roughly 19%.

But investors are balking at the price tag. The forward price-to-earnings ratio for 2026 stands at 36.6 — a hefty premium to US peers such as General Dynamics (19.2), Lockheed Martin (17.2) and RTX (25.4). For that kind of multiple, the market wants certainty that the massive capacity expansion will translate into sustainable profitability. So far, that assurance has been lacking.

The free cash flow picture adds to the uncertainty. Inflationary pressures on defence inputs have already forced the German military to halt some procurement projects — a warning sign for margin development that analysts are watching closely.

Technical Hurdles and a Key Date

From a chart perspective, this week’s recovery is little more than a hopeful candle. For a genuine trend reversal, the stock would need to reclaim and hold the €1,500 to €1,550 zone. The MACD is showing bullish divergence, which offers some encouragement, but concrete buy signals have yet to materialise. The distance to the 200-day moving line has stretched to nearly 20%, underscoring how far the shares have fallen from grace.

The next major test arrives on 7 May, when Rheinmetall reports first-quarter results. Those numbers will need to validate the lofty expectations baked into the valuation. The annual general meeting follows on 12 May, with the dividend due to be paid within three trading days after that.

Management is also pressing ahead with a major hiring drive, targeting a workforce of 70,000 employees to support the growth trajectory. But until the market sees hard evidence that the capacity build-out is delivering on margins and cash flow, the shares may struggle to escape the gravitational pull of their 52-week low.
