Rheinmetall’s Record Backlog Fails to Shield the Stock From Margin Squeeze and Shifting NATO Doctrine

Despite €73B backlog, Rheinmetall shares hover near 52-week low amid margin cuts, NATO pivot from tanks, and negative free cash flow. Next earnings report is critical.

Rheinmetall closed Tuesday at €977.00, bringing its decline from the September 2025 record high of €1,995.00 to 51%. The irony is hard to miss: the defence group’s order backlog stood at €63.8 billion at year-end 2025 and some reports now peg it as high as €73 billion, yet the stock sits just 8% above its 52-week low of €902.50. The market is no longer buying a pure growth story; it wants proof of profitability and cash conversion.

That proof has been slow to materialise. In March 2026, Rheinmetall trimmed its operating margin guidance to around 19%, and first-quarter revenue of €1.94 billion missed consensus. Free cash flow turned negative, weighed down by heavy investment and rising working capital. The result was a sharp sell-off in May. Investors who once cheered bulging order books are now scrutinising the gap between top-line promise and bottom-line delivery.

Compounding the operational pressure is a strategic pivot from NATO. The alliance’s Ankara summit in early July 2026 marked a clear shift in priorities: away from heavy armoured vehicles toward air defence, drone technology and autonomous warfare. For a company long synonymous with tank production, this is an existential threat to its equity narrative. Analysts estimate that the share of operating profit from armoured vehicles could shrink from roughly 45% in 2023 to about 20% by 2030. The stock’s 35.3% discount to its 200-day moving average of €1,510.16 reflects the depth of market scepticism.

Additional headwinds include uncertainty around the F126 frigate programme and Rheinmetall’s failure to hit its ambitious “Nomination” target of €20 billion. Technically, the shares look washed out: the RSI hovers near 36, and 30-day annualised volatility of 68.94% is more typical of a speculative small-cap than a €46.23 billion DAX heavyweight. The 50-day and 100-day moving averages at €1,152.15 and €1,338.03 respectively confirm a well-established downtrend.

Rheinmetall is not standing still. On July 13, it took full control of the “InterRoC VII” research project for highly automated military convoys on behalf of the German procurement office. A collaboration with Lockheed Martin to produce ATACMS precision weapons in Unterlüß underscores the push into high-tech munitions. The company is trying to shed its image as a heavy machinery builder and recast itself as a systems house for advanced defence electronics. But while these segments are growing rapidly, their absolute size remains too small to offset the shrinking armour business.

Many analysts maintain a positive long-term view, arguing that Europe’s rearmament cycle is structural and intact. The message is that the sector’s tailwinds are real, but the valuations of previous years had overshot the operating reality. The next earnings release on August 6 will be a watershed: it must show whether the weak first quarter was an aberration or a symptom of deeper issues.

For now, the stock is pricing in a painful transition from the old world of heavy armour to the new world of autonomy and air defence. Rheinmetall has the orders — the question is whether it can turn them into cash, margins and a credible case for being re-rated as a technology company rather than a tank builder.
