Rheinmetall chief executive Armin Theodor Papperger has spent €702,780 of his own money buying shares in the German defence group, days after the company cut its guidance for 2026 for the second time in three months. According to mandatory disclosures, he bought shares worth €502,484.40 on Thursday and a further €200,295.60 on Friday.

The Thursday purchase covered 585 shares at an aggregate average price of €858.9477 on Xetra, the Frankfurt exchange, as set out in the company's regulatory filing. The Friday transaction covered 249 shares at €804.40 on Tradegate. The timing was pointed: the buying came a day after Rheinmetall trimmed its full-year outlook, and hours before at least one major brokerage walked back its bullish stance on the stock.

Rheinmetall disclosed the downgrade on Wednesday and set out the details on Thursday. Delays in the Boxer project known as Arminius, together with slower lot acceptances for artillery ammunition, pushed the company to cut its 2026 revenue forecast to roughly €13.2 billion, down from a previous range of €13.7 billion to €14.2 billion. Profitability expectations came down alongside the top line, with the operating margin now guided at around 18.5%, down from approximately 19%. Deposits and revenue tied to the affected programmes are shifting into 2027, management said.

The cut was the second in three months, and analysts quoted by dpa-AFX flagged it as the fifth revenue or profit warning in eleven months. Reuters reported on Thursday that the guidance cut also reflected lower-than-expected proceeds from newer activities, including the cooperation with Destinus.

Set against the trimmed outlook, the numbers already booked look robust. Revenue for the first nine months of 2026 reached €8.376 billion, up 38% year on year. Operating profit rose to €1,339 million, an increase of about 68%, and the operating margin for the period came in at 16.0%. There were fresh deliveries to point to as well: on 29 October Rheinmetall handed over the first series-production Caracal vehicles to the German and Dutch armed forces, with more than 1,500 units slated for delivery through 2030.

But the cash flow tells a harder story. The nine-month figures show an outflow of €1,698 million, set against an order backlog of €78.0 billion as of 30 September 2026. The combination of an enormous pipeline of future work and a substantial drain on liquidity is the dilemma facing investors: additional bookings only strengthen the outlook if Rheinmetall simultaneously makes headway in working them off.

The sell side is not waiting for that proof. Bernstein Research cut its price target to €1,000 from €1,200 on Friday and downgraded the stock to "Market-Perform" from "Outperform", according to media reports. Other research houses also dropped their recommendations or lowered targets, dpa-AFX reported. The stock closed Friday at €818.00, down 1.4% on the session, below the level at which Papperger had bought the previous day.

The next scheduled checkpoint is Rheinmetall's capital markets day in Hamburg, running from 25 to 27 November 2026. Investors will be listening for detail on how the delayed projects will be worked off, what the financial impact of growth will be, and how the company intends to turn its order backlog into more predictable revenue and better cash flow. Papperger has backed his view with €702,780. The market now wants the schedule to back it up.
