A Correction That Surprises by Its Scale

Rheinmetall cut its annual operating margin forecast to 18.5%, down from 19% previously. The gap is half a point, but the stock fell between 15% and 16% at the open. The market punishment far exceeds the accounting adjustment. Investors are pricing in the prospect of military contracts that are slow to materialize.

South Korea, Laboratory of the Lag

The four leading South Korean defense groups (Hanwha Aerospace, LIG D&A, Hyundai Rotem and Korea Aerospace) were worth about 62,000 billion won at the end of October ($46.18 billion). Their 52-week peak reached 170,000 billion won, a loss of about 63%.

The mechanism shows up in their accounts. Hanwha Aerospace saw third-quarter operating profit fall more than 46% year on year, due to delivery schedule adjustments and one-off costs. Its stock is down more than 28% since January. Hyundai Rotem reports operating profit down more than 11% and a share price down about 60%. An analyst at KB Securities notes that governments have converted their spending commitments into approved budgets and then into orders more slowly than expected.

When Deliveries Are Locked In, the Stock Holds

Korea Aerospace Industries illustrates the counterexample: quarterly sales rose about 52% and operating profit 32%. Its stock is down only a little more than 8%. The punishment therefore hits first the groups whose revenue depends on delayed orders.

Order Books That Are Nonetheless Well Filled

In Europe, demand is not weakening. Leonardo reports an order book of €60.4 billion at the end of September, up 28% year on year. Hensoldt posts adjusted Ebitda up 33% over nine months and raises the lower end of its annual range. On the export side, Hanwha Aerospace this year won orders worth about €546 million for K9 howitzers in Spain and $922 million for rocket launchers in Norway.

What the Data Does Not Say

These figures call for nuance. Rheinmetall's margin cut remains limited. Leonardo's order book growth includes the scope effect linked to IDV. Korean stocks are also hit by a stronger won, capital flows toward semiconductors and already elevated valuations. Analysts also point to a shift in purchasing priorities toward drones and counter-drone defense. Finally, no trade data here confirms a slowdown in orders.

A Question of Timing Above All

The available facts describe a sector out of step between public promises and execution, not one losing demand. What happens next will play out over the coming quarters: the conversion of orders into deliveries, then into margins, will determine whether this correction was a simple valuation adjustment or a change of cycle.
