Renk Links Arms with Patria for Autonomous Tank as €6.9bn Backlog Fails to Impress Markets

Renk's share price drops 17% YTD amid sector rotation and index removal, even as record €6.9B backlog and autonomous vehicle partnership signal strong growth.

Renk is seeking a technological edge to break free from a stubborn stock slide. At the Eurosatory defence exhibition in Paris, the Augsburg-based drivetrain specialist joined forces with Finnish partner Patria to showcase a heavy unmanned ground vehicle. Renk supplies the gearbox and a fully digital drive-by-wire architecture — a cable-free steering system that forms the backbone for future autonomous land platforms. Series production is slated to begin in 2027, giving investors a tangible milestone beyond the current order frenzy.

That operational momentum is already formidable. Renk booked a record €582 million in new orders during the first quarter, pushing the aggregate backlog to €6.9 billion — meaning nearly all of the company’s 2026 revenue targets are locked in. Adjusted operating profit rose by just over 10% to €42.4 million, and management is sticking to its full-year guidance of more than €1.5 billion in sales.

Yet the share price tells a very different story. After sliding roughly 17% since the start of the year, the stock changed hands at €45.24 on Monday, nearly 6% lower in a single session. The trigger was not a missed delivery but a broad sector rotation: investors dumped European defence names as hopes of a ceasefire in the Middle East gathered steam. Rheinmetall and Hensoldt also fell, but Renk was hit hardest, leaving the company with a market capitalisation of around €5 billion.

Technical headwinds compounded the geopolitical jitters. Renk was dropped from the iSTOXX Europe Centenary Select 30 Index on 22 June, forcing index-tracking funds to offload their positions. That automated selling weighed on the stock even as the company’s underlying performance strengthened.

Management now faces a critical test. Over the coming days, executives are scheduled to present at investor conferences in London and Baden-Baden, where they must convince the market that the order backlog is not a mirage and that margins are sustainable. Official half-year results are due on 6 August, and the Berenberg analysts, who maintain a buy rating with a €72 price target, argue that the current valuation fails to reflect Renk’s escalating exposure to European defence spending. The company plans to push the defence share of revenue to 90% by 2030.

For now, the gap between a record backlog and a depressed share price remains wide. If the second-quarter numbers confirm margin momentum, the recent geopolitical discount may prove short-lived — and the autonomous tank programme gives Renk a narrative that reaches well beyond the next earnings cycle.
