Renk's Record Backlog and Gearbox Milestone Can't Shake Off Short Sellers or Export Worries

Renk celebrates production of its 4,000th HSWL 354 gearbox, but shares slump amid rising short interest and a German export ban on Israeli defense deals threatening €100M in sales.

Renk Group is celebrating a manufacturing landmark — the start of production on its 4,000th HSWL 354 transmission for the Leopard 2 tank, a drivetrain that has been the backbone of Western armoured vehicles for more than four decades. But the Augsburg ceremony comes at a moment when the stock is under formidable pressure from two sides: a rising short interest and a government-imposed brake on defence exports to Israel that threatens up to €100 million in sales this year.

The company’s shares slipped another 1.25% on the day of the gearbox announcement, trading at €50.55 — below both the 50-day moving average of €51.45 and the 200-day level of €58.77. That leaves the equity 43% below its 52-week high of €88.73, a gap that has widened steadily since the start of the year. Year-to-date, Renk stock has shed more than 8%.

Hedge Funds Bet Against a Full Order Book

Short sellers have taken notice of the disconnect between operational strength and political headwinds. Citadel Advisors and PDT Partners have both boosted their short positions, pushing the total short ratio to 4.32% — nearly double the historical average. The export freeze imposed by Berlin is the chief source of their scepticism. Renk supplies gearbox systems for Israeli tanks, and the suspension of export licences directly hits a lucrative revenue stream.

Management is already responding. The company is relocating the affected production line to a new facility in Michigan, with $150 million earmarked for the site by 2030. Once operational, future orders linked to the Israeli programme will flow through US procurement channels, sidestepping German export controls entirely.

Yet the market wants proof, not promises. Renk’s first-quarter figures showed revenue of around €284 million and a record order intake of €582 million. The order backlog swelled to €6.9 billion, with more than 90% of the €1.5 billion revenue target for fiscal 2026 already under contract. The vehicle-mobility solutions segment was particularly strong: order intake there jumped 20.5% to €478.4 million, while segment revenue rose 11.2% to €191.5 million. The operating margin improved to 15%. Even so, investors appear fixated on the timing of cash conversion rather than the sheer volume of future work.

Large Shareholders Trade Places

The shareholder register has seen notable upheaval. KNDS, Renk's largest investor, sold a block of shares for €262 million, reducing its stake to roughly 10% and boosting the free float. On the other side, BlackRock lifted its holding to 4.44% in recent weeks, signalling that at least one major asset manager sees value at current levels.

The tug-of-war between sellers and buyers has left the stock stuck in a narrow band around €50, well below the levels where it started the year.

AGM to Vote on Dividend Hike and New Chairman

On 10 June, Renk will hold its annual general meeting — this year entirely virtual, starting at 10:00 CET. Shareholders are scheduled to approve a dividend of €0.58 per share, a significant increase from the prior year’s payout, with disbursement set for 15 June if the vote passes. The meeting will also install Dr. Klaus Richter as chairman of the supervisory board, a planned succession that brings a veteran industry insider to the role.

Beyond the formal agenda, the AGM offers management a platform to address the divergence between record operational metrics and a slumping stock price. The company is already developing the next generation of the HSWL 354, aimed at more powerful Leopard 2 powerpacks. But as long as export uncertainty and short-selling pressure linger, Renk’s equity looks likely to remain caught between defence-sector enthusiasm and political reality.
