Renk’s New Gearbox Unveils a Growth Chapter, but the Market Remains Unimpressed

Renk unveils ESM 280 transmission for wheeled vehicles, enters naval autonomous systems, and reports record €6.9B backlog, yet shares fall 45% from highs amid Israel export pause.

The Augsburg-based drive specialist Renk Group is pushing into new territory with the launch of the ESM 280, a high-performance transmission designed for armoured wheeled vehicles. The move marks a strategic departure from the company’s traditional focus on tracked platforms, opening up a fresh addressable market. The ESM 280, engineered for power outputs of up to 620 kilowatts and built to a 40-year service life, will be showcased at the Eurosatory 2026 defence exhibition in Paris from 15 to 19 June. Renk plans to present the system alongside a heavy unmanned ground vehicle developed with partner Patria.

The push into autonomous systems is gathering pace on multiple fronts. Renk has secured a contract to supply electric motors, clutches and transmissions for an unmanned surface vessel operated by a NATO member state, marking its entry into the naval domain. The company is now positioning itself as a driveline supplier for both land and sea-based autonomous platforms, diversifying its revenue base beyond traditional armoured vehicles.

Yet for all the operational momentum, the share price tells a different story. Renk’s stock closed on Friday at €49.00, shedding nearly five percent in a single session. That leaves the equity trading roughly 45 percent below its 52-week high of €88.73 and just a whisker above its 52-week low of €46.64. On a year-to-date basis, the shares have lost around 17 percent.

The disconnect between operational strength and market sentiment is stark. Renk’s order backlog hit a record €6.9 billion, with more than 90 percent of the planned full-year revenue already secured. Management has guided for annual sales above €1.5 billion and adjusted operating profit in the range of €255 million to €285 million. For the 2025 financial year, group revenue rose nearly 20 percent to €1.37 billion, while adjusted EBIT grew at a faster clip to €230 million, translating into a margin of 16.9 percent. The defence segment, which now accounts for roughly three-quarters of total sales, expanded by 24 percent.

One specific headwind weighed on first-quarter deliveries: exports to Israel were suspended under a German government embargo. That ban has since been lifted, and Renk expects revenues from that market to resume from the second quarter, with a meaningful contribution pencilled in for the full year.

The annual general meeting on 10 June will be a key event for shareholders. The board has proposed a dividend of €0.58 per share for 2025, a 38 percent increase on the prior year. The payment is scheduled for 15 June, with the ex-dividend date set for 11 June. The meeting will be held virtually, with no physical attendance permitted. The online shareholder portal opens by 19 May.

Alongside the dividend vote, the AGM will see a change at the top of the supervisory board. Dr. Klaus Richter, former CEO of the Diehl Group and a veteran of more than three decades in defence, aerospace and automotive, is set to be elected to the board and then take over as chairman. He succeeds Claus von Hermann, who is stepping down voluntarily. Von Hermann had overseen the company since its rebranding in 2023 and through its initial public offering in 2024.

Another item on the agenda goes beyond routine business. Shareholders will vote on a domination and profit transfer agreement between RENK Group AG and RENK GmbH. The German Association for the Protection of Securities Holdings has recommended approval.

Whether the AGM can shift the mood around the stock remains an open question. The combination of a record order book, a new product line, a rising dividend and a leadership refresh has so far failed to arrest the slide. The market appears to be waiting for tangible delivery — in the literal sense — before reassessing the equity’s valuation.
