Renk Wins Saab Work and Seals UK Submarine Deal, but DZ Bank Trims Its Fair Value to €56

Renk's latest run of announcements splits cleanly into two piles: contracts that are signed, and programmes that are merely being pitched. The distinction matters more than ever after DZ Bank lowered its fair value on the stock from €64 to €56 on 23 October, according to media reports, while leaving its "Buy" rating in place.

That combination — a positive investment call paired with a reduced valuation yardstick — is easily misread. The cut is not a sell signal, nor is it an unqualified endorsement of the previous view. It simply pulls back the price the bank is willing to put on the business even as it stays constructive on the equity.

What Is Actually Booked

On the firm side of the ledger sits the completed acquisition of David Brown Defence from Stellex Capital Management. All required regulatory approvals are in hand, and the business now trades as RENK UK Huddersfield. The site is earmarked as a competence centre for submarine propulsion systems. Renk puts order backlog and pipeline together at more than £700 million for the 2026 to 2030 period — a figure that explicitly includes the pipeline and therefore should not be read as firmly booked business. Neither the purchase price nor the contract terms were disclosed.

Naval work also brought a confirmed order: Saab has tasked RENK Magnet-Motor with three Stirling power generation systems for a submarine programme run by a NATO member state. Renk describes it as the third major order within the existing collaboration, evidence of repeat business rather than a benchmark for the group as a whole.

Land systems contributed a firmer number still. The order expansion agreed with KNDS Deutschland on 14 October covers gearboxes, transmission control units and gear selector switches, with Renk putting the volume at around €130 million. Deliveries are due to begin in 2029 and run through 2032.

A Gearbox Pitch, Not a Purchase Order

Separately, Renk on Friday flagged further development of its HSWL 406 gearbox for future heavy tracked vehicles. No order accompanied the announcement. The unit is rated for outputs of up to 1,400 kW and is aimed at international procurement programmes, among them Italy's NMBT effort led by the Leonardo Rheinmetall Military Vehicles joint venture.

That is a technical positioning play for vehicle programmes that may or may not materialise. It does not constitute additional order intake from Italy, and any eventual involvement cannot yet be equated with a contracted delivery scope. The contrast with the KNDS deal is stark: there, volume and delivery window are already fixed.

A Divestment That Reshapes the Base

Complicating the earnings picture is the agreed sale of the plain bearings business to Miba. Renk has signed a binding contract, though the purchase price was not disclosed and completion remains subject to regulatory clearance — so unlike the British acquisition, this transaction is not yet closed.

Around two weeks ago, Renk adjusted its annual guidance in the wake of that agreement. It now points to revenue of roughly €1.4 billion and adjusted EBIT of €240 million to €255 million. The plain bearings unit is to be reported as discontinued operations from the fourth quarter, which is why the guidance reset is tied to the changed scope of the business rather than to any deterioration in the retained operations.

The next fixed point for investors is Thursday, when Renk publishes its nine-month statement alongside a conference call. Until then, the documented picture is one of completed and contracted progress on the operating side, set against a lower valuation benchmark from DZ Bank and a forecast base redrawn by the planned disposal.
