Renk’s NATO Drone Deal and Record Orders Mask a Cash Flow Headache

German defense firm Renk sees record orders and naval pivot but faces cash flow issues and an Israeli export ban, with shares up 18% but far from 2025 highs.

The German defence contractor Renk is navigating a paradox: its order book is bursting at the seams, yet a stubborn cash flow problem and a geopolitical export ban are testing investor patience. The company has secured a contract to supply drive components for a NATO member’s unmanned surface vessel, marking a strategic push into maritime and autonomous systems. Shares have responded positively, climbing roughly 18 percent over the past month to trade at €54.97, but the stock remains well below its 2025 peak of nearly €89.

A Pivot to the Seas

The new naval package includes electric motors, gearboxes, and couplings, with first deliveries scheduled for the third quarter of 2026. Renk will use modular marine gearboxes from its own production line. The contract value has not been disclosed, but the deal underscores a broader shift: NATO allies are pouring investment into unmanned maritime platforms, which offer lower costs and greater tactical flexibility than crewed vessels.

This move helps Renk reduce its reliance on traditional land-based defence equipment. The company’s core business has long been tied to tank transmissions, but the landscape is changing. In late April, another NATO state placed a €157 million order for tank gearboxes—widely believed to be for Poland’s expanding fleet of South Korean K2 main battle tanks. That business remains robust, but the future increasingly points to the water.

The Israeli Export Embargo

A political headache is forcing Renk to rethink its production footprint. The German government has suspended certain arms exports to Israel, directly affecting gearbox systems for Merkava and Namer armoured vehicles. Renk estimates the revenue hit for 2026 at between €80 million and €100 million.

The company’s response is structural rather than reactive. It plans to shift the affected production to its facility in Muskegon, Michigan, investing $150 million there by 2030. Future Israeli orders would then be routed through the US Foreign Military Sales programme, sidestepping German export controls entirely. Separately, Renk is building a service and production hub in Poland, with a total investment of €500 million over five years, to serve customers in Ukraine and the Baltic states.

Record Orders, but Cash Is King

Renk’s order intake for the first quarter of 2026 is expected to hit a record €585 million, according to mwb research, far above the previous quarterly range of €400 million to €500 million. The company itself described Q1 as a record quarter during a pre-close call on 22 April. The full-year target of €2 billion in new orders now looks easily achievable.

Yet the financials tell a more complicated story. Renk posted record revenue of €1.37 billion in 2025, and its order backlog swelled to €6.68 billion. But free cash flow disappointed badly: management had targeted a cash conversion rate above 80 percent, but achieved only 47 percent. For Q1 2026, analysts are watching whether roughly €200 million in delayed payments have finally been converted into cash.

The company is sticking to its full-year guidance of revenue above €1.5 billion and adjusted operating profit between €255 million and €285 million. But the cash flow gap remains the unresolved issue.

Analyst Divergence and the Dividend Question

Opinions on Renk’s stock are sharply divided. Jefferies has a price target of €78, while mwb research sees fair value at €53. Deutsche Bank analyst Christophe Menard recently raised his target to €73 with a “Buy” rating, citing the strong order momentum.

Shareholders have a dividend proposal to consider at the annual general meeting on 10 June: €0.58 per share, a 38 percent increase from the prior year. That payout will be put to a vote alongside the Q1 results due on 6 May, which will provide the first hard test of whether the record order book can finally translate into stronger cash generation.

Renk’s long-term ambition is clear. With a near-€6.7 billion order backlog and a strategy that blends traditional land defence with maritime drones and autonomous systems, the company is positioning for the next decade. But for now, the market is watching the numbers that matter most: cash in the door, not just orders on the books.
