Heidelberg Druck’s Radical Pivot: From Printing to Drones — But Investors Are Still Waiting for Proof
27.06.2026 - 14:16:44 | boerse-global.de
For a company that has spent 175 years mastering mechanical engineering, the jump into autonomous weapon systems is a wrenching departure. Heidelberger Druckmaschinen is now pouring resources into defence technology, but the stock’s performance tells a blunt story: down nearly 30% since January, it ended last week at €1.42, a level that leaves no doubt about the market’s scepticism.
The vehicle for this transformation is ONBERG, a joint venture with Ondas Autonomous Systems in which Heidelberg holds 49%. Production of drone-defence systems has already started in Brandenburg an der Havel, and at the ILA air show the venture signed a letter of intent with Ukrainian manufacturer Skyeton to mass-produce NATO-compliant reconnaissance drones. Management targets roughly €300 million in revenue from this business within a few years, yet defence currently contributes less than 2% of total turnover. The gap between ambition and delivery is vast.
Meanwhile, the core printing operation is contracting. Revenue has declined by about €140 million since 2023 to €2.29 billion, and the adjusted EBITDA margin of 6.6% fell well short of the stated goal. The restructuring is brutal: more than 550 severance agreements have been signed, production of the flagship Speedmaster CX 104 is moving entirely to China, and a new plant is being built in North Macedonia. Up to 200 staff from the traditional business are being shifted into the defence unit, a sign that the company is betting its future on a new identity.
That bet comes at a high cost. For the current financial year, the board forecasts a net loss in the low double-digit millions, with revenue staying flat but earnings quality deteriorating under heavy structural expenses. The dividend has been axed entirely, with analysts expecting no payouts until at least 2029. A credit facility has been expanded to €436 million, but financial headroom remains painfully thin. The group is effectively financing its own reinvention out of a shrinking base.
Should investors sell immediately? Or is it worth buying Heidelberger Druckmaschinen?
The chart reflects the tension. Heidelberg shares trade more than 17% below their 200-day moving average, a clear sign of a persistent downtrend. The 50-day average sits at €1.46, while the 52-week low of €1.29 is just 10% away. The relative strength index, at 45.7, indicates neither oversold conditions nor an imminent rebound. With annualised volatility above 47%, the stock is prone to sharp swings in either direction.
Bullish investors argue that if the new ventures start delivering real profits, the re-rating could be dramatic. The distance from the current price to the 52-week high of €2.54 — more than 40% — shows how much room for upside exists once credibility is restored. HD Advanced Technologies GmbH, the holding company for defence, energy, and charging infrastructure, is the vehicle to watch.
The bear case is equally clear. The ILA letter of intent is not a firm order; series production and binding revenue remain elusive. The transformation requires heavy upfront investment without an immediate payoff in margins. If the stock slips below €1.29, the next stop could be a test of the psychological €1 mark. The market is demanding proof, not promises.
The core test is whether an increasingly efficient print business can generate enough cash to bankroll the pivot. So far the numbers have not backed the narrative. The company needs to show that cost cuts are translating into better margins, not just minimising losses.
The next big milestone comes on 23 July 2026, when shareholders gather in Mannheim for the annual general meeting. The formal confirmation of the dividend suspension will be on the agenda, but the real issue is whether the board can demonstrate that the transformation is on track. If cost levers fail to produce a visible improvement in earnings, the risk of a prohibitively expensive restructuring will dominate the conversation.
Heidelberg Druck is no longer a printing-machine company. It is a high-stakes bet on a metamorphosis from industrial workhorse to defence-technology player. At €1.42, the stock captures both the opportunity and the deep uncertainty. Until the financials catch up with the strategy, the sceptics will keep the upper hand.
