Heidelberger Druckmaschinen's Defense Foray Triggers a Profit Warning

Heidelberger Druckmaschinen cuts its 2025/26 EBITDA margin forecast due to upfront costs for its new counter-drone systems joint venture, ONBERG, targeting Germany's critical infrastructure market.

A strategic pivot into drone defense systems has come at a steep initial cost for Heidelberger Druckmaschinen. The German printing press specialist has been forced to revise its earnings forecast for the 2025/26 financial year, citing weaker product mix and, more significantly, upfront investments in its new armaments venture. The company now anticipates an adjusted EBITDA margin of approximately 6.6%, down from the previous year's 7.1%.

The operational catalyst for this financial pressure is the launch of ONBERG Autonomous Systems, a joint venture with US-Israeli partner Ondas Autonomous Systems. Production officially commenced on April 14 at a 30,000-square-meter facility in Brandenburg an der Havel. The site, previously used for precision printing components, will now manufacture integrated counter-drone systems. Approximately 380 employees are involved in the operation.

This move is a direct response to regulatory demands. Germany's KRITIS umbrella law mandates around 2,000 critical infrastructure operators—including airports, energy suppliers, and military sites—to enhance their protective measures. The need has intensified following a rise in drone sightings since Russia's invasion of Ukraine. ONBERG is positioning itself as a full-spectrum provider, offering detection, evaluation, and neutralization, primarily through its "Iron Drone Raider" system which uses autonomous drones to intercept threats.

The venture is pursuing a dual-use strategy for civilian and military applications, with parallel market entry in Germany and Ukraine. The conflict zone provides a real-world testing ground for system development. However, scaling serial production presents a major hurdle, with strict certifications, export controls, and fragile electronics supply chains posing tangible delay risks.

Financially, the company does not expect material revenue from drone defense until the second half of 2026. The operational break-even point is projected roughly twelve months after full production ramp-up. The full impact of these upfront costs on the current year's results will be detailed when Heidelberger Druckmaschinen publishes its audited annual report on June 10. Preliminary figures indicate the group met its currency-adjusted sales target and maintained stable order intake.

Analyst sentiment on the stock remains cautiously optimistic about the long-term diversification play. Three analysts recommend buying the shares, with an average price target of €2.25, ranging from €1.70 to €2.75. This suggests significant potential upside from current levels, reflecting a belief that the promising defense shift could eventually strengthen profitability, despite the near-term margin pain.
