Heidelberger Druckmaschinen's High-Wire Act: Core Business Strain Meets Drone Defense Ambition

Heidelberger Druck navigates partner insolvency in core printing while investing in a new drone defense subsidiary, testing investor patience as shares fall over 31%.

Heidelberger Druckmaschinen AG is attempting a precarious balancing act. As its traditional printing machinery business contends with a key partner's insolvency, the company is simultaneously building a new defense subsidiary focused on drone technology. This dual-track strategy is testing investor confidence, reflected in a share price that has plummeted over 31% since the start of the year to trade at just €1.40.

The strain is evident in the core industrial printing segment. Hardware supplier Manroland Sheetfed entered a protective shield procedure in early March, forcing Heidelberg to take over sales and digital integration for their jointly developed Cartonmaster CX 145 machine solo. The first demonstration unit of this machine recently commenced operations at the Wiesloch-Walldorf headquarters. Looking to capitalize on rising demand for paper packaging, the group also plans a world premiere in flexo printing at the interpack trade show in May, targeting significantly higher production speeds.

Financially, the picture is mixed. Group revenue for the first nine months climbed six percent to €1.6 billion. However, the adjusted EBITDA margin is now expected to hit only the lower end of the targeted range of up to eight percent for the full year. In the third quarter alone, adjusted EBITDA fell from €55 million to €50 million. Analysts attribute the pressure to costly transformation efforts and weaker order intake in the classic business.

A significant bright spot emerged from overseas. At a recent trade fair in São Paulo, Brazil, the company secured orders worth over €30 million, underscoring Latin America's growing importance as a key growth region.

Parallel to these core challenges, Heidelberg's strategic bet rests on the joint venture ONBERG Autonomous Systems. Developed with Ondas Autonomous Systems, the venture aims to create scalable drone defense systems at a site in Brandenburg an der Havel. The technology is intended for protecting critical infrastructure in Germany and providing direct defense support in Ukraine. Management will present the technical roadmap for ONBERG in mid-April.

This ambitious pivot, however, requires considerable patience. The leadership team does not anticipate meaningful revenue contributions from the new defense segment before the second half of 2026, with operational break-even projected a year later. The company also remains initially dependent on suppliers from the USA and Israel for key components.

The financing for this expansive transformation is secured for now by a credit line extended until 2030. Investors will get a crucial look at the operational stability of this two-pronged approach on June 10, 2026, when the full annual report for 2025/26 is published. This document must demonstrate whether profits from the core business can sufficiently offset the high start-up costs of the new ventures and the burdens of its partner's insolvency. The ordinary annual general meeting is scheduled to follow on July 23, 2026.
