Heidelberg Navigates Partner Fallout and Defense Spending as Margin Targets Slip

Heidelberger Druckmaschinen is facing an unusually tangled set of challenges. The printing equipment maker must plug a gap left by a struggling hardware supplier, fund the ramp-up of a drone-defense venture, and explain why earnings will fall short of expectations — all while its stock has halved since the July 2025 peak. Shares now trade around €1.37 to €1.39, well below their 50-day moving average.

The immediate headache stems from Manroland Sheetfed, the partner behind the Cartonmaster CX 145, Heidelberg’s flagship product for folding-carton and packaging printing. With Manroland in difficulties, Heidelberg has taken over distribution as a system integrator without a fixed hardware partner. That keeps customer relationships intact for now but leaves the structural dependency unresolved. To bolster its packaging credentials, Heidelberg unveiled a new flexo printing system at the interpack 2026 trade fair in Düsseldorf, targeting up to 90% machine availability and a speed of 600 metres per minute. The system’s Intellimatch scanner automatically sets up the printing units, while a modular design allows future reconfiguration. Packaging and label printing remain the strategic core for Heidelberg, underpinned by the global trend toward rising demand for packaged goods.

The margin picture has darkened nonetheless. In April, management released preliminary figures for the current fiscal year 2025/26, flagging an adjusted EBITDA margin of around 6.6% — down from 7.1% in the prior period and a retreat from the original goal of improving on that level. Three factors are blamed: the outbreak of the Iran conflict in late February, which abruptly chilled customer investment decisions; an unfavourable product mix in the final quarter; and negative currency effects. Currency-adjusted revenue remains on target, however, and order intake has tracked the pattern of prior years.

Should investors sell immediately? Or is it worth buying Heidelberger Druckmaschinen?

The margin shortfall is compounded by start-up costs for HD Advanced Technologies, a division focused on defence applications. In April, the group’s joint venture ONBERG Autonomous Systems became operational, with HD Advanced Technologies holding a 49% stake. The partner is US-Israeli specialist Ondas Autonomous Systems. The venture aims to produce autonomous drone-defence systems for critical infrastructure in Europe, combining detection, command and countermeasures in a single architecture. Heidelberg will manufacture the systems at its site in Brandenburg an der Havel, where around 380 employees currently work. The German KRITIS infrastructure protection law provides a tailwind, requiring thousands of facilities to legally upgrade their security measures. The total addressable market is estimated at nearly $10 billion over the next five years.

Meaningful revenue from the drone business is not expected until the second half of calendar 2026, and some internal guidance points to the latter part of fiscal 2026/27. Management targets operational break-even once production has run at full capacity for a full year. Until then, the core printing machinery business must bear all development costs.

The supervisory board is backing the strategic shift. It has extended the contracts of CEO Jürgen Otto and sales director Dr. David Schmedding — Otto through to July 2029, Schmedding to June 2031. The transformation from a pure press manufacturer to a wider technology group thus continues unabated, though near-term headwinds are proving severe.

The next major catalyst comes on June 10, when Heidelberg publishes its audited annual results. Alongside final fiscal-year numbers, the market expects concrete revenue forecasts for the new drone segment and, more critically, a clearer view of how much the transformation will ultimately cost — and whether the packaging strategy can hold up without a stable hardware partner.
