Heidelberger Druck's New Flexo Lineup Confronts Softer Demand and Margin Pressure

Heidelberg's packaging push with Boardmaster and partnerships contrasts with falling stock, margin pressure from Iran conflict, and costly ONBERG defense venture.

The message from Heidelberger Druckmaschinen's latest trade-show presence was clear: the company is betting big on packaging. But the stock's slide below its 50-day moving average tells a more cautious tale. On 11 May, the shares touched €1.41, roughly half the 52-week peak of €2.81 reached in July 2025. A few days earlier, the Xetra closing price was even lower at €1.388, putting the twelve-month trough of €1.32 within striking distance.

The operational backdrop explains the dissonance. When Heidelberg released preliminary figures for fiscal 2025/26 in mid-April, it flagged that the adjusted EBITDA margin would come in at around 6.6% — well below the prior year's 7.1% and short of the improvement management had targeted. The company cited a sudden drop in customer investment appetite from late February, linked to the Iran conflict, along with an unfavourable product mix in the final quarter and persistent currency headwinds. Earnings per share, however, did show a gradual recovery: from minus €0.04 in the first quarter to €0.04 in the second and €0.06 in the third. On a currency-adjusted basis, revenues remain on track to hit the full-year target, and the order intake continued the trend of earlier quarters.

At the interpack trade fair in Düsseldorf (7–13 May), Heidelberg unveiled the Boardmaster, a flexo-roll printing system for sustainable cardboard packaging that runs at up to 600 metres per minute. The company claims this doubles productivity, aided by the new Intellimatch pre-press scanner that calibrates printing units fully automatically. A modular design lets customers reconfigure the system as market conditions shift. Simultaneously, Heidelberg announced three partnerships — with Pack-Smart, Inc., Metsä Board and the Pfenning-Gruppe — aimed at a seamless workflow from substrate selection to digital integration via its Prinect software, which now includes an AI assistant. Also on show was the Cartonmaster CX 145, which Heidelberg now sells and digitally integrates on its own, positioning itself as an end-to-end system integrator for packaging production.

Beyond the core packaging push, the company is making a costly bet on defence through the ONBERG joint venture with Ondas Autonomous Systems, which focuses on drone countermeasures. Start-up costs are weighing on current earnings, and management does not expect material revenues from this arm before the second half of the year. Market observers project that ONBERG could generate between €80 million and €150 million in 2027 and more than €200 million in 2028, but those figures remain speculative without concrete orders. These non-core investments, alongside accelerated spending in the defence unit HD Advanced Technologies, are squeezing margins further.

Regional performance offers a partial offset. Heidelberg secured around €30 million in orders at the Expoprint trade show in São Paulo in late March. In the Americas, order intake rose 17% in the third quarter. Over the first nine months of the fiscal year, group revenues climbed 6% to €1.6 billion. Yet European and other markets remain hesitant, and no dividend will be proposed at the upcoming annual general meeting. The final audited results for 2025/26 are due in June, when Heidelberg will also present its outlook for the new year. That report will show whether the packaging pivot and the defence venture can gain enough traction to compensate for the softer core business — or whether the margin weakness is becoming structural.
