Heidelberg Druck Sets Course for June 10 as Defence Pivot and Margin Squeeze Converge

Heidelberg stock rebounds after 30% drop but profit margin miss clouds outlook. Defense venture ONBERG targets critical infrastructure, yet commercial wins pending.

Heidelberger Druckmaschinen enters the final stretch before its audited annual results on 10 June with a share price that has clawed back some ground but remains under a cloud. After shedding more than 30% from an April peak of just over €2, the stock has found support around €1.32 — a level that has triggered reversals several times before. On Wednesday the shares jumped 7.5% to €1.57, taking the weekly gain to roughly 14.5%. Friday saw the stock trade between €1.49 and €1.54, a session that looked more like consolidation than a decisive breakout.

The chart tells a cautious story. As long as €1.30 holds as weekly support, the technical picture stays constructive. A sustained move above €1.45 would open the door towards the €1.60 area. A weekly close below €1.30, however, would risk a slide back towards the €1.00 mark.

Margin Miss Undermines a Solid Top Line

The preliminary figures already flagged a miss on profitability. Adjusted EBITDA margin for the 2025/26 financial year is expected to land at roughly 6.6%, below the original guidance of 7.1%. Management has pointed to four factors: accelerated spending on the new defence business, a sharp drop in customer investment appetite triggered by the Iran conflict from late February 2026, an unfavourable product mix and currency headwinds. Despite those pressures, Heidelberg still managed to hit its revenue target on a constant-currency basis.

The balance sheet offers some reassurance. The company closed the year with a positive net financial position of approximately €39 million. Banks have extended the credit line early through to 2030, and no dividend will be paid as capital is channelled into growth and balance-sheet strengthening.

Defence: Small Scale, High Hopes

The defence segment currently contributes less than 2% to group revenue, though order intake in the unit has risen 6% in the latest period. On 14 April 2026, the joint venture ONBERG Autonomous Systems began operations in Brandenburg an der Havel. The venture brings together Heidelberg’s subsidiary HD Advanced Technologies and US-Israeli Ondas Autonomous Systems to build an integrated drone-defence business — from development to series production, with systems being tested in both Germany and Ukraine under real-world conditions.

Regulatory tailwinds are building. Germany’s new KRITIS umbrella law will require roughly 2,000 critical infrastructure sites to upgrade their protection measures. ONBERG is targeting exactly that market, from military facilities to industrial parks and transport hubs. The problem is that the venture remains in the demonstration phase; concrete contract wins have yet to materialise. The 10 June annual report will offer the first detailed financial breakdown of the defence unit, which the market will scrutinise for any signs that the pivot from cyclical printing is gaining commercial traction.

Leadership Locked In

The board has signalled its confidence in the strategic direction by extending CEO Jürgen Otto’s contract through July 2029 and CSO Dr David Schmedding’s through June 2031, both effective from 1 July 2026. That gives management runway to see the defence gamble through — but the next few quarters will determine whether the market gives it the benefit of the doubt.
