Heidelberger Druckmaschinen Aktiengesellschaft: HEIDELBERG adjusts earnings forecast for the 2025/2026 financial year

Heidelberg, April 15, 2026 / 17:59 CEST

Based on preliminary, as of yet unaudited figures, Heidelberger Druckmaschinen AG (HEIDELBERG) expects to close the 2025/2026 financial year, which ended on 31 March 2026, with an EBITDA margin adjusted for special items of approximately 6.6%. The previous forecast had anticipated an improvement in the adjusted EBITDA margin compared with the prior year (7.1%).
HEIDELBERG has therefore adjusted its earnings forecast for the 2025/2026 financial year accordingly. The adjustment is based on the interim results currently available in the course of the ongoing preparation of the consolidated financial statements. The reasons for the adjustment are as follows:

• Expenses brought forward in time for new business areas outside the core business, in particular due to the successful market entry in the defense sector;
• A renewed and abrupt significant weakening of investment appetite, inter alia as a consequence of the Iran conflict that began in late February 2026;
• An unfavorable product mix that continued into the fourth quarter of the 2025/2026 financial year;
• Sequentially unchanged currency effects, which continue to have a negative impact.

According to preliminary figures, the revenue target for the 2025/2026 financial year is expected to be achieved on a currency-adjusted basis, and the order intake was also able to continue the trend seen in the final quarters of previous years.

HEIDELBERG will publish the final, audited financial results for the 2025/2026 financial year on June 10, 2026.
