Adtran Networks SE: Adtran Networks SE updates guidance for the financial year 2025

Munich, Germany. November 4, 2025. The Management Board of Adtran Networks SE today reassessed the earnings expectations for the financial year 2025 and adjusted its expectations.

In its published guidance for the financial year 2025, the Management Board assumed that the pro forma EBIT might grow from a negative single-digit percentage in 2024 to a positive single-digit percentage in 2025.

On the basis of today’s review, the Management Board expects that the earnings guidance should change and anticipates a pro forma EBIT in relation to revenue in a low negative to low positive single digit percentage mainly due to timing of shipments during the fourth quarter.

According to the Domination and Profit and Loss Transfer Agreement between Adtran Holdings, Inc. and Adtran Networks SE, Adtran Networks SE is obligated to transfer any annual profit to Adtran Holdings, Inc. and Adtran Holdings, Inc. is obligated to compensate any annual losses of Adtran Networks SE. The adjustment of the pro forma EBIT range does not affect the annual compensation payment to the outside shareholders.

As planned, the financial results for Q3 2025 will be published separately today, and the interim statement on November 12, 2025.

The glossary of the financial reports published on the company website (www.adva.com) contains a definition of pro forma EBIT.
