Adtran Networks SE Reports Q4 2025 Financial Performance

Adtran Networks SE, a prominent supplier of open networking solutions, disclosed its unaudited financial results for Q4 2025. The company announced a 9.5% year-over-year increase in quarterly revenues to EUR 130.2 million, driven by continued demand for its high-performance optical transport solutions amid network modernization and rising bandwidth needs.

The pro forma gross profit for Q4 2025 remained stable at EUR 46.6 million. However, this corresponded to 35.7% of revenues, indicating a margin decline due to product mix and a one-time effect in the previous year.

Pro forma EBIT showed significant improvement, rising to EUR 4.0 million, reflecting enhanced revenues and operational efficiencies. This increase equates to 3.1% of revenues, up from 2.4% in Q4 2024. The company's full annual report for FY 2025 is set for release on March 30, 2026.
