Contents of the report:

The Management Board of Photon Energy N.V. announces that the quarterly coupon payment for the Photon Energy N.V. Green Bond 6,5% 2021/2027 [ISIN: DE000A3KWKY4; WKN: A3KWKY] due on 23 February 2026 in the amount of EUR 1.282.450 has been postponed.

The Management Board decided to postpone the coupon payment in order to conserve liquidity in the light of the most recent developments in relation to its dispute with the Polish transmission system operator PSE (see ESPI report 5/2026), where PSE has informed the Company about its intention to commence a unilateral offset of revenues due on 2 March 2026 with the disputed amount related to the alleged breach of emission limits on Capacity Market units in 2024.

The Management Board regrets this situation and is actively working on resolving this matter through the legal process and on securing sufficient liquidity to meet the Company’s interest payment obligations towards its bond holders as soon as possible.
