Acquisition of Wind Projects in Romania – Entry into the Bulgarian RES Market

Specifically, HELLENiQ ENERGY Holdings S.A. (the “Company”) informs the investment community that:

a) HELLENiQ RENEWABLES ROMANIA S.R.L., a wholly owned subsidiary of HELLENiQ RENEWABLES S.A., itself a wholly owned subsidiary of the Company, has successfully completed the acquisition from OX2 HOLDING NEW MARKETS AB of the entire share capital of ANSTHALL GREEN ENERGY S.R.L., which owns a ready-to-build wind project in the Galati region of Eastern Romania, with a licensed capacity of 96 MW. Construction of the project will start immediately under an agreement with OX2 Construction AB, and the project is expected to become operational in 2027. The project will benefit from secured revenue for 12 years through a virtual PPA with KONINKLIJKE AHOLD DELHAIZE N.V. for more than 50% of its production.

b) HELLENiQ RENEWABLES ROMANIA S.R.L., a wholly owned subsidiary of HELLENiQ RENEWABLES S.A., itself a wholly owned subsidiary of the Company, has signed a binding agreement to acquire the entire share capital of HELIOS & WIND ENERGY S.R.L., which owns a ready-to-build wind project in the Vaslui region of Eastern Romania, with a licensed capacity of 186 MW and an option to add a 186 MW/186 MWh battery energy storage system (BESS). Completion of the transaction is subject to conditions precedent including the approval of the Foreign Direct Investment (FDI) Committee of Romania.

c) HELLENiQ RENEWABLES BULGARIA EOOD, a wholly owned subsidiary of HELLENiQ RENEWABLES S.A., itself a wholly owned subsidiary of the Company, has successfully completed the acquisition from ELEMENT POWER GROUP EOOD of the entire share capital of AGRO NV PROPERTIES EOOD, which owns a ready-to-build photovoltaic project in the Haskovo region of Southern Bulgaria, with a capacity of 123 MWp and an option to add a 90 MW/180 MWh battery energy storage system (BESS). This transaction marks the entry of HELLENiQ ENERGY Group in the rapidly growing Bulgarian RES market.

Furthermore, the commencement of construction for two battery storage projects in Florina, Greece, possessing an aggregate capacity of 50 MW (200 MWh), is anticipated in 4Q25. These projects have been selected through the third tender conducted by the Regulatory Authority for Energy, Waste and Water (RAEWW) to receive investment and operating aid for Energy Storage Systems (ESS).

With these transactions, HELLENiQ ENERGY Group expands its presence in the RES market of Southeast Europe, adding RES projects with a total capacity of over 400 MW. At the same time, it strengthens the geographic diversification of its portfolio and balances the mix across various technologies (wind, photovoltaic, battery energy storage). The above transactions bring the mature and operating RES project portfolio to a combined capacity of approximately 1.5 GW. This represents approximately 75% of the target for 2 GW of installed RES capacity by 2030.

At the same time, with the completion on 30 June 2025 of the acquisition by HELLENiQ RENEWABLES of the share capital of ABO ENERGY HELLAS S.A., as well as of six (6) affiliated companies holding a portfolio of RES projects under development in Greece of a total capacity of 1.5 GW, and a platform for the development and construction of RES projects, the total RES project portfolio under development is strengthened to over 6 GW, accelerating the achievement of strategic objectives.
