Photon Energy N.V.

Monthly Report for November 2025

For the period from 1 to 30 November 2025

1. Summary of Business Highlights in the Reporting Period

1.1 Generation Results of Photon Energy's Proprietary Power Plants

Total electricity generation in November reached 4.4 GWh compared to 5.5 GWh in the same month last year, representing a 20.0% year-on-year (YoY) decline. The lower output was primarily driven by the underperformance of power plants in Romanian (-54.6% below forecasts), related to ongoing testing for conformity certification – a required step in the licensing procedure. This affected the Sarulesti, Aiud, Teius, Faget 3 and Sahateni power plants, with a total capacity of 27.2 MWp. Sarulesti received its license on 7 November. Aiud and Teius have passed conformity certification process and are now awaiting licenses, which should be granted at the next committee meeting. Scheduling of that meeting is beyond the Company's control but is expected to take place in December or, at the latest in, January. The remaining two power plants — Faget 3 and Sahateni (totalling 14.6 MWp) — are currently undergoing testing, with the licensing process expected to be completed in Q1 2026.

Year-to-date electricity generation reached 136.6 GWh, slightly below last year's level of 141.9 GWh, a decrease of 3.8% YoY.

The average specific yield (total generation in the period / average capacity in the period) decreased to 32.5 kWh/kWp, compared to 42.2 kWh/kWp a year earlier, down by 23.0% YoY.

1.2 Average Realised Prices in the Period

Estimated revenues from electricity sales reached EUR 0.8 million in November and EUR 22.6 million year-to-date (YTD). The average realised price across our IPP portfolio increased to EUR 200/MWh in November compared to EUR 177/MWh in October (+13.0% month-on-month, MoM) and EUR 142/MWh a yar ago (+40.8% YoY).

The strongest rebound was recorded in Romania, where prices more than doubled year-on-year, increasing from EUR 50/MWh in November 2024 to EUR 101/MWh. On a month-on-month basis, prices remained fairly stable across all markets.

For details, see section 3: Average Realised Prices by Our Power Plants.

1.3 Successful Completion of Sale of 20.4 MWp Domanowo Project

In December, Photon Energy N.V. finalized the sale of the 20.4 MWp Domanowo project. The closing took place after all contractual conditions were met, including the project's attainment of full ready-to-build (RTB) status. The transaction was concluded at market value, in-line with comparable renewable-energy asset valuations in Poland. The second and the final payment was executed in Q4 2025, and the financial gain from that transaction will be recognized in the Company's results for the relevant reporting period.

This divestment is fully aligned with Photon Energy Group's strategic priority to optimize its asset base. Monetizing our development pipeline enables the Group to strengthen its financial position and reinforce its focus on value creation in renewable energy, energy storage, and hybrid solutions. The successful sale of the Domanowo project reflects the strong quality and bankability of our project pipeline.

1.4 Launching Breakthrough PFAS Decontamination Technology

In December, Photon Water Technology s.r.o. ("Photon Water"), a subsidiary of Photon Energy N.V. and a technology leader in PFAS remediation and water-treatment solutions, introduced a breakthrough approach for managing fluorinated firefighting foams (AFFF), which contain perfluorinated and polyfluorinated compounds, known as PFAS. The newly developed mobile unit enables on-site decontamination and is capable of treating not only rinsing waters but also the AFFF foam concentrate itself.

This capability marks a significant departure from existing practice, in which AFFF must be handled as hazardous waste, transported to incineration plants and processed in specialised facilities — a costly, administratively demanding and logistically complex procedure for waste-management and remediation firms.

Photon Water's technology is transported directly to the location where AFFF is stored or handled. At the site, the system decontaminates the foam and reduces its volume to a small PFAS concentrate fraction that can subsequently be processed using standard disposal methods at significantly lower cost.

Key benefits of the new technology, among others, include: minimal off-site transport of hazardous AFFF, substantial reduction in disposal and incineration costs, greatly reduced administrative burden and 99.9% efficiency confirmed by independent laboratory testing.

The launch of the technology coincides with major regulatory changes in Europe. On 3 December 2025, the European Union's final derogation for the use and storage of AFFF foams expires. This deadline establishes a clear legislative obligation for holders of these fluorinated foam concentrates to ensure safe decontamination of both the foams themselves and associated systems and infrastructure. Similar regulations have already been in place for several years in Australia, and comparable requirements are expected to be introduced in the United States, Japan, Taiwan, South Korea and other jurisdictions implementing new PFAS-management standards.

Photon Water is therefore introducing its new technology at a critical time, providing partners with an efficient means of responding to these emerging legislative requirements.

This modular setup enables rapid deployment in various field conditions and ensures stable, long-term operation.

The innovation builds on Photon Water's experience with PFASremoval technologies successfully deployed in 2025 across industrial operations for the treatment of process water and PFAS-impacted stormwater. It complements the broader portfolio of Photon Water's innovative, field-proven PFASremediation technologies and further strengthens the company's position as a technological leader in this rapidly expanding sector.
