Third quarter turnover up +31%

Third quarter turnover up +31%

Q3 2025 turnover increased to 164.7 million euros (+31%), driven by Services

• Energy Sales: Growth in production +6% (to 1.3 terawatt-hours), driven by improved resource levels and growth in operating capacity. Turnover decrease of -13% (-10% at constant exchange rates), mainly penalised by an unfavourable EUR/BRL exchange rate relative to 2024, a curtailment impact on Brazil production, and a price effect due to the end of short-term contracts at high prices (effects of early generation revenues¹), resulting in turnover of 85.2 million euros

• Services to third parties: Strong growth (2.8x) driven by construction of power plants, particularly in Ireland, Spain and the United Kingdom, with a turnover of 79.5 million euros

Production growth of +11% and capacity increase to 3.3 gigawatts as of September 30, 2025

• Energy production up over the first nine months 2025: +11% to 3.6 terawatt-hours, despite Brazilian curtailment² of 651 gigawatt-hours, for a total of 21% of Brazilian production

• Capacity in operation and under construction: +7% at 3.3 gigawatts including 2.6 gigawatts in operation and 0.7 gigawatt under construction

2025 operational and financial objectives in line with forecasts

• Capacity in operation and under construction of around 3.6 gigawatts (+10% compared with 2024) including around 3 gigawatts in operation (+20%) with most of commissioning at the end of 2025

• Production of around 5.2 terawatt-hours (+10% compared with 2024)

• EBITDA between 200 and 220 million euros, combined with a net loss attributable to the group for 2025 second semester greater than that recorded in the first half of 2025

SPRING transformation plan roadmap in progress

• Since the presentation of the SPRING plan roadmap in early September, the company has launched the following actions:

• Disposals of development activities in three countries: Hungary, Slovakia and Mexico. These disposals will allow to value the work of Voltalia's teams on projects under development in these geographies. The transactions are expected to be completed by the second quarter of 2026

• Launch of preparatory work for the sale of the Spanish development platform, including the portfolio of projects under development at various stages of maturity. The objective of completing the sale is set for the summer of 2026

• Awarded mandates to banking and legal partners on several disposal non-core activities planned for 2026

• Launch of the implementation of the subsidiarization of construction and maintenance activities, which should be completed in the first quarter of 2026

Voltalia (Euronext Paris, code ISIN: FR0011995588), an international player in renewable energy, publishes today its 2025 third quarter turnover.

“Voltalia achieved strong growth in the third quarter, with revenue up 31% to 164.7 million euros. This performance was driven by the excellent momentum of third-party Services, whose activity nearly tripled, offsetting the temporary decline in Energy Sales, with several power plants which will be commissioned in the fourth quarter. The SPRING transformation plan is now entering the implementation phase, paving the way for a more agile and efficient organisation. In a global energy environment undergoing profound change, we continue to be fully committed to sustainably strengthen our profitability, increase our operational efficiency and take full advantage of the opportunities offered by the energy transition.”, declares Robert Klein, CEO of Voltalia.

Turnover for the third quarter (Q3)2025 and for the first nine months (9M) 2025

REVIEW OF ACTIVITIES

Turnover for the first nine months of 2025 totals 421.6 million euros, up by +16% and +19% at constant exchange rates, driven by +87% growth in Services for third-party customers. Energy Sales, representing 56% of turnover, and Services representing 44% of turnover. By geographic region, 66% of the 2025 nine first month turnover was generated in Europe, 29% in Latin America and 5% in the rest of the world.

Turnover for third-quarter of 2025 reaches 164.7 million euros, up +31% (+33% at constant exchange rates), driven by the increase in Services for third party customers (2.8x at current and constant exchange rates), which more than compensated the temporary -13% decline in Energy Sales

ENERGY SALES

Turnover for the first nine months of 2025 from Energy Sales amounts to 237.3 million euros, down -11%
(-6% at constant exchange rates), compared with the same period in 2024. The average EUR/BRL exchange rate is 6.32, compared with 5.69 for the same period in 2024.

Production for the first nine months of 2025 reaches 3.6 TWh, up +11% offset by the effect of curtailment in Brazil of 651 GWh, 21% of Brazilian production (15% of total production over the period). Production benefited from growth in capacity in operation (+3%) and better solar and wind resources in Brazil.

Production in the third quarter 2025 reaches 1.3 TWh, compared with 1.2 TWh in the third quarter 2024 (+6%). The rise in production is due to higher resource levels in Brazil and increased operating capacity, notably from Helexia in Europe and Brazil.

Quarterly production analysis by country:

• In Brazil, production increases by +5% due to a better level of resources than in 2024, despite an increase in curtailment in the third quarter of 2025 (383 GWh), above forecasts

• In France, production falls by -18% due to the combined effect of disposals in 2024³ (La Faye power plant), the impact of the fire at the Cacao biomass power plant in French Guiana, and a less favourable solar resource than in the third quarter of 2024

• In the rest of the world, production is up (+10%) due to the combined effect of better resource levels in the Portugal and Albania

• Helexia's production continues its rapid growth (+22%), in all operational geographies

Turnover for the third quarter of 2025 from Energy Sales reaches 85.2 million euros, down -13% (-10% at constant exchange rates). The capacity increase coupled with better resource levels in Brazil did not offset the cumulative unfavourable effects of (i) the EUR/BRL exchange rate, (ii) the curtailment in Brazil, (iii) the price impact in France and Albania, after benefiting from the favourable effects of high prices on early production⁴ in 2024.

SERVICES⁵ 

Turnover for the first nine months of 2025 from third-party Services, totals 184.2 million euros, up +87% at current and constant exchange rates. The Development and Construction segment grows by 2.0x to 161.7 million euros, and the Operation and Maintenance segment by +15% to 22.6 million euros.

Turnover of the third quarter 2025 from third-party Services reaches 79.5 million euros, up 2.8x at current and constant exchange rates.

Development and Construction turnover for third-party customers reaches 72.2 million euros, up 3.4x (at current and constant exchange rates), boosted by the growth in third-party construction activity, which recorded a 4.3x turnover increase (at current and constant exchange rates). Projects currently under construction in Ireland, Spain and the United Kingdom collectively represent more than 900 MW.

Operation and Maintenance turnover for third-party customers reaches 7.2 million euros, down -2% (-1% at constant exchange rates) compared with the third quarter of 2024. Capacity operated on behalf of third parties reached 7.7 GW (up +16%), thanks to new contracts particularly in Ireland, Brazil, Portugal, in addition with Greensolver’s contracts and from positive impact of revamping work in Spain and France.

Quarterly production (Q3) 2025

¹ Early generation: power sales in a short-term contract that precedes the entry into force of the long-term contract. In the case of Karavasta (Albania), the short-term contract was negotiated at a higher price than the long-term contract, such as Sud Vannier (France).
² For a transmission system operator, curtailment implies limiting the transmission, for a given period, of all or part of a power plant's electrical production potential, to maintain the network's stability.
³ December 9, 2024 press release.
⁴ Early generation sales benefiting from electricity sales under a short-term contract that precedes the entry into force of the long-term contract. In the case of Karavasta, turnover in 2024 benefited from a short-term contract with a premium price over the first-half 2025 contract, which in turn benefits from a premium price over the terms of the long-term contract due to enter into force in the second half of 2025.
