Q2 2025 turnover

Q2 2025 Energy production +13%

and turnover up +11%

Q2 2025 turnover at 147.7 million euros

• Energy Sales: Growth in production +13% (to 1.3 terawatt-hours) despite a higher curtailment in Brazil. Turnover decrease of -13% (-7% at constant exchange rates), mainly penalised by a price effect arising from the end of short-term contracts at high prices (effects of early production¹), and by an unfavourable EUR/BRL exchange rate relative to 2024, resulting in turnover of 81.7 million euros
• Services to third parties: Strong growth driven by construction of power plants, particularly in Ireland, Spain and the United Kingdom, combined with growth in Operation and Maintenance, increasing Services turnover to 65.9 million euros. Turnover have been restated for the Equipment Procurement segment, which was discontinued in the first half of 2025²

Operational indicators of production and capacity as of June 30, 2025

• Energy production up in the first half of 2025: +14% to 2.4 terawatt-hours, despite Brazilian curtailment³ of 268 gigawatt-hours, for a total of 14% of Brazilian production (10% of total production)
• Capacity in operation and under construction: +7% at 3.3 gigawatts including 2.5 gigawatts in operation and 0.8 gigawatt under construction
• Capacity operated for behalf of third-party clients: +20% to 7.7 gigawatts

2025 operational objectives

• 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)

SPRING Transformation Plan: update on the diagnostic 

• The diagnostic phase is now finalised as of June 2025 – remains the definition of the current action, which will be presented jointly with the presentation of the 2025 half-year results

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

« Voltalia continues to grow in the first half of the year with an increase in turnover, driven by our Services activities, which mitigated the temporary downturn in Energy Sales. This momentum, combined with a 14% increase in production and a portfolio of operating power plants totalling 3.3 gigawatts, reflects our solid underlying operating indicators. In line with our business activities, we are finalising our SPRING strategic plan, whose actions will be presented in September for immediate implementation, with the aim of strengthening our competitiveness and agility in the face of the sector’s swift evolution. In this rapidly changing renewable energies market, Voltalia is fully mobilized to transform these challenges into levers for sustainable and profitable growth.", declares Robert Klein, CEO of Voltalia.

Second-quarter (Q2) and first-half 2025 turnover

REVIEW OF ACTIVITIES

First-half 2025 turnover reaches 257 million euros, up +9% at current exchange rates (+13% at constant exchange rates). Whilst Energy Sales were down -9% at current exchange rates, growth was driven by Services to third parties, which were up by 50% at current exchange rates (+50% at constant exchange rates). Energy Sales and Services account for 59% and 41% respectively of first-half 2025 turnover. By geographic region, 64 % of half-year turnover was generated in Europe, 30% in Latin America and 6% in Africa.

Second-quarter 2025 turnover reaches 147.7 million euros, up +11% (+16% at constant exchange rates), driven by the +69% increase in Services for third party customers (+70% at constant exchange rates), which mitigated the temporary -13% decline in Energy Sales. Energy Sales and Services account for 55% and 45% respectively of second-quarter 2025 turnover.

ENERGY SALES

First-half 2025 turnover from Energy Sales reaches 152.1 million euros, down -9% (-2% at constant exchange rates). The average EUR/BRL rate was 6.30 in the first half of 2025, compared with 5.49 in the first half of 2024.

Second-quarter 2025 production reaches 1,257 GWh, up +13% compared with second-quarter 2024 from 1,111 GWh. The rise in production is due to higher resource levels in Brazil and increased operating capacity, notably from Helexia in Europe and Brazil. Operating capacity is 61% in Latin America, 36% in Europe and 3 % in the rest of the world.

Quarterly analysis production by country

• In Brazil, production increases by +17% due to a better level of resources than in 2024, despite an increase in curtailment in the second quarter of 2025 (181 GWh).
• In France, production falls by -20% due to the combined effect of disposals in 2024⁴ and a less favourable solar resource than in the second quarter of 2024.
• In the rest of the world, production is up +3% due to the combined effect of better resource levels in the United Kingdom and Albania, and new capacity commissioned in Italy.
• Helexia's production continues its rapid growth (+31%), in Europe and Brazil.

Second-quarter 2025 turnover from Energy Sales reaches 81.7 million euros, down -13% (-7% at constant exchange rates). The capacity increase coupled with better resource levels in Brazil did not offset the cumulative unfavourable effects of (i) the price impact in France and Albania, in which Voltalia benefited in 2024 from the favourable effects of high prices on early production⁵, (ii) the EUR/BRL exchange rate and (iii) curtailment in Brazil.

SERVICES⁶ 

First-half 2025 turnover from third-party Services reaches 104.8 million euros, up +50% (+50% at constant exchange rates). The Development and Construction segment grew by +55% to 89.5 million euros, and the Operation and Maintenance segment by +26% to 15.3 million euros. To be noted that in the first half of 2025, Voltalia initiated the winding down of its Equipment Procurement business segment. First-half 2025 turnover and second quarter 2025 turnover (as well as comparative periods) have been restated for the discontinued Equipment Procurement business segment⁷.

Second quarter 2025 turnover from third-party Services reaches 65.9 million euros, up +69% (+70% at constant exchange rates).

Third-party Development and Construction turnover reaches 57.8 million euros, up +79% (at current and constant exchange rates), boosted by the growth in third-party construction activity, which recorded a +65% turnover increase (at current and constant exchange rates). Projects currently under construction in Ireland, Spain and the United Kingdom collectively represent more than 800 MW.

Operation-Maintenance turnover for third-party customers reaches 8.1 million euros, an uplift of +23% (+26% at constant exchange rates) compared with the second quarter of 2024. Capacity operated on behalf of third parties reached 7.7 GW (up +20%), thanks to new contracts particularly in Portugal and Brazil.

RECENT ANNOUNCEMENTS

Update on the Brazilian power grid

Curtailment in Brazil during the first half of the year amounted to 268 GWh (i.e. 14% of Brazilian production and 10% of total production over the period). It was higher than the half-year estimates. During the presentation of its 2024 annual results, Voltalia stated that its 2025 operating targets included an assumption of 10% curtailment in 2025 in Brazil⁸  (compared with 21% in 2024).

A Working Group (WG) set up by the Comité de Surveillance du Secteur Électrique (CMSE) to limit curtailment’s impact, is pursuing its actions. As a result, the ONS (Opérateur National du Système Électrique) has enabled the transmission of a greater volume of energy. The aim is to exploit wind generation to a greater extent, thereby reducing curtailments and the use of thermal power plants.

Voltalia remains confident of a favourable outcome, in the medium term, to the legal and contentious actions undertaken for compensation, however, given this evolving context, no compensation has been included for 2025.

Update on the Cacao power plant

On April 29, 2025, a sawmill adjacent to the Cacao biomass plant (Cacao Biomasse Énergie) in French Guiana caught fire. Although the smoke detection and fire protection systems were functioning correctly, the fire severely damaged the sawing line (not owned by Voltalia S.A) and the two biomass feed conveyors.

Following the incident, technical and industrial assessments have been carried out to precisely evaluate the options to limit the impact on plant operations. Based on these analyses, the plant is expected to be out of operation for an estimated six to twelve months, which could represent a potential loss of around 6 million euros in turnover by 2025, excluding recourse to third parties, including insurance companies, which are currently being analysed.

SPRING TRANSFORMATION PLAN: UPDATE ON THE STRATEGIC BUSINESS REVIEW

The diagnostic phase of the SPRING transformation plan, initiated at the beginning of 2025 by the new general management, was finalised in June, as previously announced⁹. An action plan is currently being drawn up, aimed at creating sustainable conditions for profitable growth in line with the company's mission.

The conclusions of this initial phase will be presented at the time of the half-yearly results, along with the roadmap for implementing the diagnostic recommendations. Expected to have an initial impact as early as 2025, this roadmap will serve as a guide to ensure effective, structured implementation of the recommended actions.

SPRING is thus a strategic lever for strengthening Voltalia's sustainable and profitable growth trajectory, based on a clearer organisation focused on value creation.

2025 OPERATIONAL TARGETS

Voltalia confirms its operating targets for 2025:

• Approximately 3.6 gigawatts of capacity in operation and under construction (+10% compared with 2024), of which approximately 3 gigawatts in operation (+20%), with the majority commissioned by the end of 2025
• Production of around 5.2 TWh (+10% compared with 2024), including a 10% curtailment assumption in Brazil (compared with 21% in 2024)

UPCOMING EVENTS

• Half-Year Results 2025 and SPRING transformation plan presentation, on September 4, 2025 (before trading) followed by a 10am (CET) in-person event with live webcast

Capacity in operation as of June 30, 2025

Capacity under construction as of June 30, 2025

Production as of June 30, 2025

Quarterly production (Q2) 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 During the first half of 2025, Voltalia initiated the discontinuation of its Equipment Procurement business. At the end of June 2025, the criteria for qualification as a “discontinued operation” within the scope of IFRS 5 were fulfilled. Consequently, turnover for 2025 and 2024 have been restated for the Equipment Procurement business.

³ 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.

⁴ December 9, 2024 press release.

⁵ 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.

⁶ Services: Third-party services.

⁷ In accordance with IFRS 5.
