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

"Voltalia had a resilient start to the year with a slight increase in revenue of +2% to 113 million euros. The solid performance of Services offset the temporary decline in Energy Sales. In this segment, our teams remain fully mobilized to achieve our operational objectives, i.e. 3.6 gigawatts in operation and construction and 5.2 terawatt hours of production. In addition, the diagnostic phase of the SPRING transformation plan is underway and should be completed, as planned, in June. In a rapidly evolving renewable energy sector, we are fully mobilized to improve our sustainable profitability while strengthening the company's operational agility, in order to fully seize the opportunities that lie ahead," comments Robert Klein, Chief Executive Officer of Voltalia.

¹ Early generation: sales of electricity under a short-term contract that precedes the long-term contract. The short-term contract was concluded at higher prices than the long-term contract in the case of Karavasta (Albania) and Sud Vannier (France). 2 January 29, 2025 press release.

REVIEW OF ACTIVITIES

Turnover amounts to 113.3 million euros, up +2% compared to the first quarter of 2024 (+7% at constant exchange rates), driven by strong growth of +19% in Services for third-party clients at current and constant exchange rates, which offset the temporary decline in Energy Sales at -6% (+1% at constant exchange rates), mainly due to a price impact on 2024 as previously announced (Albania and France). Energy Sales contributed 62% and Services 38% of the turnover in the first quarter of 2025. Geographically, turnover is generated at 60% in Europe, 35% in Latin America and 5% in Africa.

Production (in GWh)	1,121	973	+15%

Capacity in operation (in MW)	2,517	2,407	+5%
Capacity in operation and under construction (in MW)	3,279	2,928	+12%
Wind load factor in Brazil	33%	28%	+5pts

Solar load factor in France	10%	12%	-2pts
Solar load factor in Egypt and Jordan	22%	21%	+1pt
Solar load factor in Albania	13%	15%	-2pts

Production reaches 1,121 GWh, compared to 973 GWh in the first quarter of 2024, up +15%. The increase in production is driven by better resource levels in Brazil and higher capacity in operation, notably from Helexia in Europe and Brazil. Capacity in operation is located at 61% in Latin America, 36% in Europe and 4% in the rest of the world.

³ The calculation of load factors is done at comparable perimeters. The calculation of load factors for 2024 does not include the plants that were sold during the year 2024.

Production analysis by country

• In Brazil, production increases by +16% due to a better level of resources than in 2024. The Brazilian production curtailment in the first quarter of 2025 is 87 GWh (10% of Brazilian production for the quarter). For the record, Voltalia has forecasted a 10% curtailment of its Brazilian production in 20254 .
• In France, production falls by -14% due to the combined effect of disposals in 2024⁵ and a less favourable solar resource than in the first quarter of 2024.
• In the rest of the world, production is down slightly by -5% due to a lower resource in Portugal and Albania. As a reminder, production in Q1 2024 had been multiplied by 2.0x compared to Q1 2023.
• Helexia's production continues its rapid growth (+92%), in Europe and Brazil.

Turnover from Energy Sales reaches 70.4 million euros in the first quarter of 2025, down slightly by -6% (+1% at constant exchange rates). The increase in capacity coupled with the better resource levels in Brazil did not offset the cumulative unfavourable effects of (i) the price impact in France and Albania, where Voltalia benefited in 2024 from the favourable effects of high prices on early generation⁶ , (ii) the EUR/BRL exchange rate and (iii) curtailment in Brazil.

Services⁷

In million euros	Q1 2025	Q1 2024	Var. at current exchange rates	Var. at constant exchange rates
Turnover from Development, Construction and Equipment Procurement	35.7	30.2	+18%	+18%
Turnover from Operation and Maintenance	7.2	5.9	+22%	+24%
Total Turnover from Services	42.9	36.1	+19%	+19%

Turnover from Services for third-party clients amounts to 42.9 million euros, up sharply by +19% at current and constant exchange rates.

• Turnover from the Development, Construction and Equipment Procurement segment for third-party clients amounts to 35.7 million euros (+18% at current and constant exchange rates), driven by the strong growth in turnover generated by the construction activity for third-party clients (+33%), particularly in Ireland for more than 460 MW (Ørsted, ESB and Power capital), Spain for 135 MW (Green Arrow) and in the United Kingdom for 60 MW (Alpha Real).
• Turnover from the Operations and Maintenance segment for third-party client reaches 7.2 million euros, a +22% growth (+24% at constant exchange rates) compared to the first quarter of 2024. Capacity operated on behalf of third parties reaches 7.5 GW (+50%) benefiting from new contracts in Spain (Olivares, Los Llanos, Manzanares) and Brazil (Arinos and Vila Acre).

⁴ March 13, 2025 press release: a 10% curtailment assumption is considered for 2025 (vs. 21% in 2024).

⁵ December 9, 2024 press release.

⁶ Early generation turnover benefiting from electricity sales in a short-term contract that precedes the long-term contract. In the case of Karavasta, the 2024 turnover benefited from a short-term contract at a higher price than the contract for the first half of 2025, which itself also benefits from a higher price than the terms of the long-term contract that will start in the second half of 2025.

⁷ Services: Services for third-party clients.

NEW ANNOUNCEMENT

Update on the situation of the Brazilian electricity grid

The production curtailment in Brazil in the first quarter reaches 87 GWh (10% of Brazilian production and 7% of total production). During the presentation of the 2024 annual results, Voltalia announced that its 2025 operating objectives include a 10% curtailment assumption for Brazil production8 (compared to 21% in 2024).

The Electricity Sector Supervisory Committee (CMSE) has decided to create a Working Group (WG) to reduce curtailment as soon as possible, in particular through the installation of compensators, the deployment of storage systems and the optimization of the network. As early as 2025, an additional 1,800 MW could be transported from the Northeast to the Southeast, thus limiting losses during periods of strong winds.

The Minister of Energy also announced in mid-April 2025 his desire to quickly provide a structural response to the problem of curtailment, including the possibility of compensation measures.

Voltalia remains confident that the legal and litigation actions taken to obtain compensation will be successful in the medium term.

RECENT ANNOUNCEMENT

This ambitious project is co-financed by the European Bank for Reconstruction and Development (EBRD) and aims to equip students with the professional skills needed to thrive in the country's growing renewable energy sector.

SPRING TRANSFORMATION PLAN: UPDATE ON THE STRATEGIC BUSINESS REVIEW

The diagnostic phase of its SPRING transformation plan, initiated in early 2025 by the new management, is underway, as announced10. This plan aims to create the sustainable conditions for profitable growth aligned with the company's mission.

The conclusions of this first phase will be unveiled during the presentation of the half-year results, accompanied by a detailed roadmap for deploying the recommendations resulting from the diagnosis. This roadmap, of which the first benefits are expected as early as 2025, will serve as a guide to ensure an effective and structured implementation of the recommended actions.

SPRING is thus a strategic lever to consolidate Voltalia's sustainable and profitable growth trajectory by 2027, based on a more readable organization focused on value creation.
