2025 turnover up +16% at constant exchange rates

2025 turnover up +16% at constant exchange rates

2025 EBITDA target reconfirmed despite curtailment impact

Continued rollout of the SPRING transformation plan

Fourth‑quarter (Q4) 2025 turnover at 166.3 million euros (+8% at constant exchange rates)

• Energy Sales: Turnover amounts to 78.5 million euros, down -15% at constant exchange rates, mainly impacted by higher‑than‑expected curtailment in Brazil, a price effect resulting from the end of short‑term contracts previously signed at high price levels¹, and a less favorable EUR/BRL exchange rate
• Services for third‑party clients²: Turnover totals 87.8 million euros, up +42% at constant exchange rates, driven by the combined performance of Construction for third‑party clients (+43%) and Operation & Maintenance (+18%)

Achievement of the operating and construction capacity target

• Capacity in operation and under construction of 3.6 gigawatts, representing +9% growth
• Capacity in operation of 2.9 gigawatts, up +16%, driven by 408 megawatts commissioned, more than 75% connected during the fourth quarter
• Capacity under construction at 0.6 gigawatt, following the start of construction of 305 megawatts in 2025

2025 production up +4% despite higher curtailment in Brazil

• Energy production reached 4.9 terawatt-hours, compared with an initial forecast of around 5.2 terawatt-hours, and was split 51% wind, 47% solar, with the remainder coming from other technologies. It should be noted that major commissioning milestones took place at the very end of the year and will contribute to operational results starting in 2026
• Energy production in Brazil increased by +2%, despite curtailment levels exceeding expectations. Curtailment reached 1,040 gigawatt-hours, up +19% vs. 2024, representing 23% of Brazil’s 2025 production (compared with an initial assumption of 10% for the year)
• As announced³ , Law No. 15,269, passed in Brazil in November, provides for the reimbursement of compensation⁴ related to reliability‑based curtailment events that occurred between September 2023 and November 2025, which account for a significant share of total curtailment for Voltalia. Following discussions and analysis, this compensation is estimated at over 20 million euros, although some implementation modalities still need to be finalized. Regarding future curtailment, discussions with authorities are ongoing concerning the mechanisms to be applied, particularly those relating to curtailment caused by supply–demand balances

Confirmation of the 2025 EBITDA Target

• EBITDA between 200 million euros and 220 million euros, of which 190 million euros to 210 million euros from Energy Sales
• A Group net accounting loss in the second half of the year exceeding that recorded in the first half of 2025, mainly due to potential impacts related to: (i) the acceleration of pipeline cleanup, (ii) transformation and restructuring costs linked to the SPRING program, and (iii) the effects of geographical refocusing and the strengthened emphasis on core activities

SPRING transformation plan: Deployment phase underway

Since the presentation of the SPRING plan roadmap in early September, and in line with the plan, the company has launched the following initiatives:

• Geographical refocusing: Disposal of development activities in four countries (Slovakia, Hungary, Mexico, and Spain), with Romania⁵ now added to the list
• Technological refocusing: Confirmation of the discontinuation of biomass and small hydro project development, along with the announcement of the cessation of new green hydrogen project development
• Divestment of non‑strategic activities: Progress in line with the roadmap
• Strengthening of governance and the operating model:
  • Completion of the creation of Renvolt, which brings together Construction and Operation & Maintenance services
  • Appointment of the new Chief Executive Officer of Renvolt and the new Chief Executive Officer of Helexia

Voltalia (Euronext Paris, ISIN code: FR0011995588), an international player in renewable energy, today publishes its turnover for the fourth quarter of 2025 and for the full year 2025.

“In 2025, despite a higher-than-expected level of curtailment in Brazil, we recorded further growth in our turnover and confirmed our EBITDA target, illustrating the resilience of our business model. The validation of the law in Brazil, which confirms the reimbursement of compensation related to past curtailments, represents a significant step forward for Voltalia, while discussions are ongoing regarding the mechanisms applicable to future periods. At the same time, the deployment of the SPRING plan is progressing in line with our roadmap: we are simplifying our scope, clarifying our organization, and focusing our resources on the activities that create the most value. These structural decisions aim to sustainably strengthen our performance and prepare the next phases of the company’s development,” says Robert Klein, Chief Executive Officer of Voltalia.

Fourth quarter (Q4) and 2025 full year turnover

ACTIVITY REVIEW

Turnover for 2025 reaches 587.8 million euros, up +16% at constant exchange rates (+13% at current exchange rates), driven by the strong growth of Services for third-party clients, which rises +70% at constant exchange rates (+69% at current exchange rates). Energy Sales and Services for third-party clients accounts for 54% and 46% of total turnover, respectively.

Geographically, 2025 turnover is distributed as follows: 67% in Europe, 29% in Latin America, and 4% in the rest of the world.

Turnover for the fourth quarter of 2025 totals 166.3 million euros, up +8% at constant exchange rates (+7% at current exchange rates). Growth of the Development and Construction segment for third‑party clients more than offset the impact of lower production due to curtailment in Brazil. Energy Sales declines -15% at constant exchange rates (-16% at current exchange rates), while Services for third‑party clients increases +42% at constant exchange rates (+41% at current exchange rates) compared with 2024.

ENERGY SALES

Turnover in 2025 from Energy Sales totals 315.8 million euros, down -8% at constant exchange rates (-12% at current exchange rates) compared with the same period in 2024.

Production in 2025 reaches 4.9 TWh, up +4%, but below the initial forecast of around 5.2 TWh, due to the impact of curtailment in Brazil totaling 1,040 GWh, representing 23% of Brazilian production (17% of total production over the period).
This production level reflects the growth in installed capacity (+16%) as well as improved solar and wind resources in Brazil. To be noted, the main commissioning occurred at the end of the year and will contribute in 2026.

Fourth‑quarter 2025 production reaches 1.3 TWh, compared with 1.4 TWh in the fourth quarter of 2024, representing a -11% decline.

Quarterly production analysis by country:

• Brazil: Production falls -17% due to a sharp increase in curtailment in Q4 2025 (up 2.3x to 389 GWh), despite better solar and wind resource levels
• France: Production decreases -4%, driven by a combination of (i) asset disposals in 2024⁷ (La Faye plant), (ii) the impact of the fire at the Cacao biomass plant in French Guiana (covered by an insurance policy) and (iii) less favorable solar resource compared with Q4 2024, partly offset by better wind conditions

• Rest of the world: Production grows by +16% notably thanks to new plants commissioned
• Helexia: Production continues to grow strongly (+20%) across all geographies

Fourth‑quarter 2025 turnover from Energy Sales amounts to 78.5 million euros, down -15% at constant exchange rates (-16% at current exchange rates). The increase in capacity, combined with improved resource levels in Brazil, was not sufficient to offset the unfavorable effects of: (i) curtailment in Brazil, (ii) pricing impacts in France and Albania after benefiting from high price levels on initial 2024 production⁸, and (iii) the EUR/BRL exchange rate impact.

SERVICES⁹ 

Turnover in 2025 from Services for third‑party clients amounts to 272.0 million euros, up +70% at constant exchange rates (+69% at current exchange rates). The Development and Construction segment grows +78% at both constant and current exchange rates, reaching 244.9 million euros, while the Operation & Maintenance segment increases +18% at constant exchange rates (+15% at current exchange rates) to 27.1 million euros.

Turnover for the fourth quarter of 2025 from Services for third‑party clients totals to 87.8 million euros, up +42% at constant exchange rates (+41% at current exchange rates).

Turnover from the Development and Construction segment for third‑party clients reaches 83.3 million euros, representing an increase of +43% at both constant and current exchange rates. Ongoing construction projects, particularly in Ireland and Spain, account for a combined capacity of around 900 MW.

Turnover from the Operation & Maintenance segment for third‑party clients totals 4.5 million euros, up +18% at constant exchange rates (+15% at current exchange rates) compared with the fourth quarter of 2024. The capacity operated on behalf of third‑party clients reaches 8.7 GW (+34%), driven by the full‑year impact of new contracts in France, Ireland, and Brazil.

NEW ANNOUNCEMENTS

In Brazil: reflecting a law on the compensation of past curtailment linked to the reliability of the network¹⁰

Voltalia welcomes the adoption in Brazil of Law No. 15.269 last November by President Lula, which reimburses a significant part of past compensation related to reliability curtailment (excluding curtailment related to the balance of supply and demand).

The measure covers the period from September 1, 2023 to November 24, 2025 and, following discussions and analysis,

would represent more than 20 million euros for Voltalia (indexed to the IPCA), with calculations made by the ONS (Operador Nacional do Sistema Elétrico – Brazilian grid operator) and ANEEL (Agência Nacional de Energia Elétrica – electricity regulator in Brazil) according to terms that are still being finalized.

The company is currently assessing the accounting treatment of these items, the impact of which is expected to materialize mainly in 2026 and 2027, while discussions continue with the authorities on mechanisms for future curtailment, including those related to the balance of supply and demand, to improve visibility and regulatory stability for the broader market.
