+25%: strong growth in Q1 2026 turnover

+25%: strong growth in Q1 2026 turnover

First-quarter (Q1) 2026 turnover amounts to 133.3 million euros, showing a strong increase, driven by Energy Sales and the intensification of Renvolt’s activity

• Energy Sales: 72.0 million euros, up +3% at constant exchange rates. The growth in the portfolio of power plants in operation more than offsets (i) the disposals of power plants completed in 2025¹ and (ii) the temporary reduced availability of certain plants, particularly in French Guiana²

• Renvolt: 54.3 million euros, up sharply by +80% at constant exchange rates, driven by the increase in construction for third-party clients

• Voltalia Hub³: 7.0 million euros, up +4% at constant exchange rates

Operational capacity and production indicators as of 31 March 2026

• Energy production of 1.1 terawatt-hour, broadly stable (-1%)

• Capacity in operation at 2.9 gigawatts, up +17%

• Capacity in operation and under construction at 3.6 gigawatts, up +9%

Continued rollout of the SPRING plan and confirmation of targets for fiscal year 2026

• Clearer structuring of the Group’s core activities into two distinct business lines: Development and Energy Sales to enhance clarity and operational steering

• Confirmation of the 2026 operational and financial targets

Voltalia reiterates its trajectory towards self-financed growth over the 2026 to 2030 period, with the aim of paying a first dividend from 2028.

Voltalia (Euronext Paris, ISIN code: FR0011995588), an international player in renewable energy, today publishes its first-quarter 2026 turnover.

Robert Klein, Chief Executive Officer of Voltalia, states: “The first quarter of 2026 marks the continuation of the trajectory launched in 2025, with turnover growth supported in particular by Renvolt’s commercial acceleration and stable Energy Sales over the quarter. The increase in turnover and capacity in operation reflects the sound execution of our roadmap and enables us to confirm our 2026 operational and financial targets, while continuing to implement, with disciplined execution, the priorities set out under the SPRING plan.”

First-quarter (Q1) 2026 turnover

Turnover for the first quarter of 2026 amounts to 133.3 million euros, up +25% at constant exchange rates, compared with the same period in 2025 (+24% at current exchange rates). Energy Sales accounts for 54%, Renvolt for 41% and Voltalia Hub for 5% of first-quarter 2026 turnover. Geographically, turnover is generated 63% in Europe, 31% in Latin America and 6% in the rest of the world.

REVIEW OF ACTIVITIES⁴

Energy Sales

First-quarter 2026 production amounts to 1,105 GWh, broadly stable (-1%). Despite the disposals of power plants completed in 2025 and a less favourable wind resource in Brazil compared with the first quarter of 2025, this production benefits from the increase in capacity in operation (+17%).

Breakdown of production by region

• In Latin America, production declines by -8% mainly due to (i) lower-than-expected availability at certain wind farms, for which corrective actions are continuing throughout the quarter, and (ii) a lower wind resource than in 2025 over the same period (iii) and Brazilian curtailment

The Brazilian curtailment reaches 113 GWh, i.e. 13% of Brazilian production (9% of Voltalia’s total production over the period), including nearly 70% concentrated in January alone, before a sharp decline from January 21, corresponding to the commissioning of the Special Protection System⁶, in line with the announcement released today regarding the improvement of grid evacuation conditions.

• In Europe, production decreases slightly (-4%), reflecting the combined effect of the disposals of power plants completed in 2025 and lower-than-expected availability, in particular in French Guiana, in a context of ongoing discussions with the insurer⁷ related to the plant.

• In Africa and internationally, production is multiplied by 2.2, driven by the commissioning of new power plants, in particular in South Africa (Bolobedu) and Uzbekistan (Sarimay Solar).

• Helexia production increased (+3%), in Europe and Brazil.

Turnover for the first quarter of 2026 from Energy Sales amounts to 72.0 million euros, up +3% at constant exchange rates (+2% at current exchange rates). This change mainly reflects the increase in capacity in operation (+17%), which offsets (i) the impact of the disposals of power plants completed in 2025 (Carrières des plaines, Canadel and Pagap power plants in France) and (ii) Brazilian production curtailment as well as lower-than-expected availability at certain power plants in French Guiana and Brazil.

Energy Sales turnover is generated 49% in Latin America, 26% in Europe, 17% by Helexia production and 8% in the rest of the world, illustrating the growing geographic diversification of the portfolio of assets in operation and the declining share of Latin America in the contribution.

Renvolt

Turnover for the first quarter of 2026 from Renvolt amounts to 54.3 million euros, up +80% at constant and current exchange rates. It is driven by strong commercial momentum, in particular in the construction business for third-party clients, notably in Ireland, France and Spain (more than 800 MW under construction for third-party clients as of 31 March 2026).

Voltalia Hub

Turnover for the first quarter of 2026 from Voltalia Hub amounts to 7.0 million euros, up +4% at constant and current exchange rates. Growth in maintenance for third-party clients in Brazil offsets the temporary decline recorded in the Helexia Services and Greensolver activities.

NEW ANNOUNCEMENTS

In Brazil, curtailment reduced from late January 2026 following grid improvements⁸

Curtailment amounted to 113 GWh in Q1 2026, compared with 87 GWh in Q1 2025. In January 2026 alone, curtailment reached 70 GWh, compared with 20 GWh in January 2025. This situation reflects the continuation of the constraints observed at the end of 2025, as the system designed to reduce curtailment (the Special Protection System – SPS) was deployed but only became fully operational as of January 21.

Following joint work with the grid operator (ONS), the implementation of a new technical procedure has improved power injection into the grid in the Serra do Mel area, where Voltalia’s plants are located. This improvement resulted in a marked decrease in reliability‑related curtailment from the end of January and is expected to significantly reduce curtailment across the majority of exposed assets in Northeast Brazil.

Clearer organisation of its core Development and Energy Sales activities⁹
As part of the implementation of the SPRING transformation plan, Voltalia is evolving the organisation of its core Development and Energy Sales activities. They are now structured around two distinct and complementary business lines (BL):

• The Development BL, led on an interim basis by Robert Klein, following the departure of Yoni Ammar.

Development is the Group’s growth engine, with a focus on mature projects, aimed at maximising pipeline value by accelerating permitting processes and achieving ready-to-build status, in order to:

• • Supply the Energy Sales business through the construction of selected projects;

  • Create value through the selective disposal of projects under development

• The Energy Sales BL, led by Amaury Neto, is responsible for operational excellence (Asset Management & Performance), with the objective of progressively improving power plant availability and achieving EBITDA margin targets by 2030.

This organisation strengthens the company’s focus on value creation from assets in operation.
The two directors in charge of the two BLs both report to Voltalia’s Chief Executive Officer. Activities are organised into three geographic regions: Europe, Latin America, and Africa and International. It should be noted that country directors remain the representatives in each country for all activities.

Voltalia would also like warmly to thank Yoni Ammar for his contribution to the company’s development. Over the past 12 years. he has held a number of key positions , in particular as Head of Morocco, Director of Financing and M&A activities, and finally as Deputy Chief Executive Officer in charge of Development and Energy Sales.
