+35% growth in Q2 2026 turnover driven by new capacity, notably in South Africa and Uzbekistan

Turnover of 198.0 million euros in Q2 2026

Energy Sales: 118.2 million euros, up +40% at constant exchange rates. Growth is driven by the contribution from new capacity commissioned at the end of 2025, favourable price effects and the recognition in the first half of the year of compensation related to production curtailment in Brazil (17 million euros impact on turnover¹). These factors offset temporarily lower-than-expected availability in French Guiana, linked to the still gradual restart of the Cacao power plant², as well as in Brazil³, where production was affected by a less favourable wind resource. Production curtailment in Brazil continues to decrease in volume compared with the previous year, while still representing 14% of Brazilian production
Renvolt: 69.6 million euros, up +26% at constant exchange rates, driven by continued commercial momentum in both construction and maintenance for third-party clients
Voltalia Hub: 10.2 million euros, up +35% at constant exchange rates, supported by growth in Helexia Services and maintenance activities in Brazil

Operational capacity and production indicators as of June 30, 2026

Energy production of 2.4 terawatt-hours, up +1%
Capacity in operation at 3.0 gigawatts, up +17%
Capacity in operation and under construction at 3.6 gigawatts, up +9%

Continued execution of the SPRING plan and confirmation of 2026 financial objectives

Continued implementation of the SPRING plan, with an organisation refocused on core activities, strengthened discipline in capital allocation and continued improvement in operational performance
All actions undertaken will be presented when the half-year 2026 results are published on 3 September 2026
Continued discussions relating to disposals of non-strategic assets and activities, as part of the objective of 300 to 350 million euros in cash inflows, the majority of which is expected by the first half of 2027
Operational and financial objectives for 2026
- Voltalia confirms its 2026 financial objectives, with EBITDA of between 210 and 230 million euros, including 190 to 210 million euros generated by the Energy Sales business, and a positive net result
- Regarding its operational objectives, as part of its strengthened approach to operational and financial discipline, Voltalia is reviewing the phasing of the launch of construction of certain projects. This selective review leads to a revised 2026 total capacity objective of 3.6 GW⁴ instead of around 3.7 GW, while strictly maintaining the Group’s annual financial objectives.

Voltalia (Euronext Paris, ISIN code: FR0011995588), an international player in renewable energy, today publishes its turnover for the second quarter of 2026.
Robert Klein, Chief Executive Officer of Voltalia, states:

“The second quarter of 2026 confirms the momentum initiated since the start of the year, with turnover increasing sharply, driven by all our Business Units. In a context marked by a less favourable wind resource in Brazil and a level of curtailment that remains significant, our operational indicators are improving, with half-year production slightly up and capacity in operation now close to 3 gigawatts. In addition, the recognition in the first half of the year of financial compensation related to production losses resulting from curtailment between September 2023 and November 2025⁵ represents an important step forward for the Group. Beyond these positive developments, we continue to execute our SPRING roadmap with discipline.”

Second-quarter 2026 production amounts to 1,303 GWh, up +4% compared with the second quarter of 2025. Over the first half of 2026, production reaches 2,408 GWh, up +1%, benefiting from the contribution of new power plants commissioned, notably in South Africa and Uzbekistan, as well as from Helexia’s growth, despite lower production in Brazil. Brazilian production curtailment represents 105 GWh in the second quarter of 2026, down -42% compared with the second quarter of 2025.

Breakdown of production by region

In Latin America, production declines by -17%, mainly reflecting a less favourable wind resource in Brazil and lower-than-expected availability at certain power plants. Curtailment decreases in volume, to 105 GWh in the second quarter of 2026 compared with 181 GWh in the second quarter of 2025. It represents 14% of Brazilian production and 7% of total production in the second quarter, in a context of lower Brazilian production.
In Europe, production grows strongly, up +38%, driven by the contribution of new assets, notably in France, offsetting the scope effects related to disposals completed in 2025.
In Africa and internationally, production is multiplied by 3.0, driven by new capacity commissioned, notably in South Africa (148 MW) and Uzbekistan (126 MW).
Helexia production grows by +19%, in both Europe and Brazil.

Helexia	32.5	30.1	+8%	+6%	20.0	17.8	+13%	+10%

First-half 2026 turnover from Energy Sales reaches 190.2 million euros, up +22% at constant exchange rates (+25% at current exchange rates). This change mainly reflects favourable price effects, the contribution from new capacity commissioned and the recognition in the first half of the year of compensation related to production curtailment in Brazil. Excluding the positive impact of curtailment compensation in Brazil, the increase would have been 21.2 million euros, i.e. +14%. These factors offset lower Brazilian production, curtailment which remains significant at 218 GWh in the first half of 2026, albeit down compared with 268 GWh recorded in the first half of 2025, as well as a less favourable wind resource. Curtailment represents 13% of Brazilian production and 8% of the Group’s total production in the first half of 2026.

Energy Sales turnover is generated 49% in Latin America, 24% in Europe, 17% by Helexia production and 10% in the rest of the world.

Second-quarter 2026 turnover from Energy Sales reaches 118.2 million euros, up +40% at constant exchange rates (+46% at current exchange rates), showing a significant sequential acceleration after growth of +3% in Q1 2026. This performance is driven by turnover growth across all regions, Helexia’s contribution and the recognition of compensation related to curtailment in Brazil. Excluding this compensation, turnover growth would have been 20.4 million euros, i.e. +25%.

In Brazil, curtailment decreases in absolute terms over the quarter, but remains a significant proportion of production, given that production levels are also lower.

Renvolt

In million euros	H1 2026	H1 2025	Var. at current exchange rates	Var. at constant exchange rates	Q2 2026	Q2 2025	Var. at current exchange rates	Var. at constant exchange rates
Turnover	123.9	85.3	+45%	+45%	69.6	55.1	+26%	+26%

First-half 2026 turnover from Renvolt amounts to 123.9 million euros, up +45% at constant and current exchange rates. It is driven by continued momentum in both construction and maintenance for third-party clients, notably in Europe and Africa.

Second-quarter 2026 turnover from Renvolt amounts to 69.6 million euros, up +26% at constant and current exchange rates, driven by the contribution of around 750 MW of projects under construction for third-party clients, notably in France, Ireland, Spain and Senegal.

Voltalia Hub

Turnover	17.2	14.1	+21%	+20%	10.2	7.4	+37%	+35%

First-half 2026 turnover from Voltalia Hub amounts to 17.2 million euros, up +20% at constant exchange rates (+21% at current exchange rates). This increase notably reflects growth in specialised activities, including maintenance for third-party clients in Brazil and certain services activities.

Second-quarter 2026 turnover from Voltalia Hub amounts to 10.2 million euros, up +35% at constant exchange rates (+37% at current exchange rates), driven by growth in specialised services activities.

NEW ANNOUNCEMENTS

In Brazil, Voltalia recognises compensation related to curtailment in the first half of 2026⁷
Voltalia has completed the process to join the mechanism provided for by Brazilian Law No. 15,269/2025, entitling it to financial compensation for wind and solar production losses resulting from production limitations imposed by the National Interconnected System between September 2023 and November 2025⁸.
Following several months of regulatory and technical clarifications obtained from the Ministry of Mines and Energy and with professional associations, the uncertainties related to the implementation of the mechanism have been lifted.

In this context, Voltalia recognised in June 2026 a net compensation amount of 175 million Brazilian reals (approximately 29 million euros, based on an EUR/BRL exchange rate of 6.01), corresponding to the compensation related to losses incurred over the period. This amount includes 17 million euros of additional turnover and 12 million euros of compensated expenses, generating a total positive impact of approximately 29 million euros on first-half 2026 EBITDA.

Shareholding highlights⁹

The European Bank for Reconstruction and Development (EBRD) has fully exited Voltalia’s share capital, following the gradual reduction of its stake initiated after the 2019 capital increase. Voltalia maintains a strong relationship with the EBRD, notably through the latter’s participation in multiple project financings in Albania, Tunisia and Uzbekistan.

In addition, on 6 May 2026, VMO INVEST declared that it had crossed the threshold of 5% of Voltalia’s share capital upwards. At that date, it held 6,575,000 shares, representing 5.007% of the share capital and 2.943% of the voting rights.

In French Guiana, the Cacao biomass power plant is back in production¹⁰
The Cacao biomass power plant, located in French Guiana, restarted production in May 2026 after the shutdown that occurred in 2025 following the incident at the adjacent sawmill. This restart contributes to the gradual normalisation of asset availability in French Guiana.

In French Guiana, finalisation of the financing of the Saint Anne hybrid power plant¹¹
The financing, for a total amount of 165 million euros and co-arranged by Caisse d’Epargne CEPAC, will fund the construction and operation of a 43 MW photovoltaic solar power plant, a 135 MWh battery storage facility and a 7 MW biofuel generator in French Guiana.

This financing comprises 123.8 million euros of long-term credit and 34.6 million euros of short-term credit facilities. It is structured as a Green Loan and is aligned with the Green Loan Principles¹². As such, the funds are exclusively allocated to the financing of the project and are subject to dedicated environmental monitoring and reporting.

This project forms part of Voltalia’s development of hybrid solutions in non-interconnected areas, combining solar production, storage and dispatchable generation in order to contribute to the security of supply of the territory.
