Turnover growth of +20% in Q4 2023 Record volume of new capacity commissioning and confirmation of normalised EBITDA target¹ for 2023

Fourth quarter with strong growth of +20%

• Energy sales: +16% driven by an increase in production compared to 2022 (+11% to 1.3 TWh)
• Services: up +24% (after eliminations) mainly driven by construction contracts for third-party clients in Ireland, in parallel with a particularly dynamic internal activity (eliminated in consolidation) at +50% due to the peak in own-account construction sites

Exceeding 2023 capacity targets

• Record level of commissioning during the second half: 662 megawatts, including 316 megawatts in Q4 alone
• Capacity in operation up +51% to 2.37 gigawatts, exceeding the target of 2.3 gigawatts announced in October 2023
• Total capacity at the end of 2023 at 2.85 gigawatts, well above the target initially set in 2019 at 2.6 gigawatts
• A major contribution to the energy transition with production equivalent to the electricity consumption of 5.5 million people

Confirmation of the 2023 normalised EBITDA target of around €275 million

• A doubling compared to 2022 and a fourfold increase compared to June 2019
• Major achievements in the second half of the year, including projects sales in France and Brazil

Voltalia (Euronext Paris, ISIN code: FR0011995588), an international player in renewable energies, publishes its fourth quarter 2023 turnover.

"The year 2023 will mark the history of our company through the remarkable performances we have achieved thanks to the unwavering mobilization of the teams, whom I sincerely thank for their commitment. We reached a significant milestone by commissioning 795 MW, far exceeding the targets we set for ourselves in 2019. Our teams are already fully mobilized to achieve the group's ambitions by 2027. Beyond the financial successes, I would like to highlight the significant progress in the Group's non-financial performance, with ratings constantly improving, thus demonstrating our position as a major contributor to a sustainable energy future", comments Sébastien Clerc, CEO of Voltalia.

For 2023, the production reached 4.3 TWh, compared to 3.7 TWh in 2022, up +18%. The production of 4.3 TWh corresponds to the electricity consumption of an equivalent of 5.5 million people (+12% compared to 2022).

² The above amounts are the sum of the consolidated data, rounded to the first decimal place

³ The installed capacity includes the Mosselbanken solar power plant in the Netherlands, 55% owned by Voltalia but not consolidated (not included in either turnover or production)

January 31st , 2024

The increase in production reflects the increase in operating capacity, which has increased by +51% since 2022, from 1.6 GW to 2.4 GW. At the end of 2023, total capacity (in operation and under construction) in Latin America represents 57% of the Group's total capacity, Europe 35% and Africa 8%. Solar capacity accounts for 66% of the total, wind capacity for 30% and hydro, biomass and storage capacity for 3%.

Q4 2023 turnover from Energy sales reached €82.9 million, up +16% at current and constant exchange rates, compared to the fourth quarter of 2022.

Analysis by country:

• In Brazil, production is up +3%. The contribution of new plants such as SSM3-6 and Canudos have had a positive effect. On the other hand, as announced⁴ , the grid operator has capped the production of some power plants following the blackout on August 15th. This reduced Q4 production by around 180 GWh, in line with the Group's forecast. The curtailment effect has decreased over the months. Since the beginning of 2024, it has been negligible;
• In France, production is up 92%, benefiting from better wind and solar conditions and the production of power plants commissioned in 2022 and 2023 (Helexia, Sable blanc, Sud Vannier);
• In the other countries, production was up sharply overall, at +30%, with the full-year effect of the South Farm power plant (50 MW) in the United Kingdom and the commissioning of the Garrido complex (51 MW) in Portugal and Helexia's solar rooftops in Spain and Hungary (9 MW). The Karavasta power plant in Albania (140 MW), commissioned at the end of December, generates negligible turnover. Production remains broadly stable in Egypt and Jordan.

SERVICES

2023 turnover from Services for third-party clients (after eliminations) reached €195.9 million, down -12% (at constant and current exchange rates), while internal services (eliminated in consolidation) increased by x3.1 compared to 2022.

• The Development, Construction and Equipment Procurement segment for third-party clients was down 16% to €172.8 million, not including proceeds from projects sales⁵ . The internal activity of this segment was up x3.4 compared to 2022;
• The Operations & Maintenance segment for third-party clients grows by 26% to €23.1 million, in parallel with internal activity which increased by +8%.

Q4 2023 turnover from Services for third-party clients reached €87.1 million, +24% (at current and constant exchange rates). Internal Services activity grows by +50% to reach €101.9 million.

The analysis by segment shows a strong growth in the Development, Construction and Equipment Procurement segment:

• The Development, Construction and Equipment Procurement for third-party clients segment posts an €80.6 million turnover, up +24%, reflecting the ramp-up of major construction contracts for third-party clients, particularly in Ireland. Internal turnover in this segment increases by +52% to €96.9 million, reflecting active construction sites;

⁵ From 2022, the Group publishes its turnover. Income from the disposal of tangible or intangible assets is recorded under "Other current income and expenses".

January 31st , 2024

• The Operations & Maintenance segment records a turnover of €6.5 million for third-party clients, up +20%. The capacity operated on behalf of internal and external clients amounts to 6.9 GW, up +58% compared to 2022, including 4.6 GW for external clients, up +63%.

2023 eliminations and Q4 2023 eliminations amount to -€400.0 million (multiplied by x3.1 at current and constant exchange rates) and -€101.9 million (+50% at current and constant exchange rates), respectively, reflecting the strong increase in internal services.

RECENT DEVELOPMENTS

• First megawatt-hours for the Karavasta solar power plant in southern Albania ⁶

With a total capacity of 140 MW, all of the plant's capacity is secured by long-term electricity sales contracts with public and private players.

• Commissioning of Logelbach solar power plant in France⁷

With a capacity of 12.1 megawatts, the Logelbach solar farm covers 12 hectares and has 21,384 solar panels. Annual production is equivalent to the electricity consumption of around 6,000 people.

• Commissioning of the Montclar solar farm in France⁸

The 3.7-MW Montclar power station, installed over an area of 4.2 hectares, comprises around 8,400 solar panels. Construction was a challenge, as the site is located in a mountainous landscape with steep slopes at an altitude of 1,350 meters.

• New progress in future clusters combining solar, wind and storage in Uzbekistan⁹

Voltalia has signed two agreements consolidating the development of its projects in the country: a protocol covering the next stages in the development of the Shurkul hybrid project (400 to 500 MW); and a protocol for the extension of the Sarimay project, providing for the hybridisation of the solar project with the addition of a further 100 MW of wind power, combined with battery storage solutions.

• United Kingdom for the supply of sustainable green electricity¹⁰

Co-op and Voltalia have jointly signed a 15-year power sales agreement for the entire output of the 34 MW Eastgate solar farm in North Yorkshire. Under the agreement, Co-op will source electricity for its premises, including food shops, distribution centres and funeral homes across the UK.

• Voltalia wins three wind farm projects in France with a total capacity of 73 megawatts¹¹

The first winning project will be located in Côte d'Or (Bourgogne-Franche-Comté region), with ten wind turbines and a total output of 33.6 MW. The second will be located in Deux-Sèvres (Nouvelle-Aquitaine region), with seven wind turbines and a total output of 26.1 MW.
