MESSAGE FROM

THE MANAGEMENT

In the third quarter of 2022, we took an historic step forward in the direction of our decarbonization commitment: the signature of the agreement to sell the Pampa Sul Thermoelectric Plant, the final coal-fired asset in our portfolio. In this way, we are advancing our strategy of becoming a fully renewable energy generator, consolidating our position as the largest clean energy company in the Brazilian electricity sector.

The sale is aligned to the ENGIE Group's purpose of spearheading the energy transition to a carbon neutral economy. The movement towards the decarbonization of ENGIE Brasil Energia's generation matrix was intensified more than six years ago when we decided to exit coal-firedoperations and concentrate our efforts, together with more than R$ 20 billion in investments, on wind and solar-powered energy in addition to transmission infrastructure and gas transportation (through the stake in TAG).

ENGIE Brasil Energia and its indirect controlling company ENGIE S.A. have endorsed the initiative of Corporate Knights (leading sustainable economy media and research company) and Global 100 Council (council of specialists in sustainability), with a view to the committing companies to climate change and supporting the Paris Agreement. The formal endorsement took place in October and the Declaratory Action was launched on November 8th at COP27.

The Company's growth in energy from renewable sources continues even stronger and more accelerated, particularly following September's announcement of the signature of the Vestas contract to supply up to 188 model V150 wind turbines, each with a 4.5 MW capacity to the Serra do Assuruá Wind Complex, its overall installed capacity to be 846 MW when complete. This represents the conclusion of a further critical stage in the project,

allowing work to commence on the implementation of the complex, sited in Gentio do Ouro (BA), at an estimated investment of approximately R$ 6 billion.

With the addition of Serra do Assuruá to the 434 MW capacity of Santo Agostinho

Wind Complex, under construction in the state of Rio Grande do Norte, a further

1.3 GW of renewable energy will be harnessed, replacing the loss of installed capacity in the past 12 months due to the Company's complete decarbonization of its generator park, with wind and solar generation.

As already highlighted, another strategic driver of Company growth has been in the direction of the transmission infrastructure area. In this respect, it is important to emphasize as a subsequent fact to the end of the quarter, the signature on October 3rd of the Gavião Real Transmissora de Energia (new denomination of Bloc 7) concession, for which the Company bid successfully at Aneel's transmission auction in June. This project envisages the installation of one kilometer of transmission line in the state of Pará together with a substation, complementary to the Novo Estado Project, currently under construction.

The financial performance in 3Q22 was also positive due to organic growth -

addition of the installed capacity of the Campo Largo II Wind Complex and Paracatu and Floresta photovoltaic complexes

• and the consequent increase in the volume of energy available for sale, in addition to the higher average selling price and the impact of inflationary deceleration on loans, financing, debentures and concessions payable. With this, ENGIE Brasil Energia reported a net adjusted profit at R$ 710 million, 17.2% higher than the same quarter in 2021.

Net operating revenue reached R$ 2.7 billion, (-18.9% vs 3Q21), the result of a decrease in revenue from transmission lines construction due to progress made in work on the projects, this effect attenuated by the combination of increased volume and average price for power selling agreements. Adjusted Ebitda recorded a reduction of 15.7% in relation to 3Q21, registering R$ 1.4 billion in 3Q22, a consequence of the aforementioned effects, in addition to the recognition, in 3Q21, of the complement to the amount already recognized in previous periods referring to the hydrological risk renegotiation (R$ 372 million). Excluding the mentioned effect Ebitda would have grown by 8%. The Adjusted Ebitda Margin increased by 2.0 p.p. reaching 52.1% in 3Q22.

With the reclassification of the assets and liabilities of Pampa Sul Thermoelectric Plant as an Asset held for sale, the Company's net debt in 3Q22 stood at R$ 15.0 billion, a reduction of 8.3% in relation to 2Q22. Our cash position, of the order of R$ 3.8 billion and the net debt/Ebitda ratio of 2.0x, maintained the Company's comfortable situation, in line with the financial position necessary for desired growth.

ENGIE Brasil Energia - Earnings Release 3Q22	4

Just as important as growing pari passu with respect for and committed to the environment, is evolving in the care of our people. With occupational health and safety of the employees as a license to operate, in July we ran our Safety Meeting, with 40 technicians and engineers, all of them in the operating areas of the plants, transmission lines or at projects in the process of implementation. And Mental Health was the driver of our awareness actions with employees during the entire month of September.

Continuing our objective of acting on the basis of a plurality of ideas, at the forefront of the electricity sector, we received on October 3rd the 13 engineers selected for the first Trainees Program with affirmative vacancies set aside specifically for women. These professionals, who will work at our plants, underwent an intense process of selection and are due to reinforce our Operations & Maintenance and Implementation teams in nine states around the country.

In the same month, we concluded an important process of active listening and dialog with stakeholders. Conducted in different regions of Brazil, the initiative has already involved approximately 250 people among employees, community leaders, educators, local suppliers and third sector representatives together with government entities. These dialogs are essential for steering initiatives of engagement as well as building the materiality matrix, a base for deciding the themes to be raised in our Sustainability Report for 2022.

In the 3Q22, for the 20th consecutive year, the Bureau Veritas Certification recommended recertification of our Integrated Management System (SIG), the scope of which covers the Company's headquarters, energy generation services at the hydropower plants and remote hydro operations in accordance with NBR ISO 9001 - Quality Management; NBR ISO 14001 - Environmental Management and ISO 45001 - Occupational Health and Safety Management standards.

As from November, ENGIE Brasil Energia's Administrative Office is to be known as People, Processes and Sustainability Office. The change in name has the purpose of adequately reflect the functions and responsibilities of the area, which is in charge of People & Culture; Environment; Social Responsibility; Communication; Technology of Information & Digital; Documentation, Premises and Supplies.

We come to the end of this message on a note of optimism. We cannot fail to conclude without making mention of an important step forward for the sector: the opening of the Free Energy Market. Published by the Ministry of Mines and Energy (MME) on September 27, Ordinance 50/2022 permits all high voltage consumers to migrate to the Free Energy Market as from January 2024. The decision guarantees freedom of choice to these consumers to negotiate prices and conditions for contracting energy directly with the suppliers - whether generators, traders or intermediate agents operating in the sector. This is a step which will intensify market dynamics to the benefit of healthy competition and with the potential to make the country more competitive. It is indeed an initiative which needs to be commemorated and one which will accelerate our strategy of digitalization with a client focus still further!

Good reading!
