Message from the CEO

GRI 2-22

The year 2023 was marked by important achievements and changes for Equatorial Energia S.A. ("Company"), amdist complex climate change and severe weather conditions. Some states where Equatorial Energia Group ("Company") operates were hit by storms, floods, cyclones, and landslides that impacted the lives of thousands of people, in addition to heat waves that directly impacted operations, requiring joint efforts from the entire electricity sector.

In Rio Grande do Sul, in particular, the scenario was challenging because the state faced numerous extratropical cyclones during the year, with above-average rainfall and damage that extended beyond the municipalities under concession of Companhia Estadual de Distribuição de Energia Elétrica

("CEEE Equatorial Energia"), requiring the teams to be adequately prepared with contingency strategies, and tproviding emergency assistance support, which is extremely important in caring for disaster victims. Despite the complex scenario, the concessionaire remained moving forward with the investment plan which enabled the expansion of networks and substations, essential for improving service quality and

reliability in the short and long term, as well as making progress in reducing technical losses.

In 2023, the Group has continued to directs its efforts to infrastructure and innovation, and increase its focus on its institutional strengthening, allocating 8.2 billion in consolidated investments (54% more than in the previous year), in addition to outlining strategic moves to consolidate its position as Brazil's first multi-utilities company, with integrated operations in the electric power industry and other services.

During the year, the Company maintained its focus on infrastructure development and innovation, working hard on its institutional strengthening

The second year of Echoenergia's operations under Equatorial Energia S.A. management and the Equatorial Goiás S.A's first operating cycle reinforce our commitment to seizing growth opportunities under the principles of sustainability, operating in promising markets and creating value for shareholders, always seeking better capital allocation.

emphasize the first full year of Companhia de Saneamento do Amapá SPE S.A. ("CSA") operations, the Group's first sanitation concession, which has been carrying out significant changes to the sanitation and water supply scenario in the state of Amapá. As regards transmission, we completed the sale of Intesa, which has a market value close to BRL 714 million and has contributed to

the Company's deleveraging strategy, by adapting its capital structure to possible investment opportunities.

When it comes to innovation, the highlight was the launch of EQTLab hub, a project that is part of Equatorial Group's Research and Development Program, in partnership with Aneel, dedicated to the design, development and execution of innovation and digital transformation projects. The venue was acquired by Equatorial through the Maranhão State Government's "Adote um Casarão" program and was completely

renovated. Through this initiative, our intention is to incubate technological solutions in the electricity sector and promote partnerships with public and private institutions to bring the sector closer to academia, companies and researchers.

On the ESG agenda, we were included in iDIVERSA B3, which is B3's first Latin American index to bring together companies recognized for the gender and ethnic diversity of their staff. More than 60% of Equatorial's employees are black and brown, both leaders and non-leaders.

Our social performance remained grounded in the Sustainable Development Goals (SDGs), of the United Nations Global Compact, especially those that Equatorial has identified as priorities. The Company continued to develop projects linked to the E+ Platform, focused on education, culture and sports,

in addition to laying the foundations for its new social investment guidelines. It is worth highlighting the "Escola de Eletricistas" program, which trained four classes exclusively for women, with 180 of them completing the course which covers different technical and behavioral skills.

2023

As regards the Company's environmental strategy, scheduled maintenance on our high-voltage power stations enabled us to end the year with a 43.6% reduction in the intensity of SF6 (sulfur hexafluoride) emissions, an insulating gas with high greenhouse potential.

In Governance, we also approved relevant corporate policies, such as Relationships with Stakeholders and Related Parties Policy. We also reviewed the Policies on Occupational Health and Safety, Cyber and Information Security, Disclosure of Material Acts or Facts, Securities Trading

and the Code of Conduct.

We are aware of the challenges presented in 2023 and are equally aware of how far we have come in terms of the safety and reliability of our operations, consolidating our position in sectors that are extremely important for society. We will start the new year with the same commitment, delivering consistent results to our stakeholders, always looking for opportunities alligned with our long-term strategy.
