Message from the CEO The year of 2019 was marked by another important step for Equatorial Energy Group’s growth, especially in the transmission and distribution segments. With regard to transmission, the company obtained environmental licenses for all of its 8 work site lots. In addition, in June 2019 the Rurópolis Substation’s Synchronous Compensator was commissioned, a part of SPE 08 and with a RAP (Annual Permitted Revenue) equal to roughly R$ 18 million. This portion of the lot’s start of operations represented an advance of roughly 37 months on the regulatory deadline. As for electricity distribution, 2019 was a milestone of the start of operations by our Alagoas concession and consolidation of our Piauí operations. The turnaround by these new distributors has already been converted into positive outcomes, with the development of actions involving improved operating quality in electricity supply as well as commercial assistance. We should also stress contractual discussions with third parties (anchor agreements), a focus on fighting losses and readapting our cost structure, among other actions. The year of 2019 involved important investments, in particular those directed at transmission, totaling R$ 2.9 billion. Moreover, please note that we already have available 100% of the funding for new contractual lots, adding safety to the group’s liquidity aspect. Within the distribution segment, the total invested reached R$ 1.8 billion, considering the use of own resources and the investment for the Light for All Program. Those investments aim at the expansion and maintenance of the networks, improvement in the quality of supply, universal access to the grid and the interconnection of isolated systems in Pará. This high level investment allowed Equatorial Maranhão and Equatorial Pará to maintain their quality figures (DEC and FEC) substantially better than their regulatory targets, reaching 13.7 hours and 6.6 times in Maranhão, and 21.8 hours and 12.6 hours times in Pará. It is relevant that in Aneel’s quality ranking Equatorial Pará has been placed in 2nd place among major distributors, of which fact we are very proud. We are certain that our new distributors are also on the path to achieving operating excellence. From the financial angle, we continue to reflect stable profit figures as well as safety from a liquidity viewpoint, having ended the year with a consolidated cash position of R$ 5.829 billion. We are proud to announce that our distribution companies - Equatorial Maranhão and Equatorial Pará - were ranked amongst the best 100 companies to work for in Brazil in the Great Place to Work ranking, demonstrating the appreciation and dedication that we have for our people. We wish to thank all our employees, shareholders, suppliers and partners for their support and confidence over these years. Augusto Miranda da Paz Junior Chief Executive Officer 04.

Billings rose to 6,435 GWh, representing a 3.4 p.p. increase over 2018. The energy losses recorded by the Company in 2018 were 1,411 GWh, or 18.0% of required energy, resulting in losses rising by 0.8 p.p. on 2018. Total losses on required energy (Last 12 months) Los s 12 months Regulatory target loss 12 months loss 12 Non-technicalmonths losses on low-voltage market (Last 12 months) Regulatory target Fiscal measurement was essential to achieve one of the highlights of 2019, reaching the milestone of 10.8 thousand monitored transformers. Out of this amount, 6.2 thousand are located on the island of São Luís, where we saw a decrease of 0.6 percentage points on 2018 and 2019. This result was important to keep the Company's loss ratio in check and nearly within the regulatory target. We highlight below the results of the actions taken in the plan for combating losses in 2019: • Implementation of the Mobile technology in the Inspection procedure; • Regularization of 2.9 thousand clients in an area of improvised installations and connections where it was necessary to carry out medium and low-voltage network extensions; • Inspection of 4.5 thousand clients with supply of medium and high voltage power; • Installation of 236 telemetering systems in clients with medium voltage supply which will enable monitoring in real time of the consumption and demands of the units, in addition to the
