(1) Refer to power generation concession agreements that are not in the scope of IFRIC 12, whose infrastructure assets are recorded as property, plant and equipment since the grantor does not control to whom the services should be provided and their price, and their energy is mainly sold in the Free Contracting Environment (‘ACL’). (2) Refers to energy generation concession contracts whose concession bonus revenue is classified as financial assets of the concession. (3) Refer to concessions, by means of authorization, of wind power generation in the independent production modality, commercialized in the scope of Proinfa. The assets linked to the exploration right are registered in fixed assets. The exploration authorization rights, which are considered in the parent company's financial statements as investments, are classified in the consolidated balance sheet as intangible assets. (4) These refer to power transmission concession agreements which, in accordance with IFRS 15, are classified as contract assets as they are subject to the satisfaction of performance obligations in the provision of the electric energy transmission service. (5) On March 17, 2023, ANEEL Order 738 was published, registering the change of name of the Emborcação HPP to Theodomiro Carneiro Santiago HPP. (6) On August 10, 2023, the Company held a public auction for the sale in a single lot of 15 SHPPs/CGHs, 12 of which are Cemig GT assets and 3 of which are owned by the wholly owned subsidiary Horizontes.

On February 6, 2024, ANEEL authorized the transfer of the concessions of the Rio de Pedras and São Bernardo SHPs from Cemig GT to Mang Participações, through REA 15,094. On 29 February 2024, the divestment was completed, after all conditions precedent of the VCA had been fulfilled. Further details can be found in note 32: Assets classified as held for sale. (7) In July 2023, the Company reaffirmed its interest in extending the concessions for the Theodomiro Carneiro Santiago and Nova Ponte HPPs under the Physical Guarantee Quota regime, and in November 2023, it filed its expression of interest in extending these concessions by transferring control of the plants.

(9) On January 24, 2023, ANEEL decided to approve the transfer of the concessions for the Três Marias and Salto Grande hydroelectric plants to Cemig GT.
