(1) In 2022, a provision was recorded as a result of Law 14385/22, which determined the fully destination, for the benefit of consumers, of the amounts subject to repeal of debt by the distributors, related to the exclusion of ICMS from the PIS/Pasep and Cofins calculation basis. The amount refers to the period from the 11th year onwards, counted retroactively from the date of the final and unappealable decision in the lawsuit, net of the portion included in the 2022 and 2023 Annual Tariff Adjustments.

There was no impact on the Company's results, the effect of the change being related only to disclosure. For comparability purposes, the change was reflected in the 2022 financial year based on the same criteria. For further details, see note 3.8.

In 2022, the balance of this update was taxed, but with the STF's favorable decision, the balance was excluded in the 2023 calculation. Accounting policy The income tax and social contribution tax expenses represents the total amount of current and deferred taxes, which are presented separately in the financial statements. The Company is subject to the regular tax regime ‘Lucro Real’. However, its subsidiaries that can benefit from the favorable tax regime, according to tax law, analyze the payable tax projection for the next year, in order to determine the tax regime that reduces its taxes payment. Deferred and current tax items are recognized in correlation to the underlying transaction either in OCI or directly in equity. Periodically, in accordance with IFRIC 23, the Company and its subsidiaries evaluate positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate. Current Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at the reporting date. Advances, or tax credits, are presented as current or non-current assets, in accordance with the expected date of their realization at the balance sheet date, when the tax amounts are duly calculated and offset against advances made. Deferred Deferred tax is recognized for temporary differences between the carrying amount of an asset or liability in the statement of financial position and its tax base at the reporting date. Government grants Government grants are recognized when there is reasonable assurance that the grant will be received, and all attached conditions will be complied with, in line with IAS 20. The subsidiaries Cemig D e GT have ventures in an area incentivized by SUDENE area, which result in the recognition of its right to a 75% reduction in income tax. Such tax incentives, in the form of exemption or reduction of income tax, comply with the concept of government grants and are recognized as income on a systematic basis over the periods that the related income tax expense for which it is intended to compensate, is recorded. Given the legal restriction on the distribution of net income corresponding to the tax incentive, the Company maintains the amount related to the incentive granted in the tax incentive reserve. For more details, see note no. 6. Estimations and judgments Deferred taxes Deferred tax liabilities are recognized for all the inter-temporal tax differences. Deferred tax assets are recognized for all the temporary differences deductible, to the extent that it is probable that future taxable income will be available for the temporary differences to be offset, except: • When the deferred tax asset or liability arises from recognition of goodwill or of an asset or liability in a transaction which is not a business combination and, on the date of the transaction, does not affect the accounting profit or the profit or loss for tax purposes, except when the transaction gives rise to temporary differences that are both taxable and deductible, in which the entity must recognize a deferred tax asset or liability and must recognize the resulting deferred tax expense or revenue in the income statement; • In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint arrangements, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future; and • In respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint arrangements, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable income will be available against which the temporary differences can be utilized. These taxes are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date. Deferred income tax and social contribution tax assets are reviewed at the reporting date, and are reduced to the extent that their realization is no longer probable or recognized to the extent that it becomes probable that future taxable incomes will allow them to be recovered. The Company offsets deferred tax assets and deferred tax liabilities if and only if it has a legally enforceable right to set off current tax assets and current tax liabilities and the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same taxation authority on the same taxable entity. The estimated taxable incomes forecast, on which the realization of deferred tax asset are based, are determined by the annual budget and the long-term budget, both reviewed periodically, and by the historical income. However, the taxable income may be either higher or lower than the evaluation used by the management when the amount of the deferred tax recognized was determined. Uncertainties on the treatment of taxes on profit There are certain matters regarding treatment of taxes on profit about which the Company has uncertainties. The uncertainties about the treatment of taxes on profit represent the risks that the tax authority may not accept a given tax treatment applied by the Company. The Company estimates the probability of the tax authority accepting the uncertain tax treatment based on technical assessments of its legal advisors.
