23. POST-EMPLOYMENT OBLIGATIONS

Forluz Pension plan (a Supplementary retirement pension plan)

CEMIG and its subsidiaries are sponsors of Forluz - Forluminas Social Security Foundation, a non-profit legal entity whose object is to provide its associates and participants and their dependents with a finance income to complement retirement and pension, in accordance with the pension plan that they are subscribed in.

Forluz provides the following supplementary pension benefit plans available to its participants:

Mixed Benefit Plan (‘Plan B’): This plan operates as a defined-contribution plan in the fund accumulation phase for retirement benefits for normal time of service, and as a defined-benefit plan for disability or death of participants still in active employment, and for receipt of benefits for time of contribution. The Sponsors match the basic monthly contributions of the participants. This is the only plan open for joining by new participants. The actuarial risks related to Plan B occur only as from the option for the lifetime benefit at the moment of the participant’s retirement. In this specific case the responsibility for the risk of insufficiency of reserves for coverage of the benefits (deficits) is in parity between sponsors and participants.

Funded Benefit Plan (‘Plan A’): This plan includes all currently employed and assisted participants who opted to migrate from the Company’s previously sponsored defined benefit plan and are entitled to a benefit proportional to those balances. For participants who are still working, this benefit has been deferred to the retirement date. The benefit balances of Plan A have the characteristic of lifetime payment, and the responsibility for the risk of insufficiency of reserves to cover the benefits (deficits) is exclusively that of the sponsors.

Cemig GT and Cemig D, independently of the plans made available by Forluz, also maintain contributions to the Integrated Pro-Saúde Plan (Plano Prosaúde Integrado – PSI) and the Dental Plan (Plano Odontológico – POD) for the employees, retirees and dependents, managed by Cemig Saúde.

Integrated Prosaúde Plan (PSI): This is a health plan for active and retired employees and their dependents, managed by Cemig Saúde, which provides outpatient and hospital care, including obstetric care, in an accredited network with nationwide reach. The coverage is mainly executed by the Benchmark Healthcare Program (Programa de Referência de Assistência à Saúde – PRAS). There are also reimbursements of medical expenses through the Special Guarantees Program (PTE) and the Complementary Healthcare Fund (FCAS).

Dental Program (POD): This dental plan is offered by the Company to active and retired employees and their dependents, with nationwide coverage, managed by Cemig Saúde in partnership with Odontoprev.

Actuarial obligations and recognition in the financial statements

On this Note the Company discloses its obligations and expenses incurred for purposes of the Retirement Plan, Health Plan, Dental Plan and the Life Insurance Plan in accordance with the terms of IAS 19 - Employee Benefits, and the independent actuarial opinion issued as of December 31, 2024.

Agreement to cover the deficit on Forluz Pension Plan ‘A’

Forluz and the sponsors CEMIG, CEMIG GT and CEMIG D have signed a Debt Assumption Instrument to cover the deficit of Plan A for the years of 2015, 2016 and 2017.

The monthly amortizations, calculated by the constant installments system (Price Table), will be paid up to 2031 for the 2015 and 2016 deficits, in the amount of R$323, and up to 2033 for the 2017 deficit, in the amount of R$171. Remuneratory interest applicable to the outstanding balance is 6% p.y., plus the effect of the IPCA. If the plan reaches actuarial surplus before the full period of amortization of the debt, the Company will not be required to pay the remaining installments and the contract will be extinguished.

On December 31, 2024 the total amount payable by Cemig and its subsidiaries as a result of the Plan A deficits was R$494 (R$545 on December 31, 2023 referring to the Plan A deficits of 2015, 2016 and 2017).

Forluz consignment deposits

In accordance with the specific legislation, Forluz sent Cemig a proposal to enter into new Private Debt Assumption Instruments between Forluz and the sponsors Cemig, Cemig GT and Cemig D, according to the settlement plan to cover the deficit of Forluz's Plan A in 2019, 2020 and 2021. In the case of deficit settlements, if the plan reaches actuarial balance before the full amortization period of the contract, the Company would be exempt from paying the remaining installments and the contract would be extinguished.

The Company, recognizing its legal obligation with regard to the Plan A deficit, corresponding to 50% of the minimum amount, respecting the rule of contributory parity, makes consignment payments into a judicial deposit account, which are available to Forluz to be redeemed at any time at the official bank. The deposits are constituted monthly by the amount of 50% of the installment of each of the 2019, 2020 and 2021 Deficit Equalizations, as follows:

	Deficit of pension fund 2019		Deficit of pension fund 2020		Deficit of pension fund 2021
Start of consignment		May, 2021		April, 2022		In process
Total amount requested by Forluz		R$160		R$252		R$670
Amount considering contribution parity		R$80		R$126		R$335
Number of parcels		166		158		159
Remuneratory interest		IPCA + 6%		IPCA + 5.7%		IPCA + 5.51%
Balance deposited on December 31, 2024		R$38		R$42		R$56

Forluz sent the Company new equalization plans which are being assessed by Management, referring to the 2022 and 2023 actuarial deficits of the Salted Pension Benefits Plan - Plan A. The minimum amount of the accumulated deficits for equalization is R$1,207, of which the Company has been making consignment payments for the 2019, 2020 and 2021 deficits.

Forluz, due to (i) the non-execution of the Debt Assumption Agreement to cover the minimum proposed amount in the plan for the actuarial deficit of Plan A in the years of 2019, 2020 and 2021, and (ii) the refusal of the Company's consignment payments. Forluz entered with a lawsuit, against sponsor Cemig D. The Company is applying for the courts to approve the request for compliance with the contracting of the debt to cover the total amount of the deficit of Plan A. Judgment was given in favor of Forluz in the first instance decision by the Minas Gerais Appeal Court in 2022, in relation to the process of settlement of the deficit of 2019, but appeal lies for further dispute at higher instances of the Courts system. As a result, based on the assessments of its specialists, the Company has opted to maintain the assessment of chances of loss in the action as ‘possible’.

Debt with the pension fund (Forluz)

Debt installments agreed with Forluz, referring to past actuarial deficits, were settled on June 30, 2024. The installments were amortized monthly, calculated on the basis of the constant-installment method (the ‘Price Table’) and updated by the IPCA (National Consumer Price) inflation index issued by the IBGE (Brazilian Geography and Statistics Institute) plus 6% per year. This debt was paid regardless of whether there was a surplus in the Foundation, and the effects of monetary updating and interest were posted in the Income statement.

Actuarial losses and gains, net of income tax and social contribution, do not involve cash and are therefore not reflected in the Cash Flow Statements.

Amounts recorded as current liabilities refer to contributions to be made by CEMIG and its subsidiaries in the next 12 months for the amortization of the actuarial liabilities.

The amounts reported as ‘Expense recognized in the Statement of income’ refer to the costs of post-employment obligations, that include the past service cost arising from the cancellation of the post-retirement life insurance obligation, totaling R$485 (R$591 on December 31, 2023), plus the finance expenses and monetary updating on the debt with Forluz, in the amounts of R$3 (R$20 on December 31, 2023).

The Company has not made changes in the methods used to calculate its post-employment obligations for the years ended December 31, 2024 and 2023.

Accounting policy

Expenses related to the debt agreed upon with the pension trust fund were recorded in finance income (expenses), because they represent financial interest and inflation adjustment. Other expenses related to the pension fund were recorded as operating expenses.

Estimations and judgments

In the case of retirement obligations, the liability recognized in the balance sheet with respect to defined benefit pension plans is the greater of the debt agreed with the foundation for amortization of actuarial obligations and the present value of the actuarial obligation, calculated by means of an actuarial report, less the fair value of the plan's assets.

The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using the rate of return on high-quality corporate bonds that have terms similar to the duration of the respective pension plan obligations and are denominated in the currency in which the benefits will be paid.

In defined contribution plans, the Company makes fixed contributions and has no legal or constructive obligations to make contributions if the fund does not have sufficient assets to pay all employees the related benefits. The Company has no additional payment obligation after the contribution is made. Contributions are recognized as an employee benefits expense when due.

In the case of the health and dental plans, the liabilities are calculated by calculating the present value of the future obligations to be made by the Company, considering the maintenance of the current contribution level, the forecast of a real readjustment of the amounts and the future updating of the contributions by the variation of an index compatible with the Regulations and the history of the costs of the plans.

Actuarial calculations take place at each financial year end and involve the use of assumptions about discount rates, expected rates of return on assets, future salary increases, mortality rates and future increases in retirement and pension benefits. All assumptions are reviewed at each base date.

In the current and previous years, post-employment expenses are recorded as operating expenses, with the exception of expenses related to the debt agreed with the Pension Fund, which are recorded in the financial result, as they represent interest and monetary variation.

Actuarial gains and losses arising from adjustments based on experience and changes in actuarial assumptions are recognized through other comprehensive income and will not be reclassified to profit or loss in the future.

Both the past service cost resulting from a change or reduction in the defined benefit plan and the gain or loss on the settlement of obligations are determined based on the remeasurement of the net present value of the obligation, due to the revision of actuarial assumptions, and are recognized directly in profit or loss for the year in which the change occurs.
