ISFUT Information. Paz Corp S.A. 2026

Dear participants,

Depósito Central de Valores (DCV) hereby informs you that Paz Corp S.A. (hereinafter referred to interchangeably as “Paz” or the “Company”), pursuant to the matters approved at the Ordinary Shareholders’ Meeting held on April 28, 2026, at 9:00 a.m. (the “Meeting”), is making the following information available to its shareholders regarding the substitute tax regime for final taxes, with respect to the retained earnings in the Company’s taxable earnings fund (“ISFUT”). This optional regime was in effect until the last business day of April 2022, with respect to the balance of accumulated earnings pending taxation as of December 31, 2021, and recorded in the Company’s FUT register as of December 31, 2016.

To that end, Paz is informing its shareholders of the following regarding the ISFUT regime and the procedure for qualifying for it:

1. Pursuant to Transitional Article 25 of Law No. 21,210, the Company was able to include its taxable profits accumulated through December 31, 2016, and pending taxation, in the final taxes payable upon payment of the ISFUT.
2. Once the ISFUT has been paid, the profits subject to this regime are deemed to have fully complied with their taxation through the aforementioned final taxes and may be withdrawn or distributed at the time deemed appropriate, without being subject to the allocation rules established by the Income Tax Law (“LIR”).
3. In this regard, as agreed at the Ordinary Shareholders’ Meeting held on April 20, 2022 (“2022 Meeting”), the Company applied a portion of the accumulated taxable profits it had recorded to the payment of ISFUT, for a total amount of M$35,877,657. For the purposes of the ISFUT return and payment, Paz has determined an effective first-category tax credit rate (or “TEF”) of 0.2693, which was applied to the taxable profits subject to this regime. As a result of the foregoing, the ISFUT payment amounted to a total of M$4,000,000. Furthermore, at the 2022 Shareholders’ Meeting, the shareholders agreed that the amounts paid by the Company as ISFUT, which will be charged against future dividend distributions, will be subject to an additional charge associated with the alternative use of funds, corresponding to interest equivalent to the return obtained by the Company on peso-denominated time deposits held during the period from May 1, 2022, to the last day of the month preceding the date set for payment of the respective dividend (the “Charge”).
4. With respect to the amount allocated to the ISFUT referred to in point 3 above, the Company has withheld M$2,348,934, corresponding to those shareholders who allocated their dividend distributions approved at the 2022 Meeting and at the Annual Shareholders’ Meetings for the years 2023, 2024, and 2025 to the ISFUT, therefore, as of this date, the balance of M$1,651,066 remains pending allocation.
5. With respect to the payment of dividends to be submitted for the shareholders’ consideration and decision, and prior to the date set for the payment of such dividends, a form defining the procedure to be followed to opt for the ISFUT regime will be made available to those shareholders who wish to avail themselves of that regime.
6. In the event that a shareholder instructs the Company to pay the dividend to which they are entitled, charged against profits subject to the ISFUT regime, the amount to be withheld from the dividend payable to such shareholders for ISFUT purposes shall be $2.5657 pesos per share, so that the corresponding balance may subsequently be distributed to them. The aforementioned withholding amount consists, on the one hand, of the ISFUT paid by the Company, amounting to $1.9718 pesos per share, and, on the other hand, of the Charge, as approved at the 2022 Shareholders’ Meeting, amounting to $0.5939 pesos per share.
7. Profits subject to the ISFUT regime that are not fully distributed to shareholders as part of the dividend distribution approved by the Meeting shall remain recorded in the Company’s exempt income register (“REX”) and may be distributed in subsequent fiscal years, when deemed appropriate, without being subject to the allocation rules established by the Income Tax Law (LIR). The ISFUT declared and paid by the Company, to the extent not allocated to the distribution approved by the Board, constitutes and shall constitute an account receivable in its favor, which shall be allocated to dividend distributions agreed upon subsequently, and in the corresponding proportion, with respect to those shareholders of the Company who decide to opt to receive dividends charged against the balance of profits subject to ISFUT and recorded in the REX register. Said account receivable shall be subject to the corresponding charge in accordance with the calculation formula approved at the 2022 Shareholders’ Meeting. In any case, the payment date for the dividend approved at the Meeting will be May 28, 2026, regardless of whether the shareholder exercises the option indicated in paragraph 6 above.
8. Finally, shareholders wishing to exercise this right must submit the “INSTRUCTIONS FOR ISFUT PAYMENT FORM” made available to shareholders at the following website https://www.paz.cl/informacion-general/junta-accionistas, and send a signed copy of said instructions to the indicated email and/or physical addresses no later than May 22, 2025, at 2:00 p.m.
