For the purpose of tax exemption, exemption from withholding tax, or reduction of the withholding tax rate on income tax (IRS/IRC), shareholders should verify their tax situation and provide evidence of all the facts on which these exceptions depend, to the financial intermediary where their shares are registered.

The dividends paid to individual shareholders, resident for tax purposes in Portuguese territory and subject to IRS taxation (Portuguese Personal Income Tax) are subject to a final tax rate of 28%, without prejudice to the option of aggregating the distributed dividends (50% of the amount) with the remaining taxable income, provided that they are obtained outside the scope of business and professional activities.

The dividends paid to corporate shareholders, resident for tax purposes in Portuguese territory and subject to taxation under IRC (Portuguese Corporate Income Tax) are subject to a withholding tax rate of 25%, deductible to the amount of IRC payable, unless the dividends are paid or made available to accounts in the name of one or more accountholders, acting on behalf of unidentified third parties, except when the beneficial owner is identified, in which case the general rules shall apply.

The dividends paid to non-resident shareholders who do not have a permanent establishment in Portuguese territory or, having a permanent establishment, the dividends are not attributable to it, are subject to a final withholding tax (personal income tax at 28% and corporate income tax at 25%).

Sonaecom further informs that its shares will trade ex-dividend as from and including the second business day (May 20, 2025) prior to the payment date.
