Dividends received by non-resident shareholders will be exempt from income tax in terms of section 10(1)(k)(i) of the Income Tax Act. The dividend withholding tax rate is 20%, accordingly, any dividend will be subject to dividend withholding tax levied at a rate of 20%, unless the rate is reduced in terms of any applicable agreement for the avoidance of double taxation (DTA) between South Africa and the country of residence of the shareholder.

Should dividend withholding tax be withheld at a rate of 20%, the net dividend amount due to non-resident shareholders is 600.00000 SA cents per share. A reduced dividend withholding rate in terms of the applicable DTA may only be relied on if the non-resident shareholder has provided the following forms to their CSDP or broker, as the case may be in respect of uncertificated shares or the company, in respect of certificated shares:

(a)a declaration that the dividend is subject to a reduced rate as a result of the application of a DTA; and

(b)a written undertaking to inform the CSDP or broker, as the case may be, should the circumstances affecting the reduced rate change or the beneficial owner cease to be the beneficial owner,

both in the form prescribed by the Commissioner for the South African Revenue Service. Non-resident shareholders are advised to contact their CSDP or broker, as the case may be, to arrange for the abovementioned documents to be submitted prior to the payment of the distribution if such documents have not already been submitted.

In compliance with the requirements of Strate Proprietary Limited (Strate) and the JSE Listings Requirements, the salient dates for payment of the dividend are as follows:

No dematerialisation or rematerialisation of share certificates may occur between Wednesday, 7 October 2026 and Friday, 9 October 2026 both dates inclusive, nor may any transfers between registers take place during this period.

On payment date, dividends due to holders of certificated securities on the SA share register will either be electronically transferred to such shareholders' bank accounts or, in the absence of suitable mandates, dividends will be held in escrow by Harmony until suitable mandates are received to electronically transfer dividends to such shareholders.

Dividends in respect of dematerialised shareholdings will be credited to such shareholders' accounts with the relevant CSDP or broker.

Assuming an exchange rate of R16.00/US$1* the dividend payable on an ADR is equivalent to 46.86651 US cents for ADR holders before dividend tax. However, the actual rate of payment will depend on the exchange rate on the date for currency conversion.
