CORRECTION ANNOUNCEMENT: DIVIDEND TAX APPLICABLE TO SOUTH AFRICAN SHAREHOLDERS

Reference is made to the interim results for the six months ended 31 March 2024 and interim dividend declaration released on SENS on 23 May 2024.

Please take note of a correction to the dividend tax paragraph, as it relates to South African tax residents:

South African tax residents

South African shareholders are advised that the dividend constitutes a foreign dividend. For individual South African tax resident shareholders, dividend withholding tax of 20% will be applied to the gross dividend of 27.28065 South African cents per share. Therefore, the net dividend of 21.82452 South African cents per share will be paid after 5.45613 South African cents in terms of dividend withholding tax has been applied.

Shareholders who are South African tax resident companies are exempt from dividend tax and will receive the dividend of 27.28065 South African cents per share.

This does not constitute legal or tax advice and is based on taxation law and practice in South Africa. Shareholders should consult their brokers, financial and/or tax advisors with regard to how they will be impacted by the payment of the dividend.
