Noteholder are further advised that the Sustainability Certificate (as defined in the Applicable Pricing Supplements for RWL26 and RWL 28) which is accompanied by the key performance indicator auditor's limited assurance report, is available on the Rand Water website at https://www.randwater.co.za/DMTNdocuments.php. The Sustainability Performance Targets for key performance indicator's (KPI's) Access to potable water and Gender Equality were achieved. However, the Renewable Energy key performance indicator was not satisfied. This is due to the challenges faced in respect of the conclusion of the award for the photovoltaic tender, and Rand Water has since made necessary efforts within our supply chain management process regarding the conclusion of this tender. Accordingly, the step-down margin will not be applicable. The applicable margin for RWL26 will remain at 2.25%, and the interest rate for RWL28 will remain at 9.705%. 20 November 2023 Debt Sponsor Nedbank Corporate Investment Banking, a division of Nedbank Limited Rand Water information: 522 Impala Road, Glenvista, 2058, Johannesburg, Gauteng, South Africa PO Box 1127, Johannesburg, 2000 www.randwater.co.za For further information, please contact: Lucky Ncobela, Debt Officer 083 212 0706 Date: 20-11-2023 05:30:00 Produced by the JSE SENS Department.
