NOTICE OF DIVIDEND CURRENCY EXCHANGE RATE (SOUTH AFRICAN RAND) AND TAX
IMPLICATIONS FOR SOUTH AFRICAN SHAREHOLDERS

On 8 October 2026 the Company announced the declaration of an interim dividend in respect of the period
from 1 July 2026 to 30 September 2026 of 1.575 pence per ordinary share (“First Quarterly Dividend”),
which will be paid by way of a Property Income Distribution (“PID”) on or around 27 November 2026
(“Dividend Payment Date”) to shareholders on the register as at Friday, 30 October 2026 (“Record Date”).

The First Quarterly Dividend will be paid in British pound sterling (“GBP”) to shareholders on the UK register
(“UK Shareholders”) and South African Rand (“ZAR”) to shareholders on the South African register (“SA
Shareholders”). SA Shareholders are advised that the currency exchange rate applicable to the First
Quarterly Dividend payable in ZAR will be 22.02190 ZAR to 1 GBP (“Exchange Rate”), resulting in a gross
local dividend amount of 34.68449 ZAR cents per share. The date on which the GBP payment will be
converted to ZAR is Thursday, 22 October 2026.

To facilitate settlement of the First Quarterly Dividend to shareholders on the South African share register,
shares cannot be moved between the South African share register and the UK share register and no such
transfers of shares between the South African share register and the UK share register shall be registered,
between the Wednesday, 21 October 2026 and Friday, 30 October 2026 (Record Date) both days inclusive.

As at 8 October 2026, the issued share capital of the Company consisted of 1,366,721,113 ordinary shares.

The First Quarterly Dividend should be regarded as a ‘foreign dividend’ for South African income tax and
dividends tax purposes and the funds will be paid from the United Kingdom.

Accordingly, shareholders will be paid a cash dividend per share as follows:

     Less effective 5% SA dividends tax for SA Shareholders
                                                                                 N/A
     who are SA tax residents***                                                                      1.73422

*      Certain categories of UK Shareholders may apply for exemption, in which case the PID element will be paid gross
       of UK withholding tax.
**     Net position after deducting UK withholding tax for both UK and SA Shareholders, but before qualifying
       SA Shareholders who are SA tax residents have claimed back 5% from His Majesty’s Revenue & Customs under
       the double tax agreement between the United Kingdom and South Africa in respect of the UK withholding tax.
***    SA dividends tax applies at the rate of 20% for qualifying SA Shareholders who are SA tax residents, but such SA
       Shareholders receive a rebate of the UK withholding taxes suffered (which is effectively 15%, after taking into
       account the 5% rebate referred to in **).
