The Interim 2025 Dividend is payable on Thursday, 16 October 2025 to shareholders registered on the UK principal register ("UK Shareholders") and the South African branch register ("SA Shareholders") who have elected to receive the dividend in cash. The Record Date for both UK Shareholders and SA Shareholders is at the close of business on Friday, 5 September 2025. The DRIP purchases settlement date (subject to market conditions and the purchase of shares in the open market) is Monday, 20 October 2025 in the UK and Thursday, 30 October 2025 in South Africa. The Interim 2025 Dividend should be regarded as a "foreign dividend" for SA income and SA dividend tax purposes and the funds will be paid from the United Kingdom.

Cash PIDs The information below is intended as a general guide only and is based on Hammerson Plc's understanding of the law and practice currently in force. Any shareholder who is in any doubt as to their tax position should seek independent professional advice. The Interim 2025 Dividend should be regarded as a 'foreign dividend' for SA income tax and dividends tax purposes. A 20% UK withholding tax is applicable to the Interim 2025 dividend as it will be paid as a PID. After payment of the PID South African shareholders may apply to HMRC for a refund of the difference between the 20% UK withholding tax and the UK/South African Double Tax Treaty rate of 15%, i.e. 5% of the tax withheld. The Interim 2025 cash dividend will be exempt from SA income tax but it will be subject to SA Dividends Tax as it will be declared in respect of a share listed on the exchange operated by the JSE. SA Dividends Tax will apply to the Interim 2025 cash dividend, at a rate of 20%, unless the beneficial owner of the dividend is exempt from SA Dividends Tax or qualifies for a reduction of the SA Dividends Tax liability to 5% (if they can claim a credit for the effective 15% UK withholding tax suffered against the 20% SA Dividends Tax rate). The applicability of the exemption or reduced rate will be subject to the prescribed requirements for effecting the exemption or reduction being in place by the requisite date. Shareholders electing the DRIP Partial elections are not permitted under the DRIP. SA Shareholders electing the DRIP should note that, in respect of fractional entitlements that may arise, all allocations of shares will be rounded down to the nearest whole number, and any residual amounts that are not used to reinvest in shares (as a result of rounding down) will be paid out to these SA Shareholders in cash. It is the Company's understanding that the residual cash paid to SA Shareholders who have made DRIP elections would already have been taxed prior to the calculation of the number of shares and any residual cash owing to such SA Shareholders. Accordingly, no further tax should be payable on the cash paid to SA Shareholders as a result of any fractional entitlements. The above information and the guidelines on the taxation of dividends are provided as a general guide based on the Company's understanding of the law and practice currently in place. Any shareholder who is in any doubt as to their tax position should seek independent professional advice.
