Hammerson plc (Incorporated in England and Wales) (Company number 360632) LSE and Euronext Dublin share code: HMSO JSE share code: HMN ISIN: GB00BK7YQK64 (“Hammerson” or “the Company”) THIS ANNOUNCEMENT (AND THE INFORMATION CONTAINED HEREIN) IS NOT FOR RELEASE, PUBLICATION, DISTRIBUTION OR FORWARDING, DIRECTLY OR INDIRECTLY, IN WHOLE OR IN PART, IN, INTO OR FROM ANY JURISDICTION WHERE TO DO SO WOULD CONSTITUTE A VIOLATION OF THE RELEVANT LAWS OR REGULATIONS OF SUCH JURISDICTION. FOR IMMEDIATE RELEASE Interim 2022 Dividend and Enhanced Scrip Dividend Alternative Cash Fraction Applicable to the Enhanced Scrip Dividend Alternative 6 October 2022 Further to the announcements released on 28 July 2022, 27 September 2022, and 28 September 2022, Shareholders are further advised of the below. Fractions applicable to the Enhanced Scrip Dividend Alternative: Shareholders on the UK Register No fraction of a New Share will be issued to Shareholders on the UK Register. Entitlements to New Shares of Shareholders on the UK Register who elect for the Enhanced Scrip Dividend Alternative will be rounded down to the nearest whole number of New Shares. Entitlements to fractions of New Shares will be paid to Shareholders who elect for the Enhanced Scrip Dividend Alternative in cash based on the value of the Enhanced Scrip Dividend Alternative. Such entitlements will be paid in the same way as the cash dividends are paid for the Interim 2022 Dividend. Shareholders on the South Africa Register No fraction of a New Share will be issued to Shareholders on the South Africa Register. Shareholders on the South Africa Register cannot accumulate residual entitlements or receive a fraction of a New Share. Where you have made an election to participate in the Enhanced Scrip Dividend Alternative, which would otherwise give rise to an entitlement to a fraction of a New Share, the number of New Shares to be received will be rounded down to the nearest whole number of New Shares, and any residual entitlement which is less than the price of one New Share will be paid to you in cash in Rand. The cash fractional payment for Shareholders on the South Africa Register is to be determined with reference to the volume weighted traded price on the Johannesburg Stock Exchange (“JSE”) on Wednesday, 5 October 2022 (being the date on which the Shares began trading on the JSE ex the cash dividend or Enhanced Scrip Dividend Alternative) of 385.00 ZAR cents, discounted by 10% (“South Africa Fractional Reference Price”). Shareholders are accordingly advised that the South Africa Fractional Reference Price is 346.50 ZAR cents (385.00 ZAR cents discounted by 10%). South African Taxation The cash fractional payment is regarded as a dividend for South African tax purposes and will be subject to dividends tax to the extent that it is declared in respect of a share listed on the JSE. South African Dividends Tax at the rate of 20% will be withheld from such cash dividends paid to individuals, therefore the net fractional rate will be 277.20 ZAR cents. Shareholders are advised to seek their own tax advice from an independent tax adviser should they be in any doubt as to the tax treatment for them of any cash fractional payment. A summary of how UK Shareholders and South Africa Shareholders are likely to be treated for tax purposes is set out in Section 2 of the Guide containing the terms and conditions of the Enhanced Scrip Dividend Alternative, which is available on the Company's website, https://www.hammerson.com/investors/dividend/scrip-dividend.
