Successful pricing of 7-year GBP250m bond issuance due June 2033

Hammerson announces the pricing of a GBP250m bond with a maturity on 8 June 2033 at 107 basis points over the 4.125% Treasury Gilt 2033 with an annual coupon of 5.875 per cent (the "New Bond"). The issuance was more than four times covered with a peak order book in excess of £1.1bn.

Concurrently with the pricing of the New Bond, the Group has entered into interest rate swaps to convert the 5.875% fixed coupon into a floating rate of SONIA plus a margin of 131 basis points, resulting in a net initial rate of 5.04%. This is in line with the Group's interest rate risk management strategy and reduces the proportion of the Group's gross debt at fixed rates of interest from 95 per cent, reported at its 2026 Half Year Results, to 84 per cent.

The New Bond increases the Group's cash holdings (£500m at 30 June 2026) ahead of the maturity of the Group's EUR700m 1.75 per cent. Sustainability-Linked bond in June 2027.

The Group maintains its FY26 EPRA earnings guidance of c.£132m.
