Dividend Declaration

21 October 2021

Secure Income REIT Plc (AIM:SIR)

(the "Company")

Quarterly dividend rate maintained

The Board of Secure Income REIT Plc, the specialist long term income REIT, today declares an interim quarterly dividend of 3.95 pence per share in respect of the year ending 31 December 2021, in line with the dividend guidance provided in the 2020 Annual Report.

As previously announced, the quarterly dividend increased by 8.2% from 3.65 pence per share to 3.95 pence per share in July 2021 and the quarterly dividend is expected to remain at this level for the first two quarters of 2022.

All rents receivable are contracted to return to their pre-Covid trajectories once the remaining rent concessions expire within the next three months. With 58% of rental income derived from leases with upward only RPI linked rent reviews, 41% subject to fixed uplifts and 1% to open market review, and following the very high rent collection rates experienced to date, the Board remains confident the business is well positioned to deliver rental income growth.

Dividends will be payable on 3 December 2021 to shareholders on the register on 29 October 2021 and the ex-dividend date will be 28 October 2021. The dividend will be paid as a Property Income Distribution in respect of the Company's tax-exempt property rental business.
