JOINT VENTURE PORTFOLIO UPDATE

Supermarket Income REIT plc (LSE: SUPR), the real estate investment trust providing secure, inflation-protected, long income from grocery property in the UK, announces an update in relation to its 50:50 joint venture with British Airways Pension Trustees Limited (the "JV").

The JV has a 51% beneficial interest in the Sainsbury's Reversion Portfolio (the "Portfolio"). The remaining 49% beneficial interest is held by Sainsbury's⁽¹⁾. The Portfolio consists of the freeholds to 26 Sainsbury's supermarkets.

The Company announces that Sainsbury's has exercised a purchase option to acquire 13 stores within the Portfolio. Sainsbury's acquisition of the 13 stores will be completed in March 2023 upon expiry of the current occupational leases. The purchase price under the option is to be determined based on the assumption of a new 20-year lease to Sainsbury's with the initial rent set at the higher of passing or open market, subject to upward-only, five yearly market rent reviews.

In addition, Sainsbury's has a remaining purchase option to acquire a further 10 stores in the Portfolio, which can be exercised between December 2021 and January 2022.

Ben Green, Director of Atrato Capital Limited, the Investment Adviser to Supermarket Income REIT plc, said:

"Sainsbury's decision to buy back these stores is further evidence of the strength of demand for grocery property in the UK and also demonstrates the balance sheet strength of the supermarket operators. The exercise of this first tranche of options is expected to generate a positive NAV impact for Supermarket Income REIT."
