Improving trading conditions at major UK grocers are beginning to reshape the outlook for supermarket real estate, which could benefit Supermarket Income REIT PLC (LSE:SUPR, OTC:SUPIF).
In a note responding to recent Christmas updates from Tesco and Marks & Spencer, Panmure Liberum said the evidence points to a structural improvement in supermarket profitability.
That shift is increasingly relevant for landlords such as SUPR, because tenant margins, rather than headline sales, determine how much rent a store can sustainably support.
Both retailers reported positive like-for-like growth and further market share gains over the festive period.
Tesco recorded its highest UK market share in more than a decade alongside improving free cash flow, while M&S Food delivered 5.6% like-for-like growth, with volumes outperforming the market and sharply lower waste and markdowns.
Panmure said this reflects years of tighter pricing discipline, better product mix and improved cost control.
The broker argues that the sector’s reliance on rent-to-sales ratios risks understating rental headroom when margins are rising.
Even with flat sales, higher operating profits can support higher rents, particularly in prime, high-density locations. Early signs of this are emerging, with supermarket assets delivering around 9% total returns over the past year, helped by a modest uplift in rental values.
Index-linked income remains the core attraction for Supermarket Income REIT. Any margin-led rental growth is seen as a medium-term upside rather than a base-case assumption.
Panmure adds that the strongest opportunity lies in smaller-format stores, where competition is intensifying and rental sustainability appears greatest.
