Following today’s release of Sainsbury’s figures for Q3 and Christmas results for the 16 weeks ending 3 January 2026; Eleanor Simpson-Gould, senior retail analyst at GlobalData, a leading intelligence and productivity platform, offers her view: “Sainsbury’s Christmas performance is on par with Tesco’s, placing both retailers neck-and-neck this festive season. Sainsbury’s total retail sales excluding fuel rose 3.3% for the six weeks to 3 January 2026, narrowly ahead of Tesco’s 3.2%. Sainsbury’s Q3, which includes the six weeks of Christmas, rose 3.9%. Grocery did the heavy lifting at Sainsbury’s and was a clear standout performer, indicating market share gains in the food & grocery sector, while non-food diluted progress. Sainsbury’s shares fell around 5% this morning, signalling investor disappointment that a tougher, more promotional market is still exposing structural weakness in General Merchandise and Argos. Even so, Sainsbury’s still expects retail underlying operating profit above £1bn. However, it needs sharper non-food execution with standout hero lines and a more disciplined price focus during key promotional events.
“Grocery sales grew by 5.4% in Q3 and 5.1% during the Christmas period, outperforming the UK food & grocery market. A focus on value through its Aldi Price Match and Nectar Prices schemes supported basket growth and enhanced sales of premium range products. Fresh food sales rose 8.0% and Taste the Difference fresh food grew 15.0%, backed by more than 260 new Taste the Difference launches, reinforcing that Sainsbury’s is winning both the value shop and the trade-up mission. The supermarket outperformed Tesco’s results, which reported a 6.6% increase in fresh food sales for the 19 weeks ending 3 January, along with a 13.0% uplift in sales of its Finest range. Sainsbury’s must focus on retaining customers through targeted personalisation to engage those who switched to it during Christmas 2025. Additionally, it should enhance its convenience offering, which boosted last-minute Christmas spending in 2025 and improve profit margins by promoting its premium products under the Taste the Difference brand, rather than depending on broad price reductions.
“Non-food remains challenging for the grocer. General Merchandise and Clothing sales fell 1.1% in Q3, and Argos suffered a decline of 1.0%, a disappointing reversal after two quarters of progress in H1 and a sign that Sainsbury’s is not yet structurally competitive in the most promotion-driven gifting categories. The opportunity lies in leveraging existing strengths, such as its improved Tu performance, while making Argos more resilient by refining price architecture and expanding range authority for frequent gifting missions, rather than relying on volatile high-ticket products. Sainsbury’s needs to turn scattered wins in toys, homewares, and electricals into a repeatable proposition with sharper opening prices and fewer but deeper deals on electricals and furniture SKUs.”
