Tesco's UK sales growth slows as Iran war weighs on consumers

Tesco Reports Slower UK Sales Growth Amid Global Uncertainty

By James Davey

First Quarter Performance and Analyst Expectations

LONDON, June 18 (Reuters) - Tesco , Britain's biggest food retailer, reported a slowdown in underlying UK sales growth in its first quarter, missing analysts' average forecast, saying the conflict in the Middle East was continuing to create uncertainty for consumers.

The group, which has an over 28% share of the British grocery market, did, however, maintain its profit guidance for the full-year.

Impact of the Iran War on Retail and Economy

The impact of the Iran war on energy prices, with knock-on effects on consumer spending, is adding to the challenges the UK retail sector and the wider economy face.

UK Like-for-Like Sales and Comparisons

Tesco said UK like-for-like sales rose 1.8% in the 13 weeks to May 30 - below analysts' consensus forecast of 2.3% and compared to growth of 3.1% in the previous quarter.

The group was up against a tough comparative performance in the first quarter last year when UK like-for-like sales rose 5.1%, boosted by favourable weather.

CEO Statement and Profit Guidance

"I am pleased with our progress in the first quarter, with customer satisfaction up strongly and continued sales growth building on the exceptional performance we delivered last year," CEO Ken Murphy said.

Tesco kept its forecast for adjusted operating profit of £3.0 billion to £3.3 billion ($4.0-$4.4 billion) for its year to end-February 2027, versus the £3.152 billion made in 2025/26.

Analysts were on average forecasting profit of £3.25 billion for 2026/27 ahead of Thursday's update.

Share Performance and Consumer Trends

Shares in Tesco have increased 15% over the last year.

UK consumers increased their spending in May after reducing it in April, but expenditure on travel dropped for a third month in a sign of caution over the economic impact of the Iran war surveys showed last week.
