The Co-op has said the cyber attack it suffered earlier this year cost it at least £206m in lost revenues.

The retailer's IT networks were infiltrated by hackers in April, resulted in payment problems, widespread shortages of goods in shops, and the loss of customer data.

Co-op chair Debbie White said the "malicious" attack had caused "significant challenges" in the first half of 2025.

She added the group must now rebuild "better and stronger to meet the challenges and opportunities that lie ahead".

Overall, the retailer reported a £75m underlying pre-tax loss in the six months to 5 July, compared to a £3m profit in the same period a year earlier.

The full cost of the attack could be much higher as the Co-op said it was also expecting there to be some impact to its business in the second half of the year.
