Empty shelves, empty coffers: Co-op pegs cyber hit at 80m

"Today it said the breach, which struck in April and forced it to shut parts of its IT systems, has so far cost it £206 million in lost revenue, with Co-op taking an £80 million profit hit in the first half of 2025. As a result, Co-op slumped to an underlying operating loss of £32 million, a sharp swing from the £47 million profit it notched up a year ago."

"If Co-op did pay a ransom to criminals, it didn't do much good. Co-op confirmed in July that attackers had stolen the personal details of all 6.5 million of its members, including names and contact information, although the company said no payment card or transaction data was compromised. Co-op insists its defences stopped the attackers before they could unleash full-blown ransomware across its production systems, sparing it from an even bigger shakedown."

The Co-operative Group suffered a cyberattack in April that forced shutdowns of parts of its IT systems. The group reported £206 million in lost revenue and an £80 million profit hit in the first half of 2025. The breach turned a prior £47 million profit into an underlying operating loss of £32 million. The reported losses include an unexplained £20 million one-off payment. Attackers stole personal details of all 6.5 million members, though payment card and transaction data remained uncompromised. Supply chains jammed, some shelves went bare, and back-office operations seized up. The breach triggered regulatory investigations and membership discounts were offered.
