Co-op Group, the Manchester-based member-owned mutual, said the recent cyber attack at the firm damaged its revenue by £206 million and had a profit impact of £60 million in the six months to July 5.

Group first-half revenue slipped 2.1% to £5.484 billion and the Co-op made a first-half loss before tax of £50 million compared to profit of £58 million in the prior year period.

Co-op Group said: “The estimated adverse trading impact to revenue of £206m and associated profit impact of £60m reduces our underlying results.”

In its outlook, Co-op Group said: “We anticipate continued cost headwinds, global volatility and high competition.

“In response, we remain committed to a disciplined approach to investment to support our future, while managing a reducing level of cyber impact through the second half …”

Co-op Group CEO Shirine Khoury-Haq said: “Over the past three years, we’ve built a stronger and more resilient Co-op — one that’s better able to navigate the headwinds that all businesses are facing. 

“When we experienced a significant cyber attack, that financial strength allowed us to respond as a member-owned organisation.

“I’m very proud of how we reacted: we kept trading, prioritised colleagues and vulnerable communities, and launched a partnership with The Hacking Games to tackle youth disenfranchisement — the root of many cyber threats.

 “The cyber attack highlighted many of our strengths. But more importantly, it also highlighted areas we need to focus on — particularly in our Food business.

“We’ve already started on this journey, refining our member and customer proposition, making structural changes to our business, and setting our Co-op up for long-term success.”

With more than 2,300 food stores, 800 funeral homes and a wholesale business supplying around 6,000 additional outlets, Co-op Group employs about 53,000 people.

Co-op Group chair Debbie White said: “The first half of 2025 brought significant challenges, most notably from a malicious cyber attack. Our balance sheet strength and the magnificent response of our 53,000 colleagues enabled us to maintain vital services for our members and their communities. We must now build our Co-op back better and stronger to meet the challenges and opportunities that lie ahead.”
