Co-op saw its revenue decline by 2.3 per cent year-on-year to around £11 billion in its full-year results in 2025 after taking a major hit from the cyberattacks.

The retailer posted a full-year loss of £35 million compared to a profit of £131 million in the same period last year.

Co-op was affected by a major £107 million impact from the cyberattack last year as well as an extra £150m cost in headwinds.

According to the business, the additional cost headwinds were due to a rise in National Insurance fees and the new Extended Producer Responsibility charges as well as investments in colleague pay.

The retailer’s pre-tax loss amounted to £126 million, from a £45m profit last year, driven by changing consumer behaviour following the cyberattacks.

Debbie White, chair of Co-op Group, said: “2025 was a challenging year, but those challenges have helped us reshape Co-op for the future. Despite a cyberattack and tough market conditions, our colleagues have shown incredible resilience, keeping communities served and essential services running.

“To get back on track, we have adjusted our commercial strategy and strengthened our partner offer while substantially growing active membership.”

The Group also stated that the protective action from the cyberattack cost £285 million, which negatively impacted overall revenue, and is planning a business recovery for the upcoming year.

Moving forward, the Group expects external challenges such as volatility and weak consumer confidence to continue, but plans to achieve a 35 per cent increase in underlying profit for 2026.

Co-op’s strategy involves a new commercial and logistics business to centralise the buying functions, improving customer experience across all channels and increasing active members to 10 million by 2030. The c-store retailer is also working towards reducing £200 million in yearly operating costs in 2026.

Following the results, Co-op’s CEO Shirine Khoury-Haq has stepped down from the role after seven years, with Kate Allum appointed as interim CEO effective from 30 March.

Allum is currently a member-nominated director on Co-op’s board and will lead the turnaround strategy after the sudden departure of the Group’s CEO.

Khoury-Haq said: “Following last year’s cyber attack, the organisation is now ready to deliver on an ambitious strategy of stabilisation and transformation.

“This extends beyond the timeframe I had planned for my CEO tenure, and now is the right moment to hand over to leadership that can commit to seeing the strategy through.”
