Cyberattack ate up profits for first half of year, retailer M&S says

Keypoints

• The cyberattack on M&S resulted in a dramatic profit decline for the first half of 2025.
• The company disconnected its warehouse and online systems, causing a months-long disruption.
• Operational systems have now largely been recovered, with insurance helping to soften financial losses.
• Four suspects, including a minor, were arrested in connection with the attacks on multiple UK retailers.
• Competitor retailers like Next have benefited from M&S’s operational setbacks.
