What This Means
M&S experienced a prolonged disruption from a cyber-attack that took more than twelve months to fully resolve, yet the retailer has returned to profitability at £355m. The extended recovery period underscores the operational and financial toll of major cyber incidents on large retailers, affecting inventory systems, sales channels, and customer operations during the outage window. Cyber resilience and incident response capacity now factor into investor assessment of retail operational risk.
