Marks & Spencer reported a 24% [1] decline in annual profit following a cyber attack that disrupted its online clothing sales.
The financial hit underscores the vulnerability of major retail infrastructure to digital disruptions. As companies increasingly rely on e-commerce for growth, a few days of downtime can result in millions of pounds in lost revenue and a significant impact on yearly earnings.
The profit slide was detailed in financial results released this week. The company said the loss was due to a cyber attack that occurred over the Easter weekend from April 18 to 21, 2025 [2]. During that period, the attack halted online clothing sales, which directly cut revenue and pressured the bottom line [3].
Despite the decline, the retailer said it has emerged stronger from the incident. Management expects profit growth to return as the company moves past the disruption. The company has focused on recovering from the hit and improving its resilience against future digital threats.
The incident occurred during a critical shopping window. By shutting down the online clothing portal for four days, the retailer missed significant consumer demand during a holiday period, a gap that proved too large to close within the fiscal year.
Marks & Spencer is now positioning the event as a catalyst for operational improvement. The company said it has made progress in its recovery and expects a boost in profits moving forward as it stabilizes its digital operations.
“Annual profit declined by 24%”
This event highlights the systemic risk that cyberattacks pose to the 'just-in-time' nature of modern retail. When a primary sales channel like an online clothing store is disabled, the lack of immediate redundancy can lead to a permanent loss of seasonal revenue that cannot be recovered through later promotions, directly impacting annual profit margins.
