Marks & Spencer anticipates a £300 million hit to its operating profits for the 2025/26 financial year due to an ongoing cyberattack, which has caused significant disruption to its operations and online sales. Despite the challenges, CEO Stuart Machin emphasized the company's commitment to recovery and long-term growth, viewing the incident as an opportunity for transformation. Customer data was compromised in the attack, attributed to the ransomware group Scattered Spider, although sensitive payment information was not affected.
