M&S pegs cyberattack cleanup costs at £136M as profits slump www.theregister.com/2025/11/0…
Marks & Spencer says its April cyberattack will cost around £136 million ($177.2 million) in total.
M&S said £83 million ($108.2 million) was spent on “immediate systems response and recovery,” while the other expenses are connected to legal and other professional services.
The retailer said one of the earliest actions it took in its incident response was to disconnect warehouse management systems, which in turn meant online and in-store orders were adversely impacted.
It was forced to introduce manual processes to keep the business running, which led to higher stock management costs and a decline in operating profit margin from 12 percent to 2.7 percent.
