Microlise said it had responded well to the cyberattack on some of its systems last year and that it had fully restored its network within two-and-a-half weeks.
The company said it had won 51 new customers in the period following the attack and had not lost any existing business.
Microlise added that as a result, it expected EBITDA to be slightly ahead of market expectations at £11.3m.
The cyberattack occurred on 31 October and left DHL’s store deliveries for retailer NISA disrupted after its delivery tracking system was disabled.
Microlise said it immediately took action to limit the impact of the incident and due to its investment in “enhanced security measures surround customer data”, the company ensured no customer systems data was compromised.
It is currently assessing the exceptional costs associated with the attack and has made a claim for the costs in full.
The comments came in a trading update from the telematics firm for the year ending 31 December 2024.
Microlise said it had delivered a strong performance, with recurring revenue growth of 21.4% to £54.7m.
Non-recurring revenues decreased by 1.4% to £26.3m, which it said was primarily due to a slowdown in OEM sales in the second half of the year, which is expected to return to normal levels this year.
Nadeem Raza, Microlise CEO, said: “The business responded well to the cyber incident in October, resulting in minimal impact to the forecast FY24.
“I would like to thank all our staff for their hard work and dedication in restoring services for our customers, and our customers for their patience and understanding during this period.
“The outturn for 2024 shows a strong business with a healthy pipeline and puts us in a great position to take advantage of opportunities in 2025.”
