In the first three months of the year, total revenues were up 4.8% compared to the same period of 2018.
Revenue in its secure solutions division, which provides security guards for The Open golf championship, climbed 4.9% year-on-year, driven by a strong performance in Africa and the Americas.
As for its cash solutions business, which transports and stores money on behalf of customers, revenues grew by 4.4%. Much of the growth came from North America, where sales jumped by a third.
The plan is to spin off that side of the group, and boss Ashley Almanza said “good progress” was being made with the separation review.
He added: “Our sales wins in the second half of 2018 provided a good start to 2019 and the group’s revenues were 4.8% higher than the first quarter of last year, with growth in all regions and divisions.
“This momentum, together with growing technology-enabled services in both our cash and security businesses, underpins a positive outlook for the group.”
Shares in the FTSE 250 company, which is being targeted by Canadian group Garda World, rose 2.4% to 235.2p in morning trading on Tuesday.
