VSG employs around 6,000 employees, who service more than 1,400 guarding locations, while the company’s security systems are used at over 5,000 locations across the UK and Ireland.
The acquisition will add to Mitie’s existing security arm, which accounts for around a quarter of the group’s annual revenues.
“As a core part of Mitie, our security business has delivered a strong performance over the last three years, with sales growing by over 30%,” said chief executive Phil Bentley.
“This acquisition gives us the leadership position we seek to maximise value from our technology-led solutions.”
In the year ended September 30, VSG reported revenue of £192.1mln and losses before tax of £2.7mln. Those same accounts showed it had £42.4mln worth of assets.
Despite last year’s loss, Mitie expects the division will report “modest profitability” in its next set of results.
Peel Hunt analyst Christopher Bamberry noted that the acquisition "will offer opportunities to accelerate the growth of Mitie's premium technology-enabled security services".
Bamberry maintained his 'hold' recommendation and 165 price target.
Mitie shares opened higher on Monday before falling back and are currently flat at 14.1p in early afternoon morning, while Compass’ stock has nudged 0.5% higher to 1,603p.
