Mitie chief executive Ruby McGregor-Smith said: "Mitie has had a positive start to the year. Our focus on the services sector, primarily in facilities management, will ensure we continue our long-term track record of sustainable profitable growth.
"We are the market leader in integrated FM and are particularly pleased with recent contract awards and retentions. This gives us confidence we will deliver a good full-year performance."
Mitie added: "Our landscaping business is performing well and has successfully mobilised its largest ever account, with Jones Lang LaSalle as part of Mitie's broader bundled services contract.
"It has also re-launched its offering, with a motto that 'first impressions count' and a focus on its broader horticultural credentials. There is a good pipeline, particularly in the property sector, and we are seeing the size of the potential opportunities grow quite significantly from a few years ago."
Contracts included a £40m five-year contract with Thales including landscape maintenance and a three-year contract with NEC including landscape maintenance.
