EBITDA also increased 6.2% to €475m (£343m), equating to 8.4% of overall revenue.
Philippe Salle, chairman and CEO of Elior Group, said: “In FY 2014-2015, we not only met all of the objectives we set ourselves but actually exceeded them, with organic growth coming in at 3%.
“This clearly demonstrates the underlying strength of our business as well as our ability to seize growth opportunities while safeguarding our profit margins. During the year we carried out several acquisitions and launched our 2016-2020 strategic plan aimed at accelerating the Group’s development.
“We expect to start reaping the benefits of this plan as from FY 2015-2016, generating profitable growth that will place us firmly on the path towards achieving our 2020 ambitions.”
Contract catering and services revenue rose €222m (£160m), or 5.9%, to €4bn (£2.89bn) and accounting for 70% of total consolidated revenue. New contracts included St Albans Cathedral in the UK and Los Angeles Airport in the US.
The year also includes the acquisition of UK-based Lexington which added 0.8% to revenue growth and had a €51m (£36.8m) positive effect.
Concession catering revenue also advanced by 7.1% to €1.68bn (£1.21m), representing 30% of total revenue.
The Group expects organic growth to increase by more than 3% and EBITDA margin rates to rise above 8.6% in the next financial year.
