After building a strong presence in Scotland over recent years the construction contractor has extended south and is now a player in the London market after securing several projects in the last 12 months.
Pre-tax profits at the group holding company soared from £7m to £17m helped by an £8m profit from the sale of several PFI school investments in Northern Ireland.
Also the main contracting business Graham Construction more than trebled pretax profits to £8m on turnover slightly ahead at £438m in the year ending March 2016.
This improved performance saw construction operating margins recover to 1.8% from 0.5% the previous year, swelling cash to £21m.
Staff headcount rose 6% over the year to top 1,000 employees at the main contracting arm.
The separate asset management business, which now employs around 750 staff, lifted turnover 13% to £70m, generating a pre-tax profit of £3m.
“The group has considerable financial resources together with long term contracts with a number of customers and suppliers across different geographic areas and industries”, said group finance director Courtney McCormick.
“As a consequence the directors believe that the group is well placed to manage its business risk successfullly despite the current uncertain economic outlook.
“Overall, our group businesses continue to deliver robust performances in a market that shows strong signs of growth, with investment in infrastructure a key focus area for both the public and private sector.”
He added: “Our four main business units provide us with a well-balanced service offering within the group, and are all underpinned by a healthy forward order book.
“We are encouraged by the continued development of our asset management business and believe its success in generating long term partnerships with clients, coupled with its continued service diversification, investment in new technology and regional growth, leave it with a strong platform for sustained growth.”
Executive Chairman, Michael Graham added: “This is a significant milestone for Graham and one which demonstrates how our Group businesses continue to deliver exceptionally strong performances, across a range of sectors, throughout the UK and Ireland.
“None of this would be possible without the dedication and commitment of our 1,800 strong workforce, on which Graham’s success is built.
“Knowing that they are trusted and their efforts valued, creates a high performance culture and it is no coincidence that Graham has become known as one of the most attractive employers in the industry.
“By keeping business simple, being efficient and effective in all that we do and with a forward order book of almost £1bn, Graham is well positioned to continue its growth from a position of strength.”
