Latest results for the year to 31 December 2021 show pre-tax profits more than doubled to £19m from £8.9m and revenue up 10% to 2, £2 billion.
The company now looks forward to a further recovery this year on the back of a record forward order book of £1.6bn, having maintained its zero debt status and improved its net cash position by 18 % to £120m.
Matt Blowers, CEO of ISG, said, “Our strong foundation and continued focus on driving innovation and efficiency has enabled ISG’s business to quickly return to its financial trajectory, characterized by largest futures order book in our history.
He added, “Today, ISG is a resilient company with a unique culture and a clear purpose.
“Our financial strength and our deep foundations as a business mean that we are perfectly positioned to respond to our rapidly changing world and industry.”
Most of last year’s profit growth came from fit-out activity, as the market recovered strongly in the UK.
