In the year to June 2021, Robertson Group returned to more normalised trading lifting pre-tax profit to £17m from £1.2m in the previous 15-month period.

Group operating margins returned to 2.5% after operating profit rebounded to £15m from a £6m loss previously.

Elliot Robertson, chief executive officer, said the business was well-positioned to grow further after revenue climbed back to £588m last year.

He said: “The Group has illustrated its strength in the marketplace and the resilience of its teams to deliver a strong set of results and quality of earnings in what continues to be challenging times for both our industry and the wider economy.

“Having taken the decision last year to extend our reporting period by three months we have been able to provision for the challenges imposed by covid-19 and position ourselves well for recovery.

“We are challenged by the current climate of price inflation and material and labour availability however through our strong supply chain partnerships and our ongoing commitment to developing our talented people, together with rewards, and retention strategies, we are resolute in our confidence that the year ahead will have positive outcomes for the business.”

Net cash at year-end improved to £74m from £34m the year before.

Robertson Construction delivered robust trading with turnover of £462m. The regional contracting arm completed an £87m project for Boeing to provide new hangar facilities at RAF Lossiemouth to house the new fleet of Poseidon aircraft and a £53m community campus at Inverurie.

Elliot Robertson added that its Capital Projects arm was making real progress with Clear Futures – a 25 year Strategic Partnering Agreement designed to help public sector bodies decarbonise.

Robertson Facilities Management continued to form a core part of the group’s growth and value strategy, delivering FM solutions across the UK with turnover growing around a quarter to £94m and employing over 1,400 people from staff at 2,600.
