Stirling-based construction, development, infrastructure and support services firm Robertson Group said its revenue rose almost 5% to £616 million while profit before tax increased 21.3% to £20.5 million in the 12 months to June 30, 2022.

The family-owned company said Robertson Construction Group delivered revenue of £460 million and Robertson Facilities Management contributed revenue of £118 million.

Robertson Group CEO Elliot Robertson said: “The group continues to deliver improvement in line with our long-term strategy.

“We are pleased with a strong set of results in a challenging market, delivering quality of earnings, which builds on the progress made last year and reflects the diversity of our offering and strength in the marketplace.

“We operate in a highly competitive marketplace where quality product and services delivered on time and to budget are imperative and one of our key differentiators.

“The current social and economic climate continues to be challenging for the sectors we operate in due to labour availability, and unprecedented levels of inflation across materials and energy.

“However, our strong relationships with our customers and supplier base, enables us to collaborate with our stakeholders to deliver the best outcomes for all concerned.

“Our family of businesses comprises a diverse portfolio of infrastructure-based product and service solutions, producing a mix of long and short-term cash flows, profits and investments creating value and opportunity from the broad offering we give to our markets.

“Our outlook is healthy, and going forward we will continue to provide the best solutions to meet the needs of our customers, while focussing on our people, supply chain, innovation, sustainability and productivity.”
