Sisk CEO, Paul Brown, said: “2025 was another strong year for Sisk. We experienced increased profitability, improved margins, and continued to strengthen our market positioning in our key market sectors while maintaining a disciplined approach to growth and investment.

“Our performance in the year reflects the quality of our order book, the expertise of our teams and the consistent focus across the business on disciplined growth, innovative delivery excellence and a focus on improving our quality of earnings.

“We also welcomed Farrans to the Group during the year, broadening our  base and further strengthening our infrastructure and civil engineering capability across Ireland and the UK.

“With a strong balance sheet, no bank debt and good pipeline visibility across our markets, we have entered 2026 in a strong position.

“Demand remains positive in most of the sectors in which we operate, and we remain focused on delivering sustainable growth while continuing to create long-term value for our clients, partners and communities.”

Looking forward the firm said: “Sisk will continue to focus on the sectors where it can deliver long-term value and leverage its technical expertise, including infrastructure, healthcare, energy, data centres, life sciences, advanced manufacturing, high-rise residential and complex construction.

“As investment continues across these sectors, Sisk is well positioned to support clients in delivering critical projects while pursuing sustainable and profitable growth across its core markets.”
