Sisk recorded turnover of €1.379bn from its Irish operations in 2025 as strong construction activity across data centres, life sciences, advanced manufacturing, pharmaceuticals, commercial development, residential and civil engineering supported its domestic business.
The Irish performance forms part of a stronger profitability result for Sicon Limited, the parent company of John Sisk & Son’s construction and related businesses across Ireland, the UK and mainland Europe.
Group profit before tax increased by 27.7% to €74.2m for the year ended 31 December 2025, while operating profit rose by 37.9% from €48.6m to €67m.
The improvement in earnings came despite a reduction in overall turnover. Group revenue was €2.624bn in 2025, down 4.7% from €2.752bn in 2024.
Gross margin increased from 6% to 7.6%, a rise of 1.6 percentage points. Sisk attributed the stronger profitability to improved operational performance and a disciplined approach to project selection and profitable growth.
More than 90% of Group turnover was generated by contracting and related activities. The reported figures also include Korine Property Partners, Sensori Group, Sisk Rail, Vision Built and Origo Distribution.
Ireland accounted for approximately 53% of total Group turnover during the year, maintaining its position as a major market for the construction group.
Sisk said its Irish operations benefited from high levels of activity across public and private sector markets, with its project pipeline spanning major areas of capital investment and economic infrastructure.
Projects highlighted by the contractor during 2025 included The Frame on Baggot Street in Dublin, the Adare Bypass in Co Limerick, AstraZeneca’s development at Ballycoolin in Dublin, University Hospital Limerick and the Bon Secours Hospital development in Limerick.
The results also show a substantial liquidity position entering 2026. Sisk held €338.1m in cash at the end of 2025 alongside €54.2m in short-term investments, bringing combined cash and investments to €392.3m. The Group reported no debt at year end.
Sisk also expanded its infrastructure operations during 2025 through its acquisition of Farrans Limited in October.
Farrans continues to operate as a standalone business within the wider Group and gives Sisk additional civil engineering and infrastructure capabilities across Ireland, Northern Ireland and Great Britain. Its areas of expertise include water, energy, transport, aviation and marine infrastructure.
Sisk CEO Paul Brown said the Group had experienced increased profitability and improved margins while strengthening its position in key markets.
“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,” he said.
Mr Brown said the Farrans acquisition had broadened Sisk’s operations and strengthened its infrastructure and civil engineering capability across Ireland and the UK.
The Group also reported continued activity in Britain during 2025 across residential, commercial, infrastructure and specialist rail projects. Major projects included the Etihad Stadium expansion in Manchester, Silvertown in London, Wembley Park, Moderna in Oxfordshire and York Central.
Across mainland Europe, Sisk remained active in the Netherlands, Sweden, Belgium, Germany and Denmark, with its operations concentrated on mission-critical projects for multinational clients across data and ICT, life sciences and advanced manufacturing.
The contractor enters 2026 with an advance order book valued at €7.2bn and said a significant proportion of its planned workload for this year is already secured and underway, with visibility extending into 2027.
Its target sectors include infrastructure, healthcare, energy, data centres, life sciences, advanced manufacturing, high-rise residential and other complex construction projects.
For the Irish construction market, the combination of €1.379bn in domestic turnover, the Farrans acquisition and Sisk’s wider €7.2bn forward order book points to continued exposure to some of the State’s largest areas of planned capital investment as the Group moves through 2026.
