The data-centre builder Winthrop Technologies says it has an “exceptionally strong order book for 2026 and beyond” after pre-tax profits last year rose by 27pc to €131m.

New consolidated accounts for the Dublin-headquartered firm show that revenues rose by 27pc from €1.1bn to €1.4bn. The revenue and profit increase comparisons are somewhat skewed as the prior reporting period was for eight months.

The directors state that the group retains a strong-cash generating capability. In terms of future developments that will affect the group, the directors point to the impact of AI (Artificial Intelligence).

The directors state that they look forward to further strong growth as a result of the excellence of Winthrop’s delivery and “growing demand in the industry arising from ongoing escalation in cloud-based demands and the emergence of Al-related requirements”.

The group last year recorded post-tax profits of €112.3m after incurring a corporation tax charge of €18.69m.

The directors state that the business continues to expand across Europe with key strategic clients, and is currently active in eight jurisdictions. The firm’s website lists data centre projects in Dublin, Frankfurt, Warsaw, Amsterdam along with a number in locations in Finland.

The directors state that earnings before interest tax depreciation and amortisation (EBITDA) increased by 36pc or €36.4m from €102.4m to €138.8m in 2025. This was a reflection of the “ongoing robust profitability of the principal business of the group”.

It paid out a dividend of €927,000, a small fraction of the €94.6m dividend paid out in 2024.

Two years ago Blackstone, the world’s largest alternative asset manager, acquired a 50.7pc stake in Winthrop Technologies. The remainder of the shares are held by founder Barry English; group chief executive Anne Dooley, and managing director Bernard Keane.

A mechanical engineer, Ms Dooley joined Winthrop Technologies in 1997 during its start-up phase.

Numbers employed by the group last year increased from 692 to 724 as staff costs rose by 57pc from €66.26m to €104m.

The profits take account of non-cash depreciation costs of €7.98m.

Pay to directors increased by 21pc from €1.96m to €2.38m, including €79,000 in pension contributions. Key management personnel last year shared €3.03m compared to €2.77m in the prior eight-month period.

Shareholder funds last year increased from €199.39m to €310.89m that included accumulated profits of €271.23m. Cash funds increased from €119.64m to €210.4m.
