Winthrop Technologies Limited (“Winthrop Technologies”), Europe’s leading dedicated turnkey data centre delivery provider, has announced a strategic partnership with funds managed by Blackstone Tactical Opportunities and affiliated funds (“Blackstone”).

As part of the transaction, Blackstone will acquire a 50.7% stake in Winthrop Technologies with the remainder of the shares held between the existing shareholders, founder, Barry English; Group CEO, Anne Dooley; and Managing Director, Bernard Keane. Financial terms were not disclosed.


The partnership is set to accelerate Winthrop Technologies’ growth trajectory, allowing it to capitalise on the ongoing demand for data centres, the critical infrastructure behind the digital economy.

Blackstone is aligned with Winthrop Technologies’ growth mindset and will support Winthrop in delivering its current business strategy, continuing additional recruitment for high-quality roles to support projects in Ireland and across Europe.

Anne Dooley, Winthrop Technologies Group CEO, said: “The partnership with Blackstone marks a new era of growth for Winthrop Technologies.
