Darker bar: ahead of the other company on that measure.
Pure DC is a hyperscale developer across Europe and the Middle East whose Finnish campus is the largest single project in this registry. SJK01 at Seinäjoki spans 370 acres with more than 550 MW of planned IT capacity and over EUR 7.5 billion of total investment, one of Finland's largest ever inward investment projects and the largest by a UK company there. Phase 1 is 110 MW at over EUR 1.5 billion and, critically, already fully leased, with planning permissions, power requirements and the first substation in place, which separates it from the many announced campuses still dependent on customer commitments. Microsoft has reportedly signed as anchor tenant. The design is repeatable 40 MW AI-ready modules with direct-to-chip liquid cooling, closed-loop with zero operational water use and waste heat into the local district heating network, on more than 700 MVA of renewable power. Financing is the strongest signal: over USD 4.2 billion secured in twelve months, including USD 2.7 billion in May 2026 led by SMBC, Allianz Global Investors and ABN AMRO largely against the Dublin and Amsterdam campuses, then EUR 1.3 billion of committed senior debt on 2026-07-21 for SJK01 Phase 1 across five mandated lead arrangers, executed in six weeks. Technology scores 3 because Pure DC is a developer and operator, not a technology owner.
