Three campuses, one region

Vihti is physically separate from Espoo and Kirkkonummi. The municipality explicitly describes the independently functioning locations, supporting three project records without an extra parent-region record.

Land and permit evidence

Vihti reports two plots of about 46 hectares, a EUR12.3 million land deal and a later building-permit notice for Hankasalontie 12. None establishes total campus expenditure.

Investor read-through

Our analysis: permit progression and contractor mobilisation support a delivery-monitoring case, while commissioning remains a separate future checkpoint.

Delivery commitments and dated checkpoints

Target: Regional first-phase construction target around year-end 2026–2027; commissioning follows.

• 2026-04-28: Microsoft identifies three separate campuses and phased delivery; first-phase building work targets the turn of 2026–2027, followed by commissioning preparation. Second-phase permits are issuer-reported. Original company disclosure
• 2026-06-09: DCD separately identifies Espoo, Kirkkonummi and Vihti as developments, while attributing site-progress details to Microsoft. Its Vaasa land acquisition is another project. Independent specialist reporting; construction details attributed to Microsoft

Sources and claim boundaries

Documents are counted as documents, not independent confirmations. Same-issuer releases and their rewrites share an underlying claim. Five documents; two municipal records provide separate land/permit evidence. Microsoft updates are issuer claims; DCD gives outside reporting but not independent metering or a complete permit audit.
