How we checked this
Checked on September 13, 2026. The cited source supports every part of this claim.
The 10-Q says the retrofit is already in progress and phased delivery is expected to begin in 2026. The claim's wording blurs the two, but the substance matches. A later section says a July 2026 lease amendment moved first capacity delivery to about July 31 or early August 2026.
Confirmed in the source:
- The Black Pearl Facility is being retrofitted for an HPC tenant
- Phased delivery of the Black Pearl Facility is expected to commence in 2026
