What the later record shows
Delivered late · happened March 31, 2026
CB-2 was not online at 2025 year-end (only 18 MW of HPC). Both CB-2A and CB-2B were delivered by March 31, 2026. The company cited tenant fit-out sequencing as the reason for the delay.
“Certain building milestones were sequenced accordingly, and associated timing impacts have been incorporated into the Company’s financial plan.”
