Where it stands

Barber Lake is a 300 MW gross HPC data center near Colorado City, Texas, leased to Fluidstack with a Google backstop. Phase I is 244 MW gross (168 MW critical IT) and Phase II is 56 MW gross (39 MW critical IT). The September 2026 amendment moved delivery to individual data halls between Q4 2026 and Q1 2027, with first rent expected in Q4 2026; no passage confirms any hall has been delivered yet. The phase dates shown are the original 10-K targets, which the amendment has superseded.
