CONSTRUCTION STATUS
Apr 6, 2026

The first array of dry cooling air-cooled condensers for Building 1 has been completed and is operational. A second array, with larger fans, is about halfway complete (located to the south of the first array). More chillers have also been added. For Building 2, an array of dry cooling air-cooled condensers of the same type as Building 1's first array is beginning construction. We believe this corresponds to the "second cluster of 110,000 GB300 processors and 220 megawatts of compute power" from the company S-1 filing, page 76, with compute power corresponding to GPU server power. This is also consistent with our estimates based on cooling equipment.
