Building 3 (AKA CB5) is operational. On February 26, 2026, Terawulf [stated](https://investors.terawulf.com/news-events/press-releases/detail/132/terawulf-reports-fourth-quarter-and-full-year-2025-results) that CB5 was expected to be energized by Q4 2026. However, based on the pace of Building 2, and comparisons to other projects like Stargate Abilene, we think this is optimistic. We expect a 3-month delay past the end of Q4 2026 to get to full operational capacity.
