Notes on the record
1-GW HPC/AI development site in Tom Green County, northeast of San Angelo near AEP's Red Creek 345-kV substation (~2,500 ft east of the Skybox San Angelo campus). In November 2025 Cipher purchased a majority interest in a JV (Colchis LLC) to develop the site, with options to buy ~620 acres of land adjacent to the existing substation; Cipher expects ~95% equity subject to final lease/development terms. Coordinates are the NE-San-Angelo / Red Creek substation area centroid (approximate) pending a parcel-level GIS lookup. Investment and jobs figures undisclosed -> omitted. County pinned via local press (San Angelo LIVE); the SEC 10-K discloses only "West Texas.". Cipher Mining was renamed Cipher Digital.
