Rockdale Facility 400 MW expansion completion
Company: Riot - Project: Rockdale
What the later record shows
Delivered; the record does not say when
A December 2025 prospectus says the roughly 400 MW Rockdale expansion was finalized, bringing capacity to 700 MW. The 10-K shows 630 MW at end-2022 and 700 MW at end-2023, so it was done during 2023. No passage says whether that was by March 31, 2023.
