What the later record shows
Delivered on time · happened June 30, 2025
The 2025 10-K says bitcoin mining began at Black Pearl in June 2025, which means the site was at least partly energized within Q2 2025 as promised. Energization itself is inferred from the start of mining rather than stated directly.
“We commenced mining bitcoin at the Black Pearl data center in June 2025 and ramped up to 150 MW of capacity by September 2025.”
