Post-completion amortization + 50% excess-cash-flow offers
Terms
$1,400M + $333M add-on; outstanding in full at 6/30/26, with $94.5M classified short-term (scheduled principal due within one year; Q2-26 10-Q). Collateral context (8-K 9/24/26): the Barber Lake lease with Fluidstack was amended. Data halls are now due between Q4 2026 and Q1 2027, with first rent expected in Q4 2026. Cipher bears the first $359.3M of costs above the initial budget. The tenant reimburses 50% of any costs above that amount over the twenty-year term. A leading AI lab, unnamed in the filing, made a binding commitment to a follow-on ten-year lease. That takes the contracted term to twenty years and adds about $5.2B of contracted revenue.

Two Prime Lending Limited
Terms
$100.0M secured credit facility with Two Prime Lending Limited, never drawn and nothing outstanding at 2026-03-31. VERIFIED against the Q1-26 10-Q, which carries a dedicated "Two Prime Lending Facility" note; an earlier suspicion that this row was unsupported or a Hut 8 misattribution was wrong, and Hut 8's separate $200M Two Prime revolver is a different facility. DISCLOSURE GAP: the Q2-26 10-Q (quarter ended 2026-06-30, filed 2026-08-04) does not mention Two Prime anywhere. No terminating statement has been located, so the facility's status after 2026-03-31 is unknown and is not asserted here.
