    Bill Papanastasiou's questions to Cipher Mining Inc (CIFR) leadership • Q4 2024

    Question

    Bill Papanastasiou asked how Cipher evaluates the terms of a potential HPC deal given the highly attractive revenue currently generated from bitcoin mining, and also requested an outlook for capital expenditures in 2025 and 2026.

    Answer

    CEO Tyler Page contrasted the two business models, explaining that while bitcoin mining offers high but cyclical returns, an HPC lease provides a stable, long-term revenue stream from a creditworthy tenant that is highly financeable with low-cost debt. For CapEx, he outlined approximately $200 million remaining for Black Pearl Phase 1. He noted that building out Phase 2 for bitcoin mining would cost an additional $260 million, a path they could pursue by raising capital if an HPC deal does not materialize.

    Question

    Bill Papanastasiou of Stifel asked for color on the capacity demands from hyperscalers, including whether they are looking at multiple sites, and questioned the changing difficulty of securing new greenfield power sites in Texas.

    Answer

    CEO Tyler Page explained that hyperscalers are showing an "outsized focus" on capacity available in 2025, typically screening for sites of at least 100-150 MW. He noted that securing sites is getting more challenging, which is why Cipher has moved earlier in the development cycle with its "3Ms" purchase options. Page highlighted a trend where grid operators are pushing hyperscalers to pair new load with new generation, which increases lead times and makes Cipher's existing interconnected sites more valuable.
