Cipher Mining Inc. (CIFR) | The Buildout — AI Infrastructure
The Verdict
Cipher Digital is a vertically integrated developer and operator of industrial-scale data centers. It originates land, power, and interconnection, then designs, builds, and operates turnkey campuses for hyperscalers and HPC tenants under long-term leases. That makes it a supplier of the power-dense physical capacity AI compute requires.

What We Like
- Three signed HPC campus leases anchor approximately $11.4B of contracted revenue across 10-15 year base lease terms (Q1 2026 call).
- Contracted NOI guided to about $793M average annualized from October 2026 through September 2036 (Q2 2026 call).
- Black Pearl first capacity delivered in August 2026, two months ahead of schedule, with rent commenced.
- Three project-level bond financings priced tighter sequentially: Barber Lake 7.125%, Black Pearl 6.125%, Stingray 6.000%.
- Portfolio about 5.3 GW across 11 sites; 477 MW potentially available in 2027 outside the ERCOT batch process.
What We’re Watching
- ERCOT Batch Zero timing slipped from June 2026 after the Texas Governor's letter; no firm new date was given.
- Stingray timeline wording shifted from Q4 2026 energization to first-half 2027 delivery, not explicitly reconciled.
- Revenue continues to fall: $59.7M Q4 2025 to $35M Q1 2026 to $25M Q2 2026 while HPC rent ramps.
- Tenant concentration is high: three HPC tenants anchor the contracted book; one is undisclosed.
The contracted near-term thesis is strengthening: the first HPC rent began early, and the third project bond priced at the lowest coupon yet. The farther-out thesis is unresolved: the 2028+ pipeline depends on an ERCOT decision that just slipped. The key open question is whether management can convert its 477 MW of near-term uncontracted capacity into signed leases before the mining bridge fully winds down.
Earnings
Q2 2026 revenue was $25 million, down from $35 million in Q1, reflecting the planned decommissioning of bitcoin mining at Black Pearl. Net loss widened to $268 million, driven largely by a $150.5 million noncash warrant remeasurement loss. Unrestricted cash rose $204 million to $832 million.
| Metric | Q1 FY2026 | Q4 FY2025 | Q1 FY2025 | YoY |
|---|---|---|---|---|
| Revenue | $35M | $60M | $49M | −29.0% |
| Gross margin | -105.9% | 1.2% | 40.4% | -14630bps |
| EBITDA | −$29M | −$177M | $6M | −608.8% |
| EPS | $-0.28 | $-1.92 | $-0.11 | +160.8% |
I'm proud to announce the early delivery of data center capacity at Black Pearl, 2 months ahead of schedule. At the request of our tenant, we executed an amendment to the lease that accelerated the development time line of initial capacity. I'm pleased to report that we delivered that capacity and rent has commenced at the site.— Tyler Page, CEO, August 4, 2026
Management tone: Management's tone shifted from Q4 2025 transition framing, to Q1 2026 execution framing ("2026 is the year of execution"), to Q2 2026 flywheel framing ("each step forward in the progress of our flywheel is now reinforcing the next"). On the Q2 call management was candid about the ERCOT delay and unusually unhedged about demand.
Management Guidance
Management does not give traditional revenue or EPS guidance. Its formal forward figures are contracted capacity, revenue, and NOI: approximately $11.4B of contracted revenue across 10-15 year base lease terms; approximately $793M average annualized NOI from October 2026 through September 2036; and a portfolio of roughly 5.3 GW across 11 sites. The company also said it expects no additional equity based on the current forecast, with the CFO's caveat that pipeline or lease materialization could create a future need.
Trajectory
Reported revenue is declining by design: $59.7M in Q4 2025, $35M in Q1 2026, and $25M in Q2 2026, as bitcoin mining at Black Pearl was decommissioned. The forward picture shifts to contracted HPC NOI: Black Pearl rent commenced in August 2026 and Barber Lake rent is expected in October 2026, while contracted HPC NOI guidance rose from about $669M at Q4 2025 to about $793M at Q2 2026. Gross, operating, and EBITDA margins are compressing through the transition, and Q1 2026 adjusted EBITDA was negative at -$48.2M.
The Model
The model projects FY+1 revenue of $249M and EBITDA of $43M (17.4% margin), rising to FY+2 revenue of $770M and EBITDA of $601M (78.0% margin). The near-term projection is anchored by early HPC rent at Black Pearl and Barber Lake; FY+2 reflects the step-up as the contracted HPC NOI stream ramps.

What Could Go Right — and Wrong
- Black Pearl and Barber Lake deliver on schedule and convert leases into the contracted ~$793M average annualized NOI stream.
- The 477 MW outside the ERCOT batch process (Odessa, Reveille, Ulysses) is leased at improving terms.
- Colchis, Mikeska, and McLennan are expected in ERCOT Batch Zero and would move the 2028-2029 pipeline forward.
- Odessa PPA renegotiation converts the 207 MW legacy mining site to HPC by late calendar 2027.
- Behind-the-meter generation or compute ownership becomes a committed project and expands the model beyond colocation.
- Stingray or Barber Lake timing slips further, delaying rent commencement and contracted NOI conversion.
- The ERCOT batch-process audit reorders or delays the 2028+ pipeline beyond management's expected 2028-2029 window.
- Labor and equipment inflation raises build budgets and cost per megawatt beyond contracted caps.
- A tenant concentration event at one of the three HPC tenants reduces the contracted NOI base.
- Financing markets tighten enough to force an equity raise the company currently says it does not need.
Looking Ahead
Over the next 12 months, the story shifts from signing leases to delivering and converting them into rent. Barber Lake Phase 1 is due for September 2026 delivery with October rent; Black Pearl's remaining Phase 1 and Phase 2 capacity continues delivery; Stingray is expected in first-half 2027. The biggest external gate is the now-undated ERCOT Batch Zero decision, which gates the 2028+ pipeline.
- Q3 2026Stingray foundation and steel start — Tests third leased campus staying on schedule; earthwork and underground electrical underway.
- September 2026Barber Lake Phase 1 delivery — Tests second contracted HPC delivery; tenant has already begun beneficial use.
- October 2026Barber Lake rent commencement — Tests conversion of the second lease into contracted NOI.
- First half 2027Stingray delivery — Tests full first wave of the contracted portfolio; financing complete.
- Q3 2027Reveille energization target — Tests first uncontracted near-term site if leased; advanced lease discussions.
- Q4 2027Ulysses energization target — Tests PJM-approved site reaching energization; advanced lease discussions.

The Company
Cipher Digital develops and operates industrial-scale data centers built for power-dense computing. It has intentionally evolved from a pure-play bitcoin miner into a vertically integrated data center development and operations platform; the core product is contracted, turnkey hyperscale capacity under 10-15 year leases. That capacity sits at the physical layer of the AI compute buildout.
Cipher controls the full value chain, including land and power origination, interconnection, site development, data center design and construction, and ongoing operations, rather than outsourcing development. It reports two segments, HPC Data Centers and Bitcoin Mining, but the mining segment is now a bridge at the 207 MW Odessa site, being wound down or converted while the company builds out roughly 5.3 GW across 11 sites.
Business Segments
Competitive Landscape
Cipher's own 10-K names CoreWeave, Digital Realty, Equinix, Vantage Data Centers, and Aligned Data Centers as HPC services competitors, and Hut 8, IREN, TeraWulf, Core Scientific, and Applied Digital as bitcoin-mining competitors that expanded into HPC. The company's positioning rests on scarce power and interconnection rights, in-house procurement, and delivered execution.

Supply Chain
Cipher sits between utilities, grid operators, and equipment providers on one side and hyperscale tenants on the other, converting power and interconnection rights into leased data center capacity. Its named EPC partner is Quanta Services; Odessa's power supplier is Luminant/Vistra.
