Summary

  • Fermi’s June 30 Form 10-Q identifies TensorWave as Project Matador’s first customer lease. The build-to-suit facility is described as supported by 222MW of total facility power only following the final delivery phase.
  • The filing estimates approximately US$6.5bn of contracted revenue over a 15-year initial term after final delivery. It also says the lease’s effectiveness depends on closing conditions, including board approvals and project-level financing; either party can terminate if they are not met.
  • Two additional TensorWave buildings could take aggregate capacity to 650MW only if an expansion option is exercised. The 650MW figure is an upper branch, not Phase 1 capacity.
  • Hillcore’s approximately 2.6GW generation framework has a different trigger: each block is activated by contracted tenant demand. Its PPA, tenant lease and physical generation therefore require separate receipts.

The signed lease is a commercial fact, not yet a commencement fact

Fermi Campus 1 LLC entered the TensorWave lease on August 9, according to the company’s June 30 Form 10-Q. That identifies the counterparty and the instrument more clearly than a customer pipeline claim. The landlord will develop, construct, deliver and operate a build-to-suit data-centre facility; TensorWave TEX1, LLC is the tenant, with its obligations guaranteed by TensorWave Inc. Fermi will guarantee the landlord obligations and has provided a completion guaranty for construction.

Those obligations make the document economically material. They also explain why a signed lease should not be narrated as a running service. The filing says its effectiveness is subject to customary closing conditions, specifically including board approvals and the landlord obtaining project-level financing. Closing was expected on or before September 30, 2026, subject to extension. Either party may terminate if those conditions are not met, and Fermi states that there is no assurance that they will be met or that the lease will commence.

That is not a minor footnote to erase because the headline contains a large number. It is the first clock. A lease can be signed and commercially specific while still awaiting the conditions that turn its parties from preparatory counterparties into an effective landlord and tenant. Until an update reports closing, an extension, a waiver or a termination, the prudent description is signed-but-conditional.

The 222MW belongs after final delivery

The second clock is physical and contractual delivery. The 10-Q says the facility will be supported by 222MW of total facility power following commencement of the final delivery phase. It does not say that TensorWave occupies 222MW now, that 222MW is energised to customer equipment, or that a 222MW load is already billed.

Fermi’s August investor presentation gives the time boundary more plainly: it calls 222MW “Phase 1 contracted capacity” and says phased delivery begins in the second half of 2027. That is useful specificity, but it remains a delivery schedule rather than an operations receipt. The passage from a project-financed construction obligation to tenant service has many possible gates: financing, engineering, power infrastructure, construction, commissioning, final delivery, tenant readiness and acceptance. The public record cited here does not collapse them into one completed event.

The lease is also a modified net lease. TensorWave is responsible for fixed and variable power charges and certain taxes as additional rent. That detail should prevent a second shortcut. A headline estimate of contracted revenue does not show which portions are base rent, which are pass-through economics, when each becomes billable or what costs and working capital sit alongside them. Capacity and contract value describe different denominators.

US$6.5bn is a term estimate, not cash, revenue or a construction budget

Fermi estimates approximately US$6.5bn in total contracted revenue over the initial 15-year term, excluding renewal terms and the expansion option. The number matters because it links a named tenant to an initial term and a stated Phase 1 power figure. Its wording also fixes its boundary. The term starts after final delivery; the estimate does not evidence a payment already received, revenue already recognised, a financed construction budget or a guarantee that no closing condition will interrupt commencement.

The third clock is therefore accounting and cash performance. A later filing can show whether the lease became effective, when final delivery occurred, what revenue was recognised, how pass-through charges were treated and whether the tenant’s load met the expected ramp. None of those receipts can be borrowed from the 15-year headline today.

Fermi’s July convertible-notes release makes the same separation necessary on the financing side. It describes US$431.25m aggregate principal amount of notes and approximately US$416.81m net proceeds before the disclosed capped-call use, with the remainder for general corporate purposes. The release says capital deployment at Project Matador is matched to commercial progress. It does not allocate a specific sum to the TensorWave building, a particular Hillcore block or every future power obligation. Balance-sheet runway is helpful, but it is not project-level financing evidence for the lease.

The 650MW ceiling is an election, not a present aggregate

The lease grants TensorWave an option for two additional buildings. If exercised, aggregate capacity could increase to 650MW. The company’s presentation presents the same distinction: 222MW is Phase 1, while roughly 650MW includes two expansion options.

An option has value precisely because it postpones an allocation decision. TensorWave can preserve access to a larger footprint while commercial demand, delivery performance, price and financing become clearer. But an option is not an election; an election is not a delivered building; and a delivered building is not a tenant load. Adding 222MW and 428MW as if both had the same contract and service status removes every decision still allocated to the tenant and every construction obligation still allocated to the landlord.

Hillcore is a separate demand-triggered supply ledger

The Hillcore framework should not be used to close that gap by rhetoric. Fermi’s investor presentation says Hillcore and its partners will finance, construct, own and operate approximately 2.6GW of combined-cycle generation under a long-term ground sublease. Fermi is to be anchor offtaker under a 20-year PPA, renewable in ten-year increments; the company says it commits no capital and issues no debt for the plant. It also says each block is triggered by contracted tenant demand and that Fermi’s purchase right after year ten is an option, not an obligation.

This describes a useful division of financing, ownership and optionality. It does not establish that every block has a tenant trigger, that any particular generating block is commissioned, that the TensorWave lease has commenced, or that every watt of the claimed generation has a matching delivered data-centre load. The lease ledger, the PPA ledger, the generation ledger and the tenant-service ledger can move at different speeds.

The first evidence to seek is correspondingly ordinary: a notice of lease closing or an extension; disclosed project-level financing; final delivery and service activation; separately reported rent and pass-through economics; an exercised expansion option; and, for Hillcore, a contracted-tenant trigger followed by construction and commissioning evidence for a named block. Those receipts will make the project more real. They should not be pre-booked by adding every future number to one present capacity line.
