The one-month extension of Fermi’s TensorWave lease is not a paperwork delay on a done deal. The 222 MW lease at Project Matador has never been effective: it was signed on 9 August subject to conditions, and on 22 September Fermi and TensorWave moved its closing date from 30 September to 31 October because the last big condition, a lease guaranty from an investment-grade counterparty, is still being negotiated. The new date lands one day after Fermi’s first annual shareholder meeting on 30 October, and ten days before a turbine-loan clause that starts to bite if the company has not signed 400 MW of lease or offtake agreements. Read together with the Texas Tech University System ground lease, Fermi now faces four hard dates in 62 days, and the lease that is supposed to carry it through all four is still conditional. For institutional holders, the real question is whether the whole calendar holds together, not whether TensorWave closes.Here is what no press release has put side by side. Fermi’s own Form 10-Q shows that the TensorWave lease clears one of its two big contract thresholds and misses the other. At 222 MW it satisfies the 200 MW first-tenant condition in the Texas Tech ground lease, which must be met before a notice to proceed that is due by 31 December. It falls short of the 400 MW that Fermi’s $500 million MUFG turbine warehouse facility uses to decide whether quarterly principal payments run at 5% or 10% of the balance. That test falls on 10 November, the facility’s nine-month anniversary. On the $444.9 million drawn at 30 June, the gap between the two rates is roughly $22 million a quarter. The 22 September announcement does not mention it.

A signed lease that has not started
The distinction that matters is between a lease that is signed and a lease that is effective. Fermi Campus 1 LLC, a Fermi subsidiary acting as landlord, signed the TensorWave lease with TensorWave TEX1, LLC on 9 August, and Fermi announced it the next day. Under the 10-Q, the lease only becomes effective once specified closing conditions have been met or waived. Either party can walk away if they are not.The 22 September release lists those conditions again: related work letters and guaranties, final operations schedules and a service-level agreement, Board approvals, and “project-level financing sufficient to fund construction of the leased premises.” One item on that list gets its own sentence. Fermi said it “continues to negotiate a guaranty of certain lease obligations with an investment-grade counterparty,” and that both sides pushed the date back to allow time to finish it. The release’s risk language gives the document a sharper name, the “rent guaranty”, which suggests the missing credit support sits behind TensorWave’s payment obligations rather than Fermi’s construction promises.That reading fits the 10-Q. The filing says TensorWave’s obligations are guaranteed by its parent, TensorWave Inc., and that Fermi itself has agreed to provide a guaranty of the landlord’s obligations plus a completion guaranty for construction. So the counterparty still being negotiated is a third layer of support. Lenders typically ask for that layer when a tenant’s own parent guarantee is not enough to fund a build. Fermi has not named the counterparty.The physical side of Project Matador keeps moving regardless. On 18 September Fermi reported that its first Siemens Energy SGT6-5000F gas turbines had reached the site near Amarillo, each weighing more than 480,000 pounds after a heavy-haul trip from the Port of Houston. That post gives no megawatt figure. Fermi’s second-quarter release does: three SGT6-5000F units “rated at up to 728 megawatts in simple-cycle mode,” alongside six smaller SGT-800 units capable of nearly 300 MW in phase one.Turbines on the ground and a tenant on paper are not revenue. That starts when finished halls are delivered to TensorWave, in phases from late 2027 into the first quarter of 2028, according to the 10-Q.Lee McIntire, Chief Executive Officer of Fermi, put the company’s position plainly in the 22 September announcement: “Our remaining work is to finalize the lease guaranty with our counterparty. Those discussions are active, constructive and progressing, and we look forward to closing and delivering Project Matador’s first data center for TensorWave.”
Who has spoken, and who has not
Fermi has been the only voice. The amendment was signed by both parties, yet as of the morning of 23 September TensorWave’s own news page carried no statement on the extension; its most recent Fermi item was August coverage of the original deal. The only TensorWave wording in the 22 September release is the standard boilerplate paragraph about its AMD Instinct GPU cloud and its investors, including Magnetar and AMD Ventures. TensorWave has not publicly addressed the guaranty, and Fermi’s wording, that it “continues to negotiate” the guaranty, puts the job of finding that counterparty on Fermi’s side of the table.The investment-grade counterparty is unnamed and silent by definition. So is MUFG Bank, the sole lender on the turbine facility, which has no reason to comment on a covenant that has not been tested yet. The Texas Tech University System, Fermi’s ground landlord, said nothing about the extension. Its chancellor, Brandon Creighton, welcomed the TensorWave deal in Fermi’s 10 August release. Its bargaining power sits in the lease terms, not in public statements.The loudest outside voice belongs to Toby Neugebauer, Fermi’s co-founder and former chief executive, who was removed as CEO in April. With his affiliated entities he holds about 22% of the shares outstanding, according to an exempt solicitation filed with the SEC on 11 September. That filing argued that 222 MW is less than 5% of the 4.8 GW of near-term power Fermi talks about. It also said that as of 10 September the company had not confirmed “the guaranteed agreement it previously said would support that lease.” He has filed a Rule 14a-8 proposal asking the Board to hire an independent investment bank to review “extraordinary transactions” before the 30 October meeting.Fermi’s Board, chaired by Marius Haas, set expectations on this exact point in August. The 10 August release did not describe the guarantor as something still to be found. It described a partner group already assembled, which is why the six weeks since then matter.”The committed partner ecosystem of developers, guarantors, and financing providers are all industry-leading companies, and TensorWave is exactly the kind of anchor customer our project was designed for,” Marius Haas, Chairman of the Board of Directors of Fermi Inc., said in the 10 August announcement.
Four dates, two thresholds, one conditional lease
Put the filed dates in order. None is new, and each comes from Fermi’s own filings or releases. What changed on 22 September is that the lease closing moved from the front of the queue into the middle of it.
| Date (2026) | Event | What it requires | Where the TensorWave lease stands | Source |
|---|---|---|---|---|
| 30 October | First annual meeting of stockholders | Shareholder votes; founder’s Rule 14a-8 proposal pending | Still unclosed on the day of the vote unless it closes early | 8-K, 31 Aug; PX14A6G, 11 Sep |
| 31 October | Extended TensorWave closing date | Guaranties, work letters, SLA, Board approvals, project financing | Conditions outstanding; either party may terminate if unmet | Release, 22 Sep; 10-Q |
| 10 November | Nine-month anniversary of MUFG turbine facility | Signed lease or offtake of at least 400 MW for phase one | 222 MW, or 178 MW short on its own | 10-Q, Note 5 |
| 31 December | Texas Tech notice-to-proceed deadline | First tenant of at least 200 MW plus phase-one financing | Clears the 200 MW bar by 22 MW if it becomes effective | 10-Q, Note 6 and risk factors |
The MUFG line is where money is at stake. The facility closed on 10 February 2026, carries interest at SOFR plus 4.0% and matures on 10 August 2027. From the nine-month mark, quarterly principal is 10% of the outstanding balance, cut to 5% if a qualifying 400 MW deal has been signed. If none has, the lender’s agent “may begin marketing the equipment to potential buyers, but may not sell or foreclose absent an event of default.” On the $444.9 million balance reported at 30 June, 10% works out to about $44.5 million a quarter against $22.2 million at the lower rate.Set that against the balance sheet. Fermi reported $91.7 million of cash and restricted cash at 30 June, then took in $416.8 million of net proceeds from the July convertible notes, before the cost of related hedges. The 10-Q still carries going-concern language. Management says its plans “alleviate the substantial doubt,” but it states that the additional customer and project-level arrangements it is pursuing were “not relied upon” in reaching that conclusion. The TensorWave closing, in other words, is upside to the liquidity case Fermi has filed, not part of it.The stock has priced some of this in. FRMI closed at $5.88 on 10 August, the day the lease was announced, then rallied to $7.12 on 11 August, when Fermi also unveiled its Hillcore alliance, and $7.60 on 12 August, according to Nasdaq data. It closed at $5.14 on 22 September, up 1.6% on the day of the extension, and its 52-week range runs from $4.47 to $36.99. The notes convert at about $9.52, so the shares trade at roughly 54% of the conversion price. Retail posts on X focused on timing, with two accounts arguing that an extension announced eight days early meant the parties already knew they would miss 30 September. That is sentiment, not evidence.FinanceFeeds has looked at Fermi’s pre-revenue financials and the $6.5 billion anchor tenant before, and at the bull and bear price cases for FRMI. The dated sequence above adds the dependency chain between the lease and Fermi’s other contracts.
Where the financing and governance pressure meets
Every date in the table depends on project finance, and every project-finance lender will want the same thing: a creditworthy rent stream. That is why the lease guaranty is doing so much work. Under the Texas Tech lease, the notice to proceed needs both a 200 MW first tenant and financing for the first phase. The TensorWave lease itself lists project-level financing as a closing condition. So Fermi cannot close the lease without financing, and construction lenders are unlikely to fund a 15-year data centre lease without an investment-grade guarantor behind the rent. The guaranty unlocks the other steps, and it is the one piece Fermi does not control.Scale sets the stakes. The 10-Q puts total capital needs across all phases of Project Matador at roughly $70 billion to $90 billion, and says phase one “will require capital in addition to the sources currently available.” Fermi has also signed a framework with Hillcore Energy Capital for about 2.6 GW of generation that Hillcore would finance and own, with Fermi as the offtaker under a 20-year power purchase agreement. That arrangement keeps generation capital off Fermi’s balance sheet. The data halls TensorWave will rent still need their own debt.Governance runs alongside the financing. A Board whose chairman described committed guarantors in August faces shareholders on 30 October with that guarantor still unsigned. Neugebauer’s investment-bank proposal, if it reaches the ballot, gives the meeting a clear referendum question. Neugebauer’s filing also points to a 2.5% ownership cap in Fermi’s charter, which he says limits how large a stake any single institution can hold. The 10-Q lists the dispute with him, including litigation, among its material risks and says it has diverted Board and management attention.There is also a regulatory side outside the company. Federal legislators are pushing data centres to pay for their own grid impact, a debate FinanceFeeds covered after the House passed the Ratepayer Protection Act 417-3. Behind-the-meter campuses such as Project Matador are pitched as the answer to that pressure. Equity markets are rewarding power deals that come with contracted counterparties, as Vistra’s 207 MW Odessa agreement showed. Fermi’s pitch holds up only if a signed tenant turns into a funded one.Neugebauer’s filing sets out the governance case against the current Board in its own words. “The Board and management team have fallen significantly short on the promises they made to the institutional and retail investor communities post my termination, during the proxy contest, and as part of the convertible note offering,” Toby Neugebauer, co-founder and former Chief Executive Officer of Fermi, said in the 11 September statement filed with the SEC.
What happens next
First, a closing and a financing announcement will most likely arrive together, or not at all. Project-level financing is a closing condition, and lenders will want the rent guaranty in place before they commit. That means the guaranty signature, the construction loan and the lease closing are likely to be announced as one package. If Fermi announces a closing without naming its lender, investors should check the 8-K to see whether the financing condition was met or waived.Second, another extension is possible, but only as far as 31 December. The amendment shows both parties are willing to move the date. The Texas Tech notice-to-proceed deadline limits how far it can move. The notice depends on a 200 MW first tenant plus phase-one financing, and TensorWave is Fermi’s only disclosed tenant. A second extension into November would still leave room. One that runs past mid-December would put the ground lease itself at risk, and the extension would then become a much bigger disclosure.Third, 10 November will probably appear in the third-quarter 10-Q whatever happens on 31 October. Even a closed TensorWave lease leaves Fermi 178 MW short of the MUFG threshold unless a second tenant signs or TensorWave exercises part of its expansion option toward the 650 MW total the 10-Q describes. Watch for a waiver, an amendment or disclosure of the higher 10% amortisation rate. On the second-quarter timetable, that filing would land in mid-November, after both October dates have passed.The cause and effect are straightforward. The guaranty drives the financing, the financing drives the closing, the closing drives the Texas Tech notice, and none of it on its own fixes the 400 MW test.
Frequently asked questions
Has the Fermi TensorWave lease been cancelled?
No. On 22 September Fermi announced that Fermi Campus 1 LLC and TensorWave TEX1, LLC had signed a first amendment that moves the closing date from 30 September to 31 October 2026. Fermi says all other terms, including the 222 MW size and the roughly $6.5 billion of expected revenue over 15 years, are unchanged. The lease is still not effective until its closing conditions are met or waived.
What is the lease guaranty Fermi is negotiating?
Fermi says it is negotiating a guaranty of certain lease obligations with an investment-grade counterparty that it has not named. The release’s risk language calls it a rent guaranty. TensorWave’s parent already guarantees the tenant’s obligations, so this appears to be extra credit support that construction lenders will require before financing the build.
Why does 10 November matter for Fermi?
That is the nine-month anniversary of Fermi’s $500 million MUFG turbine warehouse facility. From that date, quarterly principal is 10% of the outstanding balance unless Fermi has signed a lease or offtake deal of at least 400 MW for phase one, in which case it is 5%. Without such a deal, the lender may also start marketing the turbines to buyers.
Does the TensorWave lease satisfy the Texas Tech ground lease?
On size, yes. The Texas Tech University System lease requires a first tenant of at least 200 MW before a notice to proceed, and TensorWave’s lease covers 222 MW. That notice must be issued by 31 December 2026, and it also depends on phase-one financing, so the lease has to become effective and funded, not just signed.
When is Fermi’s annual meeting?
Fermi’s first annual meeting of stockholders is scheduled for 30 October 2026, with a record date of 31 August, according to its 31 August Form 8-K. That is one day before the extended TensorWave closing date. The company’s co-founder, who holds about 22% of the shares, has filed a proposal seeking an independent strategic review.This article is analysis based on public company filings and releases and is not investment advice.
