T1 Energy, the Texas solar module maker, ended September with $59.5 million of cash and cash equivalents, down 67% from $182.5 million at the end of 2025, by our arithmetic from its third-quarter release of 12 November. The company said closing a financing solution for its G2_Austin cell fab remains its top priority.
Third-quarter total net sales were $196.6 million, against $210.5 million a year earlier, and the net loss attributable to common stockholders was $41.6 million, or $(0.14) per share. Over nine months, cash used in operations plus spending on property and equipment came to $425.9 million, by our arithmetic.
Business Pill · Free Cash Flow
An evergreen Business Engineer explainer on free cash flow: profit on paper versus cash in the bank. It teaches the general idea only and does not discuss T1 Energy.
The key insight: As we read the release, T1 Energy is funding a 2027 ramp with its balance sheet before its Austin cell fab is financed: cash fell 67% to $59.5 million in nine months while inventory rose 2.9 times and convertible notes 3.2 times, by our arithmetic.
Inventory rose to $335.4 million at 30 September from $116.0 million at the end of 2025, 2.9 times as much, by our arithmetic. T1 said it produced 1,056MW of modules at G1_Dallas in the quarter and built 326MW of module inventory to facilitate 2027 deliveries under recently signed offtake contracts.
Nine-month cash used in operating activities was $175.8 million and purchases of property and equipment and intangible assets were $250.1 million, the release’s cash flow statement shows. Financing brought in $300.3 million, including $341.6 million of convertible notes net of underwriting fees.
Gross margin was 8.5% and Adjusted EBITDA was ($16.4) million. SG&A of $71.2 million was 4.3 times gross profit of $16.7 million, by our arithmetic; T1 attributed SG&A to growth in technical and operational headcount and higher financing, transaction and legal expenses.
T1 Energy balance sheet, $ million, 31 December 2025 to 30 September 2026, from its third-quarter release: cash and cash equivalents fell from $182.5 million to $59.5 million, inventory rose from $116.0 million to $335.4 million and convertible notes rose from $153.0 million to $495.1 million. Percentages and multiples are our arithmetic.
The Austin Fab and the Financing
T1 said it is negotiating a G2_Austin debt financing with certain institutional investors under exclusivity, and that any financing may include or require the issuance of additional equity or equity-linked securities. It said there can be no assurance a financing will be completed on a timely basis, on acceptable terms, or at all.
T1 said it intends to “temporarily match the pace of capital spending at G2_Austin with the expected timeline to close a G2_Austin financing solution”. On 30 October its offtake release said the first 2.1GW phase of the Rockdale, Texas cell fab was expected to produce cells in Q1 2027.
On 30 September T1 placed an additional $50 million of 4.75% convertible notes due 2031, which it called a bridge to a G2_Austin financing. Convertible notes on the balance sheet rose to $495.1 million from $153.0 million at the end of 2025.
Contracts, Customers and the Data-Centre Asset
The release says T1 now has more than 3.5GW of its 2027 manufacturing capacity under contract. Its 30 October release said more than 4GW; both figures are lower bounds, and we covered the 30 October deals at the time. T1 set preliminary 2027 production guidance of 5.3GW and narrowed 2026 G1_Dallas production guidance to 4.0-4.2GW.
Related-party sales were $189.9 million of the quarter’s $196.6 million, about 97% of the total, by our arithmetic from the income statement. T1 also said it has generated $155.3 million of Section 45X production tax credits through the third quarter and is in conversations to monetise them.
T1 said it signed a non-binding letter of intent to explore repurposing its Nordic Giga Arctic site as a data centre, where Norway’s grid operator Statnett has allocated 50MW. Under the LOI the partner would finance capital spending and find a tenant or compute offtaker.
The Structural Read
As we read the cash flow statement, $425.9 million went into operations and capital spending over nine months, by our arithmetic, and convertible notes of $341.6 million net were the main source of new money.
As we read the two releases, demand is not the stated constraint: T1 says it may sell out G1_Dallas for 2027, yet it will pace G2_Austin spending to the timing of a financing it says may require additional equity or equity-linked securities.
Dan Barcelo, Chief Executive Officer and Chairman of T1 Energy, third-quarter 2026 release, 12 November 2026
“Following the Commerce Department’s Section 232 proclamation, pricing and demand for G1_Dallas modules has improved meaningfully”
Three Implications
FOR SHAREHOLDERS T1 said any G2_Austin financing may include or require the issuance of additional equity or equity-linked securities.
FOR CUSTOMERS T1 said it now has more than 3.5GW of its 2027 manufacturing capacity under contract and set preliminary 2027 production guidance of 5.3GW.
FOR AI INFRASTRUCTURE T1 said it signed a non-binding LOI to explore repurposing its Nordic Giga Arctic site as a data centre, with a 50MW grid allocation from Statnett.
The framework says: “The structural bottleneck isn’t computing, it’s electrons.”
As we read it, T1’s quarter shows the supply side of those electrons is capital-bound too: a domestic solar maker with contracted demand is pacing its cell fab to a financing. The framework predates these results and does not discuss T1 Energy.
T1 Energy’s third-quarter 2026 total net sales of $196.6 million, split between related-party net sales of $189.9 million and other net sales of $6.7 million, per its statements of operations. The 97% share is our arithmetic.
What Is Not Established
The release does not name the related party, the G2_Austin lenders or the Nordic partner, and gives no new date for first cells from Austin. T1’s quarterly report on Form 10-Q was not on EDGAR when we checked at 11:50 UTC on 12 November, so we have not read its risk factors or notes.
The fall from more than 4GW to more than 3.5GW compares two lower bounds from T1’s own releases; the company did not explain the difference in the documents we read. We did not contact T1 for this piece.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
T1 Energy ended the quarter with $59.5 million of cash after $425.9 million went into operations and capital spending over nine months, by our arithmetic. It says closing a G2_Austin financing is its top priority and it will pace spending at the cell fab to that timeline.
A note on sourcing. All figures come from T1 Energy’s third-quarter 2026 release of 12 November, read in full including its financial tables, and its 30 October offtake release. T1’s Form 10-Q had not been filed when we wrote. Percentages, multiples and the nine-month total are our arithmetic. T1 was not contacted for this piece.
