Key points
- T1 Energy raised the cost estimate for phase one of its Austin solar cell fab from $425 million to $510 million and pushed first cell production from late 2026 to the first quarter of 2027. It blamed labor and materials costs in the Texas data center construction market.
- Eleven weeks ago the company said that same project was on schedule with its timeline unchanged.
- A second filing the same morning disclosed that T1 paid $135 million for the solar patents it had been licensing. Trina Solar owned those patents until December 29, 2025.
- The first $60 million is due within three business days, and T1 intends to pay it in stock priced at a 15% discount to a five-day average that includes this week's selling.
- Second quarter sales of $245 million to $255 million would be a company record, but adjusted EBITDA swung to about negative $13 million from a positive $9.1 million in the first quarter.
T1 Energy (TE) filed two current reports with the SEC six minutes apart before the open Tuesday. The one getting the headlines is the second quarter pre-announcement. The more interesting number is buried in its business update.
T1 is building a solar cell factory in Austin called G2_Austin. Phase one was budgeted at $425 million. It is now $510 million. The first cells were supposed to come off the line before the end of this year. They are now expected in the first quarter of 2027.
The company's explanation, in its own words, is "labor and materials costs associated with tightness in the Texas data center construction market."
That is the first time we have seen a public company put a dollar figure and a calendar quarter on something Texas builders have complained about all year.
Read the $510 million carefully
$510 million is exactly 20% above $425 million, and T1 describes the new figure as one "which represents a 20% contingency." Read that as the old estimate plus a cushion rather than $85 million of invoices already run up. The distinction matters and most coverage will skip it.
The delay carries no such cushion. Steel work at the site has reached 80% completion, which the company reported Tuesday as progress, and first cells still moved a quarter to the right.
Eleven weeks ago this project was on schedule
On May 12, T1's first quarter release opened a bullet with the words "Construction proceeding on schedule at G2_Austin, timeline for completion unchanged." Seventy-seven days later the budget carries a fifth more contingency and first production sits a quarter further out.
Nothing about the fab itself changed. What changed is the price of getting people and materials to a construction site in Central Texas.
What Texas builders have been saying since April
The Texas Tribune reported in April that data center projects pay electricians about $35 an hour plus overtime and per diem, while residential contractors manage $20, maybe $25 on a good day. Gene Lantrip, president of the Texas Association of Builders, said his construction timelines now run two months longer than they used to.
The state has a pool of about 71,000 electricians, more than 300 data centers already operating, and about 100 more planned. Electrical work runs a large share of a data center construction budget, which is why those projects can outbid almost anyone else for the same crews.
Homebuilders losing two months to that competition is a story about housing. A solar fab losing a quarter and adding a 20% contingency is the same story showing up in an SEC filing, with a number attached.
T1 just bought its way into that same boom
T1 closed its acquisition of KORE Power in July, a deal announced June 3 at about $32 million in enterprise value. The stated reason was to get T1 into battery storage and, specifically, AI data center infrastructure.
So the same buildout bidding away T1's contractors in Austin is the customer base T1 just paid to reach. Both things are true at once, and neither cancels the other. It does mean the AI power trade cuts in two directions for a company that has to physically build something before it can sell into it. We laid out the group-wide version of that trade in our look at solar and storage as the fast lane for AI power.
$135 million for patents it was already renting
The second filing is a separate transaction and, in dollar terms, the bigger one.
T1 bought the TOPCon solar cell and module patents it had been licensing, outright, from Singapore-based Evervolt Green Energy Holding Pte Ltd. Total consideration is $135 million. The existing license agreements terminated on closing.
Those patents have a history. Trina Solar owned them until December 29, 2025, when it sold them to Evervolt as part of a series of transactions T1 ran to avoid being classified a prohibited foreign entity under the One Big Beautiful Bill Act. That classification would have cost T1 its Section 45X manufacturing tax credits, which is the line item its margins run on. At the time, T1 said it had done diligence and believed Evervolt was not a foreign entity of concern.
Short seller Fuzzy Panda Research has been pressing on T1's China supply chain ties since spring, and the license was one of the threads. Owning the patents rather than renting them from a Singapore holding company that got them from Trina six months earlier removes that thread. Chairman and CEO Dan Barcelo framed it commercially, saying the deal eliminates future royalty payments and that the IP "will be accretive to T1 economically in addition to yielding significant commercial and strategic benefits."
He is not wrong about the royalties. He also did not mention the compliance angle, and the filing's list of seller representations includes one confirming Evervolt's status as a non-specified foreign entity under the tax code. Draw your own conclusion about which motivation came first.
How T1 plans to pay for it
This is where existing shareholders should pay attention.
T1 already paid $2 million in cash for the option. The remaining $133 million comes in four tranches: $60 million within three business days of Tuesday's close, $25 million on September 30, $30 million on October 15 and $18 million on October 30.
Each tranche is payable in cash, in stock, or a mix, at T1's election. The company said it currently intends to pay the first $60 million in stock.
Stock issued this way is priced at a 15% discount to the volume weighted average price over five trading days, in a window ending two business days before the shares go out. With the first payment due within three business days, that window covers this week, including Tuesday's drop.
Run the math. T1 had 279.3 million shares outstanding as of May 8. If the five-day average lands near $4.90, the 15% discount prices the shares near $4.17, and $60 million buys about 14 million of them. That is roughly 5% dilution for the first tranche alone. Paying the entire $133 million in stock at that level would be closer to 32 million shares, or 11%. The agreement caps total share consideration at 19.9% of shares outstanding, with any excess paid in cash.
Cash is the constraint. T1 had $156.4 million in cash, cash equivalents and restricted cash on June 30, of which only $79.1 million was unrestricted. That is up from $46.4 million unrestricted at the end of March, helped by monetizing the last of its 2025 Section 45X credits for $39.1 million at 93 cents on the dollar. It does not cover $133 million in cash payments and a $510 million fab at the same time, and T1 still has no announced financing for phase one. The company says it "continues to target a comprehensive financing solution, which includes a significant debt component, in an amount sufficient to fund the remaining estimated capital expenditure required for G2_Austin Phase 1." Back in May it was targeting that package "in the second quarter." The second quarter has ended.
T1 also added a new line to its own risk factors on Tuesday, listing "T1's ability to satisfy each installment of consideration for its acquisition of intellectual property from Evervolt as it becomes due." Companies write those lists to protect themselves, so read it as disclosure rather than distress. It is still the company telling you which payment it is thinking about.
The quarter itself
The headline numbers look good until you get to the profit line.
| Measure | Q2 2025 | Q1 2026 | Q2 2026 (preliminary) |
|---|---|---|---|
| Net sales | $132.8M | $177.6M | $245M to $255M |
| Net income (loss), continuing ops | n/a | $3.9M | ($34M) to ($37M) |
| Adjusted EBITDA | n/a | $9.1M | ($14.5M) to ($11.5M) |
| Unrestricted cash | n/a | $46.4M | $79.1M |
Sales of $245 million to $255 million on 835 MW of modules would be a company record, ahead of the $210.5 million T1 booked in the third quarter of 2025, and up more than 80% from the same quarter last year.
Underneath that, the first quarter's record profit is gone. T1 reported net income from continuing operations of $3.9 million and adjusted EBITDA of $9.1 million in the first quarter, both records. The second quarter turns those into a $34 million to $37 million loss from continuing operations and adjusted EBITDA of about negative $13 million.
One detail most write-ups will skip. That negative adjusted EBITDA figure excludes about $24.4 million of tariff refunds T1 expects under the International Emergency Economic Powers Act. Companies usually strip out charges to make a non-GAAP number look better. T1 stripped out a benefit, which makes it look worse. Include the refunds and adjusted EBITDA is positive. The conservative version is the one the company chose to headline.
Note also that these are preliminary, unaudited figures that T1's auditor has not reviewed. Companies do not normally pre-announce a quarter for fun. Getting current financial information out before issuing stock to a seller is a familiar reason to do it.
The good news, which is real
T1 now expects 2026 production at G1_Dallas to land at the high end of its 3.1 to 4.2 GW range, and expects third and fourth quarter output to run above the second quarter. It credits progress qualifying international cell vendors to supply the Dallas plant. It also opened early talks on selling its 2026 vintage 45X credits.
Higher volumes at thinner margins is what happens when a manufacturer buys cells on the open market while it waits for its own cell fab. The whole point of G2_Austin is to stop buying them. The delay pushes that fix out a quarter.
Where the stock stands
TE closed at $4.90 on Monday, down about 59% from its June 2 close of $12.04 and still well above its August 1, 2025 low of $1.15.
Tuesday's pre-market told the story of a market reading two filings at once. The stock printed as high as $5.34 and as low as $4.15, a 29% range before the opening bell, and was near $4.60 at 8 a.m. ET. Whichever way the regular session settles, the spread between those two prints is the honest summary: a record sales quarter and a cheaper path to owning its core technology on one side, a delayed fab, a swing to an operating loss and imminent dilution on the other.
Solar has been broadly weak since early June. We covered the group's drawdown on July 24, when TE was already the worst performer in the sector, and the brief rally on Chinese inverter ban headlines before that. For the demand side of the AI buildout that is now raising T1's construction bills, see our piece on the $725 billion big tech data center capex plan.
What to watch
- Whether T1 issues the first $60 million in stock and at what price. A registration statement or prospectus supplement covering resale is due within five business days of each stock payment, which will show the exact share count.
- The financing package for G2_Austin phase one. T1 has been targeting it since the first quarter and it has not landed. $510 million is the number it now has to cover.
- Full second quarter results, which will confirm or revise these preliminary figures.
- The Section 232 polysilicon decision expected in early August, which affects the whole group.
- Whether other Texas manufacturers start putting the same line in their filings. If data center construction costs are moving a solar fab budget by a fifth, T1 will not be the last company to say so.
