T1 Energy Inc., a Delaware corporation (“T1,” the “Company”, “we”, or “us”), is an energy solutions provider building an integrated U.S. supply chain for solar and batteries. We manufacture and sell photovoltaic (“PV”) solar modules in the United States for our U.S. customers.

The unaudited condensed consolidated interim financial statements have been prepared in conformity with the accounting principles generally accepted in the U.S. (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of U.S. Securities and Exchange Commission (“SEC”) Regulation S-X. Accordingly, these financial statements do not include all of the information required by U.S. GAAP for complete consolidated financial statements.

The unaudited condensed consolidated interim financial statements have been prepared on the same basis as the audited annual consolidated financial statements for the year ended December 31, 2024 and, in management’s opinion, include all adjustments, consisting of only normal recurring adjustments necessary for the fair statement of the Company’s condensed consolidated financial statements for the periods presented. The results of operations for the nine months ended September 30, 2025, are not necessarily indicative of the results to be expected for the full year ending December 31, 2025. The condensed consolidated balance sheet as of December 31, 2024, was derived from the audited consolidated financial statements as of December 31, 2024. However, these condensed consolidated interim financial statements do not contain all of the footnote disclosures required in annual consolidated financial statements. These unaudited condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on March 31, 2025, as amended and supplemented by Amendment No. 1 on Form 10-K/A filed with the SEC on April 30, 2025.

The condensed consolidated financial statements include the accounts of T1 and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated. Certain prior period balances and amounts have been reclassified to conform with the current period’s presentation.

The preparation of the condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Estimates and assumptions include, but are not limited to, estimates related to the fair value less costs to sell for assets held for sale, impairment of long-lived assets, derivative liabilities, the valuation of warrant liabilities, anti-dilution rights and share-based compensation. We base these estimates on historical experiences and on various other assumptions that we believe are reasonable under the circumstances, however, actual results may differ materially from these estimates.

We are subject to those risks common to our business and industry and also those risks common to early stage development companies. These risks include those disclosed in Part I, Item 1A, of our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on March 31, 2025, as amended and supplemented by Amendment No. 1 on Form 10-K/A filed with the SEC on April 30, 2025, as well as the risks described in Part II, Item 1A, “Risk Factors” in this Quarterly Report on Form 10-Q.

Our net sales and profits remain subject to variability based on, among other things, the availability and size of government subsidies and economic incentives. We expect the benefits made available to us by the Inflation Reduction Act of 2022 to favorably impact our liquidity and capital resources in future periods. For example, we expect to qualify for the advanced manufacturing production credit under Section 45X of the Internal Revenue Code, which provides certain specified benefits for solar modules and solar module components manufactured in the United States and sold to third parties. Such credit may be refundable by the Internal Revenue Service (“IRS”) or transferable to a third party and is available from 2023 to 2032, subject to phase down beginning in 2030. Accordingly, we expect the advanced manufacturing production credit will provide us with a significant source of funding throughout its remaining period. To date we have not received cash proceeds from the sale or direct pay from 45X tax credits. In August 2025, we agreed to defer any payments due under the Sales Agency Agreement between Trina Solar (US), Inc. and T1 G1 Dallas Solar Module LLC (f/k/a Trina Solar US Manufacturing Module 1 LLC) dated December 23, 2024 (the “Sales Agency Agreement”) until the earlier of August 15, 2026 and 30 days after we begin to monetize our accrued 45X tax credits.

Our future liquidity requirements depend on many forward-looking factors, including the timing and extent of the following: cash flows from operations, capital expenditures for construction of future facilities and purchase of related equipment, spending on other growth initiatives, including through joint ventures, and general economic conditions. In addition to those activities, our short-term liquidity will be utilized to fund the current portion of non-cancellable commitments, including leases and debt obligations. Our revenue recognized through the date of this Report is concentrated between certain customers and the loss of a contract with such customers could have a material adverse effect on the

Company including its liquidity. We monitor our working capital to ensure we have adequate liquidity, if we fail to collect trade receivables in a timely manner, offer extended payment terms to customers, or face other challenges in managing our working capital, we may be required to obtain temporary sources of funding or access capital markets.

These condensed consolidated financial statements have been prepared by management in accordance with U.S. GAAP and this basis assumes that we will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. As of the date of this Report, we believe that our cash and cash equivalents, cash flows from operating activities, and contracts with customers for the future sale of PV modules, are sufficient to support our planned operations for at least the next 12 months from the date of issuance of these financial statements. Therefore, our financial statements have been prepared on the basis that we will continue as a going concern.

During the nine months ended September 30, 2025, three customers accounted for 60%, 17%, and 15% of our total net sales. Two customers accounted for 85% and 15% of our aggregate accounts receivable trade, net as of September 30, 2025. The loss of a significant customer could have a material adverse effect on the Company.

Several of our key raw materials, components, and manufacturing equipment are sourced from highly specialized suppliers. The failure of any key supplier to perform could disrupt our supply chain and impair our ability to deliver solar modules to customers in the required quality, quantities, and pricing, which could adversely affect our results of operations.

Our solar modules are currently produced at a single facility in the United States. Shortages of essential components or equipment due to increased demand, supply interruptions, or limited logistics availability could adversely affect our ability to meet customer demand. Damage to, or disruption of, this facility could interrupt operations and negatively impact our ability to generate net sales.

The Inflation Reduction Act of 2022 (“IRA”) was signed into law in August 2022. Among other things, the IRA offers a tax credit, pursuant to Section 45X of the Internal Revenue Code (“IRC”), for solar modules and solar module components manufactured in the United States and sold to third parties. Such credit may be refundable by the IRS or transferable to a third party and is available from 2023 to 2032, subject to phase down beginning in 2030. We expect to qualify for a credit of approximately 7 cents per watt for each PV module we produce and sell to a third party. We recognize such credit as a reduction to cost of sales in the period the PV modules are sold to customers, and such credit is also reflected on our condensed consolidated balance sheets within government grants receivable, net.

Our operating leases primarily consist of our solar module facility in Wilmer, Texas and our G2_Austin solar cell manufacturing facility in Rockdale, Texas that we plan to develop. We also have short-term leases for which we elected to apply the short-term lease exemption to leases with a term of twelve months or less, and accordingly, have not recognized a right-of-use asset or lease liability. We have no other leases that are presented as continuing operations.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disclosure of disaggregated information about specific categories underlying certain income statement expense line items in the footnotes to the financial statements for both annual and interim periods. This ASU is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. This standard only modifies disclosure requirements; as such, we do not expect the adoption of this standard to result in a material impact on our condensed consolidated statements of operations and comprehensive loss, balance sheet or cash flows. We are currently evaluating the effect of the adoption of this standard on our disclosures.

In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (Topic 740). The ASU establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. The ASU is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. Upon adoption, the ASU can be applied prospectively or retrospectively. We are currently evaluating the effect of the adoption of this standard on our income tax disclosures related to our annual report for fiscal year 2025.

In July 2025, Accounting Standards Update 2025-05 (“ASU 2025-05”), Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, was issued to address challenges encountered when applying the guidance in Topic 326 to current accounts receivable and current contract assets arising from transactions accounted for under Topic 606. This standard introduces a practical expedient for entities that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. This standard is effective for annual periods, including interim reporting periods within annual reporting periods, beginning after December 15, 2025 with early adoption permitted. The Company is currently evaluating the impact of electing the practical expedient and the impact it may have on its consolidated financial statements and disclosures. We do not expect to incur material credit losses when assessing the collectability of receivable balances, and therefore, we do not expect the adoption of this standard to result in a material impact on our condensed consolidated statements of operations and comprehensive loss, balance sheet or cash flows.
