CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q, including the information and documents incorporated by reference herein, contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements other than statements of historical or current facts contained or incorporated by reference in this Quarterly Report on Form 10-Q may be forward-looking statements. Statements regarding our future results and timing of operations, expected performance and financial position, business strategy and plans and objectives of management for future operations, including, among others, statements regarding liquidity, growth and profitability strategies and factors and trends affecting our business are forward-looking statements. Forward-looking statements can be identified in some cases by the use of words such as “believe,” “can,” “could,” “potential,” “plan,” “predict,” “goals,” “seek,” “should,” “may,” “may have,” “would,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” or the negative of these words, other similar expressions or by discussions of strategy, plans or intentions and are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words.

The forward-looking statements contained or incorporated by reference in this Quarterly Report on Form 10-Q are only predictions. We base these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. Forward-looking statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements, or industry results, to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. We believe that these risks, uncertainties and other important factors include, without limitation, the risks set forth in Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2025 filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 31, 2026, as amended and supplemented by Amendment No. 1 on Form 10-K/A filed with the SEC on April 30, 2026, and in our other filings with the SEC, including risks related to: (1) our ability to (i) construct and equip manufacturing facilities in a timely and cost-effective manner; (ii) target and retain customers and suppliers; (iii) attract and retain key employees and qualified personnel; (iv) protect our intellectual property; (v) comply with legal and environmental regulations; (vi) compete in international markets in light of export and import controls; (vii) incur substantially more debt; (viii) remediate the material weakness in our internal control over financial reporting or otherwise maintain effective internal control over financial reporting; (ix) qualify for the advanced manufacturing production credit under Section 45X of the Internal Revenue Code of 1986, as amended; and (x) our exposure to warranty claims; (2) our ability to secure comprehensive financing solution to fund the remaining capital expenditure for Phase 1 of G2_Austin (as defined herein) on favorable terms, or at all, and the timing of such financing; (3) the concentration of our operations in Texas and our dependence on a limited number of suppliers; (4) changes adversely affecting the flow of components and materials from international vendors, the costs of raw materials, components, equipment, and machinery; (5) general economic and geopolitical conditions, (6) changes in applicable laws or regulations, including environmental, export control and tax laws and incentives and renewable energy targets, as well as international trade policies, including tariffs, on our products and our competitive position (including T1’s ability to obtain tariff refunds); (7) the outcome of any legal proceedings relating to our products and services, including intellectual property or product liability claims, commercial or contractual disputes, warranty claims, and other proceedings; and (8) the capital-intensive nature of our business and our ability to raise additional capital on attractive terms or service our debt.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this Quarterly Report on Form 10-Q, or the documents incorporated by reference herein, and while we believe such information provides a reasonable basis for these statements, and our management is responsible for the accuracy of such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you are cautioned not to unduly rely upon these statements.

You should read this Quarterly Report on Form 10-Q, and the documents incorporated by reference herein, with the understanding that our actual future results, levels of activity, performance and achievements may be materially different from what we expect. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by these cautionary statements.

These forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q. Except as required by applicable law, we do not assume any obligation to update any forward-looking statement, whether as a result of any new information, future events or otherwise.
