These forward - looking statements are based on management’s current expectations. These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause actual future events, results, or achievements to be materially different from T1’s expectations and projections expressed or implied by the forward - looking statements. Important factors include, but are not limited to, those discussed under the caption “Risk Factors” in (i) T1's Annual Report on Form 10 - K for the year ended December 31, 2024, filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 31, 2025, and (ii) T1’s Quarterly Report on Form 10 - Q for the quarterly period ended September 30, 2025, filed with the SEC on November 14, 2025, including risks related to: (1) T1's 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 its 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 T1's internal control over financial reporting that T1 have previously identified and a material weakness that T1 identified for the fiscal year ended December 31, 2025, or otherwise maintain effective internal control over financial reporting, (viii) qualify for the advanced manufacturing production credit under Section 45X of the of the Code and (ix) rely on third - party warranties; (2) the concentration of T1's operations in Texas and its dependence on a limited number of suppliers; (3) changes adversely affecting the flow of components and materials from international vendors, the costs of raw materials, components, equipment, and machinery; (4) general economic and geopolitical conditions, 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 T1's products and competitive position; (5) the outcome of any legal proceedings relating to T1's products and services, including intellectual property or product liability claims, commercial or contractual disputes, warranty claims, and other proceedings; and (6) the capital - intensive nature of T1's business and its ability to raise additional capital on attractive terms or service its debt. All the above referenced filings are available on the SEC’s website at www.sec.gov. Forward - looking statements speak only as of the date of this presentation and are based on information available to T1 as of the date of this press release, and T1 assumes no obligation to update such forward - looking statements, all of which are expressly qualified by the statements in this section, whether as a result of new information, future events or otherwise, except as required by law. Use of Non - GAAP Financial Measures T1 reports financial results in accordance with generally accepted accounting principles in the United States (“GAAP”). Adjusted EBITDA presented herein is a supplemental measure of T1’s performance that is not required by, or presented in accordance with, GAAP. The presentation of this non - GAAP financial measure is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. T1 defines Adjusted EBITDA as net income (loss) from continuing operations before interest expense, income tax expense (benefit), depreciation and amortization, and further adjusted to exclude certain items that management does not consider indicative of the Company’s core operating performance, including, but not limited to, non - cash charges, non - recurring items, and non - operating gains or losses. These adjustments include impairment charges, losses on debt extinguishment, losses on settlement of derivative liabilities, share - based compensation, fair value adjustments of warrant and derivative liabilities, and non - recurring transaction expenses. Our Adjusted EBITDA measure was re - defined in the fourth quarter of 2025 to also exclude certain non - recurring transaction expenses. The historical presentation of Adjusted EBITDA in this presentation has been recast to conform to the revised definition. T1 uses Adjusted EBITDA as a key measure in evaluating its financial and operating performance and in making strategic business decisions. T1 believes that Adjusted EBITDA, when considered together with the corresponding GAAP financial measures, provides meaningful supplemental information by excluding items that may not be representative of its core business, operating results, or future outlook. However, Adjusted EBITDA is not a measure of financial performance under GAAP and should not be considered as an alternative to net income (loss) from continuing operations or any other measure of performance or liquidity presented in accordance with GAAP. Adjusted EBITDA has been reconciled to the nearest GAAP measure for historical periods in the table entitled “Reconciliation of Non - GAAP Measures to Most Comparable Amounts” set forth on Annex A of in T1’s Q4 and Full - Year 2025 results press release published on March 31, 2026. However, T1 is unable to provide a reconciliation for the forward - looking Adjusted EBITDA guidance because it does not currently have sufficient information to accurately estimate all of the variables and individual adjustments for such reconciliation. As such, T1’s management cannot estimate on a forward - looking basis without unreasonable effort the impact these variables and individual adjustments will have on its reported results.
