**Item 4.01. Changes in Registrant's Certifying Accountant.**

On September 5, 2025, the Audit and Risk Committee (the "<u>Committee</u>") of the Board of Directors of T1 Energy Inc. (the "<u>Company</u>") (i) approved the dismissal of PricewaterhouseCoopers AS ("<u>PwC Norway</u>") as the Company's independent registered public accounting firm and (ii) appointed KPMG LLP ("<u>KPMG</u>") as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2025, including performing reviews of the interim periods beginning with the period ending September 30, 2025.

The audit reports of PwC Norway on the Company's consolidated financial statements as of and for the fiscal years ended December 31, 2024 and 2023 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal years ended December 31, 2024 and 2023, and the subsequent interim period through September 5, 2025, there were no: (i) "disagreements," as that term is defined in Item 304(a)(1)(iv) of Regulation S-K under the Securities Act of 1933 ("<u>Regulation S-K</u>") with PwC Norway on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PwC Norway, would have caused PwC Norway to make reference to the subject matter of such disagreements in connection with its audit reports on the Company's consolidated financial statements as of and for the fiscal years ended December 31, 2024 and 2023, or (ii) reportable events within the meaning of Item 304(a)(1)(v) of Regulation S-K, other than, as previously disclosed in an amendment to the Company's Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2025, a material weakness in internal control over financial reporting related to its controls over applying technical accounting guidance to nonrecurring events and transactions, including the design and maintenance of effective controls to evaluate the appropriate presentation of the amortization of intangible assets related to certain customer contracts within our statements of operations and comprehensive income (loss). To remediate this material weakness, the Company's management is working with consultants to establish controls and protocols relating to the appropriate recognition and presentation of certain acquired assets and liabilities and related transactions.

The Company has provided PwC Norway with a copy of the disclosures in this Current Report on Form 8-K, and requested that PwC Norway provide the Company with a letter addressed to the U.S. Securities and Exchange Commission (the "<u>SEC</u>") stating whether PwC Norway agrees to the statements made by the Company herein. A copy of the letter from PwC Norway addressed to the SEC and dated as of September 5, 2025 is filed as Exhibit 16.1 to this Current Report on Form 8-K.

During the fiscal years ended December 31, 2024 and 2023, and the subsequent interim period through September 5, 2025, neither the Company nor anyone on the Company's behalf consulted with KPMG with respect to either (i)(a) the application of accounting principles to a specified transaction, either completed or proposed, or (b) the type of audit opinion that might be rendered on the Company's consolidated financial statements, and neither a written report nor oral advice was provided by KPMG to the Company that KPMG concluded was an important factor that the Company consider in reaching a decision as to any accounting, auditing or financial reporting issue, or (ii) any other matter that was the subject of a "disagreement" or a "reportable event" (as these terms are defined in Item 304(a)(1) of Regulation S-K and the related instructions).
