Item 3.02 Unregistered Sales of Equity Securities.

As previously reported, on December 8, 2025, 5E Advanced Materials, Inc., a Delaware corporation (the “Company”), held its 2025 annual meeting of stockholders, at which the Company’s stockholders approved the Company’s entry into an agreement (the “Letter Agreement”) to issue warrants to purchase shares of the Company’s common stock, par value $0.01 (the “Common Stock”), to BEP Special Situations IV LLC and Ascend Global Investment Fund SPC for and on behalf of Strategic SP, or their respective affiliates (the “Guarantors”) in connection with the Company’s potential $10.0 million funding package (the “EXIM Loan”) from the Export-Import Bank of the United States.

On January 7, 2026, the Company and the Guarantors entered into the Letter Agreement, pursuant to which the Company agreed to issue warrants (the “Warrants”) to purchase up to $10.0 million of Common Stock in exchange for the Guarantors agreeing to provide a guarantee for the EXIM Loan. On January 7, 2026, the Company issued the Warrants pursuant to the Letter Agreement.

The Warrants have an exercise price of $3.5507 per share, subject to customary adjustments in the event of any stock split, stock dividend, stock combination, recapitalization or similar transaction. The Warrants will not be exercisable, if ever, until the date that the Guarantors provide the Guarantee, at which time each Guarantor’s Warrant will be exercisable for a notional amount of Common Stock equal to the amount guaranteed by such Guarantor. The aggregate notional value of the Warrants will not exceed $10.0 million, and the maximum number of shares issuable under all Warrants is 2,816,346.

The Warrants will terminate upon the earlier of (a) the second anniversary of the date that the EXIM Loan is repaid or (b) the release of the Guarantee.

The Warrants were offered and issued in a private placement exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended.

In the event that the Company does not obtain the EXIM Loan or the Guarantee is not provided, the Warrants will not vest or become exercisable for any shares of Common Stock.
