Explanatory Note

This Amendment No. 4 to Schedule 13D amends and supplements the statement on Schedule 13D filed with the United States Securities and Exchange Commission on January 29, 2024 (as amended to date, the “Schedule 13D”), relating to the common stock, par value $0.01 per share (the “Common Stock”), of 5E Advanced Materials, Inc., a Delaware corporation (the “Issuer”). Capitalized terms used herein without definition shall have the meaning set forth in the Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration.

On September 16, 2024, Ascend Global and Meridian each purchased $1.5 million of the September 2024 Notes (as defined below) from the Issuer. Ascend Global and Meridian obtained the funds to purchase the September 2024 Notes through capital contributions from their partners and shareholders, respectively, including the other Reporting Persons.

Item 4. Purpose of Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented with the following:

September 2024 Notes Purchase

On September 16, 2024, and as contemplated by the previously disclosed Debt Commitment Letter, the Issuer entered into a third amendment (“Amendment No. 3”) to its Amended and Restated Note Purchase Agreement, dated as of January 18, 2024, by and among the Issuer, BEP, Ascend Global, Meridian and Alter Domus (US) LLC, as collateral agent, related to the Issuer’s 4.50% senior secured convertible promissory notes.

Pursuant to Amendment No. 3, on September 16, 2024, the Issuer (i) issued and sold $6.0 million aggregate principal amount of convertible notes (the “September 2024 Notes” and, collectively with the Existing Notes, the “Notes”) to BEP, Ascend Global and Meridian (collectively, the “Purchasers”), comprised of $3.0 million of September 2024 Notes to BEP and $1.5 million of September 2024 Notes to each of Ascend Global and Meridian and (ii) amended and restated the Note Purchase Agreement in the form attached as Annex A to Amendment No. 3 (the “Amended and Restated Note Purchase Agreement”).

The September 2024 Notes, which were issued in substantially the same form as the Existing Notes, bear interest at a rate of 4.50% per annum, payable semi-annually beginning on February 15, 2025, or 10.00% per annum if the Issuer elects to pay such interest in kind through the delivery of additional Notes, and are initially convertible into an aggregate of 6,400,001 shares of the Issuer’s Common Stock, at a conversion rate of 1066.6667 shares of Common Stock per $1,000 principal amount of Notes (the “Conversion Rate”), representing a conversion price of $0.9375 per share.

The Conversion Rate for the September 2024 Notes is subject to adjustment in accordance with the terms of the Amended and Restated Note Purchase Agreement, including in connection with certain change of control transactions or other events specified in the Amended and Restated Note Purchase Agreement

CUSIP No. 33830Q109 13D Page 7 of 9 pages

Third Amended and Restated Investor and Registration Rights Agreement

In connection with the issuance and sale of the September 2024 Notes and pursuant to Amendment No. 3, the Issuer entered into the Third Amended and Restated Investor and Registration Rights Agreement (the “Third Amended and Restated IRRA”) by and among the Issuer, BEP, Ascend Global and Meridian. Pursuant to the Third Amended and Restated IRRA, the Issuer granted the Purchasers registration rights for the shares of Common Stock underlying the September 2024 Notes, which are substantially similar to those granted under the Amended and Restated IRRA with respect to the shares of Common Stock underlying the Existing Notes.

The Third Amended and Restated IRRA continues to provide the parties thereto with substantially the same director nomination rights set forth in the Amended and Restated IRRA, whereby each of BEP and Ascend Global (or such person as may be nominated by Ascend Global) has the right, so long as such party beneficially owns (i) at least twenty-five percent (25%) of the outstanding principal amount of the Notes or (ii) at least ten percent (10%) of the outstanding shares of Common Stock, to designate one (1) individual to the Issuer’s board of directors.

The foregoing descriptions of Amendment No. 3 and the Third Amended and Restated IRRA do not purport to be complete and are qualified in their entirety by the full text of the agreement, which are each included as an exhibit to this Schedule 13D.
