REVERSE STOCK SPLIT TIMETABLE (CDIs)

5E Advanced Materials, Inc. (ASX: 5EA) (the Company ) advises, further to the approval of stockholders at the 2024 Annual Meeting held on January 21, 2025, that the Board has approved a reverse stock split of the Company’s common stock at a final ratio of 1-for-23 (the Reverse Stock Split ).

As a result of the Reverse Stock Split, each 23 CHESS Depositary Interests ( CDIs ) will be consolidated into one CDI.

No fractional shares or CDIs will be issued if, a result of the Reverse Stock Split, a CDI holder would otherwise become entitled to a fraction of a CDI because the number of CDIs they hold before the Reverse Stock Split is not evenly divisible by the 1-for-23 ratio. In these circumstances, fractional entitlements will be rounded down to the nearest whole number (or nil, where the number of CDIs held by a CDI holder on the record date is less than 23). In accordance with applicable Delaware laws, for the purpose of making cash payments in lieu of fractional entitlements, the shares of common stock held by the depositary nominee on behalf of CDI holders will be treated as a single, undivided holding such that any payment in lieu will only be made to the depositary nominee.

An indicative ASX timetable for the Reverse Stock Split in respect of CDIs is set out below.

When used in this press release, the words "believe," "project," "expect," "forecast," "anticipate," "estimate," "intend," "seek," "budget," "target," "aim," "strategy," "plan," "guidance," "outlook," "intent," "may," "should," "could," "will," "would," "will be," "will continue," "will likely result," and similar expressions are intended to identify forwardlooking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on the Company's current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. We caution you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond our control, incident to the extraction of the critical materials we intend to produce and advanced materials production and development. These risks include, but are not limited to: our limited operating history in the borates and lithium industries and no revenue from our proposed extraction operations at our properties; our need for substantial additional financing to continue as a going concern and to execute our business plan and our ability to access capital and the financial markets; our status as an exploration stage company dependent on a single project with no known Regulation S-K 1300 mineral reserves and the inherent uncertainty in estimates of mineral resources; our lack of history in mineral production and the significant risks associated with achieving our business strategies, including our downstream processing ambitions; our incurrence of significant net operating losses to date and plans to incur continued losses for the foreseeable future; risks and uncertainties relating to the development of the Fort Cady project, including our ability to timely and successfully complete our proposed Commercial Scale Boron Facility; our ability to obtain stockholder approval for and successfully implement the Transaction, and related matters on a timely manner or at all; our ability to obtain, maintain and renew required governmental permits for our development activities, including satisfying all mandated conditions to any such permits; the implementation of and expected benefits from certain reduced spending measures, the delisting of our securities from Nasdaq, which could limit investors' ability to transact in our securities, subject us to additional trading restrictions and substantially increase the number of shares issuable upon conversion of our outstanding convertible notes; and other risks and uncertainties set forth in our filings with the SEC from time to time. Should one or more of these risks or uncertainties occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements.
