Next steps

It is anticipated that the Effective Date will be 27 July 2026, which is when a copy of the Court Order (together with a copy of the Scheme and all documents required to be annexed thereto) is expected to be delivered to the Registrar of Companies.

There has been no change to the expected timetable of principal events for the Acquisition set out in the announcement made by Zinnwald Lithium on 13 July 2026. If any of the dates and/or times in the expected timetable change, Zinnwald Lithium will give notice of the changes by issuing an announcement through a Regulatory Information Service and by posting notice of these dates on the following website: www.zinnwaldlithium.com/investors/project-disclaimer/.

Overseas Shareholders

The release, publication or distribution of this Announcement in or into or from certain jurisdictions other than the United Kingdom may be restricted by the laws of those jurisdictions. Persons who are not resident in the United Kingdom or who are subject to the laws of other jurisdictions into whose possession this document (and the accompanying documents) come should inform themselves about, and observe, any such restrictions. Any failure to comply with any such restrictions may constitute a violation of the securities laws of any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility and liability for the violation of such restrictions by any person.

Unless otherwise determined by AMG and/or AMG Lithium or required by the Code, and permitted by applicable law and regulation, the Acquisition and the Offer will not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction. Accordingly, copies of this Announcement and all documents relating to the Acquisition and the Offer are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in, into or from any Restricted Jurisdiction where to do so would violate the laws in that jurisdiction, and persons receiving this Announcement and all documents relating to the Acquisition and the Offer (including custodians, nominees and trustees) must not mail or otherwise forward, distribute or send them in, into or from any Restricted Jurisdiction.

The availability of the Acquisition and the Offer to Scheme Shareholders who are not resident in the United Kingdom may be affected by the laws of the relevant jurisdictions in which they are resident. Persons who are not resident in the United Kingdom should inform themselves of, and observe, any applicable legal or regulatory requirements of their jurisdictions.

Further details in relation to Overseas Shareholders are contained in the Scheme Document.

Additional information for U.S. investors

The Acquisition relates to the shares of a company incorporated in England and Wales and has been implemented by means of a scheme of arrangement under the laws of England and Wales. A transaction implemented by means of a scheme of arrangement is not subject to the tender offer rules or the proxy solicitation rules under the U.S. Exchange Act and other requirements of U.S. law.

Accordingly, the Acquisition is subject to the disclosure and procedural requirements applicable in the United Kingdom to schemes of arrangement which differ from the disclosure requirements of the United States' tender offer and proxy solicitation rules.

Financial information relating to Zinnwald Lithium included in the Scheme Document has been or shall have been prepared in accordance with accounting standards applicable in the United Kingdom and may not be comparable to financial information of U.S. companies or companies whose financial statements are prepared in accordance with U.S. GAAP. U.S. GAAP differs in certain significant respects from accounting standards applicable in the United Kingdom.

The receipt of consideration by a U.S. Holder for the transfer of its Zinnwald Lithium Shares pursuant to the Scheme may have tax consequences in the United States. Each Zinnwald Lithium Shareholder is urged to consult their independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to them, including under applicable United States state, federal and local, as well as overseas and other tax laws.

AMG and AMG Lithium are organised under the laws of the Netherlands. Zinnwald Lithium is organised under the laws of England and Wales. Some or all of the officers and directors of AMG, AMG Lithium and Zinnwald Lithium, respectively, are residents of countries other than the United States. In addition, all of the assets of Zinnwald Lithium are located outside the United States. As a result, it may be difficult for U.S. shareholders of Zinnwald Lithium to effect service of process within the United States upon AMG, AMG Lithium or Zinnwald Lithium or their respective officers or directors or to enforce against them a judgment of a U.S. court predicated upon the federal or state securities laws of the United States. Further, it may be difficult to compel a non-U.S. company and its affiliates to subject themselves to a U.S. court's judgment.

The New AMG Shares have not been, and will not be, registered under the U.S. Securities Act, or applicable state securities laws. The New AMG Shares will not be issued to Scheme Shareholders unless AMG and/or AMG Lithium determines that they may be issued pursuant to an exemption from, or in a transaction that is not subject to, the registration requirements of the U.S. Securities Act as provided by Section 3(a)(10) of the U.S. Securities Act or another available exemption.

The New AMG Shares are expected to be issued in reliance on the exemption from the registration requirements of the U.S. Securities Act set forth in Section 3(a)(10) thereof on the basis of the approval of the Court, and similar exemptions from registration under applicable state securities laws. Section 3(a)(10) of the U.S. Securities Act exempts the issuance of any securities issued in exchange for one or more bona fide outstanding securities from the general requirement of registration under the U.S. Securities Act, where the terms and conditions of the issuance and exchange of such securities have been approved by a court of competent jurisdiction that is expressly authorised by law to grant such approval, after a hearing upon the substantive and procedural fairness of the terms and conditions of such issuance and exchange at which all persons to whom it is proposed to issue the securities have the right to appear and receive timely and adequate notice thereof. The Court is authorised to conduct a hearing at which the substantive and procedural fairness of the terms and conditions of the Scheme were considered. For the purposes of qualifying for the exemption provided by Section 3(a)(10) of the U.S. Securities Act, Zinnwald Lithium advised the Court before the hearing that the Court's approval of the Scheme will constitute the basis for an exemption from the registration requirements of the U.S. Securities Act, pursuant to Section 3(a)(10).

If, in the future, AMG Lithium exercises its right to implement the Acquisition by way of a Takeover Offer or otherwise in a manner that is not exempt from the registration requirements of the U.S. Securities Act, it would be necessary for AMG to file a registration statement with the SEC that would contain a prospectus with respect to the issuance of the New AMG Shares under the U.S. Securities Act. Should this occur, Zinnwald Lithium Shareholders are urged to read these documents and any other relevant documents (as well as any amendments or supplements to those documents) because they would contain important information, and such documents would be available free of charge at the SEC's website at www.sec.gov or by directing a response to AMG's contact for enquiries identified above. In addition, if AMG Lithium exercises its right to implement the Acquisition by way of a Takeover Offer, which is to be made into the United States, such Takeover Offer would need to be made in compliance with the applicable laws of the United States and regulations, including Section 14(e) and Regulation 14E of the U.S. Exchange Act.

The New AMG Shares issued to persons other than "affiliates" (defined as certain control persons, within the meaning of Rule 144 under the U.S. Securities Act) of AMG will be freely transferable under the laws of the United States after the Acquisition. Persons (whether or not U.S. Persons) who are or will be "affiliates" of AMG within 90 days prior to the Effective Date, or of AMG at any time after the Effective Date, will be subject to certain transfer restrictions relating to the New AMG Shares under applicable U.S. laws and regulations. Whether a person is an "affiliate" of a company for such purposes depends upon the circumstances, but "affiliates" of a company can include certain officers and directors and significant shareholders. Scheme Shareholders who believe they may be "affiliates" for the purposes of the U.S. Securities Act should consult their own legal advisers prior to any resale of New AMG Shares received under the Scheme.

In accordance with normal UK practice and pursuant to Rule 14e-5(b) of the U.S. Exchange Act, AMG and/or AMG Lithium and certain of its affiliated companies or nominees, or its or their brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, Zinnwald Lithium Shares outside of the United States, other than pursuant to the Acquisition, until the date on which the Acquisition becomes Effective, lapses or is otherwise withdrawn. If such purchases or arrangements to purchase were to be made, they would occur either in the open market at prevailing prices or in private transactions at negotiated prices and would comply with applicable law, including the laws of the United Kingdom and the U.S. Exchange Act. Any information about such purchases will be disclosed as required in the United Kingdom, will be reported to a Regulatory Information Service and will be available on the London Stock Exchange website, www.londonstockexchange.com. To the extent that such information is required to be publicly disclosed in the United Kingdom in accordance with applicable regulatory requirements, this information will, as applicable, also be publicly disclosed in the United States.

THE SCHEME AND THE NEW AMG SHARES TO BE ISSUED IN CONNECTION THEREWITH HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SEC OR ANY OTHER SECURITIES REGULATORY AUTHORITY OF ANY STATE OF THE UNITED STATES, NOR HAS THE SEC OR ANY SECURITIES REGULATORY AUTHORITY OF ANY STATE OF THE UNITED STATES PASSED UPON THE FAIRNESS OR THE MERITS OF THIS TRANSACTION OR UPON THE ACCURACY OR ADEQUACY OF THE INFORMATION CONTAINED IN THIS ANNOUNCEMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.
