NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART, DIRECTLY OR INDIRECTLY, IN, INTO OR FROM ANY JURISDICTION WHERE TO DO SO WOULD CONSTITUTE A VIOLATION OF THE RELEVANT LAWS OR REGULATIONS OF SUCH JURISDICTION

THE FOLLOWING ANNOUNCEMENT IS BEING MADE PURSUANT TO THE REQUIREMENTS OF RULES 19.6(B) OF THE CITY CODE ON TAKEOVERS AND MERGERS (THE "CODE")

FOR IMMEDIATE RELEASE

29 July 2026

AMG Lithium B.V. ("AMG Lithium")

a direct wholly-owned subsidiary of AMG Critical Materials N.V. ("AMG")

Rule 19.6(b) update to post-offer intention statements with regard to Zinnwald Lithium PLC ("Zinnwald Lithium")

AMG Lithium refers to its recommended acquisition of the entire issued and to be issued share capital of Zinnwald Lithium, which was implemented by way of a scheme of arrangement under Part 26 of the Companies Act 2006 and which became effective on 27 July 2026 (the "Acquisition").

In accordance with Rule 19.6(b) of the Code, AMG Lithium announces an update to the statements of intent made pursuant to Rules 2.7(c)(viii) and 24.2(a)(ii) to (iii) of the Code (the "Stated Intentions"), as set out in the announcement issued on 14 May 2026 and the scheme document published on 11 June 2026 (together, the "Offer Documentation").

As set-out in the Offer Documentation, AMG Lithium intended to close Zinnwald Lithium's headquarters in London. In addition, once Zinnwald Lithium ceased to be a listed company, public company-related functions, as well as certain corporate, support and headquarter functions at the Zinnwald Lithium Group's office in London, would become unnecessary, and these functions were therefore intended to be reduced in scope. It was noted that these job reductions could be material in the context of Zinnwald Lithium Group only having 14 employees.

The Acquisition became effective on 27 July 2026, Zinnwald Lithium ceased to be a listed company and AMG Lithium have concluded to close Zinnwald Lithium's headquarters in London.

AMG Lithium now updates that Anton du Plessis (Chief Executive Officer) has stepped down from the Zinnwald Lithium Board and ceased to be a director of, and employed by, Zinnwald Lithium with effect from 29 July 2026.

Capitalised terms used in this announcement shall, unless otherwise defined, have the same meanings as set out in the Offer Documentation.
