Mkango Magnetic Materials Limited (AIM: MKA, TSXV: MKA) has announced that the United States Securities and Exchange Commission declared its Form F-4 registration statement effective on 4 November 2026, marking a significant regulatory milestone in the proposed business combination between its wholly-owned subsidiary Mkango Rare Earths Limited (MKAR) and Crown PropTech Acquisitions (OTC: CPTKW). The definitive proxy statement and prospectus is being mailed to CPTK shareholders of record as at 30 October 2026, with an extraordinary general meeting scheduled for 25 November 2026. A successful combination would see MKAR list on Nasdaq under the symbols "MKAR" and "MKARW", holding the Songwe Hill rare earths project in Malawi and the proposed Pulawy rare earths separation plant in Poland.

Key Points

  • Mkango Magnetic Materials Limited (AIM: MKA, TSXV: MKA), formerly Mkango Resources Ltd.
  • The SEC declared the Form F-4 registration statement effective on 4 November 2026, enabling the mailing of the definitive proxy statement and prospectus to CPTK shareholders.
  • CPTK's extraordinary general meeting to vote on the proposed business combination is scheduled for 25 November 2026 at 10:00 a.m. Eastern Time; shareholders wishing to redeem shares must submit requests by 23 November 2026.
  • Investors should watch for CPTK shareholder approval, satisfaction of closing conditions, and Nasdaq's decision on MKAR's initial listing application, which has not yet been approved.

SEC Declares Mkango Rare Earths Form F-4 Effective, Triggering CPTK Proxy Mailing

The SEC's declaration of effectiveness on 4 November 2026 clears a critical regulatory hurdle for the proposed business combination, first announced on 3 July 2025, between MKAR and Crown PropTech Acquisitions. CPTK commenced mailing the definitive proxy statement and prospectus on or about 5 November 2026 to shareholders of record at the close of business on 30 October 2026. President Alexander Lemon stated in the announcement that the SEC's decision "marks a key milestone" and that the company's focus now turns to completing the business combination and achieving a Nasdaq listing for MKAR.

Songwe Hill Malawi and Pulawy Poland Projects to Transfer Into Nasdaq-Listed MKAR

Upon completion of the proposed business combination, MKAR would hold Mkango's 100 per cent interest in the advanced-stage Songwe Hill rare earths project in Malawi and the proposed Pulawy rare earths separation plant in Poland. Both projects have been designated as Strategic Projects under the European Union Critical Raw Materials Act. Songwe Hill has also received US$4.6 million in reimbursable Development Funding from the U.S. International Development Finance Corporation for Front End Engineering and Design work, as disclosed in the announcement.

CPTK Extraordinary General Meeting Set for 25 November 2026 With Redemption Deadline of 23 November

CPTK's extraordinary general meeting is scheduled for 25 November 2026 at 10:00 a.m. Eastern Time at CPTK's offices. Public shareholders of CPTK who wish to redeem their shares for cash upon consummation of the proposed business combination must submit the applicable request and deliver their shares by 5:00 p.m. Eastern Time on 23 November 2026, two business days prior to the vote, in accordance with the procedures set out in the proxy statement and prospectus. The level of redemptions will affect the cash available on closing, the announcement notes.

Nasdaq Listing Approval for MKAR Remains Pending as a Key Closing Condition

Whilst the SEC's declaration of effectiveness represents meaningful progress, Mkango's announcement explicitly states that Nasdaq has not yet approved MKAR's initial listing application, adding that "there can be no assurance that it will do so." Nasdaq approval is listed among the closing conditions that must be satisfied or waived before the transaction can complete. Mkango is also active in rare earth magnet recycling through its Maginito subsidiary, which holds interests in HyProMag operations across the UK, Germany, and the United States, and operates the Remloy plant in Bitterfeld, Germany. Investors will be monitoring all outstanding conditions closely ahead of the 25 November vote.
