Rhea-AI Filing Summary

Crown PropTech Acquisitions announced that the SEC declared effective on November 4, 2026, the Form F-4 registration statement filed by Mkango Rare Earths Limited, a wholly owned subsidiary of Mkango Magnetic Materials Limited, for their proposed business combination. CPTK expects to begin mailing the updated definitive proxy statement/prospectus on or about November 5, 2026, to shareholders of record as of October 30, 2026.

CPTK’s extraordinary general meeting is scheduled for November 25, 2026, at 10:00 a.m. Eastern Time. Public shareholders seeking cash redemption must submit a request and deliver their shares by 5:00 p.m. Eastern Time on November 23, 2026, in accordance with the prospectus procedures. Completion is subject to CPTK shareholder approval and satisfaction or waiver of other closing conditions, including Nasdaq approval of MKAR’s initial listing application. Nasdaq has not approved that application. If completed, MKAR common shares and warrants are expected to list under the symbols MKAR and MKARW.

Filing Explained

Completion also depends on satisfying or waiving a minimum-cash condition after redemptions; the release identifies a possible PIPE as financing but says none is assured, so the cash available at closing remains unresolved.

5 terms

Form F-4 regulatory

"registration statement on Form F-4"

Form F-4 is an official filing with the U.S. Securities and Exchange Commission used by non-U.S. companies when they offer securities in connection with mergers, acquisitions, exchange offers or similar transactions. It acts like a detailed product label or instruction manual that explains the deal, the securities being offered, financials, risks and voting requirements, and it matters to investors because it provides the essential facts needed to evaluate how the transaction could affect ownership, value and future returns.

definitive proxy statement/prospectus regulatory

"mailing the definitive proxy statement/prospectus"

The definitive proxy statement/prospectus is the final, official document filed with regulators that gives shareholders or potential investors the complete, legally required information about a corporate action—such as votes on governance issues or the sale of securities. Think of it as the final recipe or instruction manual that lays out the terms, financial details, risks and voting or investment choices; investors use it to make informed decisions because it contains the authoritative facts the company must disclose.

record date regulatory

"the record date for CPTK’s extraordinary general meeting"

The record date is the specific day when a company determines which shareholders are eligible to receive a dividend or participate in an upcoming vote. It’s like a cutoff date; if you own the stock on that day, you get the benefits or voting rights. This date matters because it decides who qualifies for certain company benefits.

minimum cash condition financial

"the conditions precedent to closing, including the minimum cash condition"

A minimum cash condition is a contract clause that requires a company to hold at least a specified amount of cash or liquid assets before a transaction can close or a financing can proceed. Investors care because it protects against deals being completed when the business lacks enough cash to operate or meet short-term obligations—think of it as a safety buffer like keeping a minimum balance in a bank account so you don’t bounce payments after a big purchase.

PIPE financing financial

"the failure to complete any PIPE financing"

Pipe financing is a way for companies to raise money quickly by selling new shares or bonds directly to investors, often before their stock is publicly traded or in the early stages of a project. It’s similar to a company securing a loan from investors, providing quick capital needed for growth or operations. For investors, it can offer opportunities for early involvement and potentially higher returns, but it may also carry increased risk due to the immediate nature of the deal.

MKANGO MAGNETIC MATERIALS LIMITED ANNOUNCES EFFECTIVENESS OF FORM F-4
REGISTRATION STATEMENT AND MAILING OF CPTK PROXY STATEMENT/PROSPECTUS

VANCOUVER, BC AND LONDON, UK / ACCESS Newswire / November 5, 2026 / Mkango Magnetic Materials Limited (formerly Mkango Resources Ltd.) (AIM:MKA) (TSXV:MKA) (“Mkango”) announces that the registration statement on Form F-4 (as amended, the “Form F-4”) filed by its wholly-owned subsidiary, Mkango Rare Earths Limited (f/k/a Lancaster Exploration Limited) (“MKAR”), with the United States Securities and Exchange Commission (the “SEC”) was declared effective by the SEC on November 4, 2026. The Form F-4 was filed in connection with the proposed business combination between MKAR and Crown PropTech Acquisitions (OTC:CPTKW) (“CPTK”) (the “Proposed Business Combination”), initially announced on July 3, 2025.

CPTK expects to commence mailing the definitive proxy statement/prospectus (the “Proxy Statement/Prospectus”), which was updated from the preliminary proxy statement/prospectus included in the Form F-4, on or about November 5, 2026 to its shareholders of record as at the close of business on October 30, 2026, which is the record date for CPTK’s extraordinary general meeting to consider and vote on the Proposed Business Combination and related proposals (the “Extraordinary General Meeting”). The Extraordinary General Meeting is scheduled to be held on November 25, 2026 at 10:00 a.m. (Eastern Time) at CPTK’s offices. CPTK public shareholders who wish to request CPTK to redeem their shares for cash upon the consummation of the Proposed Business Combination must submit the applicable request and deliver the shares by 5:00 p.m. (Eastern Time) on November 23, 2026 (two business days prior to the vote and the Extraordinary Meeting) in accordance with the procedures set out in the Proxy Statement/Prospectus.

The Proxy Statement/Prospectus filing by CPTK is available on EDGAR at the following hyperlink: https://www.sec.gov/ix?doc=/Archives/edgar/data/0001827899/000121390026116022/ea0310952-01.htm A substantively equivalent prospectus filing by MKAR is available on EDGAR at the following hyperlink: https://www.sec.gov/Archives/edgar/data/2052373/000121390026116017/ea0271516-18.htm, is filed under Mkango’s profile on SEDAR+ at www.sedarplus.ca, and has been delivered to Mkango as sole shareholder of MKAR. Subject to approval by CPTK’s shareholders and satisfaction or waiver of the other closing conditions, including approval of MKAR’s listing application by Nasdaq, MKAR’s common shares and warrants are expected to list on Nasdaq under the symbols “MKAR” and “MKARW” on closing. Nasdaq has not yet approved MKAR’s initial listing application, and there can be no assurance that it will do so.

Alexander Lemon, President of Mkango, commented: “The SEC’s declaration of effectiveness of the Form F-4 registration statement marks a key milestone in our proposed business combination with Crown PropTech Acquisitions. With the definitive proxy statement/prospectus now being mailed to CPTK shareholders, our focus turns to completing the business combination and listing on Nasdaq of Mkango Rare Earths Limited (MKAR), which would hold the Songwe Hill rare earths project in Malawi and the proposed Pulawy rare earths separation plant in Poland.”

None of the Form F-4, the Proxy Statement/Prospectus, or MKAR’s equivalent prospectus filing (collectively, the “Filings”) has been reviewed or approved by any Canadian or United Kingdom regulatory authority, constitutes a prospectus under Canadian or United Kingdom securities laws, or constitutes an offer of securities in those jurisdictions. The content of the Filings has not been approved by an authorised person within the meaning of the United Kingdom Financial Services and Markets Act 2000. Technical and scientific information in the Filings has been prepared in accordance with Regulation S-K under United States securities laws, which differs from National Instrument 43-101 – Standards of Disclosure for Mineral Projects. Canadian readers are referred to Mkango’s “NI 43-101 Updated Technical Report on the Songwe Hill Rare Earth Element Project in Malawi”, with an effective date of June 30, 2025, filed on SEDAR+ on October 26, 2026.

About Mkango Magnetic Materials Limited

Mkango is listed on the AIM and the TSX-V Stock Exchanges. Mkango’s corporate strategy is to become a market leader in the production of recycled rare earth magnets, alloys and oxides, through its interest in Maginito Limited (“Maginito”), which is owned 79.4 percent by Mkango and 20.6 per cent by CoTec Holdings Ltd (“CoTec”), and the Remloy business acquired by its wholly owned German subsidiary, to develop new sustainable sources of neodymium, praseodymium, dysprosium and terbium to supply accelerating demand from electric vehicles, wind turbines and other clean energy technologies.

Maginito holds a 100 percent interest in HyProMag Limited and a 90 percent indirect interest in HyProMag GmbH, focused on short loop rare earth magnet recycling and manufacturing in the UK and Germany, respectively, and a 100 per cent interest in Mkango Rare Earths UK Ltd (“Mkango UK”), focused on long loop rare earth magnet recycling in the UK via a chemical processing route.

Maginito and CoTec are also expanding HPMS recycling technology into the United States via the 50/50 owned HyProMag USA joint venture company.

Remloy has developed a plant in Bitterfeld, Germany, which recycles end-of-life rare earth magnets via a melting process (medium loop rare earth magnet recycling) to produce neodymium-iron-boron (“NdFeB”) alloy powders for the bonded and hot deformed magnet markets, complementary to HyProMag’s short loop recycling process, to produce sintered magnets, and to Mkango UK’s long loop recycling process, to produce mixed rare earth carbonates and oxides.

Mkango currently owns 100 percent of the advanced stage Songwe Hill rare earths project in Malawi and the proposed Pulawy rare earths separation plant in Poland. On grant of the large-scale mining licence the Government of Malawi may elect to take a free 10 percent interest in the entity holding that licence. Both the Songwe and Pulawy projects have been selected as Strategic Projects under the European Union Critical Raw Materials Act, as has HyProMag GmbH. Songwe has also received Development Funding from the U.S. International Development Finance Corporation (DFC), the U.S. Government’s development finance institution, securing US$4.6 million in reimbursable funding for Front End Engineering and Design. MKAR has signed a Business Combination Agreement with CPTK, pursuant to which MKAR, which will hold the Songwe Hill and Pulawy projects, is expected to become listed on Nasdaq, subject to the satisfaction or waiver of closing conditions.

Actual results may vary materially if these assumptions prove incorrect.

Readers are cautioned not to place undue reliance on forward-looking statements. Factors and risks that could cause actual results to differ materially include, without limitation: the failure to complete the Proposed Business Combination on the terms or within the timeframe contemplated, or at all, or by CPTK’s business combination deadline, and the failure to obtain any extension of that deadline; the failure to satisfy or obtain waiver of the conditions precedent to closing, including approval by Mkango and CPTK’s shareholders, satisfaction of the minimum cash condition following redemptions, and receipt of required governmental, regulatory, stock exchange, court and other third party approvals; the level of redemptions by CPTK’s public shareholders and the cash available on closing; the inability to obtain additional financing on favourable terms, in an amount sufficient to satisfy the minimum cash condition, or at all; the exercise of termination rights under the Amended and Restated Business Combination Agreement; the failure to obtain approval of MKAR’s initial listing application from Nasdaq, including as a result of the failure to obtain quotation of CPTK’s Class A ordinary shares on the OTC Markets or to meet Nasdaq’s market value and public float requirements; the failure to complete any PIPE financing, or to complete it in an amount or on terms sufficient to satisfy the minimum cash condition; volatility in the price of MKAR’s securities; market risks, including the price of rare earth materials; the effect of the announcement or pendency of the Proposed Business Combination on business relationships and performance; litigation, regulatory proceedings or shareholder actions arising in connection with the Proposed Business Combination; the consequences of the Proposed Business Combination for Mkango’s interests in Songwe Hill and Pulawy and for Mkango’s status on AIM and the TSX-V; and the anticipated benefits of the Proposed Business Combination not being realised in whole or in part.

There can be no assurance that Nasdaq will approve MKAR’s listing application, that any PIPE financing will be completed or as to its size or terms, or that the Proposed Business Combination will be completed.

The foregoing list is not exhaustive. Readers should also consider the risks described in CPTK’s filings with the SEC, Mkango’s filings on SEDAR+, and the Proxy Statement/Prospectus.
