Mkango Resources Ltd (AIM/TSXV: MKA) has taken another step towards the proposed Nasdaq listing of its rare earths subsidiary after filing an amended Form F-4 with US regulators and announcing non-redemption agreements involving funds managed by BlackRock subsidiaries.
Mkango Rare Earths Limited, or MKAR, filed the amended registration statement with the US Securities and Exchange Commission on 3 September as part of its proposed business combination with Crown PropTech Acquisitions.
Subject to completion of the SEC review, shareholder approval and other closing conditions, MKAR’s shares and warrants are expected to list on Nasdaq under the symbols MKAR and MKARW.
Separately, Crown PropTech and its sponsor have entered eight non-redemption agreements with funds and accounts managed by subsidiaries of BlackRock covering 400,000 Crown PropTech public shares.
The agreements are expected to retain at least US$4.8 million in Crown PropTech’s trust account, substantially contributing towards the US$5 million minimum cash condition required for completion of the business combination.
The investors will receive modified transfer restrictions on securities assigned to them in return for agreeing not to redeem the shares at the extraordinary general meeting considering the transaction.
MKAR has also entered into an amended and restated business combination agreement consolidating previous amendments made since the original agreement was signed in July 2025.
Mkango said the material economic terms of the proposed transaction remain unchanged.
The amended Form F-4 remains subject to SEC review and has not yet been declared effective, meaning completion of the Nasdaq transaction remains subject to regulatory, shareholder and other customary conditions.
Mkango president Alexander Lemon said the filing, non-redemption agreements and amended business combination agreement represented a significant milestone towards completing the transaction and securing MKAR’s expected Nasdaq listing.
