YHN Acquisition I Limited reported that it has signed Amendment No. 2 to its Amended and Restated Business Combination Agreement with Mingde Technology Limited, extending the Outside Closing Date for their proposed business combination to June 18, 2026. The deal structure still contemplates a reincorporation merger and a subsequent acquisition merger that would make Mingde a wholly owned subsidiary of a Nasdaq-listed purchaser.
The disclosure reiterates that completion of the transaction depends on conditions such as shareholder approval and other closing requirements, and includes extensive cautionary language about forward-looking statements. Risks highlighted include the possibility the business combination may not be completed, potential legal proceedings, uncertainty around redemptions by public shareholders, and competition and regulatory changes affecting Mingde’s business.
On December 15, 2025, YHN Acquisition I Limited deposited $150,000 into its trust account to extend the time it has to complete a business combination. This payment shifts the deadline for closing a transaction from December 19, 2025 to March 19, 2026, giving the company an additional three months to pursue and finalize a suitable deal.
YHN Acquisition I Limited is asking shareholders to approve changes to its charter and trust agreement so it can extend the deadline to complete its initial business combination up to three times, in three-month increments, from December 19, 2025 to September 19, 2026. For each three-month extension, the sponsor or its affiliates is expected to lend $150,000 to the company, which will be deposited into the trust account as an extension payment and repaid only if a business combination closes. As of November 12, 2025, the trust account held about $63.3 million, implying an estimated redemption price of roughly $10.55 per public share. Public shareholders may redeem their shares for cash in connection with the vote, but if the amendments are not approved and no deal closes by December 19, 2025, the SPAC must liquidate, return the remaining trust funds to public holders and allow its rights and warrants to expire worthless.
