YHN Acquisition I Limited called an Annual Meeting to seek shareholder approval for two amendments that would allow up to three extensions of its deadline to complete a business combination, each for three months, moving the termination date from December 19, 2025 to September 19, 2026. Each extension requires a $150,000 deposit into the trust account, funded as a non‑interest bearing loan from the sponsor and repayable at closing of a business combination.
The Company entered into a Business Combination Agreement with Mingde Technology Limited on April 3, 2025. Public shareholders retain redemption rights for a pro rata share of the trust, calculated as of two business days prior to the meeting. The Company will not proceed with the extensions if redemptions would cause net tangible assets to fall below $5,000,001. If the proposals fail and no business combination closes by December 19, 2025, the trust will be liquidated and public rights will expire worthless. Shares outstanding entitled to vote total 7,750,000.
