Charlton Aria Acquisition Corporation filed an 8-K covering a trust deposit that extends its combination window, plus two sponsor promissory notes and a furnished press release. On April 24, 2026, ST Sponsor II Limited deposited $850,000 into the trust account. Under the Second Amended and Restated Memorandum and Articles, the Company had until April 25, 2026 (18 months from IPO) to complete an initial business combination and may extend twice by three months each if the Sponsor or designees deposit $850,000 per extension, up to $1,700,000 aggregate. The deposit sets the new outside date at July 25, 2026. In connection with the extension, the Company issued an unsecured Extension Note dated April 23, 2026 in principal amount $850,000 to the Sponsor. The note bears no interest except default interest at the prevailing short-term U.S. Treasury Bill rate; outstanding principal is payable on the earlier of consummation of the initial business combination or liquidation. On April 17, 2026 the Company also issued an unsecured Working Capital Note to the Sponsor for up to $500,000. The Sponsor had already advanced approximately $263,681.50 as working capital; the note partially evidences those prior advances and allows further draws. Interest and repayment terms match the Extension Note. Item 3.02 states that units and underlying securities issuable upon any conversion of the notes may not, subject to limited exceptions, be transferable or salable by the payee until completion of the initial business combination and carry registration rights. Exhibits 10.1 and 10.2 are the notes; Exhibit 99.1 is the April 27, 2026 press release on the extension. Close-path versus cash: the $850,000 trust deposit buys three months on Pulse without a shareholder extension vote in this filing and leaves trust cash (V) intact on the stated mechanics. Both notes are sponsor-side claims due only at combination or liquidation, so they do not reduce trust value ahead of a deal. Rights remain structured as one whole right to one-eighth of one Class A ordinary share. The filing does not identify a target, announce a definitive agreement or LOI, describe combination status, quantify remaining trust or shares outstanding, or set out any redemption offer tied to this extension.
