Calisa Acquisition Corp

Going Concern Consideration

As of October 23, 2025, the closing date of the IPO, the Company had $658,410 in its operating bank account, and working capital of $579,651. Further, the Company has incurred and expects to continue to incur significant costs in pursuit of its financing and acquisition plans in pursuit of a Business Combination.

In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” management has determined that these conditions raise substantial doubt about the Company’s ability to continue as a going concern. In addition, if the Company is unable to complete a Business Combination within the Combination Period, the Company’s board of directors would proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company. There is no assurance that the Company’s plans to consummate a Business Combination will be successful within the Combination Period. As a result, management has determined that such additional condition also raise substantial doubt about the Company’s ability to continue as a going concern. The financial statement does not include any adjustments that might result from the outcome of this uncertainty.
