On May 20, 2026, A SPAC III Acquisition Corp. (the “Company”) received a letter from The Nasdaq Stock Market LLC (“Nasdaq”), which stated that because the stockholders’ equity of the Company reported on its Form 10-Q for the fiscal quarter ended March 31, 2026 was below the minimum of $2,500,000 stockholders’ equity (the “Minimum Stockholders’ Equity Requirement”) required for continued listing pursuant to Nasdaq Listing Rule 5550(b)(1), the Company no longer complies with Nasdaq’s continued listing rules on The Nasdaq Capital Market. In accordance with the Nasdaq listing rules, the Company has 45 calendar days to submit a plan to regain compliance and, if Nasdaq accepts the plan, Nasdaq can grant the Company an extension of up to 180 calendar days from the date of the letter to evidence compliance. The Company is currently working on a compliance plan and plans to submit it to Nasdaq within the specified period. There is no assurance that the Company will be able to regain compliance with the Minimum Shareholders’ Equity Requirement or that its compliance plan will be accepted by Nasdaq.
