Xilio moved its common stock from the Nasdaq Global Select Market to the Nasdaq Capital Market after missing the $1.00 minimum bid price. The move does not cure the bid price problem, and the company's March annual report carried a going-concern warning.
Nasdaq approved the transfer from the Global Select Market effective October 6, 2025. Xilio now has until March 30, 2026 to regain compliance with the minimum bid price rule.
Nasdaq says Xilio reported stockholders' equity of $7,069,000 at June 30, 2025, below the $10.0 million minimum for the Global Select Market. The company has until October 6, 2025 to submit a plan, and it remains out of compliance with the $1.00 minimum bid price rule.
Latest balance sheet, Jun 30, 2026 (10-Q): cash and equivalents $136.0 million.
