ALT5 Sigma Corporation (the “Company” or “ALT5”) (NASDAQ: ALTS)(FRA: 5AR1) today announced that it received a notification letter (the “Letter”) from The Nasdaq Stock Market LLC (“Nasdaq”), indicating that it has regained compliance with the periodic filing requirements of The Nasdaq Stock Market under Listing Rule 5250(c)(1). As a result, Nasdaq has closed the matter, and the Company remains in good standing with respect to its Nasdaq filing listing requirements.

“We are pleased that this matter has been resolved and that the Company is once again back in compliance regarding its Financials late filing delinquency as per Nasdaq’s listing standards,” said Tony Isaac, President and CEO. “This filing represents our commitment to maintaining the highest standards of corporate governance and transparency. We take our regulatory obligations seriously, and we’re pleased to have completed this important milestone while delivering strong operational results for our stockholders.”

On November 19, 2025, the Company was notified by Nasdaq staff that it was not in compliance with the Rule due to the delayed filing of its periodic report. Following the January 12, 2026 filing of its Form 10-Q for the period ending September 27, 2025, Nasdaq staff determined that the Company now complies with the Rule again.
