On September 23, 2025, Estrella Immunopharma, Inc. (the "Company") received two letters from the Listing Qualifications Department of The Nasdaq Stock Market LLC ("Nasdaq") indicating that the Company has regained compliance with certain of Nasdaq's continued listing requirements.

The first letter confirmed the Company has regained compliance with the minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2). As previously disclosed in a Current Report on Form 8-K filed with the Securities and Exchange Commission on May 2, 2025, the Company was notified by Nasdaq on April 30, 2025, that it was not in compliance with this requirement. The letter from Nasdaq states that for the 10 consecutive business days from September 9, 2025, through September 22, 2025, the closing bid price of the Company's common stock was $1.00 per share or greater. Accordingly, Nasdaq considers this matter closed.

The second letter confirmed the Company has regained compliance with the minimum market value of listed securities requirement under Nasdaq Listing Rule 5550(b)(2). As previously disclosed in a Current Report on Form 8-K filed with the Securities and Exchange Commission on August 7, 2025, the Company was notified by Nasdaq on August 1, 2025, that it was not in compliance with this requirement. The letter from Nasdaq states that for the 17 consecutive business days from August 28, 2025, through September 22, 2025, the Company's market value of listed securities was $35,000,000 or greater. Accordingly, Nasdaq considers this matter closed
