Company Announcements

BEIJING , Sept. 22, 2025 /PRNewswire/ -- LakeShore Biopharma Co., Ltd (Nasdaq: LSB) ("LakeShore Biopharma" or the "Company"), a global biopharmaceutical company dedicated to discovering, developing, manufacturing, and delivering new generations of vaccines and therapeutic biologics for infectious diseases and cancer, today announced that effective with the opening of business today, September 22, 2025, the Company's ordinary shares and warrants have been suspended from trading on The Nasdaq Capital Market ("Nasdaq").

On the same day, the Company's ordinary shares and warrants are expected to commence trading on the OTC Pink Open Market ("OTC Market") under the symbols "LSBCF" and "LSBWF", respectively.

This action follows the receipt of a delisting determination letter from Nasdaq on September 11, 2025, as previously disclosed by the Company on September 12, 2025. Nasdaq's determination was based on the Company's non-compliance with the minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) and its ineligibility for a compliance period under Nasdaq Listing Rule 5810(c)(3)(A)(iv) due to a prior reverse stock split.

The transition to the OTC Market does not change the Company's business operations. The Company remains a reporting company with the U.S. Securities and Exchange Commission and is committed to maintaining transparency with its shareholders and the public.
