YS Biopharma Receives Additional 180 Day Extension by Nasdaq to Regain Compliance with Minimum Bid Price Rule

GAITHERSBURG, Md., April 29, 2024 /PRNewswire/ -- YS Biopharma Co., Ltd. (Nasdaq: YS) (“YS 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 it received an extension of 180 calendar days (the “Extension Notice”) from The Nasdaq Stock Market LLC (“Nasdaq”) to regain compliance with the Nasdaq’s minimum $1.00 bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on The Nasdaq Capital Market (the “Bid Price Requirement”), following the expiration of the initial 180 calendar days period to regain compliance on April 22, 2024.

As previously announced, the Company received a written notification from Nasdaq dated October 24, 2023, indicating that because the closing bid price of the Company’s ordinary shares for the last 31 consecutive business days was below $1.00 per share, the Company was not in compliance with the Bid Price Requirement, and Nasdaq granted the Company a period of 180 calendar days, or until April 22, 2024, to regain compliance with the Bid Price Requirement.

As of the date hereof, the Company has not regained compliance with the Bid Price Requirement. That being said, pursuant to the Extension Notice, the Company is eligible for an additional 180 calendar day period, or until October 21, 2024, to regain compliance with the Bid Price Requirement. To regain compliance, the Company’s ordinary shares must have a closing bid price of at least US$1.00 per share for a minimum of 10 consecutive business days, at which point the matter will be closed. In the event that the compliance cannot be demonstrated by October 25, 2024, the staff of Nasdaq will provide written notification that the Company’s securities will be delisted.

The Company intends to monitor the closing bid price of its ordinary shares between now and October 21, 2024 and is considering its options in order to regain compliance with the Bid Price Requirement. The Extension Notice does not affect the Company’s business operations, its U.S. Securities and Exchange Commission reporting requirements, or its contractual obligations.
