Jilin, China, June 04, 2026 (GLOBE NEWSWIRE) -- Zhengye Biotechnology Holding Limited (Nasdaq: ZYBT) (the “Company” or “Zhengye”), a veterinary vaccine manufacturer that encompasses research, development, manufacturing, and sales of veterinary vaccines, with a focus on livestock vaccines in China, announced that the Company had received a written notification letter (the “Notification Letter”) from the Nasdaq Stock Market LLC (“Nasdaq”) on May 29, 2026, notifying the Company that it is not in compliance with the minimum bid price requirement set forth in the Nasdaq Listing Rules 5550(a)(2) for continued listing on the Nasdaq.

Nasdaq Listing Rule 5550(a)(2) requires listed securities to maintain a minimum bid price of US$1.00 per share, and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum bid price requirement exists if the deficiency continues for a period of 30 consecutive business days. Based on the closing bid price of the Company’s Class A ordinary shares for the 30 consecutive business days from April 16, 2026 to May 28, 2026, the Company no longer meets the minimum bid price requirement.

The Notification Letter does not impact the Company’s listing on the Nasdaq Capital Market at this time. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has been provided 180 calendar days, or until November 25, 2026, to regain compliance with Nasdaq Listing Rule 5550(a)(2). To regain compliance, the Company’s Class A ordinary shares must have a closing bid price of at least US$1.00 for a minimum of 10 consecutive business days. In the event the Company does not regain compliance by November 25, 2026, the Company may be eligible for additional time to regain compliance or may face delisting.

The Company’s business operations are not affected by the receipt of the Notification Letter. The Company is monitoring the closing bid price of its Class A ordinary shares and may, if appropriate, consider implementing available options, including, but not limited to, implementing a reverse share split of its outstanding Class A ordinary shares, to regain compliance with the minimum bid price requirement under the Nasdaq Listing Rules.
