Press Release Announcing Receipt of the Nasdaq Minimum Bid Price Deficiency Letter
On May 29, 2026, Zhengye Biotechnology Holding Limited (the “Company”) received a notice from the Listings Qualifications Department (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that the minimum bid price per share of its Class A ordinary shares was below $1.00 for a period of 30 consecutive business days and that the Company did not meet the minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Rule”). The Nasdaq notification letter does not result in the immediate delisting of the Company’s Class A ordinary shares, and the shares will continue to trade uninterrupted under the symbol “ZYBT.”
Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has a compliance period of one hundred eighty (180) calendar days, or until November 25, 2026 (the “Compliance Period”), to regain compliance with Nasdaq’s minimum bid price requirement. If at any time during the Compliance Period, the closing bid price per share of the Company’s Class A ordinary shares is at least $1.00 for a minimum of ten (10) consecutive business days, Nasdaq will provide the Company a written confirmation of compliance and the matter will be closed.
In the event the Company does not regain compliance by November 25, 2026, the Company may be eligible for an additional 180 calendar day grace period. To qualify, the Company will be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for the Nasdaq Capital Market, with the exception of the bid price requirement, and will need to provide written notice of its intention to cure the deficiency during the second compliance period, including by effecting a reverse stock split, if necessary. If the Company chooses to implement a reverse stock split, it must complete the split no later than ten (10) business days prior to November 25, 2026, or the expiration of the second compliance period if granted.
This information is being provided solely to comply with NASDAQ Listing Rules requiring public announcement of the Company’s receipt of the letter from NASDAQ.
On June 4, 2026, the Company issued a press release entitled “Zhengye Biotechnology Holding Limited Receives Nasdaq Notification Regarding Minimum Bid Price Deficiency.” A copy of the press release is furnished herewith as Exhibit 99.1 and is incorporated herein by reference.

Exhibit 99.1
Zhengye Biotechnology Holding Limited Receives Nasdaq Notification Regarding Minimum Bid Price Deficiency
Jilin, China, June 4, 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.
