EX-99.A

Exhibit A

Shareholders Led by Yi Zhang Announce Successful Results of Removal of Directors and Election of New Directors of YS Biopharma Co., Ltd.

(New York – 16 February, 2024) Yi Zhang and shareholders representing over 59.2% of the outstanding shares of YS Biopharma Co., Ltd. (the “Company” or “YS”) (NASDAQ: YS) (the “Convening Shareholders”) today announced the successful approval of all resolutions at the YS Extraordinary General Meeting of Shareholders (“EGM”) held today. 62,132,308 shares out of 93,058,197 total outstanding shares of YS voted in the EGM, which represents 66.8% of all outstanding shares. Before the EGM, individuals purporting to be representatives of the Company arrived at the offices where the EGM was to be conducted, but they indicated that they intended to disrupt the business for which the EGM was convened by the Convening Shareholders, so they were not permitted to enter the premises where the EGM was noticed to be held.

The resolutions passed by the shareholders at the EGM are as follows:

1. The removal of the following directors from office of the Company: Hui Shao, Bo Tan, Ajit Shetty, Viren Mehta, Shaojing Tong, Rachel Yu, Yuntao Cui, Jin Wang, Henry Chen, Haitao Zhao, Pierson Yue Pan and Chunyuan (Brenda) Wu; and

2. the election of the following seven nominees as directors of the Company: Nan Zhang, Yun (Monica) Zhang, Chi Keung (Peter) Lui, Jing Xia Li, Yi Zhang, Yuan Liu and Jimin Wang.

Details of the number of shares voted in person or by proxy on the resolutions was as follows:

Resolution	For		Against
	Shares Voted	%	Shares Voted	%
1.    The removal of the following directors from office of the Company: Hui Shao, Bo Tan, Ajit Shetty, Viren Mehta, Shaojing Tong, Rachel Yu, Yuntao Cui, Jin Wang, Henry Chen, Haitao Zhao, Pierson Yue Pan and Chunyuan (Brenda) Wu.	55,123,743	88.7%	7,008,565	11.3%
2.    The election of the following seven nominees as directors of the Company: Nan Zhang, Yun (Monica) Zhang, Chi Keung (Peter) Lui, Jing Xia Li, Yi Zhang, Yuan Liu and Jimin Wang.	55,123,743	88.7%	7,008,565	11.3%

There were no abstentions and no “withhold” votes. 

Yi Zhang thanks his fellow shareholders for their support in achieving this positive outcome today. The actions taken reflect an overwhelming shareholder repudiation of the prior board of directors of the Company (the “Board”) and the total disregard for shareholder perspectives shown by the prior Board and management team. Given the result of the vote, Yi Zhang is confident that YS will now be able to focus its full efforts on executing its business strategy and preserving and growing long-term value for all shareholders.

The full text of each resolution is contained in the notice of general meeting set out in the Circular, a copy of which is available here:  https://www.sec.gov/Archives/edgar/data/1946399/000110465924024545/tm246234d1_ex99-a.htm

Immediately following the successful conclusion of the EGM, the new board of directors of the Company voted [unanimously] to effect the following resolutions (among others):

1. the appointment of Mr. Yi Zhang as the chairperson of the board with immediate effect;

2. the removal of each of Hui Shao, Bo Tan, Ajit Shetty, Viren T. Mehta, Shaojing Tong and Rachel Yu (collectively, the “Removed Directors”) from all of the relevant committees of the board of the Company including the audit committee, the compensation committee and the nominating and corporate governance committee and from the relevant board and committee (if any) of each subsidiary of the Company with immediate effect;

3. the appointment of each of Jing Xian Li, Chi Keung (Peter) Lui and Yun (Monica) Zhang as a member of the audit committee and Chi Keung (Peter) Lui as the chairperson of the audit committee with immediate effect;
