**Xenetic Biosciences, Inc. Announces Adjournment of 2025 Annual Meeting**

 

*Adjourns 2025 Annual Meeting of Stockholders* 

 

*Urges Stockholders Who Have Not Voted To Get Votes In*

 

**FRAMINGHAM, MA – (December 11, 2025)** – Xenetic Biosciences, Inc. (NASDAQ: XBIO) ("Xenetic" or the "Company"), a biopharmaceutical company focused on advancing innovative immuno-oncology technologies addressing difficult to treat cancers, today announced that its 2025 Annual Meeting of Stockholders (the "Annual Meeting") was convened and adjourned without any business conducted due to lack of the required quorum.

A quorum is necessary to hold the Annual Meeting. There were fewer than a majority of the outstanding shares entitled to vote present, either in person or by proxy, at the Annual Meeting. The Annual Meeting therefore had no quorum and was adjourned to allow additional time to solicit additional proxies on behalf of the Company's board of directors. The Annual Meeting will reconvene at 10:00 a.m. Eastern Time on Thursday, January 8, 2026, and will continue to be held virtually.

Stockholders who have already submitted a proxy or voted do not need to vote again, as proxies and votes previously submitted in respect of the Annual Meeting will remain valid at the reconvened Annual Meeting unless properly revoked. The record date for determining stockholders eligible to vote at the reconvened Annual Meeting remains October 15, 2025.

 **Stockholders as of the October 15, 2025 record date who have not yet voted are encouraged to vote online at www.proxyvote.com or by telephone at 1-800-690-6903. Please vote by 11:59 p.m. Eastern Time on January 7, 2026.**

If you hold your shares of the Company's common stock in an account at a brokerage firm, bank, dealer or other similar organization, you may be subject to an earlier voting deadline and you should carefully review any materials received from the organization holding those shares regarding how to vote to ensure your vote is counted.

A copy of the Company's definitive proxy statement for the Annual Meeting is available to stockholders on www.proxyvote.com and on the Company's website at www.xeneticbio.com.

Xenetic stockholders as of the close of business on the October 15, 2025 record date for the Annual Meeting, or their legal proxy holders, will be able to attend the reconvened Annual Meeting by visiting http://www.virtualshareholdermeeting.com/XBIO2025.

**Stockholder Questions**

If you have any questions or require any assistance in voting your shares, please call Okapi Partners LLC at 877-629-6355.

**Important Information**

This press release may be deemed to be solicitation material in respect of the Annual Meeting to be reconvened and held on Thursday, January 8, 2026. In connection with the Annual Meeting, the Company filed a definitive proxy statement with the Securities and Exchange Commission ("SEC") on October 31, 2025. BEFORE MAKING ANY VOTING DECISION, THE COMPANY URGES ITS STOCKHOLDERS TO READ THE PROXY STATEMENT AND ANY OTHER RELEVANT DOCUMENTS FILED WITH THE SEC BECAUSE THEY CONTAIN IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING. The definitive proxy statement was sent or made available to stockholders entitled to vote at the Annual Meeting on or about October 31, 2025. No changes have been made to the proposals to be voted on by stockholders at the Annual Meeting.
