**Xenetic Biosciences Reports First Quarter 2026 Financial Results and Highlights**

**Continued Advancement of DNase Oncology Platform**

 

*Advancements across investigator-initiated studies, translational research and*

*manufacturing activities supporting future clinical development*

 

*<br> Strengthened financial profile with continued royalty revenue growth*

<br> *Ended first quarter 2026 with approximately $7.3 million in cash while continuing*

*evaluation of strategic alternatives to maximize shareholder value*

 

**FRAMINGHAM, MA – (May 13, 2026)** – 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 reported its financial results for the quarter ended March 31, 2026 and provided a corporate update on the advancement of its innovative DNase oncology platform.

**Recent Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;· Generated robust translational data supporting the DNase I platform across
multiple oncology settings

&nbsp;&nbsp;&nbsp;&nbsp;· Completed process improvement and analytical development activities supporting
future clinical manufacturing readiness

&nbsp;&nbsp;&nbsp;&nbsp;· Established translational and biomarker insights intended to help inform
and de-risk future clinical trial design

&nbsp;&nbsp;&nbsp;&nbsp;· Collaboration partner received approval from Israeli Ministry of Health to
conduct investigator-initiated exploratory study of DNase I in combination with anti-CD19 CAR T cells in large B-cell lymphoma

"We entered 2026 with a clear focus on advancing the translational, manufacturing and clinical foundation of our DNase I platform while maintaining financial discipline," said James Parslow, Interim Chief Executive Officer and Chief Financial Officer of Xenetic. "During the quarter, we achieved important progress across investigator-initiated studies, translational research and manufacturing readiness activities. We believe the growing body of translational evidence supporting NET-targeting approaches, combined with the expanding understanding of NETs as drivers of tumor progression, immune suppression and therapy resistance, continues to strengthen the potential opportunity for DNase I as a differentiated adjunctive immuno-oncology therapy across multiple cancer settings."

Xenetic's proprietary DNase technology is being developed as a potential adjunctive therapeutic approach designed to improve the effectiveness of existing cancer treatments, including immunotherapies, through the targeting of NETs, which are increasingly recognized as key drivers of immune suppression and therapeutic resistance within the tumor microenvironment.

**Summary of Financial Results for First Quarter 2026**

<br> Royalty revenue for the three months ended March 31, 2026 increased approximately 36% to approximately $0.8 million, compared to approximately $0.6 million for the comparable prior year period, primarily driven by increased royalty payments recognized under the Company's sublicense agreement with Takeda Pharmaceuticals Co. Ltd.

Research and development expenses for the three months ended March 31, 2026 decreased approximately 25% to approximately $0.7 million from approximately $0.9 million for the comparable prior year period, primarily due to lower preclinical and exploratory study costs, partially offset by increased manufacturing development efforts supporting the Company's DNase I program.

General and administrative expenses for the three months ended March 31, 2026 decreased by approximately 1.4%, to approximately $0.6 million from approximately $0.7 million in the comparable quarter in 2025. The decrease was primarily due to a decrease in personnel costs and share-based expenses related to our interim Chief Executive Officer substantially offset by an increase in legal expenses related to our strategic review process during the first quarter of 2026 compared to the same period in 2025.

Net loss for the quarter ended March 31, 2026 decreased approximately 49% to approximately $0.5 million, compared to approximately $0.9 million for the same period in 2025.

The Company ended the first quarter of 2026 with approximately $7.3 million in cash and cash equivalents, compared to approximately $7.9 million as of December 31, 2025.
