VALION BIO REPORTS FIRST QUARTER 2026 FINANCIAL RESULTS

First Reporting Quarter as Valion Bio Marked by Continued Advancement of the Entolimod Platform, Broader Government Engagement, and Continued Integration of Velocity Bioworks

Conference Call to be Held Today at 1:30 PM PT / 4:30 PM ET

SAN ANTONIO  , May 14, 2026 /PRNewswire/ -- Valion Bio, Inc. (formerly Tivic Health Systems, Inc.) (Nasdaq: VBIO), a clinical-stage immunotherapeutics company, today reported financial results for the three months ended March 31, 2026 — the company's first full reporting quarter under its new corporate identity — and provided a business update on the continued advancement of its Entolimod platform, ongoing engagement with U.S. government agencies, and continued integration of wholly owned manufacturing subsidiary Velocity Bioworks.

First Quarter 2026 Highlights and Subsequent Events

• Completed corporate transformation, including the change of the company's legal name from Tivic Health Systems, Inc. to Valion Bio, Inc. and the change of the company's Nasdaq listing symbol from TIVC to VBIO, consolidating the company's identity as a focused clinical-stage immunotherapeutics platform.
   
• Advanced engagement with U.S. government agencies, including BARDA, the National Institute of Allergy and Infectious Diseases (NIAID), and the Department of War, regarding the development, procurement, and stockpiling of Entolimod as a medical countermeasure for Acute Radiation Syndrome (ARS).
   
• Continued integration of Velocity Bioworks, the company's wholly owned contract development and manufacturing organization (CDMO) subsidiary acquired in December 2025, with operational workstreams advancing across both internal pipeline manufacturing support and third-party CDMO business development.
   
• Reinforced regulatory pathway for Entolimod under the FDA's Animal Rule, supported by the program's Fast Track and Orphan Drug designations and the previously demonstrated 200-fold manufacturing scale-up at 50-liter fermentation, equivalent to approximately 1.3 million human doses.
   
• Continued advancement of Entolasta, the company's next-generation TLR5 agonist, designed to support broader therapeutic applications including oncology supportive care, longevity, and immunosenescence.
   
• Maintained domestic biologics manufacturing footprint through Velocity Bioworks' San Antonio, Texas operations, addressing both the company's internal pipeline manufacturing requirements and a structurally underserved Phase I and Phase II domestic biologics manufacturing market.

The first quarter of 2026 was, by design, a quarter of execution rather than announcement: the first full quarter operating with Velocity Bioworks integrated, the first quarter following the previously demonstrated 200-fold manufacturing scale-up, and the first quarter under the Valion Bio identity. The transition follows the divestiture and discontinuation of the legacy consumer bioelectronics business completed in 2025 and consolidates the company's focus on the development and potential commercialization of its TLR5 platform.

"The transition to Valion Bio is more than a change of name and ticker. It reflects the institutional identity we have built — a clinical-stage immunotherapeutics company anchored by a differentiated TLR5 platform, an in-house biologics manufacturing capability through Velocity Bioworks, and increasing visibility within the federal agencies responsible for national medical countermeasure preparedness," said Michael K. Handley, Chief Executive Officer of Valion Bio. "Each of those pillars advanced through the first quarter, and we believe the company enters the balance of 2026 with sharper focus, deeper engagement, and broader optionality than at any point in our history."

Government engagement broadened across multiple agencies during the quarter. Building on the previously disclosed non-clinical evaluation agreement with NIAID, Valion Bio further advanced Entolimod toward potential procurement and stockpiling under the FDA's Animal Rule pathway. Engagement with BARDA, the Department of War, and additional federal stakeholders progressed in scope and depth over the same period. Entolimod's profile — dual gastrointestinal and hematopoietic protection, repeat-dose tolerability supported by a deletion-variant design that reduces immunogenicity, Fast Track and Orphan Drug designations, and a domestic manufacturing footprint — represents a meaningful point of differentiation from currently fielded countermeasures, and one that aligns with both Strategic National Stockpile modernization priorities and allied-government preparedness initiatives.

Integration of Velocity Bioworks advanced on multiple fronts during the quarter. The San Antonio facility continued to support internal Entolimod manufacturing capability while active business development discussions with third-party biotech sponsors progressed in parallel. Velocity addresses a structurally underserved domestic Phase I and Phase II biologics manufacturing market and is expected to function both as a cost and timeline accelerant for Valion Bio's internal pipeline and, increasingly, as a stand-alone source of revenue and operating leverage.

"Beyond Entolimod's role in radiation defense, the most significant commercial opportunity in front of us is oncology supportive care," Mr. Handley continued. "Neutropenia and related conditions affect a meaningful proportion of patients undergoing chemotherapy and radiation therapy, and the mechanistic profile of Entolimod — together with the broader applicability of our second-generation molecule, Entolasta — positions us to address that market with a differentiated entry. Velocity Bioworks accelerates our path on both fronts: it compresses our internal development timelines, structurally lowers our manufacturing cost base, and creates a stand-alone CDMO revenue stream serving the broader biotech industry. The first quarter was a quarter of execution, and we are building."

Pipeline development advanced across both molecules during the quarter. Entolimod continued progressing toward potential approval under the FDA's Animal Rule, with regulatory and clinical development workstreams positioned to support both medical countermeasure and oncology supportive care applications, including neutropenia. Entolasta, the company's next-generation TLR5 agonist, continued to advance as a strategic platform extension — engineered to support broader therapeutic applications including longevity, immunosenescence, and additional oncology supportive care indications, areas where the underlying TLR5 mechanism is mechanistically suited and the addressable markets are substantial.

Financial Results for the Three Months Ended March 31, 2026

Operating expenses for the three months ended March 31, 2026 were $5.6 million, compared with $1.4 million for the three months ended March 31, 2025. The year-over-year change reflects the inclusion of Velocity Bioworks operating costs following the December 2025 acquisition, continued advancement of the Entolimod regulatory and development program, and one-time costs associated with the corporate rebrand and Nasdaq symbol change.

Net loss for the three months ended March 31, 2026 was $6.2 million, or $2.23 per share, compared with a net loss of $1.5 million, or $2.52 per share, for the three months ended March 31, 2025. Cash and cash equivalents at March 31, 2026 totaled $7.2 million, compared with $12.6 million at December 31, 2025. The company continues to evaluate capital alternatives to support continued execution against pipeline, regulatory, and manufacturing milestones.

About Entolimod for Acute Radiation Syndrome

Entolimod (CBLB502) is a recombinant deletion variant of Salmonella FliC flagellin engineered to activate TLR5 selectively. Upon engagement, Entolimod triggers NF-κB-dependent signaling to stimulate G-CSF, PI3K, and IL-6 production, promote multi-tissue cytoprotection, and inhibit apoptosis in radiosensitive hematopoietic and gastrointestinal tissues. The compound has demonstrated survival benefit as both a radioprotectant and a radiomitigant in controlled non-human primate studies under the FDA's Animal Rule.
