| Item 1.01 | Entry into a Material Definitive Agreement. |
On December 30, 2025, BioAtla, Inc. (“the Company” or “BioAtla”) entered into an Investment Agreement (the “Investment Agreement”) with Inversagen AI, LLC, a Delaware limited liability company (“Inversagen AI”), and Alliance International Resources Corp., a Nevada corporation (“AIRC”). Subject to completion of financings by Inversagen AI as set forth in the Investment Agreement, with the initial investment led by AIRC to close by January 30, 2025, the Company agreed to sell common units of its wholly-owned subsidiary, BA 3021 SPV LLC, a Delaware limited liability company (the “SPV”) to Inversagen AI in a private placement over multiple closings. Upon completion of the transaction, Inversagen AI will own an aggregate 35% common unit ownership in the SPV in exchange for an aggregate $40 million. The Company expects to use the gross proceeds received from the sale of the SPV common units to Inversagen AI for general operating expenses and clinical trial expenses to advance ozuriftamab vedotin (“Oz-V”), the Company’s CAB-ROR2-ADC clinical asset, in a Phase 3 Study in 2L+ oropharyngeal squamous cell carcinoma (the “Phase 3 Study”).
Subject to completion of financings by Inversagen AI and customary closing conditions, the transaction is expected to occur over two closings. The first closing is expected to occur before January 30, 2026, in which the Company will receive $5 million for the sale of the SPV’s common units to Inversagen AI that represent 4.375% of the SPV common units (the “Initial Closing”). The second closing aligns with the expected initiation of the Phase 3 Study and is expected to occur no later than March 31, 2025. At the second closing, subject to completion of a financing of at least $35 million, Inversagen AI has agreed to purchase an additional 30.625% of the SPV common units in exchange for $35 million. The Investment Agreement contains representations and warranties, covenants and closing conditions, customary for a transaction of this nature.
On December 30, 2025, BioAtla formed a wholly-owned subsidiary, BA 3021 SPV LLC, a Delaware limited liability company (the “SPV”). Concurrently with the Initial Closing, BioAtla will enter into an exclusive license agreement (the “License Agreement”) with the SPV in which BioAtla will grant to the SPV, an exclusive, worldwide, perpetual and irrevocable license to BioAtla’s intellectual property rights in Oz-V. The License Agreement will grant the SPV the right to develop and commercialize Oz-V for all human uses, other than diseases (in all cases excluding oncology) in humans involving senescent cell elimination therapy.
Inversagen AI, LLC is a new company, with a mission to cure age-related diseases, formed with an initial 50:50 ownership between Inversagen, LLC (a company holding exclusive license to CAB senescence and longevity technologies from the Company) and GATC Health Corp (a company with exclusive rights to senescence AI longevity technologies). Pursuant to the Investment Agreement, an initial investment into Inversagen AI will be led by AIRC. As previously disclosed in the Company’s filings, BioAtla entered into an exclusive license agreement with Inversagen, LLC, as amended in July 2020, in which BioAtla granted Inversagen, LLC an exclusive, worldwide, royalty-bearing license under certain patents and know-how controlled by BioAtla to develop, make, have made, sell, have sold, offer for sale and import CAB-antibodies for the field of diseases associated with aging, outside of cancer.
Inversagen, LLC and Inversagen AI are deemed to be related parties of the Company, as the Company’s Chairman and Chief Executive Officer, Dr. Jay Short, and his spouse serve as managers of Inversagen, LLC and Inversagen AI.
The above descriptions of the Investment Agreement is qualified in its entirety by reference to the full text of the Investment Agreement, a copy of which will be filed as exhibits to the Company’s Annual Report on Form 10-K for the year ending December 31, 2025.

Exhibit 99.1
BioAtla and GATC Health Announce a $40 Million Special Purpose Vehicle (SPV) Transaction to Advance Ozuriftamab Vedotin (Oz-V) into a Registrational Trial for 2L+ Oropharyngeal Squamous Cell Carcinoma (OPSCC)
| • | BioAtla will receive an initial $5 million for general operating and Phase 3 clinical trial expenses to advance Oz-V in 2L+ OPSCC with the remaining $35 million anticipated to close in Q1 2026. |
| • | BioAtla to retain 65% ownership of Oz-V across all solid tumor indications after completion of the SPV transaction. |
| • | BioAtla will lead Phase 3 trial execution for Oz-V in OPSCC through data readout for potential accelerated approval and enrollment anticipated to begin early 2026. |
| • | Oz-V targets ROR2, an important receptor that not only drives tumor progression, but also regulates cellular senescence, which is linked to chronic diseases associated with aging. |
SAN DIEGO, December 31, 2025 – BioAtla, Inc. (Nasdaq: BCAB), a global clinical-stage biotechnology company focused on the development of Conditionally Active Biologic (CAB) antibody therapeutics for the treatment of solid tumors, and GATC Health Corp. (GATC), a tech-bio company leveraging artificial intelligence (AI) to transform drug discovery and development, today announced a SPV transaction to advance ozuriftamab vedotin (Oz-V) (CAB-ROR2-ADC) in a Phase 3 Study in 2L+ oropharyngeal squamous cell carcinoma (OPSCC).
As part of the SPV transaction, BioAtla will receive an initial $5 million for general operating and 2L+ OPSCC clinical trial expenses from Inversagen AI, LLC, a newly formed company with a mission to cure age-related diseases. Inversagen AI, LLC was formed by GATC Health Corp. (a company with exclusive license rights to senescence AI longevity technologies) and Inversagen LLC (a company with exclusive license rights to BioAtla’s CAB senescence and longevity technologies).
The initial closing of the SPV transaction will occur concurrently with the initial closing of Inversagen AI, LLC’s financing and is expected to occur by January 30, 2026, with the remaining $35 million anticipated to close later in Q1 2026 when the Oz-V registrational clinical study is expected to begin, in each case subject to completion of financings by Inversagen AI, LLC and customary closing conditions. Inversagen AI will receive an aggregate 35% ownership stake in Oz-V, while BioAtla will retain 65% ownership across all Oz-V solid tumor indications after completion of the transaction.1 BioAtla and GATC Health also expect to collaborate with Inversagen AI for the research and development of CAB senolytic therapies with BioAtla maintaining rights to the cancer therapeutic applications of these new therapies.
“We are excited to announce this partnership for advancing Oz-V into Phase 3 development for the treatment of patients with OPSCC under this creative, single-asset financing structure which maximizes our equity value for our shareholders,” said Jay M. Short, Ph.D., Chairman, Chief Executive Officer and co-founder of BioAtla, Inc. “As we previously announced, we have a clear registrational path with the potential for accelerated approval in the US and are moving to initiate the Phase 3 pivotal trial, which we anticipate will begin enrollment in early 2026. In addition, we continue to advance discussions with potential partners to expand the opportunity more broadly with Oz-V into HPV-positive solid tumors, including cervical cancer.”

Ian Jenkins, Chief Scientific Officer at GATC Health added, “ROR2 is an attractive therapeutic target as it functions at the crossroads of cancer, senescence, and inflammation. ROR2 not only drives tumor progression, but also regulates cellular senescence to modulate growth arrest, and influences inflammatory responses that together affect tissue homeostasis and aging.”
“This is an important partnership for us as it provides a near-term commercial opportunity in OPSCC, as well as laying the foundation to advance the mission of Inversagen AI to cure age-related diseases,” said Jayson Uffens, Chief Technology Officerat GATC Health. “BioAtla’s CAB platform offers a novel, highly specific approach to senolytic therapy with the potential to overcome major limitations of current strategies that often harm beneficial senescent cells. Enabling the selective removal of inflamed, pathogenic senescent cells positions us at the forefront of advances in the treatment of longevity and age-related disease.”

About Ozuriftamab Vedotin (Oz-V)
Oz-V, CAB-ROR2-ADC, is a conditionally and reversibly active antibody drug conjugate directed against ROR2, a transmembrane receptor tyrosine kinase that is present across many different solid tumors including head and neck, lung, cervical, triple-negative breast cancer, and melanoma. Overexpression of ROR2, a non-canonical wnt5A signaling receptor, forms a cancer axis that is associated with poor prognosis and resistance to chemo- and immunotherapies. This Phase 3 stage clinical asset is targeting the treatment of OPSCC patients who have previously progressed on PD-1/L1 therapies with or without platinum chemotherapy. HPV associated expression of E6 and/or E7 oncoproteins drives cancer progression by upregulating ROR2 expression. As such, there is potential to expand the application of Oz-V more broadly beyond OPSCC to all HPV+ cancers, which represents a market opportunity of over $7 billion worldwide. The FDA granted Fast Track Designation to Oz-V for the treatment of patients with recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN). In addition, the company has secured a partnership with an unnamed commercial manufacturer for commercial supply of Oz-V to support cost-effective development through accelerated approval readout and commercial sales.
The oncology rights to Oz-V were licensed by BioAtla to a newly formed special purpose vehicle (Oz-V SPV) which remains a subsidiary of BioAtla. BioAtla will own 65% of the Oz-V SPV following the completion of the transaction. As a result, Inversagen AI, LLC will own an aggregate 35% of the Oz-V SPV and will share in commercialization-related expenses, as well as any additional development of earlier lines of therapy and / or new indications.
About OPSCC
OPSCC is a subset of squamous cell carcinoma of the head and neck (SCCHN) arising from the squamous cells that line the oropharynx, the middle part of the throat. This anatomic region is located behind the oral cavity and OPSCC typically involves the tonsils, soft palate, pharyngeal walls, and/or the base of the tongue. A striking year-to-year increase in OPSCC is due to the rapidly increasing incidence of HPV infections which currently represents approximately 80% of OPSCC in the United States. The prognosis is currently poor for patients with recurrent/metastatic OPSCC who have previously received standard treatments including surgery, radiation, platinum-based chemotherapy, and PD-1 inhibitor therapy.
About ROR2 and CAB Technology in Senescence
ROR2 is involved in pathways that regulate senescent cell survival and proliferation. Senescent cells resist apoptosis partly due to dysregulated signaling pathways that promote their persistence. ROR2-targeting agents could represent a new class of senolytics by modulating receptor signaling involved in regulating the senescent cell state. Senolytic therapies have the potential to improve tissue function, reduce chronic inflammation, and may extend healthy lifespan.
The Conditionally Active Biologics (CAB) technology is a proprietary technology engineered to bind only in acidic, inflammatory conditions found in diseased microenvironments, but not in normal tissues. By targeting key surface markers like ROR2, a receptor overexpressed in multiple solid tumors (pH5.3-6.7) and recognized for its role in inflamed senescent cells or Senescence Associated Secretory Phenotype (SASP; approximate pH6.5-7.0) regulation, CAB-enabled biologics enhance the precision approach to reduce chronic inflammation and tumor progression, while sparing beneficial cells.
