(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, today announced its financial results for the first quarter ended March 31, 2025 and provided highlights on its clinical programs. “I continue to be encouraged by the progress across our CAB platform, particularly with our Phase 1 dose-escalation study evaluating our dual conditionally-binding EpCAM and CD3 bispecific T-cell engager,” said Jay M. Short, Ph.D., Chairman, Chief Executive Officer and co-founder of BioAtla, Inc. “It is also gratifying to observe the maturing Phase 2 datasets, demonstrating exceptional overall survival among patients treated with Mec-V and potent anti-tumor activity observed in refractory HPV+ head and neck cancer patients treated with Oz-V.” Key Developments, Operational Updates and Upcoming MilestonesPrograms Advancing Internally Phase 1/2 dose-escalation for conditionally-binding BA3182 (CAB-EpCAM x CAB-CD3 TCE) (NCT05808634) in heavily pretreated patients with unresectable or metastatic adenocarcinoma Phase 1 dose escalation ongoing and on track for data readout mid-2025Dosed first three patients at the 300 microgram treatment doseCohort expansion data readout anticipated 1H 2026 Phase 2 trial of mecbotamab vedotin (Mec-V), CAB-AXL-ADC (NCT04681131) in mKRAS NSCLC (median of 3 prior lines of treatment) Promising anti-tumor activity among 17 patients whose tumors express mKRAS mutations with multiple confirmed responses at the 1.8 mg/kg Q2W dosing regimenOngoing exceptional overall survival (now at 67%, 1-year landmark survival) and encouraging clinical benefit / risk profileTwo-year landmark survival of 59% in mKRAS non-small cell lung cancer (NSCLC); Previous studies have reported 2-year landmark survival less than 20% among patients treated with standard of care agentsContinuing to observe a high correlation of AXL and mKRAS expression; study follow-up ongoingCurrently positioning asset for a future pivotal trial with Phase 2 clinical data readout in 1H26 Phase 2 Programs Planned for Advancement Through Corporate Partnerships Phase 2 Trial of ozuriftamab vedotin (Oz-V), CAB-ROR2-ADC (NCT05271604) in treatment-refractory SCCHN (median of 3 prior lines of treatment) Oz-V monotherapy continues to demonstrate compelling antitumor activity among patients with 2L+ SCCHN at the 1.8 mg/kg Q2W dosing regimen; overall response rate (ORR), duration of response (DOR), progression-free survival (PFS), and OS data capture ongoingOf note, Oz-V demonstrated meaningful antitumor activity in HPV+ SCCHN, which represents a sizable and growing patient population and one that is poorly served by EGFR inhibitors and other standard of care regimens. Disease control rate 100%; ORR 45% (5/11); 27% (3/11) confirmed, continuing follow-upOther studies using standard of care agents have reported ORR of 0% to 3.4% among HPV+ SCCHN patients.

First Quarter 2025 Financial Results Research and development (R&D) expenses were $12.4 million for the quarter ended March 31, 2025 compared to $18.9 million for the same quarter in 2024. The decrease of $6.5 million was primarily due to lower clinical development expenses in 2025 for our Phase 2 trials for mecbotamab vedotin, ozuriftamab vedotin and evalstotug as we complete trials for certain indications. These decreases were partially offset by a $0.5M charge related to our workforce reduction announced in March 2025. We expect our R&D expenses to continue to decrease for the remainder of 2025 due to our recent restructuring and as we complete Phase 2 trials for several indications and focus our ongoing development on our prioritized programs. General and administrative (G&A) expenses were $5.3 million for the quarter ended March 31, 2025 compared to $5.6 million for the same quarter in 2024. The $0.3 million decrease was primarily due to lower stock based compensation and lower D&O insurance premiums, offset by a $0.1M charge related to our workforce reduction announced in March 2025. Net loss for the quarter ended March 31, 2025 was $15.3 million compared to a net loss of $23.2 million for the same quarter in 2024. Net cash used in operating activities for the quarter ended March 31, 2025 was $16.3 million compared to net cash used in operating activities of $30.8 million for the same period in 2024. Cash used for the quarter ended March 31, 2025 was $16.7 million. Cash and cash equivalents as of March 31, 2025 were $32.4 million, compared to $49.0 million as of December 31, 2024. We expect that cost reductions to be subsequently realized from our realignment of resources and focus on our two internal priority programs will provide the Company with sufficient runway to fund operations and achieve key clinical readouts in the first half of 2026, excluding funds from potential new partnerships.

About CAB-EpCAM x CAB-CD3 Bispecific T-cell Engager Antibody BioAtla is developing BA3182 as a potential anticancer therapy for patients with advanced adenocarcinoma. BA3182 is a (CAB) EpCAM x (CAB) CD3 bispecific T cell engager antibody that contains two binding sites for EpCAM and two binding sites for CD3ε. The binding sites for EpCAM and CD3ε have been designed to bind their respective targets specifically and reversibly under the conditions found in the TME and to have reduced binding outside of the TME. The CAB selective binding to both the CAB EpCAM and CAB CD3ε arms are required to activate the T cell engagement against the tumor, thus enabling the combined selectivity of each CAB binding arm in the bispecific antibody. BioAtla continues to advance the ongoing Phase 1 study to evaluate the safety, pharmacokinetics, and efficacy of BA3182 in advanced adenocarcinoma patients. About Mecbotamab VedotinMecbotamab vedotin (Mec-V), CAB-AXL-ADC, is a conditionally and reversibly active antibody drug conjugate targeting the receptor tyrosine kinase AXL. This Phase 2 stage clinical asset is targeting multiple solid tumor indications, including mKRAS NSCLC patients who have previously progressed on PD-1/L1, epidermal growth factor receptor or ALK inhibitor therapies. About Ozuriftamab VedotinOzuriftamab vedotin (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, triple-negative breast cancer and melanoma. Overexpression of ROR2, a noncanonical wnt5A signaling receptor, forms a cancer axis that is associated with poor prognosis and resistance to chemo- and immunotherapies. This Phase 2 stage clinical asset is targeting multiple solid tumor indications, including initially the treatment of SCCHN patients who have previously progressed on PD-1/L1 therapies with or without platinum chemotherapy. The FDA granted Fast Track Designation to ozuriftamab vedotin for the treatment of patients with recurrent or metastatic SCCHN. About Evalstotug Evalstotug, is a CAB anti-CTLA-4 antibody that is being developed as an immuno-oncology agent with the goal of delivering efficacy at least comparable to the approved anti-CTLA-4 antibodies, but with lower toxicities due to the CAB's tumor microenvironment (TME)-restricted activity. This is anticipated to enable safer anti-CTLA-4 antibody combination therapies, such as with anti-PD-1 antibody checkpoint inhibitors, and potentially broaden the patient population tolerant to combination therapy and deliver greater efficacy. Like our other CAB candidates, this Phase 2 clinical asset is designed to be conditionally and reversibly active in the TME. Evalstotug is being developed as a potential therapeutic for multiple solid tumor indications that are known to be responsive to CTLA-4 treatment in combination with a PD-1 blocking agent. About BioAtla®, Inc. BioAtla is a global clinical-stage biotechnology company with operations in San Diego, California, and in Beijing, China through its contractual relationship with BioDuro-Sundia, a provider of preclinical development services.
