SAB Biotherapeutics (SABS) is a clinical-stage biopharmaceutical company focused on developing human polyclonal antibody therapies. As such, it does not sell directly to individuals or typically to other companies as finished commercial products at this stage. Its primary "customers" or sources of revenue come from government contracts and strategic collaborations.

The company's major customer/funding source has been:

• The U.S. Government: Specifically, agencies such as the Biomedical Advanced Research and Development Authority (BARDA), which is part of the U.S. Department of Health and Human Services (HHS). BARDA has provided significant funding and contracts to SAB Biotherapeutics for the development of its programs, particularly during the COVID-19 pandemic for therapies like SAB-185, and for other infectious disease preparedness initiatives.

While SAB Biotherapeutics engages in various collaborations and partnerships with other biotechnology and pharmaceutical companies for research, development, or platform utilization, these are generally not structured as traditional "customer" relationships where a company purchases commercial products from SABS. As a clinical-stage company, its business model primarily involves advancing its drug candidates through trials with the support of government funding or strategic development partners, prior to potential future commercialization or licensing agreements.

The key risks to SAB Biotherapeutics (SABS) are primarily associated with its nature as a clinical-stage biopharmaceutical company, revolving around the development and commercialization of its product candidates.

1. Clinical Trial Failure and Regulatory Approval Risk: As a company with pipeline products undergoing clinical development, SAB Biotherapeutics faces substantial risk that its product candidates, including its lead candidate SAB-142 for autoimmune Type 1 Diabetes, may fail to demonstrate efficacy or safety in clinical trials, or may not receive the necessary regulatory approvals. Unfavorable results from Phase I, II, and III studies could lead to significant stock volatility and downward pressure. The high expectations surrounding the company's stock are largely predicated on successful Phase 2b data for SAB-142.
2. Funding and Liquidity Risk: SAB Biotherapeutics is expected to continue incurring significant operating losses due to high research and development, preclinical testing, and clinical development expenses. While a recent oversubscribed private placement of $175 million is anticipated to extend its cash runway into mid-2028 and fund the pivotal Phase 2b SAFEGUARD study for SAB-142, the company does not yet generate revenue, with analysts forecasting $0 revenue for 2025, 2026, and 2027. Further capital will likely be required for continued development, manufacturing, and potential commercialization, and there is no guarantee that such financing will be available on favorable terms, or at all, which could lead to dilution for existing shareholders or hinder product development.
3. Dependence on a Limited Product Pipeline: The company's prospects are heavily reliant on the success of its lead product candidate, SAB-142. While the company has other discovery programs, a significant portion of investor focus and recent financing is directed towards SAB-142. A failure of SAB-142 in clinical trials or to gain regulatory approval would severely impact the company's valuation and future viability, as the pipeline beyond this lead candidate is less advanced or publicly emphasized.

SAB Biotherapeutics (SABS) is focused on developing immunotherapies, with its primary product candidate, SAB-142, targeting Type 1 Diabetes (T1D). The addressable market for T1D therapeutics is substantial and global.

• The global market for Type 1 Diabetes therapeutics is estimated at $16.97 billion in 2025, with projections indicating growth to $26.22 billion by 2032. SAB-142 is being developed as a disease-modifying immunotherapy to delay the onset and progression of T1D, specifically aiming to preserve beta-cell function in newly diagnosed patients aged 5-40.
• SAB Biotherapeutics also has SAB-176 in its pipeline, a fully-human polyclonal antibody therapeutic candidate for the treatment or prevention of severe influenza. While this product is aimed at key global markets, including the U.S., EU4 (Germany, France, Italy, and Spain), the UK, and Japan, with anticipated market entry playing a significant role in improving treatment options for severe flu cases, specific market size figures in U.S. dollars were not identified in the provided information.

SAB Biotherapeutics (SABS) is a clinical-stage biopharmaceutical company with expected drivers of future revenue growth over the next 2-3 years primarily centered on the advancement and commercialization of its novel immunotherapy platform and lead therapeutic candidates.

1. Advancement and Commercialization of Lead Candidate (SAB-142) for Type 1 Diabetes (T1D): SAB-142 is a novel, potentially disease-modifying human anti-thymocyte immunoglobulin (hIgG) therapy aimed at delaying the onset or progression of Type 1 Diabetes (T1D). The company has reported positive Phase 1 topline data for SAB-142, with the third cohort fully enrolled and dosed without observed serum sickness. Furthermore, SAB Biotherapeutics is initiating its Phase 2b SAFEGUARD study for SAB-142 in new-onset Stage 3 autoimmune T1D patients. Successful progression through clinical trials, regulatory approvals, and eventual market launch of SAB-142 would be a significant revenue driver.
2. Broader Application and Commercialization of the DiversitAb™ Platform: The company's proprietary DiversitAb™ platform utilizes transchromosomic (Tc) bovine™ herds to produce highly potent, targeted, fully human polyclonal antibody therapeutics. This versatile and scalable platform is applicable to a wide range of serious human diseases, including immune system disorders, cancer, and infectious diseases. Research has shown the platform's capability to generate functional fully-human anti-idiotype polyclonal antibodies for autoimmune diseases. Expanding the application of this platform beyond T1D into other therapeutic areas, through either new internal drug candidates or collaborations, represents a substantial growth opportunity.
3. Strategic Partnerships and Collaborations: SAB Biotherapeutics engages in collaborations with global pharmaceutical companies and has received funding from the U.S. government for its rapid response programs. The company has an exclusive manufacturing services agreement with Emergent BioSolutions, which also includes the opportunity for Emergent to utilize the DiversitAb™ platform for future undisclosed programs. New or expanded partnerships for drug development, manufacturing, or commercialization of its pipeline assets or platform technology could generate revenue through upfront payments, milestone achievements, and royalties.
