Nature of Business | ## (1) Nature of Business SAB Biotherapeutics, Inc., a Delaware corporation (“SAB” or “SAB Biotherapeutics”, and together with its subsidiaries, the “Company”), is a clinical-stage biopharmaceutical company focused on the development of human polyclonal immunotherapeutic antibodies, or human immunoglobulins (“hIgG”), to address immune system disorders and infectious diseases. The Company’s antibodies are both target-specific and polyclonal, meaning they are comprised of multiple hIgGs and can bind to multiple sites on specific immunogens, making them ideally suited to address the complexities associated with many immune-mediated disorders. The Company’s lead candidate, SAB-142 is a human anti-thymocyte globulin (“ATG”) focused on preventing or delaying the progression of type 1 diabetes (“T1D”). Australian Research and Development Tax Credit In June 2023, the Company formed a new subsidiary in Australia, SAB BIO PTY LTD, a proprietary limited company (“SAB Australia”), primarily to conduct preclinical and clinical activities for product candidates. SAB Australia’s research and development activities qualify for the Australian government’s tax credit program, which provides a 48.5% credit for qualifying research and development expenses. Liquidity As of March 31, 2026, the Company had an accumulated deficit of $129.8 million. The Company anticipates that it will continue to generate losses for the foreseeable future and expects the losses to increase as the Company continues the development of, or seeks regulatory approvals for product candidates, and begins commercialization of products. As a result, the Company will require additional capital to fund operations in order to support long-term plans. Based on the Company’s current level of operating expenses, existing resources will be sufficient to cover operating cash needs through at least the twelve months following the date of this report. In the future, the Company may seek additional funding through a combination of equity or debt financings, or other third-party financing, collaborative or other funding arrangements.
