Q1 2024 Financial Results

Financial Guidance: Based on its current operating plans, SAB reaffirms it has sufficient cash, assuming the receipt of funds upon the exercise of all outstanding Tranche B warrants, that is expected to be sufficient to fund its operations into 2026.

• Cash Position: Cash, cash equivalents, and available for sale securities totaled $45.2 million as of March 31, 2024 compared to $56.6 million as of December 31, 2023, driven primarily by continued research and related expenses as we advance our lead therapeutic candidates.
• Research and Development (R&D) Expenses: R&D expenses were $7.1 million for three months ended March 31, 2024, compared to $4.5 million for the three months ended March 31, 2023. The increase was primarily due to prioritizing focus in the autoimmunity space with SAB-142, a disease-modifying fully human hIgG aimed at preventing onset or disease progression of T1D.
• General and Administrative Expense: G&A expenses were $4.2 million for the three months ended March 31, 2024, compared to $3.4 million for the three months ended March 31, 2023. G&A expenses grew primarily due to increased headcount to support our continued research activities and development of our product candidates.
• Non-operating Income: Non-operating income was $6.4 million for the three months ended March 31, 2024, compared to $48,000 for the three months ended March 31, 2023. This increase was primarily due to the change in fair value of warrant liabilities and an Australian research and development tax credit.
