[1] Reflects a probability-weighted input derived from multiple Black-Scholes calculations. These calculations incorporate the Company’s estimated probability of survival, assuming SABS’ intellectual property yields positive results in forthcoming clinical trials, allowing the Company to continue as a going concern rather than face dissolution before 2028. The probability of survival was 57.5% and 40.0% as of June 30, 2026 and December 31, 2025, respectively.
