4. Fair Value Measurements

In accordance with ASC 820 (Fair Value Measurements and Disclosures), the Company uses various inputs to measure the fair value of liabilities related to certain embedded conversion feature associated with its warrant liability, convertible debt, share payable, and contingent payable to Cognate BioServices on a recurring basis to determine the fair value of these liabilities. The Company has also elected the fair value option (the “FVO”) for certain financial instruments, such as convertible notes.

ASC 820 establishes a hierarchy categorizing inputs into three levels used to measure and disclose fair value. The hierarchy gives the highest priority to quoted prices available in active markets and the lowest priority to unobservable inputs. An explanation of each level in the hierarchy is described below:

Level 1 - Unadjusted quoted prices in active markets for identical instruments that are accessible by the Company on the measurement date.

Level 2 - Quoted prices in markets that are not active or inputs which are either directly or indirectly observable.

Level 3 - Unobservable inputs for the instrument requiring the development of assumptions by the Company.

The following table classifies the Company’s liabilities measured at fair value on a recurring basis into the fair value hierarchy as of March 31, 2026 and December 31, 2025 (in thousands):

There were no transfers between Level 1, 2 or 3 during the three-month period ended March 31, 2026.

The following table presents changes in Level 3 liabilities measured at fair value for the three-month period ended March 31, 2026. Both observable and unobservable inputs were used to determine the fair value of positions that the Company has classified within the Level 3 category. Unrealized gains and losses associated with liabilities within the Level 3 category include changes in fair value that were attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long- dated volatilities) inputs (in thousands).

(1)The fair value of the contingent payable derivative liability was reduced to zero as of March 31, 2026, because the underlying performance condition required for payment is not probable prior to the note’s expiration on May 21, 2026.

A summary of the weighted average (in aggregate) significant unobservable inputs (Level 3 inputs) used in measuring the Company’s share payable that are categorized within Level 3 of the fair value hierarchy as of March 31, 2026 and December 31, 2025 is as follows. The liability relates to the remaining redemption feature which, like the convertible notes at fair value, includes discount factors that are unobservable inputs and proprietary in nature.
