Fair Value Measurements

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. Financial instruments, including cash, inventory, accounts receivable, accounts payable, accrued liabilities, operating lease liabilities, and notes payable are carried at cost, which management believes approximates fair value due to the short-term nature of these instruments.

The fair value of the contingent warrant liability and Series D and E derivative liabilities are valued using significant unobservable measures and other fair value inputs and are therefore classified as Level 3 financial instruments.

The fair value of financial instruments measured on a recurring basis is as follows as of June 30, 2026 and December 31, 2025:

These non-financial assets had been valued using significant unobservable measures and other fair value inputs and were classified as Level 3 measurements.

None of the Company’s other non-financial assets or liabilities are recorded at fair value on a non-recurring basis as of June 30, 2026 and December 31, 2025. There were no transfers between levels during the periods presented.
