9. Fair Value Measurements

The carrying amounts of certain financial instruments, including cash and cash equivalents, restricted cash, investments, prepaid expenses and other current assets, accounts payable, and accrued expenses approximate their respective fair values due to the short-term nature of such instruments.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company evaluates its financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level in which to classify them for each reporting period. This determination requires significant judgments to be made. The following table summarizes the conclusions reached as of June 30, 2026 and December 31, 2025 for financial instruments measured at fair value on a recurring basis (in thousands):

The Company measures cash equivalents at fair value on a recurring basis. The fair value of cash equivalents is determined based on “Level 1” inputs, which consist of quoted prices in active markets for identical assets. As of June 30, 2026, the cash and cash equivalents of $10.5 million and the restricted cash balances of $0.1 million within short term and $0.1 million in long term on the unaudited condensed consolidated balance sheet, sum to the total of $10.7 million as shown in the unaudited condensed consolidated statement of cash flows.

Level 3 financial liabilities consist of the warrant liabilities for which there is no current market such that the determination of fair value requires significant judgment or estimation. Changes in fair value measurements categorized within Level 3 of the fair value hierarchy are analyzed each period based on changes in estimates or assumptions and recorded as appropriate. The Company uses the Black-Scholes option valuation model to value the Level 3 warrant liabilities at inception and on subsequent valuation dates. This model incorporates transaction details such as the Company’s stock price, contractual terms, maturity, risk free rates, as well as volatility. The unobservable inputs for the Level 3 warrant liabilities include volatility and expected term. The historical and implied volatility of the Company, using its closing common stock prices and market data, is utilized to reflect future volatility over the expected term of the warrants.

At June 30, 2026 and December 31, 2025, the Level 3 volatility utilized in the Black-Scholes model to fair value the April 2022 public offering warrant liability was 77.3% and 86.1%, respectively. At June 25, 2026, the Level 3 volatility utilized in the Black-Scholes model to fair value the March 2026 Private Placement common warrants liability was 74.1%. The Company utilized a probability assessment to estimate the expected term for the Common Warrants associated with the March 2026 Private Placement. At June 25, 2026, the estimated expected term for the Common Warrants was 2.12 years.

A reconciliation of the beginning and ending balances for liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) is as follows (in thousands):
