4. Fair Value Measurements

ASC 820, Fair Value Measurement, the authoritative guidance on fair value measurements, establishes a framework with respect to measuring assets and liabilities at fair value on a recurring basis and non-recurring basis. Under the framework, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as of the measurement date. The framework also establishes a three-tier hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability, and are developed based on the best information available in the circumstances. The hierarchy consists of the following three levels:

Level 1: Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

Level 2: Inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3: Inputs are unobservable inputs for the asset or liability.

The Company’s Level 1 assets include money market instruments and are valued based upon observable market prices. The Company’s Level 1 liabilities included the Penny Warrants (as defined below) which were valued based upon observable market prices. Level 2 assets consist of U.S Treasury securities. Level 2 securities are valued based upon observable inputs that include reported trades, broker/dealer quotes, bids and offers. The corporate-owned life insurance contracts are recorded at cash surrender value, which approximates the fair value and is categorized as Level 2. Non-qualified deferred compensation plan liability is measured at fair value based on quoted prices of identical instruments to the investment vehicles selected by the participants, and is recorded as Level 2. There were no transfers between fair value measurement levels during the periods ended March 31, 2026 and December 31, 2025.

Loan Facility

The fair value of the loan facility was determined using a discounted cash flow method to value the initial term loan using a risk-free interest rate of 3.90% as of March 31, 2026. The valuation was performed based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The fair value of the loan facility is recorded in the Consolidated Balance Sheets. The fair value is estimated by the Company each reporting period and the change in the fair value is recorded in both earnings and other comprehensive income, depending on both the instrument's inherent credit risk and the market risk related to the debt valuation.

Warrant Liabilities

On the Closing Date, as defined in Note 6 to the Consolidated Financial Statements, the Company agreed to issue, subject to shareholder approval, warrants to purchase up to 650,000 shares of Common Stock, par value $0.0001 per share, at an exercise price set at the lower of two 10-day VWAPs: (i) the 10-day VWAP ending on the business day immediately prior to the Closing Date (i.e., 12 January 2026), which VWAP is $3.4019; or (ii) the 10-day VWAP ending on the business day immediately prior to the issuance date of the warrants (the “Perceptive Warrants”). The fair value of the Perceptive Warrants liability was determined based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The fair value of the Perceptive Warrants liability, which is reported within Warrant liabilities on the Consolidated Balance Sheets, is estimated by the Company based on the Black-Scholes option pricing model with the following key inputs:

On February 13, 2025, the Company issued 145,180 warrants with an exercise price of $0.01 per share (the “Penny Warrants”). The Penny Warrants were issued in connection with the Previous Credit Agreement as defined in Note 6 of the Consolidated Financial Statements. On March 4, 2026, the Penny Warrants were exercised and 144,895 shares of the Company’s common stock (“Common Stock”) were issued.

The fair value of the Penny Warrants liability was determined based on quoted prices in active markets, which represents a Level 1 measurement within the fair value hierarchy. The fair value of the Penny Warrants liability, which was reported within Warrant liabilities on the Consolidated Balance Sheets, was estimated by the Company based on the closing price of the Common Stock as quoted on the Nasdaq Capital Market (“Nasdaq”) under the ticker code, “RCEL.”

On October 18, 2023, the Company issued 409,661 warrants with an exercise price of $10.9847 per share as consideration for the Previous Credit Agreement as defined in Note 6 to the Consolidated Financial Statements. As a result of the issuance of Common Stock via a private placement on the ASX on August 12, 2025, the exercise price of these warrants was adjusted to $10.218 (the “$10.218 Warrants”). The fair value of the $10.218 Warrants liability was determined based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The fair value of the $10.218 Warrants liability, which is reported within Warrant liabilities on the Consolidated Balance Sheets, is estimated by the Company based on the Black-Scholes option pricing model with the following key inputs:
