Fair Value Measurements

Note 14 — Fair Value Measurements

 

The carrying amounts of the Company’s cash, accounts receivable and accounts payable approximate their fair value due to the short-term nature of these instruments. The Company believes the aggregate carrying value of debt approximates its fair value as of March 31, 2026 and September 30, 2025 because the notes payable, the 7% promissory notes - related parties and the notes payable - related parties each mature within one to two years of the respective balance sheet dates.

 

Fair Value Hierarchy

 

Liabilities measured at fair value on a recurring basis as of March 31, 2026 are as follows:

 

   Level 1   Level 2   Level 3   Total 
Earnout liability  $—   $—   $280   $280 
Liability-classified warrants   —    —    375    375 
                     
Total  $—   $—   $655   $655 

 

The Company classifies the earnout liability and the liability-classified warrants as Level 3 financial instruments due to the judgment required to develop the assumptions used and the significance of those assumptions to the fair value measurement. No financial instruments were transferred between levels of the fair value hierarchy during the six months ended March 31, 2026 or 2025. The following table provides a reconciliation of the balance of financial instruments measured at fair value on a recurring basis using Level 3 inputs:

Liability-Classified Warrants

 

As of March 31, 2026, liability-classified warrants consist of the Private Warrants. The Company estimates the fair value of the Private Warrants based on quoted market prices for the Public Warrants, which have substantially the same economic characteristics. As of September 30, 2025, the Company estimated the fair value of liability-classified warrants (other than the Private Warrants)—including those amended during the six months ended March 31, 2026—using the Black-Scholes option pricing model. The following table summarizes the significant assumptions used in estimating the fair value of liability-classified warrants under the Black-Scholes option pricing model:

 

  

September 30,

2025

 
Stock price  $8.06 
Expected volatility   79.0%
Risk-free rate   3.7%
Contractual term   4.3 – 4.9 years 

 

 

Earnout Liability

 

The Company estimates the fair value of the earnout liability using a Monte Carlo simulation model that utilizes significant assumptions, including volatility, expected term and risk-free rate that determine the probability of achieving the earnout conditions. The following table summarizes the assumptions used in estimating the fair value of the earnout liability at the respective dates:

 

  

March 31,

2026

  

September 30,

2025

 
Stock price  $3.34   $8.06 
Expected volatility   90.0%   80.0%
Risk-free rate   3.8%   3.8%
Contractual term   5.7 years    6.2 years
