Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company categorizes financial assets and liabilities into the three levels of the fair value hierarchy. The hierarchy prioritizes the inputs to valuation techniques used to measure fair value and bases categorization within the hierarchy on the lowest level of input that is available and significant to the fair value measurement.
•Level 1 — Quoted prices in active markets for identical assets or liabilities;
•Level 2 — Observable inputs other than Level 1, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and
•Level 3 — Significant unobservable inputs that are supported by little or no market activity or that are based on the reporting entity’s assumptions about the inputs.
Fair Value of Other Financial Instruments
The carrying amounts of certain financial instruments, including cash and cash equivalents, restricted cash, accounts receivable, accrued liabilities, accounts payable and ABL approximate fair value due to the short-term nature of these accounts.
Liabilities Measured at Fair Value on a Recurring Basis

The following table presents the Company’s liabilities that are measured at fair value on a recurring basis and the level within the fair value hierarchy (in thousands):

Contingent Earnout Consideration Key Inputs
The estimated fair value of the remaining stock performance earn-out provision, with respect to the JP3 transaction, is included in accrued liabilities as of September 30, 2024 and December 31, 2023. The estimated fair value of the earn-out provision at the end of each period was valued using a Monte Carlo model analyzing 20,000 simulations performed using Geometric Brownian Motion with inputs such as risk-neutral expected growth and volatility.
