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 and accounts payable 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 March 31, 2023 and December 31, 2022. 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.

Initial ProFrac Agreement Contract Consideration Notes Payable Key Inputs
The Initial ProFrac Agreement Contract Consideration Convertible Notes Payable were measured at fair value at issuance and on a recurring basis. The Initial ProFrac Agreement Contract Consideration Convertible Notes Payable had an initial fair value of $10.0 million on February 2, 2022. The Initial ProFrac Agreement Contract Consideration Convertible Notes Payable were classified as Level 2 at the initial measurement upon issuance due to the use of a quoted price for a similar liability at that date (the PIPE transaction), and subsequently classified as Level 3 due to the use of unobservable inputs.
On February 2, 2023, the Initial ProFrac Agreement Contract Consideration Convertible Notes Payable were remeasured, at maturity, to a fair value of $15.1 million based on the closing price of the shares of common stock of $1.19, on the date of conversion. The fair value adjustment was a $0.8 million increase and a $3.9 million decrease in the three months ended March 31, 2023 and 2022, respectively.
The estimated value of the Initial ProFrac Agreement Contract Consideration Convertible Notes Payable as of December 31, 2022 was valued using a Monte Carlo simulation. The key inputs into the Monte Carlo simulation used to estimate the fair value of the Initial ProFrac Agreement Contract Consideration Convertible Notes Payable maturing February 2, 2023, as of December 31, 2022 were as follows:
December 31, 2022
Risk-free interest rate4.12%
Expected volatility100.0%
Term until liquidation (years)0.09
Stock price$1.12
Discount rate4.12%

Amended ProFrac Agreement Contract Consideration Convertible Notes Payable Key Inputs
On May 17, 2022, the Company measured the Amended ProFrac Agreement Contract Consideration Convertible Notes Payable classified as Level 3 using a Monte Carlo simulation at an estimated fair value of $69.5 million. The Company reduced the discount rate assumed due to the reduced likelihood of occurrence of any of the default events in the shorter term remaining on the notes. The estimated value of the Amended ProFrac Agreement Contract Consideration Convertible Notes Payable as at March 31, 2023 and December 31, 2022 was valued using a Monte Carlo simulation.
The key inputs into the Monte Carlo simulation used to estimate the fair value of the Amended ProFrac Agreement Contract Consideration Convertible Notes Payable, as of March 31, 2023 and December 31, 2022 were as follows:
March 31, 2023December 31, 2022

Assets Measured at Fair Value on a Nonrecurring Basis
The Company’s non-financial assets, including property and equipment and operating lease ROU assets, are measured at fair value on a non-recurring basis and are subject to adjustment to their fair value in certain circumstances.
