FAIR VALUE

FAIR VALUE

The Company follows the guidance in ASC Topic 820, Fair Value Measurement. For assets and liabilities measured at fair value on a recurring and nonrecurring basis, a three-level hierarchy based upon observable and unobservable inputs is used to arrive at fair value. The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

•Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

•Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

•Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

As of March 31, 2025 and December 31, 2024, the carrying amount of accounts receivable, prepaid expenses and other assets, emissions and carbon offset credits, accounts payable, accrued expenses, accrued emissions expense, and other short-term liabilities approximated their fair value due to their relatively short maturities.

The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis and indicate the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value (in thousands):

Assets Measured on a Nonrecurring Basis

Assets that are measured at fair value on a nonrecurring basis are remeasured when carrying value exceeds fair value. This includes the evaluation of long-lived assets. Where an indication of an impairment exists, the Company’s estimates of fair value of long-lived assets require the use of significant unobservable inputs, representative of Level 3 fair value measurements, including numerous assumptions with respect to future circumstances that might impact the long-lived assets’ operations in the future and are therefore uncertain.

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. To determine recoverability of a long-lived asset, management evaluates whether the estimated future undiscounted net cash flows, based on prevailing market conditions, from the asset are less than its carrying amount. If impairment is indicated, the long-lived asset is written down to fair value.

There were no impairment charges for the three months ended March 31, 2025. The Company recognized impairment charges of $0.2 million of property and equipment during the three months ended March 31, 2024.
