Fair Value Measurements
Fair value is an exit price representing the expected amount that an entity would receive to sell an asset or pay to transfer a liability in an orderly transaction with market participants at the measurement date. We followed consistent methods and assumptions to estimate fair values as more fully described in Note 1.
Embedded Derivatives
In accordance with ASC 815-15, Derivatives and Hedging - Embedded Derivatives, certain features of our preferred stock and long-term debt were bifurcated and accounted for as derivatives separately.
In conjunction with an amendment to our 2021 Term Loan in 2023, we issued warrants to purchase up to 2.0 million shares of our common stock at an exercise price of $0.01 per share (the “2023 Warrants”). The 2023 Warrants are exercisable, in full or in part, at any time prior to June 30, 2033. The 2023 Warrants include anti-dilution adjustments in the event of certain future equity issuances, stock splits, stock dividends, combinations or similar events. During the year ended December 31, 2024, 500,000 of the 2023 Warrants were exercised on a cashless basis, resulting in the issuance of 499,000 shares.
In conjunction with our placement of the Series D Preferred Stock in 2021, we issued warrants to purchase up to 1.9 million shares of our common stock (the “2021 Warrants”). The 2021 Warrants were exercisable, in full or in part, at an exercise price of $0.01 per share, subject to anti-dilution adjustments in the event of certain future equity issuances, stock splits, stock
dividends, combinations or similar events. During the year ended December 31, 2024, all of the 2021 Warrants were exercised on a cashless basis, resulting in the issuance of 1,896,000 shares.
In conjunction with our placement of the Series B Preferred Stock in 2019, we issued warrants to purchase up to 1.5 million shares of our common stock (the “2019 Warrants”). The 2019 Warrants, are exercisable, in full or in part, at any time prior to December 11, 2026, at an exercise price of $11.03 per share, and are subject to anti-dilution adjustments in the event of future below market issuances, stock splits, stock dividends, combinations or similar events.

The fair value of the 2023 Warrants and 2021 Warrants is determined using the observable market price of a share of our common stock, less the $0.01 per share exercise price (Level 1).
The fair value of the 2019 Warrants is determined using a valuation model that utilizes unobservable inputs to determine the probability that the 2019 Warrants will remain outstanding for future periods (Level 3). The probabilities resulted in a weighted average term of 1.3 years as of December 31, 2025 and 2.0 years as of December 31, 2024.
Interest Rate Swap
On July 22, 2021, we entered into a fixed-rate interest rate swap agreement to change the applicable variable base rate component of the interest rate on a portion of our variable rate debt to a fixed rate of 1.291% (the “2021 Swap”). The 2021 Swap had a notional amount of $60.0 million and a maturity date of July 31, 2024. We designated the 2021 Swap as a cash flow hedge at inception with cash settlements recognized in interest expense. During the first quarter of 2023, we terminated the 2021 Swap and received cash proceeds of $2.5 million which was the fair value of the 2021 Swap. Since the 2021 Swap was an effective cash flow hedge and the forecasted interest payments remain probable of occurring, the gain was recognized as a reduction to interest expense through the original maturity date of July 31, 2024.
During the years ended December 31, 2024 and 2023, we recognized an interest benefit of $1.0 million and $1.8 million, respectively, from gains recognized in interest expense on the effective interest rate swap in the Consolidated Statements of Operations and Comprehensive Income (Loss).
Fair Value Disclosures
Our financial instruments that are subject to fair value disclosure consist of cash and cash equivalents, accounts receivable, accounts payable, and debt. As of December 31, 2025 and 2024, the carrying values of these financial instruments, except for debt, approximated fair value. The fair value of our debt was $156.9 million and $147.8 million, with a carrying amount of $159.5 million and $148.6 million, as of December 31, 2025 and 2024, respectively. The fair value of debt was calculated by discounting the future cash flows to its present value using prevailing market interest rates for debt with similar creditworthiness, terms and maturities (Level 3).

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
