To support its current operations, the Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. The restricted cash component is related to accrued holdbacks for business combinations (see Note 1, The Company and Significant Accounting Policies).
The Company uses the Black-Scholes option-pricing valuation model to value its detachable warrants from inception and at each reporting period. During the three months ended March 31, 2026, the Company used historical volatility to determine the fair value of the warrants liability due to the low trading volume and moneyness assessment as of March 31, 2026. Changes in the fair values of the detachable warrants liability are recorded as a gain (loss) on warrants remeasurement within other income (expense), net in the consolidated statements of operations and comprehensive income (loss).
The following table presents additional information about valuation techniques and inputs used for the detachable warrants (see Note 8, Convertible Senior Notes and Term Loan) that are measured at fair value and categorized within Level 3 as of March 31, 2026 and March 31, 2025 (dollars in thousands):

As of March 31, 2026 and March 31, 2025, the estimated fair value of the Company's convertible senior notes due in 2028 was $187.7 million and $171.1 million, respectively (see Note 8, Convertible Senior Notes and Term Loan). The fair value of the convertible senior notes was determined based on the closing price of each of the securities on the last trading day of the reporting period, and each is Level 2 in the fair value hierarchy due to limited trading activity of the debt instruments. As of March 31, 2026 and 2025, the carrying value of the Company's Term Loan approximates its estimated fair value.

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.
