Fair Value Disclosures [Abstract]  
Fair Value of Financial Instruments Fair Value of Financial Instruments
Cash and cash equivalents, accounts receivable, inventories, prepaid expenses and other current assets, accounts payable, salaries and benefits payable, accrued interest, other accrued expenses and current liabilities are reflected on the condensed consolidated balance sheets at amounts that approximate fair value because of the short-term nature of these financial assets and liabilities.
The fair value of the Company’s debt approximates its carrying value and is classified as Level 2 within the fair value hierarchy as it is based on discounted cash flows using a current borrowing rate.
Private Warrants
The private warrants were valued using a modified Black-Scholes OPM, which is classified as Level 3 within the fair value hierarchy. The following table presents the fair value per warrant and the valuation assumptions under the Black-Scholes OPM as of March 31, 2022 and December 31, 2021.
March 31, 2022 December 31, 2021
Fair value $ 2.63  $ 2.47 
Exercise price $ 11.50  $ 11.50 
Common stock price $ 8.48  $ 6.75

Expected volatility 45.90  % 60.50  %
Risk-free rate of return 2.41  % 1.21  %

Changes in the fair value of the private warrants are included in other (income) expense, net on the condensed consolidated statements of operations and comprehensive income (loss).

Contingent Consideration
As of March 31, 2022 and December 31, 2021, contingent consideration consisted of estimated future payments related to the Company’s acquisition of Roccor. As certain inputs are not observable in the market, contingent consideration payments are classified as Level 3 instruments and included in notes payable to seller on the condensed consolidated balance sheets. Significant changes in the significant unobservable inputs used in the Black-Scholes OPM to determine the fair value of contingent consideration would result in a significantly lower or higher fair value measurement. The Company adjusts the previous fair value estimate of contingent consideration at each reporting period while considering changes in forecasted financial performance and overall change in risk based on the period of time elapsed.

The purchase agreement with the sellers of Roccor awarded such sellers with a contingent right to an earnout payment from the Company upon the achievement of certain revenue milestones for the year ended December 31, 2021. The fair value of the Roccor contingent earnout was estimated using the Black-Scholes OPM. 

The assumptions used in the Black-Scholes OPM were as follows:
Roccor Black-Scholes OPM Assumptions
Risk-free interest rate
0.1  %
Revenue discount rate
7.0  %
Revenue volatility
30.0  %
Earnout payment discount rate
4.0  %

As of March 31, 2022, the Company expects to pay the Roccor contingent earnout during the second half of 2022 in accordance with the acquisition agreement.
Financial liabilities measured at fair value on a recurring basis are as follows:
