STOCKHOLDERS’ EQUITY, EMPLOYEE BENEFIT PLANS AND SHARE-BASED COMPENSATION
Shelf Registration
In April 2024, we filed a universal shelf registration statement on Form S-3 with the Securities and Exchange Commission (“SEC”) to provide access to additional capital, if needed. Pursuant to the shelf registration statement, we may from time to time offer to sell in one or more offerings shares of our common stock or other securities having an aggregate value of up to $150,000. The shelf registration statement relating to these securities became effective on April 19, 2024. As of December 31, 2025, there is $150,000 available under the shelf registration statement.
Also in April 2024, we filed an acquisition shelf registration statement on Form S-4 with the SEC to allow us to issue securities in future business combinations. Pursuant to the acquisition shelf registration statement, we may from time to time issue up to 12,500 shares of our common stock as consideration in future business combinations. The shelf registration statement relating to these securities became effective on April 19, 2024. As of December 31, 2025, there are 12,500 shares of common stock available for issuance under this acquisition shelf registration statement.
On October 31, 2024, we entered into a Sales Agreement (the “Sales Agreement”) with Roth Capital Partners, LLC (“Roth”). The Sales Agreement provides for the offer and sale of up to $25,000 of our newly issued common stock as registered under the April 2024 shelf registration, from time to time through an “at the market offering” program. We will specify the parameters for the sale of the shares of common stock, including the number of shares to be issued, the time period during which sales are requested to be made, any limitation on the number of shares that may be sold in any one trading day and any minimum price below which sales may not be made. We may offer and sell up to $25,000 of shares of common stock pursuant to the Sales Agreement. Actual sales of common stock under the Sales Agreement will depend on a variety of factors including, among other things, market conditions, the trading price of the common stock and potential funding needs. As a result, the full amount of capital may not be fully realized. We intend to use the net proceeds from these at-market offerings, if any, for general corporate purposes. Our general corporate purposes include, but are not limited to, repayment or refinancing of debt, capital expenditures, funding possible acquisitions, working capital and satisfaction of other obligations. As of December 31, 2025, there are $25,000 of shares of common stock available for issuance under the Sales Agreement.
Stock and Stock Option Plans
We have one active equity plan, the 2018 Incentive Award Plan (the “2018 Plan”).
Employees and consultants of the Company, its subsidiaries and affiliates, as well as members of our board, are eligible to receive awards under the 2018 Plan. The 2018 Plan provides for the grant of stock options, including incentive stock options (“ISOs”) and nonqualified stock options (“NQSOs”), stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance bonus awards, performance stock unit awards (“PSUs”), other stock or cash-based awards and dividend equivalents to eligible individuals.
The number of shares available for issuance under the 2018 Plan is 6,998 shares. We have 819 options, 820 RSUs, and 558 PSUs granted and outstanding pursuant to the 2018 Plan as of December 31, 2025.
We use the Black-Scholes option valuation model to value employee stock awards. We estimate stock price volatility based upon our historical volatility. Estimated option life and forfeiture rate assumptions are derived from historical data. For stock-based compensation awards with graded vesting, we recognize compensation expense using the straight-line amortization method. During the years ended December 31, 2025 and 2024, we have not issued any stock options as compensation.
Total compensation expense recognized in the Consolidated Statements of Comprehensive Loss for stock based awards was $7,739 and $6,444 for 2025 and 2024, respectively.

Employee Stock Purchase Plan

Under the ESPP, 875 shares were reserved for issuance of which there remains 295 shares available for future issuance.
