Note 12 — Stock-Based Compensation

The Company has the following Stock Option Plans (“Plans”) that allow for the grants of both incentive stock options or ISOs, which can result in potentially favorable tax treatment to the participant, and non-statutory stock options. The Company’s 2023 Equity Incentive Plan (the “2023 Plan”) was approved by the stockholders of the Company on June 15, 2023. The Company no longer issues any options under its prior 2014 Plan. The 2023 Plan no longer contains an “evergreen provision”. As of December 31, 2023, the authorized shares of common stock under the 2023 Plan, as amended, were 12,641,637.

The exercise price per share subject to an option is determined by the administrator, but in the case of an ISO must not be less than the fair market value of a share of our common stock on the date of grant and in the case of a non-statutory stock option must not be less than 100% of the fair market value of a share of our common stock on the date of grant.

Under the 2023 Plan, the Company may grant stock options, stock appreciation rights, performance awards of stock and/or cash, and stock awards of restricted stock.

Options issued or outstanding under the Stock Options Plans are as follows:

The 2023 Plan gives the Board of Directors of the Company the ability to determine vesting periods for all stock incentives granted under the 2023 Plan and allows option terms to be up to ten years from the original grant date. Employees’ incentive stock options typically vest at a minimum rate of 25% per year over a four-year period, commencing on the date of grant.

The following table summarizes stock option activity related to the Company’s standard employee incentive plan, excluding options awarded under the Long-term Incentive Plan (LTIP), for the years ended December 31, 2024, 2023, and 2022:

As of December 31, 2022, there were 1,493,707 options that were fully-vested and exercisable at a weighted average exercise price of $6.88 per share. The weighted average remaining contractual term on the vested options is 6.3 years.

The aggregate intrinsic value of the options exercised during the year ended December 31, 2024, 2023, and 2022 was approximately $333,091, $85,263 and $627,876, respectively. The aggregate intrinsic value of the options outstanding as of December 31, 2024, 2023, and 2022 was approximately $9,801,292, $563,874 and $2,093,164, respectively.

The Black-Scholes-Merton option pricing model was used to estimate the fair value of share-based awards under FASB ASC Topic 718. The Black-Scholes-Merton option pricing model incorporates various and highly subjective assumptions, including expected term and share price volatility. The expected term of options granted was estimated to be the average of the vesting term, historical exercise and forfeiture rates, and the contractual life of the option. The share price volatility at the grant date is estimated using historical stock prices based upon the expected term of the options granted. The risk-free interest rate assumption is determined using the rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. We have never paid cash dividends on our common stock and do not anticipate paying cash dividends on our common stock in the foreseeable future. Therefore, the assumed expected dividend yield is zero.

The following summary table shows the assumptions used to compute the fair value of stock options granted, excluding LTIP, during 2024, 2023, and 2022 and their estimated value:

Under FASB ASC Topic 718, “Compensation – Stock Compensation”, the Company has elected to account for forfeitures as they occur.

Unrecognized stock-based compensation expense was $2,059,376 as of December 31, 2024, relating to a total of 2,796,369 unvested stock options under the Company’s stock option plans. This stock-based compensation expense is expected to be recognized over a weighted average period of approximately 1 year.

During the year ended December 31, 2024, the Company issued 232,766 shares of common stock to its independent board members as part of their annual retainer for services covering the period of July 2024 to June 2025 and for the onboarding of the new director. The fair market value on the date of award of the stock issued was $1.41, resulting in an aggregate fair value of approximately $328,200. The fair market value of these awards is expensed over twelve (12) months for 212,766 shares and twenty-four (24) months for 20,000 shares beginning on July 1, 2024.

On May 6, 2024, the Company implemented a voluntary Company-wide payroll reduction program for all employees, independent board members and contractors with optional salary or compensation reductions of 10% to 50% depending upon the respective base salary or compensation level for the period running from May 1, 2024 to April 30, 2025. The fair market value of these stock awards and stock option awards has been determined at $1.33 and $0.99, respectively, and a total of 824,711 stock awards and 2,756,116 stock option awards were issued. The total fair market value of the stock awards is $1,096,865 and the stock option awards is $2,728,555. The fair market value of these awards is being expensed over twelve (12) months, which began on May 1, 2024 and will cliff vest on April 30, 2025.

The estimated cash savings will be approximately $2,100,000 and resulted in the issuance of stock awards and stock options, at a rate of 150% or 200%, respectively, of the net cash wage reductions.

For the years ended December 31, 2024, 2023, and 2022, the Company recorded total stock-based compensation expense, including stock awards but excluding awards under the Company’s LTIP of $5,928,198, $4,566,253, and $4,645,026, respectively.

About Stock Compensation Disclosures

Stock-based compensation disclosures detail the equity awards granted to employees and executives — including stock options, restricted stock units (RSUs), and performance shares — along with the valuation methods and assumptions used to expense them. This section reveals the true cost of talent retention and the alignment between management incentives and shareholder interests.

Key signals: total unrecognized compensation expense and its expected recognition period signal future earnings headwinds from already-granted awards. For stock options, examine Black-Scholes assumptions — expected volatility, risk-free rate, and expected term — as understating any of these reduces reported compensation expense. Compare stock compensation expense as a percentage of revenue against peers to assess dilution cost. Watch vesting schedules for acceleration clauses tied to change-of-control events. Performance-based awards with undemanding targets may indicate weak governance. Add back stock compensation to operating cash flow to calculate a more conservative free cash flow figure.
