(12) Stock-Based Compensation

 

In September 2021, the Company’s board of directors and stockholders adopted the 2021 Equity Incentive Plan ( 2021 Plan), which provides for the grant of incentive stock options and non-qualified stock options to purchase shares of the Company’s common stock, stock appreciation rights, restricted stock units, restricted or unrestricted shares of common stock, performance shares, performance units, incentive bonus awards, other stock-based awards and other cash-based awards. No awards may be made under the 2021 Plan on or after September 24, 2031, but the 2021 Plan will continue thereafter while previously granted awards remain outstanding.

 

At the Company’s 2024 annual meeting, shareholders approved an amendment to the 2021 Plan to increase the number of shares of common stock authorized for issuance thereunder by 104,167 shares to 125,577. At the Company’s 2025 annual meeting, shareholders approved an amendment to the 2021 Plan to increase the number of shares of common stock authorized for issuance thereunder by 800,000 shares to 1,141,826. As of December 31, 2025, 185,831 shares of common stock were available for issuance under the 2021 Plan. The number of shares of common stock available for issuance under the 2021 Plan will automatically increase on January 1st of each year until the expiration of the 2021 Plan, in an amount equal to 5% percent of the total number of shares of our common stock outstanding on December 31st of the preceding calendar year, on a fully diluted basis, unless the board of directors takes action prior thereto to provide that there will not be an increase in the share reserve for such year or that the increase in the share reserve for such year will be of a lesser number of shares of common stock than would otherwise occur. The shares of common stock underlying any awards that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, repurchased or are otherwise terminated by the Company under the 2021 Plan will be added back to the shares of common stock available for issuance under the 2021 Plan.

 

The Company recorded stock-based compensation expense of $1,408,134 and $995,484 during the years ended December 31, 2025 and 2024, relating to options granted under the 2021 Plan. As of December 31, 2025 and 2024, there was $2,449,227 and $343,612 of unrecognized compensation cost related to nonvested share-based compensation arrangements granted under the 2021 Plan, which is expected to be recognized over the next one to four years.

 

 

A summary of option activity under the 2021 Plan during the years ended December 31, 2025 and 2024 was as follows:

The Company’s stock options issued qualify for equity accounting treatment under ASC 718, Compensation- Stock Compensation, and are measured at fair value as of their grant date accordingly. The fair value of the options were estimated using a Black-Scholes model. The assumptions that the Company used to estimate the grant-date fair value of stock options granted to employees and directors were as follows, shown on a weighted average basis for the respective years ended:

 

   2025   2024 
Risk-free interest rate   4.150%   4.240%
Expected term (in years)   5.82    5.43 
Expected volatility   1.4    1.5 
Expected dividend yield   0%   0%

 

Risk-Free Interest Rate: The Company based the risk-free interest rate over the expected term of the options based on the constant maturity of U.S. Treasury securities with similar maturities as of the date of grant.

 

Expected Term: The expected term represents the period that the options granted are expected to be outstanding and is determined using the simplified method (based on the mid-point between the vesting dates and the end of the contractual term.)

 

Expected Volatility: The Company uses an average historical stock price volatility of comparable public companies within the biotechnology and pharmaceutical industry that were deemed to be representative of future stock price trends as the Company does not have sufficient trading history for its common stock. The Company will continue to apply this process until a sufficient amount of historical information regarding volatility of its own stock price becomes available.

 

Expected Dividend Yield: The Company has not paid and does not anticipate paying any dividends in the near future. Therefore, the expected dividend yield was zero.

 

The grant-date fair value of options granted during the year ended December 31, 2025 ranged from $3.44 to $4.22 and $3.46 to $13.34 for options granted during the year ended December 31, 2024.

 

 

The aggregate intrinsic value of stock options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock. Because there were no stock options with exercise prices lower than the fair value of the Company’s common stock, the aggregate intrinsic value is zero as of December 31, 2025 and 2024.

 

On each of July 8, 2025 and November 3, 2025, the Company granted non-qualified stock options to an officer of the Company to purchase 30,000 shares of common stock at an exercise price of $4.51 and $3.80, respectively. These grants were inducement awards in accordance with Nasdaq Listing Rule 5635(c)(4) and were not granted from the 2021 Plan. The term of these options is ten years with vesting over four years. The Company recorded stock-based compensation expense of $19,135 during the year ended December 31, 2025 relating to options issued. As of December 31, 2025, there was $209,975 of unrecognized compensation cost related to nonvested share-based compensation related to the inducement grants, which is expected to be recognized over the next one to four years.

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.
