12. EQUITY INCENTIVE PLAN

The Company currently issues stock awards under its 2017 Stock Option and Incentive Plan, as amended (the "2017 Plan") which will expire on June 5, 2027.  The shares authorized for issuance under the 2017 Plan were 395,380 at December 31, 2025 of which 18,234 were available for future grant. The shares authorized under the 2017 Plan are subject to annual increases on January 1 by 5% of the number of shares of common stock issued and outstanding on the immediately preceding December 31, or such lessor number of shares determined by the Company’s Board of Directors or Compensation Committee. During the year ended December 31, 2025, the shares authorized for issuance increased by 74,681 shares.

The Plan is administered by the Compensation Committee of the Board of Directors (the “Committee”), which has the authority to set the number, exercise price, term and vesting provisions of the awards granted under the Plan, subject to the terms thereof. Either incentive or non-qualified stock options may be granted to employees of the Company, but only non-qualified stock options may be granted to non-employee directors and advisors. However, in either case, the Plan requires that stock options must be granted at exercise prices not less than the fair market value of the common stock

on the date of the grant. Options issued under the plan vest over periods as determined by the Committee and expire 10 years after the date the option was granted.

Stock Options.

The Company accounts for all stock-based compensation payments to employees and directors, including grants of employee stock options, at fair value at the date of grant and expenses the benefit in operating expense in the consolidated statements of operations over the service period of the awards. The Company records the expense for stock-based compensation awards subject to performance-based milestone vesting over the remaining service period when management determines that achievement of the milestone is probable based on the expected satisfaction of the performance conditions as of the reporting date. The Company records the expense for stock-based compensation awards subject to market-condition vesting over a derived service period which is calculated at the grant date. The fair value of each stock option granted is estimated on the date of grant using the Black-Scholes or other option pricing models, which requires various assumptions including estimating stock price volatility, expected life of the stock option, risk free interest rate and estimated forfeiture rate.

During the year ended December 31, 2025, the Company granted stock options to purchase up to 89,000 shares of common stock at a weighted average exercise price of $6.90. The stock options granted have either time-based or market-condition vesting.

The awards with time-based vesting have periods of up to four years and had grant date fair values between $5.24 and $17.56. The fair value was calculated using the Black-Scholes option pricing model and used the follow assumptions: risk free interest rates of 3.82% to 4.65%, based on the U.S. Treasury yield in effect at the time of grant; expected life of five to six years; and volatility of 121% to 128% based on historical volatility of the Company’s common stock over a time that is consistent with the expected life of the option.

The awards with market-condition vesting have a derived service period of 1.6 years and had a grant date fair value of $5.70. The fair value was calculated using a Monte Carlo Simulation and used the following assumptions: risk free interest rate of 4.67%; remaining term of ten years; and volatility of 121%.

On August 30, 2024, the Company’s board of directors (the “Board”) approved a one-time stock option repricing (the “Option Repricing”), effective August 31, 2024 (the “Effective Date”). The Option Repricing was undertaken in accordance with, and as permitted by the 2017 Plan. The Option Repricing applies to all Relevant Options (as defined below) granted pursuant to the 2017 Plan that were held by employees, including executive officers and non-employee directors of the Board, to the extent such options had an exercise price in excess of $6.56, the closing price per share of the Company’s Common Stock as reported on The Nasdaq Stock Market on August 30, 2024.  “Relevant Options” means all outstanding eligible stock options granted to eligible employees, service providers and non-employee directors of the board of the Company before and including December 31, 2022.  As of the Effective Date, all such options were repriced such that the exercise price per share was reduced to $6.56, provided that the original exercise price will apply to stock option exercises during a one year retention period. Under the terms of the Option Repricing, if prior to the first anniversary of the Effective Date (except following a change of control), a Relevant Option is exercised or employment/services are terminated by the Company with cause or voluntarily by the option holder, the option holder will be required to pay the original exercise price of the Relevant Option. If the employment/services of an option holder is terminated by the Company without cause prior to the first anniversary of the Effective Date, the option holder will retain the benefit of the reduced exercise price. The Option Repricing does not change the number of shares, the vesting schedule, or the expiration date of the Relevant Options.

Out of the Company’s approximately 304,000 total outstanding options on the Effective Date, approximately 177,000 were repriced. The Board approved the Option Repricing after careful consideration of various alternatives and the recommendation of the compensation committee of the Board that the repricing was fair, just, and reasonable to the Company and its stockholders. Management determined that the Option Repricing represented a modification of the impacted awards and calculated incremental compensation cost of approximately $0.5 million resulting from the modification. The incremental expense was recognized over 1.4 years.

As of December 31, 2025, there were 307,087 options that were vested or expected to vest with an aggregate intrinsic value of less than $4.8 million and a remaining weighted average contractual life of 6.2 years.

During the year ended December 31, 2024, there were 76,987 options granted with a weighted average exercise price of $5.01 and 5,799 options forfeited with a weighted average exercise price of $17.31.

Restricted Stock Awards.

Restricted stock awards are subject to vesting restrictions. If a grantee’s service with the Company is terminated prior to vesting of the restricted stock, all unvested shares shall be forfeited and returned to the Company. Upon vesting, the restricted stock award shall no longer be deemed restricted.

There were no restricted stock awards granted during the years ended December 31, 2025 and December 31, 2024, respectively. As of December 31, 2025 and 2024, respectively, there were no unvested restricted stock awards.

Stock Compensation.

During the years ended December 31, 2025 and 2024, we recorded compensation expense for all stock awards of $1.2 million and $1.5 million, respectively, within operating expense in the accompanying statements of operations. The 2025 and 2024 expense included approximately $0.3 million and $0.2 million, respectively, of expense related to the Option Repricing. As of December 31, 2025, the unrecognized compensation expense related to unvested stock awards was $0.6 million, which is expected to be recognized over a weighted-average period of 2.3 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.
