EQUITY INCENTIVE PLAN [Abstract] |
EQUITY INCENTIVE PLAN | 9. 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 320,699 at September 30, 2024, of which 14,705 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 nine months ended September 30, 2024, the shares authorized for issuance increased by 71,006 shares. 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 condensed 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 fair value of each stock option granted is estimated on the date of grant using the Black-Scholes option pricing model, 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 nine months ended September 30, 2024, the Company granted stock options to purchase up to 75,862 shares of common stock at a weighted average exercise price of $4.99 per share. These awards have vesting periods of up to four years and had a weighted average grant date fair value of $4.54. The fair value calculation of options granted during the nine months ended September 30, 2024 used the following assumptions: risk free interest rate of 3.94% to 4.26%, based on the U.S. Treasury yield in effect at the time of grant; expected life of six years; and volatility of 133% to 139% based on historical volatility of the Company’s common stock over a time that is consistent with the expected life of the option. 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 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 represents a modification of the impacted awards and calculated incremental compensation cost of approximately $0.5 million resulting from the modification. The incremental expense will be recognized over 1.4 years. ​ The following table summarizes stock option activity under our plans during the nine months ended September 30, 2024:
​ | ​ | ​ | ​ | ​ | ​
​ |  | Number of |  | Weighted-Average
​ | ​ | Options | ​ | Exercise Price
Outstanding at January 1, 2024 |  | 232,744 | ​ | $ | 46.56
Granted |  | 75,862 | ​ |  | 4.99
Forfeited |  | (5,173) | ​ |  | 18.26
Outstanding at September 30, 2024 |  | 303,433 | ​ | $ | 7.19
Exercisable at September 30, 2024 |  | 187,554 | ​ | $ | 7.52
​ As of September 30, 2024, there were 274,463 options that were vested or expected to vest with aggregate intrinsic value of $0.1 million and a remaining weighted average contractual life of 6.8 years. 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. As of September 30, 2024, there were 2,492 and zero restricted stock awards that were vested and unvested, respectively. There were no restricted stock awards granted during the three and nine months ended September 30, 2024. There were 2,492 restricted stock awards granted during the three and nine months ended September 30, 2023, respectively. Stock Compensation. For the three and nine months ended September 30, 2024, we recorded non-cash stock-based compensation expense for all stock awards of $0.4 million and $1.1 million, respectively, within operating expense in the accompanying statements of operations. For the three and nine months ended September 30, 2023, we recorded non-cash stock-based compensation expense for all stock awards of $0.4 million and $1.2 million, respectively, within operating expense in the accompanying statements of operations. As of September 30, 2024, the unrecognized compensation expense related to unvested stock awards and the Option Repricing was $1.9 million, which is expected to be recognized over a weighted-average period of 1.7 years.
