Share-Based Payment Arrangement [Abstract] |
Capital Stock, Stock Plans, Warrants and Stock Based Compensation | 6. Capital Stock, Stock Plans, Warrants and Stock Based Compensation The Company has certain stock option plans under which it may award incentive stock options (“ISOs”) and/or non-qualified stock options (“NQSOs”) to employees, officers, outside directors, and outside consultants. In connection with the appointment of Mr. Troy Eshleman to the position of Chief Operating Officer (“COO”) by the Company’s Board of Directors (the “Board”) on January 23, 2025 (see further information in “Note 13 – Executive Compensation” regarding this appointment), the Compensation and Stock Option Committee (the “Compensation Committee”) recommended, and the Board approved, the grant to Mr. Eshleman of an ISO for the purchase, under the Company’s 2017 Stock Option Plan (the “2017 Plan”), of up to 50,000 shares of the Company’s common stock, $.001 (the “Common Stock”). The ISO has a six-year6 term and vests at 20% per year over a five-year5 period, commencing on the first anniversary of the grant date. The exercise price of the ISO is $10.70 per share, which equals the closing price of the Company’s Common Stock as quoted on NASDAQ on the grant date. The following table summarizes stock-based compensation recognized for the three months ended March 31, 2025, and 2024 for our employee and director stock options.
