Share-Based Compensation |
Share-Based Compensation | 15. Share-Based Compensation ​ The Company accounts for share-based compensation under the provisions of ASC Topic 718 by using the fair value method for expensing stock options and stock awards. ​ Total share-based compensation expense was approximately $1,003,292, $1,336,000, and $345,000 for the fiscal years ended September 30, 2024, 2023 and 2022, respectively. Compensation expense related to share-based awards is recorded as a component of Cost of sales and selling, general and administrative expenses. ​ 2019 Stock-Based Incentive Compensation Plan ​ The 2019 Stock-Based Incentive Compensation Plan (the “2019 Plan”) was approved by the Company’s shareholders at the Company’s Annual Meeting of Shareholders held on April 2, 2019. The 2019 Plan authorizes the grant of stock appreciation rights, restricted stock, options and other equity-based awards. Options granted under the 2019 Plan may be either “incentive stock options” as defined in section 422 of the Code or nonqualified stock options, as determined by the Compensation Committee. ​ Subject to an adjustment necessary upon a stock dividend, recapitalization, forward split or reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase or share exchange, extraordinary or unusual cash distribution, or similar corporate transaction or event, the maximum number of shares of common stock available for awards under the 2019 Plan is 750,000, plus 139,691 shares of common stock that were authorized but unissued under the 2009 Plan as of the effective date of the 2019 Plan (i.e., April 2, 2019), all of which may be issued pursuant to awards of incentive stock options. ​ If any award is forfeited, terminates or otherwise is settled for any reason without an actual distribution of shares to the participant, the related shares of common stock subject to such award will again be available for future grant. Any shares tendered by a participant in payment of the exercise price of an option or the tax liability with respect to an award (including, in any case, shares withheld from any such award) will not be available for future grant under the 2019 Plan. If there is any change in the Company’s corporate capitalization, the Compensation Committee must proportionately and equitably adjust the number and kind of shares of common stock which may be issued in connection with future awards, the number and kind of shares of common stock covered by awards then outstanding under the 2019 Plan, the aggregate number and kind of shares of common stock available under the 2019 Plan, any applicable individual limits on the number of shares of common stock available for awards under the 2019 Plan, the exercise or grant price of any award, or if deemed appropriate, make provision for a cash payment with respect to any outstanding award. In addition, the Compensation Committee may make adjustments in the terms and conditions of any awards, including any performance goals, in recognition of unusual or nonrecurring events affecting the Company or any subsidiary, or in response to changes in applicable laws, regulations, or accounting principles. ​ Following is a summary of option activity under the 2019 Plan for the fiscal year ended September 30, 2024, and changes during the periods then ended: ​

​ Fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. Options are exercisable over a maximum term of ten years from date of grant and vest typically over periods of three to five years from the grant date. The expected term of options represents the period of time that options granted are expected to be outstanding and is based on historical experience and the expected turnover rate of the employees receiving the options. Expected volatility is based on historical volatility of the Company’s stock. The risk free interest rate is based on U.S. Treasuries with maturities consistent with the expected life of the options in effect at the time of grant. Compensation expense for employee stock options includes an estimate for forfeitures and is recognized ratably over the vesting term. ​ Below are the fair value assumptions used to record stock option compensation expense, related to the 2019 Plan, for the following periods identified: ​

​ The Company granted 161,613, 224,374 and 0 options in fiscal years ended 2024, 2023 and 2022, respectively. ​ Total compensation expense associated with stock option awards to employees under the 2019 Plan was approximately $301,000, $756,000 and $167,000 for fiscal years ended September 30, 2024, 2023 and 2022, respectively. ​ At September 30, 2024, unrecognized compensation expense of $ 495,797, net of forfeitures, related to non-vested stock options under the 2019 Plan, will be recognized. ​ Restricted Stock Units ​ During fiscal year 2024, the Company’s Board of Directors (the “Board”) approved grants of RSUs to the non-employee directors on the Board as compensation for their services from the beginning of calendar year 2024 to vest on the date of the Company’s 2024 Annual Meeting of Shareholders. After the 2024 Annual Meeting of Shareholders, the Board approved grants of RSUs to the non-employee directors on the Board as compensation for their services. Under the terms of the awards, the RSUs will vest on the first anniversary of the grant date. At the time of vesting, the RSUs will be settled in shares of the Company’s common stock at a rate of one share of stock for each unit, provided that, if a director resigns from the Board prior to the vesting date, such director shall only receive a pro rata portion of such award for time served. ​ During fiscal year 2024, the Board approved grants of RSUs to both the Chief Executive Officer, Chief Financial Officer and the former Chief Financial Officer. Certain RSUs to the Chief Executive Officer vested immediately, and the remainder will vest quarterly over a three-year period. The approved grants of the RSUs to the Chief Financial Officer will vest over a four-year period. The approved grants of the RSUs to the former Chief Financial Officer would have vested over a four-year period. On November 8, 2023, Michael Linacre, Chief Financial Officer of Innovative Solutions and Support, Inc., notified the Company of his resignation from all of his positions with the Company, effective immediately, which resulted in the forfeiture of 11,503 RSUs. ​ As of September 30, 2024, there were 242,080 restricted stock units outstanding under the 2019 Plan. As of September 30, 2023, and September 30, 2022 there were 101,968 and 32,897 respectively, unvested restricted stock units outstanding under the 2019 Plan. ​
