Stock-Based Compensation Plans
K – Stock-Based Compensation Plans
The Company has stock-based compensation plans under which awards of non-qualified stock options, incentive stock options and restricted stock have been or may be granted to employees, directors and certain advisors of the Company. The stock-based compensation plan being utilized at April 30, 2025 is the 2024 Equity Incentive Plan. The 2024 Equity Incentive Plan was approved by the Company’s shareholders and became effective on August 27, 2024. This plan governs all new equity-based awards granted on or after its effective date. The 2024 Equity Incentive Plan includes a reserve of 500,000 shares authorized for issuance of awards under the plan. At April 30, 2025, a total of 426,258 shares remained available for future awards under the 2024 Equity Incentive Plan. The Company recorded total stock-based compensation expense for all plans of approximately $4.7 million ($3.7 million after tax effects), $3.7 million ($2.9 million after tax effects), $5.3 million ($4.1 million after tax effects) for the years ended April 30, 2025, 2024, and 2023, respectively. Tax benefits were recognized for these costs at the Company’s overall effective tax rate, excluding discrete income tax benefits related to excess benefits on share-based compensation.
Stock Option Awards
The Company has options outstanding under the Amended and Restated Stock Option Plan. The shareholders of the Company approved the Amended and Restated Stock Option Plan (the “Restated Option Plan”) on August 5, 2015, which extended the term of the Stock Option Plan to June 10, 2025 and increased the number of shares of common stock reserved for issuance under the plan by an additional 300,000 shares to 1,800,000 shares. On August 29, 2018, August 26, 2020, and August 30, 2022, the shareholders of the Company approved amendments to the Restated Option Plan increasing the number of shares of common stock reserved for issuance under the plan by an additional 200,000, 200,000, and 185,000 shares, respectively. At April 30, 2025, a total of 434,567 shares of common stock are reserved for issuance of outstanding stock options under the Restated Option Plan. Options outstanding under the Restated Option Plan expire in the calendar years 2025 through 2034. As of April 30, 2025, there were 254,600 unvested options under the Restated Option Plan. No further awards may be granted under the Restated Option Plan.
The 2024 Equity Incentive Plan, which replaced the Restated Option Plan, provides for the grant of options to purchase shares of the Company’s common stock to employees, directors and certain advisors of the Company at a price not less than the fair market value of the stock on the date of grant and for periods not to exceed ten years. As of April 30, 2025, there were 2,500 unvested options under the 2024 Equity Incentive Plan.

The expected term of the options is based on evaluations of historical and expected future employee exercise behavior. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life at the grant date. Volatility is based on the historical volatility of the Company’s common stock. The Company has not historically issued any dividends and does not expect to do so in the foreseeable future.
There were 22,281 options granted during fiscal 2025, 197,486 granted during fiscal 2024, and 140,000 granted during fiscal 2023 under the Restated Option Plan, respectively. There were 7,500 options granted during fiscal 2025 under the 2024 Equity Incentive Plan. The grant-date fair value of options granted during fiscal 2025, 2024, and 2023 was $542,000, $5.7 million, and $5.1 million, respectively. The options were granted at fair market value on the date of grant. Generally, options vest after three to five years.
