For the years ended April 30, 2025, 2024 and 2023, the Company recorded stock-based compensation expense of approximately $21,461,000, $17,069,000 and $10,765,000, respectively.

On September 24, 2021, the stockholders of the Company approved the 2021 Equity Incentive Plan (“2021 Plan”) effective September 24, 2021, for officers, directors, key employees and consultants. Under the 2021 Plan, incentive stock options, nonqualified stock options, restricted stock awards, stock appreciation right awards, performance

share awards, performance stock unit awards, dividend equivalents awards, stock payment awards, deferred stock awards, restricted stock unit awards, other stock-based awards, performance bonus awards or performance-based awards may be granted at the discretion of the compensation committee, which consists of outside directors. The sum of any cash compensation, or other compensation, and the value of awards granted to a non-employee director as compensation for services as a non-employee director during any fiscal year may not exceed $500,000, which amount is increased to $700,000 in the fiscal year of a non-employee director’s initial year of service as a non-employee director. The exercise price for any incentive stock option shall not be less than 100% of the fair market value on the date of grant. Vesting of awards is established at the time of grant.

On January 14, 2007, the stockholders of the Company approved the 2006 Equity Incentive Plan (“2006 Plan”) effective January 21, 2007, for officers, directors, key employees and consultants. On September 29, 2011, the stockholders of the Company approved an amendment and restatement of the 2006 Plan (“Restated 2006 Plan”). Under the Restated 2006 Plan, incentive stock options, nonqualified stock options, restricted stock awards, stock appreciation right awards, performance share awards, performance stock unit awards, dividend equivalents awards, stock payment awards, deferred stock awards, restricted stock unit awards, other stock-based awards, performance bonus awards or performance-based awards may be granted at the discretion of the compensation committee, which consists of outside directors. A maximum of 4,884,157 shares of stock may be issued pursuant to awards under the Restated 2006 Plan. The maximum number of shares of common stock with respect to one or more awards that may be granted to any one participant during any twelve month period is 2,000,000. A maximum of $5,000,000 may be paid in cash to any one participant as a performance-based award during any twelve month period. The exercise price for any incentive stock option shall not be less than 100% of the fair market value on the date of grant. Vesting of awards is established at the time of grant. The Restated 2006 Plan expired in July 2021.

On September 19, 2023, the stockholders of the Company approved the Company’s 2023 Employee Stock Purchase Plan (the “2023 ESPP”). The 2023 ESPP allows for eligible employees to purchase common stock through payroll deductions of up to $25,000 worth of common stock (determined at the fair market value of the shares at the time such rights are granted) for each calendar year in which the purchase rights are outstanding at any time. Shares of common stock are purchased under the 2023 ESPP at a discount to the market price of the shares of no less than 85% of the fair market value of the Company’s common stock on each purchase date. Subject to adjustments for changes in the Company’s capitalization and certain corporate transactions, the total number of shares available for issuance under the 2023 ESPP is 1,000,000 shares of common stock. As of April 30, 2025, 14,598 shares have been issued under the 2023 ESPP.

The fair value of the grants under the 2023 ESPP was estimated at the grant date using an option pricing model. Assumptions included in the option pricing model included the expected term of grants, the expected volatility, the risk-free interest rate, and the expected dividend yield. The expected term of stock options represents the weighted average period the Company expects the grants to remain outstanding, based on the offering period of the grant. The expected volatility is based on historical volatility for the Company’s stock. The risk-free interest rate is based on the implied yield on a U.S. Treasury zero coupon bond with a remaining term that approximates the expected term of the option. The expected dividend yield of zero reflects that the Company has not paid any cash dividends since inception and does not anticipate paying cash dividends in the foreseeable future.

The fair value of stock options granted previously was estimated at the grant date using the Black-Scholes option pricing model. Assumptions included in the Black-Scholes option pricing model included the expected term of stock options, the expected volatility, the risk-free interest rate, and the expected dividend yield. The expected term of stock options represents the weighted average period the Company expects the stock options to remain outstanding, based on the Company’s historical exercise and post-vesting cancellation experience and the remaining contractual life of its outstanding options. The expected volatility is based on historical volatility for the Company’s stock. The risk-free interest rate is based on the implied yield on a U.S. Treasury zero-coupon bond with a remaining term that approximates the expected term of the option. The expected dividend yield of zero reflects that the Company has not paid any cash dividends since inception and does not anticipate paying cash dividends in the foreseeable future.
