The Company has adopted its 2017 Equity Incentive Plan, as amended and restated (the “Plan”), which permits the issuance of up to 10,000,000 shares of Class A common stock, which may be granted as incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, performance stock, restricted stock units or performance stock units. Awards under the Plan generally vest over four to five years, with options expiring not more than ten years from the date of grant, three months after termination of employment or one year after the date of death or termination due to disability of the grantee. As of March 31, 2026, there were 6,057,616 shares of Class A common stock available to grant under the Plan. Pursuant to the terms of the Plan, awards may not be granted after September 5, 2034.

The Company has adopted its Employee Share Purchase Plan, as amended (“ESPP”), which permits eligible employees to elect to purchase the Company’s Class A common stock via paycheck deductions. The purchase price is 85% of the closing price of the Company’s Class A common stock on the last trading day of each offering period, which begins the first day of each fiscal quarter and ends on the last day of that fiscal quarter. The Company’s initial offering period started January 1, 2019. At inception, there were 1,000,000 shares available for purchase through the ESPP and 805,511 shares were available as of March 31, 2026.

Holders of restricted stock have all of the rights of a stockholder with respect to such shares, including the right to vote the shares but not the right to receive dividends or other distributions. Substantially all of the awards vest over four years in equal annual installments. On each vesting date, the related employee tax liabilities are either paid in cash by the employee or stock is sold back to the Company at the then-current fair

value to offset the required minimum tax withholding obligations. Forfeitures are recognized as they occur. Compensation expense related to the awards is recognized ratably each month over the vesting period.

The Company grants performance stock awards to certain employees that are subject to both a market based vesting and a service-based vesting condition (“Performance Awards”). Holders of Performance Awards do not participate in dividends until both their market-based and service-based vesting requirements have been met. Due to the existence of the service requirements on Performance Awards, compensation expense is recognized ratably over the respective minimum service periods from the grant date through the vesting date. The fair values of Performance Awards are based on a Monte Carlo simulation valuation model.

The Performance Awards granted on September 16, 2025 will vest based upon (i) achieving a compound annual growth rate of total shareholder return of at least 8% as of September 16, 2030 and (ii) continued employment through September 16, 2030.

Below is a summary of the grant date fair value based on the Monte Carlo simulation valuation model and the significant assumptions used to estimate the grant date fair value of the Performance Awards granted September 16, 2025:
