Stock-Based Compensation
The 2021 Plan allows the compensation committee of the Board to make equity-based and cash-based incentive awards to the Company’s officers, employees, directors and other key persons (including consultants). The number of shares reserved and available for issuance under the plan will automatically increase each January 1 by the lesser of 5% of the outstanding number of shares of Class A and Class B common stock on the immediately preceding December 31, or such lesser number of shares as determined by the compensation committee. This number is subject to adjustment in the event of a stock split, stock dividend or other change in the Company’s capitalization. In December 2025, the compensation committee of our board of directors approved no increase in the number of shares of Class A common stock reserved for issuance under the 2021 Plan on January 1, 2026.
The Company accounts for stock-based compensation in accordance with the provisions of ASC 718 Compensation - Stock Compensation, which requires the recognition of expense related to the fair value of stock-based compensation awards in the statements of operations. For stock option awards issued under the Company’s stock-based compensation plans to employees and members of the Board for their services on the Board, the fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model as discussed further below. For restricted stock units (“RSUs”) granted subject to service-based vesting conditions, and performance-based stock units (“PSUs”) with both service and performance conditions, the fair value is determined based on the closing price of the Company’s Class A common stock, as reported on the New York Stock Exchange. For PSUs with both service and performance conditions, this grant-date fair value is also impacted by the number of units that are expected to vest during the performance period and is adjusted through the related stock-based compensation expense at each reporting period based on the probability of achievement of that performance condition. If the Company determines that an award is unlikely to vest, any previously recorded stock-based compensation expense is reversed in the period of that determination. The grant date fair value of PSUs with both service and market conditions is calculated using a model to estimate the probability of satisfying the performance condition stipulated in the award grant, including the possibility that the market condition may not be satisfied.
Awards granted prior to January 1, 2024 subject to service-based vesting conditions generally vest over a four-year requisite service period. Awards granted after January 1, 2024 subject to service-based vesting conditions generally vest over a three-year requisite service period. For all other service-based awards, the Company recognizes compensation expense on a straight-line basis over the requisite service period of the award with actual forfeitures recognized as they occur.
The fair value of each option award was estimated on the date of grant using the Black-Scholes option-pricing model. The Company determined the expected volatility for options granted using an average of the historical volatility measures of a peer group of companies that issued options with substantially similar terms. The expected life of options granted to employees was calculated using the simplified method, which represents the average of the contractual term of the option and the weighted-average vesting period of the option. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected life of the share option. The Company has not paid, nor anticipates paying, cash dividends on its ordinary shares; therefore, the expected dividend yield is assumed to be zero.
The weighted-average assumptions utilized to determine the fair value of options granted to employees are presented in the following table:
| | | | | | | | | | | |
| Year Ended December 31, |
| 2024 | | 2023 |
| Expected volatility | 61.8 | % | | 63.1 | % |
| Weighted-average risk-free interest rate | 4.28 | % | | 3.75 | % |
| Expected dividend yield | — | | | — | |
| Expected life – in years | 6 | | 6 |
The Company did not grant options during the year ended December 31, 2025.
