Stock-Based Compensation
Plans and Awards
The Company’s eligible employees participate in various stock-based compensation plans, which are provided by the Company directly.
In August 2021, the Board of Directors approved the 2021 Incentive Award Plan (the “2021 Plan”), which became effective on September 28, 2021. The Company no longer grants equity awards under its 2010 Equity Incentive Plan, 2011 Stock Plan, 2012 Milestone Stock Plan, or 2019 Founder Stock Plan (collectively, the “Prior Plans”, and together with the 2021 Plan, the “Plans”), and shares available for issuance under the Prior Plans were made available for issuance under the 2021 Plan. The shares authorized under the 2021 Plan will increase annually, beginning on January 1, 2022 and continuing through 2031, by the lesser of (i) 5% of the Company’s outstanding common stock (on an as converted basis) as of the last day of the immediately preceding fiscal year, or (ii) a smaller amount as agreed by the Board of Directors. Awards granted under the 2021 Plan generally vest over four years. In addition, the shares authorized under the 2021 Plan will increase, among other things, to the extent that an award (including an award under the Prior Plans) terminates, expires, or lapses for any reason or an award is settled in cash without the delivery of shares.
In January 2025, the shares authorized for issuance under the 2021 Plan automatically increased by 6,036 shares, and 29,659 shares remained available for future issuance pursuant to new awards as of December 31, 2025.
The Company issues previously unissued shares upon the exercise of stock options or settlement of RSUs or PSUs.
Employee Stock Purchase Plan
In August 2021, the Board of Directors adopted and the stockholders of the Company approved the 2021 Employee Stock Purchase Plan (the “ESPP”). The shares authorized under the ESPP will increase annually, beginning on January 1, 2022 and continuing through 2031, by the lesser of (i) 1% of the Company’s outstanding common stock (on an as converted basis) as of the last day of the immediately preceding fiscal year and (ii) a smaller amount as agreed by the Board of Directors; provided, however, no more than 16,615 shares of common stock may be issued under the ESPP.
In January 2025, the shares authorized for issuance under the ESPP automatically increased by 1,207 shares, and there were 6,124 shares available for future issuance pursuant to ESPP purchases as of December 31, 2025.

RSUs granted prior to the Company’s direct listing vest upon the satisfaction of both a service and a performance condition, which was satisfied upon the Company’s direct listing on September 20, 2021, and the Company recognizes stock-based compensation expense using the accelerated attribution method as the service conditions are met. RSUs granted after the Company’s direct listing only contain a service condition and are recognized on a straight line basis over the vesting period.
2025 Founders Grant
In March 2025, the Company granted 236 PSUs and 236 RSUs for Class A common stock to the Co-CEOs, in the aggregate, under the 2021 Plan (the “2025 Founders Grant”). The RSUs vest in equal monthly installments over a period of three years, beginning on January 1, 2025, subject to the Co-CEOs’ continued employment with the Company through the applicable vesting date. Vesting of the PSUs will occur after the end of the performance period, which began on January 1, 2025 and ends on the earlier of a change of control or December 31, 2027, in each case based on the Company’s total shareholder return (“TSR”) relative to the total shareholder returns of the companies in the Russell 2000 Growth Index as defined in the PSU agreement. The number of shares of Class A common stock to be issued in respect of the PSUs
that become vested is based on an achievement factor as set forth in the table below. The final settlement of the PSUs is subject to the Co-CEOs’ continued employment with the Company through the earlier of a change of control or December 31, 2027.
| | | | | | | | |
| Company TSR rank versus the companies in the Russell 2000 Growth Index | | Shares per PSU |
| Zero through 24th percentile | | — | |
| 25th through 49th percentile | | 0.5 | |
| 50th through 74th percentile | | 1.0 | |
| 75th or higher percentile | | 2.0 | |
The Company used a Monte Carlo simulation to calculate the grant date fair value of the PSUs of $9.6 million. The PSUs contain a single vesting tranche and expense will be recognized on a straight-line basis over the performance period. The grant-date fair value of the RSUs is $5.7 million which will be recognized on a straight-line basis over the service period.
2021 Founders Grant
In June 2021, the Company granted 4,398 PSUs and 1,885 RSUs to the Co-CEOs, in the aggregate, under the 2019 Plan (the “2021 Founders Grant”). The PSUs had a grant date fair value of $128.8 million, as determined by a Monte Carlo simulation, and vest in eight equal tranches upon the satisfaction of two performance conditions, (i) a qualified public offering, which was satisfied upon the Company’s direct listing in September 2021, and (ii) the price of the Company’s Class A common stock reaches stock price hurdles, ranging from $47.75 to $103.46, over a period of ten years, as defined by the terms of the award. If the PSUs vest, the Company will deliver one share of Class B common stock for each PSU on the settlement date, and unvested PSUs expire in June 2031. The RSUs had a grant date fair value of $66.9 million, and will vest in equal monthly installments over a period of five years. Vesting of the PSUs and RSUs are subject to the Co-CEOs continued employment with the Company through the applicable vesting dates. Shares underlying vested 2021 Founders Grant PSUs and RSUs will be issued to the Co-CEOs on a specified quarterly date following the second anniversary of the vesting date, except for an amount necessary to cover any taxes due in connection with the vesting, which will be withheld or sold to cover, or issued to offset, such taxes.
