Equity Incentive Plans
In July 2021, the Company adopted the 2021 Equity Incentive Plan (“2021 Plan”), which became effective on July 20, 2021. The 2021 Plan provides for the grant of incentive stock options (“ISOs”), within the meaning of Section 422 of the Code to employees, including employees of any parent or subsidiary, and for the grant of nonstatutory stock options (“NSOs”), stock appreciation rights, restricted stock awards (“RSAs”), performance-based restricted stock units (“PSUs”), restricted stock units (“RSUs”) and other forms of awards to the Company’s employees, directors and consultants, including employees and consultants of the Company’s affiliates. As of March 31, 2026, 6.5 million shares remained available for future issuance under the 2021 Plan. The Company recognized total stock-based compensation expense related to equity incentive awards of $5.4 million and $5.9 million for the three months ended March 31, 2026 and 2025, respectively.
Stock Options
Prior to becoming a public company in 2021, the Company granted options to employees, directors and consultants. The Company ceased granting options after its initial public offering in July 2021. Options were granted with an exercise price equal to the fair value of the shares on the date of grant. The maximum term of options granted under the plan is 10 years from the date of grant. Options generally vest according to a four-year vesting schedule, with 25% of the shares vesting on the first anniversary of the vesting commencement date and the remainder of the shares vesting in equal monthly installments thereafter.

Aggregate intrinsic value represents the difference between the Company’s fair value of its common stock and the exercise price of outstanding options. The aggregate intrinsic value of stock options exercised was nominal during each of the three months ended March 31, 2026 and 2025.
Restricted Stock Units and Performance-Based Restricted Stock Units
The fair value of RSUs and PSUs is determined using the closing market price of the Company’s common stock on the date of grant. The RSUs vest over the requisite service period, generally three years or four years, subject to the continuous service of the individual.
In February 2026 and 2025, the Company granted PSUs for 0.7 million shares and 0.9 million shares of common stock, respectively. The PSUs vest on the satisfaction of both service-based and performance-based conditions. The PSUs have a one-year performance period based on revenue and Adjusted EBITDA targets as well as non-quantitative business-related performance criteria that will determine the total vestable shares. After the applicable performance period, one-fourth of the
vestable shares will vest upon the Compensation Committee’s certification of the degree of achievement of the applicable goals, and the remaining vestable shares will vest over a three-year service period. In February 2026, it was determined that the Company substantially met the performance goals for the PSUs granted in 2025, and accordingly, these PSUs will vest at approximately 99% attainment. As of March 31, 2026, none of the PSUs granted in 2026 had vested, settled or cancelled. As of March 31, 2026, 0.1 million of the PSUs granted in 2025 had vested or settled and 0.5 million of the PSUs granted in 2025 were cancelled.

As of March 31, 2026, there was an estimated $37.4 million of total unrecognized stock-based compensation expense related to RSUs and PSUs with a weighted average remaining requisite service period of 2.32 years.

Employee Stock Purchase Plan
In June 2022, the Compensation Committee approved the terms of the Company’s offerings under its 2021 Employee Stock Purchase Plan (“ESPP”). Under the terms of the offering, the Company’s employees can elect to have up to 15% of their annual compensation, up to a maximum of $25,000 per year, withheld to purchase shares of the Company’s common stock for a purchase price equal to 85% of the lesser of the closing fair market value per share of the Company’s common stock on (i) the commencement date of the six-month offering period, or (ii) the respective purchase date. The initial offering period commenced on August 1, 2022 and ended on January 31, 2023 with subsequent six-month offering periods commencing on February 1st and August 1st of each year. The Company recognized a nominal amount of stock-based compensation expense for the ESPP during each of the three months ended March 31, 2026 and 2025. The Company distributed 0.1 million shares of the Company’s common stock through the ESPP in each of the three months ended March 31, 2026 and 2025.
