In November 2016, the Company’s Board of Directors adopted the 2016 Stock Option and Grant Plan (“2016 Plan”) under which officers, employees, directors, consultants and other key persons of the Company or its affiliates may be granted incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock and restricted stock units. On August 10, 2021, the Company’s Board of Directors amended the 2016 Plan to provide that no new awards could be granted under the 2016 Plan.
Under the 2016 Plan, stock options were generally granted with an exercise price equal to the estimated fair value of the Company’s common stock, as determined by the Company’s Board of Directors on the date of grant. Options generally have contractual terms of ten years.
Outstanding options generally vest over six years, contain a one year cliff, are exercisable immediately and, upon early exercise, are subject to repurchase by the Company at the original exercise price. If an ISO is granted to an optionee who, at the time of grant, owns more than 10% of the voting power of all classes of capital stock, the term of the ISO is five years. Options issued under the 2016 Plan must be priced at no less than the fair value of the shares on the date of the grant provided, however, that the exercise price of an option granted to a 10% stockholder is not less than 110% of the fair value of the shares on the date of grant. The Board of Directors determines the exercisability provisions of a stock option agreement at its sole discretion.
The fair value of the RSU’s granted under the 2016 Plan was determined by the Company’s Board of Directors on the date of grant. Generally, RSUs granted under the 2016 Plan have a six year vesting period.
On August 10, 2021, the Company adopted the 2021 Equity Incentive Plan (“2021 Plan”). Under the 2021 Plan, the Company can grant incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units and performance awards to employees, directors and consultants. The number of shares available for issuance under the 2021 Plan will be increased on the first day of each fiscal year, beginning on January 1, 2022, in an amount equal to the lesser of (i) a number of shares equal to four percent (4%) of the total number of shares of all classes of common stock of the Company outstanding on the last day of the immediately preceding fiscal year, or (ii) such number of shares determined by the Company’s Board of Directors. On January 1, 2024, the number of shares available for issuance under 2021 plan increased by 27,930,481 shares.
The fair value of the RSU’s granted under the 2021 Plan was determined by the Company’s Board of Directors on the date of grant. Generally, RSUs granted under the 2021 Plan have a four year vesting period.
Restricted Stock Units
A summary of RSU activity for the three months ended March 31, 2024 is as follows (in thousands, except per share data):
The total fair value of RSUs vested for the three months ended March 31, 2024 and 2023 was $37.9 million and $26.7 million, respectively.
On February 27, 2023, the Company’s Compensation Committee of the Board of Directors (“Compensation Committee”) approved a performance-based bonus program under which RSUs were awarded in connection with the achievement of specified goals in 2023 (“2023 Bonus Plan”). The RSU awards were granted when the achievement of each goal was approved by the Compensation Committee in 2023, and the RSUs vested in equal installments in each of January, February, March and April 2024 provided the employee or consultant continued to be a service provider through the relevant vesting dates. The target bonus opportunity was equal to 30% of the employee’s base salary as of the applicable grant date, with stretch bonus goals that are one-third higher than the target amounts unless otherwise established by the Compensation Committee. In accordance with ASC 718 Compensation - Stock Compensation, awards under 2023 Bonus Plan were classified as a liability until such time that the respective milestones were met, at which point the liability was reclassified to equity. If it was determined that the milestone could not be met, the liability was reversed.
On February 12, 2024, the Compensation Committee approved a performance-based program under which RSUs are awarded. Each RSU represents the right to receive, upon vesting, up to 1.25 shares of the Company’s common stock, based on the achievement of certain specified objectives tied to five goals during 2024 (“2024 Bonus Plan”). Each goal has criteria for achievement of a minimum, target or maximum achievement level, expressed as a percentage, and the amount of the awards that will vest is calculated by summing the actual achievement percentages as of December 31, 2024. The maximum possible amount that will vest is 125%. If exactly the minimum or target levels are achieved, 45% and 100% of the awards, respectively, will vest. The RSUs awarded under the 2024 Bonus Plan will vest in equal installments on each of January 14, 2025, February 10, 2025, March 4, 2025 and April 7, 2025, subject in each case to the participant’s continued status as a service provider through respective vesting date. In accordance with ASC 718 Compensation - Stock Compensation, the Company has determined that 2024 Bonus Plan awards are equity awards with performance condition, and classified them as an equity.
The Company recorded stock-based compensation expense of $7.3 million and $3.3 million during the three months ended March 31, 2024 and 2023 in relation to 2024 Bonus Plan and 2023 Bonus Plan.
In June 2023, the Compensation Committee approved long-term incentive performance-based RSU awards (“LTI Awards”) to certain employees of the Company. The LTI Awards vest in a single installment on June 21, 2026, provided that (i) certain performance conditions are met on or prior to that date and (ii) the employee continues to be a service provider through the vesting date. The Company considers the probability of achieving each of the performance goals at the end of each reporting period and recognizes expense over the requisite service period when achievement of the goal is determined to be probable, and adjusts the expense if the probability of achieving the goal later changes.
On February 12, 2024, the Compensation Committee approved a long-term performance-based RSU awards (“LPA Awards”) to certain employees of the Company. The LPA Awards have the same performance conditions as the awards granted under the 2024 Bonus Plan and will vest in three equal annual installments on the anniversary of the grant date, provided that performance conditions are satisfied and the employee continues to be a service provider through the respective vesting dates. In accordance with ASC 718 Compensation - Stock Compensation, Management has determined that these LPA awards are equity awards with performance and service conditions, and classified them as an equity.
The Company recorded stock-based compensation expense of $1.5 million and nil during the three months ended March 31, 2024 and 2023, in relation to LPA and LTI awards.

Under the 2021 ESPP, participating employees may be offered the option to purchase shares of the Company’s Common Stock at a purchase price which equals 85% of the fair market value of the Company’s common stock on the enrollment date or on the exercise date, whichever is lower.
