2021 Equity Incentive Plan
In connection with the IPO and effective October 6, 2021, we adopted the 2021 Incentive Award Plan (the “2021 Equity Plan”), under which we may grant cash and equity-based incentive awards to our employees, consultants and directors. The maximum number of shares of our common stock available for issuance under the 2021 Equity Plan is equal to the sum of (i) approximately 14.5 million shares of our common stock, (ii) an annual increase on the first day of each year beginning in 2022 and ending in and including 2031, equal to the lesser of (A) 4% of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year and (B) such lesser amount as determined by our board of directors, and (iii) the approximately 1.0 million shares of our common stock that were available for issuance under the 2015 Equity Plan as of October 6, 2021. Effective January 1, 2022, the number of shares of our common stock available for issuance under the 2021 Equity Plan increased by approximately 7.7 million shares pursuant to the evergreen feature described in part (ii) of the immediately preceding sentence. Additionally, the number of shares of our common stock available for issuance under the 2021 Equity Plan may increase with respect to awards under the 2015 Equity Plan and any other prior equity incentive plans of the Company or its predecessor which are forfeited or lapse unexercised and which following the effective date of the 2021 Equity Plan are not issued under such prior plan; provided, however, no more than 14.5 million shares may be issued upon the exercise of incentive stock options. The share reserve formula under the 2021 Equity Plan is intended to provide us with the continuing ability to grant equity awards to eligible employees, directors and consultants for the ten-year term of the 2021 Equity Plan.
As of September 30, 2022, approximately 19.1 million shares were available for future awards to employees and other eligible participants under the 2021 Equity Plan.
2021 Employee Stock Purchase Plan
In connection with the IPO and effective October 6, 2021, we adopted the 2021 Employee Stock Purchase Plan (the “ESPP”). The ESPP is designed to allow our eligible employees to purchase shares of our common stock, at periodic intervals, with their accumulated payroll deductions. The ESPP consists of two components: an Internal Revenue Service (“IRS”) Code section 423 (“Section 423”) component, which is intended to qualify under Section 423 of the IRS Code and a non-Section 423 component, which need not qualify under Section 423 of the IRS Code. The aggregate number of shares of our common stock that has initially been reserved for issuance under the ESPP is equal to (i) approximately 2.9 million shares of our common stock, and (ii) an annual increase on the first day of each year beginning in 2022 and ending in and including 2031, equal to the lesser of (A) 1% of the aggregate number of shares of our common stock outstanding on the final day of the immediately preceding calendar year and (B) such smaller number of our shares of common stock as determined by our board of directors; provided that in no event will more than 29.0 million shares of our common stock be available for issuance under the Section 423 component of the ESPP. Our board of directors determined that no additional shares would become available under the ESPP as of January 1, 2022 pursuant to the evergreen feature described in part (ii) of the immediately preceding sentence. Our board of directors or the compensation committee will have authority to interpret the terms of the ESPP and determine eligibility of participants.
The ESPP will permit participants to purchase common stock through payroll deductions of up to 15% of their eligible compensation, which includes a participant’s gross base compensation for services to us. On the first trading day of each offering period, each participant will automatically be granted an option to purchase shares of our common stock. The option will expire at the end of the applicable offering period and will be exercised on each purchase date during such offering period to the extent of the payroll deductions accumulated during the offering period. We expect to have consecutive offering periods of approximately six months in length commencing on each June 1 and December 1 during the term of the ESPP. The purchase price for a share of our common stock will be 90% of the fair market value of a share on the enrollment date for such offering period or on the purchase date, whichever is lower, and subject to adjustment by our board of directors or compensation committee. Participants may voluntarily end their participation in the ESPP prior to the end of the applicable offering period and will be paid their accrued payroll deductions that have not yet been used to purchase shares of common stock. Upon exercise, the participant will purchase the number of whole shares that his or her accumulated payroll deductions will buy at the option purchase price, subject to the certain participation limitations. Participation will end automatically upon a participant’s termination of employment. No offering periods commenced under the ESPP during the three and nine months ended September 30, 2022.
Stock Options
During the nine months ended September 30, 2022, the Company granted approximately 1.0 million stock option awards under the 2021 Equity Plan. These options have a 10-year contractual term from the date of grant and vest in four ratable annual installments on each of the first four anniversaries of the grant date, subject to continuous employment or service from the grant date through the applicable vesting date. The exercise price associated with each of these awards is not less than the fair market value per share of our common stock at the time of grant. The fair value of the options granted during the nine months ended September 30, 2022 was calculated using the Black-Scholes option pricing model. Approximately 0.2 million and 0.3 million of stock options were exercised during the three and nine months ended September 30, 2022, respectively. No stock options were exercised during the three and nine months ended September 30, 2021. As of September 30, 2022, options to purchase approximately 25.1 million shares of our common stock were outstanding, of which approximately 21.8 million were exercisable.
Share-based compensation expense associated with stock options for the three months ended September 30, 2022 was $2.7 million, of which $0.2 million, $2.4 million and $0.1 million is included in Center operations, General, administrative and marketing and Other operating (income) expense, respectively, in our condensed consolidated statements of operations. Share-based compensation expense associated with stock options for the nine months ended September 30, 2022 was $17.4 million, of which $1.5 million, $15.4 million and $0.5 million is included in Center operations, General, administrative and marketing and Other operating (income) expense, respectively, in our condensed consolidated statements of operations. No share-based compensation expense related to stock options was recognized during the three and nine months ended September 30, 2021. As of September 30, 2022, unrecognized share-based compensation expense related to stock options was approximately $20.1 million, which is expected to be recognized over a weighted average remaining period of 2.9 years.
Restricted Stock Units
During the nine months ended September 30, 2022, the Company granted approximately 1.6 million restricted stock unit awards under the 2021 Equity Plan, of which approximately 1.3 million are time vesting awards and approximately 0.3 million are time vesting awards with a performance qualifier. Of the 1.6 million restricted stock unit awards that were granted during the nine months ended September 30, 2022, approximately 1.5 million vest in four ratable annual installments, approximately 0.1 million vest in two ratable annual installments and less than 0.1 million vest in approximately one annual installment, in each case subject to continuous employment or service from the grant date through the applicable vesting date. The majority of the awards that vest in two ratable annual installments were granted to executives as part of their incentive compensation for 2021, which had been recognized as an accrued compensation liability at December 31, 2021. The fair value of these restricted stock unit awards issued to executives was approximately $0.5 million. Accordingly, effective with the grant date associated with these restricted stock units, we recognized a $0.5 million decrease in Accrued expenses and other current liabilities and a $0.5 million increase in Additional paid-in capital on our condensed consolidated balance sheets. At September 30, 2022, approximately 2.8 million restricted stock units were outstanding.
Share-based compensation expense associated with restricted stock units for the three months ended September 30, 2022 was $3.1 million, of which $0.4 million, $2.6 million and $0.1 million is included in Center operations, General, administrative and marketing and Other operating (income) expense, respectively, in our condensed consolidated statements of operations. Share-based compensation expense associated with restricted stock units for the nine months ended September 30, 2022 was $10.8 million, of which $0.9 million, $9.7 million and $0.2 million is included in Center
operations, General, administrative and marketing and Other operating (income) expense, respectively, in our condensed consolidated statements of operations. Share-based compensation expense associated with restricted stock units for the three months ended September 30, 2021 was $1.8 million, all of which is included in General, administrative and marketing in our condensed consolidated statements of operations. Share-based compensation expense associated with restricted stock units for the nine months ended September 30, 2021 was $2.9 million, all of which is included in General, administrative and marketing in our condensed consolidated statements of operations. As of September 30, 2022, unrecognized share-based compensation expense related to restricted stock units was approximately $35.3 million, which is expected to be recognized over a weighted average remaining period of 3.1 years.
Restricted Series A Preferred Stock
Share-based compensation expense associated with a restricted Series A convertible participating preferred stock (“Series A Preferred Stock”) award for the three and nine months ended September 30, 2021 was $2.3 million and $4.0 million, respectively, all of which is included in General, administrative and marketing in our condensed consolidated statements of operations. Upon the consummation of the IPO, the shares of restricted Series A Preferred Stock associated with this award automatically converted into shares of restricted common stock. As of the conversion date, all share-based compensation expense related to this award of restricted Series A Preferred Stock had been recognized. No share-based compensation expense related to restricted Series A Preferred Stock was recognized during the three and nine months ended September 30, 2022.
Restricted Common Stock
Share-based compensation expense associated with the shares of restricted common stock that were issued upon the automatic conversion of the restricted Series A Preferred Stock, as noted immediately above in “—Restricted Series A Preferred Stock,” for the nine months ended September 30, 2022 was $5.0 million, all of which is included in General, administrative and marketing in our condensed consolidated statements of operations. These restricted shares were fully vested as of April 4, 2022, and there is no unrecognized share-based compensation expense related to these shares. No share-based compensation expense related to restricted common stock was recognized during the three and nine months ended September 30, 2021.
