13. Stock-Based Compensation

The 2014 Plan

Under the 2014 Stock Option Plan of Hotshine Holdings, Inc. (the “2014 Plan”), we may grant incentive stock options or nonqualified stock options to purchase shares of our common stock to our employees, directors, officers, outside advisors and non-employee consultants.

All stock options granted under the 2014 Plan are equity-classified and have a contractual life of ten years. Under the 2014 Plan, 60% of the shares in a grant contain service-based vesting conditions and vest ratably over a five-year period and 40% of the shares in a grant contain performance-based vesting conditions (“Performance Vesting Options”). The condition for the Performance Vesting Options is a change in control or an initial public offering, where (i) 50% of the Performance Vesting Options vest and become exercisable if the Principal Stockholders receive the Target Proceeds at the Measurement Date and (ii) the remaining 50% of the Performance Vesting Options vest and become exercisable if the Principal Stockholders receive the Maximum Amount at the Measurement Date. In June 2021, we modified all outstanding shares of Performance Vesting Options to remove, subject to the successful completion of the IPO, the requirement that the Principal Stockholders receive the Target Proceeds and the Maximum Amount as conditions for the Performance Vesting Options to vest. The exercise prices for stock options granted under the 2014 Plan were not less than the fair market value of the common stock of the Company on the date of grant. For the avoidance of doubt, the IPO constituted a performance measurement date under the applicable option agreements for the Performance Vesting Options and the Performance Vesting Options vested in full in connection with the IPO.

The 2021 Plan

In June 2021, the Board adopted the 2021 Incentive Award Plan (the “2021 Plan”), which was subsequently approved by our stockholders and became effective on June 25, 2021. Under the 2021 Plan, we may grant incentive stock options, nonqualified stock options, restricted stock units ("RSUs"), restricted stock, and other stock- or cash-based awards to our employees, directors, officers, and non-employee consultants. Initially, the maximum number of shares of our common stock that may be issued under the 2021 Plan is 29,800,000 new shares of common stock, which includes 256,431 shares of common stock that remained available for issuance under the 2014 Plan at June 25, 2021. In connection with the IPO, stock option and RSU awards were granted with respect to 3,726,305 shares. Any shares of common stock subject to outstanding stock awards granted under the 2014 Plan and, following June 25, 2021, terminate, expire or are otherwise forfeited, reacquired or withheld will become available for issuance under the 2021 Plan.

All stock options granted under the 2021 Plan are equity-classified and have a contractual life of ten years. Under the 2021 Plan, the stock options contain service-based vesting conditions and generally vest ratably over a three- or five-year period (collectively with stock options under the 2014 Plan, the “Time Vesting Options”). The exercise prices for stock options granted under the 2021 Plan were not less than the fair market value of the common stock of the Company on the date of grant.

RSUs granted under the 2021 Plan are equity-classified and contain service-based conditions and generally vest ratably over one- to five-year periods. Each RSU represents the right to receive one share of our common stock upon vesting. The fair value is calculated based upon our closing stock price on the date of grant, and the stock-based compensation expense is recognized over the requisite service period, which is generally the vesting period.

 

The 2014 Plan and 2021 Plan are administered by the Board or, at the discretion of the Board, by a committee thereof. The exercise prices for stock options, the vesting of awards, and other restrictions are determined at the discretion of the Board, or its committee if so delegated.

The 2021 ESPP

In June 2021, the Board adopted the 2021 Employee Stock Purchase Plan (“2021 ESPP”), which was subsequently approved by our stockholders and became effective in June 2021. The 2021 ESPP authorizes the initial issuance of up to 5,000,000 shares of our common stock to eligible employees of the Company or, as designated by the Board, employees of a related company. The 2021 ESPP provides for offering periods not to exceed 27 months, and each offering period will include purchase periods. We determined that offering periods would commence at approximately the six-month period beginning with an enrollment date and ending with the next exercise date, except that the first offering period commenced on the effective date of our registration statement and ended on November 9, 2021.

 

The 2021 ESPP provides that the number of shares reserved and available for issuance under the 2021 ESPP will automatically increase on January 1 of each calendar year from January 1, 2022 through January 1, 2031 by an amount equal to the lesser of (i) 0.5% of the outstanding number of shares of common stock on the immediately preceding December 31 and (ii) such lesser number of shares of common stock as determined by the Board. The number of shares reserved and available for issuance under the 2021 ESPP as of January 1, 2023 is 7,322,350.

 

Share-Based Payment Valuation

The grant date fair value of Time Vesting Options granted is determined using the Black-Scholes option-pricing model. The grant date fair value of Performance Vesting Options is determined using a Monte Carlo simulation model and a barrier-adjusted Black-Scholes option-pricing model. The grant date fair value of stock purchase rights granted under the 2021 ESPP is determined using the Black-Scholes option-pricing model.

Stock-Based Compensation Expense

We estimated a forfeiture rate of 8.82% for awards with service-based vesting conditions based on historical experience and future expectations of the vesting of these share-based payments. We used this rate as an assumption in calculating stock-based compensation expense for Time Vesting Options, RSUs, and stock purchase rights granted under the 2021 ESPP.
