Share-based Compensation | Share-based Compensation Amended and Restated 2019 Equity Incentive Plan In July 2019, the Company’s board of directors (the “Board”), upon the recommendation of the compensation committee of the Board, adopted the 2019 Equity Incentive Plan (the “2019 Plan”), which was subsequently approved by the Company’s stockholders and was later amended and restated by the Board in January 2021. The Company initially reserved 52,000,000 shares of common stock for the issuance of awards under the 2019 Plan. The 2019 Plan provides that the number of shares reserved and available for issuance under the plan automatically increases each April 1, beginning on April 1, 2020, by 4% of the outstanding number of shares of the Company’s common stock on the immediately preceding March 31 or such lesser number determined by the compensation committee. This number is subject to adjustment in the event of a stock split, stock dividend or other change in the Company’s capitalization. As of December 31, 2023, 50,228,181 shares of common stock were available for future issuance under the 2019 Plan. Stock options The following table summarizes activity for stock options during the nine months ended December 31, 2023: Number of Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value (in thousands) (per share) (years) (in thousands) Balance, March 31, 2023 4,636 $ 22.25 6.5 $ 94,565 Exercised (1,188) 20.38 Forfeited or expired (67) 39.49 Balance, December 31, 2023 3,381 $ 22.57 5.8 $ 108,627 Options vested and expected to vest at December 31, 2023 3,381 $ 22.57 5.8 $ 108,627 Options vested and exercisable at December 31, 2023 3,162 $ 21.49 5.7 $ 104,987 As of December 31, 2023, the total unrecognized compensation expense related to non-vested stock options was $2.6 million and is expected to be recognized over a weighted average period of 0.6 years. The Company recognized $1.3 million and $4.6 million of share-based compensation expense related to stock options for the three months ended December 31, 2023 and 2022, respectively, and $7.0 million and $13.8 million of share-based compensation expense related to stock options for the nine months ended December 31, 2023 and 2022, respectively. Restricted shares and units The following table provides a summary of the changes in the number of restricted stock awards (“RSAs”) and restricted stock units (“RSUs”) for the nine months ended December 31, 2023: Number of Weighted Average Grant Date Fair Value Number of RSUs Weighted Average Grant Date Fair Value (in thousands) (per share) (in thousands) (per share) Balance, March 31, 2023 4 $ 16.00 8,836 $ 41.76 Granted — — 5,732 51.78 Vested (4) 16.00 (3,644) 40.43 Forfeited — — (589) 44.32 Balance, December 31, 2023 — $ — 10,335 $ 47.65 RSUs outstanding as of December 31, 2023 were comprised of 9.3 million RSUs with only service conditions and 1.0 million RSUs with both service and performance conditions (“PSUs”). During the nine months ended December 31, 2023, the Company granted PSUs to certain key employees that generally vest 33% one year after the grant date and the remaining 67% vest ratably on a quarterly basis over the following two years (the “Annual PSUs”). The number of shares that may be earned pursuant to the Annual PSUs is based on specific company metrics related to the Company’s fiscal year ending March 31, 2024. No Annual PSUs will be earned with respect to any metric if the applicable “threshold” percentage of the specific metric is not achieved, and the overall number of shares that may be earned shall not exceed 200% of the target award. Once the Annual PSUs are earned, they are then also subject to time-based vesting, with 33% of the earned Annual PSUs vesting on the first anniversary of the grant date, and with the remaining 67% vesting in eight equal quarterly installments over the following two years, and provided that the key employee remains employed by the Company through the applicable vesting date. As of December 31, 2023, the total unrecognized compensation expense related to unvested restricted stock units was $413.7 million and is to be recognized over a weighted average period of 2.2 years. The Company recognized $52.1 million and $29.0 million of share-based compensation expense related to restricted shares and units for the three months ended December 31, 2023 and 2022, respectively, and $141.4 million and $85.7 million of share-based compensation expense related to restricted shares and units for the nine months ended December 31, 2023 and 2022, respectively. Employee Stock Purchase Plan In July 2019, the Board adopted, and the Company’s stockholders approved, the 2019 Employee Stock Purchase Plan (“ESPP”). The Company offers, sells and issues shares of common stock under this ESPP from time to time based on various factors and conditions, although the Company is under no obligation to sell any shares under this ESPP. The ESPP provides for six-month offering periods and each offering period consists of six-month purchase periods. On each purchase date, eligible employees purchase shares of the Company’s common stock at a price per share equal to 85% of the lesser of (1) the fair market value of the Company’s common stock on the offering date or (2) the fair market value of the Company’s common stock on the purchase date. For the nine months ended December 31, 2023, 534,022 shares of common stock were purchased under the ESPP. As of December 31, 2023, 15,864,787 shares of common stock were available for future issuance under the ESPP. As of December 31, 2023, there was $2.9 million of unrecognized share-based compensation related to the ESPP that is expected to be recognized over the remaining term of the current offering period. The Company recognized $1.5 million and $1.9 million of share-based compensation expense related to the ESPP for the three months ended December 31, 2023 and 2022, respectively, and $4.9 million and $5.4 million of share-based compensation expense related to the ESPP for the nine months ended December 31, 2023 and 2022, respectively.
