In July 2019, the Company’s board of directors (the “Board”), upon the recommendation of the compensation committee of the board of directors, adopted the 2019 Equity Incentive Plan, as amended and restated (the “2019 Plan”) which was subsequently approved by the Company’s shareholders and was later amended and restated by the Board in January 2021.

The Company initially reserved 52,000,000 shares of common stock, or the Initial Limit, 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 will automatically increase 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, 2022, 43,823,732 shares of common stock were available for future issuance under the 2019 Plan.

During the nine months ended December 31, 2022, 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, 2023. 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 150% 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 executive officer remains employed by the Company through the applicable vesting date.

In July 2019, the Board adopted, and the Company’s shareholders approved, the 2019 Employee Stock Purchase Plan (“ESPP”). The Company expects to offer, sell and issue 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 will consist of six-month purchase periods. On each purchase date, eligible employees will 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, 2022, 553,188 shares of common stock were purchased under the ESPP. As of December 31, 2022, 13,494,698 shares of common stock were available for future issuance under the ESPP.

As of December 31, 2022, there was approximately $3.1 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 $1.9 million and $1.2 million of share-based compensation expense related to the ESPP for the three months ended December 31, 2022 and 2021, respectively, and $5.4 million and $3.6 million of share-based compensation expense related to the ESPP for the nine months ended December 31, 2022 and 2021, respectively.
