The 2021 ESPP became effective immediately prior to the effectiveness of the Company’s registration statement on Form S-1 for its IPO. The 2021 ESPP provides employees the opportunity to purchase shares at a 15% discount at the lower of the share price at the beginning or end of six-month offering periods. 852,971 shares have been reserved and approved for this purpose for the 2021 plan year. Beginning on January 1, 2022, the number of shares reserved and available for issuance under the plan will increase on each January 1 through January 1, 2031, by the lesser of (A) 3,000,000 shares of common stock, (B) 1% of the cumulative number of shares of common stock issued and outstanding on the immediately preceding December 31st or (C) such lesser number of shares of common stock as determined by the Board. On January 1, 2022, an additional 414,513 shares were added to the 2021 ESPP, representing 1% of total common shares outstanding at December 31, 2021.The expense incurred under this plan for the three months ended March 31, 2022 was immaterial to the financial statements. The amounts have been included in the total stock-based compensation line items in the accompanying financial statements and disclosures.

The 2021 Plan became effective immediately prior to the effectiveness of the Company’s registration statement on Form S-1 for its IPO.

To the extent outstanding options granted under the 2018 Plan are cancelled, forfeited, or otherwise terminated without being exercised and would otherwise have been returned to the share reserve under the 2018 Plan, the number of shares underlying such awards will be available for future grant under the 2021 Plan. Beginning on January 1, 2022, the number of shares reserved and available for issuance under the 2021 Plan will increase on each January 1 through January 1, 2031 by the lesser of (A) 5% percent of the number of shares of stock issued and outstanding on the immediately preceding December 31st or (B) such lesser number of shares of common stock as determined by the Board.
