Share-based payment award, description |  |  |  | The Company’s 2021 Employee Stock Purchase Plan (the ESPP) allows employees, including executive officers, to contribute up to 15% of their earnings, subject to certain limitations, for the purchase of the Company’s common stock at a price per share equal to the lower of (a) 85% of the fair market value of a share of common stock on the first day of the offering period, or (b) 85% of the fair market value of a share of common stock on the last day of the offering period. The number of shares of common stock reserved for issuance under the ESPP automatically increases on January 1 of each calendar year through and including January 1, 2031, by the lesser of (1) 1% of the total number of shares of the Company’s common stock outstanding on December 31 of the preceding calendar year or (2) a number of shares determined by the Company’s board of directors. Shares subject to purchase rights granted under the ESPP that terminate without having been exercised in full will not reduce the number of shares available for issuance under the ESPP. The number of authorized shares reserved for issuance under the ESPP was increased by 672,554 shares effective as of January 1, 2025 in accordance with the provisions of the ESPP described above.
