The number of shares of Common Stock available for issuance under the 2021 Plan is subject to an automatic annual increase on January 1 of each year beginning in 2022 and ending on (and including) January 1, 2031 in an amount equal to the least of: 1) four percent (4%) of the outstanding shares of the Company’s common stock on the last day of the immediately preceding fiscal year; or 2) such number of shares of the Company’s common stock as the administrator of the 2021 Plan may determine (the “Evergreen Provision”).

In addition, at the Company’s annual meeting of stockholders held on June 23, 2026, the stockholders of the Company approved an amendment to the 2021 Plan to increase the number of shares of Common Stock authorized for issuance thereunder to 2,144,622 shares (the “Amendment”).
