The 2026 Plan provides that the aggregate number of shares authorized for issuance under the 2026 Plan will automatically increase on January 1 of each year for a period of ten years commencing on January 1, 2027 and ending on (and including) January 1, 2037, in an amount equal to 5% of the total number of shares of common stock, plus the total number of shares of common stock issuable upon settlement of pre-funded warrants (if any), in each case, outstanding on December 31 of the preceding year; provided, however, that the Registrant's board of directors may act prior to January 1st of a given year to provide that the increase for such year will be a lesser number of shares. Pursuant to Rule 416(a) promulgated under the Securities Act of 1933, as amended (the "Securities Act"), this registration statement shall also cover any additional shares of common stock that become issuable by reason of any stock dividend, stock split, recapitalization or other similar transaction with respect to the shares of common stock being registered pursuant to this registration statement.
