As of September 2022, an aggregate of 3,500,000 shares of common stock were authorized for issuance under the Plan. In March 2023, the stockholders approved an amendment to the Plan, as amended to date, to (i) increase the number of shares authorized for issuance thereunder from 3,500,000 shares of common stock to 11,512,000 shares and (ii) add an evergreen provision to, on April 1st and October 1st of each year, automatically increase the maximum number of shares of common stock available under the Plan to fifteen percent (15% ) of the Company's outstanding shares of common stock, in each case as of the last day of the immediately preceding month. On March 31, 2023, there were 96,950,555 outstanding shares of common stock, and accordingly on April 1, 2023, the total shares authorized for issuance under the Plan increased to 14,542,583. As of June 30, 2023, after giving effect to the evergreen provision and the effectiveness of grants of equity awards that were conditioned on stockholder approval of the amendment to the Plan, there were 4,839,019 shares available and authorized for issuance under the Plan.
