Stockholders Equity Note [Abstract] |
STOCKHOLDERS' EQUITY | 5. STOCKHOLDERS’ EQUITY At Market Issuance Sales Agreement On September 4, 2020, we entered into an At Market Issuance Sales Agreement, or the 2020 Sales Agreement, with B. Riley Securities, Inc., or B. Riley Securities, pursuant to which we may elect to issue and sell shares of our common stock having an aggregate offering price of up to $100,000,000 in such quantities and on such minimum price terms as we set from time to time through B. Riley Securities as our sales agent. We pay B. Riley Securities an aggregate commission rate equal to up to 3.0% of the gross proceeds of the sales price per share for common stock sold through B. Riley Securities under the 2020 Sales Agreement. For the three months ended March 31, 2021, we sold an aggregate of 7,948,505 shares of our common stock pursuant to the 2020 Sales Agreement, resulting in net cash proceeds to us of approximately $16,234,000, after deducting sales commissions and other offering expenses payable by us. The 2020 Sales Agreement will expire upon the earlier of: (a) the sale of all common stock subject to the 2020 Sales Agreement, or (b) September 4, 2023. 2018 Inducement Award Plan In December 2018, our board of directors approved the adoption of the 2018 Inducement Award Plan, or the Inducement Plan, pursuant to which we reserved 3,000,000 shares of Geron common stock (subject to customary adjustments in the event of a change in capital structure) to be used exclusively for grants of inducement awards to individuals who were not previously Geron employees or directors, other than following a bona fide period of non-employment. In January 2019, February 2020 and February 2021, our Compensation Committee approved amendments to increase the reserve of shares of our common stock under the 2018 Inducement Award Plan by 5,000,000, 1,300,000 and 800,000 shares, respectively. As a result, an aggregate total of 10,100,000 shares of common stock have been reserved under the Inducement Plan. The Inducement Plan provides for the grant of nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock awards, and all awards under the Inducement Plan are intended to meet the standards under Rule 5635(c)(4) of the Nasdaq Listing Rules. The terms and conditions of the Inducement Plan and the inducement awards to be granted thereunder are substantially similar to our stockholder-approved 2018 Equity Incentive Plan.
