Stock Plans

2023 Equity Inducement Plan

On October 11, 2023, our Board of Directors approved and adopted our 2023 Equity Inducement Plan (the “2023 EINP”). On the effective date of the 2023 EINP, 2,000,000 shares of our common stock were reserved for issuance and as of December 31, 2023, there were 1,756,098 shares of common stock available for future issuance. The 2023 EINP permits the granting of non-qualified stock options and restricted stock unit awards. The 2023 EINP terminates on the later of (i) October 11, 2033 or (ii) ten years from the last date that additional shares are added to the EINP by the Compensation Committee of our Board of Directors.

2023 Equity Incentive Plan

On April 7, 2023, our Board of Directors adopted our 2023 Equity Incentive Plan (the “2023 EIP”), which was subsequently approved by our stockholders and became effective on June 7, 2023, replacing our 2013 Equity Incentive Plan (the “2013 Plan”). On the effective date of the 2023 EIP, 12,000,000 shares of our common stock were reserved for issuance. On June 6, 2023, the date on which the 2013 Plan expired, all remaining shares available for grant under the 2013 Plan were cancelled, and we will not make any additional grants under the 2013 Plan. In addition, any shares subject to awards, including shares subject to awards granted under the 2013 Plan that were outstanding on June 7, 2023, that are cancelled, forfeited, repurchased, expire by their terms without shares being issued, are used to pay the exercise price of an option or stock appreciation right or withheld to satisfy the tax withholding obligations related to any award, will be returned to the pool of shares available for grant and issuance under the 2023 EIP. As of December 31, 2023, there were 11,877,920 shares available for grant under the 2023 EIP. The 2023 EIP permits the granting of incentive stock options, non-qualified stock options, RSUs, restricted stock awards, stock bonus awards, stock appreciation rights and performance awards. The 2023 EIP terminates on April 7, 2033.

Amended and Restated 2013 Employee Stock Purchase Plan

On April 7, 2023, our Board of Directors adopted our Amended and Restated 2013 Employee Stock Purchase Plan (the “A&R ESPP”), which was subsequently approved by our stockholders and became effective on June 7, 2023. The A&R ESPP permits eligible employees to purchase shares of our common stock by accumulating funds through periodic payroll deductions. The A&R ESPP is intended to qualify as an "employee stock purchase plan" under Section 423 of the Code. Under the A&R ESPP, eligible employees will be granted an option to purchase shares of our common stock at a 15% discount to the lesser of the fair market value of our common stock on (i) the first trading day of the applicable offering period or (ii) the last day of each purchase period in the applicable offering period. The Compensation Committee of our Board of Directors shall determine the duration and commencement date of each offering period, provided that an offering period shall in no event be longer than twenty-seven (27) months, except as otherwise provided by an applicable sub-plan. Upon approval of the A&R ESPP, the available share pool under our existing 2013 Employee Stock Purchase Plan was reduced, and we have reserved 4,000,000 shares of our common stock under the A&R ESPP. As of December 31, 2023, there were 3,866,559 shares of common stock available for future issuance under the A&R ESPP.
