Stock-Based Compensation Equity Plans The Company grants stock-based awards under its 2021 Stock Option and Incentive Plan (the “2021 Plan”), which was approved by its stockholders in February 2021 and amended and restated in January 2023. The Company also has outstanding stock option awards under its 2017 Stock Option and Grant Plan (the “Private Disc Plan”) but is no longer granting awards under this plan or its 2021 Inducement Plan. The Company also grants awards under its 2021 Employee Stock Purchase Plan (the “2021 ESPP”), which was approved by the Company's stockholders in July 2021 and amended and restated in January 2023.
