Inducement Awards
On September 2, 2024, the Company entered into an Inducement Equity Award Agreement with a consultant, granting 3,334 restricted stock units ("RSUs") and 1,334 shares of unrestricted common stock (collectively, the “2024 Inducement Awards”) in consideration of services to be rendered to the Company. The 2024 Inducement Awards were granted outside of the 2024 Plan in accordance with Nasdaq Listing Rule 5635(c)(4), but are subject to the terms and conditions of the 2024 Plan. The 3,334 RSUs were granted when the Company’s stock price was $219 per share for a total grant date fair value of $0.7 million and will vest on the first anniversary of the grant date, August 30, 2025, with each vested RSU representing the right to receive one share of the Company’s common stock. The 1,334 shares of unrestricted common stock are not subject to any vesting conditions and were granted when the Company’s stock price was $219 per share for a total grant date fair value of $0.3 million. In September 2024, the 3,334 RSUs were accelerated and fully vested per board approval, resulting in the issuance of 3,334 common stock and the full recognition of the related stock-based compensation expense during the period. For the year ended December 31, 2024, the Company recognized approximately $1.0 million of stock-based compensation in selling, general and administrative expenses related to the 2024 Inducement Awards.
Restricted Stock Units
RSUs are share awards that entitle the holder to receive freely tradeable shares of the Company’s common stock upon vesting. The RSUs cannot be transferred and the awards are subject to forfeiture if the holder’s employment terminates prior to the release of the vesting restrictions. The RSUs generally vest over one or two year cliff period on an annual basis, provided the employee remains continuously employed with the Company. The fair value of the RSUs is equal to the closing price of the Company’s common stock on the grant date.
