Note 17 – Employee benefit plan

401(k) retirement savings plan

The Company maintains a defined contribution 401(k) retirement savings plan for the benefit of its employees, including its named executive officers, who satisfy certain eligibility requirements. Under the 401(k) plan, eligible employees may elect to defer a portion of their compensation, within the limits prescribed by the Code, on a pre-tax or after-tax (Roth) basis, through contributions to the 401(k) plan. The 401(k) plan is intended to qualify under Sections 401(a) and 501(a) of the Code. As a tax-qualified retirement plan, pre-tax contributions to the 401(k) plan and earnings on those pre-tax contributions are not taxable to the employees until distributed from the 401(k) plan, and earnings on Roth contributions are not taxable when distributed from the 401(k) plan. In July 2021, the Company began making matching contributions of up to 2% of eligible compensation, as contributed by eligible participating employees. Employer matching contributions vest 25% per year over four years. The Company contributed $228,000, net of forfeitures, to the 401(k) plan for the year ended December 31, 2021.
