Added
The success of our business and results of operations is dependent on our executive officers and other key personnel.
Added
Beginning in 2021, in order to improve our ability to retain and recruit such persons, as well as to better align our executive compensation program with the interests of our stockholders, we implemented a long-term incentive program under our 2021 Equity Incentive Plan (the “2021 Plan”) pursuant to which we grant performance-based equity awards that vest on the achievement of specified performance goals for a specified three-year period.
Added

Added
On June 12, 2024, the Compensation Committee certified that we exceeded the maximum performance target level for each of the performance targets set for the performance awards granted in June 2021 (the “2021 PSUs”). Therefore, executives holding such awards were entitled to payment of the 2021 PSUs at 200% of the target number of shares.
Added
On June 6, 2024, at the annual meeting of stockholders, a proposal to increase the number of shares of common stock authorized for issuance under the 2021 Plan by 2,000,000 shares was not approved, and as a result, the Company did not have sufficient shares of common stock available for issuance under the 2021 Plan to issue all of the shares payable pursuant to the 2021 PSUs.
Added
As a result, the Company settled the excess portion of the 2021 PSUs in cash, instead of in shares, resulting in reduced cash on the balance sheet and recognition of an additional $2.8 million of stock-based compensation expense for the three months ended June 30, 2024.
Added
If the Company is not able to obtain shareholder approval for additional shares of common stock under the 2021 Plan in the future that are sufficient to permit outstanding awards to be settled in shares, the Company may have to incur additional cash expenditures to settle such awards in cash in lieu of shares.
