Stock-based Compensation

Stock-based Compensation

Our equity incentive plan was established in 2020, for purposes of granting stock-based compensation awards to certain members of our senior management, our non-executive directors and to certain employees, to incentivize their performance and align their interests with ours. We have granted restricted stock units (“RSUs”) to certain employees and non-employee directors that have a service-based vesting condition. In addition, we have granted performance stock units (“PSUs”) to certain members of management that have a performance-based vesting condition. We account for forfeitures of outstanding but unvested grants in the period they occur. A maximum of 10.5 million shares of common stock were initially available for issuance under equity incentive awards granted pursuant to the plan. In the three and six months ended June 30, 2024, zero and 0.3 million RSUs and zero and 0.3 million PSUs were granted, respectively.

As of June 30, 2024, there were stock-based compensation awards representing 1.4 million shares outstanding compared to 0.8 million shares outstanding as of December 31, 2023. Stock-based compensation expense was $5 million and $9 million for the three and six months ended June 30, 2024, respectively, compared to $3 million and $6 million in the comparable prior year periods.
