Restricted stock units are awards that give the holder the right to receive one share of common stock for each restricted stock unit upon meeting service-based vesting conditions (typically annual vesting in three equal annual installments, with a requirement that the holder remains in the continuous employment of the Company). The Company determines the fair value of restricted stock-based awards that vest over time based on the market price of the common stock on the date of grant. The holders of unvested units do not have the same rights as stockholders and do not have the right to receive any dividends or the right to vote.

The total fair value of shares vested during the six months ended June 30, 2024 and 2023 was approximately $37.1 million and $20.5 million, respectively. Unrecognized compensation expense related to outstanding restricted stock units to employees and directors as of June 30, 2024 and 2023 was $28.2 million and $24.0 million, respectively, and is expected to be expensed over the next 2.3 years.

Performance share units ("PSUs") are awards that give the holder the right to receive one share of common stock for each PSU upon meeting performance or market-based vesting conditions. These conditions typically include the attainment of specific metrics over a defined period. The fair value of the PSUs is determined based on either the grant date fair value for performance metrics or using a Monte Carlo simulation for market based awards. The Company recognizes expense if the metrics are probable of being achieved and expensed using either a straight line or an accelerated attribution model. Additionally, the Company recognizes compensation expense for non-employees in the same manner and periods as though cash had been paid for services received.

In the third quarter of 2022, the Human Resources and Compensation Committee of the Board of Directors approved the issuance of PSUs to certain employees. The aggregate grant date fair value of $7.5 million included an immediate vesting of 20% of the shares as well as specific performance-based metrics to be met in year one and year two of the issuance. The Company believes the performance-based metrics are probable of being achieved and will recognize expense for each tranche of the awards separately using the accelerated attribution method according to ASC 718.

In March 2024, the Human Resource and Compensation Committee approved PSUs under the 2015 Plan with an aggregate award of approximately 65,000 shares of the Company's common stock for certain officers of the Company. Each PSU is initially equivalent in value to one share of Celsius' common stock. The PSUs vest over a period of three years from the grant date based on continuous service, with the number of shares earned (50% to 200% of the target awarded) depending upon the extent to which the Company can achieve certain financial and market performance targets measured over the period beginning January 1, 2024 through December 31, 2026. Approximately one-third of the PSUs were valued at $79.27 per PSU based on the Company's common stock price on the grant date, and the financial targets for vesting are based on the Company's achievement of certain revenue metrics. The Company recognizes the grant-date fair value of these PSUs, as stock-based compensation expense ratably over the vesting period based on the number of awards expected to vest at each reporting date. The remaining PSUs were valued

using a Monte Carlo simulation model. This model incorporates assumptions such as the risk-free interest rate based on zero-coupon yields implied by U.S. Treasury issuances, expected volatility derived from historical data of the Company and certain indices. The Company recognizes the grant-date fair value of these awards as stock-based compensation expense ratably over the vesting period. Approximately one-third of the performance target for vesting is based on total shareholder return ("TSR") relative to the Company's peer group, with each PSU valued at $134.75. The remaining one-third have a vesting performance target based on a specific market price, with each PSU valued at $20.25.
