 value and make decisions focused on the long-term success of our company, while RSUs strengthen the retention of the executive team. Our PSU awards promote achievement of long-term strategic goals that underlie those awards as performance metrics.

In January 2024, our Compensation Committee granted the following awards, as set forth in more detail in the chart below:

• stock options, which vest 25% on the first anniversary of the date of grant, with the remainder vesting in 36 monthly installments thereafter, subject to continued service through each vesting date;

• RSU awards, one-third of which vest on each of the first three anniversaries of the date of grant, subject to continued service through each vesting date; and

• PSU awards, which vest as described below.

The PSU awards (the “ 2024 Executive PSUs ”) are subject to a performance condition of achieving certain net product sales levels during the year ending December 31, 2025. If the performance condition is met, the first tranche of the award will vest on March 15, 2026 and the second tranche will vest on March 15, 2027, subject to continued service through each vesting date. The number of units to be vested in the first tranche of the PSU award is calculated by multiplying two-thirds of the shares subject to the PSU award by a percentage calculated based on attained net sales metrics, as certified by the Compensation Committee. The number of units to be vested in the second tranche of the PSU awards equals 50% of the units vested in the first tranche.
