Mirum Pharmaceuticals, Inc. (Nasdaq: MIRM) today announced that on February 10, 2026, the Compensation Committee of Mirum’s Board of Directors granted inducement awards consisting of non-qualified stock options to purchase 163,040 shares of common stock, 219,090 restricted stock units (“RSUs”), and 48,880 performance stock units (“PSUs”) to 37 new employees under Mirum’s 2020 Inducement Plan. The Compensation Committee of Mirum’s Board of Directors approved the awards as an inducement material to the new employees’ employment in accordance with Nasdaq Listing Rule 5635(c)(4).

Each stock option has an exercise price per share equal to $100.91 per share, Mirum’s closing trading price on February 10, 2026, and will vest over four years, with 25% of the underlying shares vesting on the one-year anniversary of the applicable vesting commencement date and the balance of the underlying shares vesting monthly thereafter over 36 months, subject to the new employees’ continued service relationship with Mirum through the applicable vesting dates. The RSUs will vest over three years, with 33% of the underlying shares vesting on each anniversary of the applicable initial vesting date, subject to the new employees’ continued service relationship with Mirum through the applicable vesting dates. The PSUs are subject to two performance conditions of achieving certain net product sales levels during the years ending December 31, 2027 and 2028 and, if the performance conditions are met, the applicable tranche of the awards will vest on March 15, 2028 and March 15, 2029, subject to continued service with Mirum through the applicable vesting dates. The number of PSUs to be vested in the first tranche of the PSU awards is calculated by multiplying 50% of the shares subject to the PSU award by a percentage calculated based on attained net sales metrics in the year ended December 31, 2027, as certified by Mirum’s Board of Directors or its Compensation Committee. The number of PSUs to be vested in the second tranche of the PSU awards is calculated by multiplying 50% of the shares subject to the PSU award by a percentage calculated based on attained net sales metrics in the year ended December 31, 2028, as certified by Mirum’s Board of Directors or its Compensation Committee. The awards are subject to the terms and conditions of Mirum’s 2020 Inducement Plan and the terms and conditions of an applicable award agreement covering the grant.
