Converted Awards

On November 13, 2023, the Company entered into the employee matters agreement with the Former Parent under which the Company agreed to convert all outstanding Former Parent stock options and RSUs held by the Company’s employees under the Former Parent’s share-based compensation plans into the Company stock options and RSUs under the 2023 Plan in accordance with the conversion ratio set forth in the agreement. On December 14, 2023, the Former Parent and the Company amended the employee matters agreement to adjust the conversion ratio used to calculate the number of the Company’s RSUs issuable to each employee in exchange for each RSU of Alkermes. All outstanding equity awards held by the Company’s employees were converted and issued under the 2023 Plan in December 2023 in accordance with the amended employee matters agreement. Except for the number of underlying shares and the exercise price of the stock options, the converted awards retain substantially the same terms and conditions of the original awards, including their term and vesting conditions.

Stock Plan Activity

The weighted average grant date fair value of stock options granted during the six months ended June 30, 2025 and 2024 was $2.60 and $3.76 respectively.

At June 30, 2025, there were 1.9 million stock options vested or expected to vest, with a weighted average exercise price of $4.55 per share, a weighted average contractual remaining life of 2.7 years and no aggregate intrinsic value. At June 30, 2025, there was also no aggregate intrinsic value of stock options exercisable with a weighted average remaining contractual term of 2.1 years. The number of stock options expected to vest was determined by applying the pre-vesting forfeiture rate to the total number of outstanding options. The intrinsic value of a stock option is the amount by which the market value of the underlying shares exceeds the exercise price of the stock option.

At June 30, 2025, there was $0.2 million of unrecognized share-based compensation expense related to unvested stock options, which is expected to be recognized over a weighted average period of 1.5 years.

The weighted average grant date fair value of RSUs granted during the three months ended June 30, 2025 and 2024 was $1.24 and $4.24, respectively. At June 30, 2025, there was $0.1 million of unrecognized share-based compensation expense related to unvested RSUs, which will be recognized over a weighted average remaining contractual term of 1.6 years.

The Company recorded a credit to share-based compensation expense, net of current period expense, of $1.1 million, as a result of current period pre-vesting forfeitures and expected pre-vesting forfeitures in future periods following a reduction-in-force.
