Insights

Award ties executive pay to a regulatory milestone and change-in-control within four years.

The 125,000 performance stock unit award vests only upon the earlier of NDA approval for seralutinib or a change in control, and is limited to the fourth anniversary of the grant. This structure links compensation to a specific corporate outcome rather than time-based vesting.

The award was granted at a $0 price and increases the reporting person’s direct beneficial ownership to 710,934 shares while also noting 45,892 and 22,222 shares held indirectly. The instrument is contingent on continued service, which retains retention leverage for the company.
