Footnotes from the filing
Each Restricted Share Unit (RSU) and Performance Share Unit (PSU) converts into common stock on a one-for-one basis.
The number of PSUs earned and issued upon vesting was determined based on goals (set by the Compensation Committee of the Issuer's Board of Directors (the "Compensation Committee") on an annual basis) for each of the three fiscal years ended December 31, 2025. Based on the Compensation Committee's determination of achievement of these pre-established financial goals, 32%, 70% and 36% of the shares subject to the 2023, 2024 and 2025 financial periods, respectively, were earned and vested on April 17, 2026.
Every dated public record OQRO holds about the company from 60 days before to 120 days after, oldest first. It shows what was going on; none of it is a stated reason for the trade.
