"Each Restricted Stock Unit ("RSU") represents a contingent right to receive one share of the Issuer's Common Stock."
Rule 10b5-1 trading plan regulatory
"The sale reported in this Form 4 was effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person..."
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
beneficial owner regulatory
"By virtue of these relationships, the Reporting Person may be deemed to be the beneficial owner of the securities held of record by BioXcel LLC."
A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.
pecuniary interest financial
"The Reporting Person disclaims beneficial ownership of the securities reported herein except to the extent of his pecuniary interest therein."
Vesting Commencement Date financial
"...on the six-month anniversary of the original promise date of November 4, 2025 (the "Vesting Commencement Date")..."
The vesting commencement date is the starting point when an employee begins earning ownership rights to their promised benefits, such as stock options or retirement contributions. Think of it like the day a savings account is opened—only after this date do the benefits start to grow and become fully available over time. It matters to investors because it marks when the clock begins ticking toward full ownership, affecting the timing and value of these benefits.
