Rule 10b5-1 trading plan regulatory

"Sale made pursuant to the Reporting Person's approved 10b5-1 trading plan adopted on October 9, 2025."

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.

weighted average sale price financial

"The price reported above reflects the weighted average sale price."

beneficial owner financial

"therefore may be deemed to be the beneficial owner of such shares."

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.
