Restricted Stock Units financial
"Reflects release of restricted stock units that were previously reported on a Form 4."
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
Uniform Gift to Minor Act financial
"The Reporting Person is custodian under the Uniform Gift to Minor Act of 16,630 shares held..."
dispositive power financial
"The Reporting Person has sole voting and dispositive power with respect to shares held by Birchview Fund, LLC..."
Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
pecuniary interest financial
