Restricted Stock Units financial

"Vesting of restricted stock units ("RSUs") granted to the Reporting Person"

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.

pecuniary interest financial

"disclaims beneficial ownership of the shares held by the Trust except to the extent of his pecuniary interest therein"

dispositive power financial

"may be deemed to have voting and dispositive power with regard to the shares held by the Trust"

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.

family limited partnership financial

"GV Partners L.P. is a family limited partnership of which the Reporting Person is the managing member"

contingent right financial

"Each RSU represents a contingent right to receive one share of the Issuer's common stock upon settlement"
