beneficial owner regulatory

"each of the Reporting Persons may be deemed to be the beneficial owner of the common stock"

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.

shared voting power regulatory

"Shared Voting Power 6,732,770.00"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

shared dispositive power regulatory

"Shared Dispositive Power 6,732,770.00"

Agreement of Joint Filing regulatory

"pursuant to an Agreement of Joint Filing incorporated by reference herein"

exit filing regulatory

"As of June 30, 2026, the Reporting Persons no longer beneficially own more than five percent... This filing represents an exit filing"
