beneficial owner regulatory

"they have ceased to be beneficial owners of more than 10% of the Issuer's 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.

Section 16 regulatory

"therefore are no longer subject to Section 16 of the Exchange Act"

Section 16 is a U.S. securities law rule that governs the trading and disclosure obligations of company insiders — typically officers, directors and large shareholders — to promote transparency and deter unfair profit-taking. It requires insiders to publicly report their stock trades and allows companies or the issuer to reclaim quick, short-term profits from certain insider trades, like a scoreboard and a refund policy that help investors see and limit possible insider advantage.

"may be deemed to have been indirectly beneficially owned by the other Reporting Persons"

"disclaims beneficial ownership of the securities reported herein, except to the extent of such Reporting Person's pecuniary interest"
