foreign private issuer regulatory

"FORM 6-K REPORT OF FOREIGN PRIVATE ISSUER PURSUANT TO RULE 13a-16"

A foreign private issuer is a company organized outside the United States that meets tests showing it is primarily foreign-controlled and therefore qualifies for a different set of U.S. reporting rules. For investors, that means the company files less frequent or differently formatted disclosures with U.S. regulators and may follow home-country accounting and governance practices, so buying its stock is like dining at a well-reviewed restaurant that follows its home kitchen’s rules instead of the local menu — you get access but should check what standards apply.

Chief Financial Officer financial

"appointed Mr. Louis Ho Ming Leung as chief financial officer of the Company"

A Chief Financial Officer (CFO) is the person in charge of a company's money and financial planning. They decide how to spend, save, and invest funds to help the company grow and stay stable. Their role is important because good financial decisions keep the company healthy and successful.

independent non-executive director financial

"Mr. Leung is currently an independent non-executive director of GR Life Style"

An independent non-executive director is a board member who is not part of a company’s day-to-day management and has no close ties to major owners, so they can offer unbiased oversight of strategy, risks, and executive pay. For investors, they act like an impartial referee who helps prevent conflicts of interest, improve transparency and hold management accountable, which can reduce governance risk and protect shareholder value.

forward-looking statements regulatory

"Certain statements in this announcement are forward-looking statements."

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
