treasury shares financial

"approved the cancellation of the Company’s treasury shares"

Treasury shares are a company’s own stock that it has repurchased and keeps on its books instead of canceling or leaving in the hands of outside investors. Think of them like coupons a business puts back in a drawer: they don’t vote or receive dividends while held, but they can be reissued later for employee pay or fundraising. For investors this matters because buybacks change the number of shares that count toward earnings and ownership, can boost per‑share metrics, and use corporate cash that might otherwise go to growth or dividends.

open-market purchase financial

"Method of Acquisition of Treasury Shares for Cancellation | | Open-market purchase"

An open-market purchase is when an investor or a company buys shares on a public stock exchange at the going market price, rather than through a private deal. It matters to investors because these purchases change how many shares are available, can push the stock price up or signal confidence from large buyers, and often affect per-share metrics like earnings—think of it like someone buying lots of apples off a grocery shelf, reducing supply and potentially raising the price.

par value financial

"Par Value Per Share (Won) | | 5,000"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.

independent directors regulatory

"Attendance of Independent Directors | | Present: 6; Absent: 0"

Members of a company’s board who do not have significant business, family, or financial ties to the company and are not part of its management; they are chosen to provide impartial oversight of strategy, financial reporting, executive pay and risk. They matter to investors because independent directors act like an objective referee, helping ensure decisions favor shareholders’ long-term interests rather than insiders, which can strengthen trust and reduce the chance of mismanagement or conflicts of interest.
