treasury stock financial

"Number of treasury stock | | 10,057,855 shares"

Treasury stock is shares that a company has bought back from the public and kept in its own control rather than retiring them. Think of it like a company holding its own tickets in a drawer: those shares no longer vote or receive dividends while held, but the company can reissue or retire them later; this reduces the number of shares available to outside investors and can boost per‑share earnings and influence ownership and stock price.

discretionary dealing contract financial

"Market purchases based on a discretionary dealing contract regarding repurchase of its own shares"

Companies Act regulatory

"pursuant to Paragraph 1 of Article 459 of the Companies Act, and Cancellation of Repurchased Shares pursuant to Article 178 of the Companies Act"

Companies Act is the primary law that sets the rules for forming, running and winding up corporations, covering directors’ duties, shareholder rights, financial reporting, audits and insolvency. For investors it matters because those rules determine how transparent and accountable a company must be, what protections shareholders have, and how risks are managed—think of the Act as a rulebook and referee that helps ensure fair play and reliable information for investment decisions.
