ex-dividend record date financial

"The Board resolved that the ex-dividend record date for common shares will be July 5, 2026."

book closure period financial

"the book closure period will be from July 1 to July 5, 2026."

capital surplus financial

"NT$1.23 per common share will be distributed to the Company’s shareholders in cash from its capital surplus."

Capital surplus is the portion of a company’s equity that comes from money investors paid above the stock’s stated minimum price or from certain non-operating transactions; it sits on the balance sheet separate from earned profits. Investors watch it because it shows how much extra funding a company has raised beyond basic share value—like tips above a ticket price—and can provide a financial cushion for growth or restructuring, though it is not the same as cash available for routine dividends.

Annual Shareholders’ Meeting regulatory

"the Annual Shareholders’ Meeting resolved that NT$1.23 per common share will be distributed"

A company's annual shareholders’ meeting is a yearly gathering where owners of the company review performance, vote on key decisions (like electing the board or approving executive pay), and ask management questions. Investors care because it’s the main forum to influence how the company is run and to get direct updates—think of it as a town hall where owners judge leaders and set the rules that affect the value of their investment.
