projected gain financial

"Projected gain: NT$37,904 thousand for disposal"

related party financial

"Whether the counterparty of the current transaction is a related party"

A related party is a person or organization with close ties to a company — for example major shareholders, board members, executives, their family, or businesses they control — that can influence decisions or enter into transactions with the company. Investors watch related‑party dealings because they can create conflicts of interest or non‑market terms that affect fairness, the company’s finances and transparency; think of it like buying or selling something to a family member rather than on the open market.

material information regulatory

"it is a material information for the Company to acquire and disposal equipment"

Material information is any fact or development that a reasonable investor would likely consider important when deciding whether to buy, sell or hold a stock—like a new product that could change a company’s prospects or a hidden debt that could hurt its finances. It matters because timely, accurate disclosure of such facts helps ensure fair prices and prevents surprises that can sharply move a stock; think of it as information that can tip the scale in an investment decision.
