Investors may watch segment trends, capex levels, and customer concentration in future quarters.

Key Terms

ads, net debt to equity ratio, current ratio

3 terms

ads financial

"Basic earnings per share for the quarter were NT$3.24 (or US$0.205 per ADS)"

Ads are paid promotional messages a company places across media — online, on TV, in print, or on social platforms — to attract customers, explain products, or shape public perception. For investors, ads matter because they drive sales growth, affect how much a company must spend to win customers, and influence brand strength and long-term value. Ads can also create regulatory or reputational risk if claims are misleading, which can affect profits and stock price.

net debt to equity ratio financial

"Current ratio was 1.15 and net debt to equity ratio was 0.40 as of March 31, 2026."

Net debt to equity ratio compares a company’s net debt (total borrowings minus cash on hand) to the owners’ stake in the business (equity), showing how much of the company is financed by borrowing versus owner capital. Investors use it to gauge financial risk and resilience: a higher ratio is like a household with a large mortgage and little savings, which is more vulnerable to interest rises or income drops than one with low debt relative to home value.

current ratio financial

"Current ratio was 1.15 and net debt to equity ratio was 0.40 as of March 31, 2026."

The current ratio measures a company’s short-term ability to pay upcoming bills by comparing assets that can be turned into cash within a year (like cash, inventory, and receivables) to obligations due within the same period. Investors use it like a household budget check — a ratio above 1 suggests the company has more short-term resources than immediate debts, while a very low or very high ratio can signal liquidity risk or inefficient use of assets.
