Filing Explained

At June 30, cash was NT$91,292 million against NT$306,230 million of debt; third-quarter segment targets remain management projections.

Key Terms

purchase price allocation, EBITDA, net debt to equity ratio, advanced packaging, +2 more

6 terms

purchase price allocation financial

"PPA expenses are the P&L impacts from the accounting treatment of purchase price allocation"

Purchase price allocation is the accounting process that breaks down the total amount paid for an acquired business into specific pieces—like tangible assets, identifiable intangible assets (brands, patents, customer lists) and goodwill—based on their estimated fair values. Investors care because this breakdown affects future earnings, tax costs and reported asset values: higher allocations to amortizable intangibles or goodwill can change profit volatility, depreciation and potential impairment charges, similar to splitting a restaurant bill to see what you actually bought versus what you paid extra for goodwill.

EBITDA financial

"EBITDA stands for net income or loss before interest, taxes, depreciation, amortization"

EBITDA stands for earnings before interest, taxes, depreciation, and amortization. It measures a company's profitability by focusing on the money it makes from its core operations, ignoring expenses like taxes and accounting adjustments. Investors use EBITDA to compare how well different companies are performing financially, as it provides a clearer picture of operational success without the influence of financial structure or accounting choices.

net debt to equity ratio financial

"Net debt to equity ratio 0.47 0.40"

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.

advanced packaging technical

"Leading-edge advanced packaging and overall testing outpaced growth"

Advanced packaging describes modern methods for arranging, connecting and enclosing semiconductor chips so they work together more efficiently in a smaller space—think of stacking and wiring tiny electronic building blocks instead of leaving them as separate items on a circuit board. It matters to investors because these techniques can boost product speed, reduce power use, shrink device size and lower manufacturing costs, all of which influence a maker’s competitiveness, profit margins and market share.

LEAP services financial

"LEAP services revenue is tracking ahead of prior guidance of US$3.5 billion"

right-of-use assets financial

"intangibles, right-of-use assets, other assets, and deferred tax liability"

Right-of-use assets are the rights a company gains to use a physical space or equipment under a lease agreement. They are recorded as assets on the company's balance sheet, reflecting the value of future benefits from the leased item. For investors, these assets provide a clearer picture of a company's obligations and resources related to leasing arrangements, helping to assess its financial health and operational commitments.
