Rules of thumb on reported numbers. A starting point, not a recommendation.
Is it selling more, and how much does it keep?
KIRA summarises the numbers
United Microelectronics Corp had $7.6B of revenue in fiscal 2025, up 5.3% on the year before.
Over five years, revenue changed +4.9% a year on average.
Its operating margin was 18.5%, down 3.7 pts: of every 100 in sales, about 19 is left after running the business.
Revenue
Margins, % of revenue
In plain words: Revenue is all the money customers paid. The margins show how many cents of each dollar of sales are left over at each step: after making the product (gross), after running the business (operating) and after everything, tax included (net).
Loss periods are shown in red.
KIRA summarises the numbers
United Microelectronics Corp made $1.3B of net profit in fiscal 2025.
From fiscal 2016 to 2025, diluted EPS grew 19.7% a year.
Net income
Diluted EPS
In plain words: Net income is the profit left after every cost and tax. Earnings per share (EPS) splits that profit across every share, so it shows what one share earned.
How much cash comes in, and where does it go?
Cash from operations minus capital spending.
KIRA summarises the numbers
Free cash flow was $1.7B in fiscal 2025, 21.9% of revenue.
Free cash flow
Cash from operations vs capital spending
In plain words: Profit on paper is not the same as cash in the bank. Free cash flow is the cash left after paying to run and maintain the business: the money it can hand back to shareholders, save or invest.
Dividends and buybacks
Diluted shares outstanding (annual)
In plain words: Companies hand cash back in two ways: dividends (cash paid to shareholders) and buybacks (buying back their own shares, so each remaining share owns a bigger slice).
Open-market purchases and sales by officers, directors and 10% owners, from Form 4 filings. “Plan” marks trades under a pre-arranged Rule 10b5-1 plan.

In plain words: Insiders are the people who run or own a big part of the company. Buying with their own money can signal confidence; selling often has personal reasons, like taxes or diversifying.
Can it carry its debts, and how well does it use its money?
Cash, debt and the ratios that show how comfortably United Microelectronics Corp can carry it.
KIRA summarises the numbers
United Microelectronics Corp has $2.6B more cash than debt.

| Net debt (− = net cash) | −$3.4B | −$5.4B | −$3.4B | −$2.6B | −$2.6B |
In plain words: What the company owns and what it owes. More cash than debt is a cushion for bad times; a lot of debt leaves less room when business slows down.
After-tax operating income as a share of the money invested in the business: debt plus equity, minus cash.

Its return on capital was 13.1%: every 100 invested in the business earned about 13 in a year.
Return on capital, equity and assets (annual)
