Frequently asked questions
What is United Microelectronics's revenue?
United Microelectronics's trailing twelve-month revenue is $240.73B, and consensus projects about $537.75B by 2030. Revenue is the top line the whole model builds on, and at this scale the question shifts from how fast it grows to whether margins hold as it compounds.
How profitable is UMC?
In its most recent fiscal year, UMC ran a gross margin of 29.01%, an operating margin of 18.50%, and a net margin of 17.56%. Margins this high mean most of each extra dollar of revenue drops through to profit, which is the signature of real pricing power.
How much free cash flow does UMC generate?
UMC produced $52.40B in free cash flow in its most recent fiscal year. Free cash flow is what is left after running and reinvesting in the business, and it is the cash that actually funds buybacks, dividends, and a stronger balance sheet.
Is UMC's balance sheet healthy?
UMC holds $110.66B in cash and equivalents against $45.37B in long-term debt, on $379.77B of shareholder equity. Cash on hand exceeds long-term debt, so the balance sheet adds little financial risk to the thesis.
