Biggest thing to watch: the price is not yet in a clear uptrend, so timing is the risk more than the business. ## What is the United Microelectronics share price today? United Microelectronics Corporation's share price was $16.40 at the close on 3 November 2026. It has been moving sideways for 2 weeks. That is 4.3% below its average price over the last 200 trading days. In the last 52 weeks it traded between $7 and $26, and at that close it sat 48% of the way up from that low. Over the past 13 weeks it has done worse than the S&P 500, and it has been behind for 5 weeks running. Over the last 10 years the share price moved +716% while the S&P 500 moved +255%, so it is ahead of the index over that whole period. It was last ahead over 13 weeks in the week of 2 October 2026. The chart above shows the 13-week comparison for every week. This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row. ## What dividend does United Microelectronics pay? United Microelectronics Corporation declared TWD 2.60 per local share for Dec 2025. It reports in Taiwan dollars, and one US-listed share can stand for several local shares, so we do not set this against the dollar price or show a yield. ## Which stock lists is United Microelectronics on? United Microelectronics is on one of our US lists: US tech stocks. [US tech stocks](https://www.sectoralpha.in/us-tech-stocks)

## Is United Microelectronics profitable? United Microelectronics Corporation earned TWD 42.3 B of net profit in the Jun 2026 quarter, +374.7% on the same quarter a year earlier. That is the 4th quarter in a row of profit growth. Full-year FY25 profit was TWD 41.7 B. Over 4 years profit has grown −5.0% a year on average. That is 61.5% of the quarter's revenue. The same quarter a year earlier earned TWD 8.9 B. For the full year, FY25 profit was TWD 41.7 B (−11.6% on the year before). Why profit moved: revenue changed +17.0% on a year earlier and the margin moved +3.3 percentage points. Most of the change came from keeping more of each sale. On average over the last four quarters, profit changed +126.1% and revenue +5.7%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra dollar of revenue adds more to profit. This company reports in Taiwan dollars, not US dollars, so the money charts are left out here. The figures in the text are in that currency (TWD); nothing is converted. ## How much revenue does United Microelectronics make, and is it growing? United Microelectronics Corporation reported TWD 68.7 B of revenue in the Jun 2026 quarter, +17.0% on the same quarter a year earlier. That is the 3rd quarter in a row with growth on the year before. Over 4 years it has grown 2.8% a year on average. The last full year, FY25, came in at TWD 238 B. The last four reported quarters add to TWD 251 B. FY25 revenue was TWD 238 B, +2.3% on the year before. Recent pace: the last four quarters grew +5.7% on average, against 2.8% a year over the longer run, so this year is growing faster than its own long-run rate. Is growth speeding up? Revenue over the last 12 months grew +5.6%, against +5.9% a year over the last 8 quarters (stabilising); profit over the last 12 months grew +110.5%, against +25.0% a year (accelerating). This company reports in Taiwan dollars, not US dollars, so the money charts are left out here. The figures in the text are in that currency (TWD); nothing is converted. ## How much of its sales does United Microelectronics keep? United Microelectronics Corporation's operating margin was 21.7% in the Jun 2026 quarter, 3.3 percentage points higher than the same quarter a year ago. Across 5 years it has been between 18.5% and 37.2%. The latest quarter is within that range. Why the margin moved: operating margin changed +3.3 percentage points on the year while gross margin changed +3.8 points. So the gain came mostly from the gross margin, which means input costs and prices charged. ## Is United Microelectronics' profit turning into cash? Over the last 3 years, 187% of United Microelectronics Corporation's reported profit came in as cash from its operations, so the profit is backed by cash. In FY25 it brought in TWD 99.9 B of operating cash against TWD 41.7 B of profit. After TWD 47.7 B of spending on assets, TWD 52.1 B was left over as free cash. Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year. Why: the cash figure is clear, but the day counts behind it are not in our data, so we show it without guessing the reason. What to look at next: the main use of cash is spending on assets. The next section checks what that spending is building. This company reports in Taiwan dollars, not US dollars, so the money charts are left out here. The figures in the text are in that currency (TWD); nothing is converted. ## Where does United Microelectronics' cash go? United Microelectronics Corporation does not report the customer, stock and supplier day counts a cash cycle needs, so this section looks at its spending on assets instead. It spent TWD 228 B on assets over the last 3 years. Averaged over those years that is 32.0% of FY25 revenue a year. Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn. Spending on assets: TWD 228 B over the last 3 years. In short: the cash is going into new capacity, not getting stuck in the daily cycle. The question is whether the new capacity earns. This company reports in Taiwan dollars, not US dollars, so the money charts are left out here. The figures in the text are in that currency (TWD); nothing is converted. ## What is United Microelectronics' P/E ratio, and how does it compare with its own history? United Microelectronics Corporation's P/E is 16.0×, with too little history to compare. This compares the share price with the company’s own past. It does not say what the business is worth. In short: there is too little history to say whether the multiple is high or low for this company, so the earnings trend underneath matters more than the multiple. ## Is the United Microelectronics business getting better or worse? United Microelectronics Corporation's business trend cannot be read yet. There are fewer than eight usable quarters of growth figures, so there is not enough history to read the trend. This is based on 12 quarters of 3 measures, with some gaps. Why it matters: with too little history, we say so rather than guess a direction. The latest quarter’s profit includes a one-off item bigger than the normal business, so the profit line is shown but does not count in this reading. There are fewer than eight usable quarters, so this page does not guess a direction from so little history. ## How much does United Microelectronics earn on its capital? United Microelectronics Corporation earned a ROE of 11% in FY25. Its return on capital used (ROIC) is 0.2 percentage points above its cost of capital, so growth here adds value, not just size. It comes from a 17.6% net margin and 0.41× asset turnover (sales divided by assets). Why the return is what it is (FY25): a 17.6% net margin × 0.41× asset turnover × 1.52× leverage (assets divided by equity) ≈ 11.0% on equity. The margin does most of the work; borrowing plays a small part, so this return is earned, not borrowed. The key test, return on capital used minus the cost of capital: 13.1% − 12.9% = +0.2 percentage points. The 12.9% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. Positive but thin: it creates value with little room for error. The 13.1% ROIC above is the latest reading, as reported. The yearly chart below shows FY25 at 10.9%, and the quarterly chart works out each 12-month window from the quarterly figures, so the readings differ by date, not by method. ## Does United Microelectronics have too much debt? United Microelectronics Corporation has total debt of TWD 63.4 B against shareholder equity of TWD 444 B as of Jun 2026, so its debt is 0.14× its equity, which is very little. Year by year, that ratio went from 0.32 in FY21 to 0.21 in FY25. So the returns on this page come from the business, not from borrowed money. This company reports in Taiwan dollars, not US dollars, so the money charts are left out here. The figures in the text are in that currency (TWD); nothing is converted. ## What is the United Microelectronics shareholding pattern? We have no ownership or short-position figures for United Microelectronics Corporation, so this section says so rather than fill the gap. At normal trading volumes, closing those positions would take about 2.6 days. US companies do not publish a quarter-by-quarter list of owners, so this page uses short interest instead. ## How far is United Microelectronics from balance-sheet trouble? For United Microelectronics Corporation, the Z-score is 4.82. A Z-score above about 3 is safe and below about 1.8 signals danger, so this is well clear of danger. It estimates how far the balance sheet is from trouble; it is not a forecast of failure. Why it matters: a Z-score of 4.82 is well clear of the danger zone, so the balance sheet is not the risk here. ## How does United Microelectronics rank in its industry? There is no score against its industry: United Microelectronics Corporation is not among the largest members shown in this industry comparison for Semiconductors. The score ranks a company within its industry: each measure is scored against the other members. Without that group there is no score, so none is shown. ## Which companies is United Microelectronics compared with?

This page does not forecast United Microelectronics Corporation's stock price. What it shows instead: the stock price is $16.40, and it has been moving sideways for 2 weeks. Nobody can reliably say which way a price will move, and this site does not try (as of 3 November 2026). ### Does United Microelectronics have too much debt? No, United Microelectronics Corporation has little debt: its debt is 0.17× its equity. A year-by-year history of its borrowings is not in our data, so this uses the latest reading.
