How to read UMC
We are not publishing an intrinsic value for this one — the section below says exactly why. Everything on this page that comes straight from the filings and the tape is still here; treat the missing valuation as a known gap, not as a verdict on the business.

Insider and short-interest behaviour needs no valuation model.
The share count we read for UMC looks wrong — common for multi-class / founder-controlled filers that report shares per share-class. That makes per-share figures (including intrinsic value) misleading, so we suppressed them. The company's total financials below are sound.
What to use instead: Lean on the totals — revenue, net income, cash flow — and the balance sheet. Multi-class share counts are being corrected; once fixed, the per-share valuation returns automatically.
This note is only about the single DCF fair-value number — UMC's full financial statements, health scores, and written analysis are all below.
Football field: where does the price sit?
Different valuation methods produce different fair-value ranges depending on assumptions. Plotting them together lets you see at a glance whether the current price is reasonable across approaches, or only one specific lens.
Industry multiples sourced from: industry: Semiconductors. See the Peer Basket section below for the peer comparison and its limited-comparables caveat.
⚠ We found only 2 genuine same-industry (Semiconductors) comparables — fewer than the 4 we require for a reliable median. So we do not derive a peer-implied share value here. Read the multiples as rough context only.
How does UMC stack up against its closest peers?
Ideally we compare UMC only to same-industry peers, but too few exist in our universe right now, so the basket below mixes in broader-sector names. Treat the multiples as rough context, not a valuation. For a leveraged business, EV/EBIT and FCF yield (both in the table) are usually more reliable than EV/Sales, because revenue multiples ignore differences in margins and debt.
▾ What's "EV / Sales" in plain English?
EV (Enterprise Value) = market cap + total debt − cash. It's "what you'd pay to buy the entire company outright" — you pay the market cap to shareholders and take over their debt, but you keep their cash. EV is fairer than market cap alone because it includes the debt the new owner inherits.
EV / Sales = EV ÷ annual revenue. So "2.5×" means investors pay $2.50 of enterprise value per $1 of yearly sales. Higher = market is paying more per dollar of sales (usually because they expect future growth or fat margins).
p25 / median / p75 are the 25th, 50th (middle), and 75th percentile of the peers' multiples. Half the peers fall between p25 and p75. The median (p50) is the typical peer — that's the benchmark we compare to.
Bold middle number = median peer. Half the peers trade above it, half below. Computed over 2 peers (broad — see caveat); implausible multiples excluded.
⚠️ Important caveat: peer multiples only work if the peers are genuinely comparable. Always check the peer list below — if the auto-picker grabbed micro-caps or unrelated businesses, the comparison is noise. A medical-device giant priced against tiny biotech startups won't produce a useful signal.
Bankruptcy + quality screens
Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.
Why it matters: Cheap-looking stocks (low P/E or P/B) often have low Z-scores because the market knows the company is dying. Z-score warns you before you fall into a value trap.
Reference: > 3.0 = safe zone · 1.81–3.0 = grey zone · < 1.81 = distress zone
Full explanation →
Safe zone under the classic Altman thresholds — companies scoring here have historically gone bankrupt only rarely within ~2 years. A screening signal, not a guarantee.
The classic Z-score was calibrated on manufacturers. It is less reliable for asset-light or non-manufacturing businesses (broadcasters, media, software, services) and not applicable to banks, REITs, or insurers — for those the coefficients and the asset-turnover term distort the result. Read it as one screening input, not a verdict.
Why it matters: High score = fundamentals improving. Low score = deteriorating. Especially powerful for filtering cheap stocks: cheap + high F-score historically outperforms; cheap + low F-score is often a value trap.
Reference: 7–9 = strong · 4–6 = mediocre · 0–3 = weak
Full explanation →
The F-score compares two consecutive years of income, cash-flow and balance-sheet data. We have 5 years of income data for this filer, but no machine-readable cash-flow statement or balance sheet — so several of the nine checks have no input at all. We show nothing rather than score a partial year against itself. The reported figures in the financial tables below are unaffected.
What if you assume different inputs?
Here's where we land — and what happens if you change the assumptions. Drag the sliders to set your own Discount RateDiscount Rate — The annual return you demand for taking single-stock risk instead of buying a safe Treasury or index fund.
Why it matters: Higher discount rate = stricter valuation (a stock has to produce more cash to be worth holding). Lower = more generous.
Reference: 8–12% is standard · 9–10% matches S&P 500 historical return · Below 7% is illogical for single-stock risk
Full explanation → (the annual return you demand for single-stock risk) and terminal growth; the value updates live so you can see whether the stock looks cheaper or richer. The discount rate starts at 10.0%, the figure our model used for UMC. Open Advanced to also change beta, growth and the rate path.
Note: no headline intrinsic value is published for this stock (the valuation is held for a data-quality reason — see the notes above). The calculator below is a what-if tool: the values it produces are your assumptions played out, not our estimate.
A full intrinsic value isn't shown for UMC because the valuation is currently held for a data-quality reason (see the guardrail notes above). The reverse-DCF reading still works — it needs only the price and cash flow — but we won't publish a forward value until the underlying data passes our checks.

⚙ Advanced — tinker with every input (beta, growth, rate path, margin → full intrinsic value)
A standard discounted cash flowDCF — Discounted Cash Flow — sums up all future cash a business will produce, adjusted for the fact that future dollars are worth less than dollars today.
Why it matters: It is the most fundamentally honest valuation method when applicable — but only works for companies with predictable, positive cash flow.
Reference: Best for: mature, profitable businesses. Fails for: pre-profit growth, banks, REITs.
Full explanation → (DCF) valuation is not meaningful for UMC because the model projects future cash flows from revenue trajectory due to negative free cash flowFree Cash Flow (FCF) — Operating cash flow minus capital spending: cash left after a company covers operating costs, taxes and interest and reinvests in the business — but BEFORE repaying debt principal or paying dividends. The cash actually available to investors.
Why it matters: A company can show big profits on paper while burning through cash. FCF is what actually fills the bank account.
Reference: Healthy mature businesses convert 8–15% of revenue into FCF · Growth companies often negative
Full explanation →, as indicated by the 'FCF negative' flag. Investors are likely betting on the company's ability to sustain and expand its gross margins, which have been expanding from 22.1% to 32.6%. The biggest risk to our assumptions is that the company's revenue, which has been roughly flat at 3% per year over four years, fails to accelerate or even declines, making future cash flow generation challenging.

Anatomy of a share
What you're buying per share. Bars are at the same scale so you can see the relative size of revenue, costs, cash flow, and debt — not just read them in a table.
What's free cash flow / what do these mean?
Revenue per share — how much the business earns from customers, divided by the number of shares outstanding. Top of the income statement.
Earnings per share — profit left after operating costs, interest, and taxes, per share. Two versions appear on this page and are not interchangeable: GAAP diluted EPS uses the company's weighted-average diluted share count during the reporting period (this is the "earnings" in "price-to-earnings"); net income per current share divides annual net income by today's share count. They differ whenever the share count has changed.
Owner-earnings free cash flow per share — the cash the business produces for shareholders. Savng's owner-earnings FCF subtracts capital expenditures and stock-based compensation from operating cash flow (SBC is a real dilution cost even though it's non-cash). This is deliberately more conservative than "standard" FCF, which subtracts only capital expenditures — so our figure is lower than the headline FCF you'll see elsewhere. FCF funds dividends, buybacks, debt repayment, and acquisitions; a company can report positive earnings yet negative FCF.
Debt per share — total interest-bearing borrowings divided by shares. High debt-per-share next to thin FCF-per-share is a fragility signal.
What you actually need to decide
Every stock price is a disagreement. Here's the single thing that must go right for the bulls, the single thing that breaks the thesis, and the concrete signposts to watch so you can update your view as real results arrive.
- Quarterly revenue growth rates
- Gross margin trends in upcoming earnings reports
- Announcements regarding new technology nodes or capacity expansion
The trend, in plain numbers (2023 → 2024)
Straight from the financial statements — no model, no opinion. For a small or unprofitable company, the direction of these numbers usually tells you more than any single valuation.
Nothing clearly improving year-over-year.
- Revenue fell -3% to $7.08B.
- Gross margin shrank to 33% (-2 pts).
- Net income fell -24% to $1.48B.

Revenue Drivers
Why Is It Priced Like This?
Why Customers Pay
What we use instead: earnings (P/E, EV/EBIT), book value (P/B) — computed from the figures this company does report, shown in the sections below. Those numbers are unaffected by the missing cash-flow data.
The market is likely pricing UMC based on its consistent profitability, having been profitable for 5 out of 5 years, and its expanding gross margin from 22.1% to 32.6%. The market may also be assigning value to the company's role in the global semiconductor supply chain, which is not in the model, given the strategic importance of chip manufacturing and potential for increased demand in various end markets.

Growth / Revenue DCF
No cash flow statement data available - using revenue/margin growth model as fallback.
Show advanced inputs
| RevenueGrowth | 3.0% |
What this model does NOT do: this is a consolidated owner-earnings FCF model. Standalone segment assumptions: none. It does not project product, services and recurring/cloud lines independently; their combined effect is embedded in the historical revenue and cash-flow trend the model extrapolates. The calculator above can only approximate a segment's impact through the single consolidated growth rate — it cannot model any one line separately. For a true segment-level view, build a separate model from the company's segment disclosures.
Maturity & Competitive Position
Moat Signals

These are timing signals, not value signals — they describe the stock's recent price behavior, not what the business is worth. Use them for the "the thesis looks good, but is now the moment?" question. Each tile below explains what it's saying.
Why it matters: Short-term contrarian indicator. Extreme readings often precede mean reversion, though not always.
Reference: 30–70 normal · >70 overbought · <30 oversold
Full explanation → (14)48.5NeutralMomentum is balanced — neither overbought nor oversold.
Why it matters: When the fast line crosses above the slow line, short-term momentum is turning up; below, turning down. A timing cue, not a value signal.
Reference: Line above signal = bullish momentum · below = bearish
Full explanation →BearishLine below signalThe fast trend is below the slow trend — short-term momentum is currently downward.
Technicals describe price, not the business. A great company can have a "bearish" tape (a buying chance) and a weak one a "bullish" tape (a trap). Pair these with the valuation and health sections above.
QUALITY
Data Quality & Risk Flags (5 notes — click to expand/collapse)
Guardrail Notes (5)
- FCF negative: revenue/margin growth model projects future cash flows from revenue trajectory.
- Terminal growth set to 2.4% — the lowest of the applicable caps (binding: 80% of near-term growth (3%)). We use one effective terminal rate everywhere on the page.
- Extreme valuation: the model output is implausibly high vs the price — usually a share-count or units error. The model value is suppressed.
- VALUATION HELD (EXTREME_MODEL_GAP): per-share values suppressed due to the model output failed plausibility checks.
- Extreme valuation gap (P/IV null): result may be dominated by model assumptions, share count issues, or sector-specific dynamics. Treat as low confidence.
