Analysis
United Microelectronics Corporation (UMC) currently trades at $19.38, while our model-based Fair Value estimate is $21.89, implying the stock looks roughly 13.0% undervalued today. The Quality Score stands at 65/100 (solid quality), in the Technology sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: high), always confirm before acting.
Over the trailing twelve months, United Microelectronics Corporation generated revenue of $241B at a net margin of 20.8%. Revenue grew 5.5% year over year. It earns a return on equity of 12.5%. The balance sheet holds a net cash position of $50.9B. Fundamentals as of Aug 13, 2026
Our scenario range runs from $15.07 (bear case) to $29.69 (bull case); at $19.38, the current price sits within that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 18% below its 52-week high and 195% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -54% fair-value upside, at 13%, UMC screens cheaper than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
All 25 models by family
Widest divergence: Growth Earnings ($377.04) versus Asset-Based ($101.40). Highest evidence: Growth DCF (80).

A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
