Analysis

Sunrise Communications AG (SUNN) currently trades at CHF 42.26, while our model-based Fair Value estimate is CHF 96.91, implying the stock looks roughly 129.3% undervalued today. The Quality Score stands at 50/100 (solid quality), in the Communication Services 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: medium), always confirm before acting.

Over the trailing twelve months, Sunrise Communications AG generated revenue of CHF 3.0B at a net margin of -5.1%. Revenue grew 0.1% year over year. It earns a return on equity of -3.5%. Net debt stands at CHF 6.4B. Fundamentals as of Jul 18, 2026

Our scenario range runs from CHF 49.78 (bear case) to CHF 144.05 (bull case); at CHF 42.26, the current price sits below 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 11% below its 52-week high and 16% above its 52-week low, currently below its 200-day average. For context, the median of 10 Communication Services peers we cover trades at 32% fair-value upside, at 129%, SUNN 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.

Widest divergence: Multiples (CHF 136.20) versus Asset-Based (CHF 38.62). Highest evidence: Growth DCF (80).
