Analysis

Singapore Telecommunications Limited (Z77) currently trades at 4.53 SGD, while our model-based Fair Value estimate is 3.03 SGD, implying the stock looks roughly 49.5% overvalued today. The Quality Score stands at 61/100 (solid quality), in the Communication Services sector. Bull case: the Growth Earnings group reads highest at a median of 5.68 SGD per share, and 4 of the 20 models we run sit above the 4.53 SGD price. Bear case: the Growth DCF group reads lowest at 0.8400 SGD, and 16 of the 20 models stay below the price. Evidence for this calculation is high.

Over the trailing twelve months, Singapore Telecommunications Limited generated revenue of 14.3B SGD at a net margin of 39.3%. Revenue grew 4.6% year over year. It earns a return on equity of 20.6%. Net debt stands at 8.2B SGD. Fundamentals as of Aug 13, 2026

Our scenario range runs from 2.27 SGD (bear case) to 3.78 SGD (bull case); at 4.53 SGD, the current price sits above 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 14% below its 52-week high and 23% above its 52-week low, currently below its 200-day average. For context, the median of 10 Communication Services peers we cover trades at 30% fair-value upside, at −33%, Z77 screens richer than that median.

Fair Value models

This estimate rests on fiscal year 2026 figures, and about 5 months have passed since. In that time the company retained roughly 0.0667 SGD per share, which is 2.2 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.

Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced 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. Every input is real reported data, nothing guessed.

Model Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. Evidence

Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.

All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
