Analysis

SDI Ltd (SDI) currently trades at A$1.40, while our model-based Fair Value estimate is A$1.60, implying the stock looks roughly 12.7% undervalued today. The Quality Score stands at 66/100 (solid quality), in the Healthcare sector. Bull case: the Growth Earnings group reads highest at a median of A$1.87 per share, and 15 of the 23 models we run sit above the A$1.40 price. Bear case: the Asset-Based group reads lowest at A$0.5800, and 8 of the 23 models stay below the price. Evidence for this calculation is high.

Over the trailing twelve months, SDI Ltd generated revenue of A$112M at a net margin of 10.4%. Revenue grew 2.7% year over year. It earns a return on equity of 11.6%. Net debt stands at A$8.4M. Fundamentals as of Aug 18, 2026

Our scenario range runs from A$1.10 (bear case) to A$2.28 (bull case); at A$1.40, 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 near its 52-week high and 74% above its 52-week low, currently above its 200-day average. For context, the median of 10 Healthcare peers we cover trades at −46% fair-value upside, at 14%, SDI screens cheaper than that median.

Fair Value models

This estimate rests on fiscal year 2025 figures, and about 12 months have passed since. In that time the company retained roughly A$0.0810 per share, which is 5.1 % 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.

Widest divergence: Growth Earnings (A$1.87) versus Asset-Based (A$0.5800). Highest evidence: FCF DCF (82).
