What matters now
- The price sits above even our optimistic bull case (1,277 IDR). The favourable scenario is already priced in.
- Weak quality (26/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.

38‑month range 1,750 IDR – 13,200 IDR · fair‑value band 765.99 IDR – 1,277 IDR · the 4,390 IDR price screens above the 1,021 IDR fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 23, 2026.
Analysis
PT Amman Mineral Internasional (AMMN) currently trades at 4,390 IDR, while our model-based Fair Value estimate is 1,021 IDR, implying the stock looks roughly 329.9% overvalued today. The Quality Score stands at 26/100 (below-average quality), in the Basic Materials sector. Bull case: the Multiples group reads highest at a median of 1,021 IDR per share, and 0 of the 11 models we run sit above the 4,390 IDR price. Bear case: the Earnings-Based group reads lowest at 510.66 IDR, and 11 of the 11 models stay below the price. Evidence for this calculation is low.
Over the trailing twelve months, PT Amman Mineral Internasional generated revenue of 2.7B IDR at a net margin of 20.7%. It earns a return on equity of 10.5%. Net debt stands at 5.5B IDR. The stock trades on a trailing P/E of 30.1. Fundamentals as of Aug 23, 2026
Our scenario range runs from 765.99 IDR (bear case) to 1,277 IDR (bull case); at 4,390 IDR, 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 52% below its 52-week high and 62% above its 52-week low, currently below its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at −50% fair-value upside, at −77%, AMMN screens richer than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly 99.21 IDR per share, which is 9.7 % 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.
All 11 models by family
Widest divergence: Multiples (1,021 IDR) versus Earnings-Based (510.66 IDR). Highest evidence: EPV (70).

Quality Score breakdown
Of which business quality 25 · Market factors (momentum, volatility) 32
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.
