What matters now
- The rarer combination: high quality (71/100) AND below fair value. That earns a closer look rather than a quick verdict.
- A fairly wide model range ($11.04 to $26.76) leaves room in how you read the outcome.
Price vs Fair Value (5 years)
White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Aug 21, 2026.
How to read this chart
60‑month range $6.51 – $13.45 · fair‑value band $11.04 – $26.76 · the $12.85 price screens below the $18.10 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). 3 fiscal years are left out: there the valuation rested on only a fraction of the usual models. Dashed = 300-day average. As of Aug 21, 2026.
Analysis
Star Gas Partners LP (SGU) currently trades at $12.85, while our model-based Fair Value estimate is $18.10, implying the stock looks roughly 29.0% undervalued today. The Quality Score stands at 71/100 (solid quality), in the Energy sector. Bull case: the Multiples group reads highest at a median of $33.74 per share, and 21 of the 25 models we run sit above the $12.85 price. Bear case: the Asset-Based group reads lowest at $6.19, and 4 of the 25 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Star Gas Partners LP generated revenue of $1.9B at a net margin of 5.3%. Revenue grew 3.2% year over year. It earns a return on equity of 24.9%. Net debt stands at $261M. Fundamentals as of Aug 21, 2026
Our scenario range runs from $11.04 (bear case) to $26.76 (bull case); at $12.85, 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 5% below its 52-week high and 21% above its 52-week low, currently above its 200-day average. For context, the median of 10 Energy peers we cover trades at −59% fair-value upside, at 41%, SGU screens cheaper than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 11 months have passed since. In that time the company retained roughly $1.69 per share, which is 9.3 % 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 25 models by family
Widest divergence: Multiples ($33.74) versus Asset-Based ($6.19). Highest evidence: FCF DCF (78).

Quality Score breakdown
Of which business quality 66 · Market factors (momentum, volatility) 65
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.
