What matters now
- Solid quality (48/100) at a price below fair value, the discount is the argument here, not the business quality.
- A fairly wide model range ($54.89 to $135.57) leaves room in how you read the outcome.

Analysis
Delta Air Lines Inc (DAL) currently trades at $78.75, while our model-based Fair Value estimate is $96.56, implying the stock looks roughly 18.4% undervalued today. The Quality Score stands at 48/100 (below-average quality), in the Industrials sector. Bull case: the Growth Earnings group reads highest at a median of $143.98 per share, and 18 of the 26 models we run sit above the $78.75 price. Bear case: the Dividend Discount group reads lowest at $10.38, and 8 of the 26 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Delta Air Lines Inc generated revenue of $65.2B at a net margin of 6.9%. Revenue grew 12.9% year over year. It earns a return on equity of 25.0%. Net debt stands at $16.8B. Fundamentals as of Aug 31, 2026
Our scenario range runs from $54.89 (bear case) to $135.57 (bull case); at $78.75, 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 6% below its 52-week high and 76% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at 59% fair-value upside, at 23%, DAL 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 $3.44 per share, which is 3.6 % 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 26 models by family
Widest divergence: Growth Earnings ($143.98) versus Dividend Discount ($10.38). Highest evidence: FCF DCF (78).

Quality Score breakdown
Of which business quality 48 · Market factors (momentum, volatility) 60
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.
