What matters now

• The price sits above even our optimistic bull case ($17.96). The favourable scenario is already priced in.
• Solid but not exceptional quality (54/100) and above fair value, neither a clear bargain nor a standout compounder.
• A fairly wide model range ($9.01 to $17.96) 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 19, 2026.

How to read this chart

60‑month range $5.78 – $36.93 · fair‑value band $9.01 – $17.96 · the $24.63 price screens above the $12.18 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). 1 fiscal year is left out: there the valuation rested on only a fraction of the usual models. Dashed = 300-day average. As of Aug 19, 2026.

Analysis

Magnite Inc (MGNI) currently trades at $24.63, while our model-based Fair Value estimate is $12.18, implying the stock looks roughly 102.2% overvalued today. The Quality Score stands at 54/100 (solid quality), in the Communication Services sector. Bull case: the Growth Earnings group reads highest at a median of $26.72 per share, and 7 of the 26 models we run sit above the $24.63 price. Bear case: the Asset-Based group reads lowest at $4.32, and 19 of the 26 models stay below the price. Evidence for this calculation is high.

Over the trailing twelve months, Magnite Inc generated revenue of $723M at a net margin of 22.0%. Revenue grew 5.5% year over year. It earns a return on equity of 19.1%. Net debt stands at $73.0M. Fundamentals as of Aug 19, 2026

Our scenario range runs from $9.01 (bear case) to $17.96 (bull case); at $24.63, 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 8% below its 52-week high and 128% above its 52-week low, currently above its 200-day average. For context, the median of 10 Communication Services peers we cover trades at −13% fair-value upside, at −51%, MGNI 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 $0.7134 per share, which is 5.9 % 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 ($26.72) versus Dividend Discount ($0.3700). Highest evidence: FCF DCF (76).
