What matters now
- A high-quality business (quality 76/100), yet the market already pays well above fair value. Quality at a full price, with little margin of safety.
- The price sits above even our optimistic bull case ($64.17). The favourable scenario is already priced in.
- A fairly wide model range ($34.07 to $64.17) leaves room in how you read the outcome.

How to read this chart
60‑month range $19.24 – $170.66 · fair‑value band $34.07 – $64.17 · the $84.34 price screens above the $51.59 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Sep 3, 2026.
Analysis
Rambus Inc (RMBS) currently trades at $84.34, while our model-based Fair Value estimate is $51.59, implying the stock looks roughly 63.5% overvalued today. The Quality Score stands at 76/100 (high quality), in the Technology sector. Bull case: the DCF Models group reads highest at a median of $67.99 per share, and 0 of the 26 models we run sit above the $84.34 price. Bear case: the Asset-Based group reads lowest at $8.45, and 26 of the 26 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Rambus Inc generated revenue of $721M at a net margin of 31.9%. Revenue grew 8.1% year over year. It earns a return on equity of 18.0%. The balance sheet holds a net cash position of $139M. Fundamentals as of Sep 3, 2026
Our scenario range runs from $34.07 (bear case) to $64.17 (bull case); at $84.34, 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 45% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at −59% fair-value upside, at −39%, RMBS screens cheaper 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 $1.42 per share, which is 2.8 % 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: DCF Models ($67.99) versus Dividend Discount ($1.59). Highest evidence: FCF DCF (76).

Quality Score breakdown
Of which business quality 76 · Market factors (momentum, volatility) 23
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.
