Analysis

Rambus Inc (RMBS) currently trades at $97.68, while our model-based Fair Value estimate is $37.62, implying the stock looks roughly 61.5% overvalued today. We read business quality at 63/100 (solid quality), in the Technology sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: 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 Jul 12, 2026

Our scenario range runs from $28.54 (bear case) to $53.17 (bull case); at $97.68, 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 44% below its 52-week high and 68% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -62% fair-value upside, at -61%, RMBS screens cheaper than that median.

Fair Value models

Each model estimates fair value its own way; the Fair Value above is the evidence-weighted 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.

Widest divergence: DCF Models ($57.06) versus Dividend Discount ($1.59). Highest evidence: Growth DCF (80).
