Analysis
Rion Co (RIOXF) currently trades at $14.63, while our model-based Fair Value estimate is $26.20, implying the stock looks roughly 79.1% undervalued today. The Quality Score stands at 64/100 (solid quality), in the Healthcare sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: high), always confirm before acting.
Over the trailing twelve months, Rion Co generated revenue of $28.5B at a net margin of 11.7%. Revenue grew 7.6% year over year. It earns a return on equity of 10.1%. The stock trades on a trailing P/E of 9.3. Fundamentals as of Jul 21, 2026
Our scenario range runs from $18.34 (bear case) to $35.95 (bull case); at $14.63, the current price sits below 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 26% below its 52-week high and 7% above its 52-week low, currently above its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -22% fair-value upside, at 79%, RIOXF 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.
All 24 models by family
