Analysis

Nephros, Inc (NEPH) currently trades at $4.21, while our model-based Fair Value estimate is $1.87, implying the stock looks roughly 55.6% overvalued today. The Quality Score stands at 66/100 (solid quality), in the Healthcare 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, Nephros, Inc generated revenue of $19.1M at a net margin of 4.1%. Revenue grew 6.9% year over year. It earns a return on equity of 7.8%. The balance sheet holds a net cash position of $4.3M. Fundamentals as of Jul 19, 2026

Our scenario range runs from $1.46 (bear case) to $2.34 (bull case); at $4.21, 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 34% below its 52-week high and 58% above its 52-week low, currently above its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -43% fair-value upside, at -56%, NEPH screens richer 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.

Model Bear Bear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull Bull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. Evidence
