Fair value as of: Aug 13, 2026

From 26 valuation models · updated yesterday

Fair value updated Aug 13, 2026, revised from $77.46 to $76.00 (−1.9%) since Jul 18, 2026. Share price −14.5% over the past month.

A solid business, but screening 75% overvalued on our models.

What matters now

  • The price sits above even our optimistic bull case ($147.50). The favourable scenario is already priced in.
  • The model range is unusually wide ($33.52 to $147.50). The outcome hinges heavily on assumptions, so read the point estimate with caution.
  • Solid but not exceptional quality (57/100) and above fair value, neither a clear bargain nor a standout compounder.

Analysis

MKS Inc (MKSI) currently trades at $306.29, while our model-based Fair Value estimate is $76.00, implying the stock looks roughly 75.2% overvalued today. The Quality Score stands at 57/100 (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, MKS Inc generated revenue of $4.1B at a net margin of 8.0%. Revenue grew 15.2% year over year. It earns a return on equity of 12.7%. Net debt stands at $4.0B. Fundamentals as of Aug 13, 2026

Our scenario range runs from $33.52 (bear case) to $147.50 (bull case); at $306.29, 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 last reported earnings sit well below what analysts expect (earnings in transition, for example after write-downs or an earnings dip); whether the stock is cheap or expensive hinges on the expected recovery actually arriving. Read the fair value with that caveat. The share trades about 10% below its 52-week high and 248% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -46% fair-value upside, at -75%, MKSI 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
