The Fundamentalytics view

Next results ~February 4, 2027 (estimated)

Impinj Inc's trailing-twelve-month revenue grew 7.7% year on year, with a free-cash-flow margin of 16.9%. Where it stands out: gross margin of 53.5% ranks 2 of 24 electronic components companies we cover. Where it lags: stock pay as % of revenue of 16.1% ranks 22 of 24 electronic components companies we cover.

Our discounted-cash-flow model values the business at ~$27 per share in the base case (~$20–$37 across growth scenarios) — model values under stated assumptions, not a price target.

Current signal Free cash flow diverging from earnings: TTM free cash flow grew 61.0% while net income grew 23.4%: a 38pp divergence.

Assembled from SEC-filed figures — the full workings are on this page and in our methodology. Observations, not recommendations.

Highlights

How we pick these

Strengths

  • Growth speeding up. The growth rate is 4.2 points higher than a quarter earlier.

Things to watch

  • Loss-making. Operating margin is -0.7%: costs exceed revenue.
  • Heavy stock-based pay. Stock pay equals 16.1% of revenue, against a median of 2.1% for electronic components companies we cover: a real cost that cash-flow figures leave out.
  • Share dilution. Diluted shares rose 6.4% in a year.
  • High sales multiple. The shares trade at 15 times revenue while operating margins remain thin.
  • Volatile shares. Over the past year the shares showed annualised volatility of 68% and a beta of 2.1 against the S&P 500.
  • Insiders selling. 4 insiders sold $188M of stock over the past 365 days and none bought (1% under pre-set trading plans).

Valuation

Impinj Inc valuation models and calculator

Fundamentalytics rating

model v1.6 · 2026-11-03

Not rated: held for review: our cash-flow value ($27.36) was left out of our combined valuation (it is 0.15x the share price, outside the 0.2-5x range we accept), so it can't be the basis of a rating.

Our value per share comes from a discounted-cash-flow model of Impinj Inc's free cash flow after stock-based pay ( $16.5M, FY2026 Q3 TTM, with after-tax interest added back): growth for five years as below (the first two years from forecasts, guidance and the company's record), fading to 2.5%, discounted at 8.5%, then cash added and debt and other claims subtracted. These are model values under stated assumptions, not price targets or recommendations.

The inputs used by the models below have passed source checks. Individual model values are available below and in the interactive valuator. Their differences are shown explicitly; the platform combined value and recommendation remain withheld.

Valuation models

We value Impinj Inc as an operating company, with every model that fits that kind of business. Cost of equity 11.9%: the 10-year Treasury yield (4.9%) plus a beta of 1.55 times a 4.5% equity risk premium.

Cash-flow model (DCF) Free cash flow to the firm (after stock pay, with after-tax interest added back), grown then faded to 2.5%, discounted at 8.5% as the firm rate, less debt and other claims. ~$27 ~$20–$37 Left out: out of range vs price (0.15x)
Forward price-to-earnings vs peers Next year's consensus earnings per share times peers' typical (harmonic-mean) forward price-to-earnings. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$53 ~$42–$79 Included
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. — Does not apply: This model is withheld pending its input or assumption review.
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. — Does not apply: This model is withheld pending its input or assumption review.

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Impinj Inc with Electronic Components in our coverage, using third-party market data.

Moat

36 /100

Weak moat

How hard Impinj's competitive advantage looks for rivals to wear away, judged from 10 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.

  • Returns on capital 10 / 20

    Cash operating profit has been a median 8.4% of total assets over 10 years.

  • Pricing power 17 / 20

    Gross margin has been a median 50.8%, moving by 2.4 percentage points (standard deviation) across 10 years.

  • Durability 10 / 20

    Operating margin has been a median -10.4%; its worst year was -33.3%.

  • Cash conversion 4 / 20

    Free cash flow was positive in 4 of 10 years, at a median -3.4% of revenue.

  • Discipline 0 / 20

    The diluted share count rose 28.3% over five years; stock-based pay has been a median 15.4% of revenue.

AI disruption exposure: Medium. In this industry, AI could change how the product is made or sold, without replacing the core asset. The score above includes a 5-point deduction for that exposure (41 before it).
