Data I/o Corp valuation models and calculator

Fundamentalytics rating

model v1.6 · 2026-11-03

Not rated: only 1 valuation models apply; a rating needs 3.

Valuation models

We value Data I/o Corp as an operating company, with every model that fits that kind of business. Cost of equity 9.9%: the 10-year Treasury yield (4.9%) plus a beta of 1.1 times a 4.5% equity risk premium.

Value per share by model
Model Value per share In the combined value?
Price-to-earnings vs peers Earnings per share times peers' typical (harmonic-mean) price-to-earnings. — Does not apply: no positive earnings in the latest twelve months
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. — Does not apply: the model gives no positive value
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. — Does not apply: return on equity is not positive
Revenue-to-maturity model Revenue grown to maturity with the cash margin moving to the industry's; for companies not yet profitable. — Does not apply: revenue and margins don't support a positive value
Price-to-sales vs peers Sales per share times peers' typical price-to-sales; used only when earnings are negative. ~$0.7 ~$1.8–$9.0 Included, half weight
Combined value Weighted average of the models that apply: the primary model (price-to-earnings vs peers) counts double. Models more than 5x or less than 0.2x the share price, or more than 3x away from the other models' median, are left out. ~$0.7 ~$0.7–$9.0 1 model

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Data I/o Corp with Electronic Equipment & Instruments in our coverage, using third-party market data. Model values are estimates under stated assumptions, updated as new filings arrive; not price targets or investment advice. How each model works.

Moat

56 /100

Moderate moat

How hard Data I/o'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 20 / 20

    Cash operating profit has been a median 22.6% of total assets over 10 years.

  • Pricing power 18 / 20

    Gross margin has been a median 55.1%, moving by 3.0 percentage points (standard deviation) across 10 years.

  • Durability 10 / 20

    Operating margin has been a median -6.5%; its worst year was -43.7%.

  • Cash conversion 4 / 20

    Free cash flow was positive in 4 of 10 years, at a median -0.9% of revenue.

  • Discipline 9 / 20

    The diluted share count rose 13.4% over five years; stock-based pay has been a median 4.3% 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 (61 before it).
