Valuation

Silicon Motion Technology Corp valuation models and calculator

Fundamentalytics rating

model v1.6 · 2026-11-03

Not rated: held for review: our cash-flow value ($34.12) was left out of our combined valuation (it is 0.17x 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 Silicon Motion Technology Corp's free cash flow after stock-based pay ( $50.6M, FY2025 Q4 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 Silicon Motion Technology Corp as an operating company, with every model that fits that kind of business. Cost of equity 13%: the 10-year Treasury yield (4.9%) plus a beta of 1.78 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. ~$34 ~$27–$43 Left out: out of range vs price (0.18x)
Growth cash-flow model Revenue for this year and next from analysts' consensus, then growth fading to 2.5%; the operating margin moving to profitable peers'; investment needed per dollar of growth from peers; reduced by a failure probability.

Uses analysts' consensus estimates (third-party data), not our forecasts. ~$250 ~$150–$350 Left out: far from the other models (more than 3x away from their median)
Price-to-earnings vs peers Earnings per share times peers' typical (harmonic-mean) price-to-earnings. ~$29 ~$64–$150 Left out: out of range vs price (0.16x)
