Fundamentalytics rating

model v1.6 · 2026-11-03

Not rated: valued with our growth model, which doesn't carry a Buy/Hold/Sell rating yet.

Valuation models

We value Amprius Technologies, Inc. as an operating company, with every model that fits that kind of business. Cost of equity 12.7%: the 10-year Treasury yield (4.9%) plus a beta of 1.73 times a 4.5% equity risk premium.

Value per share by model
Model Value per share In the combined value?
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. For young or fast-growing companies. The starting margin is normalized to between -100% and 60%; net margin is a proxy when operating income is not tagged. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$1.6 ~$0.7–$2.3 Left out: out of range vs price (0.19x)
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. ~$1.8 ~$1.4–$2.5 Included
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
Forward price-to-sales vs peers Next year's consensus sales per share times peers' typical forward price-to-sales; only when earnings are negative. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$1.7 ~$1.6–$5.6 Included, half weight
Revenue-to-maturity model Revenue grown to maturity with the cash margin moving to the industry's; for companies not yet profitable. ~$0.1 Left out: out of range vs price (0.01x)
Combined value Weighted average of the models that apply: the primary model (growth cash-flow model) 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. ~$1.8 ~$1.7–$1.8 2 models

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Amprius Technologies, Inc. with Electrical Components & Equipment 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.

  • Pricing power 0 / 20
