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 twelve-month earnings or share count in the filings yet
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. — Does not apply: no twelve-month earnings or share count in the filings yet
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. — Does not apply: no twelve-month earnings or share count in the filings yet
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. — Does not apply: no twelve-month earnings or share count in the filings yet
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. — No model applies: the filings don’t yet support a value.

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Profusa, Inc. with Health Care 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.

Consensus figures average analysts' published estimates (third-party data); guidance is the company's own. Neither is our forecast. Short interest is reported twice a month and lags. Market data may be delayed.

This section is general information, not investment advice or a personal recommendation, and it does not take account of your objectives or circumstances. Forecasts and guidance are estimates, not promises: companies miss their own guidance and analysts' figures are often revised. Prices can fall as well as rise, and you can lose money.
