We value ONE Nuclear Energy Inc. as an utility or power producer, with every model that fits that kind of business. Cost of equity 7.1%: the 10-year Treasury yield (4.9%) plus a beta of 0.48 times a 4.5% equity risk premium.

Value per share by model
Model Value per share In the combined value?
Utility earnings model Net income growing 3% a year, discounted at 8%: for regulated investment that makes free cash flow negative. — Does not apply: net income is not positive
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
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
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
Dividend discount (two-stage) Dividends for five years at the growth the business can fund, then a steady payout and growth. — 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 (utility earnings 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. — 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 ONE Nuclear Energy Inc. with utilities and power producers 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.
