Valuation models

We value Onconetix, Inc. as an operating company, with every model that fits that kind of business. Cost of equity 11%: the 10-year Treasury yield (4.9%) plus a beta of 1.34 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. ~$0.2 ~$0.5–$1.6 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. ~$0.2 ~$0.2–$1.6 1 model

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Onconetix, Inc. with Biotechnology in our coverage, using third-party market data.

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.
