Not rated: only 2 valuation models apply; a rating needs 3.

Valuation models

We value CDT Environmental Technology Investment Holdings Ltd as an operating company, with every model that fits that kind of business. Cost of equity 9.9%: the 10-year Treasury yield (4.9%) plus a beta of 1.11 times a 4.5% equity risk premium.

Value per share by model
Model Value per share In the combined value?
Revenue-to-maturity model Revenue grown to maturity with the cash margin moving to the industry's; for companies not yet profitable. ~$0.3 ~$0.3–$0.5 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. — 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. ~$3.3 ~$2.3–$5.0 Included
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. ~$3.3 ~$2.9–$3.9 Included
Price-to-sales vs peers Sales per share times peers' typical price-to-sales; used only when earnings are negative. ~$0.7 ~$0.6–$6.6 Left out: far from the other models (more than 3x away from their median)
Combined value Weighted average of the models that apply: the primary model (revenue-to-maturity 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. ~$3.3 ~$3.3–$3.3 2 models

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare CDT Environmental Technology Investment Holdings Ltd with Environmental & Facilities Services in our coverage, using third-party market data.
