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

Valuation models

We value Natural GAS Services Group Inc as an operating company, with every model that fits that kind of business. Cost of equity 9.8%: the 10-year Treasury yield (4.9%) plus a beta of 1.09 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. ~$29 ~$24–$49 Primary model, counts double
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. ~$9.1 ~$5.9–$14 Included
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. ~$1.5 ~$1.3–$1.8 Left out: out of range vs price (0.05x)
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: earnings are positive: price-to-earnings is the better measure
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. ~$22 ~$9.1–$29 2 models

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Natural GAS Services Group Inc with Oil & Gas Equipment & Services in our coverage, using third-party market data.
