We value Polar Power, Inc. as an operating company, with every model that fits that kind of business. Cost of equity 10.9%: the 10-year Treasury yield (4.9%) plus a beta of 1.33 times a 4.5% equity risk premium.
| 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. | — | Does not apply: revenue and margins don't support a positive 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 |
| Price-to-sales vs peers Sales per share times peers' typical price-to-sales; used only when earnings are negative. | ~$0.1 ~$0.7–$5.7 | Included, half weight |
| 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. | ~$0.1 ~$0.1–$5.7 | 1 model |
