| Model | Value per share | In the combined value? |
|---|---|---|
| Growth cash-flow model Revenue for this year and next from analysts' consensus, then growth fading to 2.5%; the operating margin moving to profitable peers'; investment needed per dollar of growth from peers; reduced by a failure probability. For young or fast-growing companies. The starting margin is normalized to between -100% and 60%; net margin is a proxy when operating income is not tagged. Uses analysts' consensus estimates (third-party data), not our forecasts. | ~$28 ~$20–$34 | Primary model, counts double |
| 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 |
| Forward price-to-sales vs peers Next year's consensus sales per share times peers' typical forward price-to-sales; only when earnings are negative. Uses analysts' consensus estimates (third-party data), not our forecasts. | ~$17 ~$16–$49 | Included, half weight |
| 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 |
| Combined value Weighted average of the models that apply: the primary model (growth cash-flow 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. | ~$25 ~$17–$28 | 2 models |
