Merck & Co., Inc. is worth about $102.23 per share against a $145.95 price (-30%), so the shares look Overvalued. — Market Ontology published valuation, Oct 17, 2026
| Statement | Type | Evidence or calculation | Assessment |
|---|---|---|---|
| The latest annual filing is dated 2025-11-05. | Reported fact | SEC EDGAR (via Polygon) | Supported by SEC EDGAR (via Polygon), covering the filing dated 2025-11-05. |
| The discount rate is 6.10%. | Calculation | 5.1% risk-free + 0.13 beta × 5.5% equity risk premium | The supplied inputs produce 5.82%; the argument states 6.10%. |
| Revenue grows -8.84% in year one, fading to 2.55%. | Forecast | Trailing 4-year revenue CAGR of -8.8%, faded toward terminal growth over 5 years. | This result requires revenue growth (yr 1) of -8.84% over 5 years. |
| The shares look Overvalued. | Proposed action | Model value vs price (-30%) | A valuation difference is not a predicted return. The recommendation does not specify a holding period or maximum position size, which are needed to assess the decision. |
Does the argument survive a different assumption?
Changing discount rate from 6.10% to 7.10% changes calculated value per share from $102.23 to $77.99.
The model value stays on the same side of the $145.95 price, so the conclusion survives this change.
