The current case for continuing to hold
The stored model values McKesson Corporation at $831.05 per share against $994.58, versus $459.91 at the previous review on Oct 27, 2026. The case rests on the conditions below.
| Reason to hold | Supporting evidence | Contrary evidence | Condition to review |
|---|---|---|---|
| Revenue growth (yr 1): 13.39%Supported by the reviewed evidence | Trailing 4-year revenue CAGR of 13.4%, faded toward terminal growth over 5 years. | None in the last 45 days | Re-underwrite if revenue growth, margins, or the cost of capital diverge materially from the stored assumptions. |
| Operating margin (steady-state): 1.4%Supported by the reviewed evidence | Anchored to mean operating margin of 1.4% across the last 4 reported periods. | None in the last 45 days | Re-underwrite if revenue growth, margins, or the cost of capital diverge materially from the stored assumptions. |
| Discount rate (WACC): 10.44%Changed since the previous review | CAPM baseline: 4.94% risk-free + β1.00 × 5.5% ERP = 10.44%. | None in the last 45 days | Re-underwrite if revenue growth, margins, or the cost of capital diverge materially from the stored assumptions. |
