McKesson stock has delivered a very strong 336.0% return over the past five years, yet the current valuation checks and an intrinsic value estimate based on a Discounted Cash Flow (DCF) model both still point to the shares trading below their estimated worth.

Over 5 years, McKesson has returned 336.0%, which puts recent share price moves in the context of a long and very strong run.

Expectations for McKesson's ability to keep converting revenue into reliable cash flows can support the valuation. At the same time, any pressure on reimbursement terms or healthcare pricing may weigh on what investors are willing to pay.

Across the broader checks, McKesson screens as undervalued in 5 of 6 areas, which leans toward the stock being cheap rather than fully priced.

For investors, the debate is whether McKesson's recent share price still leaves enough gap to the intrinsic value estimate to justify viewing it as a potential undervaluation story.

Find out why McKesson's 19.3% return over the last year is lagging behind its peers.

The Discounted Cash Flow (DCF) approach values McKesson based on the cash it is expected to generate for shareholders over time. For McKesson, the model uses latest twelve month free cash flow of about $6.0b and assumes that cash flows keep growing rather than shrinking. On that basis, the 2 Stage Free Cash Flow to Equity model points to an estimated intrinsic value of about $1,675 per share.

Compared with the current market price, this DCF estimate implies the stock trades at roughly a 49.9% discount to its calculated worth. The model therefore suggests McKesson stock screens as undervalued, with the market price not fully reflecting the level and projected growth of its cash generation.

On these cash flow projections, McKesson appears undervalued relative to the DCF based intrinsic value estimate.
