McKesson (MCK) Stock May Be 37% Undervalued On Raised Full Year Guidance

Listen to the news

McKesson has ridden a powerful multi‑year run, and the current share price now puts a spotlight on a simple question for investors: Do the company’s underlying cash flows support where the stock trades today, or has sentiment moved faster than the money it generates?

  • Over the past 5 years the stock has returned 393.6%, which puts a lot of accumulated optimism on the line when you test the price against what the business can realistically produce in cash over time.
  • Recent earnings outperformance and higher full year profit expectations can feed into stronger projected cash generation, which may support a richer valuation if those cash flows prove durable.
  • What if you looked at McKesson through its earnings instead? See what McKesson's 26.3x P/E says about the price.

The issue now is whether McKesson’s current market value is justified by the stream of cash flows that its operations are expected to deliver.

Does McKesson Look Undervalued on Cash Flow?

The Discounted Cash Flow (DCF) model takes McKesson’s future cash flows and discounts them back into today’s dollars. On the latest figures, the business generated last twelve month free cash flow of about $6.7b, and analyst projections in the model point to growing cash generation over the coming decade rather than a shrinking stream.

Those rising cash flow assumptions are paired with a share price of $1,072.00. The DCF output suggests this price is below the value implied by the projected cash being returned to equity holders. Because McKesson recently beat Q2 earnings expectations and raised full year guidance, stronger profit delivery helps explain why the cash flow outlook used in the model supports an intrinsic value that sits substantially above where the stock trades today.
