If you haven’t read the guide to the 10-Minute Investment Autopsy series, you can find it here.

The Original Thesis

Who: Larry Robbins

When: October 2005

What: McKesson (ticker: MCK)

The Thesis:

  • Drug distributors are the choke point in the value chain, with the top 3 controlling 90% market share

  • Business model has changed from speculating on inventory to fee for service, resulting in much lower capital intensity and a higher conversion from Net Income to FCF

  • McKesson is a share taker in the industry

  • Company will benefit from higher drug utilization and higher generic penetration

  • Thinks the company will earn $3 in EPS in Fiscal 2007, 10% above Wall Street estimates

  • Believes McKesson will grow 20%-25% through 2008 and then 12%-15% from there

  • At 15x EPS, the stock is trading at a discount to the market which is too cheap for a business that is hitting on all cylinders for the next few years

What Happened (Just the Facts)

  • McKesson stock meaningfully beat the market, with the stock increasing at ~9%+ per year over the 5-year period, compared to the market at 2%

  • Compared to the other two drug distributors, Cardinal Health and AmerisourceBergen, it did much better than the former but not as well as the latter
