If you haven’t read the guide to the 10-Minute Investment Autopsy series, you can find it here. You will get the most out of each case if you:

  • Pause after the “Original Thesis” section and think about what you would have done

  • Engage with the discussion questions and other members in the weekly thread designed to help you further improve your investing process

The Original Thesis

Who: John Lewis

When: March 2005

What: eDiets.com (ticker: DIET)

The Thesis:

  • Company transforms the underlying principles of the diet programs that it licenses into an online diet service

  • Users pay $5/week for customized meal plans, grocery lists, access to experts and exercise programs

  • Revenues have grown from $5M in 1999 to a $55M run-rate in 2005

  • Most visited website for health, nutrition and fitness with ~ 5M visitors per month and 200K paying customers

  • Market believes the business model is broken because of enormous advertising spend to acquire new customers

  • New COO brought in last month who has the potential to turn things around

  • Company moving away from 100% internet ads and diversified into onsite spending at grocery stores, TV and strategic partnerships

  • Europe presents a big source of upside with Tesco and Europe’s Wal-Mart owning a 15-year license based on a royalty model

  • Stock is cheap at 1.1 EV/Sales vs. peer group multiple of 3.5x

  • If they can show substantial growth while lowering subscriber acquisition costs, the company can get to operating margins in the low teens

  • eDiets.com has high value to a potential strategic acquirer at a price that is 2x-2.5x where the stock is trading

  • Worst case scenario is that they can’t get acquisition costs under control, in which case they slash the budget and generate a lot of cash flow with downside to the stock at less than 30%
