The Original Thesis

Who: Bill Miller and me

When: June 2005 and June 2006

What: Sprint Nextel (ticker: S)

The Thesis:

  • Economics of telecom are undergoing rapid change

  • The market is underestimating the benefits of wireless consolidation to a structure where 3 players are controlling 75% market share

  • Sprint Nextel is the 3rd largest wireless company and overall telecom provider in the U.S.

  • The company has a differentiated product offering with a clear technology path

  • Cost cutting synergies from the merger should be north of $500M per year

  • Bill bought more shares after Sprint Nextel shares declined post-merger in 2006

  • He did not believe that things had changed and therefore perceived the lower price increased his future IRR

  • He believed that the market was too focused on short-term operating metrics and that progress at the company would be non-linear

  • The shares, at 5.5x EV/EBITDA are trading at a big discount to other subscription-based companies whose stocks trade in the 8-9x range

  • In June 2006 Bill believed that Sprint’s private market value, conservatively estimated, was 50%+ above the then-current price
