Citi analyst Jason Bazinet attributes the 8% pullback yesterday in shares of DISH (DISH) to the company's announced intent to offer $2B of convertible notes. The potential capital raise, when coupled with DISH's $3.5B of cash and a recent $1B bond offering at EchoStar, raises the total potential available cash across both entities to over $6.5B. The capital is unlikely to be used for a merger or acquisition since it is too small to facilitate a deal with most wireless carriers except Sprint (S), Bazinet tells investors in a research note. The analyst suspects the capital will be used for the current 600MHz auction. He thinks dilution from the capital raise will not be as bad as feared. The analyst keeps a Buy rating on DISH with a $94 price target.
