William Blair analyst Christopher Shutler notes that Walmart (WMT) and MoneyGram (MGI) announced a new service called "Walmart2World," which allows customers at U.S. Walmart locations to send money to any MoneyGram location in 200 countries. The analyst views this as a re-branding of an existing service, but with new pricing and in some cases maybe faster transfer times. While Shutler is not sure if Euronet (EEFT) formally bid on this business, the biggest issue he sees for the latter's stock is that this agreement shows a willingness on MoneyGram's part to play ball with Walmart on white-labeled products. The news arguably adds a little more uncertainty to the Euronet story, he contends.
