After calling off a merger in November 2017, T-Mobile seems to be looking to merge with Sprint again. The merger was called off due to the idea that they were unable to come to terms with a mutually beneficial deal, but according to Yahoo, they have found terms that work for both parties. The deal could be announced this weekend.
T-Mobile would have a minority equity stake in the company while having a majority voting power.
Commentary: I am concerned that if you take two lower-end telecommunication (out of the top 4) and merge them together will only make a weaker third option as opposed to a strong third option. If AT&T or Verizon was going to consume one of the lower-end companies, the customers on the smaller service would actually get better service.
