The T-Mobile-Sprint merger looked like it was pretty much a done deal a couple of weeks ago, when DoJ gave its approval. It now looks like there won’t be a final answer until 2020. This will go down in history as one of the longest corporate merger attempts. The delay will be hardest on Sprint and Dish. Even though T-Mobile looks stronger, it needs the deal too, as it transitions into 5G. The good news for T-Mobile is that a recent earnings report shows continuing growth — but that also means regulators may not see this merger as necessary.
