Charter Communications is facing heightened competition from Verizon and T-Mobile’s wireless home internet products, and the cable company could soon lose even more subscribers when a key government program runs out of funding in April, JPMorgan analysts say in a research note. Charter’s 4Q results revealed a surprisingly steep loss of broadband subscribers, the analysts note. They add that the end of the Affordable Connectivity Program, which gave $30 a month to eligible customers to put toward their internet bills, could hurt Charter more than its peers. They cut their rating on the stock to neutral. Shares fall 3.1%.
