Brookfield Infrastructure Partners LP has agreed to acquire Hotwire Communications LLC in a transaction that values the Florida-based internet-service provider at about $7 billion, including debt, according to people familiar with the matter. The purchase will give the Canadian investment firm a larger foothold in next-generation broadband infrastructure, a sector benefiting from rising demand for high-speed connectivity in the United States. Separately, Brookfield is in advanced talks to sell a Brazilian power transmission line to a consortium comprising China’s State Grid Corp. and Colombia’s Grupo Energía Bogotá, sources said. Terms of the potential sale were not disclosed, and discussions could still fall through, but the move signals Brookfield’s continued portfolio rotation between digital and energy infrastructure assets.
