Verizon, the largest U.S. wireless carrier, hasn’t hired bankers to conduct an offer and there have been no formal talks, according to the report. Yahoo said last week that it would consider “strategic alternatives” for its core Internet business, even as it continues with its plan to revamp the business and spin it off. Yahoo’s core business, which includes popular services like Yahoo Mail and its news and sports sites, could attract private equity firms, media and telecom companies or firms like Softbank Group Corp (9984.T), analysts had said.
