Verizon reportedly is close to a deal to buy the core Web assets of Yahoo for $5 billion, which would end a months-long process of jockeying over the future of the struggling company. Verizon emerged as the winner of a lengthy bidding contest to acquire the assets, according to reports that surfaced Friday. An agreement is expected early next week. The deal itself could take six to nine months to finalize. The acquisition price is rumored to be $5 billion. The deal would include real estate but not the company’s intellectual property portfolio.
