Yahoo shareholders approved the US$4.48b (NZ$6.1b) sale of the company's main web properties to Verizon Communications, clearing the last major hurdle for a deal announced almost a year ago.

The company expects to hand over its web assets to the telecommunications giant on June 13, according to a statement Thursday. The transaction had earlier been delayed by revelations of massive privacy breaches and a reduction in the price from $4.8b (NZ$6.6b).

Yahoo Chief Executive Officer Marissa Mayer agreed to the sale last year after a four-year turnaround effort failed to stem a slide in advertising revenue.

Verizon will seek to use Yahoo's web audience to push deeper into content and expand beyond its central business of connecting people to the internet, cable channels and their smartphones.


Yahoo will become part of a new Verizon unit called Oath that will include media content and digital services like email. The division will also incorporate businesses Verizon added when it bought AOL, another faded internet pioneer, for US$4.4b (NZ$6.1b) in 2015.

Last year, the deal was thrown into question after the Sunnyvale, California-based web portal revealed widespread cyber attacks during Mayer's tenure that exposed hundreds of millions of users' online information.

In September, Yahoo disclosed a 2014 breach that affected at least 500 million customer accounts. Then, the company said in December that hackers in 2013 siphoned information including users' e-mail addresses, scrambled account passwords and dates of birth. In February, Yahoo and New York-based Verizon agreed to drop the purchase price by $350m (NZ$485m).

What remains of Yahoo after the sale, when the will be renamed Altaba, will be the most valuable parts of the current company: stakes in China's Alibaba Group Holding and Yahoo Japan that are worth more than $40 billion. Altaba, which will be led by current Yahoo director Thomas McInerney, will share ongoing legal responsibilities related to the security breaches.
