Under the revised terms of the deal, Verizon's purchase the Yahoo assets will now total $4.48 billion. Yahoo still faces probes and lawsuits related to the breaches, which affected more than 1.5 billion accounts.
The transaction had been delayed due to the hacks.
Yahoo announced in September that hackers in 2014 stole personal data from more than 500 million of its user accounts. It admitted another cyber attack in December, this one dating from 2013, affecting more than a billion users.

Under the terms of the revised agreement, Yahoo will continue to cover the cost of a Securities and Exchange Commission probe into the breaches and shareholder lawsuits.
However, other government investigations and third-party litigation related to the breaches will be shared by Verizon and Yahoo.

"We have always believed this acquisition makes strategic sense," said Verizon executive vice president Marni Walden.
"We look forward to moving ahead expeditiously so that we can quickly welcome Yahoo's tremendous talent and assets into our expanding portfolio in the digital advertising space."
Prices of Yahoo shares rose 0.3 percent to $45.24, while Verizon gained 0.4 percent to $49.39.
