Verizon has taken over Yahoo, completing a $4.5 billion deal that marks the end of the Yahoo’s 21-year-old history as a publicly traded company and the five-year reign of Yahoo CEO Marissa Mayer. Tuesday’s closure of sale will result in a new management team as the company moves to bring in greater advertising revenue from one of the internet’s best-known brands.

CEO Mayer will not be joining Verizon and will walk away from Yahoo with a compensation package currently worth about $127 million, including her severance pay and stock awards that will be fully vested with the deal’s completion.

Yahoo’s email and other digital services such as sports, finance and news will be run by Tim Armstrong, who has been in charge of AOL. Armstrong will now be CEO of a new Verizon subsidiary called Oath, which will consist of Yahoo and various AOL services.

“Now that the deal is closed, we are excited to set our focus on being the best company for consumer media, and the best partner to our advertising, content and publisher partners,” Armstrong said.

Verizon won’t be getting Yahoo’s prized stakes in two Asian internet companies, Alibaba Group and Yahoo Japan. Those will belong to a newly formed company called Altaba, which also will inherit Yahoo’s $8 billion in cash and any money that might have to be paid in various shareholder lawsuits filed against Yahoo leading up to the sale.

The suits include complaints tied to computer hacking attacks that stole personal information from more than 1 billion Yahoo user accounts in 2013 and 2014 but weren’t disclosed until last year. The fallout from the digital intrusions forced Yahoo to give Verizon a $350 million discount on the initial sale terms reached last July, causing the deal to be delayed by several months.

Altaba’s stock will begin trading next week under the ticker symbol “AABA.” Yahoo’s stock will trade through Friday.

Verizon is counting on the combination of Yahoo and AOL to build a strong third alternative in a rapidly growing digital advertising market that is currently dominated by Google and Facebook.
