Yahoo! President and CEO Marissa Mayer

Yahoo CEO Marissa Mayer, once tasked with turning the struggling company around, is set to exit the company's board when its sale to Verizon closes, a company SEC filing said today.

The exit of Mayer, along with Yahoo co-founder David Filo and four other board members, will reduce the size of the company's board to five members. Upon closing the deal, Yahoo will take on a new name too: Altaba Inc.

Hired in July 2012 to help fix the flailing company, Mayer initially appeared to bring new life to Yahoo with shiny acquisitions, like the $1.1 billion purchase of Tumblr, that got the media and tech world buzzing. But ultimately, Mayer didn't steer Yahoo in a new direction. She'll hand over Yahoo to Verizon in essentially the same shape as she found it: a middling content company that tries to do a lot but excels at little.

As former Arizona Cardinals coach Dennis Green would put it:

Yahoo's final days as an independent company are mired in embarrassment, specifically recently revelations of a massive cyber attack that compromised over 1 billion users accounts. Verizon is demanding new terms following the damaging news.
