In case you were focused on the negative aspects of Marissa Mayer's leadership of Yahoo! Inc. (YHOO) , the former CEO laid out some of her accomplishments in a farewell blog post on Tuesday. Mayer's tenure at the company ended as the $4.48 billion sale of its operating business to Verizon Communications Inc.'s (VZ) officially closed.
Yahoo! became just one of three Internet companies with more than 1 billion monthly users, she blogged on Tumblr. The others are Facebook Inc. (FB) and Alphabet Inc.'s (GOOGL) Google. Mayer formerly worked for Google.
Sales for Yahoo!'s MaVeNS--or mobile, video, native advertising and social media businesses--grew from "essentially zero" in 2011, the year before she arrived, to more than $2 billion, she added. Mobile users surpassed 650 million people on her watch, she said.
Mayer took criticism for serial acquisitions of companies like Tumblr, for which Yahoo! paid $1.1 billion, and failing to turn around the operating business. However, she noted that the company gained $43 billion in value during her time, with its market cap rising from $18 billion to $51 billion and the company paying out $10 billion to shareholders.
The outgoing Yahoo! CEO did not mention that much of that value came from the ballooning value of Alibaba Group Holding Inc. (BABA) stock that Yahoo!'s former CEO and co-founder Jerry Yang bought. Before Alibaba's massive 2014 IPO, Yahoo! presented investors a means of investing in the Chinese e-commerce giant.
And while the value of Yahoo!'s stock and buybacks grew mightily, the price for the sale of the operating business actually dropped. Verizon initially agreed to pay $4.8 billion for the business last year, but reduced the price by $350 million after Yahoo! disclosed a pair of massive hacks.
Yahoo! and its brands are now part of Verizon's Oath business, which includes HuffPost, AOL.com, Tumblr, BUILD Studios and others.
Mayer was mum about her next step.
"Given the inherent changes to my role, I'll be leaving the company," Mayer wrote. "However, I want all of you to know that I'm brimming with nostalgia, gratitude, and optimism." While Mayer did not suggest what her next move might be, TheStreet.com recently wrote that venture capital or private equity could be an ideal spot for the former Yahoo! boss.
