"I couldn't be prouder of the team that we have and what we've been able to achieve," she told CNBC's "Squawk on the Street."
"I love Yahoo, and I want to see Yahoo into the next chapter," she told CNBC's "Squawk on the Street."
She said AOL CEO Tim Armstrong "and I are old friends and colleagues and I very much respect him and am looking forward to working with him again."
Verizon purchased AOL's internet business last year for $4.4 billion. Armstrong will lead Yahoo's integration with AOL and Verizon.
Marni Walden, Verizon president of product innovation and new businesses, told CNBC's "Squawk Box" earlier Monday that Verizon had not yet made a decision about what role if any Mayer would have after the deal closes.
Mayer said her two immediate priorities are seeing the Yahoo sale through to its anticipated close in the first quarter of 2017 and managing the value of its remaining Asian assets.
After those issues are resolved, she said she is "very open-minded."
Verizon on Monday announced plans to acquire Yahoo for $4.8 billion in cash, ending months of uncertainty after Mayer's battered internet giant company said it would review strategic alternatives.
Mayer defended the company's achievements during her four years at the helm of the one-time internet titan, saying she did not view the sale of its operating business to Verizon as a failure.
"I think that overall when you look at what the company has achieved over its history and where we are today, I couldn't be prouder of the team that we have and what we've been able to achieve," she said.
When finalized, the deal would mark the end of Yahoo as an operating company, leaving it only as the owner of a 35.5 percent stake in Yahoo Japan, as well as its 15 percent interest in Chinese e-commerce company Alibaba . Yahoo will also retain its cash, convertible notes, certain minority investments, and a noncore portfolio of patents called Excalibur.
In December, Yahoo scrapped plans to spin off its Alibaba stake after investors worried about whether that transaction could have been carried out on a tax-free basis. It instead decided to explore a sale of its core assets, spurred on by activist hedge fund Starboard Value.
Five bidders submitted offers in the final round, CNBC reported last week.
Also last week, Yahoo reported quarterly earnings that slightly missed analysts' expectations, and revenue that beat projections — in part due to what Mayer called "disciplined expense management."
