Privately-held Alibaba is widely expected to have a share sale as early as this year.
The company is the biggest player in China's fast-growing e-commerce market.
The company operates online platforms Alibaba.com, Taobao and Tmall, which connect small sellers and major companies with consumers and business partners.
Alibaba's revenues come from advertisements on the websites and customer fees.
Yahoo has a 24% stake in Alibaba, after the e-commerce company bought back some of its shares last year. Included in the terms of that buyback were incentives for Alibaba to list its shares before the end of 2015.
Alibaba has not publicly announced the details or timeline of the share sale. However, industry observers expect it could be as early as this year.
The strong earnings are part of wider growth in China's ecommerce industry, which is set to surpass the US in the coming years.
