Founded by billionaire Jack Ma, Alibaba is expected to file for an estimated $15 billion IPO in 2014, valuing the operator of retail, auction and content websites at more than $100 billion. The IPO is one of the most eagerly anticipated Internet debuts since Facebook Inc in 2012.
Alibaba has decided not to list its shares in Hong Kong, but has not yet committed to listing on any other exchange, including the New York Stock Exchange, CEO Jonathan Lu told Reuters last week.
Under the terms of an amended agreement that Yahoo announced alongside its quarterly results, the U.S. Internet company will sell up to 208 million of the 523.6 million Alibaba shares it owns, either directly to the Chinese company or through the IPO. That is down from a previously agreed maximum of 261.5 million.
After the IPO, Yahoo would have the right to sell its remaining Alibaba shares at its discretion, Yahoo said.
A spokesman for Alibaba said that the terms of the previous agreement, which permitted Yahoo to sell only after a one-year lock-up period following the IPO, would remain in force.
On Tuesday, Yahoo announced second-quarter results from Alibaba, in which it holds a 24 per cent stake, underscoring the Internet, retail and content company's rapid growth.
Alibaba's revenue grew 61 per cent to $1.74 billion in the April to June period, while net income jumped 159 per cent to $707 million. That pace is down from 71 per cent in the first quarter, but still exceeded BGC Partners analyst Colin Gillis' forecast for about 54 per cent.
