Chinese e-commerce giant Alibaba Group Holding Ltd will hold the kickoff meeting for its planned U.S. initial public offering on March 25, setting in motion the most high-profile listing since Facebook Incs offering nearly two years ago, sources familiar with the plans said on Tuesday. The company, whose platforms handle more goods than EBay Inc and Amazon.com Inc combined, will meet with the six main banks arranging the deal, as well as lawyers and other professionals working on the IPO. In the meeting in Hong Kong, Alibaba will discuss their roles and outline plans for the listing, added the sources, who were not authorized to discuss the matter publicly. It is in discussions with Citigroup, Credit Suisse, Deutsche Bank, Goldman Sachs Group, J.P. Morgan, and Morgan Stanley for lead underwriting roles.
