The following will be posted on “Jeff’s Journal” in the Continental Airlines intranet web site on September 20, 2010:
New United Stock Will Trade on NYSE
Today, we announced management’s decision on a stock exchange and ticker symbol for the new United, which the board of directors of UAL Corporation will be asked to approve later this week. On the day of the legal closing of the merger, CO and United Airlines will both be subsidiaries of UAL Corporation, (which will be renamed United Continental Holdings, Inc.), and the stockholders will own shares in that holding company. The holding company will list its common stock on the New York Stock Exchange (NYSE) and is expected to open trading under the new ticker symbol UAL on Friday, Oct. 1, 2010. The NYSE is home to many of the world’s most well-established and high-quality companies, and we believe it provides the ideal trading platform as we work together to build the world’s leading airline.
