Compaq yesterday warned that revenue will fall short some US$1 billion for the quarter and that the company expects to post a loss of five to seven cents per share. Analysts had been expecting a profit of about five cents per share. Meanwhile, HP, which is acquiring Compaq, warned yesterday that it may cut more jobs this year, after already cutting nearly 7,000 positions. When the merger between the two companies is complete, another 15,000 jobs or so are expected to be cut as well.
