NEW YORK ( TheStreet) -- Groupon is planning to launch a roadshow for its initial public offering next week, either Monday or Tuesday, three sources familiar with the situation told Reuters. The IPO is expected to value the Chicago-based deals company at more than $10 billion, likely in the range of $11 billion to $12 billion, two of the sources said. A spokesman for Groupon declined to comment for Reuters. Groupon filed for an IPO of up to $750 million in June, but has hit some roadblocks along the way to the offering. The company lost its chief operating officer in September after just five months on the job, and it has been criticized for altering its accounting metrics to appeal to investors. -- Written by Joseph Woelfel >To contact the writer of this article, click here: Joseph Woelfel >To submit a news tip, send an email to: email@example.com.
