Twitter lost almost as much money in the July-to-September quarter as it did in the first six months of this year, according to a regulatory disclosure made by the company on Tuesday. Twitter, which is preparing for an imminent initial public offering of its stock to investors, submitted an updated S1 filing to the U.S. Securities and Exchange Commission that contained financial results for the first nine months of its current financial year. Its previous filing had only contained figures for the first six months, from February until the end of June.
