Dropbox Inc. aims to raise as much as US$648 million in its U.S. initial public offering.

The company is marketing 36 million shares range from US$16 to US$18 apiece, according to a filing with the U.S. Securities and Exchange Commission Monday.

Dropbox, which was valued at US$10 billion in its 2014 funding round, would be one of the biggest U.S. enterprise technology companies to list domestically in several years. First Data Corp. went public at a market value of about US$14 billion in 2015 -- the biggest such IPO in the past five years.

The San Francisco-based file-sharing company has touted its business as a path to unleashing creative energy and inspired work. Dropbox says it has more than 500 million registered users, with 11 million of those paying for added features.

While the company is inching closer to profitability, Dropbox outlined in its deal prospectus its focus to get more of those users to pay up. Investors are sure to have questions for the file-sharing technology leader as it embarks on its marketing roadshow.

The company’s revenue increased more 30 per cent last year to US$1.1 billion from US$845 million in 2016. In the same period, the company’s net losses shrank to US$112 million from US$210 million.

Goldman Sachs Group Inc., JPMorgan Chase & Co., Deutsche Bank AG and Allen & Co. are leading the offering. The company plans to list on Nasdaq Global Select Market under the symbol DBX.
