Shares of cloud storage company Dropbox (NASDAQ:DBX) soared on Friday, its first day of trading as a public company. The company priced its IPO at $21 per share, above an earlier estimate of $16 to $18 per share. The stock was up about 33.5% at 3:45 p.m. EDT.
It's been a long road for Dropbox, which was founded back in 2007. The decade-old company has amassed over 500 million registered users in that time, with most of them taking advantage of its free offering. About 11 million of those users pay Dropbox for beefier plans, which offer more storage space and a broader feature set.
Dropbox isn't profitable on a GAAP basis, but revenue is growing quickly, and free cash flow is squarely positive. In 2017, Dropbox generated $1.1 billion of revenue, up 31% compared to 2016. That came with a $112 million GAAP net loss, but free cash flow totaled $305 million.
One reason for Dropbox's impressive free cash flow is its successful shift away from third-party cloud infrastructure providers. The company completed its transition to its own infrastructure toward the end of 2016. This led to a gross margin of 66.7% in 2017, more than double its 32.5% gross margin in 2015.
Despite ongoing losses, Dropbox's growth coupled with clear steps aimed at improving profitability seem to have won investors over.
While Dropbox is enjoying some Wall Street love today, the company still has a tough fight ahead of it. Cloud storage is a competitive market, and Dropbox will need to go toe to toe with Microsoft, Alphabet, Amazon, Apple, Box, and plenty of other smaller players. The company doesn't appear to have any real competitive advantage, but many of its competitors certainly do.
This doesn't mean Dropbox can't be a solid investment in the long run. But a strong debut will need to be followed up with improving financial performance for the stock to be a long-term winner.
