What happened

Shares of Dropbox (DBX 0.43%) have skyrocketed today, up by 21% as of 12:45 p.m. EST, after the company reported fourth-quarter earnings. The results beat expectations and the cloud storage pioneer announced a share repurchase plan.

So what

"Our strong Q4 marked the end of an exciting year for Dropbox as we launched our vision for the smart workspace," CEO Drew Houston said in a statement. "We closed the year with more than $1.6 billion in revenue, over 450,000 Dropbox business teams, and millions of people using our new foreground app that keeps Dropbox at the center of our users' workflows."

Now what

The tech company's board of directors has authorized a new $600 million share repurchase program. Investors were also excited that Dropbox is starting to shift its attention from growth toward profitability. On the conference call with analysts, management issued guidance that calls for revenue of $452 million to $454 million, which is comfortably above the $448 million in sales that the market was expecting.

CFO Ajay Vashee said the company is now focusing on delivering shareholder value and is raising its long-term operating margin target to a range of 28% to 30%, significantly higher than the previous target range of 20% to 22%. Dropbox expects to hit that goal by 2024. "To get there, we'll drive more efficiency and higher levels of productivity across each of our operating expense categories," Vashee said.
