The file-sharing company noted that it completed the acquisition of e-signature and document workflow platform HelloSign for $230 million during the quarter. The company said it would provide forward-looking guidance during its conference call at 5 PM ET. 

"We kicked off 2019 with a strong Q1, driven by continued paying user growth and ARPU expansion," said Dropbox Co-founder and Chief Executive Officer Drew Houston. "Our 22% top-line growth and robust operating margins reflect our efficient go-to-market strategy and operational discipline. We've reached a scale few SaaS companies have achieved and continue to ship product experiences that put Dropbox at the center of our users' workflows. We also closed our first acquisition as a public company with HelloSign, and I'm excited about our future together."
