"In 2018, we focused on building a foundation to scale the business over the long-term by driving sustainable product innovation, scaling our advertising platform, and hiring the leadership team that will help us achieve our future goals," said Evan Spiegel, CEO. "We ended the year with user engagement stabilizing and have started rolling out the new version of our Android application to a small percentage of our community," he added. A large portion of Snap's issues stem from its Android issue. A bug on the Snap App on Android devices has caused massive issues for the company, and subsequently the stock. 

New advertising technology was also a part of Snap's better revenue picture. "Collection Ads, which enable a business to showcase four products in a single Snap, drove over twice the return on ad spend versus our comparable formats in Q4 2018," the company said in its earnings release. Higher return on ad spend usually enables a platform to charge higher ad prices. 

Management guided for first quarter 2019 revenue of between $285 million and $310 million. Wall Street is expecting revenue of $299 million.
