Roku plans to be a billion-dollar company in 2019, the company said on Thursday as part of its announcement of strong earnings. The company beat analyst estimates and reported strong growth in active users and streaming hours with earnings of $0.05 per share, compared with the $0.03 analysts had estimated, and revenues of $276 million, compared with the expected $262 million. Roku also reported 40 percent year-over-year active user growth, with 27.1 million active users by year-end, and a 69 percent year-over-year increase in streaming hours, which reached 7.3 billion. The company said it plans this year to invest in international expansion, its ad-supported service The Roku Channel, advertising, and its Roku TV platform. While cord cutting is driving some of Roku’s growth, only around half of Roku’s customers fit this description, CEO Anthony Wood pointed out.
