Investors are still apparently eager for more as the company continues to pivot toward a services-based model from its current focus making boxes for streaming television—a focus that, so far, has been quite successful. Despite competition from industry behemoths like Amazon and Google, Roku enjoys a dominant 37% share of the US streaming device market, according to Parks Associates, up from 30% last year.

The result has been some impressive financial growth metrics. For the six months ending June 30, revenue increased 23% YoY to nearly $200 million. Gross profit margin increased to 38% from 31%, helping the operating loss shrink to $21.2 million compared to $32.6 million in the year-ago period.
