Now what

In a statement, CEO Mike Bell said that Silver Spring is in the process of "right-sizing our expense structure to support our goal of profitable growth as we extend Silver Spring's technology to the broader Internet of Important Things markets." The company slightly lowered its outlook for 2017. Silver Spring now expects full-year 2017 billings to be "in the range of flat to up approximately 5% versus last year."
