Roku's Q3 revenue increased 12% to $761 million and beat expectations. However, the company slipped into a loss of $0.88 from EPS of $0.48 in the prior-year quarter due to higher operating expenses. The company expects Q4 revenue of about $800 million, reflecting a year-over-year decline of 7.5%. Roku expects the macro environment to further impact consumer discretionary spending and advertising budgets.
