Roku shares fell more than 8% in after-hours trading Wednesday after reporting second-quarter earnings that beat expectations but showed a slowdown in streaming TV viewing and tight hardware margins.

Here’s how the company did compared to Refinitiv consensus estimates:

EPS: $0.52 per share vs. estimate of $0.13 per share
Revenue: $645 million vs. estimate of $618 million

The company said streaming hours decreased by 1 billion hours from the first quarter of 2021. The company cited consumers seeking more out-of-home entertainment activities like dining and travel in the second quarter because of pent-up demand and the loosening of Covid-19 restrictions.

In its shareholder letter, it also said “tight component supply conditions and shipping constraints” continued increasing costs faster than expected.

“In Q2, we insulated consumers from increased costs for Roku players, which resulted in Player gross margin turning negative in the quarter,” the letter says.

The company’s total net revenue grew 81% year-over-year in the quarter to $645 million. Meanwhile, it said its platform revenue exceeded half a billion dollars in the quarter for the first time in the segment’s history, reaching $532 million, driven by content distribution and advertising.
