RokuAfter the announcement of third quarter earnings, which were below revenue expectations, shares fell in trading after hours on Wednesday

Roku reported earnings of 48 cents per share in the third quarter on $680 million revenue. Analysts expected earnings to be 6 cents for revenue of $683.4 millions. From a year ago, revenue increased by 51%.

To 56.4 millions, active accounts on this platform increased by 23% in the past year. There was also an increase by 1.3 million accounts in the second quarter. But, growth has slowed.

According to the shareholder letter, the company explained that the slowdown in sales was caused by “global supply disruptions that have adversely affected the U.S. TV industry.” According to the company, TV sales also dropped below levels of 2019 prior to the pandemic. Original equipment manufacturers were also affected by limited inventory.

CFO Steve Louden said that “the pandemic continues disrupting global supply chains.” He spoke to CNBC in an interview following the report. You’re experiencing increased component prices, inventory availability problems, and delays in supply chain logistics for the television industry.
