Business Outlook

The company expects revenue in the fourth quarter to be in the range of $156 million to $161 million. Fourth quarter diluted earnings per share are expected to be between $0.05 and $0.11 on a GAAP basis and between $0.45 and $0.51 on a non-GAAP basis.

“Strong top line performance combined with favorable opex drove a solid beat in third quarter EPS,” said Tyson Tuttle, CEO of Silicon Labs. “We delivered another record revenue quarter in Infrastructure, with continued strength in IoT and Broadcast automotive, and a less than expected decline in Broadcast consumer.

“Despite the challenging macro environment, we are confident in our strategy and proud of our accomplishments. We have a rich product pipeline and see strong demand for our silicon and software. We are engaging with top industry leaders who are rapidly adopting our IoT solutions and propelling our design win activity to record levels. We are executing on our vision and strategy and excited about what lies ahead.”
