Business Highlights

  • Broadcast outperformed expectations in the fourth quarter with revenue of $49.6 million.
  • Access grew slightly in the fourth quarter, exceeding expectations, with revenue of $24.3 million.
  • During the fourth quarter, the company announced several important mixed-signal products for Internet of Things applications, including the energy-friendly EFM32™ Zero Gecko MCU family, the ultra-low-power Si106x/8x wireless MCU family, and the next-generation Si701x/2x relative humidity and temperature sensor family.

“We are very pleased with our performance in the fourth quarter, as our microcontroller and wireless products delivered another record revenue quarter, and we experienced better than expected revenue from Broadcast and Access products,” said Tyson Tuttle, CEO of Silicon Labs. “Revenue for 2013 was a record for the company, and we believe we are entering 2014 well positioned in growth markets such as the Internet of Things, smart energy and Internet infrastructure.”

Business Outlook

The company expects revenue in the first quarter to be in the range of $142 million to $146 million. The company expects first quarter earnings per share to be between $0.14 and $0.18 on a GAAP basis and between $0.40 and $0.44 on a non-GAAP basis.
