What happened with Silicon Labs this quarter?

  • On an adjusted (non-GAAP) basis, which excludes items such as stock-based compensation and acquisition expenses, net income arrived at $39.2 million, or $0.90 per share.
  • These results compared favorably with Silicon Labs' latest guidance, which called for revenue of $193 million to $199 million, GAAP earnings per share of between $0.35 and $0.41, and adjusted earnings per share of between $0.78 and $0.84.
  • Internet of Things revenue, which exceeded 50% of total sales for the first time last quarter, grew 23% year over year to $100 million, setting another company record.
  • Infrastructure revenue climbed 1% year over year to $39 million.
  • Broadcast revenue rose increased 6% year over year to $43 million.
  • Access revenue fell 3% year over year to $17 million.
  • Notable new product launches and introductions this quarter included:
    • The Si72xx magnetic sensor portfolio, offering flexible Hall-effect magnetic sensors.
    • The Si5381/82/86 wireless clock series, delivering advanced timing solutions coming 4G/LTE and Ethernet clocking in a single integrated circuit.
    • New Global Eagle and Dual Eagle AM/FM receivers and digital radio tuners, designed for automakers' and Tier 1 suppliers' auto infotainment needs.
    • The introduction of a new USB Type-C reference design to simplify development of rechargeable battery packs for portable devices.

What management had to say

"We are very pleased with our third-quarter results, achieving record revenue in IoT and infrastructure, and in total," said Silicon Labs CEO Tyson Tuttle. "Our portfolio is well positioned in high-quality growth markets, including IoT, infrastructure, green energy, and data communications, where we generate more than 70% of our total revenue, offering a long runway for growth and share gains."

Looking forward

For the fourth quarter of 2017, Silicon Labs expects revenue of $195 million to $201 million, GAAP earnings per diluted share of between $0.40 and $0.46, and adjusted earnings per share of between $0.83 and $0.89. For perspective -- and though we typically don't pay close attention to Wall Street's demands -- consensus estimates were modeling adjusted earnings near the low end of that range on revenue of $197.6 million.

For Silicon Labs, this was yet another straightforward case of under-promising, over-delivering, and offering investors an optimistic view of what's to come.
