Silicon Laboratories Inc.
A fabless semiconductor company that designs chips for the Internet of Things, Silicon Labs makes low-power microcontrollers and wireless system-on-chips (like the EFR32 series) that let smart-home devices, industrial gear, and wearables talk over Bluetooth, Zigbee, and Wi-Fi. Founded in Austin, Texas in 1996 by three engineers who flipped a coin to decide whether to start the company, it first made its mark with a silicon replacement for the bulky transformers every telephone modem once required.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last year: -17.4K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
