The company reported 90% of interim revenue outside the United States and estimated that China-based end customers accounted for 19% of revenue, versus 31% by shipped-to location.[25]+2

Austin, Texas is the corporate headquarters and includes engineering, sales and marketing, administrative, and test operations. The company also leases smaller facilities in the United States, Canada, China, Denmark, Finland, France, Germany, Hungary, India, Italy, Japan, Norway, Singapore, South Korea, Taiwan, and the United Kingdom; these support engineering, sales and marketing, administration, and manufacturing support. Singapore is described as the headquarters for non-U.S. operations.[28][29]

Silicon Laboratories describes its manufacturing model as fabless. Most of its foundries and several assembly and test subcontractor sites are in Taiwan, while most of its other foundry, assembly, and test subcontractors are in the Pacific Rim. The company reported 1,930 employees as of January 3, 2026; the cited filing does not provide a geographic employee breakdown.[30][31] [23]+15

Business segments

Silicon Laboratories reports one operating and reportable segment, “mixed-signal analog intensive products,” rather than separate reportable business segments. Its latest annual filing, for FY2025, and its Q2 2026 filing retain this single-segment presentation.[21][32]

The company also presents revenue by two product-market categories, which are not identified as reportable segments. In FY2025, Industrial & Commercial revenue was approximately $445 million, or 56.7% of total revenue of $785 million; this category serves markets including industrial automation and control, smart metering and lighting, commercial buildings, asset tracking, and smart retail.[33]+3 Home & Life revenue was approximately $340 million, or 43.3% of total revenue, covering smart-home connectivity and security, appliances, and connected-health applications.[36]+3 Percentages are calculated from the reported, rounded revenue amounts.

Company history

Silicon Laboratories was founded in 1996 by Nav Sooch, Dave Welland and Jeff Scott. Its early product work included modem-interface and RF technologies, and the company completed its Nasdaq IPO in March 2000.[37][38]

From 2012 to 2020, a series of acquisitions expanded the company’s low-power wireless, microcontroller and IoT connectivity capabilities. These included Ember in 2012, Energy Micro in 2013, Bluegiga in 2015, Zentri in 2017, and Redpine Signals’ connectivity business in 2020.[39]+4

In 2021, Silicon Labs agreed to sell its Infrastructure & Automotive business to Skyworks; the sale closed that July, marking a strategic refocus on IoT wireless connectivity. Matt Johnson succeeded Tyson Tuttle as CEO at the beginning of 2022.[44]+2 In February 2026, Texas Instruments announced an agreement to acquire Silicon Labs; the announcement described a proposed transaction.[47] [37]+10
