Simplify's Take
What believers are saying
- Q2 2026 revenue rose 18% to $228 million, with gross margin near 62%.
- Signify's Philips Hue dual-protocol rollout expands Silicon Labs into Matter and Zigbee homes.
- Comminent shipped 500,000 Wi-SUN modules for India's smart grid, validating utility traction.
What critics are saying
- Texas Instruments signed a $7.5 billion deal on February 4, 2026; closing needs approvals.
- Integration into TI ends Silicon Labs autonomy and triggers engineering attrition before 2027.
- NXP, Nordic, and STMicroelectronics attack its wireless sockets, compressing pricing and roadmap leverage.
What makes Silicon Laboratories unique
- Silicon Labs dominates ultra-low-power wireless for battery-powered IoT devices.
- BG2B combines Bluetooth 6, Secure Vault High, and integrated CAN-FD.
- Philips Hue and Wi-SUN wins prove sticky design-ins across smart home and grids.

↑ 0%Silicon Labs reported second quarter 2026 revenue of $228 million, up 18% year-over-year. The wireless IoT company saw strong performance across segments, with Industrial Commercial revenue reaching $135 million (up 23%) and Home Life revenue hitting $93 million (up 12%). Medical achieved record revenue, surging 78% year-over-year. Gross margin reached nearly 62%. The company posted a GAAP diluted loss per share of $0.32, improving 52% from the prior year period. Non-GAAP diluted earnings per share was $0.71, up 545% year-over-year. Silicon Labs has suspended forward-looking guidance due to its pending acquisition by Texas Instruments. The Austin-based company noted accelerating bookings and declining inventory at distributors and end customers during the quarter.
Silicon Labs has announced the BG2B, its lowest-power Bluetooth Low Energy system-on-chip. The Austin-based company says the device combines Bluetooth 6 Channel Sounding technology with Secure Vault High security and integrated peripherals including CAN-FD and LED drivers. The BG2B delivers 14-15% lower active current consumption and 1.1 microamp sleep current compared to Silicon Labs' previous Bluetooth LE chip. The device is designed for applications including secure ranging, asset tracking, electronic shelf labels, smart home devices, and vehicle diagnostics. The chip integrates CAN-FD connectivity, eliminating the need for separate bridge devices in commercial vehicles and industrial equipment. It also includes integrated LED boost capabilities and dual 12-bit ADCs. BG2B is currently available through an early customer programme, with initial production hardware and modules planned for 2027.
Signify and Silicon Labs have announced a collaboration to bring concurrent multiprotocol communications to select Philips Hue smart bulbs, enabling support for both Zigbee and Matter over Thread simultaneously on a single device. The new Philips Hue bulbs leverage Silicon Labs' MG26 and SiMG301 wireless SoCs to deliver greater flexibility whilst maintaining advanced features like dynamic scenes, entertainment synchronisation and automation capabilities. The technology allows consumers to integrate bulbs into leading smart home ecosystems for everyday controls whilst accessing premium Hue-specific functionality. Select Philips Hue smart bulbs using the Silicon Labs technology are available now or being introduced across product lines. Whilst products currently require choosing Zigbee or Thread at commissioning, a software update enabling concurrent operation will launch later this year.
Comminent has shipped over 500,000 Wi-SUN-compliant communication modules powered by Silicon Labs' EFR32FG28 Wireless SoC to support India's smart grid infrastructure. The milestone reflects growing adoption of Wi-SUN technology in the country's Revamped Distribution Sector Scheme, one of the world's largest smart meter rollouts. The Bureau of Indian Standards has adopted the global Wi-SUN Field Area Network specification as the national standard for smart meter RF communication networks. Comminent's modules utilise Silicon Labs' dual-band SoC, which combines sub-GHz and Bluetooth LE connectivity with enterprise-grade security through Secure Vault technology. The deployment enables utilities to implement scalable, self-healing wireless mesh networks. Comminent is now expanding into global smart grid markets including the US and Japan.
Silicon Labs reported first quarter 2026 revenue of $214 million, up 20% year-over-year, with non-GAAP diluted earnings per share of $0.53. The wireless IoT company posted GAAP gross margin of 59.5% and a GAAP operating loss of $17 million. Industrial and commercial revenue reached $128 million, up 33% year-over-year, driven by electronic shelf labels and smart metering applications. Home and life revenue grew 5% to $86 million, with medical applications up 21%. The company reported accelerating bookings and declining inventory at distributors, with book-to-bill ratio at a multi-year high. Design wins exceeded internal targets and 2025's record pace. Silicon Labs has suspended forward-looking guidance due to its pending acquisition by Texas Instruments, which continues to advance.
