Silicon Laboratories (SLAB) FY2025 results: revenue $785 million, up 34.3% on the year

Silicon Laboratories designs wireless chips, software and development tools that device makers use to build connected products for the Internet of Things, in industrial, commercial, home and health applications. Its chips use standard CMOS, a widely available process technology, and they combine on a single chip, chipset or system-on-chip functions that competing products often spread across many discrete components. Its platform supports Bluetooth, sub-GHz proprietary technologies, Wi-SUN, Thread, Wi-Fi, Zigbee and Z-Wave. The filing states that its products have relatively long life cycles because of the time customers need to design them in.

Pending merger

On February 4, 2026 it agreed to be acquired by Texas Instruments for cash, with the company surviving as a wholly owned subsidiary of Texas Instruments. At the time of the filing the merger still needed stockholder approval and regulatory approvals, and the company expected it to close in the first half of 2027.

Products

Its main products are wireless microcontrollers and wireless systems-on-chip under families that include EFM32 and EFM8, ranging from 8-bit microcontrollers to 32-bit devices built on ARM Cortex-M cores, along with modules. Its Series 2 portfolio, introduced in 2019, added a focus on updatable device security, and its Series 3 portfolio released its first product in 2025 on the 22 nm process node. Its Simplicity Studio software gives developers access to design tools, documentation, software and support.

Markets

It groups its products into two markets. Industrial and Commercial covers uses such as industrial automation, smart metering, smart street lighting, renewable energy, electric vehicle supply equipment, smart buildings, access controls, asset tracking and electronic shelf labels. Home and Life covers smart home devices such as cameras, locks, gateways, residential lighting, HVAC and appliances, with support for Matter and Amazon Sidewalk, and connected health devices such as continuous glucose monitors, insulin pumps and fitness wearables.

Customers and sales

It sells through its direct sales force and through independent sales representatives and distributors, and customers buy on individual purchase orders rather than long-term agreements. It counts as its customer the end customer, whether that customer buys directly, through a distributor or through a contract manufacturer, and its distributors include Arrow Electronics and Edom Technology. It has sales offices in Asia, the Americas and Europe. The time to win a design into a customer's product can range from about three months to two years.

Manufacturing

It is a fabless company that designs its chips in-house and partners mainly with Taiwan Semiconductor Manufacturing Co. and Semiconductor Manufacturing International Corporation to make most of its wafers. The wafers are shipped to third-party assembly subcontractors, and in fiscal 2025 most of its units shipped were tested by offshore third-party test subcontractors.

Competition

The filing names as competitors Espressif, Infineon, MediaTek, Microchip, Nordic Semiconductor, NXP, Qualcomm, Renesas, STMicroelectronics, Synaptics, Telink and Texas Instruments. It lists product size, level of integration, capabilities, reliability, price, performance, power requirement, customer support, reputation, speed of new product introduction, intellectual property and software as the main competitive factors.

People

As of January 3, 2026 it employed 1,930 people, of whom 72% were in engineering roles, with sites and employees in more than a dozen countries.
