Winston Score History

The full picture

Silicon Laboratories designs small computer chips that help everyday devices connect wirelessly to the internet. These chips go into things like smart thermostats, door locks, light bulbs, and industrial sensors — the kinds of products that make up what people call the "Internet of Things" (IoT). The company focuses entirely on IoT after selling its infrastructure and automotive chip businesses in 2021.

Silicon Labs makes money by selling its chips to electronics manufacturers around the world, with most revenue coming from customers in Asia who build connected devices at scale. The company is headquartered in Austin, Texas, and generates roughly $200 million in annual revenue, competing against larger chipmakers like Nordic Semiconductor and Texas Instruments. Its main competitive strength is low-power wireless chip design, which is hard to replicate quickly. The biggest risk is that the IoT market has been slow to recover from a chip inventory glut, which has kept demand — and profits — under pressure.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
