Silicon Laboratories Inc. (SLAB) delivered robust financial results for the fourth quarter and full year of 2025, underscoring its leadership in semiconductor solutions for smart devices and industrial IoT applications. The company reported Q4 2025 revenue of $248 million, a 12% increase compared to the same period in 2024, driven by strong demand for its wireless connectivity chips and energy-efficient microcontrollers. For the full fiscal year 2025, revenue totaled $943 million, marking a 10% year-over-year rise. Non-GAAP earnings per share reached $1.16 in Q4 and $4.23 for the year, surpassing the consensus estimates of $1.10 and $4.15, respectively. The company’s gross margin for the quarter was 68.4%, reflecting disciplined cost management and favorable product mix.
