“Monolithic Power Systems, Inc. (NASDAQ:MPWR) designs chips that deliver precise, safe, and efficient power to processors, memory, and sensors in electronic systems. With deep system-level expertise and highly integrated solutions, MPS has established a strong leadership position in power management. Shares rose 21.0% during the quarter following continued robust quarterly results, closing 2025 with full year revenues of $2.8 billion, up 26% year on-year, while guiding Q1 2026 meaningfully above expectations with revenues of $780 million (at the mid-point) compared to consensus estimates of $738 million. The company is poised to benefit from two major secular trends: AI-driven data center redesigns and automotive electrification. AI is fueling exponential growth in data center power needs, forcing a fundamental rethink in how power is distributed. While server shipments are experiencing unprecedented growth, power content per system is also rising, creating a durable multi-year tailwind. At the same time, vehicles are shifting to centralized computing and higher-voltage architectures, significantly increasing the need for advanced power management content per vehicle. MPS’ leadership positions it to directly benefit from both the AI infrastructure buildout and long term automotive electrification trend.”
