Monolithic Power Systems

What Monolithic Power Systems does

Monolithic Power Systems (NASDAQ: MPWR) is a fabless semiconductor company founded in 1997 and headquartered in the United States, specializing in high-performance power management integrated circuits (ICs), power modules, and isolation products. The company designs and markets products based on proprietary Bipolar-CMOS-DMOS (BCD) process technology, monolithic DrMOS (Intelli-Phase), capacitive digital isolation up to 5kVRMS, and emerging GaN/SiC high-frequency gate drivers. Its portfolio spans switching converters and controllers, multi-phase power delivery solutions for AI accelerators, fully integrated power modules (Intelli-Module), battery management ICs, motor drivers, sensors, PoE solutions, and Class-D audio amplifiers (including technology acquired from Axign in 2024). All manufacturing is performed through third-party foundries while MPS retains design and customer support responsibility.

MPS serves enterprise customers across five primary segments: Enterprise Data Center and AI Infrastructure (now nearly 80% of revenue growth at 97.7% YoY), Automotive (AEC-Q100 qualified, 30%+ YoY growth), Consumer Electronics, Industrial, and Communications. Revenue from the China region accounts for 55.3% of total sales, with additional operations in Taiwan, South Korea, Europe, and North America. The company's go-to-market combines direct enterprise sales with field application engineers, a global distribution network, and an extensive reference design partner ecosystem with AMD/Xilinx, Intel/Altera, Qualcomm, Lattice, Micron, Semidrive, Achronix, and Cypress Semiconductor.

The business model is hardware sales of proprietary semiconductor products through quote-based B2B pricing with volume discounts and long-term supply agreements. Q1 2026 record revenue of $804.2 million (up 26.1% YoY) and Q2 guidance of $890-910 million reflect strong AI infrastructure demand. Gross margin is maintained at approximately 55.5% with operating margin expansion to 30% from 26.5% YoY. The company was added to the NASDAQ-100 Index in December 2025 and increased its quarterly dividend by 28% to $2.00 per share in April 2026, returning capital to shareholders while sustaining capital expenditure for capacity expansion.
