Company Overview
Founded in 1997 by its longtime CEO Michael Hsing, Monolithic Power Systems (NASDAQ:MPWR) is an analog and mixed signal chipmaker that specializes in power management chips meant to minimize total energy consumption.
Analog Semiconductors
Demand for analog chips is generally linked to the overall level of economic growth, as analog chips serve as the building blocks of most electronic goods and equipment. Unlike digital chip designers, analog chip makers tend to produce the majority of their own chips, as analog chip production does not require expensive leading edge nodes. Less dependent on major secular growth drivers, analog product cycles are much longer, often 5-7 years.
Sales Growth
A company’s long-term performance can indicate its business quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Over the last five years, Monolithic Power Systems grew its sales at an incredible 27.1% compounded annual growth rate. This is a great starting point for our analysis because it shows Monolithic Power Systems’s offerings resonate with customers. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions (which can sometimes offer opportune times to buy).
We at StockStory place the most emphasis on long-term growth, but within semiconductors, a half-decade historical view may miss new demand cycles or industry trends like AI. Monolithic Power Systems’s annualized revenue growth of 10.5% over the last two years is below its five-year trend, but we still think the results were good and suggest demand was strong. 
This quarter, Monolithic Power Systems reported wonderful year-on-year revenue growth of 30.6%, and its $620.1 million of revenue exceeded Wall Street’s estimates by 3.3%. Management is currently guiding for a 34.4% year-on-year increase next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 24% over the next 12 months, an improvement versus the last two years. This projection is commendable and indicates the market believes its newer products and services will spur faster growth.

Product Demand & Outstanding Inventory
Days Inventory Outstanding (DIO) is an important metric for chipmakers, as it reflects a business’ capital intensity and the cyclical nature of semiconductor supply and demand. In a tight supply environment, inventories tend to be stable, allowing chipmakers to exert pricing power. Steadily increasing DIO can be a warning sign that demand is weak, and if inventories continue to rise, the company may have to downsize production.
This quarter, Monolithic Power Systems’s DIO came in at 140, which is 24 days below its five-year average. At the moment, these numbers show no indication of an excessive inventory buildup.
Key Takeaways from Monolithic Power Systems’s Q3 Results
