Revenue Growth

Examining a company’s long-term performance can provide clues about its quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Thankfully, Monolithic Power Systems’s 29.9% annualized revenue growth over the last five years was incredible. Its growth surpassed the average semiconductor company and shows its offerings resonate with customers, a great starting point for our analysis. 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 17.3% over the last two years is below its five-year trend, but we still think the results suggest healthy demand.

This quarter, Monolithic Power Systems reported wonderful year-on-year revenue growth of 31%, and its $664.6 million of revenue exceeded Wall Street’s estimates by 1.9%. Beyond the beat, this marks 6 straight quarters of growth, showing that the current upcycle has had a good run - a typical upcycle usually lasts 8-10 quarters. Company management is currently guiding for a 16.1% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 10.1% over the next 12 months, a deceleration versus the last two years. Despite the slowdown, this projection is commendable and implies the market sees success for its products and services.

Unless you’ve been living under a rock, it should be obvious by now that generative AI is going to have a huge impact on how large corporations do business. While Nvidia and AMD are trading close to all-time highs, we prefer a lesser-known (but still profitable) stock benefiting from the rise of AI.

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 150, which is 12 days below its five-year average. These numbers show that despite the recent increase, there’s no indication of an excessive inventory buildup.
