Company Overview
With its technology found in common consumer electronics such as TVs and smartphones, Magnachip Semiconductor (NYSE:MX) is a provider of analog and mixed-signal semiconductors.
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
Reviewing a company’s long-term sales performance reveals insights into its quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Magnachip’s demand was weak over the last five years as its sales fell at a 18.3% annual rate. This wasn’t a great result and is a sign of poor business quality. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions.

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. Magnachip’s annualized revenue declines of 17.2% over the last two years suggest its demand continued shrinking.
This quarter, Magnachip reported robust year-on-year revenue growth of 24%, and its $63.04 million of revenue topped Wall Street estimates by 2.4%. Company management is currently guiding for a 9.3% year-on-year decline in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 9.4% over the next 12 months, an improvement versus the last two years. This projection is above average for the sector and suggests its newer products and services will fuel better top-line performance.
Today’s young investors won’t have read the timeless lessons in Gorilla Game: Picking Winners In High Technology because it was written more than 20 years ago when Microsoft and Apple were first establishing their supremacy. But if we apply the same principles, then enterprise software stocks leveraging their own generative AI capabilities may well be the Gorillas of the future. So, in that spirit, we are excited to present our Special Free Report on a profitable, fast-growing enterprise software stock that is already riding the automation wave and looking to catch the generative AI next.
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, Magnachip’s DIO came in at 59, which is one day above its five-year average. At the moment, these numbers show no indication of an excessive inventory buildup.
