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.

Sales 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. Magnachip’s demand was weak over the last five years as its sales fell at a 17.6% annual rate. This was below our standards and suggests it’s a low quality business. 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 11.5% over the last two years suggest its demand continued shrinking.

This quarter, Magnachip reported a rather uninspiring 8.9% year-on-year revenue decline to $44.72 million of revenue, in line with Wall Street’s estimates. Company management is currently guiding for a 11.6% year-on-year decline in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to decline by 10.9% over the next 12 months, similar to its two-year rate. This projection is underwhelming and implies its newer products and services will not catalyze better top-line performance yet.

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 84, which is 24 days above its five-year average, suggesting that the company’s inventory has grown to higher levels than we’ve seen in the past.

Key Takeaways from Magnachip’s Q1 Results

We were impressed by how significantly Magnachip blew past analysts’ EPS and EBITDA expectations this quarter. On the other hand, its revenue guidance for next quarter missed significantly and its inventory levels increased. Overall, this print was mixed but still had some key positives. The stock traded up 4.8% to $3.50 immediately after reporting.

So do we think Magnachip is an attractive buy at the current price? The latest quarter does matter, but not nearly as much as longer-term fundamentals and valuation, when deciding if the stock is a buy. We cover that in our actionable full research report which you can read here, it’s free.
