Company Overview
Focusing on the silicon carbide and power semiconductor sectors, Amtech Systems (NASDAQ:ASYS) produces the machinery and related chemicals needed for manufacturing semiconductors.
Semiconductor Manufacturing
The semiconductor industry is driven by demand for advanced electronic products like smartphones, PCs, servers, and data storage. The need for technologies like artificial intelligence, 5G networks, and smart cars is also creating the next wave of growth for the industry. Keeping up with this dynamism requires new tools that can design, fabricate, and test chips at ever smaller sizes and more complex architectures, creating a dire need for semiconductor capital manufacturing equipment.
Sales Growth
A company’s long-term sales performance signals its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Unfortunately, Amtech’s 4.1% annualized revenue growth over the last five years was sluggish. This was below our standard for the semiconductor sector and is a poor baseline 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.
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. Amtech’s recent history shows its demand slowed as its revenue was flat over the last two years. 
This quarter, Amtech’s revenue fell by 2.1% year on year to $24.39 million but beat Wall Street’s estimates by 4.9%. Company management is currently guiding for a 13.5% year-on-year decline in sales next quarter.
We also like to judge companies based on their projected revenue growth, but not enough Wall Street analysts cover the company for it to have reliable consensus estimates.
Here at StockStory, we certainly understand the potential of thematic investing. Diverse winners from Microsoft (MSFT) to Alphabet (GOOG), Coca-Cola (KO) to Monster Beverage (MNST) could all have been identified as promising growth stories with a megatrend driving the growth. So, in that spirit, we’ve identified a relatively under-the-radar profitable growth stock benefiting from the rise of AI, available to you FREE via this link.
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, Amtech’s DIO came in at 155, which is 2 days below its five-year average. At the moment, these numbers show no indication of an excessive inventory buildup.
Key Takeaways from Amtech’s Q4 Results
We were impressed by Amtech’s strong improvement in inventory levels. We were also glad its revenue outperformed Wall Street’s estimates. On the other hand, its revenue guidance for next quarter missed significantly. Although not a perfect quarter, we think this was a decent quarter especially considering the uneven results in the sector this quarter. The stock traded up 3.8% to $5.44 immediately after reporting.
Is Amtech an attractive investment opportunity right now? 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.
