Examining a company’s long-term performance can provide clues about its quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Over the last five years, Kulicke and Soffa’s demand was weak and its revenue declined by 1.6% per year. 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. Kulicke and Soffa’s recent performance shows its demand remained suppressed as its revenue has declined by 3.4% annually over the last two years.

This quarter, Kulicke and Soffa reported robust year-on-year revenue growth of 20.2%, and its $199.6 million of revenue topped Wall Street estimates by 5%. Adding to the positive news, Kulicke and Soffa’s growth inflected positively this quarter, indicating that the recent cyclical downturn is likely in the rearview mirror. Company management is currently guiding for a 42% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 16.3% over the next 12 months, an improvement versus the last two years. This projection is noteworthy and indicates its newer products and services will fuel better top-line performance.

The 1999 book Gorilla Game predicted Microsoft and Apple would dominate tech before it happened. Its thesis? Identify the platform winners early. Today, enterprise software companies embedding generative AI are becoming the new gorillas. a profitable, fast-growing enterprise software stock that is already riding the automation wave and looking to catch the generative AI next.

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, Kulicke and Soffa’s DIO came in at 160, which is 6 days below its five-year average. These numbers show that despite the recent increase, there’s no indication of an excessive inventory buildup.

It was good to see Kulicke and Soffa beat analysts’ EPS expectations this quarter. We were also excited its adjusted operating income outperformed Wall Street’s estimates by a wide margin. On the other hand, its inventory levels increased. Zooming out, we think this quarter featured some important positives. The stock traded up 3.5% to $57.60 immediately after reporting.

Kulicke and Soffa may have had a good quarter, but does that mean you should invest right now?
