Company Overview
Operating through a largely Asian facility footprint, Amkor Technologies (NASDAQ: AMKR) provides outsourced packaging and testing for semiconductors.
Revenue Growth
A company’s long-term sales performance can indicate its overall quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Luckily, Amkor’s sales grew at a decent 6.4% compounded annual growth rate over the last five years. Its growth was slightly above the average semiconductor company and shows its offerings resonate with customers. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions.
Long-term growth is the most important, but short-term results matter for semiconductors because the rapid pace of technological innovation (Moore’s Law) could make yesterday’s hit product obsolete today. Amkor’s annualized revenue growth of 7.9% over the last two years is above its five-year trend, which is encouraging. 
This quarter, Amkor reported robust year-on-year revenue growth of 25.6%, and its $1.90 billion of revenue topped Wall Street estimates by 4.5%. Beyond the beat, this marks 5 straight quarters of growth, implying that Amkor is in the middle of its cycle - a typical upcycle generally lasts 8-10 quarters. Company management is currently guiding for flat sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 7.5% over the next 12 months, similar to its two-year rate. This projection is underwhelming and suggests its newer products and services will not lead to better top-line performance yet.

Product Demand & Outstanding Inventory
Days Inventory Outstanding (DIO) is an important metric for chipmakers, as it reflects a business’s 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, Amkor’s DIO came in at 32, which is 2 more days than its five-year average, suggesting that the company’s inventory levels have grown slightly above the long-term average.
Key Takeaways from Amkor’s Q2 Results
It was good to see Amkor beat analysts’ EPS expectations this quarter. We were also excited its operating income outperformed Wall Street’s estimates by a wide margin. On the other hand, its revenue guidance for next quarter missed and its inventory levels slightly increased. Overall, we think this was still a decent quarter with some key metrics above expectations. The stock traded up 5.9% to $64.40 immediately following the results.
Indeed, Amkor had a rock-solid quarterly earnings result, but is this stock a good investment here? The latest quarter does matter, but not nearly as much as longer-term fundamentals and valuation, when deciding if the stock is a buy.
