“Amkor delivered a strong quarter, with record revenue in Computing and Automotive & Industrial end markets and continued margin expansion, despite expected weakness in Communications,” said Kevin Engel, Amkor’s president and chief executive officer. “We are executing on our strategy, advancing key customer programs and benefiting from expanding customer commitments that improve visibility and support disciplined investment to meet future demand.”
Revenue growth
A company’s top-line performance can indicate its business quality. Rapid growth can signal it’s benefiting from an innovative new product or burgeoning market trend. Amkor’s annualized revenue growth rate of 7.6% over the last two years was mediocre for a semiconductor business. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions.
This quarter, Amkor’s $1.99 billion of revenue was flat year on year, falling short of Wall Street’s consensus estimates. Company management is currently guiding for a 3.3% year-on-year increase in revenue next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 11% over the next 12 months, according to S&P. While this projection implies its newer products and services will spur better top-line performance, it is still below average for the sector.
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 34, which is 3 days above its five-year average, suggesting that the company’s inventory has grown to higher levels than in the past.
Key takeaways from Amkor’s Q3 results
Amkor’s softer quarter offered few positives, with revenue slightly below Wall Street’s consensus estimates and next-quarter revenue guidance also missing expectations. Shares nevertheless surged 6.4% to $39.20 immediately after the results.
