Company Overview
Formed by the 1997 merger of the two leading semiconductor yield management companies, KLA Corporation (NASDAQ: KLAC) is the leading supplier of equipment used to measure and inspect semiconductor chips.
Revenue Growth
A company’s long-term sales performance is one signal of its overall quality. Any business can have short-term success, but a top-tier one grows for years. Luckily, KLA Corporation’s sales grew at an impressive 15.2% compounded annual growth rate over the last five years. Its growth surpassed the average semiconductor company and shows its offerings resonate with customers, a great starting point 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 (which can sometimes offer opportune times to buy).
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. KLA Corporation’s annualized revenue growth of 16.8% over the last two years is above its five-year trend, suggesting its demand was strong and recently accelerated. 
This quarter, KLA Corporation reported year-on-year revenue growth of 11.5%, and its $3.42 billion of revenue exceeded Wall Street’s estimates by 1.2%. Beyond the beat, this marks 8 straight quarters of growth, showing that the current upcycle has had a good run - a typical upcycle usually lasts 8-10 quarters. Company management is currently guiding for a 12.6% year-on-year increase in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 20.7% over the next 12 months, an improvement versus the last two years. This projection is above average for the sector and suggests its newer products and services will fuel better top-line performance.

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, KLA Corporation’s DIO came in at 236, 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.
