Company Overview
Founded by Caltech professor Carver Mead and one of his students Chris Diorio, Impinj (NASDAQ: PI) is a maker of radio-frequency identification (RFID) hardware and software.
Analog Semiconductors
Demand for analog chips is generally linked to the overall level of economic growth, as analog chips serve as the building blocks of most electronic goods and equipment. Unlike digital chip designers, analog chip makers tend to produce the majority of their own chips, as analog chip production does not require expensive leading edge nodes. Less dependent on major secular growth drivers, analog product cycles are much longer, often 5-7 years.
Sales Growth
Examining a companyโs long-term performance can provide clues about its business quality. Any business can put up a good quarter or two, but the best consistently grow over the long haul. Thankfully, Impinjโs 18.7% annualized revenue growth over the last five years was exceptional. This is a great starting point for our analysis because it shows Impinjโs 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 (which can sometimes offer opportune times to buy).
Long-term growth is the most important, but recency is neccessary for semiconductors because of Moore's Law, which suggests the pace of technological innovation is so high that yesterday's hit new product could be obsolete today. Impinjโs annualized revenue growth of 21.5% over the last two years is above its five-year trend, suggesting its demand was strong and recently accelerated.
This quarter, Impinj reported magnificent year-on-year revenue growth of 46.4%, and its $95.2 million of revenue beat Wall Streetโs estimates by 2.5%. Management is currently guiding for a 30.9% year-on-year increase next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 21.3% over the next 12 months, similar to its two-year rate. This projection is admirable and illustrates the market sees some success for its newer products and services.

Product Demand & Outstanding Inventory
Days Inventory Outstanding (DIO) is an important metric for chipmakers, as it reflects a businessโ 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, Impinjโs DIO came in at 169, which is 9 days above its five-year average, suggesting that the companyโs inventory has grown to higher levels than weโve seen in the past.
