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

A company’s long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Over the last five years, Impinj grew its sales at an excellent 16.8% compounded annual growth rate. Its growth beat the average semiconductor company and shows its offerings resonate with customers, a helpful 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.

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. Impinj’s annualized revenue growth of 11.9% over the last two years is below its five-year trend, but we still think the results suggest healthy demand.

This quarter, Impinj’s revenue fell by 3.3% year on year to $74.28 million but beat Wall Street’s estimates by 3.7%. Company management is currently guiding for a 8.8% year-on-year decline in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 1.9% over the next 12 months, a deceleration versus the last two years. This projection doesn't excite us and implies its products and services will see some demand headwinds. At least the company is tracking well in other measures of financial health.

Software is eating the world and there is virtually no industry left that has been untouched by it. That drives increasing demand for tools helping software developers do their jobs, whether it be monitoring critical cloud infrastructure, integrating audio and video functionality, or ensuring smooth content streaming.

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, Impinj’s DIO came in at 238, which is 69 days above its five-year average, suggesting that the company’s inventory has grown to higher levels than we’ve seen in the past.

Impinj had an encouraging quarter, but one earnings result doesn’t necessarily make the stock a buy. Let’s see if this is a good investment. The latest quarter does matter, but not nearly as much as longer-term fundamentals and valuation, when deciding if the stock is a buy.
