Revenue Growth
Examining a company’s long-term performance can provide clues about its quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Over the last five years, Impinj grew its sales at an excellent 18.8% compounded annual growth rate. Its growth beat 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.
We at StockStory place the most emphasis on long-term growth, but within semiconductors, a half-decade historical view may miss new demand cycles or industry trends like AI. Impinj’s recent performance shows its demand has slowed significantly as its annualized revenue growth of 8.6% over the last two years was well below its five-year trend. 
This quarter, Impinj reported year-on-year revenue growth of 10.7%, and its $108.4 million of revenue exceeded Wall Street’s estimates by 3.5%. Adding to the positive news, Impinj’s growth inflected positively this quarter, news that will likely give some shareholders hope. Company management is currently guiding for a 11.4% year-on-year increase in sales next quarter.
Looking further ahead, sell-side analysts expect revenue to grow 12.1% over the next 12 months. While this projection implies its newer products and services will spur better top-line performance, it is still below the sector average.

AI chip stocks trade at ridiculous valuations. This company processes a trillion consumer signals monthly using AI and trades at a third of the price. The gap won’t last. The institutions will figure it out. You need to see this first. Read the FREE Report Before They Notice.
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, Impinj’s DIO came in at 186, which is 12 days above its five-year average. These numbers suggest that despite the recent decrease, the company’s inventory levels are higher than what we’ve seen in the past.
