Canaccord analyst T. Michael Walkley noted Impinj reported better than expected Q4 results and its second consecutive quarter of record revenue and record system sales. The analyst said with the improving channel inventory and solid results, he expects a return to double digit year-over-year growth. He believes in the long term prospects for the RAIN market as it remains strong, as does the strong long-term growth potential across retail, healthcare, and other large markets benefiting from RAIN RFID solutions. Walkley reiterated his Buy rating and $31 price target on Impinj shares.
