Shares of Impinj (NASDAQ: PI) skyrocketed on Thursday, peaking at a 34.5% gain just after 1 p.m. ET. The maker of chips and systems for RAIN RFID item-tracking systems posted second-quarter results on Wednesday evening, stumping analysts on both the top and bottom lines.

Impinj's Q2 2025 by the numbers

The report wasn't perfect. Revenues fell 4.5% year over year to $97.9 million, and adjusted earnings dropped from $0.83 to $0.80 per diluted share. However, your average analyst would have settled for earnings near $0.71 per share on revenues in the neighborhood of $93.8 million. The reported results also exceeded the top end of management's guidance ranges across the board.

Impinj's latest products play well together

Impinj saw strong demand for every product category, from signal readers and data management gateways to RFID endpoint tags. Clients are finding new use cases for Impinj's item-tracking solutions, and the recently released next-generation readers and endpoints are inspiring stronger demand for each other. That's a classic synergy between two groundbreaking products that work especially well together.

Looking ahead, Impinj's management expects continued revenue growth in the third quarter, though bottom-line targets were modest due to the unpredictable economy. Impinj has a history of setting low targets and then beating them easily, and this is probably another example of that underpromising approach.

After Thursday's jump, Impinj's stock stands 158% above the 52-week lows it reached in April. It's also priced 34% below October's all-time highs. The stock isn't cheap, and the business growth has been choppy recently, so I'm not exactly a buyer at this point. Still, Impinj's item-tracking technology looks more useful every year, and I'm keeping a close eye on this company. I might pounce on this volatile stock in the next price dip.
