Impinj shares plunge over 30% after weak Q1 outlook

Shares of Impinj, a Seattle-based maker of RFID technology, fell more than 30% after the company issued a much weaker-than-expected forecast for the first quarter of 2026, rattling investors.

The company reported fourth-quarter revenue of $92.8 million, slightly higher than a year earlier and broadly in line with expectations. Earnings came in at $0.50 per share, just below analyst forecasts.

For the first quarter, however, Impinj expects revenue of only $71 million to $74 million, well below Wall Street estimates of nearly $90 million. Projected earnings per share are also modest, ranging from $0.08 to $0.13.

According to the company, the soft outlook reflects short-term headwinds, including inventory reductions by retailers, weaker demand from apparel customers, and shifts in customer ordering patterns. These factors are weighing on near-term sales, despite longer-term confidence in RFID adoption.
