Impinj Inc. (PI) experienced a significant intraday decline of 17.63%, as the stock market reacted sharply to the company's latest financial guidance.

The sell-off was primarily triggered by a disappointing outlook for the first quarter of 2026. Despite reporting fourth-quarter adjusted earnings per share that met analyst estimates and revenue that slightly exceeded expectations, the company forecasted a significant sequential drop in revenue for Q1 2026. The guidance range of $71 million to $74 million represents a notable decrease from Q4's $92.8 million, and the projected adjusted EPS of $0.08 to $0.13 fell well below analyst expectations.

Following the earnings release, several analysts adjusted their price targets for Impinj. Piper Sandler cut its target to $180 from $230, while Roth Capital lowered its target to $220 from $235, reflecting concerns over the company's near-term growth prospects and continued losses indicated in the guidance.
