Cary Baker, Chief Financial Officer of Impinj, Inc. (PI), received a grant of 6,958 restricted stock units (RSUs) on 08/20/2025. Each RSU converts to one share of common stock and was granted at no cash price ($0). Following the grant, the reporting person beneficially owns 6,958 shares directly. The RSUs vest one-fourth on 08/20/2026 and then 1/16th of the grant each quarter thereafter, contingent on continued service. The Form 4 was signed by an attorney-in-fact on 08/21/2025. The filing discloses a routine executive equity award intended for compensation and retention; no cash exercise or sale occurred.

The reported transaction shows the RSUs were granted at a $0 exercise price and are held directly by the reporting person.
