Case Background:

On August 27, 2018, the initial complaint in this securities class action was filed against Impinj, Inc. (“Impinj”), and certain of Impinj’s directors and officers, asserting violations of sections 10(b) and 20(a) of the Securities Exchange Act.

The complaint alleged that, during the class period, the defendants made materially false and misleading statements or material omissions about the capabilities of the Impinj Platform. The complaint further alleged that the price of Impinj’s common stock was inflated during the class period as a result of the defendants’ misstatements and omissions.
