While organizational stigma has emerged as an important and vibrant area of study, yet the processes of stigmatization have not been as thoroughly examined. Specifically, this study explores the subsequent, ongoing stigmatization processes beyond stigma emergence that are triggered by stigma transfer. To do so, we draw on a qualitative case study of an American university selling the naming rights of its newly built football stadium to a company that runs for-profit prisons with a history of human rights violations. We find that the stigma transfer through an exposed association can lead to amplifying stigmatization of both the source and target organizations, featuring a reverberation process fueled by both rhetorical and material stigmatizing practices. Even after the stigmatizing association ceased, stigmatization of the target organization, though muffled, lingered and required further management. Through developing a model of amplifying and muffling stigmatization after stigma transfer, we offer contributions to scholarship on ongoing stigmatization and stigma transfer. We also open the opportunity to understand the temporal dimensions of stigmatization.
