Nowadays, organizations face increasing demands for reliable information. However, a question resides in how these organizations respond when facing adverse circumstances that may impact their corporate image and overall value. Thus, we analyze whether, given the circumstances arising from the Mariana and Brumadinho dam accidents, the Brazilian company Vale used its corporate reports to clean up its corporate image or manipulate the external perception of the events. To achieve this objective, a comprehensive analysis of corporate reports issued by Vale from 2010 to 2021 was conducted. This analysis focused on identifying impression management strategies employed by the company. The goal was to scrutinize Vale’s conduct before and after the accidents, as well as during their occurrence. Evidence was found of the adoption of strategies, mostly defensive, such as internal attribution and denial during Mariana’s accident; and apologies, restitution, denial, and improvements during Brumadinho’s accident.
