Purpose This paper aims to analyze concealment and deception in self-defeating organizational crisis response strategies and the possible consequences of their adoption on a company’s reputation. It represents an example of where every guideline to address stakeholders after a crisis was dismissed. Design/methodology/approach This paper investigates a major environmental incident that took place in Colombia in 2013 and studies how the responsible company responded to the incident through the examination of company reports, media statements and national and international newspaper articles. Findings The analysis shows that in addition to environmental damage, the company’s reputation was affected by the way the company responded during this crisis. Research limitations/implications The outcomes highlight the importance of the manner in which a crisis response is managed, as these types of mistakes often aggravate reputational damage. Practical implications This paper is an invitation for companies to be quick, consistent and transparent with their responses when facing their stakeholders in moments of crisis. Not doing so may aggravate not only social but also economic and environmental impacts. Originality/value Contrary to other contributions on the subject, this study implies that a misleading crisis response, including concealment and deception, can be an even greater challenge to a company’s reputation than the crisis itself.
