Today’s business environment is characterized by a growing number of knowledge risks. There has been a paucity of empirical research on the impact of knowledge risks on business sustainability. This paper looks at the direct and indirect consequences of knowledge risks on a firm\u27s sustainability. A questionnaire was administered with a sample of 427 respondents from Lebanese knowledge-intensive firms. Structural equation modeling (SEM) was used to test the research framework. The findings indicate that knowledge risks and knowledge loss have a direct and significant detrimental impact on business sustainability. The performance of organizations has a direct and significant positive impact on sustainability. The mediating effect of organizational performance in the relationship between knowledge risks and sustainability of the business was demonstrated. However, the link between human knowledge risks and both organizational performance and sustainability was not significant. Outcomes of the study will persuade knowledge-intensive firms’ managers to deploy knowledge management approaches and reduce potential knowledge risks
