This study emphasized the influence of entrepreneurial orientation on export performance with the mediating role of environmental uncertainty on Ethiopian garment manufacturing companies. One hundred seventeen respondents are solicited to respond using standardized questions. Through the AMOS v23 program, we conducted structural equation modeling approaches that met the dimensions of variable validity and reliability. According to the study's findings, entrepreneurial orientation has a negative, significant association with export performance. Risk-taking, similarly, was significantly associated with export performance. Environmental uncertainty is found to be a non-mediating variable between entrepreneurial orientation and export performance. Innovation, proactiveness, and risk-taking are found to be second-order factors of entrepreneurial orientation. Similarly, dynamic and magnificent make up the first order of environmental uncertainty. The study suggests the inclusion of entrepreneurial orientation elements in strategic plans, outsourcing tasks, as well as capacity building for employees of the garment companies.
