In the present era, every organization is anxious to enhance their productivity and performance. The success and sustainability of a business are possible through corporate performance, which helps fulfill organizational goals. The present study examines the effect of organizational culture (mission, involvement, consistency, and adaptability) on corporate performance in Egyptian manufacturing firms. The study is quantitative, and the firework is based on well-known studies like Kwarteng and Aveh (2018), Abukari et al. (2023), and Junca Silva and Pinto (2024). The study employed quantitative methods, where data were collected from employees of Egyptian manufacturing firms due to their consideration as valuable sources of organizational success. Finally, the study utilized 332 valid samples to infer the results. Through analysis of moment structures (AMOS), the path analysis suggests a positive effect of mission, involvement, and adaptability on corporate performance. On the other hand, consistency is a negative predictor of corporate performance in Egyptian manufacturing firms. The study findings would benefit policymakers and planners in enhancing the organizational culture to improve corporate performance, specifically among manufacturing and small and medium-sized enterprise (SME) firms in the developing context.
