The purpose of this study is to examine the impact of Egyptians Acquisitions on the post-performance of the acquired companies from the period of 2003 to 2015 by the use of event study methodology.

By using a non-parametric Mann-Whitney-Test that can replace the unpaired ttest in the case of small samples, in addition to the factor analysis. The Study tests the significant difference between performance of the acquired companies before and after the acquisition. Empirical results for the whole sample showed a negative significant difference between both the profitability and the capital structure performance of the acquired companies before and after the acquisition. On the other hand, it showed an insignificant difference between both the liquidity and the activity performance of the acquired companies before and after the acquisition. Studying the sub-industrial sectors shows that the Industry Sector has an impact on the performance of the acquired companies and that appears in The Basic Resources and Utilities Sub-sector liquidity, profitability and capital structure performance and has no impact on financial activity performance.
