Recognizing the necessity of regulating the company acquisition process, the Acquisition and Control Regulation No. (2/2019) was issued, given the prevalence of this strategy among various economic entities to achieve their objectives. This thesis aims to examine the Omani regulation of the acquisition process and compare it with the regulations of Arab and foreign countries that preceded Omani legislation. The objective is to evaluate the adequacy of the legal framework governing this process in Oman. Additionally, the study seeks to elucidate the effects of the acquisition process on its stakeholders, whether directly involved or indirectly affected. The study begins with a preliminary chapter that explains the nature of the company acquisition process, followed by a discussion on the legal mechanisms for company acquisition. The final chapter is dedicated to outlining the effects arising from the acquisition process on companies. The researcher concluded that the primary aim of the company acquisition process is to gain control of the target company. This process could lead to economic concentration and potentially result in monopolization if not adequately regulated by the state. A comparison of Omani regulations with those of other countries reveals that other nations have included provisions exempting the acquirer from making a mandatory acquisition offer if they intend to acquire a controlling stake in the target company. These countries have experienced numerous acquisitions in their markets, enabling them to amend relevant legislation to achieve comprehensive regulation of the acquisition process.
