The investment industry in special purpose acquisition companies is a relatively new industry, and academic research focused on the effects of investing in these companies is increasing. A special purpose acquisition company (SPC) is a company that finances a target company through an initial public offering of its shares with the aim of acquiring a target company within a specified period of time. The target company is usually a private company that automatically becomes a public company (public joint stock company) after being purchased by the SPC. In this study, by first examining the theoretical foundations of the research, a comprehensive understanding and study of all dimensions of special purpose acquisition companies with a comparative approach has been carried out and an initial model of special purpose acquisition companies has been developed. Then, using semi-structured interviews and a questionnaire, the legal structure of these companies has been examined in accordance with the Iranian capital market. Finally, based on the content analysis and analysis of questionnaires collected from experts, and after extracting the results from the questionnaire, comparative study, and review of existing samples, the legal structure of special purpose acquisition companies has been designed.
