Based on the theory of planned behavior, this study investigates how the listing-decision variables (earnings forecast, word of mouth communication, and elements of corporate governance) affect the behavioral variable (listing decision), with the attitude variable (listing intention) being the mediator. Based on a sample drawn from companies listed on the Khartoum Stock Exchange, data were collected through a questionnaire. The data were analyzed using descriptive statistics, factor analysis, reliability, and regression. The findings support the theoretical framework, indicating that the listing-decision variables are significant in shaping the attitude variable. The listing intention significantly affects the behavioral variable. The study finds that listing intention significantly mediates between listing decision and earnings forecast, but not between listing decision and word of mouth communication or elements of corporate governance. The results support the conclusion that mediation between earnings forecast and listing decision affects the listing intention, so Sudanese companies should increase their intention to list, which would develop their relationship with the Khartoum Stock Exchange.
