This research sought to explore the mission statement drivers and content of Egyptian SMEs. It investigated the relationship between the mission statement as a set of drivers and financial performance, and whether triple bottom line (TBL) mission statements achieve their ends in terms of financial success or not. Moreover, it examined the moderating role of CSR in the relationship between mission statement and financial performance. To achieve the research purpose, six research questions have been asked and five research hypotheses have been developed. Quantitative data has been collected to achieve this research purpose and the deductive approach has clarified the road map for the researcher. The research develops a conceptual framework depending on two important theories (competitive advantages theory and triple bottom line theory), then moves to an empirical study and tests the previous set of hypotheses. A postal questionnaire survey was the suitable choice for collecting data because of the nature of the research context (Egyptian SMEs) which is very wide and has a great many SMEs. Using structural equation modelling methodology, based on a sample of 298 manufacturing SMEs operating in food production in Egypt, the study emphasized no difference between the mission statement drivers and content demonstrated by the literature in other geographical domains. There are four main results. First, the contents of the mission statement can be seen as a consequence of mission statement drivers. Second, the effect of the mission statement as a set of drivers on the financial performance cannot been emphasized. Third, the TBL mission achieves its ends in terms of financial success. Finally, with respect of the Egyptian context, the financial success can be enhanced by the mission statement through the firm’s commitment to CSR practices. This study has contributed to the theory by asserting mission statement drivers and content in a new context. None of the studies investigated the link between mission statement drivers and contents, which has been contributed by this study. Furthermore, it has introduced the term Triple bottom line mission that contributes to the financial success. Moreover, it has provided an explanation for the indirect relationship between mission statement and financial performance through the firm’s commitment to CSR practices. Equally important, this study contributes to the practice. Thus firms, in order to gain and maintain an effective mission statement that enhances financial success, need to make three sequential steps. Firstly, firms have to understand why they have or should have mission statements and promote these rationales among all the organization’s members. Secondly, develop their mission statement to be consistent with the purposes or rationales for developing it. Thirdly, firms have to practice what they preach in their mission statement through the commitment to CSR practices.
