Due to rapidly changing in economic, political and human issues and increasing environmental problems in the world, companies are forced to face and adapt to the new dynamics of business life. These developments result in many changes in global and local levels. Especially in the aftermath of the global financial crisis, it is believed that nothing in the economy will ever be the same again. This time period includes inadequate international economic system, rapid fluctuation in world economy, chaotic areas, high unemployment rates, etc. This cyclical trend is called as "new normal" by some authors. For this era, it is assumed that new economic norms and requirements will bring their effects on the business community. Therefore, this challenging requires partnerships of companies. They have to cope with new actors of competition. They achieve competitive advantage by making alliance or mergers and acquisitions by sharing their core competencies with each other to survive and to develop in the new world form. In this study, we will use the annual mergers and acquisitions review reports (2007-2011) published by Deloitte. In this study, we expect that this issue will focus attention on the new challenges facing companies in the new normal in terms of mergers and acquisitions. The paper will show possible results of these events in future and their effects on companies and government or economical conjuncture. We believe that the paper will lead to relevant research in the future.
