A Work Project, presented as part of the requirements for the Award of a Masters Degree in Finance from the NOVA – School of Business and EconomicsThis project started as an M&A Field Lab, where students are challenged to advise the selected company (Mota-Engil) on typical M&A proposal from an investment bank perspective. However, during the Field Lab path, the source of information to university students proved to be limited, specially in what concerns the searching for an operation abroad. Nevertheless, along the way, I tried to understand the reason why Mota-Engil’s shares were being so bearish in the stock market. So, this project reflects the investigation I did to justify the market valuation of Mota-Engil, to which I proposed opposite solutions to turnaround the negative performance. All the analysis refers to the year end of 2010 and it is important to state that companies’ valuations were done as the base to understand possible changes on corporate value
