This dissertation collects data from 3,193 mergers and acquisitions that meet three conditions: the transaction was completed between 1994 and 2016, the target company is Brazilian and at least one of the companies involved is publicly traded. The main contribution of the dissertation consists of answers to five questions about the mergers and acquisitions market in Brazil. i) the documented market multiple is high: median of 9.33 for the Company s Economic Value ratio over its EBITDA, while in the same period the median of this multiple for all Brazilian publicly traded companies is 6, 92; ii) 64 percent of the transactions in the sample were horizontal, that is, they involved buyers and sellers operating in the same industry; iii) in 51 percent of the transactions in the sample, foreign investors acquired Brazilian companies; iv) loans subsidized by the Brazilian government are present in 73 target companies from the 218 mergers and acquisitions in the sample that involved exchange of control and in 41 acquiring companies; and v) an increase of one percentage point in real GDP increases the real financial volume involved in mergers and acquisitions transactions by 14.7 percent. The data suggest that the activity in the Brazilian merger and acquisition market is motivated by a search for increase of market power or by expanding the performance of foreign companies in the Brazilian market. The presence of subsidized loans in the balance sheets of the acquired companies indicates that financial motivations for the transactions are also relevant.
