Abstract There is a lack of extended knowledge on internationalization theories applied to developing countries firms (DCF) within the international business field. This paper explains the drivers of the international investment behavior of world leader baking company Bimbo and the relevance that the main internationalization theories have in the foreign direct investment (FDI) decisions. Ownership, Locational and Interna-lization (OLI) advantages, as well as the Uppsala model, will be explained and compared to the Bimbo's internationalization path. Furthermore, Bimbo's international operations are summarized and presented chronologically. Finally, a comparison between the above mentioned theories and the company's behavior is provided, and the conclusion that Dunning's (2000) eclectic paradigm explains the firm's internationalization is suggested.
