O processo de due diligence financeiro e fiscal

: criação de valor

Abstract

The Due Diligence process plays a central role in mergers and acquisitions (M&A), being essential for assessing the risks and opportunities associated with the target company. This dissertation aims to analyze whether the Due Diligence process, with a focus on its financial and tax dimensions, contributes to value creation in M&A transactions. To achieve this, a literature review was conducted on the concept, motivations, benefits, and causes of failure in such operations, followed by the application of a questionnaire to professionals and investors with experience in the sector. The study adopted a qualitative methodology, based on the descriptive and interpretative analysis of the responses collected. The results indicate that Due Diligence is perceived as a key instrument for risk mitigation, enhancing decision-making confidence and ensuring transaction integrity. It was also observed that, in several cases, the findings of the Due Diligence process led to the withdrawal from the transaction, thus preventing potential losses. It is therefore concluded that Due Diligence, in addition to enabling a better understanding of the target company’s real value, acts as a mechanism of protection and strategic guidance, significantly contributing to the success and sustainability of M&A operations.
