Purpose: The purpose of this paper is to analyse the impact of ESG ratings on IPOs performance in the form of underpricing. It is also analysed whether the existence of neutral or positive ESG ratings has an impact on underpricing. In addition, it will also be analysed whether the degree of ESG rating influences the underpricing within the rated companies. The aim is to make a contribution that can lead to a further reduction in information asymmetries on the capital markets and analyse the effects of signals. Design/Methodology/Approach: The RepRisk rating of approx. 360 sub-frames is used to determine the influence of these variables on the underpricing with the help of a linear regression. Control variables are used to consider influencing factors that have already been researched. The influence of these variables on underpricing is then determined in a linear regression analysis. Statistical robustness tests validate the results. Findings: An all-encompassing statement on the question of whether ESG ratings as part of the IPO process can lead to a reduction of information asymmetries or be a qualitative signal regarding the Signaling Theory. Originality/Value: This paper provides new and important insights into the relationship between ESG ratings and the underpricing phenomenon. It is intended to support existing theories.
