Hållbarhet inom företagsförvärv : En jämförelse av påverkan på abnormal avkastning inom förvärvande företag vid tillkännagivande av företagsförvärv inom tre branscher

Sammanfattning: This study examines whether there is a difference in the impact on the cumulative average abnormal return (CAAR) when announcing merger and acquisitions for companies that are members and companies that are non-members of UN Global Compact. Furthermore, the study examines the development of CAAR by dividing the acquiring companies in the financial-, industrial-, and high-technology industries. To examine this, a quantitative method with an event study is applied. In total, CAAR is examined for 204 acquisitions where 102 acquisitions are announced by companies that are connected to UN Global Compact 10 principles. All of the acquisitions have been announced between the period 2009-01-01 to 2019-12-31. The hypotheses regarding differences in abnormal returns in the financial, industrial and high-technology industry have been tested in a significance tests and presented in tables and graphs. The results of the study shows that companies that are members, regardless of industry, are negative affected by the announcement of merger and acquisitions. Furthermore, there is differences in how CAAR for members and non-members are affected by the announcement of acquisitions depending on the industry in which the companies are located. The conclusion is that non-members present the highest values of CAAR in all industries but significance can only be showed in the industrial industry. Significance can be showed for members in all industries.
