Purpose
– This paper aims to illuminate the issue of whether there is a significant difference between long-term abnormal return of acquirers across industries, and which industries achieve better returns.

Design/methodology/approach
– This paper investigates whether there is a significant difference between abnormal return of acquirers across industries. The impact of timing of the deal on the acquirer returns is also studied in this paper. In the regression analysis, we control for acquirer’s size along with a number of deal characteristics, such as method of payment, the mode of the acquisition, the diversifying nature of the deal and value of the deal, to examine whether the differences in acquirer returns across industries persist when these factors are taken into account.

Findings
– The results of the study propose discrepancy in acquirers’ long-term abnormal returns across industries. While a number of industries, such as petroleum and natural gas, insurance and machinery, experienced significantly positive abnormal performance, others like business services and medical equipment have demonstrated significantly negative long-term returns.

Originality/value
– This paper investigates the industry impact on performance of acquirers. The results of this research provide more comprehensive evidence from all of the industries that have been involved in mergers and acquisition deals during the period 1981-2007 so that the returns of different industries can be compared. Most importantly, the evidence rejects the equality of mean abnormal returns across industries at significant levels.
