<jats:p> – The results of this study reveal that M&As in the absence of antitrust laws could be driven by managerial self-interest to create market power instead of realizing synergistic gains. Also, in Malaysia, the non-merging rival firms have significantly higher productivity improvement than the control bidder firms, and therefore, this study has identified the spillover effect as a behavior of M&A reaction. </jats:p>

<jats:p> – This paper differs from previous studies in that it attempts not only to examine the real long-term gains of horizontal M&A activities in Malaysia but also the spillover effects of M&A activities on similar but non-merging firms.</jats:p>
