The impact of securities regulation in the European Union on M&A: Does it compensate to go beyond borders?

Purpose The purpose of this study is to examine the impact of the transposition of the EU directive that regulates M&As on cross-border deals. Acquirers of targets located in the European Union (EU) must comply not only with takeover rules set individually by member states but also with European Council Directives. The most significant of these Directives in the context of mergers and acquisitions (M&As) is the Takeover Bids Directive (TBD). The intent of the Directive is to ensure equal treatment for all companies launching takeover bids or that are subject to a change in control, providing minimum harmonization rules in view of creating a transparent environment for cross-border takeovers. Design/methodology/approach This study uses the event-study and difference-in-differences approaches. Findings Using a sample of 2,129 M&As conducted between 2000 and 2015, this paper finds positive acquisition synergy for acquirers targeting firms from countries with stronger investor protection rules compared to the average of the EU, but no evidence regarding cross-border deals. The results support the prediction that regulation makes countries diverge more depending on their ex ante level of investor protection. Originality/value This study examines the impact of the enactment of the TBD on announcement returns of M&As in the EU.
