How do international investors react to announcements of cross-border mergers and acquisitions (CM&As) by emerging market multinational enterprises (EMNEs)? Using a unique and manually-constructed firm-level dataset, this paper examines the stock price reactions to CM&A announcements made over the period 1991–2010 by Chinese MNEs listed on the Hong Kong Stock Exchange and the wealth impacts of their corporate governance. Our empirical findings confirm a positive stock price reaction on average, and suggest that international investors react positively to the presence of large shareholders, but negatively to the presence of institutional shareholders. There is a negative impact if the largest shareholder is either the State or the corporate founder. We suggest that this is because the international investors perceive potential principal–principal conflicts in such ownership/control constellations and discount equity prices accordingly. We also find that Board size and independence have positive effects on the price reaction, but that large supervisory boards engender negative reactions.
