This study investigates what impact mergers and acquisitions have on bank efficiency by examining both pre-merger and post-merger performance. Specifically, the research looks at the effect of bank efficiency on shareholder wealth creation upon bank merger announcement. The study finds supportive evidence that the market takes into account the pre-merger bidder bank’s efficiency in adjusting the bank stock’s price at the time of announcement. This suggests that bank efficiency has a significant positive effect on shareholder wealth creation when a merger is announced. Furthermore, in reacting to the announcement, the market also perceives the prospects for future enhancement of bank efficiency as a result of the current event. Thus, post-merger bank efficiency is found to also contribute to shareholder value creation on merger announcement. In particular, the study finds evidence suggesting that post-merger profit efficiency, rather than cost efficiency, has a positive effect on cumulative abnormal returns. The study investigates 56 commercial bank mergers that took place in 22 European countries between 2001 and 2007. The event study methodology is used to determine shareholder wealth creation, employing the market model in estimating expected returns. Efficiency is estimated using the parametric stochastic frontier approach. Performance improvement in the combined firm is obtained by comparing post-merger efficiency with pre-merger efficiency, which is the sum of bidder and target efficiencies after weighting them based on their pre-merger total assets. To find out whether efficiency has an effect on shareholder value creation, regression analyses are performed involving cumulative abnormal returns, a few efficiency variables, and a number of control variables. The main finding of this study is that pre-merger bank efficiency contributes to short-term shareholder value creation upon merger announcement. Some evidence is also found that post-merger bank efficiency has a positive effect on shareholder value creation at announcement time which is associated more with profit efficiency than with cost efficiency. Also, as the study finds statistically significant positive cumulative abnormal returns, the results of this study are supportive of the view that, increasingly, European merger studies that examine post-2000 data find that bank mergers are value-creating even for the bidding firms. Evidence that pre-merger bank efficiency has a positive effect on cumulative abnormal returns, and that the market takes into account perceived future bank efficiency on merger announcement, underscores the importance of efficiency as a performance measure. If how the market reacts to a merger announcement reflects future efficiency performance, shareholders, policy makers, and other stakeholders may be able to take that as one of the factors on which they can base their decisions regarding the yet uncompleted merger. They can also use previous efficiency records for predicting short-term and long-term performance of prospective parties to a merger before announcement.
