I examine the market reaction to merger announcements and the long-term post-merger stock price performance of newly merged firms. For a sample of 484 acquiring firms completing mergers between 1993 and 2000, the average value-weighted abnormal announcement date return (market-adjusted) is a statistically significant -1.02%. On average, this reaction is more negative for firms with "good governance." Specifically, a governance index comprised of three governance variables is significantly negative in a multivariate regression of announcement date abnormal returns. Comp is the percentage of CEO salary consisting of equity incentives (including stock options and restricted stock grants), InsideOwn is the percentage of the firm owned by officers and directors, and InstOwn is the percentage of the firm owned by large outside block shareholders. Value-weighted calendar-time portfolios consisting of the full sample of acquirers exhibit significant abnormal returns of 9.12%, 33.84% and 55.8% for the 12, 36 and 60 months following the merger, respectively. This overperformance is limited to the value-weighted portfolios. There is calendar-time evidence of abnormal performance for some subsamples on a risk adjusted basis. However, when compared to a control group, abnormal performance is limited to large glamour acquirers on a 12-month horizon, large cash acquirers on a 36 and 60-month horizon, and small focusing acquirers on a 60-month horizon. Multivariate analysis of long-run returns reveals that use of equity and corporate diversification are associated with lower post-merger performance. With regard to governance and long-run stock returns, there is also evidence that suggests higher levels of incentive compensation for CEOs is associated with more successful merger transactions for long-term investors.

Syftet med den här magisteruppsatsen är att undersöka hur tillkännagivandet av företags-förvärv påverkar aktieavkastningen på ett uppköpande bolaget. Testet är begränsat till före-tag som enbart är listade på Stockholmsbörsen under perioden 1996 till 2005. För att testa onormal avkastning användes marknads modellen. Resultatet visade att tillkännagivandet av företagsförvärv har en signifikant effekt på avkastningen för aktien för det bolag som ska förvärva. Majoriteten av uppköpande bolag upplevde en negativ onormal avkastning under test perioden (100 dagar före tillkännagivandet och 100 dagar efter). / The purpose of this master’s thesis is to examine the effect a corporate takeover an-nouncement has on share prices for acquiring companies. The test will only involve com-panies listed on the Stockholm Stock Exchange during the period 1996 to 2005. To test the effect an announcement has, abnormal return for a period before and after the takeover announcement was calculated. The findings from the testing showed that takeover an-nouncements have a significantly impact on shareholder return. The majority of acquirers in the sample had negative average abnormal returns during the event period (100 days prior to the announcement and 100 day after).

This study examines the short-term shareholder wealth effects to U.S. bank mergers and acquisitions (M&As) that were announced and completed between 1989 and 2004. Using various event windows, the cumulative abnormal returns (CARs) to target firms are positive, bidder firm abnormal returns are negative, and the combined CARs are positive. This result is consistent with the synergy and hubris hypothesis wherein bank M&As are wealth-creating events as synergies exist; however, bidders may overpay to realize these gains. <p>The M&As are examined by the method with which they are financed, namely, cash, or a combination of cash, stock, and/or debt, versus stock only. The target, bidder and combined mean CARs for M&As that are financed by a cash or combination payment are higher than those that are financed by stock for the full sample period and the 1999 2003 sub-sample period. Furthermore, the results indicate a positive and statistically significant relationship between the bidder and combined CARs and cash or combination payments. <p>Further evidence presented suggests a positive and statistically significant relationship between the target CARs and whether the M&A is geographically focusing (intrastate), with no corresponding relationship existing for the bidder and combined firms. Results, however, do indicate that the mean combined CARs are higher for intrastate compared to interstate M&As. In addition, the target, bidder and combined CARs are driven in part by the relative size of the merger parties.

This study examines macroeconomic and industry-level factors (with particular emphasis on the business cycle) on industry-level merger activity. In a sample of US mergers from 1979 to 2006, we find that industry level mergers are highly pro-cyclical. The business cycle has a positive and significant impact on both horizontal and non-horizontal mergers, even after controlling for other macroeconomic and industry-level effects. Although macroeconomic variables have similar effects on both horizontal and non-horizontal mergers, industry-level factors vary significantly between the two types of mergers. Horizontal mergers are much more aligned with neo-classical theories, while non-horizontal mergers are more affected by financing constraints and overvaluation. We also find that the determinants and financing preferences of industry-level mergers vary greatly across the business cycle stages, which suggests that the motivation for mergers changes in different economic conditions.

Background Synergies or rather the absence of synergies has been blamed for many failures in regards to mergers and acquisitions. Still, there are companies using mergers and acquisitions as a natural part of their growth strategy, indicating that these organizations manage to handle synergies efficiently. Purpose The purpose of this study is to analyze synergies in regards to mergers and acquisitions in technical trading companies to learn about success factors. Method Because of synergies’ complexity this study has used a qualitative approach. The empirical findings have been compiled by semi-conducted interviews with company representatives from the organizations regarded in the study. Conclusion The conclusion points at several success factors in regards to synergies and mergers and acquisitions. However, the three most important were found to be; the entrepreneurship and human capital, the corporate head’s knowledge, the experience and selection capability and the inclusion of acquisitions (developed from the urge for growth) in their business models.
