The Impact of Organizational Culture on Post-M&A Profitability: A Quantitative Study of Nordic Small-Cap IT Acquirers

Abstract

The recent rise in mergers and acquisitions (M&As) activity reflects the growing opportunities for expansion in an increasingly technology-driven world. Despite this potential, an estimated 70 to 90 percent of M&A transactions fail to meet expectations. Research often identifies organizational culture as a key risk factor, with misalignment in organizational culture contributing to approximately 30 percent of failed deals. This issue is critical for smaller IT firms, where organizational culture plays a central role in maintaining competitive advantage. This thesis employs an OLS regression approach to examine the extent to which alignment in organizational and national culture influences post-M&A profitability in Nordic small-cap IT firms. The analysis is grounded in three theoretical frameworks: the Resource-Based View (RBV), Post-Merger Integration (PMI) theory, and Hofstede’s cultural dimensions theory, which inform the development of the study’s three hypotheses. These hypotheses are tested using independent variables that capture the alignment in organizational culture (horizontal compared to cross-industry M&As), in national culture (domestic compared to cross-border M&As), and national cultural distance based on Hofstede’s dimensions, as predictors of post M&A profitability measured by Return on Assets (ROA). A dataset of 54 Nordic IT acquirers involved in M&A transactions between 2010 and 2021 was analyzed. Across seven OLS regression models, including a main analysis and two robustness tests, none of the independent variables significantly predicted post-M&A profitability. Instead, the internal firm-specific characteristics of the acquirer, such as firm size, ROA, and capital structure, measured before the M&A, emerged as the primary drivers of post-M&A profitability. These results challenge the traditional belief that cultural alignment leads to higher post-M&A profitability and instead highlight the significance of integration capabilities and the ability to reconfigure resources with flexibility. The study contributes to the M&A literature by offering a capability-based and process-oriented perspective on integration success, particularly in innovation-driven industries such as IT.
