This paper takes a contingency approach to investigate whether there are market performance variations for different types of M&A. Eight different types of M&A are identified in a typology based upon the conjunction of three contextual dimensions: external environmental, acquiring firm level strategy and CEO motivation.  Drawing upon a sample of 1,926 domestic UK deals we evaluate the typology to determine whether the financial markets distinguish between different types of M&A. Results indicate significant market and risk-adjusted performance differences by M&A type. These confirm that a contingency approach to M&A performance has merit. We suggest that the proposed integrated typology, that recognises the importance of multiple aspects of strategic fit to M&A performance, addresses the paradox that M&A practitioners continue to pursue deals despite widespread acceptance that they result in high failure rates.

Post-acquisition integration matters for overall M&A outcome. However within this phase researchers have struggled to identify clear links between integration activities and post-acquisition outcome. This may be due to using organisational levels of analysis, where sub-organisational issues serve to confound findings. In order to unpack the post-acquisition phase, and to delve more deeply into organisations, this paper adopts a more granular perspective on integration activities by focusing upon the building blocks of organisations. Specifically we investigate ordinary routine amalgamation and their impact upon meta-routine outcome during acquisition integration. Drawing upon two longitudinal integration cases and using ‘retroductive’ analysis, two types of amalgamation are identified, namely ‘combination’ and ‘superimposition’. We find that, while the basic nature of routines, such as multiplicity and nestedness, inhibit routine amalgamation, external interference in the form of context, structural change or introduction of additional routines is needed to stabilise amalgamated routines. From our findings we are able to suggest a number of testable propositions about the factors that influence the amalgamation of routines. This empirical study contributes to the M&A literature by opening up the ‘black box’ of post-acquisition integration by providing details at a granular level of what actually happens during integrations.
