Skillful management of employees after a merger or acquisition (M&A) is one of the key aspects to ensuring a successful deal, and most notably to ensure talent retention. This paper aims to describe how Bristol Myer Squibb (BMS) efficiently integrated Celgene after it bought the company for a near-record $74bn in 2019. The authors explain the structural elements applied during the premerger phase (acquisition experience, partner location and portfolio alignment) and the subsequent postmerger decisions to ensure rapid integration (choice of the leadership team, cultural integration and the communication strategy).

This paper adopts a single-case approach of the second largest acquisition in the pharmaceutical industry. It analyzes the management and talent retention decisions taken to ensure rapid integration of Celgene while ensuring that employees felt engaged in the process. This was achieved despite the consideration challenges posed by the COVID-19 global lockdown.

M&As are well known for the HR challenges they generate such as change management, cultural clashes and increased employee turnover. This paper demonstrates how BMS was able to overcome these hurdles, combining a fast speed of integration with managerial dexterity.

This paper offers a concise and clear outline of the management strategies used by BMS to ensure a successful integration strategy. This approach included a strong respect for the human as well as financial and strategic aspects of the deal. For even greater clarity, this paper offers a diagrammatic representation of the strategy of BMS to improve the speed of integration.

Despite the literature highlighting the relevance of mergers and acquisitions (M&As) as strategic options for organizations’ evolution, such events maintain a high failure rate. All stages of M&As generate considerable stress on management accounting systems (MASs) and related actors. This study aims to investigate management accounting change (MAC) throughout M&As to expand knowledge on the technical side of these changes. A deeper understanding of these changes and their relationship to the implementing agents could illuminate the causes of M&A success and failure.

The study uses an in-depth, qualitative case study analysis of two companies that completed an M&A. The MAC process was investigated based on Sulaiman and Mitchell’s (2005) typology. The authors collected information from internal documents, interviews, external reports and public information.

The findings indicate that MAC in M&As represents a comprehensive change that goes beyond the modifications outlined in Sulaiman and Mitchell’s (2005) original framework; the post-deal integration period can be broken down into early and full sub-phases; and the success of the MAC process rests on the different roles played by various change agents.

To the best of the authors’ knowledge, this study is among the first to apply and deepen a MAC framework focused on technical changes to MASs in the context of M&As. To date, the literature on M&A has mainly focused on behavioral or organizational changes while neglecting the technical dimension. In addition, by considering all the stakeholders of MASs, this study’s analyses expose the role of change agents who are not generally considered in the accounting literature.

Cultural friction (CF) was introduced by researchers to overcome the issues and challenges of cultural distance measurement in the context of cross-border mergers and acquisitions (CBMAs). However, this construct has proved itself to be problematic to operationalize. To address this challenge, this paper aims to elaborate on a CF measurement instrument based on individual perceptions in CBMAs. This study used a microfoundation approach to measure CF, relying on managers’ interactions in CBMA settings.

To develop and validate a CF measurement in the context of CBMAs, this study followed a classical procedure including items development, lab tests and one field-study and an assessment of the construct validity.

The final instrument developed for measuring CF is composed of six critical incidents with three associated items each. The factor analysis revealed that the scale used in the field-test measures two factors of CF: internal and external. Reliability and discriminant validity are tested, demonstrating a good discriminant validity of “external” CF. The final measurement can be used as a valid and reliable scale in further studies to assess CF in the context of CBMAs.

This paper’s originality lies in developing and validating a CF measurement instrument that does not rely on cultural distance frameworks. The resulting scale shows the interest in considering micro-individual perceptions – the microfoundation level – for analyzing an organizational phenomenon as culture in CBMA contexts. Using a micro-founded approach, this study offers promising avenues for researchers who wish to study cultural interactions in international settings.

We integrate agency theory and extended resource-based view (ERBV) to examine the impact of business group heterogeneity on the performance of the business group affiliated firms.

The differential ownership structure of business groups (degree of ownership by the promoter, domestic institutional and foreign institutional investors) determines the effect of intergroup heterogeneity, and the differential directors' interlocks (strength and type of directors in the interlocking arrangement) with the affiliated firms assess the impact of intragroup heterogeneity. Acquisition performance is operationalized through cumulative abnormal returns to the acquirer upon acquisition announcement and is computed using the standard event study methodology.

With 476 domestic and cross-border M&A deals announced in India between 2005 and 2021, our findings indicate that the firms affiliated with foreign and promoter-owned groups received positive announcement returns. Furthermore, the type of directors and the interlocks formed therein matter for an affiliated firm. While the affiliate’s executive and the non-executive non-independent directors on the board raise agency issues and negatively impact its performance, the independent directors mitigate them. Further, the market negatively views the interlocks formed by affiliated firms' non-executive, non-independent directors who undertake independent positions in other affiliated firms, as indicated by the negative announcement returns.

To the best of our knowledge, this is the first study to examine the impact of intergroup ownership heterogeneity on the acquisition performance of affiliated firms. Further, evaluating the effect of the type of interlocks in addition to strength is a distinctive feature of this research. This novel aspect of the study attempts to further understand the corporate governance of business groups and its implications, an area often referred to as the “black-box” in the business group literature.

This study uses social exchange theory to describe, explain and propose the influence of dyad partners' leadership position structure, which includes the roles they play and their existing and prospective common experience, on their commitment to their dyad and their cooperation.

The study uses the case of equally empowered co-CEOs in a family business, who play the roles of family member, owner and executive; co-CEOs in a startup firm, who play the roles of owner and executive; and co-CEOs in a merger and acquisition (M&A), who play the role of executive. Co-CEOs in family businesses benefit from longer existing and longer prospective dyad longevity than co-CEOs in startups, who, in turn, benefit from longer existing and longer prospective dyad longevity than co-CEOs in M&As.

The study proposes that the roles the partners play in the dyads, and the existing and prospective longevity of their relationship, positively influence the partners' commitment to the dyad and their level of cooperation.

The study offers a model that has the potential to direct scholars at the formulation of the theory of top management symmetric formal power dyads dynamics and assist family business owners, startup partners, board of directors and co-CEOs in formulating and implementing upper echelons leadership plans to enhance cooperation and coordination between equal partners.

The purpose of this study is to investigate the influence of the target firm’s high-tech status on the share of ownership decision in cross-border acquisitions (CBAs), which is an under-explored topic in cross-border M&A literature.

The authors used Tobit regression and tested the hypotheses using a sample of 7,011 CBA transactions between 1999 and 2014. Inverse Mills ratio was used to address selection bias, and various robustness tests were performed.

The authors found that acquirers seek greater ownership share when acquiring high-tech firms, and that this relationship is moderated by various firm and national level factors. Specifically, the positive relationship between the high-tech status of a target firm and ownership share acquired is stronger when the firms’ primary operations are highly related or there is high formal institutional distance between the firms’ home countries, but it is weaker when acquirers have more prior M&A experience or there is high cultural and geographic distance between the firms’ home countries.

While the topic of ownership strategy in CBAs is advancing, it is still limited, especially when examining acquisitions of high-tech target firms. The authors contribute to the research on CBAs and ownership strategy by focusing on the high-tech status of the target firm, and using a sample of both private and public target firms from 116 countries.

This study aims to identify the strategic factors and their effects on the post-cross-border acquisitions (CBA) technological innovation performance of the acquiring firms. It develops a hierarchical model to examine the interrelationship between identified strategic factors such as strategic flexibility, strategic ambidexterity, environmental dynamism, etc.

This study uses modified total interpretive structural modeling qualitative methodology (m-TISM) to develop a hierarchical model and conducts a Matrice d’impacts croisés multiplication appliquée á un classment (MICMAC) analysis to show the interrelationship between strategic factors affects the acquirer’s post-CBA technological innovation performance. It determines the autonomous, dependent, linkage and independent strategic factors. It further uses comparative case analysis to empirically examine the strategic factors in real-time CBA situations.

This study shows the m-TISM-based hierarchical model highlighting the interrelation, level of autonomy, dependence and linkage among strategic factors affecting the acquirer’s post-CBA technological innovation performance. It suggests that strategic factors such as environmental dynamism, R&D competence, innovation capability and technological capability are largely autonomous and have significant driving power, whereas strategic ambidexterity and strategic flexibility are the connecting factors. post-M&A integration is the governing factor for technological innovation performance in CBA.

The strategists and practitioners could evaluate the key strategic factors having significant driving power for strategy formulation and implementing efficient policies. By implementing the m-TISM model acquiring a firm’s post-CBA performance can be enhanced. Future researchers might utilize quantitative methods like regression and structural equation modeling in the CBA context.

This study uses a novel m-TISM and MICMAC approach to identify the driving and dependent factors affecting post-CBA technological innovation performance. It further provides a detailed theoretical and conceptual understanding relating to the philosophy and establishes an interrelation amongst these under-researched strategic factors in CBA.

Green innovation and green acquisition are key green marketing strategies. This paper aims to explore and compare the drivers of green acquisition and green innovation strategies firms adopt. Moreover, the moderating role of top management team (TMT) sustainability commitment is investigated.

The research model used secondary data based on 1,565 firm-year observations in the beverage and food industry in the US. The two-stage control function approach was used for data analysis.

Media attention motivates firms to pursue both green innovation and green acquisition. The TMT sustainability commitment plays a pivotal moderating role. It strengthens the link between environmental regulation stringency and green innovation but weakens the impact of media attention on green acquisition.

Managers can leverage the study’s findings to guide sustainable marketing decisions in response to environmental regulations and media scrutiny. Policymakers and investors can encourage firms to adopt more sustainable practices, helping align corporate strategies with Sustainable Development Goals 9 and 12.

Though green innovation determinants are extensively studied, most studies rely on surveys or qualitative methods rather than secondary data. Also, as an alternative to developing in-house green technologies or products, the drivers of green acquisition remain unclear despite its growing prevalence. This study addresses both gaps in the sustainable marketing literature.

AI has a leading influence and impact on organizations’ strategies. Yet few studies address how AI tools can impact M&A negotiation and the takeover evaluation stages of firms. Through an in-depth case study, our work questions how such tools can help with key stages of screening and due diligence periods.

We conduct several interviews with founders of the acquiring firm (Group Impact), and we had access to a large amount of information on the launch of the takeover process (including the data room of negotiation documents).

We detail the phases in which AI saved time (nongenerative AI) and, with a view to the future, we detail how a generative version of AI could help in the due diligence and negotiation phases. Also, we address the sticking points that prevented the takeover from being finalized.

First, few studies address the negotiation stage of takeovers as part of these are not finalized and, for the others, researchers are present in the field when the operation is signed. Second, studies that address takeovers that have failed are rare, yet understanding the blocking factors are essential to continue a long-term external growth strategy.

Public data such as news reports, interviews and memos were used to craft the case. In addition, the technical reports released by the National Transportation Safety Board (NTSB), along with secondary data in the form of expert accounts and congressional hearings were used to round out the synopsis of the case study.

This case explores the Boeing–McDonnell Douglas merger and its impact on Boeing’s corporate culture, ethics and strategic decision-making. After the merger, Boeing shifted from a culture focused on engineering excellence to one emphasizing cost-cutting and shareholder value. This cultural shift contributed to the development failures and ethical lapses that resulted in the 737 MAX crisis, which involved two fatal crashes. The case is designed for courses in Strategic Management or Organizational Behavior.
