London, UK – July 30, 2026 – Morgan Stanley has emerged as the preeminent financial advisor in European mergers and acquisitions (M&A) for the first half of 2026, commanding an impressive $128.3 billion in advised deal value. This significant valuation achievement underscores the investment bank’s strategic prowess and deep market penetration. Concurrently, Rothschild & Co has solidified its position as the most active advisor by transaction volume, orchestrating a remarkable 48 separate M&A deals during the same period. These findings, released today by GlobalData, a leading data and analytics company, provide a comprehensive snapshot of the European M&A advisory landscape in the first half of the year.
The H1 2026 European M&A advisory league table reveals a dynamic marketplace where different firms excel in distinct metrics. Morgan Stanley’s triumph in deal value is a testament to its ability to secure and execute high-stakes transactions, often involving substantial capital outlays and complex financial structuring. This performance not only highlights their advisory capabilities but also suggests a strong network of corporate clients and a keen understanding of market opportunities in the current economic climate.
Morgan Stanley’s Value Dominance: A Closer Look
Morgan Stanley’s leading position by value is particularly noteworthy. The firm advised on deals totaling $128.3 billion, a figure that eclipses its competitors. This substantial sum indicates a strategic focus on large-cap transactions, often involving multinational corporations or significant private equity buyouts. The inclusion of 18 billion-dollar deals, three of which exceeded the $10 billion threshold, within Morgan Stanley’s portfolio is a key factor in its impressive valuation. These mega-deals, characterized by their complexity and significant financial implications, are typically the domain of the most experienced and well-resourced advisory firms.
Aurojyoti Bose, Lead Analyst at GlobalData, commented on Morgan Stanley’s performance, stating, "Morgan Stanley registered more than a five-fold year-on-year jump in the total value of deals advised by it and was the only adviser to surpass the $100 billion mark in total deal value in H1 2026. During this period, it advised on 18 billion-dollar deals that also included three mega deals valued more than $10 billion and involvement in these big-ticket deals helped Morgan Stanley register a massive jump in terms of value." This substantial year-on-year growth suggests a strategic acceleration in the firm’s M&A advisory services or a favorable market environment that allowed them to capitalize on opportunities.
Rothschild & Co’s Volume Leadership: The Engine of Activity
In contrast to Morgan Stanley’s focus on high-value transactions, Rothschild & Co’s dominance in deal volume, with 48 transactions, points to a different strategic approach. This volume indicates a high level of client engagement across a broader spectrum of deal sizes, from smaller strategic acquisitions to mid-market consolidations. Rothschild & Co’s consistent presence in the market, advising on a significant number of deals, suggests a robust client base and efficient deal execution capabilities. Their ability to manage a large pipeline of transactions speaks to a well-established operational framework and a deep understanding of the nuances of various European markets.
Bose further elaborated on Rothschild & Co’s dual success, noting, "Similarly, Rothschild & Co, apart from leading by volume, also occupied the ninth position by value." This dual presence in both volume and value rankings underscores Rothschild & Co’s balanced approach to M&A advisory, demonstrating both breadth of client service and the ability to engage in significant transactions.
Key Competitors in the M&A Advisory Arena
The league tables also highlight other significant players in the European M&A advisory space. In the value ranking, Goldman Sachs secured the second position with advised deals worth $97.8 billion, followed closely by Barclays at $88.2 billion. Bank of America rounded out the top five with $70.6 billion, and JPMorgan closed out the top tier with $65.2 billion. These institutions are known for their global reach, comprehensive financial services, and deep relationships with major corporations, making them consistent contenders in high-value M&A.
In terms of deal volume, Houlihan Lokey claimed the second spot with 45 transactions. The accounting and consulting giants, KPMG and PwC, shared the next position with 44 deals each, demonstrating their growing influence in M&A advisory, particularly in areas where due diligence and integration are paramount. Ernst & Young (EY) followed with 40 transactions, further cementing the significant role of professional services firms in the M&A ecosystem.
Analysis of Market Trends and Performance Drivers

The first half of 2026 appears to have been a period of robust activity in the European M&A market. Several factors likely contributed to this trend, including a more stable macroeconomic outlook compared to previous periods, potential shifts in corporate strategies driven by technological advancements, and ongoing consolidation within various industries. The strong performance of advisory firms like Morgan Stanley and Rothschild & Co suggests that businesses are actively seeking strategic opportunities for growth, market expansion, or operational efficiency through mergers and acquisitions.
Morgan Stanley’s significant year-on-year increase in advised deal value, as highlighted by Bose, could be attributed to several factors. The firm may have successfully leveraged its expertise in specific high-growth sectors such as technology, healthcare, or renewable energy, which have seen considerable M&A interest. Furthermore, their ability to secure and advise on mega-deals suggests a strong pipeline of mandates from large, established corporations and private equity funds actively deploying capital. The increasing complexity of cross-border transactions and the need for sophisticated financial engineering in large-scale deals also play to the strengths of global investment banks like Morgan Stanley.
Rothschild & Co’s consistent high volume of transactions indicates a strong advisory franchise that caters to a diverse client base. This could include a significant number of mid-market transactions, which often drive deal flow and require specialized expertise in navigating complex negotiation and regulatory landscapes. The firm’s long-standing reputation in M&A advisory, coupled with its deep understanding of European markets, likely contributes to its ability to maintain a high deal count.
Broader Implications for the European M&A Landscape
The performance of these leading advisors has broader implications for the European M&A landscape. The concentration of value in the hands of a few top-tier investment banks like Morgan Stanley underscores the importance of established relationships, global reach, and specialized expertise in securing and executing the largest deals. Simultaneously, the success of firms like Rothschild & Co in terms of volume suggests that the M&A market remains vibrant across different deal sizes, offering opportunities for a wider range of businesses to engage in strategic transactions.
The significant involvement of professional services firms such as KPMG, PwC, and EY in the volume rankings highlights the increasing integration of advisory services. These firms bring a unique blend of financial, operational, and strategic expertise, often focusing on the post-merger integration and operational efficiency aspects of M&A, which are critical for deal success.
The data also suggests a competitive environment where advisory firms are continuously innovating and adapting to market demands. The ability to provide end-to-end advisory services, from initial strategy formulation to deal execution and post-merger integration, is becoming increasingly crucial for success.

Looking Ahead: Future M&A Trends
As the second half of 2026 unfolds, several factors will continue to shape the European M&A landscape. Geopolitical developments, interest rate policies, inflation trends, and sector-specific dynamics will all play a role in influencing deal activity. Advisors will need to remain agile, possess deep market insights, and offer innovative solutions to navigate these evolving conditions. The ongoing digital transformation across industries will likely fuel further M&A activity as companies seek to acquire new technologies, enhance their digital capabilities, and consolidate their market positions in the digital economy. Furthermore, the increasing focus on environmental, social, and governance (ESG) factors is expected to drive M&A in sectors related to sustainability and renewable energy, presenting new opportunities for advisors specializing in these areas.
The performance of Morgan Stanley and Rothschild & Co in the first half of 2026 sets a strong precedent for the remainder of the year. Their respective successes in value and volume underscore the diverse strategies that can lead to market leadership in the complex and ever-evolving world of European M&A advisory. The continued robust activity suggests a confident market outlook, with businesses actively pursuing strategic growth and transformation through mergers and acquisitions.
