Morgan Stanley and Rothschild & Co have emerged as the dominant forces in European mergers and acquisitions (M&A) advisory for the first nine months of 2026, according to the latest analysis from GlobalData’s financial deals database. The rankings highlight a dynamic period for the European M&A landscape, with both firms demonstrating exceptional performance in different yet crucial metrics – value and volume, respectively.
Morgan Stanley Dominates Deal Value
Morgan Stanley has secured the top position in terms of the total value of transactions advised upon, orchestrating deals worth an impressive $235.2 billion. This substantial figure underscores the firm’s strategic prowess and ability to facilitate large-scale, high-value transactions that shape key sectors of the European economy. The bank’s success is particularly notable given the competitive nature of the advisory market, indicating a strong client base and a deep understanding of complex financial engineering required for mega-deals.
The report reveals that Morgan Stanley was the sole advisor to surpass the $200 billion threshold in advised deal value. This achievement represents a significant year-on-year (YoY) surge, with the total value of deals advised by the firm experiencing more than a threefold increase compared to the same period in the previous year. This remarkable growth propelled Morgan Stanley from the second position in the prior year’s rankings to the coveted top spot. A key factor contributing to this impressive valuation was Morgan Stanley’s involvement in a significant number of mega-deals, including six transactions each valued at over $10 billion. This demonstrates their capacity to attract and execute the most substantial and impactful M&A opportunities.
Rothschild & Co Leads in Deal Volume
In a testament to its extensive network and consistent deal origination capabilities, Rothschild & Co has claimed the leading position in terms of the sheer number of transactions advised upon. The firm participated in a remarkable 80 deals during the Q1-Q3 2026 period. This achievement marks a continuation of Rothschild & Co’s dominance in volume-based rankings, having also held the top spot in the same metric for Q1-Q3 2025.
While Rothschild & Co maintained its leadership in volume, the analysis notes a slight year-on-year decrease in the total number of deals advised. Despite this, the firm’s ability to consistently close a high volume of transactions highlights its enduring strength and widespread reach across the European M&A market. The firm faced robust competition, with PwC securing a close second place in the volume rankings, advising on 79 deals. This proximity underscores the intense competition among advisory firms striving to capture market share through sheer deal execution.
Key Players and Market Dynamics
The GlobalData rankings provide a comprehensive overview of the advisory landscape, identifying other significant contributors to the European M&A market.
In the value-driven rankings, Barclays emerged as a strong contender, securing the second position with transactions totaling $132.2 billion. This performance indicates Barclays’ significant influence in facilitating substantial corporate transactions. Goldman Sachs followed closely in third place, advising on deals worth $116.8 billion, demonstrating its continued prominence in high-value M&A. JPMorgan secured the fourth spot with $106.2 billion, and Evercore rounded out the top five with $103.7 billion, highlighting a concentrated group of major global players dominating the high-value segment.
The volume rankings also reveal a competitive field beyond the top two. Houlihan Lokey secured third place with 77 deals, demonstrating its strong execution capabilities. Ernst & Young followed with 70 deals, and KPMG with 69 deals, showcasing the significant presence of the Big Four accounting firms in M&A advisory, particularly in terms of deal volume.
Analysis and Expert Commentary
Aurojyoti Bose, Lead Analyst at GlobalData, provided insights into the prevailing market trends and the performance of the leading advisors. "Rothschild & Co was the top adviser by volume during Q1-Q3 2025 and managed to retain its leadership position by this metric during Q1-Q3 2026 as well, despite a year-on-year (YoY) drop in the total number of deals advised by it," Bose stated. "However, it faced close competition from PwC, which occupied the second spot by volume with 79 deals."
Bose further elaborated on Morgan Stanley’s exceptional performance: "Meanwhile, Morgan Stanley was the only adviser with more than $200bn in total value of deals advised. Subsequently, it registered more than a three-fold jump YoY in the total value of deals advised, and its ranking improved from second to the top position. During Q1-Q3 2026, Morgan Stanley advised on $37bn deals that also included six mega deals valued more than $10bn."
The analysis by GlobalData highlights a bifurcated market dynamic. While firms like Rothschild & Co thrive on a high volume of transactions, often indicative of a broad client base and expertise across various deal sizes and sectors, institutions like Morgan Stanley excel in commanding the largest and most complex deals, which require deep financial engineering and strategic advisory capabilities.

Broader Implications for the European M&A Landscape
The Q1-Q3 2026 European M&A advisory rankings offer several key takeaways for the broader financial ecosystem. The continued dominance of established global investment banks like Morgan Stanley and Rothschild & Co suggests that experience, established networks, and a proven track record remain critical differentiators in securing high-profile mandates.
Morgan Stanley’s significant surge in advised deal value indicates a potential uptick in large-scale corporate restructuring, strategic acquisitions, or private equity activity within Europe. The firm’s ability to facilitate six mega-deals above $10 billion points towards an environment where significant capital is being deployed for transformative transactions. This could signal increased confidence among institutional investors and corporate leaders in the European economic outlook, driving ambitious growth strategies.
Rothschild & Co’s sustained leadership in volume, despite a minor dip, underscores the ongoing activity in the mid-market and smaller deal segments. This segment often reflects the underlying health of various industries and the propensity of companies to pursue strategic partnerships, bolt-on acquisitions, or divestitures. The close competition from PwC in volume suggests a growing challenge from professional services firms, which are increasingly expanding their M&A advisory capabilities.
The performance of other major banks like Barclays, Goldman Sachs, and JPMorgan in the value rankings reinforces their positions as key players capable of handling significant transaction volumes. Their consistent presence in the top tiers indicates a stable, albeit competitive, market structure for high-value M&A.
Looking ahead, the trends observed in the first nine months of 2026 suggest that the European M&A market is characterized by both strategic consolidation at the top end and a steady flow of activity across a wider spectrum of deal sizes. The advisory firms that can demonstrate both deep sector expertise and robust execution capabilities are best positioned to capitalize on the evolving opportunities within this dynamic market. The continued focus on data integrity and comprehensive tracking by entities like GlobalData will remain crucial for providing accurate insights into the complex and ever-changing world of corporate finance.
