RBC Capital Markets has emerged as the top mergers and acquisitions (M&A) financial adviser by value and volume in the oil and gas sector for the first three quarters of 2025 (Q1–Q3 2025), according to GlobalData. 

Analysis from GlobalData’s financial deals database shows that RBC Capital Markets advised on 16 transactions with a total value of $32.7bn. 

GlobalData lead analyst Aurojyoti Bose said: “RBC Capital Markets recorded year-on-year [YoY] improvement in deal volume but decline in deal value during Q1–Q3 2025. 

“Despite this, it rose to the top position in both categories, up from third by volume and seventh by value in Q1–Q3 2024. Notably, seven of the top ten advisers by value saw a YoY decline in total deal value during the same period.” 

Goldman Sachs ranked second in deal value, advising on transactions amounting to $25.2bn. BMO Capital Markets followed closely with $24.7bn. Although both Bank of America and Jefferies each advised on deals worth $22.8bn, Bank of America took the fourth spot because it was involved in fewer deals compared to Jefferies.  

In terms of deal volume, Evercore secured the second position with 11 transactions, followed by JP Morgan with ten deals. Moelis & Company and Piper Sandler both advised on nine transactions each. However, Moelis claimed the fourth position due to having a higher total deal value. 

GlobalData’s league tables are based on the real-time tracking of thousands of company websites, advisory firm websites and other reliable sources available in the secondary domain. A dedicated team of analysts monitors all these sources to gather in-depth details for each deal, including adviser names.  

To ensure further robustness to the data, the company also seeks submissions of deals from leading advisers.
