Citi and UBS led the mergers and acquisitions (M&A) rankings for financial advisers during the first quarter (Q1) of 2025 in the Asia-Pacific region, according to the latest league table released by data and analytics firm GlobalData.

According to GlobalData’s Deals Database, Citi secured the top spot by deal value, advising on transactions worth a total of $6.7bn.

UBS led the rankings by deal volume, having advised on ten transactions during the quarter.

GlobalData lead analyst Aurojyoti Bose said: “UBS was the top adviser by both deal volume and value in Q1 2024 and managed to retain its leadership position in terms of volume in Q1 2025 but lost the top position in terms of value to Citi.

“There was a massive jump in the total value of deals advised by Citi during Q1 2025 compared to Q1 2024. Resultantly, it went ahead from occupying the 14th position by value in Q1 2024 to the top position in Q1 2025. Apart from leading by value in Q1 2025, Citi occupied the second position by volume and similarly, UBS, apart from leading by volume, also occupied the second position by value.”

UBS also ranked second in terms of deal value, with advisory roles in deals totalling $4.6bn.

Evercore followed with $4.1bn, while Gresham Advisory Partners and Deloitte advised on deals valued at $3.7bn and $2.3bn, respectively.

In terms of volume, Citi and Daiwa Securities Group each advised on six deals.

Deloitte and Mitsubishi UFJ Financial handled five transactions each, rounding out the top five by deal volume.

GlobalData’s league tables are based on the real-time tracking of thousands of company websites, advisory firm websites and other reliable sources available on 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.
