JP Morgan has emerged as leading financial adviser in terms of deal value within the power sector for the first half (H1) of 2025, while Rothschild has topped by volume, based on the latest financial advisers league table by GlobalData, a leading data and analytics company.

The insight from GlobalData’s deals database analysis revealed that JP Morgan advised on deals worth $44bn, securing its position at the top by value.

Rothschild took the lead in volume by advising on a total of ten transactions.

GlobalData lead analyst Aurojyoti Bose comments: “Rothschild & Co was the top adviser by volume in H1 2024 and managed to retain its leadership position by this metric in H1 2025 as well.

“Meanwhile, there was an improvement in JP Morgan’s ranking by value from the second position in H1 2024 to the top spot in H1 2025. This was due to involvement in big-ticket deals, which resulted in a massive jump in terms of value. During H1 2025, JP Morgan advised on five billion-dollar deals that also include three mega deals valued more than $10 billion.”

Despite topping by value, JP Morgan also claimed second place by volume with nine deals. They were closely followed by Evercore, Lazard and Carnegie, each having seven deals.
