Jones Day and Kirkland & Ellis have emerged as the leading mergers and acquisitions (M&A) legal advisers by value and volume in the power sector for 2023, according to GlobalData’s league table.

The deals database of GlobalData, a leading data and analytics company that is the parent of Power Technology, shows Jones Day securing the top position by value, having advised on deals worth $13.5bn.

Kirkland & Ellis, with its advisory services on deals valued at $8.8bn, claimed the second spot by value and led the volume chart with 34 deals.

GlobalData lead analyst Aurojyoti Bose said: “Jones Day was the clear winner in terms of value as it was the only firm to surpass $10bn in total deal value during 2023.

“The adviser witnessed a 72% jump in total value of deals advised by it in 2023 compared with 2022, which resulted in a jump from 24th position by value in 2022 to the top position by this metric in 2023.

“Meanwhile, Kirkland & Ellis, which was the top adviser by volume in 2022, also retained its leadership position by this metric in 2023 despite experiencing a decline in the number of deals advised.”
