Top Advisers by Value and Volume
Cravath Swaine & Moore and CMS emerged as the top mergers and acquisitions (M&A) legal advisers in Europe for Q1 2021 by value and volume, respectively.
Cravath Swaine & Moore advised on eight deals valued at $55.4bn, which was the highest value among all the advisers. CMS led the volume chart, having advised on 64 deals worth $4.4bn.
GlobalData lead analyst Aurojyoti Bose said: “CMS was the only adviser that managed to advise on more than 50 deals during Q1 2021, outpacing its peers by a great margin in terms of volume. However, it lagged behind in terms of deal value due to involvement in low-value transactions and did not even feature among the top 10 advisors by value.
“Meanwhile, Cravath Swaine & Moore, which advised on just eight deals, managed to top the list by value due to its involvement in big ticket deals. While the average deal size of transactions advised by Cravath Swaine & Moore stood at US$6.9bn, it was just $69m for CMS.”
