Financial data analytics company Refinitiv released its third-quarter league tables for law firm involvement in M&A for the first nine months of a record-breaking 2021, and while the rankings have shifted slightly from 2020, most of the names in the top 25 remain the same. 

By deal value, Sullivan & Cromwell tops Refinitiv’s list through the first nine months of the year with $535 billion in deals touched, constituting a 12.2% market share. The firm was third at this point in 2020.
