Simpson Thacher & Bartlett closed out a record-breaking year for M&A with three separate deals for corporate clients during the high point of the holiday season.

The firm advised an affiliate of longtime private equity client The Blackstone Group on its $1.9 billion buy of 49 U.S. shopping centers owned by Toronto-based RioCan Real Estate Investment Trust, which received counsel from Canada’s Goodmans on the transaction. Simpson Thacher also teamed up with Italian firm Legance in advising London-based buyout firm Apax Partners on its $1.14 billion sale of Rhiag-Inter Auto Parts Italia to Chicago-based LKQ Corp., advised by K&L Gates.
