The Biggest Deals
of the Decade

Claire Williams | December 23, 2019

This past decade had a historic number of acquisitions, and we’ve witnessed some of the biggest players across all industries shake up their respective spaces. Months or even years of negotiation (and government approval) later, they’ve challenged competitors and created a sense of urgency to keep up in 2020.

With the new year right around the corner, and no sign of the market slowing down, we wanted to reflect on the last decade’s largest and most influential M&As. So without further-ado, here are the biggest mergers and acquisitions over the last 10 years!
