Mergers and acquisitions (M&A) allow companies to consolidate their organizations or assets. This process can involve anything from the purchase of specific assets to the consolidation of two companies.

The process can be complex, which is why merger consulting firms exist to advise on acquisitions or divestitures. CFOs and controllers work alongside these firms throughout the process to ensure a smooth transition.

The following companies represent the top M&A consulting firms in the United States (based on client and peer reviews) as well as the depth of their services.
