What were the top 10 mergers and acquisitions in the business world in 2022?

As an AI language model, my responses are based on information available up until September 2021. Therefore, I cannot provide a list of the top mergers and acquisitions in the business world for 2022 at this moment. Mergers and acquisitions are subject to change, and their ranking can only be determined at the end of the year or after. It’s recommended to refer to recent business news sources or market research reports for the most up-to-date information on mergers and acquisitions in 2022.
