Instead, strategic buyers are using innovations as a means to achieve goals. Based on analyzing hundreds of recent deals, Mergers & Acquisitions has identified seven goals corporate dealmakers hope to accomplish through M&A transactions today: Integrate data with software; improve the customer experience and relationship; expand and improve distribution; process payments more efficiently; leverage tech trends, like autonomous vehicles; make manufacturing processes more efficient; and achieve better outcomes and efficiencies in healthcare. “Strategics have been really active,” says John Neuner, managing director, Harris Williams. “They are aggressive in pursuing the assets they want, as long as it fits within their strategy. Scale is critical to them, and they have to meet consumer demands by adding new capabilities.” Related: 7 reasons why smart companies Amazon, Nike, Target are doing M&A.
