How many of today’s merger deals will look sparkly five years from now? The truth is, M&A activity typically destroys shareholder value. BCG’s research confirms that about two-thirds of all public takeovers wreck long-term value for the acquirer. The Achilles’ heel? It’s during postmerger integration where things often go awry.
