Do mergers and acquisitions create value for shareholders? As global competition increases, companies buy other companies, and owners demand more top-line growth to increase shareholder value. Some business owners believe that acquisitions transform their businesses and can give them a competitive advantage through new value propositions and focused business strategies. An M&A event: value creation or destruction? It comes down to aspects the acquirer can control and market conditions that can rapidly change a good deal into a financial or operational challenge. The acquirer’s shareholders must understand the acquirer's integration capabilities and where the potential for value creation lies. From the target’s perspective, it is about valuation and the probability of closing. Yet over two-thirds of all mergers and acquisitions (M&A) fail to produce the projected synergies and financial numbers. Why is that? A survey early this year included six hundred global senior corporate executives from across industries and geographies. They asked executives about their experiences with value creation through M&A. Here are the highlights of the findings: Ninety-two percent of acquirers said they had a value creation plan in place for their last deal, but only 61 percent of buyers believed their last acquisition created value. Fifty-three percent underperformed vis-à-vis their industry peers, on average, over the 24 months following completion of their last deal based on total shareholder return (TSR). From a seller’s perspective, forty-two percent of divestors likewise said their last sales generated value, relative to the value that business would have created had it not been sold. Around thirteen percent said their last divestment generated significant value, and thirty-five percent said their last deal lost value.
