The Synergy Solution

How Companies Win the Mergers & Acquisitions Game

Why—and how—business leaders need to rethink and reshape M&A deals to improve their success rate

Few other tools of corporate development and growth can change the value of a company—and its competitive future—as quickly and dramatically as a merger or acquisition. Yet, most companies fail to create shareholder value from these deals—and, in many cases, they destroy it and drag their organisations and customers through it in the process. This dynamic has been true since the M&A boom of the 1980s and continues today. It doesn’t have to be this way.

About the Book

The Synergy Solution will change how companies—managers, executives, and boards—think about and approach their M&A strategies and the performance promises they make to their shareholders. Beginning with a clear and well-accepted foundation of the economics of the M&A performance problem, Deloitte’s Mark Sirower and Jeff Weirens show acquirers how to develop and execute an M&A strategy—end-to-end—that both avoids the pitfalls that so many companies fall into and creates real, long-term shareholder value.
