One of the more fertile areas of academic finance is explaining why M&A is so bad – mergers seem to be on average value destructive, so why do they keep happening? Are CEOs just stupid? Are bankers just evil and persuasive? Here’s one answer that may be worth considering, which is that it looks like a good idea to acquire a successful company run by a talented and dedicated founder-CEO, but then things go pear-shaped because that founder-CEO either (1) departs, voluntarily or otherwise, with his giant bags of loot, or (2) suddenly loses interest in running his or her company when it’s owned by someone else and that someone else is now the founder-CEO’s boss:
Bidder gains are lower for acquisitions that involve targets with a founder CEO than for acquisitions of targets without a founder. The difference in bidder gains between takeovers of targets with founder CEOs and those without a founder is statistically significant, economically material, and robust to several model specifications that include a wide variety of deal- and firm-level control variables, like form of payment, competition, relative size, as well as some characteristics of the target CEO, such as his cash flow and voting stakes, age, and tenure.
That’s from this paper by Nandu J. Nagarajan, Frederik P. Schlingemann, Marieke van der Poel and Mehmet F. Yalin. It doesn’t clear up the whole mystery – non-founder mergers have also destroyed some value here and there, though I guess statistically less so – but I found it kind of fun. Read more »
