The Success of Acquisitions: Evidence from Divestitures.

This paper studies a sample of large acquisitions completed between 1971 and 1982. By the end of 1989, acquirers have divested almost 44 percent of the target companies. The authors characterize the ex post success of the divested acquisitions and consider 34 percent to 50 percent of classified divestitures as unsuccessful. Acquirer returns and total (acquirer and target) returns at the acquisition announcement are significantly lower for unsuccessful divestitures than for successful divestitures and acquisitions not divested. Although diversifying acquisitions are almost four times more likely to be divested than related acquisitions, they do not find strong evidence that diversifying acquisitions are less successful than related ones.
