This paper investigates how the investment horizon of a firm's institutional shareholders impacts the market for corporate control. We find that target firms with short-term shareholders are more likely to receive an acquisition bid but get lower premiums. In addition, we find that bidder firms with short-term shareholders experience significantly worse abnormal returns around the merger announcement, as well as higher long-run underperformance. These findings suggest that firms held by short-term investors have a weaker bargaining position in acquisitions. Weaker monitoring from short-term shareholders could allow managers to proceed with value-reducing acquisitions at the expense of shareholder returns.
