We present evidence that earnout agreements in acquisition contracts provide a substantial source of financing for acquirers. Acquirers in transactions with earnouts are significantly more likely to be financially constrained, face tighter credit market conditions, and use less debt and equity to fund acquisitions. Financially constrained acquirers also book lower fair values for the contingent claim. Earnout use is more likely in transactions that involve liquid sellers, and earnout bids garner higher transaction valuation multiples. Overall, the evidence suggests that earnouts are an economically material and increasingly common source of acquisition financing for acquirers with limited access to external capital.

We examine the impact of shared auditors, defined as audit firms that provide audit services to a target and its acquirer firm prior to an acquisition, on transaction outcomes. We find shared auditors are observed in nearly a quarter of all public acquisitions and targets are more likely to receive a bid from a firm that has the same auditor. Moreover, these shared auditor deals are associated with significantly lower deal premiums, lower target event returns, higher bidder event returns, and higher deal completion rates. These results are driven by bids in which targets and acquirers share the same practice office of an audit firm and in which the target is small. Overall, our evidence suggests that bidders benefit from sharing an auditor with the target. Our results are robust to controls for alternative explanations and for selection bias in the shared-auditor effect.
