This paper examines the determinants of the choice of financial advisors and their impact on the announcement effects of US acquirers in cross-border M&As. Two hypotheses are tested: one pertains to the certification role of financial advisors, and the other relates to advisors' experience in target countries. Evidence supports the certification hypothesis in the selection of advisors, particularly in all-cash paid transactions where acquirers assume the entire risk of not realizing the expected synergy value. We also observe significantly more favorable shareholder reactions to the choice of US-domiciled advisors and foreign-domiciled advisors actively doing business in US markets. The fact that this positive reaction exists when the chosen US advisors do not have significant experience in the target country suggests how much US acquirers and shareholders value the certification role of financial advisors in cross-border M&As.
