How do nancial frictions shape the set of acquirers, how much they acquire, and how long they keep ownership? To address these questions, we develop a tractable model of M&As whereby acquirers and targets emerge endogenously due to di erences in liquidity. Financial crises lead to selection e ects among acquirers that result in larger acquired stakes and more persistent ownership. We present evidence consistent with the predictions of the model in a dataset of domestic and cross-border M&As from emerging markets. Financially constrained domestic rms in crisis-hit countries acquire 11-15% more ownership. The survival rate of these acquisitions is 19-24% higher.
