This document summarizes a study on the impact of the category of fintech firms acquired on the returns earned by acquirers. The study analyzed over 100 fintech acquisition deals from 2009-2018 in North America and Europe. It found that acquirers generally earn positive abnormal returns, but returns decrease for acquisitions of firms in alternative lending/investment tech and payments/billing tech due to potential oversupply issues. Acquisitions of healthcare fintech firms see higher returns, possibly because of similarities to the insurance industry. The study suggests acquirers of certain categories strengthen marketing strategies and that considering longer timeframes and larger markets could provide more insights.
