This paper investigates how and through what mechanisms a knowledge-intensive acquired firm influences customer recapturing following a cross-border M&A. This is studied in the setting of a Chinese firm’s acquisition of a Finnish, knowledge-intensive firm in the maritime industry. The paper indicates the following mechanisms for customer recapturing in the post-M&A integration process: investments, human resource management, information about M&A, and interest in the customer.
