This paper focuses on financial (bank) firms’ internationalization. We utilize and integrate literature from international dynamic marketing capability with business network theory. Financial firms in their internationalization quest need to offer competitive services to local customers but local regulations, lack of knowledge of local culture, and language, and other business-level obstacles such as the lack of knowledge about customers and the competitive environment of the target market hamper the path to be able to do so. Therefore, this paper aims to explore how a firm develops international dynamic marketing capability and penetrates foreign markets and networks by absorbing local capabilities into their organization. Based on qualitative case study research. We found that the focal firm already has different marketing capabilities but utilizing their business networks also can absorb local capabilities that enhance their international dynamic marketing capability and penetrate foreign networks.
