Prior to its major business integration and merger with Minebea Company to form MinebeaMitsumi, Mitsumi Electric Co., Ltd. primarily focused on organic growth, joint ventures, and strategic technological partnerships within the electronics sector rather than executing massive external corporate takeovers. Following the structural combination, the resulting parent entity has actively pursued and completed numerous strategic acquisitions, absorbing companies like U-Shin, ABLIC, and Hitachi Power Semiconductor Device.
