Announcement of Establishment of a Subsidiary by Company Split


 Rakuten Group, Inc. (hereafter “the Company”) announces that Rakuten Mobile, Inc. (hereafter “Rakuten Mobile”), a wholly-owned subsidiary of the Company, has completed the succession of rights and obligations of "Rakuten Symphony" business (hereafter “the Business”) to Rakuten Symphony, Inc. (hereafter “Rakuten Symphony”) which is a wholly-owned subsidiary of Rakuten Mobile, established through an incorporation-type company split, as described below.
 Since this incorporation-type company split corresponds to an incorporation-type company split involving only a wholly-owned subsidiary of the Company, the disclosure of certain items and details has been omitted from this announcement.


1. Purpose of the company split

 The business aims to provide a future-proof, cost-effective, communication cloud platform for carriers, businesses and government agencies around the world by consolidating the products and services which are related to cloud-native, open RAN-based mobile networks including Rakuten Communications Platform (hereafter "RCP").
 In addition, as announced in "1&1 and Rakuten agree far-reaching partnership to build Europe's first fully virtualized mobile network based on new OpenRAN technology” on August 4, 2021,  1&1 has agreed to comprehensively adopt RCP. The business has been steadily accumulating its achievements.
 As announced on September 30, 2021 in "Announcement Regarding Incorporation, etc, of Rakuten Symphony”, through the incorporation, accountability (duties) will be clarified, flexible decision-making and business execution will be possible, and products, services, and solutions for telecommunications carriers will be consolidated across the board. We will be ready to provide 4G and 5G infrastructure and platform solutions to the global market.
