1. Reason for the acquisition of shares
In light of rapid changes in the business environment surrounding the MIRAIT ONE Group (the "Group"), we have been focusing on the transformation of our business structure by concentrating our management resources in growth areas that we have positioned as "MIRAI Domains," such as "city and village development /corporate DX and GX" and "software business," as a new growth strategy under the "MIRAIT ONE Group Vision 2030" announced in May 2022.

To expand the "MIRAI Domains," we aim to develop our business under a "full-value" model by concurrently promoting "horizontal integration," which combines various engineering fields such as communications, electricity, and ICT, and "vertical integration," which provides highly added value through full-phased service offerings from planning and proposal to construction, maintenance, and operation.

Through this acquisition of the shares, the Group will work to further expand the cloud management field of its solutions business and provide services from planning and proposal to maintenance and operation under a full-value model by integrating the cloud technology and operation and monitoring skills of Y2S Corporation with the Group's resources, with the aim to further increase added value.
