1. Background and Purpose of Making Fieldtech a Subsidiary
Under the corporate philosophy of "Bringing peace of mind to society, growth to companies, and happy work styles to people through digital technology," our corporate group has anticipated the "AI Agent Era" where AI makes autonomous judgments and actions, and has declared its evolution into an "AI Guardian from Japan" that protects the trust and safety of AI.
The Company anticipates that network communication traffic will explode due to the widespread adoption of "AI Agents" operating autonomously 24 hours a day, 365 days a year on behalf of humans. Consequently, we believe that the reconstruction and strengthening of communication infrastructure will become the lifeline of the AI era, creating long-term demand on a scale exceeding the 5G transition period.
Fieldtech has continued to do business as a construction company with major telecommunications carriers (such as the SoftBank Group) that have had strict requirement standards for 30 years, possessing advanced technological capabilities and project management skills that oversee processes, quality, safety, and upstream/downstream operations.
By welcoming Fieldtech to the group, the Company will create the following synergies, striving to achieve the group's medium-term management plan and enhance corporate value accordingly.
2. Synergies from this Transaction
(1) Expansion of Fieldtech's Business Partners
Through the network held by the Company's directors and advisors, including ITOCHU Techno-Solutions Corporation with which the Company has a capital and business alliance, we will expand Fieldtech's transactions with major companies in the communication infrastructure construction industry, leading to business expansion.
(2) In-house Consolidation of Installation and Configuration Work for the Company's Security Products/Commodities
By having Fieldtech take charge of the installation and configuration work at end-user sites for the security products and commodities handled by the Company, we will reduce outsourced projects and contribute to the expansion of group profits.
(3) Group-wide Recruitment of Young Talent and Human Resource Development
The Company group has set the "Construction of an IT Engineer Group" as one of its strategic themes. As an IT human resources company, it has one communication/network-related company, three development-related companies, and one AI engineer company. With Fieldtech joining the group, there will be two communication/network-related companies, creating an environment where we can propose various careers to young talent as a unified group. Additionally, through the integrated support of recruitment strategies and training processes by the two recruitment support companies within our group, we will expand the group's recruitment capabilities.
