Notice Regarding Completion of Transition
to a Holding Company Structure

SOLIZE Corporation hereby announces that, based on the resolution passed at the General Meeting of Shareholders held on March 26, 2025, it has transitioned to a holding company structure through a company split and changed its corporate name to SOLIZE Holdings Corporation.

The three SOLIZE Split Preparatory Companies established for the transition to a holding company structure have also changed their corporate names to SOLIZE PARTNERS Corporation, SOLIZE Ureka Technology Corporation, and +81 Co., Ltd. as of July 1, 2025.
Following the transition, the listed company will be SOLIZE Holdings Corporation, the holding company of the Group (Securities Code: 5871).

Since its founding, SOLIZE Corporation has consistently pursued the digitalization of manufacturing and innovation in digital manufacturing through the use of digital technologies. With more than 2,000 engineers and consultants worldwide, the Company has built a service delivery structure specialized in high-end domains. Its core capabilities lie in leveraging expertise cultivated across a wide range of manufacturing sites to deliver results and in driving transformation based on visualization and quantification technologies that extend even to tacit knowledge (decision-making logic). Through these capabilities, the Company has provided value to customers, primarily major manufacturers.
To further expand its business, strengthen Group governance, and pursue enhanced corporate value, the Company has determined that it is desirable to establish a Group operating framework that further accelerates management while enabling agile and flexible decision-making. Accordingly, the Company has decided to transition to a holding company structure. Under the new structure, the holding company will specialize in Group management centered on the formulation of management strategy, reallocation of resources, strengthening of Group governance, strategic investments such as M&A, and corporate staff functions. Meanwhile, each operating company will respond swiftly to changes in its respective business environment, enabling the Group as a whole to evolve into a more adaptable and resilient management model.
