Background and Objectives of the Alliance

Under its 'Medium-Term Management Plan 2028,' which concludes in the fiscal year ending October 2028, Tobira Systems has set a target of achieving ¥6 billion in sales and ¥1.7 billion in operating profit for that fiscal year. One of the key initiatives to achieve this goal is the acceleration of 'Tobira Phone Cloud' sales, and the company is actively working toward business growth.

'Tobira Phone Cloud' is a cloud PBX service designed to support the efficiency and digital transformation (DX) of corporate telephony operations. Leveraging its proprietary features based on spam information databases, as well as expertise and product development capabilities in corporate telephony DX, Tobira Systems is working to enhance the sophistication and usability of voice communication infrastructure for enterprises.

Prodilight provides corporate telephone systems and voice communication services centered on its cloud PBX 'INNOVERA,' supporting corporate telephony DX initiatives. The company possesses expertise in cloud PBX and corporate voice communication services, a customer base, sales partners, and know-how in sales and implementation support.

The cloud PBX market, in which both companies operate, is expected to expand steadily in the medium to long term, driven by the IP- and cloud-based transformation of fixed-line infrastructure, growing corporate demand for DX, diversified workstyles, and increasing needs for operational efficiency. At the same time, as businesses transition from traditional business phones and PBX systems to cloud PBX, the importance of proper operational design during implementation, migration support from existing phone environments, customized functionality aligned with customer workflows, integration with AI features and external systems, and post-implementation support is increasing. As a result, competition for customer acquisition is intensifying.

Under these market conditions, Tobira Systems believes that to strengthen competitiveness in the cloud PBX market and improve convenience and efficiency for corporate customers, it is essential not only to enhance product functionality and sales channels but also to continuously increase value through service integration and joint development, leveraging both companies' expertise and customer bases.

This capital and business alliance aims to enhance both companies' competitiveness by mutually leveraging their respective strengths in cloud PBX technology, development capabilities, customer bases, sales channels, and sales and implementation support know-how, thereby expanding market share in the cloud PBX market. Furthermore, Tobira Systems believes that in addition to operational collaboration, establishing a capital relationship will effectively strengthen the long-term partnership between the two companies.

Going forward, both companies will contribute to solving corporate customers' telephony challenges through the provision of cloud PBX services, mutual utilization of sales channels, enhanced implementation support, service integration, and continuous service improvements based on customer needs, while aiming to expand market share in the cloud PBX market and enhance both companies' corporate value.
