Notice of Merger of Group Companies 'Kartell Co., Ltd.' and 'Staff Co., Ltd.' and Post-Merger Company Name Change

DAIKEN Corporation (Kita-ku, Osaka City, President: Masanori Okuda) announces that, for the purpose of further business expansion, it has decided to merge its subsidiary 'Kartell Co., Ltd.' (hereinafter 'Kartell'), which handles the sales and installation of system storage, with Kartell's manufacturing subsidiary 'Staff Co., Ltd.' (a sub-subsidiary of our company, hereinafter 'Staff') on April 1, 2026, and to change the new company name after the merger to 'Ravio Co., Ltd.'.

**[Purpose of the Merger]**
Our group's Kartell, which handles the sales and installation of system storage for condominiums, collaborates with its manufacturing subsidiary Staff to conduct 'inclusive sales and installation', which means 'handling everything from the manufacturing of system storage to installation work internally'. In addition, their strengths lie in their stable product supply capability through their proprietary order management system that provides a one-stop service from order receipt, design, and manufacturing to installation, as well as their rapid and flexible response to custom orders. Currently, they hold approximately a 40%* share in system storage products for the Tokyo metropolitan area condominium market.
Under these circumstances, our company aims to further expand the scale of business by implementing capital investments of approximately 800 million yen in January this year to increase manufacturing capacity, in order to further strengthen the company's system storage business, armed with these unique strengths.

And now, as one of the measures to further strengthen the business, we will merge Kartell and Staff to construct an integrated manufacturing and sales system. By promoting management and productivity efficiency and providing higher quality and faster services, we will create a system that can demonstrate the company's strengths more than ever, aiming to expand our market share in the system storage market for condominiums in the Tokyo metropolitan area. In the future, by further developing the 'inclusive sales and installation' model, which is our strength of 'doing everything from manufacturing to construction internally', we will also consider business in new areas in addition to the Tokyo metropolitan area.
*In-house estimate.

**[About the post-merger 'Ravio Co., Ltd.']**
The new company name 'Ravio' is a combination of the Latin words 'Ratio', meaning 'reason and logic', and 'Avidus', meaning 'inquisitive mind and enthusiasm'. It embodies the desire to expand the scope of development more than ever by creating value while controlling the burning passion hidden inside and its energy with reason and logic.
In this merger, employees of both Kartell and Staff, which were separate companies for manufacturing and sales, took the lead in drafting the new company name and formulating the corporate philosophy so that they can work together as one team toward a new stage.
