We will jointly exhibit at "SEMICON JAPAN 2024" held at Tokyo Big Sight in December. <Overview of JGC Group's Exhibition> Since its founding, JGC Group has contributed to various fields, including EPC (Engineering, Procurement, and Construction) for plants and factories, primarily in oil refining and natural gas, as well as in diverse businesses such as the manufacturing of catalysts and fine ceramics. In the semiconductor field, we support the semiconductor industry from multiple angles, focusing on "design and construction of semiconductor-related factories," "components for semiconductor manufacturing equipment," and "materials for semiconductor materials." <JFC Exhibits> In the Japan Fine Ceramics corner, we will introduce products and application examples related to semiconductors. ● Guide beams made of metal-ceramic composite materials ● Large trays, stages, and pin chucks made of SiC ● Ceramic substrates and thin-film metallized substrates ● Solid electrolytes, Li-ion sensing films, SOFC/SOEC cells, pressure sensors for hydrogen environments <Exhibition Dates / Venue> Dates: December 13 (Wednesday) to 15 (Friday), 2024, 10:00 AM - 5:00 PM Venue: Tokyo Big Sight, East Hall 5, Booth No. 6032 Inside the JGC Holdings booth, Japan Fine Ceramics

Our company held a completion ceremony on October 2 for the new factory being constructed at our facility in Tohoku City, Miyagi Prefecture, aimed at mass production of silicon nitride insulating heat dissipation substrates. In pursuit of a low-carbon and decarbonized society, the power electronics sector is actively advancing the development and commercialization of power semiconductors, power semiconductor-equipped circuits, insulating heat dissipation substrates, and power modules, which are essential for energy-saving devices in HV/electric vehicles, high-speed rail, and industrial equipment. For improving power module performance, insulating heat dissipation substrates that can efficiently dissipate heat generated by power semiconductors and electronic devices are crucial. Our silicon nitride insulating heat dissipation substrates possess high thermal conductivity (80-90W), excellent mechanical properties, and insulation, earning high praise from automotive manufacturers and circuit board manufacturers as insulating heat dissipation substrates for power semiconductors used in hybrid and electric vehicles. This led us to decide on the investment for a mass production factory in November 2018, and it has now been completed. In addition to our plan to gradually increase production in line with market expansion, we also intend to realize the commercialization of insulating heat dissipation substrates with thermal conductivity increased to approximately 1.5 times the current level.

Our company has resolved at the board of directors meeting held on May 18, 2020, to conduct an absorption merger with our company as the surviving entity and our 100% subsidiary, Meito Giken Co., Ltd., as the dissolving entity, effective July 1, 2020. We hereby inform you as follows. 1. Purpose of the Merger Through this merger, we aim to further strengthen our integrated production system from raw material formulation to precision processing, and to provide attractive ceramic products and expand our business in the fields of engineering ceramics, electronic ceramics, metal ceramic composite materials, and precision processing of various ceramic components. 2. Summary of the Merger (1) Schedule: Date of board resolution and merger agreement signing: May 18, 2020; Merger date (effective date): July 1, 2020 (planned) (2) Method of Merger: This merger will be conducted as an absorption merger with our company as the surviving entity and Meito Giken Co., Ltd. as the dissolving entity.

Nihon Fine Ceramics Co., Ltd. (Headquarters: Sendai City) has recently established a new office in Tohoku City, Miyagi Prefecture, and completed the construction of a new factory. Since our founding in 1984, we have made fine ceramics, a new material, the cornerstone of our business, advancing research and development of ceramic products and continuously challenging ourselves to develop products that meet market demands, thereby aiming for continuous business expansion. As a result, we are currently at a significant turning point aiming for new growth accompanied by the expansion of our business. Considering the steady growth trends in the fine ceramics market, we have determined that it is necessary to enhance the competitiveness of our existing factories and to launch new businesses to respond to new demands in order to continue our growth. Therefore, we have established a new office in Tohoku City, Miyagi Prefecture, and constructed a new factory aimed at commencing operations in the first half of fiscal 2018, so that we can supply high-quality products to our customers even more efficiently. As a member of the JGC Group, we will strive for continuous growth to fulfill our mission: "We will gather our technologies and expertise on the world stage to create a rich future for people and the planet."

Thank you to everyone who visited us. We will be exhibiting at the "High-Performance Ceramics Exhibition" held at Tokyo Big Sight in April. At our booth, we will showcase: - A new product that further enhances the fracture resistance of silicon nitride ceramics and improves thermal conductivity. - A new material that does not bend like iron, utilizing the lightweight properties of aluminum, known as "composite materials of metals and ceramics." - "Ceramic substrates" characterized by thin film and film formation technology. If you have any concerns regarding equipment design, component design, thermal design, or anything else, please feel free to stop by our booth for a consultation. We look forward to seeing you.
