December 17-19, Tokyo BS "SEMICON JAPAN 2025" Joint Exhibition by the JGC Group

Composite materials MMC enhance the performance of semiconductor manufacturing equipment - MMC components with high thermal conductivity, low thermal expansion, lightweight, high rigidity, and high precision improve equipment performance.

■MMC Adoption Effects Changed the cooling jacket from aluminum to composite material MMC (SA701) - Reduced thermal expansion difference with alumina ESC → Thermal expansion rate equivalent to alumina 7x10^-6/K - Improved thermal conductivity → 15% increase over aluminum (thermal conductivity: 160W/m·K) *Internal flow paths will be formed in the cooling jacket using MMC bonding technology. ■Development Information Currently developing SiC/Si-Al composite materials. Minimizing the thermal expansion difference with the next-generation "Aluminum Nitride ESC." ■High-Precision Processing New equipment has been added to high-precision processing technology, enabling the provision of larger MMC products with even higher precision. ○ Introduction of a laser interferometer (manufactured by Zygo) boasting one of the largest measurement ranges in Japan ○ Introduction of an ultra-high precision surface grinding machine (manufactured by Nagase Integrex) ◆ Exhibiting as the JGC Group at "SEMICON Japan 2025" ◆ Dates: December 17 (Wed) - 19 (Fri), 2025, 10:00-17:00 Venue: Tokyo Big Sight (West Hall 1) Booth: JGC Holdings (Booth No. W1165) We will showcase technology development for composite materials, ceramics, and the semiconductor, environmental, and energy sectors. We look forward to your visit.

We will be exhibiting jointly with the JGC Group at "SEMICON JAPAN 2025" held at Tokyo Big Sight. <JGC Group Exhibition Overview> Since its founding, the JGC Group has been involved in various fields, including EPC (Engineering, Procurement, and Construction) for plants and factories representing oil refining and natural gas, as well as diverse businesses such as the manufacturing of catalysts, inorganic materials, and fine ceramics components. In the semiconductor field, we contribute to the semiconductor industry in multiple ways, focusing on "design and construction of semiconductor-related factories," "components for semiconductor manufacturing equipment," and "materials for semiconductor materials." <JFC Exhibition Overview> In the Japan Fine Ceramics corner, we will introduce products and application examples related to semiconductors. ● Application examples of "metal-ceramic composite materials" for temperature-controlled wafer chucks and cooling jackets ● Thin-walled rib structures "SiC ceramics" for lightweight, high-rigidity stages ● Ceramic substrates and thin-film metallized substrates ● High-performance "silicon nitride substrates" for power semiconductors ● Transparent alumina, low dielectric loss alumina, Li-ion conductors, cells for SOFC/SOEC, pressure sensors for hydrogen environments We look forward to welcoming you at our booth.

Nitto Kohki will exhibit at the "30th Mechanical Components Technology Exhibition [Tokyo]" held at Makuhari Messe Hall 5 from July 9 (Wednesday) to July 11 (Friday). [Booth Number: Hall 5 31-32] At this exhibition, we will showcase a variety of products, including the electric suction hand "e-VEE" with a built-in pump that does not require compressed air, a cordless belt sander, the electric driver "Delvo" that can be mounted on robots, and the "Flow Monitor" that allows for easy visualization of the flow of cooling water in molds and other applications.

Nitto Kohki will hold the "2025 Attack Fair in Meiko" for two days from July 23 (Wednesday) to July 24 (Thursday), 2025, at the "Kowa Seminar Plaza 2F Training Room NO.12 (inside Kowa Sports Land)." The Attack Fair is an exhibition where you can actually "see, touch, and operate" Nitto Kohki's products. Additionally, there will be wonderful souvenirs for attendees and many fun activities planned. We look forward to welcoming everyone!

Nitto Kohki will hold the "2025 Attack Fair in Kurume" at the "Local Production Kurume General Exhibition Hall" for two days from February 13 (Thursday) to February 14 (Friday), 2025. The Attack Fair is an exhibition where you can actually "see, touch, and operate" Nitto Kohki's products. Additionally, there will be wonderful commemorative gifts for visitors and many fun activities prepared. We look forward to welcoming everyone!

[Speaker] EY Strategy and Consulting Co., Ltd. Transaction and Corporate Finance M&A Advisory Director Naoki Saito [Key Lecture Content] In recent years, the grid-scale battery business has garnered significant attention from practitioners, particularly in the renewable energy sector. However, it is also true that there are several challenges that remain to be addressed for further investment expansion. In this lecture, we will explain the finance environment, various markets utilized for revenue generation, and the diversifying business schemes that could influence the success or failure of investment expansion. We will also introduce the current challenges related to each theme, the efforts of market participants towards their resolution or improvement, and future outlooks. [Lecture Items] 1. Overview of the business surrounding grid-scale batteries (historical trends, etc.) 2. Diversifying business schemes 3. Current challenges hindering further investment expansion (finance methods, etc.) 4. Various initiatives towards problem-solving 5. Q&A / Business card exchange
