II. BUSINESS CONTENT 1. Business Overview The company was founded in 2000 as a semiconductor equipment manufacturer. It provides equipment that forms thin films on semiconductor wafers via chemical reactions during the front-end wafer processing stage. Key products under development or completed in the semiconductor equipment segment include BlueJay™ (a Single Thermal LPCVD - Low Pressure Chemical Vapor Deposition System), which deposits particles formed by chemical reactions between reactant gases onto wafer surfaces to form insulating or conductive thin films. Additionally, the company developed Albatross™ (Plasma Treatment System) and supplied it to domestic device makers, as well as Harrier™ (Batch type ALD - Atomic Layer Deposition System). In the semiconductor materials segment, the company focuses on increasing sales of precursors used for high-k material thin film deposition for DRAM capacitors to domestic semiconductor device makers. Q1 2026 consolidated financial results: Revenue KRW 101,874 million, Operating Profit KRW 18,834 million. Breakdown: Semiconductor equipment segment KRW 81,776 million; Semiconductor industrial gases & materials segment KRW 3,712 million; Other (merchandise sales etc.) KRW 16,386 million. Exports totaled KRW 37,132 million, representing 36.45% of total revenue. The company expects to sustain growth through technology competitiveness and a focus strategy on high-value-added and differentiated products, with continued mid-to-long-term efforts to diversify customers and expand product lineup. 2. Key Products and Services A. Current Status of Key Products (Unit: KRW million) Segment | Sales Type | Item | Specific Use | Major Brands | Q1 of 27th FY Revenue (Ratio) Semiconductor Equipment | Product | LPCVD/Plasma/ALD | Semiconductor front-end equipment: deposits specific films (oxide, insulating, etc.) on wafers | BlueJay, Albatross, QXP | 81,776 (80.3%) Semiconductor Industrial Gases / Materials | Product | Precursor | Chemicals used in thin film deposition during semiconductor front-end process | SP | 3,712 (3.6%) Other | Other | Raw materials | Raw materials, etc. | - | 16,386 (16.1%) Total: 101,874 (100%) The company's core focus area, under development or completed and applied to semiconductor wafer manufacturing, is chemical vapor deposition (CVD) technology. CVD is a critical semiconductor manufacturing process in which particles formed through chemical reactions between reactant gases are deposited onto the wafer surface to form insulating or conductive films. The company supplies equipment that forms thin films on semiconductor wafers via chemical reactions during front-end wafer processing. Front-end semiconductor materials refer to chemical materials related to the manufacturing process (lithography - deposition - etching). Among these, precursors used in the deposition process are the company's core focus, with various compounds used in manufacturing metal gates, capacitors, and electrode wiring. Precursors are introduced into reactors for CVD, ALD, etc., where they trigger chemical reactions to deposit thin films of the desired composition onto wafers. Their properties are so critical that they constrain the performance and design of deposition equipment, and their importance is increasing. The company has established integrated production capabilities from precursor material design through synthesis, purification, and distribution. B. Price Trends of Key Products The company's products take various forms depending on customer requirements, and prices vary based on the number of chambers attached. Because process characteristics and the number and types of chambers differ across generations, prices are not consistent across products. 3. Raw Materials and Production Facilities A. Status of Key Raw Materials (As of March 31, 2026, Unit: KRW million) Segment | Purchase Type | Item | Major Suppliers | Specific Use | Purchase Amount | Ratio Semiconductor Equipment | Raw Material | Platform | Brooks, etc. | Wafer transfer device | 5,923 | 9.1% | | Heater | Inabata, etc. | Chamber accessories (maintains wafer at high temperature) | 5,146 | 7.9% | | Other | - | Semiconductor equipment manufacturing parts | 53,858 | 83.0% Total: 64,927 | 100% * The above represents Q1 2026 purchases of major raw materials on a K-IFRS separate basis. Raw materials used in the semiconductor equipment production process consist primarily of platforms, heaters, and other materials. The company's semiconductor equipment is produced 100% on a made-to-order basis, resulting in long lead times and raw material purchases driven by customer orders. Equipment specifications vary by order and customer requirements. Core raw material prices fluctuate based on order conditions and supply/demand circumstances at the time of purchase. B.
