1. ‌Explanation of operating results

   In the first quarter of fiscal year 2026, the Japanese economy showed signs of a gradual recovery due to improvements in the employment and income environment. However, the outlook remains uncertain due to factors such as the impact of U.S. trade policies and continued inflation.

   Amid these conditions, we have remained focused on our core management policies: enhancing the added value of its product business through an engineering-driven approach, transitioning from a contract-based business model to an engineering services business, and strengthening its management foundation to better respond to rapid changes and increasing market diversity. In alignment with its corporate mission-"Changing the World Through Coating, Cutting, and Polishing"-we continue to implement strategic initiatives to drive sustainable growth.

   As a result, the Group's performance for the three months ended June 30, 2025 showed sales of ¥2,693 million (up 5.0% year-on-year), operating profits of ¥84 million (down 70.7% year-on-year), ordinary profit of ¥19 million (down 94.8% year-on-year), and net loss attributable to owners of parent of ¥36 million (compared to a net profit of ¥405 million attributable to owners of parent in the same period last year).

   The financial performance of each business segment is outlined below.

   ・Product Business

   Net sales in the product business amounted to ¥2,487 million (up 14.4% year-on-year). Sales of high-tech products such as optical fiber and hard disks remained strong given the recovery trend in optical network infrastructure and general-purpose data investments in the United States. However, segment profit declined to ¥160 million (down 56.1% year-on-year) due to increases in selling, general and administrative expenses.

   ・OEM Business

   Net sales in the OEM business amounted to ¥206 million (down 47.3% year-on-year). While business from contract polishing remained steady, contract coating and slitting declined due to a focus on prototypes for mass production. As a result, segment loss was ¥76 million (compared to a segment loss of ¥79 million in the same period last year).
