March 17, 2026

OSG held its 113th Annual General Meeting of Shareholders on February 20 at a hotel in Toyohashi, Aichi Prefecture. Sales revenue for the fiscal year ended November 2025 reached a record high of JPY 160.62 billion, up 3.3% year-on-year (YoY). Operating profit increased 7.7% YoY to JPY 20.33 billion, and net profit rose 6.7% YoY to JPY 14.33 billion. The impact of U.S. tariff increases was less severe than anticipated, while robust orders for artificial intelligence (AI)-related applications provided support. The overseas sales ratio reached a record 68.2%, led by Asian regions including China, Thailand, and India.

Chairman and CEO Norio Ishikawa, who presided over the meeting, stated: “We want to strengthen our product lineup of diamond tools required for precision micro-machining fields such as semiconductors and medical applications, as well as lens processing.” While maintaining the competitiveness of taps, where the company holds a high global market share, OSG aims to increase adoption not only in its strong automotive sector but also in aerospace, defense, semiconductors, and medical fields. For the fiscal year ending November 2026, the company targets sales revenue of JPY 165 billion and operating profit of JPY 22 billion.
