IMM PE to Acquire Ewha Diamond Industrial, Korea's No.1 and World's No.3 Diamond Tool Maker

50 Consecutive Years of Profitability
Strength in a Diversified Portfolio Spanning All Industries

IMM Private Equity (IMM PE) is set to acquire Ewha Diamond Industrial, the first diamond tool manufacturer in Korea. With its comprehensive product portfolio spanning construction, precision, semiconductors, and displays, as well as a global customer base, IMM PE aims to drive the company’s long-term growth.

According to the investment banking (IB) industry on May 13, IMM PE signed a share purchase agreement (SPA) with Ewha Diamond Industrial the previous day to acquire a 65% controlling stake for approximately 400 billion won.

Founded in 1975, Ewha Diamond Industrial was the first company in Korea to mass-produce diamond tools. Over the past 50 years, it has leveraged its accumulated technological expertise to achieve the top market share in Korea and rank among the top three globally in the industry.

Diamond tools are not simply consumables; they are core materials that determine the precision, yield, and productivity of customers’ manufacturing processes. Highly customized technical solutions are required for each customer’s specific process environment. Ewha Diamond Industrial counts leading companies such as Bosch, Hyundai Motor, Samsung Electronics, and TSMC among its clients.

Over the past 50 years, the company has continuously supplied high-value-added diamond tools tailored to the evolving needs of advanced industries, including construction and stone processing, automotive precision manufacturing, displays, and semiconductors. Building such a diversified product portfolio across multiple industries is considered a rare achievement.

Based on this foundation, Ewha Diamond Industrial has never recorded a loss since its establishment. With ten production sites worldwide and seven overseas sales subsidiaries, the company has built long-term business relationships with top companies in key regions and has a low dependency on any single client. Its ten largest customers account for less than 30% of sales, demonstrating robust resilience against fluctuations in individual industries and customer markets.

Leveraging its stable business foundation, Ewha Diamond Industrial is now benefiting from the recent expansion of investment in advanced manufacturing sectors such as semiconductors, healthcare, aerospace, and defense. Following the acquisition, IMM PE plans to further strengthen the company’s technological competitiveness and global customer base, actively supporting the expansion of its global production and sales infrastructure and increasing its market share in advanced industries.

In particular, the company plans to expand its market share among existing customers and explore new business opportunities through continued investment in research and development (R&D) and key personnel, as well as by reinforcing collaboration between its technical and sales teams.

An IMM PE representative stated, “We will implement a mid- to long-term growth strategy by leveraging our industrial network and diverse customer contacts within the Korean manufacturing sector,” adding, “We will continue to support the development of key talent and the strengthening of R&D capabilities, while respecting the company’s existing organization and technological culture.”
