CMTX Submits Securities Registration Statement, Initiates KOSDAQ Listing Process

CMTX, a company specializing in the manufacturing of silicon (Si) parts for semiconductor etching processes, announced on October 2 that it has submitted a securities registration statement to the Financial Services Commission, officially initiating its KOSDAQ listing process. The company is led by co-CEOs Park Sunghoon and Park Jonghwa.

For this listing, CMTX will offer 1 million shares, all as new shares. The desired offering price ranges from 51,000 to 60,500 KRW per share, resulting in a total offering amount of between 51 billion and 60.5 billion KRW. The demand forecast will be conducted over five days from October 29 to November 4, with general subscriptions taking place on November 10 and 11. The company aims to be listed on KOSDAQ within the year. Mirae Asset Securities is serving as the lead underwriter.

Since its establishment in 2013, CMTX has expanded its business from ceramic and sapphire parts for semiconductor etching processes to core consumable silicon components such as silicon rings and electrodes. CMTX is the only company in Korea with a fully vertically integrated system that independently handles every step from silicon ingot production to final parts manufacturing. This structure has enabled the company to secure cost competitiveness and consistent quality. Through its subsidiary Cellic, CMTX produces up to 200 tons of monocrystalline and polycrystalline silicon ingots annually, achieving material localization.

Recently, the global semiconductor industry has seen a rapid shift away from the traditional structure of sourcing parts through equipment manufacturers, moving instead toward direct transactions with parts suppliers in the aftermarket. This trend allows major fabs to reduce the margin burden from equipment manufacturers while directly acquiring process-specific data to enhance engineering capabilities and process reliability.

Amid these changes, CMTX is recognized for its price competitiveness and advanced process response capabilities, thanks to its unique material localization and full-process capabilities in Korea. Furthermore, the company is able to provide detailed process data and customized technical consultations, earning a reputation as a differentiated and trusted partner for global fabs.

This competitive edge has already been demonstrated through successful collaborations with global clients. CMTX maintains first-tier supplier relationships with major domestic fab customers and, notably, is the first and only Korean company selected as a first-tier supplier for TSMC, supplying products for TSMC's 3nm to 2nm advanced process mass production lines.

Collaboration with semiconductor fabs is characterized by extremely high entry barriers, as partnerships typically lead to long-term business relationships once a supplier is validated. Therefore, cooperation with global advanced process customers such as TSMC not only serves as evidence of CMTX's technical expertise and reliability but also provides a stable foundation for future growth, supporting the company's long-term corporate value and growth potential. Based on these achievements, CMTX is rapidly expanding its presence within the global supply chain, conducting business with more than 20 major fabs worldwide.

In addition to its success with global customers, CMTX is also driving innovation in the ESG sector. The company has developed the world's first silicon parts recycling technology, which enables the purification of used parts to a high degree of purity, achieving performance equivalent to new products. This not only reduces costs compared to conventional materials but also generates approximately 135 million KRW in annual carbon credits, establishing an ESG-friendly business model. Currently, CMTX is conducting joint process evaluations with major domestic fabs and has passed Micron's certification test for recycled parts processes, paving the way for global market expansion.

This exceptional competitiveness has translated into rapid financial growth. In the first half of 2025, CMTX recorded sales of 77.3 billion KRW, a 93% increase from 40 billion KRW in the same period of the previous year. Operating profit reached 26.3 billion KRW, up 417% from 5 billion KRW a year earlier. The operating margin during this period was 34%, representing one of the highest levels of profitability in the industry. This growth is not a short-term phenomenon; over the past three years (2022-2024), the company achieved a compound annual growth rate of 142% in consolidated sales, demonstrating its long-term growth potential.

With the capital raised from this listing, CMTX plans to accelerate its growth strategies. The company will first expand its second factory in Gumi (M Campus), increasing production capacity by more than five times compared to 2023 to meet rising global fab demand. In addition, CMTX will enhance its material recycling technology, conduct R&D for new process responses, and commercialize new materials, thereby strengthening its high-value-added product lineup, expanding its global customer base, and further solidifying its long-term growth drivers.

Park Sunghoon, CEO of CMTX, stated, "We have demonstrated our value in the global semiconductor parts market based on the cost competitiveness and quality superiority achieved through full-process vertical integration. With this listing as a catalyst, we will accelerate research and development, expand production capacity, and intensify our global market strategies to become a leading global company in semiconductor materials and parts."
