Group 1 - In Q3 2025, a notable change occurred in the shareholder list of a domestic photoresist company, with Goldman Sachs, JPMorgan Chase, UBS, and Morgan Stanley collectively purchasing nearly 5 million shares despite the company's stock price plummeting from 30 yuan to 4.4 yuan, marking a 1700% drop in net profit in the mid-2025 report [1][3] - The foreign investment strategy reflects a significant bet on domestic substitution, as these institutions entered the top ten shareholders for the first time, with acquisition costs concentrated in the 6-7 yuan range, resulting in over 30% floating profit by early December [3][9] - The company has a total market value of 4.8 billion yuan, with its photoresist business accounting for 62% of revenue and a gross margin of 32%, despite an overall decline in performance [3] Group 2 - Photoresist is a critical consumable in semiconductor manufacturing, with the global market dominated by Japanese and American companies, which hold 87% of the market share, particularly in high-end sectors where domestic production is less than 1% for ArF photoresists and completely reliant on imports for EUV photoresists [5] - The Chinese semiconductor photoresist market is projected to reach 5.63 billion yuan in 2024, reflecting a 42.25% year-on-year growth, driven by increased demand from wafer fabs like SMIC and Huahong Group adopting domestic materials [5] - Domestic photoresist companies are advancing in production capabilities, with firms like Nanda Optoelectronics and Tongcheng New Materials achieving mass production of ArF/KrF photoresists, while others focus on specific segments like PCB photoresists [7] Group 3 - Foreign investors are betting on photoresist companies based on three clear logics: high certainty of domestic substitution due to Japanese export controls, low historical valuation with a price-to-book ratio of 1.2 compared to the industry average of 3.54, and the potential for significant performance improvement in small-cap stocks upon technological breakthroughs [9] - Similar cases have emerged where companies with traditional chemical businesses, like Xilong Science, have seen foreign investment despite poor performance, indicating a trend of foreign capital seeking opportunities in the photoresist sector [9]

Core Viewpoint - SK Hynix is collaborating with Dongjin Semichem to develop high-performance EUV photoresist, aiming for domestic supply of this critical semiconductor material and reducing reliance on Japan [1][4]. Group 1: Development and Collaboration - SK Hynix requires materials with performance superior to Japanese products, specifically seeking to improve the sensitivity of photoresists to enhance production efficiency [1]. - The company has not denied the reports but stated that specific development details cannot be disclosed, while confirming ongoing collaborations with multiple companies to improve production efficiency [1]. Group 2: Market Context and Dependency - The necessity for photoresist development has increased with the rising number of EUV layers in DRAM, with expectations for further increases in EUV technology for products below 10nm [3]. - Currently, Japanese suppliers dominate the high-end photoresist market, particularly in advanced processes below 7nm, leading to a significant dependency of Korean companies like SK Hynix and Samsung on Japanese suppliers [3]. - South Korea's dependency on Japanese photoresist imports has decreased from 93.2% in 2018 to an estimated 65.4% in 2024, alongside a 62.5% drop in imports of high-purity hydrogen fluoride from Japan [3]. Group 3: Challenges Ahead - SK Hynix previously achieved partial domestic production of EUV photoresist through its subsidiary SK Materials Performance, but this was limited to lower-spec products [4]. - The complexity of EUV photoresist technology is significantly higher than that of traditional ArF photoresist, posing challenges for South Korea to achieve self-sufficiency in advanced semiconductor processes [4]. - The development of materials requires substantial time and investment, with high entry barriers in the EUV photoresist market, making it difficult to predict the outcomes of the collaboration between SK Hynix and Dongjin Semichem [4].
