Anji Technology makes CMP polishing slurry and functional wet electronic chemicals, and is a core play on domestic substitution in semiconductor materials, with 2025 revenue of 2.504 billion yuan. Import substitution is converting strongly, but at roughly 230 yuan and a PE above 60x the market has already priced in second-curve businesses such as electroplating solutions, leaving no margin of safety against a conservative intrinsic value. Rating Hold: the fair buying range is 135 to 145 yuan, and a more visible pullback is needed before building a position in tranches.
JSR is a leading Japanese semiconductor materials company focused on key chipmaking materials such as photoresists, CMP slurry, and cleaning solutions, with the world's top share in ArF photoresists. The core thesis is that its electronic materials franchise is high quality, but the group is delisted, still restructuring, and burdened by weaker life sciences assets and a heavier balance sheet. Rating Watch: a potentially valuable restructuring case to track, but not an executable public-market buy today.
Shengyi Technology is one of China's leading copper-clad laminate (CCL) producers, with about 12% global share in rigid CCL and the second-largest global position, supplying CCL, prepreg, and printed circuit boards into communications, server, and automotive electronics PCB supply chains. Revenue reached RMB 28.4 billion in 2025 and net profit attributable to shareholders reached RMB 3.3 billion, helped by a clear recovery driven by AI servers and high-speed materials demand. Research rating Avoid: a solid company, but the current price appears far ahead of verifiable long-term cash-flow value.
Taiwan Elite Material (EMC) is Taiwan's leading supplier of high-end copper-clad laminates (CCL) and laminate materials, serving PCB makers and the AI server and high-speed switch supply chains. It holds 34.4% global share in halogen-free CCL and about 13.3% overall, with a leading position in high-speed, low-loss niches; in 2025, revenue reached NT$94.3 billion, net margin was 15.5%, and ROE was 34.25%, placing its earnings quality among the stronger names in materials manufacturing. Research rating Watch: a high-quality materials leader, but today's price has pulled forward too much of the next 5 to 10 years of growth.
Tokyo Ohka Kogyo (TOK) is a key global supplier of semiconductor photoresists and high-purity chemicals, serving advanced-node foundries including TSMC. FY2025 revenue and profit attributable to owners reached record highs, the balance sheet remained in a net cash position, and the equity ratio was close to 68%, but free cash flow is still well below accounting profit during a heavy capex cycle. Research rating Watch: a high-quality semiconductor materials compounder, yet at roughly ¥9,700 the stock is already near the upper end of an optimistic valuation range and lacks a sufficient margin of safety.
Peric Special Gases is China's leading electronic specialty gases supplier, focused on chipmaking-critical gases such as nitrogen trifluoride and tungsten hexafluoride, ranking No. 1 in China and No. 9 globally by integrated-circuit electronic specialty gas sales revenue in 2024. The core thesis is that 2025 revenue reached 2.26 billion yuan, operating cash flow remained healthy, net cash was about 2.46 billion yuan, and the balance sheet was solid, but ROE has fallen from 22% to 6%, free cash flow remains under pressure, and the current PE TTM of about 370x and PB of about 22.75x are far detached from fundamental support. Rating Avoid: a capable business whose stock price has already consumed too much of the optimistic long-term story upfront.
Shin-Etsu Chemical is one of Japan's largest diversified chemical groups, anchored by world-leading semiconductor silicon wafers and lithography-related materials, with electronic materials contributing 54% of operating profit, alongside one of the world's largest PVC platforms and a silicone business. FY2026 revenue was JPY 2.57 trillion, operating margin was 24.7%, and net cash exceeded JPY 1.42 trillion, giving the company an exceptionally strong balance sheet. Research rating Watch: a high-quality compounder, but the current share price of about JPY 6,863 implies roughly 27x trailing PE and leaves insufficient margin of safety.
SUMCO is the world's second-largest semiconductor silicon wafer manufacturer, focused on high-precision 300mm wafers, with roughly 30% global share and more than 50% share in wafers for leading-edge logic chips, deeply embedded in the TSMC, Samsung, and Kioxia supply chains. FY2025 revenue was ¥409.7bn, while depreciation pressure and the cycle trough drove a net loss attributable to owners of ¥11.8bn, with Q1 FY2026 still loss-making and net debt at roughly ¥263.9bn as the heavy-asset capacity expansion cycle remains unfinished. Research rating Watch: the current share price of roughly ¥3,499 is already near the upper end of the optimistic valuation range, leaving insufficient margin of safety and making the stock better suited for a watchlist pending a price pullback.
Entegris is a global leader in semiconductor purification consumables, with about 75% of revenue tied to annuity-like materials consumed as wafers are produced. Its core thesis rests on certified-in filters, CMP slurries, specialty materials and gases, and wafer carriers, with no single product platform above 3% of sales and very high switching costs once qualified into fab processes. Research rating Watch: a high-quality compounder and one of the cleanest AI pick-and-shovel cash-flow stories, but the current price leaves little margin of safety.
A maker of high-end electronic metal powder materials, lead drafter of the "Capacitor Electrode Nickel Powder" industry standard, with genuine technical barriers; but at 165.8 yuan the stock trades at roughly 172x trailing PE and 24x PB, while the upper bound of the optimistic DCF case is only 50 yuan, a 232% premium. Rating Avoid: a real technology paired with a bad price, with an ideal buy range of 7-12 yuan.
