Core Viewpoint - Guangxin Materials held a performance briefing on November 4, 2025, discussing its business operations, core business progress, and future strategic plans with investors [1] Business Progress - The company has developed environmentally friendly graphene water-based coatings and solvent-free high-solid coatings for the marine anti-corrosion market, which have passed NORSOK M-501 standard testing and some customer site tests. These products are applicable to high-end marine equipment such as offshore oil and gas platforms and wave energy generation equipment. The company expects to achieve bulk sales in strategic core markets between Q4 2025 and Q2 2026 [2] Capacity and Performance - The Longnan base achieved over 150 million in revenue in the first three quarters of 2025. The company reported a net loss of 4.77 million in Q3 2025, primarily due to lower-than-expected revenue from photovoltaic BC battery insulation glue, fixed asset depreciation from the Longnan base, and impairment losses from the sale of a subsidiary. However, excluding credit and asset impairments, the company showed slight operational profitability [3] Strategic Focus - The company has been divesting loss-making assets such as Shenzhen Lejian and Hunan Sunshine to optimize its structure and reduce operational costs. The sale of a subsidiary for 9.8 million is part of this strategy. The company emphasizes that these transactions will not significantly impact production operations. The photolithography and related materials segment is benefiting from PCB market growth driven by AI and robotics, with a focus on providing cost-effective solutions. The company has completed a refinancing process for specific stock issuance in 2024 and currently has no other refinancing plans [4]
