Group 1: Financial Performance - The main reason for the profit growth in the first half of the year is attributed to the increase in sales of reverse osmosis membranes, particularly high-end products like seawater desalination membranes, which contributed to higher gross margins. Additionally, economies of scale have also boosted the gross margin [2]. Group 2: Industry Application and Revenue Sources - The company's membrane materials are widely used in water resource deep treatment, material concentration, and separation. The downstream industries are highly diversified, including coal chemical, power, metallurgy, food, pharmaceuticals, and municipal water treatment. Currently, no single industry accounts for more than 10% of revenue, with traditional industries still being the main revenue source [2]. Group 3: Market and Production Capacity - The domestic production rate of reverse osmosis membranes in the semiconductor industry is still low, currently in the early stages of promotion, and will require time for significant growth [3]. - Overseas revenue accounts for approximately 30%, primarily through partnerships with local distributors, while gradually building its own overseas after-sales service team [3]. - The current capacity utilization is at full production, meeting market demand. The design capacity disclosed in the annual report is conservative, and actual operations can further enhance capacity through equipment upgrades and increased production efficiency [3]. - Future capacity expansion plans depend on market demand, with the production base having surplus space and the ability to quickly initiate new production line construction, ensuring that capacity will not become a sales bottleneck [3].
