Summary of the Conference Call for Xinquan Co., Ltd. Company Overview - Xinquan Co., Ltd. is a leading domestic automotive parts supplier, primarily focusing on interior components such as dashboard assemblies, which account for approximately two-thirds of its revenue. The company holds a market share of nearly 20% in the domestic market. Key clients include Chery, Geely, Tesla, and rapidly growing companies like Li Auto, BYD, and Xiaomi [3][4]. Financial Performance - In 2024, Xinquan achieved a revenue of 13.2 billion yuan, representing a year-on-year growth of 25.5%. The net profit attributable to shareholders was 977 million yuan, up 20%. The gross margin was 19.6%, slightly down due to accounting policy changes, but actual profitability remained stable [2][4]. - For Q1 2025, the company reported a revenue of 3.52 billion yuan, a year-on-year increase of 15.5%, with a net profit of 210 million yuan, showing a slight increase. The gross margin was 19.5% [6][2]. - The company expects a revenue of over 17 billion yuan in 2025, with profits exceeding 1.3 billion yuan, corresponding to a valuation of less than 16 times earnings [4][14]. Growth Drivers - Short-term growth is driven by the ramp-up of new products (exterior parts and passenger car seats) and expansion into overseas markets. The exterior parts are expected to generate 1.2 to 1.3 billion yuan in revenue, primarily from Chery [2][7]. - The passenger car seats segment, bolstered by the acquisition of a 70% stake in Anhui Ruichi, is projected to contribute 600 to 700 million yuan in revenue [8][2]. International Expansion - Xinquan is expanding its overseas market presence through a "local for local" strategy to mitigate geopolitical risks. Factories in Malaysia and Mexico are operational, with a Slovakian factory set to commence production soon. The Mexican factory is expected to generate 600 million yuan in revenue in 2024 and 2.5 billion yuan in 2025, with a profit margin higher than domestic operations [9][11][12]. - The Mexican factory's capacity utilization has rapidly increased to 80%-90%, nearing full production capacity. Future growth is anticipated with the launch of new Tesla models [11][12]. Strategic Positioning - Xinquan aims to transform into a comprehensive global supplier of interior and exterior solutions, leveraging its global footprint and product expansion. The company is currently valued at a low range, making it a recommended investment in the automotive parts sector [4][14]. - The company is also strategically positioned in the Southeast Asian market to capture demand from regional clients [10]. Key Risks and Considerations - The slight decline in gross and net profit margins is attributed to changes in accounting policies, which impacted the recognition of warranty costs. However, the underlying profitability remains stable [5][2]. - The performance of Tesla's Model Y during its update cycle has influenced revenue contributions, particularly in the first quarter of 2025 [6][2]. Conclusion - Xinquan Co., Ltd. is well-positioned for future growth through product diversification, international expansion, and a focus on high-margin segments. The company’s strategic initiatives and market positioning make it a compelling investment opportunity in the automotive parts industry [3][4][14].

The PTA business turned profitable with a net profit of around 75 million yuan. Overall performance showed a slight year-on-year increase despite a nearly 100 million yuan asset impairment provision [2][4][3]. Impact of Tariff Policies - The direct impact of tariff policies on New Feng Ming is limited, but there are significant indirect effects through fluctuations in crude oil futures prices and downstream exports. April's production and sales rate was affected, but by the end of April, the cumulative production and sales rate exceeded 100%, leading to a decrease in inventory [2][6]. Production and Sales Outlook - For May 2025, the company expects a production and sales rate to maintain a good level, currently at 70%-80%. The company plans to adjust product price differentials based on raw material prices and inventory levels, focusing on operational improvements in May and June [2][7]. Price Trends in Long Fiber Products - The price trends for long fiber products in 2025 differ significantly from 2024.

Leading companies like New Feng Ming and Tongkun are slowing down production rates to better manage market supply and improve product quality [2][11]. Capacity and Capital Expenditure Plans - New Feng Ming's short fiber capacity is 1.2 million tons, leading the industry. PTA capacity is currently 7.7 million tons, with an additional 2.5 million tons expected in November, totaling 10 million tons. Future capital expenditures are projected to significantly decrease, with 2025 expected to be around 5-6 billion yuan [5][12][13].

The inventory level was between 25 to 27 days, which is considered manageable [2][8][21]. Production Operations - The current operating rate is stable at 90%-92%. Although some equipment is under maintenance, overall production operations are in good condition. The company has engaged in a 10% production cut in April as part of industry-wide coordination [2][15]. Future Demand for Long Fiber - Despite challenges in the raw materials market, the demand for long fiber remains strong due to its affordability and high cost-performance ratio. The company achieved a production and sales rate of approximately 108% in April, indicating robust demand [2][16]. Management Optimization - New Feng Ming is transitioning from a centralized management model to a more decentralized approach, enhancing operational efficiency and cost management [2][18]. PTA Base and Future Trends - The PTA base is strategically located near the long fiber base, providing competitive advantages. The company expects to phase out older PTA facilities in the next 3 to 5 years, enhancing overall efficiency [2][20]. Adjustments Based on Inventory Levels - The company typically takes action when inventory exceeds 30 days, but it has improved its capacity to manage inventory pressure, allowing for more flexible responses based on market conditions [2][22].
