Core Viewpoint - The long-term trend of domestic substitution for analog chips will not change regardless of tariffs, but tariffs may accelerate the pace of substitution [4][5]. Group 1: Domestic Substitution Dynamics - The urgency for domestic substitution increases with supply chain security concerns, especially during trade conflicts [5][6]. - Even without tariffs, companies are likely to seek domestic alternatives due to long-term supply chain safety [5][6]. - The high barriers to entry in the analog chip market make it difficult for companies to switch suppliers once they have established a relationship with a foreign brand [4][7]. Group 2: Market Share and Competition - Currently, foreign brands dominate the analog chip market, holding over two-thirds of the market share, while domestic brands have a much lower penetration rate [7][8]. - The gap in market share is primarily due to the historical development of the semiconductor industry, where foreign companies established a strong foothold before domestic companies could catch up [7][8]. - Government support is crucial for increasing domestic market share, as the high barriers to entry make it challenging for domestic firms to compete [7][8]. Group 3: Pricing and Cost Considerations - Even with significant tariff increases, the cost of analog chips remains a small portion of total product costs, leading companies to accept price hikes rather than immediately switch suppliers [9][10]. - Companies are likely to conduct research and development to find alternatives but will not rush to replace existing suppliers due to the associated costs and risks [9][10]. Group 4: Supplier Relationships and Customization - Many clients prefer to work with multiple suppliers for analog chips, often choosing foreign brands as primary suppliers due to established relationships and perceived quality [10][11]. - Domestic suppliers can gain an advantage through better communication and service, especially in industries requiring high customization [10][11]. Group 5: Technology and Experience - The technical challenges in analog chip production are more about experience and stability in complex environments rather than sheer technological complexity [12][13]. - Domestic companies are gradually closing the experience gap with foreign competitors, and the potential for catching up exists as they gain more opportunities [13][14]. Group 6: Financial Performance and Valuation - Recent profitability in domestic analog chip companies may not reflect true financial health due to the mismatch between expenses and revenue generation timelines [16][18]. - The long-term value of these companies should be assessed based on their potential to expand product lines and market share rather than short-term profits [19][20]. - The growth in the number of product SKUs is essential for domestic companies to compete effectively, as a broader product range allows for one-stop procurement for clients [17][20].
