On July 26, 2026, Samsung Electronics officially announced that its Exynos Auto V series of automotive-grade chips based on 5nm EUV technology had passed the AEC-Q100 reliability certification and secured volume orders from several leading Chinese EV manufacturers, with deliveries scheduled to begin in Q4 2026. This breakthrough marks a critical step for Asian automotive chips in advanced process technology and injects new growth expectations into the Asian chip sector in the US stock market.

Core Event: Samsung Captures High Ground in Advanced Automotive Chip Process

The certified chips include the Exynos Auto V920 and V922, targeting smart cockpits and autonomous driving domain controllers respectively. AEC-Q100 is a reliability standard set by the Automotive Electronics Council; passing this certification means the chips can operate stably in extreme environments from -40°C to 150°C, meeting automotive-grade requirements. Samsung Electronics' foundry business president stated, "This is the world's first 5nm automotive chip to pass AEC-Q100 certification. We will use this as an opportunity to accelerate cooperation with global OEMs and Tier 1 suppliers." The initial orders come from BYD, Geely, and NIO, totaling over 2 million units, primarily for new models launching in 2027.

Background: Asian Automotive Chip Ecosystem Under the RCEP Framework

With the deepening implementation of the Regional Comprehensive Economic Partnership (RCEP), synergies in the Asian semiconductor supply chain have become increasingly significant. In the first half of 2026, intra-Asian automotive chip trade volume grew 23% year-on-year, with China's imports of automotive chips from South Korea and Japan rising to 38%. RCEP's cumulation rules allow chip design, manufacturing, and packaging to flow freely within the region, while tariff reductions lower end costs. Samsung chose to mass-produce at its Hwaseong plant in South Korea and export finished products to China under RCEP rules, enjoying zero tariffs, further enhancing price competitiveness.

Impact on the Asian US Stock Sector

Following the news, during US trading on July 26, Samsung Electronics (SSNLF) rose 3.2%, driving gains in other Asian automotive chip-related stocks. TSMC (TSM) edged up 0.8% on expectations of receiving some outsourced orders from Samsung; competitor Renesas Electronics (RNECY) fell 2.1%. Meanwhile, US-listed Chinese chip stocks such as SMIC and Hua Hong Semiconductor also showed movement. Analysts noted that Samsung's breakthrough will intensify competition in advanced automotive chip processes, but overall benefits the Asian supply chain, especially companies with advanced packaging and testing capabilities.

US Stocks Worth Watching

  • Samsung Electronics (SSNLF): Directly benefits from order growth, with automotive chip revenue expected to exceed $5 billion in 2027.
  • TSMC (TSM): If Samsung's capacity falls short, TSMC's N5 automotive platform may receive diverted orders.
  • Amkor Technology (AMKR): Provides packaging services for Samsung; rising demand for Asian automotive chips boosts capacity utilization at its South Korea plant.
  • ON Semiconductor (ON): Though a US company, its silicon carbide automotive chip business in Asia will also benefit from positive sentiment.

Industry Trend Analysis: Dual Drivers of Advanced Processes and Cross-Border Trade

The electrification and intelligence of vehicles demand higher chip computing power, power efficiency, and reliability, driving automotive chips from 28nm to 5nm and even 3nm. According to IC Insights, the global automotive chip market is expected to reach $62 billion in 2026, with the Asia-Pacific region contributing 55%. On the cross-border trade front, RCEP tariff reductions and facilitation measures lower export costs for Asian chip companies, while the rise of Chinese EV manufacturers provides a huge market for Korean and Japanese chip firms. Samsung's collaboration is a typical example of the "technology + market" dual-drive model.

Notably, Japan's Ministry of Economy, Trade and Industry recently released the "Automotive Chip Supply Chain Strengthening Plan," investing 1 trillion yen to support advanced process localization in Japan. These policy moves will further consolidate Asia's dominant position in the global automotive chip supply chain and continue to attract US capital attention.

Risks and Outlook

Despite the positive outlook, three key risks remain: first, US-China tech frictions may impose restrictions on Samsung's supply of advanced chips to China; second, whether Samsung's 5nm yield ramp-up can meet stringent automotive requirements; third, competitors TSMC and Intel are also accelerating their advanced automotive chip layouts. Looking ahead to the second half of 2026, Asian automotive chip US stocks are expected to continue a volatile upward trend. Investors should focus on order fulfillment and national industrial policy developments.
