Earnings call transcript: Samsung SDI Q3 2025 sees revenue dip, innovation in focus

Samsung SDI reported a 22.5% year-over-year revenue decline to ₩3.1 trillion in Q3 2025, incurring an operating loss of ₩591 billion, though net income was positive at ₩5.7 billion primarily due to the sale of its polarizer film business. Facing sluggish EV battery demand, the company is strategically converting U.S. EV battery production lines to focus on the high-growth Energy Storage System (ESS) market, aiming for 30 GWh capacity by late 2026, and developing new battery types for volume EV segments. Samsung SDI anticipates narrowing operating losses in Q4 and, having secured ₩1.1 trillion from the asset sale, plans no additional capital increases while emphasizing growth in ESS, AI-related semiconductor materials, and humanoid robotics.

Analysis

Samsung SDI reported a Q3 2025 revenue decline of 22.5% year-over-year to ₩3.1 trillion, resulting in a negative operating income of ₩591 billion. This underperformance stemmed primarily from sluggish EV battery demand and slow small battery recovery. Net income reached ₩5.7 billion, boosted by a ₩1.1 trillion cash inflow from its polarizer film business sale.

The company is strategically pivoting towards high-growth areas, notably the U.S. Energy Storage System (ESS) market, aiming for 30 GWh capacity by late 2026 through EV line conversion. As the sole non-Chinese prismatic ESS provider in the U.S., Samsung SDI targets a rapidly growing market. Electronic materials for AI-related semiconductors and high-power cylindrical batteries for humanoid robotics and data center BBUs are also emerging growth drivers.

Management anticipates narrowing Q4 2025 operating losses, supported by strategic shifts and optimized investments. The asset sale's cash inflow bolsters financial stability, precluding additional capital increases. Growth opportunities are expected in ESS, small batteries, and electronic materials, despite a challenging EV market.

Key Decisions for Investors

• Monitor Samsung SDI's execution of its strategic pivot into the U.S. ESS market, leveraging its unique prismatic product offering and planned 30 GWh capacity by late 2026
• Evaluate the growth trajectory and profitability contributions from diversified segments including AI-related semiconductor materials, humanoid robotics, and data center Battery Backup Units (BBUs) as key offsets to EV market challenges
• Assess the company's enhanced financial stability from the ₩1.1 trillion asset sale and its commitment to no additional capital increases, while observing Q4 operating loss narrowing
• Watch for any signs of recovery in the broader EV market and the progress of Samsung SDI's LFP and mid-nickel prismatic battery development for future volume and entry-level segments
