Shares of Samsung SDI surged 7.5% to KRW 459,000 on August 10, snapping a months-long slump, after the company confirmed it will begin producing a cheaper type of battery at its U.S. plant in October and start shipping a new large-scale energy-storage product to customers before year-end. The announcement marks a pivotal turn for a company that just clawed back to operating profitability after seven consecutive losing quarters. Samsung SDI's American Energy-Storage Pivot Is Electrifying Shares — But Is One Factory Enough to Outrun Chinese Rivals?
Shares of Samsung SDI vaulted 7.5% to KRW 459,000 on August 10 after the company confirmed its U.S. factory will begin producing cheaper, iron-based battery cells in October and start shipping containerized energy-storage units to customers before year-end. For a stock battered by seven straight quarters of operating losses, the announcement signals that a strategic bet on grid-scale batteries — not just electric vehicles — may finally be paying off.
A Profitable Quarter Changes the Narrative. Samsung SDI posted Q2 2026 revenue of KRW 3.77 trillion (roughly US$2.59 billion), up 18.5% year-over-year, with operating profit of KRW 203.8 billion — its first profitable quarter since Q3 2024.
The recovery was fueled by strong demand from AI data-center applications, improved product mix, and U.S. manufacturing tax credits. Investors are pricing in the possibility that energy storage, not EVs, will anchor the next growth chapter.
U.S. Rules Are Handing Samsung a Competitive Edge. Producing domestically lets Samsung SDI collect production tax credits while its customers claim investment tax credits, including a 10% bonus for domestic content. Since the One Big Beautiful Bill Act passed, projects using Chinese-imported cells are no longer eligible for those credits. That regulatory wall effectively blocks China's CATL and BYD from the most lucrative U.S. incentive pool, handing Korean manufacturers a structural pricing advantage.
The Order Book Stretches to 2029 — But Capacity Is the Bottleneck. Samsung SDI reported "strong momentum in order intake," with secured orders covering substantial capacity through 2029 and demand expected to exceed production from 2028 onward.
A single anchor contract, signed late last year, is valued at over KRW 2 trillion (~$1.35 billion) over three years.
The company has since added another roughly KRW 1.5 trillion order and is in discussions for more. The risk: Samsung SDI targets 30 GWh of annual U.S. storage-cell capacity by year-end 2026 , yet global lithium-battery storage shipments already hit 461 GWh in H1 2026 alone, up 71% year-over-year. Scaling fast enough to capture share against aggressive Chinese pricing abroad remains the central question.
Pivoting Away from a Shrinking EV Market. Samsung SDI is converting EV battery lines at its Indiana plant to produce storage cells , a pragmatic response after EV battery sales slowed sharply when U.S. consumer EV tax incentives ended in September 2025. The pivot is smart, but it also reveals how dependent this rally is on a single business line in a single geography. If U.S. energy policy shifts or capacity expansion stalls, today's optimism could unwind just as fast as it arrived.
