Samsung SDI Returns to Profit as US Storage Orders Pass 60 GWh
Samsung SDI reported a third-quarter operating profit on 29 October 2026, a year after a loss, and said US demand for energy storage batteries is a main driver. The story is about large storage systems, but it shows where battery cell supply is heading.
What Samsung SDI reported
According to Money Today, the Korean battery maker posted an operating profit of 407.8 billion won for the quarter, a swing back into profit. The figure was roughly double the previous quarter and the largest since the third quarter of 2023. DigitalToday reports the same profit figure and says the company lost 591.3 billion won a year earlier. Revenue rose 52.6% year on year.
The company attributes the improvement to demand for energy storage systems and battery backup units, which it links to investment in AI data centres.
The US storage orders
Samsung SDI says it has won more than 60 GWh of energy storage orders in the United States since the start of 2026. It describes its Synergy Cells plant in Indiana as a production hub for these batteries and plans to expand it in phases. Money Today also reports that mass production of prismatic LFP cells began in October at the Star Plus Energy plant in the US.
The company expects the storage trend to continue in the fourth quarter. These are company statements made on an earnings day, and we have not been able to verify the order book independently.
What this means for home batteries
Home batteries and grid-scale storage often use the same cell chemistry, particularly LFP, which our article on battery safety and chemistry explains. When large buyers order cells at scale, manufacturers add capacity, which can eventually help households too.
We could not find anything in these reports that links Samsung SDI's results to UK or European home battery prices, so we are not drawing a conclusion about costs. If you are planning a purchase, the home battery calculator is a better guide to your own numbers than any manufacturer's earnings.
