GM, Samsung pause $3.5bn Indiana battery plant

General Motors and Samsung SDI have paused construction of their battery cell plant in New Carlisle, Indiana, the companies said on May 14, halting work on a project they had previously described as a $3.5 billion investment. GM said the pause is meant to “align production capacity with current demand,” without giving a revised opening date for the site. The project had been one of GM’s main planned additions to its U.S. battery footprint as the automaker expanded electric-vehicle production with outside partners. The companies said they will provide updated plans for the site later. ### What exactly did GM say about the pause? A GM spokesperson told Indiana public radio station WVPE in an emailed statement on Thursday that “construction of the battery cell plant in New Carlisle, Indiana will be paused to align production capacity with current demand.” The statement did not say how long the pause would last or whether the companies still expect the plant to start production in 2027. (wvpe.org) The same statement said GM and Samsung SDI “will communicate plans for the site at a future date.” St. Joseph County Economic Development Director Bill Shalliol told WVPE that the county is working with GM, the state and other partners, and that work will continue to secure the site.

Samsung SDI said on Aug. 28, 2024 that the joint venture would invest about $3.5 billion in the Indiana plant and target mass production in 2027. The company said the factory would start with annual capacity of 27 gigawatt-hours and later expand to 36 GWh. The New Carlisle site covers 680 acres and was expected to create more than 1,600 jobs, Samsung SDI said at the time. (wvpe.org) The plant was set up to make nickel-rich prismatic battery cells for future GM electric vehicles. ### Why is this site important to GM and Samsung SDI? Mary Barra, GM’s chair and chief executive, said when the venture was finalized that the plant was part of GM’s effort to build battery capacity in the United States. (news.samsungsdi.com) Samsung SDI Chief Executive Yoon-ho Choi said the factory would serve as a U.S. production hub for the company’s battery business. The Indiana facility was also distinct inside GM’s battery strategy because Samsung SDI’s prismatic cells differ from the pouch-cell format used in GM’s Ultium Cells ventures with LG Energy Solution. Samsung SDI said the New Carlisle plant would supply batteries for upcoming GM electric vehicles, though neither company has publicly identified a full vehicle allocation for the site.

GM reported first-quarter 2026 revenue of $43.6 billion and net income attributable to stockholders of $2.6 billion on April 28, while raising its full-year adjusted EBIT guidance to $13.5 billion to $15.5 billion. The earnings release did not announce the Indiana pause, but it showed GM continuing to adjust capital and operating assumptions across its business this year. (news.samsungsdi.com) Cox Automotive said in its March 25, 2026 industry outlook that U.S. new-EV sales in the first quarter fell 28% from a year earlier to about 212,600 units, according to industry reports citing the company’s data. GM did not directly tie the Indiana decision to that market figure, but its statement pointed to “current demand” as the reason for pausing work.

WVPE reported that the plant’s construction contractor had laid off some employees in the fall of 2025, during a broader period when automakers were pulling back on EV production. Local reporting this week said the new pause follows that earlier slowdown in activity at the site. (electrek.co) The earlier construction changes did not end the project, and GM’s latest statement stops short of canceling it now. The companies instead said they will update the market later on what comes next for the Indiana plant. ### What happens next in New Carlisle? St. Joseph County officials said the immediate next step is securing the New Carlisle site while GM, Samsung SDI, Indiana officials and local partners continue discussions. (wvpe.org) GM and Samsung SDI have not given a new production target date or a date for restarting construction. GM’s next scheduled shareholder payment is a quarterly dividend of $0.18 per share on June 18, 2026, according to its first-quarter earnings release, and the company said investors can follow updates through its investor relations channels. For the battery project itself, the companies said only that future plans for the Indiana site will be communicated later. (investor.gm.com) (wvpe.org)
