Samsung SDI’s planned $3.5 billion battery factory in Indiana is on hold, and the situation is looking more uncertain by the day. The joint venture with General Motors in New Carlisle, Indiana has been paused, with no clear timeline for when construction might actually begin.
Had everything gone according to plan, the facility would have entered mass production in fall 2027, churning out enough battery cells to power roughly 300,000 EVs annually. That timeline is now off the table.
What’s driving the delay?
The short answer is a softening US EV market. In Q1 this year, EV sales dropped roughly 30 percent year-over-year to around 213,000 units, making up just 5.8 percent of total car sales. The Trump administration’s decision to end federal EV tax credits last September didn’t help matters either, pulling up to $7,500 in consumer incentives out of the picture.
GM is reportedly weighing several options behind closed doors. One possibility is switching the battery chemistry entirely, moving to lithium iron phosphate cells, which are cheaper to produce and increasingly common among automakers looking to trim costs. The other, more drastic option is GM exiting the venture altogether. That’s not without precedent. Last year, GM walked away from its third Michigan plant, a 50/50 deal with LG Energy Solution, offloading it for $2.14 billion.
For now, Samsung SDI has kept its public response carefully neutral. According to Korea JoongAng Daily, the company said the two firms “continue to work together and will discuss future plans.” Not exactly a ringing endorsement of the project’s health.
Samsung SDI’s finances add pressure
The timing is awkward for Samsung SDI. The company reported an operating loss of 1.72 trillion won last year, a significant swing into the red after years of aggressive expansion. Its Q1 loss this year was smaller, but a narrowing loss is still a loss. Committing billions to a factory in a market that’s pulling back requires a level of confidence that’s hard to justify right now.
Whether GM and Samsung SDI find a way to restructure the deal or part ways entirely, the Indiana project is a clear sign of how quickly the EV investment boom has cooled. We’ll keep you updated as the situation develops.
