Stellantis is stepping back from ownership of Windsor’s marquee NextStar battery operation, handing full control to LG Energy Solution as the automaker absorbs massive EV-related charges and investors reprice the risks facing North America’s auto supply chain.
Market snapshot
| Item | What it means |
|---|---|
| Deal | Stellantis is selling its 49% equity stake in Windsor’s NextStar Energy battery plant to LG Energy Solution, giving LG full ownership. |
| Plant value | The NextStar facility is a roughly $6B operation and one of Canada’s most closely watched EV supply-chain bets. |
| Jobs | About 1,300 employees now, with a long-stated target of 2,500 as production reaches full capacity. |
| Stellantis charges | US$26.5B in charges tied to EV model cancellations and supplier compensation, highlighting the cost of reworking an electrification plan midstream. |
| Share move | Stellantis shares were down about 23% Friday morning, a blunt sign of investor concern around tariffs, margins, and EV demand durability. |
Figures reflect public company and plant statements and early Friday market trading.
Stellantis’ exit from its minority stake in Windsor’s NextStar Energy plant lands like a jolt in Canada’s EV corridor. The facility was built to anchor a new era of industrial growth in southwestern Ontario, and it has been treated as a bellwether for whether the country can win the next generation of auto investment. So when a global automaker steps away, the first reaction is obvious: is the bet wobbling?
The early signals suggest a different story. LG Energy Solution, the South Korean battery maker that founded the joint venture with Stellantis in 2022, is taking full ownership and describing operations as steady. The message out of the plant is continuity: production planning continues, the workforce remains in place, and the ramp toward a 2,500-job target is still held up as the long-term horizon.
What changed is the ownership structure. Stellantis is no longer tying capital and governance to a facility it still needs — because it still needs batteries. Instead, it is shifting to a model where supply is secured through commercial relationships while the specialist battery manufacturer runs the plant at full discretion. For a company staring at a dramatic reset in its EV program, it is a clean way to reduce exposure without severing the underlying industrial link.
Windsor’s battery plant isn’t being shuttered. It’s being placed under a single operator with a broader customer lens — and that could matter as EV demand patterns shift.
The backdrop is brutal. Stellantis disclosed US$26.5 billion in charges tied to cancelling EV models and compensating suppliers, an extraordinary figure that underscores how expensive it can be to pivot after decisions have already rippled through factories, purchasing contracts, and product calendars. Investors responded quickly, driving the company’s shares sharply lower in early Friday trading.
This is where Windsor’s story turns. A battery plant tied too tightly to one automaker’s model plan can become vulnerable when launch timelines slip or product strategies get rewritten. A battery plant run by a global supplier with a wider roster of potential customers can, in theory, keep utilization steadier — and utilization is what protects jobs and stabilizes a site through an industry transition.
LG’s public rationale leans heavily on flexibility. Full ownership allows quicker operational decisions and faster alignment with demand across North America, including growth in energy storage systems. That market has its own momentum, driven by grid investment and renewable expansion, and it offers battery makers a second lane when passenger EV growth softens in specific price tiers or regions.
The politics of the moment sharpen the economics. New U.S. tariff pressure has injected uncertainty into the Canada–U.S. auto pipeline, raising costs and complicating forecasts just as companies decide where the next wave of production should sit. At the same time, Canada has been courting South Korean manufacturing investment, and a Korean battery leader consolidating ownership of a major Canadian facility fits squarely into that narrative.
For workers, the near-term issue is security, not strategy. Unifor, representing roughly 800 NextStar employees, has emphasized that employment continues under the current collective agreement, which runs until July. The plant already supports about 1,300 jobs, and in a region where auto employment is both identity and livelihood, those numbers carry more weight than corporate phrasing.
For readers tracking the industrial chessboard, the deal is also a signal about how the EV buildout may look from here: less vertical ownership for automakers, more control for specialist suppliers, and more emphasis on flexibility over symbolism. In that environment, the most resilient sites may be the ones that can serve multiple customers and multiple end markets without being trapped by a single product lineup.
Windsor’s NextStar facility was always bigger than one company. It sits at the intersection of Canadian industrial policy, labour expectations, and North America’s reconfigured supply chain. If LG can keep the plant running hot — and attract additional North American customers — the ownership change may end up looking less like a retreat and more like an insurance policy for the factory’s long-term viability.
What readers want to know
- Is the plant closing? The public message from LG is that operations continue with no disruption.
- Are layoffs expected? The stated position is no job losses expected, with union terms continuing.
- Why is Stellantis selling? The company is absorbing US$26.5B in EV-related charges and appears to be reducing ownership exposure while keeping supply access.
- What could change next? LG has full control, which may help the facility respond faster to shifting EV and energy storage demand.
Broader market coverage of Stellantis’ EV reset and the share reaction has been tracked by market reporting.
For Windsor, the story is no longer only about whether Canada can land a next-generation plant — it already did. The question now is whether that plant can stay stable through tariff shocks, shifting demand, and corporate restructurings while still delivering the employment scale it was built to support. On Friday, the strongest word attached to NextStar wasn’t “exit.” It was “continuity.”
