Key Points:
- SK On officially ended its joint venture with Ford, renaming the Tennessee facility as “SK On Tennessee” and taking full independent ownership.
- Ford will assume full ownership and operation of the two battery factories located in Kentucky under the restructuring agreement.
- The corporate split reduces SK On’s debt burden by roughly 5.4 trillion won, which equals about $3.6 billion.
- The restructuring will save SK On around $180 million in annual interest costs and lower its depreciation expenses by 330 billion won.
South Korean battery manufacturer SK On announced on Thursday that it has officially dissolved its joint venture with Ford Motor Company. The move allows both companies to own and operate their electric-vehicle battery plants separately in the United States. This strategic split officially dismantles the once-heralded partnership as both firms navigate a cooler market for electric vehicles.
As part of the restructuring, SK On has taken full ownership of the battery plant in Stanton, Tennessee. The South Korean manufacturer renamed the site “SK On Tennessee” and immediately began independent operations at the facility. Meanwhile, Ford took sole ownership of the two large battery plants in Glendale, Kentucky, which the companies previously planned to run together under their joint business.
The final transition comes exactly five months after the two corporations first announced their intentions to end the partnership. The partners originally set up the 50-50 joint venture, called BlueOval SK, back in 2022. At the time, both automotive players expected a massive wave of electric-vehicle demand in North America, prompting them to plan an enormous $11.4 billion joint investment across the three factories.
The corporate breakup brings massive financial relief to SK On, which has struggled with high interest rates and heavy capital expenditure in recent years. By walking away from the Kentucky facilities, SK On estimates it will reduce its overall debt burden by roughly 5.4 trillion won, or about $3.6 billion. Shifting this massive chunk of debt off its balance sheet greatly improves the firm’s long-term financial health.
In addition to the debt reduction, SK On expects the new arrangement to yield significant ongoing savings. The company estimates it will save around $180 million every year in interest costs alone. Furthermore, the battery maker will no longer have to account for the heavy depreciation expenses tied to the Kentucky plants. This change will lower its annual depreciation costs by approximately 330 billion won.
Executives at SK On believe the independent structure will allow the firm to respond much more quickly to a rapidly changing market. An SK On official explained that the company can now manage its U.S. manufacturing footprint with much greater autonomy. The independent base in Tennessee gives SK On the freedom to pursue other customers, such as stationary energy storage businesses, rather than relying solely on Ford’s production schedules.
The dramatic shift in the SK-Ford relationship reflects a much larger downturn in the global electric vehicle sector. When the companies launched the venture in 2022, federal subsidies and supportive policies from the Joe Biden administration sparked a gold rush in domestic battery manufacturing. However, growth in consumer adoption of electric vehicles has slowed significantly over the past two years, forcing automakers to adjust their aggressive transition timelines.
Adding to the market pressure, political changes in Washington have introduced deep uncertainty for clean energy firms. The administration of President Donald Trump has signaled a potential rollback of key federal subsidies and fuel-economy regulations. This looming policy shift has forced battery suppliers and car companies to rethink their expensive factory buildouts to avoid getting stuck with excess production capacity.
The dissolution of the joint venture is not the only sign of trouble for SK On’s American operations. In March, the South Korean firm laid off 968 employees at its independent battery factory in Georgia. These job cuts are directly aligned with the broader industry-wide push to control costs, as battery demand from major automakers remained far below original forecasts.
By separating their assets, both SK On and Ford hope to weather the current industry storm on their own terms. Ford can now integrate its Kentucky plants into its own shifted product strategy, which increasingly emphasizes hybrid models and utility-scale energy storage. For SK On, the split provides a vital financial lifeline, freeing up billions of dollars in capital while preserving a critical manufacturing foothold in the North American market.
