Ford and SK On to end battery joint venture. What it means in Tennessee

SK On and Ford have restructured their BlueOval SK joint venture: SK On will assume full ownership and operation of the Tennessee battery plant at Ford’s BlueOval City in Stanton, while a Ford subsidiary will take full ownership of the Kentucky plants. The agreement, subject to customary regulatory approvals and expected to close by Q1 2026, follows prior production delays (Tennessee pushed to 2027; Ford’s full‑size EV truck mass production to 2028) and positions SK On to supply Ford and other customers and expand U.S. battery and energy‑storage manufacturing. The change effectively ends the joint‑venture governance, preserves the companies’ strategic relationship, and realigns asset control in ways that will influence production timelines and regional employment (each plant was projected to support roughly 2,500 jobs).

Analysis

SK On and Ford have agreed to restructure their BlueOval SK U.S. battery joint venture so that SK On will assume full ownership and operation of the Tennessee battery plant at Ford’s BlueOval City in Stanton, while a Ford subsidiary will take full ownership of the Kentucky plants; the transaction is subject to customary regulatory approvals and is expected to close by Q1 2026. SK On framed the change as a strategic realignment to improve operational efficiency, productivity and flexibility, and plans to use the Tennessee facility to supply Ford plus other customers and energy storage systems, positioning the site as a U.S. battery manufacturing hub.

Operational timelines remain a material uncertainty: Tennessee had been delayed (BlueOval City battery production pushed into 2027), the first Kentucky facility began production as of August, and Ford pushed mass production of its full‑size EV trucks at BlueOval City to 2028 with prototype builds slated for 2027. Each plant was previously projected to support roughly 2,500 jobs at full capacity, so the ownership split preserves regional employment expectations but staggers near‑term production ramp risk.

The split shifts control and execution risk—Ford retains the Kentucky assets while SK On gains autonomy over Tennessee—so future supply agreements, capital deployment and customer diversification are key value drivers. Investors should treat regulatory approval, concrete production start dates at Tennessee, and Ford’s truck production timeline as primary catalysts and execution risk factors that will influence near‑term financial and supply‑chain outcomes.

Key Decisions for Investors

• Monitor the regulatory approval process and confirm closing by Q1 2026 before increasing exposure to either company’s supply‑chain beneficiaries, as the timing of ownership transfer is a primary catalyst
• Reassess exposure to Ford-centric battery suppliers and assemblers given the delayed Tennessee battery start (to 2027) and Ford truck mass production delay (to 2028); consider hedging near‑term demand risk
• Evaluate opportunities in battery cell and energy‑storage component suppliers that could benefit if SK On secures third‑party customers from the Tennessee plant, but wait for firm off‑take contracts or production start confirmations
• Use near‑term operational milestones (Kentucky production ramps and Tennessee production start dates) and workforce/job announcements as triggers to upgrade or downgrade related positions
