Impact of Stellantis’s $13 Billion U.S. Investment on Japanese Auto Parts Suppliers

AISIN Expected to Benefit from Expanded Opportunities

On October 15, Stellantis announced that it will invest $13 billion in the United States over the next four years. The company plans to increase domestic vehicle production by about 50% and create more than 5,000 new jobs. The investment will target plants in Illinois, Ohio, Michigan, and Indiana, and will include the launch of five new models and 19 product upgrades. Stellantis described this as the largest U.S. investment in its corporate history.

Strategic Intent under the New CEO
Antonio Filosa, who became CEO in June 2025, stated that this investment is aimed at preparing for potential U.S. tariffs and revitalizing the company’s American operations. According to Reuters, tariffs on imported vehicles to the U.S. are expected to cost Stellantis about $1.7 billion in 2025. Against this backdrop, the company seeks to strengthen localization by increasing its share of U.S.-based production. The initiative is also positioned as a countermeasure to the high share of imports in Stellantis’s U.S. sales in 2024.

Former CEO Carlos Tavares admitted in June 2024 that his own “arrogance” contributed to delays in addressing U.S. market challenges. The new strategy under Filosa reflects an explicit acknowledgment of those issues.

Competitive Context
Stellantis’s U.S. investment also aligns with shifts at GM and Ford, which are revising strategies around hybrids and adjusting EV-related plans. The investment is therefore seen as a step to secure competitiveness across multiple powertrains, including internal combustion and hybrids.

AISIN’s Relationship with Stellantis
AISIN (Ticker: 7259) was recognized as “Supplier of the Year” by Stellantis in 2023. AISIN Europe and Stellantis also announced a strategic partnership in automatic transmission repair. Furthermore, AISIN’s 2025 Integrated Report states that its North American operations have begun supplying HEVs to both Toyota and Stellantis.

With Stellantis expanding U.S. production and emphasizing local sourcing, suppliers with an established presence and track record in North America are well positioned. AISIN, already a global Tier-1 supplier with a strong footprint, is therefore expected to benefit from increased business opportunities.
