SK Hynix, Stellantis Lead $5.5B Factory Investments

Six companies, led by SK Hynix and Stellantis, announced major U.S. Manufacturing investments in August, spanning semiconductors, automotive, biotech, and energy storage. The commitments total billions of dollars and are projected to create thousands of new jobs across multiple states.

SK hynix broke ground on an advanced packaging fabrication and R&D facility in West Lafayette, Indiana. The plant represents an investment estimated at over $4 billion. It will be built on a 133-acre site in the Purdue Research Park and will house a high-bandwidth-memory production line alongside an Advanced Packaging R&D Testbed. The company plans to start supplying next-generation HBM to U.S. Customers from this facility in the second half of 2029. The fab is expected to support about 1,000 employees when production begins. SK hynix cited Purdue University's track record of innovation, research excellence, and long-standing success in developing talent as a key reason for the Indiana location.

Automotive and Engine Manufacturing

Stellantis announced an additional $200 million investment in its Belvidere, Illinois, assembly plant, bringing its total commitment there to $800 million. The funds are a significant step toward restarting production of the Jeep Cherokee, which was idled in 2023. More than $60 million had already been spent through July on upgrades and assessments. The next-generation Cherokee will use Stellantis's new STLA One platform. Pilot production is targeted for 2028, with retail production following in 2029.

Innio plans to invest more than $300 million in its Waukesha, Wisconsin, campus. The expansion will create more than 500 jobs. Plans include new engine assembly capabilities and the construction of an advanced engine testing facility exceeding 80,000 square feet. Roger George, Innio’s Waukesha CEO, said the move highlights a commitment to local value creation in the United States. The company's engines power data centers and industrial operations across the country.

Energy and Biotech Expansions

DeltaX, a provider of battery energy storage systems, will spend $141 million to establish its North American manufacturing headquarters in Monroe, Georgia. Georgia Governor Brian Kemp stated the project will create about 250 jobs on a 25-acre site. The first phase involves a 100,000-square-foot assembly facility, with additional component manufacturing to follow. Kemp attributed the investment to the state's cutting-edge research universities, world-class workforce training, and reliable energy infrastructure.

Genentech will invest approximately $750 million to double the size of a device fill-finish manufacturing facility at its Hillsboro, Oregon, campus. The expansion is expected to create 250 manufacturing jobs and support 200 construction jobs, with commercial operations starting in 2031. The facility will manufacture prefilled syringes, autoinjectors, and other drug delivery devices.

Magnet Plant Financing Secured

Niron Magnetics received a $150 million loan from the Shakopee Mdewakanton Sioux Community to advance construction of a rare-earth-free permanent magnet plant in Sartell, Minnesota. This financing is in addition to a $150 million conditional commitment from the U.S. Department of Defense. The facility, slated to begin production in 2027, is expected to create about 175 full-time jobs. CEO Jonathan Rowntree said the loan helps accelerate construction and brings the company closer to establishing a domestic magnet source. Niron is also conducting final site selection for a subsequent U.S. Plant capable of producing 10,000 tons annually, with a planned 2028 groundbreaking.

The series of announcements follows other major manufacturing investments reported in August from companies like Micron and Rolls-Royce. Niron Magnetics is already planning its next U.S. Factory.
