U.S. manufacturers kept up the momentum (and then some) in March 2025, with massive new investments announced across numerous sectors. Encompassing mega-investments from industrial giants such as G.E. Aerospace, Johnson & Johnson, and TSMC to surging investments in electrical and energy infrastructure, it was a big month for U.S. manufacturing to say the least. Spanning multiple states and representing thousands of new jobs, here are the most exciting new operations announced in March.
New U.S. Manufacturing Operations Announced: March 2025
First up, continuing the domestic investment trend set by the likes of Apple and pharma giant Lily in February, several corporations have announced similar “mega-investments” this month. Let’s take a look.
Multi-State Investments
Johnson & Johnson Increases U.S. Investment to Over $55 Billion
Johnson & Johnson announced a significant increase in its U.S. investment, committing more than $55 billion over the next four years. This investment includes the construction of four new manufacturing facilities, starting with a groundbreaking on a $2 billion+ facility in Wilson, North Carolina. The new 500,000-square-foot biologics manufacturing facility will create over 500 jobs in North Carolina and support approximately 5,000 jobs during construction. “Today’s announcements accelerate our nearly 140-year legacy as an American innovation engine tackling the world’s toughest healthcare challenges,” said Joaquin Duato, Chairman and Chief Executive Officer, Johnson & Johnson. The company’s increased investment will also expand its R&D infrastructure and enhance technology investments to support drug discovery and development.
TSMC Expands U.S. Investment to $165 Billion for AI Advancements
Also in March, Taiwan Semiconductor Manufacturing Company announced to much fanfare an additional $100 billion investment in its U.S. advanced semiconductor manufacturing operations, bringing the total to $165 billion. This expansion includes three new fabrication plants, two advanced packaging facilities, and a major R&D center, making it the largest single foreign direct investment in U.S. history. The project is expected to support 40,000 construction jobs over the next four years and create tens of thousands of high-paying, high-tech jobs in advanced chip manufacturing and R&D. “With the success of our first fab in Arizona, along with needed government support and strong customer partnerships, we intend to expand our U.S. semiconductor manufacturing investment by an additional $100 billion,” said TSMC Chairman and CEO Dr. C.C. Wei. This expansion aims to strengthen the U.S. semiconductor ecosystem and support leading AI and technology innovation companies.
Clarios Announces $6 Billion American Energy Manufacturing Strategy
Clarios has unveiled a $6 billion plan to expand U.S. manufacturing and accelerate American innovation, emphasizing energy and critical mineral independence. The strategy includes expanding existing operations, building new facilities, and creating American jobs, supported by federal advanced manufacturing tax credits. “Now more than ever, America must protect its critical minerals and invest in technology essential to energy independence,” said Clarios CEO Mark Wallace. The plan outlines significant investments in advanced battery production, critical minerals processing and recovery, next-generation technologies, and state-of-the-art manufacturing, with the goal of enhancing the nation’s critical supply of starter batteries.
GE Aerospace to Invest Nearly $1 Billion in U.S. Manufacturing in 2025
GE Aerospace has announced plans to invest nearly $1 billion in its U.S. factories and supply chain to strengthen manufacturing and increase the use of innovative new parts and materials needed for the future of flight. This investment will help increase engine safety, quality, and delivery, benefiting more than two dozen communities across 16 states. The company also announced it will hire around 5,000 U.S. workers this year, including both manufacturing and engineering roles. “Investing in manufacturing and innovation is more critical than ever for the future of our industry and the communities where we operate,” said H. Lawrence Culp, Jr., Chairman and CEO of GE Aerospace.
Meanwhile, new facility announcements were emerging across the U.S., driven by strong investment in energy infrastructure, electrical equipment, food processing, and more. Here are some key highlights:
