MINNEAPOLIS, Aug. 7, 2026 /PRNewswire/ — Niron Magnetics, the company commercializing the world’s first rare-earth-free Iron Nitride permanent magnets, today announced a conditional commitment from the Department of War’s Office of Strategic Capital (OSC) for a direct loan of up to $150 million with a 20-year term to support construction and equipment for the company’s advanced manufacturing plant in Sartell, Minnesota. The financing would accelerate domestic production of Niron’s proprietary Iron Nitride permanent magnets, which do not require rare earth materials, and would expand domestic production of advanced permanent magnets.

Today's financing would accelerate domestic production of Niron's proprietary Iron Nitride permanent magnets, which do not require rare earth materials, and would expand domestic production of advanced permanent magnets.

The Niron conditional commitment was announced by President Donald J. Trump at the American Mining Industry gathering in Washington D.C.

The conditional commitment reflects the federal government’s growing focus on securing domestic production of high-performance permanent magnets. The conditional commitment is intended to advance Niron’s commercialization and scaling of powerful, rare-earth-free Iron Nitride magnets.

Iron Nitride technology was developed at the University of Minnesota and scaled over the last 13 years, resulting in technology that provides manufacturers with a sought-after alternative to rare earth magnets.

Permanent magnets are essential components in defense systems, data centers, industrial automation, consumer electronics, robotics, aerospace applications, and advanced electric motors. Today, most rare earth permanent magnets are produced overseas, creating strategic vulnerabilities for U.S. manufacturers.

Niron’s rare-earth-free magnets adopt a different approach. Niron’s supply chain has no rare earth materials, offshore separation, or heavy rare earth exposure. Rather than reshoring a rare earth supply chain, Niron’s magnets are made without rare earth materials, instead making use of abundant, domestically sourced iron and nitrogen feedstocks. The result is a high-performance permanent magnet technology designed to improve materials security while reducing exposure to foreign export controls and rare earth price volatility.

“Permanent magnets are foundational to the technologies driving America’s economic competitiveness and national security,” said Jonathan Rowntree, CEO of Niron Magnetics. “This conditional commitment recognizes the importance of Niron’s rare-earth-free approach and the urgency of building domestic manufacturing capacity for a technology the world increasingly depends on. We are accelerating commercialization of an American-developed magnet technology that offers manufacturers a domestic path to high-performance permanent magnets built without rare earth materials.”

“Niron Magnetics is helping Minnesota lead the way in manufacturing to support our national security,” said Congressman Tom Emmer. “This conditional commitment from the Office of Strategic Capital will help Niron create approximately 175 high-quality jobs in Sartell, helping Minnesota’s economy grow and thrive. It’s great to see companies in our own backyard powering our economy and supporting our military.”

The conditional financing is intended to accelerate the buildout of Niron’s first commercial-scale rare-earth-free permanent magnet manufacturing plant scheduled to be operational in 2027. The 287,000-square-foot Sartell plant would bring material-to-magnet production under one roof and produce up to 1,500 tons of rare-earth-free permanent magnets annually. The plant is the first step in Niron’s modular manufacturing platform, with final site selection underway for a subsequent U.S. manufacturing plant capable of producing 10,000 tons of annual capacity that is expected to break ground in 2028.

Building on Niron’s proprietary manufacturing platform, the OSC financing is intended to:

Expand domestic manufacturing capacity for high-performance permanent magnets made without rare earth materials
Strengthen the U.S. industrial base for critical industries, including AI infrastructure, defense, automotive, industrial automation, aerospace and energy
Accelerate commercialization of American-developed magnet technology while creating high-quality manufacturing jobs in Minnesota

The OSC conditional commitment builds on Niron’s continued progress in advancing domestic magnet manufacturing as global demand for permanent magnets is projected to grow from approximately 280,000 tons today to more than 600,000 tons by 2035. As demand accelerates across AI infrastructure, electrification, industrial automation and advanced defense systems, Niron’s rare-earth-free technology offers manufacturers a domestic path to high-performance magnets without increasing dependence on constrained rare earth materials.

The OSC conditional commitment reflects a broader national effort to expand domestic production capacity for technologies essential to U.S. economic and national security. For Niron, the conditional commitment advances a manufacturing platform designed to reduce reliance on rare earth materials while supporting a more secure U.S. industrial base.

The conditional commitment between OSC and Niron Magnetics remains subject to additional requirements before the execution of definitive financing documents, including, without limitation, OSC’s completion of due diligence to its satisfaction, Niron’s receipt of a specified minimum amount of equity, and certain other conditions set forth in the commitment letter.

Wiley Rein LLP acted as legal advisor, and Morgan Stanley & Co. LLC acted as the sole financial advisor to Niron Magnetics on this transaction.
