What Metamagnetics does

Metamagnetics Inc. (METAMAG) is a veteran-owned, privately held U.S. defense technology company headquartered in Marlborough, Massachusetts. Founded in 2009, the company develops electromagnetic metamaterials and RF/microwave products designed to enhance the performance of radar, communication, and power supply systems for defense and aerospace applications.

The company's core technology centers on electromagnetic metamaterials applied to mission-critical RF subsystems, structured around a vertically integrated "powder-to-product" platform that spans critical materials recovery, magnetic passive components, and RF system performance. In May 2026, Metamagnetics acquired Lanthanide Solutions Inc. (LSI) as a wholly owned subsidiary, adding a proprietary circular-economy model for recovering high-purity rare earth elements from defense-cleared end-of-life scrap. This capability is positioned to address U.S. national security vulnerabilities tied to China's near-monopoly (~90%) of global rare earth refining.

Metamagnetics generates revenue primarily through hardware sales of RF and metamaterial products to U.S. defense programs and aerospace contractors via direct enterprise field sales. The customer base is concentrated in the defense and aerospace vertical, with secondary expansion plans into clean energy, electric vehicles, and advanced electronics. Pricing is not publicly disclosed and operates through quote-based defense procurement. Cumulative disclosed funding is approximately $2 million since 2015, drawn from MassVentures and undisclosed investors via SEC Form D exempt offerings.

Core offering

Metamagnetics develops and manufactures electromagnetic metamaterial and RF/microwave products that enhance the performance of radar, communication, and power supply systems for defense and aerospace customers. The company operates a vertically integrated 'powder-to-product' platform that combines proprietary rare earth element (REE) recovery from defense-cleared end-of-life scrap with magnetic passive component manufacturing and RF system design. It sells these components, subsystems, and recovered rare-earth materials directly to U.S. defense programs and aerospace contractors.

Product overview

Metamagnetics Inc. (METAMAG) is a veteran-owned defense technology company based in Marlborough, Massachusetts, specializing in electromagnetic metamaterials for defense applications. The company operates a 'powder-to-product' platform spanning critical materials recovery, magnetic passive components, and RF system performance. As of 2026, the company has integrated Lanthanide Solutions Inc. (LSI) as a wholly owned subsidiary to establish a fully domestic, vertically integrated supply chain for rare earth elements essential to modern defense systems. This vertical integration enables the company to recover high-purity REEs from defense-cleared end-of-life scrap, creating a circular economy model that bypasses foreign dominance in rare earth mining, refining, and magnet production. The combined organization serves defense and aerospace markets with plans to expand into clean energy, electric vehicles, and advanced electronics sectors. Specific product names and individual product offerings are not detailed in the available source material.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Echodyne: Echodyne develops metamaterial-based electronically scanned radar systems for defense, security, and autonomous applications. It is the closest direct peer to Metamagnetics in commercializing metamaterial technology for radar and detection markets.
• Pivotal Commware: Pivotal Commware builds metamaterial-based beamforming and communications products. It is comparable to Metamagnetics as a peer developing metamaterial RF components for communications and defense use cases.
• Fractal Antenna Systems: Fractal Antenna Systems develops fractal and metamaterial antennas for defense and commercial markets. It shares Metamagnetics' focus on novel electromagnetic antenna and RF component architectures.

Broad incumbents

• MP Materials: MP Materials operates the largest U.S. rare earth mine and processing facility. It is comparable to Metamagnetics' REE supply chain ambitions but at substantially greater scale and with a primary focus on mining and refining rather than scrap recovery.
• Lynas Rare Earths: Lynas Rare Earths is the largest non-China rare earth processor globally, supplying separated REEs to commercial and defense customers. It is comparable to Metamagnetics' REE recovery activity but operates at industrial scale.
• Qorvo: Qorvo is a major RF semiconductor supplier with a substantial defense and aerospace business. It is comparable to Metamagnetics' RF system performance focus but operates at far greater scale across commercial and defense markets.
• Mercury Systems: Mercury Systems designs and manufactures mission-critical defense electronics, including RF and microwave subsystems. It is comparable to Metamagnetics' defense RF component and subsystem business but serves a much broader portfolio.
• Cobham Advanced Electronic Solutions: Cobham AES (now part of TransDigm) supplies RF, microwave, and electronic warfare subsystems to defense customers. It overlaps with Metamagnetics' radar, communications, and electronic protection applications.
• Raytheon (RTX): Raytheon, part of RTX, is a leading defense prime integrating advanced radar, communications, and electronic warfare systems. It is comparable to Metamagnetics as a downstream customer and systems integrator for defense RF and metamaterial content.

Emerging players

• USA Rare Earth: USA Rare Earth is developing domestic rare earth mining and processing capacity. It competes in the same 'domestic REE supply' narrative as Metamagnetics but is at an earlier commercialization stage and focused on primary mining rather than scrap recovery.
