Hertha Metals raised $134 million in a Series A round with the Defense Department taking a $65 million equity stake to fund construction of a new facility producing high-purity iron for rare earth magnets. The investment addresses a critical vulnerability in the defense supply chain.
What's happening
- Hertha Metals closed $134 million Series A led by Khosla Ventures and Doerr Capital with DoD contributing $65 million equity.
- Proceeds will fund construction of a domestic facility producing high-purity iron used in most rare earth magnets.
- DoD made the investment through its Industrial Base Analysis and Sustainment program in partnership with the Economic Defense Unit.
Why it matters
- Rare earth magnets are essential components in defense systems but depend on vulnerable international supply chains.
- High-purity iron production domestically reduces reliance on foreign sources and strengthens the critical materials supply base.
- DoD equity stake aligns financial incentives with production capacity and supply security for weapons systems.
Financial impact
- DoD receives equity ownership stake of approximately 49 percent based on $65M investment of $134M total Series A.
- Cash enters balance sheet in Q3 2026 and capital expenditure for facility construction begins immediately.
- Revenue recognition depends on facility completion timeline and ramp; timing not disclosed.
The fine print
- DoD equity stake terms, governance rights, and liquidation preferences not disclosed.
- Facility construction timeline and production capacity targets not specified in available reporting.
- Economic Defense Unit partnership scope and any additional government support mechanisms undefined.
