Form Energy
Led by Barclays
Form Energy closed a $270 million credit facility on September 21, 2026. The package combines a revolving credit facility with an advance against Section 45X manufacturing tax credits.
An accordion can expand total credit under the facility to $1 billion. That is potential capacity, not the amount currently closed.
Facility terms
| Field | Detail |
|---|---|
| Company | Form Energy |
| Closed facility | $270M |
| Components | Revolver; Section 45X tax-credit advance |
| Potential capacity | Up to $1B through an accordion |
| Structuring bank | Barclays |
| Other lenders | Citi; Jefferies; JPMorgan; RBC; Société Générale; Stifel; Wells Fargo |
| Type | Debt, not equity |
Why this financing matters
Form is scaling an iron-air battery designed for multi-day grid storage. Manufacturing expansion and working capital can consume cash well before customer projects generate payment, making debt availability an important complement to venture equity.
The tax-credit advance is particularly notable: it converts expected federal manufacturing credits into near-term liquidity. That links the facility directly to output at Form Factory 1 in Weirton, West Virginia.
Keep the capital stack separate
The debt follows Form's $750 million Series G, which closed in August and took total equity raised above $2 billion. The $270 million facility is not an extension of that round, and the $1 billion accordion is not funded capital today.
Bottom line
The confirmed close is $270 million of debt. The facility could grow to $1 billion if additional capacity is activated, but the headline should preserve the difference between closed credit and future borrowing availability.
