Rivian Automotive, Inc. (Sponsor) and its subsidiary Rivian New Horizon, LLC (Borrower) entered into an Amended and Restated Loan Arrangement and Reimbursement and Sponsor Support Agreement (A&R LARSSA) with the U.S. Department of Energy (DOE) on April 30, 2026. This agreement amends an original loan arrangement from January 16, 2025, providing significant funding for the first phase of a new electric vehicle manufacturing facility in Stanton Springs North, Georgia. The facility is designed for an annual production capacity of 300,000 electric vehicles, primarily Rivian's R2 and R3 models. The amended facility comprises two tranches: Note A Loan of up to $3,355,410,861.67 in principal plus up to $315,352,641.39 in capitalized interest (approx. 15-year term), and Note B Loan of up to $650,902,306.53 in principal plus up to $178,334,190.41 in capitalized interest (approx. 10-year term). Total potential funding from the DOE loan program is approximately $4.006 billion in principal and $493.68 million in capitalized interest, with an overall maximum loan amount of $4.5 billion. Advances under the loan are subject to various conditions, including the Sponsor maintaining positive gross margin for certain periods, achieving specific vehicle sales metrics, making required base equity contributions, and granting security over Project assets to the DOE. The Sponsor and certain material domestic subsidiaries will jointly and severally guarantee the Borrower's obligations under the loan. The interest rate for the DOE loan is tied to the U.S. Treasury-equivalent yield curve with a 0% credit spread, set at each advance.
