Department of Energy Loan Programs Office (the “DOE LPO”) to guarantee a $1.46 billion (excluding $167 million in capitalized interest during construction) loan for its ATJ-60 synthetic aviation fuel project (formerly known as Net-Zero 1) in Lake Preston, South Dakota. On October 8, 2025, the company received a letter from the DOE LPO granting an extension of the Conditional Commitment until April 16, 2026 (the “Extension”). The Extension allows the Company and DOE LPO to evaluate certain potential modifications to the project scope under the Conditional Commitment in order to address energy policies and priorities. The Conditional Commitment will remain effective during the extension period in order to allow for modifications which satisfy the DOE LPO. The potential scope modifications include the construction of a lower cost 30 million gallon per year jet fuel production facility (“ATJ-30”) to develop jet fuel production at the Company's existing ethanol and carbon capture utilization and storage facility in North Dakota and the optimal use of captured carbon dioxide for enhanced oil recovery.

The Stifel Agreement became effective on the Stifel Agreement Effective Date and will continue in full force and effect unless terminated by any Party pursuant to the terms of the Stifel Agreement. The Parties may terminate the Stifel Agreement if certain customary events of default occur and are not cured within a certain time period. The Parties may also terminate the Stifel Agreement if there is a retroactive change in tax law that is reasonably likely to limit, restrict, reduce or disallow the transferred credits or the transfer thereof or creates a reasonable likelihood that the transferred credits will not be allowed or will be lost, disallowed or reduced. Upon the termination of the Stifel Agreement, Transferor shall refund to Stifel Transferee all amounts previously paid by Stifel Transferee to Transferor with respect to transferred Credits that Stifel Transferee is unable to claim as a result of such termination, plus interest (or in the case of a retroactive change in tax law, Transferor shall repay Stifel Transferee those amounts paid by Stifel Transferee to Transferor attributable to transferred credits that Transferor is unable to transfer or of that Stifel Transferee is unable to claim as a direct result of such change in tax law, plus interest).

The Stifel Agreement contains certain customary representations, warranties, covenants and confidentiality provisions, and also contains indemnification obligations by Transferor.

Under the CC Agreement, Transferor expects to deliver $10.0 million of Credits to CC Transferee between November 4, 2025 and February 28, 2026 upon satisfaction of certain conditions precedent on each transfer date, with $5.0 million of such Credits being transferred as of the CC Agreement Effective Date.

The CC Agreement became effective on the CC Agreement Effective Date and contains certain customary representations, warranties, covenants and confidentiality provisions, and also contains indemnification obligations by Transferor.
