Item 1.01. Entry into a Material Definitive Agreement.
On October 29, 2026 (the “Execution Date”), Green Plains Inc. (“Seller” and the “Company”), entered into a Tax Credit Purchase Agreement (the “Agreement”) with two unaffiliated parties (“Buyers” and, together with Seller, the “Parties” and, each, a “Party”), pursuant to which Seller agreed to supply production tax credits available under Section 45Z to Buyers from the production of Seller’s ethanol at its operating facilities between January 1, 2026 and December 31, 2026 (the “Production Year”). Under the Agreement, Seller has committed to deliver, and Buyers have committed to purchase, a minimum of $250 million of Section 45Z credits, up to a maximum of $325 million in the aggregate, subject to generation and availability and the satisfaction of certain conditions. The confidential purchase price, which includes a market-based discount for such credits, is payable on each confirmation date against delivery of the corresponding credits, with cash proceeds associated with the first half of 2026 credit generation expected during the fourth quarter and proceeds associated with third and fourth quarters credit generation and any final true-up amounts expected in the first half of 2027.
The Buyers consist of two unaffiliated institutional counterparties: (i) a leading U.S. life insurance company that will acquire up to $5 million of transfer credits in the final funding tranche, and (ii) an investment subsidiary of a Fortune-ranked engineering and construction company that will acquire the balance, with that subsidiary's payment obligations unconditionally guaranteed by its ultimate parent (a direct, primary-obligor guaranty). Payment of the purchase price for each tranche is made on the applicable confirmation date against delivery of the corresponding transfer credits; each Buyer has represented that it will have sufficient cash on hand or access to immediately available funds to make each such payment; and the Company has received the most recent audited financial statements of the primary insurance-company Buyer and of the parent guarantor.
The Agreement became effective on the Execution Date and will continue in full force and effect unless terminated by a Party. The Parties may terminate the Agreement if certain customary events of default occur and are not cured within a certain time period. In addition, if a change or proposed change in tax law limits, restricts, reduces, or disallows any portion of the transferred credits, Seller's ability to transfer such credits, or any Buyer's ability to claim or utilize such credits, Seller is obligated to return to the affected Buyer the portion of the purchase price attributable to the affected credits (together with interest), the parties' rights and obligations with respect to such affected credits terminate, and the Agreement otherwise continues in effect with respect to any unaffected credits. The Agreement contains certain customary representations, warranties, covenants, confidentiality, and indemnity provisions.
The foregoing description of the terms of the Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the form of the Agreement, a copy of which is attached hereto as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
Item 7.01. Regulation FD Disclosure.
On October 30, 2026, the Company issued a press release announcing the agreement to sell production tax credits. A copy of the press release is furnished hereto as Exhibit 99.1 and incorporated into this Item 7.01 by reference.
The information in this Item 7.01 of Form 8-K, including the accompanying Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liability of such section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of the general incorporation language of such filing, except as shall be expressly set forth by specific reference in such filing.
