Ethanol Marketing Agreement, dated April 16, 2025, by and between Green Plains Trade Group LLC and Eco-Energy, LLC (The exhibits to the Marketing Agreement have been omitted. The Company will furnish such exhibits to the SEC upon request.)

THIS ETHANOL MARKETING AGREEMENT (this “Agreement”), dated as of April 16th, 2025 (the “Execution Date”), is entered into by and between Eco-Energy, LLC, a Tennessee limited liability company with its registered office at 6100 Tower Circle, Suite 500, Franklin, Tennessee 37067 (“Eco”), and Green Plains Trade Group LLC, a company, with its principal office located at 1811 Aksarben Drive, Omaha, Nebraska 68106 (“GPTG”).

A.    GPTG operates multiple ethanol production facilities with addresses and individual site specifics as set forth in Exhibit A (the “Plants”) with a combined production capability of over 800 million gallons per year of commercially marketable ethanol (the “Output”) and desires to enter into a marketing agreement for the Output.

B.    Eco is an ethanol marketer and is experienced in the marketing, selling and the transportation of ethanol, and is willing to purchase and market the entire Output of the Plants and to supply Railcars (if necessary) to be used in the transportation of the Output.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, IT IS AGREED BETWEEN THE PARTIES:

1.Exclusivity:

(a)GPTG shall sell exclusively to Eco, and Eco shall purchase from GPTG, the entire Output of fuel grade ethanol, or other ethanol specification as agreed to by the parties, during the Term (as defined in Section 21(a)), on the terms set forth in this Agreement.

(b)In the event GPTG sells any ethanol to any person other than as permitted herein, Eco shall have all rights and remedies available at law or otherwise, including, without limitation, offsetting amounts that would have been payable to Eco for such ethanol against amounts owed by Eco to GPTG.

(c)Eco may purchase and otherwise market and sell ethanol and other products for Eco’s own use or account, and Eco may also market and sell ethanol and other products of other persons (including affiliates or related parties of Eco) as well as provide services to other persons, on such terms and conditions as are determined by Eco from time to time.

(a)Eco shall use commercially reasonable efforts to solicit competitive market offers for the ethanol purchased from GPTG. Eco shall use reasonable efforts to optimize freight, fuel characteristics, including but not limited to carbon intensity and related carbon items, and other marketing tools to provide competitive market pricing for GPTG’s ethanol production. Eco’s efforts shall include working with current, developing, and emerging markets to provide favorable ethanol pricing back to GPTG when compared with market alternatives. When commercially reasonable, Eco shall assist GPTG in determining if offers are competitive with alternative markets by providing market insight as part of the purchase offers or contracts.

(b)Eco shall use its commercially reasonable efforts to, from time to time, submit purchase orders or purchase contracts similar to Exhibit B (each, a “Purchase Order”) to GPTG for purchases of ethanol produced at the Plants, all upon and subject to the terms and conditions of this Agreement. Eco may place a Purchase Order with GPTG orally (if immediately followed by electronic communication (such as IM), by email or by a written Purchase Order in a form mutually acceptable to GPTG and Eco. The terms of any Purchase Order shall specify a purchase price F.O.B. the Plant (the “Purchase Price”) and shall specify the method of transport of the ethanol (i.e., via truck, rail or some combination thereof) and include a request for the sale and delivery of ethanol on a one-time basis or on a daily, weekly, monthly or other periodic basis. Any Purchase Order may be cancelled by Eco at any time, prior to the earlier of: (i) the time at which such Purchase Order becomes an Accepted Purchase Order (as that term is defined in Section 2(c) below) or (ii) prior to the time that GPTG has entered into a legally binding commitment based upon the Purchase Order.

(c)GPTG may accept or reject each Purchase Order in whole but not in part. GPTG shall notify Eco of GPTG’s acceptance or rejection of each particular Purchase Order within the time period specified in such Purchase Order, or if no time period is specified in such Purchase Order, within twenty-four (24) hours of GPTG’s receipt of such Purchase Order (in either case, the “Acceptance Period), and if GPTG fails to notify Eco within the Acceptance Period, GPTG shall be deemed to have rejected such Purchase Order. GPTG may accept or reject any Purchase Order orally (if immediately followed by electronic communication (such as IM), by e-mail or by written notice, provided, however, that Eco reserves the right to require GPTG to accept or reject any particular Purchase Order or Purchase Orders only in writing. Any Purchase Order that is accepted by GPTG is referred to in this Agreement as an “Accepted Purchase Order” and is binding on both parties and becomes incorporated into this Agreement. Thus, each Accepted Purchase Order becomes assimilated into this Agreement for purposes of determining the parties’ rights, duties, and/or liabilities. Notwithstanding any other term or condition of this Agreement or any Accepted Purchase Order, in the event of any inconsistency between the terms and conditions of this Agreement and any Accepted Purchase Order, this Agreement shall govern unless such Accepted Purchase Order expressly states its intent to supersede this Agreement and is in writing and signed by both Eco and GPTG. Eco shall summarize the terms of the Accepted Purchase Order in the form of a Purchase Contract (“Purchase Contract”).

(d)Each party shall designate one or more persons (each a “Representative”) who shall be authorized and directed to deal with the other party hereunder and to make all sales decisions on behalf of such party. All directions, transactions and authorizations given by such Representative(s) whether orally, electronically (including, without limitation, by email), by facsimile or in writing shall be binding upon the party that appointed the Representative. Both parties shall be entitled to rely on the authorization of the other party’s Representative(s) until it receives written notification from the other party that such authorization has been revoked and the name and contact information of the replacement representative(s).

(e)Notwithstanding anything contained in this Agreement to the contrary, if any portion of the Output is sold as fuel ethanol or another transportation fuel as identified in Section 45Z(d)(5) of Title 26 of the U.S. Code of Regulations, Eco is obligated to verify the volume is to be used by the end user buyer in the production of a fuel mixture, as a fuel in a trade or business, or sold at retail to another person and placed in the fuel tank for such person. Further, to remove any doubt, Eco is responsible for ensuring the sale meets the “qualified sale” requirements under Section 45Z and that the end user buyer does not resell or distribute any volume identified under Section 45Z(d)(5) of Title 26 of the U.S. Code of Regulations in bulk or use the volume as a primary feedstock to produce SAF or any other fuel that is eligible for U.S. federal tax credits. Additionally, if Section 45Z(d)(5) of Title 26 of the U.S. Code of Regulations is interpreted to require the producer (i.e., GPTG) to transact directly with the end user buyer to comply with the regulation, the parties will work together to amend this Section 2 to ensure regulatory compliance for the sale of such volume while keeping all other terms and conditions of this Agreement intact.

3.Railcar Lease & Fleet Management.

(a)Eco and GPTG will work together to determine the number of railcars needed by GPTG pursuant to this Agreement, which amount shall be agreed upon by each of Eco and GPTG. If additional railcars are determined to be necessary, Eco shall provide such railcars to GPTG at a market price and the parties will enter into a separate lease agreement specifying the number of railcars, lease term, fees, maintenance/repair responsibilities, etc. At any time during the Term, if it is determined by the parties that GPTG has more railcars than necessary in its overall fleet, Eco shall assist GPTG in subletting and/or developing a mitigation strategy to reduce the expenses related to the excess railcars.

(b)As part of its obligations under this Agreement, Eco will manage the entire railcar fleet assigned to each of the Plants by managing the movements to/from customer delivery locations, repair/maintenance shops, and/or storage locations. To ensure the efficient movement of each Plant’s railcar fleet, Eco will coordinate with applicable railroads, government regulators, delivery terminals and end users. Eco will also regularly communicate with GPTG on all aspects of the management of each Plants railcar fleet. Any costs attributed to the maintenance/repair of the Plants railcars, fines arising from loading violations, and/or other ancillary fees paid by Eco related to the Plants railcar fleet will be passed back to GPTG. Similarly, any demurrage charges collected by Eco on sales made on behalf of GPTG will be passed back to GPTG after Eco receives payment. Both parties acknowledge that GPTG has an existing railcar fleet, Eco shall mange the existing railcar fleet in the same manner as railcars provided by Eco.

4.Purchase Price and Fees:

(a)The amount payable by Eco to GPTG for ethanol that is purchased by Eco pursuant to this Agreement shall be the Purchase Price set forth in the applicable Accepted Purchase Order (the “Ethanol Fee”).

(b)The amount Payable by GPTG to Eco for services to be provided by Eco under this Agreement (the “Marketing Fee”) shall be equal to $[*] per gallon of ethanol.

(c)The per gallon Marketing Fee specified in Section 4(b) was devised based on the calendar year, annual Output exceeding 800 million gallons. The Parties agree that if during the Term for any reason (e.g., facility divesture, production idling, etc.) the annual volume marketed by Eco is reduced the Marketing Fee will be adjusted as follows:

(i)750,000,000–799,999,999 gallons    $[*] per shipped gallon;

(ii)700,000,000–749,999,999 gallons    $[*] per shipped gallon;

(iii)650,000,000–699,999,999 gallons    $[*] per shipped gallon;

(iv)600,000,000–649,999,999 gallons    $[*] per shipped gallon;

(v)550,000,000–599,999,999 gallons    $[*] per shipped gallon;

(vi)500,000,000–549,999,999 gallons    $[*] per shipped gallon;

(vii)450,000,000–499,999,999 gallons    $[*] per shipped gallon;

(viii)Under 449,999,999 gallons         $[*] per shipped gallon;

(d)For purposes of clarity, the Marketing Fee specified in Section 4(b) (i.e., $[*]) will be utilized for all invoicing intra-year. The total marketed volume will be calculated by Eco at the conclusion of each Term calendar year and, if applicable, a true up payment invoiced. For calendar year 2025, a pro rata percentage calculation will be made by calculating the number of days between the start of the Term and December 31, 2025, and then dividing this number by 365, minus 2.75% (to reflect the anticipated seasonal maintenance scheduled for 2025). As an example of the pro rata

calculation is as follows: If the term were to begin on April 1st, 2025, the pro rata adjustment to the volumes will be 72.32% (274/365 = 75.07% - 2.75%).

GPTG agrees to maintain at each Plant, in good and safe operating condition and repair and in accordance with all material respects with all applicable laws, rules and regulations, truck scales or metered pumps suitable for weighing/measuring ethanol. All reasonable costs and expenses incurred in connection with obtaining such certificates, and maintaining such truck weights, shall be borne by GPTG.

(b)If GPTG determines to expand the capacity of any Plant beyond its current Annual Production Capacity, GPTG shall give Eco written notice of such expansion and of the estimated monthly production of ethanol at the Plant after such expansion, as soon as reasonably possible. Eco shall purchase all of the additional ethanol to be produced, under the same terms as this Agreement, as a result of such expansion.

10.Quality of Ethanol:

(a)All ethanol sold to Eco hereunder shall meet all of the following specifications (the “Specifications”): (i) it shall be fuel grade, of consistent quality and composition, (ii) it shall meet the minimum quality standards set forth in Exhibit C (or any other grade or specification mutually agreed upon by the parties), (iii) it shall be of merchantable quality, stable and unadulterated, (iv) it shall be suitable for lawful introduction into commerce under the laws of the United States of America and any other nation to which the ethanol is shipped, and (v) it shall not change composition during or after loading.

(b)Notwithstanding any other term or condition of this Agreement, GPTG agrees and acknowledges that it will be solely responsible for the quality of the ethanol produced at the Plant while it is within GPTG’s control.

11.Rejection of Ethanol by Eco: Eco may reject, before or after delivery to Eco, any ethanol that fails to conform to or satisfy the requirements of Section 10. Eco shall provide GPTG written notice within forty-eight (48) hours of it receiving verification that any GPTG produced ethanol is being rejected under Section 10.

If any ethanol is properly rejected by Eco (the “Rejected Ethanol”), Eco will, in its discretion:

(a)Offer GPTG a reasonable opportunity to examine and take possession of the Rejected Ethanol, at GPTG’s cost and expense, if Eco reasonably determines that the condition of the Rejected Ethanol permits such examination and delivery prior to disposal;

(b)Dispose of the Rejected Ethanol in the manner as directed by GPTG, and at GPTG’s cost and expense, subject to the requirements of applicable laws, rules and regulations and any third-party rights; or

(c)If Eco has no reasonably available means of disposing of the Rejected Ethanol, and if GPTG fails to direct Eco to dispose of the Rejected Ethanol or directs Eco to dispose of the Rejected Ethanol in a manner inconsistent with applicable laws, rules or regulations or any third-party rights, then Eco may return the Rejected Ethanol to GPTG, at GPTG’s cost and expense.

Eco’s obligation with respect to any Rejected Ethanol shall be fulfilled upon GPTG taking possession of the Rejected Ethanol, the disposal of the Rejected Ethanol or the return of the Rejected Ethanol to GPTG, as the case may be, in accordance with subparagraphs (a), (b) or (c) above.

(e)Eco is now in compliance with all applicable federal, state, local and foreign laws, ordinances, orders, rules and regulations (collectively, “Laws”), other than Laws where neither the costs or potential costs of failing to comply, nor the costs or potential costs of causing compliance, would be material to Eco or its business or assets.

(b)    The parties enter this Agreement in reliance upon the Regulations in effect on the date of the Agreement with respect to or directly or indirectly affecting the ethanol to be delivered, including without limitation, production, gathering, manufacturing, transportation, sale and delivery thereof insofar as said Regulations affect the parties and their customers. In the event that at any time subsequent to the date of the Agreement, any of said Regulations are changed or new Regulations are promulgated whether by law, decree, interpretation or regulation, or by response to the insistence or request of any governmental authority or person purporting to act therefore, and the effect of such changed or new Regulation (i) is or will not be covered by any other provisions of the Agreement, or (ii) has or will have an adverse economic effect upon the parties to this Agreement or the suppliers or customers of said parties, the parties shall have the option to request renegotiation of the prices and other pertinent terms provided for in the Agreement and their respective effective dates.

29.Force Majeure: If any term or condition of this Agreement to be performed or observed by Eco or GPTG (other than a payment or indemnification obligation) is rendered impossible of performance or observance due to any force majeure event or any other act, omission, matter, circumstance, event or occurrence beyond the commercially reasonable control of Eco or GPTG, as the case may be (each, an “Force Majeure Event”), the affected party shall, for so long as such Force Majeure Event exists, be excused from such performance or observance, provided the affected party (i) promptly notifies the other party of the occurrence of the Force Majeure Event, (ii) takes all such steps as are reasonably necessary or appropriate to terminate, remedy or otherwise discontinue the effects of the Force Majeure Event, and (iii) recommences performance after the termination or discontinuance of the Force Majeure Event; provided, however, that if after thirty (30) days from the occurrence of the Force Majeure Event the affected party is still unable to perform its obligations under this Agreement, the other party may, in such party’s sole discretion, terminate this Agreement effective upon the giving of written notice to the affected party. The term “Force Majeure Event” includes an actual or threatened act or acts of war or terrorism, earthquake, acts of God including persistent weather conditions that materially affect the Plant’s ability to procure feedstock, receive shipments, ship ethanol, civil disturbance, hostilities, disorders, riots, sabotage, strikes, lockouts and labor disputes; provided, however, that nothing in this Section 29 is intended or shall be interpreted to require the resolution of labor disputes by acceding to the demands of labor when such course is inadvisable in the discretion of the party subject to such dispute. The term “Force Majeure Event” does not include (A) events affecting the performance of third-party suppliers of goods or services except to the extent caused by an event that otherwise is a Force Majeure Event; (B) changes to market conditions that affect the price of ethanol or other outputs of the Plant or corn or other feedstocks of the Plant that are not caused directly by a Force Majeure Event; (C) any obligation of either party to make payments

hereunder; or (D) any event caused solely or primarily by the acts or omissions of the party claiming a Force Majeure Event.

(b)Any arbitrator selected by mutual agreement of the parties shall be experienced in the matter or action that is the subject of the arbitration. The arbitrator so chosen shall be impartial and independent of both parties.

The decision of the arbitrator is binding and no suit at law or equity shall be instituted by any party to this agreement except to enforce the decision of the arbitrator.

Additionally, if this Agreement expires and/or is terminated for any reason and there are existing Purchase Contracts that have yet to be completed at the time of such expiration and/or termination these Purchase Contracts remain legally enforceable between the parties. Any amendment to this Agreement shall only be effective and binding if in writing and executed by the parties hereto.

(e)This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns.

(f)All issues, questions and disputes concerning the validity, interpretation, enforcement, performance or termination of this Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any other choice of law or conflict of laws rules or provisions.
