Amendment No. 7 to Schedule 13D

Pursuant to this Amendment, the items identified below, or the particular paragraphs of such items which are identified below, are amended as set forth below.

Item 2.Identity and Background.

The Reporting Persons hereby restate the disclosures contained in Item 2 of the Schedule 13D, which are hereby incorporated by reference. The disclosure in Item 2 is hereby amended as follows:

Pursuant to the Merger Agreement (as defined below), Granite Falls Energy, LLC expects the funding for the Merger (as defined below) described in Item 4 of this Amendment No. 7 (which Item 4 is incorporated herein by reference) will consist of a combination of a long-term revolving loan and a term note from Granite Falls Energy, LLC’s lender as described in Item 4.

Item 4.Purpose of Transaction.

The Reporting Persons hereby restate the disclosures contained in Item 4 of the Schedule 13D, which are hereby incorporated by reference. The disclosure in Item 4 is hereby supplemented by adding the following at the end thereof:

Merger Agreement

On March 24, 2021, the Issuer entered into a Merger Agreement and Plan of Merger (the “Merger Agreement”) with Granite Falls Energy, LLC, a Minnesota limited liability company (“GFE”), and Granite Heron Merger Sub, LLC, a Minnesota limited liability company and a wholly owned subsidiary of GFE (“Merger Sub”),

pursuant to which Merger Sub will merge with and into the Issuer, with the Issuer surviving as a wholly owned subsidiary of GFE (the “Merger”).

The primary purpose of this transaction is to maximize our members’ return on their investments in the Company and reduce the risk that the Company will be forced to cease operations or seek bankruptcy protection due to potential loan covenant violations. The Company experienced significant net losses during the past year due to several factors, including elevated corn prices, the breakdown of our ethanol plant’s boiler, and reduced demand for ethanol due to the COVID-19 pandemic. Due to these net losses, the Company has violated certain loan covenants related to working capital and net worth ratio, for which the Company has obtained waivers from its lender. The Company was in violation of such loan covenants as of October 31, 2020, and January 31, 2021. As a result of these loan covenant violations, the Company’s auditor reported that as of January 31, 2021, there was substantial doubt about the Company’s ability to continue operating as a going concern. Due to improved market conditions and operating efficiency, Company was in compliance with its debt covenants on April 30, 2021. However, it possible that the Company will incur future instances of loan covenant violations and it is possible that the Company’s lender will not provide a waiver for such violations. Future loan covenant violations would allow the Company’s lender to accelerate certain loans and designate a substantial portion of the Company’s debt due and payable. If the Company’s loans became due and payable, there is a substantial risk the Company would lack the cash on hand, borrowing capacity, and cash flows to repay the debt, and if this were to occur, the Company could be forced to cease operations or seek bankruptcy protection. If the Company were forced to cease operations or seek bankruptcy protection, our members could lose all or a substantial portion of their investment in the Company.

GFE currently owns approximately 50.65% of the Issuer’s units. Under the terms of the Merger Agreement, at the effective time of the Merger, GFE will acquire the remainder of the units (the “Minority Ownership Interest”), which comprises of 38,456,283 Class A units. The purchase price for the entire Minority Ownership Interest is $14,000,000.00 in cash payable at the closing of the Merger. Each issued and outstanding unit of the Minority Ownership Interest will be canceled and converted into the right to receive $0.36405 per unit. (the “Merger Consideration”). The units of the Issuer held by GFE immediately prior closing of Merger shall be cancelled with no consideration issued to GFE. GFE will emerge from the transaction as the sole owner of the Issuer. As the sole owner of the Issuer, GFE may eliminate the Issuer’s board of governors altogether, and directly manage the Issuer.

Upon closing of the Merger, the Issuer intends to file a Certification and Notice of Termination of Registration with the SEC, which will allow the Issuer to operate without its securities being registered under the Securities Exchange Act of 1934, as amended. Upon termination of the Issuer’s SEC registration, the Issuer will no longer be required to file quarterly and annual reports with the SEC. GFE, which will become the Issuer’s sole owner upon closing of the Merger, will continue to be registered with the SEC and will continue to file required SEC reports after completion of the Merger.

GFE expects to finance the Merger with a loan from its lender, which GFE expects will include a long-term revolving loan and a term note. The terms and conditions of a loan agreement to finance the Merger have not been agreed upon. Completion of the Merger is subject to GFE’s receipt of cash proceeds to finance the Merger on terms satisfactory to GFE.

The Merger Agreement contains customary representations and warranties from the parties, and each party has agreed to customary covenants, including, among others, covenants relating to (i) the conduct of business during the interim period between the execution of the Merger Agreement and the effective time of the Merger and (ii) the obligation to use reasonable best efforts to cause the Merger to be consummated.

Completion of the Merger is subject to certain conditions, including, among others: (i) approval of the Merger by a majority in interest of the Minority Ownership Interest at a special meeting of the Issuer’s members; (ii) consent of GFE’s and Issuer’s lender; (iii) GFE’s receipt of cash proceeds from financing transactions to finance the Merger on terms satisfactory to GFE; (iv) GFE’s receipt of an opinion by its tax advisor that the structure of the Merger has no materially adverse tax consequences to GFE; (v) the receipt of regulatory approval on terms reasonably satisfactory to GFE; and (vi) the receipt of any third-party consents required to consummate the Merger.

The Merger Agreement provides for certain termination rights for both GFE and the Issuer, including in the event that (i) the Merger is not approved by the majority in interest of the Minority Ownership Interest at the special member meeting, (ii) the Merger is not consummated by 5:00 p.m. CT on July 31, 2021 due solely to either lack of regulatory or lender consent, or (iii) GFE and Issuer mutually agree to terminate the Merger Agreement.

Pursuant to the Merger Agreement, GFE and Issuer release, acquit, and discharge each other and all related parties from all claims, including, all liabilities, obligations, claims, litigation, actions, causes of action, suits, proceedings, executions, judgments, demands, damages, losses, duties, debts, dues, accounts, fees, costs, expenses and penalties, and agree not to initiate, maintain, prosecute or continue to maintain or prosecute any action, suit or proceeding, or seek to enforce any right or claim against the other or its related parties.

Pursuant to the Merger Agreement, the Issuer and GFE intend but are not required to complete the Merger within five (5) business days of the of the members of the Issuer voting to adopt the Merger Agreement, subject to the receipt of regulatory approval. The exact closing date has not been set and may change depending on the ability to obtain regulatory approval and other factors.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is filed as Exhibit P to this Amendment No. 7 and incorporated herein by reference into this Item 4. The Merger Agreement is incorporated herein by reference to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual or financial information about GFE, the Issuer, the other parties to the Merger Agreement or any of their respective subsidiaries and affiliates. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of that agreement and as of specific dates; were solely for the benefit of the parties to the Merger Agreement; may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of GFE, the Issuer, the other parties to the Merger Agreement or any of their respective subsidiaries and affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures by GFE and the Issuer. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the companies and the Merger that will be contained in, or incorporated by reference into, the information statement/prospectus that the parties will be filing in connection with the Merger, as well as in the other filings that each of GFE and the Issuer make with the SEC.

Governors Voting Agreement

On March 24, 2021, concurrent with the execution of the Merger Agreement, GFE and the governors of the Issuer elected by the Minority Ownership Interest (the “Minority Interest Governors”) executed a voting agreement (the “Governors Voting Agreement”). The Issuer’s Minority Interest Governors included Mike Kunerth, Doug Schmitz, Dave Woestehoff, and Robert Ferguson. The execution of the Governors Voting Agreement was a condition of the Issuer’s willingness to enter into the Merger Agreement.

Pursuant to the Governors Voting Agreement, the Minority Interest Governors agreed to vote all of their units in favor of approving the Merger Agreement and any transactions contemplated thereby, and agreed to vote all their units and against any proposal, transaction or agreement that could impede, interfere with, delay, discourage, adversely affect, or inhibit the timely consummation of the Merger. The Minority Interest Governors agreed to recommend the members of the Issuer vote in favor of the Merger Agreement and any transactions contemplated thereby, and against any proposals, transactions, or agreements to the contrary. Further, the Minority Interest Governors agreed appoint the Issuer and any designee of the Issuer as their proxy for the purposes of voting on the proposed Merger agreement and to revoke all prior proxies.

Additionally, pursuant to the Governors Voting Agreement, the Minority Interest Governors agreed that during the term of said agreement they will not directly or indirectly, transfer, sell, offer, exchange, assign, pledge, convey any legal or Beneficial Ownership interest in or otherwise dispose of any units of the Issuer.

The foregoing summary describes the material provisions of the Governors Voting Agreement. The descriptions of the Governors Voting Agreement in this summary are not complete and are qualified in its entirety by reference to the full text of the Governors Voting Agreement, a copy of which is filed as Exhibit R to this Amendment No. 7 and incorporated herein by reference into this Item 4.

Capitalized terms in this section but not defined in this Item have the meaning ascribed to such terms in the Governors Voting Agreement.

GFE Voting Agreement

On March 24, 2021, concurrent with the execution of the Merger Agreement, GFE and Issuer executed a voting agreement (the “GFE Voting Agreement”). The execution of the GFE Voting Agreement was a condition of the Issuer’s willingness to enter into the Merger Agreement.
