GPRE updates shelf registration with warrants, subscription and convertible notes

Rhea-AI Filing Summary

Amendment No. 2 to Green Plains Inc.'s Form S-3 updates the registration statement's exhibit list while leaving the prospectuses unchanged and omitted from this filing. The filing discloses an SEC registration fee of $53,437.27 and states that other issuance and distribution expenses cannot currently be estimated because they depend on the securities offered and the number of issuances. The company confirms indemnification protections in its Fifth Amended and Restated Bylaws, indemnification agreements with each officer and director, and D&O insurance; those agreements provide for advancement of legal expenses subject to Iowa law and list specific exceptions to indemnification. The exhibit list incorporates material transaction documents by reference, including asset purchase agreements and an Agreement and Plan of Merger, and adds multiple warrant agreements, a subscription agreement and convertible note indentures and related consents and legal opinions.

Positive

• Exhibit update adds multiple warrant agreements with institutional counterparties (Ancora and BlackRock series), increasing transparency about potential equity instruments.
• Incorporation by reference of convertible note indentures, including the 2.25% Convertible Senior Notes due 2027, clarifies existing debt-equity instruments in the capital structure.
• Subscription agreement and consents (KPMG, legal opinions) are included or filed, supporting readiness for offerings and audit/legal validations.

Negative

• Certain indemnification may be unenforceable as noted in the filing per the SEC’s expressed public policy regarding Exchange Act liabilities.
• Other issuance and distribution expenses cannot be estimated because they depend on the securities offered and number of issuances, leaving total offering costs undefined at this time.

Insights

Financial Analyst

TL;DR: Exhibit updates point to recent financing arrangements and refinements to the company’s capital structure.

The amendment is primarily administrative but materially useful to investors because it incorporates by reference financing and contractual arrangements that affect potential dilution and capital availability. Notable inclusions are multiple warrant agreements with institutional counterparties, a subscription agreement and the form and supplemental indentures related to the company’s 2.25% Convertible Senior Notes due 2027, which together indicate existing convertible instruments and pathways for equity issuance. The explicit SEC registration fee is $53,437.27, while other issuance costs are not estimable and will vary by offering size. Overall, this update increases transparency about available financing documents without altering prospectus terms.

Corporate Governance Expert

TL;DR: Indemnification provisions and D&O insurance are comprehensive but subject to legal limits noted in the filing.

The company’s bylaws and standalone indemnification agreements provide broad protections, including advancement of expenses and continuation beyond tenure, and require maintenance of D&O insurance. The filing explicitly notes that, in the SEC’s view, indemnification for certain liabilities under the Exchange Act is against public policy and may be unenforceable, and that indemnified persons may be required to repay advanced expenses if a court later finds they are not entitled to indemnification. The indemnification exceptions listed are detailed and include willful misconduct and settlements without company consent. These are standard but important governance disclosures that clarify limits on officer and director protections.

Item 15.   Indemnification of Directors and Officers.

The Company is an Iowa corporation. Our Fifth Amended and Restated Bylaws require us to indemnify directors and officers to the full extent permitted by the Iowa Business Corporation Act.

Under the Iowa Business Corporation Act, we must indemnify a director who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which the director was a party because the director is or was a director of the Company against reasonable expenses incurred by the director in connection with the proceeding. Further, under the Iowa Business Corporation Act, officers who are not directors, are afforded the same mandatory indemnification protections as directors upon successful application to the court. Additionally, we may indemnify our directors and officers where: (A)(i) the individual acted in good faith; (ii) the individual reasonably believed that (a) in the case of conduct in the individual’s official capacity, that the individual’s conduct was in the best interests of the corporation or (b) in all other cases, that the individual’s conduct was at least not opposed to the best interests of the corporation; and (iii) in the case of any criminal proceeding, the individual had no reasonable cause to believe the individual’s conduct was unlawful, or (B) the individual engaged in conduct for which broader indemnification has been made permissible or obligatory under a provision of the articles of incorporation.

We carry insurance policies insuring our directors and officers against certain liabilities that they may incur in their capacity as directors and officers.

We have entered into indemnification agreements with each of our officers and directors. Pursuant to the indemnification agreements, we are required to, among other things, indemnify each indemnitee against all expenses (including, attorneys’ fees, disbursements and retainers, accounting and witness fees and other disbursements and expenses) incurred in connection with certain proceedings that relate to the indemnitee’s service as an officer or director of the company. Further, we are required to indemnify for expenses incurred by the indemnitee in defense of a proceeding to the extent the indemnitee has been successful on the merits or otherwise. Finally, if the indemnitee is involved in certain proceedings as a result of the indemnitee’s serving as our officer or director, we are required to advance all expenses incurred by or on behalf of the indemnitee in connection with such proceeding, without regard to the indemnitee’s ability to repay the expenses and without regard to the indemnitee’s ultimate entitlement to indemnification under the other provisions of the indemnification agreement; provided, however, that to the extent required

II-1

​

by Iowa law, the indemnitee shall repay all the expenses paid to the indemnitee if it is finally determined that the indemnitee is not entitled to be indemnified.

The indemnification agreements contain certain exceptions to our obligation to indemnify. Among these exceptions, we are not obligated to make any indemnity in connection with any claim made against the indemnitee: (i) for which payment has actually been made to or on behalf of the indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provisions, (ii) for an accounting of profits made from the purchase and sale (or sale and purchase) by the indemnitee of securities of the company within the meaning of Section 16(b) of the Exchange Act, or similar provisions of state statutory law or common law; (iii) for which indemnitee settles a claim without our consent; (iv) for which such indemnitee is finally adjudged to have gained any person profit or advantage to which he or she was not legally entitled; (v) for which indemnitee’s conduct is finally adjudged to have been willful misconduct, knowingly fraudulent, deliberately dishonest or in violation of indemnitee’s duty of loyalty to us; (vi) for proceedings initiated or brought voluntarily by such indemnitee and not by way of defense, except with respect to proceedings brought to establish or enforce a right to indemnification under the applicable indemnification agreement or any other statute or law or otherwise as required by Iowa law; (vii) for which the indemnitee is indemnified by us otherwise than pursuant to the indemnification agreement; or (viii) for which a court of competent jurisdiction had made a final determination that indemnification under the indemnification agreement is unlawful.

The indemnification agreements also require us to obtain and maintain a policy or policies of insurance with a reputable insurance company providing the indemnitee with coverage for losses from wrongful acts and an indemnitee who is an officer or director shall be named as an insured.

All agreements and obligations of the company contained in the indemnification agreements shall continue during the period when the officer or director who is a party to an indemnification agreement is an officer or director of the company (or is serving at the request of the company as a director, officer, employee or other agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise) and shall continue thereafter so long as such director shall be subject to any possible claim or threatened, pending or completed action, suit or proceeding, whether civil, criminal, arbitrational, administrative or investigative. In addition, the indemnification agreements provide for partial indemnification and advance of expenses.

We have been advised that, in the opinion of the SEC, indemnification for certain liabilities is against public policy as expressed in the Exchange Act and is, therefore, unenforceable.

Item 17.   Undertakings.

(a)

The undersigned registrant hereby undertakes:

​

(1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

​

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act;

​

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 % change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

​

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

​

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

​

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

​

(4)

That, for the purpose of determining liability under the Securities Act to any purchaser:

​

(i)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

​

(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

​

II-6

​

(5)

That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

​

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

​

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

​

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

​

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

​

(6)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

​

(7)

Insofar as indemnification for liabilities arising under the Securities Act, as amended, may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

FAQ

What does Amendment No. 2 to Green Plains' (GPRE) Form S-3 do?

It updates the registration statement's exhibit list to add and incorporate by reference recent agreements and exhibits; the prospectuses themselves are unchanged and omitted from this amendment.

What fees does the filing disclose for the registration?

The filing discloses an SEC registration fee of $53,437.27 and states that other fees (FINRA, legal, accounting, printing, transfer agent, miscellaneous) are dependent on the securities offered and cannot be estimated at this time.

Which material agreements were added or referenced in the exhibits for GPRE?

The exhibits incorporate asset purchase agreements and an Agreement and Plan of Merger by reference and add multiple warrant agreements (Ancora and BlackRock series), a subscription agreement, and forms/indentures related to the 2.25% Convertible Senior Notes due 2027, plus related legal opinions and consents.

Does the filing address indemnification for directors and officers at Green Plains (GPRE)?

Yes. The Fifth Amended and Restated Bylaws and separate indemnification agreements require indemnification to the fullest extent permitted by Iowa law, provide for advancement of expenses subject to repayment if not entitled, list specific exceptions, and note D&O insurance coverage.

Are there any auditor or legal consents included in the amendment for GPRE?

Yes. The exhibit list includes the consent of KPMG LLP and legal opinions from Husch Blackwell LLP regarding the legality of the registered securities (some exhibits previously filed and some filed herewith).
