GEVO, INC._December 31, 2024
 0001392380FYtrueP1YP1YP1YP1YP1YP1YP1YP1YP1YP1YP1YP1YP1YP1YGevo, Inc. (the "Company") is filing this Amendment No. 1 on Form 10-K/A (this "Amendment") to its Annual Report on Form 10-K for the year ended December 31, 2024, which was originally filed with the Securities and Exchange Commission (the "SEC") on March 27, 2025 (the "Original Filing"). This Amendment is being filed solely to amend Part II "Item 9B. Other Information" by adding Rule 10b5-1 trading arrangements entered into by each of Angelo Amorelli and Gary W. Mize, directors of the Company, during the three months ended December 31, 2024, which were inadvertently omitted from the disclosure included in the Original Filing.
In addition, as required by Rule 12b-15 of the Securities and Exchange Act of 1934, as amended (the "Exchange Act"), new certifications by the Company's principal executive officer and principal financial officer are filed herewith as exhibits to this Amendment, under Item 15 hereof, pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. The Company is also not including new certifications under Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) (Section 906 of the Sarbanes-Oxley Act of 2002), as no financial statements are being filed with this Amendment.
Other than as expressly set forth herein, this Amendment does not, and does not purport to, amend, update or restate the information in the Original Filing or reflect any events that have occurred after the Original Filing was made. Information in the Original Filing not affected by this Amendment remains unchanged and reflects the disclosures made at the time as of which the Original Filing was made. No changes have been made to the financial statements of the Company as contained in the Original Filing. Accordingly, this Amendment should be read together with the Original Filing and the Company's other filings with the SEC. 0001392380 gevo: PaulD.BloomMember gevo: PlanJuly262024ToJuly252025Member 2024-12-31 0001392380 gevo: PaulD.BloomMember gevo: PlanFebruary202025ToFebruary192026Member 2024-12-31 0001392380 gevo: PatrickR.GruberMember gevo: PlanJuly262024ToJuly252025Member 2024-12-31 0001392380 gevo: PatrickR.GruberMember gevo: PlanFebruary172025ToFebruary162026Member 2024-12-31 0001392380 gevo: L.LynnSmullMember gevo: PlanJuly262024ToJuly252025Member 2024-12-31 0001392380 gevo: L.LynnSmullMember gevo: PlanFebruary262025ToFebruary252026Member 2024-12-31 0001392380 gevo: KimberlyT.BowronMember gevo: PlanMarch32025ToMarch42026Member 2024-12-31 0001392380 gevo: KimberlyT.BowronMember gevo: PlanJuly262024ToJuly252025Member 2024-12-31 0001392380 gevo: GaryW.MizeMember gevo: PlanMay232025ToMay222026Member 2024-12-31 0001392380 gevo: ChristopherM.RyanMember gevo: PlanJuly262024ToJuly252025Member 2024-12-31 0001392380 gevo: ChristopherM.RyanMember gevo: PlanFebruary262025ToFebruary252026Member 2024-12-31 0001392380 gevo: AngeloAmorelliMember gevo: PlanMarch72025ToMarch62026Member 2024-12-31 0001392380 gevo: AndrewL.ShaferMember gevo: PlanNovember12024ToOctober312025Member 2024-12-31 0001392380 gevo: AndrewL.ShaferMember gevo: PlanFebruary202025ToFebruary192026Member 2024-12-31 0001392380 gevo: PaulD.BloomMember gevo: PlanJuly262024ToJuly252025Member 2024-10-01 2024-12-31 0001392380 gevo: PatrickR.GruberMember gevo: PlanJuly262024ToJuly252025Member 2024-10-01 2024-12-31 0001392380 gevo: L.LynnSmullMember gevo: PlanJuly262024ToJuly252025Member 2024-10-01 2024-12-31 0001392380 gevo: KimberlyT.BowronMember gevo: PlanJuly262024ToJuly252025Member 2024-10-01 2024-12-31 0001392380 gevo: ChristopherM.RyanMember gevo: PlanJuly262024ToJuly252025Member 2024-10-01 2024-12-31 0001392380 gevo: AndrewL.ShaferMember gevo: PlanNovember12024ToOctober312025Member 2024-10-01 2024-12-31 0001392380 gevo: PaulD.BloomMember gevo: PlanFebruary202025ToFebruary192026Member 2024-10-01 2024-12-31 0001392380 gevo: PatrickR.GruberMember gevo: PlanFebruary172025ToFebruary162026Member 2024-10-01 2024-12-31 0001392380 gevo: L.LynnSmullMember gevo: PlanFebruary262025ToFebruary252026Member 2024-10-01 2024-12-31 0001392380 gevo: KimberlyT.BowronMember gevo: PlanMarch32025ToMarch42026Member 2024-10-01 2024-12-31 0001392380 gevo: GaryW.MizeMember gevo: PlanMay232025ToMay222026Member 2024-10-01 2024-12-31 0001392380 gevo: ChristopherM.RyanMember gevo: PlanFebruary262025ToFebruary252026Member 2024-10-01 2024-12-31 0001392380 gevo: AngeloAmorelliMember gevo: PlanMarch72025ToMarch62026Member 2024-10-01 2024-12-31 0001392380 gevo: AndrewL.ShaferMember gevo: PlanFebruary202025ToFebruary192026Member 2024-10-01 2024-12-31 0001392380 2024-10-01 2024-12-31 0001392380 2024-06-30 0001392380 2025-01-31 0001392380 2024-01-01 2024-12-31 xbrli:shares iso4217:USD

 EXPLANATORY NOTE
 Gevo, Inc. (the "Company") is filing this Amendment No. 1 on Form 10-K/A (this "Amendment") to its Annual Report on Form 10-K for the year ended December 31, 2024, which was originally filed with the Securities and Exchange Commission (the "SEC") on March 27, 2025 (the "Original Filing"). This Amendment is being filed solely to amend Part II "Item 9B. Other Information" by adding Rule 10b5-1 trading arrangements entered into by each of Angelo Amorelli and Gary W. Mize, directors of the Company, during the three months ended December 31, 2024, which were inadvertently omitted from the disclosure included in the Original Filing.
 In addition, as required by Rule 12b-15 of the Securities and Exchange Act of 1934, as amended (the "Exchange Act"), new certifications by the Company's principal executive officer and principal financial officer are filed herewith as exhibits to this Amendment, under Item 15 hereof, pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. The Company is also not including new certifications under Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) (Section 906 of the Sarbanes-Oxley Act of 2002), as no financial statements are being filed with this Amendment.
 Other than as expressly set forth herein, this Amendment does not, and does not purport to, amend, update or restate the information in the Original Filing or reflect any events that have occurred after the Original Filing was made. Information in the Original Filing not affected by this Amendment remains unchanged and reflects the disclosures made at the time as of which the Original Filing was made. No changes have been made to the financial statements of the Company as contained in the Original Filing. Accordingly, this Amendment should be read together with the Original Filing and the Company's other filings with the SEC.

 Item 9B. Other Information
 During the three months ended December 31, 2024, the below directors and/or officers, as defined in Rule 16a-1(f), adopted, modified or terminated a "Rule 10b5-1 trading arrangement," as defined in Item 408 of Regulation S-K.
