Pursuant to the Note Purchase Agreement, Third Eye Capital, as administrative agent on behalf of several noteholders, extended credit in the form of (i) senior secured term loans in an aggregate principal amount of approximately $7.2 million to replace existing notes held by Third Eye Capital (the “Term Notes”); (ii) senior secured revolving loans in an aggregate principal amount of $18.0 million (the “Revolving Credit Facility”); (iii) senior secured term loans in the principal amount of $10.0 million to convert the prior revenue participation agreement to notes (the “Revenue Participation Term Notes”); and (iv) senior secured term loans in an aggregate principal amount of $15.0 million (the “Acquisition Term Notes”) used to fund the cash portion of the acquisition of Cilion, Inc. On May 16, 2023, we entered into a new Revolving Notes Series B agreement with Third Eye Capital related to certain existing principal under the Revolving Credit Facility and for subsequent principal increases. The Term Notes, Revolving Credit Facility, Revolving Notes Series B, Revenue Participation Term Notes, and Acquisition Term Notes are referred to herein collectively as the "Third Eye Capital Keyes Notes." The Third Eye Capital Keyes Notes have been amended several times, and the current key terms are as follows:
A. | Term Notes. The Term Notes accrue interest at 14% per annum and mature on April 1, 2026. As of September 30, 2025, we had $7.3 million in principal, interest and fees outstanding under the Term Notes and $36.2 thousand in unamortized debt issuance costs.
B. | Revolving Credit Facility. The Revolving Credit Facility accrues interest at prime rate plus 13.75% (21.00% as of September 30, 2025) payable monthly in arrears and matures on April 1, 2026. As of September 30, 2025, we had $33.5 million in principal, interest and waiver fees outstanding and $0.2 million in unamortized debt issuance costs under the Revolving Credit Facility.
C. | Revolving Notes Series B. The Revolving Notes Series B accrue interest at prime rate plus 13.75% (21.00% as of September 30, 2025) payable monthly in arrears and mature on April 1, 2026. As of September 30, 2025, we had $81.6 million in principal, interest and waiver fees outstanding and $0.5 million in unamortized debt issuance costs under the Revolving Notes Series B.

The outstanding principal balance includes a $7.5 million redemption fee which is not subject to interest.
The Third Eye Capital Keyes Notes contain various covenants, including but not limited to, debt to plant value ratio, minimum production requirements, and restrictions on capital expenditures. The terms of the Notes allow the lender to accelerate the maturity in the event of a default that could reasonably be expected to have a material adverse effect on the Company, such as any change in the business, operations, or financial condition. We have evaluated the likelihood of such an acceleration event and determined such an event to not be probable in the next twelve months. The notes allow interest to be added to the outstanding principal balance. The notes are secured by first priority liens on all real and personal property of, assignment of proceeds from all government grants, and guarantees from our North American subsidiaries except for Aemetis Biogas LLC and its subsidiaries and contain cross-collateral and cross-default provisions. McAfee Capital, LLC (“McAfee Capital”), owned by Eric McAfee, the Company's Chairman and CEO, provided a guaranty of payment and performance secured by all Company shares owned by McAfee Capital and additional assets, and Mr. McAfee has also provided a personal guaranty of up to $10 million plus a pledge of his ownership interest in several personal assets. Third Eye Capital Credit Facilities for Fuels and Carbon Revolving Lines. On March 2, 2022, Goodland Advanced Fuels, Inc. ("GAFI") and Aemetis Carbon Capture, Inc. (“ACCI”) entered into an Amended and Restated Credit Agreement (“Credit Agreement”) with Third Eye Capital, as administrative agent and collateral agent, and the lender parties thereto that provides two credit lines, one with GAFI (the “Fuels Revolving Line”) and a second with ACCI (the “Carbon Revolving Line”). Loans received under the Fuels Revolving Line had an original maturity date of March 1, 2025, and are now due on demand. They accrue interest per annum at a rate equal to the greater of (i) the prime rate plus 11.00% and (ii) fifteen percent (15.0%). Loans received under the Carbon Revolving Line have a maturity date of March 1, 2026, and accrue interest per annum at a rate equal to the greater of (i) the prime rate plus 4.00% and (ii) eight percent (8.0%). The Credit Agreement contains several affirmative and negative covenants, and loans under the Credit Agreement are secured by first priority liens on all real and personal property of and guarantees from the Company's North American subsidiaries except for Aemetis Biogas LLC. As of September 30, 2025 and December 31, 2024, GAFI had principal and interest outstanding of $47.1 million and $41.7 million, respectively, classified as current debt. As of September 30, 2025 ACCI had principal and interest outstanding of $29.2 million classified as current debt, and $0.4 million in unamortized debt issuance costs.

Cilion Purchase Obligation. In connection with the merger between Aemetis Facility Keyes, Inc. and Cilion, Inc. (“Cilion”) on July 6, 2012, we incurred a $5.0 million payment obligation to Cilion shareholders as merger compensation. The liability accrues interest at 3% per annum. As of September 30, 2025, we had $7.4 million in principal and interest outstanding under the Cilion purchase obligation, classified as current debt. As of December 31, 2024, we had $7.2 million in principal and interest outstanding, classified as long-term debt. Subordinated Notes. Between 2012 and 2013, AAFK entered into Note and Warrant Purchase Agreements with two accredited investors pursuant to which it issued $3.4 million in notes to the investors (“Subordinated Notes”). The Subordinated Notes mature every six months, and the current maturity date is December 31, 2025. Upon maturity, the Subordinated Notes are renewable at our election for six-month periods with a fee of 10% of the original note amount added to the balance outstanding plus issuance of warrants exercisable for the purchase of 113 thousand shares of Aemetis, Inc. common stock at $0.01 per share with a two-year term. Interest accrues at 10% per annum and is due at maturity. Neither AAFK nor Aemetis may make any principal payments under the Subordinated Notes until all AAFK debts to Third Eye Capital are paid in full. As of September 30, 2025, and December 31, 2024, AAFK had, in aggregate, $20.9 million and $19.4 million in principal and interest outstanding, respectively, under the Subordinated Notes. As of September 30, 2025 and December 31, 2024, AAFK had $0.3 million and $0 in unamortized debt issuance costs related to the subordinated notes, respectively. EB-5 Promissory Notes. EB-5 is a U.S. government program authorized by the Immigration and Nationality Act that is designed to foster employment-based visa preference for immigrant investors to encourage the flow of capital into the U.S. economy and to promote employment of U.S. workers. The Company's subsidiary AE Advanced Fuels, Inc. ("AEAF") entered into a Note Purchase Agreement dated March 4, 2011 (as further amended on January 19, 2012 and July 24, 2012) with Advanced BioEnergy, LP, a California limited partnership authorized by U.S. Citizenship and Immigration Services as a Regional Center to receive EB-5 investments, for the issuance of up to 72 subordinated convertible promissory notes (the “EB-5 Notes”) bearing interest at 2 to 3%. The EB-5 Notes are convertible into Aemetis, Inc. common stock at a conversion price of $30 per share. Advanced BioEnergy, LP received equity investments from foreign investors, and then Advanced BioEnergy, LP used the invested equity to make loans to AEAF. The EB-5 Notes are subordinated to the Company's senior secured debt to Third Eye Capital. On February 27, 2019, Advanced BioEnergy, LP, and AEAF entered into an Amendment to the EB-5 Notes that modified the stated maturity dates of the EB-5 Notes to provide automatic six-month extensions as long as the Advanced BioEnergy, LP investors’ immigration processes are in progress. Accordingly, notes derived from Advanced BioEnergy, LP equity provided by investors pending green card approval have been recognized as long-term debt while notes derived from Advanced BioEnergy, LP equity provided by investors who have obtained green card approval have been classified as current debt. As of September 30, 2025, and December 31, 2024, $34.8 million and $34.6 million was outstanding, respectively, on the EB-5 Notes. In 2016, the Company launched its EB-5 Phase II funding (the "EB-5 Phase II Funding") and entered into certain Note Purchase Agreements with Advanced BioEnergy II, LP, a California limited partnership authorized to receive EB-5 equity funding investments. The Company's subsidiary Aemetis Advanced Products Keyes, Inc. received $4 million in loan funds from Advanced BioEnergy II, LP from 2018 to 2019. As of both September 30, 2025, and December 31, 2024, $4.5 million was outstanding on the notes under the EB-5 Phase II funding, respectively. In July 2024, in connection with settlement of litigation initiated by a broker previously engaged by Advanced BioEnergy, LP, we entered into an agreement to pay the broker certain of its claimed fees. In April 2025, that broker initiated litigation against Aemetis, Inc. to collect $2.3 million (plus interest and fees) under the agreement. The liability previously accrued for the amount at issue in the litigation has been reclassified from debt as of December 31, 2024, to other current liabilities as of September 30, 2025. India Biodiesel Secured and Unsecured Loans. On November 13, 2023, the Company's subsidiary Universal Biofuels Private Limited ("UBPL") entered into a secured loan agreement with a trade partner in an amount not to exceed $3.6 million that is secured by the fixed and currents assets of the Kakinada Plant. On November 6, 2023, UBPL entered into a short-term loan agreement with a different trade partner in an amount not to exceed $1.27 million. Each loan bears interest at 18% that is payable monthly. The loans are repayable on demand by the lenders, or by the extended maturity date in November 2025. As of September 30, 2025, and December 31, 2024, UBPL had outstanding balances under these agreements totaling $0.0 million and $5.1 million, respectively. The India biodiesel segment maintains a factoring arrangement under which we leverage certain trade receivables to receive short-term funding from a third-party financial institution. We retain the risk of nonpayment on the transferred receivables, so the arrangement does not meet the criteria for sale accounting under ASC 860, and we account for the funding as secured borrowing. Under this arrangement, the company receives cash advances which are recorded as debt, and the funds received are net of 8.1% interest which is recorded as interest expense. We retain our accounts receivable balances in the balance sheet. During the nine months ended September 30, 2025, we received a total of $23 million in draws in this agreement, net of 8.1% interest. As of both September 30, 2025 and December 31, 2024, we had no outstanding debt under this agreement. Aemetis Biogas 1 LLC Term Loan. On October 4, 2022, Aemetis Biogas 1 LLC ("AB1") entered into a Construction Loan Agreement ("AB1 Construction Loan") pursuant to which the lender made available an aggregate principal amount of $25 million. Effective December 22, 2023, the AB1 Construction Loan was refinanced and replaced with a term loan ("AB1 Term Loan") that is secured by all personal and real property of AB1. It bears interest at a rate of 9.25% per annum, to be adjusted every five years to equal the five-year Treasury Constant Maturity Rate, as published by the Board of Governors of the Federal Reserve System as of the adjustment date, plus 5.00% or (ii) the index floor. Other material terms of the loan include: (i) monthly payments of interest only beginning January 22, 2024, (ii) equal monthly payments of principal and interest beginning January 22, 2025, and (iii) a maturity date of December 22, 2042, at which time the entire unpaid principal amount, together with accrued and unpaid interest, is due and payable.
