Basis of Presentation and Significant Accounting Policies [Text Block]	1. General Nature of Activities Founded in 2006 and headquartered in Cupertino, California, Aemetis, Inc. (collectively with its subsidiaries on a consolidated basis referred to herein as “Aemetis,” the “Company,” “we,” “our” or “us”) is an international renewable natural gas and renewable fuels company focused on the operation, acquisition, development, and commercialization of innovative technologies to produce low and negative carbon intensity renewable fuels that lower fuel costs and reduce emissions. We do this by building a local circular bioeconomy using agricultural products and waste materials to produce low carbon, advanced renewable fuels that reduce greenhouse gas ("GHG") emissions and improve air quality. ► California Ethanol – We own and operate a 65 million gallon per year capacity ethanol production facility in Keyes, California (the “Keyes Plant”). In addition to low carbon renewable fuel ethanol, the Keyes Plant produces Wet Distillers Grains (“WDG”), Distillers Corn Oil (“DCO”), and Condensed Distillers Solubles (“CDS”). WDG and CDS are sold to local dairies or feedlots as animal feed, and DCO is sold to commodity aggregators as feedstock for the production of Renewable Diesel. The Keyes Plant also sells Carbon Dioxide (“CO₂") captured from the fermentation process to produce commercial grade CO₂ for the food, beverage, and other industries. We are implementing several energy efficiency initiatives at the Keyes Plant focused on reducing operating costs and lowering the carbon intensity of our ethanol to increase revenues. ► California Dairy Renewable Natural Gas – We produce Renewable Natural Gas ("RNG") in central California. We currently have twelve anaerobic digesters that produce biogas from dairy waste received from fifteen dairies, a 36-mile biogas collection pipeline leading to a central RNG production facility, and an interconnection to inject the RNG into the utility natural gas pipeline for delivery for use as transportation fuel. We are actively expanding our RNG production, with two additional dairy digesters under construction, agreements with over fifty dairies, and environmental review completed for an additional 24 miles of biogas pipeline. We are also building our own RNG fuel dispensing station, which is planned to begin operating in 2026. ► India Biodiesel – We own and operate a plant in Kakinada, India (“Kakinada Plant”) with a capacity to produce about 80 million gallons per year of high-quality distilled biodiesel from a variety of vegetable oils and animal waste feedstocks. The Kakinada Plant is one of the largest biodiesel production facilities in India. The Kakinada Plant refines and converts the crude glycerin, a byproduct from biodiesel production, into refined glycerin, which meets the quality standards for selling into the pharmaceutical, personal care, paint, adhesive, and other sectors, supporting their manufacturing and production needs. Our current and planned businesses produce renewable fuels and reduce emissions, generating revenues from biofuel sales, federal Renewable Fuel Standard ("RFS") credits (referred to as “D3 RINs”), federal Section 45Z production tax credits (“Section 45Z PTCs” or “PTCs”), California Low Carbon Fuel Standard (“LCFS”) credits, and other investment and production tax credits. Basis of Presentation and Consolidation These consolidated condensed financial statements include the accounts of Aemetis, Inc. and its subsidiaries. We consolidate all entities in which we hold a "controlling financial interest." For voting interest entities, we are considered to hold a controlling financial interest when we are able to exercise control over the investees' operating and financial decisions. For variable interest entities ("VIEs"), the determination of which is based on the amount and characteristics of the entity's equity, we are considered to hold a controlling financial interest when we are determined to be the primary beneficiary. A primary beneficiary is the party that has both: (1) the power to direct the activities that most significantly impact that VIE's economic performance, and (2) the obligation to absorb the losses of, or the right to receive the benefits from, the VIE that could potentially be significant to that VIE.

The financial statements in this report should be read in conjunction with the 2025 audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025. There have been no material changes to our significant accounting policies disclosed in Note 1 - Nature of Activities and Summary of Significant Accounting Policies and other Notes to the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The accompanying consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of the Company’s management, the unaudited interim consolidated condensed financial statements as of and for the three and six months ended June 30, 2026 and 2025, have been prepared on the same basis as the audited consolidated statements as of and for the year ended December 31, 2025, and reflect all adjustments, consisting primarily of normal recurring adjustments, necessary for the fair presentation of its statement of financial position, results of operations and cash flows. The results of operations for the three and six months ended June 30, 2026, are not necessarily indicative of the operating results for any subsequent quarter, for the full fiscal year, or any future periods. In the fourth quarter of 2025 we adopted a policy to account for transferable PTCs by analogy to the grant model within International Accounting Standards 20 (IAS20), to recognize the credits when earned upon production and dispensing of eligible RNG and ethanol. We presented all twelve months of 2025 PTC earnings in the fourth quarter of 2025 as income separate from revenue in the consolidated statement of operations and comprehensive loss. Starting in the first quarter of 2026, PTCs are presented within Revenues. Starting in the second quarter of 2026, accrued but unmonetized Section 45Z PTCs are presented as a separate line item on the consolidated condensed balance sheets. The prior period amount of $5.5 million as of December 31, 2025, which was previously included within other current assets, has been reclassified to conform to the current period presentation. This change in presentation had no effect on total current assets, total assets, net income, or cash flows. Recent Accounting Pronouncements In May 2026, the Financial Accounting Standards Board ("FASB") issued ASU 2026-02, Environmental Credits and Environmental Credit Obligations (Topic 818), which establishes accounting and disclosure requirements for environmental credits and environmental credit obligations that will begin to apply in 2028. The Company's operations involve environmental credits, including Renewable Identification Numbers ("RINs"), Low Carbon Fuel Standard ("LCFS") credits, and other types of credits. The Company is currently evaluating the impact of the new guidance on its accounting policies, financial statement presentation, and disclosures. The Company has not yet determined the impact that adoption of this standard will have on its consolidated financial statements and related disclosures.
