Substantial Doubt about Going Concern [Text Block]

16. Liquidity

The accompanying financial statements have been prepared contemplating the realization of assets and satisfaction of liabilities in the normal course of business. As a result of negative capital, negative operating results, and collateralization of substantially all of the Company assets, the Company has been reliant on its senior secured lender to provide extensions to the maturity dates of its debt and loan facilities, and was required in 2023 to remit excess cash from operations to the senior secured lender. In order to meet our obligations during the next twelve months, we will need to refinance debt with our senior lender for amounts becoming due in the next twelve months or receive the continued cooperation of our senior lender. This dependence on our senior lender raises substantial doubt about the Company's ability to continue as a going concern. While we believe our India biodiesel and California RNG businesses will generate positive cash flow from operations in 2024 which reduces cash demands and allows payments against other obligations, we will also continue to sell equity through our at-the-market registration at consistent levels and pursue the following strategies to improve liquidity:

Operations and Project Development

For the Keyes Plant, we plan to operate the plant and continue to improve its financial performance by adopting new technologies or process changes that allow for energy efficiency, cost reduction, or revenue enhancements, as well as, execute upon awarded grants that support investments in equipment to improve energy and operational efficiencies resulting in lower cost, lower carbon emissions, and overall margin improvement.

For Aemetis Biogas, we plan to operate our existing biogas digesters to produce and sell Renewable Natural Gas (RNG) and the associated Federal D3 RINs and California LCFS credits. We are continuing to build new dairy digesters and pipeline extensions. We began generating revenue from biogas operations in 2023 and we expect that this revenue will continue for the full year 2024, as well as increase as we build new digesters. We also expect revenue to increase when the California Air Resource Board processes our LCFS pathway applications and approves a provisional carbon intensity that is lower than the temporary carbon intensity we currently use to calculate the quantity of LCFS credits that we generate.

We are also continuing to upgrade the plant to increase feedstock flexibility (and thereby lower feedstock costs), increase production capacity, and produce new products. Additionally, we are in the process of negotiating contractual arrangements for the export of refined animal tallow into international markets.

Financing

We plan to continue to locate funding for existing and new business opportunities through a combination of working with our senior lender, restructuring existing loan agreements, entering into additional debt agreements for specific projects, obtaining project specific equity and debt for development projects, and obtaining additional debt from the current EB-5 Phase II offering.
