Risk factors and legal proceedings

The risks Alto Ingredients, Inc. names in Item 1A of its 10-K filed Mar 13, 2026: 24 risks under these headings, as written.⁴

• Our results of operations and our ability to operate at a profit are largely dependent on our ability to manage the costs of corn, natural gas and other production inputs, with the prices of our alcohols and essential ingredients, all of which are subject to volatility and uncertainty.
• The prices of our products are volatile and subject to large fluctuations, which may cause our results of operations to fluctuate significantly.
• We may engage in hedging transactions and other risk mitigation strategies that could harm our results of operations and financial condition.
• Disruptions in our production or distribution, including from climate change and other weather effects, may adversely affect our business, results of operations and financial condition.
• Increased alcohol or essential ingredient production or higher inventory levels may cause a decline in prices for those products, and may have other negative effects, materially and adversely impacting our results of operations, cash flows and financial condition.
• We may suffer impairments in the value of our long-lived assets which may materially and adversely affect our results of operations.
• Our alcohol production relies on traditional corn-based feedstock and process technologies. New technologies could make corn-based alcohol production and traditional process technologies less competitive or even obsolete, materially and adversely harming our business.
• Inflation and sustained higher prices may adversely impact our results of operations and financial condition.
• Climate change, and governmental regulations aimed at addressing climate-related issues, may affect conditions to which our business is highly sensitive, many of which could materially and adversely harm our business, results of operations and financial condition.
• Risks Related to our Finances
• We have incurred significant losses and negative operating cash flow in the past and we may incur losses and negative operating cash flow in the future, which may hamper our operations and impede us from expanding our business.
• We are engaged in multiple capital improvement initiatives and projects. These initiatives and projects, and their financing, costs, timing and effects, are based on our plans, expectations and various assumptions that may not eventuate. We may therefore be unable to timely achieve, or achieve at all, the results we expect.

Legal proceedings

We are subject to legal proceedings, claims and litigation arising in the ordinary course of business. While the amounts claimed may be substantial, the ultimate liability cannot presently be determined because of considerable uncertainties that exist. Therefore, it is possible that the outcome of those legal proceedings, claims and litigation could adversely affect our quarterly or annual operating results or cash flows when resolved in a future period. However, based on facts currently available, management believes such matters will not adversely affect in any material respect our financial position, results of operations or cash flows.
