Accounting Policies [Abstract] |
Organization and Business | Organization and Business – The consolidated financial statements include, for all periods presented, the accounts of Alto Ingredients, Inc., a Delaware corporation (“Alto Ingredients”), and its direct and indirect wholly-owned subsidiaries (collectively, the “Company”), including Kinergy Marketing LLC, an Oregon limited liability company (“Kinergy”), Alto Nutrients, LLC, a California limited liability company (“Alto Nutrients”), Alto Op Co., a Delaware corporation, Alto Pekin, LLC, a Delaware limited liability company (“Alto Pekin”) and Alto ICP, LLC, a Delaware limited liability company (“ICP”), and the Company’s production facilities in Oregon and Idaho. As discussed in Note 2, on January 1, 2025, the Company’s wholly-owned subsidiary, Alto Carbonic, LLC (“Alto Carbonic”), acquired Kodiak Carbonic, LLC, a beverage-grade liquid CO2 processor, for $7.6 million. Alto Carbonic’s facility is co-located at the Company’s Columbia ethanol plant in Boardman, Oregon. The Company began reporting the results of Alto Carbonic in the Company’s Western Production segment on January 1, 2025. The Company produces and distributes renewable fuels, essential ingredients and specialty alcohols. The Company also markets fuel-grade ethanol produced by third parties. The Company’s production facilities in Pekin, Illinois are located in the heart of the Corn Belt. The Company’s two production facilities in Boardman, Oregon and Burley, Idaho are located in close proximity to both feed and fuel-grade ethanol customers. The Company has a combined alcohol production capacity of 350 million gallons per year and produces, on an annualized basis, over 1.4 million tons of essential ingredients, such as dried yeast, corn protein meal, corn protein feed, corn germ, and distillers grains and liquid feed used in commercial animal feed and pet foods. In addition, the Company markets and distributes fuel-grade ethanol produced by third parties. The Company focuses on Health, Home & Beauty; Food & Beverage; Industry & Agriculture; Essential Ingredients; and Renewable Fuels markets. Products for the Health, Home & Beauty market include specialty alcohols used in mouthwash, cosmetics, pharmaceuticals, hand sanitizers, disinfectants and cleaners. Products for the Food & Beverage markets include grain neutral spirits used in alcoholic beverages and vinegar as well as corn germ used for corn oils. Products for Industry & Agriculture markets include alcohols and other products for paint applications and fertilizers. Products for Essential Ingredients markets include dried yeast, corn protein meal, corn protein feed, corn germ, and distillers grains and liquid feed used in commercial animal feed and pet foods. Products for Renewable Fuels markets include fuel-grade ethanol and distillers corn oil used as a feedstock for renewable diesel and biodiesel fuels. The Company’s production facilities, other than its Magic Valley plant located in Burley, Idaho, were operating for all periods presented subject to scheduled and unscheduled downtimes to address facility repair and maintenance. In January 2024, the Company temporarily hot-idled its Magic Valley facility to minimize losses from negative regional crush margins and to expedite the installation of additional equipment to achieve the intended production rate, quality and consistency from the Company’s corn oil and high protein system at the facility. The Company restarted its Magic Valley facility in July 2024 and by October 2024, the facility consistently achieved average ethanol production rates at full capacity, the protein content yield from the plant reached 50% or greater, and the Company was able to expand its corn oil yields. Increases in regional corn basis and declining market prices for protein and corn oil resulted in overall margin compression, outweighing the economic benefits of these plant improvements. As a consequence, the Company cold-idled its Magic Valley facility on December 31, 2024 to minimize financial losses. The Company continues to provide terminal services at the plant.
Basis of Presentation–Interim Financial Statements | Basis of Presentation–Interim Financial Statements – The accompanying unaudited consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Results for interim periods should not be considered indicative of results for a full year. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. The accounting policies used in preparing these consolidated financial statements are the same as those described in Note 1 to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement of the results for interim periods have been included. All significant intercompany accounts and transactions have been eliminated in consolidation.
Accounts Receivable and Allowance for Credit Losses | Accounts Receivable and Allowance for Credit Losses – Trade accounts receivable is presented at original invoice amount, net of the allowance for credit losses. The Company sells specialty alcohols to large consumer product companies, sells fuel-grade ethanol to gasoline refining and distribution companies, sells essential ingredients such as dried yeast for human and pet food and to animal feed customers, including distillers grains to export markets, sells those same and other feed co-products to dairy operators and animal feedlots and sells corn oil to poultry, renewable diesel and biodiesel customers, in each case generally without requiring collateral. The carrying amount of accounts receivable is reduced by a valuation allowance that reflects the Company’s best estimate of the amounts that will not be collected. The Company regularly reviews accounts receivable and based on assessments of current customer creditworthiness, estimates the portion, if any, of the customer balance that will not be collected. Of the accounts receivable balance, approximately $46,146,000 and $44,750,000 at September 30, 2025 and December 31, 2024, respectively, were used as collateral under Kinergy’s operating line of credit. The allowance for credit losses was $19,000 and $23,000 as of September 30, 2025 and December 31, 2024, respectively. The Company recorded a credit loss recovery of $3,000 and $24,000 for the three months ended September 30, 2025 and 2024, respectively. The Company recorded a credit loss recovery of $4,000 and $23,000 for the nine months ended September 30, 2025 and 2024, respectively. The Company does not have any off-balance sheet credit exposure related to its customers.
Financial Instruments | Financial Instruments – The carrying values of cash and cash equivalents, restricted cash, accounts receivable, derivative assets, accounts payable, accrued liabilities and derivative liabilities are reasonable estimates of their fair values because of the short maturity of these items. The Company believes the carrying value of its long-term debt instruments are not considered materially different than fair value.
Estimates and Assumptions | Estimates and Assumptions – The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates are required as part of determining the allowance for credit losses, net realizable value of inventory, long-lived asset impairments, valuation allowances on deferred income taxes, the potential outcome of future tax consequences of events recognized in the Company’s financial statements or tax returns, and the valuation of assets acquired and liabilities assumed as a result of business combinations. Actual results and outcomes may materially differ from management’s estimates and assumptions.
