PART I

Item 1. Business.

Business Overview

We are a leading producer and distributor of specialty alcohols, renewable fuels and essential ingredients in the United States.

We operate five alcohol production facilities. Three of our production facilities are located in Illinois, one is located in Oregon and another is located in Idaho. We have an annual alcohol production capacity of 350 million gallons, including both renewable fuels and specialty alcohols ranging from industrial-, pharmaceutical-, and high-quality food- and beverage-grade alcohols. Of this amount, we can produce up to 110 million gallons annually of specialty alcohols, depending on our product mix among high-quality beverage-grade alcohol and other quality specification alcohols. We market and distribute all of the alcohols produced at our facilities as well as alcohols produced by third parties. In 2024, we marketed and distributed approximately 386 million gallons combined of our own produced alcohols as well as fuel-grade ethanol produced by third parties, and over 1.4 million tons of essential ingredients on a dry matter basis.

We also own and operate a liquid carbon dioxide, or CO₂, production facility adjacent to our plant in Oregon for the offtake of CO₂ gas from the plant for conversion to liquid CO₂ and subsequent sale. We acquired this facility on January 1, 2025.

In addition, we break bulk and distribute specialty alcohols, produced by us and third parties, through our Eagle Alcohol business.

We report our financial and operating performance in three distinct segments:

Our mission is to produce the highest quality, sustainable ingredients that make everyday products better. We intend to accomplish this goal in part by investing in our specialized and higher value specialty alcohol production and distribution infrastructure, expanding production in high-demand essential ingredients, expanding and extending the sale of our products into new regional and international markets, building efficiencies and economies of scale and by capturing a greater portion of the value stream.

Production Segments

We produce specialty alcohols, renewable fuels and essential ingredients, focusing on five key markets: Health, Home & Beauty; Food & Beverage; Industry & Agriculture; Essential Ingredients; and Renewable Fuels. Products for Health, Home & Beauty markets include specialty alcohols used in mouthwash, cosmetics, pharmaceuticals, hand sanitizers, disinfectants and cleaners. Products for Food & Beverage markets include grain neutral spirits used in alcoholic beverages and vinegar and corn germ used for corn oils. Products for Industry & Agriculture markets include alcohols and other products for paint applications, vehicle fluids and fertilizers. Products for Essential Ingredients markets include dried yeast, corn protein meal, corn protein feed, corn germ, distillers grains, liquid CO₂ and liquid feed used in commercial animal feed and pet foods. We also sell yeast and liquid CO₂ for human consumption. Our products for the Renewable Fuels markets include fuel-grade ethanol and distillers corn oil used as a feedstock for renewable diesel and biodiesel fuels. Our specialty alcohols for the Industry & Agriculture, Food & Beverage and Health, Home & Beauty markets represented approximately 12%, 7% and 3%, respectively, of our sales in 2024 from these three markets.

We produce our alcohols and essential ingredients at our facilities described below. Our production facilities located in Illinois are in the heart of the Corn Belt, benefit from relatively low-cost and abundant feedstock and enjoy logistical advantages that enable us to provide our products to both domestic and international markets via truck, rail or barge. Our production facilities located in Oregon and Idaho are near their respective fuel and feed customers, offering significant timing, product transportation cost and logistical advantages.

All of our production facilities, other than our Magic Valley plant, were operating for all of 2024, subject to scheduled and unscheduled downtimes to address facility repair and maintenance.

In January 2024, we temporarily hot-idled our 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 our corn oil and high protein system at the facility. We restarted our 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 we were able to expand our 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 our plant improvements. As a consequence, we cold-idled our Magic Valley facility on December 31, 2024 to minimize financial losses. We continue to provide terminal services at the plant and intend to resume operations at the facility when the economic environment in the region sustainably improves. We believe that the cold-idling of our Magic Valley facility will have a positive impact on our overall financial results in 2025 compared to 2024.

As market conditions change, we may increase, decrease or idle production at one or more operating facilities or resume operations at any idled facility.

Marketing and Distribution Segment

We market and distribute all the alcohols and essential ingredients we produce at our facilities. We also market and distribute alcohols produced by third parties.

We have extensive and long-standing customer relationships, both domestic and international, for our specialty alcohols and essential ingredients. These customers include producers and distributors of ingredients for cosmetics, sanitizers and related products, distilled spirits producers, food products manufacturers, producers of personal health/consumer health and personal care hygiene products, and global trading firms.

Our renewable fuel customers are located throughout the Western and Midwestern United States and consist of integrated oil companies and gasoline marketers who blend fuel-grade ethanol into gasoline. Our customers depend on us to provide a reliable supply of fuel-grade ethanol and manage the logistics and timing of delivery. Our customers collectively require fuel-grade ethanol volumes in excess of the supplies we produce at our facilities. We secure additional fuel-grade ethanol supplies from third-party ethanol producers. We arrange for transportation, storage and delivery of fuel-grade ethanol purchased by our customers through our agreements with third-party service providers in the Western United States as well as in the Midwest from a variety of sources.

We market food-grade essential ingredients to human and pet food markets, our feed products (such as distillers grains) primarily to export markets from our Pekin Campus, and other feed products to dairies and feedlots, in many cases located near our production facilities. These customers use our feed products for livestock as a substitute for corn and other sources of starch and protein. We sell our corn oil to poultry, renewable diesel and biodiesel customers.

Business Strategy

The key elements of our business and growth strategy include:

Competitive Strengths

We believe that our competitive strengths include:

Overview of Our Key Markets and Market Opportunity

We produce specialty alcohols, renewable fuels and essential ingredients, focusing on five key markets: Health, Home & Beauty; Food & Beverage; Industry & Agriculture; Essential Ingredients; and Renewable Fuels.

Health, Home & Beauty

Our products for the health, home and beauty markets include specialty alcohols used in mouthwash, cosmetics, pharmaceuticals, hand sanitizers, disinfectants and cleaners. We offer a variety of specialty alcohols for the health, home and beauty markets, depending on usage and regulatory requirements, including API-grade or USP-grade ethyl alcohols, and industrial-grade ethyl alcohol.

We have ISO 9001, FSSC 22000, ICH Q7 and EXCiPACT certifications, all of which are viewed as important attestations of quality control standards. In particular, our ICH Q7 certification qualifies our specialty alcohols for use as an API, and our EXCiPACT certification qualifies our specialty alcohols for use as an excipient in the pharmaceutical industry. These certifications enable us to offer products to a wider group of customers and generally at more profitable margins.

Food & Beverage

Our products for the food and beverage market include specialty alcohols used in alcoholic beverages, flavor extracts and vinegar as well as corn germ used for corn oils and CO₂ used for beverage carbonation and dry ice. We offer grain neutral spirits, or GNS, alcohol as our primary specialty alcohol for beverage-grade products. In addition, we sell FCC 190 and USP 190 Ultra into vinegar markets. We also sell high-quality 192 proof and low-moisture 200-proof GNS products to customers in the beverage, food, flavor and personal care industries.

We believe the key drivers in the food and beverage market include consumer preferences for the social currency of brand authenticity and heritage; consumers seeking unique and personalized experiences; improved consumer access to spirits products; the growth of craft distillers; and the ability to meet wide-ranging consumer preferences through a broad diversity of spirits categories and cocktails.

Industry & Agriculture

Our products for the industry and agriculture market include alcohols and other products for paint applications, vehicle fluids and fertilizers.

Essential Ingredients

Our essential ingredients include dried yeast, corn protein meal, corn protein feed, and distillers grains and liquid feed used in commercial animal feed and pet foods. In addition, we sell yeast for human consumption. We also produce and sell liquid CO₂. The raw materials for our essential ingredients are generated as co-products from our production of alcohols. These co-products are further manufactured, altered and refined into our essential ingredients, including for special customer applications.

Many of our essential ingredients are used in a variety of food products to affect their nutrition, including protein and fat content, as well as other product attributes such as taste, texture, palatability and stability. Our high quality and high purity manufacturing enables our customers to use some of our essential ingredients in human foods while others are used solely in pet foods and animal feed.

We expect the essential ingredients market to grow significantly due to global demand for higher-grade protein feed, such as feed used in fisheries and other applications for plant-based proteins.

Renewable Fuels

Our renewable fuels products include fuel-grade ethanol primarily used as a transportation fuel additive and distillers corn oil used as a renewable diesel and biodiesel feedstock. Our renewable fuels business is supported by our own production of fuel-grade ethanol as well as fuel-grade ethanol produced by third parties.

Renewable fuels, primarily fuel-grade ethanol, are used for a variety of purposes, including as octane enhancers for premium gasoline and to enable refiners to produce greater quantities of lower octane blend stock; for fuel blending to extend fuel supplies and reduce reliance on crude oil and refined products; and to comply with a variety of governmental programs, in particular, the national Renewable Fuel Standard, or RFS, enacted to promote alternatives to fossil fuels. Under the RFS, the mandated use of all renewable fuels rose incrementally and peaked at 36.0 billion gallons in 2022, of which production of 15.0 billion gallons was required from conventional, or corn-based, ethanol. The RFS allows the Environmental Protection Agency, or EPA, to adjust the annual requirement based on certain facts and circumstances. The EPA set its annual requirement for conventional ethanol to 15.0 billion gallons for 2025. See “—Governmental Regulation.”

According to the Renewable Fuels Association, the domestic fuel-grade ethanol industry produced over 16.1 billion gallons of ethanol in 2024, up from 15.5 billion gallons of ethanol in 2023. According to the United States Department of Energy, total annual gasoline consumption in the United States is approximately 137 billion gallons and total annual fuel-grade ethanol blended with gasoline represented approximately 10.4% of this amount in 2024. We anticipate that continued limited opportunities for gasoline refinery expansions and the growing importance of reducing CO₂ emissions using renewable fuels will generate additional growth in the demand for fuel-grade ethanol.

Overview of Alcohol Production Process

Alcohol production from starch- or sugar-based feedstock is a highly efficient process. Modern alcohol production requires large amounts of corn, or other high-starch grains, and water as well as chemicals, enzymes and yeast, in addition to natural gas and electricity.

Dry Milling Process

In the dry milling process, corn or other high-starch grain is first ground into flour, then slurried with water to form a mash. Enzymes are added to the mash to convert the starch into dextrose, a simple sugar. The mash is processed through a high temperature cooking procedure, which reduces bacteria levels prior to fermentation. The mash is then cooled and transferred to fermenters, where yeast is added and the conversion of sugar to alcohol and CO₂ begins.

After fermentation, the resulting “beer” is transferred to distillation where the alcohol is separated from the residual “stillage.” The resulting alcohol is concentrated to 190 proof using conventional distillation methods. It can then be dehydrated to approximately 200 proof, representing 100% alcohol levels, in either a molecular sieve system or a grits system. For fuel-grade ethanol, the resulting anhydrous alcohol is then blended with up to 2.5% denaturant, usually gasoline, and then shipped to renewable fuels markets. For specialty alcohols, the products can be sold pure or as one of the Alcohol Tobacco Tax & Trade Bureau (TTB) approved specially denatured alcohol (SDA) formulations to meet customer specifications.

The residual stillage is separated into a coarse grain portion and a liquid portion through a screw press or centrifugation process. The soluble liquid portion is concentrated to about 40% dissolved solids by an evaporation process. This intermediate state is called condensed distillers solubles, or syrup. The coarse grain and syrup portions are then mixed to produce wet distillers grains with solubles, or WDGS, or can be mixed and dried to produce dried distillers grains with solubles, or DDGS. Both WDGS and DDGS are high-protein animal feed products.

Wet Milling Process

In the wet milling process, corn or other high-starch grain is first soaked or “steeped” in sulfurous acid for approximately 24 hours to soften the whole corn kernel prior to milling. After steeping, the grain is coarse milled to gently open the kernels to separate the corn germ and from which corn oil is further extracted in a separate process. The remaining fiber, protein and starch components are further separated and sold.

The stillage from the fermentation process is concentrated in an evaporator and is co-dried with the fiber component and sold as corn protein feed. The protein component is separated from the starch, filtered and dried to produce corn protein meal, a product with greater than 60% protein content. The starch component is processed into alcohol through fermentation. The fermentation process for alcohol at this stage is similar to the dry milling process. In addition, we separate and dry yeast to produce distillers yeast.

Overview of Distillers Grains Market

Distillers grains are produced as a co-product of alcohol production and are valuable components of feed rations primarily to dairies and beef cattle markets, both nationally and internationally. Our plants produce both WDGS and DDGS. WDGS is sold to customers proximate to the plants and DDGS is delivered by truck, rail and barge to customers in domestic and international markets. Producing WDGS uses up to one-third less process energy, thus reducing production costs and lowering the carbon footprint of our Western production facilities.

Historically, the market price for distillers grains has generally tracked the price of corn. We believe that the market price of WDGS and DDGS is determined by a number of factors, including the market prices of corn, soybean meal and other competitive ingredients, the performance or value of WDGS and DDGS in a particular feed formulation and general market forces of supply and demand, including export markets for these essential ingredients. The market price of distillers grains is also often influenced by nutritional models that calculate the feed value of distillers grains by nutritional content, as well as reliability of consistent supply.

Customers

Our Kinergy Marketing LLC, or Kinergy, subsidiary sells all of our produced alcohols and also markets fuel-grade ethanol produced by third parties. Our Alto Nutrients, LLC subsidiary sells all of the essential ingredients we produce. Our Alto Carbonic, LLC subsidiary sells all of the liquid CO₂ we produce and our Eagle Alcohol business sells our alcohols and third-party alcohols in break bulk quantities to customers in the beverage, food, industrial and related-process industries.

We have extensive and long-standing customer relationships, both domestic and international, for our specialty alcohols and essential ingredients, including yeast for pet food and human foods. These customers include producers and distributors of ingredients for cosmetics, sanitizers and related products, distilled spirits producers, food products manufacturers, producers of personal health/consumer health and personal care hygiene products, and global trading firms.

Our renewable fuel customers are located throughout the Western and Midwestern United States and consist of integrated oil companies and gasoline marketers who blend fuel-grade ethanol into gasoline. Our customers depend on us to provide a reliable supply of fuel-grade ethanol and manage the logistics and timing of delivery. We secure additional fuel-grade ethanol supplies from third-party fuel-grade ethanol plants.

We market our essential ingredient feed products to dairies and feedlots, in many cases located near our production facilities. These customers use our feed products for livestock as a substitute for corn and other sources of starch and protein. We sell our corn oil to poultry, renewable diesel and biodiesel customers.

For 2024, 2023 and 2022, sales to our two largest customers, Chevron Products USA and Shell Trading (US) Company represented an aggregate of approximately 18%, 16% and 20% of our net sales, respectively. For 2024, 2023 and 2022, sales to each of our other customers represented less than 10% of our net sales.

Suppliers

Pekin Campus and Western Production Segments

Our production operations depend upon various raw materials suppliers, including suppliers of corn, natural gas, electricity and water. The cost of corn, including delivery costs, is the most important variable cost associated with our alcohol production. We source corn for our plants using standard contracts, including spot purchase, forward purchase and basis contracts. When resources are available, we seek to limit the exposure of our production operations to raw material price fluctuations by purchasing forward a portion of our corn requirements on a fixed price basis and by purchasing corn and other raw materials futures contracts and options.

During 2024, 2023 and 2022, purchases of corn from our three largest suppliers represented an aggregate of approximately 29%, 26% and 38% of our total corn purchases, respectively, for those periods. Purchases from each of our other corn suppliers represented less than 10% of total corn purchases in each of 2024, 2023 and 2022.

Marketing and Distribution Segment

Our marketing and distribution operations include alcohols and essential ingredients we produce but also depend upon various third-party producers of fuel-grade ethanol. In addition, we provide transportation, storage and delivery services through third-party service providers with whom we have contracted to receive fuel-grade ethanol at agreed upon locations from our third-party suppliers and to store and/or deliver the ethanol to agreed-upon locations on behalf of our customers. These contracts generally run from year-to-year, subject to termination by either party upon advance written notice before the end of the then-current annual term.

During 2024, 2023 and 2022, we purchased and resold from third parties an aggregate of approximately 108 million, 103 million and 118 million gallons, respectively, of fuel-grade ethanol.

During 2024, 2023 and 2022, purchases of fuel-grade ethanol from our four largest third-party suppliers represented 79%, 86% and 69%, respectively, of our total third-party ethanol purchases for each of those periods. Purchases from each of our other third-party ethanol suppliers represented less than 10% of total third-party ethanol purchases in each of 2024, 2023 and 2022.

Production Facilities

We operate five alcohol production facilities. Three of our production facilities are located in Illinois, one is located in Oregon and another is located in Idaho. We have an annual alcohol production capacity of up to 350 million gallons, including both fuel-grade ethanol and specialty alcohols ranging from industrial-, pharmaceutical-, and high-quality food- and beverage-grade alcohols. Of this amount, we are able to produce up to 110 million gallons annually of specialty alcohols, depending on our product mix among high-quality beverage-grade alcohol and other quality specification alcohols. We also own and operate a liquid CO₂ production facility adjacent to our plant in Oregon for the offtake of CO₂ gas from the plant for conversion to liquid CO₂ and subsequent sale.

The tables below provide an overview of our five alcohol production facilities and our liquid CO₂ production facility. As market conditions change, we may increase, decrease or idle production at one or more operating facilities or resume operations at any idled facility.

Pekin Campus Production Facilities

Western Production Facilities

Commodity Risk Management

We employ various risk mitigation techniques. For example, we may seek to mitigate our exposure to commodity price fluctuations by purchasing forward a portion of our corn and natural gas requirements through fixed-price or variable-price contracts with our suppliers, as well as entering derivative contracts for fuel-grade ethanol, corn and natural gas. To mitigate fuel-grade ethanol inventory price risks, we may sell a portion of our production forward under fixed- or index-price contracts, or both. We may hedge a portion of the price risks by entering exchange-traded futures contracts and options. Properly executing these risk mitigation strategies can reduce the volatility of our gross profit margins.

Specialty alcohols have relatively low price volatility and are usually priced at significant premiums to fuel-grade ethanol. The market price of fuel-grade ethanol is volatile, however, and subject to large fluctuations. Given the nature of our business, we cannot effectively hedge against extreme volatility or certain market conditions. For example, fuel-grade ethanol prices, as reported by the Chicago Mercantile Exchange, or CME, ranged from $1.38 to $2.12 per gallon during 2024, from $1.58 to $2.67 per gallon during 2023 and from $2.00 to $2.88 per gallon during 2022; and corn prices, as reported by the CME, ranged from $3.62 to $4.71 per bushel during 2024, from $4.50 to $6.85 per bushel during 2023 and from $5.64 to $8.18 per bushel during 2022.

Climate-Related and Other Risks

Short- to medium-term climate-related and other risks include high sensitivity to certain commodity prices such as corn and natural gas; regulatory changes and political volatility, both domestic and international; ethanol supply and demand imbalances; logistics and storage constraints from river access during inclement or volatile weather conditions; lack of automation of process optimization; high repair, maintenance and production costs resulting from older facilities; poor cooling capacity of our older facilities as water temperatures increase; and international market competition.

Long-term climate-related risks include water resource limitations; lower or volatile grain availability in local markets; market transition away from combustion fuels that include renewables; and the energy cost impact of technology such as wet milling and multiple distillation processes for high-quality alcohol. We also may be impacted by costs and regulatory burdens associated with carbon emissions from our production and distribution as well as truck transport and packaging associated with Eagle Alcohol’s use of drums and totes. See “Risk Factors.”

Marketing Arrangements

We market all the alcohols and essential ingredients produced at our facilities. We also market and distribute alcohols produced by third parties.

Competition

We are a leading producer of specialty alcohols in the United States.

Other significant producers of specialty alcohols in the United States are Archer-Daniels-Midland Company, Grain Processing Corporation, BioUrja Renewables, LLC, CIE and Greenfield Global Inc., which collectively make up a significant majority of the total installed specialty alcohol production capacity in the United States along with many smaller producers.

The largest producers of fuel-grade ethanol in the United States are POET, LLC, Valero Renewable Fuels Company, LLC, Archer-Daniels-Midland Company and Green Plains Inc., collectively with approximately 39% of the total installed fuel-grade ethanol production capacity in the United States. In addition, there are many mid-sized fuel-grade ethanol producers with several plants under ownership, smaller producers each with one or two plants, and several fuel-grade ethanol marketers that create significant competition. Overall, we believe there are over 200 fuel-grade ethanol production facilities in the United States with a total installed production capacity of approximately 18 billion gallons and many brokers and marketers with whom we compete for sales of fuel-grade ethanol and its co-products.

Our fuel-grade ethanol also competes on a global market against production from other countries, such as Brazil, which may have lower production costs than United States producers. Lower feedstock input costs such as sugarcane used in Brazil as compared to corn used in the Unites States may give foreign producers a competitive advantage. In addition, fuel-grade ethanol from sugarcane feedstock qualifies as an advanced biofuel, unlike corn ethanol, allowing certain producers to economically satisfy an advanced biofuel standard. Moreover, new products and production technologies are under continuous development, many of which, if adopted by competitors, could harm our ability to compete.

We believe that our competitive strengths include our customer and supplier relationships, our diverse product mix, the barriers to entry to our most profitable lines of business—including our certifications at our production facilities—our experienced management, and the strategic location of our Midwest production facilities. See “—Competitive Strengths.”

Governmental Regulation

Our business is subject to a wide range of federal, state and local laws and regulations directed at protecting public health and the environment, including those promulgated by the Occupational Safety and Health Administration, or OSHA, the U.S. Food and Drug Administration, or FDA, the EPA, and numerous state, local and international authorities. These laws, their underlying regulatory requirements and their potential enforcement, some of which are described below, impact, or may impact, nearly every aspect of our operations, including our alcohol production (including distillation), our liquid CO₂ production, our essential ingredient production, our storage facilities, and our water usage, wastewater discharge, disposal of hazardous wastes and emissions, and other matters pertaining to our existing and proposed business by imposing:

In addition, some governmental regulations are helpful to our production and marketing business. The fuel-grade ethanol industry in particular is supported by federal and state mandates and environmental regulations that favor the use of fuel-grade ethanol in motor fuel blends in North America. Some of the governmental regulations applicable to our production and marketing business are briefly described below.

Food and Drug Regulation

Our products for the Health, Home & Beauty, Food & Beverage and Essential Ingredients markets are subject to regulation by the FDA as well as similar state agencies. Under the Federal Food, Drug, and Cosmetic Act, or FDCA, the FDA regulates the processing, formulation, safety, manufacture, packaging, labeling and distribution of food ingredients, vitamins, cosmetics and pharmaceuticals for active and inactive ingredients. In 2022, The Modernization of Cosmetics Regulation Act (MoCRA) was added to the FDCA. This was a significant expansion to the FDCA, and established requirements for cosmetic product facility registration and product listing, widening regulatory oversight of many more of our customers’ products. Many of the FDA’s and FDCA’s rules and regulations apply directly to us as well as indirectly through their application in our customers’ products. For proper marketing and sale in the United States, an applicable product must be generally recognized as safe, approved and not adulterated or misbranded under the FDCA and relevant regulations issued under the FDCA. The FDA has broad authority to enforce the provisions of the FDCA. Failure to comply with the laws and regulations of the FDA or similar state agencies could prevent us from selling certain of our products or subject us to liability.

Renewable Fuels Energy Legislation

Under the RFS, the mandated use of all renewable fuels, including fuel-grade ethanol, rose incrementally and peaked at 36.0 billion gallons in 2022, of which 15.0 billion gallons are required from conventional, or corn-based, ethanol for 2025. Under the provisions of the Energy Independence and Security Act of 2007, the EPA has the authority to waive the mandated RFS requirements in whole or in part. To grant a waiver, the EPA administrator must determine, in consultation with the Secretaries of Agriculture and Energy, that there is inadequate domestic renewable fuel supply or implementation of the requirement would severely harm the economy or environment of a state, region or the United States as a whole.

Various bills in Congress introduced from time to time are also directed at altering existing renewable fuels energy legislation, but none have passed in recent years. Some legislative bills are directed at halting or reversing expansion of, or even eliminating, the renewable fuel program, while other bills are directed at bolstering the program or enacting further mandates or grants that would support the renewable fuels industry.

The EPA has allowed fuel and fuel-additive manufacturers to introduce into commercial gasoline up to 15% fuel-grade ethanol by volume, or E15, for vehicles from model year 2001 and after. According to the Renewable Fuels Association, E15 is explicitly approved by the manufacturer for use in approximately 95% of model year 2024 and newer cars and light trucks based on its annual review of vehicle owner’s manuals and warranty statements. Commercial sales of E15 have begun in a majority of states. E15 has historically been prohibited in most states during the summer driving season due to concerns over evaporative emissions and to meet federal clean air standards. For the 2024, 2023 and 2022 summer driving seasons, the EPA issued emergency fuel waivers to allow the sale of E15 to help alleviate high gasoline prices. E15 may, however, be sold year-round in states that have a reformulated gasoline program. In addition, the EPA proposed in late 2023 that E15 be permitted for sale year-round in various Midwestern states effective in April 2024. The U.S. Office of Management and Budget approved the proposal in February 2024 but deferred the effective date to April 2025.

Various states including California, Oregon and Washington, and other regions such as the Canadian province of British Columbia, have implemented low carbon fuel standards focused on reducing the carbon intensity of transportation fuels. Other states, including New York, Vermont, Massachusetts, Michigan, Illinois, Colorado and New Mexico, currently have proposed legislation or policies that would establish a low carbon fuel standard program. Blending fuel-grade ethanol into gasoline is one of the primary means of attaining these goals.

Additional Environmental Regulations

In addition to the governmental regulations applicable to the alcohol production and marketing industry described above, our business is subject to additional federal, state and local environmental regulations, including regulations established by the EPA and state regulatory agencies related to water quality and air pollution control. We cannot predict the manner by which, or extent to which, these regulations will harm or help our business or the alcohol production and marketing industry in general.

Human Capital Resources

As of March 12, 2025, we had approximately 393 full-time employees. Our human capital resources objectives include attracting and retaining well-qualified and highly skilled and motivated employees and executives. As of that same date, approximately 51% of our employees were represented by a labor union and covered by a collective bargaining agreement. We have never had a work stoppage or strike and we consider our relations with our employees to be good.

Our compensation program is designed to attract, retain and motivate our personnel. We use a mix of competitive salaries and other benefits to attract and retain employees and executives. Some of these benefits include matching 401K contributions of up to 6% of salary, health and wellness programs and a paid service day for employees to give back to their communities. At the direction and with the involvement of our Sustainability and Governance board committees, we have established a Sustainability working committee that draws from our many administrative and operational departments to review key policies and procedures, conduct employee engagement surveys, champion volunteering and charitable drives, develop and implement formalized recruiting and training efforts to prioritize collecting data and improving on key metrics from industry frameworks such as the Global Reporting Initiative (GRI) and Sustainability Accounting Standards Board (SASB) standards which are maintained by the International Sustainability Standards Board of the IFRS Foundation.

Item 1A. Risk Factors.

Before deciding to purchase, hold or sell our common stock, you should carefully consider the risks described below in addition to the other information contained in this Report and in our other filings with the Securities and Exchange Commission, including subsequent reports on Forms 10-Q and 8-K. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business. If any of these known or unknown risks or uncertainties actually occurs with material adverse effects on Alto Ingredients, our business, financial condition, results of operations and/or liquidity could be seriously harmed. In that event, the market price for our common stock will likely decline, and you may lose all or part of your investment.

Risks Related to our Business

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.

Our results of operations are highly impacted by commodity prices, including the cost of corn, natural gas and other production inputs that we must purchase, and the prices of alcohols and essential ingredients that we sell. Prices and supplies are subject to and determined by numerous market and other forces over which we have no control, such as inclement or favorable weather, domestic and global demand, supply excesses or shortages, export conditions, inflationary conditions, global geopolitical tensions and various governmental policies in the United States and throughout the world.

Price volatility of corn, natural gas and other production inputs, and alcohols and essential ingredients, may cause our results of operations to fluctuate significantly. We may fail to generate expected levels of net sales and profits even under fixed-price and other contracts for the sale of specialty alcohols used in consumer products. Our customers may not pay us timely or at all, even under longer-term, fixed-price contracts for our specialty alcohols, and may seek to renegotiate prices under those contracts during periods of falling prices or high price volatility.

Historically, the spread between corn and fuel-grade ethanol prices has fluctuated significantly. Fluctuations are likely to continue to occur. A sustained negative or narrow spread, whether as a result of sustained high or increased corn prices or sustained low or decreased alcohol or essential ingredient prices, would adversely affect our results of operations and financial condition. Revenues from sales of alcohols, particularly fuel-grade ethanol, and essential ingredients have in the past and could in the future decline below the marginal cost of production, which have in the past and may again in the future force us to suspend production, particularly fuel-grade ethanol production, at some or all of our facilities. For example, we hot-idled our Magic Valley facility in early 2023 due to unfavorable market conditions and again hot-idled our Magic Valley facility in early 2024 in part due to unfavorable market conditions and to expedite the installation of additional equipment needed to achieve the intended production rate, quality and consistency from the corn oil and high protein system at the facility. We restarted the Magic Valley facility in July 2024, but due to challenging market economics, we cold-idled the plant at the end of 2024.

In addition, some of our fuel-grade ethanol marketing and distribution activities will likely be unprofitable in a market of generally declining prices due to the nature of our business. For example, to satisfy customer demand, we maintain certain quantities of fuel-grade ethanol inventory for subsequent resale. Moreover, we procure much of our fuel-grade ethanol inventory outside of contracted third-party marketing and distribution arrangements and therefore must buy fuel-grade ethanol at a price established at the time of purchase and sell fuel-grade ethanol at an index price established later at the time of sale that is generally reflective of movements in the market price of fuel-grade ethanol. As a result, our margins for fuel-grade ethanol sold in these transactions generally decline and may turn negative as the market price of fuel-grade ethanol declines.

We can provide no assurances that corn, natural gas or other production inputs can be purchased at or near current or any specific prices, or that our alcohols or essential ingredients will sell at or near current or any particular prices. Consequently, our results of operations and financial condition may be adversely affected by increases in the prices of corn, natural gas and other production inputs or decreases in the prices of our alcohols and essential ingredients.

The prices of our products are volatile and subject to large fluctuations, which may cause our results of operations to fluctuate significantly.

The prices of our products are volatile and subject to large fluctuations. For example, the market price of fuel-grade ethanol is dependent upon many factors, including the supply of ethanol and the price of gasoline, which is in turn dependent upon the price of petroleum which itself is highly volatile, difficult to forecast and influenced by a wide variety of global economic and geopolitical conditions, including decisions concerning petroleum output by the Organization of Petroleum Exporting Countries (OPEC) and their allies, an intergovernmental organization that seeks to manage the price and supply of oil on the global energy market. Other important factors that impact the price of petroleum include war and threats of war, attacks on or threats to shipping vessels as has recently occurred in the Red Sea, the consequent rerouting of supply lines to less direct or more expensive paths, and other supply chain disruptions.

Our fuel-grade ethanol sales are tied to prevailing spot market prices rather than long-term, fixed-price contracts. Fuel-grade ethanol prices, as reported by the Chicago Mercantile Exchange, ranged from $1.38 to $2.12 per gallon in 2024, from $1.58 to $2.67 per gallon in 2023 and from $2.00 to $2.88 per gallon in 2022. In addition, even under longer-term, fixed-price contracts for our specialty alcohols, our customers may seek to renegotiate prices under those contracts during periods of falling prices or high price volatility. Fluctuations in the prices of our products 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.

To partially offset the effects of production input and product price volatility, in particular, corn and natural gas costs and fuel-grade ethanol prices, we may enter into contracts to purchase a portion of our corn or natural gas requirements on a forward basis or fix the sale price of portions of our alcohol production. In addition, we may engage in other hedging transactions involving exchange-traded futures contracts for corn, natural gas and unleaded gasoline from time to time. The financial statement impact of these activities is dependent upon, among other things, the prices involved and our ability to sell sufficient products to use all of the corn and natural gas for which forward commitments have been made. We have recognized losses in the past, and may suffer losses in the future, from our hedging arrangements. For example, for the year ended December 31, 2023, we recognized net losses of $8.0 million related to the change in the fair values of hedging contracts.

Hedging arrangements also expose us to the risk of financial loss in situations where our counterparty to the hedging contract defaults on its contract or, in the case of exchange-traded contracts, where there is a change in the expected differential between the underlying price in the hedging agreement and the actual prices paid or received by us. In addition, our open contract positions may require cash deposits to cover margin calls, negatively impacting our liquidity. As a result, our hedging activities and fluctuations in the price of corn, natural gas, fuel-grade ethanol and unleaded gasoline may adversely affect our results of operations, financial condition and liquidity.

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.

Our business depends on the continuing availability of rail, road, port, storage and distribution infrastructure. In particular, due to limited storage capacity at some of our production facilities and other considerations related to production efficiencies, certain facilities depend on timely delivery of corn. Alcohol production also requires a significant and uninterrupted supply of other raw materials and energy, primarily water, electricity and natural gas. Local water, electricity and gas utilities may fail to reliably supply the water, electricity and natural gas that our production facilities need or may fail to supply those resources on acceptable terms. In the past, poor weather has caused disruptions in rail transportation, which slowed the delivery of fuel-grade ethanol and/or corn by rail to and from our facilities.

For example, in the first quarter of 2024, extreme cold weather conditions in January at our Pekin Campus restricted barge deliveries and increased standby fees. To manage inventory levels, we transported more product by rail, a higher cost mode of transportation. Cold weather conditions also required us to shift to lower margin feed products and reduced our production rates across our Pekin Campus, hindering our ability to produce specialty alcohol at full capacity. In the third quarter of 2023 we experienced unusually high unscheduled production downtime for repairs and maintenance which reduced sales volumes and profits. In 2022, a lightning strike at the utility servicing our Pekin Campus disrupted our operations, cutting power to our facilities and materially affecting our production, resulting in unexpected repair and maintenance costs, lost production and degradation in the quality of work-in-progress inventories.

Disruptions in production or distribution, whether caused by labor difficulties, unscheduled downtimes and other operational hazards inherent in the alcohol production industry, including equipment failures, fires, explosions, abnormal pressures, blowouts, pipeline ruptures, transportation accidents, climate change and natural disasters such as earthquakes, floods and storms, or other weather effects, or human error or malfeasance or other reasons, could prevent timely deliveries of corn or other raw materials and energy, and could delay transport of our products to market, and may require us to halt production at one or more production facilities, any of which could have a material adverse effect on our business, results of operations and financial condition.

Some of these operational hazards may also cause personal injury or loss of life, severe damage to or destruction of property and equipment or environmental damage, and may result in suspension of operations and the imposition of civil or criminal penalties. Our insurance may not fully cover the potential hazards described above or we may be unable to renew our insurance on commercially reasonable terms or at all.

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.

The prices of our alcohols and essential ingredients are highly impacted by competing third-party supplies of those products. In addition, if fuel-grade ethanol production margins improve, we anticipate that owners of production facilities operating at below capacity, or owners of idled production facilities, will increase production levels, thereby resulting in more abundant fuel-grade ethanol supplies and inventories. Increases in the supply of alcohols and essential ingredients may not be commensurate with increases in demand for alcohols and essential ingredients, thus leading to lower prices. Any of these outcomes could have a material adverse effect on 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.

We evaluate our long-lived assets annually for impairment or when circumstances indicate that the full carrying value of an asset may be unrecoverable. These evaluations rely on financial and other assumptions concerning the assets, any of which may not materialize in the future. For example, we recognized asset impairments of $24.8 million and $6.5 million for the years ended December 31, 2024 and 2023, respectively. We may recognize additional impairments of the values of our long-lived assets in the future based on then-prevailing financial and other circumstances. Impairments of our long-lived assets 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.

We produce our alcohols from corn. Moreover, our plants are constructed and operate primarily as corn-based alcohol production facilities. Competitors and other third parties have undertaken research to develop competing products to corn-based alcohols, and ethanol in particular, as well as new process technologies. These research efforts seek alternatives to corn-based ethanol and traditional process technologies aimed at improving real or perceived problems with the fuel, such as the carbon and energy intensity of its production, its lower energy content compared to gasoline and its hydrophobic nature resulting in water separation in transit or at other times. Competitors and other third parties may develop new alcohols and processes that improve on any of these or other real or perceived problems with corn-based alcohols, including ethanol. If viable competing products or new process technologies are developed and attract widespread or even modest adoption, we may be forced to modify our production facilities, including our process technologies, if possible, to transition in full or in part to these other products or process technologies to remain competitive. Modifying our production facilities may require expertise that our personnel may not possess and would likely require significant capital expenditures the funding for which we may not have. An inability to remain competitive due to the introduction and adoption of competing products or new process technologies, or significant costs associated with the adoption of new products and process technologies, would materially and adversely affect our business, financial condition and results of operations.

Inflation and sustained higher prices may adversely impact our results of operations and financial condition.

We have experienced adverse inflationary impacts on key production inputs, wages and other costs of labor, equipment, services, and other business expenses. In addition, we have experienced adverse inflationary impacts on our budgets and expenses for many of our in-process and planned capital projects. Inflation and its negative impacts could escalate in future periods. Even if inflation stabilizes or abates, the prices of key production inputs, wages and other costs of labor, equipment, services, and other business expenses, and for our capital projects, will likely remain at elevated levels. We may not be able to include these additional costs in the prices of the products we sell. As a result, inflation and sustained higher prices may have a material adverse effect on 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.

Our business is highly sensitive to commodity prices, in particular, the prices of corn and natural gas. Inclement weather from climate change, including extreme temperatures or drought, may adversely affect growing conditions, which may reduce available corn supplies, our primary production input, and other grain substitutes, driving up prices and thereby increasing our production input costs. In addition, governmental regulators may disfavor carbon-based energy sources, such as natural gas, leading to regulations that disincentivize their use or otherwise make their production more difficult and costly, driving up their prices. Higher natural gas prices would likewise increase our production input costs.

Other factors that may result from climate change, or that may result from governmental regulations aimed at addressing climate-related issues, may also adversely affect our business, including the following:

New legislation in the United States to address climate change issues, especially at the state and local levels, may be passed and implemented, materially and adversely impacting our business.

Any of these factors 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 have incurred significant losses and negative operating cash flow in the past. For example, for the years ended December 31, 2024, 2023 and 2022, we incurred consolidated net losses of approximately $59.0 million, $28.0 million and $41.6 million, respectively. For the year ended December 31, 2024, we incurred negative operating cash flow of $3.5 million. We may incur losses and negative operating cash flow in the future. We expect to rely on cash on hand, cash, if any, generated from our operations, borrowing availability under our lines of credit and proceeds from our future financing activities, if any, to fund all of the cash requirements of our business. Additional losses and negative operating cash flow may hamper our operations and impede us from expanding our business.

We are engaged in multiple capital improvement projects. These 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, including as to projected additional EBITDA and Adjusted EBITDA.

We are engaged in multiple capital improvement projects to diversify and enhance our revenue streams and to expand margins and profitability by reducing costs. These projects have different timelines, returns on investment and risk profiles. In addition, we must raise significant additional capital to complete some of our projects, including our CCS project. Our expected financial and other results from these projects are based on assumptions around many factors, including their costs, timing, operation and market prices prevailing at project completion and thereafter, as well as tax and other favorable environmental attributes associated with low carbon alcohol that may accrue to our benefit. For example, our assumptions around the anticipated results of our CCS project rely heavily on the tax benefits that may accrue to us under the Inflation Reduction Act of 2022 as well as other favorable environmental attributes associated with carbon capture and storage and low carbon alcohol production. These tax and other benefits may change, including as a result of new or repealed laws, new administrations and the implementation or interpretation of existing laws, or the exhaustion of funds or benefits available under a particular program. For example, in January 2025, the new administration suspended all Inflation Reduction Act spending for 90 days. In addition, certain provisions of the Inflation Reduction Act lack proposed or final regulations and guidance. Regulators could issue new regulations or guidance that significantly narrows the application of clean energy tax incentives, and could even defer or withdraw regulations, which could materially and adversely affect the economic outcome of our CCS project. We can provide no assurances that any particular benefit will be available to us upon completion of our CCS project, or thereafter, or any other capital improvement project.

Capital improvement projects require significant outlays of capital and are often subject to material execution risks and delays. Our CCS project in particular requires Environmental Protection Agency, or EPA, approval but the EPA’s own projected timeline for approval has lengthened and may lengthen further. We may have insufficient financial resources, and we may be unable to raise sufficient capital, to complete our projects timely or at all. Although we intend to use reputable third-party contractors with expertise in their fields to implement our projects, adverse conditions and events as well as delays in capital projects are not uncommon. Moreover, the projects’ interaction with existing processes may result in the degradation of other plant operations. For example, operation of our corn oil and high protein system at our Magic Valley facility previously resulted in inconsistent product quality and degraded other operations at the plant, including production rates. In the past, we have extended our expected completion dates for various projects and, as circumstances require, may have to do so again.

In addition, our CCS project may be adversely affected by the SAFE CCS Act or the United States Supreme Court’s decision in the case of Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc., or both, as discussed below. The timing and economics of our CCS project may also be adversely affected by new rules proposed by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration that impose stronger standards for CO₂ pipelines and establish new standards for transporting CO₂ in a gaseous state via pipeline, adding additional requirements and costs to the project.

We can provide no assurances that our projects will be completed, or if completed, will be completed timely or within budget. We also can provide no assurances that our project assumptions will reflect prevailing future conditions or that our projects will achieve the results we expect, including as to projected additional EBITDA and Adjusted EBITDA. Failure to achieve our expected results may have a material adverse effect on our business, financial condition and results of operations.

We regularly incur significant expenses to repair, maintain and upgrade our production facilities and operating equipment, and any interruption in our operations would harm our operating performance.

We regularly incur significant expenses to repair, maintain and upgrade our production facilities and operating equipment, estimated at an average of $30.0 million per year. We incurred $35.0 million of these expenses for 2024. The machines and equipment we use to produce our alcohols and essential ingredients are complex, have many parts, and some operate on a continuous basis. We must perform routine equipment maintenance and must periodically replace a variety of parts such as motors, pumps, pipes and electrical parts, and engage in other repairs. In addition, our production facilities require periodic shutdowns to perform major maintenance and upgrades. Our production facilities also occasionally require unscheduled shutdowns to perform repairs. For example, we completed our biennial wet mill outage at our Pekin Campus in Spring 2024. The wet mill was offline for ten days, which negatively impacted sales and margins for the second quarter. In the first quarter of 2024, production at our Colombia facility was hampered by equipment issues that extended the facility’s regularly scheduled outage. In the third quarter of 2023 we experienced unusually high unscheduled production downtime for repairs and maintenance at our Pekin Campus which reduced sales volumes and increased losses. These scheduled and unscheduled shutdowns result in lower sales and increased costs in the periods during which a shutdown occurs and could result in unexpected operational issues in future periods resulting from changes to equipment and operational and mechanical processes made during shutdown.

Our indebtedness may expose us to risks that could negatively impact our business, prospects, liquidity, cash flows and results of operations.

We have incurred, and anticipate incurring additional, substantial indebtedness for our capital improvement projects. We expect that these projects, when completed, will generate financial returns sufficient to service and ultimately repay or refinance our indebtedness. However, the costs, timing, and effects of our capital improvement projects may not meet our projections. In addition, our indebtedness could:

Our ability to generate operating results and sufficient cash to make all required principal and interest payments when due, and to satisfy our financial covenants and other obligations, depends on our performance, which is subject to a variety of factors beyond our control, including the cost of key production inputs, the supply of and demand for alcohols and essential ingredients, and many other factors related to the industries in which we operate. We cannot provide any assurance that we will be able to timely service or satisfy our debt obligations, including our financial covenants. Our failure to timely service or satisfy our debt obligations, including to meet our financial covenants, could result in our indebtedness being immediately due and payable, and would have a material adverse effect on our business, business prospects, liquidity, financial condition, cash flows and results of operations.

Our ability to utilize net operating loss carryforwards and certain other tax attributes may be limited.

Federal and state income tax laws impose restrictions on our use of net operating loss, or NOL, and tax credit carryforwards in the event that an “ownership change” occurs for tax purposes, as defined by section 382 of the Internal Revenue Code, or Code. In general, an ownership change occurs when stockholders owning 5% or more of a corporation entitled to use NOL or other loss carryforwards have increased their ownership by more than 50 percentage points during any three-year period. The annual base limitation under section 382 of the Code is calculated by multiplying the corporation’s value at the time of the ownership change by the greater of the long-term tax-exempt rate determined by the Internal Revenue Service in the month of the ownership change or the two preceding months. Our ability to utilize our NOL and other loss carryforwards may be substantially limited. These limitations could result in increased future tax obligations, which could have a material adverse effect on our financial condition and results of operations.

Risks Related to Legal and Regulatory Matters

We may be adversely affected by environmental, health and safety laws and regulations, as well as related liabilities that may not be adequately covered by insurance.

We are subject to various federal, state and local environmental laws and regulations, including those relating to the discharge of materials into the air, water and ground; the generation, storage, handling, use, transportation and disposal of hazardous materials and wastes; and the health and safety of our employees. In addition, some of these laws and regulations require us to operate under permits that are subject to renewal or modification. These laws, regulations and permits often require expensive pollution control equipment or operational changes to limit actual or potential impacts to the environment. Any violation of these laws and regulations or permit conditions may result in substantial fines, natural resource damages, criminal sanctions, permit revocations and/or production facility shutdowns. In addition, we have made, and expect to make, significant capital expenditures on an ongoing basis to comply with increasingly stringent environmental laws, regulations and permits.

We may be liable for the investigation and cleanup of environmental contamination at each of our production facilities and at off-site locations where we arrange for the disposal of hazardous substances or wastes. If these substances or wastes have been or are disposed of or released at sites that undergo investigation and/or remediation by regulatory agencies, we may be responsible under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, or other environmental laws for all or part of the costs of investigation and/or remediation, and for damages to natural resources. We may also be subject to related claims by private parties alleging property damage and personal injury due to exposure to hazardous or other materials at or from those properties. Some of these matters may require us to expend significant amounts for investigation, cleanup or other costs not covered by insurance.

In addition, new laws, new interpretations of existing laws, increased governmental enforcement of environmental laws or other developments could require us to make significant additional expenditures. Continued government and public emphasis on environmental issues will likely result in increased future investments for environmental controls at our production facilities. Present and future environmental laws and regulations, and interpretations of those laws and regulations, applicable to our operations, more vigorous enforcement policies and discovery of currently unknown conditions may require substantial expenditures that could have a material adverse effect on our results of operations and financial condition.

The hazards and risks associated with producing and transporting our products (including fires, natural disasters, explosions and abnormal pressures and blowouts) may also result in personal injury claims or damage to property and third parties. As protection against operating hazards, we maintain insurance coverage against some, but not all, potential losses. However, we could sustain losses for uninsurable or uninsured risks, or in amounts in excess of existing insurance coverages. Events that result in significant personal injury or damage to our property or third parties or other losses that are not fully covered by insurance could have a material adverse effect on our results of operations and financial condition.

Our CCS project may be adversely affected by the SAFE CCS Act and other Regulations.

The SAFE CCS Act was signed into law in Illinois in July 2024. We are pursuing at our Pekin Campus, located in Illinois, a CCS project that will require significant financial and personnel resources. Our CCS project is our most important ongoing capital improvement initiative. The SAFE CCS Act establishes stringent safety, financial and insurance requirements on CO₂ pipelines and imposes a moratorium on the construction of new CO₂ pipelines until the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration finalizes its new safety rules or July 1, 2026, whichever occur sooner. The SAFE CCS Act will result in increased compliance and other requirements likely adding costs and potentially adding time to complete our CCS project. In January 2025, the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration proposed new rules that impose stronger standards for CO₂ pipelines and establish new standards for transporting CO₂ in a gaseous state via pipeline, adding additional requirements and costs to the project. We can provide no assurance that our CCS project will not be adversely affected by the SAFE CCS Act or other regulations or that it will be financially viable in light of any new requirements and potential delays.

We may be adversely affected by food and drug laws and regulations, as well as related liabilities that may not be adequately covered by insurance.

Some of our products are subject to regulation by the U.S. Food and Drug Administration, or FDA, as well as similar state agencies. The FDA regulates, under the Federal Food, Drug, and Cosmetic Act, or FDCA, the processing, formulation, safety, manufacture, packaging, labeling and distribution of food ingredients, vitamins, cosmetics and pharmaceuticals for active and inactive ingredients. Many of the FDA’s and FDCA’s rules and regulations apply directly to us as well as indirectly through their application in our customers’ products. To be properly marketed and sold in the United States, a relevant product must be generally recognized as safe, approved and not adulterated or misbranded under the FDCA and relevant regulations issued under the FDCA.

If we fail to comply with laws and FDA regulations or those of similar state agencies, we may be prevented from selling certain of our products and may also be subject to government agency enforcement liability. In addition, we may be subject to product liability and other claims by our customers or by individuals alleging personal injury from our products as food and drug additives.

We maintain insurance coverage against some, but not all, potential losses. Some of these matters, if they arise, may require us to expend significant amounts for investigation and defense or other costs not covered by insurance. We could sustain losses for uninsurable or uninsured risks, or in amounts in excess of existing insurance coverages. Events that result in significant personal injury or other losses that are not fully covered by insurance could have a material adverse effect on our results of operations and financial condition.

The United States fuel-grade ethanol industry is highly dependent upon various federal and state laws and regulations and any changes in or reinterpretations of those laws or regulations could have a material adverse effect on our results of operations, cash flows and financial condition.

The domestic market for fuel-grade ethanol is significantly impacted by federal mandates for volumes of renewable fuels (such as ethanol) required to be blended with gasoline. Future demand for fuel-grade ethanol will largely depend on incentives to blend ethanol into motor fuels, including the price of ethanol relative to the price of gasoline, the relative octane value of ethanol, constraints on the ability of vehicles to use higher ethanol blends, and the EPA’s, established volumes from time to time, small refinery waivers, and other applicable environmental requirements.

The EPA has implemented the Renewable Fuel Standard under the Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007. The EPA, in coordination with the Secretary of Energy and the Secretary of Agriculture, determines annual quotas for the quantity of renewable fuels (such as fuel-grade ethanol) that must be blended into motor fuels consumed in the United States. The EPA finalized mandatory volumes of 15.0 billion gallons for each of 2023, 2024, and 2025 of conventional renewable fuels, or corn-based fuel-grade ethanol, which could decline in future years.

The EPA may issue small refinery waivers, in full or in part, to reduce or eliminate annual renewable fuel volume requirements for small refineries that process fewer than 75,000 barrels of petroleum daily. In the past, the EPA has issued small refinery waivers that have materially and adversely affected overall demand for and the price of fuel-grade ethanol. The U.S. Court of Appeals for the Fifth Circuit, in the fourth quarter of 2023, struck down the EPA’s decision to deny numerous small refinery waivers, finding that the EPA’s denials were impermissibly retroactive, contrary to law and counter to evidence in the litigation record. Accordingly, small refinery waivers from the EPA may be more likely in the future and could again materially and adversely affect overall demand for and the price of fuel-grade ethanol.

Various bills in Congress introduced from time to time are also directed at altering existing renewable fuels energy legislation, but none have passed in recent years. Some legislative bills are directed at halting or reversing expansion of, or even eliminating in its entirety, the renewable fuel program.

Our results of operations, cash flows and financial condition could be adversely impacted if the EPA reduces mandatory volumes or issues significant small refinery waivers, or if any legislation is enacted that reduces volume requirements or if existing legislation is reinterpreted to have the same effect.

Future demand for fuel-grade ethanol is uncertain and may be affected by changes to federal mandates, public perception, consumer acceptance and overall consumer demand for transportation fuel, any of which could negatively affect demand for fuel-grade ethanol and our results of operations.

Although many trade groups, academics and governmental agencies support ethanol as a fuel additive that promotes a cleaner environment, others criticize fuel-grade ethanol production and use as consuming considerably more energy and emitting more greenhouse gases than other biofuels and potentially depleting water resources. Some studies suggest that corn-based ethanol is less efficient than ethanol produced from other feedstock and that it negatively impacts consumers by causing increased prices for dairy, meat and other food generated from livestock that consume corn. Additionally, critics of fuel-grade ethanol contend that corn supplies are redirected from international food markets to domestic fuel markets. If negative views of corn-based ethanol production gain broader acceptance, support for existing measures promoting use and domestic production of corn-based ethanol as a fuel additive could decline, leading to a reduction or repeal of federal ethanol usage mandates, which would materially and adversely affect the demand for fuel-grade ethanol. These views could also negatively impact public perception of the fuel-grade ethanol industry and acceptance of ethanol as an alternative fuel.

There are limited markets for fuel-grade ethanol beyond those established by federal mandates. Discretionary blending and E85 blending (i.e., gasoline blended with up to 85% fuel-grade ethanol by volume) are important secondary markets. Discretionary blending is often determined by the price of fuel-grade ethanol relative to the price of gasoline. In periods when discretionary blending is financially unattractive, the demand for fuel-grade ethanol may decline. Also, the demand for fuel-grade ethanol is affected by the overall demand for transportation fuel. Demand for transportation fuel is affected by the number of miles traveled by consumers and vehicle fuel economy. Lower demand for fuel-grade ethanol and essential ingredients, including through the transition by consumers to alternative fuel vehicles such as electric vehicles and hybrid vehicles, would reduce the value of our ethanol and related products, erode our overall margins and diminish our ability to generate revenue or to operate profitably. In addition, we believe that additional consumer acceptance of E15 and E85 fuels is necessary before fuel-grade ethanol can achieve any significant growth in market share relative to other transportation fuels.

The United States Supreme Court’s decision in the case of Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc. may result in less industry-favorable rulemaking and agency interpretations of laws and regulations, which could materially and adversely affect our results of operations, cash flows and financial condition as well as the business and financial prospects of certain capital improvement projects, such as CCS.

The United States Supreme Court, in the landmark case of Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc., recently overturned its prior doctrine of judicial deference to administrative interpretations of laws and regulations. This outcome could materially and adversely affect rulemaking and agencies’ interpretations favorable to the renewable fuels industry, such as the EPA’s administration of the Renewable Fuel Standard. This outcome could also materially and adversely affect the Treasury Department’s ability to promulgate favorable regulations under the Inflation Reduction Act of 2022, including tax credits such as the section 45Q carbon capture and storage tax credits and section 45Z low carbon fuel tax credits, as well as other industry-favorable tax credits. Less industry-favorable rulemaking and agency interpretations of laws and regulations could materially and adversely affect our results of operations, cash flows and financial condition as well as the financial prospects of certain capital improvement projects, such as CCS.

Risks Related to Ownership of our Common Stock

Our stock price is highly volatile, which could result in substantial losses for investors purchasing shares of our common stock and in litigation against us.

The market price of our common stock has fluctuated significantly in the past and may continue to fluctuate significantly in the future. The market price of our common stock may continue to fluctuate in response to one or more of the following factors, or any of the other risks or uncertainties discussed in this report, many of which are beyond our control:

The price at which you purchase shares of our common stock may not be indicative of the price that will prevail in the trading market. You may be unable to sell your shares of common stock at or above your purchase price, which may result in substantial losses to you and which may include the complete loss of your investment. In the past, securities class action litigation has often been brought against a company following periods of high stock price volatility. We may be the target of similar litigation in the future. Securities litigation could result in substantial costs and divert management’s attention and our resources away from our business.

Any of the risks described above could have a material adverse effect on our results of operations, the price of our common stock, or both.

Because we do not plan to pay any cash dividends on our shares of common stock, our stockholders will not be able to receive a return on their shares unless and until they sell them.

We intend to retain a significant portion of any future earnings to finance the development, operation and expansion of our business. We do not anticipate paying any cash dividends on our common stock in the near future. The declaration, payment, and amount of any future dividends will be made at the discretion of our board of directors, and will depend upon, among other things, our results of operations, cash flows, and financial condition, operating and capital requirements, compliance with any applicable debt covenants, and other factors our board of directors considers relevant. There is no assurance that future dividends will be paid, and, if dividends are paid, there is no assurance of the amount of any such dividend. Unless our board of directors determines to pay dividends, our stockholders will be required to look solely to appreciation in the value of our common stock to realize any gain on their investment. There can be no assurance that any such appreciation will occur.

Our bylaws contain exclusive forum provisions that could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Delaware Court of Chancery shall be the sole and exclusive forum for (a) any derivative action or proceeding brought on our behalf, (b) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of us to us or our stockholders, (c) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, or (d) any action asserting a claim governed by the internal affairs doctrine.

Our bylaws also provide that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by applicable law, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended, or the Securities Act, including all causes of action asserted against any defendant named in such complaint, including our officers and directors, underwriters for any offering giving rise to such complaint, and any other professional entity whose profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying the offering.

For the avoidance of doubt, the exclusive forum provisions described above do not apply to any claims arising under the Securities Act or the Securities Exchange Act of 1934, as amended, or the Exchange Act, to the extent federal law requires otherwise. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder, and Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

The choice of forum provisions in our bylaws may limit our stockholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with us or our directors, officers, employees, agents or other third parties, which may discourage such lawsuits against us and our directors, officers, employees, agents and other third parties even though an action, if successful, might benefit our stockholders. The applicable courts may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. With respect to the provision making the Delaware Court of Chancery the sole and exclusive forum for certain types of actions, stockholders who do bring a claim in the Delaware Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. Finally, if a court were to find these provisions of our bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could have a material adverse effect on us.

General Risk Factors

Cyberattacks through security vulnerabilities could lead to disruption of our business, reduced revenue, increased costs, liability claims, or harm to our reputation or competitive position.

Security vulnerabilities may arise from our hardware, software, employees, contractors or policies we have deployed, which may result in external parties gaining access to our networks, data centers, cloud data centers, corporate computers, manufacturing systems, and/or access to accounts we have at our suppliers, vendors or customers. External parties may gain access to our data or our customers’ data, or attack the networks causing denial of service or attempt to hold our data or systems in ransom. The vulnerability could be caused by inadequate account security practices such as the failure to timely remove employee access when terminated. To mitigate these security issues, we have implemented measures throughout our organization, including firewalls, backups, encryption, employee information technology policies and user account policies. However, there can be no assurance that these measures will be sufficient to avoid cyberattacks. If any of these types of security breaches were to occur and we were unable to protect sensitive data, our relationships with our business partners and customers could be materially damaged, our reputation could be materially harmed, and we could be exposed to a risk of litigation and possible significant liability.

Further, if we fail to adequately maintain our information technology infrastructure, we may have outages and data loss. Excessive outages may affect our ability to timely and efficiently deliver products to customers or develop new products. Such disruptions and data loss may adversely impact our ability to fulfill orders and interrupt other processes. Delayed sales or lost customers resulting from these disruptions could adversely affect our financial results, stock price and reputation.

Our and our business partners’ or contractors’ failure to fully comply with applicable data privacy or similar laws could lead to significant fines and require onerous corrective action. In addition, data security breaches experienced by us or our business partners or contractors could result in the loss of trade secrets or other intellectual property, public disclosure of sensitive commercial data, and the exposure of personally identifiable information (including sensitive personal information) of our employees, customers, suppliers, contractors and others.

Unauthorized use or disclosure of, or access to, any personal information maintained by us or on our behalf, whether through breach of our systems, breach of the systems of our suppliers or vendors by an unauthorized party, or through employee or contractor error, theft or misuse, or otherwise, could harm our business. If any such unauthorized use or disclosure of, or access to, such personal information was to occur, our operations could be seriously disrupted, and we could be subject to demands, claims and litigation by private parties, and investigations, related actions, and penalties by regulatory authorities. In addition, we could incur significant costs in notifying affected persons and entities and otherwise complying with the multitude of foreign, federal, state and local laws and regulations relating to the unauthorized access to, or use or disclosure of, personal information. Finally, any perceived or actual unauthorized access to, or use or disclosure of, such information could harm our reputation, substantially impair our ability to attract and retain customers and have an adverse impact on our business, financial condition and results of operations.

Item 1B. Unresolved Staff Comments.

We have received no written comments regarding our periodic or current reports from the staff of the Securities and Exchange Commission that were issued 180 days or more preceding the end of our 2024 fiscal year and that remain unresolved.

Item 1C. Cybersecurity.

Engagement and Continuous Improvement

We periodically evaluate our cybersecurity measures through internal and external audits and assessments to ensure our cybersecurity program is at the forefront of industry best practices. The results of these audits and assessments inform adjustments to our cybersecurity program to improve our resilience against emerging cybersecurity threats.

Item 2. Properties.

Our corporate headquarters, located in Pekin, Illinois, consists of plants and facilities comprising our Pekin Campus production segment and totaling 145 acres on land we own. In Sacramento, California, we lease office space totaling approximately 3,400 square feet under a lease expiring in 2026. In St. Louis, Missouri, we lease warehouse space totaling approximately 84,000 square feet under a lease expiring in 2030. We have plants located in Boardman, Oregon, at a 25-acre facility, and Burley, Idaho, at a 25-acre facility. The land in Boardman, Oregon is leased under a lease expiring in 2076. We own the land in Burley, Idaho. The plants and facilities in Oregon and Idaho comprise our Western production segment. See “Business—Production Facilities.” Our properties are subject to deeds of trust and other encumbrances in favor of our lenders.

Item 3. 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.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and notes to consolidated financial statements included elsewhere in this report. This discussion contains forward-looking statements, reflecting our plans and objectives that involve risks and uncertainties. Actual results and the timing of events may differ materially from those contained in these forward-looking statements due to a number of factors, including those discussed in the section entitled “Risk Factors” and elsewhere in this report.

Overview

We are a leading producer and distributor of specialty alcohols, renewable fuels and essential ingredients in the United States.

We operate five alcohol production facilities. Three of our production facilities are located in Illinois, one is located in Oregon and another is located in Idaho. We have an annual alcohol production capacity of 350 million gallons, including both renewable fuels and specialty alcohols ranging from industrial-, pharmaceutical-, and high-quality food- and beverage-grade alcohols. Of this amount, we can produce up to 110 million gallons annually of specialty alcohols, depending on our product mix among high-quality beverage-grade alcohol and other quality specification alcohols. We market and distribute all of the alcohols produced at our facilities as well as alcohols produced by third parties. In 2024, we marketed and distributed approximately 386 million gallons combined of our own produced alcohols as well as fuel-grade ethanol produced by third parties, and over 1.4 million tons of essential ingredients on a dry matter basis.

We also own and operate a liquid CO₂ production facility adjacent to our plant in Oregon for the offtake of CO₂ gas from the plant for conversion to liquid CO₂ and subsequent sale.

In addition, we break bulk distribute specialty alcohols, produced by us and third parties, through our Eagle Alcohol business.

We report our financial and operating performance in three distinct segments:

Our mission is to produce the highest quality, sustainable ingredients that make everyday products better. We intend to accomplish this goal in part by investing in our specialized and higher value specialty alcohol production and distribution infrastructure, expanding production in high-demand essential ingredients, expanding and extending the sale of our products into new regional and international markets, building efficiencies and economies of scale and by capturing a greater portion of the value stream.

Production Segments

We produce specialty alcohols, renewable fuels and essential ingredients, focusing on five key markets: Health, Home & Beauty; Food & Beverage; Industry & Agriculture; Essential Ingredients; and Renewable Fuels. Products for Health, Home & Beauty markets include specialty alcohols used in mouthwash, cosmetics, pharmaceuticals, hand sanitizers, disinfectants and cleaners. Products for Food & Beverage markets include grain neutral spirits used in alcoholic beverages and vinegar and 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, distillers grains, liquid CO₂ and liquid feed used in commercial animal feed and pet foods. We also sell yeast and liquid CO₂ for human consumption. Our products for the Renewable Fuels markets include fuel-grade ethanol and distillers corn oil used as a feedstock for renewable diesel and biodiesel fuels. Our specialty alcohols for the Industry & Agriculture, Food & Beverage and Health, Home & Beauty markets represented approximately 12%, 7% and 3%, respectively, of our sales in 2024 from these three markets.

We produce our alcohols and essential ingredients at our facilities described below. Our production facilities located in Illinois are in the heart of the Corn Belt, benefit from relatively low-cost and abundant feedstock and enjoy logistical advantages that enable us to provide our products to both domestic and international markets via truck, rail or barge. Our production facilities located in Oregon and Idaho are near their respective fuel and feed customers, offering significant timing, product transportation cost and logistical advantages.

All of our production facilities, other than our Magic Valley plant, were operating for all of 2024, subject to scheduled and unscheduled downtimes to address facility repair and maintenance.

In January 2024, we temporarily hot-idled our 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 our corn oil and high protein system at the facility. We restarted our 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 we were able to expand our 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 our plant improvements. As a consequence, we cold-idled our Magic Valley facility on December 31, 2024 to minimize financial losses. We continue to provide terminal services at the plant and intend to resume operations at the facility when the economic environment in the region sustainably improves. We believe that the cold-idling of our Magic Valley facility will have a positive impact on our overall financial results in 2025 compared to 2024.

As market conditions change, we may increase, decrease or idle production at one or more operating facilities or resume operations at any idled facility.

Marketing and Distribution Segment

We market and distribute all the alcohols and essential ingredients we produce at our facilities. We also market and distribute alcohols produced by third parties.

We have extensive and long-standing customer relationships, both domestic and international, for our specialty alcohols, renewable fuels and essential ingredients. These customers include producers and distributors of ingredients for cosmetics, sanitizers and related products, distilled spirits producers, food products manufacturers, producers of personal health/consumer health and personal care hygiene products, and global trading firms.

Our renewable fuels customers are located throughout the Western and Midwestern United States and consist of integrated oil companies and gasoline marketers who blend fuel-grade ethanol into gasoline. Our customers depend on us to provide a reliable supply of fuel-grade ethanol and manage the logistics and timing of delivery. Our customers collectively require fuel-grade ethanol volumes in excess of the supplies we produce at our facilities. We secure additional fuel-grade ethanol supplies from third-party ethanol producers. We arrange for transportation, storage and delivery of fuel-grade ethanol purchased by our customers through our agreements with third-party service providers in the Western United States as well as in the Midwest from a variety of sources.

We market food-grade essential ingredients to human and pet food markets, our feed products (such as distillers grains) primarily to export markets from our Pekin Campus, and other feed products to dairies and feedlots, in many cases located near our production facilities. These customers use our feed products for livestock as a substitute for corn and other sources of starch and protein. We sell our corn oil to poultry, renewable diesel and biodiesel customers.

See “Note 4 – Segments” to our Notes to Consolidated Financial Statements included elsewhere in this report for financial information about our business segments.

Financial Review, Current Initiatives and Outlook

Our fourth quarter and full-year financial results reflect challenging market conditions, including lower crush margins, compared to the fourth quarter of 2023 and the prior full year. As discussed below, we took decisive action to rationalize our business which, together with over $30 million in associated asset impairments, resulted in a material portion of the substantial non-cash, one-time expenses for the fourth quarter and full year 2024, resetting our base. We also reduced our annual expense run rate by nearly $8 million. Together with improved performance at our Pekin Campus wet mill, our synergistic acquisition of premium liquid CO₂ processing and our entry into the European market through International Sustainability and Carbon Certification, or ISCC, product sales, we are optimistic about 2025.

As part of our ongoing efforts to maximize shareholder value, we have engaged an investment banking firm to explore the sale of our production facilities located in Oregon and Idaho. In addition, with the assistance of our financial and legal advisors, we are considering a broad range of other options, including asset sales, a merger or other strategic transactions to better align our long-term value potential.

In January, we acquired Kodiak Carbonic, a beverage-grade liquid CO₂ processor, for $7.6 million. This processing facility, renamed Alto Carbonic, is located adjacent to our Columbia plant in Boardman, Oregon and has been operating profitably since 2015.

Alto Carbonic processes biogenic CO₂ gas produced as a byproduct of the fermentation process at our Columbia plant and converts it into premium liquid CO₂. The finished product is sold into the Northwestern region of the United States for use in food and beverage processing, industrial cooling, and other applications. The facility produces an average of approximately 56,000 tons annually of liquid CO₂ with the capacity to produce over 70,000 tons annually and the potential for further expansion. Alto Carbonic currently uses only 50% of our Columbia plant’s biogenic CO₂ gas.

Simultaneous with this acquisition, we entered into an amended long-term sales offtake agreement with a leading North American industrial gas supplier. The acquisition is immediately accretive and has a compelling payback of approximately two years. We are in the process of integrating the liquid CO₂ plant with our Columbia facility, improving coordination between operations. We expect to realize additional cost savings through synergies in production and overhead. We are also evaluating an opportunity to increase storage capacity at the site to improve logistics and take advantage of spot market demand for premium liquid CO₂.

The acquisition immediately stems the recent lack of profitability at our Columbia plant, provides a stronger financial foundation to overcome competitive challenges for destination plants and significantly increases the value of these combined assets.

We integrated Eagle Alcohol’s high quality alcohol bulk operations and customers into our Pekin Campus and Kinergy businesses and have now turned our focus to converting Eagle Alcohol’s break-bulk warehousing and trucking operations into a profitable service center.

We also decreased staff at other operations, reducing overhead run-rates of both costs of goods sold and selling, general and administrative expenses. In total, we reduced headcount by 16% and expect to save nearly $8 million annually from these efficiencies, improving our bottom-line run rate and helping us manage our liquidity. We expect to realize the full annualized financial benefit from these cost saving initiatives beginning in the second quarter.

As an additional cost saving initiative, we cold-idled our Magic Valley facility at the end of 2024. For context, starting in 2022, we saw an opportunity to take advantage of premium prices for high quality protein and corn oil. Consistent with our business strategy to improve yields of high margin products, we undertook the installation and ultimate commissioning of high-quality protein and corn oil technology at our Magic Valley plant. The installation took much longer and cost significantly more than expected. In addition, we underestimated the negative impact that the buildout of renewable diesel and soy crush capacity would have on market prices for protein and corn oil in the region. Compounded by the dramatic swing in delivered corn prices for Western operations compared to our Midwestern facilities, it became impossible to operate our Magic Valley facility profitably. By cold idling the plant and reducing our variable and fixed costs as much as possible, we have stopped this drag on the profitable areas of our business. In the fourth quarter, we took a significant impairment charge related to the Magic Valley plant. To partially offset remaining carry expenses, and to serve our customers in the area, we are opportunistically using the facility as a renewable fuel terminal.

At our Pekin Campus, we continue to pursue opportunities to optimize carbon, which historically was considered a waste stream with only marginal value. In November, we achieved an important milestone by finalizing our CO₂ transportation and sequestration agreement with Vault 44.01, or Vault. This partnership is critical to our carbon capture and storage, or CCS, project. In December, Vault submitted the formal application to the EPA for our CCS project to obtain the Class VI permit required to begin construction of the CCS pipeline and for long-term CO₂ storage in deep geological formations.

CCS operations require significant development and planning. The EPA requires extensive site analysis, monitoring and safety measures to safeguard underground water supplies. The approval process is currently estimated to take at least two years. We expect that this approval timeline will also allow the time necessary to address Illinois’s current moratorium on new CO₂ pipelines imposed as part of its SAFE CCS Act. The moratorium is in effect until the earlier of July 2026 or revised federal safety standards are established.

Although progress on our CCS project has been slow, significant changes have occurred in the political and regulatory environment, as well as the carbon market, during that time. Our deliberate pace has been advantageous as we navigate these changes and discover effective paths forward. The extended period required for regulatory approvals affords us additional time to develop the necessary infrastructure plans, including compression and energy solutions. We also intend to use the additional time to secure necessary financing. Finally, working with Vault, we are focused on meeting with local groups and authorities to educate the community about our CCS project, strengthen support and address concerns.

At our Pekin Campus, we are proactively modifying our operations to deliver higher value products. Following our biennial wet mill outage in spring 2024, we improved plant utilization, operating the wet mill at nameplate capacity of 100 million gallons. Pekin Campus production volume in the fourth quarter increased 3.8 million gallons over the prior year period. This 7% increase demonstrates the effectiveness of our maintenance program. Carrying these improvements into 2025, we expect to produce an additional 8 million gallons for the full year, lowering our per gallon cost of production and enabling us to produce a greater volume of specialty alcohols.

We applied for, and in late summer obtained for our Pekin Campus, ISCC certification for our renewable fuels business to allow us to ship qualified renewable fuel to the European Union where we typically are able to garner premium prices compared to domestic markets. We began exporting certified renewable fuel to European markets in the fourth quarter and anticipate expanding exports in 2025.

In our premium specialty alcohol business, we continue to materially differentiate our products through our certifications and customer relationships. For 2024, we sold nearly 92 million gallons of specialty alcohols. In 2025, our goal is to balance production levels between specialty alcohols and ISCC renewable fuels to maximize margins while addressing customer needs. We also completed another ISO 9001 audit with no adverse findings, a testament to our culture of quality.

For the fourth quarter, we sold 95.1 million gallons, up from 92.5 million gallons for the same period in 2023, largely reflecting production improvements at our Pekin Campus from our planned repairs and maintenance program. However, our sales price per gallon averaged $1.88 in the fourth quarter compared to $2.24 for the same period in 2023, reducing net sales by $38 million for the year over year period. Market crush margins declined nearly 18 cents per gallon in the fourth quarter resulting in an $8.7 million adverse impact to gross profit for the period. In addition, returns from protein sales were negatively impacted by expanded soy crush intended to meet renewable diesel demand, higher wet feed product mix and the inability of a key customer to take product deliveries following Hurricane Helene. Low carbon fuel credit prices also declined in the fourth quarter compared to the prior year period but improved sequentially from the third quarter of 2024 and continue to recover from market lows.

Our realized derivative losses, which are included in Adjusted EBITDA (defined below), were $3.5 million for the fourth quarter compared to $2.3 million for the prior year period. Unrealized derivative gains, which are excluded from Adjusted EBITDA, were $5.5 million for the fourth quarter compared to a loss of $8.2 million for the prior year period, resulting in a positive $13.7 million year-over-year net difference. Our non-cash, lower of cost or market adjustment on physical inventories and mark-to-market on corn commitments resulted in a $3.5 million reserve in the fourth quarter compared to $2.2 million in the prior year period. In the fourth quarter, we recognized final acquisition-related expenses for Eagle Alcohol of $5.7 million, of which $5.0 million was non-cash, compared to $0.7 million in the prior year period.

Asset impairments for the fourth quarter totaled $24.8 million, consisting of $21.4 million related to the cold idling of our Magic Valley plant and $3.4 million related to the impairment of intangibles from the integration of certain Eagle Alcohol activities, compared to a $6.0 million impairment in the prior year period related to Eagle Alcohol’s goodwill.

Use of Non-GAAP Financial Measures

Management believes that certain financial measures not in accordance with generally accepted accounting principles, or GAAP, are useful measures of operations. Management provides EBITDA and Adjusted EBITDA as non-GAAP financial measures so that investors will have the same financial information that management uses, which may assist investors in properly assessing our performance on a period-over-period basis.

We define EBITDA as unaudited consolidated net income (loss) before interest expense, interest income, provision for income taxes and depreciation and amortization expense. We define Adjusted EBITDA as unaudited consolidated net income (loss) before interest expense, interest income, unrealized derivative gains and losses, acquisition-related expense, provision for income taxes, asset impairments, and depreciation and amortization expense.

A table is provided below to reconcile Adjusted EBITDA to its most directly comparable GAAP measure, consolidated net income (loss). EBITDA and Adjusted EBITDA are not measures of financial performance under GAAP and should not be considered as alternatives to consolidated net income (loss) or any other measure of performance under GAAP, or to cash flows from operating, investing or financing activities as an indicator of cash flows or as a measure of liquidity. EBITDA and Adjusted EBITDA have limitations as analytical tools and you should not consider these measures in isolation or as a substitute for analysis of our results as reported under GAAP.

Information reconciling forward-looking EBITDA or Adjusted EBITDA to forward-looking consolidated net income (loss) would require a forward-looking statement of consolidated net income (loss) prepared in accordance with GAAP, which is unavailable to us without unreasonable effort. We are not able to provide a quantitative reconciliation of forward-looking EBITDA or Adjusted EBITDA to forward-looking consolidated net income (loss) because certain items required for reconciliation are uncertain, outside of our control and/or cannot reasonably be predicted, such as net sales, cost of goods sold, unrealized derivative gains and losses, asset impairments and provision (benefit) for income taxes, which we view as the most material components of consolidated net income (loss) that are not presently estimable.

Reconciliation of Adjusted EBITDA to Consolidated Net Loss

2024 Financial Performance Summary

Our consolidated net sales declined by $0.3 billion to $1.0 billion for 2024 from $1.2 billion for 2023. Our net loss attributable to common stockholders increased by $31.0 million to a net loss of $60.3 million for 2024 from a net loss of $29.3 million for 2023.

Factors that contributed to these results of operations for 2024 include:

Sales and Margins

We generate sales by marketing all of the alcohols produced by our three production facilities in Illinois, all of the fuel-grade ethanol produced by our production facilities in Oregon and Idaho, and fuel-grade ethanol purchased from third-party suppliers throughout the United States. We also market essential ingredients produced by our production facilities, including dried yeast, corn protein meal, corn protein feed, corn germ, and distillers grains and liquid feed used in commercial animal feed and pet foods. We also sell yeast and liquid CO₂ for human consumption.

Our profitability is highly dependent on various commodity prices, including the market prices of corn, natural gas and fuel-grade ethanol.

Our consolidated average alcohol sales price declined by 21% to $1.95 per gallon for 2024 compared to $2.47 per gallon for 2023. The average price of fuel-grade ethanol as reported by the Chicago Mercantile Exchange, or CME, declined by 24% to $1.69 per gallon for 2024 compared to $2.22 per gallon for 2023. Our average cost of corn declined by 28% to $4.72 per bushel for 2024 from $6.58 per bushel for 2023. The average price of corn as reported by the CME declined by 25% to $4.24 per bushel for 2024 from $5.64 per bushel for 2023.

We believe that our gross profit margins depend primarily on the following key factors:

We seek to optimize our gross profit margins by anticipating the factors above and, when resources are available, implementing hedging transactions and taking other actions designed to lock in margins, limit risk and otherwise address these factors. For example, we may seek to reduce inventory levels in anticipation of declining alcohol or essential ingredient prices and increase production and inventory levels in anticipation of rising alcohol or essential ingredient prices. We may also seek to alter our proportion or timing, or both, of purchase and sales commitments.

Our inability to anticipate the factors described above or their relative importance, and adverse movements in the factors themselves, could result in declining or even negative gross profit margins over certain periods of time. Our ability to anticipate these factors or favorable movements in these factors may enable us to generate above-average gross profit margins. However, given the difficulty associated with successfully forecasting any of these factors, we are unable to estimate our future sales or gross profit margins.

Certain performance metrics that we believe are important indicators of our results of operations include the following:

Year Ended December 31, 2024 Compared to the Year Ended December 31, 2023

Net Sales

The decline in our consolidated net sales for 2024 as compared to 2023 was due to a decrease in our average sales price per gallon for our alcohols and lower volumes of essential ingredients sold at lower prices, partially offset by a higher volume of alcohol sold. Our average sales price per gallon declined primarily due to lower fuel-grade ethanol prices largely driven by lower oil and gasoline prices in 2024 compared to the prior year.

We also produced and sold fewer tons of essential ingredients primarily due to lower alcohol production in 2024 compared to 2023. Our average sales price for our essential ingredients declined primarily due to lower corn prices.

Partially offsetting these declines, we sold more total gallons for 2024 as compared to 2023 resulting primarily from an increase in our specialty alcohol gallons sold and third-party gallons sold, partially offset by lower renewable fuel production gallons sold due to downtime at both our Magic Valley facility and our Pekin Campus, as discussed above. We were able to produce and sell more specialty alcohol due in part to higher production from our Pekin Campus wet mill after our biennial maintenance outage during the year.

Pekin Campus Production Segment

Net sales of alcohol from our Pekin Campus production segment declined by $86.5 million, or 17%, to $415.7 million for 2024 as compared to $502.2 million for 2023. Our total volume of production gallons sold, however, increased by 4.7 million gallons, or 2%, to 213.6 million gallons for 2024 as compared to 208.9 million gallons for 2023, due to production benefits realized in second half of the year from our biennial maintenance performed in Spring 2024 resulting in higher production rates.

At the segment’s average sales price per gallon of $1.95 for 2024, we generated $9.1 million in additional net sales from the 4.7 million additional gallons of alcohol sold in 2024 as compared to 2023. However, a decrease of $0.45, or 19%, in the segment’s average sales price per gallon in 2024 as compared to 2023 resulted in a $95.6 million decline in net sales as compared to 2023.

Net sales of essential ingredients declined by $48.4 million, or 22%, to $169.3 million for 2024 as compared to $217.7 million for 2023. Our total volume of essential ingredients sold increased by 27,900 tons, or 3%, to 906,300 tons for 2024 from 878,400 tons for 2023. Sales volumes of essential ingredients from our Pekin Campus were higher in 2024 due to higher production rates for the year. At our average sales price per ton of $186.81 for 2024, we generated $5.2 million in additional net sales from the 27,900 additional tons of essential ingredients sold in 2024 as compared to 2023. A decrease of $61.03, or 25%, in our average sales price per ton in 2024 as compared to 2023 resulted in a $53.6 million decline in net sales as compared to 2023.

Marketing and Distribution Segment

Net sales of renewable fuel from our marketing and distribution segment, excluding intersegment sales, decreased by $46.5 million, or 18%, to $216.5 million for 2024 as compared to $263.0 million for 2023.

Our volume of third-party renewable fuel sold reported gross by the segment increased by 5.7 million gallons, or 6%, to 108.3 million gallons for 2024 as compared to 102.6 million gallons for 2023. This increase resulted from a shift in the source of renewable fuel from our Magic Valley facility to third-party suppliers. At the segment’s average sales price per gallon of $2.00 for 2024, net sales were $11.4 million higher as a result of the 5.7 million additional gallons sold in 2024 as compared to 2023. This increase was partially offset by the $0.56 decrease in our average sales price per gallon for 2024. The decrease of $0.56, or 22%, in our average sales price per gallon in 2024 as compared to 2023 resulted in a $57.9 million decline in net sales from our third-party renewable fuel sold by the segment compared to 2023.

Western Production Segment

Net sales of alcohol from our Western production segment declined by $51.6 million, or 31%, to $115.4 million for 2024 as compared to $167.0 million for 2023. Our total volume of gallons sold declined by 6.5 million gallons, or 10%, to 60.5 million gallons for 2024 as compared to 67.0 million gallons for 2023. This decline in sales volume primarily resulted from lower production from our Magic Valley facility. At the segment’s average sales price of $1.91 per gallon for 2024, net sales were $12.4 million lower as a result of the 6.5 million fewer gallons sold in 2024 as compared to 2023. A decline of $0.58, or 23%, in our average sales price per gallon in 2024 as compared to 2023 resulted in a $39.2 million decrease in net sales of alcohol from the segment compared to 2023.

Net sales of essential ingredients declined by $20.3 million, or 35%, to $37.0 million for 2024 as compared to $57.3 million for 2023. Our total volume of essential ingredients sold declined by 127,700 tons, or 20%, to 514,600 tons for 2024 from 642,300 tons for 2023. At our average sales price of $71.81 per ton for 2024, net sales were $9.2 million lower as a result of the 127,700 fewer tons sold in 2024 as compared to 2023. In addition, our sales price declined by $17.35 per ton for 2024. The decline of $17.35, or 19%, in our average sales price per ton in 2024 as compared to 2023 resulted in a decrease of $11.1 million in net sales of essential ingredients from the segment compared to 2023.

Corporate and Other Segment

Net sales from our Corporate and other segment declined by $4.4 million or 28% to $11.4 million for 2024 as compared to $15.8 million for 2023. These results are from Eagle Alcohol’s business.

Cost of Goods Sold and Gross Profit

Our consolidated gross profit declined to a gross profit of $9.7 million, representing a gross margin of 1.0% for 2024, from $15.7 million, representing a gross margin of 1.3%, for 2023. Our consolidated gross profit declined due to lower overall commodity crush margins, particularly for renewable fuel, primarily due to lower sales prices as well as lower margins on essential ingredients sold due to lower corn prices. We spent a total of $34.6 million for repairs and maintenance, in-line with our 2024 estimate.

Pekin Campus Production Segment

Our Pekin Campus production segment’s gross profit improved by $12.7 million to a gross profit of $25.9 million from $13.3 million. Of this increase, $12.1 million is attributable to higher commodity crush margins and $0.6 million is attributable to increased sales volumes in 2024 as compared to 2023.

Marketing and Distribution Segment

Our marketing and distribution segment’s gross profit declined by $0.2 million to a gross profit of $4.0 million for 2024 from $4.2 million for 2023. Of this decrease, $0.4 million is attributable to lower margins from sales of third-party renewable fuel, partially offset by an increase of $0.2 million attributable to higher marketing volumes of third-party renewable fuel sold reported gross in 2024 as compared to 2023.

Western Production Segment

Our Western production segment’s gross loss worsened by $13.8 million to a gross loss of $19.3 million for 2024 as compared to a gross loss of $5.5 million for 2023. Of this decline, $15.8 million is attributable to significantly lower margins for renewable fuel, partially offset by $2.0 million attributable to lower sales volumes at negative margins in 2024 as compared to 2023.

Corporate and Other Segment

Gross profit and loss from our Corporate and other segment was a gross loss of $0.9 million for 2024 and a gross profit of $3.7 million for 2023, primarily from Eagle Alcohol’s business.

Selling, General and Administrative Expenses

Our selling, general and administrative, or SG&A, expenses decreased by $0.1 million to $29.7 million for 2024 as compared to $29.8 million for 2023. SG&A expenses decreased primarily due to lower professional fees.

Acquisition-related Expenses

Our acquisition-related expenses increased by $4.9 million to $7.7 million for 2024 as compared to $2.8 million for 2023. These expenses relate to the acceleration of stock payments to the former owners of Eagle Alcohol.

Asset Impairments

We recorded asset impairment charges of $24.8 million for 2024 as compared $6.5 million for 2023. The 2024 impairments reflect $21.4 million for our Magic Valley asset group, as we cold-idled the plant at the end of the year, and $3.4 million for intangible assets of Eagle Alcohol. The 2023 impairments relate to the goodwill associated with our acquisition of Eagle Alcohol.

Interest Expense, net

Interest expense, net, increased by $0.2 million to $7.6 million for 2024 from $7.4 million for 2023. The increase in interest expense, net, is primarily due to higher debt balances, as well as higher interest rates under Kinergy’s line of credit.

Year Ended December 31, 2023, Compared to the Year Ended December 31, 2022

An analysis of our financial results comparing 2023 to 2022 can be found under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the Securities and Exchange Commission on March 14, 2024, which is available free of charge on the Securities and Exchange Commission’s website at www.sec.gov.

Liquidity and Capital Resources

During the year ended December 31, 2024, we funded our operations primarily from cash on hand and proceeds from Kinergy’s operating line of credit. In addition to funding our operations, we used our capital resources to continue our capital improvement projects, make an annual cash payment related to our acquisition of Eagle Alcohol and pay preferred stock dividends.

As of December 31, 2024, we had $35.5 million in cash and cash equivalents and $23.1 million available for borrowing under Kinergy’s operating line of credit. In addition, we have up to an additional $65.0 million that may be available for capital improvement projects under our Orion term loan discussed below, subject to certain conditions. We believe we have sufficient sources of liquidity to meet our anticipated working capital, debt service, capital expenditure and other liquidity needs for at least the next twelve months from the date of this report.

Quantitative Year-End Liquidity Status

We believe that the following amounts provide insight into our liquidity and capital resources. The following selected financial information should be read in conjunction with our consolidated financial statements and notes to consolidated financial statements included elsewhere in this report, and the other sections of “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in this report (dollars in thousands).

Restricted Net Assets

At December 31, 2024, we had approximately $54.1 million of net assets at our subsidiaries that were not available to be transferred to Alto Ingredients, Inc. in the form of dividends, distributions, loans or advances due to restrictions contained in our subsidiaries’ credit facilities.

Changes in Working Capital and Cash Flows

Working capital declined to $95.3 million at December 31, 2024 from $103.5 million at December 31, 2023 as a result of a $15.7 million decrease in current assets, partially offset by a $7.5 million decrease in current liabilities.

Current assets declined primarily due to decreases in restricted cash, inventories and other current assets. Our current liabilities declined primarily due to decreases in derivative instruments and accrued liabilities.

Our cash, cash equivalents and restricted cash declined by $9.3 million due to $3.5 million of cash used in our operating activities and $13.5 million of cash used in our investing activities primarily for our capital improvement projects, partially offset by $7.7 million in cash provided by our financing activities, primarily due to proceeds from our operating line of credit.

Cash used in our Operating Activities

We used $3.5 million in cash in our operating activities during 2024, as compared to $22.0 million in cash generated from our operating activities in 2023. Specific factors that contributed significantly to the change in cash generated by our operating activities include:

These amounts were partially offset by:

Cash used in our Investing Activities

We used $13.5 million of cash in our investing activities for 2024, of which $11.1 million was for additions to property and equipment resulting from our capital improvement projects and $2.8 million is attributable to cash paid for our acquisition of Eagle Alcohol.

Cash provided by our Financing Activities

Cash provided by our financing activities was $7.7 million for 2024, of which $9.0 million is attributable to net proceeds from Kinergy’s line of credit, partially offset by $1.3 million of preferred stock dividends.

Kinergy’s Operating Line of Credit

Kinergy maintains an operating line of credit for an aggregate amount of up to $100.0 million. The credit facility matures on November 7, 2027. Interest accrues under the credit facility at a rate equal to (i) the daily Secured Overnight Financing Rate, plus (ii) a specified applicable margin ranging from 1.25% to 1.75%. The credit facility’s monthly unused line fee is 0.25% to 0.375% of the amount by which the maximum credit under the facility exceeds the average daily principal balance during the immediately preceding month. Payments that may be made by Kinergy to Alto Ingredients, Inc. as reimbursement for management and other services provided by Alto Ingredients, Inc. to Kinergy are limited under the terms of the credit facility to $1.5 million per fiscal quarter. The credit facility also includes the accounts receivable of our indirect wholly-owned subsidiary, Alto Nutrients, LLC, or Alto Nutrients, as additional collateral. Payments that may be made by Alto Nutrients to Alto Ingredients, Inc. as reimbursement for management and other services provided by Alto Ingredients, Inc. to Alto Nutrients are limited under the terms of the credit facility to $0.5 million per fiscal quarter. Alto Nutrients markets our essential ingredients and also provides raw material procurement services to our subsidiaries. In addition, the amount of cash distributions that Kinergy or Alto Nutrients may make to us is also limited to up to 75% of excess cash flow.

For all monthly periods in which excess borrowing availability falls below a specified level, Kinergy and Alto Nutrients must collectively maintain a fixed-charge coverage ratio (calculated as a twelve-month rolling earnings before interest, taxes, depreciation and amortization divided by the sum of interest expense, capital expenditures, principal payments of indebtedness, indebtedness from capital leases and taxes paid during such twelve-month rolling period) of at least 1.1 and are prohibited from incurring certain additional indebtedness (other than specific intercompany indebtedness). The obligations of Kinergy and Alto Nutrients under the credit facility are secured by all of our tangible and intangible assets.

We believe Kinergy and Alto Nutrients are in compliance with the fixed-charge coverage ratio covenant as of the filing of this report. The following table sets forth the fixed-charge coverage ratio financial covenant and the actual results for the periods presented:

Alto Ingredients, Inc. has guaranteed all of Kinergy’s obligations under the credit facility. As of December 31, 2024, Kinergy had an outstanding balance of $39.7 million and $23.1 million of unused borrowing availability under the credit facility.

Orion Term Loan

On November 7, 2022, we entered into a credit agreement with certain funds managed by Orion Infrastructure Capital, or Lenders, under which the Lenders extended a senior secured credit facility in the amount of up to $125.0 million, or Term Loan. The Term Loan is secured by a first priority lien on certain of our assets and a second priority lien on certain assets of Kinergy and Alto Nutrients. Interest accrues on the unpaid principal amount of the Term Loan at a fixed rate of 10% per annum. The Term Loan matures on November 7, 2028, or earlier upon acceleration.

We must prepay amounts outstanding under the Term Loan on a semi-annual basis beginning with the six-month period ending December 31, 2023 in an amount equal to a percentage of our excess cash flow based on a specified leverage ratio, as follows: (i) if our leverage ratio is greater than or equal to 3.0x, then the mandatory prepayment amount will equal 100% of our excess cash flow, (ii) if our leverage ratio is less than 3.0x and greater than or equal to 1.5x, then the mandatory prepayment amount will equal 50% of our excess cash flow, and (iii) if our leverage ratio is less than 1.5x, then the mandatory prepayment amount will equal 25% of our excess cash flow.

As of December 31, 2024 and 2023, the principal amount outstanding under the Term Loan was $60.0 million.

Other Cash Obligations

As of December 31, 2024, we had future commitments for certain capital projects totaling $9.1 million. These commitments are scheduled to be satisfied through 2025.

In connection with our acquisition of Eagle Alcohol, we are committed to pay contingent payments of up to $2.7 million in the first half of 2025.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments 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 amount of net sales and expenses for each period. The following represents a summary of our critical accounting policies and related estimates, defined as those policies that we believe are the most important to the portrayal of our financial condition and results of operations and that require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effects of matters that are inherently uncertain.

Accounting for Business Combinations

Determining the fair value of assets acquired and liabilities assumed in a business combination is considered a critical accounting estimate because the allocation of the purchase price to assets acquired and liabilities assumed based upon fair values requires significant management judgment and the use of subjective measurements. Variability in industry conditions and changes in assumptions or subjective measurements used to allocate fair value are reasonably possible and may have a material impact on our financial position, liquidity or results of operations.

Revenue Recognition

We recognize revenue primarily from sales of alcohols and essential ingredients.

We have five alcohol production facilities from which we produce and sell alcohols to our customers through our subsidiary, Kinergy. Kinergy enters into sales contracts with customers under exclusive intercompany sales agreements with each of our five production facilities. Kinergy also acts as a principal when it purchases third party fuel-grade ethanol which it resells to its customers. Finally, in 2022, Kinergy had exclusive sales agreements with two third-party owned fuel-grade ethanol plants under which it sold the plants’ fuel-grade ethanol production for a fee plus the costs to deliver the ethanol to Kinergy’s customers. Kinergy has since terminated these contracts. These sales are referred to as third-party agent sales. Revenue from these third-party agent sales is recorded on a net basis, with Kinergy recognizing its predetermined fees and any associated delivery costs.

We have five production facilities from which we produce and sell essential ingredients to our customers through our subsidiary, Alto Nutrients. Alto Nutrients enters into sales contracts with essential ingredient customers under exclusive intercompany sales agreements with each of our five production facilities.

We recognize revenue from sales of alcohols and essential ingredients at the point in time when the customer obtains control of the products, which typically occurs upon delivery depending on the terms of the underlying contracts. In some instances, we enter into contracts with customers that contain multiple performance obligations to deliver volumes of alcohols or essential ingredients over a contractual period of less than 12 months. We allocate the transaction price to each performance obligation identified in the contract based on relative standalone selling prices and recognize the related revenue as control of each individual product is transferred to the customer in satisfaction of the corresponding performance obligations.

When we are the agent, the supplier controls the products before they are transferred to the customer because the supplier is primarily responsible for fulfilling the promise to provide the product, has inventory risk before the product has been transferred to a customer and has discretion in establishing the price for the product. When we are the principal, we control the products before they are transferred to the customer because we are primarily responsible for fulfilling the promise to provide the products, we have inventory risk before the product has been transferred to a customer and we have discretion in establishing the price for the product.

See “Note 4 – Segments” of the Notes to Consolidated Financial Statements for our revenue breakdown by type of contract.

Impairment of Long-Lived Assets

Our long-lived assets have been primarily associated with our production facilities, reflecting their original cost, adjusted for depreciation and amortization and any subsequent impairment.

We assess the impairment of long-lived assets, including property and equipment, when events or changes in circumstances indicate that the fair value of an asset group could be less than the net book value of the asset group. Generally, we assess long-lived assets for impairment by first determining the forecasted, undiscounted cash flows each asset is expected to generate plus the net proceeds expected from the sale of the asset group. If the total amount of the undiscounted cash flows is less than the carrying value of the asset group, we then determine the fair value of the asset group. When the estimated fair value of the asset group is less than its carrying value, we recognize an impairment expense equal to the difference between the asset group’s carrying value and estimated fair value. Forecasts of future cash flows are estimates based on our experience and knowledge of our operations and the industry in which we operate. These estimates could be significantly affected by future changes in market conditions, the economic environment, including inflation, and the purchasing decisions of our customers. As a result, we recorded asset impairments of $21.4 million and $0.6 million with respect to our Magic Valley facility and right of use assets associated with our operating leases for the years ended December 31, 2024 and 2023, respectively.

We review our intangible assets, including goodwill, with indefinite lives at least annually or more frequently if impairment indicators arise. In our review, we determine the fair value of these assets using market multiples and discounted cash flow modeling and compare it to the net book value of the reporting unit. Any assessed impairments will be recorded permanently and expensed in the period in which the impairment is determined. We performed our annual review of impairment and recognized asset impairments of $3.4 million and $6.0 million against our intangible assets and goodwill for the years ended December 31, 2024 and 2023, respectively. We did not recognize any asset impairments for the year ended December 31, 2022.

Valuation Allowance for Deferred Taxes

We account for income taxes under the asset and liability approach, where deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities, and are measured using enacted tax rates and laws that are expected to be in effect when the differences reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.

We evaluate our deferred tax asset balance for realizability. To the extent we believe it is more likely than not that some portion or all of our deferred tax assets will not be realized, we will establish a valuation allowance against the deferred tax assets. Realization of our deferred tax assets is dependent upon future taxable income during the periods in which the associated temporary differences become deductible. We consider the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. These changes, if any, may require possible material adjustments to these deferred tax assets, resulting in a reduction in net income or an increase in net loss in the period when such determinations are made.

We had pre-tax consolidated net losses of $58.8 million, $27.9 million and $39.7 million for the years ended December 31, 2024, 2023 and 2022, respectively. Based on our current and prior results, we do not have sufficient evidence to support a conclusion that we will more likely than not be able to benefit from our remaining deferred tax assets. As such, we have recorded a valuation allowance against our net deferred tax assets.

Derivative Instruments

We evaluate our contracts to determine whether the contracts are derivative instruments. Management may elect to exempt certain forward contracts that meet the definition of a derivative from derivative accounting as normal purchases or normal sales. Normal purchases and normal sales are contracts that provide for the purchase or sale of something other than a financial instrument or derivative instrument that will be delivered in quantities expected to be used or sold over a reasonable period in the normal course of business. Contracts that meet the requirements of normal purchases or sales are documented as normal and exempted from the fair value accounting and reporting requirements of derivative accounting.

We enter into short-term cash, option and futures contracts as a means of securing purchases of corn, natural gas and sales of fuel-grade ethanol and managing exposure to changes in commodity prices. All of our exchange-traded derivatives are designated as non-hedge derivatives for accounting purposes, with changes in fair value recognized in net income. Although the contracts are economic hedges of specified risks, they are not designated or accounted for as hedging instruments.

Realized and unrealized gains and losses related to exchange-traded derivative contracts are included as a component of cost of goods sold in the accompanying financial statements. The fair values of contracts entered through commodity exchanges are presented on the accompanying balance sheet as derivative assets or liabilities. The selection of normal purchase or sales contracts, and use of hedge accounting, are accounting policies that can change the timing of recognition of gains and losses in the statement of operations.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to various market risks, including changes in commodity prices, as discussed below. Market risk is the potential loss arising from adverse changes in market rates and prices. In the ordinary course of business, we may enter into various types of transactions involving financial instruments to manage and reduce the impact of changes in commodity prices. We do not have material exposure to interest rate risk. We do not expect to have any exposure to foreign currency risk as we conduct all of our transactions in U.S. dollars.

We produce and distribute specialty alcohol, fuel-grade ethanol and essential ingredients. Our business is sensitive to changes in the prices of ethanol and corn. In the ordinary course of business, we may enter into various types of transactions involving financial instruments to manage and reduce the impact of changes in ethanol and corn prices. We do not enter into derivatives or other financial instruments for trading or speculative purposes.

We are subject to market risk with respect to ethanol and corn pricing. Ethanol prices are sensitive to global and domestic ethanol supply; crude-oil supply and demand; crude-oil refining capacity; carbon intensity; government regulation; and consumer demand for alternative fuels. Our ethanol sales are priced using contracts that are either based on a fixed price or an indexed price tied to a specific market, such as Chicago Ethanol (Platts) or the Oil Price Information Service. Under these fixed-priced arrangements, we are exposed to risk of a decrease in the market price of ethanol between the time the price is fixed and the time the alcohol is sold.

We satisfy our physical corn needs, the principal raw material used to produce alcohol and essential ingredients, based on purchases from our corn vendors. Generally, we determine the purchase price of our corn at or near the time we begin to grind. Additionally, we also enter into volume contracts with our vendors to fix the purchase price. As such, we are also subject to market risk with respect to the price of corn. The price of corn is subject to wide fluctuations due to unpredictable factors such as weather conditions, farmer planting decisions, governmental policies with respect to agriculture and international trade and global supply and demand. Under the fixed price arrangements, we assume the risk of a decrease in the market price of corn between the time the price is fixed and the time the corn is utilized.

Essential ingredients are sensitive to various demand factors such as numbers of livestock on feed, prices for feed alternatives and supply factors, primarily production of ethanol co-products by ethanol plants and other sources.

As noted above, we may attempt to reduce the market risk associated with fluctuations in the price of ethanol or corn by employing a variety of risk management and hedging strategies. Strategies include the use of derivative financial instruments such as futures and options executed on the CME and/or the New York Mercantile Exchange, as well as the daily management of physical corn.

These derivatives are not designated for special hedge accounting treatment, and as such, the changes in the fair values of these contracts are recorded on the balance sheet and recognized immediately in cost of goods sold. We recognized net gains of $11.0 million, net losses of $8.0 million and net gains of $19.3 million related to the change in the fair values of these contracts for the years ended December 31, 2024, 2023 and 2022, respectively.

We prepared a sensitivity analysis as of December 31, 2024 to estimate our exposure to ethanol and corn. Market risk related to these factors was estimated as the potential change in pre-tax income resulting from a hypothetical 10% adverse change in the prices of our expected ethanol and corn volumes. The analysis uses average CME prices for the year and does not factor in future contracted volumes. The results of this analysis for the year ended December 31, 2024, which may differ materially from actual results, are as follows (in millions):

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

We conducted an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. The term “disclosure controls and procedures,” as defined in Rules 13a-15I and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures also include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded as of December 31, 2024 that our disclosure controls and procedures were effective at a reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that:

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

A material weakness is defined by the Public Company Accounting Oversight Board’s Audit Standards AS 2201 as being a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis by the company’s internal controls.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework set forth in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework set forth in Internal Control — Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective as of December 31, 2024.

RSM US LLP, an independent registered public accounting firm, has issued an attestation report on our internal control over financial reporting as of December 31, 2024. That report is included in Part IV of this report.

Inherent Limitations on the Effectiveness of Controls

Management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control systems are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in a cost-effective control system, no evaluation of internal control over financial reporting can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been or will be detected.

These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of a simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information.

During the three months ended December 31, 2024, none of our directors or officers (as defined in Rule 16a-1(f) of the Securities Exchange Act of 1934, as amended) informed us of the adoption, modification or termination of a Rule 10b5-1 trading arrangement or non-Rule 10b5-1 trading arrangement (as such terms are defined in Item 408 of Regulation S-K of the Securities Act of 1933, as amended).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Alto Ingredients, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Alto Ingredients, Inc. and its subsidiaries (the Company) as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2024, and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated March 13, 2025, expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Long-lived asset impairment

As described in Note 1 to the financial statements, the Company assesses the impairment of long-lived assets when events or changes in circumstances indicate that the fair value of assets could be less than their carrying value. In such event, the Company assesses long-lived assets for impairment by first determining the forecasted, undiscounted cash flows the asset group is expected to generate plus the net proceeds expected from the sale of the asset group. If this amount is less than the carrying value of the asset group, the Company will then determine the fair value of the asset group. When the estimated fair value of the asset group is less than its carrying value, the Company recognizes an impairment expense equal to the difference between the asset group’s carrying value and estimated fair value. The Company’s assessment resulted in an asset impairment of $24,790,000 for the year ended December 31, 2024.

We identified the evaluation of the fair value of asset groups, where fair value was required to be determined as part of the impairment analysis, as a critical audit matter because of the significant estimates management makes when determining fair value. This required a high degree of auditor judgment when performing audit procedures to evaluate whether management appropriately determined fair value.

Our audit procedures related to the evaluation of fair value, where fair value was required to be determined as part of the impairment analysis, included the following, among others:

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Alto Ingredients, Inc.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
