Hawkeye Holdings Inc. was formed as a Delaware corporation in May 2006, and has not commenced operations and has no significant assets or liabilities. Our business has been conducted through limited liability companies. Hawkeye Holdings, L.L.C.—formerly known as Iowa Falls Ethanol Plant, L.L.C.—was organized in Iowa on October 22, 2003. On February 22, 2005, Hawkeye Holdings, L.L.C. formed a wholly-owned subsidiary, Hawkeye Renewables, LLC, a Delaware limited liability company, to which it transferred substantially all of its assets and liabilities.

Prior to the effective date of this offering, we will implement a new holding company structure, in which Hawkeye Renewables, LLC will become our indirect wholly-owned limited liability company subsidiary, and Hawkeye Holdings, L.L.C., our current parent entity, and THL will exchange their interests in our business for common and preferred stock of Hawkeye Holdings Inc.

Business Overview

We are the third largest ethanol producer in the United States based on production capacity. We believe that our access to low-cost corn supplies, approach to marketing our ethanol, operating scale, transportation infrastructure and operational expertise allow us to be one of the lowest-cost producers of ethanol in the United States. We own two of the largest ethanol production facilities in the United States and we are capable of producing aggregate ethanol output of approximately 205 MMGPY. Our Iowa Falls plant began operations in November 2004 and expanded to its current production capacity of 100 MMGPY in March 2006. In May 2006, our Fairbank plant began operations with 105 MMGPY of production capacity. In addition to producing ethanol, we produce and sell distillers grains as ethanol co-products, which serve to offset a portion of our corn costs. We intend to expand our production capacity by another 200 MMGPY over the next few years, by breaking ground on our third plant in 2006 and our fourth plant in 2007, which will bring our total production capacity to over 400 MMGPY. We anticipate that the time from groundbreaking to start-up of production for each of these plants will be approximately 18 months.

The table below provides an overview of our ethanol plants that are in operation as of May 2006.

	Iowa Falls plant	Fairbank plant
Location	Iowa Falls, Iowa	Fairbank, Iowa
Date of completion	November 2004 (expansion March 2006)	May 2006
Annual ethanol production capacity (in millions of gallons)	100	105
Ownership	100%	100%
Production process	Dry-Milling	Dry-Milling
Primary energy source	Natural Gas	Natural Gas
Estimated distillers grains production (dry equivalents) per year	315,000 tons	330,000 tons
Estimated corn processed per year	35 million bushels	37 million bushels
Corn grown during 2004-2005 crop year within a 60-mile radius	546 million bushels	447 million bushels

For the year ended December 31, 2005, we generated revenue of $89.1 million, net income of $8.6 million and EBITDA of $26.1 million, and we sold 48.3 million gallons of ethanol at an average price per gallon of $1.65. For the three months ended March 31, 2006, we generated revenue of $27.8 million, net income of $6.8 million and EBITDA of $9.6 million, and we sold 13.6 million gallons of ethanol at an average price per gallon of $1.83. We have sold forward 32% of our estimated ethanol production for the 12-month period ending June 30, 2007 at an average price of $2.01 per gallon. For a reconciliation of net income to EBITDA, see footnote 4 under "—Summary Historical and Pro Forma Consolidated Financial Data."

Industry Overview

Ethanol is a clean-burning, high-octane fuel that is produced from renewable sources. In the United States, ethanol is produced primarily from corn and is used as a vehicle fuel and as a gasoline fuel additive to increase gasoline's octane rating and to comply with air emissions regulations by reducing emissions of carbon monoxide and nitrogen oxides. Ethanol currently comprises 3% of the total U.S. gasoline fuel supply, and is blended into one-third of the gasoline consumed in the United States. All automobiles in the United States can operate within warranty using a fuel mix that is 90% gasoline and 10% ethanol, also referred to as E10 fuel. Ethanol comprises up to 85% of E85 fuel. Although E85 fuel currently represents a small portion of the U.S. gasoline supply, approximately six million vehicles in the U.S. today are Flexible Fuel Vehicles—FFVs—capable of using E85 fuel.

The ethanol industry has grown significantly over the last few years, expanding production capacity at a compound annual growth rate of approximately 20% from 2000 to 2005, according to the Renewable Fuels Association—the RFA. We believe the ethanol market will continue to grow as a result of ethanol's favorable production economics relative to gasoline, a shortage of domestic petroleum refining capacity, federally-mandated renewable fuel usage, favorable tax treatment, ethanol's clean burning characteristics and geopolitical and environmental concerns with petroleum-based fuels.

Drivers of substantial growth prospects in the ethanol market include:

Favorable production economics. We believe that the costs ethanol producers incur in producing a gallon of ethanol currently are significantly lower than the costs refiners incur in producing a gallon of petroleum-based gasoline.

Favorable tax treatment. Ethanol's favorable production economics are further enhanced as a result of a federal tax credit amounting to $0.51 per gallon—$.051 per gallon of gasoline at a 10% blend—that is received by refiners for blending ethanol into their fuels, which can be captured by

the refiner or passed on to the consumer. We believe ethanol's favorable production economics, further enhanced by the blenders' tax credit, will enable ethanol to comprise an increasingly larger portion of the U.S. fuel supply.

Inadequate supply to meet demand. We believe that the ethanol industry lacks sufficient capacity to meet current and anticipated demand. With the withdrawal of MTBE from the nation's gasoline supply, we believe that the demand for oxygenates, including ethanol, will exceed six billion gallons in the next few years.

Blending benefits. Ethanol has an octane rating of 113 and is added to the blend stock to raise the octane level from gasoline's base level of approximately 84 to the typical octane ranges sold by the gasoline retailers today of 87 to 93 octane—regular unleaded to super high-octane. Fuel sources with higher octane typically have been sold at a higher price per gallon relative to lower-octane fuel sources due to the benefits associated with a higher octane content.

Expansion of gasoline supply. By blending ethanol into their gasoline, refiners can expand the volume of fuel available to be sold and therefore can produce more fuel from a barrel of oil and expand their ability to meet consumer demand, especially during times when refinery capacity and octane sources are limited.

Renewable Fuels Standard. In August 2005, President Bush signed the Energy Policy Act, which established the Renewable Fuels Standard—RFS. The RFS mandates minimum annual use of 7.5 billion gallons per year of renewable fuels in the U.S. fuel supply by 2012. We believe that the RFS will increase demand for ethanol.

Environmental benefits. Ethanol, as an oxygenate, reduces tailpipe emissions when added to gasoline, resulting in improved air quality. The additional oxygen in the ethanol results in a more complete combustion of the fuel in the engine cylinder, resulting in reduced carbon monoxide and nitrogen oxides emissions.

Competitive Strengths

We believe that we have the following competitive strengths:

State-of-the-art production technology and operational scale. We have approximately 205 million gallons of annual production capacity at our two state-of-the-art plants, which were designed by ICM, Inc., and built by Fagen, Inc. As a result of the ICM process technology, our plants have one of the highest corn-to-ethanol conversion yields in the ethanol industry today. In addition, we believe our plants have higher throughput, lower production costs and higher operating efficiency than smaller and older plants, which make up the vast majority of industry capacity. The average size of an ethanol production facility in the U.S. is approximately 46 MMGPY, according to the RFA. In addition, we believe that our plants operate at among the lowest ratios of plant-level employees per gallon of annual production capacity in our industry.

Optimal locations for low-cost corn supply. The location of our plants in Iowa, in some of the highest yielding areas of the nation's "Corn Belt," gives us ready access to corn at favorable prices. We purchase a substantial portion of our corn supply directly from local farmers, which we believe is less costly than purchasing corn from cooperatives or shipping across longer distances. The eight year historical average discount to the Chicago Board of Trade, or CBOT, for corn is $0.32 per bushel in Iowa Falls and $0.26 per bushel in Fairbank.

Advantageous logistics infrastructure and capabilities. Due to the large scale of our facilities, our facilities' access to national rail networks and the ample rail siding at our facilities, we plan to offer to ship entire unit trains—75 or more rail cars at a time—to our ethanol markets, a volume that would allow us to achieve favorable rail rates per gallon with a shorter delivery time. The

relatively rapid delivery time afforded by access to national rail networks also allows us to use leased rail cars more productively, effectively increasing the annual volume each rail car can transport and lowering our per-gallon rail car leasing expense.

Well-positioned to capitalize on industry growth. We have proven our ability to find and secure optimal plant locations and execute on the construction, completion and operation of two of the largest ethanol facilities built in recent years. As the industry expands to satisfy the expected substantial increase in ethanol demand, we are well-positioned with our current expansion plans, which include breaking ground on a new plant in each of 2006 and 2007, to take advantage of this growth.

Experienced management. Our management team has extensive experience in ethanol and a variety of agricultural businesses, and has successfully overseen construction of our Iowa Falls and Fairbank production facilities. We believe our team's long history in the local Iowa markets helps us procure a consistent supply of low-cost corn and foster a source of demand for our distillers grains.

Business Strategy

Our business strategy is to expand production capacity and to maintain our position as a leading low-cost, highly efficient producer of ethanol as the industry grows. We intend to implement our strategy through the following steps:

Maintain focus on cost efficiency and technological advantages. Since our inception, we have striven to operate as a low-cost producer utilizing the latest production technology with access to the lowest cost inputs. As we grow, we will continue to focus on these cost efficiencies and technologies by locating plants in low-cost corn regions and exploring the latest technology to achieve the highest production throughput at the lowest cost.

Expand production capacity through greenfield development. We seek to capitalize on the rapidly growing demand for ethanol by using our project development and operating expertise to add additional production capacity as the industry grows. We have secured the right to acquire four well-located sites in Iowa and we intend to break ground on one plant in 2006 and a second plant in 2007 for an additional 200 MMGPY of production capacity, which will bring our total production capacity to over 400 MMGPY. In addition, we will evaluate opportunities to acquire additional ethanol producers which we can use to leverage our operating expertise.

Capitalize on ethanol marketing advantages. We believe our production scale, our access to national rail networks and destination markets and our plan to offer to ship unit trains provide us with a competitive advantage when marketing our ethanol and result in favorable prices to us. Because of these advantages, we have opted not to be part of a "pooled" marketing program in which those benefits would be shared with other producers in the "pool" that do not enjoy similar competitive advantages.

Employ strategic risk mitigation techniques. We analyze and employ risk mitigation techniques in order to limit our exposure to commodity price fluctuations. These techniques include attempting to match the contracted sales of ethanol with proportionate purchases of corn supply requirements to lock in crush spreads, futures and options positions on the CBOT corn market and forward purchases of natural gas.

Maintain flexibility to optimize production technologies. We review technological developments that might result in more efficient methods of ethanol production. We believe that our facilities will be able to accommodate modifications to utilize different feedstocks or production technologies that may become available in the future.

The THL Transactions and the Conversion

On May 11, 2006, several investment funds affiliated with Thomas H. Lee Partners L.P.—collectively with their co-investors referred to as THL—agreed to acquire an approximate 80% ownership interest in our business in a transaction that valued our business at approximately $1.0 billion. After giving effect to the closing of this transaction, we will have approximately $650.0 million of debt outstanding and $390.0 million of preferred and common equity. We refer to these transactions as the THL Transactions.

Prior to the effective date of this offering, we will implement a new holding company structure, in which Hawkeye Renewables, LLC, which operates our existing business, will become an indirect wholly-owned limited liability company subsidiary of Hawkeye Holdings Inc., the issuer of the shares in this offering. At the same time, Hawkeye Holdings, L.L.C., our current parent entity, and THL will exchange their interests in our business for common and preferred stock of Hawkeye Holdings Inc. We refer to this series of transactions as the "Conversion" and we refer to the THL Transactions, the Conversion and this offering, together with the application of the proceeds from this offering, collectively as the Transactions. We anticipate that $ of the proceeds of this offering will be used to redeem the preferred stock of Hawkeye Holdings Inc.

Unless otherwise stated, all share and per share information contained in this prospectus gives effect to the completion of the THL Transactions and the Conversion, in each case as described under "Certain Relationships and Related Transactions."

Substantially all of the miscellaneous income was derived through a government program established through the United States Department of Agriculture that provided cash payments for companies who generate increases in bioenergy production, such as ethanol, from previous production levels. We do not expect any further income attributable to this program.

EBITDA is defined as net income (loss) before interest expense (net of interest income), income tax expense, depreciation and amortization. Amortization of debt issuance costs and debt discount are included in interest expense. EBITDA is not a measure of financial performance under accounting principles generally accepted in the U.S., or GAAP, and should not be considered an alternative to net income 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 has its limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of the limitations of EBITDA are:

•: EBITDA does not reflect our cash used for capital expenditures;
•: although depreciation and amortization are non-cash charges, the assets being depreciated or amortized often will have to be replaced and EBITDA does not reflect the cash requirements for replacements;
•: EBITDA does not reflect changes in, or cash requirements for, our working capital requirements;
•: EBITDA does not reflect the cash necessary to make payments of interest or principal on our indebtedness; and
•: EBITDA includes non-recurring payments to us which are reflected in other income.

Because of these limitations, EBITDA should not be considered as a measure of discretionary cash available to us to service our debt or to invest in the growth of our business. We compensate for these limitations by relying on our GAAP results as well as on our EBITDA. Management uses EBITDA as a measure of our performance and ability to generate cash necessary to meet our future requirements for debt service, capital expenditures, working capital and taxes. We also believe that EBITDA is useful to investors because it frequently is used by securities analysts, investors and other interested parties to evaluate companies in our industry. Because not all companies use identical calculations, this presentation of EBITDA may not be comparable to other similarly titled measures for other companies. Also, the amounts shown for EBITDA as presented below differ from the amounts calculated under the definition of Adjusted EBITDA used in our debt instruments, which further adjust for certain cash and non-cash charges and are used to determine compliance with financial covenants and our ability to engage in certain activities such as incurring additional debt and making acquisitions.

The following table reconciles our net income (loss) to EBITDA for each period presented. For 2003, the period shown is from October 22, 2003, the date of inception, to December 31, 2003. Prior to the Conversion, we were organized as a limited liability company and were not subject to income taxes.

RISK FACTORS

Investing in our common stock involves a high degree of risk. Before making an investment in our common stock, you should carefully consider the following risks, as well as other information contained in this prospectus, including the consolidated financial statements and related notes and "Management's Discussion and Analysis of Financial Condition and Results of Operations." The risks described below are those that we believe are the material risks we face. Any of the risks described below could significantly and adversely affect our business, prospects, financial condition and results of operations. As a result, the trading price of our common stock could decline and you could lose all or part of your investment.

Risks Relating to Our Business and Industry

Our business is highly dependent on commodity prices, which are subject to significant volatility and uncertainty, and on the availability of raw materials supplies, so our results of operations, financial condition and business outlook may fluctuate substantially.

Our results of operations depend substantially on the prices of various commodities, particularly the prices for ethanol, corn, natural gas and unleaded gasoline. As a result of the volatility of the prices for these items, our results may fluctuate substantially. We may experience periods during which the prices of our products decline and the costs of our raw materials increase, which in turn may result in operating losses and adversely affect our financial condition. We may attempt to offset a portion of the effects of such fluctuations by entering into forward contracts to supply ethanol or to purchase corn, natural gas or other items or by engaging in transactions involving exchange-traded futures contracts, but these activities involve substantial costs, substantial risks and may be ineffective to mitigate these fluctuations. If a substantial imbalance occurred, such as occurred in the first quarter of 2005, we may take actions to mitigate the effect of the imbalance, such as storing our uncontracted ethanol for a period of time, as we did in early 2005. These actions could involve additional costs and could have a negative impact on our operating results.

Our business is highly sensitive to corn prices, and we generally cannot pass on increases in corn prices to our customers.

Corn is the principal raw material we use to produce ethanol and distillers grains. Changes in the price of corn therefore significantly affect our business. In general, rising corn prices produce lower profit margins. Because ethanol competes with fuels that are not corn-based, we generally are unable to pass along increased corn costs to our customers. At certain levels, corn prices would make ethanol uneconomical to use in fuel markets. Corn costs for the year ended December 31, 2005 made up approximately 46.9% of our total operating expenses. The price of corn is influenced by weather conditions and other factors affecting crop yields, farmer planting decisions and general economic, market and regulatory factors, including government policies and subsidies with respect to agriculture and international trade, and global and local supply and demand. Over the ten-year period from 1996 to 2005, corn prices, based on the CBOT daily futures data, have ranged from a low of $1.75 per bushel in 2000 to a high of $5.48 per bushel in 1996, with prices averaging $2.47 per bushel during this period. At March 31, 2006, the CBOT price per bushel of corn was $2.36. Any event that tends to reduce the supply of corn, such as adverse weather or crop disease, could cause the price of corn to increase.

Increased acceptance of ethanol as a fuel could lead to significantly greater demand for corn and increases in the price, and shortages of availability, of corn.

We anticipate that the expansion of the ethanol industry will lead to significantly greater demand for corn. We may have difficulty from time to time in sourcing corn on economical terms, due to supply

shortages. Any supply shortage could require us to suspend operations until corn became available at economical terms. Suspension of operations would have a material adverse effect on our business, results of operations and financial condition. Additionally, the price we pay for corn at any of our production facilities could increase if another ethanol production facility were built in the same general vicinity or if we expand one of our production facilities.

The price spread between ethanol and corn can vary significantly. We do not expect the spread to remain at its recent high levels.

Our gross margin depends principally on the spread—the "crush spread"—between the price of a gallon of ethanol and the price of the amount of corn required to produce a gallon of ethanol. During the five-year period from 2001 to 2005, ethanol prices, based on average U.S. ethanol rack prices reported by Bloomberg, L.P., have ranged from a low of $0.94 per gallon to a high of $2.76 per gallon, averaging $1.50 per gallon during this period. In recent periods, the crush spread between ethanol and corn prices has been at an historically high level, driven in large part by high oil prices and low corn prices. During 2005, however, this spread fluctuated widely. The crush spread may not remain at recent high levels and fluctuations will continue to occur. Any reduction in the crush spread, whether as a result of an increase in corn prices or a reduction in ethanol prices, would adversely affect our results of operations and financial condition.

The market for natural gas is subject to market conditions that create uncertainty in the price and availability of the natural gas that we use in our manufacturing process.

We rely upon third parties for our supply of natural gas, which we use in the ethanol production process. The prices for and availability of natural gas are subject to volatile market conditions. The fluctuations in natural gas prices over the six-year period from December 31, 1999, through December 28, 2005, based on the New York Mercantile Exchange, or NYMEX, daily futures data, have ranged from a low of $1.69 per MMBTU in 2001 to a high of $18.66 per MMBTU in 2003, averaging $5.67 per MMBTU during this period. At May 23, 2006, the NYMEX price of natural gas was $6.27 per MMBTU. These market conditions are often affected by factors beyond our control such as the price of oil as a competitive fuel, higher prices resulting from colder than average weather conditions and overall economic conditions. We currently use approximately 4.0 million MMBTU's of natural gas annually, depending upon business conditions, in the manufacture of our products. Significant disruptions in the supply of natural gas could impair our ability to manufacture ethanol for our customers. Furthermore, increases in natural gas prices could adversely affect our results of operations.

Our profit margins may be adversely affected by fluctuations in the selling price and production cost of gasoline.

Ethanol is marketed both as a fuel additive to reduce vehicle emissions from gasoline and as an octane enhancer to improve the octane rating of the gasoline with which it is blended. As a result, ethanol prices are influenced by the supply of and demand for gasoline. Our results of operations may be materially adversely affected if the demand for or the price of gasoline decreases. Conversely, a prolonged increase in the price of or demand for gasoline could lead the U.S. government to relax import restrictions on foreign ethanol that currently benefit us.

Our results may be adversely affected by hedging transactions and other strategies.

In an attempt to offset some of the effects of volatility of ethanol prices and costs of commodities, we enter into contracts to supply a portion of our ethanol and distillers grains production or purchase a portion of our corn or natural gas requirements on a forward basis. From time to time we also engage in other hedging transactions involving exchange-traded futures contracts for corn and natural gas. The

financial statement impact of these activities depends 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 we have futures contracts. Hedging arrangements also expose us to the risk of financial loss in situations where the other party 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. Hedging activities can themselves result in losses when a position is purchased in a declining market or a position is sold in a rising market. A hedge position is often settled in the same time frame as the physical commodity is either purchased (corn and natural gas) or sold (ethanol). We may experience hedging losses in the future. We also vary the amount of hedging or other price mitigation strategies we undertake, and we may choose not to engage in hedging transactions at all and, as a result, our results of operations and financial condition may be adversely affected by increases in the price of corn or natural gas or decreases in the price of ethanol.

Excess production capacity in our industry resulting from new plants under construction or decreases in the demand for ethanol could adversely affect our business.

According to the RFA, domestic ethanol production capacity has increased from 1.8 billion gallons per year at December 31, 2001 to an estimated 4.5 billion gallons per year in April 2006. The RFA estimates that, as of May 2006, approximately 2.0 billion gallons per year of additional production capacity, an increase of 50% over current production levels, is under construction at 41 new and existing facilities. Excess capacity in the ethanol industry would have an adverse effect on our results of operations, cash flows and financial condition. In a manufacturing industry with excess capacity, producers have an incentive to manufacture additional products for so long as the price exceeds the marginal cost of production (i.e., the cost of producing only the next unit, without regard to interest, overhead or fixed costs). This incentive can result in the reduction of the market price of ethanol to a level that is inadequate to generate sufficient cash flow to cover costs.

Excess ethanol production capacity also may result from decreases in the demand for ethanol, which could result from a number of factors, including regulatory developments and reduced gasoline consumption in the United States. Reduced gasoline consumption could occur as a result of increased prices for gasoline or crude oil, which could cause businesses and consumers to reduce driving or acquire vehicles with more favorable gasoline mileage or as a result of technological advances, such as the commercialization of hydrogen fuel-cells, which could supplant gasoline-powered engines. There are a number of governmental initiatives designed to reduce gasoline consumption, including tax credits for hybrid vehicles and consumer education programs. There is some evidence that reduced gasoline consumption has occurred in the recent past as gasoline prices have increased in the United States.

New, more energy-efficient technologies for producing ethanol could displace corn-based ethanol and materially and adversely affect our results of operations and financial condition.

The development and implementation of new technologies may result in a significant reduction in the costs of ethanol production. We cannot predict when new technologies may become available, the rate of acceptance of new technologies by our competitors or the costs associated with new technologies. Significant amounts of oil and natural gas are required to grow, fertilize and harvest corn, and to ferment and distill corn into ethanol. New technologies that seek to develop more energy-efficient means to produce ethanol from cellulosic biomass could displace the corn-based technologies used in our facilities and materially and adversely affect our business and business prospects. In addition, advances in the development of alternatives to ethanol could significantly reduce demand for or eliminate the need for ethanol. Any advances in technology which require significant capital expenditures to remain competitive or which reduce demand or prices for ethanol could have a material adverse effect on our results of operations and financial condition.

Any disruption in our operations could result in a reduction of sales volume and could cause us to incur substantial losses.

Our revenues are and will continue to be derived from the sale of ethanol and distillers grains that we produce at our facilities. Our operations may be subject to significant interruption if any of our facilities experiences a major accident or is damaged by severe weather or other natural disasters. In addition, our operations may be subject to labor disruptions and unscheduled downtime or other operational hazards inherent in our industry. Some of these operational hazards may 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 be adequate to cover the potential operational hazards described above and we may not be able to renew our insurance on commercially reasonable terms or at all.

We may not be able to implement our expansion strategy.

We may not be able to implement our expansion strategy in the timeframe anticipated or at all. With any proposed facility, we would need to identify a contractor who is experienced building ethanol plants and has the capacity for our project. In addition, we would need to successfully finance, construct, develop and operate new or expanded facilities. There currently are only three contractors with experience building ethanol plants, and only one has previously done large installations, which may make timely completion of our expansion strategy more difficult.

We might not be able to locate suitable sites for construction of new or expanded facilities.

We plan to grow our business by constructing new plants at sites for which we have land options or at other sites. We believe that there is increasing competition for suitable sites, which may increase the cost associated with obtaining a suitable site. While we have options to purchase land in four locations in Iowa, these sites may not be suitable and we might not be able to find suitable additional sites for construction of new facilities or other suitable expansion opportunities.

We might not be able to obtain the necessary financing to implement our expansion strategy.

Even if we find suitable sites or we decide to expand our current facilities, we might not be able to finance these new or expanded facilities. We might not have access to the funding required for the expansion of our business or such funding might not be available to us on acceptable terms. We might finance the expansion of our business with additional indebtedness or by issuing additional equity securities. The amount of any additional indebtedness could be substantial. We could face financial risks associated with incurring additional indebtedness, such as reducing our liquidity and access to financial markets and increasing the amount of cash flow required to service our debt, or associated with issuing additional stock, such as dilution of ownership and earnings. An increase in our debt would decrease the amount of funds available for our growth strategy, thereby making it more challenging to implement our strategy in a timely manner, or at all.

We might not be able to obtain the approvals and permits that will be necessary in order to construct and operate new or expanded facilities as planned.

We must obtain numerous regulatory approvals and permits in order to construct and operate additional or expanded facilities. We might not satisfy these requirements in a timely manner or at all. In addition, as described below under "We may be adversely affected by environmental, health and safety laws, regulations and liabilities," federal and state governmental requirements could substantially increase our costs, which could have a material adverse effect on our results of operations and financial condition. Our expansion plans also may result in other unanticipated adverse consequences, such as the diversion of management's attention from our existing operations.

Our construction costs could increase to levels that would make a new facility too expensive to complete or too unprofitable to operate.

Our construction costs may exceed budgets in material amounts that could adversely affect our financial conditions and our anticipated operating results. We believe that contractors, engineering firms, construction firms and equipment suppliers increasingly are receiving requests and orders from other ethanol companies and, therefore, we may not be able to secure their services or products on a timely basis or on acceptable financial or commercial terms. We may suffer significant delays or cost overruns as a result of a variety of factors, such as shortages of workers or materials, transportation constraints, adverse weather, unforeseen difficulties or labor issues, any of which could prevent us from commencing operations as expected at our facilities.

Any new facility that we may complete may not operate as planned.

We recently completed construction of a new ethanol production facility in Fairbank, Iowa. Although we expect this facility to produce at a rate of 105 MMGPY, this facility, or any additional facility we construct in the future, may have operational problems affecting production and may not produce at its expected capacity.

Our Iowa Falls plant began operations in November 2004 and we were in the development stage for substantially all of 2004. As a result, a comparison of our results of operations for 2004 and 2005 may not be meaningful. By January 2005, our Iowa Falls plant was producing at a rate in excess of 50 MMGPY. The expansion of the Iowa Falls plant to its current production level of 100 MMGPY became operational in March 2006. In February 2005, we began construction of our Fairbank plant with a production capacity of 105 MMGPY. We commenced ethanol production at the Fairbank plant in May 2006. As a result, a comparison of our results of operations for 2005 and 2006 may not be meaningful due to our additional production capacity in 2006 compared to 2005. To the extent we acquire or develop additional production capacity in the future, the comparability of our results of operations will be further limited.

In addition, the THL Transactions will be accounted for utilizing the purchase method of accounting, which will result in a new valuation for our assets and liabilities to their fair values. This new basis of accounting will begin on the closing date of the THL Transactions. Allocations are subject to valuations as of the closing date of the THL Transactions. The allocation of the excess purchase price over the book value of the net assets acquired in the THL Transactions will be based, in part, on preliminary information which will continue to be subject to adjustment upon obtaining complete valuation information. In addition, we expect any future acquisitions will be accounted for using purchase accounting and therefore similar limitations regarding comparability of historical and future results could arise.

As a result of the Conversion, we will become a corporation and will be subject to federal and state corporate income taxes in the United States. Hawkeye Renewables, LLC is a limited liability company and is not subject to federal or state taxes. As a result, a comparison of our results of operations for 2005 and 2006 may not be meaningful due to the provision for income taxes that we must make following the Conversion.

Accordingly, our historical financial information may be of limited use in evaluating our historical performance and comparing it to other periods.

Our financial results may be adversely affected by potential future acquisitions, which could be difficult to identify and integrate and may divert the attention of key personnel, disrupt our business and dilute stockholder value.

As part of our business strategy, we may consider acquisitions of building sites, production facilities, storage or distribution facilities and selected infrastructure. We may not be able to identify suitable acquisition opportunities due to increased competition for such opportunities.

Acquisitions involve numerous risks, any of which could harm our business.

•: We may experience difficulties in integrating the operations, technologies, products, existing contracts, accounting processes and personnel of the target and realizing the anticipated synergies of the combined businesses.
•: We may experience difficulties in supporting and transitioning customers, if any, of the target company.
•: We may not be able to acquire or develop the infrastructure associated with new sites, including sufficient rail car leases, rail car siding space, or access to national rail networks.
•: Financial and management resources may be diverted from existing operations.
•: The price we pay or other resources that we devote may exceed the value we realize, or the value we could have realized if we had allocated the purchase price or other resources to another opportunity.
•: There are risks in entering new markets or areas in which we have limited or no experience or which are outside our core competencies.
•: We may lose key employees, customers and strategic alliances from either our current business or the business of the target.
•: We may assume unanticipated problems or latent liabilities, such as problems with the quality of the products of the target.
•: The target may not be able to generate sufficient revenue to offset acquisition costs.

Acquisitions also frequently result in the recording of goodwill and other intangible assets that are subject to potential impairments in the future that could harm our financial results and limit comparability between fiscal periods. In addition, if we finance acquisitions by issuing convertible debt or equity securities, our existing stockholders may be diluted, which could affect the market price of our common stock. If we fail to properly identify and evaluate acquisitions or investments, we may not achieve the anticipated benefits of any such acquisitions, and we may incur costs in excess of what we anticipate. The failure to successfully evaluate and execute acquisitions or investments or otherwise adequately address these risks could materially harm our business and financial results.

Growth in the sale and distribution of ethanol depends on changes to and expansion of related infrastructure which may not occur on a timely basis, if at all.

Substantial development of infrastructure will be required by persons and entities outside our control for our operations, and the ethanol industry generally, to grow. Areas requiring expansion include, but are not limited to:

•: additional rail car capacity;
•: additional storage facilities for ethanol;

•: increases in truck fleets capable of transporting ethanol within localized markets;
•: investment in refining and blending infrastructure to handle ethanol;
•: growth in service stations equipped to handle ethanol fuels; and
•: growth in the fleet of Flexible Fuel Vehicles—FFVs—capable of using fuel with significantly higher ethanol content than E10.

The substantial investments or government support required for these infrastructure changes and expansions may not be made or may not be made on a timely basis. Any delay or failure in making the changes to or expansion of infrastructure could weaken the demand or prices for our products, impede our delivery of products, impose additional costs on us or otherwise have a material adverse effect on our results of operations or financial position.

Disruptions to infrastructure could adversely affect our operations.

Our business depends on the continuing availability of rail, road, port, storage and distribution infrastructure. Any disruptions in this infrastructure network, whether caused by earthquakes, storms, other natural disasters or human error or malfeasance, could have a material adverse effect on our business. We rely upon others to maintain our rail line from our Fairbank plant to the national rail network, and any failure on their part to maintain the line could impede our delivery of products, impose additional costs on us or otherwise have a material adverse effect on our results of operations or financial condition. We may not continue to be able to obtain the necessary raw materials to produce ethanol and other co-products or to distribute our products to our customers.

We have a limited operating history and our business may not be as successful as we envision.

We were formed in October 2003 and commenced operations at our Iowa Falls plant in November 2004. Our new plant in Fairbank, Iowa commenced operations in May 2006. We have a limited operating history from which you can evaluate our business and prospects. In addition, our prospects must be considered in light of the risks and uncertainties encountered by an early-stage company and in rapidly evolving markets, such as the ethanol market, where supply and demand may change significantly over a short period.

Some of these risks relate to our potential inability to:

•: effectively manage our business and operations;
•: successfully maintain our low-cost structure as we expand the scale of our business; and
•: manage rapid growth in personnel and operations.

Our operations are complicated and, as the industry expands, we will face increasing competition to attract and retain key personnel, including plant managers. If we were to lose our key personnel our ability to operate our business would be adversely affected. If we cannot successfully mitigate these risks, our business and results of operations and financial condition would suffer.

Disruptions in the supply of, or significant increases in the price of, oil or natural gas could materially and adversely affect our business.

The production of ethanol, from the planting of corn to the distribution of ethanol to refiners, is highly energy-intensive. Significant amounts of oil and natural gas are required for the growing, fertilizing and harvesting of corn, as well as for the fermentation, distillation and transportation of ethanol and the drying of distillers grains. A serious disruption in the supply of oil, or significant further increases in the price of oil, could significantly reduce the availability of corn at our production facilities, increase our production costs and have a material adverse effect on our business.

We may not be able to compete effectively.

We compete with a number of other ethanol producers in the United States, including Archer Daniels Midland Company, VeraSun Energy Corporation, Aventine Renewable Energy, Inc., Cargill, Inc. and Abengoa Bioenergy Corp. A number of our competitors have substantially greater financial resources than we do. As of April 2006, the top ten domestic ethanol producers accounted for approximately 47.4% of all production capacity. Smaller competitors, made up mostly of farmer-owned cooperatives and independent firms consisting of groups of individual farmers and investors, also pose a threat, as they have been able to compete successfully in the ethanol industry. These smaller competitors operate smaller facilities which do not affect the local price of corn grown in the proximity to the facility as much as larger facilities like ours do. In addition, many of these smaller competitors are farmer-owned, receive greater government subsidies than we do and often require their farmer-owners to commit to selling them a certain amount of corn as a requirement of ownership. Over 50% of production capacity in our industry consists of smaller-sized facilities.

We expect competition to increase as the ethanol industry becomes more widely known and demand for ethanol increases. Most new ethanol plants under development across the country are individually owned. In addition, various investors could heavily invest in ethanol production facilities and oversupply the demand for ethanol, resulting in higher raw material costs and lower ethanol price levels that could adversely affect our results of operations and financial position.

We also face increasing competition from international suppliers. International suppliers produce ethanol primarily from sugar cane and have cost structures that may be substantially lower than ours. Although there is a $0.54 per gallon tariff (which is scheduled to expire in 2007) on foreign produced ethanol that is approximately equal to the blenders' credit, ethanol imports equivalent to up to 7% of total domestic production in any given year from various countries were exempted from this tariff under the Caribbean Basin Initiative to spur economic development in Central America and the Caribbean. Foreign suppliers of sugar cane-based ethanol may significantly increase their imports into the United States. Any increase in domestic or foreign competition could cause us to reduce our prices and take other steps to compete effectively, which could adversely affect our results of operations and financial position.

The domestic ethanol industry is highly dependent upon a myriad of federal and state legislation and regulation and any changes in legislation or regulation could adversely affect our results of operations and financial position.

The elimination or significant reduction in the blenders' credit could have a material adverse effect on our results of operations and financial position.

The cost of production of ethanol is made significantly more competitive with regular gasoline by federal tax incentives. Before January 1, 2005, the federal excise tax incentive program allowed gasoline distributors that blended ethanol with gasoline to receive a federal excise tax rate reduction for each blended gallon they sold. If the fuel was blended with 10% ethanol, the refiner/marketer paid $0.052 per gallon less tax, which equated to an incentive of $0.52 per gallon of ethanol. The $0.52 per gallon incentive for ethanol was reduced to $0.51 per gallon in 2005 and is scheduled to expire in 2010. The blenders' credit may not be renewed beyond 2010 or may be renewed on different terms. In addition, the blenders' credit, as well as other federal and state programs benefiting ethanol (such as tariffs), generally are subject to U.S. government obligations under international trade agreements, including those under the World Trade Organization Agreement on Subsidies and Countervailing Measures, and might be the subject of challenges thereunder, in whole or in part. The elimination or significant reduction in the blenders' credit may have a material adverse effect on our results of operations and financial position.

The elimination of or significant changes to the Freedom to Farm Act could have a material adverse effect on corn supplies.

In 1996, Congress passed the Freedom to Farm Act, which allows farmers continued access to government subsidies while reducing restrictions on farmers' decisions about land use. This act not only increased acreage dedicated to corn crops but also allowed farmers more flexibility to respond to increases in corn prices by planting greater amounts of corn. The elimination of this act could have a material adverse effect on the amount of corn available in future years and could reduce the farming industry's responsiveness to the increasing corn needs of ethanol producers.

Ethanol can be imported into the United States duty-free from some countries, which may undermine the domestic ethanol industry.

Imported ethanol is generally subject to a $0.54 per gallon tariff that was designed to offset the $0.51 per gallon ethanol incentive available under the federal excise tax incentive program for refineries that blend ethanol in their fuel. A special exemption from the tariff exists for ethanol imported from 24 countries in Central America and the Caribbean Islands, which is limited to a total of 7% of U.S. production per year. Imports from the exempted countries may increase as a result of new plants under development. Production costs for ethanol in these countries can be significantly less than in the United States and the duty-free import of lower price ethanol through the countries exempted from the tariff may reduce the demand for domestic ethanol and the price at which we sell our ethanol. Recently, in response to higher gasoline prices, a number of federal legislators have called for a reduction or temporary lifting of the tariff. Any changes in the tariff or exemption from the tariff could have a material adverse effect on our results of operations and financial position. In addition, the North America Free Trade Agreement, or NAFTA, which went into effect on January 1, 1994, allows Canada and Mexico to import ethanol duty-free or at a reduced rate. Canada is exempt from duty under certain NAFTA guidelines while Mexico's duty rate is $0.10 per gallon.

The effect of the Renewable Fuel Standard in the recent Energy Policy Act is uncertain.

The use of fuel oxygenates, including ethanol, was mandated through regulation, and much of the forecasted growth in demand for ethanol was expected to result from additional mandated use of oxygenates. Most of this growth was projected to occur in the next few years as the remaining markets switch from MTBE to ethanol. The recently enacted energy bill, however, eliminated the mandated use of oxygenates and established minimum nationwide levels of renewable fuels—ethanol, biodiesel or any other liquid fuel produced from biomass or biogas—to be included in gasoline. The legislation also included provisions for trading of credits for use of renewable fuels and authorized potential reductions in the Renewable Fuel Standard—RFS—minimum by action of a governmental administrator. In addition, the rules for implementation of the RFS and the energy bill are still under development. The favorable ethanol provisions in the energy bill may be adversely affected by these provisions or the enactment of additional legislation.

The legislation did not include MTBE liability protection sought by refiners. Ethanol producers have estimated that this lack of protection will result in accelerated removal of MTBE and increased demand for ethanol. Refineries, however, may use replacement additives other than ethanol, such as iso-octane, iso-octene and alkylate. Accordingly, the actual demand for ethanol may increase at a lower rate than production for estimated demand, resulting in excess production capacity in our industry, which would negatively affect our results of operations, financial position and cash flows.

Waivers of RFS minimum levels of renewable fuels included in gasoline could have a material adverse effect on our results of operations. Under the Energy Policy Act, the U.S. Department of Energy, in consultation with the Secretary of Agriculture and the Secretary of Energy, may waive

the renewable fuels mandate with respect to one or more states if the Administrator of the Environmental Protection Agency determines that implementing the requirements would severely harm the economy or the environment of a state, a region or the nation, or that there is inadequate supply to meet the requirement. Any waiver of the RFS with respect to one or more states would reduce demand for ethanol and could have a material adverse effect on our results of operations and financial condition.

We may be adversely affected by environmental, health and safety laws, regulations and liabilities.

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 the health and safety of our employees. Some of these laws and regulations require our facilities to operate under permits that are subject to renewal or modification. These laws, regulations and permits can require expensive emissions testing and pollution control equipment or operational changes to limit actual or potential impacts to the environment. A violation of these laws and regulations or permit conditions can result in substantial fines, natural resource damages, criminal sanctions, permit revocations and facility shutdowns. We may not have been, nor may we be at all times, in compliance with these laws, regulations or permits or that we have had or have all permits required to operate our business. We may be subject to legal actions brought by environmental advocacy groups and other parties for actual or alleged violations of environmental laws or our permits. In addition, we may be required 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 the properties that we own or operate and at off-site locations where we arrange for the disposal of hazardous substances. If these substances have been or are disposed of or released at sites that undergo investigation or remediation by regulatory agencies, we may be responsible under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, or CERCLA, or other environmental laws for all or part of the costs of investigation and remediation, and for damage to natural resources. We also may 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.

New laws, new interpretations of existing laws, increased governmental enforcement of environmental laws or other developments could require us to make additional significant expenditures. Continued government and public emphasis on environmental issues can be expected to result in increased future investments for environmental controls at our production facilities. Environmental laws and regulations, and interpretations thereof, applicable to our operations now or in the future, 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 position.

The hazards and risks, such as fires, natural disasters, explosions and abnormal pressures and blowouts, associated with producing and transporting our products also may result in personal injury claims or damage to property and third parties. We could sustain losses for uninsurable or uninsured risks, or in amounts in excess of existing insurance coverage. 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 position.

Our operating results may suffer if Eco-Energy Inc. (EEI) does not perform its obligations under existing arrangements or if we are unable to achieve results comparable to those achieved by selling ethanol through EEI in the event we begin marketing and selling our ethanol directly to our customers.

We sell all our ethanol production to EEI for resale to third parties. While EEI has established relationships with many of the leading end-users of ethanol products, we have limited control over its sales efforts. Our results of operations would be adversely affected if EEI ceased to purchase our ethanol or if EEI does not obtain the most favorable pricing for our ethanol. In addition, we may not be able to renew our contract with EEI on the same or similar terms or enter into a similar contract upon its expiration. If we begin to market or sell our ethanol directly to customers, we may incur increased costs and may not be able to achieve results comparable to those achieved by having our ethanol sold by EEI. Any failure to successfully market our ethanol on our own would have an adverse effect on our results of operations.

We currently are unable to accurately predict what our short-term and long-term effective tax rates will be in the future. In addition, in connection with the Conversion, we will enter into a tax receivables agreement obligating us to pay our current owners amounts equal to certain tax benefits we receive as a result of the Transactions.

After the Conversion, we will become subject to corporate income taxes in the United States. We have had limited historical profitability upon which to base our estimate of future short-term and long-term effective tax rates. Significant judgment is required in determining our worldwide provision for income taxes and, in the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. Our effective tax rates could be adversely affected by changes in the mix of earnings in locations with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities or changes in tax laws, as well as other factors. Accordingly, our judgments may be subject to audits or reviews by tax authorities in state and federal jurisdictions, which could adversely affect our income tax provisions.

In addition, in connection with the Conversion, we will enter into a tax receivables agreement with our current owners. Pursuant to this agreement, we will be required to pay to such persons the amount by which our income taxes are actually reduced as a result of the increase in the tax basis of our tangible and intangible assets attributable to the Transactions and as a result of certain other tax benefits related to our making payments under the tax receivables agreement. We will be required by the tax receivables agreement to pay the entire amount of such reduction to THL and Hawkeye Holdings, L.L.C. While the actual amount and timing of any payments under this agreement will vary depending upon a number of factors, we expect that, as a result of the size of the increase in the tax basis of our tangible and intangible assets, during the amortization period for such assets, the payments to be made to these persons may be substantial.

Our level of indebtedness could adversely affect our ability to react to changes in our business, and we may be limited in our ability to use debt to fund future capital needs.

As of March 31, 2006, after giving pro forma effect to the THL Transaction and the Conversion, our total debt would have been approximately $ million. Our substantial indebtedness could have important consequences for you by adversely affecting our financial position. Our substantial indebtedness could:

•: require us to dedicate a substantial portion of our cash flow from operations to payments with respect to our indebtedness, thereby reducing the availability of our cash flow for working capital, capital expenditures and other general corporate expenditures;
•: increase our vulnerability to adverse general economic or industry conditions;

•: limit our flexibility in planning for, or reacting to, competition or changes in our business or industry;
•: limit our ability to borrow additional funds;
•: restrict us from building new facilities, making strategic acquisitions, introducing new products or services or exploiting business opportunities; and
•: place us at a competitive disadvantage relative to competitors that have less debt or greater financial resources.

Our ability to make payments on and refinance our indebtedness will depend on our ability to generate cash from our operations. Our ability to generate cash from operations is subject in large part, to general economic, competitive, legislative and regulatory factors and other factors that are beyond our control. We may not be able to generate enough cash flow from operations nor obtain enough capital to service our debt or fund our planned capital expenditures.

Risks Relating to the Offering and Ownership of our Common Stock

There is no existing market for our common stock, and we do not know whether a market will develop.

Prior to this offering, our common stock has not been traded on a public market, and there are few public companies with substantial ethanol operations. We intend to apply to list our common stock on the New York Stock Exchange. A trading market may not develop, or, to the extent a trading market does develop, such a market may not be liquid. An illiquid market will limit your ability to resell shares of our common stock. The initial public offering price for the shares will be determined by negotiations between us and the underwriters and may not be indicative of prices that will prevail in the open market following this offering. Consequently, you may not be able to sell shares of our common stock at prices equal to or greater than the price paid by you in this offering.

The price of our common stock may be volatile.

The trading price of our common stock following this offering is likely to be highly volatile and could be subject to fluctuations in response to a number of factors beyond our control. Some of these factors are:

•: our results of operations and the performance of our competitors;
•: the public's reaction to our press releases, our other public announcements and our filings with the SEC;
•: changes in earnings estimates or recommendations by research analysts who follow us or other companies in our industry;
•: changes in general economic conditions;
•: commencement or involvement in litigation;
•: disruption of our operations;
•: any major change in our management team; and
•: other developments affecting us, our industry or our competitors.

In recent years the stock market has experienced significant price and volume fluctuations. These fluctuations may be unrelated to the operating performance of particular companies. These broad market fluctuations may cause declines in the market price of our common stock. The price of our common stock could fluctuate based upon factors that have little or nothing to do with our company or its performance, and those fluctuations could materially reduce our common stock price.

We do not intend to pay dividends on our common stock.

We do not anticipate paying any cash dividends on our common stock in the foreseeable future. We currently anticipate that we will retain all of our available cash, if any, for use as working capital and for other general corporate purposes, including to service our debt and to fund the operation and expansion of our business. Any payment of future dividends will be at the discretion of our board of directors and will depend on, among other things, our earnings, financial condition, capital requirements, level of indebtedness, statutory and contractual restrictions applying to the payment of dividends and other considerations that the board of directors deems relevant. Investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize a return on their investment. Investors seeking cash dividends should not purchase our common stock.

The interests of our controlling stockholders could differ from the interests of our public stockholders.

Following the closing of this offering, THL will own % of our common stock. The interests of these investors could conflict with your interests. Until such time, if ever, that there is a significant decrease in the percentage of outstanding shares held by THL, they will be able to control all matters requiring stockholder approval, including the election of directors, the adoption of amendments to our certificate of incorporation and approval of significant transactions. In addition, this concentration of ownership may delay or prevent a change in control of our company or make some transactions more difficult or impossible without the support of these stockholders.

Certain stockholders' shares are restricted from immediate resale but may be sold into the market in the near future, which could cause the market price of our common stock to drop significantly.

After this offering, we will have outstanding shares of common stock ( shares if the underwriters exercise their over-allotment option in full). Of these shares, the shares we are selling in this offering ( shares if the underwriters exercise their over-allotment option in full) will be freely tradable without restriction under the Securities Act except for any shares purchased by one of our "affiliates" as defined in Rule 144 under the Securities Act. All of the shares outstanding other than the shares sold in this offering will be "restricted securities" within the meaning of Rule 144 under the Securities Act and subject to lock-up arrangements.

In connection with this offering, we, our directors and executive officers, substantially all of our existing stockholders have entered into lock-up agreements with the underwriters. Under these agreements, subject to exceptions, we may not issue any new shares of common stock, and those holders of stock may not, directly or indirectly, offer, sell, contract to sell, pledge or otherwise dispose of or hedge any common securities convertible into or exchangeable for shares of common stock, or publicly announce the intention to do any of the foregoing, without the prior written consent of the underwriters for a period of 180 days from the date of this prospectus. Upon the expiration of these lock-up agreements, shares ( shares if the underwriters exercise their over-allotment option in full) will be eligible for sale in the public market under Rule 144 of the Securities Act, subject to volume limitations and other restrictions contained in Rule 144. If these holders sell their shares after this period, the price of our common stock could decline. In addition, the sale of these shares could impair our ability to raise capital through the sale of additional equity securities.

Provisions in our charter documents may delay or prevent our acquisition by a third party.

Some provisions in our certificate of incorporation and bylaws may be deemed to have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that a stockholder might deem to be in his or her best interest. The existence of these provisions could limit the price that investors might be willing to pay in the future for shares of our common stock.

We will be a "controlled company" within the meaning of the New York Stock Exchange rules and, as a result, will qualify for and will rely on exemptions from certain corporate governance requirements.

Upon completion of this offering, THL will continue to control a majority of the voting power of our outstanding common stock and we will be a "controlled company" within the meaning of the New York Stock Exchange corporate governance standards. Under the New York Stock Exchange rules, a company of which more than 50% of the voting power is held by another person or group of persons acting together is a "controlled company" and may elect not to comply with certain New York Stock Exchange corporate governance requirements, including the requirements that:

•: a majority of the board of directors consist of independent directors;
•: the nominating and corporate governance committee be composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities;
•: the compensation committee be composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities; and
•: there be an annual performance evaluation of the nominating and corporate governance and compensation committees.

Following this offering, if we qualify, we intend to elect to be treated as a controlled company and thus utilize these exemptions. As a result, although we will have adopted charters for our audit, nominating and corporate governance and compensation committees and intend to conduct annual performance evaluations for these committees, our board may not consist of a majority of independent directors nor may our nominating and corporate governance and compensation committees consist of independent directors. Accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of the New York Stock Exchange corporate governance requirements.

You will experience immediate and significant dilution in the tangible book value of the shares you purchase in this offering.

If you invest in common stock, your interest will be diluted to the extent of the difference between the public offering price per share of our common stock and the as adjusted net tangible book value per share of our common stock after this offering. Based upon the issuance and sale of shares of our common stock at the offering price of $ per share, you will incur immediate dilution of approximately $ in the net tangible book value per share if you purchase common stock in the offering. See "Dilution."

The requirements of being a public company, including compliance with the reporting requirements of the Exchange Act and the requirements of the Sarbanes-Oxley Act, may strain our resources, increase our costs and distract management, and we may be unable to comply with these requirements in a timely or cost-effective manner.

When our common stock is publicly traded, we will need to comply with laws, regulations and requirements, certain corporate governance provisions of the Sarbanes-Oxley Act of 2002, related regulations of the SEC and requirements of the New York Stock Exchange, with which we are not required to comply as a private company. Complying with these statutes, regulations and requirements will occupy a significant amount of the time of our board of directors and management, will require us to have additional finance and accounting staff and will increase our costs and expenses by approximately $2.0 million per year. We will need to:

•: institute a more comprehensive compliance function;
•: establish new internal policies, such as those relating to disclosure controls and procedures and insider trading;

•: design, establish, evaluate and maintain a system of internal controls over financial reporting in compliance with the requirements of Section 404 of the Sarbanes-Oxley Act and the related rules and regulations of the SEC and the Public Company Accounting Oversight Board;
•: prepare and distribute periodic reports in compliance with our obligations under the federal securities laws;
•: involve and retain to a greater degree outside counsel and accountants in the above activities; and
•: establish an investor relations function.

If we are unable to accomplish these objectives in a timely and effective fashion, our ability to comply with our financial reporting requirements and other rules that apply to reporting companies could be impaired. In addition, we also expect that being a public company subject to these rules and regulations will require us to modify our director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee, and qualified executive officers.

Our management and auditors have identified a material weakness in the design or operation of our internal controls that, if not properly remediated, could result in material misstatements in our financial statements in future periods.

With respect to the audit of the 2005 financial statements of Hawkeye Holdings, L.L.C., our independent registered public accounting firm, KPMG LLP, issued a letter to the board of directors in which they identified a material weakness relating to our control over the financial reporting process. Our failure to maintain adequate control over the financial reporting process has resulted in adjustments to our financial statements related to the accounting for and reporting of certain derivative transactions and reporting of cash flow information.

A material weakness is defined by the Public Company Accounting Oversight Board (United States) as a significant deficiency, or combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. A significant deficiency is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a more than inconsequential misstatement of the financial statements will not be prevented or detected. A control deficiency exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis.

In response to these matters, we need to implement additional financial and management controls and hire additional and/or more experienced accounting and finance staff experienced in addressing complex accounting matters applicable to public companies. If we are unable to improve our financial and management controls, and hire additional and/or more experienced accounting and finance staff experienced in addressing complex accounting matters applicable to public companies, in each case in a timely and effective manner, our ability to comply with the accounting and financial reporting requirements and other rules that apply to public companies would be impaired.

If the remedial policies and procedures we implement are insufficient to address the identified material weakness, or if additional significant deficiencies or material weaknesses in our internal controls are discovered in the future, we may fail to meet our future reporting obligations, our financial statements may contain material misstatements and our operating results may be adversely affected. Any such failure could also adversely affect the results of the periodic management evaluations and annual auditor attestation reports regarding the effectiveness of our "internal control over financial

reporting," which will be required once the SEC's rules under Section 404 of the Sarbanes-Oxley Act of 2002 become applicable to us.

A failure to achieve and maintain effective internal control over financial reporting in accordance with the rules of the SEC could harm our business and operating results and result in a loss of investor confidence in our financial reports, which could have a material adverse effect on our business and stock price.

We currently rely primarily upon a substantive review by our management to help ensure the accuracy of our financial reports. Section 404 of the Sarbanes-Oxley Act requires that we design and implement internal controls over financial reporting, as well as perform an annual management assessment of the effectiveness of our internal control over financial reporting. It also requires that we engage our independent registered public accounting firm to perform an annual audit of our assessment and the effectiveness of our internal control over financial reporting. If we fail to implement the requirements of Section 404 in a timely manner, we might be subject to sanctions or investigation by regulatory authorities such as the SEC or the New York Stock Exchange. In addition, failure to comply with Section 404 or a report of a material weakness may cause investors to lose confidence. Accordingly, any failure to establish and maintain effective internal controls could have a material adverse effect on our business, operating results and stock price.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
AND INDUSTRY AND MARKET DATA

This prospectus contains "forward-looking statements" that represent our beliefs, projections and predictions about future events. All statements other than statements of historical fact are "forward-looking statements" for purposes of federal and state securities laws, including: any projections of earnings, revenue or other financial items; any statements of the plans, strategies and objectives of management for future operations; any statements concerning proposed new programs, products or other developments; any statements regarding future economic conditions or performance; any statements of management's beliefs, goals, strategies, intentions and objectives; and any statements of assumptions underlying any of the foregoing. Words such as "may," "will," "should," "could," "would," "predicts," "potential," "continue," "expects," "anticipates," "future," "intends," "plans," "believes," "estimates," and similar expressions, as well as statements in future tense, identify forward-looking statements.

These statements are necessarily subjective and involve known and unknown risks, uncertainties and other important factors that could cause our actual results, performance or achievements, or industry results, to differ materially from any future results, performance or achievement described in or implied by such statements. Actual results may differ materially from expected results described in our forward-looking statements, including with respect to correct measurement and identification of factors affecting our business or the extent of their likely impact, the accuracy and completeness of the publicly available information with respect to the factors upon which our business strategy is based or the success of our business.

Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of whether, or the times by which, such performance or results may be achieved. Forward-looking statements are based on information available at the time those statements are made and management's belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to, those factors discussed under the headings "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Business" or elsewhere in this prospectus.

We obtained the industry, market and competitive position data used throughout this prospectus from our own research, internal surveys and studies conducted by third parties, independent industry associations or general publications and other publicly available information. In particular, we have based much of our discussion of the ethanol industry, including government regulation relevant to the industry and forecasted growth in demand, on information published by the RFA, the national trade association for the U.S. ethanol industry. Independent industry publications and surveys generally state that they have obtained information from sources believed to be reliable, but do not guarantee the accuracy and completeness of such information. Further, because the RFA is a trade organization for the ethanol industry, it may present information in a manner that is more favorable to that industry than would be presented by an independent source. Forecasts are particularly likely to be inaccurate, especially over long periods of time and in a relatively new and rapidly developing industry.

USE OF PROCEEDS

The net proceeds from the sale of the shares of common stock offered by us will be approximately $ million, assuming a public offering price of $ per share, the mid-point of the price range on the cover page of this prospectus and after deducting the underwriting discounts and estimated offering expenses payable by us. If the underwriters exercise their over-allotment option in full, we will receive additional net proceeds of approximately $ million after deducting estimated underwriting discounts and commissions.

We will use approximately $ of the net proceeds from this offering to redeem our 8% mandatorily redeemable preferred stock and the balance for funding our growth strategy, debt repayment or working capital needs.

To the extent we use a portion of our net proceeds from this offering to repay debt, we would repay $ million of our 2006 senior secured term loan. The interest rates with respect to term loans under our 2006 senior secured credit facilities are based on, at our option, adjusted LIBOR plus % or a Dollar base rate plus %. Our term loan facility has a -year term. We used borrowings from our term loan facility to consummate the THL Transactions. See "Description of Indebtedness—2006 Senior Secured Credit Facilities." Certain of the underwriters or their affiliates are or may become lenders under our new senior secured credit facilities and as such, will or may, as applicable, receive a portion of the proceeds of this offering, which will be used to partially repay term loans thereunder.

Assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same, after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us in connection with the offering, a $1.00 increase (decrease) in the assumed public offering price of $ per share would increase (decrease) the amount of proceeds from this offering available to be used for funding our growth strategy, debt repayment or working capital needs by $ million.

DIVIDEND POLICY

Prior to the closing of this offering, Hawkeye Intermediate LLC intends to make a cash distribution of approximately $ million to the members of Hawkeye Intermediate LLC to enable them to meet their estimated income tax obligations for the period prior to the date of the Conversion. The amount of this distribution will be based on Hawkeye Intermediate LLC's estimated net taxable income from the date of the THL Transactions to the date of the Conversion. Investors in the offering will not receive this distribution.

After the completion of this offering, we do not anticipate declaring or paying any cash dividends on our common stock in the foreseeable future. We currently anticipate that we will retain all of our available cash, if any, for use as working capital and for other general corporate purposes, including to service our debt and to fund the operation and expansion of our business. Payment of future dividends, if any, will be at the discretion of our board of directors and will depend on many factors, including general economic and business conditions, our strategic plans, our financial results and condition, legal requirements and other factors as our board of directors deems relevant. Our 2006 senior secured credit facilities impose restrictions on our ability to pay dividends, and thus our ability to pay dividends on our common stock will depend upon, among other things, our level of indebtedness at the time of the proposed dividend and whether we are in default under any of our debt instruments.

CAPITALIZATION

The following table sets forth our capitalization as of March 31, 2006:

•: on an actual basis;
•: as adjusted to give effect to the THL Transactions;
•: as further adjusted to give effect to the Conversion; and
•: on a pro forma as adjusted basis to reflect this offering and the application of the net proceeds therefrom.

You should read this table in conjunction with "Use of Proceeds," "Selected Consolidated Historical Financial Data," "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Unaudited Pro Forma Consolidated Financial Data," our consolidated financial statements and, in each case, the related notes included elsewhere in this prospectus.

The pro forma as adjusted information discussed above is illustrative only and following completion of this offering will be adjusted based on the actual initial public offering price and other terms of this offering determined at pricing.
(2): As of March 31, 2006, on a pro forma basis, we would have had total borrowing capacity of approximately $ million under our $50.0 million revolving credit facility entered into in connection with the THL Transactions.

DILUTION

If you invest in our common stock, your interest in the book value of our shares of common stock will be diluted to the extent of the difference between the public offering price per share of our common stock and the as adjusted net tangible book value per share of our common stock after this offering. We calculate net tangible book value per common share by dividing our net tangible book value, which equals total assets less intangible assets (including goodwill and unamortized debt issuance costs) and total liabilities, by the number of shares outstanding. Our net tangible book value at , 2006 was $ , or $ per common share, based upon shares outstanding.

After giving effect to the sale of shares of common stock in this offering at an assumed offering price of $ per share (the mid-point of the price range on the cover page of this prospectus), and after deducting the estimated underwriting discount and estimated offering expenses payable by us, our as adjusted net tangible book value as of , 2006 would have been approximately $ million, or $ per common share. This represents an immediate increase in net tangible book value of $ per common share to existing stockholders, and an immediate dilution in net tangible book value of $ per common share to new investors, or approximately % of the offering price of $ per common share. The following table illustrates this dilution on a per common share basis:

			Per Share
Assumed initial public offering price			$
	Net tangible book value (deficit) at March 31, 2006 before giving effect to the offering	$
	Increase in net tangible book value attributable to this offering

Pro forma tangible book value after giving effect to this offering

Dilution to new investors			$

Assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same, after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us in connection with the offering, a $1.00 increase (decrease) in the assumed public offering price of $ per share would increase (decrease) the increase in net tangible book value attributable to this offering by $ per share and the dilution to new investors by $ per share and decrease (increase) the pro forma net tangible book deficit after this offering by $ per share.

As of , 2006, there were shares of our common stock outstanding held by stockholders of record. If the underwriters' over-allotment option is exercised in full, the number of shares of common stock held by existing stockholders will be reduced to , or % of the aggregate number of shares of common stock outstanding after this offering, and the number of shares of common stock held by new investors will be increased to , or % of the aggregate number of shares of common stock outstanding after this offering.

The following table summarizes on the basis described above, as of , 2006, the difference between the number of shares of common stock purchased from us, the total consideration paid to us, and the average price per share paid by the existing shareholders and by new investors, at the initial public offering price of $ per share, which is the mid-point of the price range set forth on

the cover of this prospectus, before deducting underwriting discounts and commissions and estimated offering expenses payable by us:

The following table sets forth certain consolidated historical financial data for Hawkeye Holdings, L.L.C. We have derived the selected consolidated historical financial data for the period from our inception on October 22, 2003 to December 31, 2003, as of and for the years ending December 31, 2004 and 2005, from the audited consolidated financial statements of Hawkeye Holdings, L.L.C. included elsewhere in this prospectus. We have derived the selected consolidated historical financial data as of and for the three months ended March 31, 2005 and 2006 from the unaudited consolidated financial statements of Hawkeye Holdings, L.L.C. included elsewhere in this prospectus. In our opinion, our unaudited consolidated interim financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments, consisting of normal recurring adjustments, that management considers necessary for a fair presentation of the financial position and results of operations for these periods. The results of any interim period are not necessarily indicative of the results that may be expected for any other interim period or for the full fiscal year, and the historical results set forth below do not necessarily indicate results expected for any future period. The selected consolidated historical financial data should be read in conjunction with the discussion under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations," and the historical consolidated financial statements and accompanying notes included elsewhere in this prospectus. Comparison of results of operations for 2005 and 2006 and for periods within those years may not be meaningful due to increases in our production capacity attributable to the timing of the initial construction and subsequent expansion of our Iowa Falls plant and the development of our Fairbank plant.

(1): Period from October 22, 2003, the date of inception, to December 31, 2003.
(2): Substantially all of the miscellaneous income was derived through a government program established through the United States Department of Agriculture that provided cash payments for companies that generate increases in bioenergy production, such as ethanol, from previous production levels. We do not expect any further income attributable to this program.
(3): Represents realized loss or gain on exchange traded commodity option transactions. See note 1 to our audited consolidated financial statements.

(4)

EBITDA is defined as net income (loss) before interest expense (net of interest income), income tax expense, depreciation and amortization. Amortization of debt issuance costs and debt discount are included in interest expense. EBITDA is not a measure of financial performance under accounting principles generally accepted in the U.S., or GAAP, and should not be considered an alternative to net income, 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 has its limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of the limitations of EBITDA are:

•: EBITDA does not reflect our cash used for capital expenditures;
•: Although depreciation and amortization are non-cash charges, the assets being depreciated or amortized often will have to be replaced and EBITDA does not reflect the cash requirements for replacements;
•: EBITDA does not reflect changes in, or cash requirements for, our working capital requirements;
•: EBITDA does not reflect the cash necessary to make payments of interest or principal on our indebtedness; and
•: EBITDA includes non-recurring payments to us which are reflected in other income.

Because of these limitations, EBITDA should not be considered as a measure of discretionary cash available to us to service our debt or to invest in the growth of our business. We compensate for these limitations by relying on our GAAP results as well as on our EBITDA. Management uses EBITDA as a measure of our performance and ability to generate cash necessary to meet our future requirements for debt service, capital expenditures, working capital and taxes. We also believe that EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties to evaluate companies in our industry. Because not all companies use identical calculations, this presentation of EBITDA may not be comparable to other similarly titled measures for other companies. Also, the amounts shown for EBITDA as presented herein differ from the amounts calculated under the definition of Adjusted EBITDA used in our debt instruments, which further adjust for certain cash and non-cash charges and are used to determine compliance with financial covenants and our ability to engage in certain activities such as incurring additional debt and making acquisitions.

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA

The following unaudited pro forma consolidated data for the year ended December 31, 2005 and as of and for the three months ended March 31, 2006 have been derived by application of pro forma adjustments to the historical consolidated audited and unaudited financial statements of Hawkeye Holdings, L.L.C. included elsewhere in this prospectus.

The unaudited pro forma consolidated statements of operations for the year ended December 31, 2005 and for the three months ended March 31, 2006 give effect to the Transactions, as if each transaction had occurred on January 1, 2005.

The unaudited pro forma consolidated balance sheet as of March 31, 2006, gives effect to the Transactions as if each transaction had occurred as of March 31, 2006.

The assumptions underlying the pro forma adjustments are described in the accompanying notes which should be read in conjunction with these unaudited pro forma consolidated financial statements.

The pro forma adjustments related to the purchase price allocation and financing of the THL Transactions are preliminary and based on information available to date and are subject to revision as additional information becomes available. The actual purchase accounting adjustments described in the accompanying notes will be made as of the closing date of the THL Transactions and may differ from those reflected in these unaudited pro forma consolidated financial statements. Revisions to the preliminary purchase price allocation and financing of the THL Transactions may have a significant impact on the pro forma amounts of total assets, total liabilities and shareholders' equity, cost of goods sold, selling, general and administrative expenses, depreciation and amortization and interest expense.

The unaudited pro forma adjustments are based upon available information and assumptions that management believes are reasonable under the circumstances. The unaudited pro forma consolidated financial data is included for informational purposes only and does not purport to represent what our results of operations or financial condition would have been had the THL Transactions, the Conversion and this offering actually occurred on the dates indicated, nor does it purport to project the results of our operations or financial condition for any future period or as of any future date.

The unaudited pro forma consolidated statements of operations do not give effect to one-time effects of events that are directly attributable to the Transactions. As a corporation, we will be subject to federal and state income taxes. Hawkeye Holdings, L.L.C. is a limited liability company and has not been subject to federal or state taxes.

The unaudited pro forma consolidated financial data should be read in conjunction with the information contained in "Selected Consolidated Historical Financial Data," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Certain Relationships and Related Transactions" and the consolidated financial statements and the related notes thereto appearing elsewhere in this prospectus.

Hawkeye Holdings Inc.
Notes to the Unaudited Pro Forma Consolidated Balance Sheet

(1)

Reflects the consolidated historical financial position of Hawkeye Holdings, L.L.C. as of March 31, 2006.

(2)

Pro forma adjustments to record the THL Transactions reflect:

•

a total decrease in cash, restricted cash and the interest reserve escrow of $77.3 million representing amounts distributed to the members of Hawkeye Holdings, L.L.C. after repayment of our existing credit facility and the removal of the related restrictions on the use of this cash;

•

an increase in inventory of $1.0 million representing the step-up to fair value as a result of the purchase price allocation;

•

an increase in goodwill of $856.7 million as a result of the application of purchase accounting;

•

a decrease in other assets of $3.4 million representing proceeds received from the termination of an interest rate swap agreement upon repayment of our existing credit facility and distributed to the members of Hawkeye Holdings, L.L.C.

•

a net increase in debt issuance costs of $16.6 million relating to the write-off of existing unamortized debt issuance costs of $8.4 million as a result of the repayment of the related debt, and the capitalization of $25.0 million in financing fees incurred in connection with the 2006 senior secured credit facilities;

•

an increase in accrued expenses of $37.3 million, representing the estimated fair value of certain forward sales contracts determined to be below market;

•

a decrease in deferred revenue of $1.3 million representing an adjustment to fair value as a result of the purchase price allocation;

•

a net increase in indebtedness for borrowed money of $409.4 million, representing $650.0 million of debt incurred under the 2006 senior secured credit facilities as a result of the THL Transactions, less existing debt repaid of $240.6 million;

•

an increase of $351.0 million in redeemable preferred members' interests as a result of the THL Transactions; and

•

a net increase in common members' interest of $12.3 million consisting of:

•: $77.3 million of cash on hand, including restricted cash and the interest reserve escrow, distributed to the members of Hawkeye Holdings, L.L.C.;
•: the write-off of existing debt issuance costs of $8.4 million;
•: the elimination of our historical deficit of $59.0 million (after consideration of the two immediately preceding bullets above); and
•: issuance of common members' interests of $39.0 million.

The final allocation of the purchase price will be determined at a later date based on a comprehensive final evaluation of the tangible and intangible assets acquired and liabilities assumed at the date of the THL Transactions. The preliminary allocation is summarized in the following table:

		(In millions)
Calculation of the purchase price:
	Proceeds to Hawkeye Holdings, L.L.C.	$	764
	Repayment of existing debt		241
	Direct acquisition costs, excluding capitalized financing fees of $25.0 million		11

	Total purchase price	$	1,016

Allocation of purchase price:
	Current assets	$	11
	Property, plant and equipment		205
	Goodwill		853
	Other assets		8
	Current liabilities		(60	)
	Minority interest		(1	)

	Total purchase price	$	1,016

No deferred tax assets or liabilities have been established as Hawkeye Intermediate LLC is a pass-through entity for federal and state income taxes.

(3)

Pro forma adjustments to record the Conversion reflect:

•: the recognition of a one-time, non-cash credit to the income tax provision to recognize previously unrecognized deferred tax assets of approximately $ million upon becoming a corporation immediately before the effectiveness of the registration statement of which this prospectus is a part. This deferred tax liability primarily results from the excess of the book basis over the tax basis of certain of our intangible assets. We expect to realize future reductions in our current tax expense as these assets are amortized and deducted from taxable income on our tax returns.

(4)

Pro forma adjustments to record this offering reflect:

•

a net increase in cash of $ million consisting of:

•: proceeds raised in this offering of $ million from the issuance of million shares of our common stock to the public,
•: the use of $ million from the proceeds of this offering to repay a portion of our outstanding indebtedness under our 2006 senior secured credit facilities,
•: the use of $ million from the proceeds of this offering to redeem the redeemable preferred stock,
•: the use of $ million from the proceeds of this offering to pay estimated transaction costs to be incurred by us, and
•: the use of $ million to fund working capital and potential growth opportunities;

•

a decrease in notes payable of $ million representing the use of proceeds from this offering to repay a portion of our outstanding indebtedness under our 2006 senior secured credit facilities;

•

a decrease in redeemable preferred stock of $ million reflecting the use of proceeds from this offering to redeem the redeemable preferred stock; and

•: a net increase in stockholders'/members' equity (deficit) of $ million consisting of proceeds raised of $ million from the issuance of million shares of our common stock to the public, and the use of $ million to pay estimated transaction costs to be incurred by us.

(5): Restricted cash consists of amounts that are reserved for specific uses under our existing credit facility.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the "Selected Consolidated Historical Financial Data" and our consolidated financial statements and accompanying notes included elsewhere in this prospectus. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this prospectus, particularly in "Risk Factors."

Overview

As a result of the expansion of our Iowa Falls plant, the development of our Fairbank plant and the Transactions, our historical financial information is not comparable to our current financial condition and results of operations. Prior to November 2004, we did not have any business operations and were in the development stage.

Our Iowa Falls plant began operations in November 2004. As a result, a comparison of our results of operations for 2004 and 2005 may not be meaningful. By January 2005, our Iowa Falls plant was producing at a rate in excess of 50 MMGPY. Our results of operations for 2005 reflect the operations of our Iowa Falls plant at its initial production capacity without giving effect to the expansion. The expansion of the Iowa Falls plant to its current production level of 100 MMGPY became operational in March 2006. Our results of operations for the first quarter of 2006 reflect the expansion for one week. In February 2005, we began construction of our Fairbank plant with a production capacity of 105 MMGPY. We commenced ethanol production at the Fairbank plant in May 2006. Our results of operations for the first quarter of 2006 do not reflect the operations of the Fairbank plant and our results of operations for the second quarter of 2006 reflect the operations of the Fairbank plant for one month. As a result, a comparison of our results of operations for 2005 and 2006 and for periods within those years may not be meaningful due to the increase in our production capacity described above. To the extent we acquire or develop additional production capacity in the future, the comparability of our results of operations will be further limited.

In addition, the THL Transactions will be accounted for utilizing the purchase method of accounting, which will result in a new valuation for the assets and liabilities of Hawkeye Renewables, LLC based on their fair values. This new basis of accounting will begin on the closing date of the THL Transactions. Allocations are subject to valuations as of the closing date of the THL Transactions. The allocation of the excess purchase price over the book value of the net assets acquired in the THL Transactions will be based, in part, on preliminary information, which will continue to be subject to adjustment upon obtaining complete valuation information. In addition, we expect any future acquisitions will be accounted for using purchase accounting and therefore similar limitations regarding comparability of historical and future results could arise. Accordingly, our historical financial information may be of limited use in evaluating our historical performance and comparing it to other periods.

Components of Revenues and Expenses

Total revenues

Our primary source of revenue is the sale of ethanol. Sales of ethanol accounted for 90.1% of our total revenues in 2004 and 89.1% of our total revenues in 2005. We also receive revenue from the sale

of distillers grains, which are a residual coproduct of the processed corn and sold as animal feed. The selling prices we realize for our ethanol are largely determined by the market supply and demand for ethanol, which, in turn, is influenced by industry factors over which we have little if any control. See "Industry Outlook."

Ethanol prices are extremely volatile. In early 2005, ethanol prices decreased due to a perceived over-supply of ethanol, which had a negative effect on our operating results in the first quarter of 2005. Since that time, ethanol prices have recovered due to increased gasoline prices, legislative changes and continued oil refining capacity shortages, resulting in an average realized price for 2005 that is $0.10 per gallon higher than the prior year period. The spot ethanol price on the Chicago Board of Trade—CBOT—rose from $1.19 per gallon in May 2005 to $2.08 per gallon as of December 31, 2005. The following table provides information on ethanol prices for the periods shown.

Cost of goods sold and gross profit

Our gross profit is derived from our total revenues less our cost of goods sold. Our cost of goods sold is affected by the cost of corn and natural gas. Both corn and natural gas are subject to volatile market conditions as a result of weather, market demand, regulation and general economic conditions.

We define our net corn cost as the cost of corn less distillers grains sales. We define our net cost of goods sold as cost of goods sold less distillers grains sales.

Corn is our most significant raw material cost. The price of corn is influenced by weather conditions and other factors affecting crop yields, farmer planting decisions and general economic, market and regulatory factors. These factors include government policies and subsidies with respect to agriculture and international trade, and global and local demand and supply. The spot price of corn tends to rise during the Spring planting season in May and June and tends to decrease during the Fall harvest in October and November. The following table provides information on corn prices for the periods shown.

Corn $/Bushel (January 2000–May 2006)

We purchase natural gas to power steam generation in our ethanol production process and to dry our distillers grains. Natural gas represents our second largest operating cost after corn and natural gas prices are extremely volatile. The following table provides information on natural gas prices for the periods shown.

Spread between ethanol and corn prices

Our gross margins depend principally on our crush spread—the difference between the price of a gallon of ethanol and the price of the amount of corn required to produce a gallon of ethanol. Using dry mill technology, each bushel of corn produces approximately 2.8 gallons of ethanol.

In recent periods, the spread between ethanol and corn prices has been at historically high levels, driven in large part by high oil prices and historically low corn prices resulting from continuing record corn yields and acreage. Any increase or reduction in the spread between ethanol and corn prices, whether as a result of changes in the price of ethanol or corn, will have an effect on our financial performance.

The following graph sets forth the crush spread for recent periods and illustrates the volatility in ethanol and corn market prices and the impact of that volatility on the crush spread.

Selling, general and administrative expenses

Selling, general and administrative expenses consist of salaries and benefits paid to our administrative employees, expenses relating to third-party services, insurance, travel, marketing and other expenses. We expect selling, general and administrative expenses to increase significantly in connection with our expansion, which will require us to hire more personnel. We also anticipate incurring additional expenses of approximately $2.0 million as a public company following the completion of this offering as a result of additional legal and corporate governance expenses, including: costs associated with compliance with Section 404 of the Sarbanes-Oxley Act; salary and payroll-related costs for additional accounting staff; and listing and transfer agent fees. The following table provides information on the amount of our selling, general and administrative expenses for each of these costs and the percentage of total revenues for each of these costs for the periods shown.

Miscellaneous income

Substantially all of our miscellaneous income was derived through the CCC Bioenergy Program, a government program established through the United States Department of Agriculture that provided cash payments for companies that generate increases in bioenergy production, such as ethanol, from previous production levels. We do not expect any further income attributable to this program.

Results of Operations

Three Months Ended March 31, 2006 Compared to Three Months Ended March 31, 2005

Total revenues

Total revenues for the first quarter of 2006 increased $9.8 million, or 54.4%, to $27.8 million from $18.0 million for the first quarter of 2005. The increase in total revenues was primarily the result of a 28.9% increase in the total gallons of ethanol sold, from 10.5 million gallons of ethanol in the first quarter of 2005 to 13.6 million gallons of ethanol in the first quarter of 2006, as well as increased ethanol prices in the 2006 quarter. The average price realized on our sales of ethanol for the first quarter of 2006 increased to $1.83 per gallon, or 21.2%, from $1.51 per gallon for the first quarter of 2005. Accordingly, sales of ethanol for the first quarter of 2006 increased $8.9 million, or 56.1%, to $24.8 million from $15.9 million for the first quarter of 2005. Total revenues from distillers grains for the first quarter of 2006 increased $0.9 million, or 41.7%, to $3.0 million from $2.1 million for the first quarter of 2005. We sold 40,724 tons of distillers grains in the first quarter of 2006, an increase of 9,456 tons, or 30.2%, from 31,268 tons of distillers grains in the first quarter of 2005. Prices per ton of distillers grains averaged $72.92 in the first quarter of 2006, compared to $67.04 in the first quarter of 2005.

Cost of goods sold and gross profit

Corn costs for the first quarter of 2006 increased $1.7 million, or 24.8%, to $8.5 million from $6.8 million for the first quarter of 2005. Corn represented 45.5% of our cost of goods sold for the first quarter of 2006, compared to 53.4% for the first quarter of 2005. Our net corn costs represented 35.2% of our net cost of goods sold for the first quarter of 2006, compared to 44.3% for the first quarter of 2005. Our average cost per bushel of corn decreased 3.7% in the first quarter of 2006 compared to the first quarter of 2005. We used 4.8 million bushels of corn in the first quarter of 2006, an increase of 1.1 million bushels, or 29.5%, from 3.7 million bushels purchased in the first quarter of 2005.

Natural gas costs for the first quarter of 2006 increased $1.9 million, or 92.0%, to $4.0 million from $2.1 million for the first quarter of 2005. Natural gas costs for the first quarter of 2006 represented 21.5% of our cost of goods sold, compared to 16.4% of our cost of goods sold for the first quarter of 2005. The increased cost of natural gas as a percentage of our cost of goods sold was primarily attributable to increased natural gas prices during the year. The average price for natural gas increased 53.2% from $6.74 to $10.32 per MMBTU in 2006, as a result of supply disruptions from the summer 2005 hurricanes and overall economic conditions. We purchased 389,488 MMBTU of natural gas in the first quarter of 2006, an increase of 78,748 MMBTU, or 25.3%, from 310,740 MMBTU in the first quarter of 2005.

Gross profit for the first quarter of 2006 increased $3.8 million, or 73.2%, to $9.1 million from $5.2 million for the first quarter of 2005.

Selling, general and administrative expenses

Selling, general and administrative expenses for the first quarter of 2006 decreased $0.9 million, or 33.5%, to $1.8 million from $2.6 million for the first quarter of 2005. The decrease was primarily the result of the writeoff of debt issuance costs in the first quarter of 2005, partially offset by increasing our management and administrative staff over the prior period in anticipation of the expansion of our business due to growth of our Iowa Falls plant and construction of our Fairbank plant.

Operating gain

Operating gain for the first quarter of 2006 increased $4.7 million, or 182.3%, to $7.3 million from $2.6 million for the first quarter of 2005. The increase was primarily the result of an increase in the average ethanol sales price.

Other income (expense)

Interest expense for the first quarter of 2006 increased $0.3 million, or 14.1%, to $2.4 million from $2.1 million for the first quarter of 2005. Interest income increased $0.5 million to $0.8 million for the first quarter of 2006 from $0.3 million for the first quarter of 2005. Miscellaneous income for the first quarter of 2006 decreased $0.4 million to $0.2 million from $0.6 million for the first quarter of 2005, primarily due to a reduction in receipts from the United States Department of Agriculture under the CCC Bioenergy Program for the first quarter of 2006.

We recorded a net gain from commodity option transactions of $0.9 million in the first quarter of 2006, compared to no gain or loss for the first quarter of 2005. See "—Summary of Critical Accounting Policies and Estimates—Derivative Instruments and Hedging Activities."

Year Ended December 31, 2005 Compared to Year Ended December 31, 2004

As noted above, our Iowa Falls plant did not commence operations until November 2004, and we were in the development stage for substantially all of 2004. As a result, changes in 2005 compared to

2004 of the dollar amounts, quantities and volumes are primarily attributable to the differing levels of operating activity.

Total revenues

Total revenues for 2005 increased $80.8 million to $89.1 million from $8.3 million for 2004. The increase in total revenues was primarily the result of an increase in the total gallons of ethanol that we sold, from 4.6 million gallons of ethanol in 2004 to 48.3 million gallons of ethanol in 2005, mainly because of the increased number of months of activity in 2005 compared to 2004. The average price realized on our sales of ethanol increased to $1.65 per gallon for 2005 from $1.63 per gallon for 2004 due to market conditions. Total revenues from ethanol for 2005 increased $71.9 million to $79.4 million from $7.5 million for 2004. Total revenues from distillers grains for 2005 increased $8.9 million to $9.7 million from $0.8 million for 2004. We sold 143,828 tons of distillers grains in 2005, an increase of 128,904 tons from 14,924 tons of distillers grains in 2004. Prices per ton of distillers grains averaged $67.41 in 2005, compared to $55.36 in 2004.

Cost of goods sold and gross profit

Corn costs for 2005 increased $29.8 million to $34.7 million from $4.9 million for 2004. Corn represented 51.6% of our cost of goods sold in 2005, compared to 62.5% in 2004. Our net corn costs represented 43.5% of our net cost of goods sold for 2005, compared to 58.0% for 2004. Our average cost per bushel of corn decreased 34.1% in 2005 compared to 2004. We purchased 17.2 million bushels of corn in 2005, an increase of 15.6 million bushels from 1.6 million bushels in 2004.

Natural gas costs for 2005 increased $10.8 million to $11.9 million from $1.1 million for 2004. Natural gas costs represented 17.7% of our cost of goods sold for 2005, compared to 13.7% of our cost of goods sold for 2004. The increased cost of natural gas as a percentage of our cost of goods sold was primarily attributable to increased natural gas prices during the year. The average price for natural gas increased 25.9% for 2005 from 2004, as a result of colder than average weather conditions and overall economic conditions. We purchased 1.4 million MMBTU of natural gas in 2005, an increase of 1.2 million MMBTU from 0.2 million MMBTU in 2004.

Gross profit for 2005 increased $21.4 million to $21.9 million from $0.5 million for 2004.

Selling, general and administrative expenses

Selling, general and administrative expenses for 2005 increased $5.2 million to $6.8 million from $1.5 million for 2004. The increase was primarily a result of a full year of operation of the Iowa Falls plant in 2005, compared to two months of operation in 2004, as well as an increase of our management and administrative staff over the prior period in anticipation of the expansion of our business due to expansion of our Iowa Falls plant and construction of our Fairbank plant.

Operating gain

Operating gain for 2005 was $15.1 million. We recorded an operating loss in 2004, during the start-up of our Iowa Falls plant.

Other income (expense)

Interest expense increased $14.2 million for 2005 to $14.9 million from $0.7 million for 2004. Interest income increased $3.2 million for 2005 to $3.3 million from $0.1 million for 2004. Miscellaneous income in 2005 was $5.0 million.

We recorded a net gain from commodity option transactions of $49,000 in 2005, compared to a loss of $0.6 million in 2004. See "—Summary of Critical Accounting Policies and Estimates—Derivative Instruments and Hedging Activities."

Liquidity and Capital Resources

Our principal sources of liquidity consist of cash and cash equivalents, restricted cash, cash provided by operations and available borrowings under our credit facilities. In addition to funding operations, our principal uses of cash have been, and are expected to be, the debt service requirements of our indebtedness, the construction of new facilities, capital expenditures and general corporate purposes. As a result of the Conversion, we will become subject to income tax.

We financed our operations for 2005 primarily through cash provided by financing activities. At December 31, 2005, we had total cash of $101.4 million compared to $3.8 million at December 31, 2004. Cash provided by operating activities was $25.9 million for 2005 compared to cash provided by operating activities of $2.0 million for 2004. The change in operating cash flow was primarily a result of including a full year's production in 2005.

Cash used in investing activities was $184.6 million for 2005 compared to $55.1 million for 2004. The increase primarily resulted from capital spending related to construction activities for the Iowa Falls expansion and the Fairbank plant construction.

Cash provided by financing activities was $179.5 million for 2005 compared to $56.9 million for 2004. The increase primarily resulted from the proceeds to us of $185.0 million from the 2005 senior secured term loan facility, partially offset by principal repayments on long-term debt of $24.2 million.

As of December 31, 2005, we had total liabilities of $267.2 million.

Our financial position and liquidity are, and will be, influenced by a variety of factors, including:

•: our ability to generate cash flows from operations;
•: the level of our outstanding indebtedness and the interest we are obligated to pay on this indebtedness; and
•: our capital expenditure requirements, which consist primarily of plant construction and the purchase of equipment.

The Transactions

The Transactions will have a significant impact on our liquidity and capital resources. In connection with the THL Transactions we will enter into new $650 million term loan facilities that will replace our existing $185 million term loan facility and $55.6 subordinated notes. We refer to our $650 million term loan facilities and our revolving credit facility together as the 2006 senior secured credit facilities. Also, as discussed in "—Summary of Critical Accounting Policies and Estimates—Income Taxes" below, following the Conversion we will become subject to paying entity level income taxes on our future profits and will be required to make payments under a tax receivables agreement. The 2006 senior secured credit facilities will result in higher debt service requirements than historically have been required and we will have tax obligations, including obligations under the tax receivables agreement, to which we have not historically been subject.

Upon completion of the Transactions, we will also have available a $50 million revolving credit facility and will have proceeds from this offering that will be held to fund in part our expansion plans and be available for general corporate purposes. As of December 31, 2005, we would have had total liabilities of $ and total cash of $ on a pro forma basis after giving effect to the Transactions.

We intend to fund our principal liquidity requirements through cash and cash equivalents, cash provided by operations and borrowings under our new revolving credit facility. We believe our sources of liquidity will be sufficient to meet the cash requirements of our operations for at least the next 12 months.

To finance any material acquisitions or joint ventures, expand our operations or make additional capital expenditures, however, we may need to seek additional sources of funding, including from the issuance of additional equity or debt. Acquisitions or further expansion of our operations could cause our indebtedness, and our ratio of debt to equity, to increase. Our ability to access these sources of capital will be restricted by the terms of the new credit agreement governing our 2006 senior secured credit facilities.

2005 Senior Secured Term Loan Facility

On February 24, 2005, we entered into a credit agreement establishing a $185.0 million senior secured term loan facility, the proceeds of which were used to finance the expansion of the Iowa Falls plant and construction of the Fairbank plant, to pay down an existing bank loan of $24.2 million associated with the Iowa Falls plant, to fund a 12-month debt service reserve, to pay fees and expenses related to the senior secured term loan facility and the credit agreement and to fund other transaction expenses. The term loan matures on January 31, 2012 and requires quarterly principal payments starting July 31, 2006.

Our obligations under the credit agreement are secured by substantially all of our assets and contains prepayment penalties. We are obligated to apply a portion of our excess cash flow to principal payments in order to meet the schedule of maximum outstanding debt levels. The term loan facility bears interest at a six-month LIBOR rate plus 2.875%. As of December 31, 2005, there was an outstanding balance of $185.0 million under the credit agreement.

In connection with the THL Transactions, we will repay and retire the 2005 credit agreement and the $185.0 million senior secured term loan facility.

Capital Expenditures

Not including expenditures related to new construction and acquisition of additional capacity, we expect to make capital expenditures of approximately $1.2 million and $1.7 million in 2006 and 2007, respectively, related to our existing facilities. Expenditures related to our growth strategy are expected to be funded with a portion of the proceeds at this offering, together with our operating cash flow.

Quantitative and Qualitative Disclosures about Market Risk

Market Risk

We consider market risk to be the potential loss arising from adverse changes in market rates and prices. We are subject to significant market risk with respect to the price of ethanol, our principal product, and the price and availability of corn, the principal commodity used in our ethanol production process. In general, ethanol prices are influenced by the supply and demand for gasoline, the availability of substitutes and the effect of laws and regulations. Higher corn costs result in lower profit margins and, therefore, represent unfavorable market conditions. We have not been able to pass along increased corn costs to our ethanol customers. The availability and price of corn are subject to wide fluctuations due to unpredictable factors such as weather conditions during the corn growing season, carry-over from the previous crop year and current crop year yield, government policies with respect to agriculture, and international supply and demand. Corn costs represented approximately 51.6% of our total cost of goods sold for 2005. Over the ten-year period from 1996 through 2005, corn prices (based on the CBOT daily futures data) have ranged from a low of $1.75 per bushel in 2000 to a high of $5.48 per bushel in 1996, with prices averaging $2.47 per bushel during this period. At December 30, 2005, the CBOT price per bushel of corn was $2.16.

We are also subject to market risk with respect to our supply of natural gas that is consumed in the ethanol production process. Natural gas prices and availability are affected by weather conditions and overall economic conditions. Natural gas represented 17.7% of our cost of goods sold for 2005. The price of natural gas prices over the six-year period from December 31, 1999 through December 28, 2005, based on the NYMEX daily futures data, has ranged from a low of $2.34 per MMBTU in 2000 to a high of $18.66 per MMBTU in 2003, averaging $5.25 per MMBTU during this period. At December 30, 2005, the NYMEX price of natural gas was $11.23 per MMBTU.

To reduce price risk caused by market fluctuations in the commodities we use and sell, as well as interest rates, we may enter into exchange-traded commodities futures, options and interest rate swaps. These hedging arrangements also expose us to the risk of financial loss in situations where the other party to the hedging contract defaults on its obligations under the contract or there is a change in the expected differential between the underlying price in the hedging agreement and the actual price of the commodities.

Periodically, we use exchange traded options or futures contracts to reduce our exposure to various commodity market risks. We have elected not to adopt hedge accounting for any futures contracts that may otherwise qualify for hedge accounting under Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative Instruments and Certain Hedging Activities, as amended (SFAS 133). Accordingly, any realized or unrealized gain or loss related to these derivative financial instruments is recorded as gain or loss on the income statement. We realized a net gain of $48,866 on commodity option transactions for the year ended December 31, 2005. In addition, in 2005 we entered into an interest rate swap to minimize the impact of interest rate changes, which also is not accounted for under hedge accounting. All gains or losses therefore are included in interest expense on the income statement.

As part of normal business operations we enter into corn purchase contracts with local farmers for bushels of corn to be used in the production of ethanol. We have marked these contracts to market as required under SFAS 133 with the change in market value reflected in cost of goods sold. As of December 31, 2005, the contracts were recorded as a liability of $585,000. Also in the normal course of business operations, we enter into sales contracts for the future delivery of ethanol and distillers grains. We have concluded that these contracts do not meet the definition of a derivative under SFAS 133 as there is no ability for net settlement. These contracts are shown as commitments in note 6 to our consolidated financial statements for the year ended December 31, 2005.

We have prepared a sensitivity analysis to estimate our exposure to market risk with respect to our corn and natural gas requirements, ethanol and distillers grains contracts and the related exchange-traded contracts for 2005. Market risk is estimated as the potential loss in fair value, resulting from a hypothetical 10.0% adverse change in the fair value of our corn and natural gas requirements and ethanol and distillers grains contracts (based on average prices for 2005). The results of this analysis, which may differ from actual results, are as follows:

	2005 Volume	Units	Hypothetical Adverse Change in Price	Change in annual gross margin
	(in millions)			($ in millions)
Corn	17.2	bushels	10.0%	3.5
Ethanol	48.3	gallons	10.0%	7.9
Distillers Grains	0.144	tons	10.0%	1.0
Natural Gas	1.4	MMBTU	10.0%	1.2

We will be subject to interest rate risk in connection with our 2006 senior secured credit facilities. Borrowings under the credit agreement will bear interest at LIBOR plus the applicable margin, which is %. In connection with the THL Transaction, we expect to draw $650.0 million under the 2006 senior secured term loan. As a result, a hypothetical increase in interest rates of 100 basis points would have a material effect on our annual interest expense.

In 2005, we entered into an interest rate swap to minimize the impact of interest rate changes, which also is not accounted for under hedge accounting, and therefore all gains or losses are included in interest expense on the income statement. We fixed the interest rate on a notional amount of variable debt at 4.205%. Under the terms of the interest rate swap, we receive variable interest rate payments and make fixed interest rate payments, thereby creating the equivalent of fixed-rate debt on that portion of the debt. Generally, the fair value to us of fixed interest rate debt will decrease as interest rates fall and increase as interest rates rise. Starting in 2007, the notional amount will be reduced quarterly though the end of the swap on July 31, 2010. The swap transaction resulted in an asset of $2.1 million at December 31, 2005 based on our favorable position of the locked-in fixed rate compared to variable rates at December 31, 2005. The swap transaction will be terminated upon the closing of the THL Transactions.

Hedging and Other Price Mitigation Strategies

We seek to mitigate our exposure to commodity price fluctuations by purchasing forward a portion of our corn and natural gas requirements on a fixed price basis and by purchasing corn futures contracts. We attempt to match the volume and timing of forward corn purchases and futures with our ethanol sales contracts. To mitigate ethanol and distillers grain price risk, we sell a portion of our production forward under fixed price contracts. We believe our strategy of managing exposure to commodity price fluctuations will reduce somewhat the volatility of our results by creating a fixed crush spread for a portion of our production, but will also reduce our ability to benefit from favorable changes in prices.

A substantial number of our ethanol sales contracts are based on contracting periods that range from six to 12 months. These contracts are typically entered into months before the contract commences. Our raw materials purchases are forecasted to take into account our expected production of ethanol and distillers grains.

As of December 31, 2005, approximately 64% and 16%, respectively, of our estimated ethanol and distillers grains production for 2006 was subject to fixed-price contracts, and we had contracted forward on a fixed-price basis the following quantities of corn and natural gas, which represent the indicated percentages of our estimated requirements for these inputs for 2006:

		Year Ending December 31, 2006
Corn (bushels)		5,072,956
Natural gas (MMBTU)		236,000

Summary of Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements included in this prospectus, which have been prepared in conformity with GAAP. Note 1 to our consolidated financial statements for 2003, 2004 and 2005 included elsewhere in this prospectus contains a summary of our significant accounting policies, many of which require the use of estimates and assumptions. Accounting estimates are an integral part of the preparation of financial statements and are based upon management's current judgment. The process used by management in making judgments encompasses its knowledge and experience about past and current events and certain assumptions regarding future events. The judgments and estimates reflect the effects of matters that are inherently uncertain and that affect the carrying value of our assets and liabilities. We believe that of our significant accounting policies, the following are noteworthy because changes in these estimates or assumptions could materially affect our financial position and results of operations.

Hawkeye Holdings, LLC

Recoverability of Long-Lived Assets

Hawkeye Holdings, LLC has a substantial investment in property, plant and equipment. We record property, plant and equipment at cost. We recognize the cost of depreciable assets in operations over the estimated useful life of the assets, and we evaluate the recoverability of these assets whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable.

The assessment of the recoverability of long-lived assets reflects management's assumptions and estimates. Factors that management must assess in evaluating the recoverability of long-lived assets include whether or not circumstances require a formal evaluation and, if an impairment test is required, estimates of future sales volume, prices, inflation, discount rates and capital spending, among others. Significant management judgment is involved in assessing existing circumstances and estimating these factors, and they include inherent uncertainties. The measurement of the recoverability of long-lived assets is dependent upon the accuracy of the assumptions used in making these estimates and how the estimates compare to the eventual future operating performance of the enterprise. Certain of the operating assumptions are particularly sensitive to the developing nature of the ethanol business.

We have not recognized any impairment of our long-lived assets during the period from our inception through March 31, 2006.

Environmental Liabilities and Asset Retirement Obligation

We also record accrued liabilities for various environmental matters when they are considered probable and estimable. The processes used to identify and estimate any such liabilities are complex. Accruals for environmental matters are based on estimates for the cost of remediation. In accordance with Statement of Financial Accounting Standards (SFAS) No. 5, Accounting for Contingencies, we are required to assess the likelihood of material adverse outcomes as well as potential ranges or probability of losses. We determine the amount of accruals required for contingencies, if any, after carefully analyzing each individual matter. The required accruals may change due to new developments in each matter. Actual costs to be incurred in future periods may vary from the estimates. Due to the inherent uncertainties related to environmental exposures, a liability could be required to be recorded if sites are identified to need environmental remediation, the scope of required remediation is increased, or our proportionate share of responsibility for a site is increased.

Revenue Recognition and Customer Concentration

Revenues are recorded when all of the following criteria are met: persuasive evidence of an arrangement exists, product has been shipped FOB shipping point, risk of loss has passed to the buyer, the price is fixed and determinable, and collectibility is reasonably assured. Shipping costs billed to customers are included gross in revenue and cost of sales. We have two customers, one of which accounts for all of our ethanol sales and the other of which accounts for all of our sales of distillers grains.

Derivative Instruments and Hedging Activities

We account for derivatives and hedging activities in accordance with SFAS No. 133, Accounting for Derivative Instruments and Certain Hedging Activities, as amended, which requires that all derivative instruments be recorded on the balance sheet at their respective fair values.

Periodically, we use exchange traded options or futures contracts to reduce our exposure to various commodity market risks.

In addition, we use variable-rate debt to finance our operations, which exposes us to variability in interest payments due to changes in interest rates. Management believes that it is prudent to limit the variability of a portion of our interest payments. To meet this objective, we enter into interest rate swap agreements to manage fluctuations in cash flows resulting from interest rate risk.

The valuation of these financial instruments involves estimates and judgments and can be complex, as does the accounting and reporting of such instruments.

Hawkeye Holdings Inc.

Following the completion of the Transactions described in this prospectus, we expect to identify accounting for income taxes and accounting for share-based payments as critical accounting policies. However, these matters have not had any significant impact on the historical consolidated financial statements of Hawkeye Holdings, L.L.C. included in this prospectus.

Seasonality

Our operating results are influenced by seasonal fluctuations in the price of our primary operating inputs, corn and natural gas, and the price of our primary product, ethanol. The spot price of corn tends to rise during the Spring planting season in May and June and tends to decrease during the Fall harvest in October and November. The price for natural gas, however, tends to move opposite that of corn and tends to be lower in the Spring and Summer and higher in the Fall and Winter. In addition, our ethanol prices are substantially correlated with the price of unleaded gasoline, which tends to rise

during each of the Summer and Winter. As a result of seasonal fluctuations, we believe comparisons of operating measures between consecutive quarters may be not as meaningful as comparisons between longer reporting periods.

Inflation

Since our inception, inflation has not significantly affected our operating results. Costs for construction, taxes, repairs, maintenance and insurance are all subject to inflationary pressures, however, and could affect our ability to maintain our facilities adequately, build new ethanol production facilities and expand our existing facilities.

Recently Issued Accounting Standards

In December 2004, the Financial Accounting Standards Board—FASB—issued Statement No. 151, Inventory Costs (SFAS 151), which clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). Under SFAS 151, such items will be recognized as current-period charges. In addition, SFAS 151 requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS 151 will be effective for us for inventory costs incurred on or after January 1, 2006. The adoption of SFAS 151 will not have a significant effect on our financial statements.

In May 2005, FASB issued Statement No. 154, Accounting Changes and Error Corrections (SFAS 154). SFAS 154 establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transition requirements specific to a newly adopted accounting principle. SFAS 154 will be effective for us for all accounting changes and any error corrections occurring after January 1, 2006.

In March 2005, the FASB issued FASB Interpretation No. 47 Accounting for Conditional Asset Retirement Obligations (FIN 47) which requires conditional asset retirement obligations to be recognized if a legal obligation exists to perform asset retirement activities and a reasonable estimate of the fair value of the obligation can be made. FIN 47 also provides guidance as to when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. We adopted the provisions of FIN 47 on December 31, 2005. No conditional asset retirement obligations were recognized and, accordingly, the adoption of FIN 47 had no effect on our financial statements.

We do not expect that the adoption of other recent accounting pronouncements will have a material impact on our financial statements.

INDUSTRY OUTLOOK

General

Ethanol is a clean-burning, high-octane fuel that is produced from renewable sources. In the United States, ethanol is produced primarily from corn and is used as a vehicle fuel and as a gasoline fuel additive to increase gasoline's octane rating and to comply with air emissions regulations by reducing emissions of carbon monoxide and nitrous oxide. Ethanol currently comprises 3% of the total U.S. gasoline fuel supply and is blended into one-third of the gasoline consumed in the United States. All automobiles in the United States can operate with a fuel mix that is 90% gasoline and 10% ethanol, also referred to as E10 fuel. E10 is approved for use under the warranties of all major motor vehicle manufacturers and often is recommended as a result of ethanol's clean-burning characteristics. Ethanol comprises up to 85% of E85 fuel. Although E85 currently represents a relatively small portion of the U.S. gasoline supply, approximately six million vehicles in the United States today are Flexible Fuel Vehicles, or FFVs, capable of using E85 fuel.

The ethanol industry has grown significantly over the last few years, expanding production capacity at a compound annual growth rate of approximately 20% from 2000 to 2005, according to the RFA. We believe the ethanol market will continue to grow as a result of its favorable production economics relative to gasoline, a shortage of domestic petroleum refining capacity, federally-mandated renewable fuel usage, favorable tax treatment, ethanol's clean-burning characteristics and geopolitical and environmental concerns with petroleum-based fuels.

Reasons for substantial growth prospects in the ethanol market include:

Favorable production economics

We believe that the costs ethanol producers incur in producing a gallon of ethanol currently are significantly lower than the costs refiners incur in producing a gallon of petroleum-based gasoline.

Favorable tax treatment

One factor contributing to ethanol's attractive economics is the availability of a partial exemption from the federal excise tax on motor fuels for ethanol blended fuels. We believe ethanol's favorable production economics, further enhanced by the blenders' tax credit, will enable ethanol to comprise an increasingly larger portion of the U.S. fuel supply. This exemption can be captured by refiners or passed on to consumers. Currently, blends of 90% gasoline and 10% ethanol are exempt from $0.051 of the $0.184 federal excise tax on motor fuels, which equates to $0.51 per gallon of ethanol. Due to this credit, ethanol historically has traded at a per gallon premium to gasoline. Prorated exemptions are available for commonly used blending proportions below 10%.

Inadequate supply to meet demand

We believe that the ethanol industry lacks sufficient capacity to meet current and anticipated demand. With the withdrawal of MTBE from the nation's gasoline supply, we believe that the demand for oxygenates, including ethanol, will exceed six billion gallons in the next few years.

Blending benefits

Ethanol has an octane rating of 113, and is added to the blend stock to raise the octane level from gasoline's base level of approximately 84 to the typical octane ranges sold by gasoline retailers today of 87 to 93 octane—regular unleaded to super high-octane. Fuel sources with higher

octane typically have been sold at a high price per gallon relative to lower octane fuel sources due to the benefits associated with a higher octane content.

Expansion of gasoline supply

By blending ethanol into their gasoline, refiners can expand the volume of fuel available to be sold, and therefore can produce more fuel from a barrel of oil and expand their ability to meet consumer demand, especially during times when refinery capacity and octane sources are limited.

Renewable Fuels Standard

In August 2005, President Bush signed the Energy Policy Act, that established the renewable fuel standard—RFS. The RFS mandates minimum annual use of 7.5 billion gallons per year of renewable fuels in the U.S. fuel supply by 2012. We believe that the RFS will increase demand for ethanol. The RFS requires motor fuels sold in the United States to contain in the aggregate the following minimum volumes of renewable fuels in future years:

Year		Renewable Fuel Usage
		(in billions of gallons)
2006		4.0
2007		4.7
2008		5.4
2009		6.1
2010		6.8
2011		7.4
2012		7.5

The Energy Policy Act also proposed a credit trading program to facilitate meeting the industry-wide renewable fuels requirements. The Environmental Protection Agency is expected to establish the rule for issuing and trading the credits by late 2006 or early 2007.

Environmental benefits

Ethanol, as an oxygenate, reduces tailpipe emissions when added to gasoline, resulting in improved air quality. The additional oxygen in the ethanol results in a more complete combustion of the fuel in the engine cylinder, resulting in reduced carbon monoxide and nitrogen oxides emissions. Federal programs that mandated the use of oxygenated gasoline in areas with high levels of air pollution spurred widespread use of ethanol in the United States.

Ethanol as a gasoline substitute

Automakers in the United States have been accelerating work on their E85 FFV programs. Ethanol has the potential to reduce the consumption of gasoline in the U.S. economy due to its characteristics as a high-octane fuel made from renewable sources that can provide flexibility to blenders and refiners. We believe that in the future, a significant number of motorists will choose FFVs due to their lower greenhouse gas emissions, flexibility, and performance characteristics. Widespread adoption of FFVs could significantly boost ethanol demand.

Replacement of MTBE

Because of their blend characteristics, availability and cost, ethanol and MTBE were the two primary additives used to meet the Clean Air Act's oxygenate requirements. Because MTBE could be produced and blended with gasoline at the refinery and transported through a pipeline, it was initially the preferred oxygenate ingredient used by the petroleum industry in most reformulated

gasoline. Before 2003, ethanol was used primarily as a fuel extender and octane enhancer, predominantly in the Midwest.

In recent years, as a result of health and environmental concerns resulting from the discovery of the presence of MTBE, a suspected carcinogen, in ground water supplies, 25 states, representing more than half of the MTBE consumed in the U.S., including California, New York and Connecticut, have banned or significantly limited the use of MTBE. Product liability concerns regarding MTBE increased following passage of the Energy Policy Act, which did not contain limitations on product liability claims relating to MTBE use. As a result, refiners generally have phased-out MTBE nationwide, creating additional demand for ethanol outside of the Midwest and California. As MTBE is replaced, ethanol is positioned to be the most likely substitute for MTBE because of its favorable production economics, high octane rating and clean burning characteristics.

Geopolitical concerns

The United States is dependent on foreign oil. Political unrest and attacks on oil infrastructure in the major oil-producing nations, particularly in the Middle East, have periodically disrupted the flow of oil. Fears of terrorist attacks have added a "risk premium" to world oil prices. At the same time, developing nations such as China and India have increased their demand for oil. As a result, world oil prices ranged from $50 to $70 per barrel at times during 2005 and have averaged above $60 a barrel during 2006, reaching record highs above $75 a barrel during April 2006. As a domestic, renewable source of energy, ethanol can reduce the United States' dependence on foreign oil by increasing the amount of fuel that can be consumed for each barrel of imported crude oil.

Supply of Ethanol

The primary feedstock for ethanol production in the United States is corn. Proximity to corn supplies is a crucial factor in the economics of ethanol plants, as transporting corn is much more expensive than transporting finished ethanol product. As such, the ethanol industry is geographically concentrated in the Midwest based on the proximity to the highest concentration of corn supply. Over 75% of the ethanol produced in the United States comes from five Midwestern states, with the corn-rich state of Iowa alone possessing nearly 27% of the total United States ethanol capacity. In addition to corn, the ethanol production process requires natural gas, or in some cases, coal to power the facility and dry distillers grains.

Despite the geographic concentration, production in the ethanol industry remains fragmented. While domestic ethanol production increased from 1.7 billion gallons in 1997 to 4.0 billion gallons in 2005 according to the RFA, the top four producers accounted for approximately 41% of the industry's total estimated production capacity as of February 2005, according to the National Farmers Union. More than 50 smaller producers and farmer-owned cooperatives, most with production of 50 MMGPY or less, generate the remaining production. Since a typical ethanol facility can be constructed in approximately 18 months from groundbreaking to operation, the industry is able to forecast capacity additions for up to 18 months in the future. As of May 2006, the RFA estimates 41 new or existing ethanol facilities with capacity of an aggregate of an additional 2.0 billion gallons per year were under construction.

Ethanol is typically either produced by a dry-milling or wet-milling process. Although the two processes feature numerous technical differences, the primary operating trade-off of the wet-milling process is a higher co-product yield in exchange for a lower ethanol yield. Dry-milling ethanol production facilities constitute the substantial majority of new ethanol production facilities constructed in the past five years because of the increased efficiencies and lower capital costs of dry-milling technology. Dry-mill ethanol facilities typically produce between five and 50 MMGPY, with newer

dry-mill facilities producing over 100 MMGPY and enjoying economies of scale in both construction and operating costs per gallon. According to the RFA, 79% of the ethanol production capacity is generated from dry-mill facilities, with only 21% coming from wet-mill facilities.

With the largest proportion of ethanol production, the Midwest is one of the largest consumers of ethanol fuel in the United States. After California, which is the largest consumer of ethanol, Midwestern states such as Minnesota, Illinois and Ohio are the largest consumers of ethanol. Additionally, the state MTBE bans in Connecticut and New York have increased the ethanol consumption in these states. Various states have mandated ethanol use, including Minnesota, Illinois, Ohio and California. These state policies require the use of ethanol above and beyond what is required by federal regulations, including the RFS.

BUSINESS

Business Overview

For the year ended December 31, 2005, we generated revenue of $89.1 million, net income of $8.6 million and EBITDA of $26.1 million, and we sold 48.3 million gallons of ethanol at an average price per gallon of $1.65. For the three months ended March 31, 2006, we generated revenue of $27.8 million, net income of $6.8 million and EBITDA of $9.6 million, and we sold 13.6 million gallons of ethanol at an average price per gallon of $1.83. We have sold forward 32% of our estimated ethanol production for the 12-month period ending June 30, 2007, at an average price of $2.01 per gallon. For a reconciliation of net income to EBITDA, see footnote 4 under "Selected Historical and Pro Forma Consolidated Financial Data".

Competitive Strengths

We believe that we have the following competitive strengths:

State-of-the-art production technology and operational scale. We have approximately 205 million gallons of annual production capacity at our two state-of-the-art plants, which were designed by ICM, Inc., and built by Fagen, Inc. As a result of the ICM process technology, our plants have one of the highest corn-to-ethanol conversion yields in the ethanol industry today. In addition, we believe our plants have higher throughput, lower production costs and higher operating efficiency than smaller and older plants, which make up the vast majority of industry capacity. The average size of an ethanol production facility in the U.S. is approximately 46 MMGPY, according to the RFA. In addition, we believe that our plants operate at among the lowest ratios of plant-level employees per gallon of annual production capacity in our industry.

Optimal locations for low cost corn supply. The location of our plants in Iowa, in some of the highest yielding areas of the nation's "Corn Belt," gives us ready access to corn at favorable prices. We purchase a substantial portion of our corn supply directly from local farmers, which we believe is less costly than purchasing corn from cooperatives or shipping across longer distances. The eight year historical average discount to the CBOT for corn is $0.32 per bushel in Iowa Falls and $0.26 per bushel in Fairbank.

Advantageous logistics infrastructure and capabilities. Due to the large scale of our facilities, our facilities' access to national rail networks and the ample rail siding at our facilities, we plan to offer to ship entire unit trains—75 or more rail cars at a time—to our ethanol markets, a volume that would allow us to achieve favorable rail rates per gallon with a shorter delivery time. The relatively rapid delivery time afforded by access to national rail networks also allows us to use

leased rail cars more productively, effectively increasing the annual volume each rail car can transport and lowering our per-gallon rail car leasing expense.

Well-positioned to capitalize on industry growth. We have proven our ability to find and secure optimal plant locations and execute on the construction, completion and operation of two of the largest ethanol facilities built in recent years. As the industry expands to satisfy the expected substantial increase in ethanol demand, we are well-positioned with our current expansion plans, which include breaking ground on a new plant in each of 2006 and 2007, to take advantage of this growth.

Experienced management. Our management team has extensive experience in ethanol and a variety of agricultural businesses, and has successfully overseen construction of the our Iowa Falls and Fairbank production plants. We believe our team's long history in the local Iowa markets helps us procure a consistent supply of low-cost corn and foster a source of demand for our distillers grains.

Business Strategy

Maintain focus on cost efficiency and technological advantages. Since our inception, we have striven to operate as a low-cost producer utilizing the latest production technology with access to the lowest cost inputs. As we grow, we will continue to focus on these cost efficiencies and technologies by locating plants in low-cost corn regions and exploring the latest technology to achieve the highest production throughput at the lowest cost.

Expand production capacity through greenfield development. We seek to capitalize on the rapidly growing demand for ethanol by using our project development and operating expertise to add additional production capacity as the industry grows. We have secured the right to acquire four well-located sites in Iowa and we intend to break ground on one plant in 2006 and a second plant in 2007 for an additional 200 MMGPY of production capacity, which will bring our total production capacity to over 400 MMGPY. In addition, we will evaluate opportunities to acquire additional ethanol producers which we can use to leverage our operating expertise.

Capitalize on ethanol marketing advantages. We believe our production scale, our access to national rail networks and destination markets and our plan to offer to ship unit trains provide us with a competitive advantage when marketing our ethanol and result in favorable prices to us. Because of these advantages we have opted not to be part of a "pooled" marketing program in which those benefits would be shared with other producers in the "pool" that do not enjoy similar competitive advantages. See "Risk Factors—Risks Relating to Our Business and Industry—Our operating results may suffer if Eco-Energy Inc. (EEI) does not perform its obligations under existing arrangements or if we are unable to achieve results comparable to those achieved by selling ethanol through EEI in the event we begin marketing and selling our ethanol directly to our customers."

Employ strategic risk mitigation techniques. We analyze and employ risk mitigation techniques in order to limit our exposure to commodity price fluctuations. These techniques include attempting to match the contracted sales of ethanol with proportionate purchases of corn supply requirements to lock in crush spreads, futures and options positions on the CBOT corn market and forward purchases of natural gas. See "Risk factors—Risks Relating to our Business and Industry—Our results may be adversely affected by hedging transactions and other strategies."

Maintain flexibility to optimize production technologies. We review technological developments that might result in more efficient methods of ethanol production. We believe that our facilities will be able to accommodate modifications to utilize different feedstocks or production technologies that may become available in the future.

Ethanol Production Process

Our plants produce ethanol by processing corn with technology developed by ICM. A bushel of corn yields approximately 2.8 gallons of ethanol. Our dry-mill process of using corn to produce ethanol and co-products is illustrated in the following chart and described below.

Step One: Grain Receiving, Storing and Milling

We receive corn by rail and by truck, at which point we inspect, weigh and unload the corn in a receiving building and then transfer it to storage bins. On the grain receiving system, a dust collection system limits particulate emissions. Truck scales and a rail car scale weigh delivered corn. Corn unloading and storage systems include independent unloading legs and concrete and steel storage bins. From its storage location, corn is conveyed to scalpers to remove debris before it is transferred to hammermills or grinders where it is ground into a flour, or "meal."

Step Two: Conversion and Liquefaction, Fermentation and Evaporation Systems

The meal is conveyed into slurry tanks for enzymatic processing. The meal is mixed with water and enzymes and heated to break the ground grain into a fine slurry. The slurry is routed through pressure vessels and steam flashed in a flash vessel. This liquefied meal, now called "mash," reaches a temperature of approximately 200°F, which reduces bacterial build-up. The sterilized mash is then pumped to a liquefaction tank where additional enzymes are added. This cooked mash continues through liquefaction tanks and is pumped into one of the fermenters, where propagated yeast is added, to begin a batch fermentation process.

The fermentation process converts the cooked mash into carbon dioxide and beer, which contains ethanol as well as all the solids from the original feedstock. We employ the batch fermentation process in which the mash is kept in one fermentation tank for approximately two days. Circulation through external plate and frame heat exchangers, designed for high solids content and easy cleaning, keeps the mash at the proper temperature.

Step Three: Distillation and Molecular Sieve

After batch fermentation is complete, beer is pumped to the beer well and then to the distillation column to vaporize and separate the alcohol from the mash. The distillation results in a 96%, or 190-proof, alcohol. This alcohol is then transported through a rectifier column, a side stripper and a molecular sieve system where it is dehydrated to produce 200-proof anhydrous ethanol. The 200-proof alcohol and up to 5% denaturant constitute ethanol ready for sale.

Step Four: Liquid—Solid Separation System

The residue corn mash from the distillation stripper, called stillage, is pumped into one of several decanter type centrifuges for dewatering. The water, or thin stillage, is then pumped from the centrifuges back to mashing as backset or to an evaporator where it is dried into a thick syrup. The solids that exit the centrifuges, known as "wet cake," are conveyed to the wet cake storage pad or the gas-fired rotary dryer for removal of residual water. Syrup is added to the wet cake as it enters the dryer, where moisture is removed. The end result of the process is the production of dried distillers grains with solubles, or DDGS.

Step Five: Product Storage

Final storage tanks hold the denatured ethanol product prior to being transferred to loading facilities for truck and rail car transportation. Each of our plants has one 190-proof storage tank and one 200-proof storage tank. Our Iowa Falls plant has two 750,000 gallon final storage tanks with another two 750,000 gallon final storage tanks to be be added in the fourth quarter of 2006. Our Fairbank plant has two 1,500,000 gallon final storage tanks. These final storage tanks will accommodate ten days of storage per plant.

Co-Products of Ethanol Production

Our ethanol production facilities produce distillers grains as a co-product that is generated after the grains have been fermented by yeast. In the fermentation process, nearly all of the starch in the grain is converted to ethanol and carbon dioxide, while the remaining nutrients (proteins, fats, minerals and vitamins) undergo a three-fold concentration to yield modified distillers grains, or MDG, or, after further drying, dried distillers grains, or DDG. Addition of soluble syrup creates modified distillers grains with solubles, or MDGS. Each bushel of corn yields approximately 17 pounds of distillers grains in a dry mill process. Distillers grains are an economical partial replacement for corn, soybean and dicalcium phosphate in livestock and poultry feeds. Our distillers grains are marketed under the name Hawkeye Gold. Livestock owners buy large volumes of Hawkeye Gold distillers grain to enable the shipment of entire units trains with consistent quality product.

Distillers grains are derived from corn and contain a nutrient profile that has been proven to have beneficial properties for the diets of dairy and beef cattle, poultry and swine. The high digestibility and net energy content of DDGS and MDGS, compared to other feed ingredients such as soybean meal, canola meal and brewers spent grains, as well as their high fat content, results in greater milk production by dairy cattle. For beef cattle, the improved rumen health, energy effect of the fiber and palatability has been shown in feedlot studies to result in faster and more efficient weight gains.

MDGS are similar to DDGS but with a 50% moisture content rather than a 12% moisture content for DDGS. DDGS have a prolonged shelf life and reduce transportation expense, while MDGS are cheaper to produce as they spend less time in the drying process. We sell MDGS to local farmers, while DDGS are shipped longer distances by truck or rail. Most of our distillers grains sales are in the DDGS form.

Carbon dioxide, or CO₂, is also a by-product of our dry-mill ethanol production process. While CO₂ produced is typically of sufficient quality to be collected and sold, we do not currently market our CO₂. Currently, we scrub the CO₂ during the production process and release it to the atmosphere. In the future, we may explore the possibility of marketing CO₂.

Corn Procurement

Our operations require approximately 75 million bushels of corn per year in order to produce the 205 MMGPY of expected ethanol output. We source our corn supply both directly from Iowa farmers who transport the bushels directly to our production facilities and from local dealers. We publish a corn bid on our website that local farmers and cooperative dealers utilize to facilitate the corn supply transactions.

Each corn purchase at our Iowa Falls plant is negotiated on a separate contract which identifies the number of bushels, price and delivery period. The price always includes delivery to the plant, making transportation costs the seller's responsibility. Delivery terms are stated for delivery in a particular month, then the plant coordinates the specific delivery dates with the various sellers. Payment for the corn is required to be made within one day of the seller's request for payment, which is typically when the seller has completed delivery on a particular contract. Corn purchases at our Fairbank plant are negotiated on our behalf by Innovative Ag Services, with whom we contract our corn procurement requirements. Terms for corn sales to our Fairbank plant are on substantially similar terms as those we obtain for our Iowa Falls plant.

Ethanol Sales Logistics

Finished ethanol product is stored in the ethanol storage tanks at the plant sites. As empty rail cars arrive at the sites, they are loaded and generate a bill of lading. Our ethanol marketer, EEI, informs us as to which contracts the bills of lading apply. We then release the cars to the railroad, which schedules them for pickup. The EEI contract has a weekly cutoff, under which ethanol that is loaded by Sunday of each week is paid for the following Thursday, whether it has left our facility or not. Title passes to EEI at the time the ethanol is loaded into a rail car or truck.

Through a long-term lease agreement, we have access to over 500 rail cars for our exclusive use for at least the next five years. We believe that this dedicated rail supply provides us with a logistical advantage over other ethanol producers by allowing us to deliver ethanol to the highest bidders in a timely manner. In addition, we own a 63.5% interest in the D&W Railroad LLC, which owns the 52.0-mile spur from our Fairbank plant to the Iowa Northern line. Under our agreement with the co-owner, we are obligated to pay our proportionate share of maintenance and capital expenditures. Iowa Northern has contracted to perform maintenance and upkeep on the D&W track.

Marketing Arrangements

Ethanol marketing

Our ethanol currently is sold by our third party marketer, EEI. EEI has established relationships with many of the leading end-users of ethanol products such as major oil companies and refiners, as well as independent jobbers, storage companies and transportation companies. For typical ethanol producers that sell through marketers, ethanol sold to refiners or blenders is "pooled" into a cooperative system whereby the producers receive the average price of the ethanol sold for all producers in the marketing group, regardless of the actual price received if they had made a direct transaction with the blender. EEI does not pool our sales volume with other producers and sells directly to the refiners and blenders.

In the future, we may determine that our business is large enough for us to market ethanol directly to customers, giving us the benefits of direct customer contact and control over contract negotiations. In connection with the marketing and selling of our own ethanol, we would need to establish our own marketing, distribution, transportation and storage infrastructure, which would involve obtaining sufficient numbers of railcars and storage depots near our customers and at other strategic locations to ensure efficient delivery of our ethanol. We also would need to hire or outsource a marketing and sales force and logistical and other operational personnel to properly staff our distribution activities. In addition, our management would need to devote a larger portion of their time to the management of sales, marketing and distribution activities.

Distillers grains marketing

Our dried distillers grains are sold through marketing agreements with UBE Ingredients. In addition to UBE, we employ on-site merchandisers to develop relationships with local farmers to obtain higher prices for our products. Our DDGS is primarily marketed nationally to agricultural customers for use as animal feed. Our MDGS is sold to local agricultural customers for use as animal feed. We sell more DDGS due to limited markets for MDGS, which is not transported long distances due to high freight costs.

Our two plant managers are employees of United Bio Energy, LLC.

Our corporate headquarters are located at our Iowa Falls plant.

All of our property, including the Iowa Falls and Fairbank plants, is subject to a first-priority lien in favor of an affiliate of Credit Suisse Securities (USA) LLC pursuant to the senior secured term loan facility and Credit Agreement. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" and note 2 to our audited consolidated financial statements included elsewhere in this prospectus.

Iowa Falls Plant

Our Iowa Falls production plant began operations in November 2004 with an initial production capacity of 50 MMGPY. The plant is located on a 100-acre site southwest of Iowa Falls, Iowa. We completed an expansion of this facility to increase the productions capacity to 100 MMGPY in March 2006.

Our Iowa Falls plant transports ethanol by rail and truck, as needed, and has significant capacity for each form of transportation. The site is readily accessible by a road and rail for transport of large equipment, supplies and products. The Northern Natural Gas pipeline, which runs east of the Iowa Falls plant site, delivers natural gas to the plant.

Fairbank Plant

Our Fairbank production plant began operations in May 2006 with a production capacity of 105 MMGPY. The plant is located on a 100-acre site east of Fairbank, Iowa.

Our Fairbank plant transports ethanol by rail and truck, as needed, and has significant capacity for each form of transportation. The site is readily accessible by road and rail for transport of large equipment, supplies, and products. The main gas line is located approximately 7.5 miles east of the Fairbank plant and Northern Natural Gas has constructed a lateral gas line to reach the plant.

Potential future facility sites, acquisitions and facility expansions

We continue to monitor our options for expansion of our business as ethanol market demand grows and plan to add further ethanol capacity. We have identified and have options to purchase four additional sites that we believe are suitable for construction of ethanol production facilities. Because the ethanol industry is highly fragmented, we also may consider purchasing ethanol facilities if we believe such acquisitions would enhance our business or our strategic position in the industry. We also intend to evaluate opportunities to acquire additional ethanol storage or distribution facilities and related infrastructure.

Competition

The market in which we sell our ethanol is highly competitive. According to the RFA, world ethanol production rose to 12 billion gallons in 2005. Fuel-grade ethanol accounted for 73% of world production. The United States and Brazil are the world's largest producers of ethanol. According to RFA, as of May 2006, industry capacity in the United States was approximately 4.5 billion gallons per year, with an additional 2.0 billion gallons per year of capacity under construction. The ethanol industry in the United States consists of more than 90 production facilities and is primarily corn-based, while ethanol production in Brazil is primarily sugar cane-based.

We compete with Archer Daniels Midland—ADM, the largest ethanol producer in the United States with 1,070 million gallons of current annual capacity, representing approximately 25% of total production capacity in the United States. We also compete with other large ethanol producers such as VeraSun (230 MMGPY), Aventine (150 MMGPY), Cargill (120 MMGPY) and Abengoa (115 MMGPY). The industry is otherwise highly fragmented, with many small, independent firms and

farmer-owned cooperatives constituting the rest of the market. We compete with our competitors primarily on a national basis.

Ethanol is a commodity and as such is priced on a very competitive basis. We believe that our ability to compete successfully in the ethanol production industry depends on our ability to price our product competitively, which in turn depends on many factors, including our optimal locations, use of latest production technologies, economies of scale and ready access to efficient transportation infrastructure.

With respect to distillers grains, we compete with other suppliers (i.e., other ethanol producers) as well as a number of large and smaller suppliers of competing animal feed. We believe the principal competitive factors are price, proximity to purchasers and product quality.

Legislation

There have been various legislative incentives that have spurred growth in the ethanol industry. These incentives include:

Energy Policy Act

The Energy Policy Act of 2005 established the Renewable Fuels Standard that mandates minimum annual volumes of renewable fuel to be used by petroleum refiners in the fuel supply. The annual requirement grows to 7.5 billion gallons per year by 2012. The Energy Policy Act did not provide liability protection to refiners who use MTBE as a fuel additive after May 2006. Given the extent of the environmental concerns associated with MTBE, we believe that this has served as a catalyst to hasten the replacement of a major portion of the remaining MTBE volumes with ethanol. The Energy Policy Act also removed the oxygenate requirements that were put in place by the Clean Air Act. The Energy Policy Act included anti-backsliding provisions, however, that require refiners to maintain emissions quality standards in the fuels that they produce, thus providing continued opportunities for ethanol.

Federal blenders' credit

The federal government also supports ethanol by offering refiners and blenders volumetric ethanol excise tax credits, or VEETCs, that entitle them to $0.51 per gallon—$0.051 per gallon of gasoline for a 10% ethanol blend—tax credit against the excise tax they pay on gasoline. This tax credit was first implemented in 1979 and is scheduled to expire in 2010. The federal VEETC incentives, which are intended to make refiners indifferent to the transportation and other costs of blending ethanol as opposed to other additives, support the refiners' practice of substituting ethanol for gasoline to stretch gasoline supplies.

State and local incentives

Various state and local authorities, in support of their farm communities and promotion of fuels with environmental benefits like ethanol, also extend different forms of tax incentives. In 2001, the Iowa legislature enacted an ethanol tax incentive to encourage gas retailers to increase ethanol sales. Under the legislation, once ethanol reaches 60% of a retailer's total fuel sales, the retailer can qualify for a $0.025 income tax credit for each additional gallon of ethanol blend sold. This program gives retailers incentive to price ethanol at levels that increase ethanol use and to offer ethanol in more than one pump. In 2002, the legislature modified the tax incentive to allow ethanol used for E85 blending to be calculated in a retailer's total fuel sales.

In addition, 23 states have implemented incentives to encourage ethanol production that are most typically categorized as tax credits, producer payments, loans, grants or some other type of program. Midwestern states, the agricultural center of the United States, have initiated most of the programs and policies to foster ethanol production and development. States on the East and West Coasts also are

beginning to initiate ethanol production programs in connection with drives to construct ethanol plants in these states.

State legislation banning or significantly limiting the use of MTBE

In recent years, due to environmental concerns, 25 states, including California, Connecticut and New York, have banned, or significantly limited, the use of MTBE. Ethanol has served as a replacement for much of the discontinued MTBE volumes and is expected to continue to replace future MTBE volumes that are removed from the fuel supply.

Federal tariff on imported ethanol

In 1980, Congress imposed a tariff on foreign produced ethanol, which typically is produced at significantly lower cost from sugar cane, to encourage the development of a domestic, corn-derived ethanol supply. This tariff was designed to prevent the federal tax incentive from benefiting non-U.S. producers of ethanol. The tariff is $0.54 per gallon and is scheduled to expire in 2007. In addition, there is a flat 2.5% ad valorem tariff on all imported ethanol.

Ethanol imports from 24 countries in Central America and the Caribbean Islands are exempt under the Caribbean Basin Initiative from the tariff. The Caribbean Basin Initiative provides that specified nations may export an aggregate of 7.0% of U.S. ethanol production per year into the U.S., with additional exemptions from ethanol produced from feedstock in the Caribbean region over the 7.0% limit. As a result of new plants under development, we believe imports from the Caribbean region will continue, subject to the limited nature of the exemption.

Environmental Matters

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 the health and safety of our employees. These laws and regulations can require expensive pollution control equipment or operational changes to limit actual or potential impacts to the environment. A violation of these laws and regulations or permit conditions can result in substantial fines, natural resource damage claims, criminal sanctions, permit revocations and facility shutdowns. We do not anticipate a material adverse effect on our business or financial condition as a result of our efforts to comply with these requirements. We also do not expect to incur material capital expenditures for environmental controls in this or the succeeding fiscal year.

There is a risk of liability for the investigation and cleanup of environmental contamination at each of the properties that we own or operate and at off-site locations where we arranged for the disposal of hazardous substances. If these substances have been or are disposed of or released at sites that undergo investigation or remediation by regulatory agencies, we may be responsible under CERCLA or other environmental laws for all or part of the costs of investigation or remediation and for damage to natural resources. We also may 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 these properties. Some of these matters may require us to expend significant amounts for investigation and/or cleanup or other costs. We do not have material environmental liabilities relating to contamination at or from our facilities or at off-site locations where we have transported or arranged for the disposal of hazardous substances.

In addition, new laws, new interpretations of existing laws, increased governmental enforcement of environmental laws or other developments could require us to make additional significant expenditures. Continued government and public emphasis on environmental issues can be expected to result in increased future investments for environmental controls at our ongoing operations. Present and future environmental laws and regulations and related interpretations applicable to our operations, more

vigorous enforcement policies and discovery of currently unknown conditions may require substantial capital and other expenditures. Our air emissions are subject to the federal Clean Air Act, the federal Clean Air Act Amendments of 1990 and similar state and local laws and associated regulations. The U.S. EPA has promulgated National Emissions Standards for Hazardous Air Pollutants, or NESHAP, under the federal Clean Air Act that could apply to facilities that we own or operate if the emissions of hazardous air pollutants exceed certain thresholds. If a facility we operate is authorized to emit hazardous air pollutants above the threshold level, then we would be required to comply with the NESHAP related to our manufacturing process and would be required to come into compliance with another NESHAP applicable to boilers and process heaters by September 13, 2007. New or expanded facilities would be required to comply with both standards upon startup if they exceed the hazardous air pollutant threshold. In addition to costs for achieving and maintaining compliance with these laws, more stringent standards also may limit our operating flexibility. Because other domestic ethanol manufacturers will have similar restrictions, however, we believe that compliance with more stringent air emission control or other environmental laws and regulations is not likely to materially affect our competitive position.

The hazards and risks associated with producing and transporting our products, such as fires, natural disasters, explosions, abnormal pressures, blowouts and pipeline ruptures also may 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. Our coverage includes physical damage to assets, employer's liability, comprehensive general liability, automobile liability and workers' compensation. We believe that our insurance is adequate and customary for our industry, but losses could occur for uninsurable or uninsured risks or in amounts in excess of existing insurance coverage. We do not currently have pending material claims for damages or liability to third parties relating to the hazards or risks of our business.

Employees

As of April 30, 2006, we had approximately 85 full-time employees, including approximately 67 involved in the operation and maintenance of our plants and 18 who are responsible for our management, marketing, project management, logistics and administration. There are no collective bargaining agreements covering any of our employees and our highly trained non-union labor force is a key advantage for our business. We have had no labor-related work stoppages and we believe our relations with our employees are satisfactory.

Board Structure

Our by-laws provide for a board of directors consisting of at least two and up to members. Our board of directors comprises members. Pursuant to the terms of our amended and restated security holders agreement, THL will have the right to nominate 4 directors, Hawkeye Holdings, L.L.C. (or its direct and indirect transferees) will have the right to nominate one director and our chief executive officer will be nominated as a director.

Committees of the Board

If the underwriters do not exercise their option to purchase additional shares or exercise such option for less than shares, we will continue to be a "controlled company" as set forth in Section 303A of the New York Stock Exchange Listed Company Manual because more than 50% of our voting power will be held by THL. Under the New York Stock Exchange rules, a "controlled company" may elect not to comply with certain New York Stock Exchange corporate governance requirements, including (1) the requirement that a majority of the board of directors consist of independent directors, (2) the requirement that the nominating and corporate governance committee be composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities, (3) the requirement that the compensation committee be composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities and (4) the requirement for an annual performance evaluation of the nominating and corporate governance and compensation committees. Following this offering, if we qualify, we intend to elect to be treated as a controlled company and thus utilize these exemptions. As a result, although we will have adopted charters for our audit, nominating and corporate governance and compensation committees and intend to conduct annual performance evaluations of these committees, our board may not consist of a majority of independent directors nor may our nominating and corporate governance and compensation committees consist of independent directors. Accordingly, so long as we are a "controlled company," you may not have the same protections afforded to stockholders of companies that are subject to all of the New York Stock Exchange corporate governance requirements.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

The THL Transactions

The Membership Interest Purchase Agreement

On May 11, 2006, a number of investment vehicles affiliated with Thomas H. Lee Partners, L.P., entered into a membership interest purchase agreement with Hawkeye Holdings, L.L.C., Hawkeye Renewables, LLC and THL–Hawkeye Acquisition LLC. The Purchase Agreement provides for a series of transactions that will result in THL purchasing from Hawkeye Holdings, L.L.C. an approximate 80% preferred and common equity interest in our business, with Hawkeye Holdings, L.L.C. retaining an approximate 20% preferred and common equity interest, in each case before dilution for restricted equity issued to our senior management.

Pursuant to the membership interest purchase agreement, THL agreed to acquire an approximate 80% interest in our business in a transaction that valued our business at approximately $1.0 billion. The membership interest purchase agreement contains customary representations and warranties including representations and warranties regarding organization, authorization, non-contravention, governmental consents, financial statements, absence of certain changes, no undisclosed material liabilities, material contracts, compliance with laws and court orders, litigation, title to real property, intellectual property rights, licenses and permits, tax matters, employee plans, environmental compliance and brokers. THL's right to obtain indemnification from Hawkeye Holdings, L.L.C. for any breach of these representations and warranties generally is limited to an aggregate amount of losses in excess of $12.5 million, subject to a cap of $60.0 million. The indemnity agreement expires, other than with respect to limited matters, one year after the closing date.

Immediately prior to closing the acquisition, Hawkeye Holdings, L.L.C. will form Hawkeye Intermediate LLC, which will become a new intermediate holding company of Hawkeye Renewables, LLC, our operating subsidiary. Hawkeye Holdings, L.L.C. will exchange 100% of its ownership interests in Hawkeye Renewables for common and preferred ownership interests in Hawkeye Intermediate LLC. THL will acquire approximately 80% of these interests at closing to effect the acquisition contemplated by the membership purchase agreement. Hawkeye Holdings L.L.C. will retain common and preferred interests in Hawkeye Intermediate LLC representing its approximate 20% ownership interest in our business.

THL–Hawkeye Acquisition LLC was formed by THL to finance in part the transactions contemplated by the membership interest purchase agreement. THL-Hawkeye Acquisition LLC will borrow $650 million of term debt and will obtain a $50 million revolving credit facility under our 2006 senior secured credit facilities described under "Description of Indebtedness". This term debt, together with $390 million of preferred and common equity from Hawkeye Intermediate LLC, will be used to pay the purchase price for the acquisition, refinance our existing debt and pay transaction expenses. Immediately following the closing of the THL Transactions, Hawkeye Acquisition LLC will merge into Hawkeye Renewables, which will assume the indebtedness described herein.

In connection with the THL Transactions, the parties will enter into the following agreements:

Limited Liability Company Agreement of Hawkeye Intermediate LLC

The amended and restated limited liability company agreement of Hawkeye Intermediate LLC to be entered into in connection with the THL Transactions will authorize Hawkeye Intermediate LLC to issue preferred units, Class A common units and Class B common units. The preferred units will be non-voting redeemable preferred interests entitled to an accruing yield of 8% per year, compounding annually, from the date of issuance. The Class A common units and Class B common units generally have rights and preferences that are similar to each other, except that the Class B common units, which will be issued to our management, are nonvoting and have different rights as to certain distributions. In the Conversion, Hawkeye Holdings Inc. will acquire all of the preferred units, Class A common units

and Class B common units in Intermediate LLC in exchange for mandatorily redeemable preferred stock and common stock of Hawkeye Holdings Inc. See "The Conversion."

Securityholders' Agreement

Pursuant to the securityholders' agreement to be entered into in connection with the THL Transactions, units of Hawkeye Intermediate LLC that are beneficially owned by THL, Hawkeye Holdings, L.L.C. and our management are subject to voting requirements with respect to the board of managers, restrictions on transfer and certain preemptive and registration rights.

The securityholders' agreement will be amended in connection with the Conversion to provide for, among other things:

•: the right of Hawkeye Holdings, L.L.C. (or its direct and indirect transferees) to nominate one member of our board of directors, the right of THL or its designees to nominate four members of our board of directors and the designation of our chief executive officer as a member of the board of directors;
•: the board to consist of six members and the board to have the right to appoint up to three additional independent directors;
•: in the event that THL transfers any of its common stock to a third party, THL, if it so elects, may permit the transferee to have the right to nominate a number of THL Directors in proportion to the number of shares so transferred, provided that the transferee executes and agrees to be bound by and subject to the securityholders' agreement;
•: in the event that we cease to be a "controlled company" within the meaning of the New York Stock Exchange corporate governance standards, the rights described in the preceding three bulleted paragraphs will cease to apply; and
•: registration rights, which will generally require us to register shares of our common stock held by the stockholders party to the securityholders agreement under the Securities Act.

THL Management Agreement

Upon the consummation of this offering, the management agreement described below will terminate pursuant to its terms and no termination payment will be required.

Pursuant to the management agreement to be entered into in connection with the THL Transactions, THL Managers VI, LLC will render to Hawkeye Renewables advisory and consulting services. In consideration of those services, Hawkeye Renewables will pay to THL Managers VI, LLC semi-annually, an aggregate annual management fee equal to the greater of:

•: $2.0 million; and
•: an amount equal to 1.0% of the adjusted earnings before interest, taxes, depreciation and amortization of Hawkeye Renewables for such fiscal year, but before deduction of any such fee.

Hawkeye Renewables also will pay THL Managers VI, LLC at the closing of the THL Transactions a transaction advisory fee of $20.0 million.

Hawkeye Renewables, LLC will also agree to indemnify THL Managers VI, LLC and its affiliates from and against all losses, claims, damages and liabilities arising out of or related to the performance by THL Managers VI, LLC of the services pursuant to the management agreement.

Management Investment

In connection with the THL Transactions, Bruce Rastetter and J.D. Schlieman, through their continuing ownership interest in Hawkeye Holdings, L.L.C., will continue to own an indirect equity investment in the preferred and common equity interests of Hawkeye Intermediate LLC valued at approximately $ million and $ , respectively, based on the price paid by THL in the THL

Transactions. Immediately prior to this offering, Hawkeye Holdings, L.L.C. is expected to distribute all of the shares of our preferred and common stock to its members who will make similar distributions. As a result of these distributions, Mr. Rastetter and Mr. Schlieman will directly own shares of our preferred and common stock. Mr. Rastetter will beneficially own approximately % of our common stock and Mr. Schlieman will beneficially own approximately % of our common stock.

Restricted Unit Agreements

In connection with the THL Transactions, members of senior management will be granted Class B common units of Hawkeye Intermediate LLC pursuant to restricted unit agreements entered into on the closing date of the THL Transactions.

The Class B common units to be granted to management and employees will be subject to vesting requirements under restricted unit agreements.

In connection with the Conversion, holders of Class B common units will contribute their Class B common units to Hawkeye Holdings Inc. in exchange for the number of shares of its common stock that our Board of Directors determines in good faith to have a fair value equal to the fair value of the Class B common units being exchanged. The vesting schedule applicable to the Class B common units will continue to apply to the shares of common stock received in the exchange.

The Conversion

Prior to this offering, we conducted our business through a number of limited liability companies. Hawkeye Holdings, L.L.C., formerly known as Iowa Falls Ethanol Plant, L.L.C., was organized in Iowa on October 22, 2003, and we commenced our business under Hawkeye Holdings, L.L.C. On February 22, 2005, Hawkeye Holdings, L.L.C., formed a wholly-owned subsidiary, Hawkeye Renewables, LLC, a Delaware limited liability company, and transferred substantially all of its assets and liabilities to the newly formed operating company. On June , 2006, in connection with THL's acquisition of approximately 80% of our business, Hawkeye Intermediate LLC will be formed and become the holding company of Hawkeye Renewables. Immediately prior to the effectiveness of the registration statement of which this prospectus is a part, Hawkeye Holdings Inc., a recently formed Delaware corporation, will become a holding company for our business, by entering into the following transactions:

•: The affiliates and co-investors of Thomas H. Lee Partners, L.P. holding preferred units and Class A common units in Hawkeye Intermediate LLC will either be merged with and into Hawkeye Holdings Inc. or will contribute all of their preferred units and Class A common units in Hawkeye Intermediate LLC to Hawkeye Holdings Inc. in exchange for an aggregate of shares of its common stock and an aggregate of shares of its mandatorily redeemable preferred stock;
•: Hawkeye Holdings, L.L.C. will contribute all of its preferred units and Class A common units in Hawkeye Intermediate LLC to Hawkeye Holdings Inc. in exchange for shares of its common stock and shares of its mandatorily redeemable preferred stock, which shares will be distributed by Hawkeye Holdings, L.L.C. to its members, who will make similar distributions; and
•: Our senior managers who will hold Class B common units in Hawkeye Intermediate LLC will contribute all of their Class B common units in Intermediate LLC to Hawkeye Holdings Inc. in exchange for an aggregate of shares of its common stock, which shares are subject to vesting.

As a result of the Transactions, Hawkeye Holdings Inc. will own all of the outstanding member interests of Hawkeye Intermediate LLC. Hawkeye Holdings Inc. is a Delaware corporation, and as such is subject to federal and state income taxes. Hawkeye Renewables, our operating company, and Hawkeye Intermediate LLC, our previous holding company, are limited liability companies not subject

to federal or state income taxes, and as such, the historical financial data included in this prospectus do not reflect what our financial position and results of operations would have been had we been taxable as a corporation. See "Risk Factors—Risks Relating to Our Business and Industry—We are currently unable to accurately predict what our short-term and long-term effective tax rates will be in the future."

Tax Receivables Agreement

We anticipate that the consummation of the Transactions will result in an increase in the tax basis of our tangible and intangible assets. Consequently, we expect that this increase in tax basis will reduce the amount of tax that we would have paid in the future without regard to the Transactions. We will enter into a tax receivables agreement with THL and Hawkeye Holdings, L.L.C. that will provide for the payment by us to these persons of the amount of cash savings, if any for any taxable year, in U.S. Federal income and Iowa franchise taxes that we actually realize as a result of this increase in tax basis and of certain other tax benefits relating to payments made under the tax receivables agreement. We will have the right to terminate the tax receivables agreement at any time for an amount based on an assumed value of certain payments remaining to be made under the tax receivables agreement at such time. While the actual amount and timing of any payments under this agreement will vary depending upon a number of factors, we expect that, as a result of the size of the increase in the tax basis of our tangible and intangible assets, during the amortization period for such assets, the payments that may be made to these persons may be substantial.

DESCRIPTION OF INDEBTEDNESS

2006 Senior Secured Credit Facilities

As part of the THL Transactions, Hawkeye Renewables will enter into new $700.0 million senior secured credit facilities, including a $50.0 million revolving credit facility.

The 2006 senior secured credit facilities will be used to finance, in part, the THL Transactions and to pay related fees, expenses and premiums. The revolving credit facility also will be available, subject to certain conditions, for our working capital and general corporate purposes. Amounts borrowed under our 2006 senior secured term facilities that are repaid or prepaid may not be reborrowed. Amounts repaid under our revolving credit facility may be reborrowed. A portion of the revolving credit facility will be available for letters of credit. The obligations under our 2006 senior secured credit facilities will be guaranteed by, and secured by a lien on, substantially all of the assets of Hawkeye Intermediate, Hawkeye Renewables and each of existing and subsequently acquired or organized domestic subsidiaries of Hawkeye Renewables other than D&W Railroad LLC. The priorities and relative rights of the lenders under the first lien credit facilities and the second lien term facility will be governed by a customary intercreditor agreement.

Interest Rates

Borrowings under our 2006 senior secured credit facilities bear interest, at our option, at the following rates per year:

The definitive documentation governing first lien credit facilities will contain provisions under which, from and after the date of delivery of our financial statements for the first fiscal quarter after the closing date of the THL Transactions, and, so long as no default shall have occurred and be continuing, interest rates under the revolving credit facility will be subject to change in increments to be agreed upon. We may elect interest periods of one, two, three or six months (or, if agreed to by all relevant lenders, nine or 12 months) for Adjusted LIBOR borrowings. Calculation of interest will be on the basis of the actual days elapsed in a year of 360 days (or 365 or 366 days, as the case may be, in the case of ABR loans based on the Prime Rate) and interest shall be payable at the end of each interest period and, in any event, at least every three months.

ABR is the Alternate Base Rate, which is the higher of Credit Suisse's Prime Rate and the Federal Funds Effective Rate plus ¹/2 of 1% per year. Adjusted LIBOR will at all times include statutory reserves.

Mandatory and Voluntary Prepayments

We will be required to make mandatory prepayments with respect to certain proceeds of asset sales and the incurrence of additional debt, as well as with a certain percentage of "excess cash flow" from the previous fiscal year. The foregoing mandatory prepayments shall be applied:

Covenants

The definitive documentation with respect to our 2006 senior secured credit facilities will contain affirmative and negative covenants and requirements affecting us and our subsidiaries. In general, the affirmative covenants provide for, among other requirements, delivery of financial statements and other financial information to the lenders and notice to the lenders upon the occurrence of certain events. The affirmative covenants also include standard covenants relating to the operation of our and our subsidiaries' business.

The definitive documentation with respect to our 2006 senior secured credit facilities also will contain negative covenants and restrictions on our and our subsidiaries actions, including incurrence of additional indebtedness, restrictions on dividends and other restricted payments, prepayments of debt, liens, sale-leaseback transactions, loans and investments, hedging arrangements, mergers, transactions with affiliates, changes in business, asset sales, amendments of material debt and other agreements and capital expenditures. The definitive documentation with respect to our 2006 senior secured credit facilities also will require that we meet certain financial covenants, ratios and tests, including maximum leverage ratios and a minimum interest coverage ratio.

Change of Control

In the event of a change of control, we will be required to:

Events of Default

The definitive documentation governing our 2006 senior secured credit facilities specifies certain customary events of default including non-payment of principal or interest, violation of covenants, inaccuracy of representations and warranties in any material respect, cross default or cross acceleration of certain other indebtedness and agreements, bankruptcy and insolvency events, material judgments and liabilities, certain ERISA events, invalidity of guarantees and certain other documents under the 2006 senior secured credit facilities and change of control.

Fees and Expenses

We are required to pay certain on-going fees in connection with our 2006 senior secured credit facilities, including letter of credit fees, agency fees, and commitment fees. Commitment fees are payable quarterly in arrears, initially at a rate per year of 0.50% on the average daily unused portion of the revolving credit facility. After the date of delivery of our financial statements for the first fiscal quarter after the closing date of the THL Transactions, and, so long as no default shall have occurred and be continuing, commitment fees under the revolving credit facility will be subject to change in increments to be agreed upon.

2005 Senior Secured Term Loan Facility

On February 24, 2005, we entered into a credit agreement establishing a $185.0 million senior secured term loan facility, the proceeds of which were used to finance the expansion of the Iowa Falls plant and construction of the Fairbank plant, to pay down an existing bank loan of $24.0 million associated with the Iowa Falls plant, to fund a 12-month debt service reserve, to pay fees and expenses related to the senior secured term loan facility and the credit agreement and to fund other transaction expenses. The term loan matures on January 31, 2012 and requires quarterly principal payments starting July 31, 2006.

In connection with the senior secured term loan facility, we entered into the credit agreement. Our obligations under the credit agreement are secured by substantially all of our assets and contains prepayment penalties. We are obligated to apply a portion of our excess cash flow to principal payments in order to meet the schedule of maximum outstanding debt levels. The term loan facility bears interest at a six-month LIBOR rate plus 2.875%. As of December 31, 2005, there was an outstanding balance of $185.0 million under the credit agreement.

In connection with the THL Transactions, we will repay and retire the existing credit facility and our $55.6 million subordinated notes.

DESCRIPTION OF CAPITAL STOCK

The following describes our common stock, preferred stock, certificate of incorporation and bylaws that will be in effect following the Conversion and which will take place immediately prior to this offering. We encourage you to read the complete text of our certificate of incorporation and bylaws, which we have filed as exhibits to the registration statement of which this prospectus is a part. These documents will become effective at the time of the Conversion without substantive change.

Authorized Capital

Our authorized capital stock consists of 205 million shares of common stock, par value $0.001 per share of which shares will be issued and outstanding prior to this offering, and shares of preferred stock. Immediately following the completion of this offering there are expected to be shares of common stock outstanding and no shares of preferred stock outstanding.

Common Stock

Voting

Except as otherwise required by Delaware law, at every annual or special meeting of stockholders, every holder of common stock is entitled to one vote per share. There is no cumulative voting in the election of directors. In addition, holders of our common stock are entitled to elect up to eight members of the board of directors.

Dividend Rights

Subject to dividend preferences that may be applicable to any outstanding preferred stock, holders of our common stock are entitled to receive ratably such dividends as may be declared from time to time by our board of directors out of funds legally available for that purpose. However, other than the special cash dividends to be paid in connection with this offering, we do not intend to pay cash dividends on our common stock for the foreseeable future. See "Dividend Policy."

Liquidation and Preemptive Rights

In the event of our liquidation, dissolution or winding up, the holders of our common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The holders of our common stock have no preemptive or other subscription rights. There are no redemption or sinking fund provisions applicable to our common stock. The outstanding shares of our common stock are, and the shares offered in this offering, when issued and paid for, will be, fully paid and non-assessable.

Preferred Stock

Our board of directors will have the authority, subject to any limitations imposed by law or New York Stock Exchange rules, without further action by the stockholders, to issue up to 5,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions of each series of such preferred stock. These rights, preferences and privileges include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of that series, any or all of which may be greater than the rights of common stock. The issuance of preferred stock could adversely affect the voting power of holders of common stock and the likelihood that those holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change in control of our company without further action by the stockholders.

Redeemable Preferred Stock

In connection with the Conversion, we will issue 1,000,000 shares of the 8% mandatorily redeemable preferred stock to THL and Hawkeye Holdings, L.L.C. in exchange for their preferred membership interests in Hawkeye Intermediate, LLC. We intend to use $ of the proceeds of this offering to redeem our redeemable preferred stock. Any redeemable preferred stock redeemed will be restored to the status of authorized-but-unissued shares of preferred stock described above.

Voting

Except as otherwise required by Delaware law, the redeemable preferred stock will not have voting rights, except that without the vote of holders of a majority of all shares of redeemable preferred stock outstanding, we may not:

•: amend or change the rights, preferences or privileges of the redeemable preferred stock;
•: increase the total number of authorized shares of redeemable preferred stock;
•: amend our Certificate of Incorporation, including the Certificate of Designation, Preferences and Rights, or by-laws in any manner that adversely affects the rights, preferences or privileges of the redeemable preferred stock;
•: redeem, purchase or otherwise acquire for value, or pay into or set aside for a sinking fund for such purposes, any share or shares of redeemable preferred stock otherwise than by redemption or conversion in accordance with the Certificate of Designation, Preferences and Rights; or
•: authorize or issue, or obligate itself to issue, any other equity security, including any security convertible into or exercisable for any equity security, senior to or on a parity with the redeemable preferred stock.

Dividend Rights

The redeemable preferred stock will accrue dividends at the rate of 8% on the $351.00 face amount per share of the redeemable preferred stock, calculated from the date of the THL Transactions through the date of redemption.

Liquidation and Preemptive Rights

If we liquidate, dissolve, or wind up, engage in a transaction that changes our control, or sell all or substantially all of our assets, the redeemable preferred stock will be redeemed for a liquidation amount equal to $351.00 per share plus accrued and unpaid dividends, prior to any payments or distributions made on our common stock. The redeemable preferred stock does not entitle its holders to preemptive or other subscription rights.

Redemption Rights

The redeemable preferred stock will be subject to automatic redemption to the extent of funds available therefor in this offering at a price per share equal to the liquidation amount. Any shares of redeemable preferred stock redeemed or that we otherwise acquire will be restored to the status of authorized-but-unissued shares of our preferred stock described above.

Right to Convert

Following the offering, if any shares of redeemable preferred stock remain outstanding, upon the election of either THL or Hawkeye Holdings, L.L.C., all then-outstanding shares of redeemable

preferred stock shall be redeemed for a number of shares of our common stock equal to the liquidation preference divided by the price paid for the shares of common stock in this offering.

Anti-Takeover Effects of our Certificate of Incorporation and By-laws

Our certificate of incorporation and by-laws will contain certain provisions that are intended to enhance the likelihood of continuity and stability in the composition of the board of directors and that may have the effect of delaying, deferring or preventing a future takeover or change in control of our company, even in those cases where such a transaction may be at a premium to the current market price of our common stock.

These provisions include:

Action by Written Consent; Special Meetings of Stockholders

Our certificate of incorporation will provide that stockholder action can be taken only at an annual or special meeting of stockholders and cannot be taken by written consent in lieu of a meeting. Our certificate of incorporation and the by-laws will provide that, except as otherwise required by law, special meetings of the stockholders can only be called by the chairman of the board, or pursuant to a resolution adopted by a majority of the board of directors. Stockholders will not be permitted to call a special meeting or to require the board of directors to call a special meeting.

Advance Notice Procedures

Our by-laws will establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed nominations of candidates for election to the board of directors. Stockholders at an annual meeting will be able to consider only proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the board of directors or by a stockholder who was a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has given our Secretary timely written notice, in proper form, of the stockholder's intention to bring that business before the meeting. Although the by-laws will not give the board of directors the power to approve or disapprove stockholder nominations of candidates or proposals regarding other business to be conducted at a special or annual meeting, the by-laws may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of Hawkeye Holdings Inc.

Authorized but Unissued Shares

Our authorized but unissued shares of common stock and preferred stock will be available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock and preferred stock could render more difficult or discourage an attempt to obtain control of a majority of our common stock by means of a proxy contest, tender offer, merger or otherwise.

Section 203 of Delaware Law

Upon consummation of the Conversion and this offering, we will elect not to be subject to the provisions of Section 203 of the Delaware General Corporation Law. Subject to exceptions specified therein, Section 203 of the Delaware General Corporation Law prohibits a publicly-held Delaware corporation from engaging in a "business combination" with an "interested stockholder," including

general mergers or consolidations or acquisitions of additional shares of the corporation, for a three-year period following the time that such stockholder became an interested stockholder.

Except as otherwise specified in Section 203, an "interested stockholder" is defined to include:

•: any person that is the owner of 15% or more of the outstanding voting stock of the corporation, or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately prior to the date of determination; and
•: the affiliates and associates of any such person.

The statute is intended to prohibit or delay mergers or other takeover or change in control attempts. Although we have elected to opt out of the statute's provisions, we could elect to be subject to Section 203 in the future.

Limitations on Liability and Indemnification of Officers and Directors

Our certificate of incorporation limits the liability of directors to the fullest extent permitted by the Delaware General Corporation Law. In addition, our certificate of incorporation provides that we shall indemnify our directors and officers to the fullest extent permitted by such law.

Registration Rights

NYSE Listing

We intend to apply to have our common stock listed on the New York Stock Exchange under the symbol " ."

SHARES ELIGIBLE FOR FUTURE SALE

Prior to this offering, there has been no public market for our common stock. Although we intend to apply for listing of the shares of our common stock on the New York Stock Exchange, we cannot assure you that a significant public market for our common stock will develop or be sustained. We cannot predict the effect, if any, that market sales of shares or the availability of shares for sale will have on the market price prevailing from time to time. As described below, only a limited number of shares, other than the shares sold in this offering, will be available for sale shortly after this offering due to contractual and legal restrictions on resale. Sales of our common stock in the public market after the restrictions lapse, or the perception that these sales may occur, could cause the market price of our common stock to decline.

Upon completion of this offering, we expect to have outstanding shares of common stock, or shares if the underwriters exercise their over-allotment option in full. Of these shares, the shares sold in this offering, or shares if the underwriters exercise their over-allotment option in full, will be freely tradable without restriction under the Securities Act except for any shares purchased by one of our "affiliates" as defined in Rule 144 under the Securities Act. All of the shares outstanding other than the shares sold in this offering (a total of shares, or shares if the underwriters exercise their over-allotment option in full) will be "restricted securities" within the meaning of Rule 144 under the Securities Act and subject to lock-up arrangements.

Lock-Up Agreements

We, our directors and executive officers and substantially all of our existing stockholders have entered into lock-up agreements with the underwriters. Under these agreements, subject to exceptions, we may not issue any new shares of common stock, and those holders of stock may not, directly or indirectly, offer, sell, contract to sell, pledge or otherwise dispose of or hedge any common securities convertible into or exchangeable for shares of common stock, or publicly announce the intention to do any of the foregoing, without the prior written consent of the underwriters for a period of 180 days from the date of this prospectus. This consent may be given at any time without public notice. In addition, during this 180-day period, we have also agreed not to file any registration statement for, and each of our officers and stockholders has agreed not to make any demand for, or exercise any right of, the registration of, any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock without the prior written consent of the underwriters. Transfers or dispositions can be made sooner only with the prior written consent of the underwriters. The underwriters have no present intent to release us or any of our directors, executive officers from the lock-up agreements.

Upon the expiration of these lock-up agreements, shares will be eligible for sale in the public market under Rule 144 of the Securities Act, subject to the restrictions contained therein.

Eligibility of Restricted Shares for Sale in the Public Market

Rule 144

In general, under Rule 144 as currently in effect, a person, or persons whose shares are aggregated, who has beneficially owned restricted securities for at least one year, including the holding period of any prior owner other than an affiliate, and who files a Form 144 with respect to this sale, will be entitled to sell within any three month period commencing 90 days after the date of the resale registration statement referred to above a number of shares of common stock that does not exceed the greater of:

•: 1.0% of the then outstanding shares of our common stock, or approximately shares immediately after this offering; or

•: the average weekly trading volume during the four calendar weeks preceding the date of which notice of the sale is filed on Form 144.

Sales under Rule 144 are also subject to restrictions relating to manner of sale and the availability of current public information about us.

Rule 144(k)

A person who is not deemed to have been our affiliate at any time during the 90 days immediately preceding a sale and who has beneficially owned his or her shares for at least two years, including the holding period of any prior owner other than an affiliate, is entitled to sell these shares of common stock pursuant to Rule 144(k) without regard to the volume limitations, manner of sale provisions, public information or notice requirements of Rule 144. Affiliates must always sell pursuant to Rule 144, even after the applicable holding periods have been satisfied.

Registration Rights

Pursuant to the securityholders' agreement to be entered into in connection with the THL Transactions, as amended in connection with the Conversion, holders of a majority of common stock held by THL and its affiliates are entitled to request up to two registrations of our common stock under the Securities Act. In addition, THL and its affiliates, on one hand, and Hawkeye Holdings, L.L.C. and its direct and indirect distributees, by action of the holders of at least 35% of the shares held thereby, on the other hand, are each entitled to request up to two registrations of our common stock on Form S-3 under the Securities Act in any twelve month period. All holders have the right to have their shares of common stock registered in connection with any registration statement (other than on Form S-8) that we propose to file. Any requested registration is subject to customary cut-backs and blackout periods. Each signatory of the securityholders' agreement agreed that in connection with any such registration, it will vote, or cause to be voted, all common stock over which that holder has power to vote to effect any stock split deemed necessary to facilitate the effectiveness of a requested registration. Following the offering stockholders that collectively own shares of our common stock will have registration rights with respect to their shares.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the material United States federal income tax considerations relating to the purchase, ownership and disposition of shares of our common stock, as of the date hereof. This summary deals only with shares of our common stock held as capital assets and does not deal with special situations. For example, this summary does not discuss:

•: tax consequences to holders who may be subject to special tax treatment, such as dealers in securities or currencies, financial institutions, regulated investment companies, real estate investment trusts, tax-exempt entities, traders in securities that elect to use a mark-to-market method of accounting for their securities or insurance companies, U.S. expatriates or former long-term residents of the United States;
•: tax consequences to persons holding shares of our common stock as part of a hedging, integrated, constructive sale, conversion transaction or straddle;
•: tax consequences to U.S. holders of shares of our common stock whose "functional currency" is not the U.S. dollar;
•: tax consequences to pass-through entities or investors in pass-through entities;
•: alternative minimum tax consequences, if any; or
•: any state, local or foreign tax consequences.

The discussion below is based upon the provisions of the Internal Revenue Code of 1986 and regulations, rulings and judicial decisions as of the date of this prospectus. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those discussed below. This summary does not discuss all aspects of U.S. federal income taxes and does not deal with all tax consequences that may be relevant to holders in light of their personal circumstances.

If a partnership holds shares of common stock, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding shares of our common stock, you should consult your tax advisor.

This discussion is for general information only and is not tax advice. If you are considering the purchase of shares of our common stock, you should consult your own tax advisors concerning the U.S. federal income tax consequences to you and any consequences arising under the laws of any state, local, foreign or other taxing jurisdiction. Each prospective investor should seek advice based on its particular circumstances from an independent tax advisor.

Consequences to U.S. Holders

The following is a summary of the U.S. federal income tax consequences that will apply to a U.S. holder of shares of our common stock. "U.S. holder" means a beneficial owner of a share of common stock that is:

•: an individual citizen or resident of the United States;
•: a corporation, or any other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the U.S., any state thereof or the District of Columbia;
•: an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

•: a trust if it is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust, or it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a United States person.

Dividend Distributions

If we make a distribution in respect of our stock, the distribution will be treated as a dividend to the extent it is paid from our current or accumulated earnings and profits. If the distribution exceeds current and accumulated earnings and profits, the excess will be treated as a nontaxable return of capital reducing the U.S. holder's adjusted tax basis in the U.S. holder's common stock to the extent of the U.S. holder's adjusted tax basis in that stock. Any remaining excess will be treated as capital gain. The Code provides for special treatment of dividends paid to individual taxpayers prior to 2011. If a U.S. holder is an individual, dividends received by such holder generally will be subject to a reduced maximum tax rate of 15% through December 31, 2010, after which the rate applicable to dividends is scheduled to return to the tax rate generally applicable to ordinary income. The rate reduction will not apply to dividends received to the extent that the U.S. holder elects to treat dividends as "investment income," which may be offset by investment expense. The rate reduction also will not apply to dividends that are paid to a U.S. holder with respect to shares of our common stock that are held by such holder for less than 61 days during the 121-day period beginning on the date that is 60 days before the date on which the shares of the stock became ex-dividend with respect to such dividend. If a U.S. holder is a U.S. corporation, it will be able to claim the deduction allowed to U.S. corporations in respect of dividends received from other U.S. corporations equal to a portion of any dividends received, subject to generally applicable limitations on that deduction. In general, a corporate U.S. holder may deduct 70% of the dividend it receives if such holder owns less than 20% of the voting power and value of our stock.

U.S. holders should consult their tax advisors regarding the holding period requirements that must be satisfied in order to qualify the dividends-received deduction and the reduced maximum tax rate on dividends.

Sale, Exchange, Redemption or Other Disposition of Stock

A U.S. holder generally will recognize capital gain or loss on a sale or exchange of our common stock. The U.S. holder's gain or loss will equal the difference between the amount realized by the U.S. holder and the U.S. holder's adjusted tax basis in the stock. The amount realized by the U.S. holder will include the amount of any cash and the fair market value of any other property received in exchange for the stock. Gain or loss recognized by a U.S. holder on a sale or exchange of stock will be long-term capital gain or loss if the holder held the stock for more than one year. Long-term capital gains of non-corporate taxpayers are taxed at lower rates than those applicable to ordinary income. The deductibility of capital losses is subject to certain limitations.

Information Reporting and Backup Withholding

When required, we or our paying agent will report to the holders of shares of our common stock and the Internal Revenue Service amounts paid on or with respect to the common stock during each calendar year and the amount of tax, if any, withheld from such payments. A U.S. holder will be subject to backup withholding on dividends paid on the common stock and proceeds from the sale of the common stock at the applicable rate, which currently is 28%, if the U.S. holder:

•: fails to provide us or our paying agent with a correct taxpayer identification number or certification of exempt status, such as certification of corporate status,

•: has been notified by the IRS that it is subject to backup withholdings as a result of the failure to properly report payments of interest or dividends, which notification has not been withdrawn, or
•: in certain circumstances, has failed to certify under penalty of perjury that it is not subject to backup withholding.

A U.S. holder may be eligible for an exemption from backup withholding by providing a properly completed IRS Form W-9 to us or our paying agent. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a U.S. holder's U.S. federal income tax liability provided the required information is properly furnished to the IRS on a timely basis.

Consequences to Non-U.S. Holders

The following is a summary of the U.S. federal income tax consequences that will apply to a non-U.S. holder of shares of our common stock. The term "non-U.S. holder" means a beneficial owner of shares of common stock, other than a partnership, that is not a U.S. holder. Special rules may apply to certain non-U.S. holders such as "controlled foreign corporations" or "passive foreign investment companies." Such entities should consult their own tax advisors to determine the U.S. federal, state, local and other tax consequences that may be relevant to them.

Dividend Distributions

Any dividends paid with respect to the shares of common stock will be subject to withholding tax at a 30% rate or such lower rate as specified by an applicable income tax treaty. Dividends that are effectively connected with the conduct of a trade or business within the United States and, where an applicable tax treaty so provides, are attributable to a U.S. permanent establishment, however, are not subject to the withholding tax, but instead are subject to U.S. federal income tax on a net income basis at applicable graduated individual or corporate rates. Certain certification and disclosure requirements must be complied with in order for effectively connected income to be exempt from withholding. Any such effectively connected dividends received by a foreign corporation may, under certain circumstances, be subject to an additional branch profits tax at a 30% rate or such lower rate as specified by an applicable income tax treaty.

A non-U.S. holder of shares of common stock who wishes to claim the benefit of an applicable treaty rate is required to satisfy applicable certification and other requirements. If a non-U.S. holder is eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty, the holder may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS.

Sale, Exchange, Redemption or Other Disposition of Stock

Any gain realized by a non-U.S. holder upon the sale, exchange, redemption or other taxable disposition of shares of common stock will not be subject to U.S. federal income tax unless:

•: that gain is effectively connected with the conduct of a trade or business in the United States and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment;
•: the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met; or
•: we are or have been a "United States real property holding corporation" for U.S. federal income tax purposes and, in the case where our common stock is "regularly traded on an established securities market," the non-U.S. holder holds or has held, directly or indirectly, at any time within the shorter of the five-year period preceding disposition or the non-U.S. holder's

holding period for the shares of common stock, more than 5% of our common stock. In the case where our common stock is not "regularly traded on an established securities market," the 5% threshold does not apply. We are not, and do not anticipate that we will become, a "United States real property holding corporation" for U.S. federal income tax purposes.

An individual non-U.S. holder having gain described in the first bullet point above will be subject to U.S. federal income tax on the net gain derived from the sale in the same manner as a U.S. holder. An individual non-U.S. holder described in the second bullet point above will be subject to a flat 30% U.S. federal income tax on the gain derived from the sale, which may be offset by U.S. source capital losses, even though the holder is not considered a resident of the U.S. If a non-U.S. holder is eligible for the benefits of a tax treaty between the United States and its country of residence, any such gain will be subject to United States federal income tax in the manner specified by the treaty and generally only will be subject to such tax if such gain is attributable to a permanent establishment maintained by the non-U.S. Holder in the United States and the non-U.S. holder claims the benefit of the treaty by properly submitting an IRS Form W-8BEN or suitable successor or substitute form. A non-U.S. holder that is a foreign corporation and has gain described in the first bullet point above will be subject to tax on gain under regular graduated U.S. federal income tax rates and, in addition, may be subject to a branch profits tax at a 30% rate or a lower rate if so specified by an applicable income tax treaty.

Federal Estate Tax

If a non-U.S. holder is an individual, common stock held at the time of the holder's death will be included in the holder's gross estate for U.S. federal estate tax purposes, and may be subject to U.S. federal estate tax, unless an applicable estate tax treaty provides otherwise.

Information Reporting and Backup Withholding

We must report annually to the IRS the amount of dividends or other distributions we pay to you on shares of our common stock and the amount of tax, if any, we withhold on these distributions. Copies of the information returns reporting such distributions and any withholding also may be made available to the tax authorities in the country in which the holder resides under the provisions of an applicable income tax treaty.

The United States imposes a backup withholding tax on dividends and certain other types of payments to U.S. persons. A non-U.S. holder will not be subject to backup withholding tax on dividends the holder receives on shares of our common stock if the holder provides proper certification, usually on an IRS Form W-8BEN, of the holder's status as a non-U.S. person or other exempt status.

Information reporting and backup withholding generally are not required with respect to the amount of any proceeds from the sale of shares of our common stock outside the United States through a foreign office of a foreign broker that does not have certain specified connections to the United States. However, if a non-U.S. holder sells shares of our common stock through a United States broker or the U.S. office of a foreign broker, the broker will be required to report the amount of proceeds paid to the non-U.S. holder to the IRS and also withhold on that amount unless the non-U.S. holder provides appropriate certification (usually on an IRS Form W-8BEN) to the broker of the holder's status as a non-U.S. person or other exempt status.

Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a non-U.S. holder's U.S. federal income tax liability provided the required information properly is furnished to the IRS on a timely basis.

UNDERWRITING

Under the terms and subject to the conditions contained in an underwriting agreement dated , 2006, we have agreed to sell to the underwriters named below, for whom Credit Suisse Securities (USA) LLC, Morgan Stanley & Co. Incorporated and Banc of America Securities LLC are acting as representatives, and each underwriter has severally agreed to purchase, the following respective numbers of shares of common stock:

Underwriter			Number of Shares
Credit Suisse Securities (USA) LLC
Morgan Stanley & Co. Incorporated
Banc of America Securities LLC

	Total

The underwriting agreement provides that the underwriters are obligated to purchase all the shares of common stock in the offering if any are purchased, other than those shares covered by the over-allotment option described below. The underwriting agreement also provides that if an underwriter defaults the purchase commitments of non-defaulting underwriters may be increased or the offering may be terminated.

We have granted to the underwriters a 30-day option to purchase on a pro rata basis up to additional shares at the initial public offering price less the underwriting discounts and commissions. The option may be exercised only to cover any over-allotments of common stock.

The underwriters propose to offer the shares of common stock initially at the public offering price on the cover page of this prospectus and to selling group members at that price less a selling concession of $ per share. The underwriters and selling group members may allow a discount of $ per share on sales to other broker/dealers. After the initial public offering the representatives may change the public offering price and concession and discount to broker/dealers.

The following table summarizes the compensation and estimated expenses we will pay:

	Per Share		Total
	Without Over-allotment	With Over-allotment	Without Over-allotment	With Over-allotment
Underwriting discounts and commissions paid by us	$	$	$	$
Expenses paid by us	$	$	$	$

We estimate that our out of pocket expenses for this offering will be approximately $ .

The representatives have informed us that they do not expect sales to accounts over which the underwriters have discretionary authority to exceed 5% of the shares of common stock being offered.

We have agreed that we will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Securities and Exchange Commission a registration statement under the Securities Act relating to, any additional shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing, without the prior written consent of Credit Suisse Securities (USA) LLC and Morgan Stanley & Co. Incorporated for a period of 180 days after the date of this prospectus except that we may:

•: issue shares of our common stock in this offering;

•: issue shares of our common stock pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options, in each case outstanding on the date of this prospectus;
•: issue shares of our common stock pursuant to the exercise of such options or other equity awards; or
•: file with the SEC one or more registration statements on Form S-8 registering the shares of our common stock issuable under our equity compensation plans in effect on the date of this prospectus, in each case subject to no further transfer during the "lock-up" period.

However, in the event that either (1) during the last 17 days of the "lock-up" period, we release earnings results or material news or a material event relating to us occurs or (2) prior to the expiration of the "lock-up" period, we announce that we will release earnings results during the 16-day period beginning on the last day of the "lock-up" period, then in either case the expiration of the "lock-up" will be extended until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of the material news or event, as applicable, unless Credit Suisse Securities (USA) LLC and Morgan Stanley & Co. Incorporated waive, in writing, such an extension.

Our officers and directors have agreed that they will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, enter into a transaction that would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of our common stock, whether any of these transactions are to be settled by delivery of our common stock or other securities, in cash or otherwise, or publicly disclose the intention to make any offer, sale, pledge or disposition, or to enter into any transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of Credit Suisse Securities (USA) LLC and Morgan Stanley & Co. Incorporated for a period of 180 days after the date of this prospectus. However, in the event that either (1) during the last 17 days of the "lock-up" period, we release earnings results or material news or a material event relating to us occurs or (2) prior to the expiration of the "lock-up" period, we announce that we will release earnings results during the 16-day period beginning on the last day of the "lock-up" period, then in either case the expiration of the "lock-up" will be extended until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of the material news or event, as applicable, unless Credit Suisse Securities (USA) LLC and Morgan Stanley & Co. Incorporated waive, in writing, such an extension.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act and to contribute to payments that the underwriters may be required to make in that respect.

We intend to apply to list the shares of common stock on The New York Stock Exchange under the symbol " ."

Each of the underwriters has represented and agreed that:

(a): it has not made or will not make an offer of shares to the public in the United Kingdom within the meaning of section 102B of the Financial Services and Markets Act 2000 (as amended) ("FSMA") except to legal entities which are authorized or regulated to operate in the financial markets or, if not so authorized or regulated, whose corporate purpose is solely to invest in securities or otherwise in circumstances which do not require the publication by the company of a prospectus pursuant to the Prospectus Rules of the Financial Services Authority ("FSA");

(b): it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of section 21 of FSMA) to persons who have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 or in circumstances in which section 21 of FSMA does not apply to the company; and
(c): it has complied with, and will comply with all applicable provisions of FSMA with respect to anything done by it in relation to the shares in, from or otherwise involving the United Kingdom.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a "Relevant Member State"), each Underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the "Relevant Implementation Date") it has not made and will not make an offer of shares to the public in that Relevant Member State prior to the publication of a prospectus in relation to the shares which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the Relevant Implementation Date, make an offer of Shares to the public in that Relevant Member State at any time:

(a): to legal entities which are authorized or regulated to operate in the financial markets or, if not so authorized or regulated, whose corporate purpose is solely to invest in securities;
(b): to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000 and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts; or
(c): in any other circumstances which do not require the publication by the Issuer of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression an "offer of Shares to the public" in relation to any shares in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the shares to be offered so as to enable an investor to decide to purchase or subscribe the shares, as the same may be varied in that Relevant Member State by any measure implementing the Prospectus Directive in that Relevant Member State and the expression Prospectus Directive means Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

The shares may not be offered or sold by means of any document other than to persons whose ordinary business is to buy or sell shares or debentures, whether as principal or agent, or in circumstances which do not constitute an offer to the public within the meaning of the Companies Ordinance (Cap. 32) of Hong Kong, and no advertisement, invitation or document relating to the shares may be issued, whether in Hong Kong or elsewhere, which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to shares which are or are intended to be disposed of only to persons outside Hong Kong or only to "professional investors" within the meaning of the Securities and Futures Ordinance (Cap. 571) of Hong Kong and any rules made thereunder.

This prospectus has not been registered as a prospectus with the Monetary Authority of Singapore. Accordingly, this prospectus and any other document or material in connection with the offer or sale, or invitation or subscription or purchase, of the securities may not be circulated or distributed, nor may the securities be offered or sold, or be made the subject of an invitation for subscription or purchase,

whether directly or indirectly, to persons in Singapore other than under circumstances in which such offer, sale or invitation does not constitute an offer or sale, or invitation for subscription or purchase, of the securities to the public in Singapore.

The securities have not been and will not be registered under the Securities and Exchange Law of Japan (the Securities and Exchange Law) and each underwriter has agreed that it will not offer or sell any securities, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan (which term as used herein means any person resident in Japan, including any corporation or other entity organized under the laws of Japan), or to others for re-offering or resale, directly or indirectly, in Japan or to a resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the Securities and Exchange Law and any other applicable laws, regulations and ministerial guidelines of Japan.

Certain of the underwriters and their respective affiliates have performed and may in the future perform investment banking, financial advisory and lending services for us and our affiliates from time to time, for which they have received customary compensation, and may do so in the future.

An affiliate of Credit Suisse Securities (USA) LLC is a lender under our 2005 senior secured term loan facility and Credit Suisse Securities (USA) LLC was a sole bookrunner and sole lead arranger under our 2005 senior secured term loan facility.

Credit Suisse Securities (USA) LLC is also acting as advisor to certain of our existing equity holders in connection with the THL Transactions and is a joint bookrunner and joint lead arranger under our 2006 senior secured credit facilities. An affiliate of Credit Suisse Securities (USA) LLC is a lender and the administrative agent and collateral agent under the our 2006 senior secured credit facilities.

An affiliate of Banc of America Securities LLC is a lender under our 2006 senior secured credit facilities, and Banc of America Securities LLC is a joint bookrunner and joint lead arranger thereunder.

Prior to this offering, there has been no public market for our common stock. The initial public offering price has been determined by a negotiation between us and the representatives and will not necessarily reflect the market price of our common stock following the offering. The principal factors that were considered in determining the public offering price included:

•: the information presented in this prospectus and otherwise available to the underwriters;
•: the history of and prospects for the industry in which we compete;
•: the ability of our management;
•: the prospects for our future earnings;
•: the present state of our development and current financial condition;
•: the recent market prices of, and the demand for, publicly traded common stock of generally comparable companies; and
•: the general condition of the securities markets at the time of this offering.

We offer no assurances that the initial public offering price will correspond to the price at which our common stock will trade in the public market subsequent to the offering or that an active trading market for our common stock will develop and continue after the offering.

In connection with the offering the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions, and penalty bids and passive market making in accordance with Regulation M under the Securities Exchange Act of 1934.

•: Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.
•: Over-allotment involves sales by the underwriters of shares in excess of the number of shares the underwriters are obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of shares over-allotted by the underwriters is not greater than the number of shares that they may purchase in the over-allotment option. In a naked short position, the number of shares involved is greater than the number of shares in the over-allotment option. The underwriters may close out any covered short position by either exercising their over-allotment option and/or purchasing shares in the open market.
•: Syndicate covering transactions involve purchases of the common stock in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of shares to close out the short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. If the underwriters sell more shares than could be covered by the over-allotment option, a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.
•: Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the common stock originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the common stock. In addition, neither we nor any of the underwriters make any representation that the underwriters will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of the common stock. As a result the price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on The New York Stock Exchange or otherwise and, if commenced, may be discontinued at any time.

A prospectus in electronic format may be made available on the web sites maintained by one or more of the underwriters, or selling group members, if any, participating in this offering and one or more of the underwriters participating in this offering may distribute prospectuses electronically. The representatives may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the underwriters and selling group members that will make internet distributions on the same basis as other allocations.

HAWKEYE HOLDINGS, L.L.C. AND SUBSIDIARY

Notes to Unaudited Condensed Consolidated Financial Statements

March 31, 2005 and 2006

(1) Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of Hawkeye Holdings, LLC and its subsidiary after elimination of intercompany accounts and transactions.

Management has prepared these statements without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission ("SEC"). Certain information and note disclosures normally included in comprehensive financial statements prepared in accordance with accounting principles generally accepted in the United States, have been condensed or omitted pursuant to such rules and regulations of the SEC.

To prepare the financial statements in conformity with accounting principles generally accepted in the United States of America, management has made a number of estimates and assumptions relating to the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

In the opinion of management, the condensed consolidated financial statements reflect all adjustments (which consist only of normal recurring adjustments) necessary to present fairly the Company's financial position as of March 31, 2006, and the results of operations and cash flows for the three-month periods ended March 31, 2005 and 2006. The results of operations for such interim periods are not necessarily indicative of the results for the full year.

The condensed consolidated balance sheet as of December 31, 2005 has been derived from the Company's audited consolidated financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in elsewhere in this prospectus.

(2) Cash, Restricted Cash and Interest Reserve Escrow

The Company maintains its cash accounts at three financial institutions. The Company also maintains various money market accounts that are included in cash and allow for, among other things, funding of the Company's regular monthly operations, continued financing of capital expenditures, and debt service funding.

The Company also maintains an interest reserve escrow account to fund interest payments on the outstanding subordinated notes payable.

Certain of the Company's cash accounts are restricted and may only be used for permitted purposes pursuant to the Company's existing credit facility and to pay interest on the subordinated notes payable. Accordingly, as of December 31, 2005 and March 31, 2006, the Company had restricted cash and escrow balances totalling of $83,914,462 and $53,401,755, respectively.

F-6

(3) Inventories

Inventories are stated at the lower of cost or market (net realizable value). Cost is determined by the first-in, first-out (FIFO) method. At December 31, 2005 and March 31, 2006 inventory consisted of the following:

	December 31, 2005		March 31, 2006
Raw materials	$	1,339,693	$	2,236,543
Work in process		416,259		702,524
Finished goods		424,326		136,272

	$	2,180,278	$	3,075,339

(4) Property, Plant and Equipment

Property, plant and equipment is stated at cost. Plant and equipment under capital leases is stated at the present value of minimum lease payments. Depreciation is computed using the straight-line method over the following estimated useful lives beginning from the date the asset is placed in service:

Office equipment		5 years
Machinery and equipment		7–10 years
Buildings		15–40 years

Plant and equipment held under capital leases is amortized straight line over the shorter of the lease term or estimated useful life of the asset. Amortization of assets held under capital lease is included in depreciation expense.

Maintenance and repairs are expensed as incurred; significant improvements and betterments, which increase the value or materially extend the life of the related assets, are capitalized.

The Company capitalizes interest incurred during the period of construction as part of the cost of the constructed asset. Such costs are amortized over the life of the respective asset. Interest capitalized amounted to $59,675 in the three months ended March 31, 2005 and $1,665,547 in the three months ended March 31, 2006.

At December 31, 2005 and March 31, 2006, accounts payable included $21,813,910 and $19,265,910, respectively, related to the Company's current construction activities. All such amounts are expected to be paid in 2006.

(5) Income Taxes

The Company is treated as a partnership for federal and state income tax purposes, and generally does not incur income taxes. Instead its earnings and losses are included in the income tax returns of its members. Therefore, no provision or liability for federal or state income taxes has been included in these condensed consolidated financial statements.

(6) Miscellaneous Income

Substantially all of the approximately $583,000 and $188,000 of miscellaneous income in the quarters ended March 31, 2005 and 2006, respectively, was derived through a governmental program

F-7

established through the United States Department of Agriculture (USDA) that provides cash payments for companies that generate increases in bioenergy production (ethanol) from previous production levels. Such amounts are recognized when the Company's right to the payment is communicated by the USDA.

(7) Derivative Instruments and Hedging Activities

The Company accounts for derivatives and hedging activities in accordance with Statement of Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative Instruments and Certain Hedging Activities, as amended, which requires that all derivative instruments be recorded on the balance sheet at their respective fair values.

Periodically, the Company uses exchange traded options or futures contracts to reduce its exposure to various commodity market risks. As allowed under the accounting principles generally accepted in the United States of America, the Company has elected not to adopt hedge accounting for any futures contracts that may otherwise qualify for hedge accounting under SFAS 133. Accordingly, any realized or unrealized gain or loss related to these derivative financial instruments is recorded as gain or loss on commodity option transactions in the condensed consolidated statements of operations. The Company realized a net gain of $0 and $850,953 on commodity option transactions for the three months ended March 31, 2005 and 2006, respectively.

The Company uses variable-rate debt to finance its operations. The debt obligations expose the Company to variability in interest payments due to changes in interest rates. Management believes that it is prudent to limit the variability of a portion of its interest payments. To meet this objective, management enters into interest rate swap agreements to manage fluctuations in cash flows resulting from interest rate risk. These swaps change the variable-rate cash flow exposure on the debt obligations to fixed cash flows. Under the terms of the interest rate swaps, the Company receives variable interest rate payments and makes fixed interest rate payments, thereby creating the equivalent of fixed-rate debt.

In 2005 the Company entered into an interest rate swap to minimize the impact of interest rate changes on a portion of its outstanding debt. The swap agreement had not been designated as a hedge for accounting purposes, therefore, all gains or losses are included in interest expense on the condensed consolidated income statement. The fair value of the interest rate swap was $2,062,701 at December 31, 2005 and $3,358,078 at March 31, 2006, respectively.

As part of normal business operations the Company enters into corn purchase contracts with local farmers for bushels of corn to be used in the production of ethanol. The Company has not qualified these contracts for the normal purchase/normal sale exception under SFAS 133, and accordingly has marked these contracts to market as required under SFAS 133 with the change in market value reflected in cost of goods sold. As of December 31, 2005 and 2006, and as of March 31, 2006, the fair value of these contracts was a liability of $585,000 and an asset of $500,000, respectively. Also in the normal course of business operations, the Company enters into sales contracts for the future delivery of ethanol and distilled grains. The Company has concluded that these contracts do not meet the definition of a derivative under SFAS 133 as there is no mechanism for net settlement. These contracts are shown as commitments in note 9.

F-8

(8) Recently Issued Accounting Standards

In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 151, Inventory Costs (SFAS 151), which clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). Under SFAS 151, such items will be recognized as current-period charges. In addition, SFAS 151 requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS 151 was effective for the Company for inventory costs incurred on or after January 1, 2006. The adoption of SFAS 151 did not have a significant effect on the Company's condensed consolidated financial statements.

In May 2005, the FASB issued SFAS No. 154, Accounting Changes and Error Corrections (SFAS 154). SFAS 154 establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transition requirements specific to a newly adopted accounting principle. SFAS 154 is effective for the Company for all accounting changes and any error corrections occurring after January 1, 2006.

In March 2005, the FASB issued FASB Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations (FIN 47), which requires conditional asset retirement obligations to be recognized if a legal obligation exists to perform asset retirement activities and a reasonable estimate of the fair value of the obligation can be made. FIN 47 also provides guidance as to when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. The Company adopted the provisions of FIN 47 on December 31, 2005. No conditional asset retirement obligations were recognized and, accordingly, the adoption of FIN 47 had no effect on the Company's condensed consolidated financial statements.

(9) Commitments and Contingencies

(a) Design Build Contract

The Company has entered into two Design Build Contracts for the expansion of one ethanol facility and the construction of a second new ethanol facility for an aggregate contract price of approximately $128 million. Remaining commitments on these contracts at March 31, 2006 were approximately $29 million. The total cost of the projects, including the construction and start-up expenses, is expected to approximate $155 million.

(b) Consulting Contracts

In October 2003, the Company entered into a management service agreement with an entity affiliated with a member of the Company, effective July 1, 2004, for general management consulting, finance functions, strategic planning and other services as agreed upon. For these services the Company pays an annual management fee of $0.0167 per gallon of ethanol produced payable quarterly in advance. The agreement has no term, but may be terminated by the management service organization at any time with or without cause upon 30 days' notice, or by either party if substantially all of the assets of the Company are sold or upon dissolution of the Company. The Company paid or accrued $187,500 and $243,799 to the member during the three months ended March 31, 2005 and 2006, respectively.

On February 24, 2005, the Company's subsidiary entered into a financial advisory service agreement with an entity affiliated with a member for $12,500 per month. The Company paid or

F-9

accrued $0 and $37,500 to the member during the three months ended March 31, 2005 and 2006, respectively.

On August 11, 2004, the Company entered into a plant operation agreement with an unrelated entity in the business of managing and operating ethanol production facilities, to provide certain services in connection with the production process and operation of the Iowa Falls Plant. The initial term of this agreement is thirty months from the effective date, or through February 11, 2007. Early termination options are available to both parties based on specific facts and circumstances. As part of the agreement, the Company pays an annual management fee of $225,000, payable in advance in equal monthly installments of $18,750. No payments were expensed as management fees during the three months ended March 31, 2005 and payments of $56,250 have been expensed as management fees during the three months ended March 31, 2006.

The Company also pays this entity an annual bonus based upon each gallon of denatured ethanol produced at the plant in excess of a specified number of gallons per year, for each year during the term of the agreement, including any partial years once production begins. This bonus is due and payable quarterly. The Company had not accrued any amount for this bonus at March 31, 2005 and had accrued $73,427 for this bonus at March 31, 2006.

Finally, an additional bonus is available of $40,000, for any and all six-month periods in which the Plant produces a specified number of gallons or more of denatured ethanol during the term of the agreement. The first six-month period shall begin on the date the Plant begins grinding corn for production of ethanol. The Company accrued $20,000 for this bonus at March 31, 2006.

On November 19, 2004, the Company entered into a plant operation agreement with an unrelated entity in the business of managing and operating ethanol production facilities, to provide certain services in connection with the production process and operation of the Fairbank Plant. The initial term of this agreement is thirty months from the effective date, or through May 9, 2007. Early termination options are available to both parties based on specific facts and circumstances. As part of the agreement, the Company pays an annual management fee of $225,000, payable in advance in equal monthly installments of $18,750. No payments have been expensed as management fees during the three months ended March 31, 2005 and payments of $56,250 have been expensed as management fees during the three months ended March 31, 2006.

The Company also pays this entity an annual bonus based upon each gallon of denatured ethanol produced at the plant in excess of a specified number of gallons per year, for each year during the term of the agreement, including any partial years once production begins. This bonus shall be due and payable quarterly. The Company accrued $0 for this bonus at March 31, 2006, as this plant has not yet commenced production.

(c) Purchase Commitments

At March 31, 2006, the Company had outstanding contracts with various vendors to purchase approximately 30,792,980 bushels of corn for delivery in the normal course of business through December 2006. This commitment has a value of approximately $67,225,458 based on published futures prices of corn for the period of delivery.

F-10

(d) Sales Commitments

At March 31, 2006, the Company has commitments to sell approximately 93,578,303 gallons of ethanol to one customer at an average price of $1.99 per gallon for delivery through December 2006 and approximately 123,000 tons of distillers grains to another customer with expected sales of approximately $8,553,000 for delivery through September 2006.

(e) Environmental Liabilities

The Company's operations are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdiction in which it operates. These laws require the Company to investigate and remediate the effects of the release or disposal of material at its locations. Accordingly, the Company has adopted policies, practices, and procedures in the areas of pollution control, occupational health, and the production, handling, storage, and use of hazardous materials to prevent environmental or other damage, and to limit the financial liability which could result from such events. Environmental liabilities are recorded when the Company's liability is probable and the costs can be reasonably estimated. No such liabilities were recorded at December 31, 2005 or March 31, 2006.

(10) Concentration of Credit Risk

All of the Company's sales for the three months ended March 31, 2005 and 2006 and all of the accounts receivable balance outstanding at December 31, 2005 and March 31, 2006 are with two customers.

(11) Segment Information

The Company operates in one business segment, the dry milling of corn to produce ethanol, and therefore does not report operating income (loss), identifiable assets and/or other resources related to business segments. All of the Company's revenues are derived from sales to customers located in the United States.

HAWKEYE HOLDINGS, L.L.C. AND SUBSIDIARY

Notes to Consolidated Financial Statements

December 31, 2004 and 2005

(1) Nature of Business and Significant Accounting Policies

(a) Nature of Business

Hawkeye Holdings, L.L.C., an Iowa Limited Liability Company (Holdings), together with its wholly-owned subsidiary Hawkeye Renewables, LLC, a Delaware Limited Liability Company (Renewables and, together with Holdings, the Company), is a manufacturer primarily engaged in the production and marketing of ethanol. The Company also produces distillers grains, which is a co-product of ethanol production.

Prior to February 22, 2005, the Company was an operating company known as Iowa Falls Ethanol Plant (IFEP). IFEP was established on October 22, 2003, and was a development stage enterprise until November 2004 when it commenced its planned principal operations. On February 22, 2005, substantially all of the assets and liabilities of IFEP were transferred to Renewables, then a newly-formed operating company. IFEP was renamed Hawkeye Holdings, L.L.C. Renewables is a 100% owned consolidated subsidiary of Holdings.

On December 20, 2005, Renewables purchased a majority interest in a newly-formed entity, D&W Railroad, LLC (D&W) in exchange for a cash investment of approximately $1,741,000. The minority interest holder in D&W contributed certain property and rail lines to the venture. D&W owns and maintains rail lines that provide access to facilities owned by its members. The results of operations of D&W are included in the consolidated financial statements from the date of the acquisition.

(b) Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the financial statements of Holdings and its wholly owned subsidiary, Renewables. All significant intercompany balances and transactions have been eliminated in consolidation.

Cash, Restricted Cash and Interest Reserve Escrow

The Company also maintains an interest reserve escrow account to fund interest payments on the outstanding subordinated notes payable.

Certain of the Company's cash accounts are restricted and may only be used for permitted purposes pursuant to the Company's existing credit facility and to pay interest on the subordinated notes payable. Accordingly, as of December 31, 2004 and 2005, the Company had restricted cash and escrow balances totalling $2,002,786 and $83,914,462, respectively.

Receivables

Receivables are carried at the original invoice amount and do not bear interest. The Company periodically evaluates the credit standing of its customers and does not require collateral. Historically

F-17

the Company has not experienced any significant credit losses. As a result, the Company has determined that an allowance for doubtful accounts is not necessary as of December 31, 2004 and 2005.

The Company has two customers. The Company's largest customer accounted for 90.1% and 89.1% of total revenues in 2004 and 2005, respectively. The Company's other customer accounted for 9.9% and 10.9% of total revenues in 2004 and 2005, respectively. Amounts due from these two customers comprised 70.7% and 18.6% of total accounts receivable at December 31, 2005.

Inventories

Inventories are stated at the lower of cost or market (net realizable value). Cost is determined by the first-in, first-out (FIFO) method. At December 31, 2004 and December 31, 2005 inventory consisted of the following:

	December 31,
	2004		2005
Raw materials	$	1,006,480	$	1,339,693
Work in process		334,979		416,259
Finished goods		257,253		424,326

	$	1,598,712	$	2,180,278

Property, Plant and Equipment

Office equipment		5 years
Machinery and equipment		7–10 years
Buildings		15–40 years

Maintenance and repairs are expensed as incurred; significant improvements and betterments, which increase the value or materially extend the life of the related assets, are capitalized.

At December 31, 2004 and 2005, accounts payable included $4,109,002 and $21,813,910, respectively, related to the Company's current construction activities. All such amounts are expected to be paid during 2006.

F-18

Impairment of Long-Lived Assets

In accordance with Statement of Financial Accounting Standards (SFAS) No. 144, Accounting for Impairment or Disposal of Long-Lived Assets, long-lived assets, such as property, plant, and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized equal to the amount by which the carrying amount of the asset exceeds the fair value of the asset. The Company has not recognized any impairments of long lived assets during the period from inception through December 31, 2005.

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets consist of deposits with utility providers and various prepaid expenses.

Debt Issuance Costs

Debt issuance costs are being amortized over the term of the related debt using a straight-line method of amortization that approximates the effective interest method.

Unearned Revenue

In October 2004, the Company entered into an economic development agreement with a local governmental agency. Pursuant to this agreement, the governmental agency provides certain funding to the Company, and the Company is required to fulfill certain obligations which, if not fulfilled, could result in the Company being required to repay some or all of the amounts received under the agreement. On an annual basis during the term of the agreement, the Company must certify whether it has met the requirements of the agreement. At December 31, 2005 the Company believes it is in compliance with the agreement.

Through December 31, 2005, the Company had received payments totaling $1,500,000 under the agreement. The Company recognizes revenue on this agreement on a straight-line basis over the twelve-year life of the agreement. Such revenue is included in miscellaneous income in the consolidated statements of operations. An additional $775,000 is expected to be received under the agreement in installments through December 31, 2007.

Income Taxes

F-19

Revenue Recognition

Miscellaneous Income

Substantially all of the approximately $5.0 million of miscellaneous income recorded in the year ended December 31, 2005 was derived through a governmental program established through the United States Department of Agriculture (USDA) that provides cash payments for companies that generate increases in bioenergy production (ethanol) from previous production levels. Such amounts are recorded when the Company's right to the payment is communicated by the USDA.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America require management to make a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Derivative Instruments and Hedging Activities

The Company accounts for derivatives and hedging activities in accordance with SFAS No. 133, Accounting for Derivative Instruments and Certain Hedging Activities, as amended, which requires that all derivative instruments be recorded on the balance sheet at their respective fair values.

Periodically, the Company uses exchange traded options or futures contracts to reduce its exposure to various commodity market risks. As allowed under accounting principles generally accepted in the United States of America, the Company has elected not to adopt hedge accounting for any futures contracts that may otherwise qualify for hedge accounting under SFAS 133. Accordingly, any realized or unrealized gain or loss related to these derivative financial instruments is recorded as gain or loss on commodity option transactions in the consolidated statements of operations. The Company realized a net loss of $598,986 on commodity option transactions in 2004, and a gain of $48,866 in 2005.

F-20

designated as a hedge for accounting purposes, therefore, all gains or losses are included in interest expense on the consolidated statements of operations.

As part of normal business operations the Company enters into corn purchase contracts with local farmers for bushels of corn to be used in the production of ethanol. The Company has not qualified these contracts for the normal purchase/normal sale exception under SFAS 133, and accordingly has marked them to market as required under SFAS 133, with the change in market value reflected in cost of goods sold. As of December 31, 2004 and 2005, the fair value of these contracts was a liability of $1,018,000 and $585,000, respectively. Also in the normal course of business operations, the Company enters into sales contracts for the future delivery of ethanol and distilled grains. The Company has concluded that these contracts do not meet the definition of a derivative under SFAS 133 as there is no mechanism for net settlement. These contracts are shown as commitments in note 6.

Fair Values of Financial Instruments

Unless otherwise specified, the Company estimates that the reported value of financial instruments approximates their fair value.

Recently Issued Accounting Standards

In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 151, Inventory Costs (SFAS 151), which clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). Under SFAS 151, such items will be recognized as current-period charges. In addition, SFAS 151 requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS 151 will be effective for the Company for inventory costs incurred on or after January 1, 2006. The adoption of SFAS 151 will not have a significant effect on the Company's consolidated financial statements.

In May 2005, the FASB issued SFAS No. 154, Accounting Changes and Error Corrections (SFAS 154). SFAS 154 establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transition requirements specific to a newly adopted accounting principle. SFAS 154 will be effective for the Company for all accounting changes and any error corrections occurring after January 1, 2006.

In March 2005, the FASB issued FASB Interpretation No. 47, Accounting for Conditional AssetRetirement Obligations (FIN 47), which requires conditional asset retirement obligations to be recognized if a legal obligation exists to perform asset retirement activities and a reasonable estimate of the fair value of the obligation can be made. FIN 47 also provides guidance as to when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. The Company adopted the provisions of FIN 47 on December 31, 2005. No conditional asset retirement obligations were recognized and, accordingly, the adoption of FIN 47 had no effect on the Company's consolidated financial statements.

F-21

(2) Notes Payable

Notes payable, including the current portion, amounted to $20,947,137 at December 31, 2004 and $185,000,000 at December 31, 2005.

On February 24, 2005, the Company entered into a $185,000,000 term loan facility to fund the costs of expansion of one ethanol plant and the construction of a second new ethanol plant. The term loan has a seven year term and matures in January 2012. The term loan requires quarterly principal payments starting July 31, 2006. The Company is obligated to apply a portion of the Company's excess cash flow to principal payments in order to meet the schedule of maximum outstanding debt levels. The Company is also subject to various covenants as part of the term loan. At December 31, 2005, the Company was in compliance with these covenants.

The credit facility bears interest at a six-month LIBOR rate plus 2.875% (6.925% at December 31, 2005). The credit facility is secured by substantially all assets and contains prepayment penalties.

In order to minimize the impact of interest rate changes, the Company effectively fixed the interest rate on a notional amount of $136,000,000 of the variable debt at 4.205% by entering into an interest rate swap agreement. Under the terms of an interest rate swap, the Company receives variable interest rate payments and makes fixed interest rate payments, thereby creating the equivalent of fixed-rate debt on that portion of the debt. As the Company has elected to not apply hedge accounting because the interest rate swap is an economic hedge, changes in the fair value of the interest rate swap are recorded as a component of interest expense. Starting in 2007, the notional amount of the swap is reduced quarterly, such that at the end of the swap agreement on July 31, 2010, the notional amount of the swap will be $36,000,000. The fair value of the swap agreement was an asset of $2,062,701 at December 31, 2005, based on the favorable spread between the locked in fixed rate and the applicable variable rates at December 31, 2005.

The following is a summary of annual maturities of this obligation as of December 31, 2005, commencing January 1, 2006 and thereafter:

Year ended December 31:
	2006	$	925,000
	2007		1,850,000
	2008		1,850,000
	2009		1,850,000
	2010		1,850,000
	Thereafter		176,675,000

			185,000,000
Less current portion			925,000

		$	184,075,000

In 2004, the Company had entered into a $22,200,000 construction loan facility to fund construction costs related to its original ethanol plant. At December 31, 2004, a total of $20,947,137, including accrued interest, was drawn on the facility. Borrowings under this facility carried interest at LIBOR plus 375 basis points. The credit facilities were secured by substantially all of the Company's assets, contained various restrictive covenants, and provided for prepayment penalties. In February

F-22

2005, this loan was converted to a $24,230,000 term loan. This term loan was paid off in conjunction with the Company entering into the $185,000,000 term loan on February 24, 2005. In addition, all remaining unamortized debt issuance costs (totaling approximately $1,000,000) associated with the $24,230,000 term loan were written off upon repayment of the loan in 2005.

(3) Subordinated Notes Payable

Subordinated notes payable consist of the following at December 31, 2004 and 2005:

	2004		2005
16% subordinated note payable, due in 2008	$	26,477,448	$	28,102,198
16% subordinated note payable, due in 2008		—		15,784,515
12% subordinated note payable, due in 2010		—		10,736,277

	$	26,477,448	$	54,622,990

The Company has a subordinated note payable at December 31, 2004 and 2005 of $26,477,448 and $28,102,198, respectively, as a result of an agreement dated January 14, 2004. The note is payable to a fund affiliated through common control with a member in Midwest Renewables, LC, a member in the Company. The note bears interest at 16% and the note, along with any unpaid interest is due September 30, 2008. Quarterly interest payments are due in cash at a coupon rate of 10%. The remaining 6% interest is added to the principal balance of the note quarterly. The note contains various covenants, certain prepayment penalties, and becomes mandatorily redeemable upon a change in control of the Company. Upon repayment of the senior indebtedness described in note 2, the Company is obligated to apply a portion of excess cash flow, as defined, to the subordinated note payable. The subordinated note payable is secured by substantially all assets, junior to the senior indebtedness.

On February 24, 2005, the Company entered into two additional subordinated notes payable arrangements.

One subordinated note payable has a December 31, 2005 balance of $15,784,515. The note is payable to a fund affiliated through common control with a member in Midwest Renewables, LC, a member in the Company. The note bears interest at 16% and the note, along with any unpaid interest is due September 30, 2008. Quarterly interest payments are due in cash at a coupon rate of 10%. The remaining 6% interest is added to the principal balance of the note quarterly. The note contains various covenants, certain prepayment penalties, and becomes mandatorily redeemable upon a change in control of the Company. Upon repayment of the senior indebtedness described in note 2, the Company is obligated to apply a portion of its excess cash flow, as defined, to the subordinated note payable. The subordinated note payable is secured by substantially all assets, junior to the senior indebtedness.

A third subordinated note payable has a December 31, 2005 balance of $10,736,277, plus accrued interest of $321,206. The note is payable to a contractor of the Company. The note bears interest at 12%, which is paid quarterly. The note, along with any unpaid interest is due in February 2010. The subordinated note payable is secured by substantially all assets, junior to the senior indebtedness.

F-23

In 2004, an initial deposit of $3,263,000 was made to an interest reserve escrow account, to be used to fund the interest requirements of the initial loan for the first 12 months. At December 31, 2004, the balance in this interest reserve escrow account was $2,002,786. The remaining balance in this account was refunded to the Company in February 2005, as a function of the $185,000,000 refinancing. At that same time, the Company established a new interest escrow with a $10,900,000 deposit, which is used to fund the cash portion of interest payments on the outstanding 16% subordinated notes payable. At December 31, 2005, the remaining balance in this interest reserve escrow account was $7,030,364.

(4) Capital Lease

The Company is obligated under three capital leases covering certain machinery and equipment that expire at various times through 2008. At December 31, 2005 the gross amount of machinery and equipment recorded under the capital leases was $463,387.

(5) Members' Equity

Holdings was formed on October 22, 2003 to have a perpetual life. Holdings was initially capitalized by one member who contributed $3,000,000 for 13,000,000 Founder Units and by additional members who contributed an aggregate of $10,500,000 for 7,000,000 Additional Member units.

For the period ending December 31, 2003, all loss was allocated to the Founding Member. For the period ending December 31, 2004, income and losses were allocated among the members based upon their respective capital contributions, except that, solely for purposes of calculating the percentage, the capital contributions of the Founding Member are multiplied by 1.5. For the period ending December 31, 2005 and thereafter, income and losses are allocated among the members pro rata based upon their respective member units.

As specified in Holdings' operating agreement, Holdings has two classes of membership units. Founding Member units were issued upon the initial capitalization of the entity; all other units issued

F-24

will be Additional Member Units. The entity was authorized to issue up to 13,000,000 Founding Member Units and does not have a limitation on the number of Additional Member Units that can be issued. No additional units may be issued without the approval of the holders of at least two-thirds of the issued and outstanding Founding Member Units and of the holders of at least two-thirds of the issued and outstanding Additional Member Units. Founding Member and Additional Member Units have equal rights related to matters within their respective classes.

(6) Commitments and Contingencies

(a): Design Build Contract

The Company has entered into two Design Build Contracts for the expansion of one ethanol facility and the construction of a second new ethanol facility for an aggregate contract price of approximately $128 million. Remaining commitments on these contracts at December 31, 2005 were approximately $61 million. The total cost of the projects, including the construction and start-up expenses, is expected to be approximately $155 million.

(b): Consulting Contracts

In October 2003, the Company entered into a management service agreement with an entity affiliated with a member of the Company, effective July 1, 2004 for general management consulting, finance functions, strategic planning and other services as agreed upon. For these services the Company pays an annual management fee of $0.0167 per gallon of ethanol produced payable quarterly in advance commencing July 2004. The agreement has no term, but may be terminated by the management service organization at any time with or without cause upon 30 days' notice, or by either party if substantially all of the assets of the Company are sold or upon dissolution of the Company. The Company paid or accrued $375,000 and $818,111 to the member during the years ended December 31, 2004 and 2005.

On February 24, 2005, the Company's subsidiary entered into a financial advisory service agreement with an entity affiliated with a member for $12,500 per month. The Company paid or accrued $112,500 to the member during the year ended December 31, 2005.

On August 11, 2004, the Company entered into a plant operation agreement with an unrelated entity in the business of managing and operating ethanol production facilities, to provide certain services in connection with the production process and operation of the Iowa Falls Plant. The initial term of this agreement is thirty months from the effective date, or through February 11, 2007. Early termination options are available to both parties based on specific facts and circumstances. As part of the agreement, the Company pays an annual management fee of $225,000, payable in advance in equal monthly installments of $14,583. Payments of $82,796 and $160,687 have been expensed as management fees during the years ended December 31, 2004 and 2005, respectively.

F-25

This bonus is due and payable quarterly. The Company had not accrued any amount for this bonus at December 31, 2004 and had accrued $49,523 for this bonus at December 31, 2005.

Finally, an additional bonus is available of $40,000, for any and all six-month periods in which the Plant produces a specified number of gallons or more of denatured ethanol during the term of the agreement. The first six-month period commenced on the date the plant began grinding corn for production of ethanol. The Company had not accrued any amount for this bonus at December 31, 2004 and had accrued $46,667 for this bonus at December 31, 2005.

The Company also pays this entity an annual bonus based upon each gallon of denatured ethanol produced at the plant in excess of a specified number of gallons per year, for each year during the term of the agreement, including any partial years once production begins. This bonus shall be due and payable quarterly. The Company accrued $0 for this bonus at December 31, 2005, as this plant has not yet commenced production.

(c): Purchase Commitments

At December 31, 2005, the Company had outstanding contracts with various vendors to purchase approximately 5,072,000 bushels of corn for delivery through November 2006.

(d): Sales Commitments

At December 31, 2005, the Company has commitments to sell approximately 91,602,000 gallons of ethanol to one customer at an average price of $1.75 per gallon for delivery through December 2006 and approximately 70,000 tons of distillers grains to another customer with expected sales of approximately $4,720,000 for delivery through September 2006.

(e): Environmental Liabilities

F-26

Company's liability is probable and the costs can be reasonably estimated. No such liabilities were recorded at December 31, 2004 or 2005.

(7) Customer Concentration

Item 14. Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify directors and officers, as well as other employees and individuals, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent to the Registrant. The Delaware General Corporation Law provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any certificate of incorporation, bylaws, agreement, vote of stockholders or disinterested directors or otherwise. The Registrant's certificate of incorporation provides for indemnification by the Registrant of its directors, officers and employees to the fullest extent permitted by the Delaware General Corporation Law.

Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions, or (iv) for any transactions from which the director derived an improper personal benefit. The Registrant's certificate of incorporation provides for such limitation of liability.

The Registrant intends to obtain standard policies of insurance under which coverage will be provided (i) to its directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act, and (ii) to the Registrant with respect to payments which may be made by the Registrant to such directors and officers pursuant to the above indemnification provision or otherwise as a matter of law.

Item 17. Undertakings

The undersigned Registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreements certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

II-3

The undersigned Registrant hereby undertakes that:

(1): For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.
(2): For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
