Previous wording

Our primary market focus, given current demand and growing customer interest, is hydrocarbon fuels, and SAF in particular. We believe that SAF from carbohydrates to alcohol is the most economically viable approach for carbon abatement. We also have commercial opportunities for other renewable hydrocarbon products, such as RNG; hydrocarbons for gasoline blendstocks and diesel fuel; ingredients for the chemical industry, such as ethylene and butenes; plastics and materials; and other chemicals. Global fuel consumption by commercial airlines continues to remain strong, with global fuel consumption of more than 100 MGPY and growing.

Current wording

Our primary market focus, given the large demand and growing customer interest, is net zero hydrocarbon fuels, including SAF. We believe that SAF produced from a carbohydrate-to-alcohol process is the most economically viable approach to generate value from carbon abatement. We also have commercial opportunities for other renewable hydrocarbon products, such as RNG; hydrocarbons for gasoline and racing fuel blendstocks and diesel fuel; ingredients for the chemical industry, such as ethylene and butenes for plastics and materials; and other chemicals.

Previous wording

We are focused on transforming renewable energy into energy-dense liquid hydrocarbons that can be used as renewable fuels, such as sustainable aviation fuel (“SAF”), with the potential to achieve a “net-zero” greenhouse gas (“GHG”) footprint. We believe that this addresses the global need of reducing GHG emissions with “drop in” sustainable alternatives to petroleum fuels. We use the Argonne National Laboratory’s Greenhouse gases, Regulated Emissions, and Energy use in Transportation model (the “GREET Model”) to measure, predict and verify GHG emissions across the life cycle of our products. The “net-zero” concept means Gevo expects that by using sustainably grown feedstock (e.g., low till, no-till and dry corn cultivation), renewable and substantially decarbonized energy sources, drop-in hydrocarbon fuels can be produced that have a net-zero, full life cycle footprint measured from the capture of renewable carbon through the burning of the fuel.

Current wording

To serve these markets, we are developing commercial projects for converting renewable energy into energy-dense, liquid hydrocarbons that can be used as renewable fuels, such as SAF, with the potential to achieve a cost competitive “net zero” greenhouse gas (“GHG”) footprint. We believe that this addresses the global need of economically reducing GHG emissions with “drop in” sustainable alternatives to petroleum fuels. We use the Argonne National Laboratory’s Greenhouse gases, Regulated Emissions, and Energy use in Transportation model (the “GREET Model”) to measure, predict and verify GHG emissions across the life cycle of our products. The “net zero” concept means Gevo expects that by using sustainably grown feedstock (e.g., low till, no-till cultivation) and renewable and substantially decarbonized energy sources, drop-in hydrocarbon fuels can be produced that have a net zero, full life cycle footprint measured from the capture of renewable carbon through the burning of the fuel. This is because such feedstocks come from crops, which take carbon dioxide out of the atmosphere and convert it into biomass through photosynthesis. This yields vital amino acid nutrients, or protein, that humans and animals can consume, as well as vegetable oil and carbohydrates, or sugar. The plant sugar may be fermented with microorganisms to produce a clean alcohol suitable for industrial scale chemical processing into hydrocarbons. Given the overabundance of plant-derived sugar, the growing unmet demand for drop-in, renewable hydrocarbons such as SAF, and the availability of demonstrated industrial-scale technologies that can convert plant sugars to alcohols and then to hydrocarbons, we view our project as first movers in an attractive, scalable new industry connecting this overabundance of plant sugar to unmet demand for products such as SAF.

Net-Zero Projects. Our concept of “Net-Zero Projects” is a series of planned facilities to produce energy dense liquid hydrocarbons using renewable energy and our proprietary technology. Our initial Net-Zero Project, Net-Zero 1 (“NZ1”), is expected to be located in Lake Preston, South Dakota, and is being currently designed to produce approximately 65 million gallons per year (“MGPY”) of total hydrocarbon volumes, including 60 MGPY of SAF, which would fulfill part of our approximately 350 MGPY of SAF and hydrocarbon supply agreements. The liquid hydrocarbons, when burned, are expected to have a “net-zero” GHG footprint. Along with the hydrocarbons, NZ1 is expected to produce approximately 695,000 tons per year of high-value protein products for use in the food chain and more than 34 million pounds per year of corn oil. Our products will be produced in three steps: the first step is milling the corn to produce the carbohydrates needed for the production of SAF while simultaneously enabling the production of protein and oil; the second step produces alcohols using carbohydrate-based fermentation; and the third step is the conversion of the alcohols into hydrocarbons.

Current wording

Alcohol-to-Jet Projects. Our concept of “Alcohol-to-Jet Projects” is a series of planned facilities to produce energy dense liquid hydrocarbons using renewable energy and our proprietary technology. Our initial Alcohol-to-Jet Project, which we refer to as “ATJ-60”, is expected to be located in Lake Preston, South Dakota, and is being designed to produce approximately 65 million gallons per year (“MGPY”) of total hydrocarbon volumes, including 60 MGPY of SAF. The liquid hydrocarbons, when burned, are expected to have a “net zero” GHG footprint. Along with the hydrocarbons, ATJ-60 is expected to produce approximately 1.3 billion pounds per year of high-value protein products for use in the food chain and approximately 30 million pounds per year of corn oil. Our products will be produced in three steps: the first step is milling the corn to produce the carbohydrates needed for the production of SAF while simultaneously enabling the production of protein and oil; the second step produces alcohols using carbohydrate-based fermentation; and the third step is the conversion of the alcohols into hydrocarbons.

We work with several technology, design and equipment partners, most notably Fluid Quip Technologies (FQT), Axens, and Praj. FQT and Axens provide area operation designs which have been incorporated into Gevo’s proprietary overall design of low CI carbohydrate-to-hydrocarbon plants, such as NZ1 plant. Praj is working with us on the proprietary design and construction of prefabricated process modules for our plants. Our partners are working with us on proprietary process designs that have the potential to lower capital and operating cost in the future. The advantage of utilizing Fluid Quip and Axens area operation and related process designs which are well proven in other applications, we believe we have chosen technology which is substantially de-risked.

Previous wording

We have substantially completed the engineering design of NZ1. We have substantially completed value engineering and we are now focusing on detail engineering with an EPC partner, to reduce and contractually finalize a negotiated lump-sum, fixed price agreement whereby the EPC will build and deliver the plant. This detail engineering work is focused specifically on increasing the modularization of component parts on the NZ1 plant design, which means that we expect that the process equipment would be built into modules at a factory, then the modules would be assembled onsite at NZ1, with the goal of minimizing specialized field work typical in plant construction of this type. This approach is expected to lower the risk and cost of, and access to, skilled labor at the site and reduce the supply chain constrictions for some of our long-lead equipment. Increasing the modularization of the plant design is also expected to reduce our spend in advance of securing third-party equity and debt financing for NZ1 and increase the certainty of construction schedule for those counterparties.

Current wording

We have substantially completed the engineering design on our ATJ-60 project and are proceeding with detailed engineering and modularization design. We are refining the project cost estimates with engineering, procurement, and construction (“EPC”) partners to identify opportunities to reduce and negotiate the cost. After which, we expect to sign a lump-sum, fixed price agreement for the EPC to build and deliver the plant. The current detailed engineering work is focused on increasing the modularization of component parts on the ATJ-60 plant design, with the goal to build the process equipment into modules at a factory, then assemble onsite. This will enable us to minimize specialized field work typical in plant construction of this type, lower the risk and costs, as well as provide better access to skilled labor.

Previous wording

We completed the value engineering on our NZ1 project and are proceeding with detailed engineering, modularization design, and capital costs updates. We are currently refining project cost estimates with engineering, procurement, and construction (“EPC”) partners to identify cost saving opportunities, and currently expect to finance the construction of NZ1 at the subsidiary level using a combination of Company equity and third-party capital, to include non-recourse debt. The Company expects to have invested a cumulative total of $236 to $286 million of cash equity in the project at financial close. Cash distributions from future NZ1 earnings would be proportionate to Gevo’s ownership in NZ1 under this expected financing structure. The use of project debt and third party equity allows us to conserve capital for use on other growth projects. We expect to apply similar development and financing strategies to future Net-Zero Projects to enable growth of SAF production to meet demand for SAF.

Current wording

We currently expect to finance the construction of ATJ-60 at the subsidiary level using a combination of Company equity, third-party capital, and non-recourse debt. The Company previously projected a range of $90.0 – $125.0 million to be spent on ATJ-60 between January 2024 and the financial close of ATJ-60. Year to date 2024, the Company expects the remaining spend until the financial close of ATJ-60 to fall below the previously estimated range. Cash distributions from future ATJ-60 earnings would be proportionate to Gevo’s ownership in ATJ-60 under this expected financing structure. The use of project debt and third-party equity allows us to conserve capital for use on other growth projects. We expect to apply similar development and financing strategies to future Alcohol-to-Jet Projects to grow our SAF production to meet the demand for SAF.

We are evaluating and performing early site development work at several sites in the U.S. for other greenfield sites. These sites include several greenfield locations that are particularly advantageous in terms of potential economics, opportunities to decarbonize, and time to market. In addition, we are pursuing potential Net-Zero Projects with several existing ethanol plant sites. Existing ethanol plants need to be decarbonized with renewable energy or de-fossilized energy and/or carbon sequestration. Gevo has developed a preferred list of potential partners and sites with decarbonization in mind and is engaged in preliminary feasibility and development discussions with several of these potential partners. We plan to give priority to existing industrial plant sites that have attractive potential economics and high predictability of timeline for decarbonization.

Verity. It is critical that we can prove the CI of our products, ensuring that these values are accurate and auditable. The mission of Verity (“Verity”), including Verity Tracking and Verity Carbon Solutions, is to document CI and other sustainability attributes and apply Distributed Ledger Technology, commonly referred to as blockchain, to create a record of the products throughout the entire business system. Verity starts by calculating carbon intensity of feedstocks from data collected at the farm and field level. We plan to track these feedstocks through production at our plants where we intend to use a mix of renewable electricity, biogas, renewable hydrogen and other potentially decarbonized energy sources in production. The CI data would then be combined to deliver a comprehensive CI reduction in a finished renewable fuel. The resulting CI reduction value has potential to be quantified as a digital asset and monetized in voluntary or compliance carbon markets, and providing compliance needs for tax incentives while preventing double-counting. We believe that in the future, regenerative agricultural practices have the potential to sequester large quantities of soil organic carbon while improving soil health.

There is increasing regulatory and stakeholder pressure on global corporations to lower emissions. These trends are driving demand for carbon credits, giving rise to two sets of markets, the regulated compliance carbon market and the unregulated voluntary carbon market, both of which could grow meaningfully in the coming decades. The total value of major compliance carbon markets is expected to be greater than $800 billion in 2023, according to Bloomberg. Verity intends to document and account for carbon capture in conjunction with scientifically supported measurement techniques. The potential for Verity is broad and could be applicable to tracking the CI of various items beyond Gevo’s internal businesses, including, but not limited to, renewable fuels, food, feed and industrial products through their respective business systems and value chains. Our robust scientific measurement, reporting, and verification plan and approach is expected to provide a high-quality credit that should meet regulated compliance and unregulated carbon markets.

Previous wording

Since our inception in 2005, we have devoted most of our cash resources to the development and commercialization of routes to efficiently produce fuels and chemicals from carbohydrates, such as renewable feedstock, using alcohols (isobutanol and ethanol) as intermediates. We have incurred losses since inception, have a significant accumulated deficit, and expect to incur losses for the foreseeable future. Historically we have financed our operations primarily with proceeds from the issuance of equity, warrants, debt securities, and borrowings under debt facilities. Our current sources of cash include sales of RNG, environmental attributes, and licensing fees. We may also fund future operations through additional private and/or public offerings of equity or debt securities. In addition, we may seek additional capital, on acceptable terms, through arrangements with strategic partners or from other sources. Notwithstanding, there can be no assurance that we will be able to raise additional funds or achieve or sustain profitability or positive cash flows from operations.

Previous wording

Our transition to profitability is dependent upon, among other things, the successful development and commercialization of our product candidates, the development, licensing, acquisition and construction of commercial level production facilities to support our offtake agreements, the achievement of a level of revenues adequate to support the Company’s cost structure, and the ability to raise capital to finance the development, licensing, acquisition, and construction of additional productions facilities.

During the year ended December 31, 2023, net cash used in operating activities was $53.7 million compared to $44.3 million for the year ended December 31, 2022. Non-cash charges primarily consisted of depreciation and amortization of $19.0 million, stock-based compensation expense of $17.1 million, which reflects higher amortization expense for the stock awards issued in the prior period with higher market value, see Note 16 to the Consolidated Financial Statements for additional information, and non-cash expense of $0.1 million related to the amortization of marketable securities premiums. The net cash outflow from changes in operating assets and liabilities increased $23.9 million, primarily due to an increase in cash outflows of $23.0 million related toprepaid expenses and other current assets, deposits and other assets, $2.6 million related to increases in accounts receivable as well as $0.9 million related to accounts payable and accrued liabilities. These were partially offset by $2.7 millionof decreased costs associated with the sale of environmental attribute inventory.

Non-cash charges primarily consisted of stock-based compensation expense of $14.7 million and depreciation and amortization of $18.3 million. The net cash outflow from changes in operating assets and liabilities decreased $10.1 million, primarily due to a decrease in cash outflows of $6.6 million related toprepaid expenses and other current assets, deposits and other assets, $2.6 million related to increases in accounts receivable as well as $2.4 million related to accounts payable and accrued liabilities. These were partially offset by $1.4 millionof increased costs associated with the sale of environmental attribute inventory.

Previous wording

We completed the value engineering on our NZ1 project and are proceeding with detailed engineering, modularization design, and capital costs updates. We are currently refining project cost estimates with engineering, procurement, and construction (“EPC”) partners to identify cost saving opportunities, and currently expect to finance the construction of NZ1 at the subsidiary level using a combination of Company equity and third-party capital, to include non-recourse debt. The Company expects to have invested a cumulative total of $236 to $286 million of cash equity in the project at financial close. Cash distributions from future NZ1 earnings would be proportionate to Gevo’s ownership in NZ1 under this expected financing structure. The use of project debt and third party equity allows us to conserve capital for use on other growth projects. We expect to apply similar development and financing strategies to future Net-Zero Projects to enable growth of SAF production to meet demand for SAF.

Current wording

We have substantially completed the engineering design on our ATJ-60 project and are proceeding with detailed engineering and modularization design. We are refining the project cost estimates with EPC partners to identify opportunities to reduce and negotiate the cost. We currently expect to finance the construction of ATJ-60 at the subsidiary level using a combination of Company equity and third-party capital, to include non-recourse debt. The Company previously projected a range of $90.0 – $125.0 million to be spent on ATJ-60 between January 2024 and the financial close of ATJ-60. Year to date 2024, the Company expects the remaining spend until the financial close of ATJ-60 to fall below the previously estimated range. Cash distributions from future ATJ-60 earnings would be proportionate to Gevo’s ownership in ATJ-60 under this expected financing structure.

Previous wording

In 2022, we allocated approximately $25.0 million to develop our next Net-Zero Project, of which we have spent approximately $15.0 million. Gevo is in the process of identifying and performing early site development work for additional Net-Zero production locations. These potential sites include greenfield and brownfield (i.e., at an existing ethanol plant) locations that are advantageous in terms of potential economics, opportunities to decarbonize, and time to market.

Previous wording

We currently expect to finance the construction of NZ1 at the subsidiary level using a combination of our own, third-party, and debt capital. The Company expects to retain an equity interest in the project and may invest equity in the project using the proceeds from the reimbursement of the Company’s NZ1 development expenditures. Cash distributions from future NZ1 earnings would be proportionate to Gevo’s ownership in NZ1 under this expected financing structure which would allow us to conserve and redeploy our capital on other growth projects, including our Net-Zero 2 project (“NZ2”). We expect to apply similar development and financing strategies to NZ2 and future Net-Zero Projects to enable growth of SAF production to meet demand for SAF.

Our Consolidated Financial Statements are based on the application of U.S. GAAP, which requires us to make estimates and assumptions about future events that affect the amounts reported in our Consolidated Financial Statements and the accompanying notes. Future events and their effects cannot be determined with certainty; therefore, the determination of estimates requires the exercise of judgment. We believe our judgments related to these accounting estimates are appropriate. However, if different assumptions or conditions were to prevail, the results could be materially different from the amounts recorded. We have determined that we have no critical accounting estimates material to our consolidated financial position, results of operations or cash flow related to our consolidated financial statements included in this Report.
