RISK FACTORS

Investing in our common stock involves a high degree of risk. Before purchasing our common stock, you should read and consider carefully the following risk factors as well as all other information contained and incorporated by reference in this prospectus supplement and the accompanying base prospectus, including our consolidated financial statements and the related notes. Each of these risk factors, either alone or taken together, could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our common stock. There may be additional risks that we do not presently know of or that we currently believe are immaterial, which could also impair our business and financial position. If any of the events described below were to occur, our financial condition, our ability to access capital resources, our results of operations and/or our future growth prospects could be materially and adversely affected and the market price of our common stock could decline. As a result, you could lose some or all of any investment you may make in our common stock.

Risks Relating to Our Business

We need access to additional financing in 2019 and beyond, which may not be available to us on acceptable terms or at all. If we cannot access additional financing when we need it and on acceptable terms, our business may fail.

Our business plan to design, produce, sell and service commercial electric vehicles through our Union City facility will require continued capital investment in 2019. Our research and development activities will also require continued investment. For the year ended December 31, 2018, our independent registered public accounting firm issued a report on our 2018 financial statements that contained an explanatory paragraph stating that the lack of sales, negative working capital and stockholders’ deficit, raise substantial doubt about our ability to continue as a going concern. Among other things, even with the addition of the expected proceeds of this offering, unless we obtain additional financing, we will not have sufficient capital recourses to fund our operations beyond the first half of 2019 or to maintain compliance with certain covenants under the Marathon Agreement. In addition, although the Marathon Agreement provides us access to some funds to produce vehicles for which we have received confirmed purchase orders, we will not be able to produce the N-GEN vehicles for which we currently have confirmed purchase orders unless we obtain approximately $22 million in financing in addition to the proceeds of this offering and what is expected to be available under the Marathon Agreement. Unless and until we are able to generate a sufficient amount of revenue, reduce our costs and/or enter a strategic relationship, we expect to finance future cash needs through public and/or private offerings of equity securities and/or debt financings. More generally, as discussed above, we have committed debt funding through the Marathon Agreement to support inventory purchases for confirmed customer purchase orders, but do not currently have any committed future funding for other operating costs. If we are not able to obtain additional financing and/or substantially increase revenue from sales, we will be unable to continue as a going concern. As a result, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our consolidated financial statements, and investors will likely lose a substantial part or all of their investment. We cannot be certain that additional financing will be available to us on favorable terms when required, or at all. Further, if there remains doubt about our ability to continue as a going concern, investors or other financing sources may be unwilling to provide additional funding on acceptable terms or at all. If we cannot obtain additional financing when we need it and on terms acceptable to us, we will not be able to continue as a going concern. Any additional financing may be made at a price per share below the price at which the shares of common stock are sold in this offering and would result in dilution to the investors in this offering.

Our results of operations have not resulted in profitability and we may not be able to achieve profitability going forward.

We have an accumulated deficit of $141.6 million for the period from inception (February 20, 2007) through December 31, 2018. We have had net losses in each quarter since our inception. We expect that we will continue to incur net losses in the first part of 2019. We may incur significant losses in the future for a number of reasons, including the other risks described in this prospectus, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown events. Accordingly, we may not be able to achieve or maintain profitability. Our management is developing plans to alleviate the negative trends and conditions described above and there is no guarantee that such plans will be successfully implemented. Our business plan is focused on providing sustainable and cost-effective solutions to the commercial transportation sector but is still unproven. There is no assurance that even if we successfully implement our business plan, that we will be able to curtail our losses or ever achieve profitable operations. If we incur additional significant operating losses, our stock price may significantly decline.

We have yet to achieve positive cash flow and, given our projected funding needs, our ability to generate positive cash flow is uncertain.

We have had negative cash flow from operating activities of $21.8 million and $38.7 million for the years ended December 31, 2018 and 2017, respectively. We anticipate that we will continue to have negative cash flow from operating and investing activities in the first part of 2019 as we expect to incur research and development, sales and marketing, and general and administrative expenses and make modest capital expenditures in our efforts to increase sales and ramp up operations at our Union City facility. Our business also will at times require significant amounts of working capital to support our growth of additional platforms. An inability to generate positive cash flow for the near term may adversely affect our ability to raise needed capital for our business on reasonable terms, diminish supplier or customer willingness to enter into transactions with us, and have other adverse effects that may decrease our long-term viability. There can be no assurance that the Company will achieve positive cash flow in the near future or at all.

The development of our business in the near future is contingent upon the implementation of orders from UPS and other key customers for the purchase of Workhorse vehicles and if we are unable to perform under these orders, our business may fail.

On June 4, 2014, the Company entered into a Vehicle Purchase Agreement with United Parcel Service Inc. (“UPS”) which outlined the relationship by which the Company would sell vehicles to UPS. To date, we have received six separate orders totaling up to 1,405 vehicles from UPS. The sixth and most recent order is from Q1 2018. We have entered into various purchase orders with UPS relating to the delivery of certain vehicles ordered. The vehicles subject to these purchase orders were originally required to be delivered in Q1 2019; we currently expect to begin delivering them in Q4 2019, subject to our ability to obtain additional financing to fund their production. There is no guarantee that the Company will be able to perform under these orders and if it does perform, that UPS will purchase additional vehicles from the Company. Also, there is no assurance that UPS will not terminate its agreement with the Company pursuant to the termination provisions therein. Further, if the Company is not able to raise the required capital to purchase required parts and pay certain vendors, the Company may not be able to comply with UPS’s deadlines. Accordingly, despite the receipt of the orders from UPS, there is no assurance, due to the Company’s financial constraints and status as a development stage company, that the Company will be able to deliver such vehicles or that it will receive additional orders whether from UPS or other potential customers.

If we are unable to perform under our orders with UPS, the Company business will be significantly negatively impacted.

Our limited operating history makes it difficult for us to evaluate our future business prospects and make decisions based on those estimates of our future performance.

As we begin to fully implement our manufacturing capabilities, it is difficult, if not impossible, to forecast our future results based upon our historical data. Because of the uncertainties related to our lack of historical operations, we may be hindered in our ability to anticipate and adapt to increases or decreases in revenues or expenses. If we make poor budgetary decisions as a result of unreliable historical data, we could be less profitable or incur losses, which may result in a decline in our stock price.

Our obligations to Marathon, which holds a secured loan, are secured by a security interest in substantially all of our assets, so if we default on those obligations, Marathon could foreclose on, liquidate and/or take possession of our assets. If that were to happen, we could be forced to curtail, or even to cease, our operations.

All amounts due under the loan payable to Marathon are secured by our assets. As a result, if we default on our obligations under the secured loan, Marathon could foreclose on its security interest and liquidate or take possession of some or all of these assets, which would harm our business, financial condition and results of operations and could require us to curtail, or even to cease our operations.

We are subject to certain covenants set forth in the Marathon Agreement. Upon an event of default, including a breach of a covenant or the failure to obtain shareholder approval to increase our authorized shares of common stock, we may not be able to make such accelerated payments under the Marathon Agreement.

The Marathon Agreement contains customary events of default, including for non-payment, misrepresentation, breach of covenants, defaults under other material indebtedness, material adverse change, bankruptcy, change of control and material judgments. Among other things, we will be required to maintain a minimum liquidity of at least $4.0 million at all times after April 30, 2019. We do not expect that we will be able to maintain compliance with this covenant unless we obtain further financing in addition to the proceeds of this offering. Additionally, failure to obtain shareholder approval to increase the number of authorized shares of our common stock would constitute an Event of Default under the Marathon Agreement.

The Loans mature on the third anniversary of the closing date. The Company is required to repay a portion of the Tranche One Loans with $500,000 installment payments on each of June 30, 2020, December 31, 2020 and June 30, 2021. Upon the occurrence and during the continuance of an event of default, the Lenders may declare all outstanding amounts thereunder immediately due and payable and may terminate commitments to make any additional advances under the Tranche Two Loans. Upon an event of default, the outstanding principal amount of the loan plus any other amounts owed to Marathon will become immediately due and payable and Marathon could foreclose on our assets. A default would also likely significantly diminish the market price of our common stock.

We offer no financing on our vehicles. As such, our business is dependent on cash sales, which may adversely affect our growth prospects.

While most of our current customers are well-established companies with significant purchasing power, many of our potential smaller and medium-sized customers may need to rely on credit or leasing arrangements to gain access to our vehicles. Unlike some of our competitors who provide credit or leasing services for the purchase of their vehicles, we do not provide, and currently do not have commercial arrangements with a third party that provides, such financial services. We believe the current limited availability of credit or leasing solutions for our vehicles could adversely affect our revenues and market share in the commercial electric vehicle market.

We do not receive progress payments on orders of our vehicles, and if a purchaser fails to pay upon delivery, we may not be able to recoup the costs we incurred in producing such vehicles.

Our arrangements with existing customers do not provide for progress payments as we begin to fulfill orders.  Customers are only required to pay us upon delivery of vehicles.  If a customer fails to take delivery of an ordered vehicle or fails to pay for such vehicle, we may not receive cash to offset the production expenses of such vehicle, which could adversely affect our cash flows.

Our business, prospects, financial condition and operating results will be adversely affected if we cannot reduce and adequately control the costs and expenses associated with operating our business, including our material and production costs.

We incur significant costs and expenses related to procuring the materials, components and services required to develop and produce our electric vehicles. We have secured supply agreements for our critical components including our batteries. However, these are dependent on volume to ensure that they are available at a competitive price. We continually work on cost-down initiatives to reduce our cost structure so that we may effectively compete. If we do not reduce our costs and expenses, our net losses will continue which will negatively impact our business and stock price.

Increases in costs, disruption of supply or shortage of lithium-ion cells could harm our business.

We may experience increases in the cost or a sustained interruption in the supply or shortage of lithium-ion cells. Any such increase, supply interruption or shortage could materially and negatively impact our business, prospects, financial condition and operating results. The prices for these lithium-ion cells can fluctuate depending on market conditions and global demand for these materials and could adversely affect our business and operating results. We are exposed to multiple risks relating to lithium-ion cells including:

Our business is dependent on the continued supply of battery cells for the battery packs used in our vehicles. While we believe several sources of the battery cells are available for such battery cells, we have fully qualified only Panasonic for the supply of the cells used in such battery packs and have very limited flexibility in changing cell suppliers. Any disruption in the supply of battery cells could disrupt production of our vehicles until such time as a different supplier is fully qualified. Furthermore, fluctuations or shortages in petroleum, tariff or trade issues and other economic or tax conditions may cause us to experience significant increases in freight charges. Substantial increases in the prices for the battery cells or prices charged to us, would increase our operating costs, and could reduce our margins if we cannot recoup the increased costs through increased vehicle prices. Any attempts to increase vehicle prices in response to increased costs in our battery cells could result in cancellations of vehicle orders and therefore materially and adversely affect our brand, image, business, prospects and operating results.

The demand for commercial electric vehicles depends, in part, on the continuation of current trends resulting from dependence on fossil fuels. Extended periods of low diesel or other petroleum-based fuel prices could adversely affect demand for our vehicles, which would adversely affect our business, prospects, financial condition and operating results.

We believe that much of the present and projected demand for commercial electric vehicles results from concerns about volatility in the cost of petroleum-based fuel, the dependency of the United States on oil from unstable or hostile countries, government regulations and economic incentives promoting fuel efficiency and alternative forms of energy, as well as the belief that climate change results in part from the burning of fossil fuels. If the cost of petroleum-based fuel decreased significantly, the outlook for the long-term supply of oil to the United States improved, the government eliminated or modified its regulations or economic incentives related to fuel efficiency and alternative forms of energy, or if there is a change in the perception that the burning of fossil fuels negatively impacts the environment, the demand for commercial electric vehicles could be reduced, and our business and revenue may be harmed.

Diesel and other petroleum-based fuel prices have been extremely volatile, and we believe this continuing volatility will persist. Lower diesel or other petroleum-based fuel prices over extended periods of time may lower the perception in government and the private sector that cheaper, more readily available energy alternatives should be developed and produced. If diesel or other petroleum-based fuel prices remain at deflated levels for extended periods of time, the demand for commercial electric vehicles may decrease, which would have an adverse effect on our business, prospects, financial condition and operating results.

Our future growth is dependent upon the willingness of operators of commercial vehicle fleets to adopt electric vehicles and on our ability to produce, sell and service vehicles that meet their needs. This often depends upon the cost for an operator adopting electric vehicle technology as compared to the cost of traditional internal combustion technology.

Our growth is dependent upon the adoption of electric vehicles by operators of commercial vehicle fleets and on our ability to produce, sell and service vehicles that meet their needs. The entry of commercial electric vehicles into the medium-duty commercial vehicle market is a relatively new development, particularly in the United States, and is characterized by rapidly changing technologies and evolving government regulation, industry standards and customer views of the merits of using electric vehicles in their businesses. This process has been slow as without including the impact of government or other subsidies and incentives, the purchase prices for our commercial electric vehicles currently is higher than the purchase prices for diesel-fueled vehicles. Our growth has also been negatively impacted by the relatively low price of oil over the last few years.

If the market for commercial electric vehicles does not develop as we expect or develops more slowly than we expect, our business, prospects, financial condition and operating results will be adversely affected.

As part of our sales efforts, we must educate fleet managers as to the economical savings we believe they will benefit from during the life of the vehicle. As such, we believe that operators of commercial vehicle fleets should consider a number of factors when deciding whether to purchase our commercial electric vehicles (or commercial electric vehicles generally) or vehicles powered by internal combustion engines, particularly diesel-fueled or natural gas-fueled vehicles. We believe these factors include:

If, in weighing these factors, operators of commercial vehicle fleets determine that there is not a compelling business justification for purchasing commercial electric vehicles, particularly those that we produce and sell, then the market for commercial electric vehicles may not develop as we expect or may develop more slowly than we expect, which would adversely affect our business, prospects, financial condition and operating results.

If our customers are unable to efficiently and effectively integrate our electric vehicles into their existing commercial fleets our sales may suffer and our business, prospects, financial condition and operating results may be adversely affected.

Our sales strategy involves a comprehensive plan for the pilot and rollout of our electric vehicles, as well as the ongoing replacement of existing commercial vehicles with our electric vehicles, that is tailored to the individual needs of our customers. If we are unable to develop and execute fleet integration strategies or fleet management support services that meet our customers’ unique circumstances with minimal disruption to their businesses, our customers may not realize the economic benefits they expect from our electric vehicles. If this were to occur, our customers may not order additional vehicles from us, which could adversely affect our business, prospects, financial condition and operating results.

We currently do not have long-term supply contracts with guaranteed pricing which exposes us to fluctuations in component, materials and equipment prices. Substantial increases in these prices would increase our operating costs and could adversely affect our business, prospects, financial condition and operating results.

Because we currently do not have long-term supply contracts with guaranteed pricing, we are subject to fluctuations in the prices of the raw materials, parts and components and equipment we use in the production of our vehicles. Substantial increases in the prices for such raw materials, components and equipment would increase our operating costs and could reduce our margins if we cannot recoup the increased costs through increased vehicle prices. Any attempts to increase the announced or expected prices of our vehicles in response to increased costs could be viewed negatively by our customers and could adversely affect our business, prospects, financial condition and operating results.

If we are unable to scale our operations at our Union City facility in an expedited manner from our limited low volume production to high volume production, our business, prospects, financial condition and operating results will be adversely affected.

We are currently assembling our orders at our Union City facility, which has been acceptable for our historical orders. To satisfy increased demand, we will need to quickly scale operations in our Union City facility as well as scale our supply chain including access to batteries. Such a substantial and rapid increase in operations may strain our management capabilities. Our business, prospects, financial condition and operating results could be adversely affected if we experience disruptions in our supply chain, if we cannot obtain materials of sufficient quality at reasonable prices or if we are unable to scale our Union City facility.

We depend upon key personnel and need additional personnel. The loss of key personnel or the inability to attract additional personnel may adversely affect our business and results of operations.

Our success depends on the continuing services of our CEO, Duane Hughes and top management. On February 4, 2019, Mr. Hughes and the Company entered into an Executive Retention Agreement whereby Mr. Hughes was retained as Chief Executive Officer in consideration of an annual salary of $350,000. Further, on various dates, the Company entered Executive Retention Agreements with Rob Willison as Chief Operating Officer, Paul Gaitan as Chief Financial Officer and Julio Rodriguez as Chief Information Officer. The loss of any of these individuals could have a material and adverse effect on our business operations. Additionally, the success of our operations will largely depend upon our ability to successfully attract and maintain other competent and qualified key management personnel. As with any company with limited resources, there can be no guarantee that we will be able to attract such individuals or that the presence of such individuals will necessarily translate into profitability for our company. Our inability to attract and retain key personnel may materially and adversely affect our business operations. Any failure by our management to effectively anticipate, implement, and manage the changes required to sustain our growth would have a material adverse effect on our business, financial condition, and results of operations.

We face intense competition. Some of our competitors have substantially greater financial or other resources, longer operating histories and greater name recognition than we do and could use their greater resources and/or name recognition to gain market share at our expense or could make it very difficult for us to establish market share.

Companies currently competing in the fleet logistics market offering alternative fuel medium-duty trucks include Ford Motor Company and Freightliner. Ford and Freightliner are currently selling alternative fuel fleet vehicles including hybrids. Ford and Freightliner have substantially more financial resources, established market positions, long-standing relationships with customers and dealers, and who have more significant name recognition, technical, marketing, sales, financial and other resources than we do. Although we believe that HorseFly™, our unmanned aerial system (“UAS”), is unique in the marketplace in that it currently does not have any competitors when it comes to a UAS that works in combination with a truck, there are better-financed competitors in this emerging industry, including Google and Amazon. While we are seeking to partner with existing delivery companies to improve their efficiencies in the last mile of delivery, our competitors are seeking to redefine the delivery model using drones from a central location requiring extended flight patterns. Our competitors’ new aerial delivery model would essentially eliminate traditional package delivery companies. Our model is focused on coupling our delivery drone with delivery trucks supplementing the existing model and providing shorter-term flight patterns. Google and Amazon have more significant financial resources, established market positions, long-standing relationships with customers, more significant name recognition and a larger scope of resources including technical, marketing and sales than we do.

The market for personal VTOL aircraft is new, rapidly evolving, characterized by rapidly changing technologies, price competition, additional competitors, evolving government regulation and industry standards, frequent new vehicle announcements and changing consumer demands and behaviors. The market is highly competitive, and the SureFly™ design is competing with experimental aircraft from large original equipment manufacturers, or OEMs, small OEMs, other aviation related companies, technology companies and entrepreneurs. Currently, there are several VTOL aircraft being developed that have some similarity to SureFly™, including eHang and Volocopter.

The resources available to our competitors to develop new products and introduce them into the marketplace exceed the resources currently available to us. As a result, our competitors may be able to compete more aggressively and sustain that competition over a longer period than we can. This intense competitive environment may require us to make changes in our products, pricing, licensing, services, distribution, or marketing to develop a market position. Each of these competitors has the potential to capture significant market share in our target markets, which could have an adverse effect on our position in our industry and on our business and operating results.

If we are unable to keep up with advances in electric vehicle technology, we may suffer a decline in our competitive position.

There are companies in the electric vehicle industry that have developed or are developing vehicles and technologies that compete or will compete with our vehicles. We cannot assure that our competitors will not be able to duplicate our technology or provide products and services similar to ours more efficiently. If for any reason we are unable to keep pace with changes in electric vehicle technology, particularly battery technology, our competitive position may be adversely affected. We plan to upgrade or adapt our vehicles and introduce new models to continue to provide electric vehicles that incorporate the latest technology. However, there is no assurance that our research and development efforts will keep pace with those of our competitors.

Our electric vehicles compete for market share with vehicles powered by other vehicle technologies that may prove to be more attractive than ours are.

Our target market currently is serviced by manufacturers with existing customers and suppliers using proven and widely accepted fossil fuel technologies. Additionally, our competitors are working on developing technologies that may be introduced in our target market. If any of these alternative technology vehicles can provide lower fuel costs, greater efficiencies, greater reliability or otherwise benefit from other factors resulting in an overall lower total cost of ownership, this may negatively affect the commercial success of our vehicles or make our vehicles uncompetitive or obsolete.

We currently have a limited number of customers, with whom we do not have long-term agreements, and expect that a significant portion of our future sales will be from a limited number of customers. The loss of any of these customers could materially harm our business.

A significant portion of our projected future revenue is expected to be generated from a limited number of fleet customers. Additionally, much of our business model is focused on building relationships with a few large fleet customers. Currently, we have no contracts with customers that include long-term commitments or minimum volumes that ensure future sales of vehicles. As such, a customer may take actions that negatively affect us for reasons that we cannot anticipate or control, such as reasons related to the customer’s financial condition, changes in the customer’s business strategy or operations or as the result of the perceived performance or cost-effectiveness of our vehicles. The loss of or a reduction in sales or anticipated sales to our most significant customers would have a material adverse effect on our business, prospects, financial condition and operating results.

Changes in the market for electric vehicles could cause our products to become obsolete or lose popularity.

The modern electric vehicle industry is in its infancy and has experienced substantial change in the last few years. To date, demand for electric vehicles has been slower than forecasted by industry experts. As a result, growth in the electric vehicle industry depends on many factors outside our control, including, but not limited to:

We cannot assume that growth in the electric vehicle industry will continue. Our business will suffer if the electric vehicle industry does not grow or grows more slowly than it has in recent years or if we are unable to maintain the pace of industry demands.

President Trump’s administration may create regulatory uncertainty for the alternative energy sector and may materially harm our business, financial condition and operating results.

President Trump’s administration may create regulatory uncertainty in the alternative energy sector. During the election campaign, President Trump made comments suggesting that he was not supportive of various clean energy programs and initiatives designed to curtail global warming. Since taking office, President Trump has released his America First Energy Plan that relies on fossil fuels, cancelled U.S. participation in the Paris Climate Agreement and signed several executive orders relating to oil pipelines. It remains unclear what specifically President Trump would or would not do with respect to these programs and initiatives, and what support he would have for any potential changes to such legislative programs and initiatives in the Unites States Congress. If President Trump and/or the United States Congress take action or publicly speak out about the need to eliminate or further reduce legislation, regulations and incentives supporting alternative energy or take action to further support the use of fossil fuels, such actions may result in a decrease in demand for alternative energy in the United States and may materially harm our business, financial condition and operating results.

The unavailability, reduction, elimination or adverse application of government subsidies, incentives and regulations could have an adverse effect on our business, prospects, financial condition and operating results.

We believe that, currently, the availability of government subsidies and incentives including those available in California and other areas is an important factor considered by our customers when purchasing our vehicles, and that our growth depends in part on the availability and amounts of these subsidies and incentives. Any reduction, elimination or discriminatory application of government subsidies and incentives because of budgetary challenges, policy changes, the reduced need for such subsidies and incentives due to the perceived success of electric vehicles or other reasons may result in the diminished price competitiveness of the alternative fuel vehicle industry.

We may be unable to keep up with changes in electric vehicle technology and, as a result, may suffer a decline in our competitive position.

Our current products are designed for use with, and are dependent upon, existing electric vehicle technology. As technologies change, we plan to upgrade or adapt our products to continue to provide products with the latest technology. However, our products may become obsolete or our research and development efforts may not be sufficient to adapt to changes in or to create the necessary technology. Thus, our potential inability to adapt and develop the necessary technology may harm our competitive position.

The failure of certain key suppliers to provide us with components could have a severe and negative impact upon our business.

We have secured supply agreements for our critical components, including our batteries. However, the agreements are dependent on volume to ensure that they are available at a competitive price. Further, we rely on a small group of suppliers to provide us with components for our products. If these suppliers become unwilling or unable to provide components or if we are unable to meet certain volume requirements in our existing supply agreements, there are a limited number of alternative suppliers who could provide them and the price for them could be substantially higher. Changes in business conditions, wars, governmental changes, and other factors beyond our control or which we do not presently anticipate could negatively affect our ability to receive components from our suppliers. Further, it could be difficult to find replacement components if our current suppliers fail to provide the parts needed for these products. A failure by our major suppliers to provide these components could severely restrict our ability to manufacture our products and prevent us from fulfilling customer orders in a timely fashion.

Product liability or other claims could have a material adverse effect on our business.

The risk of product liability claims, product recalls, and associated adverse publicity is inherent in the manufacturing, marketing, and sale of electrical vehicles. Although we have product liability insurance for our consumer and commercial products, that insurance may be inadequate to cover all potential product claims. We also carry liability insurance on our products. Any product recall or lawsuit seeking significant monetary damages either in excess of our coverage, or outside of our coverage, may have a material adverse effect on our business and financial condition. We may not be able to secure additional product liability insurance coverage on acceptable terms or at reasonable costs when needed. A successful product liability claim against us could require us to pay a substantial monetary award. Moreover, a product recall could generate substantial negative publicity about our products and business and inhibit or prevent commercialization of other future product candidates. We cannot provide assurance that such claims and/or recalls will not be made in the future.

We may have to devote substantial resources to implementing a retail product distribution network.

Dealers are often hesitant to provide their own financing to contribute to our product distribution network. Thus, we anticipate that we may have to provide financing or other consignment sale arrangements for dealers. A capital investment such as this presents many risks, foremost among them being that we may not realize a significant return on our investment if the network is not profitable. Our inability to collect receivables from dealers could cause us to suffer losses. Additionally, the amount of time that our management will need to devote to this project may divert them from performing other functions necessary to assure the success of our business. We have established a non-exclusive distribution agreement with Ryder to lower this risk.

Regulatory requirements may have a negative impact upon our business.

While our vehicles are subject to substantial regulation under federal, state, and local laws, we believe that our vehicles are or will be materially in compliance with all applicable laws. However, to the extent the laws change, or if we introduce new vehicles in the future, some or all of our vehicles may not comply with applicable federal, state, or local laws. Further, certain federal, state, and local laws and industrial standards currently regulate electrical and electronics equipment. Although standards for electric vehicles are not yet generally available or accepted as industry standards, our products may become subject to federal, state, and local regulation in the future. Compliance with these regulations could be burdensome, time consuming, and expensive.

Our products are subject to environmental and safety compliance with various federal and state regulations, including regulations promulgated by the EPA, NHTSA, FAA and various state boards, and compliance certification is required for each new model year. The cost of these compliance activities and the delays and risks associated with obtaining approval can be substantial. The risks, delays, and expenses incurred in connection with such compliance could be substantial.

Our success may be dependent on protecting our intellectual property rights.

We rely on trade secret protections to protect our proprietary technology as well as several registered patents and five patent applications. Our patents relate to the vehicle chassis assembly, vehicle header and drive module and manifold for electric motor drive assembly. Our existing patent applications relates to the onboard generator drive system for electric vehicles, the delivery drone, and the manned multicopter. Our success will, in part, depend on our ability to obtain additional trademarks and patents. We are working on registering additional patents and trademarks with the United States Patent and Trademark Office but have not finalized any as of this date. Although we have entered into confidentiality agreements with our employees and consultants, we cannot be certain that others will not gain access to these trade secrets. Others may independently develop substantially equivalent proprietary information and technologies or otherwise gain access to our trade secrets. We do not maintain proprietary rights agreements with our employees, which agreements would further protect our intellectual property rights against claims by our employees. Therefore we may be subject to disputes with our employees over ownership of any new technologies or enhancements that such employees help to develop.

Our business may be adversely affected by union activities.

Although none of our employees are currently represented by a labor union, it is common throughout the automotive industry for many employees at automotive companies to belong to a union, which can result in higher employee costs and increased risk of work stoppages. Our employees may join or seek recognition to form a labor union, or we may be required to become a union signatory. Our production facility in Union City, Indiana was purchased from Navistar. Prior employees of Navistar were union members and our future work force at this facility may be inclined to vote in favor of forming a labor union. Furthermore, we are directly or indirectly dependent upon companies with unionized work forces, such as parts suppliers and trucking and freight companies, and work stoppages or strikes organized by such unions could have a material adverse impact on our business, financial condition or operating results. If a work stoppage occurs, it could delay the manufacture and sale of our trucks and have a material adverse effect on our business, prospects, operating results or financial condition. The mere fact that our labor force could be unionized may harm our reputation in the eyes of some investors and thereby negatively affect our stock price. Consequently, the unionization of our labor force could negatively impact our company’s health.

We may be exposed to liability for infringing upon the intellectual property rights of other companies.

Our success will, in part, depend on our ability to operate without infringing on the proprietary rights of others. Although we have conducted searches and are not aware of any patents and trademarks that our products or their use might infringe, we cannot be certain that infringement has not occurred or will not occur. We could incur substantial costs, in addition to the great amount of time lost, in defending any patent or trademark infringement suits or in asserting any patent or trademark rights, in a suit with another party.

Our electric vehicles make use of lithium-ion battery cells, which, if not appropriately managed and controlled, have occasionally been observed to catch fire or vent smoke and flames. If such events occur in our electric vehicles, we could face liability associated with our warranty, for damage or injury, adverse publicity and a potential safety recall, any of which would adversely affect our business, prospects, financial condition and operating results.

The battery packs in our electric vehicles use lithium-ion cells, which have been used for years in laptop computers and cell phones. On occasion, if not appropriately managed and controlled, lithium-ion cells can rapidly release the energy they contain by venting smoke and flames in a manner that can ignite nearby materials. Highly publicized incidents of laptop computers and cell phones bursting into flames have focused consumer attention on the safety of these cells. These events also have raised questions about the suitability of these lithium-ion cells for automotive applications. There can be no assurance that a field failure of our battery packs will not occur, which would damage the vehicle or lead to personal injury or death and may subject us to lawsuits. Furthermore, there is some risk of electrocution if individuals who attempt to repair battery packs on our vehicles do not follow applicable maintenance and repair protocols. Any such damage or injury would likely lead to adverse publicity and potentially a safety recall. Any such adverse publicity could adversely affect our business, prospects, financial condition and operating results. Warranty expense for the years ended December 31, 2018 and 2017 were $8.0 million and $0.1 million, respectively. The increase during the current year relates to issues with certain battery packs in our 2016 and 2017 E-GEN and E-100 vehicles. During the fourth quarter of 2018, the battery pack monitoring software indicated that some of the battery packs were not performing at expected levels. Some vehicles have undergone replacement of battery pack components. The Company is continuing to investigate the issue and explore potential quality issues with certain vendors. As a result of the above information, the Company increased its warranty reserve by $6.9 million in the fourth quarter of 2018.

We are subject to significant corporate and accounting regulation as a public company and failure to comply with all applicable regulations could subject us to liability or negatively affect our stock price.

As a publicly traded company, we are subject to a significant body of regulation, including the Sarbanes-Oxley Act of 2002. While we have developed and instituted a corporate compliance program based on what we believe are the current best practices in corporate governance and continue to update this program in response to newly implemented or changing regulatory requirements, we cannot provide assurance that we are or will be in compliance with all potentially applicable corporate regulations. In connection with management’s assessment of our internal control over financial reporting as required under Section 404 of the Sarbanes-Oxley Act of 2002, we identified material weaknesses pertaining to the lack of established adequate financial reporting activities and the lack of established proper accounting and financing reporting oversight. We cannot provide assurance that, in the future, our management will not find additional material weakness in connection with its annual review of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act. We also cannot provide assurance that we will be able to remediate existing weaknesses and any such additional weakness identified; our failure to do so would prevent our management from concluding that our internal control over financial reporting as of the end of our fiscal year is effective. If we fail to comply with any of these regulations, we could be subject to a range of regulatory actions, fines or other sanctions or litigation. If we must disclose any material weakness in our internal control over financial reporting, our stock price could decline.

Cyber attacks could adversely affect the company

The Company faces a heightened risk of cyber-attack. Cyber-attacks may include hacking, viruses, malware, denial of service attacks, ransomware or other data security breaches. The Company’s business requires the continued operation of information systems and network infrastructure. In the event of a cyber-attack that the Company was unable to defend against or mitigate, the Company could have its operations and the operations of its customers and others disrupted. The Company could also have their financial and other information systems and network infrastructure impaired, property damaged and customer and employee information stolen; experience substantial loss of revenues, response costs and other financial loss; and be subject to increased regulation, litigation, penalties and damage to their reputation. The Company has experienced cyber-attacks, although none of the attacks had a material impact.

Risks Related to Owning Our Common Stock

If we fail to continue to meet the listing standards of Nasdaq, our common stock may be delisted, which could have a material adverse effect on the liquidity of our common stock.

Our common stock is currently listed on the Nasdaq Capital Market. The Nasdaq Stock Market LLC has requirements that a company must meet in order to remain listed on Nasdaq. In particular, Nasdaq rules require us to maintain a minimum bid price of $1.00 per share of our common stock. The Company was notified on December 4, 2018 that pursuant to Nasdaq Listing Rule 5810(c)(3)(A), it would be afforded 180 calendar days, or until June 3, 2019, to regain compliance with the minimum bid price requirement. We are not currently in compliance with the minimum bid price requirement, and there can be no assurance that we will meet the regain compliance with the minimum bid price requirement, or any other requirement in the future. If we fail to regain compliance with the minimum bid price requirement, The Nasdaq Stock Market LLC may initiate the delisting process with a notification letter. If we were to receive such a notification, we would be afforded a grace period of 180 calendar days to regain compliance with the minimum bid price requirement. In order to regain compliance, shares of our common stock would need to maintain a minimum closing bid price of at least $1.00 per share for a minimum of 10 consecutive trading days.

In addition, Nasdaq rules require us to meet at least one of the following criteria: (i) stockholder’s equity of at least $2.5 million; (ii) market value of listed securities of at least $35 million for 30 consecutive business days; or (iii) annual net income from continuing operations of at least $1 million. As of December 31, 2018, we did not comply with the stockholder’s equity and net income criteria, and we do not expect that we will comply with either criterion in the foreseeable future. During the 30-day period ending April 29, 2019, the market value of our common stock ranged between $31.9 million and $58.4 million. Accordingly, a substantial decline in our share price, which closed at $0.8246 on April 29, 2019, to below $0.60 could cause us to fall out of compliance with the market capitalization listing criterion. If this were to occur and we were not able to cure this failure with applicable grace periods, the Nasdaq Market may initiate the process of delisting our common stock.

If we are delisted from Nasdaq, trading in our shares of common stock may be conducted, if available, on the “OTC Bulletin Board Service” or, if available, via another market. In the event of such delisting, an investor would likely find it significantly more difficult to dispose of, or to obtain accurate quotations as to the value of the shares of our common stock, and our ability to raise future capital through the sale of the shares of our common stock or other securities convertible into or exercisable for our common stock could be severely limited. A determination could also then be made that our common stock is a “penny stock” which would require brokers trading in our common stock to adhere to more stringent rules and possibly result in a reduced level of trading. This could have a long-term impact on our ability to raise future capital through the sale of our common stock.

Existing anti-dilution provisions will result in the issuance of additional shares and warrants to purchase shares in connection with this offering and future equity issuances.

In connection with this offering, the Company will issue 116,496 shares of common stock to the February 2019 Accredited Investors and warrants to purchase a total of 439,714 shares of common stock at an exercise price of $0.8140 per share to Marathon and its affiliates due to existing anti-dilution provisions in the Marathon Agreement. In the future, we may offer additional securities which could also trigger these anti-dilution provisions. We may also offer additional securities with similar anti-dilution provisions in the future.  The issuance of the additional shares of common stock and warrants to purchase shares of common stock as a result of existing or future anti-dilution provisions may result in substantial additional dilution to existing stockholders and could have a material adverse effect on the market price of our common stock.

The trading of our shares of common has been relatively thin and there is no assurance that a liquid market for our shares of common stock will develop.

Our common stock has traded on the Nasdaq Capital Market, under the symbol “WKHS”, since January 2016. Since that date, our common stock has been traded relatively thinly. There can be no assurance that we will be able to successfully develop a liquid market for our common shares. The stock market in general, and early stage public companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of such companies. If we are unable to develop a market for our common shares, you may not be able to sell your common shares at prices you consider to be fair or at times that are convenient for you, or at all.

Our stock price and trading volume may be volatile, which could result in substantial losses for our stockholders.

The equity trading markets may experience periods of volatility, which could result in highly variable and unpredictable pricing of equity securities. The market price of our common stock could change in ways that may or may not be related to our business, our industry or our operating performance and financial condition. In addition, the trading volume in our common stock has been low and may fluctuate and cause significant price variations to occur. We have experienced significant volatility in the price of our stock. In addition, the stock markets in general can experience considerable price and volume fluctuations.

We have not paid cash dividends in the past and have no immediate plans to pay cash dividends.

We plan to reinvest all of our earnings, to the extent we have earnings, in order to develop our products, deliver on our orders and cover operating costs and to otherwise become and remain competitive. We do not plan to pay any cash dividends with respect to our securities in the foreseeable future. We cannot assure you that we would, at any time, generate sufficient surplus cash that would be available for distribution to the holders of our common stock as a dividend. Therefore, you should not expect to receive cash dividends on our common stock.

Shares eligible for future sale may adversely affect the market for our common stock.

Of the 61,496,990 shares of our common stock outstanding as of April 29, 2019, approximately 52.1 million shares are held by “non-affiliates” and may be freely tradable without restriction assuming compliance with Rule 144. In addition, we have previously filed Registration Statements on Form S-3 for purposes of registering the resale of 3,033,717 shares of common stock and 8,085,519 shares of common stock issuable upon exercise of stock purchase warrants that have been declared effective, and pursuant to this registration statement we are registering an additional 9,306,661 shares of common stock issuable upon exercise of the Warrants. Any substantial resale of our common stock pursuant to Rule 144 or pursuant to any resale prospectus may have a material adverse effect on the market price of our common stock.

We have only approximately 14.6 million shares of capital stock remaining for issuance.

As of April 29, 2019, we have 61,496,990 shares of Common Stock issued and outstanding. In addition, we have 5,723,552 shares of Common Stock reserved for issuance under stock options and 18,177,294 shares of Common Stock reserved for issuance under warrants. Our articles of incorporation only authorize our company to issue 100 million shares of Common Stock. In the event we need to issue additional shares of our Common Stock in one or more financing transactions to fund our operations, in connection with grants of equity compensation to reward our employees, directors and consultants, or upon the exercise of our currently outstanding options and warrants, we will not be able to issue more than 14.6 million shares of our common stock without obtaining approval of our stockholders to increase our authorized shares of Common Stock. Although we intend to seek our stockholders’ approval to amend our articles of incorporation to increase our authorized shares of Common Stock to 250,000,000 at a special meeting of the stockholders we expect will be held on May 2, 2019, there can be no assurance that such approval will be granted. Accordingly, we may not have enough authorized shares of stock remaining for the purposes described above. Failure of our shareholders to approve the increase to our authorized shares would significantly limit our ability to issue equity securities and raise additional capital, which could require us to curtail operations.

Shareholders may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the price per share in our prior offerings. We may sell shares or other securities in any future offering at a price per share that is lower than the price per share paid by historical investors, which would result in those newly issued shares being dilutive. In addition, investors purchasing shares or other securities in this offering or the future offerings could have rights superior to existing stockholders, which could impair the value of existing shareholders. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions may be higher or lower than the price per share paid by our historical investors.

Our charter documents and Nevada law may inhibit a takeover that stockholders consider favorable.

Provisions of our certificate of incorporation and bylaws and applicable provisions of Nevada law may delay or discourage transactions involving an actual or potential change in control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. The provisions in our certificate of incorporation and bylaws:

There are limitations on director/officer liability.

As permitted by Nevada law, our certificate of incorporation limits the liability of our directors for monetary damages for breach of a director’s fiduciary duty except for liability in certain instances. As a result of our charter provision and Nevada law, shareholders may have limited rights to recover against directors for breach of fiduciary duty. In addition, our certificate of incorporation provides that we shall indemnify our directors and officers to the fullest extent permitted by law.

FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying base prospectus and the documents we have filed with the SEC that are incorporated by reference herein and therein contain forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In addition, from time to time we or our representatives have made or will make forward-looking statements in various other filings that we make with the SEC or in other documents, including press releases or other similar announcements. Forward-looking statements concern our current plans, intentions, beliefs, expectations and statements of future economic performance. Statements containing terms such as “will,” “may,” “believe,” “do not believe,” “plan,” “expect,” “intend,” “estimate,” “anticipate” and other phrases of similar meaning are considered to be forward-looking statements.

Forward-looking statements are based on our assumptions and are subject to known and unknown risks and uncertainties that could cause actual results to differ materially from those reflected in or implied by these forward-looking statements. Factors that might cause actual results to differ include, among others, those set forth under “Risk Factors” in this prospectus supplement and those discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operation” in our most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q and in our future periodic reports filed with the SEC, all of which are incorporated by reference herein. The following are important factors, among others, that could cause actual results, performance or achievements to differ materially from the results, performance or achievements reflected in our forward-looking statements:

Readers are cautioned not to place undue reliance on any forward-looking statements contained in this prospectus supplement, the accompanying base prospectus or the documents we have filed with the SEC that are incorporated by reference herein and therein, which reflect management’s views and opinions only as of their respective dates. We assume no obligation to update forward-looking statements to reflect actual results, changes in assumptions or changes in other factors affecting such forward-looking statements, except to the extent required by applicable securities laws. You are advised, however, to consult any additional disclosures we have made or will make in the filings we make with the SEC, including reports on Forms 10-K, 10-Q and 8-K. All subsequent forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements contained in this prospectus supplement, the accompanying base prospectus or any related issuer free writing prospectus.

USE OF PROCEEDS

We estimate that our net proceeds from this offering will be approximately $2.9 million, after deducting the estimated offering expenses payable by us.

We expect to use the net proceeds from this offering for working capital and general corporate purposes.

DILUTION

If you invest in our common stock, you will experience immediate dilution to the extent of the difference between the price per share you pay in this offering and the proforma net tangible book value per share of our common stock after this offering. For the purpose of this calculation, the entire purchase price for the shares of common stock is being allocated to the shares of common stock.

Our net tangible book value as of December 31, 2018 was approximately $(15.4) million, or approximately $(0.26) per share.

After giving effect to the sale of 3,957,432 shares of our common stock in this offering at an per share offering price of $0.74 per share and the intended use of proceeds thereof and after deducting the estimated offering expenses payable by us, our pro forma adjusted net tangible book value as of December 31, 2018 would have been approximately $(12.5) million, or approximately $(0.20) per share. This represents an immediate increase in net tangible book value of approximately $0.06 per share to our existing stockholders and immediate dilution in net tangible book value of approximately $0.68 per share to investors participating in this offering. The following table illustrates this calculation on a per share basis:

The number of shares of our common stock expected to be outstanding after this offering is based on 61,496,990 shares of common stock outstanding as of April 29, 2019, and excludes the following:

The above illustration of dilution per share to investors participating in this offering assumes no exercise of outstanding options or warrants to purchase our common stock. The exercise of outstanding options or warrants having an exercise price less than the offering price would increase dilution to investors participating in this offering. In addition, we may choose to raise additional capital depending on market conditions, our capital requirements and strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through our sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

PLAN OF DISTRIBUTION

We are offering the shares of common stock directly to certain institutional investor. The offering is not being made through an underwriter or placement agent. We have entered into a subscription agreement with this investor for the full amount of the offering. The form of subscription agreement is included as an exhibit to our Current Report on Form 8-K that we will file with the SEC in connection with the consummation of this offering. See “Where You Can Find More Information.”

Our obligation to issue and sell shares to the purchasers is subject to the conditions set forth in the subscription agreement. The purchaser’s obligation to purchase shares is subject to conditions set forth in the subscription agreement as well.

The purchasers have agreed not to (i) offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any of the purchased shares or (ii) enter into any swap or other transaction or arrangement that transfers or that is designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, any of the economic consequences of ownership of the purchased shares for a period of six months after the date of this prospectus supplement, without our prior written consent.

The public offering price of the securities we are offering was negotiated between us and the investor based on the trading of our common stock prior to the offering, among other things. Other factors considered in determining the public offering price of the shares include the history and prospects of the Company, the stage of development of our business, our business plans for the future and the extent to which they have been implemented, an assessment of our management, general conditions of the securities markets at the time of the offering and such other factors as were deemed relevant.

RISK FACTORS

An investment in our securities involves a high degree of risk. You should carefully consider the risk factors and all other information contained in our most recent Annual Report on Form 10-K, in our Quarterly Reports on Form 1 0-Q and Current Reports on Form 8-K before investing in our securities. You should also consider similar information contained in any Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other document filed by us with the SEC after the date of this prospectus before deciding to invest in our securities. If any of these risks were to occur, our business, financial condition or results of operations could be adversely affected. In that case, the trading price of our common stock or other securities could decline and you could lose all or part of your investment. When we offer and sell any securities pursuant to a prospectus supplement, we may include additional risk factors relevant to such securities in the prospectus supplement.

FORWARD LOOKING STATEMENTS

OUR COMPANY

We are a last mile delivery technology company headquartered in the United States. We have broad capabilities beginning with the development and production of American made battery-electric medium-duty truck chassis helping delivery fleets achieve efficiencies and strengthening their sustainability initiatives. To the best of our knowledge, we are the only medium-duty battery-electric original equipment manufacturer (OEM) in the United States. We have also recently commenced the development of an electric pickup work truck with range extender for fleet usage. With a focus on last mile delivery and expanding on fleets’ operational efficiencies, Workhorse also develops and integrates unmanned aerial vehicle (UAV) platforms. Our drone delivery platform, HorseFly™ is FAA compliant and fully integrated with our medium duty truck chassis. Workhorse also develops and integrates cloud-based, real-time proof-of-performance telematics monitoring software that provides fleet operators with advanced vehicle diagnostics, energy and route efficiency.

On June 4, 2014, we entered into a Vehicle Purchase Agreement with United Parcel Service Inc. (“UPS”), pursuant to which we outlined with UPS the relationship by which we would sell vehicles to UPS. On August 7, 2015, we entered into a Prime Order under the Vehicle Purchase Agreement with UPS, pursuant to which UPS agreed to purchase 125 E-GEN trucks. In connection with each purchase order, we develop a delivery schedule as well as locations for specific deliveries. However, these deadlines are expected to evolve as UPS operations personnel from eight states will be involved in the scheduling. On September 7, 2016, we entered into a purchase order with UPS pursuant to which UPS agreed to purchase from the Company 200 E-GEN electric extended range delivery trucks.

Workhorse had previously entered into a purchase agreement with UPS to supply 18 all-electric Workhorse E-100 Walk-In Vans to be deployed in the Houston-Galveston, Texas area. The U.S. Department of Energy selected this project to improve local air quality in the Houston-Galveston area, which is currently designated as a National Ambient Air Quality Non-Attainment Area. We fulfilled this order in July 2016.

We have developed and begun delivery of our second generation, full-electric truck, “E-100”, which is a significant improvement over our first generation E-100 vehicle. The second-generation vehicle includes a single powerful electric motor with no transmission and lighter, high-density Lithium-ion batteries, giving the vehicle a range of up to 100 miles. We have filed a patent application for the system that extends the range of electric vehicles while reducing the overall cost of the typical battery-electric power train. The system, E-GENTM, is designed specifically for the package delivery vehicle market, in which the diesel and/or gasoline-powered vehicles in use now are required to stop and restart hundreds of times a day. Our E-GEN system incorporates a small internal combustion engine that powers an integrated electric motor as a generator when the battery pack reaches a pre-determined depth-of-discharge (DOD). The DOD is calculated based on projected route distance, package loads and electricity efficiency curves. The gas engine never propels the vehicle. Its task is simple: to automatically turn on in the event the battery needs a small re-charge. We believe that the range-extended battery-electric technology is an ideal fit for urban and suburban delivery routes, despite the typical fleet owner’s concerns about range and cost. Our E-GEN Drive system will enable our customers to keep their batteries charged to a consistent state of charge throughout the day and, since we are able to use smaller battery packs, we can reduce the cost of the entire system. Our E-GEN trucks offer a three-year payback, making them price competitive with gasoline-powered trucks. We recently entered into an agreement with Bayerische Motoren Werke AG (BMW) to supply the new quiet-running 2-cylinder gasoline generator replacing the current 4-cylinder engine to extend the range of our E-GEN product.

In March of 2013, we purchased the former Workhorse Custom Chassis assembly plant in Union City, Indiana from Navistar International. With this acquisition, we acquired the capability to be an Original Equipment Manufacturer (OEM) of Class 3-6 commercial-grade, medium-duty truck chassis, to be marketed under the Workhorse® brand. Ownership and operation of this plant enables us to build new chassis with gross vehicle weight capacities of between 10,000 and 26,000 pounds. These chassis are our new 88-track (W88) and include either of our two second-generation, battery-electric drive trains, both powered by Panasonic 18650 Li-ion cells. The W88 truck chassis is currently being offered to fleet purchasing managers at price points that are both attractive and cost competitive. At the same time, we intend to partner with engine suppliers and body fabricators to offer fleet-specific, custom, purpose-built chassis that provide total cost of ownership solutions that are superior to the competition.

In addition to having the ability to build our own chassis, we design and produce battery-electric power trains that can be installed in new Workhorse chassis or installed as repower packages to convert used Class 3-6 medium-duty vehicles from diesel or gasoline power to electric power. Our approach is to provide battery-electric power trains utilizing proven, automotive-grade, mass-produced parts in their architectures, coupled with in-house control software that we have developed over the last five years.

The Workhorse Custom Chassis acquisition provides other important assets including the Workhorse brand and logo, intellectual property, schematics, logistical support from Up-Time Parts (a Navistar subsidiary) and a network of 400-plus sales and service outlets across North America. We believe the combination of our chassis assembly capability, coupled with its ability to offer an array of fuel choices, gives Workhorse a unique opportunity in the marketplace.

We are also seeking to re-design the future of parcel delivery aviation: HorseFly™, an Unmanned Aerial Vehicle (UAV) that is designed for the package delivery market as well as other commercial applications. Our UAV works in tandem with our electric trucks to bring a practical low cost solution to making the last mile more efficient and cost effective for our parcel customers. HorseFly™ is designed to further improve package delivery efficiencies and has been developed in conjunction with the University of Cincinnati. In June 2016, the Federal Aviation Administration (or the FAA) announced new rules permitting commercial use of drones weighing less than 55 pounds subject to certain restrictions including maintaining visual contact.

We recently developed Metron® which is a system that provides fleet operators advanced energy and route efficiency while enabling them to monitor, control and update software remotely. We are also currently in the initial stages of developing a self-driving software to further differentiate us as the technology company with the most cost effective last mile delivery system in the marketplace.

On March 6, 2015, we responded to a Request for Information and Prequalification (RFI) from the United States Postal Service (USPS) for its Next Generation Delivery Vehicle (NGDV) Acquisition Program. The USPS operates a fleet of over 200,000 vehicles in all areas of the United States and its territories. Approximately 163,000 of these vehicles are right hand drive, light-duty carrier route vehicles purchased between 1987 and 2001. They are not current with advancements in vehicle technologies such as drivetrains, emissions, and safety related features. The postal service intends to retire this fleet in coming years, and to replace them with Next Generation Delivery Vehicles (NGDVs). NGDVs must be capable of delivering both mail to curbside mailboxes and parcel packages in a safe and efficient manner. The postal service states that NGDVs are also expected to benefit from today’s availability of practical technological improvements for drivetrains, bodies, chassis, safety systems, security, and innovative designs to improve vehicle loading and delivery operations. The USPS anticipates making a single award in 2017 to a supplier for up to 180,000 NGDVs to replace its current fleet of mail delivery vehicles. Delivery of the NGDVs to the USPS is expected to begin in 2018. On April 14, 2015, the USPS notified Workhorse that it had advanced in the NGDV Acquisition Program as a prequalified supplier. Workhorse partnered with VT Hackney, Inc. (“VT Hackney”), another pre-qualified supplier, to design and build the body, and the joint response to the USPS NGDV RFP was delivered by the USPS deadline of February 5, 2016. On March 18, 2016, Workhorse and VT Hackney attended by invitation from the USPS a meeting to present our RFP response and respond to questions. On September 16, 2016, the USPS awarded the contract for the NGDV Prototype to six prime suppliers including VT Hackney. Workhorse and VT Hackney have entered into a Teaming Agreement pursuant to which Workhorse was appointed as the exclusive subcontractor to provide the chassis and powertrain for the prototypes.

USE OF PROCEEDS

Unless we indicate otherwise in an accompanying prospectus supplement, we intend to use the net proceeds from the sale of our securities offered by this prospectus for general corporate purposes, which may include, but not be limited to, working capital, capital expenditures, acquisitions, refinancing of indebtedness and repurchases or redemptions of securities.

We will not receive any proceeds from the sales of shares of common stock by the selling stockholders. However, in the event a selling shareholder exercises a Stock Purchase Warrant for cash, we will use the proceeds for general corporate purposes, which may include, but not be limited to, working capital, capital expenditures, acquisitions, refinancing of indebtedness and repurchases or redemptions of securities.

SELLING SHAREHOLDERS

We have agreed to register 1,033,717 shares of common stock presently outstanding and 1,833,193 shares of common stock issuable upon exercise of Stock Purchase Warrants that are beneficially owned by the selling shareholders identified below.

In November and December 2016, we entered into Warrant Exercise Agreements with the selling shareholders identified below pursuant to which, each of the warrant holders agreed to exercise at least one-third of their Stock Purchase Warrants (the “Warrant Exercises”). In consideration of the warrant holders exercising the minimum required amount, we agreed to register for resale all shares of common stock issued in connection with the Warrant Exercise and the remaining shares of common stock that may be issued upon exercise of the Stock Purchase Warrants in the future. As a result of the Warrant Exercises, we received gross proceeds of $3,889,329 and issued 915,217 shares of common stock to the warrant holders (the “November Shares”). In addition, in September 2016, a selling shareholder exercised 143,500 shares of common stock (the “September Shares” and collectively with the November Shares, the “Exercised Shares”) under a Stock Purchase Warrant for $5.28 per share for aggregate consideration of $757,680. We are required to register the Exercised Shares, less 25,000 Exercised Shares held by Gerald Budde, a director of our company, as well as 1,833,193 shares of common stock underlying the Stock Purchase Warrants. Maxim Group LLC (“Maxim”) acted as solicitation agent for the Warrant Exercises. The Company paid Maxim a cash fee equal to 6.0% of the Warrant Exercise proceeds, as well as fees and expenses of $10,000. In addition, we paid Maxim $140,000 as exclusive consideration of Maxim terminating its advisory agreement and the related right of first refusal for any future financing therein.

The description contained herein of the terms of the Warrant Exercise Agreement does not purport to be complete and is qualified in its entirety by reference to the form of Warrant Exercise Agreement, a copy of which was attached as Exhibit 10.1 to this Registration Statement.

Other than as described herein, the selling shareholders do not have, and within the past three years have not had, any position, office or material relationship with us or any of our predecessors or affiliates.

The following table sets forth the names of the selling shareholders, the numbers of shares of our common stock beneficially owned by such shareholders as of December 12, 2016, and the numbers of shares that may be offered for resale by the selling shareholders from time to time as described in the “Plan of Distribution.” The shares of common stock may also be sold by donees, pledgees, and other transferees or successors in interest of the selling stockholders.

The selling shareholders may decide to sell all, some, or none of the shares of common stock. We currently have no agreements, arrangements or understandings with any of the selling shareholders regarding the sale of the shares of common stock covered by this prospectus. We cannot provide you with any estimate of the number of shares of our common stock that the selling shareholders will hold in the future.

For purposes of this table, beneficial ownership is determined in accordance with the Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and includes voting power and investment power with respect to such shares. In calculating the percentage ownership or percent of equity vote for a given individual or group, the number of shares of common stock outstanding for that individual or group includes unissued shares subject to options, warrants, rights or conversion privileges exercisable within sixty days held by such individual or group, but are not deemed outstanding by any other person or group.

The applicable percentage of ownership is based on an aggregate of 27,576,717 shares of our common stock issued and outstanding on December 12, 2016.

DESCRIPTION OF CAPITAL STOCK

Our articles of incorporation provide that we are authorized to issue 50 million shares of common stock, par value $0.001 per share, and 75 million shares of preferred stock, par value $0.001 per share.

Common Stock

Voting Rights

The holders of our common stock are entitled to one vote per share on all matters to be voted upon by our shareholders, including the election of directors. Cumulative voting is not permitted in the election of directors.

Dividend Rights

Subject to preferences that may apply to shares of preferred stock outstanding at the time, the holders of outstanding shares of our common stock are entitled to receive dividends out of funds legally available if our board of directors, in its discretion, determines to issue dividends and then only at the times and in the amounts that our board may determine.

Liquidation Rights

In the event of our liquidation, dissolution, or winding up, our common shareholders will receive ratably any net assets that remain after the payment of all of our debts and other liabilities, subject to the senior rights of any outstanding preferred stock.

Other

Our shares of common stock are not convertible into any other security and do not have any preemptive rights, conversion rights, redemption rights or sinking fund provisions. The rights, preferences and privileges, including voting rights, of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of preferred stock that the board may designate and issue in the future. There are currently no preferred shares outstanding.

Preferred Stock

We are authorized to issue up to 75 million shares of preferred stock, in one or more series with such designations, relative rights, preferences, voting rights, limitations, dividend rates, redemption prices, liquidation prices, conversion rights, sinking or purchase fund rights, and other provisions as the board may fix or determine.

Anti-Takeover Provisions Under Nevada Law.

Combinations with Interested Stockholder. Sections 78.411-78.444, inclusive, of the Nevada Revised Statutes (“NRS”) contain provisions governing combinations with an interested stockholder. For purposes of the NRS, “combinations” include: (i) any merger or consolidation with any interested stockholder, (ii) any sale, lease, exchange, mortgage, pledge, transfer or other disposition to any interested stockholder of corporate assets with an aggregate market value equal to 5% or more of the aggregate market value of the corporation’s consolidated assets, 5% or more of the outstanding shares of the corporation or 10% or more of the earning power or net income of the corporation, (iii) the issuance to any interested stockholder of voting shares (except pursuant to a share dividend or similar proportionate distribution) with an aggregate market value equal to 5% or more of the aggregate market value of all the outstanding shares of the corporation, (iv) the dissolution of the corporation if proposed by or on behalf of any interested stockholder, (v) any reclassification of securities, recapitalization or corporate reorganization that will have the effect of increasing the proportionate share of the corporation’s outstanding voting shares held by any interested stockholder and (vi) any receipt by the interested stockholder of the benefit (except proportionately as a stockholder) of any loan, advance, guarantee, pledge or other financial assistance. For purposes of the NRS, an “interested stockholder” is defined to include any beneficial owner of more than 10% of any class of the voting securities of a Nevada corporation and any person who is an affiliate or associate of the corporation and was at any time during the preceding three years the beneficial owner or more than 10% of any class of the voting securities of the Nevada corporation.

Subject to certain exceptions, the provisions of the NRS governing combinations with interested stockholders provide that a Nevada corporation may not engage in a combination with an interested stockholder for two years after the date that the person first became an interested stockholder unless the combination or the transaction by which the person first became an interested stockholder is approved by the board of directors before the person first became an interested stockholder.

Control Share Acquisitions. The NRS also contains a “control share acquisitions statute.” If applicable to a Nevada corporation this statute restricts the voting rights of certain stockholders referred to as “acquiring persons,” that acquire or offer to acquire ownership of a “controlling interest” in the outstanding voting stock of an “issuing corporation.” For purposes of these provisions a “controlling interest” means with certain exceptions the ownership of outstanding voting stock sufficient to enable the acquiring person to exercise one-fifth or more but less than one-third, one-third or more but less than a majority, or a majority or more of all voting power in the election of directors and “issuing corporation” means a Nevada corporation that has 200 or more stockholders of record, at least 100 of whom have addresses in Nevada appearing on the stock ledger of the corporation, and which does business in Nevada directly or through an affiliated corporation. The voting rights of an acquiring person in the affected shares will be restored only if such restoration is approved by the holders of a majority of the voting power of the corporation. The NRS allows a corporation to “opt-out” of the control share acquisitions statute by providing in such corporation’s articles of incorporation or bylaws that the control share acquisitions statute does not apply to the corporation or to an acquisition of a controlling interest specifically by types of existing or future stockholders, whether or not identified.

Articles of Incorporation and Bylaws

No Cumulative Voting. Where cumulative voting is permitted in the election of directors, each share is entitled to as many votes as there are directors to be elected and each shareholder may cast all of its votes for a single director nominee or distribute them among two or more director nominees. Thus, cumulative voting makes it easier for a minority shareholder to elect a director. Our articles of incorporation deny shareholders the right to vote cumulatively.

Authorized But Unissued Shares. Our articles of incorporation permit the board to authorize the issuance of preferred stock, and to designate the rights and preferences of our preferred stock, without obtaining shareholder approval. One of the effects of undesignated preferred stock may be to enable the board to render more difficult or to discourage a third party’s attempt to obtain control of Workhorse Group by means of a tender offer, proxy contest, merger, or otherwise. The issuance of shares of preferred stock also may discourage a party from making a bid for the common stock because the issuance may adversely affect the rights of the holders of common stock. For example, preferred stock that we issue may rank prior to the common stock as to dividend rights, liquidation preference, or both, may have special voting rights and may be convertible into shares of common stock. Accordingly, the issuance of shares of preferred stock may discourage bids for our common stock or may otherwise adversely affect the market price of our common stock.

Transfer Agent or Registrar

Empire Stock Transfer, Inc. is the transfer agent and registrar of our common stock.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of common stock or preferred stock. Warrants may be issued independently or together with common stock or preferred stock offered by any prospectus supplement and may be attached to or separate from any such offered securities. Series of warrants may be issued under a separate warrant agreement entered into between us and a bank or trust company, as warrant agent, all as will be set forth in the prospectus supplement relating to the particular issue of warrants. The warrant agent would act solely as our agent in connection with the warrants and would not assume any obligation or relationship of agency or trust for or with any holders of warrants or beneficial owners of warrants.

The following summary of certain provisions of the warrants does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all provisions of the warrant agreements.

Reference is made to the prospectus supplement relating to the particular issue of warrants offered pursuant to such prospectus supplement for the terms of and information relating to such warrants, including, where applicable:

Warrants will be issued in registered form only. The exercise price for warrants will be subject to adjustment in accordance with the applicable prospectus supplement.

Each warrant will entitle the holder thereof to purchase such number of shares of common stock or preferred stock at such exercise price as shall in each case be set forth in, or calculable from, the prospectus supplement relating to the warrants, which exercise price may be subject to adjustment upon the occurrence of certain events as set forth in such prospectus supplement. After the close of business on the expiration date, or such later date to which such expiration date may be extended by us, unexercised warrants will become void. The place or places where, and the manner in which, warrants may be exercised shall be specified in the prospectus supplement relating to such warrants.

Prior to the exercise of any warrants to purchase common stock or preferred stock, holders of such warrants will not have any of the rights of holders of common stock or preferred stock, as the case may be, purchasable upon such exercise, including the right to receive payments of dividends, if any, on the common stock purchasable upon such exercise, or to exercise any applicable right to vote.

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities together with other securities or separately, as described in the applicable prospectus supplement, under an indenture to be entered into between our company and the trustee that meets certain requirements identified in the applicable prospectus supplement.

We may issue the debt securities in one or more series with the same or various maturities, at par, at a premium, or at a discount. We will describe the particular terms of each series of debt securities in a prospectus supplement relating to that series, which we will file with the SEC.

The prospectus supplement will set forth, to the extent required, the following terms of the debt securities in respect of which the prospectus supplement is delivered:

One or more debt securities may be sold at a substantial discount below their stated principal amount. We may also issue debt securities in bearer form, with or without coupons. If we issue discount debt securities or debt securities in bearer form, we will describe material U.S. federal income tax considerations and other material special considerations which apply to these debt securities in the applicable prospectus supplement.

We may issue debt securities denominated in or payable in a foreign currency or currencies or a foreign currency unit or units. If we do, we will describe the restrictions, elections, and general tax considerations relating to the debt securities and the foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the prospectus supplement. Global securities will be issued in registered form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security will be described in the applicable prospectus supplement.

DESCRIPTION OF UNITS

The following description, together with the additional information we include in any applicable prospectus supplement, summarizes the general features of the units that we may offer under this prospectus. We may issue units consisting of two or more other constituent securities. These units may be issuable as, and for a specified period of time may be transferable only as a single security, rather than as the separate constituent securities comprising such units. While the features we have summarized below will generally apply to any units we may offer under this prospectus, we will describe the particular terms of any units that we may offer in more detail in the applicable prospectus supplement. The specific terms of any units may differ from the description provided below as a result of negotiations with third parties in connection with the issuance of those units, as well as for other reasons. Because the terms of any units we offer under a prospectus supplement may differ from the terms we describe below, you should rely solely on information in the applicable prospectus supplement if that summary is different from the summary in this prospectus.

We urge you to read the applicable prospectus supplement related to the specific units being offered, as well as the complete instruments that contain the terms of the securities that comprise those units. Certain of those instruments, or forms of those instruments, have been or will be filed as exhibits to the registration statement of which this prospectus is a part, and supplements to those instruments or forms may be incorporated by reference into the registration statement of which this prospectus is a part from reports we file with the Commission.

If we offer any units, certain terms of that series of units will be described in the applicable prospectus supplement, including, without limitation, the following, as applicable:

PLAN OF DISTRIBUTION

We and the selling shareholders may sell securities in and outside the United States through underwriters or dealers, directly to purchasers or through agents or in ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers. To the extent required by applicable law, a prospectus supplement will include the following information:

Sale Through Underwriters or Dealers

If we use underwriters in the sale of securities, the underwriters will acquire the securities for their own account. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to conditions, and the underwriters will be obligated to purchase all the securities if they purchase any securities. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include over allotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, whereby selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if such offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, these activities may be discontinued at any time.

If we or the selling shareholders use dealers in the sale of securities, we or the selling shareholders will sell the securities to them as principals. They may then resell the securities to the public at varying prices determined by the dealers at the time of resale. The dealers participating in any sale of the securities may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of such securities. We will include in any prospectus supplement the names of the dealers and the terms of the transactions.

We will bear costs relating to all of the securities being registered under this registration statement of which this prospectus forms a part.

Any broker-dealers or other persons acting on our behalf or on behalf of the selling shareholder that participate with us in the distribution of the securities may be deemed to be underwriters and any commissions received or profit realized by them on the resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. As of the date of this prospectus, we are not a party to any agreement, arrangement or understanding between any broker or dealer and us with respect to the offer or sale of the securities pursuant to this prospectus.

Pursuant to a requirement by the Financial Industry Regulatory Authority, or FINRA, the maximum commission or discount to be received by any FINRA member or independent broker/dealer may not be greater than eight percent (8%) of the gross proceeds received by us for the sale of any securities being registered pursuant to SEC Rule 415 under the Securities Act. If more than 5% of the net proceeds of any offering of securities made under this prospectus will be received by a FINRA member participating in the offering or its affiliates or associated persons of such FINRA member, the offering will be conducted in accordance with FINRA Conduct Rule 5121.

Direct Sales and Sales Through Agents

We and the selling shareholders may sell the securities directly. In that event, no underwriters or agents would be involved. We and the selling shareholders may also sell the securities through agents we designate from time to time. In the prospectus supplement, we will name any agent involved in the offer or sale of the securities, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of the securities. We will describe the terms of any such sales in the prospectus supplement.

Delayed Delivery Contracts

If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement.

Subscription Offerings

We may also make direct sales through subscription rights distributed to our existing stockholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights to our stockholders, if all of the underlying securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or may engage the services of one or more underwriters, dealers or agents, including standby underwriters, to sell the unsubscribed securities to third parties.

General Information

We may have agreements with the agents, dealers and underwriters to indemnify them against civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the agents, dealers or underwriters may be required to make. Agents, dealers and underwriters may engage in transactions with us or perform services for us in the ordinary course of their businesses.

Certain legal matters with respect to the shares of our securities offered by this prospectus will be passed upon for us by Fleming PLLC, Rockville Centre, New York. Any underwriters, dealers or agents will be advised about other issues relating to any transaction by their own legal counsel.
