SUMMARY

This summary highlights selected information appearing elsewhere in this prospectus. Because it is a summary, it may not contain all of the information that may be important to you. To understand this offering fully, you should read this entire prospectus carefully, including the information set forth under the heading “Risk Factors” and our financial statements.

The Company

We design, develop and sell electrified powertrain solutions that can be installed on Class 8 trucks from most major commercial vehicle OEMs. Our mission is to be the leading provider of electrified powertrain solutions for the commercial vehicle industry. Our goal is to reduce the carbon intensity and the greenhouse gas (“GHG”) emissions of the transportation sector by providing electrified powertrain solutions for Class 8 commercial vehicles at the lowest total cost of ownership (“TCO”). Our solutions utilize our proprietary battery systems, control software and data analytics, combined with fully integrated electric motors and power electronics, to produce electrified powertrain systems that either augment, in the case of our hybrid electric powertrain (“Hybrid”) systems, or fully replace, in the case of the fully electric Hypertruck Electric Range Extender (“Hypertruck ERX”) system, traditional diesel or natural gas fueled powertrains and improve their performance. By reducing both GHG emissions and TCO, our environmentally conscious solutions support our customers’ pursuit of their sustainability and financial objectives.

Background

We were originally known as Tortoise Acquisition Corp. On October 1, 2020, TortoiseCorp consummated the Business Combination with Legacy Hyliion pursuant to the Business Combination Agreement dated as of June 18, 2020 among TortoiseCorp, Legacy Hyliion and Merger Sub. In connection with the Closing of the Business Combination, TortoiseCorp changed its name to Hyliion Holdings Corp. Legacy Hyliion was deemed to be the accounting acquirer in the Merger based on an analysis of the criteria outlined in Accounting Standards Codification 805. While TortoiseCorp was the legal acquirer in the Merger, because Legacy Hyliion was deemed the accounting acquirer, the historical financial statements of Legacy Hyliion became the historical financial statements of the combined company, upon the consummation of the Merger.

Immediately prior to the effective time of the Merger (the “Effective Time”), each share of Legacy Hyliion preferred stock (“Legacy Hyliion Preferred Stock”) that was issued and outstanding was automatically converted into a share of Legacy Hyliion common stock, par value $0.001 per share (“Legacy Hyliion Common Stock”), such that each converted share of Legacy Hyliion Preferred Stock was no longer outstanding and ceased to exist, and each holder of Legacy Hyliion Preferred Stock thereafter ceased to have any rights with respect to such securities.

Also immediately prior to the Effective Time, the outstanding principal and unpaid accrued interest due on Legacy Hyliion’s outstanding convertible notes (“Legacy Hyliion Convertible Notes”) immediately prior to the Effective Time were automatically converted into shares of Legacy Hyliion Common Stock in accordance with the terms of such Legacy Hyliion Convertible Notes, and such converted Legacy Hyliion Convertible Notes were no longer outstanding and ceased to exist, and any liens securing obligations under the Legacy Hyliion Convertible Notes were released.

At the Effective Time, each share of Legacy Hyliion Common Stock was converted into and exchanged for 1.45720232 shares (the “Exchange Ratio”) of our Common Stock.

At the Effective Time, all shares of Legacy Hyliion Common Stock and Legacy Hyliion Preferred Stock held in the treasury of Legacy Hyliion were canceled without any conversion thereof and no payment or distribution was made with respect thereto.

At the Effective Time, each share of common stock, par value $0.0001 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time was converted into and exchanged for one validly issued, fully paid and nonassessable share of Legacy Hyliion Common Stock.

Each Legacy Hyliion option that was outstanding immediately prior to the Effective Time, whether vested or unvested, was converted into an option to purchase a number of shares of Common Stock (such option, an “Exchanged Option”) equal to the product (rounded up or down to the nearest whole number, with a fraction of

Table of Contents

0.5 rounded up) of (i) the number of shares of Legacy Hyliion Common Stock subject to such Legacy Hyliion option immediately prior to the Effective Time and (ii) the Exchange Ratio, at an exercise price per share (rounded up or down to the nearest whole cent, with a fraction of $0.005 rounded up) equal to (A) the exercise price per share of such Legacy Hyliion option immediately prior to the Effective Time, divided by (B) the Exchange Ratio. Except as specifically provided in the Business Combination Agreement, following the Effective Time, each Exchanged Option will continue to be governed by the same terms and conditions (including vesting and exercisability terms) as were applicable to the corresponding former Legacy Hyliion option immediately prior to the Effective Time.

No certificates or scrip or shares representing fractional shares of Common Stock were issued upon the exchange of Legacy Hyliion Common Stock. Any fractional shares were rounded up or down to the nearest whole share of Common Stock, with a fraction of 0.5 rounded up. No cash settlements were made with respect to fractional shares eliminated by such rounding.

Pursuant to our prior amended and restated certificate of incorporation, each share of TortoiseCorp’s Class B Common Stock, par value $0.0001 per share (the “Class B Common Stock”), converted into one share of TortoiseCorp’s Class A Common Stock, par value $0.0001 per share (the “Class A Common Stock”), at the Closing. After the Closing and following the effectiveness of our second amended and restated certificate of incorporation (“Certificate of Incorporation”), each share of Class A Common Stock was automatically reclassified, redesignated and changed into one validly issued, fully paid and non-assessable share of Common Stock, without any further action by us or any stockholder.

On October 1, 2020, a number of purchasers (each, a “Subscriber”) purchased from the Company an aggregate of 30,750,000 shares of Common Stock (the “PIPE Shares”), for a purchase price of $10.00 per share and an aggregate purchase price of $307,500,000, pursuant to separate subscription agreements (each, a “Subscription Agreement”) entered into effective as of June 18, 2020. Pursuant to the Subscription Agreements, the Company gave certain registration rights to the Subscribers with respect to the PIPE Shares. The sale of PIPE Shares was consummated concurrently with the Closing.

On October 1, 2020, Atlas Point Energy Infrastructure Fund, LLC (“Atlas Point Fund”) purchased 1,750,000 TortoiseCorp units (consisting of one share of Common Stock and one half of one Warrant, the “Forward Purchase Units”), consisting of 1,750,000 shares of Common Stock (the “Forward Purchase Shares”) and Forward Purchase Warrants to purchase 875,000 shares of Common Stock, for an aggregate purchase price of $17,500,000, and transferred 894,375 shares of Common Stock to TortoiseEcofin Borrower LLC (formerly known as “Tortoise Borrower LLC” and hereinafter referred to as “Tortoise Borrower”) pursuant to the Amended and Restated Forward Purchase Agreement, dated February 6, 2019 (“Amended and Restated Forward Purchase Agreement”), as amended by the First Amendment to Amended and Restated Forward Purchase Agreement, dated June 18, 2020 (“First Amendment to the Forward Purchase Agreement”) (as amended, “Forward Purchase Agreement”).

Our Common Stock and Public Warrants are currently listed on the NYSE under the symbols “HYLN” and “HYLN WS,” respectively.

The rights of holders of our Common Stock and Warrants are governed by our Certificate of Incorporation, our amended and restated bylaws (the “Bylaws”) and the Delaware General Corporation Law (the “DGCL”), and, in the case of the Warrants, the Warrant Agreement, dated February 27, 2019 (the “Warrant Agreement”), between TortoiseCorp and the Continental Stock Transfer & Trust Company, as the warrant agent (the “Warrant Agent”). See the sections entitled “Description of our Securities” and “Certain Relationships and Related Party Transactions.”

RISK FACTORS

Investing in our securities involves risks. Before you make a decision to buy our securities, in addition to the risks and uncertainties discussed above under “Cautionary Note Regarding Forward-Looking Statements,” you should carefully consider the specific risks set forth herein. If any of these risks actually occur, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our securities could decline, and you could lose all or part of your investment. Additionally, the risks and uncertainties described in this prospectus or any prospectus supplement are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

Risks Related to our Business and Industry

We are an early stage company with a history of losses, and expect to incur significant expenses and continuing losses for the foreseeable future.

We incurred a net loss of $9.6 million for the six months ended June 30, 2020 and have incurred a net loss of approximately $43.0 million from January 1, 2018 through June 30, 2020. We believe that we will continue to incur operating and net losses each quarter until at least the time we begin commercial deliveries of both of our Hybrid systems and our Hypertruck ERX system, which are not expected to begin until 2021 and 2022, respectively, and may occur later or not at all. Even if we are able to successfully develop and sell our electrified powertrain solutions, there can be no assurance that they will be commercially successful. Our potential profitability is dependent upon the successful development and successful commercial introduction and acceptance of our electrified powertrain solutions, which may not occur.

We expect the rate at which we will incur losses to be significantly higher in future periods as we:

• continue to market our first generation (“V1”) Hybrid system and design, develop and produce our second generation (“V2”) Hybrid system as well as our Hypertruck ERX system;

• hire additional employees across all divisions of the company;

• continue to utilize our third-party partners for design, testing and commercialization;

• expand our production capabilities to produce our electrified powertrain solutions, including costs associated with outsourcing the production of our electrified powertrain solutions;

• build up inventories of parts and components for our electrified powertrain solutions;

• produce an inventory of our electrified powertrain solutions;

• expand our design, development, installation and servicing capabilities;

• increase our sales and marketing activities and develop our distribution infrastructure; and

• increase our general and administrative functions to support our growing operations.

Because we will incur the costs and expenses from these efforts before we receive any incremental revenues with respect thereto, our losses in future periods will be significant. In addition, we may find that these efforts are more expensive than we currently anticipate or that these efforts may not result in revenues, which would further increase our losses.

Our financial results may vary significantly from period to period due to fluctuations in our operating costs and other factors.

Our quarterly and annual operating results may fluctuate significantly, which makes it difficult for us to predict our future operating results. These fluctuations may occur due to a variety of factors, many of which are outside of our control, including:

• pace at which we continue to design, develop and produce new products and increase production capacity;

Table of Contents

• the number of customer orders in a given period;

• changes in manufacturing costs;

• the timing and cost of, and level of investment in, research and development relating to our technologies and our current or future facilities;

• developments involving our competitors;

• changes in governmental regulations or applicable law;

• future accounting pronouncements or changes in our accounting policies; and

• general market conditions and other factors, including factors unrelated to our operating performance or the operating performance of our competitors.

As a result of these factors, we believe that quarter-to-quarter comparisons of our financial results, especially in the short term, are not necessarily meaningful and that these comparisons cannot be relied upon as indicators of future performance. Moreover, our financial results may not meet expectations of equity research analysts, ratings agencies or investors, who may be focused only on quarterly financial results. If any of this occurs, the trading price of our Common Stock and Warrants could fall substantially, either suddenly or over time.

We may be unable to adequately control the costs associated with our operations.

We will require significant capital to develop and grow our business, including developing and producing our electrified powertrain solutions and building our brand. We expect to incur significant expenses which will impact our profitability, including research and development expenses (including developing our V2 Hybrid system as well as our Hypertruck ERX system), raw material procurement costs, sales and distribution expenses as we build our brand and market our electrified powertrain solutions, and general and administrative expenses as we scale our operations and incur costs as a public company. In addition, we may incur significant costs servicing our electrified powertrain solutions. Our ability to become profitable in the future will not only depend on our ability to complete the design and development of our electrified powertrain solutions to meet projected performance metrics and successfully market our electrified powertrain solutions and services, but also to sell our products at prices to achieve our expected margins and control our costs. If we are unable to efficiently design, produce, market, sell, distribute and service our electrified powertrain solutions, our margins, profitability and prospects would be materially and adversely affected.

Our business model has yet to be tested and any failure to commercialize our strategic plans would have a material adverse effect on our operating results and business, harm our reputation and could result in substantial liabilities that exceed our resources.

Investors should be aware of the difficulties normally encountered by a new enterprise, many of which are beyond our control, including substantial risks and expenses in the course of establishing or entering new markets, organizing operations and undertaking marketing activities. The likelihood of our success must be considered in light of these risks, expenses, complications, delays and the competitive environment in which we operate. Therefore, there can be no assurances that our business plan will prove successful. We may not be able to generate significant revenue, raise additional capital or operate profitably. We will continue to encounter risks and difficulties frequently experienced by early stage companies, including scaling up our infrastructure and headcount, and may encounter unforeseen expenses, difficulties or delays in connection with our growth. In addition, as a result of the capital-intensive nature of our business, we can be expected to continue to sustain substantial operating expenses without generating sufficient revenues to cover expenditures. Any investment in us are therefore highly speculative and could result in the loss of your entire investment.

Our limited operating history makes evaluating our business and future prospects difficult and may increase the risk of your investment.

You must consider the risks and difficulties we face as an early stage company with a limited operating history. If we do not successfully address these risks, our business, prospects, financial condition and operating results will be materially and adversely harmed. Legacy Hyliion was incorporated in January 2016 and has a very

Table of Contents

limited operating history on which investors can base an evaluation of our business, prospects, financial condition and operating results. We intend to derive the majority of our revenues from the sale of our electrified powertrain solutions, of which commercial deliveries of the Hybrid systems and the Hypertruck ERX system are not expected to begin until 2021 and 2022 respectively, and may occur later or not at all. There are no assurances that we will be able to secure future business with customers, such as the major commercial vehicle OEMs, trucking companies and other fleet owners.

It is difficult to predict our future revenues and appropriately budget for our expenses, and we have limited insight into trends that may emerge and affect our business. In the event that actual results differ from our estimates or we adjust our estimates in future periods, our operating results and financial position could be materially affected. The projected financial information appearing elsewhere in this prospectus has been prepared by our management and reflects current estimates of future performance. The projected results depend on the successful implementation of our management’s growth strategies and are based on assumptions and events over which we have only partial or no control. The assumptions underlying such projected information require the exercise of judgement and may not occur, and the projections are subject to uncertainty due to the effects of economic, business, competitive, regulatory, legislative, political and other changes.

We have identified material weaknesses in our internal control over financial reporting which, if not corrected, could affect the reliability of our consolidated financial statements and have other adverse consequences.

We have identified material weaknesses in internal control over financial reporting, which relate to: (a) the design and operation of our information technology general controls; (b) our overall closing and financial reporting processes, including accounting for significant and unusual transactions; and (c) general segregation of duties, including the review and approval of journal entries.

In the course of preparing the financial statements that are included in this prospectus, we have identified a number of adjustments to our financial statements that resulted in a restatement of previously issued financial statements. These adjustments relate to accounting for a business acquisition, accounting for issuance of convertible notes payable and embedded derivative liabilities, accounting for costs associated with materials and supplies purchased for research and development activities and other miscellaneous adjustments.

A material weakness is a deficiency or combination of deficiencies in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our financial statements would not be prevented or detected on a timely basis. These deficiencies could result in additional misstatements to our financial statements that would be material and would not be prevented or detected on a timely basis.

Our management has concluded that these material weaknesses in our internal control over financial reporting are due to the fact that, prior to the Closing, Legacy Hyliion was a private company with limited resources and did not have the necessary business processes and related internal controls formally designed and implemented; coupled with the appropriate resources, level of experience and technical expertise to oversee its business processes and controls surrounding: information technology general controls, and our closing and financial reporting processes to address the accounting and financial reporting requirements related to significant and unusual transactions.

Our management is in the process of developing a remediation plan. The material weaknesses will not be considered remediated until management designs and implements effective controls that operate for a sufficient period of time and management has concluded, through testing, that these controls are effective. Our management will monitor the effectiveness of our remediation plans and will make changes management determines to be appropriate.

If not remediated, these material weaknesses could result in further material misstatements to our annual or interim financial statements that would not be prevented or detected on a timely basis, or in delayed filing of required periodic reports. If we are unable to assert that our internal control over financial reporting is effective, or when required in the future, if our independent registered public accounting firm is unable to express an unqualified opinion as to the effectiveness of the internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our Common Stock could be adversely affected and we could become subject to litigation or investigations by the NYSE, the SEC or other regulatory authorities, which could require additional financial and management resources.

We plan to accept reservation orders for the sale of our electrified powertrain solutions that are cancellable, and our initial pre-launch sales order for Hypertruck ERX equipped trucks is cancellable.

Our electrified powertrain solutions are still in the development and testing phase and commercial deliveries of the Hybrid systems and the Hypertruck ERX system are not expected to begin until 2021 and 2022, respectively, and may occur later or not at all. As a result, we plan to accept reservation orders for our electrified powertrain solutions that will be cancellable by customers without penalty. Given the anticipated lead times between reservation orders and the delivery date of our electrified powertrain solutions, there is a heightened risk that customers who place reservation orders may ultimately decide not to convert such reservation orders into binding contracts and take delivery of their ordered electrified powertrain solutions from us due to potential changes in customer preferences, competitive developments and other factors. As a result, no assurance can be made that reservations will not be cancelled or that reservations will result in the purchase of our electrified powertrain solutions, and any such cancellations could harm our business, prospects, financial condition and operating results.

We may also enter into contracts for the sale of our electrified powertrain solutions that include various cancellation rights in favor of the customer. For example, in May 2020, we entered into a pre-launch sales agreement (the “Agility Pre-Launch Agreement”) with Agility Logistics Cargo Transport Co. WLL (“Agility Transport”), a company organized under the laws of and based in Kuwait and a subsidiary of Agility Public Warehousing Company K.S.C.P. Under the Agility Pre-Launch Agreement, Agility Transport agreed to order 1,000 trucks equipped with our Hypertruck ERX system in one or more future purchase orders, subject to certain testing and performance requirements and termination rights. If we are unable to deliver our Hypertruck ERX trucks according to the performance requirements and delivery timelines set forth in the contract, Agility Transport has the right to cancel our order. Additionally, even if we satisfy such performance requirements and delivery timelines, Agility Transport may terminate the Agility Pre-Launch Agreement by giving us 360-days’ advance notice after the date on which we have delivered a Hypertruck ERX demonstration truck. Furthermore, the Agility Pre-Launch Agreement does not specify the terms or periods upon which these purchase orders may be entered into, such that the sale of any Hypertruck ERX equipped trucks to Agility Transport is subject to the parties reaching an agreement on the terms of one or more purchase orders, including as to the amount of the deposit to be paid by Agility Transport to us in connection with such purchase order. Failure to reach agreement on the terms of such purchase order could result in Agility Transport refusing to purchase all or a portion of the 1,000 Hypertruck ERX equipped trucks that it pre-ordered. Should a dispute arise under the Agility Pre-Launch Agreement, we may face challenges enforcing the terms of such contract due to the jurisdictional challenges involved with instituting legal proceedings against a foreign entity and enforcing an award against such entity in a foreign jurisdiction. As a result, no assurance can be given that Agility Transport will not terminate the Agility Pre-Launch Agreement prior to purchasing all or any portion of the 1,000 Hypertruck ERX equipped trucks it pre-ordered under such agreement or that we would be able to enforce such agreement against Agility Transport. Any of these adverse actions related to the Agility Pre-Launch Agreement or any future customer contracts could harm our business, prospects, financial condition and operating results.

We may not be able to successfully engage target customers or convert early trial deployments with truck fleets into meaningful orders or additional deployments in the future.

Our success, and our ability to increase revenue and operate profitably, depends in part on our ability to identify target customers and to convert early trial deployments with truck fleets into meaningful orders or additional deployments in the future. Our V1 Hybrid system has been delivered to certain customers on an early trial deployment basis, where such customers have the ability to evaluate whether the V1 Hybrid system meets such customers’ performance and other requirements before such customers commit to meaningful orders or additional deployments in the future. If we are unable to meet our customers’ performance requirements or industry specifications, identify target customers or convert early trial deployments in truck fleets into meaningful orders or obtain additional deployments in the future, our business, prospects, financial condition and operating results would be materially adversely affected.

Certain of our strategic, development and deployment arrangements could be terminated or may not materialize into long-term contract partnership arrangements.

We have arrangements with strategic, development and deployment partners and collaborators. Some of these arrangements are evidenced by non-binding letters of intent, early stage agreements that are used for design

Table of Contents

and development purposes but will require renegotiation at later stages of development or production or master agreements that have yet to be implemented under separately negotiated statements of work, each of which could be terminated or may not materialize into next-stage contracts or long-term contract partnership arrangements. For instance, we have entered into non-binding letters of intent with FEV North America Inc., IAV Automotive Engineering Inc., Lonestar Specialty Vehicles and Fontaine Modification Company. If these arrangements are terminated or if we are unable to enter into next-stage contracts or long-term operational contracts, our business, prospects, financial condition and operating results may be materially adversely affected.

We may need to raise additional funds and these funds may not be available to us when we need them. If we cannot raise additional funds when we need them, our business, prospects, financial condition and operating results could be negatively affected.

The design, production, sale and servicing of our electrified powertrain solutions is capital-intensive. In connection with the consummation of the Business Combination on October 1, 2020, we raised net proceeds of approximately $519.9 million (net of transaction costs and expenses). However, we may subsequently determine that additional funds are necessary earlier than anticipated. This capital may be necessary to fund our ongoing operations, continue research, development and design efforts, create new products and improve infrastructure. We may raise additional funds through the issuance of equity, equity related or debt securities or through obtaining credit from government or financial institutions. We cannot be certain that additional funds will be available to us on favorable terms when required, or at all. If we cannot raise additional funds when we need them, our business, prospects, financial condition and operating results could be materially adversely affected.

If we fail to manage our growth effectively, including failing to attract and integrate qualified personnel, we may not be able to develop, produce, market and sell our electrified powertrain solutions successfully.

Any failure to manage our growth effectively could materially and adversely affect our business, prospects, operating results and financial condition. We intend to expand our operations significantly. We expect our future expansion to include:

• expanding the management team;

• hiring and training new personnel;

• leveraging consultants to assist with company growth and development;

• forecasting production and revenue;

• controlling expenses and investments in anticipation of expanded operations;

• establishing or expanding design, production, sales and service facilities;

• implementing and enhancing administrative infrastructure, systems and processes; and

• expanding into international markets, including Europe.

We intend to continue to hire a significant number of additional personnel, including software engineers, design and production personnel and service technicians for our electrified powertrain solutions. Because our electrified powertrain solutions are based on a different technology platform than traditional internal combustion engines, individuals with sufficient training in alternative fuel and electric vehicles may not be available to hire, and as a result, we will need to expend significant time and expense training any newly hired employees. Competition for individuals with experience designing, producing and servicing electrified vehicles and their software is intense, and we may not be able to attract, integrate, train, motivate or retain additional highly qualified personnel, particularly with respect to software engineers in the Austin, Texas area. The failure to attract, integrate, train, motivate and retain these additional employees could seriously harm our business, prospects, financial condition and operating results.

The performance characteristics of our electrified powertrain solutions, including fuel economy and emissions levels, may vary, including due to factors outside of our control.

The performance characteristics of our electrified powertrain solutions, including fuel economy and emissions levels, may vary, including due to factors outside of our control. Our electrified powertrain solutions are still being designed and developed, and there are no assurances that they will be able to meet their projected performance characteristics, including fuel economy and emissions levels. External factors may also impact the performance characteristics of our electrified powertrain solutions. For instance, the estimated fuel savings and fuel economy of vehicles installed with our electrified powertrain solutions may vary depending on factors including, but not limited to, driver behavior, speed, terrain, hardware efficiency, payload, vehicle and weather conditions. Additionally, GHG emissions of vehicles installed with our electrified powertrain solutions may vary due to external factors, including the type of fuel, driver behavior, the efficiency and certification of the engine, where the engine is being operated and the characteristics of the vehicle itself, including but not limited to the vehicle’s software controls, drivetrain efficiency, aerodynamics and rolling resistance. These external factors as well as any operation of our electrified powertrain solutions other than as intended, may result in emissions levels that are greater than we expect. Additionally, the amount of GHG emissions of both the Hybrid and Hypertruck ERX solutions will vary due to, but not limited to, the factors mentioned above. The ability of our electrified powertrain solutions to have a net carbon negative profile, will depend on the availability of renewable natural gas (“RNG”) as well as the infrastructure necessary to purchase RNG through fuel providers. Any limitation on the ability to purchase RNG, such as a decrease or a limitation on the number of natural gas fueling stations or limitation on the production of natural gas and RNG in particular, will negatively impact the anticipated carbon intensity profile of our electrified powertrain solutions. In addition, the carbon intensity profiles could vary based on the source of RNG, which could reduce a fleet’s ability to have favorable carbon intensity scores. Due to these factors, there can be no guarantee that the operators of vehicles using our electrified powertrain solutions will realize the expected fuel savings and fuel economy and GHG emission reductions.

Our success will depend on our ability to economically outsource the production, assembly and installation of our electrified powertrain solutions at scale, and our ability to develop and produce electrified powertrain solutions of sufficient quality and appeal to customers on schedule and at scale is unproven.

Our business depends in large part on our ability to execute our plans to develop, produce, assemble, market, sell, install and service our electrified powertrain solutions. We currently design, assemble and test our electrified powertrain solutions at our facility in Cedar Park, Texas and in the future, plan to outsource the majority of the production, assembly and installation of our electrified powertrain solutions. We anticipate that a significant concentration of this production, assembly and installation will be performed by a small number of outsourcing partners. While these arrangements can lower operating costs, they also reduce our direct control over production and distribution. Such diminished control may have an adverse effect on the quality or quantity of products or services, or our flexibility to respond to changing conditions.

We rely on single-source suppliers to supply and produce many components, and anticipate relying on outsourcing partners for assembly and installation of our electrified powertrain solutions. Any failure of these suppliers or outsourcing partners to perform could require us to seek alternative suppliers or to expand our production capabilities, which could incur additional costs and have a negative impact on our cost or supply of components or finished goods. In addition, production or logistics in supply or production areas or transit to final destinations can be disrupted for a variety of reasons including, but not limited to, natural and man-made disasters, information technology system failures, commercial disputes, military actions, economic, business, labor, environmental, public health or political issues or international trade disputes.

Our continued development of our electrified powertrain solutions is and will be subject to risks, including with respect to:

• the equipment we plan to use being able to accurately produce our electrified powertrain solutions within specified design tolerances;

• the compatibility of our electrified powertrain solutions with existing and future commercial vehicle designs;

Table of Contents

• long- and short-term durability of the components in our electrified powertrain solutions in the day-to-day wear and tear of the commercial trucking environment;

• compliance with environmental, workplace safety and similar regulations;

• securing necessary components on acceptable terms and in a timely manner;

• delays in delivery of final component designs to our suppliers;

• our ability to attract, recruit, hire and train skilled employees;

• quality controls, particularly as we plan to expand our production capabilities;

• delays or disruptions in our supply chain;

• other delays and cost overruns; and

• our ability to secure additional funding if necessary.

We and our future production partners have no experience to date in high volume production of our electrified powertrain solutions. We do not know whether we or our future production partners will be able to develop efficient, automated, low-cost production capabilities and processes and reliable sources of component supply, that will enable us to meet the quality, price, engineering, design and production standards, as well as the production volumes, required to successfully mass market our electrified powertrain solutions. Even if we and our future production partners are successful in developing our high volume production capability and processes and reliably source our component supply, we do not know whether we will be able to do so in a manner that avoids significant delays and cost overruns, including as a result of factors beyond our control such as problems with suppliers and vendors, or in time to meet our vehicle commercialization schedules or to satisfy the requirements of customers. Any failure to develop such production processes and capabilities within our projected costs and timelines could have a material adverse effect on our business, prospects, financial condition and operating results.

We may experience significant delays in the design, production and launch of our electrified powertrain solutions, which could harm our business, prospects, financial condition and operating results.

Our electrified powertrain solutions are still in the development and testing phase, and commercial deliveries of the Hybrid systems and the Hypertruck ERX system are not expected to begin until 2021 and 2022, respectively, and may occur later or not at all. Any delay in the financing, design, production and launch of our electrified powertrain solutions, including future production of our V2 Hybrid system and Hypertruck ERX system at our outsourcing partners, could materially damage our brand, business, prospects, financial condition and operating results. There are often delays in the design, production and commercial release of new products, and to the extent we delay the launch of our electrified powertrain solutions, our growth prospects could be adversely affected as we may fail to grow our market share. We will rely on our outsourcing partners to produce our electrified powertrain solutions at scale, and if they are not able produce products that meet our specifications, we may need to expand our production capabilities, which would cause us to incur additional costs. Furthermore, we rely on third-party suppliers for the provision and development of many of the key components and materials used in our electrified powertrain solutions, and to the extent they experience any delays, we may need to seek alternative suppliers. If we experience delays by our third-party outsourcing partners or suppliers, we could experience delays in delivering on our timelines.

We, our outsourcing partners and our suppliers may rely on complex machinery for our production, which involves a significant degree of risk and uncertainty in terms of operational performance and costs.

We, our outsourcing partners and our suppliers may rely on complex machinery, for the production, assembly and installation of our electrified powertrain solutions, which will involve a significant degree of uncertainty and risk in terms of operational performance and costs. Our production facilities and the facilities of our outsourcing partners and suppliers consist of large-scale machinery combining many components. These components may suffer unexpected malfunctions from time to time and will depend on repairs and spare parts to resume operations, which may not be available when needed. Unexpected malfunctions of these components may significantly affect the intended operational efficiency. Operational performance and costs can be difficult to predict and are often

Table of Contents

influenced by factors outside of our control, such as, but not limited to, scarcity of natural resources, environmental hazards and remediation, costs associated with decommissioning of machines, labor disputes and strikes, difficulty or delays in obtaining governmental permits, damages or defects in electronic systems, industrial accidents, fire, seismic activity and natural disasters. Should operational risks materialize, it may result in the personal injury to or death of workers, the loss of production equipment, damage to production facilities, monetary losses, delays and unanticipated fluctuations in production, environmental damage, administrative fines, increased insurance costs and potential legal liabilities, all which could have a material adverse effect on our business, prospects, financial condition or operating results.

If we are unable to successfully produce our electrified powertrain solutions, our business will be harmed.

We currently produce our V1 Hybrid system at our facility in Cedar Park, Texas and expect to begin production of our V2 Hybrid system in 2021, at the earliest, and our Hypertruck ERX system in 2022, at the earliest, in each case at our outsourcing partners’ facilities. Our production facilities, the production facilities of our outsourcing partners and suppliers and the equipment used to produce our electrified powertrain solutions would be costly to replace and could require substantial lead time to replace and qualify for use. Our production facilities and the production facilities of our outsourcing partners and suppliers may be harmed or rendered inoperable by natural or man-made disasters, including earthquakes, flooding, fire and power outages, or by health epidemics, such as the recent COVID-19 pandemic, which may render it difficult or impossible for us to produce our electrified powertrain solutions for some period of time. The inability to produce our electrified powertrain solutions or the backlog that could develop if our production facilities and the production facilities of our outsourcing partners and suppliers are inoperable for even a short period of time may result in the loss of customers or harm our reputation. Although we maintain insurance for damage to our property and the disruption of our business, this insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, if at all.

We are dependent on large commercial vehicle OEMs and producers of glider kits and rolling chassis to provide vehicles for our electrified powertrain solutions.

Because we do not manufacture complete commercial vehicles, we are dependent on commercial vehicle OEMs and producers of glider kits and rolling chassis to provide vehicle chassis for our electrified powertrain solutions. If OEMs are unable or unwilling to integrate the installation of our electrified powertrain solutions into their commercial vehicle production lines, we may have to rely on producers of glider kits and rolling chassis and commercial truck upfitting and modification companies. To the extent that there are limitations on the availability of glider kits or rolling chassis, either due to the unwillingness or inability of OEMs and producers to produce and provide them to us or our installation partners, or a change in governmental regulations or policies, we would need to develop our own commercial vehicle on which to install our electrified powertrain solutions. Either case could have a negative impact on our ability to sell our electrified powertrain solutions at the prices, or achieve the margins, or in the timeframes that we anticipate. Additionally, if commercial vehicle OEMs limit or fail to provide a warranty on vehicles with our electrified powertrain solutions, we will incur additional costs by contracting with a third party to provide warranty services. Any of the foregoing would have a material adverse effect on our business, prospects, financial condition and operating results.

We will rely on third parties, including commercial truck upfitting and modification companies and commercial vehicle OEMs, to install our electrified powertrain solutions in vehicles, which is subject to risks.

We intend to enter into agreements with commercial truck upfitting and modification companies and commercial vehicle OEMs to install our electrified powertrain solutions. Using third-party contract manufacturers and installers for the production and installation of our electrified powertrain solutions is subject to risks with respect to operations that are outside our control. We could experience delays if our outsourcing partners do not meet agreed upon timelines or experience capacity constraints that make it impossible for us to fulfill purchase orders on time or at all. The installation of our solutions may also void the warranty of a vehicle or a vehicle’s components, such as our engine and transmission, which may reduce customer demand for our solutions. Additionally, we may permit returns of vehicles installed with our electrified powertrain solutions, which may result in significant additional costs to us if we are required to convert the vehicles back to their original form. There is risk of potential disputes with our outsourcing partners, and we could be affected by negative publicity related to our partners whether or not such publicity is related to their collaboration with us. Our ability to successfully build a premium brand could also be adversely affected by perceptions about the quality of our outsourcing partners’ products. In

Table of Contents

addition, although we are involved in each step of the supply chain, production and installation processes, because we also rely on our outsourcing partners and third parties to meet our quality standards, there can be no assurance that the final product will meet expected quality standards.

We may be unable to enter into new agreements or extend existing agreements with third-party contract manufacturers and installers on terms and conditions acceptable to us and therefore may need to contract with other third parties or significantly add to our own production capacity. There can be no assurance that in such event we would be able to engage other third parties or establish or expand our own production capacity to meet our needs on acceptable terms or at all. The expense and time required to complete any transition, and to assure that our electrified powertrain solutions produced at facilities of new producers comply with our quality standards and regulatory requirements, may be greater than anticipated. Any of the foregoing could adversely affect our business, prospects, financial condition and operating results.

We intend to sell our electrified powertrain solutions to large commercial vehicle OEM customers and large volume customers, and the failure to obtain such customers, loss of sales to such customers or failure to negotiate acceptable terms in contract renewal negotiations could have an adverse impact on our business.

Although we intend to sell our electrified powertrain solutions to commercial vehicle OEMs and other large volume customers, we may not be able to establish relationships with such OEMs or large volume customers if customer demand is not as high as we expect or if commercial vehicle OEMs face pressure from their existing suppliers not to purchase our electrified powertrain solutions. We may enter into long-term contracts with certain of these commercial vehicle OEMs and other large volume customers, who have substantial bargaining power with respect to price and other commercial terms, and any long-term contracts would be subject to renegotiation and renewal from time to time. Failure to obtain new customers, loss of all or a substantial portion of sales to any future customers for whatever reason (including, but not limited to, loss of contracts or failure to negotiate acceptable terms in contract renewal negotiations, loss of market share by these customers, insolvency of such customers, reduced or delayed customer requirements, plant shutdowns, strikes or other work stoppages affecting production by such customers) or continued reduction of prices to these customers could have a significant adverse effect on our financial results. There can be no assurance that we will be able to obtain large volume customers, not lose all or a portion of sales to any future large volume customers or that we will be able to offset any reduction of prices to these customers with reductions in our costs or by obtaining new customers.

The level of any future sales to commercial vehicle OEMs, including the realization of future sales from awarded business or obtaining new business or customers, is inherently subject to a number of risks and uncertainties, including the number of vehicles that these commercial vehicle OEMs actually manufacture and sell. Further, to the extent that the financial condition, including bankruptcy or market share, of any of our largest customers deteriorates or their sales otherwise continue to decline, our business, prospects, financial position and operating results could be adversely affected. Accordingly, we may not in fact realize all of the future sales represented by our awarded business. Any failure to realize these sales could have a material adverse effect on our business, prospects, financial condition and operating results.

We are dependent on our suppliers, some of which are single or limited source suppliers, and the inability of these suppliers to deliver necessary components of our vehicles at prices and volumes, performance and specifications acceptable to us could have a material adverse effect on our business, prospects, financial condition and operating results.

We rely on third-party suppliers for the provision and development of many of the key components and materials used in our electrified powertrain solutions, such as natural gas generators. While we plan to obtain components from multiple sources whenever possible, some of the components used in our vehicles will be purchased by us from a single source. Our third-party suppliers may not be able to meet their product specifications and performance characteristics or our desired specifications, performance and pricing, which would impact our ability to achieve our product specifications and performance characteristics as well. Additionally, our third-party suppliers may be unable to obtain required certifications for their products for which we plan to use or provide warranties that are necessary for our solutions. If we are unable to obtain components and materials used in our electrified powertrain solutions from our suppliers or if our suppliers decide to create or supply a competing product, our business could be adversely affected. Additionally, we have entered into a commercial matters agreement with Dana Limited (“Dana”), pursuant to which we agreed to exclusively purchase from Dana

Table of Contents

and our affiliates, unless we are directed by a customer to use a different vendor, any component, product or service required or utilized by us that Dana or any of our affiliates manufactures, sells or provides so long as Dana or any of our affiliates are capable and willing to supply or provide a reasonably competitive component, product or service to us on reasonably competitive terms and conditions. While we believe that we may be able to establish alternate supply relationships and can obtain or engineer replacement components for our single source components, we may be unable to do so in the short term (or at all) at prices or quality levels that are favorable to us, which could have a material adverse effect on our business, prospects, financial condition and operating results.

Our future growth is dependent upon the commercial trucking industry’s willingness to adopt alternative fuel, hybrid and electric vehicles.

Our growth is highly dependent upon the adoption of alternative fuel, hybrid and electric vehicles by the commercial trucking industry. If the market for alternative fuel, hybrid and electric vehicles and our electrified powertrain solutions does not develop at the rate or in the manner or to the extent that we expect, or if critical assumptions we have made regarding the efficiency of our electrified powertrain solutions are incorrect or incomplete, our business, prospects, financial condition and operating results will be harmed. The market for alternative fuels, hybrid and electric vehicles is new and untested and is characterized by rapidly changing technologies, price competition, numerous competitors, evolving government regulation and industry standards and uncertain customer demands and behaviors.

Factors that may influence the adoption of alternative fuel, hybrid and electric vehicles include:

• perceptions about alternative fuel, hybrid and electric vehicle quality, safety, design, performance, reliability and cost, especially if adverse events or accidents occur that are linked to the quality or safety of alternative fuel, hybrid or electric vehicles;

• perceptions about vehicle safety in general, including the use of advanced technology, such as vehicle electronics, alternative fuel and regenerative braking systems;

• the decline of vehicle efficiency resulting from deterioration over time in the ability of the battery to hold a charge;

• changes or improvements in the fuel economy of internal combustion engines, the vehicle and the vehicle controls or competitors’ electrified systems;

• the availability of service and associated costs for alternative fuel, hybrid or electric vehicles;

• volatility in the cost of energy, oil, gasoline, natural gas, hydrogen and renewable fuels could affect buying decisions, which could affect the carbon profile of our solutions;

• the availability of refueling stations, particularly compressed natural gas (“CNG”) stations;

• government regulations and economic incentives promoting fuel efficiency and alternate forms of energy, including new regulations mandating zero tailpipe emissions compared to overall carbon reduction;

• the availability of tax and other governmental incentives to purchase and operate alternative fuel, hybrid and electric vehicles or future regulation requiring increased use of nonpolluting trucks;

• the availability of rebates provided by natural gas fueling stations and natural gas providers to offset the costs of natural gas and natural gas vehicles;

• the ability of Hyliion, fleets, utilities and others to purchase and take credit for renewable fuel and energy, specifically RNG, through low carbon fuel standards (“LCFS”) programs or similar programs that take advantage of RNG credits in approved states;

• the availability of tax and other governmental incentives to sell natural gas;

• perceptions about and the actual cost of alternative fuel itself, as well as hybrid and electric vehicles; and

• macroeconomic factors.

For example, the market price of oil has dropped since March 2020, and it is unknown to what extent any corresponding decreases in the cost of diesel fuel may impact the market for electric vehicles. Moreover, travel restrictions and social distancing efforts in response to the COVID-19 pandemic may negatively impact the commercial trucking industry, such as reduced consumer demand for products carried by the commercial trucking industry, for an unknown, but potentially lengthy, period of time. Additionally, we may become subject to regulations that may require us to alter the design of our electrified powertrain solutions, which could negatively impact customer interest in our products.

Although we hope to be the first to bring electrified powertrain solutions to market, competitors have already displayed electrified vehicle prototypes and may enter the market before us.

We face intense competition in trying to be the first to bring our electrified powertrain solutions to market. Most of our current and potential competitors have greater financial, technical, manufacturing, marketing and other resources than we do. They may be able to deploy greater resources to the design, development, manufacturing, distribution, promotion, sales, marketing and support of their alternative fuel and electric truck programs. Additionally, our competitors also have greater name recognition, longer operating histories, larger sales forces, broader customer and industry relationships and other resources than we do. These competitors also compete with us in recruiting and retaining qualified research and development, sales, marketing and management personnel, as well as in acquiring technologies complementary to, or necessary for, our products. Additional mergers and acquisitions may result in even more resources being concentrated in our competitors. We cannot provide assurances that our electrified systems will be the first to market. Even if our electrified systems are first to market, there are no assurances that customers will choose vehicles with our electrified systems over those of our competitors, or over diesel powered trucks.

Tesla, Inc. (“Tesla”) and Nikola Corporation (“Nikola”) have announced their plans to bring Class 8 long haul battery electric vehicles (“BEVs”) and fuel cell electric vehicles (“FCEVs”) to the market over the coming years. Tesla announced its BEV and Nikola announced its plug-in BEVs. Cummins Inc. (“Cummins”), Daimler AG (“Daimler”), parent of Freightliner Trucks, Dana, Navistar International Corporation (“Navistar”), PACCAR Inc. (“PACCAR”), parent of Kenworth Trucks, Inc. and Peterbilt Motors Company, Volvo Group (“Volvo”), XOS Trucks (“XOS”) and other commercial vehicle manufacturers have announced their plans to bring Class 8 BEVs or FCEVs to the market. Furthermore, we will also face competition from manufacturers of internal combustion engines powered by diesel fuel. We expect additional competitors to enter the industry as well.

We expect competition in our industry to intensify from our existing and future competitors in the future in light of increased demand and regulatory push for alternative fuel and electric vehicles.

The unavailability, reduction or elimination of government and economic incentives due to policy changes or government regulation could have a material adverse effect on our business, prospects, financial condition and operating results.

Any reduction, elimination or discriminatory application of government subsidies and economic incentives because of policy changes, the reduced need for such subsidies and incentives due to the perceived success of the electric vehicle industry or other reasons may result in the diminished competitiveness of the alternative fuel and electric vehicle industry generally or our electrified powertrain solutions. While certain tax credits and other incentives for alternative energy production, alternative fuel and electric vehicles have been available in the past, there is no guarantee these programs will be available in the future. If current tax incentives are not available in the future, our financial position could be harmed.

In particular, we are influenced by federal, state and local tax credits, rebates, grants and other government programs and incentives that promote the use of RNG and natural gas as a vehicle fuel. These include various government programs that make grant funds available for the purchase of natural gas vehicles, as well as D3 RIN and LCFS programs, which encourage low carbon “compliant” transportation fuels (including CNG) in the California and Oregon marketplace by allowing producers of these fuels to generate LCFS Credits that can be sold to noncompliant regulated parties and the Alternative Fuel Tax Credit (“AFTC”) under which a tax credit is available for natural gas vehicle fuel sales made through the end of 2020 but which may not be available for vehicle fuel sales made after December 31, 2020, particularly if other legislative priorities result in insufficient focus on this program during upcoming congressional sessions. Additionally, we are influenced by laws, rules and regulations

Table of Contents

that require reductions in carbon emissions or the use of renewable fuels, such as the California Low Carbon Fuel Standards and the Oregon Clean Fuels Program. These programs and regulations, which have the effect of encouraging the use of natural gas as a vehicle fuel, could expire or be repealed or amended for a variety of reasons. For example, parties with an interest in gasoline and diesel, electric or other alternative vehicles or vehicle fuels, including lawmakers, regulators, policymakers, environmental or advocacy organizations, OEMs, trade groups, suppliers or other powerful groups, may invest significant time and money in efforts to delay, repeal or otherwise negatively influence regulations and programs that promote natural gas. Many of these parties have substantially greater resources and influence than we do. Further, changes in federal, state or local political, social or economic conditions, including a lack of legislative focus on these programs and regulations, could result in their modification, delayed adoption or repeal. Any failure to adopt, delay in implementation, expiration, repeal or modification of these programs and regulations, or the adoption of any programs or regulations that encourage the use of other alternative fuels or alternative vehicles over natural gas, would reduce the market for natural gas as a vehicle fuel and harm our operating results, liquidity and financial condition. For instance, California lawmakers and regulators have implemented various measures designed to increase the use of electric, hydrogen and other zero-emission vehicles, including establishing firm goals for the number of these vehicles operating on state roads by specified dates and enacting various laws and other programs in support of these goals. Although the influence and applicability of these or similar measures on our business and natural gas vehicle adoption in general remains uncertain, a focus by these groups on zero tailpipe emissions vehicles over vehicles with an overall net carbon negative emissions profile, but with some tailpipe emissions operating on RNG, could adversely affect the market for natural gas vehicles, including those powered by our electrified powertrain solutions. If these economic incentives are reduced or eliminated, there could be a reduction of the supply of natural gas, a corresponding increase in the price of natural gas, and our electrified powertrain solutions may not be net carbon negative, which could have a material adverse effect on our business, prospects, financial condition and operating results.

Additionally, other changes to governmental regulations and policies could impact the competitiveness of natural gas as a fuel source. For instance, a limitation or ban on extraction methods like fracking, could have a negative impact on the availability and price of natural gas and may adversely affect the growth of the alternative fuel automobile markets. Additionally, an increase in the economic incentives for other fuel sources or BEVs, such as through the subsidization of other fuel sources or higher permitted weight limits for BEVs or FCEVs or the reduction or elimination of the higher permitted weight limits for natural gas vehicles, could make our products less competitive. Such changes in regulations and policies could materially and adversely affect our business, prospects, financial condition and operating results.

Our business could be negatively affected by unfavorable changes to federal or state tax laws or the adoption of federal or state laws or regulations mandating new or additional limits on the production of GHG emissions, the cost of natural gas and “tailpipe” emissions.

Federal or state laws or regulations may be adopted that would impose new or additional limits on the emissions of GHG. The potential effects of GHG emission limits on our business are subject to significant uncertainties based on, among other things, the timing of the implementation of any new requirements, the required levels of emission reductions, the nature of any market-based or tax-based mechanisms adopted to facilitate reductions, the relative availability of GHG emission reduction offsets, the development of cost-effective, commercial-scale carbon capture and storage technology and supporting regulations and liability mitigation measures, the range of available compliance alternatives, and our ability to demonstrate that our products qualify as a compliance alternative under any new statutory or regulatory programs to limit GHG emissions. If our solutions are not able to meet future GHG emission limits or perform as well as BEV, FCEV or other alternative fuel vehicles, for instance due to unavailability of RNG in a particular area or a decline in RNG production or an increase in our cost, our solutions could be less competitive. Additionally, federal, state or road taxes could be added to natural gas fuel, which would increase the operating cost of our products. Furthermore, additional federal or state taxes could be implemented on “tailpipe” emissions, which would have a negative impact on the cost of our products and a positive impact on the cost of BEVs and FCEVs relative to our solutions. Such new federal or state laws or regulations could have a material adverse impact on our business, prospects, financial condition and operating results.

We, our outsourcing partners and our suppliers are or may be subject to substantial regulation and unfavorable changes to, or failure by us, our outsourcing partners or our suppliers to comply with, these regulations could substantially harm our business and operating results.

Our electrified powertrain solutions, and the sale of motor vehicles in general, our outsourcing partners and our suppliers are or may be subject to substantial regulation under international, federal, state and local laws. We continue to evaluate requirements for licenses, approvals, certificates and governmental authorizations necessary to manufacture, sell or service our electrified powertrain solutions in the jurisdictions in which we plan to operate and intend to take such actions necessary to comply. We may experience difficulties in obtaining or complying with various licenses, approvals, certifications and other governmental authorizations necessary to manufacture, sell or service their electrified powertrain solutions in any of these jurisdictions. For instance, our electrified powertrain solutions are novel technology that may not be readily classified into categories by governmental agencies. If we, our outsourcing partners or our suppliers are unable to obtain or comply with any of the licenses, approvals, certifications or other governmental authorizations necessary to carry out our operations in the jurisdictions in which we currently operate, or those jurisdictions in which we plan to operate in the future, our business, prospects, financial condition and operating results could be materially adversely affected. We expect to incur significant costs in complying with these regulations. For example, if the battery packs installed in our electrified powertrain solutions are deemed to be transported, we will need to comply with the mandatory regulations governing the transport of “dangerous goods,” and any deficiency in compliance may result in us being prohibited from selling our electrified powertrain solutions until compliant batteries are installed. Additionally, although we do not believe that our Hybrid system is required to obtain certifications from the EPA and the California Air Resources Board (“CARB”), in the event that regulators determine that certifications are necessary, we may be prohibited from selling our Hybrid system until such time as we obtain the required certifications. Any such required changes to our battery packs or Hybrid system will require additional expenditures and may delay the shipment of vehicles. In addition, regulations related to the electric and alternative energy vehicle industry are evolving and we face risks associated with changes to these regulations, including but not limited to:

• increased subsidies for corn and ethanol production, which could reduce the operating cost of vehicles that use ethanol or a combination of ethanol and gasoline;

• increased support for other alternative fuel systems, which could have an impact on the acceptance of our electric powertrain system; and

• increased sensitivity by regulators to the needs of established automobile manufacturers with large employment bases, high fixed costs and business models based on the internal combustion engine, which could lead them to pass regulations that could reduce the compliance costs of such established manufacturers or mitigate the effects of government efforts to promote alternative fuel vehicles.

To the extent the laws change, our electrified powertrain solutions and our suppliers’ products may not comply with applicable international, federal, state or local laws, which would have an adverse effect on our business. Compliance with changing regulations could be burdensome, time consuming and expensive. To the extent compliance with new regulations is cost prohibitive, our business, prospects, financial condition and operating results would be adversely affected.

If our electrified powertrain solutions fail to perform as expected, our ability to develop, market and sell our electrified powertrain solutions could be harmed.

Our electrified powertrain solutions may contain defects in design and production that may cause them not to perform as expected or may require repair. We currently have a limited frame of reference by which to evaluate the performance of our electrified powertrain solutions upon which our business prospects depend. There can be no assurance that we will be able to detect and fix any defects in our electrified powertrain solutions. We may experience recalls in the future, which could adversely affect our brand and could adversely affect our business, prospects, financial condition and operating results. Our electrified powertrain solutions may not perform consistent with customers’ expectations or consistent with other vehicles which may become available. Any product defects or any other failure of our electrified powertrain solutions and software to perform as expected could harm our reputation and result in adverse publicity, lost revenue, delivery delays, product recalls, negative publicity, product liability claims and significant warranty and other expenses and could have a material adverse impact on our

Table of Contents

business, prospects, financial condition and operating results. Additionally, problems and defects experienced by other alternative fuel truck companies or electric consumer vehicles could by association have a negative impact on perception and customer demand for our electrified powertrain solutions.

We may become subject to product liability claims, which could harm our financial condition and liquidity if we are not able to successfully defend or insure against such claims.

Product liability claims, even those without merit or those that do not involve our products, could harm our business, prospects, financial condition and operating results. The automobile industry in particular experiences significant product liability claims, and we face inherent risk of exposure to claims in the event our electric powertrain solutions do not perform or are claimed to not have performed as expected. As is true for other commercial vehicle suppliers, we expect in the future that our electrified powertrain solutions will be installed on vehicles that will be involved in crashes resulting in death or personal injury. Additionally, product liability claims that affect our competitors may cause indirect adverse publicity for us and our products.

A successful product liability claim against us could require us to pay a substantial monetary award. Our risks in this area are particularly pronounced given the relatively limited number of electrified powertrain solutions delivered to date and limited field experience of our products. Moreover, a product liability claim against us or our competitors could generate substantial negative publicity about our products and business and could have a material adverse effect on our brand, business, prospects, financial condition and operating results. In most jurisdictions, we generally self-insure against the risk of product liability claims for vehicle exposure, meaning that any product liability claims will likely have to be paid from company funds, not by insurance.

Our electrified powertrain solutions rely on software and hardware that is highly technical, and if these systems contain errors, bugs or vulnerabilities, or if we are unsuccessful in addressing or mitigating technical limitations in our systems, our business could be adversely affected.

Our electrified powertrain solutions rely on software and hardware, including software and hardware developed or maintained internally or by third parties, that is highly technical and complex and will require modification and updates over the life of the vehicle. In addition, our electrified powertrain solutions depend on the ability of such software and hardware to store, retrieve, process and manage immense amounts of data. Our software and hardware may contain, errors, bugs or vulnerabilities, and our systems are subject to certain technical limitations that may compromise our ability to meet our objectives. Some errors, bugs or vulnerabilities inherently may be difficult to detect and may only be discovered after the code has been released for external or internal use. Errors, bugs, vulnerabilities, design defects or technical limitations may be found within our software and hardware. Although we attempt to remedy any issues we observe in our products as effectively and rapidly as possible, such efforts may not be timely, may hamper production or may not be to the satisfaction of our customers. Additionally, if we are able to deploy updates to the software addressing any issues but our over-the-air update procedures fail to properly update the software, our customers would then be responsible for installing such updates to the software and their software will be subject to these vulnerabilities until they do so. If we are unable to prevent or effectively remedy errors, bugs, vulnerabilities or defects in our software and hardware, we may suffer damage to our reputation, loss of customers, loss of revenue or liability for damages, any of which could adversely affect our business and financial results.

If we are unable to establish and maintain confidence in our long-term business prospects among customers and analysts and within our industry or are subject to negative publicity, then our financial condition, operating results, business prospects and access to capital may suffer materially.

Customers may be less likely to purchase our electric powertrain solutions if they are not convinced that our business will succeed or that our service and support and other operations will continue in the long term. Similarly, suppliers and other third parties will be less likely to invest time and resources in developing business relationships with is if they are not convinced that our business will succeed. Accordingly, in order to build and maintain our business, we must maintain confidence among customers, suppliers, analysts, ratings agencies and other parties in our products, long-term financial viability and business prospects. Maintaining such confidence may be particularly complicated by certain factors including those that are largely outside of our control, such as our limited operating history, customer unfamiliarity with our electric powertrain solutions, any delays in scaling production, delivery and service operations to meet demand, competition and uncertainty regarding the future of hybrid electric and electric vehicles or our other services and our production and sales performance compared with market expectations.

Developments in alternative technology or improvements in the internal combustion engine may adversely affect the demand for our electrified powertrain solutions.

Significant developments in alternative technologies, such as battery cell technology, advanced diesel, ethanol or natural gas, or improvements in the fuel economy of the internal combustion engine, may materially and adversely affect our business, prospects, financial condition and operating results in ways we do not currently anticipate. Existing and other battery cell technologies, fuels or sources of energy may emerge as customers’ preferred alternative to our electrified powertrain solutions. Any failure by us to develop new or enhanced technologies or processes, or to react to changes in existing technologies, could materially delay our development and introduction of new and enhanced alternative fuel and electric vehicles, which could result in the loss of competitiveness of our electrified powertrain solutions, decreased revenue and a loss of market share to competitors. Our research and development efforts may not be sufficient to adapt to changes in alternative fuel and electric vehicle technology. As technologies change, we plan to upgrade or adapt our electrified powertrain solutions with the latest technology, in particular battery cell technology, which may also negatively impact the adoption of other our products. However, our electrified powertrain solutions may not compete effectively with alternative systems if we are not able to source and integrate the latest technology into our electrified powertrain solutions.

We have limited experience servicing our electrified powertrain solutions and our integrated software. If we are unable to address the service requirements of our customers, our business, prospects, financial condition and operating results may be materially and adversely affected.

We have limited experience in servicing our electrified powertrain solutions and expect to increase our servicing capabilities as we begin commercial production of our electrified powertrain solutions. Servicing hybrid and electric vehicles is different than servicing vehicles with internal combustion engines and requires specialized skills, including high voltage training and servicing techniques. We plan to partner with a third party to perform some or all of the servicing on our electrified powertrain solutions, and there can be no assurance that we will be able to enter into an acceptable arrangement with any such third-party provider. Our customers will also depend on our customer support team to resolve technical and operational issues relating to the integrated software underlying our electrified powertrain solutions. Our ability to provide effective customer support is largely dependent on our ability to attract, train and retain qualified personnel with experience in supporting customers on platforms such as ours. As we continue to grow, additional pressure may be placed on our customer support team, and we may be unable to respond quickly enough to accommodate short-term increases in customer demand for technical support. We also may be unable to modify the future scope and delivery of our technical support to compete with changes in the technical support provided by our competitors. Increased customer demand for support, without corresponding revenue, could increase costs and negatively affect our operating results. If we are unable to successfully address the service requirements of our customers or establish a market perception that we do not maintain high-quality support, we may be subject to claims from our customers, including loss of revenue or damages, and our business, prospects, financial condition and operating results may be materially and adversely affected.

In addition, the motor vehicle industry laws in many states require that service facilities be available to service vehicles physically sold from locations in their state. While we anticipate developing a service program that would satisfy regulators in these circumstances, the specifics of our service program are still in development, and at some point may need to be restructured to comply with state law, which may impact our business, prospects, financial condition and operating results.

We are highly dependent on the services of Thomas Healy, our Chief Executive Officer, and if we are unable to retain Mr. Healy, attract and retain key employees and hire qualified management, technical and vehicle engineering personnel, our ability to compete could be harmed.

Our success depends, in part, on our ability to retain our key personnel. We are highly dependent on the services of Thomas Healy, our Chief Executive Officer, and largest stockholder. Mr. Healy is the source of many, if not most, of the ideas and execution driving us. If Mr. Healy were to discontinue his service to us due to death, disability or any other reason, we would be significantly disadvantaged. The unexpected loss of or failure to retain one or more of our key employees could adversely affect our business.

Our success also depends, in part, on our continuing ability to identify, hire, attract, train and develop other highly qualified personnel, in particular software engineers. Experienced and highly skilled employees are in high demand and competition for these employees can be intense, and our ability to hire, attract and retain them depends

Table of Contents

on our ability to provide competitive compensation. We may not be able to attract, assimilate, develop or retain qualified personnel in the future, and our failure to do so could adversely affect our business, including the execution of our global business strategy. We do not currently maintain key man life insurance policies with respect to Thomas Healy or any other officer and we will continue to evaluate whether to obtain such key man life insurance policies. Any failure by our management team and our employees to perform as expected may have a material adverse effect on our business, prospects, financial condition and operating results.

We face significant barriers to produce our electrified powertrain solutions, and if we cannot successfully overcome those barriers our business will be negatively impacted.

The commercial trucking industry has traditionally been characterized by significant barriers to entry, including the ability to meet performance requirements or industry specifications, acceptance by OEMs and our end users, large capital requirements, investment costs of design and production, long lead times to bring components to market from the concept and design stage, the need for specialized design and development expertise, regulatory requirements, establishing a brand name and image and the need to establish sales capabilities. If we are not able to overcome these barriers, our business, prospects, financial condition and operating results will be negatively impacted and our ability to grow our business will be harmed.

Future product recalls could materially adversely affect our business, prospects, financial condition and operating results.

Any product recall in the future, whether it involves us or a competitor’s product, may result in negative publicity, damage our brand and materially adversely affect our business, prospects, financial condition and operating results. In the future, we may voluntarily or involuntarily, initiate a recall if any of our products (including the batteries we design, develop and manufacture) prove to be defective or noncompliant with applicable federal motor vehicle safety standards. Such recalls involve significant expense and diversion of management attention and other resources, which could adversely affect our brand image, as well as our business, prospects, financial condition and operating results.

Insufficient warranty reserves to cover future warranty claims could materially adversely affect our business, prospects, financial condition and operating results.

Once we begin commercial production of our electrified powertrain solutions, we will need to maintain warranty reserves to cover warranty-related claims. If our warranty reserves are inadequate to cover future warranty claims on our vehicles, our business, prospects, financial condition and operating results could be materially and adversely affected. We may become subject to significant and unexpected warranty expenses as well as claims from our customers, including loss of revenue or damages. There can be no assurances that then-existing warranty reserves will be sufficient to cover all claims.

Increases in costs, disruption of supply or shortage of our components, particularly lithium titanate oxide (“LTO”) battery cells, could harm our business.

Once we begin commercial production of our electrified powertrain solutions, we may experience increases in the cost or a sustained interruption in the supply or shortage of our components. Any such increase or supply interruption could materially negatively impact our business, prospects, financial condition and operating results. The prices for our components fluctuate depending on market conditions and global demand and could adversely affect our business, prospects, financial condition and operating results. For instance, we are exposed to multiple risks relating to price fluctuations for LTO cells. These risks include:

• the inability or unwillingness of current battery manufacturers to build or operate battery cell production facilities to supply the numbers of LTO cells required to support the growth of the electric vehicle industry as demand for such cells increases;

• disruption in the supply of cells due to quality issues or recalls by the battery cell manufacturers;

• a fewer number of manufacturers of LTO cells compared to lithium nickel manganese cobalt oxide (“NMC”) or lithium nickel cobalt aluminum oxide (“NCA”) cells; and

• an increase in the cost of raw materials.

Table of Contents

Any disruption in the supply of battery cells could temporarily disrupt production of our electrified powertrain solutions until a different supplier is fully qualified. Moreover, battery cell manufacturers may refuse to supply electric vehicle manufacturers if they determine that the vehicles are not sufficiently safe. Furthermore, fluctuations or shortages in petroleum and other economic conditions may cause us to experience significant increases in freight charges. Substantial increases in the prices for raw materials may increase the cost of our components and consequently, the costs of products. There can be no assurance that we will be able to recoup increasing costs of our components by increasing prices, which could reduce our margins.

We have been, and may in the future be, adversely affected by the global COVID-19 pandemic, the duration and economic, governmental and social impact of which is difficult to predict, which may significantly harm our business, prospects, financial condition and operating results.

There has been a widespread worldwide impact from the COVID-19 pandemic, and we have been, and may in the future be, adversely affected as a result. Numerous government regulations and public advisories, as well as shifting social behaviors, have temporarily limited or closed non-essential transportation, government functions, business activities and person-to-person interactions, and the duration of such trends is difficult to predict. Reduced operations and production line shutdowns at commercial vehicle OEMs due to COVID-19, limitations on travel by our personnel and personnel of our customers and increased demand for commercial trucks within our customers’ fleets caused some customers to delay the planned installation of our Hybrid system on their trucks past the second quarter of 2020, and future delays or shutdowns of commercial vehicle OEMs or our suppliers could impact our ability to meet customer orders. We also instituted certain temporary cost reduction measures such as reducing or deferring discretionary spending.

The specific timing and pace of our resumption of normal operations will depend on the status of various government regulations and the readiness of our suppliers, vendors and workforce. Although we are working to resume meetings with potential customers, we ultimately remain uncertain how we may be impacted should COVID-19 concerns increase in the future.

Our operations and timelines may also be affected by global economic markets and levels of consumer comfort and spend, which could impact demand in the worldwide transportation industries. Because the impact of current conditions on an ongoing basis is yet largely unknown, is rapidly evolving and has been varied across geographic regions, this ongoing assessment will be particularly critical to allow us to accurately project demand and infrastructure requirements globally and deploy our workforce and other resources accordingly. If current global market conditions continue or worsen, or if we cannot or do not resume reduced operations at a rate commensurate with such conditions or resume full operational capacity and are later required to or choose to reduce such operations again, our business, prospects, financial condition and operating results could be materially harmed.

Demand for our products will ultimately depend on our end users, some of whom operate in highly cyclical industries, which may subject us to the performance of their industries and can result in uncertainty and significantly impact the demand for our products, which could have a material adverse effect on our business, prospects, financial condition and operating results.

Demand for our products will ultimately depend on our end users, some of whom operate in highly cyclical industries and have felt the impact of COVID-19 and other factors on demand for output in their industries. Decisions to purchase our electrified powertrain solutions may depend on the performance of the industries of our end users and if demand for output in those industries decreases, the demand for our products will likely decrease. Demand in these industries is impacted by numerous factors, including commodity prices, infrastructure spending, housing starts, real estate equity values, interest rates, consumer spending, fuel costs, energy demands, municipal spending and commercial construction, among others. Increases or decreases in these variables may significantly impact the demand for our products. For example, lower diesel fuel costs, higher CNG costs or lower CNG availability would reduce our products’ cost savings, which could have a material adverse effect on our business, prospects, financial condition and operating results. Additionally, some of our end users have felt the impact of the COVID-19 pandemic, which has resulted in reduced demand for commercial vehicles and may affect fueling infrastructure such as CNG stations. If we are unable to accurately predict demand, we may be unable to meet our customers’ needs, resulting in the loss of potential sales, or we may produce excess products, resulting in increased inventories and overcapacity in our contracted production facilities, increasing our unit production cost and decreasing our operating margins.

We are or may be subject to risks associated with strategic alliances or acquisitions and may not be able to identify adequate strategic relationship opportunities, or form strategic relationships, in the future.

We have entered into strategic alliances, and may in the future enter into additional strategic alliances or joint ventures or minority equity investments, in each case with various third parties for the production of our electrified powertrain solutions as well as with other collaborators with capabilities on data and analytics, engineering, installation channels, refueling stations and hydrogen fuel cells. These alliances subject us to a number of risks, including risks associated with sharing proprietary information, non-performance by the third party and increased expenses in establishing new strategic alliances, any of which may materially and adversely affect our business. We may have limited ability to monitor or control the actions of these third parties and, to the extent any of these strategic third parties suffers negative publicity or harm to their reputation from events relating to their business, we may also suffer negative publicity or harm to our reputation by virtue of our association with any such third party.

Strategic business relationships will be an important factor in the growth and success of our business. However, there are no assurances that we will be able to continue to identify or secure suitable business relationship opportunities in the future or our competitors may capitalize on such opportunities before we do. Moreover, identifying such opportunities could require substantial management time and resources, and negotiating and financing relationships involves significant costs and uncertainties. If we are unable to successfully source and execute on strategic relationship opportunities in the future, our overall growth could be impaired, and our business, prospects, financial condition and operating results could be materially adversely affected.

When appropriate opportunities arise, we may acquire additional assets, products, technologies or businesses that are complementary to our existing business. In addition to possible stockholder approval, we may need approvals and licenses from relevant government authorities for the acquisitions and to comply with any applicable laws and regulations, which could result in increased delay and costs, and may disrupt our business strategy if we fail to do so. Furthermore, acquisitions and the subsequent integration of new assets and businesses into our own require significant attention from our management and could result in a diversion of resources from our existing business, which in turn could have an adverse effect on our operations. Acquired assets or businesses may not generate the financial results we expect. Acquisitions could result in the use of substantial amounts of cash, potentially dilutive issuances of equity securities, the occurrence of significant goodwill impairment charges, amortization expenses for other intangible assets and exposure to potential unknown liabilities of the acquired business. Moreover, the costs of identifying and consummating acquisitions may be significant.

Work stoppages or similar difficulties could significantly disrupt our operations.

A work stoppage, including due to the COVID-19 pandemic, at the production facilities of one or more of our or our outsourcing partners’, suppliers and commercial vehicle OEMs could have a material adverse effect on our business. In addition, if a significant customer were to experience a work stoppage, that customer could halt or limit purchases of our products, which could result in shutting down the related production facilities. Also, a significant disruption in the supply of a key component due to a work stoppage at one of our suppliers could result in shutting down production facilities, which could have a material adverse effect on our business.

We are subject to cybersecurity risks to operational systems, security systems, infrastructure, integrated software in our electrified powertrain solutions and customer data processed by us or third-party vendors or suppliers and any material failure, weakness, interruption, cyber event, incident or breach of security could prevent us from effectively operating our business.

We are at risk for interruptions, outages and breaches of: (a) operational systems, including business, financial, accounting, product development, data processing or production processes, owned by us or our third-party vendors or suppliers; (b) facility security systems, owned by us or our third-party vendors or suppliers; (c) transmission control modules or other in-product technology, owned by us or our third-party vendors or suppliers; (d) the integrated software in our electrified powertrain solutions; or (e) customer or driver data that we process or our third-party vendors or suppliers process on our behalf. Such cyber incidents could: materially disrupt operational systems; result in loss of intellectual property, trade secrets or other proprietary or competitively sensitive information; compromise certain information of customers, employees, suppliers, drivers or others; jeopardize the security of our facilities; or affect the performance of transmission control modules or other in-product technology and the integrated software in our electrified powertrain solutions. A cyber incident could be caused by disasters,

Table of Contents

insiders (through inadvertence or with malicious intent) or malicious third parties (including nation-states or nation-state supported actors) using sophisticated, targeted methods to circumvent firewalls, encryption and other security defenses, including hacking, fraud, trickery or other forms of deception. The techniques used by cyber attackers change frequently and may be difficult to detect for long periods of time. Although we maintain information technology measures designed to protect ourselves against intellectual property theft, data breaches and other cyber incidents, such measures will require updates and improvements, and we cannot guarantee that such measures will be adequate to detect, prevent or mitigate cyber incidents. The implementation, maintenance, segregation and improvement of these systems requires significant management time, support and cost. Moreover, there are inherent risks associated with developing, improving, expanding and updating current systems, including the disruption of our data management, procurement, production execution, finance, supply chain and sales and service processes. These risks may affect our ability to manage our data and inventory, procure parts or supplies or produce, sell, deliver and service our electric powertrain solutions, adequately protect our intellectual property or achieve and maintain compliance with, or realize available benefits under, applicable laws, regulations and contracts. We cannot be sure that these systems upon which we rely, including those of our third-party vendors or suppliers, will be effectively implemented, maintained or expanded as planned. If we do not successfully implement, maintain or expand these systems as planned, our operations may be disrupted, our ability to accurately and timely report our financial results could be impaired, and deficiencies may arise in our internal control over financial reporting, which may impact our ability to certify our financial results. Moreover, our proprietary information or intellectual property could be compromised or misappropriated and our reputation may be adversely affected. If these systems do not operate as we expect them to, we may be required to expend significant resources to make corrections or find alternative sources for performing these functions.

A significant cyber incident could impact production capability, harm our reputation, cause us to breach our contracts with other parties or subject us to regulatory actions or litigation, any of which could materially affect our business, prospects, financial condition and operating results. In addition, our insurance coverage for cyberattacks may not be sufficient to cover all the losses we may experience as a result of a cyber incident.

We also collect, store, transmit and otherwise process customer, driver and employee and others’ data as part of our business and operations, which may include personal data or confidential or proprietary information. We also work with partners and third-party service providers or vendors that collect, store and process such data on our behalf and in connection with our products and services. There can be no assurance that any security measures that we or our third-party service providers or vendors have implemented will be effective against current or future security threats. While we have developed systems and processes designed to protect the availability, integrity, confidentiality and security of our and our customers’, drivers’, employees’ and others’ data, our security measures or those of our third-party service providers or vendors could fail and result in unauthorized access to or disclosure, acquisition, encryption, modification, misuse, loss, destruction or other compromise of such data. If a compromise of such data were to occur, we may become liable under our contracts with other parties and under applicable law for damages and incur penalties and other costs to respond to, investigate and remedy such an incident. Laws in all 50 states require us to provide notice to customers, regulators, credit reporting agencies and others when certain sensitive information has been compromised as a result of a security breach. Such laws are inconsistent and compliance in the event of a widespread data breach could be costly. Depending on the facts and circumstances of such an incident, these damages, penalties, fines and costs could be significant. Such an event could harm our reputation and result in litigation against us. Any of these results could materially adversely affect our business, prospects, financial condition and operating results.

Any unauthorized control or manipulation of the information technology systems in our electrified powertrain solutions could result in loss of confidence in us and our electrified powertrain solutions and harm our business.

Our electrified powertrain solutions contain complex information technology systems and built-in data connectivity to accept and install periodic remote updates to improve or update functionality. We have designed, implemented and tested security measures intended to prevent unauthorized access to our information technology networks, our electrified powertrain solutions and related systems. However, hackers may attempt to gain unauthorized access to modify, alter and use such networks, trucks and systems to gain control of or to change our electrified powertrain solutions’ functionality, user interface and performance characteristics, or to gain access to data stored in or generated by the truck. Future vulnerabilities could be identified and our efforts to remediate such vulnerabilities may not be successful. Any unauthorized access to or control of our electrified powertrain solutions, or any loss of customer data, could result in legal claims or proceedings and remediation of such problems could

Table of Contents

result in significant, unplanned capital expenditures. In addition, regardless of their veracity, reports of unauthorized access to our electrified powertrain solutions or data, as well as other factors that may result in the perception that our electrified powertrain solutions or data are capable of being “hacked,” could negatively affect our brand and harm our business, prospects, financial condition and operating results.

Inability to leverage vehicle and customer data could impact our software algorithms and impact research and development operations.

We rely on data collected from the use of fleet vehicles outfitted with our products, including vehicle data and data related to battery usage statistics. We use this data in connection with our software algorithms and the research, development and analysis of our products. Our inability to obtain this data or the necessary rights to use this data could result in delays or otherwise negatively impact our research and development efforts.

Interruption or failure of our information technology and communications systems could impact our ability to effectively provide our services.

We plan to include in-vehicle services and functionality that utilize data connectivity to monitor performance and timely capture opportunities to enhance over-the-road performance for cost-saving preventative maintenance. The availability and effectiveness of our services depend on the continued operation of information technology and communications systems. Our systems will be vulnerable to damage or interruption from, among others, physical theft, fire, terrorist attacks, natural disasters, power loss, war, telecommunications failures, viruses, denial or degradation of service attacks, ransomware, social engineering schemes, insider theft or misuse or other attempts to harm our systems. We utilize reputable third-party service providers or vendors for all of our data other than our source code, and these providers could also be vulnerable to harms similar to those that could damage our systems, including sabotage and intentional acts of vandalism causing potential disruptions. Some of our systems will not be fully redundant, and our disaster recovery planning cannot account for all eventualities. Any problems with our third-party cloud hosting providers could result in lengthy interruptions in our business. In addition, our in-vehicle services and functionality are highly technical and complex technology which may contain errors or vulnerabilities that could result in interruptions in our business or the failure of our systems.

We are subject to evolving laws, regulations, standards and contractual obligations related to data privacy and security, and our actual or perceived failure to comply with such obligations could harm our reputation, subject us to significant fines and liability or adversely affect our business.

We intend to use our in-vehicle services and functionality to log information about each vehicle’s use in order to aid us in vehicle diagnostics and servicing. Our customers or their drivers may object to the use of this data, which may increase our vehicle maintenance costs and harm our business prospects. Collection of our customers’, employees’ and others’ information in conducting our business may subject us to various legislative and regulatory burdens related to data privacy and security that could require notification of data breaches, restrict our use of such information and hinder our ability to acquire new customers or market to existing customers. The regulatory framework for data privacy and security is rapidly evolving, and we may not be able to monitor and react to all developments in a timely manner. For example, California requires connected devices to maintain minimum information security requirements. As legislation continues to develop, we will likely be required to expend significant additional resources to continue to modify or enhance our protective measures and internal processes to comply with such legislation. In addition, non-compliance with these laws or a significant breach of our third-party service providers’ or vendors’ or our own network security and systems could have serious negative consequences for our business and future prospects, including possible fines, penalties and damages, reduced customer demand for our vehicles and harm to our reputation and brand.

We are subject to various environmental laws and regulations that could impose substantial costs upon us and cause delays in building our production facilities.

Our operations are and will be subject to international, federal, state and local environmental laws and regulations, including laws relating to the use, handling, storage, disposal of and human exposure to hazardous materials. Environmental and health and safety laws and regulations can be complex, and we have limited experience complying with them. Moreover, we expect that we will be affected by future amendments to such laws or other new environmental and health and safety laws and regulations which may require us to change our operations, potentially

Table of Contents

resulting in a material adverse effect on our business, prospects, financial condition and operating results. These laws can give rise to liability for administrative oversight costs, cleanup costs, property damage, bodily injury, fines and penalties. Capital and operating expenses needed to comply with environmental laws and regulations can be significant, and violations may result in substantial fines and penalties, third-party damages, suspension of production or a cessation of our operations.

Contamination at properties we will own or operate, we formerly owned or operated or to which hazardous substances were sent by us, may result in liability for us under environmental laws and regulations, including, but not limited to, the Comprehensive Environmental Response, Compensation and Liability Act, which can impose liability for the full amount of remediation-related costs without regard to fault, for the investigation and cleanup of contaminated soil and ground water, for building contamination and impacts to human health and for damages to natural resources. The costs of complying with environmental laws and regulations and any claims concerning noncompliance, or liability with respect to contamination in the future, could have a material adverse effect on our financial condition or operating results. We may face unexpected delays in obtaining the required permits and approvals in connection with our planned production facilities that could require significant time and financial resources and delay our ability to operate these facilities, which would adversely impact our business, prospects, financial condition and operating results.

Our beliefs regarding the ability of our electrified powertrain solutions to limit carbon intensity and reduce GHG emissions and contribute to global decarbonization may be based on materially inaccurate assumptions.

We believe that our electrified powertrain solutions, to the extent adopted, may have the ability to limit carbon intensity and reduce GHG emissions from trucking operations, however, these beliefs are based on certain assumptions, including, but not limited to, our projections of the extent of natural gas and renewable natural gas use in the future, fuel types used, the ability to obtain carbon credits and driver behavior and our electrified powertrain solutions’ efficiencies and performance. To the extent our assumptions are materially incorrect or incomplete, it could adversely impact our business, prospects, financial condition and operating results. In addition, if our assumptions regarding the ability of our solutions to limit carbon intensity and reduce GHG emissions from trucking operations are materially incorrect or incomplete, or if our beliefs regarding the availability of our products are materially incorrect or incomplete, it is possible that our competitors’ technology may be better at limiting carbon intensity and reducing GHG emissions in certain circumstances and in certain markets.

We will incur increased costs as a result of operating as a public company, and our management will devote substantial time to new compliance initiatives.

As a result of operating as a public company, we will incur significant legal, accounting and other expenses that we did not incur as a private company, and these expenses may increase even more after we are no longer an emerging growth company, as defined in Section 2(a) of the Securities Act. As a public company, we are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as rules adopted, and to be adopted, by the SEC and the NYSE. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, we expect these rules and regulations to substantially increase our legal and financial compliance costs and to make some activities more time-consuming and costly. The increased costs will increase our net loss. For example, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be forced to accept reduced policy limits or incur substantially higher costs to maintain the same or similar coverage. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers.

Our management has limited experience in operating a public company.

Our executive officers have limited experience in the management of a publicly traded company. Our management team may not successfully or effectively manage our transition to a public company that is subject to significant regulatory oversight and reporting obligations under federal securities laws. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage in that it is likely that an increasing amount of their time may be devoted to these activities which will result in less

Table of Contents

time being devoted to the management and growth of our business. We may not have adequate personnel with the appropriate level of knowledge, experience and training in the accounting policies, practices or internal control over financial reporting required of public companies in the U.S. We are in the process of upgrading our finance and accounting systems to an enterprise system suitable for a public company, and a delay could impact our ability or prevent us from timely reporting our operating results, timely filing required reports with the SEC and complying with Section 404 of the Sarbanes-Oxley Act. The development and implementation of the standards and controls necessary for us to achieve the level of accounting standards required of a public company in the U.S. may require costs greater than expected. It is possible that we will be required to expand our employee base and hire additional employees to support our operations as a public company which will increase our operating costs in future periods.

Our employees and independent contractors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have an adverse effect on our business, prospects, financial condition and operating results.

We are exposed to the risk that our employees and independent contractors may engage in misconduct or other illegal activity. Misconduct by these parties could include intentional, reckless or negligent conduct or other activities that violate laws and regulations, including production standards, U.S. federal and state fraud, abuse, data privacy and security laws, other similar non-U.S. laws or laws that require the true, complete and accurate reporting of financial information or data. It is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. In addition, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, prospects, financial condition and operating results, including, without limitation, the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, disgorgement, integrity oversight and reporting obligations to resolve allegations of non-compliance, imprisonment, other sanctions, contractual damages, reputational harm, diminished profits and future earnings and curtailment of our operations, any of which could adversely affect our business, prospects, financial condition and operating results.

Changes in laws or regulations and U.S. trade policy, including the imposition of tariffs and the resulting consequences, could adversely affect our business, prospects, financial condition and operating results.

We are subject to laws and regulations enacted by national, regional and local governments and agencies. Compliance with, and monitoring of, applicable laws and regulations may be difficult, time consuming and costly. Those laws and regulations and their interpretation and application may also change from time to time and those changes could have a material adverse effect on our products and business. In addition, a failure to comply with applicable laws or regulations, as interpreted and applied, could have a material adverse effect on our business and results of operations.

The U.S. government has adopted a new approach to trade policy and in some cases has attempted to renegotiate or terminate certain existing bilateral or multi-lateral trade agreements. It has also imposed tariffs on certain foreign goods, including steel and certain commercial vehicle parts, which have begun to result in increased costs for goods imported into the U.S. In response to these tariffs, a number of U.S. trading partners have imposed retaliatory tariffs on a wide range of U.S. products, which makes it more costly for us to export our products to those countries. If we are unable to pass price increases on to our customer base or otherwise mitigate the costs, or if demand for our exported products decreases due to the higher cost, our operating results could be materially adversely affected. In addition, further tariffs have been proposed by the U.S. and our trading partners and additional trade restrictions could be implemented on a broader range of products or raw materials. The resulting environment of retaliatory trade or other practices could have a material adverse effect on our business, prospects, financial condition, operating results, customers, suppliers and the global economy.

We intend in the future to expand internationally and will face risks associated with our international operations, including unfavorable regulatory, political, tax and labor conditions, which could harm our business.

We will face risks associated with our future international operations, including possible unfavorable regulatory, political, tax and labor conditions, which could harm our business. We anticipate having international operations which would subject us to the legal, political, regulatory and social requirements and economic conditions in any future jurisdictions. Additionally, as part of our growth strategy, we intend to expand our sales and servicing services internationally. However, we have no experience to date selling and servicing our electrified powertrain solutions internationally and such expansion would require us to make significant expenditures, including the hiring of local employees and establishing facilities, in advance of generating any revenue. We are subject to a number of risks associated with international business activities that may increase our costs, impact our ability to sell our electrified powertrain solutions and require significant management attention. These risks include:

• conforming our electrified powertrain solutions to various international regulatory requirements where our electrified powertrain solutions are sold, or homologation;

• difficulties in obtaining or complying with various licenses, approvals, certifications and other governmental authorizations necessary to manufacture, sell or service our electrified powertrain solutions in any of these jurisdictions;

• difficulty in staffing and managing foreign operations;

• difficulties attracting customers in new jurisdictions;

• difficulties establishing new partnerships, including with respect to installation centers, assembly facilities, suppliers and the truck OEMs necessary to install our technology in vehicles;

• foreign government taxes, regulations and permit requirements, including foreign taxes that We may not be able to offset against taxes imposed upon we in the U.S., and foreign tax and other laws limiting our ability to repatriate funds to the U.S.;

• fluctuations in foreign currency exchange rates and interest rates, including risks related to any interest rate swap or other hedging activities we undertakes;

• U.S. and foreign government trade restrictions, tariffs and price or exchange controls;

• foreign labor laws, regulations and restrictions;

• changes in diplomatic and trade relationships;

• political instability, natural disasters, global health concerns, including health pandemics such as the COVID-19 pandemic, war or events of terrorism; and

• the strength of international economies.

If we fail to successfully address these risks, our business, prospects, financial condition and operating results could be materially harmed.

We are subject to U.S. and foreign anti-corruption and anti-money laundering laws and regulations. We can face criminal liability and other serious consequences for violations, which can harm our business.

We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act and possibly other anti-bribery and anti-money laundering laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, contractors and other collaborators from authorizing, promising, offering or providing, directly or indirectly, improper payments or anything else of value to recipients in the public or private sector. We can be held liable for the corrupt or other illegal activities of our employees, agents, contractors and other collaborators, even if we do not explicitly authorize or have actual knowledge of such activities. Any violations of the laws and regulations described above may result in substantial civil and criminal fines and penalties, imprisonment, the loss of export or import privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm and other consequences.

Table of Contents

We are subject to governmental export and import control laws and regulations. Our failure to comply with these laws and regulations could have an adverse effect on our business, prospects, financial condition and operating results.

Our products and solutions are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Control. U.S. export control laws and regulations and economic sanctions prohibit the shipment of certain products and services to U.S. embargoed or sanctioned countries, governments and persons. In addition, complying with export control and sanctions regulations for a particular sale may be time-consuming and result in the delay or loss of sales opportunities. Exports of our products and technology must be made in compliance with these laws and regulations. If we fail to comply with these laws and regulations, we and certain of our employees could be subject to substantial civil or criminal penalties, including the possible loss of export or import privileges, fines, which may be imposed on us and responsible employees or managers and, in extreme cases, the incarceration of responsible employees or managers.

In addition, changes in our products or solutions or changes in applicable export or import laws and regulations may create delays in the introduction and sale of our products and solutions in international markets, increase costs due to changes in import and export duties and taxes, prevent our customers from deploying our products and solutions or, in some cases, prevent the export or import of our products and solutions to certain countries, governments or persons altogether. Any change in export or import laws and regulations, shift in the enforcement or scope of existing laws and regulations, or change in the countries, governments, persons or technologies targeted by such laws and regulations, could also result in decreased use of our products and solutions or in our decreased ability to export or sell our products and solutions to customers. Any decreased use of our products and solutions or limitation on our ability to export or sell our products and solutions would likely adversely affect our business, prospects, financial condition and operating results.

We may need to defend ourselves against patent, copyright or trademark infringement claims or trade secret misappropriation claims, which may be time-consuming and cause us to incur substantial costs.

Companies, organizations or individuals, including our competitors, may own or obtain patents, trademarks or other proprietary rights that would prevent or limit our ability to make, use, develop or sell our electrified powertrain solutions, which could make it more difficult for us to operate our business. We may receive inquiries from patent, copyright or trademark owners inquiring whether we infringe upon their proprietary rights. We may also be the subject of allegations that we have misappropriated their trade secrets or other proprietary rights. Companies owning patents or other intellectual property rights relating to battery packs, electric motors, fuel cells or electronic power management systems may allege infringement or misappropriation of such rights. In response to a determination that we have infringed upon or misappropriated a third party’s intellectual property rights, we may be required to do one or more of the following:

• cease development, sales or use of our products that incorporate the asserted intellectual property;

• pay substantial damages;

• obtain a license from the owner of the asserted intellectual property right, which license may not be available on reasonable terms or at all; or

• redesign one or more aspects or systems of our electrified powertrain solutions.

A successful claim of infringement or misappropriation against us could materially adversely affect our business, prospects, financial condition and operating results. Any litigation or claims, whether valid or invalid, could result in substantial costs and diversion of resources.

Our business may be adversely affected if we are unable to protect our intellectual property rights from unauthorized use by third parties.

Failure to adequately protect our intellectual property rights could result in our competitors offering similar products, potentially resulting in the loss of some of our competitive advantage and a decrease in our revenue, which would adversely affect our business, prospects, financial condition and operating results. Our success depends, at least in part, on our ability to protect our core technology and intellectual property. To accomplish this, we will

Table of Contents

rely on a combination of patents, trade secrets (including know-how), employee and third-party nondisclosure agreements, copyrights, trademarks, intellectual property licenses and other contractual rights to establish and protect our rights in our technology.

The protection of our intellectual property rights will be important to our future business opportunities. However, the measures we take to protect our intellectual property from unauthorized use by others may not be effective for various reasons, including the following:

• any patent applications we submit may not result in the issuance of patents;

• the scope of our issued patents, including our patent claims, may not be broad enough to protect our proprietary rights;

• our issued patents may be challenged or invalidated by our competitors;

• our employees or business partners may breach their confidentiality, non-disclosure and non-use obligations to us;

• third-parties may independently develop technologies that are the same or similar to our;

• the costs associated with enforcing patents, confidentiality and invention agreements or other intellectual property rights may make enforcement impracticable; and

• current and future competitors may circumvent our intellectual property.

Patent, trademark, copyright and trade secret laws vary throughout the world. Some foreign countries do not protect intellectual property rights to the same extent as do the laws of the U.S. Further, policing the unauthorized use of our intellectual property in foreign jurisdictions may be difficult. Therefore, our intellectual property rights may not be as strong or as easily enforced outside of the U.S.

Also, while we have registered trademarks in an effort to protect our investment in our brand and goodwill with customers, competitors may challenge the validity of those trademarks and other brand names in which we have invested. Such challenges can be expensive and may adversely affect our ability to maintain the goodwill gained in connection with a particular trademark.

Our intellectual property applications for registration may not issue or be registered, which may have a material adverse effect on our ability to prevent others from commercially exploiting products similar to ours.

We cannot be certain that we are the first inventor of the subject matter to which we have filed a particular patent application, or if we are the first party to file such a patent application. If another party has filed a patent application to the same subject matter as we have, we may not be entitled to the protection sought by the patent application. We also cannot be certain whether the claims included in a patent application will ultimately be allowed in the applicable issued patent. Further, the scope of protection of issued patent claims is often difficult to determine. As a result, we cannot be certain that the patent applications that we file will issue, or that our issued patents will afford protection against competitors with similar technology. In addition, our competitors may design around our issued patents, which may adversely affect our business, prospects, financial condition and operating results.

Changes in tax laws may materially adversely affect our business, prospects, financial condition and operating results.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which could adversely affect our business, prospects, financial condition and operating results. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. For example, U.S. federal tax legislation enacted in 2017, informally titled the Tax Cuts and Jobs Act (the “Tax Act”), enacted many significant changes to the U.S. tax laws. Future guidance from the IRS with respect to the Tax Act may affect us, and certain aspects of the Tax Act could be repealed or modified in future legislation. The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), has already modified certain provisions of the Tax Act. In addition, it is uncertain if and to what extent various states will conform to the Tax Act, the CARES Act or any newly enacted federal tax legislation.

Table of Contents

Our ability to use net operating loss carryforwards and other tax attributes may be limited in connection with the Business Combination or other ownership changes.

We have incurred losses during our history and do not expect to become profitable in the near future, and may never achieve profitability. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire, if at all. As of December 31, 2019, we had U.S. federal net operating loss carryforwards of approximately $43.2 million.

Under the Tax Act, as modified by the CARES Act, U.S. federal net operating loss carryforwards generated in taxable periods beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such net operating loss carryforwards in taxable years beginning after December 31, 2020, is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to the Tax Act or the CARES Act.

In addition, our net operating loss carryforwards are subject to review and possible adjustment by the IRS, and state tax authorities. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), our federal net operating loss carryforwards and other tax attributes may become subject to an annual limitation in the event of certain cumulative changes in the ownership of us. An “ownership change” pursuant to Section 382 of the Code generally occurs if one or more stockholders or groups of stockholders who own at least 5% of a company’s stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Our ability to utilize our net operating loss carryforwards and other tax attributes to offset future taxable income or tax liabilities may be limited as a result of ownership changes, including potential changes in connection with the Business Combination or other transactions. Similar rules may apply under state tax laws. We have not yet determined the amount of the cumulative change in our ownership resulting from the Business Combination or other transactions, or any resulting limitations on our ability to utilize our net operating loss carryforwards and other tax attributes. If we earn taxable income, such limitations could result in increased future income tax liability to us and our future cash flows could be adversely affected. We have recorded a full valuation allowance related to our net operating loss carryforwards and other deferred tax assets due to the uncertainty of the ultimate realization of the future benefits of those assets.

We may not be able to obtain or agree on acceptable terms and conditions for all or a significant portion of the government grants, loans and other incentives for which we may apply. As a result, our business, prospects, financial condition and operating results may be adversely affected.

We anticipate applying for federal and state grants, loans and tax incentives under government programs designed to stimulate the economy and support the production of alternative fuel and electric vehicles and related technologies. We anticipate that in the future there will be new opportunities for us to apply for grants, loans and other incentives from federal, state and foreign governments. Our ability to obtain funds or incentives from government sources is subject to the availability of funds under applicable government programs and approval of our applications to participate in such programs. The application process for these funds and other incentives will likely be highly competitive. We cannot assure you that we will be successful in obtaining any of these additional grants, loans and other incentives.

Our business and operations could be negatively affected if we become subject to any securities litigation or shareholder activism, which could cause us to incur significant expense, hinder execution of business and growth strategy and impact the price of our Common Stock and Warrants.

Shareholder activism, which could take many forms or arise in a variety of situations, has been increasing recently. Volatility in the price of our Common Stock and Warrants or other reasons may in the future cause us to become the target of securities litigation or shareholder activism. Securities litigation and shareholder activism, including potential proxy contests, could result in substantial costs and divert management’s and our Board’s attention and resources from our business. Additionally, such securities litigation and shareholder activism could give rise to perceived uncertainties as to our future, adversely affect its relationships with service providers and make it more difficult to attract and retain qualified personnel. Also, we may be required to incur significant legal fees and other expenses related to any securities litigation and activist shareholder matters. Further, the price of our Common Stock and Warrants could be subject to significant fluctuation or otherwise be adversely affected by the events, risks and uncertainties of any securities litigation and shareholder activism.

The JOBS Act permits “emerging growth companies” like us to take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies.

We qualify as an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As such, we take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies, including (a) the exemption from the auditor attestation requirements with respect to internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act, (b) the exemptions from say-on-pay, say-on-frequency and say-on-golden parachute voting requirements and (c) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. As a result, our stockholders may not have access to certain information they deem important. We will remain an emerging growth company until the earliest of (a) the last day of the fiscal year (i) following March 4, 2024, the fifth anniversary of our IPO, (ii) in which we have total annual gross revenue of at least $1.07 billion (as adjusted for inflation pursuant to SEC rules from time to time) or (iii) in which we are deemed to be a large accelerated filer, which means the market value of our Class A Common Stock that is held by non-affiliates exceeds $700 million as of the last business day of our prior second fiscal quarter, and (b) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three year period.

In addition, Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the exemption from complying with new or revised accounting standards provided in Section 7(a)(2)(B) of the Securities Act as long as we are an emerging growth company. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies, but any such election to opt out is irrevocable. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

We cannot predict if investors will find our Common Stock or Warrants less attractive because we will rely on these exemptions. If some investors find our Common Stock or Warrants less attractive as a result, there may be a less active trading market for our Common Stock or Warrants and the price of our Common Stock or Warrants may be more volatile.

Risks Related to Ownership of Our Securities

Concentration of ownership among our existing executive officers, directors and their respective affiliates may prevent new investors from influencing significant corporate decisions.

At the Closing, Thomas Healy beneficially own approximately 22.7% of the outstanding Common Stock and our executive officers, directors and their respective affiliates as a group beneficially own approximately 35.7% of the outstanding Common Stock. As a result, these stockholders are able to exercise a significant level of control over all matters requiring stockholder approval, including the election of directors, amendment of our Certificate of Incorporation and approval of significant corporate transactions. This control could have the effect of delaying or preventing a change of control of us or changes in management and will make the approval of certain transactions difficult or impossible without the support of these stockholders.

We do not expect to declare any dividends in the foreseeable future.

We do not anticipate declaring any cash dividends to holders of Common Stock in the foreseeable future. Consequently, investors may need to rely on sales of their shares after price appreciation, which may never occur, as the only way to realize any future gains on their investment.

Table of Contents

Our Certificate of Incorporation designates specific courts as the exclusive forum for certain stockholder litigation matters, which could limit the ability of our stockholders to obtain a favorable forum for disputes with us or our directors, officers or employees.

Our Certificate of Incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against current or former directors, officers or other employees for breach of fiduciary duty, other similar actions, any other action as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware and any action or proceeding concerning the validity of our Certificate of Incorporation or our Bylaws may be brought only in the Court of Chancery in the State of Delaware (or, if and only if the Court of Chancery of the State of Delaware does not have subject matter jurisdiction thereof, any state court located in the State of Delaware or, if and only if all such state courts lack subject matter jurisdiction, the federal district court for the District of Delaware), unless we consent in writing to the selection of an alternative forum. This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Our Certificate of Incorporation also provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the U.S. shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. This provision may limit our stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us and our directors, officers or other employees and may have the effect of discouraging lawsuits against our directors, officers and other employees. Furthermore, our stockholders may be subject to increased costs to bring these claims, and the exclusive forum provision could have the effect of discouraging claims or limiting investors’ ability to bring claims in a judicial forum that they find favorable.

In addition, the enforceability of similar exclusive forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that, in connection with one or more actions or proceedings described above, a court could rule that this provision in our Certificate of Incorporation is inapplicable or unenforceable. In March 2020, the Delaware Supreme Court issued a decision in Salzburg et al. v. Sciabacucchi, which found that an exclusive forum provision providing for claims under the Securities Act to be brought in federal court is facially valid under Delaware law. We intend to enforce this provision, but we do not know whether courts in other jurisdictions will agree with this decision or enforce it. If a court were to find the exclusive forum provision contained in our Certificate of Incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, prospects, financial condition and operating results.

There is no guarantee that the Warrants will be in the money at the time they become exercisable, and they may expire worthless.

The exercise price for our Warrants is $11.50 per share of Common Stock. There is no guarantee that the Warrants will be in the money following the time they become exercisable and prior to their expiration, and as such, the warrants may expire worthless.

We may amend the terms of the Warrants in a manner that may be adverse to holders with the approval by the holders of at least 50% of the then-outstanding Public Warrants. As a result, the exercise price of your Warrants could be increased, the exercise period could be shortened and the number of shares of our Common Stock purchasable upon exercise of a Warrant could be decreased, all without your approval.

Our Warrants are issued in registered form under the Warrant Agreement between the Warrant Agent and us. The Warrant Agreement provides that the terms of the Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least 50% of the then-outstanding Public Warrants to make any change that adversely affects the interests of the registered holders of Public Warrants. Accordingly, we may amend the terms of the Public Warrants in a manner adverse to a holder if holders of at least 50% of the then-outstanding Public Warrants approve of such amendment. Although our ability to amend the terms of the Public Warrants with the consent of at least 50% of the then-outstanding Public Warrants is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the Warrants, convert the Warrants into cash or stock (at a ratio different than initially provided), shorten the exercise period or decrease the number of shares of our Common Stock purchasable upon exercise of a Warrant.

We may redeem unexpired Warrants prior to their exercise at a time that is disadvantageous to warrantholders, thereby making such Warrants worthless.

We have the ability to redeem outstanding Warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per Warrant, provided that the last reported sales price of our Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 trading-day period ending on the third trading day prior to the date on which we give proper notice of such redemption and provided certain other conditions are met. If and when the Warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of the outstanding Warrants could force you (a) to exercise your Warrants and pay the exercise price therefor at a time when it may be disadvantageous for you to do so, (b) to sell your Warrants at the then-current market price when you might otherwise wish to hold your Warrants or (c) to accept the nominal redemption price which, at the time the outstanding Warrants are called for redemption, is likely to be substantially less than the market value of your Warrants. None of the Private Placement Warrants will be redeemable by us for cash so long as they are held by Tortoise Borrower or its permitted transferees.

In addition, we may redeem your Warrants after they become exercisable for a number of shares of Common Stock determined based on the redemption date and the fair market value of our Common Stock. Any such redemption may have similar consequences to a cash redemption described above. In addition, such redemption may occur at a time when the Warrants are “out-of-the-money,” in which case, you would lose any potential embedded value from a subsequent increase in the value of our Common Stock had your Warrants remained outstanding.

If securities or industry analysts do not publish or cease publishing research or reports about us, our business or our market, or if they change their recommendations regarding our Common Stock adversely, the price and trading volume of our Common Stock could decline.

The trading market for our Common Stock will be influenced by the research and reports that industry or securities analysts may publish about us, our business, our market or our competitors. If any of the analysts who may cover us change their recommendation regarding our stock adversely, or provide more favorable relative recommendations about our competitors, the price of our Common Stock would likely decline. If any analyst who may cover us were to cease their coverage or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our stock price or trading volume to decline.

A significant portion of our total outstanding shares of our Common Stock are restricted from immediate resale but may be sold into the market in the near future. This could cause the market price of our Common Stock to drop significantly, even if our business is doing well.

Sales of a substantial number of shares of our Common Stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our Common Stock. After the Closing, the initial stockholders (including Atlas Point Fund) hold approximately 4.71% of our Class A Common Stock, including the 5,825,230 shares of Class A Common Stock into which the Class B Common Stock convert. Pursuant to the terms of a letter agreement entered into at the time of the IPO, the Class B Common Stock (which were eventually converted into shares of our Common Stock at the Closing) may not be transferred until the earlier to occur of (a) one year after the Closing or (b) the date on which we complete a liquidation, merger, stock exchange or other similar transaction that results in all of our public stockholders having the right to exchange their shares of Common Stock for cash, securities or other property. Notwithstanding the foregoing, if the last sale price of our Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 trading day period commencing at least 150 days after the Closing, the shares of Common Stock into which the Class B Common Stock converted into will be released from these transfer restrictions.

Furthermore, under the Forward Purchase Agreement, the A&R Registration Rights Agreement and the Subscription Agreements, we are required to file a registration statement within 30 days after the Closing to register the resale of any shares of Common Stock issued to (a) Atlas Point Fund pursuant to the Forward Purchase Agreement, (b) the Subscribers pursuant to the Subscription Agreements and (c) certain of the stockholder parties

to the A&R Registration Rights Agreement. See the section entitled “Certain Relationships and Related Party Transactions” for a discussion of the Forward Purchase Agreement, the A&R Registration Rights Agreement and the Subscription Agreements.

We may issue additional common stock or preferred stock, including under our equity incentive plan. Any such issuances would dilute the interest of our stockholders and likely present other risks.

We may issue a substantial number of additional shares of common or preferred stock, including under our equity incentive plan. Any such issuances of additional shares of common or preferred stock:

• may significantly dilute the equity interests of our investors;

• may subordinate the rights of holders of Common Stock if preferred stock is issued with rights senior to those afforded our Common Stock;

• could cause a change in control if a substantial number of shares of our Common Stock are issued, which may affect, among other things, our ability to use our net operating loss carry forwards, if any, and could result in the resignation or removal of our present officers and directors; and

• may adversely affect prevailing market prices for our Common Stock and/or Warrants.

USE OF PROCEEDS

All of the Common Stock and Warrants offered by the Selling Securityholders pursuant to this prospectus will be sold by the Selling Securityholders for their respective accounts. We will not receive any of the proceeds from these sales.

We will receive up to an aggregate of approximately $220.6 million from the exercise of the Warrants, assuming the exercise in full of all of the Warrants for cash. We expect to use the net proceeds from the exercise of the Warrants for general corporate purposes. We will have broad discretion over the use of proceeds from the exercise of the Warrants. There is no assurance that the holders of the Warrants will elect to exercise any or all of such Warrants. To the extent that the Warrants are exercised on a “cashless basis,” the amount of cash we would receive from the exercise of the Warrants will decrease.

DETERMINATION OF OFFERING PRICE

The offering price of the shares of Common Stock underlying the Warrants offered hereby is determined by reference to the exercise price of the Warrants of $11.50 per share. The Public Warrants are listed on the NYSE under the symbol “HLYN WS.”

We cannot currently determine the price or prices at which shares of our Common Stock or Warrants may be sold by the Selling Securityholders under this prospectus.

MARKET INFORMATION FOR COMMON STOCK AND DIVIDEND POLICY

Market Information

Our Common Stock and Public Warrants are currently listed on the NYSE under the symbols “HLYN” and “HLYN WS,” respectively. Prior to the consummation of the Business Combination, our Common Stock and our Public Warrants were listed on the NYSE under the symbols “SHLL” and “SHLL WS,” respectively. As of October 1, 2020 following the completion of the Business Combination, there were 99 holders of record of our Common Stock and 3 holders of record of our Warrants. We currently do not intend to list the Private Warrants offered hereby on any stock exchange or stock market.

Dividend Policy

We have not paid any cash dividends on our Common Stock to date. We may retain future earnings, if any, for future operations, expansion and debt repayment and has no current plans to pay cash dividends for the foreseeable future. Any decision to declare and pay dividends in the future will be made at the discretion of our Board of Directors (the “Board”) and will depend on, among other things, our results of operations, financial condition, cash requirements, contractual restrictions and other factors that the Board may deem relevant. In addition, our ability to pay dividends may be limited by covenants of any existing and future outstanding indebtedness we or our subsidiaries incur. We do not anticipate declaring any cash dividends to holders of the Common Stock in the foreseeable future.

Securities Authorized for Issuance under Equity Compensation Plans

As of September 30, 2020, we did not have any securities authorized for issuance under equity compensation plans. In connection with the Business Combination, our stockholders approved our 2020 Equity Incentive Plan (the “2020 Plan”) on September 28, 2020, which became effective immediately upon the Closing.

We intend to file one or more registration statements on Form S-8 under the Securities Act to register the shares of Common Stock issued or issuable under the 2020 Plan and the assumed Legacy Hyliion options. Any such Form S-8 registration statement will become effective automatically upon filing. We expect that the initial registration statement on Form S-8 will cover shares of Common Stock underlying the 2020 Plan and the assumed Legacy Hyliion options. Once these shares are registered, they can be sold in the public market upon issuance, subject to applicable restrictions.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial statements of TortoiseCorp and Legacy Hyliion present the combination of the financial information of TortoiseCorp and Legacy Hyliion adjusted to give effect to the Business combination. The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X.

The unaudited pro forma condensed combined balance sheet as of June 30, 2020 combines the historical balance sheet of TortoiseCorp and the historical balance sheet of Legacy Hyliion on a pro forma basis as if the Business Combination and related transactions, summarized below, had been consummated on June 30, 2020. The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2019 and the six months ended June 30, 2020, combine the historical statements of operations of TortoiseCorp and Legacy Hyliion for such periods on a pro forma basis as if the business combination and related transactions, summarized below, had been consummated on January 1, 2019, the beginning of the earliest period presented:

• the merger of Merger Sub with and into Legacy Hyliion, with Legacy Hyliion surviving the merger as a wholly-owned subsidiary of TortoiseCorp;

• the issuance and sale of 30,750,000 shares of Common Stock for a purchase price of $10.00 per share and an aggregate purchase price of $307.5 million in the private placements pursuant to the Subscription Agreements and the issuance and sale of 1,750,000 Forward Purchase Units at $10.00 per unit, consisting of one share of Common Stock and one-half of one Warrant, for a total of 1,750,000 shares of Common Stock and 875,000 Warrants and an aggregate purchase price of $17.5 million pursuant to the Forward Purchase Agreement;

• the conversion of all of the Legacy Hyliion Preferred Stock and Legacy Hyliion Convertible Notes payable into our Common Stock; and

• the conversion of all outstanding Legacy Hyliion Common Stock and Legacy Hyliion Options into our Common Stock totaling 100,000,000 shares.

The historical financial statements have been adjusted in the unaudited pro forma condensed combined financial statements to give pro forma effect to events that are: (a) directly attributable to the Business Combination; (b) factually supportable; and (c) with respect to the statement of operations, expected to have a continuing impact on TortoiseCorp’s results following the completion of the Business Combination.

The unaudited pro forma condensed combined financial statements have been developed from and should be read in conjunction with:

• the accompanying notes to the unaudited pro forma condensed combined financial statements;

Pursuant to TortoiseCorp’s amended and restated certificate of incorporation, public stockholders were offered the opportunity to redeem, upon the Closing, shares of Common Stock then held by them for cash equal to their pro rata share of the aggregate amount on deposit (as of two business days prior to the Closing) in the Trust Account. The unaudited pro forma condensed combined financial statements reflect actual redemption of 3,308 shares of Common Stock at $10.15 per share.

Table of Contents

Notwithstanding the legal form of the Business Combination pursuant to the Business Combination Agreement, the Business Combination is accounted for as a reverse recapitalization in accordance with the United States generally accepted accounting principles (“GAAP”). Under this method of accounting, TortoiseCorp is treated as the acquired company and Legacy Hyliion is treated as the acquirer for financial statement reporting purposes. Legacy Hyliion has been determined to be the accounting acquirer based on evaluation of the following facts and circumstances:

• Legacy Hyliion’s existing shareholders have the greatest voting interest in the combined entity with over 59.7% voting interest;

• Legacy Hyliion-appointed directors represent four of the seven board seats for the combined company’s Board and one of the Legacy Hyliion-appointed directors was designated Chairman of the combined entity’s Board;

• Legacy Hyliion’s existing shareholders have the ability to control decisions regarding election and removal of directors and officers of the combined entity; and

• Legacy Hyliion’s senior management continued to be the senior management of the combined entity.

Assumptions and estimates underlying the unaudited pro forma adjustments set forth in the unaudited pro forma condensed combined financial statements are described in the accompanying notes. The unaudited pro forma condensed combined financial statements have been presented for illustrative purposes only and are not necessarily indicative of the operating results and financial position that would have been achieved had the Business Combination occurred on the dates indicated. Further, the unaudited pro forma condensed combined financial statements do not purport to project our future operating results or financial position following the completion of the Business Combination. The unaudited pro forma adjustments represent management’s estimates based on information available as of the date of these unaudited pro forma condensed combined financial statements and are subject to change as additional information becomes available and analyses are performed.
