The Company recently acquired new fuel agnostic capable generator technology with which it plans to develop and commercialize the Hypertruck KARNO. Note 2. Summary of Significant Accounting Policies Basis of Presentation These condensed consolidated statements include the accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”), which permit reduced disclosure for interim periods. All intercompany transactions and balances have been eliminated upon consolidation. The condensed consolidated balance sheet at December 31, 2021 was derived from audited financial statements for the fiscal year then ended, but does not include all necessary disclosures required with respect to annual financial statements. In the opinion of the Company, these condensed consolidated financial statements include all recurring adjustments and normal accruals necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the dates and periods presented. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s 2021 Annual Report. Results for interim periods are not necessarily indicative of the results to be expected for a full fiscal year or for any future period. These condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and settlement of liabilities in the normal course of business. The Company is an early-stage growth company and has generated negative cash flows from operating activities since inception. At September 30, 2022, the Company had total equity of $ 451.2 million, inclusive of cash and cash equivalents of $ 154.2 million and investments of $ 301.3 million. Based on this, the Company has sufficient funds to continue to execute its business strategy for the next twelve months. Use of Estimates and Uncertainty of the Coronavirus Pandemic The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the balance sheet date, as well as reported amounts of expenses during the reporting period. The Company’s most significant estimates and judgments involve revenue recognition, inventory, warranties, acquisitions, income taxes and valuation of share-based compensation. The Company bases its estimates on historical experience and on various other assumptions believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates, and such differences could be material to the Company’s financial statements. On January 30, 2020, the World Health Organization declared the coronavirus outbreak a “Public Health Emergency of International Concern” and on March 11, 2020, declared the coronavirus outbreak a pandemic. In mid-March 2020, U.S. State Governors, local officials and leaders outside of the U.S. began ordering various “shelter-in-place” orders, which have had various impacts on the U.S. and global economies. The lingering impacts of the coronavirus pandemic primarily include ongoing shortages in the transportation industry supply chain. Concentration of Supplier Risk The Company is dependent on certain suppliers, the majority of which are single source suppliers, and the inability of these suppliers to deliver necessary components of the Company’s products in a timely manner at prices, quality levels and volumes 5 that are acceptable, or the Company’s inability to efficiently manage these components from these suppliers, could have a material adverse effect on the Company’s business, prospects, financial condition and operating results. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity date of 90 days or less at the time of purchase to be cash and cash equivalents only if in checking, savings or money market accounts. Cash and cash equivalents include cash held in banks and money market accounts and are carried at cost, which approximates fair value. The Company maintains cash in excess of federally insured limits at financial institutions which it believes are of high credit quality and has not incurred any losses related to these balances to date. The Company believes its credit risk, with respect to these financial institutions to be minimal. Restricted Cash The Company has provided its corporate headquarters lessor with a letter of credit for $ 0.7 million to secure the performance of the Company's lease obligations, backed by a restricted cash deposit to pay any draws on the letter of credit by the lessor. Total cash and cash equivalents and restricted cash presented in the condensed consolidated statements of cash flows is summarized as follows: September 30, 2022 December 31, 2021 September 30, 2021 December 31, 2020 Cash and cash equivalents $ 154,161 $ 258,445 $ 289,486 $ 389,705 Restricted cash included in other non-current assets 665 665 698 — $ 154,826 $ 259,110 $ 290,184 $ 389,705 Accounts Receivable Accounts receivable are stated at gross invoice amount, net of an allowance for doubtful accounts. The allowance for doubtful accounts is maintained at a level considered adequate to provide for potential account losses on the balance based on the Company’s evaluation of the anticipated impact of current economic conditions, changes in the character and size of the balance, past and expected future loss experience and other pertinent factors. At September 30, 2022 and December 31, 2021, accounts receivable included amounts receivable from customers of $ 0.6 million and $ 45.0 thousand, respectively. At September 30, 2022 and December 31, 2021, there was no allowance for doubtful accounts required based on the Company's evaluation. Investments The Company’s investments consist of corporate bonds, U.S. treasury and agency securities, state and local municipal bonds and commercial paper, all of which are classified as held-to-maturity, with a maturity date of 36 -months or less at the time of purchase. The Company determines the appropriate classification of investments at the time of purchase and re-evaluates such designation as of each balance sheet date. Investments are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost, adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization, along with interest, is included in interest income. The Company uses the specific identification method to determine the cost basis of securities sold. Investments are impaired when a decline in fair value is judged to be other-than-temporary. The Company evaluates investments for impairment by considering the length of time and extent to which market value has been less than cost or amortized cost, the financial condition and near-term prospects of the issuer as well as specific events or circumstances that may influence the operations of the issuer and the Company’s intent to sell the security or the likelihood that it will be required to sell the security before recovery of the entire amortized cost. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded to other income and a new cost basis in the investment is established. Fair Value Measurements ASC 820, Fair Value Measurements , clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based upon assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level I : Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Company can access at the measurement date; 6 Level II : Significant other observable inputs other than level I prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data; and Level III : Significant unobservable inputs that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. An asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used maximize the use of observable inputs and minimize the use of unobservable inputs. The Company believes its valuation methods are appropriate and consistent with other market participants, however the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The Company’s financial instruments consist of cash and cash equivalents and restricted cash, accounts receivable, investments, accounts payable and accrued expenses for which the carrying value approximates fair value, exclusive of any interim unrealized gains or losses, because of the short-term nature of the instruments. The fair values of investments are based on quoted prices for identical or similar instruments in markets that are not active. As a result, investments are classified within Level II of the fair value hierarchy. Revenue The Company follows five steps to recognize revenue from contracts with customers under ASC 606, Revenue from Contracts with Customers , which are: Step 1 : Identify the contract(s) with a customer; Step 2 : Identify the performance obligations in the contract; Step 3 : Determine the transaction price; Step 4 : Allocate the transaction price to the performance obligations in the contract; and Step 5 : Recognize revenue when (or as) a performance obligation is satisfied. Revenue is comprised of sales of Hybrid systems for Class 8 semi-trucks, Class 8 semi-trucks outfitted with Hybrid systems and specific other features and services that meet the definition of a performance obligation, including internet connectivity and data processing. We provide installation services for the Hybrid system onto the customers’ vehicle. The Company’s products are marketed and sold to end-user fleet customers in North America. When our contracts with customers contain multiple performance obligations and where material, the contract transaction price is allocated on a relative standalone selling price basis to each performance obligation. There is no meaningful basis on which to disaggregate revenue in the current period. We recognize revenue on Hybrid system sales and Class 8 semi-trucks outfitted with Hybrid systems upon delivery and acceptance of the vehicle to the customer, which is when control transfers. Contracts are reviewed for significant financing components and payments are typically received within 30 days of delivery. The sale of a Hybrid system to an end-use fleet customer consists of a completed modification to the customer vehicle and the installation services involve significant integration of the Hybrid system with the customer’s vehicle. Installation services are not distinct within the context of the contract and together with the sale of the Hybrid system represent a single performance obligation. We do not offer any sales returns. Amounts billed to customers related to shipping and handling are classified as revenue, and we have elected to recognize the cost for freight and shipping when control has transferred to the customer as a cost of revenue. Our policy is to exclude taxes collected from customers from the transaction price of contracts. In the fourth quarter of fiscal 2021, we began taking deposits to secure future Hypertruck ERX production slots. When a Class 8 semi-truck outfitted with a Hybrid system is resold to a customer, judgment is required to determine if we are the principal or agent in the arrangement. We consider factors such as, but not limited to, which entity has the primary responsibility for fulfilling the promise to provide the specified good or service, which entity has inventory risk before the specified good or service has been transferred to a customer and which entity has discretion in establishing the price for the specified good or service. We have determined that we are the principal in transactions involving the resale of Class 8 semi-trucks outfitted with the Hybrid system. 7 The disaggregation of our revenue sources for the three and nine months ended September 30, 2022 and 2021 is summarized as follows: Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Hybrid systems and other $ 243 $ — $ 755 $ — Class 8 semi-truck prepared for Hybrid system upfit 256 — 256 — Total product sales and other $ 499 $ — $ 1,011 $ — Warranties We provide limited assurance-type warranties under our contracts and do not offer extended warranties or maintenance contracts. The warranty period typically extends for the lesser of two years or 200,000 miles following transfer of control and solely relate to correction of product defects during the warranty period. We recognize the cost of the warranty upon transfer of control based on estimated and historical claims rates and fulfillment costs, which are variable. Should product failure rates and fulfillment costs differ from these estimates, material revisions to the estimated warranty liability would be required. Warranty expense is recorded as a component of cost of revenue. Note 3. Acquisition In September 2022, we acquired certain assets (the "Acquired Assets") of General Electric Company's GE Additive business (the "Acquisition"). The Acquired Assets include new hydrogen and fuel agnostic capable generator technology (“KARNO”). The Acquisition did not meet the definition of a business combination and was accounted for as an asset acquisition. No goodwill was recognized and payments allocated to in-process research and development ("IPR&D") were recorded in research and development expense as there was no alternative future use. Total consideration for the Acquisition was $ 32.3 million comprised of $ 15.0 million in cash, 5,500,000 shares of common stock valued at $ 16.1 million on the closing date and $ 1.2 million in direct transaction costs. $ 3.6 million was recorded as property and equipment with expected useful lives of primarily five years and $ 28.8 million was recorded as research and development expense. All assets were valued using level 3 inputs, with property and equipment valued using a market approach and IPR&D valued using an income approach based on Company management’s projections. The cash component of the consideration was recorded in the statement of cash flows and allocated between purchase of property and equipment and purchase of IPR&D under investing activities. 8 Note 4.
