The accompanying consolidated financial statements of the Group have been prepared on the going concern basis, which contemplates the continuity of normal business activities and the realization of assets and the discharge of liabilities in the normal course of business.

For the years ended December 31, 2023, 2022 and 2021, the Group generated revenues of $306,617, $204,495 and $151,976, gross profit /(loss) of $57,227, $9,073 and $(42,743), and incurred net losses of $106,412, $158,200 and $206,483, respectively.

Despite the above, the Group has incurred significant losses and negative cash flows from operations in the last three years. For the years ended December 31, 2023, 2022 and 2021, the Group incurred net losses of $106,412, $158,200 and $206,483, respectively, and generated negative cash flows from operating activities amounting to $75,303, $53,928 and $45,039, respectively. As of December 31, 2023, the Group had working capital of $22,196, shareholders’ equity of $564,190, including an accumulated deficit of $897,501, and cash and cash equivalents balance of $44,541. As of December 31, 2023, the Group also had outstanding borrowings of $79,153, of which the amount to be paid in the next 12 months is $35,392, and other current liabilities of $368,018, including accounts payable, notes payable, accrued expenses and other current liabilities. Purchase commitments for non-cancelable contractual obligations primarily related to purchases of inventory were $52,588 as of December 31, 2023.

In addition, the Group launched its new 53.5Ah cell technology in 2021, which necessitated significant investment in capacity expansions in both Huzhou, China and Tennessee, United States. The 2GWh cell, module and tray expansion in Huzhou was completed in the third quarter of 2023 and is now generating revenue. The Tennessee 2GWh expansion, which utilizes the same production equipment as the one used in the Huzhou expansion, was originally scheduled to be completed in the fourth quarter of 2023. Management now estimates this project will not be in operation until it raises sufficient funding to meet the remaining capital expenditure needs. Due to the Tennessee capacity expansion, as of and for the year ended December 31, 2023, the Group had long-lived assets located in the United States accounting for 49% of the Groups' long-lived assets while revenues from the United States customers only represented 1% of the Group's revenues. Refer to Note 25 for details.

The Group expects that an additional $150,000 to $170,000 of funding will be needed to complete the Tennessee capacity expansion, including payment for certain accounts payable owed to suppliers in relation to assets and services provided for this expansion. As of December 31, 2023, the Group has made total capital commitments for construction and purchase of property, plant and equipment amounting to $64,686, $57,577 of which is payable within one year, and most of which relates to production equipment to be used in the Tennessee facility. These capital commitments have been included in the estimated $150,000 to $170,000 required to complete the Tennessee capacity expansion.

The Group has outstanding payables in relation to assets and services provided for the Tennessee capacity expansion amounting to $56,985 that are currently due to its suppliers as of December 31, 2023 and the Group has received notice of non-payment from certain of these suppliers with a total amount of $5,548. Further, as of today, there are several suppliers which have filed liens mostly with the county in which the Tennessee project is situated, with a total amount of $31,907 received by the Group. One supplier has also filed a litigation alleging that the Group failed to pay for the construction work performed on the Tennessee project. Refer to Note 28 for details.

In light of the Group’s projected capital expenditures required to complete its Tennessee capacity expansion and its operating requirements under its current business plan, the Group is projecting that its existing cash and cash equivalents will not be sufficient to fund its operations and capital expenditure needs through the next twelve months from the date of issuance of its consolidated financial statements. These conditions and events raise substantial doubt about the Group’s ability to continue as a going concern and the Group's ability to continue as a going concern is dependent on its ability to raise additional capital. As of the date of issuance of the financial statements, the Group is pursuing a Proposed Term Loan, further described below.

Proposed Term Loan – To meet its funding needs, management is seeking to secure a loan intended to support the Tennessee capacity expansion for which the amount may be disbursed in multiple advances. As of the date of issuance of the financial statements, the Group is in the process of negotiating a credit agreement of $150,000 with a third party lender (the “Proposed Term Loan”) with a maturity term of four years from the closing date. Under the Proposed Term Loan, advances are subject to the satisfaction or waiver of a number of conditions, including but not limited to the delivery of certain customary certifications, as well as opinions from its legal counsel as to certain matters related to the applicability and availability of certain tax credits and enforceability, the assignment to a US subsidiary of certain assets related to the Tennessee project and payment to the lender of certain upfront fees and expenses. Additionally, prior to finalizing the Proposed Term Loan, certain other arrangements have to be negotiated, which include but are not limited to, entering into a $30,000 working capital loan simultaneously with the Proposed Term Loan. The Group is in process of negotiating those arrangements.

Besides the Proposed Term Loan, the Group is currently evaluating several different other funding initiatives. Such initiatives in consideration include the issuance of debt or equity instruments and/or the sale or disposal of certain US real estate assets that are not integral to its cell manufacturing or assembly operations. As of the date of issuance of those financial statements, the Group is currently prioritizing closing the Proposed Term Loan whilst any other funding initiatives remain under review.

These plans are not final and are subject to market and other conditions not within the Group’s control. As such, there can be no assurance that the Group will be successful in obtaining sufficient funding. Should sufficient funding not be secured through the plans, or should there be a delay in the timing of securing funds through these funding initiatives, this would have adverse implications for the Group and its shareholders. In these scenarios, the Group will need to seek other options, including delaying or reducing operating and capital expenditure and the possibility of an alternative transaction or fundraising.

Accordingly, management has concluded that these plans do not alleviate the substantial doubt about the Group’s ability to continue as a going concern within one year after the date the consolidated financial statements are issued. Based on the factors above, a material uncertainty exists which may cast significant doubt as to whether the Group will continue as a going concern and therefore whether it will realize its assets and discharge its liabilities in the normal course of business and at the amounts stated in the financial statements. The accompanying consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or to the amounts and classification of liabilities that might be necessary should the Group not continue as a going concern.

For the Company’s consolidated subsidiaries, noncontrolling interests are recognized to reflect the portion of their equity that is not attributable, directly or indirectly, to the Company as the controlling shareholder. Noncontrolling interests are classified as a separate line item in the equity section of the Company’s consolidated balance sheets and have been separately disclosed in the Company’s consolidated statements of operations and comprehensive loss to distinguish the interests from that of the Company.

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue, costs and expenses in the consolidated financial statements and accompanying notes, and disclosure of contingent liabilities at the date of the consolidated financial statements. Actual results could differ from these estimates. Significant accounting estimates reflected in the Group’s financial statements include allowance for credit losses, provision for obsolete inventories, impairment of long-lived assets, valuation allowance for deferred tax assets, product warranties, fair value measurement of Bridge Notes, fair value measurement of warrant liability and share based compensation.

Pursuant to the JOBS Act, an emerging growth company may adopt new or revised accounting standards that may be issued by FASB or the SEC either (i) within the same periods as those otherwise applicable to non-emerging growth companies or (ii) within the same time periods as private companies. The Company intends to take advantage of the exemption for complying with new or revised accounting standards within the same time periods as private companies. Accordingly, the information contained herein may be different than the information provided by other public companies.

The Company also intends to take advantage of some of the reduced regulatory and reporting requirements of emerging growth companies pursuant to the JOBS Act so long as the Company qualifies as an emerging growth company, including, but not limited to, an exemption from the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation, and exemptions from the requirements of holding non-binding advisory votes on executive compensation and golden parachute payments.

Restricted cash represents deposits made to banks to secure bank acceptance notes (or Notes Payable), letters of credit issued by the Group, and restricted use bank borrowings (see Note 12). It is common in the PRC that the banks require the Group to pledge notes receivable or make a deposit as collateral. The deposits and the matured bank acceptance notes from its customers are recorded as restricted cash in the consolidated balance sheets.

Accounts receivable represents those receivables derived in the ordinary course of business, net of allowance for credit losses. Beginning on January 1, 2022, the Group evaluates its accounts receivable for expected credit losses on a regular basis. The Group maintains an estimated allowance for credit losses to reduce its accounts receivable to the amount that it believes will be collected. The Group uses the creditworthiness of customers, aging of the receivables, past transaction history with customers and their current condition, changes in customer payment terms, specific facts and circumstances, and the overall economic climate in the industries the Group serves to monitor the Group's receivables within the scope of expected credit losses model and use these as a basis to develop the Group's expected loss estimates.

The Group accepts bank acceptance notes (“notes”) from customers in the PRC in the normal course of business. The Group may present these notes with banks in the PRC for cash payment or endorse these notes to its suppliers to settle its accounts payable. The Group derecognised the endorsed notes upon transferring them to its suppliers as the Group loses effective control over these notes. Notes receivable and payable are typically non-interest bearing and have maturities of one year or less.

The Group’s short-term held-to-maturity investments are classified based on their contractual maturity dates which are less than one year and are recorded at their amortized costs. The Company recognized $—, $70 and $438 interest income from the short-term investments for the years ended December 31, 2021, 2022 and 2023, respectively.

The Group reviews its held-to-maturity investments for other-than-temporary impairment (“OTTI”) based on the specific identification method. The Group considers available quantitative and qualitative evidence in evaluating the potential impairment of its short-term investments. If the cost of an investment exceeds the investment’s fair value, the Group considers, among other factors, general market conditions, expected future performance of the instruments, the duration and the extent to which the fair value of the investment is less than the cost, and the Group’s intent and ability to hold the investments. OTTI is recognized as a loss in the consolidated statements of operations.

Inventories of the Group consist of raw materials, work in process and finished goods. Inventories are stated at the lower of cost or net realizable value. Inventory costs include expenses that are directly or indirectly incurred in the acquisition and production process, including shipping and handling costs charged by suppliers. The cost of materials and supplies used in production, direct labor costs and allocated overhead costs are all included in the inventory costs. The allocated overhead cost includes depreciation, insurance, employee benefits, and indirect labor. Cost is determined using the weighted average method. Inventories are written down to net realizable value taking into consideration of estimates of future demand, technology developments, market conditions and reasonably predicative costs of completion or disposal.

Construction in progress represents manufacturing facilities and equipment under construction, and is stated at cost. The capitalization of these costs ceases when construction in progress is transferred to property, plant and equipment and substantially ready for its intended use. No depreciation is recorded for construction in progress. Repair and maintenance costs are charged to expenses as incurred.

Land use rights are recorded at cost less accumulated amortization. Amortization is provided on a straight-line basis over the estimated useful lives, which are generally 50 years and represent the shorter of the estimated usage periods or the terms of the land use rights agreements.

The Company reviews long-lived assets with finite lives, including identifiable intangible assets with determinable useful lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future net undiscounted cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Fair value is estimated based on various valuation techniques, including the discounted value of estimated future cash flows. The evaluation of asset impairment requires the Group to make assumptions about future cash flows over the life of the asset being evaluated. These assumptions require significant judgment and actual results may differ from assumed and estimated amounts. Refer to Note 7 for details.

Financial instruments include cash and cash equivalents, restricted cash, short-term investments, accounts receivable, notes receivable, other receivable, amounts due from/to related parties, accounts payable, short-term bank borrowings, notes payable, bonds payable, Bridge Notes and warrant liability. The Group carries its cash and cash equivalents, restricted cash, Bridge Notes and warrant liability at fair value. The carrying values of other current financial instruments approximate their fair values reported in the consolidated balance sheets due to their short-term maturity.

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

Authoritative literature provides a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset or liability categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement as follows:

Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

The Group’s revenue consists primarily of sales of lithium-ion batteries. The obligation of the Group is providing the battery products. Revenue is recognized at the point of time when control of the promised goods or services is transferred to the customer, in an amount that reflects the consideration the Group expects to be entitled to in exchange for the goods or services.

Contract balances include accounts receivable and advances from customers. Accounts receivable represent cash not received from customers and are recorded when the rights to consideration is unconditional. The allowance for credit losses reflects the best estimate of probable losses inherent to the accounts receivable balance. Contract liabilities, recorded in advance from customers in the consolidated balance sheet, represent payment received in advance. During the years ended December 31, 2021, 2022 and 2023, the Group recognized $1,455, $1,151 and $2,492 of revenue previously included in advance from customers as of January 1, 2021, January 1, 2022 and January 1, 2023, respectively, which consist of payments received in advance related to its sales of lithium-ion batteries.

Cost of revenues primarily consists of the cost of the products ultimately sold to customers, shipping and handling costs charged to the Group in the sales, product warranty expense, provision for obsolete inventories and other related cost that are directly attributable to the production of products.

The Group provides product warranty, which entails repair or replacement of non-conforming items, in conjunction with the sales of products. The warranty liability recorded at each balance sheet date reflects management’s best estimates of its product warranty based on historical information and other currently available evidence.

The Group’s product warranty generally ranges from one to eight years. The Group establishes a reserve for the estimated cost of the product warranty at the time revenue is recognized. The portion of the warranty that is expected to incur within the next 12 months is recorded in accrued expenses and other current liabilities, while the remaining balance is recorded in other non-current liabilities on the consolidated balance sheets. Product warranty is recorded as a cost of revenues.

Research and development expenses primarily consist of salaries and benefits for research and development personnel, raw materials, office rental expense, general expenses and depreciation expenses associated with research and development activities.

Government subsidies related to the investment in production facilities is initially recorded as other current or other non-current liabilities and is amortized on a straight-line basis to offset the cost of revenues over the life of the relevant production assets or amortized on an effective interest method over the term of the loan.

The Group amortized the deferred subsidy at $269, $538 and $390 during the years ended December 31, 2021, 2022 and 2023, respectively. As of December 31, 2022 and 2023, the carrying amount of the current portion of the deferred subsidy income was $542 and $531, and the non-current portion was $3,066 and $3,382, respectively.

Current income taxes are provided for in accordance with the laws of the relevant tax authorities. Deferred income taxes are recognized when temporary differences exist between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements. Net operating loss carry forwards and credits are applied using enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more-likely-than-not that a portion of or all of the deferred tax assets will not be realized.

The Group accounts for uncertain tax positions by reporting a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. Tax benefits are recognized from uncertain tax positions when the Group believes that it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The Group recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

Share-based payment transactions with employees are measured based on the grant date fair value of the equity instrument and recognized as compensation expense on a straight-line basis over the requisite service period, with a corresponding impact reflected in additional paid-in capital.

For share-based awards granted with performance condition, the compensation cost is recognized when it is probable that the performance condition will be achieved. The Company reassesses the probability of achieving the performance condition at the end of each reporting date and records a cumulative catch-up adjustment for any changes to its assessment. For performance-based awards with a market condition, such as awards based on total shareholder return (“TSR”), compensation expense is recognized on a straight-line basis over the estimated service period of the award, regardless of whether the market condition is satisfied. Forfeitures are recognized as they occur.

On January 1, 2022, the Company adopted ASU No. 2016-02, Leases (Topic 842) (“ASC 842”), using the modified retrospective transition method resulting in the recording of operating lease right-of-use (ROU) assets of $18,826 and operating lease liabilities of $18,776 upon adoption. Prior period amounts have not been adjusted and continue to be reported in accordance with the previous accounting guidance. The adoption of the new guidance did not have a material effect on the consolidated statements of operations. As of December 31, 2023, the Company recorded operating lease right-of-use (ROU) assets of $19,507 and operating lease liabilities of $19,500, including current portion in the amount of $2,413, which was recorded under accrued expenses and other current liabilities on the balance sheet.

The Company determines if an arrangement is a lease or contains a lease at lease inception. Operating leases are required to be recorded in the statement of financial position as right-of-use assets and lease liabilities, initially measured at the present value of the lease payments. The Company has elected the package of practical expedients, which allows the Company not to reassess (1) whether any expired or existing contracts as of the adoption date are or contain a lease, (2) lease classification for any expired or existing leases as of the adoption date and (3) initial direct costs for any expired or existing leases as of the adoption date. The Company also elected the practical expedient not to separate lease and non-lease components of contracts. Lastly, for lease assets other than real estate, such as printing machines and electronic appliances, the Company elected the short-term lease exemption as their lease terms are 12 months or less.

As the rate implicit in the lease is not readily determinable, the Company estimates its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The incremental borrowing rate is estimated in a portfolio approach to approximate the interest rate on a collateralized basis with similar terms and payments in a similar economic environment. Lease expense is recorded on a straight-line basis over the lease term.

The Company accounts for warrants in accordance with the guidance contained in ASC 815-40 under which the warrants do not meet the criteria for equity treatment and must be recorded as liabilities. As the Private Warrants (as defined below Note 15) meet the definition of a derivative as contemplated in ASC 815, the Company classifies the Private Warrants as liabilities. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the statements of operations. The Private Warrants are valued using a Monte Carlo simulation model on the basis of the quoted market price of the Company’s publicly-traded warrants.

Basic loss per share is computed by dividing net loss attributable to common stock, considering the accretions to redemption value of any preferred shares, by the weighted average number of common stock outstanding during the year using the two-class method. Under the two-class method, any net loss is allocated between Common Stock and other participating securities based on their participating rights. Net loss is not allocated to participating securities when the participating securities do not have a contractual obligation to share losses.

The Company’s preferred shares that existed before its Merger, were participating securities as they participated in undistributed earnings on an as-if-converted basis. The preferred shares had no contractual obligation to fund or otherwise absorb the Company’s losses. Accordingly, any undistributed net loss was allocated on a pro rata basis to the common stock and preferred shares; whereas any undistributed net loss is allocated to ordinary shares only. All preferred shares that existed prior to the Merger were converted into common stock pursuant to the Merger and as of December 31, 2023, the Company does not have any preferred shares in issue.

Diluted loss per share is calculated by dividing net loss attributable to Common Stock, as adjusted for the accretion and allocation of net loss related to preferred shares, if any, by the weighted average number of Common Stock and dilutive Common equivalent stock outstanding during the period. Common equivalent stock consist of shares issuable upon the conversion of any preferred shares and convertible bonds using the if-converted method, and Common Stock issuable upon the vesting of non-vested shares or exercise of outstanding share options (using the treasury stock method). Common equivalent stock are calculated based on the most advantageous conversion rate or exercise price from the standpoint of the security holder. Common equivalent stock are not included in the denominator of the diluted earnings per share calculation when inclusion of such shares would be anti-dilutive.

The functional currency of the Company and all subsidiaries located in the U.S. is the United States dollar (“U.S. dollar”). For the Company’s subsidiaries located in the PRC, the functional currency is the Chinese Renminbi (“RMB”); the Company’s UK subsidiary, MP UK, the functional currency is the Great British Pound (“Pound”); the Company’s Germany subsidiary, MV GmbH, the functional currency is the Euro, and the Company’s Singapore subsidiary, MV Singapore, the functional currency is the Singapore Dollar (“SGD”).

In preparing the consolidated financial statements of each individual group subsidiary, transactions in currencies other than the subsidiary’s functional currency (foreign currencies) are converted into the functional currency at the rates of exchange prevailing on the dates of the transactions. At the end of each reporting period, monetary items denominated in foreign currencies are translated at the rates prevailing at that date. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated.

For the purposes of presenting the consolidated financial statements, the assets and liabilities of the Group’s foreign operations are translated into the reporting currency of the Group (i.e. US$) at the prevailing exchange rate at the end of the reporting period, and their income and expenses are translated at the average exchange rates for the year. Translation adjustments are reported as cumulative translation adjustments and are shown as a component of other comprehensive loss.

RMB is not a freely convertible currency. The State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into other currencies. The value of the RMB is subject to changes in central government policies and to international economic and political developments affecting supply and demand in the China Foreign Exchange Trading System market. Cash and cash equivalents and restricted cash of the Group included aggregate amounts of $98,021 and $62,829 as of December 31, 2022 and 2023, respectively, which were denominated in RMB.

Financial instruments that potentially expose the Group to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, accounts receivable, notes receivable and short-term investments. The Group places its cash and cash equivalents with financial institutions with high credit ratings and quality. The Group conducts credit evaluations of customers and generally does not require collateral or other security from its customers.

The Group relies on third parties for the supply of raw materials. In instances where these parties fail to perform their obligations, the Group may find alternative suppliers in the open market. For the years ended December 31, 2021, 2022 and 2023, 12%, 18% and 15% of our raw materials were purchased through company E and F, respectively, although numerous alternate sources of supply are readily available on comparable terms for the raw materials supplied by company E and F.

In November 2023, the FASB issued ASU 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" ("ASU 2023-07"). ASU 2023-07 intends to improve reportable segment disclosure requirements, enhance interim disclosure requirements and provide new segment disclosure requirements for entities with a single reportable segment. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods with fiscal years beginning after December 15, 2024. ASU 2023-07 is to be adopted retrospectively to all prior periods presented. The Company is currently assessing the impact this guidance will have on the consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09 "Improvements to Income Tax Disclosures" ("ASU 2023-09"). ASU 2023-09 intends to improve the transparency of income tax disclosures. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024 and is to be adopted on a prospective basis with the option to apply retrospectively. The Company is currently assessing the impact of this guidance, however, the Company do not expect a material impact to the consolidated financial statements.
