(b) Principles of consolidation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and with the rules and regulations of the U.S. Securities Exchange Commission (“SEC”).

The consolidated financial statements include the financial statements of the Company and its subsidiaries. All intercompany transactions and balances among the Company and its subsidiaries have been eliminated upon consolidation. A subsidiary is an entity in which (i) the Company directly or indirectly controls more than 50% of the voting power; or (ii) the Company has the power to appoint or remove the majority of the members of the board of directors or to cast a majority of votes at the meetings of the board of directors or to govern the financial and operating activities.

Functional currency and foreign currency translation

(d) Functional currency and foreign currency translation

The Company’s reporting currency is the United States dollars (“$”). The functional currency of the Company and its subsidiary which is incorporated in BVI, Cayman islands and Hong Kong is United States dollars (“$”). The functional currencies of the other subsidiaries are their respective local currencies (“RMB”). The determination of the respective functional currency is based on the criteria set out by Accounting Standards Codification (“ASC”) 830, Foreign Currency Matters.

Revenues and expenses of its subsidiaries have been translated into U.S. dollars at average exchange rates prevailing during the period. Assets and liabilities have been translated at the rates of exchange on the balance sheet date. The resulting translation gain and loss adjustments are recorded directly as a separate component of shareholders’ equity. Transactions denominated in currencies other than the functional currency are translated into the functional currency at the exchange rates prevailing at the dates of the transactions. Exchange gains or losses arising from foreign currency transactions are included in the determination of net loss for the respective periods.

RMB is not a fully convertible currency. All foreign exchange transactions involving RMB must take place either through the People’s Bank of China (the “PBOC”) or other institutions authorized to buy and sell foreign exchange. The exchange rates adopted for the foreign exchange transactions are the rates of exchange quoted by the PBOC, which are determined largely by supply and demand. Translation of amounts from RMB into US dollars has been made at the following exchange rates for the respective periods:

Year ended December 31, 2023
Balance sheet, except for equity accounts	RMB	7.0999 to US$1.00
Income statement and cash flows	RMB	7.0811 to US$1.00

Year ended December 31, 2024
Balance sheet, except for equity accounts	RMB	7.2993 to US$1.00
Income statement and cash flows	RMB	7.1957 to US$1.00

Year ended December 31, 2025
Balance sheet, except for equity accounts	RMB	6.9931 to US$1.00
Income statement and cash flows	RMB	7.1875 to US$1.00

Restricted cash

(f) Restricted cash

Restricted cash represents for (a) frozen cash relating to the court order; (b) security deposits held in designated bank accounts for the repayment of the notes payable, and (c) security deposit for executing the sales contract with one customer.

The Company had restricted cash of $128,866 and $171,487 as at December 31, 2025 and 2024, which was recorded under the assets of discontinued operations. This frozen amount is due to the court order primarily resulted from the legal proceedings related to the contract disputes with customers (See Note20-ii) Litigation.

Accounts receivable

(h) Accounts receivable

Accounts receivable are recorded at the gross billing amount less an allowance for expected credit losses from the customers. Accounts receivable do not bear interest.

Since July 1, 2022, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), using the modified retrospective transition method. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. Upon adoption, the Company changed the impairment model to utilize a forward-looking current expected credit losses (CECL) model in place of the incurred loss methodology for financial instruments measured at amortized cost and receivables resulting from the application of ASC 606, including contract assets.

The Company maintains an allowance for credit losses in accordance with ASC Topic 326, Credit Losses (“ASC 326”) and records the allowance for credit losses as an offset to accounts receivable and contract assets, and the estimated credit losses charged to the allowance in the combined statements of operations and comprehensive income (loss). The Company assesses collectability by reviewing accounts receivable on a collective basis where similar characteristics exist, primarily based on similar business lines, services or product offerings and on an individual basis when the Company identifies specific customers with known disputes or collectability issues. In determining the amount of the allowance for credit losses, the Company considers historical collectability based on past due status, the age of the accounts receivable balances and contract assets balances, credit quality of the Company’s customers based on ongoing credit evaluations, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect the Company’s ability to collect from customer.

The Company is in the battery technology industry and generates its revenue from the battery trading business. Historical credit losses from accounts receivable and retention receivable provides the starting point for management’s assessment of the reserve for credit losses. The Company determined the CECL by estimating historical credit loss experience based on the Company’ industry demand, risk profile, or past due status and adjusted as appropriate to reflect current conditions and estimates of future economic conditions (such as GDP factor or unemployment factor).

The Company estimated the credit losses for accounts receivable based on historical credit loss experience using the roll-rate method. By utilizing the historical aging data from January 2018 to December 31, 2025, the Company estimated the credit losses on accounts receivable based on rolling loss ratio for the past three years on a semi-annual basis. In assessing relevant information, management scored its assessment of current economic conditions and future expectations, credit ratings, security deposit, and default cover age proportionally, and determined that a 100% credit loss shall be reserved for accounts receivable overdue three years.

The Company estimates credit losses for retention receivables arising from its trading business. The Company estimates the credit losses primarily based on a forward-looking assessment. This assessment incorporates macroeconomic factors and industry-specific trends, including significant economic growth rates, inflation rates, unemployment rates, and demand from the battery industry, for the period from 2020 to 2029. The balance of the allowance for credit losses recorded in continuing operations was nil as of December 31, 2025, 2024, and 2023.

Property, plant and equipment, net

(j) Property, plant and equipment, net

Property, plant and equipment (including construction in progress) are stated at cost less accumulated depreciation and impairment charges. Depreciation is calculated primarily based on the straight-line method (after taking into account their respective estimated residual values) over the estimated useful lives of the assets except the depreciation method for mold and tooling:

Category		Estimated Useful Life
Office equipment		4 – 5 years
Leasehold improvements		Shorter of lease term or estimated useful life of the assets

The cost and accumulated depreciation of property, plant and equipment sold are removed from the consolidated balance sheets and resulting gains or losses are recognized in the consolidated statements of operations and comprehensive loss. During the years ended December 31, 2025, 2024 and 2023, the Company incurred depreciation expense of $43,852, nil and nil, respectively.

Impairment of long-lived assets

(l) Impairment of long-lived assets

Property, plant, and equipment and intangible assets with definite lives are reviewed 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 estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying value of the asset exceeds the fair value of the asset.

No impairment for property, plant and equipment or intangible assets was recorded for the years ended December 31, 2025, 2024 and 2023.

Warrant Shares

(n) Warrant Shares

The Company issued warrant shares to a group of original institutional shareholders of Huizhou Yipeng and eligible to exchange the Company’s Class A ordinary shares at the par value of $0.0128 per share upon the completion of the approvals from and filings and registrations with competent branches of Chinese State Administration of Foreign Exchange (“SAFE”) office, National Development and Reform Commission (“NDRC”) and Ministry of Commerce (“ MOFCOM”) as well as other competent PRC governmental authorities with jurisdiction of the outbound direct investment by PRC entities (the “ODI Approvals”) (“Warrant Shares “).

The accounting treatment of warrant shares is determined pursuant to the guidance provided by ASC 815, Derivatives and Hedging (“ASC 815”), as applicable. The freestanding equity-linked instrument that becomes issuable, exercisable, or settleable only upon the occurrence or nonoccurrence of a specified event is considered issued for accounting purpose and evaluated under ASC 815-40. After evaluation that the Warrant Shares are indexed to and settled in the Company’s own stock, management classified the issued Warrant Shares as equity.

In November 2023, the Company issued 82,368 Warrant Shares to certain holders, and the holders of Warrant Shares exercised all of their warrants converted into 28,775 Class A ordinary shares on October 29, 2024 upon the completion of the ODI Approvals on September 11, 2024.

Product warranty

(p) Product warranty

The Company provides a standard warranty on its products sold, which entails repair or replacement of non-conforming items, in conjunction with the sales of products.

The Company’s product warranty generally ranges from one1 to five years (or a minimum of 6,000 charge-discharge cycles). The Company establishes a reserve for the estimated cost of the product warranty at the time revenue is recognized. 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, including actual claims incurred to date and an estimate of the nature, frequency and costs of future claims for each customer.

The Company review and adjust the estimates to ensure that accruals are adequate to meet expected future warranty obligations. Initial warranty data is limited early in the launch of a new product and accordingly, future adjustments to the warranty accrual may be material.

The portion of the warranty that is expected to incur within the next 12 months is recorded in current liabilities, while the remaining balance is recorded in non-current liabilities on the consolidated balance sheets. Warranty expense is recorded as a component of selling expenses.

The Company considers the standard warranty is not providing incremental service to customers rather than assurance to the quality of the battery and energy storage system products, and therefore is not a separate performance obligation and should be accounted for in accordance with ASC 460, Guarantees.

Research and development expenses

(r) Research and development expenses

All costs associated with research and development (“R&D”) is expensed as incurred.

Employee benefits

(t) Employee benefits

Full-time employees of the Company in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, work-related injury benefits, maternity insurance, medical care, employee housing fund and other welfare benefits are provided to the employees. Chinese labor regulations require that the PRC subsidiaries of the Company make contributions to the government for these benefits based on certain percentages of the employees’ salaries, up to a maximum amount specified by the local government. The PRC government is responsible for the medical benefits and the pension liability to be paid to these employees and the Company’s obligations are limited to the amounts contributed and no legal obligation beyond the contributions made. For the years ended December 31, 2025, 2024 and 2023, employee benefits expenses were $10,769, $9,060 and nil respectively.

Income taxes

(v) Income taxes

Current income taxes are recorded in accordance with the regulations of the relevant tax jurisdiction. The Company accounts for income taxes under the asset and liability method in accordance with ASC 740, Income Tax. Under this method, deferred tax assets and liabilities are recognized for the tax consequences attributable to differences betwee2n carrying amounts of existing assets and liabilities in the consolidated financial statements and their respective tax basis, and operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of operations and comprehensive loss in the period of change. Valuation allowances are established when necessary to reduce the amount of deferred tax assets if it is considered more likely than not that amount of the deferred tax assets will not be realized.

Uncertain tax positions

An uncertain tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Penalties and interest incurred related to underpayment of income tax are classified as income tax expense in the period incurred. Interest and penalties related to uncertain tax positions, if any, are recorded under accrued expenses and other current liabilities on its consolidated balance sheets and under other expenses in its consolidated statements of comprehensive loss. The Company did not recognize any significant interest and penalties associated with uncertain tax positions for the years ended December 31, 2025, 2024 and 2023. As of December 31, 2025 and 2024, the Company did not have any significant unrecognized uncertain tax positions.

Comprehensive income (loss)

(x) Comprehensive income (loss)

The Company applies ASC 220, Comprehensive Income, with respect to reporting and presentation of comprehensive loss and its components in a full set of financial statements. Comprehensive loss is defined to include all changes in equity of the Company during a period arising from transactions and other events and circumstances except those resulting from investments by shareholders and distributions to shareholders. For the periods presented, the Company’s comprehensive loss includes net loss and other comprehensive loss, which primarily consists of the foreign currency translation adjustments.

Net loss per share

(z) Net loss per share

The Company complies with accounting and disclosure requirements ASC Topic 260, “Earnings Per Share.” Earnings (losses) per ordinary share is computed by dividing net income by the weighted average number of ordinary shares issued and outstanding for the periods except that it does not include ordinary shares subject to forfeiture or cancellation. Diluted net income per share is computed using the weighted average number of ordinary shares and, if dilutive, potential ordinary shares outstanding during the period. Potentially dilutive securities have been excluded from the computation of diluted net income per share if their inclusion is anti-dilutive. Potential ordinary shares consist of the incremental ordinary shares issuable upon the exercise of stock options, warrants, and unvested restricted shares. The dilutive effect of outstanding stock options, warrants, and restricted shares is reflected in diluted earnings per share by application of the treasury stock method and the if-converted method, respectively. For the years ended December 31, 2025, 2024 and 2023, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the income of the Company. As a result, diluted earnings per ordinary share is the same as basic earnings per ordinary share for the periods presented.

In according with ASC 260-10-45, the 235 Indemnity Escrow Shares and 7,032 Earnout Escrow Shares are considered contingently returnable shares and therefore are excluded from the computation of basic and diluted earnings per share for the years ended December 31, 2025, 2024 and 2023 (on a retroactively adjusted basis).
