Summary of Significant Accounting Policies</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Basis of preparation</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The unaudited consolidated financial statements of the Company have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for the complete consolidated financial statements. The unaudited consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments as necessary for the fair statement of the Company’s financial position as of June 30, 2026, results of operations and cash flows for the six months ended June 30, 2025 and 2026. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related footnotes thereto contained in the Company’s most recent consolidated annual financial statements filed with the SEC on Form 20-F. Results for the six months ended June 30, 2026 are not necessarily indicative of the results expected for the full fiscal year or for any future period.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Use of estimates</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The preparation of the Company’s unaudited consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Accounting estimates reflected in the Company’s unaudited consolidated financial statements include, but not limited to, inventory write-down, valuation of cryptocurrencies and cryptocurrency-denominated financial instruments, valuation of convertible notes denominated in Bitcoin, useful lives of property, plant and equipment and intangible assets, impairment of long-lived assets, valuation allowance for deferred tax assets and share-based compensation.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Principles of consolidation</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company’s unaudited consolidated financial statements include the financial statements of the Company and its subsidiaries. All transactions and balances among the Company and its subsidiaries have been eliminated upon consolidation.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Functional currency and foreign currency translation</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company uses Renminbi (“RMB”) as its reporting currency. The functional currency of the Company and its subsidiaries incorporated outside of the People’s Republic of China (“PRC”) is the United States dollar (“US$”), while the functional currency of the PRC entities in the Company is RMB as determined based on the criteria of ASC 830, “<i>Foreign Currency Matters”</i>.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Transactions denominated in other than the functional currencies are re-measured into the functional currency of the entity at the exchange rates prevailing on the transaction dates. Financial assets and liabilities denominated in other than the functional currency are re-measured at the balance sheet date exchange rate. The resulting exchange differences are included in the unaudited consolidated statements of operations and comprehensive income (loss).</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The financial statements of the Company are translated from the functional currency to the reporting currency, RMB. Assets and liabilities of the Company and its subsidiaries incorporated outside of PRC are translated into RMB at fiscal year-end exchange rates. Income and expense items are translated at average exchange rates prevailing during the fiscal year, representing the index rates stipulated by the People’s Bank of China. Translation adjustments arising from these are reported as foreign currency translation adjustments and are shown as a separate component of shareholders’ equity (deficit) on the unaudited consolidated financial statement.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Convenience translation</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> The United States dollar (“US$”) amounts disclosed in the accompanying financial statements are presented solely for the convenience of the readers. Translations of amounts from RMB into US$ were calculated at the rate of US$1.00=RMB6.8109 on June 30, 2026, representing the central parity rate on June 30, 2026 published by the People’s Bank of China. No representation is made that the RMB amounts could have been, or could be, converted into US$ at that rate on June 30, 2026, or at any other rate. </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Concentration of credit risk</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, receivable for cryptocurrencies collateral and derivative assets. The Company places its cash and cash equivalents and short-term investments with financial institutions with high credit ratings and quality. The Company manages credit risk of receivable for cryptocurrencies collateral and derivative assets through credit assessment of the counterparty and daily supervision and reconciliation of the asset status of the designated crypto wallets.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Fair value measurement</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company adopted the guidance of Accounting Standards Codification (“ASC”) 820 for fair value measurements which clarifies the definition of fair value, prescribes methods for measuring fair value, and establishes a fair value hierarchy to classify the inputs used in measuring fair value as follows:</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Level 2: Observable, market-based inputs, other than quoted prices, in active markets for similar assets or liabilities.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Level 3: Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">ASC 820 also describes three main approaches to measuring the fair value of assets and liabilities:</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">(1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">As of December 31, 2025 and June 30, 2026, the carrying values of current assets and current liabilities approximated their fair values reported in the consolidated balance sheets due to the short-term maturities of these instruments, except for the following.</p> <p style="font: 10pt Times New Roman, Times, Serif;

Right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. When determining the lease term, the Company includes options to extend or terminate the lease when it is reasonably certain that it will exercise that option, if any. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate, which it calculates based on the credit quality of the Company and by comparing interest rates available in the market for similar borrowings, and adjusting this amount based on the impact of collateral over the term of each lease.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company elected not to record assets and liabilities on its unaudited consolidated balance sheet for lease arrangements with terms of 12 months or less.

In accordance with ASC 718, the Company determines whether restricted shares or options should be classified and accounted for as an equity award. All grants of restricted shares and options to employees and directors classified as equity awards are recognized in the financial statements based on their grant date fair values. The value of the portion of the award that is ultimately expected to vest is recognized as compensation expense over the requisite service periods in the statements of operations. In addition, compensation expense must be recognized for the change in fair value of any awards modified, repurchased or cancelled after the grant date.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The fair value of stock options granted is estimated on the grant date using the Binomial or Black-Scholes model.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Income taxes</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company accounts for income taxes under the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and income tax bases of assets and liabilities and are measured using the tax income rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded if it is more likely than not that some portion or all of the deferred income tax assets will not be realized in the foreseeable future.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">In accordance with the provisions of ASC 740, “Income taxes”, the Company recognizes in its financial statements the impact of a tax position if a tax return position or future tax position is “more likely than not” to be sustained upon examination based solely on the technical merits of the position. Tax positions that meet the recognition threshold are measured using a cumulative probability approach, at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. Interest and penalties arising from underpayment of income taxes are computed in accordance with the applicable tax law and is classified in the unaudited consolidated statements of operations as income tax expense.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Noncontrolling interests</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">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.

ASC 260 requires companies to present basic and diluted earnings (loss) per share. Basic earnings (loss) per share is computed by dividing net income (loss) attributable to holders of ordinary shares by the weighted average number of ordinary shares outstanding during the period.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Diluted earnings (loss) per share is calculated by dividing net income (loss) attributable to ordinary shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalents shares outstanding during the period. Dilutive equivalent shares are excluded from the computation of diluted earnings (loss) per share if their effects would be anti-dilutive. Ordinary share equivalents consist of the ordinary shares issuable in connection with the Company’s ordinary shares issuable upon the conversion of the share-based awards, using the treasury stock method. For the six months ended June 30, 2025 and 2026, the potential ordinary shares associated with the outstanding options and warrants were not included in the computation of diluted net loss per share as their effect would have been anti-dilutive.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Segment Reporting</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> The Company uses the “management approach” in determining reportable segments. The management approach considers the internal organization and reporting used by the Company’s chief operating decision maker (“CODM”) for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. The Company’s CODM has been identified as the <span style="-sec-ix-hidden:fc_13673912;">chief executive officer</span> of the Company who reviews financial information of operating segments based on U.S. GAAP. The CODM now reviews results analyzed by revenue streams. This analysis is only presented at the revenue level with no allocation of direct or indirect costs. Consequently, the Company has determined that it has only one operating segment. The CODM evaluates performance for the Company’s single operating segment and decides how to allocate resources based on the Company’s consolidated net income (loss) as reported in the consolidated statements of operations and comprehensive income (loss). The measure of segment assets is reported on the consolidated balance sheets as total assets. The CODM allocates resources across the Company based on consolidated net income derived during the annual budgeting process and throughout the year in monitoring actual results compared to budget and updated forecasts. These results are used to assess segment performance. </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The operating segment financial information regularly reviewed by the CODM, including assets, revenues, expenses, profit or loss, and noncash items, is presented on a consolidated basis in the same amounts and using the same captions as those included in the consolidated statements of operations and comprehensive income (loss), consolidated balance sheets, and consolidated statements of cash flows. There are no additional segment expense categories regularly provided to the CODM. Therefore, there are also no amounts classified as other segment items requiring disclosure.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> Long-lived assets consist of cryptocurrencies, non-current, property, plant and equipment, right-of-use assets and intangible assets with finite lives.

The Company adopted ASU No. 2025-05 on January 1, 2026, which did not have a material impact on the consolidated financial statements.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Basis of preparation</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The unaudited consolidated financial statements of the Company have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for the complete consolidated financial statements. The unaudited consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments as necessary for the fair statement of the Company’s financial position as of June 30, 2026, results of operations and cash flows for the six months ended June 30, 2025 and 2026. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related footnotes thereto contained in the Company’s most recent consolidated annual financial statements filed with the SEC on Form 20-F. Results for the six months ended June 30, 2026 are not necessarily indicative of the results expected for the full fiscal year or for any future period.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Use of estimates</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The preparation of the Company’s unaudited consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Accounting estimates reflected in the Company’s unaudited consolidated financial statements include, but not limited to, inventory write-down, valuation of cryptocurrencies and cryptocurrency-denominated financial instruments, valuation of convertible notes denominated in Bitcoin, useful lives of property, plant and equipment and intangible assets, impairment of long-lived assets, valuation allowance for deferred tax assets and share-based compensation.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Principles of consolidation</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company’s unaudited consolidated financial statements include the financial statements of the Company and its subsidiaries. All transactions and balances among the Company and its subsidiaries have been eliminated upon consolidation.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Functional currency and foreign currency translation</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company uses Renminbi (“RMB”) as its reporting currency. The functional currency of the Company and its subsidiaries incorporated outside of the People’s Republic of China (“PRC”) is the United States dollar (“US$”), while the functional currency of the PRC entities in the Company is RMB as determined based on the criteria of ASC 830, “<i>Foreign Currency Matters”</i>.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Transactions denominated in other than the functional currencies are re-measured into the functional currency of the entity at the exchange rates prevailing on the transaction dates. Financial assets and liabilities denominated in other than the functional currency are re-measured at the balance sheet date exchange rate. The resulting exchange differences are included in the unaudited consolidated statements of operations and comprehensive income (loss).</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The financial statements of the Company are translated from the functional currency to the reporting currency, RMB. Assets and liabilities of the Company and its subsidiaries incorporated outside of PRC are translated into RMB at fiscal year-end exchange rates. Income and expense items are translated at average exchange rates prevailing during the fiscal year, representing the index rates stipulated by the People’s Bank of China. Translation adjustments arising from these are reported as foreign currency translation adjustments and are shown as a separate component of shareholders’ equity (deficit) on the unaudited consolidated financial statement.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Convenience translation</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> The United States dollar (“US$”) amounts disclosed in the accompanying financial statements are presented solely for the convenience of the readers. Translations of amounts from RMB into US$ were calculated at the rate of US$1.00=RMB6.8109 on June 30, 2026, representing the central parity rate on June 30, 2026 published by the People’s Bank of China. No representation is made that the RMB amounts could have been, or could be, converted into US$ at that rate on June 30, 2026, or at any other rate. </p> 6.8109 <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Concentration of credit risk</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, receivable for cryptocurrencies collateral and derivative assets. The Company places its cash and cash equivalents and short-term investments with financial institutions with high credit ratings and quality. The Company manages credit risk of receivable for cryptocurrencies collateral and derivative assets through credit assessment of the counterparty and daily supervision and reconciliation of the asset status of the designated crypto wallets.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Fair value measurement</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company adopted the guidance of Accounting Standards Codification (“ASC”) 820 for fair value measurements which clarifies the definition of fair value, prescribes methods for measuring fair value, and establishes a fair value hierarchy to classify the inputs used in measuring fair value as follows:</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Level 2: Observable, market-based inputs, other than quoted prices, in active markets for similar assets or liabilities.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Level 3: Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">ASC 820 also describes three main approaches to measuring the fair value of assets and liabilities:</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">(1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">As of December 31, 2025 and June 30, 2026, the carrying values of current assets and current liabilities approximated their fair values reported in the consolidated balance sheets due to the short-term maturities of these instruments, except for the following.</p> <p style="font: 10pt Times New Roman, Times, Serif;

As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate, which it calculates based on the credit quality of the Company and by comparing interest rates available in the market for similar borrowings, and adjusting this amount based on the impact of collateral over the term of each lease.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company elected not to record assets and liabilities on its unaudited consolidated balance sheet for lease arrangements with terms of 12 months or less. The Company recognizes lease expenses for such leases on a straight-line basis over the lease term.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Employee social security and welfare benefits</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Employees of the Company in the PRC are entitled to staff welfare benefits including pension, work-related injury benefits, maternity insurance, medical insurance, unemployment benefit and housing fund plans through a PRC government-mandated multi-employer defined contribution plan. The Company is required to contribute to the plan based on certain percentages of the employees’ salaries, up to a maximum amount specified by the local government.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">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.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Share-based compensation</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Restricted shares and options granted to employees and directors are accounted for under ASC Topic 718, “Compensation - Stock compensation” (“ASC 718”). In accordance with ASC 718, the Company determines whether restricted shares or options should be classified and accounted for as an equity award. All grants of restricted shares and options to employees and directors classified as equity awards are recognized in the financial statements based on their grant date fair values. The value of the portion of the award that is ultimately expected to vest is recognized as compensation expense over the requisite service periods in the statements of operations. In addition, compensation expense must be recognized for the change in fair value of any awards modified, repurchased or cancelled after the grant date.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The fair value of stock options granted is estimated on the grant date using the Binomial or Black-Scholes model.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Income taxes</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company accounts for income taxes under the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and income tax bases of assets and liabilities and are measured using the tax income rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded if it is more likely than not that some portion or all of the deferred income tax assets will not be realized in the foreseeable future.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">In accordance with the provisions of ASC 740, “Income taxes”, the Company recognizes in its financial statements the impact of a tax position if a tax return position or future tax position is “more likely than not” to be sustained upon examination based solely on the technical merits of the position. Tax positions that meet the recognition threshold are measured using a cumulative probability approach, at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. Interest and penalties arising from underpayment of income taxes are computed in accordance with the applicable tax law and is classified in the unaudited consolidated statements of operations as income tax expense.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Noncontrolling interests</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.25in;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">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 unaudited consolidated balance sheets and have been separately disclosed in the Company’s unaudited consolidated statements of operations and comprehensive income (loss).</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Comprehensive income (loss)</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Comprehensive income (loss) is defined as the changes in equity of the Company during a period from transactions and other events and circumstances excluding transactions resulting from investments from shareholders and distributions to shareholders. Comprehensive income (loss) for the periods presented includes net income (loss) and foreign currency translation adjustments.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Earnings (loss) per share</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The Company computes earnings (loss) per share in accordance with ASC 260, “Earnings per Share”. ASC 260 requires companies to present basic and diluted earnings (loss) per share. Basic earnings (loss) per share is computed by dividing net income (loss) attributable to holders of ordinary shares by the weighted average number of ordinary shares outstanding during the period.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">Diluted earnings (loss) per share is calculated by dividing net income (loss) attributable to ordinary shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalents shares outstanding during the period. Dilutive equivalent shares are excluded from the computation of diluted earnings (loss) per share if their effects would be anti-dilutive. Ordinary share equivalents consist of the ordinary shares issuable in connection with the Company’s ordinary shares issuable upon the conversion of the share-based awards, using the treasury stock method. For the six months ended June 30, 2025 and 2026, the potential ordinary shares associated with the outstanding options and warrants were not included in the computation of diluted net loss per share as their effect would have been anti-dilutive.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"><span style="font-weight: bold;"><i>Segment Reporting</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> The Company uses the “management approach” in determining reportable segments. The management approach considers the internal organization and reporting used by the Company’s chief operating decision maker (“CODM”) for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. The Company’s CODM has been identified as the <span style="-sec-ix-hidden:fc_13673912;">chief executive officer</span> of the Company who reviews financial information of operating segments based on U.S. GAAP. The CODM now reviews results analyzed by revenue streams. This analysis is only presented at the revenue level with no allocation of direct or indirect costs. Consequently, the Company has determined that it has only one operating segment. The CODM evaluates performance for the Company’s single operating segment and decides how to allocate resources based on the Company’s consolidated net income (loss) as reported in the consolidated statements of operations and comprehensive income (loss). The measure of segment assets is reported on the consolidated balance sheets as total assets. The CODM allocates resources across the Company based on consolidated net income derived during the annual budgeting process and throughout the year in monitoring actual results compared to budget and updated forecasts. These results are used to assess segment performance. </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;">The operating segment financial information regularly reviewed by the CODM, including assets, revenues, expenses, profit or loss, and noncash items, is presented on a consolidated basis in the same amounts and using the same captions as those included in the consolidated statements of operations and comprehensive income (loss), consolidated balance sheets, and consolidated statements of cash flows. There are no additional segment expense categories regularly provided to the CODM. Therefore, there are also no amounts classified as other segment items requiring disclosure.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;"> Long-lived assets consist of cryptocurrencies, non-current, property, plant and equipment, right-of-use assets and intangible assets with finite lives.

The EIT Law applies a uniform 25% enterprise income tax (“EIT”) rate to both foreign invested enterprises and domestic enterprises. Accordingly, the Company’s PRC subsidiaries are subject to the EIT rate of 25%. EIT grants preferential tax treatment to certain High and New Technology Enterprises (“HNTEs”). Under this preferential tax treatment, HNTEs are entitled to an income tax rate of 15%, subject to a requirement that they re-apply for HNTE status every three years. Zhejiang Nanomicro obtained the “high-tech enterprise” tax status in December 2021 and renewed the status in December 2024, which reduced its statutory income tax rate to 15% from December 2021 to December 2027. </p> <p style="font: 10pt Times New Roman, Times, Serif;

A full valuation allowance is recorded against net deferred tax assets. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the cumulative earnings and projected future taxable income in making this assessment. Recovery of the Company’s deferred tax assets is dependent upon the generation of future income, exclusive of reversing taxable temporary differences. </p> 0.0825 2000000 2000000 0.165 0.21 0.17 0.75 100000 100000 470000 0.50 470000 0.25 0.25 0.15 0.15 <p style="font: 10pt Times New Roman, Times, Serif;
