Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2.	Summary of Significant Accounting Policies

Basis of preparation

The accompanying consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for information pursuant to the rules and regulations of the SEC.

Significant accounting policies followed by the Company in the preparation of the accompanying consolidated financial statements are summarized below.

Use of estimates

The preparation of the Company’s 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.

Significant accounting estimates reflected in the Company’s consolidated financial statements including, but not limited to, inventory write-down, valuation of short-term investments, valuation of cryptocurrencies, receivable for cryptocurrencies collateral and borrowings denominated in cryptocurrencies, expected credit loss on receivable for cryptocurrencies collateral, 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.

Principles of consolidation

The Company’s 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.

Reclassification

Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications had no impact on net earnings and financial position.

Functional currency and foreign currency translation

The Company uses Renminbi (“RMB”) as its reporting currency. The functional currency of the Company and its subsidiaries incorporated outside of 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, “Foreign Currency Matters”.

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 consolidated statements of operations and comprehensive income (loss).

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 consolidated financial statement.

Convenience translation

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$1.00=RMB7.0288 on December 31, 2025, representing the central parity rate on December 31, 2025 published by the People’s Bank of China. No representation is made that the RMB amounts could have been, or could be, converted into US$ at that rate on December 31, 2025, or at any other rate.

Concentration of credit risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, and receivable for cryptocurrencies collateral. 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 through credit assessment of the counterparty lender and daily supervision and reconciliation of the asset status of the designated crypto wallets.

Fair value measurement

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:

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2: Observable, market-based inputs, other than quoted prices, in active markets for similar assets or liabilities.

Level 3: Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

ASC 820 also describes three main approaches to measuring the fair value of assets and liabilities:

(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.

As of December 31, 2024 and 2025, 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.

Related party transactions

Parties are considered to be related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operational decisions. Parties are also considered to be related if they are subject to common control or common significant influence. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties. Related parties may be individuals or corporate entities.

Transactions involving related parties cannot be presumed to be carried out on an arm’s-length basis, as the requisite conditions of competitive, free market dealings may not exist. Representations about transactions with related parties, if made, shall not imply that the related party transactions were consummated on terms equivalent to those that prevail in arm’s-length transactions unless such representations can be substantiated. It is not, however, practical to determine the fair value of amounts due from/to related parties due to their related party nature.

Cash and cash equivalents

Cash and cash equivalents include deposits in banks and other financial institutions that are unrestricted to withdrawal or use, and which have original maturities of three months or less. As of December 31, 2024 and 2025, cash and cash equivalents was RMB32,431,081 and RMB8,502,357, respectively.

Restricted cash

Restricted cash mainly represents the bank deposit frozen by the court as a result of legal proceedings. As of December 31, 2024 and 2025, the Company had restricted cash of RMB418,722 and RMB1,347,795, respectively.

Short-term investments

Investment in equity securities with readily determinable fair value

The Company hold investments in equity securities of a publicly listed company, for which the Company does not have significant influence. Investments in equity securities with readily determinable fair values are measured at fair value and any changes in fair value are recognized in other income (expenses).

Investment in warrants

The Company hold investments in stock warrants of a publicly listed company, for which the Company does not have significant influence. The warrants are measured at fair value and any changes in fair value are recognized in other income (expenses).

Inventories, net

Inventories, consist of raw materials, work in process and finished goods. Inventories are stated at the lower of cost and net realizable value. Cost of inventory is determined using the weighted average cost method. Adjustments are recorded to write down the cost of inventory to the estimated net realizable value due to slow-moving and obsolete inventory, which is dependent upon factors such as historical and forecasted consumer demand, and promotional environment.

Prepayments

Prepayments primarily consist of advances to suppliers for future inventory purchases and prepaid processing fees and prepaid expenses for research and development activities.

Cryptocurrencies

Certain cryptocurrencies were included in non-current assets on the consolidated balance sheets due to the Company’s intent to retain them for long-term strategic reserve. Other cryptocurrencies held with the intent to fund operating expenses and working capital are included in current assets on the consolidated balance sheets. In addition, cryptocurrencies that are pledged as collateral are reported as “Receivable for cryptocurrencies collateral” and classified as current assets on the consolidated balance sheets, consistent with the Company’s intent to fund operating expenses.

As a result of adopting ASC 350-60, Intangibles — Goodwill and Other, (“ASC 350-60”) on January 31, 2024 following modified retrospective method, cryptocurrencies are measured at fair value as of each reporting period. The fair value of cryptocurrencies are measured using the period-end closing price from the principal market, Binance, in accordance with ASC 820, Fair Value Measurement (“ASC 820”). The changes in cryptocurrencies valuation due to remeasurement in fair value within each reporting period are reflected on the consolidated statements of operations and comprehensive income (loss) as “Change in fair value of cryptocurrencies”. The cost basis of cryptocurrencies is determined using average cost method of accounting.

The purchases and disposals of cryptocurrencies are included within investing activities in the consolidated statements of cash flows.

Receivable for cryptocurrencies collateral

The receivable for cryptocurrencies collateral represents the cryptos posted as collateral to the lender who has the rights to, among other activities, lend or re-hypothecate such cryptos at the sole discretion of the lender and for which the lender has an obligation to return to the Company at maturity of the loan.

The receivable for cryptocurrencies collateral is initially measured upon transfer at fair value and subsequently remeasured at fair value at the end of each reporting period. The changes in fair value are recognized on the consolidated statements of operations, in accordance with ASC 350-60.

In estimating the allowance for credit losses, the Company applies the current expected credit loss (“CECL”) model, which requires the measurement of lifetime expected credit losses on the amortized costs of the financial assets.

To estimate the allowance for credit loss of receivable for cryptocurrencies collateral, as the Company has no historical experience with similar assets, the allowance is determined using a combination of industry data, peer analysis, and forward-looking information about economic conditions and the creditworthiness of the counterparty.

The Company incorporates relevant qualitative factors, such as the nature of the receivable, the characteristics of the counterparty, and any observable market indicators, to assess the expected collectability of the receivable for cryptocurrencies collateral. The estimation process also includes reasonable and supportable forecasts to account for future economic conditions and any anticipated impact on the receivable. As of December 31, 2024 and 2025, no allowance for credit loss was recorded for receivable for cryptocurrencies collateral.

Borrowings denominated in cryptocurrencies

Borrowings denominated in cryptocurrencies is accounted for as hybrid instrument with a debt host contract and embedded derivatives linked to the fair value of cryptocurrencies. The Company measures this hybrid instrument at fair value through the election of fair value option. The fair value is measured as the spot price of the underlying cryptocurrencies in which the borrowing is denominated. Election of the fair value option is generally irrevocable unless an event occurs that gives rise to a new basis of accounting for that instrument. The gain or loss from change in fair value of borrowings denominated in cryptocurrencies are reported as a separate caption in other income (expenses) on the consolidated statements of operations and comprehensive income (loss).

Property, plant and equipment, net

Property, plant and equipment are stated at historical cost less accumulated depreciation and impairment loss, if any. Depreciation is calculated using the straight-line method over their estimated useful lives. The estimated useful lives are as follows:

Machinery and electronic equipment		3 to 10 years
Office furniture		5 years
Transportation equipment		4 years
Buildings and facilities attached to buildings		20 years

Leasehold improvements are depreciated using the straight-line method over the shorter of the estimated useful life of the asset or the remaining lease term.

Intangible asset, net

The Company’s intangible asset with definite useful lives primarily consists of a franchise right and land use right. According to the law of PRC, the government owns all the land in the PRC. Companies or individuals are authorized to possess and use the land only through land use rights granted by the Chinese government for a specified period of time. The Company amortizes its franchise right and land use right on a straight-line basis over the contractual term. The estimated useful lives are as follows:

Franchise right		2 years
Land use right		50 years

Impairment of long-lived assets

For long-lived assets including primarily property, plant and equipment, right-of-use assets, and intangible assets with finite lives, the Company evaluates for impairment whenever events or changes (triggering events) indicate that the carrying amount of an asset may no longer be recoverable. The Company recognizes an impairment loss when the sum of expected undiscounted future cash flows is less than the carrying amount of the asset. The amount of impairment is measured as the difference between the asset’s estimated fair value and its book value. For the years ended December 31, 2023, 2024 and 2025, no impairment of long-lived assets was recognized.

Treasury shares

The Company accounts for treasury shares using the cost method. Under this method, the cost incurred to purchase the shares is recorded in the treasury shares account on the consolidated balance sheets.

Revenue from contracts with customers

Consistent with the criteria of ASC 606 “Revenue from Contracts with Customers”, the Company recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services. Revenue consists of the invoiced value for the sales net of value-added tax (“VAT”), business tax and applicable local government levies.

Product sales revenue

The Company generates revenue primarily from the sale of product solutions by integrating its self-designed IC products (e.g., high throughput computing, or HTC, solutions) directly to a customer, such as a business or individual engaged in mining activities.

The Company recognizes revenue at a point in time when the control of the products has been transferred to customers. The transfer of control is considered complete when products have been picked up by or shipped to customers. The Company’s sales arrangements usually require prepayment before the delivery of products. The advance payment is not considered a significant financing component. The Company elected to account for shipping and handling fees as a fulfillment cost. The product sales contracts generally include product warranty provisions. The Company did not accrue warranty liabilities for the product sales as the financial impacts of the warranty have historically been and are expected to continue to be immaterial. The Company estimates sales return based on historical experiences and there was no allowance for sales return recorded during the years ended December 31, 2023, 2024 and 2025.

Service revenue

The Company also generates revenue from its design and technical services under separate contracts. Revenues from the design and technical service to the customers are recognized at a point in time when services are provided.

Revenue disaggregation

In accordance with ASC 606, the Company disaggregates revenue from contracts with customers by revenue stream. The Company determined that disaggregating revenue into these categories meets the disclosure objective in ASC 606 which is to depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by regional economic factors. The following table summarizes the net revenues generated from different revenue streams:

	For the Years Ended December 31,
	2023		2024		2025
	RMB		RMB		RMB
Product sales revenue		71,321,462		34,096,450		26,633,026
Service revenue		7,013,914		6,499,466		373,718
Net revenues		78,335,376		40,595,916		27,006,744

Contract liabilities

Contract liabilities are recorded when consideration is received from a customer prior to transferring the control of goods or services to the customer. As of December 31, 2024 and 2025, the Company recorded contract liabilities of RMB98,895,905 and RMB69,314,154, respectively, which were presented as advance from customers on the accompanying consolidated balance sheets. During the years ended December 31, 2023, 2024 and 2025, the Company recognized RMB23,740,945, RMB9,765,766 and RMB20,805,240 from the opening balance of contract liabilities as revenue, respectively.

Cost of revenues

Amounts recorded as cost of revenue relate to direct expenses incurred in order to generate revenue. Such costs are recorded as incurred. Cost of revenues consists of product costs and service costs. Product costs include costs of raw material, contract manufacturers for production, shipping and handling costs, and warehousing costs. Service costs include labor costs and material costs. During the years ended December 31, 2023, 2024 and 2025, the Company recorded inventory write-down of RMB60,767,978, RMB10,914,374 and RMB32,637,101 as cost of revenues, respectively.

Selling and marketing expenses

Selling and marketing expenses consist primarily of advertising and promotion, salaries, and shipping and handling costs incurred during the selling activities. Advertising and transportation expenses are charged to expense as incurred.

Advertising and promotion costs in the amounts of RMB1,278,586, RMB364,253 and RMB656,386 for the years ended December 31, 2023, 2024 and 2025, respectively, are included in selling and marketing expenses.

Shipping and handling costs amounting to RMB2,122,358, RMB968,713 and RMB115,867 for the years ended December 31, 2023, 2024 and 2025, respectively, are included in selling and marketing expenses.

Research and development expenses

Research and development expenses consist primarily of salary and welfare for research and development personnel, raw materials used, consulting and contractor expenses, testing and processing expenses and other expenses in associated with research and development activities. The Company recognizes research and development expenses as expense when incurred.

Leases

Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. 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.

The Company elected not to record assets and liabilities on its 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.

Employee social security and welfare benefits

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.

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.

Share-based compensation

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.

The fair value of stock option granted is estimated on the grant date using the Binomial or Black-Scholes model.

Income taxes

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.

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 consolidated statements of operations as income tax expense.

Noncontrolling interests

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 income (loss).

Comprehensive income (loss)

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.

Earnings (loss) per share

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 year.

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 year. 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.

Segment Reporting

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 chief executive officer of the Company who reviews financial information of operating segments based on U.S. GAAP. The CODM now reviews results analyzed by marketing channel. 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 (loss) 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.

The operating segment financial information regularly reviewed by the CODM, inclusive assets, revenues, expenses, profit or loss, and noncash items are presented on a consolidated basis in the same amount 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.

Long-lived assets consist of cryptocurrencies, property, plant and equipment, right-of-use assets, intangible assets with finite lives and other non-current assets. As of December 31, 2025, the long lived assets of RMB424,743,318 belong to subsidiaries located in BVI. The remaining long-lived assets were located in PRC.

For the years ended December 31, 2023, 2024 and 2025, the Company’s net revenues by geographical location of customers are as follows:

	For the Years Ended December 31,
	2023		2024		2025

Recently adopted or issued accounting pronouncements

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvement to Income Tax Disclosures” to enhance the transparency and decision usefulness of income tax disclosures, primarily related to the rate reconciliation and income taxes paid information. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, on a prospective basis. Early adoption is permitted. The Company adopted ASU No. 2023-09 on January 1, 2025, which did not have a material impact on the consolidated financial statements. See Note 19.

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosure (Subtopic 220-40): Disaggregation of Income Statement Expenses”, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. The ASU is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU No. 2024-03.

In July 2025, the FASB issued ASU No. 2025-05, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets”, which provides a practical expedient for estimating expected credit losses for current accounts receivable and current contract assets. This ASU is effective for fiscal years beginning after December 15, 2025, and interim periods within those fiscal years, with early adoption permitted. ASU No. 2025-05 should be applied prospectively. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements and related disclosures and expects no material change if adopting ASU No. 2025-05.

Earnings (Loss) Per Share [Abstract]

Earnings (loss) per share

18.

Earnings (loss) per share

The calculation of basic earnings (loss) per share is based on the income (loss) attributable to ordinary shareholders of the Company and weighted-average number of ordinary shares outstanding for the years ended December 31, 2023, 2024 and 2025.

Diluted earnings (loss) per share is computed using the weighted average number of ordinary shares and dilutive potential ordinary shares outstanding during the respective periods. For the year ended December 31, 2025, the warrants issued for a weighted average number of 2,348,554 shares could potentially dilute earnings per share but were not included in the computation of diluted net income per share as their effect would have been anti-dilutive.

The following reflects the income and share data used in the basic and diluted earnings (loss) per ordinary share computations:

	For the years ended December 31,
	2023			2024			2025
	RMB			RMB			RMB
Earnings (loss) attributable to ordinary shareholders of the Company		(252,823,772	)		(113,187,048	)		135,466,040

Commitments and contingencies

Operating lease commitments

The information of lease commitments is provided in Note 10.

Contingencies

The Company is subject to litigation matters from time to time in the normal cause of business. The Company’s legal counsel and the management routinely assess the likelihood of adverse judgments and outcomes to these matters, as well as ranges of probable losses. Accruals are recorded for these matters to the extent that management concludes a loss is probable and the financial impact, should an adverse outcome occur, is reasonable estimable. The Company has not recorded any material liabilities in this regard as of December 31, 2024 and 2025.

In July 2025, a customer filed a civil action against one of the Company’s subsidiaries at the People’s Court of Shangcheng District, Hangzhou City, for a sales contract dispute, claiming the Company breached the contract and demanding a return of payment of RMB4,965,147 including related interests. Given the nature of the case, as of the date of this annual report, the amount liable by the Company in the event of an unfavorable outcome cannot be reasonably estimated.

The Company believes they have strong arguments against the claim and will defend vigorously.

Bank accounts of the Company were judicially frozen by the court as a result of the legal proceedings. The frozen amount as of December 31, 2025 and the date of this annual report was RMB1,347,795 and nil, respectively.

Statutory Reserves [Abstract]

Statutory reserves

16.

Statutory reserves

The Company’s subsidiaries incorporated in the PRC are required on an annual basis to make appropriations of retained earnings set at certain percentage of after-tax profit determined in accordance with PRC accounting standards and regulations (“PRC GAAP”).

Appropriation to the statutory general reserve should be at least 10% of the after tax net income determined in accordance with the legal requirements in the PRC until the reserve is equal to 50% of the entities’ registered capital. The Company is not required to make appropriation to other reserve funds and the Company does not have any intentions to make appropriations to any other reserve funds.

The general reserve fund can only be used for specific purposes, such as offsetting the accumulated losses, enterprise expansion or increasing the registered capital. Appropriations to the general reserve funds are classified in the consolidated balance sheets as statutory reserves.

There are no legal requirements in the PRC to fund these reserves by transfer of cash to restricted accounts, and the Company has not done so.

Relevant laws and regulations permit payments of dividends by the PRC subsidiaries and affiliated companies only out of their retained earnings, if any, as determined in accordance with respective accounting standards and regulations. Accordingly, the above balances are not allowed to be transferred to the Company in terms of cash dividends, loans or advances.

The Company has made nil appropriations to statutory reserve for the years ended December 31, 2023, 2024 and 2025.

Share-based compensation

2022

Share Incentive Plan

In June 2022, our shareholders and board of directors adopted our 2022 share incentive plan, or the 2022 Plan, which has become effective upon the completion of our initial public offering, to motivate, attract and retain the best available personnel, provide additional incentives to employees, directors and consultants and promote the success of our business. Under the 2022 Plan, the maximum aggregate number of Class A ordinary shares which may be issued pursuant to all awards under such plan is 518,950, which constitutes 10% of the total issued and outstanding shares of our company on a fully-diluted basis as of the date of adoption.

Restricted Stock Units (“RSUs”)

On November 1, 2021, the Board of the Company approved the establishment of an employee benefit trust for the purpose of holding the Company’s ordinary shares to be transferred to the recipient employees and directors of the share awards granted prior to the establishment of the 2022 Plan. In January 2022, Mr. Jianping Kong and other original shareholders of Zhejiang Haowei transferred a total of 562,668 ordinary shares held by them on behalf of the respective equity reward holders to Nanometa Ltd. (“Nanometa”), the nominee of the employee benefit trust. 165,664 shares held by Nanometa were transferred to the recipient employees and directors. As of December 31, 2025, a total of 335,710 shares were still held by Nanometa, which comprises of: 1) 310,045 shares held on behalf of and transferable to the recipient employes and directors upon request; and 2) 25,665 shares unassigned due to forfeiture of share awards. All RSUs have been vested or forfeited as of December 31, 2024.

Options

On April 27, 2023, the Company granted a series of options under the 2022 share incentive plan: 1) the Company granted employees options to purchase a total of 22,522 Class A ordinary shares of the Company with an exercise price of US$0.002 per share. The options granted have a contractual term of 10 years. For the reward, 33.3% will be vested on April 27, 2024; 33.3% will be vested on April 27, 2025; and 33.3% will be vested on April 27, 2026; 2) the Company granted employees options to purchase a total of 7,787 Class A ordinary shares of the Company with an exercise price of US$0.002 per share.

The options granted have a contractual term of 10 years. The options were fully vested and exercisable at the grant date. The options in 1) and 2) described above were subject to performance conditions based on the result of an annual performance review of the grantee in accordance with the predetermined performance targets. The Company estimated the annual performance review result for each grantee and recognized the related compensation expenses.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]

Cybersecurity Risk Management and Strategy

To preserve the confidentiality, integrity and availability of our information systems, safeguard our assets, data, intellectual property and network infrastructure, while meeting regulatory requirements, it is crucial to effectively manage cybersecurity risks. To achieve this, we have implemented a comprehensive cybersecurity risk management framework, which is integrated in our overall enterprise risk management system and processes and is internally managed.

Our dedicated IT staff is tasked with assessing, identifying and managing risks related to cybersecurity threats and is responsible for:

●

risk assessments designed to help identify material cybersecurity risks to our critical systems, information, products, services and our broader enterprise IT environment;

●

development of risk-based action plans to manage identified vulnerabilities and implementation of new protocols and infrastructure improvements;

●

cybersecurity incident investigations;

●

monitoring threats to sensitive data and unauthorized access to our systems;

●

secure access control measures applied to critical IT systems, equipment and devices, designed to prevent unauthorized users, processes and devices from assessing IT systems and data;

●

developing and executing protocols to ensure that information regarding cybersecurity incidents is promptly shared with the board of directors, as appropriate, to allow for risk and materiality assessments and to consider disclosure and notice requirements; and

●

developing and implementing training on cybersecurity, information security and threat awareness.

There were no cybersecurity incidents during the year ended December 31, 2025, that resulted in an interruption to our operations, known losses of any critical data or otherwise had a material impact on our strategy, financial condition or results of operations. However, the scope and impact of any future incident cannot be predicted. See “Item 3. Key Information—D. Risk Factors” for more information on how material cybersecurity attacks may impact our business.

The applicable tax rate is 8.25% on assessable profits arising in or derived from Hong Kong up to HKD2,000,000 and 16.5% on any part of assessable profits over HKD2,000,000. These companies did not make any provisions for Hong Kong profit tax as there were no assessable profits derived from or earned in Hong Kong since inception.

The company did not make any provisions for Singapore income tax as there were no assessable profits derived from or earned in Singapore since inception.

PRC

The Company’s subsidiaries incorporated in the PRC are subject to PRC Enterprise Income Tax (“EIT”) on the taxable income in accordance with the relevant PRC income tax laws. A new enterprise income tax law (the “EIT Law”) in the PRC was enacted and became effective on January 1, 2008. 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.

	RMB			RMB			RMB
PRC		(209,783,759	)		(88,852,369	)		(97,453,535	)

Income (loss) before income tax provision		(254,369,448	)		(119,539,049	)		125,947,598

Significant component of deferred tax assets are as follows:

	As of December 31,
	2024			2025
Net operating loss carryforward		98,783,665			118,846,734
Accrued expense and others		9,688,509			(3,698,621	)

Deferred tax assets		158,948,049			165,724,739
Less: valuation allowance		(158,948,049	)		(165,724,739	)
Deferred tax assets		—			—

As of December 31, 2025, the Company had net operating loss carryforward of approximately RMB568,188,165 which mainly arose from the Company’s subsidiaries established in the PRC. These net operating losses can be carried forward to offset future taxable income and will expire during the period from 2026 to 2035. The provision of valuation allowance for the years ended December 31, 2023, 2024 and 2025 were RMB47,333,923, RMB31,087,058 and RMB9,831,853, respectively. The reversal of valuation allowance for the years ended December 31, 2023, 2024 and 2025 were RMB117,051, RMB257,501, and RMB3,055,163, respectively.

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.

Uncertain tax positions

The tax authority of the PRC Government conducts periodic and ad hoc tax filing reviews on business enterprises operating in the PRC after those enterprises complete their relevant tax filings. In general, the PRC tax authority has up to five years to conduct examinations of the tax filings of the Company’s PRC entities. Accordingly, the PRC subsidiaries’ tax years of 2020 through 2024 remain open to examination by the respective tax authorities. It is therefore uncertain as to whether the PRC tax authority may take different views about the Company’s PRC entities’ tax filings, which may lead to additional tax liabilities.

The Company evaluates each uncertain tax position (including the potential application of interest and penalties) based on the technical merits, and measure the unrecognized benefits associated with the tax positions. As of December 31, 2024 and 2025, the Company did not have any significant unrecognized uncertain tax positions.
