Summary of Significant Accounting Policies

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, 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.

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$1.00=RMB7.0827 on December 31, 2023, representing the central parity rate on December 31, 2023 published by the People’s Bank of China. No representation is made that the RMB amounts could have been, or could be, converted into US$ at that rate on December 31, 2023, 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. The Company places its cash and cash equivalents with financial institutions with high credit ratings and quality.

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.

Financial instruments included in current assets and current liabilities are reported in the consolidated balance sheets at face value or cost, which approximate to fair value because of their short-term maturities.

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 cash in bank and time deposits placed with banks or other financial institutions, which have original maturities of three months or less and are readily convertible to known amounts of cash. As of December 31, 2022 and 2023, cash and cash equivalents in banks was RMB87,811,272 and RMB48,164,664, respectively.

Restricted cash

Restricted cash mainly represents the bank deposit frozen by the court as a result of legal proceedings. As of December 31, 2022 and 2023, the Company had restricted cash RMB48,112 and RMB417,990, respectively.

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, prepaid processing fees and prepaid expenses for research and development activities.

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:

Computers and electronic equipment		2 to 3 years
Office furniture		5 years
Transportation equipment		4 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.

Construction in progress represents assets under construction. All direct costs relating to the construction are capitalized as construction in progress. Construction in progress is not depreciated until the asset is placed in service.

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 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, 2021, 2022 and 2023, no impairment of long-lived assets was recognized.

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, 2021, 2022 and 2023.

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,
	2021		2022		2023
	RMB		RMB		RMB
Product sales revenue		39,440,897		920,653,911		71,321,462
Service revenue		—		62,514,987		7,013,914
Net revenues		39,440,897		983,168,898		78,335,376

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, 2022 and 2023, the Company recorded contract liabilities of RMB124,469,097 and RMB107,826,617, respectively, which were presented as advance from customers on the accompanying consolidated balance sheets. During the years ended December 31, 2021, 2022 and 2023, the Company recognized RMB4,241,270, RMB804,875,532 and RMB23,740,945 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, 2021, 2022 and 2023, the Company recorded inventory write-down of RMB26,753,768, RMB184,073,191 and RMB60,767,978 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 RMB992,996, RMB10,901,200 and RMB1,278,586 for the years ended December 31, 2021, 2022 and 2023, respectively, are included in selling and marketing expenses.

Shipping and handling costs amounting to RMB371,769, RMB4,233,084 and RMB2,122,358 for the years ended December 31, 2021, 2022 and 2023, 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 for making operating decisions and assessing performance as the source for determining the Company’s reportable segments. The Company’s chief operating decision maker has been identified as the chief executive officer of the Company who reviews financial information of operating segments based on U.S. GAAP. The chief operating decision maker 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. For the years ended December 31, 2021, 2022 and 2023, substantially all of the Company’s long-lived assets are located in the PRC. The Company’s net revenues by geographical location of customers are as follows:

	For the Years Ended December 31,
	2021		2022		2023
	RMB		RMB		RMB
PRC		37,430,935		906,347,962		57,485,526

Others		1,641,430		60,542,584		13,734,497
Net revenues		39,440,897		983,168,898		78,335,376

Recently adopted or issued accounting pronouncements

In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments (Topic 326)”, and issued subsequent amendments to the initial guidance, transitional guidance and other interpretive guidance between November 2018 and March 2020 within ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-11, ASU 2020-02 and ASU 2020-03. ASU 2016-13 introduces new guidance for credit losses on instruments within its scope, which significantly changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life, instead of when incurred. The Company adopted ASU 2016-13 on January 1, 2023 and the adoption did not have a material impact on its consolidated financial statements.

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements – Codification Amendment in Response to the SEC’s Disclosure Update and Simplification Initiative.” This ASU modified the disclosure and presentation requirements of a variety of codification topics by aligning them with the SEC’s regulations. The amendments to the various topics should be applied prospectively, and the effective date will be determined for each individual disclosure based on the effective date of the SEC’s removal of the related disclosure. If the SEC has not removed the applicable requirements from Regulation S-X or Regulation S-K by June 30, 2027, then this ASU will not become effective. Early adoption is prohibited. The Company does not expect the amendments of this accounting standard update to have a material impact on its consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the potential effect that the updated standard will have on its consolidated financial statement disclosures.

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 is currently evaluating the impact of this accounting standard update on its consolidated financial statements and related disclosures.

Commitments and contingencies

Operating lease commitments

The information of lease commitments is provided in Note 8.

Purchase commitments

The Company’s commitments related to the construction in progress but not yet reflected in the consolidated financial statements were RMB39,119,300 as of December 31, 2023 and were expected to be incurred within one year.

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, 2022 and 2023.

On September 8, 2023, a customer named one of the Company’s subsidiaries as the defendant of a claim in the General Division of the High Court of the Republic of Singapore. This customer alleged that the Company failed to make timely delivery for products purchased and such products did not function as expected, demanding a return of payments of US$300,000 with relevant damages, interests and costs. Given the nature of the case, as of the filing date, the amount liable by the Company in the event of an unfavorable outcome cannot be reasonably estimated.

On December 25, 2023, three of the Company’s subsidiaries were named as defendants along with others unaffiliated to the Company in a civil action filed at the People’s Court of Yuhuatai District, Nanjing City. The plaintiff of such civil action alleged that it entered into a sales contract for the Company’s products with one of the defendants who purportedly purchased the Company’s products for resale and failed to make timely delivery. The plaintiff seeks to rescind the sales contract with this defendant and demands a return of payments of RMB47,000,000 with interests accrued by all defendants including the Company’s three subsidiaries. Given the nature of the case, as of the filing date, 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 these claims and will defend vigorously.

Two 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, 2023 and the date of this annual report was RMB417,990 and RMB418,201, respectively.

British Virgin Islands

The holding companies incorporated in the British Virgin Islands are not subject to tax on income or capital gains under current British Virgin Islands law. In addition, upon payments of dividends by these entity to the shareholders, no British Virgin Islands withholding tax will be imposed.

Hong Kong

The Company’ subsidiaries incorporated in Hong Kong are subject to Hong Kong Profits Tax on the taxable income as reported in its statutory financial statements adjusted in accordance with relevant Hong Kong tax laws. 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.

United States (“US”)

The Company’s subsidiary in the US is subject to profits tax at 21% statutory tax rate with respect to the profit generated from the US. The company did not make any provisions for the US profit tax as there were no assessable profits derived from or earned in the US since inception.

Singapore

The company incorporated in Singapore is subject to Singapore Profits Tax on the taxable income as reported in its statutory financial statements adjusted in accordance with relevant Singapore tax laws. The applicable tax rate is 17% in Singapore, with 75% of the first SGD100,000 (approximately RMB470,000) and 50% of the next SGD100,000 (approximately RMB470,000) taxable income exempted from income tax. 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, which reduced its statutory income tax rate to 15% from December 2021 to December 2024.

A reconciliation between the effective income tax rate and the PRC statutory income tax rate is as follows:

	For the Years Ended December 31,
	2021			2022			2023
PRC statutory income tax rates		25.00	%		25.00	%		25.00	%
Effect of expenses not deductible for tax purposes		(0.22	)%		0.91	%		(0.42	)%
Effect of additional deduction of research and development expense		15.18	%		(64.43	)%		5.98	%
Effect of income tax exemptions and reliefs		(13.14	)%		(56.77	)%		(5.71	)%
Recovery from deferred income tax assets		0.00	%		(97.39	)%		0.05	%
Effect of valuation allowance on deferred income tax assets		(26.35	)%		171.26	%		(23.52	)%
Income tax difference under different tax jurisdictions		(0.47	)%		21.42	%		(1.37	)%
Total		0.00	%		0.00	%		0.01	%

The provision for income taxes consists of the following:

	For the Years Ended December 31,
	2021		2022		2023
	RMB		RMB		RMB
Current income tax expense (benefit)		—		—		(17,394	)
Deferred tax expense		—		—		—
Income tax expense		—		—		(17,394	)

Significant component of deferred tax assets are as follows:

	As of December 31,
	2022			2023
Net operating loss carryforward		63,038,127			77,373,944
Accrued expense and others		(29,335,373	)		(282,843	)
Inventory impairment		47,198,866			51,027,391
Deferred tax assets		80,901,620			128,118,492
Less: valuation allowance		(80,901,620	)		(128,118,492	)
Deferred tax assets		—			—

The provision of valuation allowance for the years ended December 31, 2021, 2022 and 2023 were RMB42,631,572, RMB24,519,326 and RMB47,333,923, respectively. The reversal of valuation allowance for the years ended December 31, 2021, 2022 and 2023 were nil, RMB6,100,147, and RMB117,051, 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 2019 through 2022 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 31,2022 and 2023, the Company did not have any significant unrecognized uncertain tax positions.

Statutory Reserves

13.

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, RMB6,647,109 and nil appropriations to statutory reserve for the years ended December 31, 2021, 2022 and 2023.

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, 2021, 2022 and 2023.

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, 2023, the options granted under the 2022 share incentive plan for a weighted average number of 312,386 shares could potentially dilute earnings (loss) per share but were not included in the computation of diluted net loss per share due to their antidilutive effects resulted from net loss.

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

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 5,189,500, which constitutes 10% of the total issued and outstanding shares of our company on a fully-diluted basis as of the date of adoption.

Shareholders’ equity (deficit)

On January 8, 2021, Nano Labs Ltd was incorporated in the Cayman Islands. The authorized share capital of the Company is 250,000,000 ordinary shares with par value of US$0.0002 each after giving effects of the reverse stock split as described in Note 1.

In April and May 2021, the Company entered into agreements with fourteen new shareholders to issue a total of 10,375,500 ordinary shares for total cash proceeds of RMB 81,000,000 (approximately US$12,600,000). In August 2021, the Company entered into agreements with six new shareholders to issue a total of 1,895,000 ordinary shares for total consideration of US$18,950,000 (approximately RMB122,300,000).

Immediately prior to the completion of the initial public offering (“IPO”) on July 12, 2022, the Company adopted a dual-class share structure, consisting of Class A ordinary shares and Class B ordinary shares, with par value of US$0.0002 per share. 28,589,078 ordinary shares, beneficially owned by Mr. Jianping Kong and Mr. Qifeng Sun, the founders of the Company, were re-designated into Class B ordinary shares on a one-for-one basis, and the remaining 23,305,924 ordinary shares were re-designated into Class A ordinary shares on a one-for-one basis.

Each Class A ordinary share is entitled to one vote per share and each Class B ordinary share is entitled to 15 votes per share. Each Class B ordinary share is convertible at any time into one Class A ordinary share, while Class A ordinary shares are not convertible into Class B ordinary shares.

On July 14, 2022, the Company completed the IPO with new issuance of ADSs representing 1,770,000 Class A ordinary shares at a price of US$11.50 per ADS and per ordinary share for gross proceeds of approximately US$20.4 million.

Organization and Nature of Operations [Abstarct]

Organization and nature of operations

Organization and nature of operations

Nano Labs Ltd (“Nano Labs”), incorporated on January 8, 2021, is a holding company, as an exempted company with limited liability in the Cayman Islands. Nano Labs principally engages in fabless integrated circuit (“IC”) design and sale of product solutions by integrating its self-designed IC products in the People’s Republic of China (“PRC”) and other countries and regions. The Company utilizes third-party suppliers to fabricate, pack and test the IC products.

Prior to the incorporation of the Company, the Company’s business was carried out by Zhejiang Haowei Technology Co., Ltd. (“Zhejiang Haowei”) and its subsidiaries. Zhejiang Haowei was established by Mr. Jianping Kong, the principal shareholder, chairman and chief executive officer, in July 2019. Nano Labs underwent a series of onshore and offshore reorganizations, which were completed in September 2021 (the “Reorganization”).

Immediately before and after the Reorganization, the controlling shareholders of Zhejiang Haowei controlled Zhejiang Haowei and Nano Labs; therefore, for accounting purposes, the Reorganization is accounted for as a transaction of entities under common control. Accordingly, the accompanying consolidated financial statements have been prepared as if the current corporate structure had been in existence throughout the periods presented.

Nano Labs and its consolidated subsidiaries are collectively referred to herein as the “Company”, “we” and “us”, unless specific reference is made to an entity.

Reverse stock split

On January 31, 2024, a two-for-one reverse stock split (the “reverse stock split”) of the Company’s issued and outstanding ordinary shares, restricted stock units and stock options was effected. The par value of Class A and Class B ordinary shares were changed from $0.0001 to $0.0002. All information related to the Company’s ordinary shares, restricted stock units and stock options, as well as all per share data included in these financial statements and footnotes have been retrospectively adjusted to reflect the reverse stock split for all periods presented. Also see Note 19.

Liquidity

During the year ended December 31, 2023, the Company incurred net loss of RMB254 million, and the net cash used in operating activities was RMB133 million. As of December 31, 2023, the Company had a working capital deficit of RMB117 million and accumulated deficit of RMB452 million. Historically, the Company has relied principally on both operational sources of cash and non-operational sources of financing from investors to fund its operations and business development. The Company’s ability to continue as a going concern is dependent on management’s ability to successfully execute its business plan, which includes increasing revenues while controlling costs and operating expenses, as well as, generating operational cash flows and continuing to gain support from outside sources of financing. The Company expects to launch Cuckoo 3.0 Series products in 2024 and has received certain advance payments from customers as of the date of this report. In addition, the Company has been continuously receiving financing support from investors and related parties through the issuances of ordinary shares and credit facilities. Refer to Note 11 and Note 10 for details of the Company’s ordinary shares financing activities and credit facilities. Moreover, the Company has the ability to adjust the pace of its operation expansion and control the operating expenses.

As a result, the Company’s cash flow projections for the period after one year from the date that the consolidated financial statements are issued indicate that the Company’s existing cash and cash equivalents, together with the operating cash flows will be sufficient to cover the liquidity needs that become due within one year after the date that the consolidated financial statements are issued. Management’s plans described above have alleviated the previously identified substantial doubt about the Company’s ability to continue as a going concern. The accompanying consolidated financial statements are prepared in accordance with generally accepted accounting principles applicable to a going concern. However, the Company may need additional capital in the future to fund the continued operations of the Company. There can be no assurance that the Company will be successful in acquiring additional financing, that the Company’s projections of its future working capital needs will prove accurate, or that any additional financing would be sufficient to continue operations in future years.
