REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and

Shareholders of Tantech Holdings, Ltd.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Tantech Holdings, Ltd. and subsidiaries (collectively, the “Company”) as of December 31, 2021 and 2020, and the related consolidated statements of operations and comprehensive income (loss), changes in stockholders’ equity, and cash flows for the years ended December 31, 2021, 2020 and 2019, and the related notes (collectively referred to as the “financial statements”).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for years ended December 31, 2021, 2020 and 2019, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or are required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved especially challenging, subjective, or complex judgments.

Valuation of Electric Vehicle Manufacturing License as of December 31, 2020

The Company has an electric vehicle manufacturing license which has an indefinite life. As of December 31, 2019, the aggregate amount of the indefinite-lived intangible assets was approximately $12.0 million. In 2020, the Company recorded impairment charges relating to the company’s indefinite-lived intangible assets of $12.0 million. As discussed in Note 11 to the consolidated financial statements, the Company tests its indefinite-lived intangible assets for impairment annually and whenever events or circumstances indicate that it is more likely than not that the impairment may have occurred.

F-2

Auditing the Company’s impairment test on Indefinite-lived Intangible Assets was complex due to the significant judgment required in determining the fair value of the reporting unit. In particular, the fair value estimate was sensitive to significant assumptions that require judgment, including the amount and timing of future cash flows (e.g. revenue growth rates) and the weighted average cost of capital (“discount rate”), which are affected by factors such as general market conditions and recent operating performance.

To test the estimated fair value of the Company’s reporting unit, our audit procedures included, among others, evaluating the valuation methodology and the reasonableness of management’s revenue growth rate and gross margin forecasts. We compared the assumptions in the valuation process described above, used by management, to current industry and economic trends, historical Company results, changes to the Company’s business model, regulatory changes, customer base or revenue mix and other relevant factors. We evaluated the Company’s internal and external communications to identify any corroboratory or contrary evidence. We assessed the historical accuracy of management’s estimates and evaluated management’s sensitivity assessment of the subjective assumptions to evaluate the changes in the analysis that would result from changes in these assumptions.

/s/ YCM CPA, Inc.

We have served as the Company’s auditor since 2022.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 2 – Summary of Significant Accounting Policies

Principal of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The consolidated financial statements include the financial statements of Tantech BVI and its subsidiaries (collectively, the “Company”). All significant inter-company balances and transactions are eliminated upon consolidation.

Non-controlling interest

Non-controlling interest represents 30% of the equity interest in Shangchi Automobile and its subsidiary Shenzhen Yimao owned by Zhangjiagang Jinke Chuangtou Co., Ltd., which is not under the Company’s control.

Use of Estimates

In preparing the consolidated financial statements in conformity with US GAAP, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the dates of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting year. Significant items subject to such estimates and assumptions include the fair value estimates used in the useful lives of property and equipment and intangible assets, allowances pertaining to the allowance for doubtful accounts of accounts receivable, advance to suppliers and other receivables, the valuation of inventories, the impairment of long-lived assets, and the realizability of deferred tax assets.

Fair Value of Financial Instruments

The Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurements”, defines fair value, establishes a three-level valuation hierarchy for fair value measurements and enhances disclosure requirements.

The three levels are defined as follows:

Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted market prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data.

Level 3 - inputs to the valuation methodology are unobservable.

Unless otherwise disclosed, the fair value of the Company’s financial instruments including cash, restricted cash, accounts receivable, advances to suppliers, other receivables, accounts payable, customer deposits, accrued expenses, short term bank loans and bank acceptance notes payable approximates their recorded values due to their short-term maturities.

Cash and cash equivalents

For purposes of the statements of cash flows, the Company considers all highly liquid instruments purchased with an original maturity of three months or less and money market accounts to be cash equivalents. All cash balances are in bank accounts in PRC and are not insured by the Federal Deposit Insurance Corporation or other programs.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 2 – Summary of Significant Accounting Policies (continued)

Restricted Cash

For the year ended December 31, 2020, restricted cash represents the cash of $220,109 required deposits as a part of collateral for bank acceptance notes payable and letters of credit. The Company is required to maintain 0% to 100% of the balance of the bank acceptance notes payable in restricted cash to ensure future credit availability. The Company earns interest at a variable rate per month on this restricted cash.

For the year ended December 31, 2021, the Company’s restricted cash represents the cash of $422,832 remains frozen in the bank accounts of one of the Company’s subsidiaries as the result of the ongoing lawsuit filed by Mr. Hengwei Chen to against the Company (see Note 15).

Concentrations of credit risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash, trade accounts receivable and advances to suppliers. All of the Company’s cash is maintained with banks within the People’s Republic of China of which no deposits are covered by insurance. The Company has not experienced any losses in such accounts. A significant portion of the Company’s sales are credit sales which are primarily to customers whose ability to pay is dependent upon the industry economics prevailing in these areas. The Company also makes cash advances to certain suppliers to ensure the stable supply of key raw materials. The Company performs ongoing credit evaluations of its customers and key suppliers to help further reduce credit risk.

Accounts receivable

Accounts receivable are presented at invoiced amount net of an allowance for doubtful accounts. The Company maintains an allowance for doubtful accounts for estimated losses. The Company reviews its accounts receivable on a periodic basis and makes general and specific allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, the Company considers many factors, including the age of the balance, customer’s payment history, its current credit-worthiness and current economic trends. Accounts are written off after efforts at collection prove unsuccessful.

Inventory

The Company values its inventories at the lower of cost, determined on a weighted average basis, or net realizable value. The Company reviews its inventories periodically to determine if any markdown is necessary for potential obsolescence or if a write-down is necessary if the carrying value exceeds net realizable value.

Advances to suppliers

In order to ensure a steady supply of raw materials, the Company is required from time to time to make cash advances when placing its purchase orders. The Company reviews its advances to suppliers on a periodic basis and makes general and specific allowances when there is doubt as to the ability of a supplier to refund an advance or provide supplies to the Company.

Property and Equipment and Construction in Progress

Property and equipment are stated at cost less accumulated depreciation. The cost of an asset comprises its purchase price and any directly attributable costs of bringing the asset to its present working condition and location for its intended use.

F-10

TANTECH HOLDINGS LTD AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 2 – Summary of Significant Accounting Policies (continued)

Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets. The estimated useful lives for significant property and equipment are as follows:

Buildings	20 years
Machinery and equipment	5 - 10 years
Transportation equipment	4 - 5 years
Office equipment	4 - 5 years
Electronic equipment	3 - 5 years

Repairs and maintenance costs are normally charged to earnings in the year in which they are incurred. In situations where it can be clearly demonstrated that the expenditure has resulted in an increase in the future economic benefits expected to be obtained from the use of the asset, the expenditure is capitalized as an additional cost of the asset.

Construction in progress includes direct costs of construction or acquisition of equipment, interest expense associated with the loans used for the construction and design fees incurred. Capitalization of these costs ceases and the construction in progress is transferred to plant and equipment when substantially all the activities necessary to prepare the assets for their intended use are completed. No depreciation is provided until it is completed and ready for its intended use.

Intangible assets

Intangible assets are acquired individually or as part of a group of assets, and are initially recorded at cost. The cost of a group of assets acquired in a transaction is allocated to the individual assets based on their relative fair values. Intangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets with finite useful lives are amortized using a straight-line method over the period of estimated useful life. The estimated useful lives of the Company’s intangible assets are as follows:

	Estimated Useful Life
Licenses and permits	Indefinite
Software	5 - 10 years
Land use right	50 years
Patents	10 years

The Company evaluates intangible assets for impairment whenever events or changes in circumstances indicate that the assets might be impaired.

Long term investments

The Company accounts for investment in equity investees over which it has significant influence but does not own a majority of the equity interest or lack of control using the equity method. For investment in equity investees over which the Company does not have significant influence or the underlying shares the Company invested in are not considered in-substance common stock and have no readily determinable fair value, the cost method accounting is applied.

The Company records the equity method investments at historical cost and subsequently adjusts the carrying amount each period for share of the earnings or losses of the investee and other adjustments required by the equity method of accounting. Dividends received from the equity method investments are recorded as reductions in the cost of such investments. The Company records the cost method investments at historical cost and subsequently record any dividends received from the net accumulated earnings of the investee as income. Dividends received in excess of earnings are considered a return of investment and are recorded as reductions in the cost of the investments.

F-11

TANTECH HOLDINGS LTD AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 2 – Summary of Significant Accounting Policies (continued)

Investment in equity investees are evaluated for impairment when facts or circumstances indicate that the fair value of the investment is less than its carrying value. An impairment is recognized when a decline in fair value is determined to be other-than-temporary. The Company reviews several factors to determine whether a loss is other-than-temporary. These factors include, but are not limited to, the: (i) nature of the investment; (ii) cause and duration of the impairment; (iii) extent to which fair value is less than cost; (iv) financial condition and near term prospects of the investments; and (v) ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.

Impairment of Long-Lived Assets

The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances, such as a significant adverse change to market conditions that will impact the future use of the assets, indicate that the carrying amount of an asset may not be fully recoverable. When these events occur, the Company evaluates the recoverability of long-lived assets by comparing the carrying amount of the assets to the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their fair value. Fair value is generally determined by discounting the cash flows expected to be generated by the assets, when the market prices are not readily available.

Customer Deposits

Customer deposits represent amounts received from customers in advance of shipments relating to the sales of the Company’s products.

Loan Payable to Third Parties

Loan payable to third parties represent amounts the Company borrowed from third parties for working capital purpose. As of December 31, 2021, the balance amounted $7,002,385, the balances are unsecured with interest rate 6% per annum and with one year term from December 17, 2021 to December 16, 2022. If the Company fails to repay the debt, the Company shall pay the third parties for the liquidated damages at the rate of thousandths of the amount in arrears per day, and also compensate the legal costs, execution fees, etc. incurred in realizing the creditor’s rights. As of December 31, 2020, the balance amounted $306,600, the balance is unsecured, interest-free and due upon demand.

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842). The standard requires lessees to recognize lease assets and lease liabilities on the balance sheet and requires expanded disclosures about leasing arrangements. The new standard establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months.

The Company adopted ASC 842 on January 1, 2019 on a modified retrospective basis and elected the practical expedients permitted under the transition guidance, which allows the Company to carryforward the historical lease classification, the assessment on whether a contract is or contains a lease, and the initial direct costs for any leases that exist prior to adoption of the new standard. Leases with an initial term of 12 months or less are not recognized on the balance sheet and the associated lease payments are included in the consolidated statements of comprehensive income (loss) on a straight-line basis over the lease term. The standard did not materially impact our consolidated net earnings and cash flows.

Note 2 – Summary of Significant Accounting Policies (continued)

Revenue Recognition

The Company adopted ASC Topic 606 Revenue from Contracts with Customers (“ASC 606”) on January 1, 2018 using the modified retrospective approach. There is no adjustment to the opening balance of retained earnings at January 1, 2018 since there was no change to the timing and pattern of revenue recognition upon adoption of ASC 606. Under ASC 606, revenue is recognized when control of promised goods or services is transferred to the Company’s customers in an amount of consideration to which an entity expects to be entitled to in exchange for those goods or services. The Company’s revenues are primarily derived from the following sources:

Sales of products: The Company recognizes sales revenue, net of sales taxes and estimated sales returns, at the time the product is delivered to the customer and control is transferred (point of sale).

For the Company’s electric vehicles sales contracts, the Company provides a warranty for 12 months from the products are delivered. The Company determines such product warranty is an assurance-type warranty and is not a separated performance obligation in revenue recognition, because the nature of warranty is to provide assurance that a product will function as expected and in accordance with customer’s specification. The Company estimates the warranty costs when the promised good is delivered to the customer and accrues as warranty liabilities.

Commission income: The Company acts as an agent without assuming the risks and rewards of ownership of the goods and reports the revenue on a net basis. Revenue is recognized based on the completion of the contracted service.

Government manufacturing rebate income: The Company sells electric vehicles in China and is eligible for a government manufacturing rebate on each qualifying electric vehicle sold. The government manufacturing rebates are recognized as part of revenue when sales are finalized, amount of rebates can be reasonably estimated and collection is assured. The collectability of rebates can be assured as long as the sales are deemed qualifying based on the criteria set by the government.

Revenue is reported net of all value added taxes. The Company does not routinely permit customers to return products and historically, customer returns have been immaterial.

Cost of Revenues

Cost of revenues includes cost of raw materials purchased, inbound freight cost, cost of direct labor, depreciation expense and other overhead. Write-down of inventory for lower of cost or net realizable value adjustments is also recorded in cost of revenues.

Shipping and Handling

Shipping and handling costs are expensed as incurred and included in selling expenses.

Subsidy Income

The Company periodically receives various government grants such as “High Technology Projects Subsidy” and “Scientific Research Grant”. There is no guarantee the Company will continue to receive such grants in the future.

Foreign Currency Translation

The Company’s financial information is presented in U.S. dollars. The functional currency of the Company’s subsidiaries in the PRC is the RMB, the currency of the PRC. Any subsidiary transactions, which are denominated in currencies other than RMB, are translated into RMB at the exchange rate quoted by the People’s Bank of China prevailing at the dates of the transactions, and exchange gains and losses are included in the statements of comprehensive income (loss) as foreign currency transaction gain or loss. The consolidated financial statements of the Company have been translated into U.S. dollars in accordance with ASC 830, “Foreign Currency Matters”. The financial information is first prepared in RMB and then is translated into U.S. dollars at period-end exchange rates for assets and liabilities and average exchange rates for revenue and expenses. Capital accounts are translated at their historical exchange rates when the capital transactions occurred. The effects of foreign currency translation adjustments are included as a component of accumulated other comprehensive income in stockholders’ equity. Cash flows from the Company’s operations are calculated based upon the local currencies using the average translation rate. As a result, amounts related to assets and liabilities reported on the statements of cash flows will not necessarily agree with changes in the corresponding balances on the balance sheets.

The following table outlines the currency exchange rates that were used in creating the consolidated financial statements in this report:

	December 31, 2021			December 31, 2020			December 31, 2019
US$: RMB exchange rate	Period End	$	0.1569	Period End	$	0.1533	Period End	$	0.1436
	Average	$	0.1550	Average	$	0.1448	Average	$	0.1448

Research and development costs

Research and development expenses include costs directly attributable to the conduct of research and development projects, including the cost of salaries and other employee benefits, testing expenses, consumable equipment and consulting fees prior to the establishment of technological feasibility. All costs associated with research and development are expensed as incurred.

Comprehensive Income (loss)

Comprehensive income (loss) consists of two components, net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) refers to revenue, expenses, gains and losses that under GAAP are recorded as an element of stockholders’ equity but are excluded from net income (loss). Other comprehensive income (loss) consists of foreign currency translation adjustment from those subsidiaries not using the U.S. dollar as their functional currency.

Income Taxes

The Company’s subsidiaries in China are subject to the income tax laws of the PRC. No taxable income was generated outside the PRC as of December 31, 2021. The Company accounts for income taxes in accordance with ASC 740, “Income Taxes”. ASC 740 requires an asset and liability approach for financial accounting and reporting for income taxes and allows recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or future deductibility is uncertain.

ASC 740-10-25 prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken (or expected to be taken) in a tax return. It also provides guidance on the recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, years open for tax examination, accounting for income taxes in interim periods and income tax disclosures. The statute of limitation on the PRC tax authority’s audit or examination of previously filed tax returns expires three years from the date they were filed. There were no material uncertain tax positions as of December 31, 2021 and 2020.

Note 2 – Summary of Significant Accounting Policies (continued)

Value Added Tax (“VAT”)

The Company is subject to VAT for selling merchandise. The applicable VAT rate is 11% or 13% or 17% (depending on the type of goods involved) for products sold in the PRC. The applicable VAT rate of 17% and 11% decreased to 16% and 10% starting from May 2018, and further decreased to 13% and 9% from April 1, 2019. The amount of VAT liability is determined by applying the applicable tax rate to the invoiced amount of goods sold (output VAT) less VAT paid on purchases made with the relevant supporting invoices (input VAT). Under the commercial practice of the PRC, the Company pays VAT based on tax invoices issued. The tax invoices may be issued subsequent to the date on which revenue is recognized, and there may be a considerable delay between the date on which the revenue is recognized and the date on which the tax invoice is issued. In the event the PRC tax authorities dispute the date on which revenue is recognized for tax purposes, the PRC tax office has the right to assess a penalty based on the amount of taxes which is determined to be late or deficient, with any penalty being expensed in the period when a determination is made by the tax authorities that a penalty is due. During the reporting periods, the Company had no dispute with PRC tax authorities and there was no tax penalty incurred.

Earnings (loss) per Share (“EPS”)

The Company computes earnings (loss) per share (“EPS”) in accordance with ASC 260, “Earnings per Share” (“ASC 260”), and SEC Staff Accounting Bulletin No. 98 (“SAB 98”). ASC 260 requires companies with complex capital structures to present basic and diluted EPS. Basic EPS is measured as net income divided by the weighted average common shares outstanding for the period. Diluted EPS is similar to basic EPS but presents the dilutive effect on a per share basis of potential common shares (e.g., convertible securities, options and warrants) as if they had been converted at the beginning of the periods presented, or issuance date, if later. Potential common shares that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted EPS. As of December 31, 2021 and 2020, the total number of registered and unregistered warrants outstanding both was 6,557,635 (split-adjusted 655,764). For the years ended December 31, 2021, 2020 and 2019, no warrants were included in the diluted income (loss) per share as they would be anti-dilutive.

Statement of Cash Flows

In accordance with ASC 230, “Statement of Cash Flows,” cash flows from the Company’s operations are calculated based upon the local currencies. As a result, amounts related to assets and liabilities reported on the statements of cash flows will not necessarily agree with changes in the corresponding balances on the balance sheets.

Risks and Uncertainties

The operations of the Company are located in the PRC. Accordingly, the Company’s business, financial condition, and results of operations may be influenced by the political, economic, and legal environments in the PRC, in addition to the general state of the PRC economy. The Company’s operating results may be adversely affected by changes in the political and social conditions in the PRC, and by changes in governmental policies with respect to laws and regulations, anti-inflationary measures, currency conversion and remittance abroad, and rates and methods of taxation, among other things.

The Company’s sales, purchases and expense transactions are denominated in RMB, and primarily all of the Company’s assets and liabilities are also denominated in RMB. The RMB is not freely convertible into foreign currencies under the current law. In China, foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People’s Bank of China, the central bank of China. Remittances in currencies other than RMB may require certain supporting documentation in order to affect the remittance.

Note 2 – Summary of Significant Accounting Policies (continued)

The Company does not carry any business interruption insurance, products liability insurance or any other insurance policy except for a limited property insurance policy. As a result, the Company may incur uninsured losses, increasing the possibility that investors would lose their entire investment in the Company.

COVID-19

The Company’s operations were affected by the recent and ongoing outbreak of the coronavirus disease 2019 (COVID-19) which in March 2020, was declared a pandemic by the World Health Organization. The COVID-19 outbreak is causing lockdowns, travel restrictions, and closures of businesses. The Company’s business has been negatively impacted by the COVID-19 coronavirus outbreak to certain extent in fiscal 2020.

From late January 2020 to the middle of February 2020, the Company had to temporarily suspend our manufacturing activities due to government restrictions. During the temporary business closure period, our employees had very limited access to our manufacturing facilities and the shipping companies were not available and as a result, the Company experienced difficulty delivering our products to the customers on a timely basis. In addition, due to the COVID-19 outbreak, some of the customers or suppliers may experience financial distress, delay or default on their payments, reduce the scale of their business, or suffer disruptions in their business due to the outbreak. Any increased difficulty in collecting accounts receivable, delayed raw materials supply, bankruptcy of small and medium businesses, or early termination of agreements due to deterioration in economic conditions could negatively impact our results of operations.

As of the date of this filing, the COVID-19 coronavirus outbreak in China appears to be controlled and most provinces and cities have resumed business activities under the guidance and support of the government. In light of the current situation, the Company believes that the impact of the COVID-19 outbreak on the business is both temporary and limited, and that the revenues have started growing again in fiscal 2021. However, there is still significant uncertainty regarding the possibility of another wave of infections, and the breadth and duration of business disruptions related to COVID-19, which could continue to have material impact to the Company’s operations.

Recent accounting pronouncements

The Company considers the applicability and impact of all accounting standards updates (“ASUs”). Management periodically reviews new accounting standards that are issued.

In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes” (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 will simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company adopted this guidance and this guidance did not have a material impact on the consolidated financial statements.

Note 2 – Summary of Significant Accounting Policies (continued)

In January 2020, the FASB issued ASU 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) (“ASU 2020-01”), which is intended to clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. ASU 2020-01 is effective for the Company beginning January 1, 2021. The Company adopted this guidance and this guidance did not have a material impact on the consolidated financial statements.

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt — Modifications and Extinguishments (Subtopic 470-50), Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (“ASU 2021-04”). ASU 2021-04 provides guidance as to how an issuer should account for a modification of the terms or conditions or an exchange of a freestanding equity-classified written call option (i.e., a warrant) that remains classified after modification or exchange as an exchange of the original instrument for a new instrument. An issuer should measure the effect of a modification or exchange as the difference between the fair value of the modified or exchanged warrant and the fair value of that warrant immediately before modification or exchange and then apply a recognition model that comprises four categories of transactions and the corresponding accounting treatment for each category (equity issuance, debt origination, debt modification, and modifications unrelated to equity issuance and debt origination or modification). ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the guidance provided in ASU 2021-04 prospectively to modifications or exchanges occurring on or after the effective date. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt ASU 2021-04 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The Company adopted this guidance and this guidance did not have a material impact on the consolidated financial statements.

Except for the above-mentioned pronouncements, there are no new recent issued accounting standards that will have material impact on the consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 3 – Variable Interest Entity

Before August 3, 2021, Tantech BVI controls certain entities through a series of agreements known as variable interest agreements (“VIE”).

Wangbo, Shangchi Automobile and its subsidiary, Shenzhen Yimao, are controlled through contractual arrangements in lieu of direct equity ownership by the Company. These agreements include an Exclusive Management Consulting and Technology Agreement, two Equity Pledge Agreements, two Exclusive Call Option Agreements, two Proxy Agreements and two Powers of Attorney (collectively “VIE Agreements”). Pursuant to the above VIE Agreements, Jiamu has the exclusive right to provide Wangbo consulting services related to business operations including technical and management consulting services. All the above contractual agreements obligate Jiamu to absorb a majority of the risk of loss from Wangbo’s activities and entitle Jiamu to receive a majority of their residual returns. In essence, Jiamu has gained effective control over Wangbo. Wangbo owns 51% and Jiyi owns 19% of Shangchi Automobile respectively. A third party owns 30% of Shangchi automobile.

In accordance with accounting standards regarding consolidation of variable interest entities, VIEs are generally entities that lack sufficient equity to finance their activities without additional financial support from other parties or whose equity holders lack adequate decision making ability. The VIEs with which the Company is involved must be evaluated to determine the primary beneficiary of the risks and rewards of the VIE. The primary beneficiary is required to consolidate the VIE for financial reporting purposes. Therefore, the Company believes that Wangbo should be considered as a Variable Interest Entity (“VIE”) under the Statement of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810 “Consolidation”.

Jiamu is deemed to have a controlling financial interest in and be the primary beneficiary of Wangbo because it has both of the following characteristics:

● The power to direct activities at Wangbo that most significantly impact such entity’s economic performance, and

● The obligation to absorb losses of, and the right to receive benefits from Wangbo that could potentially be significant to such entity.

Pursuant to the contractual arrangements with Wangbo, Wangbo pays service fees equal to 95% of its net profit after tax payments to Jiamu. At the same time, Jiamu is obligated to absorb a majority of Wangbo’s losses. Such contractual arrangements are designed so that the operation of Wangbo is for the benefit of Jiamu and ultimately, the Company.

Note 3 – Variable Interest Entity (continued)

Risks associated with the VIE structure

The Company believes that the contractual arrangements with its VIE and the VIE’s shareholders are in compliance with PRC laws and regulations and are legally enforceable. However, uncertainties in the PRC legal system could limit the Company’s ability to enforce the contractual arrangements. If the legal structure and contractual arrangements were found to be in violation of PRC laws and regulations, the PRC government could:

● revoke the business and operating licenses of the Company’s PRC subsidiary and VIE;

● discontinue or restrict the operations of any related-party transactions between the Company’s PRC subsidiary and VIE;

● limit the Company’s business expansion in China by way of entering into contractual arrangements;

● impose fines or other requirements with which the Company’s PRC subsidiary and VIE may not be able to comply;

● require the Company or the Company’s PRC subsidiary and VIE to restructure the relevant ownership structure or operations; or

● restrict or prohibit the Company’s use of the proceeds from public offering to finance the Company’s business and operations in China.

The Company’s ability to conduct its business through its VIE may be negatively affected if the PRC government were to carry out of any of the aforementioned actions. As a result, the Company may not be able to consolidate its VIE and its VIE’s subsidiary in its consolidated financial statements as it may lose the ability to exert effective control over the VIE and its shareholders and it may lose the ability to receive economic benefits from the VIE. The Company, however, does not believe such actions would result in the liquidation or dissolution of the Company, its PRC subsidiary and its VIE.

Dismantling VIE structure

On August 3, 2021, the Company completed dismantling its VIE structure and began controlling Wangbo, Shangchi Automobile and its subsidiary, Shenzhen Yimao, through direct equity ownership instead of a series of contractual arrangements.

Prior to August 3, 2021, the Company’s wholly owned subsidiary - Jiamu effectively controlled and was entitled to the economic benefits of the Company’s VIE entity - Wangbo through a series of contractual arrangement, which were designed to provide Jiamu with certain powers, rights, and obligations to Wangbo, as set forth under the VIE Agreements. Accordingly, Jiamu was regarded as the primary beneficiary of Wangbo for accounting purposes and consolidated the financial results of the Wangbo and its subsidiaries under the ASC810 “Consolidation.”

On July 28, 2021, Jiamu, Wangbo and the nominal shareholders of Wangbo signed Terminational Agreement to terminate the VIE agreement and the nominal shareholders who previously owns 100% equity interest of Wangbo transferred all their equity interest in Wangbo to Jiamu for a nominal consideration (the “Dismantlement Transaction”). As a result, Wangbo becomes a wholly owned subsidiary of Jiamu. The Dismantlement Transaction was completed on August 3, 2022. Since Wangbo is effective controlled by the Company through our wholly owned subsidiary Jiamu before and after the Dismantlement Transaction, the Dismantlement Transaction is considered a reorganization under common control and the consolidation of Wangbo and its subsidiaries has been accounted for at historical cost in accordance with Accounting Standards Codification (“ASC”) 805-50-30-5.

After the VIE was dismantled, the Company owns 100% of equity interests in Wangbo. Wangbo and Jiyi keep owning 51% and 19% of Shangchi Automobile respectively. A third party keeps owning 30% of Shangchi Automobile.

Note 4 — Liquidity

In fiscal 2021, the Company had a significantly growth in bamboo related products which generated revenue of $53.4 million from its consumer product segment. In addition, two subsidiaries focus on developing and manufacturing of smart electric sanitation vehicles also generated revenue of $1.9 million from Electric Vehicle (the “EV”) segment.  

However, the Company had incurred approximately $8.1 million research and development costs on its smart electric sanitation vehicles designed to be used in industrial parks and residential communities. The Company also recorded 100% allowance of total $5.8 million manufacturing rebate receivable due to the fact that there is remote possibility to successfully claim the manufacturing rebate under the newly implemented government policy (see Note 8). These costs offset the increase of the revenues and gross profit in fiscal 2021. Therefore, for the year ended December 31, 2021, the Company incurred continuous loss and had negative cash flows from its operations.

In fiscal 2021, the Company successfully completed two equity financings which resulted in net proceeds of $19.4 million. In addition, the Company obtained net proceeds of $9.1 million and $5.6 million from equity financings in November 2020 and September 2017, respectively. As a result, the Company had approximately $43.1 million cash on hand as of December 31, 2021. Although the Company maintains a positive working capital as of December 31, 2021, the future operations of the Company depend on whether or not the Company can successfully collect its accounts receivable and utilize its advances, as well as how the change of government policies affect its EV business.

The Company currently plans to fund its operations mainly through renewal of bank borrowings, additional equity financing and the continuing financial support by its shareholders and its affiliates controlled by its principal shareholder, if necessary, in the near future to ensure sufficient working capital. The Company has implemented a stricter policy on sales to supermarkets and less credible customers and continues to improve its collection efforts on accounts with outstanding balances. The Company is actively working with its customers and suppliers and expects to fully collect outstanding accounts receivables or utilize the rest of prepayment balance in 2022.

The Company plans to fund the EV segment through additional private placement and continued support from the parent company. The principal shareholder of the Company, along with the affiliated entity, Forasen Group, has agreed to provide financial support to the Company whenever necessary.

Based on its current operating plan, management believes that the above-mentioned measures collectively will provide sufficient liquidity for the Company to meet its future liquidity and capital requirements for at least next twelve months from the date of this report.

On September 13, 2013, the Chinese Ministry of Finance, the Chinese Ministry of Science and Technology, the Chinese Ministry of Industry and Information Technology, and the Chinese National Development and Reform Commission issued a joint announcement that in order to promote the development, sale and use of alternative energy vehicles, Chinese government will continue to provide a manufacturing rebate for qualifying alternative energy vehicles sold. The government manufacturing rebates are typically provided to eligible alternative energy automobile manufacturers after sales are finalized and paperwork regarding the eligible mileages is submitted. Based on the criteria, Shangchi Automobile (formerly known as Suzhou E-Motors) was eligible for government manufacturing rebates and had $5,755,237 as manufacturing rebate receivable as of December 31, 2020.

In 2021, the Chinese Ministry of Finance, the Chinese Ministry of Science and Technology, the Chinese Ministry of Industry and Information Technology, and the Chinese National Development and Reform Commission implemented a new policy which requires the minimum number of alternative energy vehicles for manufacturing rebate application shall be 10,000 for passenger vehicles and 1,000 for commercial use vehicles.

The Company determined that there is remote possibility to successfully claim the manufacturing rebate under the newly implemented policy. As a result, the Company recorded 100% allowance against the manufacturing rebate receivable as of December 31, 2021.

Note 11 – Leases

Effective January 1, 2019, the Company adopted ASC 842, the new lease accounting standard using a modified retrospective transition method which allowed the Company not to recast comparative periods presented in its consolidated financial statements. In addition, the Company elected the package of practical expedients, which allowed the Company to not reassess whether any existing contracts contain a lease, to not reassess historical lease classification as operating or finance leases, and to not reassess initial direct costs. The Company has not elected the practical expedient to use hindsight to determine the lease term for its leases at transition. The Company combines the lease and non-lease components in determining the ROU assets and related lease obligation. Adoption of this standard resulted in the recording of operating lease ROU assets and corresponding operating lease liabilities as disclosed below and had no impact on retained earnings as of December 31, 2021. ROU assets and related lease obligations are recognized at commencement date based on the present value of remaining lease payments over the lease term.

Note 18 – Long Term Investments

On January 10, 2018, the Company invested approximately $18.8 million (or RMB 120 million) to acquire 18% equity interest in Libo Haokun Stone Co., Ltd. (“Libo Haokun”). Libo Haokun holds a government-issued permit and has the exclusive right to mine a 0.11-square-kilometer marble quarry in the central area of Guizhou province, China. Libo Haokun obtained the permit to mine the quarry from the local government in September 2016. The permit was renewed in July 2020 and is further renewable by July 2023.

On November 29, 2019, the Company entered into an investment agreement (the “Investment Agreement”) with Jingning Zhonggang Mining Co., Ltd. (“Jingning Zhonggang”) through Lishui Tantech to acquire 18% of the equity interest of Fuquan Chengwang Mining Co., Ltd. (“Fuquan Chengwang”), a wholly-owned subsidiary of Jingning Zhonggang, at a price of $7.3 million (RMB46.32 million). The consideration equals 18% of RMB257.35 million, the value of the mining right under a permit being renewed by Fuquan Chengwang according to an evaluation report. Fuquan Chengwang is a basalt mining company.

Pursuant to the Investment Agreement, Tantech is obligated to pay the consideration within 30 days after Fuquan Chengwang completes the recording process with the local industrial and commerce administration for transfer of the share ownership. Pursuant to the Investment Agreement, after the transfer of the 18% share ownership, if the value of Fuquan Chengwang is lower than RMB257.35 million according to the financial statements audited by an accounting firm approved by the Tantech, Jingning Zhonggang will be obligated to refund to Tantech the overpaid amount. The payment could be in the form of cash, shares, or other assets with the same value, as selected by Tantech.

After a series of transactions and reorganization, as of December 31, 2019, the Company and Jingning Zhonggang owns 18% and 82% of Libo Haokun, respectively, through Jingning Meizhongkuang Industry Co., Ltd. (“Jingning Meizhongkuang”). Jingning Meizhongkuang owns 100% of Fuquan Chengwang. The Agreements would enable Tantech to indirectly hold a 18% stake in Fuquan Chengwang through holding 18% of the equity interest of Jingning Meizhongkuang.

On April 3, 2020, Lishui Ansheng Energy Technology Co., a third party, signed an investment agreement with Jingning Meizhongkuang to invest in Fuquan Chengwang by paying $7.3 million (RMB 46.5 million) to exchange 18% of the interest of Fuquan Chengwang. After the transaction, the Company’s indirect interest in Fuquan Chengwang was diluted from 18% to 14.76% through holding 18% of the equity interest of Jingning Meizhongkuang.

Fuquan Chengwang received the renewed mining permit in March 2021, and expiration date is March 2024. The mining permit provides it the right to mine a 0.2607-square-kilometer basalt quarry in Fuquan City, Guizhou Province, China.

As the Company did not have significant influence over the equity investees, the investments were accounted for using the cost method. For the year ended December 31, 2021, 2020 and 2019, the Company did not recognize any impairment losses for the long-term investments.

Note 20 – Segment Information

The Company uses the “management approach” in determining reportable operating 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. Due to business strategic changes, the Company merged consumer products segment and trading segment. As a result, the Company has determined that it has two operating segments as defined by ASC 280, “Segment Reporting”: consumer products and electric vehicles (“EV”). Consumer products segment manufactures, sell and trade Charcoal Doctor branded products and BBQ charcoal in China. The EV segment was acquired in July 2017. Management, including the chief operating decision maker, reviews operation results of consumer products and electric vehicles separately.

Share Consolidation

On February 24, 2022, the Company’s Board approved a share consolidation of the Company’s common shares at the ratio of one-for-ten reverse split with the effective date of February 25, 2022. The objective of the share consolidation is to enable the company to regain compliance with NASDAQ Marketplace Rule 5550(a)(2) and maintain its listing on Nasdaq.

As a result of the share consolidation, each 10 common shares outstanding automatically combines and converts to one issued and outstanding common share without any action on the part of the shareholder. The share consolidation reduces the number of common shares issued and outstanding from 63,994,606 to 6,399,460. The authorized number of common shares will be reduced by the same one-for-ten ratio from 600 million to 60 million.

Public Offering

On March 18, 2022, the Company closed a public offering of 20,000,000 common shares and prefunded warrants to purchase common shares at a price of $0.50 per common share (the “Offering”). The gross proceeds to the Company were approximately $10.0 million, before deducting underwriting discounts and commissions and other estimated expenses payable by the Company. In addition, the Company granted the underwriters a 45-day option to purchase an additional 15% of common shares at the public offering price to cover over-allotments, if any (the “Over-allotment Option”). On March 22, 2022, the underwriter of the Offering had exercised its Over-allotment Option to purchase an additional 2,880,000 common shares at a price of $0.50 per common share. Total gross proceeds to the Company from the Offering, including the proceeds received from the prior closing and the exercise of the Over-allotment Option, were approximately $11.4 million, before deducting underwriting discounts, commissions, and other offering expenses payable by the Company.

NASDAQ Notice

On April 28, 2022 and May 18, 2022, the Company received notification letters (the “Notice”) from NASDAQ advising the Company that for 30 consecutive business days preceding the date of the Notice, the bid price of the Company’s common shares had closed below the $1.00 per share minimum required for continued listing on The NASDAQ Capital Market pursuant to the Minimum Bid Price Rule. The Company was provided until November 14, 2022 to regain compliance with the Minimum Bid Price Rule.

Incorporation of New Entity

Summary of significant accounting policies

Summary of significant accounting policies

Note 2 – Summary of Significant Accounting Policies

Principal of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The consolidated financial statements include the financial statements of Tantech BVI and its subsidiaries (collectively, the “Company”). All significant inter-company balances and transactions are eliminated upon consolidation.

Non-controlling interest

Non-controlling interest represents 30% of the equity interest in Shangchi Automobile and its subsidiary Shenzhen Yimao owned by Zhangjiagang Jinke Chuangtou Co., Ltd., which is not under the Company’s control.

Use of Estimates

In preparing the consolidated financial statements in conformity with US GAAP, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the dates of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting year. Significant items subject to such estimates and assumptions include the fair value estimates used in the useful lives of property and equipment and intangible assets, allowances pertaining to the allowance for doubtful accounts of accounts receivable, advance to suppliers and other receivables, the valuation of inventories, the impairment of long-lived assets, and the realizability of deferred tax assets.

Fair Value of Financial Instruments

The Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurements”, defines fair value, establishes a three-level valuation hierarchy for fair value measurements and enhances disclosure requirements.

The three levels are defined as follows:

Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted market prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data.

Level 3 - inputs to the valuation methodology are unobservable.

Unless otherwise disclosed, the fair value of the Company’s financial instruments including cash, restricted cash, accounts receivable, advances to suppliers, other receivables, accounts payable, customer deposits, accrued expenses, short term bank loans and bank acceptance notes payable approximates their recorded values due to their short-term maturities.

Cash and cash equivalents

For purposes of the statements of cash flows, the Company considers all highly liquid instruments purchased with an original maturity of three months or less and money market accounts to be cash equivalents. All cash balances are in bank accounts in PRC and are not insured by the Federal Deposit Insurance Corporation or other programs.

Note 2 – Summary of Significant Accounting Policies (continued)

Restricted Cash

For the year ended December 31, 2020, restricted cash represents the cash of $220,109 required deposits as a part of collateral for bank acceptance notes payable and letters of credit. The Company is required to maintain 0% to 100% of the balance of the bank acceptance notes payable in restricted cash to ensure future credit availability. The Company earns interest at a variable rate per month on this restricted cash.

For the year ended December 31, 2021, the Company’s restricted cash represents the cash of $422,832 remains frozen in the bank accounts of one of the Company’s subsidiaries as the result of the ongoing lawsuit filed by Mr. Hengwei Chen to against the Company (see Note 15).

Concentrations of credit risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash, trade accounts receivable and advances to suppliers. All of the Company’s cash is maintained with banks within the People’s Republic of China of which no deposits are covered by insurance. The Company has not experienced any losses in such accounts. A significant portion of the Company’s sales are credit sales which are primarily to customers whose ability to pay is dependent upon the industry economics prevailing in these areas. The Company also makes cash advances to certain suppliers to ensure the stable supply of key raw materials. The Company performs ongoing credit evaluations of its customers and key suppliers to help further reduce credit risk.

Accounts receivable

Accounts receivable are presented at invoiced amount net of an allowance for doubtful accounts. The Company maintains an allowance for doubtful accounts for estimated losses. The Company reviews its accounts receivable on a periodic basis and makes general and specific allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, the Company considers many factors, including the age of the balance, customer’s payment history, its current credit-worthiness and current economic trends. Accounts are written off after efforts at collection prove unsuccessful.

Inventory

The Company values its inventories at the lower of cost, determined on a weighted average basis, or net realizable value. The Company reviews its inventories periodically to determine if any markdown is necessary for potential obsolescence or if a write-down is necessary if the carrying value exceeds net realizable value.

Advances to suppliers

In order to ensure a steady supply of raw materials, the Company is required from time to time to make cash advances when placing its purchase orders. The Company reviews its advances to suppliers on a periodic basis and makes general and specific allowances when there is doubt as to the ability of a supplier to refund an advance or provide supplies to the Company.

Property and Equipment and Construction in Progress

Property and equipment are stated at cost less accumulated depreciation. The cost of an asset comprises its purchase price and any directly attributable costs of bringing the asset to its present working condition and location for its intended use.

Note 2 – Summary of Significant Accounting Policies (continued)

Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets. The estimated useful lives for significant property and equipment are as follows:

Buildings	20 years
Machinery and equipment	5 - 10 years
Transportation equipment	4 - 5 years
Office equipment	4 - 5 years
Electronic equipment	3 - 5 years

Repairs and maintenance costs are normally charged to earnings in the year in which they are incurred. In situations where it can be clearly demonstrated that the expenditure has resulted in an increase in the future economic benefits expected to be obtained from the use of the asset, the expenditure is capitalized as an additional cost of the asset.

Construction in progress includes direct costs of construction or acquisition of equipment, interest expense associated with the loans used for the construction and design fees incurred. Capitalization of these costs ceases and the construction in progress is transferred to plant and equipment when substantially all the activities necessary to prepare the assets for their intended use are completed. No depreciation is provided until it is completed and ready for its intended use.

Intangible assets

Intangible assets are acquired individually or as part of a group of assets, and are initially recorded at cost. The cost of a group of assets acquired in a transaction is allocated to the individual assets based on their relative fair values. Intangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets with finite useful lives are amortized using a straight-line method over the period of estimated useful life. The estimated useful lives of the Company’s intangible assets are as follows:

	Estimated Useful Life
Licenses and permits	Indefinite
Software	5 - 10 years
Land use right	50 years
Patents	10 years

The Company evaluates intangible assets for impairment whenever events or changes in circumstances indicate that the assets might be impaired.

Long term investments

The Company accounts for investment in equity investees over which it has significant influence but does not own a majority of the equity interest or lack of control using the equity method. For investment in equity investees over which the Company does not have significant influence or the underlying shares the Company invested in are not considered in-substance common stock and have no readily determinable fair value, the cost method accounting is applied.

The Company records the equity method investments at historical cost and subsequently adjusts the carrying amount each period for share of the earnings or losses of the investee and other adjustments required by the equity method of accounting. Dividends received from the equity method investments are recorded as reductions in the cost of such investments. The Company records the cost method investments at historical cost and subsequently record any dividends received from the net accumulated earnings of the investee as income. Dividends received in excess of earnings are considered a return of investment and are recorded as reductions in the cost of the investments.

Note 2 – Summary of Significant Accounting Policies (continued)

Investment in equity investees are evaluated for impairment when facts or circumstances indicate that the fair value of the investment is less than its carrying value. An impairment is recognized when a decline in fair value is determined to be other-than-temporary. The Company reviews several factors to determine whether a loss is other-than-temporary. These factors include, but are not limited to, the: (i) nature of the investment; (ii) cause and duration of the impairment; (iii) extent to which fair value is less than cost; (iv) financial condition and near term prospects of the investments; and (v) ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.

Impairment of Long-Lived Assets

The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances, such as a significant adverse change to market conditions that will impact the future use of the assets, indicate that the carrying amount of an asset may not be fully recoverable. When these events occur, the Company evaluates the recoverability of long-lived assets by comparing the carrying amount of the assets to the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their fair value. Fair value is generally determined by discounting the cash flows expected to be generated by the assets, when the market prices are not readily available.

Customer Deposits

Customer deposits represent amounts received from customers in advance of shipments relating to the sales of the Company’s products.

Loan Payable to Third Parties

Loan payable to third parties represent amounts the Company borrowed from third parties for working capital purpose. As of December 31, 2021, the balance amounted $7,002,385, the balances are unsecured with interest rate 6% per annum and with one year term from December 17, 2021 to December 16, 2022. If the Company fails to repay the debt, the Company shall pay the third parties for the liquidated damages at the rate of thousandths of the amount in arrears per day, and also compensate the legal costs, execution fees, etc. incurred in realizing the creditor’s rights. As of December 31, 2020, the balance amounted $306,600, the balance is unsecured, interest-free and due upon demand.

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842). The standard requires lessees to recognize lease assets and lease liabilities on the balance sheet and requires expanded disclosures about leasing arrangements. The new standard establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months.

The Company adopted ASC 842 on January 1, 2019 on a modified retrospective basis and elected the practical expedients permitted under the transition guidance, which allows the Company to carryforward the historical lease classification, the assessment on whether a contract is or contains a lease, and the initial direct costs for any leases that exist prior to adoption of the new standard. Leases with an initial term of 12 months or less are not recognized on the balance sheet and the associated lease payments are included in the consolidated statements of comprehensive income (loss) on a straight-line basis over the lease term. The standard did not materially impact our consolidated net earnings and cash flows.

Note 2 – Summary of Significant Accounting Policies (continued)

Revenue Recognition

The Company adopted ASC Topic 606 Revenue from Contracts with Customers (“ASC 606”) on January 1, 2018 using the modified retrospective approach. There is no adjustment to the opening balance of retained earnings at January 1, 2018 since there was no change to the timing and pattern of revenue recognition upon adoption of ASC 606. Under ASC 606, revenue is recognized when control of promised goods or services is transferred to the Company’s customers in an amount of consideration to which an entity expects to be entitled to in exchange for those goods or services. The Company’s revenues are primarily derived from the following sources:

Sales of products: The Company recognizes sales revenue, net of sales taxes and estimated sales returns, at the time the product is delivered to the customer and control is transferred (point of sale).

For the Company’s electric vehicles sales contracts, the Company provides a warranty for 12 months from the products are delivered. The Company determines such product warranty is an assurance-type warranty and is not a separated performance obligation in revenue recognition, because the nature of warranty is to provide assurance that a product will function as expected and in accordance with customer’s specification. The Company estimates the warranty costs when the promised good is delivered to the customer and accrues as warranty liabilities.

Commission income: The Company acts as an agent without assuming the risks and rewards of ownership of the goods and reports the revenue on a net basis. Revenue is recognized based on the completion of the contracted service.

Government manufacturing rebate income: The Company sells electric vehicles in China and is eligible for a government manufacturing rebate on each qualifying electric vehicle sold. The government manufacturing rebates are recognized as part of revenue when sales are finalized, amount of rebates can be reasonably estimated and collection is assured. The collectability of rebates can be assured as long as the sales are deemed qualifying based on the criteria set by the government.

Revenue is reported net of all value added taxes. The Company does not routinely permit customers to return products and historically, customer returns have been immaterial.

Cost of Revenues

Cost of revenues includes cost of raw materials purchased, inbound freight cost, cost of direct labor, depreciation expense and other overhead. Write-down of inventory for lower of cost or net realizable value adjustments is also recorded in cost of revenues.

Shipping and Handling

Shipping and handling costs are expensed as incurred and included in selling expenses.

Subsidy Income

The Company periodically receives various government grants such as “High Technology Projects Subsidy” and “Scientific Research Grant”. There is no guarantee the Company will continue to receive such grants in the future.

Note 2 – Summary of Significant Accounting Policies (continued)

Foreign Currency Translation

The Company’s financial information is presented in U.S. dollars. The functional currency of the Company’s subsidiaries in the PRC is the RMB, the currency of the PRC. Any subsidiary transactions, which are denominated in currencies other than RMB, are translated into RMB at the exchange rate quoted by the People’s Bank of China prevailing at the dates of the transactions, and exchange gains and losses are included in the statements of comprehensive income (loss) as foreign currency transaction gain or loss. The consolidated financial statements of the Company have been translated into U.S. dollars in accordance with ASC 830, “Foreign Currency Matters”. The financial information is first prepared in RMB and then is translated into U.S. dollars at period-end exchange rates for assets and liabilities and average exchange rates for revenue and expenses. Capital accounts are translated at their historical exchange rates when the capital transactions occurred. The effects of foreign currency translation adjustments are included as a component of accumulated other comprehensive income in stockholders’ equity. Cash flows from the Company’s operations are calculated based upon the local currencies using the average translation rate. As a result, amounts related to assets and liabilities reported on the statements of cash flows will not necessarily agree with changes in the corresponding balances on the balance sheets.

The following table outlines the currency exchange rates that were used in creating the consolidated financial statements in this report:

	December 31, 2021			December 31, 2020			December 31, 2019
US$: RMB exchange rate	Period End	$	0.1569	Period End	$	0.1533	Period End	$	0.1436
	Average	$	0.1550	Average	$	0.1448	Average	$	0.1448

Research and development costs

Research and development expenses include costs directly attributable to the conduct of research and development projects, including the cost of salaries and other employee benefits, testing expenses, consumable equipment and consulting fees prior to the establishment of technological feasibility. All costs associated with research and development are expensed as incurred.

Comprehensive Income (loss)

Comprehensive income (loss) consists of two components, net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) refers to revenue, expenses, gains and losses that under GAAP are recorded as an element of stockholders’ equity but are excluded from net income (loss). Other comprehensive income (loss) consists of foreign currency translation adjustment from those subsidiaries not using the U.S. dollar as their functional currency.

Income Taxes

The Company’s subsidiaries in China are subject to the income tax laws of the PRC. No taxable income was generated outside the PRC as of December 31, 2021. The Company accounts for income taxes in accordance with ASC 740, “Income Taxes”. ASC 740 requires an asset and liability approach for financial accounting and reporting for income taxes and allows recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or future deductibility is uncertain.

ASC 740-10-25 prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken (or expected to be taken) in a tax return. It also provides guidance on the recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, years open for tax examination, accounting for income taxes in interim periods and income tax disclosures. The statute of limitation on the PRC tax authority’s audit or examination of previously filed tax returns expires three years from the date they were filed. There were no material uncertain tax positions as of December 31, 2021 and 2020.

Note 2 – Summary of Significant Accounting Policies (continued)

Value Added Tax (“VAT”)

The Company is subject to VAT for selling merchandise. The applicable VAT rate is 11% or 13% or 17% (depending on the type of goods involved) for products sold in the PRC. The applicable VAT rate of 17% and 11% decreased to 16% and 10% starting from May 2018, and further decreased to 13% and 9% from April 1, 2019. The amount of VAT liability is determined by applying the applicable tax rate to the invoiced amount of goods sold (output VAT) less VAT paid on purchases made with the relevant supporting invoices (input VAT). Under the commercial practice of the PRC, the Company pays VAT based on tax invoices issued. The tax invoices may be issued subsequent to the date on which revenue is recognized, and there may be a considerable delay between the date on which the revenue is recognized and the date on which the tax invoice is issued. In the event the PRC tax authorities dispute the date on which revenue is recognized for tax purposes, the PRC tax office has the right to assess a penalty based on the amount of taxes which is determined to be late or deficient, with any penalty being expensed in the period when a determination is made by the tax authorities that a penalty is due. During the reporting periods, the Company had no dispute with PRC tax authorities and there was no tax penalty incurred.

Earnings (loss) per Share (“EPS”)

The Company computes earnings (loss) per share (“EPS”) in accordance with ASC 260, “Earnings per Share” (“ASC 260”), and SEC Staff Accounting Bulletin No. 98 (“SAB 98”). ASC 260 requires companies with complex capital structures to present basic and diluted EPS. Basic EPS is measured as net income divided by the weighted average common shares outstanding for the period. Diluted EPS is similar to basic EPS but presents the dilutive effect on a per share basis of potential common shares (e.g., convertible securities, options and warrants) as if they had been converted at the beginning of the periods presented, or issuance date, if later. Potential common shares that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted EPS. As of December 31, 2021 and 2020, the total number of registered and unregistered warrants outstanding both was 6,557,635 (split-adjusted 655,764). For the years ended December 31, 2021, 2020 and 2019, no warrants were included in the diluted income (loss) per share as they would be anti-dilutive.

Statement of Cash Flows

In accordance with ASC 230, “Statement of Cash Flows,” cash flows from the Company’s operations are calculated based upon the local currencies. As a result, amounts related to assets and liabilities reported on the statements of cash flows will not necessarily agree with changes in the corresponding balances on the balance sheets.

Risks and Uncertainties

The operations of the Company are located in the PRC. Accordingly, the Company’s business, financial condition, and results of operations may be influenced by the political, economic, and legal environments in the PRC, in addition to the general state of the PRC economy. The Company’s operating results may be adversely affected by changes in the political and social conditions in the PRC, and by changes in governmental policies with respect to laws and regulations, anti-inflationary measures, currency conversion and remittance abroad, and rates and methods of taxation, among other things.

The Company’s sales, purchases and expense transactions are denominated in RMB, and primarily all of the Company’s assets and liabilities are also denominated in RMB. The RMB is not freely convertible into foreign currencies under the current law. In China, foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People’s Bank of China, the central bank of China. Remittances in currencies other than RMB may require certain supporting documentation in order to affect the remittance.

Note 2 – Summary of Significant Accounting Policies (continued)

The Company does not carry any business interruption insurance, products liability insurance or any other insurance policy except for a limited property insurance policy. As a result, the Company may incur uninsured losses, increasing the possibility that investors would lose their entire investment in the Company.

COVID-19

The Company’s operations were affected by the recent and ongoing outbreak of the coronavirus disease 2019 (COVID-19) which in March 2020, was declared a pandemic by the World Health Organization. The COVID-19 outbreak is causing lockdowns, travel restrictions, and closures of businesses. The Company’s business has been negatively impacted by the COVID-19 coronavirus outbreak to certain extent in fiscal 2020.

From late January 2020 to the middle of February 2020, the Company had to temporarily suspend our manufacturing activities due to government restrictions. During the temporary business closure period, our employees had very limited access to our manufacturing facilities and the shipping companies were not available and as a result, the Company experienced difficulty delivering our products to the customers on a timely basis. In addition, due to the COVID-19 outbreak, some of the customers or suppliers may experience financial distress, delay or default on their payments, reduce the scale of their business, or suffer disruptions in their business due to the outbreak. Any increased difficulty in collecting accounts receivable, delayed raw materials supply, bankruptcy of small and medium businesses, or early termination of agreements due to deterioration in economic conditions could negatively impact our results of operations.

As of the date of this filing, the COVID-19 coronavirus outbreak in China appears to be controlled and most provinces and cities have resumed business activities under the guidance and support of the government. In light of the current situation, the Company believes that the impact of the COVID-19 outbreak on the business is both temporary and limited, and that the revenues have started growing again in fiscal 2021. However, there is still significant uncertainty regarding the possibility of another wave of infections, and the breadth and duration of business disruptions related to COVID-19, which could continue to have material impact to the Company’s operations.

Recent accounting pronouncements

The Company considers the applicability and impact of all accounting standards updates (“ASUs”). Management periodically reviews new accounting standards that are issued.

In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes” (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 will simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company adopted this guidance and this guidance did not have a material impact on the consolidated financial statements.

Note 2 – Summary of Significant Accounting Policies (continued)

In January 2020, the FASB issued ASU 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) (“ASU 2020-01”), which is intended to clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. ASU 2020-01 is effective for the Company beginning January 1, 2021. The Company adopted this guidance and this guidance did not have a material impact on the consolidated financial statements.

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt — Modifications and Extinguishments (Subtopic 470-50), Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (“ASU 2021-04”). ASU 2021-04 provides guidance as to how an issuer should account for a modification of the terms or conditions or an exchange of a freestanding equity-classified written call option (i.e., a warrant) that remains classified after modification or exchange as an exchange of the original instrument for a new instrument. An issuer should measure the effect of a modification or exchange as the difference between the fair value of the modified or exchanged warrant and the fair value of that warrant immediately before modification or exchange and then apply a recognition model that comprises four categories of transactions and the corresponding accounting treatment for each category (equity issuance, debt origination, debt modification, and modifications unrelated to equity issuance and debt origination or modification). ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the guidance provided in ASU 2021-04 prospectively to modifications or exchanges occurring on or after the effective date. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt ASU 2021-04 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The Company adopted this guidance and this guidance did not have a material impact on the consolidated financial statements.

Except for the above-mentioned pronouncements, there are no new recent issued accounting standards that will have material impact on the consolidated financial statements.

Variable Interest Entity

12 Months Ended

Dec. 31, 2021

Variable Interest Entity

Variable Interest Entity

Note 3 – Variable Interest Entity

Before August 3, 2021, Tantech BVI controls certain entities through a series of agreements known as variable interest agreements (“VIE”).

Wangbo, Shangchi Automobile and its subsidiary, Shenzhen Yimao, are controlled through contractual arrangements in lieu of direct equity ownership by the Company. These agreements include an Exclusive Management Consulting and Technology Agreement, two Equity Pledge Agreements, two Exclusive Call Option Agreements, two Proxy Agreements and two Powers of Attorney (collectively “VIE Agreements”). Pursuant to the above VIE Agreements, Jiamu has the exclusive right to provide Wangbo consulting services related to business operations including technical and management consulting services. All the above contractual agreements obligate Jiamu to absorb a majority of the risk of loss from Wangbo’s activities and entitle Jiamu to receive a majority of their residual returns. In essence, Jiamu has gained effective control over Wangbo. Wangbo owns 51% and Jiyi owns 19% of Shangchi Automobile respectively. A third party owns 30% of Shangchi automobile.

In accordance with accounting standards regarding consolidation of variable interest entities, VIEs are generally entities that lack sufficient equity to finance their activities without additional financial support from other parties or whose equity holders lack adequate decision making ability. The VIEs with which the Company is involved must be evaluated to determine the primary beneficiary of the risks and rewards of the VIE. The primary beneficiary is required to consolidate the VIE for financial reporting purposes. Therefore, the Company believes that Wangbo should be considered as a Variable Interest Entity (“VIE”) under the Statement of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810 “Consolidation”.

Jiamu is deemed to have a controlling financial interest in and be the primary beneficiary of Wangbo because it has both of the following characteristics:

● The power to direct activities at Wangbo that most significantly impact such entity’s economic performance, and

● The obligation to absorb losses of, and the right to receive benefits from Wangbo that could potentially be significant to such entity.

Pursuant to the contractual arrangements with Wangbo, Wangbo pays service fees equal to 95% of its net profit after tax payments to Jiamu. At the same time, Jiamu is obligated to absorb a majority of Wangbo’s losses. Such contractual arrangements are designed so that the operation of Wangbo is for the benefit of Jiamu and ultimately, the Company.

Note 3 – Variable Interest Entity (continued)

Risks associated with the VIE structure

The Company believes that the contractual arrangements with its VIE and the VIE’s shareholders are in compliance with PRC laws and regulations and are legally enforceable. However, uncertainties in the PRC legal system could limit the Company’s ability to enforce the contractual arrangements. If the legal structure and contractual arrangements were found to be in violation of PRC laws and regulations, the PRC government could:

● revoke the business and operating licenses of the Company’s PRC subsidiary and VIE;

● discontinue or restrict the operations of any related-party transactions between the Company’s PRC subsidiary and VIE;

● limit the Company’s business expansion in China by way of entering into contractual arrangements;

● impose fines or other requirements with which the Company’s PRC subsidiary and VIE may not be able to comply;

● require the Company or the Company’s PRC subsidiary and VIE to restructure the relevant ownership structure or operations; or

● restrict or prohibit the Company’s use of the proceeds from public offering to finance the Company’s business and operations in China.

The Company’s ability to conduct its business through its VIE may be negatively affected if the PRC government were to carry out of any of the aforementioned actions. As a result, the Company may not be able to consolidate its VIE and its VIE’s subsidiary in its consolidated financial statements as it may lose the ability to exert effective control over the VIE and its shareholders and it may lose the ability to receive economic benefits from the VIE. The Company, however, does not believe such actions would result in the liquidation or dissolution of the Company, its PRC subsidiary and its VIE.

Dismantling VIE structure

On August 3, 2021, the Company completed dismantling its VIE structure and began controlling Wangbo, Shangchi Automobile and its subsidiary, Shenzhen Yimao, through direct equity ownership instead of a series of contractual arrangements.

Prior to August 3, 2021, the Company’s wholly owned subsidiary - Jiamu effectively controlled and was entitled to the economic benefits of the Company’s VIE entity - Wangbo through a series of contractual arrangement, which were designed to provide Jiamu with certain powers, rights, and obligations to Wangbo, as set forth under the VIE Agreements. Accordingly, Jiamu was regarded as the primary beneficiary of Wangbo for accounting purposes and consolidated the financial results of the Wangbo and its subsidiaries under the ASC810 “Consolidation.”

On July 28, 2021, Jiamu, Wangbo and the nominal shareholders of Wangbo signed Terminational Agreement to terminate the VIE agreement and the nominal shareholders who previously owns 100% equity interest of Wangbo transferred all their equity interest in Wangbo to Jiamu for a nominal consideration (the “Dismantlement Transaction”). As a result, Wangbo becomes a wholly owned subsidiary of Jiamu. The Dismantlement Transaction was completed on August 3, 2022. Since Wangbo is effective controlled by the Company through our wholly owned subsidiary Jiamu before and after the Dismantlement Transaction, the Dismantlement Transaction is considered a reorganization under common control and the consolidation of Wangbo and its subsidiaries has been accounted for at historical cost in accordance with Accounting Standards Codification (“ASC”) 805-50-30-5.

After the VIE was dismantled, the Company owns 100% of equity interests in Wangbo. Wangbo and Jiyi keep owning 51% and 19% of Shangchi Automobile respectively. A third party keeps owning 30% of Shangchi Automobile.

Note 4 — Liquidity

In fiscal 2021, the Company had a significantly growth in bamboo related products which generated revenue of $53.4 million from its consumer product segment. In addition, two subsidiaries focus on developing and manufacturing of smart electric sanitation vehicles also generated revenue of $1.9 million from Electric Vehicle (the “EV”) segment.  

However, the Company had incurred approximately $8.1 million research and development costs on its smart electric sanitation vehicles designed to be used in industrial parks and residential communities. The Company also recorded 100% allowance of total $5.8 million manufacturing rebate receivable due to the fact that there is remote possibility to successfully claim the manufacturing rebate under the newly implemented government policy (see Note 8). These costs offset the increase of the revenues and gross profit in fiscal 2021. Therefore, for the year ended December 31, 2021, the Company incurred continuous loss and had negative cash flows from its operations.

In fiscal 2021, the Company successfully completed two equity financings which resulted in net proceeds of $19.4 million. In addition, the Company obtained net proceeds of $9.1 million and $5.6 million from equity financings in November 2020 and September 2017, respectively. As a result, the Company had approximately $43.1 million cash on hand as of December 31, 2021. Although the Company maintains a positive working capital as of December 31, 2021, the future operations of the Company depend on whether or not the Company can successfully collect its accounts receivable and utilize its advances, as well as how the change of government policies affect its EV business.

The Company currently plans to fund its operations mainly through renewal of bank borrowings, additional equity financing and the continuing financial support by its shareholders and its affiliates controlled by its principal shareholder, if necessary, in the near future to ensure sufficient working capital. The Company has implemented a stricter policy on sales to supermarkets and less credible customers and continues to improve its collection efforts on accounts with outstanding balances. The Company is actively working with its customers and suppliers and expects to fully collect outstanding accounts receivables or utilize the rest of prepayment balance in 2022.

The Company plans to fund the EV segment through additional private placement and continued support from the parent company. The principal shareholder of the Company, along with the affiliated entity, Forasen Group, has agreed to provide financial support to the Company whenever necessary.

Based on its current operating plan, management believes that the above-mentioned measures collectively will provide sufficient liquidity for the Company to meet its future liquidity and capital requirements for at least next twelve months from the date of this report.

On September 13, 2013, the Chinese Ministry of Finance, the Chinese Ministry of Science and Technology, the Chinese Ministry of Industry and Information Technology, and the Chinese National Development and Reform Commission issued a joint announcement that in order to promote the development, sale and use of alternative energy vehicles, Chinese government will continue to provide a manufacturing rebate for qualifying alternative energy vehicles sold. The government manufacturing rebates are typically provided to eligible alternative energy automobile manufacturers after sales are finalized and paperwork regarding the eligible mileages is submitted. Based on the criteria, Shangchi Automobile (formerly known as Suzhou E-Motors) was eligible for government manufacturing rebates and had $5,755,237 as manufacturing rebate receivable as of December 31, 2020.

In 2021, the Chinese Ministry of Finance, the Chinese Ministry of Science and Technology, the Chinese Ministry of Industry and Information Technology, and the Chinese National Development and Reform Commission implemented a new policy which requires the minimum number of alternative energy vehicles for manufacturing rebate application shall be 10,000 for passenger vehicles and 1,000 for commercial use vehicles.

The Company determined that there is remote possibility to successfully claim the manufacturing rebate under the newly implemented policy. As a result, the Company recorded 100% allowance against the manufacturing rebate receivable as of December 31, 2021.

Note 11 – Leases

Effective January 1, 2019, the Company adopted ASC 842, the new lease accounting standard using a modified retrospective transition method which allowed the Company not to recast comparative periods presented in its consolidated financial statements. In addition, the Company elected the package of practical expedients, which allowed the Company to not reassess whether any existing contracts contain a lease, to not reassess historical lease classification as operating or finance leases, and to not reassess initial direct costs. The Company has not elected the practical expedient to use hindsight to determine the lease term for its leases at transition. The Company combines the lease and non-lease components in determining the ROU assets and related lease obligation. Adoption of this standard resulted in the recording of operating lease ROU assets and corresponding operating lease liabilities as disclosed below and had no impact on retained earnings as of December 31, 2021. ROU assets and related lease obligations are recognized at commencement date based on the present value of remaining lease payments over the lease term.

During the year ended December 31, 2020, 944,655 (split-adjusted 94,465) common shares were issued upon excise of investor warrants at $0.001 (split-adjusted $0.01) per share. The exercise price of such warrants was reduced from $4.25 (split-adjusted $42.5) per share to $0.001 (split-adjusted $0.01) per share by virtue of the Company’s entry into a securities purchase agreement on November 20, 2020.

November 2020 Offering Warrants

In connection with and upon closing of the offering on November 24, 2020, the Company issued registered warrants to purchase up to 2,754,820 (split-adjusted 275,482) common shares and unregistered warrants to purchase up to 3,305,788 (split-adjusted 330,579) common shares. Such registered and unregistered warrants are immediately exercisable, expire five years from the date of issuance and have an exercise price of $1.81 (split-adjusted $18.10) per share. The placement agent also received unregistered warrants in connection with this offering exercisable for up to 363,637 (split-adjusted 36,364) common shares at $1.815 (split-adjusted $18.15) per share, exercisable between May 24, 2021 to November 24, 2023.

Management determined that these warrants meet the requirements for equity classification under ASC 815-40 because they are indexed to its own stock. The warrants were recorded at their fair value on the date of issuance as a component of shareholders’ equity.

As of December 31, 2021, the total number of common shares underlying registered and unregistered warrants outstanding was 6,557,635 (split-adjusted 655,764). These warrants have weighted average of remaining life of 3.73 years and weighted average exercise price of $1.87 (split-adjusted $18.70).

Share Consolidation

On February 24, 2022, the Company’s Board approved a share consolidation of the Company’s common shares at the ratio of one-for-ten reverse split with the effective date of February 25, 2022. The objective of the share consolidation is to enable the company to regain compliance with NASDAQ Marketplace Rule 5550(a)(2) and maintain its listing on Nasdaq.

As a result of the share consolidation, each 10 common shares outstanding automatically combines and converts to one issued and outstanding common share without any action on the part of the shareholder. The share consolidation reduces the number of common shares issued and outstanding from 63,994,606 to 6,399,460. The authorized number of common shares will be reduced by the same one-for-ten ratio from 600 million to 60 million.

All share information included in the consolidated financial statements and notes thereto have been retroactively adjusted for the one-for-ten reverse split occurred on the first day of the first period presented. (See Note 22).

Note 18 – Long Term Investments

On January 10, 2018, the Company invested approximately $18.8 million (or RMB 120 million) to acquire 18% equity interest in Libo Haokun Stone Co., Ltd. (“Libo Haokun”). Libo Haokun holds a government-issued permit and has the exclusive right to mine a 0.11-square-kilometer marble quarry in the central area of Guizhou province, China. Libo Haokun obtained the permit to mine the quarry from the local government in September 2016. The permit was renewed in July 2020 and is further renewable by July 2023.

On November 29, 2019, the Company entered into an investment agreement (the “Investment Agreement”) with Jingning Zhonggang Mining Co., Ltd. (“Jingning Zhonggang”) through Lishui Tantech to acquire 18% of the equity interest of Fuquan Chengwang Mining Co., Ltd. (“Fuquan Chengwang”), a wholly-owned subsidiary of Jingning Zhonggang, at a price of $7.3 million (RMB46.32 million). The consideration equals 18% of RMB257.35 million, the value of the mining right under a permit being renewed by Fuquan Chengwang according to an evaluation report. Fuquan Chengwang is a basalt mining company.

Pursuant to the Investment Agreement, Tantech is obligated to pay the consideration within 30 days after Fuquan Chengwang completes the recording process with the local industrial and commerce administration for transfer of the share ownership. Pursuant to the Investment Agreement, after the transfer of the 18% share ownership, if the value of Fuquan Chengwang is lower than RMB257.35 million according to the financial statements audited by an accounting firm approved by the Tantech, Jingning Zhonggang will be obligated to refund to Tantech the overpaid amount. The payment could be in the form of cash, shares, or other assets with the same value, as selected by Tantech.

After a series of transactions and reorganization, as of December 31, 2019, the Company and Jingning Zhonggang owns 18% and 82% of Libo Haokun, respectively, through Jingning Meizhongkuang Industry Co., Ltd. (“Jingning Meizhongkuang”). Jingning Meizhongkuang owns 100% of Fuquan Chengwang. The Agreements would enable Tantech to indirectly hold a 18% stake in Fuquan Chengwang through holding 18% of the equity interest of Jingning Meizhongkuang.

On April 3, 2020, Lishui Ansheng Energy Technology Co., a third party, signed an investment agreement with Jingning Meizhongkuang to invest in Fuquan Chengwang by paying $7.3 million (RMB 46.5 million) to exchange 18% of the interest of Fuquan Chengwang. After the transaction, the Company’s indirect interest in Fuquan Chengwang was diluted from 18% to 14.76% through holding 18% of the equity interest of Jingning Meizhongkuang.

Fuquan Chengwang received the renewed mining permit in March 2021, and expiration date is March 2024. The mining permit provides it the right to mine a 0.2607-square-kilometer basalt quarry in Fuquan City, Guizhou Province, China.

As the Company did not have significant influence over the equity investees, the investments were accounted for using the cost method. For the year ended December 31, 2021, 2020 and 2019, the Company did not recognize any impairment losses for the long-term investments.

Segment Information

Note 20 – Segment Information

The Company uses the “management approach” in determining reportable operating 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. Due to business strategic changes, the Company merged consumer products segment and trading segment. As a result, the Company has determined that it has two operating segments as defined by ASC 280, “Segment Reporting”: consumer products and electric vehicles (“EV”). Consumer products segment manufactures, sell and trade Charcoal Doctor branded products and BBQ charcoal in China. The EV segment was acquired in July 2017. Management, including the chief operating decision maker, reviews operation results of consumer products and electric vehicles separately.

Summary of significant accounting policies

Principal of Consolidation

Principal of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The consolidated financial statements include the financial statements of Tantech BVI and its subsidiaries (collectively, the “Company”). All significant inter-company balances and transactions are eliminated upon consolidation.

Non-controlling interest

Non-controlling interest

Non-controlling interest represents 30% of the equity interest in Shangchi Automobile and its subsidiary Shenzhen Yimao owned by Zhangjiagang Jinke Chuangtou Co., Ltd., which is not under the Company’s control.

Use of Estimates

Use of Estimates

In preparing the consolidated financial statements in conformity with US GAAP, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the dates of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting year. Significant items subject to such estimates and assumptions include the fair value estimates used in the useful lives of property and equipment and intangible assets, allowances pertaining to the allowance for doubtful accounts of accounts receivable, advance to suppliers and other receivables, the valuation of inventories, the impairment of long-lived assets, and the realizability of deferred tax assets.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurements”, defines fair value, establishes a three-level valuation hierarchy for fair value measurements and enhances disclosure requirements.

The three levels are defined as follows:

Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted market prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data.

Level 3 - inputs to the valuation methodology are unobservable.

Unless otherwise disclosed, the fair value of the Company’s financial instruments including cash, restricted cash, accounts receivable, advances to suppliers, other receivables, accounts payable, customer deposits, accrued expenses, short term bank loans and bank acceptance notes payable approximates their recorded values due to their short-term maturities.

Cash and cash equivalents

Cash and cash equivalents

For purposes of the statements of cash flows, the Company considers all highly liquid instruments purchased with an original maturity of three months or less and money market accounts to be cash equivalents. All cash balances are in bank accounts in PRC and are not insured by the Federal Deposit Insurance Corporation or other programs.

Restricted Cash

Restricted Cash

For the year ended December 31, 2020, restricted cash represents the cash of $220,109 required deposits as a part of collateral for bank acceptance notes payable and letters of credit. The Company is required to maintain 0% to 100% of the balance of the bank acceptance notes payable in restricted cash to ensure future credit availability. The Company earns interest at a variable rate per month on this restricted cash.

For the year ended December 31, 2021, the Company’s restricted cash represents the cash of $422,832 remains frozen in the bank accounts of one of the Company’s subsidiaries as the result of the ongoing lawsuit filed by Mr. Hengwei Chen to against the Company (see Note 15).

Concentrations of credit risk

Concentrations of credit risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash, trade accounts receivable and advances to suppliers. All of the Company’s cash is maintained with banks within the People’s Republic of China of which no deposits are covered by insurance. The Company has not experienced any losses in such accounts. A significant portion of the Company’s sales are credit sales which are primarily to customers whose ability to pay is dependent upon the industry economics prevailing in these areas. The Company also makes cash advances to certain suppliers to ensure the stable supply of key raw materials. The Company performs ongoing credit evaluations of its customers and key suppliers to help further reduce credit risk.

Accounts receivable

Accounts receivable

Accounts receivable are presented at invoiced amount net of an allowance for doubtful accounts. The Company maintains an allowance for doubtful accounts for estimated losses. The Company reviews its accounts receivable on a periodic basis and makes general and specific allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, the Company considers many factors, including the age of the balance, customer’s payment history, its current credit-worthiness and current economic trends. Accounts are written off after efforts at collection prove unsuccessful.

Inventory

Inventory

The Company values its inventories at the lower of cost, determined on a weighted average basis, or net realizable value. The Company reviews its inventories periodically to determine if any markdown is necessary for potential obsolescence or if a write-down is necessary if the carrying value exceeds net realizable value.

Advances to suppliers

Advances to suppliers

In order to ensure a steady supply of raw materials, the Company is required from time to time to make cash advances when placing its purchase orders. The Company reviews its advances to suppliers on a periodic basis and makes general and specific allowances when there is doubt as to the ability of a supplier to refund an advance or provide supplies to the Company.

Property and Equipment and Construction in Progress

Property and Equipment and Construction in Progress

Property and equipment are stated at cost less accumulated depreciation. The cost of an asset comprises its purchase price and any directly attributable costs of bringing the asset to its present working condition and location for its intended use.

Note 2 – Summary of Significant Accounting Policies (continued)

Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets. The estimated useful lives for significant property and equipment are as follows:

Buildings	20 years
Machinery and equipment	5 - 10 years
Transportation equipment	4 - 5 years
Office equipment	4 - 5 years
Electronic equipment	3 - 5 years

Repairs and maintenance costs are normally charged to earnings in the year in which they are incurred. In situations where it can be clearly demonstrated that the expenditure has resulted in an increase in the future economic benefits expected to be obtained from the use of the asset, the expenditure is capitalized as an additional cost of the asset.

Construction in progress includes direct costs of construction or acquisition of equipment, interest expense associated with the loans used for the construction and design fees incurred. Capitalization of these costs ceases and the construction in progress is transferred to plant and equipment when substantially all the activities necessary to prepare the assets for their intended use are completed. No depreciation is provided until it is completed and ready for its intended use.

Intangible assets

Intangible assets

Intangible assets are acquired individually or as part of a group of assets, and are initially recorded at cost. The cost of a group of assets acquired in a transaction is allocated to the individual assets based on their relative fair values. Intangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets with finite useful lives are amortized using a straight-line method over the period of estimated useful life. The estimated useful lives of the Company’s intangible assets are as follows:

	Estimated Useful Life
Licenses and permits	Indefinite
Software	5 - 10 years
Land use right	50 years
Patents	10 years

The Company evaluates intangible assets for impairment whenever events or changes in circumstances indicate that the assets might be impaired.

Long term investments

Long term investments

The Company accounts for investment in equity investees over which it has significant influence but does not own a majority of the equity interest or lack of control using the equity method. For investment in equity investees over which the Company does not have significant influence or the underlying shares the Company invested in are not considered in-substance common stock and have no readily determinable fair value, the cost method accounting is applied.

The Company records the equity method investments at historical cost and subsequently adjusts the carrying amount each period for share of the earnings or losses of the investee and other adjustments required by the equity method of accounting. Dividends received from the equity method investments are recorded as reductions in the cost of such investments. The Company records the cost method investments at historical cost and subsequently record any dividends received from the net accumulated earnings of the investee as income. Dividends received in excess of earnings are considered a return of investment and are recorded as reductions in the cost of the investments.

Note 2 – Summary of Significant Accounting Policies (continued)

Investment in equity investees are evaluated for impairment when facts or circumstances indicate that the fair value of the investment is less than its carrying value. An impairment is recognized when a decline in fair value is determined to be other-than-temporary. The Company reviews several factors to determine whether a loss is other-than-temporary. These factors include, but are not limited to, the: (i) nature of the investment; (ii) cause and duration of the impairment; (iii) extent to which fair value is less than cost; (iv) financial condition and near term prospects of the investments; and (v) ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances, such as a significant adverse change to market conditions that will impact the future use of the assets, indicate that the carrying amount of an asset may not be fully recoverable. When these events occur, the Company evaluates the recoverability of long-lived assets by comparing the carrying amount of the assets to the future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Company recognizes an impairment loss based on the excess of the carrying amount of the assets over their fair value. Fair value is generally determined by discounting the cash flows expected to be generated by the assets, when the market prices are not readily available.

Customer Deposits

Customer Deposits

Customer deposits represent amounts received from customers in advance of shipments relating to the sales of the Company’s products.

Loan Payable to Third Parties

Loan Payable to Third Parties

Loan payable to third parties represent amounts the Company borrowed from third parties for working capital purpose. As of December 31, 2021, the balance amounted $7,002,385, the balances are unsecured with interest rate 6% per annum and with one year term from December 17, 2021 to December 16, 2022. If the Company fails to repay the debt, the Company shall pay the third parties for the liquidated damages at the rate of thousandths of the amount in arrears per day, and also compensate the legal costs, execution fees, etc. incurred in realizing the creditor’s rights. As of December 31, 2020, the balance amounted $306,600, the balance is unsecured, interest-free and due upon demand.

Leases

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842). The standard requires lessees to recognize lease assets and lease liabilities on the balance sheet and requires expanded disclosures about leasing arrangements. The new standard establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months.

The Company adopted ASC 842 on January 1, 2019 on a modified retrospective basis and elected the practical expedients permitted under the transition guidance, which allows the Company to carryforward the historical lease classification, the assessment on whether a contract is or contains a lease, and the initial direct costs for any leases that exist prior to adoption of the new standard. Leases with an initial term of 12 months or less are not recognized on the balance sheet and the associated lease payments are included in the consolidated statements of comprehensive income (loss) on a straight-line basis over the lease term. The standard did not materially impact our consolidated net earnings and cash flows.

Revenue Recognition

Revenue Recognition

The Company adopted ASC Topic 606 Revenue from Contracts with Customers (“ASC 606”) on January 1, 2018 using the modified retrospective approach. There is no adjustment to the opening balance of retained earnings at January 1, 2018 since there was no change to the timing and pattern of revenue recognition upon adoption of ASC 606. Under ASC 606, revenue is recognized when control of promised goods or services is transferred to the Company’s customers in an amount of consideration to which an entity expects to be entitled to in exchange for those goods or services. The Company’s revenues are primarily derived from the following sources:

Sales of products: The Company recognizes sales revenue, net of sales taxes and estimated sales returns, at the time the product is delivered to the customer and control is transferred (point of sale).

For the Company’s electric vehicles sales contracts, the Company provides a warranty for 12 months from the products are delivered. The Company determines such product warranty is an assurance-type warranty and is not a separated performance obligation in revenue recognition, because the nature of warranty is to provide assurance that a product will function as expected and in accordance with customer’s specification. The Company estimates the warranty costs when the promised good is delivered to the customer and accrues as warranty liabilities.

Commission income: The Company acts as an agent without assuming the risks and rewards of ownership of the goods and reports the revenue on a net basis. Revenue is recognized based on the completion of the contracted service.

Government manufacturing rebate income: The Company sells electric vehicles in China and is eligible for a government manufacturing rebate on each qualifying electric vehicle sold. The government manufacturing rebates are recognized as part of revenue when sales are finalized, amount of rebates can be reasonably estimated and collection is assured. The collectability of rebates can be assured as long as the sales are deemed qualifying based on the criteria set by the government.

Revenue is reported net of all value added taxes. The Company does not routinely permit customers to return products and historically, customer returns have been immaterial.

Cost of Revenues

Cost of Revenues

Cost of revenues includes cost of raw materials purchased, inbound freight cost, cost of direct labor, depreciation expense and other overhead. Write-down of inventory for lower of cost or net realizable value adjustments is also recorded in cost of revenues.

Shipping and Handling

Shipping and Handling

Shipping and handling costs are expensed as incurred and included in selling expenses.

Subsidy Income

Subsidy Income

The Company periodically receives various government grants such as “High Technology Projects Subsidy” and “Scientific Research Grant”. There is no guarantee the Company will continue to receive such grants in the future.

Foreign Currency Translation

Foreign Currency Translation

The Company’s financial information is presented in U.S. dollars. The functional currency of the Company’s subsidiaries in the PRC is the RMB, the currency of the PRC. Any subsidiary transactions, which are denominated in currencies other than RMB, are translated into RMB at the exchange rate quoted by the People’s Bank of China prevailing at the dates of the transactions, and exchange gains and losses are included in the statements of comprehensive income (loss) as foreign currency transaction gain or loss. The consolidated financial statements of the Company have been translated into U.S. dollars in accordance with ASC 830, “Foreign Currency Matters”. The financial information is first prepared in RMB and then is translated into U.S. dollars at period-end exchange rates for assets and liabilities and average exchange rates for revenue and expenses. Capital accounts are translated at their historical exchange rates when the capital transactions occurred. The effects of foreign currency translation adjustments are included as a component of accumulated other comprehensive income in stockholders’ equity. Cash flows from the Company’s operations are calculated based upon the local currencies using the average translation rate. As a result, amounts related to assets and liabilities reported on the statements of cash flows will not necessarily agree with changes in the corresponding balances on the balance sheets.

The following table outlines the currency exchange rates that were used in creating the consolidated financial statements in this report:

	December 31, 2021			December 31, 2020			December 31, 2019
US$: RMB exchange rate	Period End	$	0.1569	Period End	$	0.1533	Period End	$	0.1436
	Average	$	0.1550	Average	$	0.1448	Average	$	0.1448

Research and development costs

Research and development costs

Research and development expenses include costs directly attributable to the conduct of research and development projects, including the cost of salaries and other employee benefits, testing expenses, consumable equipment and consulting fees prior to the establishment of technological feasibility. All costs associated with research and development are expensed as incurred.

Comprehensive Income (loss)

Comprehensive Income (loss)

Comprehensive income (loss) consists of two components, net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) refers to revenue, expenses, gains and losses that under GAAP are recorded as an element of stockholders’ equity but are excluded from net income (loss). Other comprehensive income (loss) consists of foreign currency translation adjustment from those subsidiaries not using the U.S. dollar as their functional currency.

Income Taxes

Income Taxes

The Company’s subsidiaries in China are subject to the income tax laws of the PRC. No taxable income was generated outside the PRC as of December 31, 2021. The Company accounts for income taxes in accordance with ASC 740, “Income Taxes”. ASC 740 requires an asset and liability approach for financial accounting and reporting for income taxes and allows recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or future deductibility is uncertain.

ASC 740-10-25 prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken (or expected to be taken) in a tax return. It also provides guidance on the recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, years open for tax examination, accounting for income taxes in interim periods and income tax disclosures. The statute of limitation on the PRC tax authority’s audit or examination of previously filed tax returns expires three years from the date they were filed. There were no material uncertain tax positions as of December 31, 2021 and 2020.

Value Added Tax ("VAT")

Value Added Tax (“VAT”)

The Company is subject to VAT for selling merchandise. The applicable VAT rate is 11% or 13% or 17% (depending on the type of goods involved) for products sold in the PRC. The applicable VAT rate of 17% and 11% decreased to 16% and 10% starting from May 2018, and further decreased to 13% and 9% from April 1, 2019. The amount of VAT liability is determined by applying the applicable tax rate to the invoiced amount of goods sold (output VAT) less VAT paid on purchases made with the relevant supporting invoices (input VAT). Under the commercial practice of the PRC, the Company pays VAT based on tax invoices issued. The tax invoices may be issued subsequent to the date on which revenue is recognized, and there may be a considerable delay between the date on which the revenue is recognized and the date on which the tax invoice is issued. In the event the PRC tax authorities dispute the date on which revenue is recognized for tax purposes, the PRC tax office has the right to assess a penalty based on the amount of taxes which is determined to be late or deficient, with any penalty being expensed in the period when a determination is made by the tax authorities that a penalty is due. During the reporting periods, the Company had no dispute with PRC tax authorities and there was no tax penalty incurred.

Earnings (loss) per Share ("EPS")

Earnings (loss) per Share (“EPS”)

The Company computes earnings (loss) per share (“EPS”) in accordance with ASC 260, “Earnings per Share” (“ASC 260”), and SEC Staff Accounting Bulletin No. 98 (“SAB 98”). ASC 260 requires companies with complex capital structures to present basic and diluted EPS. Basic EPS is measured as net income divided by the weighted average common shares outstanding for the period. Diluted EPS is similar to basic EPS but presents the dilutive effect on a per share basis of potential common shares (e.g., convertible securities, options and warrants) as if they had been converted at the beginning of the periods presented, or issuance date, if later. Potential common shares that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted EPS. As of December 31, 2021 and 2020, the total number of registered and unregistered warrants outstanding both was 6,557,635 (split-adjusted 655,764). For the years ended December 31, 2021, 2020 and 2019, no warrants were included in the diluted income (loss) per share as they would be anti-dilutive.

Statement of Cash Flows

Statement of Cash Flows

In accordance with ASC 230, “Statement of Cash Flows,” cash flows from the Company’s operations are calculated based upon the local currencies. As a result, amounts related to assets and liabilities reported on the statements of cash flows will not necessarily agree with changes in the corresponding balances on the balance sheets.

Risks and Uncertainties

Risks and Uncertainties

The operations of the Company are located in the PRC. Accordingly, the Company’s business, financial condition, and results of operations may be influenced by the political, economic, and legal environments in the PRC, in addition to the general state of the PRC economy. The Company’s operating results may be adversely affected by changes in the political and social conditions in the PRC, and by changes in governmental policies with respect to laws and regulations, anti-inflationary measures, currency conversion and remittance abroad, and rates and methods of taxation, among other things.

The Company’s sales, purchases and expense transactions are denominated in RMB, and primarily all of the Company’s assets and liabilities are also denominated in RMB. The RMB is not freely convertible into foreign currencies under the current law. In China, foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People’s Bank of China, the central bank of China. Remittances in currencies other than RMB may require certain supporting documentation in order to affect the remittance.

Note 2 – Summary of Significant Accounting Policies (continued)

The Company does not carry any business interruption insurance, products liability insurance or any other insurance policy except for a limited property insurance policy. As a result, the Company may incur uninsured losses, increasing the possibility that investors would lose their entire investment in the Company.

COVID-19

COVID-19

The Company’s operations were affected by the recent and ongoing outbreak of the coronavirus disease 2019 (COVID-19) which in March 2020, was declared a pandemic by the World Health Organization. The COVID-19 outbreak is causing lockdowns, travel restrictions, and closures of businesses. The Company’s business has been negatively impacted by the COVID-19 coronavirus outbreak to certain extent in fiscal 2020.

From late January 2020 to the middle of February 2020, the Company had to temporarily suspend our manufacturing activities due to government restrictions. During the temporary business closure period, our employees had very limited access to our manufacturing facilities and the shipping companies were not available and as a result, the Company experienced difficulty delivering our products to the customers on a timely basis. In addition, due to the COVID-19 outbreak, some of the customers or suppliers may experience financial distress, delay or default on their payments, reduce the scale of their business, or suffer disruptions in their business due to the outbreak. Any increased difficulty in collecting accounts receivable, delayed raw materials supply, bankruptcy of small and medium businesses, or early termination of agreements due to deterioration in economic conditions could negatively impact our results of operations.

As of the date of this filing, the COVID-19 coronavirus outbreak in China appears to be controlled and most provinces and cities have resumed business activities under the guidance and support of the government. In light of the current situation, the Company believes that the impact of the COVID-19 outbreak on the business is both temporary and limited, and that the revenues have started growing again in fiscal 2021. However, there is still significant uncertainty regarding the possibility of another wave of infections, and the breadth and duration of business disruptions related to COVID-19, which could continue to have material impact to the Company’s operations.

Recent accounting pronouncements

Recent accounting pronouncements

The Company considers the applicability and impact of all accounting standards updates (“ASUs”). Management periodically reviews new accounting standards that are issued.

In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes” (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 will simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company adopted this guidance and this guidance did not have a material impact on the consolidated financial statements.

Note 2 – Summary of Significant Accounting Policies (continued)

In January 2020, the FASB issued ASU 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) (“ASU 2020-01”), which is intended to clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. ASU 2020-01 is effective for the Company beginning January 1, 2021. The Company adopted this guidance and this guidance did not have a material impact on the consolidated financial statements.

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt — Modifications and Extinguishments (Subtopic 470-50), Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (“ASU 2021-04”). ASU 2021-04 provides guidance as to how an issuer should account for a modification of the terms or conditions or an exchange of a freestanding equity-classified written call option (i.e., a warrant) that remains classified after modification or exchange as an exchange of the original instrument for a new instrument. An issuer should measure the effect of a modification or exchange as the difference between the fair value of the modified or exchanged warrant and the fair value of that warrant immediately before modification or exchange and then apply a recognition model that comprises four categories of transactions and the corresponding accounting treatment for each category (equity issuance, debt origination, debt modification, and modifications unrelated to equity issuance and debt origination or modification). ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the guidance provided in ASU 2021-04 prospectively to modifications or exchanges occurring on or after the effective date. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt ASU 2021-04 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The Company adopted this guidance and this guidance did not have a material impact on the consolidated financial statements.

Except for the above-mentioned pronouncements, there are no new recent issued accounting standards that will have material impact on the consolidated financial statements.
