COVID-19 has spread rapidly to many parts of the PRC and other parts of the world in the first quarter of 2020, which has caused significant volatility in the PRC and international markets. The ongoing COVID-19 pandemic has resulted in a reduction in economic activity by adversely affecting production, creating supply chain and market disruption. Substantially most of our revenues and our workforce are concentrated in China. Consequently, the Company has experienced delayed customer payments and rescheduled customer orders. Since the COVID-19 pandemic has been gradually contained in China, our revenue and gross margin for the year ended December 31, 2020 and 2021 has not been adversely affected. However, any potential impact to the Company’s results will depend on, to a large extent, future developments and new information that may emerge regarding the duration and severity of the COVID-19 and the actions taken by government authorities and other entities to contain the COVID-19 or treat its impact, almost all of which are beyond the Company’s control.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="text-decoration:underline">Reorganization</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">A reorganization of the Company’s legal structure was completed on August 27, 2018.

Since inception, Powerbridge Zhuhai and Mr. Tianfei Feng have only made nominal investments in Powerbridge Beijing and no substantial business operations have occurred; as a result, Powerbridge Zhuhai and Mr. Tianfei Feng agreed to deregister the entity. Mr. Tianfei Feng later became the Company’s Chief Research and Development Officer and the technology research and development activities originally conducted in Powerbridge Beijing are now conducted through the Beijing branch of Powerbridge Zhuhai.

COVID-19 has spread rapidly to many parts of the PRC and other parts of the world in the first quarter of 2020, which has caused significant volatility in the PRC and international markets. The ongoing COVID-19 pandemic has resulted in a reduction in economic activity by adversely affecting production, creating supply chain and market disruption. Substantially most of our revenues and our workforce are concentrated in China. Consequently, the Company has experienced delayed customer payments and rescheduled customer orders. Since the COVID-19 pandemic has been gradually contained in China, our revenue and gross margin for the year ended December 31, 2021 has not been adversely affected. However, any potential impact to the Company’s results will depend on, to a large extent, future developments and new information that may emerge regarding the duration and severity of the COVID-19 and the actions taken by government authorities and other entities to contain the COVID-19 or treat its impact, almost all of which are beyond the Company’s control.</p> 2012500 5 262500 5 10062500 8021987 11508747 0.001 the board of directors approved a reverse stock split of the Company’s authorized number of Ordinary Shares at a ratio of 1-0.6. 300000000 0.00166667 6905248 6905248 0.849 0.55 0.45 1 1 1 <table cellpadding="0" cellspacing="0" style="width: 100%; border-collapse: collapse; font-size: 10pt"> <tr> <td style="vertical-align: bottom; border-bottom: black 1.5pt solid"><span style="font-size: 10pt"><b>Major subsidiaries</b></span></td> <td style="vertical-align: bottom"> </td> <td style="vertical-align: bottom; border-bottom: black 1.5pt solid; text-align: center"><span style="font-size: 10pt"><b>Percentage of<br/> Ownership</b></span></td> <td style="vertical-align: top"> </td> <td style="vertical-align: bottom"> </td> <td style="vertical-align: bottom; border-bottom: black 1.5pt solid; text-align: center"><span style="font-size: 10pt"><b>Date of<br/> Incorporation</b></span></td> <td style="vertical-align: bottom"> </td> <td style="vertical-align: bottom; border-bottom: black 1.5pt solid; text-align: center"><span style="font-size: 10pt"><b>Place of<br/> Incorporation</b></span></td> <td style="vertical-align: bottom"> </td> <td style="vertical-align: bottom; border-bottom: black 1.5pt solid; text-align: center"><span style="font-size: 10pt"><b>Major Operation</b></span></td></tr> <tr style="background-color: rgb(204,238,255)"> <td style="vertical-align: top; width: 32%"><span style="font-size: 10pt">Powerbridge Technologies Co., Ltd.

The Company has historically funded its working capital needs primarily from public offering, operations, bank loans, advance payments from customers and shareholders. The working capital requirements are affected by the efficiency of operations, the numerical volume and dollar value of revenue contracts, the progress or execution on customer contracts, and the timing of accounts receivable collections. </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">In assessing its liquidity, the Company monitors and analyzes its cash on hand, its ability to generate sufficient revenue sources in the future and its operating and capital expenditure commitments. As of December 31, 2021, the Company had cash of approximately $7.0 million. On August 7, 2021, the Company entered into an amendment (the “Closing Statement”) to the securities purchase agreement initially entered into with YA on April 9, 2021 (the “Purchase Agreement”). Pursuant to the Purchase Agreement, YA agreed to purchase convertible notes (the “Notes”) in the aggregate principal amount of US$7,000,000 (the “Principal”), which shall be convertible into the Company’s ordinary shares par value $0.00166667 per share, and a warrant (the “Warrant”) to purchase 571,429 Ordinary Shares (the “Offering”), for gross proceeds of approximately US$6,790,000. The first closing of the offer and sale of the first Note (the “First Note”) in the principal amount of $4,000,000 was completed on April 9, 2021. Pursuant to the Closing Statement, the Company and YA agreed that, among other thing, (i) the Principal shall be increased to US$8,000,000; (ii) the principal amount of the second Note (the “Second Note”) is reduced from $3,000,000 to $2,000,000; (iii) the number of ordinary shares to be issued pursuant to the Warrant shall be increased from 571,429 to 653,061; and (iv) promptly after the Securities and Exchange Commission (the “SEC”) declares effective a registration statement to be filed by the Company pursuant to a registration rights agreement (the “Registration Rights Agreement”), YA agrees to purchase the third Note (the “Third Note”) in the principal amount of $2,000,000, which shall have identical terms as those of the Second Note. Except as expressly amended by the Closing Statement, the Second Note has essentially identical terms to the First Note. The closing of the second Note in the principal amount of $2,000,000 was completed on August 9, 2021. The Company believes that its cash on hand and financing cash flows will be sufficient to fund its operations over at least the next 12 months from the date of this report. However, the Company may need additional cash resources in the future if the Company experiences changed business conditions or other developments, and may also need additional cash resources in the future if the Company wishes to pursue opportunities for investment, acquisition, strategic cooperation or other similar actions. If it is determined that the cash requirements exceed the Company’s amounts of cash on hand, the Company may seek to issue debt or equity securities or obtain a credit facility.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: center"><b> </b></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="text-decoration:underline">Use of estimates</span></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the periods presented.

These services also require significant production and customization. Upon delivery of the services, customer acceptance is generally required. In the same contract, the Company is generally required to provide post-contract customer support (“PCS’) for a period from three months to three years (“PCS period”) after the customized application development services are delivered. The type of services for PCS clause is generally not specified in the contracts or as stand-ready services on when-and-if-available basis. The unspecified PCS is stand-ready service on when-and-if-available basis. It grants the customers on line and telephone access to technical support personnel during the term of the service.

Pursuant to the contract terms, the Company has enforceable right on payments for the work performed.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Company sometimes provides a warranty for its application development service contracts. The warranty period is typically 12-36 months upon the completion of the application development service. In accordance with ASC 606-10-25-19, the Company believes the warranty provision in the contracts generally represents service-type warranty, which is a distinct performance obligation and the Company also provides the similar service on standalone basis and customers can benefit from the related service-type warranty service. For the service warranty component, the customer simultaneously receives and consumes the benefits provided by the company performance over the warranty term, therefore, the service warranty is satisfied over time. The revenue allocated to the service warranty is recognized over the warranty period.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"><b> </b></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Company assesses that application development service, PCS or specific service and service-type warranty service, if applicable, are distinct performance obligations in the application development service contracts. The Company provides these services on standalone basis and customers are able to benefit from each of the service on its own. In addition, the timing of delivery of these performance obligations can be separately identifiable in the contracts. The transaction price is allocated to these identified performance obligations based on the relative standalone selling prices. The transaction price allocated to PCS or unspecific service and service-type warranty, if applicable, on a straight-line method over the contractual period. Revenue allocated to specified PCS is recognized as the related services are rendered. The transaction price allocated to application development service is recognized over time as the Company’s performance creates or enhances the project controlled by the customer and the control is transferred continuously to our customers. The Company uses an input method based on cost incurred as the Company believes that this method most accurately reflects the Company’s progress toward satisfaction of the performance obligation, which usually takes less than one year. Under this method, the transaction price allocated to application development service is recognized as work is performed based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations. </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Incurred costs include all direct material, labor and subcontract costs, and those indirect costs related to application development performance, such as indirect labor, supplies, and tools. Cost-based input method requires the Company to make estimates of revenues and costs to complete the construction. In making such estimates, significant judgment is required to evaluate assumptions related to the costs to complete the application development, including materials, labor, and other system costs. The Company’s estimates are based upon the professional knowledge and experience of our engineers and project managers to assess the contract’s schedule, performance, technical matters. The Company has adequate cost history and estimating experience, and with respect to which management believes it can reasonably estimate total development costs. If the estimated costs are greater than the related revenues, the Company recognizes the entire estimated loss in the period the loss becomes known and can be reasonably estimated. Changes in estimates for application development services include but not limited to cost forecast changes and change orders. The cumulative effect of changes in estimates is recorded in the period in which the revisions to estimates are identified and the amounts can be reasonably estimated. To date, the Company has not incurred a material loss on any contracts. However, as a policy, provisions for estimated losses on such engagements will be made during the period in which a loss becomes probable and can be reasonably estimated. If contract modifications result in additional goods or services that are distinct from those transferred before the modification, they are accounted for prospectively as if the Company entered into a new contract. If the goods or services in the modification are not distinct from those in the original contract, sales and gross profit are adjusted using the cumulative catch-up method for revisions in estimated total contract costs and contract values.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">In certain application development service arrangements, the Company sells and delivers IT equipment on standalone basis prior to the delivery of the services. In these cases, the Company controls the IT equipment before they are transferred to the customer.

Thus, the Company considers it should recognize revenue as a principal in the gross amount of consideration to which it is entitled in exchange for the IT equipment delivered. The Company assesses the sale of equipment is separately identifiable from other promises in the contract and it is distinct performance obligation within the context of the contract.

Pursuant to the Closing Statement, the Company and YA agreed that, among other thing, (i) the Principal shall be increased to US$8,000,000; (ii) the principal amount of the second Note (the “Second Note”) is reduced from $3,000,000 to $2,000,000; (iii) the number of ordinary shares to be issued pursuant to the Warrant shall be increased from 571,429 to 653,061; and (iv) promptly after the Securities and Exchange Commission (the “SEC”) declares effective a registration statement to be filed by the Company pursuant to a registration rights agreement (the “Registration Rights Agreement”), YA agrees to purchase the third Note (the “Third Note”) in the principal amount of $2,000,000, which shall have identical terms as those of the Second Note. Except as expressly amended by the Closing Statement, the Second Note has essentially identical terms to the First Note. The closing of the second Note in the principal amount of $2,000,000 was completed on August 9, 2021.

Assets and liabilities denominated in foreign currencies at the balance sheet date are translated at the applicable rates of exchange in effect at that date. The equity denominated in the functional currencies is translated at the historical rates of exchange at the time of capital contributions. Because cash flows are translated based on the average translation rates, amounts related to assets and liabilities reported on the consolidated statements of cash flows will not necessarily agree with changes in the corresponding balances on the consolidated balance sheets.

These services also require significant production and customization. Upon delivery of the services, customer acceptance is generally required. In the same contract, the Company is generally required to provide post-contract customer support (“PCS’) for a period from three months to three years (“PCS period”) after the customized application development services are delivered. The type of services for PCS clause is generally not specified in the contracts or as stand-ready services on when-and-if-available basis. The unspecified PCS is stand-ready service on when-and-if-available basis. It grants the customers on line and telephone access to technical support personnel during the term of the service.

Pursuant to the contract terms, the Company has enforceable right on payments for the work performed.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Company sometimes provides a warranty for its application development service contracts. The warranty period is typically 12-36 months upon the completion of the application development service. In accordance with ASC 606-10-25-19, the Company believes the warranty provision in the contracts generally represents service-type warranty, which is a distinct performance obligation and the Company also provides the similar service on standalone basis and customers can benefit from the related service-type warranty service. For the service warranty component, the customer simultaneously receives and consumes the benefits provided by the company performance over the warranty term, therefore, the service warranty is satisfied over time.

The Company provides these services on standalone basis and customers are able to benefit from each of the service on its own. In addition, the timing of delivery of these performance obligations can be separately identifiable in the contracts. The transaction price is allocated to these identified performance obligations based on the relative standalone selling prices. The transaction price allocated to PCS or unspecific service and service-type warranty, if applicable, on a straight-line method over the contractual period. Revenue allocated to specified PCS is recognized as the related services are rendered. The transaction price allocated to application development service is recognized over time as the Company’s performance creates or enhances the project controlled by the customer and the control is transferred continuously to our customers. The Company uses an input method based on cost incurred as the Company believes that this method most accurately reflects the Company’s progress toward satisfaction of the performance obligation, which usually takes less than one year. Under this method, the transaction price allocated to application development service is recognized as work is performed based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations. </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Incurred costs include all direct material, labor and subcontract costs, and those indirect costs related to application development performance, such as indirect labor, supplies, and tools. Cost-based input method requires the Company to make estimates of revenues and costs to complete the construction. In making such estimates, significant judgment is required to evaluate assumptions related to the costs to complete the application development, including materials, labor, and other system costs. The Company’s estimates are based upon the professional knowledge and experience of our engineers and project managers to assess the contract’s schedule, performance, technical matters. The Company has adequate cost history and estimating experience, and with respect to which management believes it can reasonably estimate total development costs. If the estimated costs are greater than the related revenues, the Company recognizes the entire estimated loss in the period the loss becomes known and can be reasonably estimated. Changes in estimates for application development services include but not limited to cost forecast changes and change orders. The cumulative effect of changes in estimates is recorded in the period in which the revisions to estimates are identified and the amounts can be reasonably estimated. To date, the Company has not incurred a material loss on any contracts. However, as a policy, provisions for estimated losses on such engagements will be made during the period in which a loss becomes probable and can be reasonably estimated. If contract modifications result in additional goods or services that are distinct from those transferred before the modification, they are accounted for prospectively as if the Company entered into a new contract. If the goods or services in the modification are not distinct from those in the original contract, sales and gross profit are adjusted using the cumulative catch-up method for revisions in estimated total contract costs and contract values.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">In certain application development service arrangements, the Company sells and delivers IT equipment on standalone basis prior to the delivery of the services. In these cases, the Company controls the IT equipment before they are transferred to the customer. The Company has the right to direct the suppliers and control the goods or assets transferred to its customers. Thus, the Company considers it should recognize revenue as a principal in the gross amount of consideration to which it is entitled in exchange for the IT equipment delivered. The Company assesses the sale of equipment is separately identifiable from other promises in the contract and it is distinct performance obligation within the context of the contract.

Management considers the cumulative earnings and projected future taxable income in making this assessment. Recovery of substantially all of the group’s deferred tax assets is dependent upon the generation of future income, exclusive of reversing taxable temporary differences. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are recoverable, management provided $738,187 and $517,537 valuation allowance against the deferred tax assets that the Company does not expect to realize at December 31, 2021 and 2020, respectively.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><b> </b></p><table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%"> <tr style="vertical-align: top"> <td style="width: 48px"> </td> <td style="width: 24px"><span style="font-size: 10pt">(b)</span></td> <td style="text-align: justify"><span style="font-size: 10pt"><span style="text-decoration:underline">Value added tax</span></span></td></tr> </table><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Enterprises who sell goods in the PRC are subject to a value added tax in accordance with PRC laws.

The purpose of the Plan is to attract and retain the best available personnel and to promote the success of the Company’s business. The Board authorized that the maximum aggregate number of ordinary shares reserved and available pursuant to this Plan shall be the aggregate of (i) 1,035,787 shares, and (ii) on each January 1, starting with January 1, 2019, an additional number of shares equal to the lesser of (A) 2% of the outstanding number of ordinary shares (on a fully-diluted basis) on the immediately preceding December 31, and (B) such lower number of ordinary shares as may be determined by the Committee. The Plan shall become effective on the effective date of the Company’s contemplated initial public offering is completed, which was on April 4, 2019. The grants under the Plan generally have a maximum contractual term of ten years from the date of grant. Stock option awards granted under the plan at the determination of the Board shall be effective and exercisable after the Company’ completion of IPO of its securities. The terms of individual agreements for various grants under the Plan will be determined by the Board (or its Compensation Committee) and might contain both service and performance conditions. The Company believes the options contain an explicit service condition and a performance condition. On July 2, 2020, the Board approved to amend the 2018 Plan to adjust that the maximum aggregate number of ordinary shares reserved and available pursuant to the 2018 Plan shall not at any time exceed 20% of the total number of outstanding Ordinary Shares at the time of issuance, from time to time. Such amendment was approved during shareholders’ annual meeting on July 27, 2020.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">On April 4, 2019, the Board approved to issue 1,050,500 stock options to its employees under 2018 stock option plan with exercise price of $5.0 per share.

The Black-Scholes option model requires management to make various estimates and assumptions, including expected term, expected volatility, risk-free rate, and dividend yield. The expected term represents the period of time that stock-based compensation awards granted are expected to be outstanding and is estimated based on considerations including the vesting period, contractual term and anticipated employee exercise patterns. Expected volatility is based on the historical volatility of the Company’s stock. The risk-free rate is based on the U.S. Treasury yield curve in relation to the contractual life of stock-based compensation instruments. The dividend yield assumption is based on historical patterns and future expectations for the Company dividends. For the year ended December 31, 2021, assumptions used to estimate the fair value of stock options on the grant dates are as follows:</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0;
