General Manager's speech Dear shareholders, partners, and all friends concern about Topband: Thank you for your attention and support to Topband, and I am honored to share our 2022 Annual Report with you here. In the past year, we faced many challenges, but with the joint efforts of all employees, the Company still achieved remarkable results. Our sales revenue reached RMB 8.875 billion, achieving double-digit growth and completing our annual business target. Topband has been adhering to the "long-term philosophy"; business is in the long run, not in a moment. Our mission is to advance human society by making the world a more innovative and lower-carbon place. Over the past 26 years, we have been committed to providing solutions to our customers using the "four electrics and one network" intelligent technology to create value around "intelligent" and "low carbon." In 2022, I will focus on sharing five key advances. First, a healthier business structure. We have formed a home appliance segment with household as the application scenario, a tool segment with labor as the scenario, and a new energy segment with green and low-carbon as the scenario. In 2022, the business of the new energy segment was increasing, forming a good situation of "three legs and driving side by side." Second, a richer product portfolio. Through continuous technology and product innovation, we have formed a matrix of hundreds of products covering the four core technologies of electric control, battery, motor, and power supply. We offer a range of intelligent products and solutions to help our customers and partners improve their competitiveness and achieve market success. Third, the level of intelligent manufacturing significantly improved. Under the wave of manufacturing development of "digitalization, networking, and intelligence," we have created a unique intelligent manufacturing system based on "lean," "automation," and "digitalization" to build an intelligent factory with the "shortest delivery time, stable quality, best cost, and flexible delivery." In 2022, the Company achieved a significant reduction in the overall manufacturing rate, a reduction in the manufacturing side, and a substantial increase in intelligent manufacturing. Fourth, the international layout continues to accelerate. In 2022, Vietnam and India's bases 4 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. continued to expand production, and Mexico and Romania bases were also completed and put into operation. International operation departments in Europe, America, South Africa, and Japan were established one after another, which accelerated the development of the Company's global layout. Fifth, continued improvement in organizational capacity. We further strengthen the business unit (BU) organization, delegate more resources and authority to the BU, support the BU to serve our customers better, and pull the middle and back office departments to work together through the process. In 2022, many new BU businesses increased, and organizational reforms' results gradually became apparent. Looking ahead to 2023, although there are uncertainties in the global economic situation, we believe that the development trend of "intelligent, low-carbon, and internationalization" will continue in the long term, and the Company still has excellent development opportunities. We will adhere to the value concept of "Agile-Innovation-Partnership," gain deep insight into customer needs, drive the rapid growth of new businesses and new products with innovation, and grow with our partners. In 2023, I am placing particular emphasis on three strategic priorities. First, accelerate the development of new businesses and innovative products. We have defined our future strategic emerging businesses and key innovative products through strategic planning. In 2023, we will further launch a series of particular actions around key new businesses and innovative products to focus on accelerating development. Second, accelerate international operations. The need for internationalization continues to grow as the demand for localized delivery from overseas customers increases and more Chinese companies go abroad. The Company will continue to replicate its successful experience in overseas operations, accelerate the layout of its operations in international markets and enhance its localization capabilities in markets, supply chains, and services. Third, reduce costs and increase efficiency to improve operating efficiency. Cost control is a long-term task for enterprises and a core task in the current economic environment. We will build cost advantages by strengthening design, material, and manufacturing cost reductions. At the same time, we will further optimize our organizational management and continue to carry out lean, automated, and digital improvements to continuously improve our operational efficiency through 5 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. digital operations in the supply chain, manufacturing, and operations. Looking ahead, we will implement specific work following the Company's strategic planning requirements and continue to work closely with our partners. Thanks to the trust and support of all shareholders and partners, we will continue to provide excellent products and services to our customers and build a more intelligent, low-carbon, and better future world.

Prospects for the future development of the Company (I) Social development trend and 2030 vision 1. Intellectualization 50 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. The development and application expansion of new technologies such as IOT, 5G, and AI will open up growth space and continuously accelerate the process of social intelligence. It is expected that the economic value affected by the technology will exceed USD 60 trillion by 2030.The Company will continue to explore innovative technologies in the future world and expand new opportunities for industry intelligence in various application scenarios such as clothing, food, housing and transportation, enterprises, and cities.

On the one hand, with the increasing complexity, personalization, and differentiation of terminal products, the product R&D and delivery are required to be fast, and the quality be reliable and stable. China's industrial clusters and engineer dividends have promoted the transfer of industries to China. On the other hand, with the impact of international trade conflicts, geopolitical factors, and other factors, the risk of a single Chinese industrial chain has significantly increased. Combined, the industry will gradually show a trend of mainly focusing on China and developing towards multiple regions such as Southeast Asia and North America. The Company will actively respond to new 51 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. challenges in the supply chain, expand new opportunities in multiple regions, and accelerate the pace of internationalization. 2030 vision of the Company By 2030, the Company's goal is to provide customers with intelligent solutions through deep insight into the pain points of users, scenarios, and industries, making the world smarter and low-carbon.

(II) Development strategies of the Company 1. Focusing on strategy for sustained and effective growth In 2021, based on the Company's interim development goals for 2025, a vision blueprint for the next decade was formulated, and the long-term development goals for 2030 were clearly proposed.

The Company will provide one-stop intelligent control solutions and services for the world's leading brand customers with the advantage of the "four electrics and one network" technology, especially increasing business development in the new energy industry, focusing on four main businesses of the "home appliances + tools + new energy + industry", and make good use of the capital market platform to achieve high growth in operating income scale through a combination of endogenous and extended methods. 2. Continuously enhancing innovation-driven technology and product competitiveness The Company will adhere to innovation-driven development, continuously maintain R&D investment, strengthen basic and cutting-edge technology research, construct technology control points, strengthen product line construction and create more high-quality product platforms, promote the protection of intellectual assets such 52 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. as patents and trade secrets, build technological barriers, cultivate innovative growth engines, and strengthen the cultivation of innovative talents. At the same time, the Company will seize development opportunities such as "intelligence" and "low-carbon", actively explore innovative businesses such as the Internet of Things and green commuting, consolidate and expand the core technical capabilities of the "four electrics and one network", enhance market and product development capabilities, and explore more high-value markets.

Agile operation for improving quality, reducing costs, and increasing efficiency The Company will deepen the implementation of agile operation strategy, continuously optimize business processes such as strategy, marketing, R&D, sales, purchase, and after-sales, and improve end-to-end efficiency. The Company will also increase efforts to reduce costs and increase efficiency, and comprehensively utilize various means such as R&D and design cost reduction, purchase cost reduction, and manufacturing cost reduction to achieve effective cost reduction for mature products. 4. Organizational reform and continuous evolution of process-oriented organizations Promote organizational evolution strategy, strengthen talent team building, quickly increase the number of key positions, strengthen the capacity building of the middle office and background, better empower the iron triangle team, and create a customer-centered process-oriented organization. 5. Accelerate international layout and build global multi-base delivery capabilities The Company will continue to strengthen its close customer relationship strategy. In order to meet the needs of customers for fast and nearby delivery, and in combination with business needs, the Company has established operation centers, production and manufacturing centers, R&D centers, and representative offices in multiple locations around the world. During the reporting period, the Company accelerated the gradeability of production capacity in Vietnam and India, and accelerated the construction and mass production introduction of factories in Mexico and Romania; at the same time, the Company utilized the advantages of global layout to strengthen supply chain integration and enhance local purchase capabilities. (III) Business plan of 2023 1. Realize scale growth: Based on the core technology of "four electrics and one network", continue to implement the strategy of leading customers, leverage platform advantages, and increase the share of overseas 53 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. factories to achieve scale growth in various industries, and increase the proportion of high-value products and autonomous and controllable businesses; 2.

The Company has a good credit standing, so it is able to get strong support from the bank in a timely manner. In 2023, the Company will combine its own development situation and development strategy, and make reasonable use of various capital-raising channels to raise the necessary funds for the Company's development. (V) Risks faced by the Company and countermeasures 1. External risks such as the macro environment Trade frictions and geopolitical tensions will also produce adverse influences on business confidence and investment. The Company may continue to face an uncertain external environment, so we will further strengthen risk identification and control for various businesses and regions and adjust strategies timely to minimize external influences. 2. Risks of technology upgrading The intelligent controller industry technology, as the main business of the Company, is developing rapidly with fast product upgrading and short life cycle. Although the Company continues to invest in research and development and owns a number of invention and utility patents, there is still a risk that the technology will not be updated in time to meet market demand, or lag behind competitors in launching new products, resulting in a decline in the market share and profitability of the Company. 3. Exchange rate risk 54 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. The Company's revenue from export sales accounts for more than half of total revenue. In order to cope with the risk of exchangerate fluctuation, the Company will reduce and hedge foreign exchange risks by conducting RMB hedging business, international purchase and re-pricing of new product. 4. Other risks There are many uncertainties in the current macro environment at home and abroad, and there are some factors that are unfavorable to the operation of the Company. For example, the China-United States trade war, shortage of raw materials, rising price, insufficient labor and customer credit risk will increase the uncertainty of the Company's operation. XII.

Other information includes information covered in the 2022 annual report, but does not include financial statements and our audit reports. We do not cover other information on the audit opinions issued for the financial statements, nor do we have any form of attestation conclusions on other information. In conjunction with our audit of the financial statements, our responsibility is to read other information, and in this process, consider whether other information is materially inconsistent with the financial statements or what we have learned in the audit process or it appears to be significant misstatement.

Certified public accountant's responsibility for audit of financial statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an audit report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the audit standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. 128 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd.

Meanwhile, we also execute the following works: (1) Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. Since fraud may involve collusion, forgery, intentional omission, false representation or not be subject to internal control, the risk of failure to find the significant misstatement due to fraud is higher than the risk of failure to find a major misstatement due to errors. (2) Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the internal control. (3) Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management. (4) Conclude on the appropriateness of using the going concern assumption by the management. At the same time, on the basis of the acquired audit evidence, make a conclusion whether there is a significant uncertainty in matters or circumstances that cause significant doubts about constant operational capacity of Topband. If we come to the conclusion that there are significant uncertainties, the audit guidelines require that we draw the attention of the report users to the relevant disclosures in the financial statements in the audit report; if the disclosure is not sufficient, we should issue a modified audit report. Our conclusion is based on the information that was available as of the date of the audit report. However, future events or conditions may cause Topband to discontinue operation. (5) Evaluate the overall presentation, structure and content of the financial statements and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation. (6) Obtain sufficient and appropriate audit evidence on the financial information of entities or business activities under Topband to make an audit opinion on the financial statements. We are responsible for guiding, supervising and implementing the Company's audit and bear full responsibility for the audit opinion.

We also provide a statement to governance regarding compliance with the independence-related professional ethics requirements and communicate with the governance all the relationships and other matters that may reasonably be considered to affect our independence, as well as the relevant preventive measures. In items communicated with the governance, we determine those items most important to the audit of the financial statements of the current period and constitute a key item for audit. We describe these items in the audit report unless laws and regulations prohibit the disclosure of these items, or in rare cases, the negative consequences of communicating an item in the audit report are beyond the benefits of public interest, we determine that the item should not be communicated in the audit report.

The subsequent measurement of financial assets depends on its classification. The classification of financial assets is based on the Company's business model for the management of financial assets and the cash flow characteristics of financial assets. (1) Financial assets measured at amortized cost Financial assets that meet the following conditions at the same time are classified as financial assets measured at amortized cost: the Company's business mode of managing the financial assets is to collect the contract cash flow as the target; the contract terms of the financial asset stipulate that the cash flow generated on a specific date is only the payment of principal and interest based on the amount of outstanding principal. For such financial assets, the effective interest rate method is adopted, and subsequent measurement is made at amortized cost, and the gains or losses arising from amortization or impairment are included in the current profits and losses. (2) Debt instruments investment measured at fair value with changes included in other comprehensive income Financial assets that meet the following conditions at the same time are classified as financial assets measured at fair value with their changes included in other comprehensive income: the Company's business mode of managing the financial assets aims to collect the contract cash flow and sell them; the contract terms of the financial asset stipulate that the cash flow generated on a specific date is only the payment of principal and interest based on the amount of outstanding principal. For such financial assets, fair value is adopted for subsequent measurement. The discount or premium is amortized using the effective interest rate method and recognized as interest income or expense. Except the impairment loss and the exchange difference of foreign currency monetary financial assets are recognized as the current profits and losses, the changes in the fair value of such financial assets are recognized as other comprehensive income until their accumulated gains or losses are transferred into the current profits and losses when the financial asset is derecognized. Interest income related to such financial assets is included in the current profits and losses. (3) Equity instruments investment measured at fair value with changes included in other comprehensive income 161 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. The Company irrevocably chooses to designate part of the non-tradable equity instrument investment as financial assets measured at fair value through other comprehensive income. Only the relevant dividend income is included in the current profits and losses, and the changes in fair value are recognized as other comprehensive income, until their accumulated gains or losses are transferred into retained earnings when the financial asset is derecognized. (4) Financial assets measured at fair value with changes included in the current profits and losses The financial assets other than the above financial assets measured at amortized cost and those at fair value through other comprehensive income are classified as financial assets measured at fair value with changes included in the current profits and losses. At the time of initial recognition, for the purpose of elimination or significant reduction of accounting mismatch, financial assets can be designated as those measured at fair value with changes included in the current profits and losses. For such financial assets, fair value is used for subsequent measurement, and all changes in fair value are included in the current profits and losses. If and only when the Company changes the business model for managing financial assets, it will reclassify all the affected financial assets. For the financial assets measured at fair value and whose changes are included in the current profits and losses, the relevant transaction costs are directly included in the current profits and losses, and such costs of other types of financial assets are included in the initial recognition amount. 3. Classification and measurement of financial liabilities During initial recognition, the Company's financial liabilities are classified as: "financial liabilities measured at amortization cost" and "financial liabilities measured at fair value with their changes included into the current profit and loss". Financial liabilities satisfying one of the following requirements can be designated as financial liabilities measured at fair value with their changes included in the current profit and loss during initial measurement: (1) Such designation can eliminate or remarkably reduce the accounting mismatch; (2) According to group risk management or investment strategy in the formal written documents, the management and performance evaluation of the portfolio of financial liabilities or portfolio of financial assets and financial liabilities are conducted on the basis of fair price, and within the group, it is reported to the key management personnel on such basis; (3) Such financial liabilities include embedded derivatives requiring separate splitting. The Company determines the classification of financial liabilities at the time of the initial recognition. For the financial liabilities measured at fair value with changes included in the current profits and losses, the relevant transaction costs are directly included in the current profits and losses, and such costs of other financial liabilities are included in the initial recognition amount. The subsequent measurement of financial liabilities depends on its classification: (1) Financial liabilities measured at amortized cost For such financial liabilities, the effective interest rate method is adopted and the subsequent measurement is conducted as per the amortized cost. (2) Financial liabilities measured at fair value with changes included in the current profits and losses 162 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd.

Impairment of financial assets The Company recognizes the loss provision based on the expected credit loss for the financial assets measured at the amortized cost, the debt instrument investment and financial guarantee contract measured at the fair value and whose changes are included in other comprehensive income. The term "credit loss" refers to the difference between all the contractual cash flows that the Company discounted at the original effective interest rate and received according to the contract and all the expected cash flows, i.e., the present value of all the cash shortage. Upon considering all reasonable and well-founded information (including forward-looking information), the Company estimates the expected credit impairment loss is withdrawn for "financial assets measured at amortized cost" and "financial asset (debt instruments) measured at fair value with their changes included in other comprehensive income" in single or combined manner. (1) General model of expected credit loss If the credit risk of this financial instrument has increased obviously since initial recognition, the Company will measure the loss reserves according to the expected credit loss amount of such financial instrument in the whole duration; if the credit risk of this financial instrument hasn't increased obviously since initial recognition, the Company will measure the loss reserves according to the expected credit loss amount of such financial instrument in the next 12 months. The increased or reversed amount of the loss provisions arising therefrom shall be included in the current profits and losses as impairment losses or gains. The specific assessment of credit risk by the Company is detailed in the Note "IX. Risks Associated with Financial Instruments". Generally, in case of overdue for more than 30 days, the Company will consider that the credit risk of such financial instrument has increased obviously, unless conclusive evidence is available to prove that the credit risk of such financial instrument hasn't obviously increased since the initial recognition. To be specific, the Company divides the credit impairment process of financial instruments that have not been impaired at the time of purchase or origination into three stages, with different accounting treatment for the impairment of financial instruments at different stages: First stage: credit risk has not increased significantly since initial recognition For the financial instrument at this stage, the enterprise shall measure the loss provision according to the expected credit loss in the next 12 months, and calculate the interest income as per its book balance (i.e. without deducting the impairment provision) and the actual interest rate (if the instrument is a financial asset, the same below). 163 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. Second stage: the credit risk has increased significantly since the initial recognition, but the credit impairment has not occurred For the financial instrument at this stage, the enterprise shall measure the loss provision according to the expected credit loss of the instrument thought the whole duration, and calculate the interest income as per its book balance and the actual interest rate. Third stage: credit impairment occurs after initial recognition For the financial instrument at this stage, the enterprise shall measure the loss provision according to the expected credit loss of the instrument thought the whole duration, but the calculation of interest income is different from the financial assets at the first two stages. For the financial assets with credit impairment, the enterprise shall calculate the interest income according to its amortized cost (book balance minus accrued provision for impairment, i.e. book value) and the actual interest rate. For the financial assets with credit impairment at the time of purchase or origination, the enterprise shall only recognize the change of expected credit loss in the whole duration after initial recognition as loss provision, and calculate the interest income as per its amortized cost and the effective interest rate adjusted by credit. (2) For financial instruments with low credit risk on the balance sheet date, the Company directly assumes that the credit risk of such instruments has not increased significantly since the initial recognition, while not comparing them with the credit risk at the time of initial recognition. A financial instrument may be considered to have a lower credit risk if the enterprise recognizes that the financial instruments feature low default risk, the borrower is able to fulfill its obligations to pay the contractual cash flow in the short term, and that even if there are adverse changes in economic situation and operating environment over a longer period of time, it does not necessarily reduce the borrower's ability to fulfill its obligations to pay the contractual cash flow. (3) Receivables and lease receivables The Company measures the loss provisions as per the amount of expected credit losses throughout the whole duration by the use of simplified model for expected credit loss for receivables specified in Accounting Standards for Business Enterprises No. 14 - Income, excluding significant financing components (including cases in which financing components in contracts not exceeding one year are not taken into account in accordance with the standards). The Company makes accounting policy choices to adopt a simplified model for expected credit loss, i.e., measuring the loss provisions as per the amount equivalent to the expected credit loss throughout the whole duration for receivables including significant financing components and lease receivables regulated by Accounting Standards for Business Enterprises No. 21 - Leasing. 6. Transfer of financial assets The financial assets shall be derecognized when the Company has transferred all the risks and rewords on the ownership of the financial assets to the transferee. The financial assets shall not be derecognized if the Company retains all the risks and rewards on the ownership of the financial assets. 164 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. If the Company neither transfers nor retains almost all the risks and rewards in the ownership of the financial asset, the following conditions shall be referred to: if it gives up the control over the financial asset, it shall terminate the recognition of the financial asset and recognize the assets and liabilities generated; if it does not abandon the control over the financial asset, the relevant financial assets shall be recognized according to the extent to which it continues to be involved in the transferred financial asset, and the relevant liabilities shall be recognized accordingly. If the financial guarantee is provided to the transferred financial assets to continue to be involved, the assets generated from the continued involvement shall be recognized according to the lower of the book value of the financial assets and the amount of financial guarantee. Financial guarantee amount refers to the maximum amount that will be required to be repaid out of consideration received. 11. Notes receivable The Company divides notes receivable into two portfolios of bank acceptance bills and commercial acceptance bills by type of financial instrument. With respect to bank acceptance bills, the Company considers its overdue default risk to be 0 for it has low overdue credit loss which has not significantly increased since the initial recognition, because the acceptance bank pays the payee or holder a certain amount unconditionally when the bill is due. In respect of commercial acceptance bills, the Company believes that the probability of default is correlated with the aging, and the bad debts shall be accrued according to the accounting policy of expected credit loss of accounts receivable. 12. Accounts receivable The Company measures the loss provisions as per the amount of expected credit losses throughout the whole duration by the use of simplified model for expected credit loss for receivables specified in Accounting Standards for Business Enterprises No. 14 - Income, excluding significant financing components (including cases in which financing components in contracts not exceeding one year are not taken into account in accordance with the standards). The increased or reversed amount of loss provisions generated therefrom shall be included in the current profits and losses as impairment losses or gains. The Company has implemented Accounting Standard No. 22 - Recognition and Measurement of Financial Instruments (CK [2017] No. 7) since January 1, 2019. The Company believes that the probability of default is related to the aging, which is still a mark of whether the credit risk of the Company's accounts receivable increases significantly, after it has reviewed the appropriateness of the provision for bad debts receivable in previous years based on the Company's historical bad debt losses. Therefore, credit risk loss of the Company's accounts receivable is still estimated on the basis of aging according to the original loss ratio of previous years. The accounting policies for measuring overdue credit loss of accounts receivable adopted by the Company are as follows: 1. Receivables with significant individual amount and individual provision for bad debts Significant individual amount refers to the amount of which the ending balance of individual receivables is more than RMB 1 million. 165 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. At the end of the period, a separate impairment test will be carried out on the individual receivables with significant amount. If there is objective evidence that it is impaired, the impairment loss shall be recognized with provision for bad debts according to the difference between the present value of future cash flow and the book value. 2. Receivables with provision for bad debts by portfolio The individual receivables with not significant amount at the end of the period, together with the receivables that have not been impaired after separate test, are divided into several portfolios according to the aging as the credit risk characteristics, and the impairment loss is calculated and determined according to a certain proportion of the ending balance of these receivables portfolio (the impairment test can be conducted separately), with provision for bad debts. Except for the receivables for which impairment provision has been made separately, the Company determines the proportion for following bad debt provision based on the actual loss rate of the portfolio of the same or similar receivables in previous years with the aging of receivables as the credit risk feature and in combination with the current situation: Estimated loss of accounts Estimated loss of other Aging receivable (note) receivables Within 1 year (including 1 year) 3.10% 5.00% 1-2 years (including 2 years) 9.04% 10.00% 2-3 years (including 3 years) 22.11% 30.00% 3-4 years (including 4 years) 47.51% 50.00% 4-5 years (including 5 years) 84.26% 80.00% Above 5 years 100.00% 100.00% Including: those that have been determined to be irrecoverable Write-off Write-off Note: when measuring the expected credit loss of receivables, the Company has referred to the historical experience of credit loss and adjusted it based on forward-looking estimates. 3. Receivables with not significant amount but with single provision for bad debts Reasons for individual provision for bad debts: the Company conducts a separate impairment test for the receivables with the following characteristics, although its amount is not significant. If there is objective evidence that the receivables are impaired, the impairment loss shall be recognized with provision for bad debts according to the difference between the present value of future cash flow and the book value; receivables that are in dispute with the other party or involved in litigation or arbitration; receivables that have obvious indications that the debtor is likely to be unable to perform the repayment obligation, etc. Method for bad debt provision: the impairment test shall be conducted separately. If there is objective evidence that it has been impaired, the impairment loss shall be recognized with provision for bad debts according to the difference between the present value of future cash flow and its book value. The Company measures the loss provisions as per the amount of expected credit losses throughout the whole duration by the use of simplified model for expected credit loss for receivables specified in Accounting Standards for Business Enterprises No. 14 - Income, excluding significant financing components (including cases in which 166 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. financing components in contracts not exceeding one year are not taken into account in accordance with the standards). The increased or reversed amount of loss provisions generated therefrom shall be included in the current profits and losses as impairment losses or gains. 13. Receivables financing Financial assets that meet the following conditions at the same time are classified as financial assets measured at fair value with their changes included in other comprehensive income: the Company's business mode of managing the financial assets aims to collect the contract cash flow and sell them; the contract terms of the financial asset stipulate that the cash flow generated on a specific date is only the payment of principal and interest based on the amount of outstanding principal. The receivables held by the Company transferred in the endorsed or discounted form that such transactions are frequent and involve significant amounts and the management mode aims to collect the contract cash flow and sell them in nature, are classified as financial assets measured at fair value with their changes included in other comprehensive income in accordance with the relevant provisions of the Financial Instruments Standards. 14. Other receivables Recognition method and accounting treatment method for expected credit loss of other receivables Recognition methods and accounting treatment of expected credit losses of other receivables. The Company measures the impairment loss by an amount equivalent to the expected credit loss within the next 12 months or over the entire duration, depending on whether the credit risk of other receivables has increased significantly since the initial recognition. In addition to other receivables with individual credit risk assessment, they are divided into different portfolios based on their credit risk characteristics: Portfolio name Basis for determining the portfolios Provision methods Portfolio I Risk-free portfolio This portfolio is a risk-free account. Portfolio II Aging portfolio The credit risk of the portfolio is characterized by the aging. 15. Inventories 1. Classification of inventories The inventory includes the finished products or commodities held for sale in daily activities, the unfinished products and the materials consumed in the production or in the provision of labor services, etc. 2. Pricing method of delivered inventories The delivered inventories are subject to the weighted-average system. 3. Determination basis for net realizable value of the inventory and counting and drawing method for inventory falling price reserves 167 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. On the balance sheet date, the inventories are measured at the lower of cost and net realizable value, and the inventory revaluation reserves are calculated at the difference between the cost of inventory category and the net realizable value. The net realizable value of the inventories ready for sale is determined at the estimated sale price of such inventories minus the estimated sales expenses and relevant taxes during normal production and operation, and that of the inventories to be processed is determined at the estimated sale price of the finished products minus the costs, sales expenses and relevant taxes estimated to be incurred up to completion during normal production and operation. On the balance sheet date, the net realizable values are determined separately and compared with the corresponding costs to determine the amount of withdrawal or reversal of inventory revaluation reserve if a part of inventory is subject to the contractual price agreement and the rest is not. 4. Inventory system Perpetual inventory system is the inventories. 5. Amortization method of low value consumables and packaging materials One-off write-off method is employed for both the low-value consumption goods and the packaging materials. 16. Contractual assets 1. Recognition methods and standards for the contractual assets The Company presents contractual assets or contract liabilities in the balance sheet based on the relationship between performance obligations and customer payments. The Company's right to receive consideration for goods or services transferred to customers (excluding receivables) is listed as contractual assets. 2. The recognition method and accounting treatment for expected credit loss of contractual assets The Company measures the loss provisions as per the amount of expected credit losses throughout the whole duration by the use of simplified model for expected credit loss for contractual assets excluding significant financing components. The increased or reversed amount of loss provisions generated therefrom shall be included in the current profits and losses as impairment losses or gains. The Company measures the loss provisions as per the amount of expected credit losses throughout the whole duration by the use of simplified model for expected credit loss for contractual assets including significant financing components. The increased or reversed amount of loss provisions generated therefrom shall be included in the current profits and losses as impairment losses or gains. 17. Contractual costs None 18. Assets held for sale None 168 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. 19. Debt investment None 20. Other debt investment None 21. Long-term receivables None 22. Long-term equity investment 1. Determination of investment costs (1) If the investment cost is incurred in consolidation under the same control in which case the combining party pays the combination consideration in cash, by transferring the non-cash assets, undertaking the debts or issuing the equity securities, the initial investment cost shall be determined on the basis of the share of the owner's equity of the combined party in the book value of the ultimate controlling party's consolidated financial statements on the combination date. For the difference between the initial investment cost of long-term equity investment and the book value of the consideration paid for combination or the total face value of the issued shares, the capital reserve (capital premium or share premium) shall be adjusted. If the capital reserve is insufficient to be offset, the retained earnings shall be adjusted. If a consolidation under the same control is realized step by step, the initial investment cost shall be determined on the basis of the share of the owner's equity of the combining party in book that is obtained from the combined party on the combination date and calculated at shareholding ratio. For the difference between the initial investment cost and the sum of the book value of the original long-term equity investment plus the book value of the consideration newly paid for acquiring further shares on the combination date, the capital reserve (capital premium or share premium) shall be adjusted. If the capital reserve is insufficient to be offset, the retained earnings shall be adjusted. (2) If the investment cost is incurred in the consolidation under different control, the initial investment cost shall be determined as the fair value of the consideration paid for combination on the purchase date. (3) Investment costs other than those incurred in consolidation: The initial investment cost shall be the purchase price paid actually if the investment is obtained by paying cash, the fair value of the issued equity securities if by issuing the equity securities, and the value specified in the investment contract or agreement in case of investment from an investor (unless the unfair value is specified in the contract or agreement). 2. Subsequent measurement and recognition methods for profits and losses The long-term equity investment that the Company has the control over the investee shall be calculated with cost method in its individual financial statement; those under the same control or significant influence shall be calculated with equity method. 169 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. If the cost method is applied, the long-term equity investments shall be priced at the initial investment cost. The cash dividends or profits declared to be distributed by the investee other than those that have been declared but not distributed and included in the price or consideration paid actually when the investment is obtained shall be recognized as the current investment income, and it is necessary to consider whether the long-term investment is impaired in accordance with the relevant policy of asset impairment. When the equity method is applied, if the initial investment cost of a long-term equity investment is greater than the share of fair value of identifiable net assets entitled from the investee at the time of investment, it shall be included in the initial investment cost of the long-term equity investment; otherwise, the difference shall be included in the current profits and losses and the cost of long-term equity investment shall be adjusted. When the equity method is applied, the profits and losses on investment shall be recognized and the book value of the long-term equity investment shall be adjusted according to share of the net profits and losses that shall be entitled or shared and have been realized by the investee after the long-term equity investment is obtained. When the share of the net profit and loss entitled from the investee is recognized, the proportion attributable to the investor shall be calculated at the shareholding ratio after offsetting the profits and losses of internal transactions with associated enterprises and joint ventures (full amount shall be recognized if the losses of internal transactions are the asset impairment losses) in light of the accounting policies and period of the Company on the basis of the fair value of the identifiable assets of the investee when the investment is obtained, and the net profit of the investee shall be recognized after adjustment. The portion to be distributed shall be calculated with reference to the profits or cash dividends declared to be distributed by the investee, and the book value of the long-term equity investment shall be reduced accordingly. If a net loss of the investee confirmed by the Company, the book value of the long- term equity investment, as well as other long-term equity investment which form the net investment of the investment units should be written down until zero limits, except that the Company has to undertake obligations of additional losses. The book value of the long-term equity investment was adjusted and included in the owner's equity for other changes in the owner's equity other than the net profits and losses of the investee. 3. Basis for determination of control over and significant influence on the investee Control refers to having the power over the investee, being entitled to variable returns by participating in the relevant activities of the investee and able to influence the amount of return by exercising the power over the investee. Significant influence refers to that the investor has the right to participate in decision-making in terms of the financial and operating policies of the investee but has no right to control or jointly control the formulation of these policies with other parties. 4. Disposal of long-term equity investments (1) Partial disposal of long-term equity investments into subsidiaries without loss of control The difference between the disposal price and the corresponding book value of the disposed investment shall be recognized as the current investment income in case of partial disposal of long-term equity investments into subsidiaries without loss of control. (2) Loss of control over subsidiaries due to partial disposal of long-term equity investments or other reasons 170 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. If the control over the subsidiaries is lost due to partial disposal of long-term equity investments or other reasons, the book value of the long-term equity investment corresponding to the sold equity shall be carried forward for the disposed equity, and the difference between the sales price and the book value of the disposed long- term equity investment shall be recognized as investment income (loss). In addition, the remaining equity shall be recognized as long-term equity investment or other related financial assets at its book value. The remaining equity after disposal that has joint control or significant influence on the subsidiaries shall be subject to the accounting treatment in accordance with the relevant regulations on the conversion from the cost method to the equity method. 5. Methods for impairment test and provision of impairment reserve If there is any objective evidence showing that the investments into subsidiaries, associated enterprises and joint ventures are impaired on the balance sheet date, the provision of impairment reserve shall be made accordingly based on the difference between the book value and the recoverable amount. 23. Investment property Measurement model of investment property Measurement with cost method Depreciation or amortization method 1. Investment property includes leased land use rights, land use rights held and ready to be assigned after appreciation, and leased buildings. 2. Investment property is measured initially at cost and subsequently with cost model. The provision for depreciation and amortization of the investment property are made in the way as used for fixed assets and intangible assets. If there is any sign showing that the investment property is impaired on the balance sheet date, the provision of impairment reserve shall be made accordingly based on the difference between the book value and the recoverable amount. The Company applied the cost model to subsequent measurement of investment property, and depreciated or amortized it in accordance with the policy as used for the buildings or land use rights. See V. 31."Long-term Assets Impairment" for details of the methods for impairment test and provision of impairment reserve applicable to investment property. If the real estate for private use or inventory is converted to an investment property or the investment property is converted to a real estate for private use, the book value before such conversion shall be deemed as the entry value after the conversion. If the purpose of an investment property is changed to private use, this investment property shall be converted into a fixed or intangible asset from the date of change. If the purpose of a property is changed to rent gains or capital appreciation from private use, the fixed asset or intangible asset shall be converted into an investment property from the date of change. If the purpose of a property is changed to rent gains or capital appreciation from private use, the fixed asset or intangible asset shall be converted into an investment property from the date of change. If any asset is converted into an investment property measured with the cost model, the book value before the conversion shall be deemed as the entry value after the conversion. If any asset is converted into an investment 171 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. property measured with the fair value model, the fair value on the conversion date shall be deemed as the entry value after the conversion. An investment property shall be derecognized if this investment property is disposed of or permanently retired, and it is expected that no economic benefits can be obtained from its disposal. The disposal income from the sale, transfer, scrapping or damage of an investment property shall be included in the current profits and losses after deducting its book value and relevant taxes and dues. The disposal income from the sale, transfer, scrapping or damage of an investment property shall be included in the current profits and losses after deducting its book value and relevant taxes and dues. 24.

The fixed assets under financing lease shall be recorded at the lower of the fair value of the leased assets on the start date of lease and the present value of the minimum lease payment and shall be subject to provision for depreciation in accordance with the depreciation policy of self-owned fixed assets. 25. Construction in progress 1. The construction in progress shall be transferred to fixed assets at the actual cost of the project when it is ready for use as intended. If a product under construction has been ready for use as intended but has not undergone final settlement of account, this project shall be transferred to fixed assets at the estimated value first. After final settlement of account is made, the original temporary estimated value shall be adjusted according to the actual cost without adjustment of depreciation previously accrued. 2. If there is any sign showing that a project under construction is impaired on the balance sheet date, the provision for impairment shall be made accordingly at the difference between the book value and the recoverable amount. 26. Borrowing costs 1. Recognition principle for capitalizing borrowing cost Borrowing costs occurred by the Company that may be directly attributable to the acquisition or construction of assets eligible for capitalization, are capitalized and accounted in the cost of relevant assets; while other borrowing costs are recognized as expenses and accounted into current profits and losses whenever occurred. 2.

If general borrowings are used for the purpose of purchase, construction or production of assets that meet the conditions for capitalization, the amount of interest to be capitalized shall be determined as the weighted average of asset 173 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. expenditure with accumulated asset expenditure exceeding special borrowing multiplied by capitalization rate of the general borrowing occupied. 27. Biological assets None 28. Oil and gas assets None 29. Right-of-use assets On the commencement date of the lease term, the Company recognizes the right-of-use assets and lease liabilities for the leases, except for simplified short-term leases and low-value asset leases.

If there is reasonable certainty that the lessee will obtain ownership of the leased assets when the lease term expires, the Company shall make depreciation of leased assets over their remaining service life. If it is not reasonable to be certain that the lessee will obtain the ownership of the leased assets at the expiry of the lease term, the leased assets should be calculated and withdrawn as depreciation over the shorter one of the lease term or the remaining service life. The Company determines whether the right-of-use assets are impaired in accordance with the Accounting Standards for Business Enterprises No. 8 - Asset Impairment, and carries out accounting treatment for the identified impairment losses. 174 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. 30. Intangible assets (1) Valuation method, service life and impairment test 1. Intangible assets include land usage right, software, patent rights and non-patent technologies, etc., and are initially measured at cost. 2. Intangible assets with limited service life shall be systematically and reasonably amortized according to the expected realization mode of economic benefits related within the service life, and in case the expected realization mode cannot be reliably determined, the straight-line method shall be adopted for amortization. The land usage right shall be averagely amortized within the remaining service life (generally 50 years), the software shall be averagely amortized within 3-5 years, and the patent rights and non-patent technologies within 5- 10 years. 3. In case of evidence of impairment of intangible assets with defined service life on the balance sheet date, corresponding provision for impairment shall be made according to the difference between the book value and the recoverable amount; For intangible assets with uncertain service life and intangible assets that have not reached the serviceable state, the impairment tests shall be carried out every year, whether there are signs of impairment or not. (2) Accounting policy of internal R&D expenditure Research stage expenditures of internal R&D projects shall be included in the current profits and losses at the time of occurrence.

Long-term assets impairment The enterprise shall judge whether there is any sign of possible assets impairment on the balance sheet date. Goodwill arising from consolidation and intangible assets with uncertain service life shall be tested for impairment every year, no matter whether there is any sign of impairment. In case of following signs, the assets may be impaired: (1) Market price of assets falls sharply in the current period, which is significantly higher than the expected decline due to time or normal use; (2) There are significant changes in current and future economic, technological or legal environment in which the enterprise operates and the market where assets are located, bringing adverse effects on the enterprise; (3) The market interest rate or other market return on investment has been increased in the current period, affecting the discount rate of the enterprise to calculate the present value of the expected future cash 175 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. flow of the assets and resulting in a significant decrease in the recoverable amount of the assets; (4) There exists evidence showing that the assets have become obsolete or the entity has been damaged; (5) Assets have been or will be idle, terminated or planned to be disposed in advance; (6) Evidence in the internal report of the enterprise shows that economic performance of assets has been or will be lower than the expected, for instance, the net cash flow arising from assets or the realized operating profit (or loss) is far lower (or higher) than the expected amount, etc. (7) Other indications showing that assets may have been impaired. In case of signs of assets impairment, corresponding recoverable amount shall be estimated. Recoverable amount shall be determined based on the higher of the net amount of fair value of assets minus the disposal expenses and the present value of expected future cash flow of assets. Disposal expenses include legal expenses, relevant taxes and handling fees related to disposal of assets as well as direct expenses incurred to make the assets marketable. Present value of expected future cash flow of assets shall be determined by selecting an appropriate discount rate based on the expected future cash flow generated during continuous use and final disposal of the assets.To estimate present value of future cash flow of assets, measures shall be taken to comprehensively consider factors as the expected future cash flow, service life and discount rate of the assets. In case of measurement result of recoverable amount showing that recoverable amount of the asset is lower than its book value, the book value shall be written down to the recoverable amount, and the written down amount shall be recognized as the loss of asset impairment and included in the current profits and losses; besides, corresponding provision for asset impairment shall be made at the same time. 32. Long-term deferred expenses Long-term deferred expenses shall be recorded according to the actual amount, and shall be averagely amortized in the benefit period or the specified period.

Revenue recognition The Company's revenue mainly includes sales revenue of intelligent controller, lithium battery, motor and control system. 179 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. The Company has fulfilled performance obligation in the Contract, that is, recognizing revenue when the customer obtains the control right of relevant commodities. Obtaining of the control right of relevant commodities means to be able to dominate the use of the commodities and obtain almost all economic benefits arising therefrom. 2. The Company shall judge the nature of relevant performance obligations as "performance obligations fulfilled in a certain period" or "performance obligations fulfilled at a certain time point" based on relevant provisions of revenue standards, and shall confirm revenue according to the following principles respectively. (1) In case the Company meets one of the following conditions, it shall fulfill the performance obligations within a certain period of time: ① Customers obtain and consume economic benefits arising from performance of the Company during the Company's performance of the Contract. ② Customers can control the assets under construction during the Company's performance of the Contract. ③ Assets of the Company during the performance of the Contract are irreplaceable, and the Company shall be entitled to collect money for the performance part completed so far in the whole contract period. For performance obligations fulfilled within a certain period of time, the Company shall recognize revenue according to the performance progress within that period, except that the performance progress cannot be reasonably determined. The Company shall consider the nature of commodities, and shall determine the proper performance progress by adopting the output method or the input method. (2) For performance obligations fulfilled at a certain time point rather than in a certain period, the Company shall recognize revenue at the time when customers obtain the control right of relevant commodities. When judging whether customers have obtained the control right of relevant commodities, the Company consider the following signs: ① The Company shall be entitled to immediately collect revenues from commodities, which means that customers have the obligation to pay for commodities immediately. ② The Company has transferred the legal ownership of commodities to customers, which means that customers have obtained the legal ownership of commodities. ③ The Company has transferred commodities in kind to customers, which means that customers have possessed commodities in kind. ④ The Company has transferred main risks and rewards related to the ownership of commodities to customers, which means that customers have obtained main risks and rewards related to the ownership of commodities. ⑤ Customers have accepted the commodities. ⑥ Other indications that customers have obtained the control right of commodities. The specific policies of revenue recognition of the Company are as follows: 180 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. In case the sales contract between the Company and customers has been deemed as a performance obligation fulfilled at a certain time point, the specific revenue recognition method shall be formulated according to the actual situation of the Company's product sales as follows: Domestic sales: ① The customer picks up the goods in cash. After the payment and delivery, it is considered that the customer has obtained the control of the relevant goods, and the Company has recognized the sales revenue; ② If the advance payment is used for settlement, and the other party's customer confirmation receipt is obtained after the delivery, it is considered that the customer has obtained the control of the relevant commodities, and the Company has recognized the sales revenue; ③ If the credit sale is adopted according to a certain payment period, within which the customer settles, and after the delivery, the other party's customer confirmation receipt is obtained, it is considered that the customer has obtained the control of the relevant goods, and the Company has recognized the sales revenue. Foreign sales: the Company shall deliver commodities according to the signed order, hold special export invoice, delivery note and other original documents for customs clearance and export, pass customs audit, complete export declaration procedures, obtain the customs declaration documents as the point of transfer of control of the relevant goods, and recognize the sales revenue by recording the revenue based on the delivery order, special export invoice and customs declaration form. 3. Measurement of revenue The Company shall measure revenue according to the transaction price allocated to each individual performance obligation. In determining the transaction price, the Company shall consider the influence of variable consideration, significant financing components in the Contract, non-cash consideration, consideration payable to customers as well as other factors. (1) Variable consideration The Company shall determine the best estimate of variable consideration according to the expected value or the most likely amount, but the transaction price including the variable consideration shall not exceed the accumulated recognized revenue that will not be significantly reversed when relevant uncertainty is eliminated. When evaluating whether the accumulative recognized revenue is unlikely to be significantly reversed, the enterprise shall further consider the possibility and proportion of revenue reversal. (2) Significant financing components In case of significant financing components in the Contract, the Company shall determine the transaction price according to the amount payable in cash when assuming that customers obtain the control right of commodities. Difference between the transaction price and the contract consideration shall be amortized by adopting the effective interest rate method during the contract period. (3) Non-cash consideration In case customers pay non-cash consideration, the Company shall determine the transaction price according to the fair value of the non-cash consideration. In case the fair value of non-cash consideration cannot be reasonably estimated, the Company shall indirectly determine the transaction price by referring to the separate selling price of commodities for transferring commodities to customers that it promises. 181 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. (4) Consideration payable to customers Consideration payable to customers shall be written down against the transaction price, and the current income shall be offset at the later of confirming relevant income or paying (or promising to pay) customer's consideration, except that the consideration payable to customers is to obtain other clearly distinguishable commodities from customers. In case the consideration payable by an enterprise to customers is to obtain other clearly distinguishable commodities from customers, the purchased commodities shall be confirmed in a way consistent with other purchases of the enterprise. In case the consideration payable by an enterprise to customers exceeds the fair value of a clearly distinguishable commodity obtained from the customer, the excess amount shall be used to offset the transaction price. In case the fair value of clearly distinguishable commodities obtained from customers cannot be reasonably estimated, the enterprise shall offset the transaction price with the consideration payable to customers in full.

Government subsidies calculated by adopting the gross method: (1) Government subsidies related to assets shall be recognized as deferred income and included in profits and losses by stages in a reasonable and systematic way within the service life of relevant assets. In case relevant assets are sold, transferred, scrapped or damaged prior to the end of their service life, the balance of relevant deferred income that has not been allocated shall be transferred to the profits and losses of the current period of asset disposal. (2) Government subsidies related to income and used to compensate related expenses or losses in the later period shall be recognized as deferred income, and shall be included in the current profits and losses during the period when related expenses are recognized; subsidies used to compensate relevant expenses or losses incurred shall be directly included in the current profits and losses. 4.

For discount interest of preferential policy loans to be obtained by the Company, two measures shall be adopted, including that the Ministry of Finance allocates the discount funds to the lending banks and that the Ministry of Finance allocates the discount funds to the Company: (1) In case the Ministry of Finance allocates the discount funds to the lending banks, and the lending bank provides loans to the Company at preferential policy interest rate, the Company shall choose the following methods for accounting treatment: 1) Taking the loan amount actually received as the entry value of the loan, and calculating relevant borrowing costs based on the loan principal and the preferential policy interest rate. 2) Taking the fair value of loan as the entry value, calculate the borrowing costs by adopting the effective interest rate method, and recognizing the difference between the actual received amount and the fair value of the loan as deferred income. Deferred income shall be amortized by adopted the effective interest rate method within the duration of loan to offset relevant borrowing costs. (2) In case the Ministry of Finance allocates the discount funds to the Company, the Company will write down the corresponding discount interest against relevant borrowing costs. 41. Deferred tax assets/deferred tax liabilities 1. It is required to calculate and recognize the deferred tax assets or liabilities according to the difference between the book value of the assets and liabilities and corresponding tax base (in case the tax base of items not recognized as assets and liabilities can be determined according to the provisions of the tax law, the difference between the tax base and their book amount shall be adopted) as well as the applicable tax rate during the period of expected recovery of the assets or settlement of the liabilities. 2. Recognition of deferred tax assets shall be limited to the taxable income that is likely to be obtained to offset temporary deductible differences. On the balance sheet date, if there is conclusive evidence that it is likely to obtain sufficient taxable income in the future periods to offset the deductible temporary differences, the deferred tax assets not recognized in the previous accounting periods shall be recognized. 3. The book value of deferred tax assets shall be reviewed on the balance sheet date. In case it is impossible to obtain enough taxable income to offset the benefits of the deferred tax assets in the future, the book value of the 183 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. deferred tax assets shall be written down. If it is likely to obtain enough taxable income, the write down amount shall be reversed. 4. The current income tax and deferred tax of the Company shall be recognized as income tax expense or income, and shall be included in the current profits and losses, except for income tax arising from the following circumstances: (1) consolidation; (2) transactions or matters directly recognized in the owner's equity. 42. Lease (1) Accounting treatment of operating lease 1. Lessee As the lessee, the Company recognizes the right-of-use assets and lease liabilities for the lease on the beginning date of the lease term excluding short-term leases and leases of low-value assets to which the simplified treatment applies. After the starting date of the lease term, the Company uses the cost model to make subsequent measurement of the right-of-use assets. The provision for the depreciation of the right-of-use assets shall be made with reference to the relevant depreciation provisions of the Accounting Standards for Business Enterprises No. 4 - Fixed Assets. If the lessee can reasonably determine that it will obtain the ownership of the leased assets upon the expiration of the lease term, provision for depreciation shall be made within the remaining service life of the leased assets. If it is not reasonable to be certain that the lessee will obtain the ownership of the leased assets at the expiry of the lease term, the leased assets should be calculated and withdrawn as depreciation over the shorter one of the lease term or the remaining service life. The Company determines whether the right-of-use assets are impaired in accordance with the Accounting Standards for Business Enterprises No. 8 - Asset Impairment, and carries out accounting treatment for the identified impairment losses. The Company calculates the interest expense of the lease liabilities in each period of the lease at the fixed periodic interest rate, which is included in the current profits and losses. If the cost should be included in the cost of relevant assets in accordance with the Accounting Standard for Business Enterprises No. 17 - Borrowing Costs and other standards, such provisions shall prevail. For short-term leases and low-value asset leases, the Company shall choose not to recognize right-of-use assets and lease liabilities, and include the lease payments for short-term leases and low-value asset leases in the relevant asset cost or current profit and loss according to the straight-line method during each period of the lease term. 2. Lessor During each period of the lease term, the Company as the lessor shall adopt the straight-line method to recognize the rental revenue from operating lease as rental income. The lessor shall capitalize the initial direct cost related to operating lease, and amortizes and includes such cost into the current profits and losses by installment according to the same recognition base of the rental revenue during the lease term. As for the fixed assets subject to operating leases, the Company shall calculate the depreciation of it by adopting depreciation policy for similar assets. As for other leased assets, systematic and reasonable methods shall 184 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. be adopted for its amortization according to the accounting standards for business enterprises applicable to this asset. The Company determines whether the operating lease assets are impaired in accordance with Accounting Standards for Business Enterprises, No. 8 -Asset Impairment, and carries out corresponding accounting treatment. (2) Accounting treatment of financing lease Accounting treatment of the Company as the lessee is shown in Note V 29, Note V 35 and Note V 42 (1). As the lessor, the Company shall confirm the receivable payment for financial lease on the beginning date of the lease term, terminate the recognition of financial lease assets, and calculate and recognize the interest income of each period in the lease term according to the fixed periodic interest rate. 43. Other important accounting policies and accounting estimation Hedge accounting The hedge means the risk management activity where the enterprise designates the financial instruments as the hedge instruments for the risk exposure due to the management of the specific risks such as foreign exchange risk, interest rate risk, price risk, credit risk so that the fair value or the cash flow changes, which is expected to countervail all or part of the fair value or cash flow change of the hedged projects. 1.

If the hedge meets the following conditions at the same time, the enterprise shall identify that the hedge relationship conforms to the requirements of hedge effectiveness: (a) There is the economic relationship between the hedged projects and hedge instruments. The economic relationship makes the value of the hedge instruments and hedged projects change in the reverse direction due to the same hedged risks. (b) In the value change generated for the hedged projects and hedge instruments, the effect of the credit risk is not dominant. (c) The hedge ratio of the hedge relationship shall be equal to the ratio between the hedged project quantity of the actual hedge for the enterprise and the actual quantity of the hedge instruments and shall not reflect the 185 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. unbalance of the relative weight between the hedged projects and hedge instruments, which will cause the hedge invalidation and may generate the accounting results not consistent with the hedge accounting objectives. The enterprise shall continuously evaluate whether the hedge relationship conforms to the hedge effectiveness requirements when the hedge begins and during the sequent periods, especially for the analysis of the forming reasons why it is expected to affect the hedge relationship due to the invalid part of the hedge during the residual periods of the hedge. The enterprise shall at least evaluate the hedge relationship on the day of balance sheet and when the major changes will happen for relevant situations affecting the hedge effectiveness requirements. If the hedge relationship does not conform to the hedge effectiveness requirements any more due to the hedge ratio, but the risk management objective to designate the hedge relationship does not change, the enterprise shall re- balance the hedge relationship. 3.

At the same time, the account value shall be adjusted for the confirmed hedged projects measured at the fair value. (2) Cash flow hedge If the cash flow value hedge meets the conditions to apply the hedge accounting methods, it shall be handled in accordance with the provisions below: (a) If the profit or loss generated by the hedge instrument belongs to the valid part of the hedge as the cash flow hedge reserve, it shall be incorporated into other comprehensive income. The amount of cash flow hedge reserve included in other comprehensive income in each period shall be the change amount of cash flow hedge reserve in the current period. The amount of cash flow hedge reserve included in other comprehensive income in each period shall be the change amount of cash flow hedge reserve in the current period. (b) If the profit or loss generated by the hedge instrument belongs to the invalid part of the hedge (that is, other profit or loss after deducting other comprehensive income), it shall be incorporated into the current profits and losses. (3) Net investment hedge for overseas operation As for the net investment hedge for overseas operation, including the hedge of monetary items accounting as part of net investment, it shall be handled in accordance with the provisions similar to the cash flow hedge accounting: 186 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd.

(b) If the profit or loss generated by the hedge instrument belongs to the invalid part of the hedge, it shall be incorporated into the current profits and losses. Repurchase shares If the Company or its subsidiaries shares are acquired due to the reduction of registered capital or reward of employees, the amount actually paid shall be treated as the treasury share, and the record shall be made for reference. If the repurchase shares are cancelled, the capital reserve will be offset by the difference between the total par value of the cancelled shares and the number of cancelled shares and the amount paid for the actual repurchase. If the capital reserve is insufficient to be offset, the retained earnings shall be offset; If the repurchase shares are awarded to the employees of the Company as equity-settled share-based payment, when the employees exercise the right to purchase the shares of the Company or its subsidiaries and receive the price, the cost of treasury shares delivered to the employees and the accumulated amount of capital reserve (other capital reserves) during the waiting period shall be resold, and the capital reserve (capital premium or share premium) shall be adjusted according to the difference. 44.

Risks Associated with Financial Instruments The main financial instruments of the Company include equity investment, debt investment, borrowings, accounts receivable, accounts payable, convertible bonds, etc. For details of each financial instrument, please refer to the relevant items in Note VI. The risks associated with these financial instruments and the risk management policies adopted by the Company to mitigate these risks are described below. In order to ensure all the above risks 245 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. to be controlled within a limited scope, the management of the Company has controlled and supervised the risk exposure. Sensitivity analysis technique is used for analyzing reasonableness of risk variable and possible impacts from its variation on current profits and losses or shareholder's equity. Since any risk variable rarely changes in isolation, and the correlation between the variables will have a significant effect on the final amount affected by a change in a risk variable, the following contents are based on the assumption that changes in each variable are made in isolation. The main risks arising from the Company's financial instruments include the credit risk, liquidity risk and market risk. (I) Risk management objective and policy The Company's risk management objective is to strike an appropriate balance between risks and returns, reduce the negative impact of risks on the Company's business performance to the lowest level, and maximize the interests of shareholders and other equity investors. Based on this risk management objective, the basic risk management strategy of the Company is to determine and analyze various risks faced by it, establish an appropriate risk bearing bottom line and carry out risk management, and conduct timely and reliable supervision of various risks to control risks within the limited scope. 1. Market risk (1) Foreign exchange risk Foreign exchange risk refers to the risk of loss due to exchange rate fluctuations. The Company's exposure to foreign exchange risks is mainly related to US dollars and Hong Kong dollars. Except for the Company and its subsidiary, Topband (HK) Co., Limited, which purchases and sells some materials and products in US dollars, Euros and Hong Kong dollars, TOPBAND INDIA PRIVATE LIMITED, the subsidiary, uses Indian Rupee, Topband (Vietnam) Co., Ltd. and TOPBAND SMART DONG NAI (VIETNAM)Co., Ltd., the sub-subsidiaries, use Vietnamese Dong, and Topband Germany GmbH, the sub-subsidiary, uses Euros; TOPBAND JAPAN Co., Ltd., the sub-subsidiary, uses Japanese Yen, Q.B.PTE.LTD, the sub-subsidiary, uses Singapore dollars, and TOPBAND MEXICO, S.DER.L.DEC.V., the sub-subsidiary, uses Mexican Peso; TOPBAND SMART EUROPE COMPANY LIMITED S.R.L., the grandson company, uses Romanian Leu, Tunnu Innovation HK Limited, the grandson company, uses Hong Kong dollars, and TUNNU INNOVATION, INC., the grandson company, uses US dollars; other major business activities of Topband are settled in RMB.As of December 31, 2022, the assets and liabilities of the Company are RMB balances, except that the assets or liabilities stated in VI. (LVIII) foreign currency monetary items are US dollars, Hong Kong dollars, Euros, Vietnamese Dong, Japanese Yen, Indian Rupee, Romanian Leu and Mexican Peso balances. The foreign exchange risks arising from the assets and liabilities of such foreign currency balances may have an impact on the Company's operating results. The Company pays close attention to the impact of exchange rate fluctuations on the Company's foreign exchange risks. The Company currently takes no measures to avoid foreign exchange risks. (2) Other price risks Investments held by the Company and classified as tradable financial assets are measured at fair value on the balance sheet date. Therefore, the Company is exposed to the risk of changes in the securities market. 246 Full Text of Annual Report 2022 of Shenzhen Topband Co., Ltd. 2. Credit risk On December 31, 2022, the maximum credit risk exposure causing the Company's financial losses is mainly incurred from the other party's failure to fulfill obligations, which leads the Company to financial asset losses, and financial guarantee undertaken by the Company, including confirmed carrying amounts of financial assets in consolidated balance sheets; the carrying value only reflects risk exposure of financial instruments measured at fair value rather than the maximum risk exposure, that varies with the fair value in the future. In order to reduce credit risks, the Company has set up special positions responsible for determining credit limits, conducting credit approval, and implementing other monitoring procedures to ensure that necessary measures are taken to recover overdue claims. In addition, the Company reviews the recovery of each individual receivable on each balance sheet date to ensure that adequate provision is made for uncollectible amounts. As a result, the Management of the Company believes that the credit risk assumed by the Company has been significantly reduced. The Company's working capital is deposited in a bank with a high credit rating, so the credit risk of working capital is low. The Company has adopted necessary policies to ensure that all sales customers have good credit records. The Company has no other major credit concentration risk. 3. Flow risk When managing liquidity risk, the Company maintains sufficient cash and cash equivalents as deemed by the management and monitors them to meet the Company's operational needs and reduce the impact of cash flow fluctuations. The management of the Company monitors the use of bank loans and ensures compliance with loan agreements. (II) Transfer of financial assets There were no events related to the transfer of financial assets in the Company this year. (III) Offsetting between financial assets and financial liabilities There were no events related to the offsetting between financial assets and financial liabilities in the Company this year. XI.
