Capital sources of Self-own capitals derivatives investment I. Risk analysis of forward exchange transaction The forward exchange transaction business carried out by the Company and its subsidiaries followed the principle of locking in exchange rate risk and not engaging in speculative or arbitrage trading operations. However, there were still certain risks in forward exchange transaction operations: 1. Exchange rate fluctuation risk: In the event of significant fluctuations in exchange rates, if the forward settlement exchange rate stipulated in the confirmation letter for forward exchange transactions was lower than the real-time exchange rate on the settlement day, it will cause exchange losses. 2. Internal control risk: Because forward exchange transactions are highly specialized, risks may arise due to inadequate internal control systems. 3. Customer default risk: If the customer's accounts receivable are overdue and the payment cannot be collected within the predicted payment period, it will cause a delay in forward exchange settlement and result in losses for the Company. 4. Risk of payment collection prediction: In general, the Sales Department of the Company predicts payment collection based on customer orders and expected orders. Nonetheless, during the actual execution process, customers may adjust their own orders and the Company may make an inaccurate payment prediction, leading to the risk of delayed delivery of forward exchange settlement. Risk analysis and control 5. Legal risk: Changes in relevant laws or violations of relevant legal systems by counterparties may measures of derivatives result in contracts being unable to be executed normally and cause losses to the Company. positions in the Reporting II. Risk control measures Period (including but not limited to market risk, 1. The Company has formulated the Internal Control System for Forward Exchange Transactions, which liquidity risk, credit risk, provides clear regulations on the Company's foreign exchange transaction operating principles, approval operational risk, legal risk, authority, internal operating procedures, responsible departments and individuals, information isolation etc.) measures, and risk management for forward exchange transaction, and can meet the needs of practical operations, and its internal control and risk management measures formulated are practical and effective. 2. The finance center and audit department of the Company, as relevant responsible departments, have clear management positioning and responsibilities, and responsibilities are assigned to their positions. Through this hierarchical management, the risks of single person or individual department operations are fundamentally eliminated, and the speed of risk response is also improved while effectively controlling risks. 3. To prevent delayed delivery of forward exchange transactions, the Company attaches great importance to the management of accounts receivable and actively collects accounts receivable to avoid the phenomenon of overdue accounts receivable. 4 The Company engages in financial derivative transaction business with large commercial banks with legal qualifications, closely monitors relevant laws and regulations in the field, avoiding potential legal risks. 5. The Company's forward exchange transactions must be based on a cautious prediction for foreign currency receipts (payments) of the Company, and the foreign currency amount of the foreign exchange transaction contract must not exceed 90% of the annual planned total amount of foreign currency receipts (payments).The delivery period of forward exchange transactions needs to match the Company's predicted foreign currency collection time.

(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 R&D 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 The Company's revenue from export sales accounts for nearly 60% of the total revenue. In order to cope with the risk of exchange rate 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.

IV. Other information Topband's management (hereinafter referred to as "management") is responsible for other information. Other information includes the information covered in the annual report for 2023, but does not include financial statements and our audit reports. We do not cover other information in the audit opinions issued for the financial statements, nor do we have any form of attestation conclusions on other information. 131 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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. Based on the work we have carried out, we shall report the fact if we determine the existence of a significant misstatement in other information. We have nothing to report in this regard. V. Responsibility of the management and the governance to the financial statements The management is responsible for preparing the financial statements in accordance with the provisions of the Accounting Standards for Business Enterprises to make it fair reflection, then designing, implementing and maintaining the necessary internal controls so that the financial statements do not have any significant misstatement resulting from fraud or error. When the financial statements were prepared, the management was responsible for assessing Topband's ability to continue as a going concern, disclosing the matters related to the going concern (if applicable) and applying the going concern assumption unless the management planned to conduct liquidation, terminated operation or had no other practical option. The governance level is responsible for overseeing the financial reporting process of Topband. VI. 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. As part of an audit in accordance with the audits standards, we exercise professional judgment and maintain professional scepticism throughout the audit. 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) Understand internal controls related to the audit in order to design appropriate audit procedures. (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 management. At the same time, on the basis of the acquired audit evidence, make a conclusion whether there is a significant uncertainty in 132 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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 shall 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 communicate with the governance regarding the planned scope and timing of the audit, significant audit findings and other matters, including any notable deficiencies in internal control that we identify during audit. We also provide a statement to the governance level regarding compliance with the independence-related professional ethics requirements and communicate with the governance level on all the relationships and other matters that may reasonably be considered to affect our independence, as well as relevant preventive measures. Among items discussed with the governance level, 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 shall not be communicated in the audit report. 133 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd.

Accounting treatment for consolidation under the same control and under different control 1. Accounting treatment for consolidation under the same control Assets and liabilities obtained by the Company in the consolidation under the same control realized through one transaction or multiple transactions step by step were accounted based on book value of assets and liabilities of the consolidated party in the consolidated financial statements of the final controller on consolidation date. Capital reserves shall be adjusted according to difference between the book value of net assets obtained by the Company and the payment for the book value of consolidation consideration (or total nominal value of the issued shares). If the capital reserve is insufficient to be offset, the retained earnings shall be offset. 2. Accounting treatment for consolidation under different control The Company, at the date of acquisition, recognizes the difference of the combination cost greater than the fair value share of the acquiree's net identifiable assets obtained in the combination as goodwill; if the combination cost is less than the fair value share of the acquiree's net identifiable assets obtained in the combination, the Company first re-checks the fair value of the acquiree's identifiable assets, liabilities and contingent liabilities as well as the measurement of combination cost. The difference shall be included in the current profits and losses, if the combination cost is still less than the fair value share of the acquiree's net identifiable assets obtained in the combination. The consolidation under different control realized step by step through multiple transactions shall be treated as follows: (1) Adjusting the initial investment cost of long-term equity investment. If the equity held before the acquisition date is calculated with the equity method, it shall be re-measured as per the fair value of the equity at the date of acquisition, and the difference between the fair value and its book value shall be included in the current investment income; if the equity of the acquiree held before the acquisition date involves changes in other comprehensive income and other owner's equity accounted under the equity method, it shall be transferred to the current income on the acquisition date, excluding other comprehensive income arising from changes in net liabilities or net assets of the defined benefit plan and changes in the fair value of other equity instruments held re-measured by the investee. (2) Recognizing goodwill (or amount included in the current profits and losses).The initial investment cost of long-term equity investment after the first step adjustment is compared with the fair value share of net identifiable assets of subsidiaries at the date of acquisition. If the former is greater than the latter, the difference is recognized as goodwill; otherwise, it is included in the current profits and losses. The situation of disposing equity step by step through multiple transactions to losing control over subsidiaries (1) Judging whether the transactions in the process of disposing equity step by step to losing control over subsidiaries belong to the principle of "package transaction" 155 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. The terms, conditions and economic impact of transactions relating to disposal of equity investment in subsidiaries meet one or more of the following circumstances, which generally indicates that multiple transactions shall be accounted for as a package transaction: 1) Such transactions are concluded at the same time or under the situation of considering the impact on each other; 2) Only can the unity of such transactions reach an integral commercial result; 3) The occurrence of a transaction is based on the occurrence of at least one of other transactions; 4) A transaction is regarded as uneconomic, but being economic when regarded along with other transactions. (2) Accounting treatment for transactions in the process of disposing equity step by step to losing control over subsidiaries belonging to "package transaction" If the transactions relating to disposal of equity investment in subsidiaries to losing control over subsidiaries belong to "package transaction", these shall be treated as a transaction for disposing the subsidiary and losing control; however, the difference between the price of every disposal and the net assets share held in the subsidiary corresponding to the disposal of investment before losing control shall be recognized as other consolidated income in the consolidated financial statements, which shall be transferred to the current profits and losses at the time of losing control. In the consolidated financial statements, the remaining equity shall be re-measured according to its fair value on the date of losing control. The difference between the sum of consideration obtained from equity disposal and fair value of remaining equity less the net assets share held in original subsidiary and continuously calculated from the date of acquisition as per the original shareholding ratio shall be included in the investment income of the current period of loss of control. Other comprehensive income related to the equity investment in original subsidiary shall be transferred to the current investment income or retained earnings at the time of losing control. (3) Accounting treatment for transactions in the process of disposing equity step by step to losing control over subsidiaries not belonging to "package transaction" If no loss of control occurs in the disposal of the investment in the subsidiary, the difference between the disposal price and the net assets share held in the subsidiary corresponding to the disposal of investment in the consolidated financial statements shall be included in the capital reserve (capital premium or share premium). If the capital premium is insufficient to offset, the retained earnings shall be adjusted. In case of loss of control of the investment of the subsidiary, in the consolidated financial statements, the remaining equity shall be re-measured according to its fair value on the date of losing control. The difference between the sum of consideration obtained from equity disposal and fair value of remaining equity less the net assets share held in original subsidiary and continuously calculated from the date of acquisition as per the original shareholding ratio shall be included in the investment income of the current period of loss of control. 156 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. Other comprehensive income related to the equity investment in original subsidiary shall be transferred to the current investment income or retained earnings at the time of losing control. 7. Criteria for determining control and methods for preparing consolidated financial statements The scope of consolidation of the Company's consolidated financial statements shall be determined on the basis of control. Control refers to that the Company has power over the investee, enjoys variable returns through participation in the relevant activities of the investee, and has the ability to use its power over the investee to influence the amount of its returns. Relevant activities are those activities that have a significant impact on the returns of the investee. The relevant activities of the investee shall be judged based on the specific circumstances, and usually include the sale and purchase of goods or services, the management of financial assets, the purchase and disposal of assets, research and development activities, and financing activities. The Company makes a determination as to whether it controls an investee based on a comprehensive consideration of all relevant facts and circumstances. Once changes in relevant facts and circumstances result in changes in the relevant elements involved in the definition of control, the Company will reassess. The consolidated financial statements, based on the financial statements of the parent company and its subsidiaries, are prepared by the Company in accordance with the Accounting Standards for Business Enterprises No. 33 - Consolidated Financial Statements and with reference to other relevant information. 8.

Foreign currency transaction and foreign currency statement translation 1. The translation of foreign currency transactions When foreign currency transactions are initially recognized, they are converted into RMB at the spot exchange rate on the transaction date. On the balance sheet date, foreign currency monetary items are translated at the spot exchange rate on the balance sheet date. The exchange difference arising from different exchange rates shall be included in the current profits and losses, except for the exchange difference of the principal and interest of foreign currency special borrowings related to the acquisition and construction of assets that meet the capitalization conditions; foreign currency non-monetary items measured at historical cost shall be translated at the spot exchange rate on the transaction date, with the amount in RMB maintaining unchanged; foreign currency non-monetary items measured at fair value shall be translated at the spot exchange rate on the date of determining fair value, with the difference included in the current profits and losses or other comprehensive income. 2.

When the Company becomes one party of the financial instrument contract, it shall recognize a financial asset or financial liability. The trading of financial assets in a conventional manner shall be recognized and derecognized according to the accounting of the trading day. Conventional trading of financial assets refers to the collection or delivery of financial assets within the time limit specified by laws and regulations or common practice in accordance with the terms of the contract. Trading day refers to the date when the Company promises to buy or sell financial assets. If the following conditions are met, the financial assets (or a part of financial assets, or a part of a set of similar financial assets) shall be derecognized, i.e., they shall be written off from its accounts and balance sheets: (1) The right to receive cash flow of financial assets has expired; (2) The right to receive cash flow of financial assets has been transferred, or the Company has assumed the obligation to timely pay the full amount of the cash flow received to a third party under the "transfer agreement"; and (a) has transferred substantially all the risks and rewards from the ownership of financial assets, or (b) abandoned the control of the financial asset, though almost all risks and rewards from the ownership of the financial asset are neither transferred nor retained. 2. Classification and measurement of financial assets At the time of initial recognition, the financial assets of the Company are classified according to the Company's business model for the management of financial assets and the contractual cash flow characteristics of financial assets as follows: financial assets measured at amortized cost, financial assets measured at fair value through other comprehensive income, and financial assets measured at fair value through current profits and losses. 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 159 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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 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 160 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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 Such financial liabilities include tradable financial liabilities (including derivatives that belong to financial liabilities) and financial liabilities designated upon initial recognition as those measured at fair value with changes included in the current profits or losses. 4. Set off of financial instruments If the following conditions are met at the same time, financial assets and financial liabilities are presented in the balance sheet at the net amount after offsetting each other: the Company has the legal right to offset the recognized amount, which is currently enforceable; they plan to settle at the net amount, or realize the financial assets and pay off the financial liabilities at the same time. 5. 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 161 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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 "XI. 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 provision for impairment) and the actual interest rate (if the instrument is a financial asset, the same below). 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) 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 162 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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 rewards 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. 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. 12. 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. 13. 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 163 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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. 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 provision for impairment 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: Aging Estimated loss of accounts Estimated loss of other 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 164 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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 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. 14. 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. 15. 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: 165 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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. 16. Contract 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 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 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. 17. 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. Inventory system Perpetual inventory system is the inventories. 4. Amortization method of low-value consumables and packaging materials One-off write-off method is employed for both the low-value consumables and the packaging materials. 5. Recognition criteria and provision method for inventory revaluation reserve 166 Full Text of Annual Report 2023 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. 18. Assets held for sale 1. Recognition criteria and accounting treatment for non-current assets or disposal groups classified as held for sale The Company classifies group components (or non-current assets) as held for sale if they meet all of the following conditions: (1) they are readily available for sale in their current state based on the practice of selling such assets or disposal groups in similar transactions; and (2) it is highly likely that a sale will occur, a resolution has been made on a sale plan, and a firm purchase commitment has been obtained (a firm purchase commitment refers to a legally binding purchase agreement signed between an enterprise and another party, which contains important terms such as transaction price, time, and sufficiently severe penalty for breach of contract, so that the possibility of significant adjustment or cancellation of the agreement is extremely small).The sale is expected to be completed within one year. The approval required by relevant authorities or regulatory departments has been obtained in accordance with relevant regulations. The Company adjusts the estimated net residual value of assets held for sale to reflect the net amount of its fair value less selling expenses (but not exceeding the original book value of the asset held for sale). The difference between the original book value and the adjusted estimated net residual value is recorded in the current profit and loss as an asset impairment loss, and a provision for asset impairment held for sale is made at the same time. The amount of asset impairment loss recognized for a disposal group held for sale shall first be offset against the carrying amount of goodwill in the disposal group, and then the carrying amount of each non- current asset in the disposal group that is subject to the measurement requirements of the Criteria shall be offset in proportion to its share. If the net amount of the fair value of non-current assets held for sale less selling expenses increases on subsequent balance sheet dates, the amount previously written down shall be restored and reversed within the amount of the asset impairment loss recognized after classification as held for sale, and the reversed amount shall be included in the current profit and loss. Impairment losses recognized before the asset is classified as held for sale shall not be reversed. If the net amount of the fair value of a disposal group held for sale less selling expenses increases on subsequent balance sheet dates, the amount previously written down shall be 167 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. restored and reversed within the amount of the asset impairment loss recognized for non-current assets in accordance with the measurement requirements of the Criteria after classification as held for sale, and the reversed amount shall be included in the current profit and loss. The carrying amount of goodwill that has been written off and the impairment losses on non-current assets subject to the measurement requirements of the Criteria recognized before they are classified as held for sale shall not be reversed. The amount of subsequent reversal of impairment losses recognized by a disposal group held for sale shall be increased in proportion to the carrying amounts of various non-current assets in the disposal group that are subject to the measurement requirements of the Standard, except goodwill. If an enterprise loses control over a subsidiary due to sales of its investment in the subsidiary or other reasons, regardless of whether the enterprise retains part of the equity investment after the sale, it shall classify the investment in the subsidiary as a whole as held for sale in the parent company's individual financial statements and classify all assets and liabilities of the subsidiary as held for sale in the consolidated financial statements when the investment in the subsidiary to be sold meets the conditions for classification as held for sale. 2. Criteria for determining and reporting discontinued operations Discontinued operations refer to separately identifiable components of an enterprise that meet any of the following conditions and have been disposed of or classified as held for sale: (1) the component represents an independent major business or a separate major operating area; (2) the component is part of a related plan to dispose of an independent major business or a separate major operating area; or (3) the component is a subsidiary acquired specifically for resale. The definition of discontinued operations includes the following three aspects: (1) The discontinued operations shall be a separately identifiable component of the enterprise. The operations and cash flows of this component can be clearly distinguished from other parts of the enterprise when the enterprise is operated and the financial statements are prepared. (2) The discontinued operations must be of a certain scale. The discontinued operations shall represent a separate principal business or a separate major operating area, or be part of a related plan to dispose of a separate principal business or a separate major operating area. (3) The discontinued operations must meet certain timing requirements. A component that meets the definition of discontinued operations shall fall into one of the following two situations: the component has been disposed of before the balance sheet date, including being sold and discontinued (such as shut down or scrapped); the component has been classified as held for sale before the balance sheet date. 19. Debt investment None. 20. Other debt investment None. 168 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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. 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. 169 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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 shall 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 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 170 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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.

See Note III. (XXIII). "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.

Accounting policies adopted for revenue recognition and measurement (1) Revenue recognition The Company's revenue mainly includes sales revenue of intelligent controller, lithium battery, motor and control system. 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. 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. 178 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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 considers 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. (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 179 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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. 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. 2. The specific policies of revenue recognition of the Company are as follows: 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. The same type of business adopting different operating models involving different revenue recognition methods and measurement methods None. 180 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 38. Contractual costs Contractual costs are divided into contract performance costs and contract acquisition costs. The costs incurred by the Company to perform a contract shall be recognized as an asset as contract performance costs if the following conditions are met at the same time: 1. The costs are directly related to a current or anticipated contract, including direct labor, direct materials, manufacturing overhead (or similar costs), costs clearly borne by the client, and other costs incurred solely for the contract; 2. The cost increases the resources that the enterprise will use to fulfill its performance obligations in the future; 3. The costs are expected to be recovered. The Company recognizes the incremental costs incurred to obtain a contract as an asset if it expects to recover the incremental costs incurred to obtain the contract; however, if the asset is amortized for no more than one year, it may be included in the current profit and loss when incurred. Assets related to contractual costs are amortized on the same basis as revenue from goods or services related to the asset. If the carrying amount of an asset related to contractual costs exceeds the difference between the following two items, the Company will make an provision for impairment for the excess and recognize it as an asset impairment loss: 1. The remaining consideration expected to be obtained from the transfer of goods or services related to the asset; 2.

Government subsidies calculated by adopting the gross method: 181 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. (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. Government subsidies calculated by adopting the net method: (1) Government subsidies related to assets shall be used to offset the book value of relevant assets; (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 used to offset related costs when related expenses are recognized; subsidies used to compensate relevant expenses or losses incurred shall be directly used to offset related costs. 5.

Deferred income shall be amortized by adopted the effective interest rate method within the duration of loan to offset relevant borrowing costs. 182 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. (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. 40. 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 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. 41. Lease (1) Accounting treatment of lease as the 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 shall 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 183 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 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 shall be included in the cost of relevant assets in accordance with the Accounting Standards 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) Accounting treatment of lease as the 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 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. 42. Other important accounting policies and accounting estimation 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. 184 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 43.

In order to ensure all the above risks 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 shareholders' 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.

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 252 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. EUROPE COMPANY LIMITED S.R.L., the sub-subsidiary, uses Romanian Leu, Tunnu Innovation HK Limited, the sub-subsidiary, uses Hong Kong dollars, and TUNNU INNOVATION, INC., the sub-subsidiary, uses US dollars; other major business activities of the Company are settled in RMB.As of December 31, 2023, the assets and liabilities of the Company are RMB balances, except that the assets or liabilities stated in VI. (LIX) foreign currency monetary items are US dollars, Hong Kong dollars, Euros, Vietnamese Dong, Japanese Yen, Indian Rupee, Romanian Leu and Mexican Peso balances, Rand and Canadian dollars. 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. 2. Credit risk On December 31, 2023, 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. 253 Full Text of Annual Report 2023 of Shenzhen Topband Co., Ltd. 3. Liquidity 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. (III) Transfer of financial assets There were no events related to the transfer of financial assets in the Company this year.
