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 100 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 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 101 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 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 and 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 102 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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. For details about specific assessment of credit risks by the Company, refer to 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 103 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 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. 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 104 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 its risk of overdue credit loss is low and 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 bad debts shall be accrued for the expected credit loss of accounts receivables according to the accounting policy. 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 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, and reviewed the appropriateness of the provisions for bad debts receivables in previous years based on the Company's historical impairment losses on bad debt provision. 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. Therefore, the credit risk loss of the Company on accounts receivables is still estimated on the basis of aging according to the original loss ratio of the previous years. The accounting policies for measuring overdue credit loss of accounts receivable adopted by the Company are as 105 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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: 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 Write-off Write-off be irrecoverable Note: When measuring the expected credit loss of account 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 106 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 accounts receivable 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 107 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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. 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 For contract assets without material financing components (including cases in which financing components in contracts not exceeding one year are not taken into account in accordance with the standards) as specified in the Accounting Standards for Business Enterprises No. 14 - Income, the Company measures provisions for losses as per the amount of expected credit losses throughout the whole duration by using a simplified model for the expected credit loss. The increased or reversed amount of loss provisions generated therefrom shall be credited to the current profits and losses as impairment losses or gains. For contract assets with material financing components, the Company measures provisions for losses as per the amount of expected credit losses throughout the whole duration by using a simplified model for the expected credit loss. 17. Inventory 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 108 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. The delivered inventories are subject to the weighted-average system. 3. Inventory system Perpetual inventory system is the inventories. 4. Amortization 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. Determination criteria and accrual method of provision for impairment on inventories On the balance sheet date, inventories are measured at the lower of cost and net realizable value, and provisions of impairment on inventories are accrued with the difference between the cost of single inventory and 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 selling 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, selling 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. Determination criteria and accounting treatment of non-current assets or disposal group classified as held for sale The Company classifies the group components (or non-current assets) as holding for sale if both of the following conditions are met: (1) in accordance with the practice of selling such assets or disposal groups in similar transactions, they can be sold immediately under current conditions; (2) the sale is highly likely to occur, a sale plan has been agreed upon and a firm purchase commitment has been obtained (a firm purchase commitment is a legally binding purchase agreement between the enterprise and other parties that contains the major terms concerning the price and time of transaction, severe enough penalties for breach of contract, etc. that make it highly unlikely that the agreement will be materially adjusted or cancellation). It is expected the sale will be completed within one year. It has been approved by relevant authorities or regulatory authorities in accordance with relevant provisions. The Company adjusts the estimated net residual value of assets held for sale to a net amount reflecting its fair value less selling expenses (but shall not exceed the original carrying value of the assets held for sale), the difference 109 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. between the original carrying value and the adjusted estimated net residual value is credited to the current profit and loss as an asset impairment loss, and at the same time, a provision for impairment is made for the assets held for sale. For the amount of asset impairment losses recognized for the disposal group held for sale, the carrying value of goodwill in the disposal group shall be offset first, and then the carrying value shall be offset proportionally according to the proportion of the carrying value of each non-current asset in the disposal group applicable to the measurement provisions of the standard. If the net amount of the fair value of the non-current assets held for sale less the selling expenses increases on the subsequent balance sheet date, the amount previously written down shall be restored and reversed below the amount of asset impairment losses recognized after the assets are classified as holding for sale, and the amount reversed shall be credited to the current profits and losses. Impairment losses on assets recognized before they are classified as holding for sale cannot be reversed. If the net amount of the fair value of the disposal group held for sale less the selling expenses increases on the subsequent balance sheet date, the amount previously written down shall be restored and reversed below the amount of asset impairment losses recognized for the non-current assets applicable to the measurement provisions of the standard after the assets are classified as holding for sale, and the amount reversed shall be credited to the current profits and losses. The carrying value of goodwill that has been written off and the asset impairment losses recognized before the non-current assets are classified as holding for sale under the measurement provisions of the standard cannot be reversed. For the subsequent reversed amount of asset impairment losses recognized for the disposal group held for sale, the carrying value shall be increased proportionally according to the proportion of the carrying value of each non-current asset in the disposal group applicable to the measurement provisions of the standard, except goodwill. If an enterprise loses its control over a subsidiary due to the sale of its investment in the subsidiary, regardless of whether the enterprise retains part of the equity investment after the sale, it shall, when the investment in the subsidiary to be sold meets the classification conditions for holding for sale, classify the investment in the subsidiary as a whole as holding for sale in the individual financial statements of the parent company, and classify all assets and liabilities of the subsidiary as holding for sale in the consolidated financial statements. 2. Determination criteria and presentation of discontinued operations Discontinued operations refer to a separable component of the enterprise that meets one of the following conditions and has been disposed of or classified as holding for sale: (1) the component represents a separate principal business or a separate principal operating region; (2) the component is part of an associated plan 110 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. concerning the disposal of a separate principal business or a separate principal operating region; (3) the component is a subsidiary acquired exclusively for resale. The definition of discontinued operations includes the following three meanings: (1) The discontinued operations shall be a component that can be separated by the enterprise. The operation and cash flows of this component can be clearly distinguished from the other components of the enterprise in its operation and in the preparation of financial statements. (2) The discontinued operations shall have a certain scale. The discontinued operations shall represent a separate principal business or a separate principal operating region, or part of an associated plan concerning the disposal of a separate principal business or a separate principal operating region. (3) The discontinued operations shall satisfy the given time requirement. A component that meets the definition of discontinued operations shall be in one of two situations, i.e. the component has been disposed of before the balance sheet date, including having been sold and discontinued (e.g. closure or scrapping); this component has been classified as holding for sale prior to the balance sheet date. 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 111 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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. 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. 112 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 113 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 for 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 for 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 for impairment reserve shall be made accordingly based on the difference between the book value and the recoverable amount. See Note III. (23)"Long-term Assets Impairment" for details about the methods for impairment testing and provision for impairment applicable to investment properties. 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 114 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 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. Fixed assets (1) Conditions for recognition Fixed assets refer to the tangible assets that are held for production of goods, provision of labor services, lease or operation management and of which the service life exceeds one fiscal year. (2) Depreciation method Annual depreciation Type Depreciation method Depreciable life Residual rate, % rate, % Houses and buildings Straight-line method 20-40 years 5 2.375-4.75 Machinery and Straight-line method 10 years 5 9.50 equipment Transportation Straight-line method 5 years 5 19.00 equipment Tooling Straight-line method 5 years 5 19.00 Electronic equipment Straight-line method 5 years 5 19.00 and other equipment 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 115 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 construction in progress 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. Capitalization period of borrowing costs (1) The borrowing costs shall be capitalized if they meet the following conditions: 1) Asset expenditures have been incurred; 2) Borrowing costs have been incurred; 3) Acquisition, construction or production activities necessary for the assets to reach the usable or marketable state as intended have begun. (2) The capitalization of borrowing costs shall be discontinued if the acquisition, construction or production of an asset that meets the conditions for capitalization is abnormally interrupted for more than 3 successive months. The borrowing costs incurred during the period of interruption shall be recognized as current expenses until the acquisition, construction or production of assets is resumed. (3) The capitalization of borrowing costs shall cease when the purchased, constructed or produced assets that meet the conditions for capitalization reaches the intended usable or marketable state. 3. Capitalized amount of borrowing costs If special borrowings are 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 interest expenses actually incurred (including the amortization of discounts or premiums determined with the effective interest rate method) in the current period of the special borrowing minus the interest income from the unused borrowings that have been deposited in the bank or the profit from temporary investment by the unused borrowings. 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 expenditure with accumulated asset expenditure exceeding special borrowing multiplied by capitalization rate of 116 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. the general borrowing occupied. 27. Biological assets None. 28. Oil and gas assets None. 29. Intangible assets (1) Service life and its determination criteria, estimation, amortization method or review procedure 1. The intangible assets of the Company, including land use rights, software, patent rights and non-patented technologies, are initially measured at cost. 2.

Accounting policies applied 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 determines 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 recognizes revenues according to the following principles respectively. When the Company meets one of the following conditions, it shall be performance obligations fulfilled in a certain period: 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 122 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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. For performance obligations fulfilled at a certain time point rather than in a certain period, the Company recognizes revenues 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. (3) Revenue measurement 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, and consideration payable to customers as well as other factors. ① Variable consideration The Company determines the optimal estimation of variable considerations based on the expected value or the most likely amount, but the transaction price including the variable consideration shall not exceed an amount that is highly unlikely to result in a material reversal of cumulative recognized revenue when the 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 123 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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. 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 Company. 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. Specific policies of the Company for revenue recognition 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 advances received are 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 124 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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. Different revenue recognition and measurement methods for similar businesses using different operation modes None. 38. Contract cost Contract cost is divided into contract performance cost and contract acquisition cost. The cost incurred by the enterprises of the Company for contract performance shall be deemed as a contract performance cost and recognized as an asset if the following conditions are met: 1. The cost is directly related to a current contract or a contract expected to be acquired, including direct labor cost, direct material cost, manufacturing (or similar) cost, cost clearly stated to be borne by the customer, and other costs incurred only as a result of the contract; 2. The cost requires enterprises to use more resources to perform the obligation in the future; 3. The cost is expected to be recoverable. When an incremental cost incurred by the Company for acquiring a contract is expected to be recovered, it shall be treated as a contract acquisition cost and recognized as an asset; however, if the asset is amortized for less than one year, it can be credited to the current profits and losses when incurred. Assets related to contract costs are amortized on the same basis as the recognition of revenue of goods or services related to that asset. If the carrying value of an asset related to the contract cost is higher than the difference between the following two items, the Company will make a provision for impairment for the excess and recognize it as an asset impairment loss: 125 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 1. Remaining consideration expected to be obtained as a result of the transfer of goods or services related to the asset; 2. Cost estimated to be incurred for the transfer of the relevant goods or services. In case of reversal of the above provision for impairment of assets, the carrying value of the asset shall not be higher than its book value on the reversal date when the provision for impairment would have not been accrued. 39. Government subsidies 1. Government subsidies include government subsidies related to assets and government subsidies related to income. 2. In case the government subsidies can be included in monetary assets, they shall be measured according to the amount received or receivable; In case the government subsidies can be classified as non-monetary assets, they shall be measured at fair value, and once the fair value cannot be obtained reliably, they shall be measured in nominal amount. 3. 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. 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. For government subsidies that contain both a part related to assets and a part related to income, separate the 126 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. different parts for accounting treatment; if indistinguishable, classify such subsidies as income-related government subsidies as a whole. 6. The government subsidies related to the daily activities of the Company shall be included into other incomes or used to write down related costs and expenses in accordance with the essence of economic operations; the government subsidies independent of the daily activities shall be included into the non-operating income and expense. 7. 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. 40. Deferred income tax assets/deferred income 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 127 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 for leases as a 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 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. 128 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 for leases as a 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 Share repurchase 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. 129 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 43.

XII. Risks related to financial instruments 1. Various risks from 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 to be controlled within a limited scope, the management of the Company has controlled and supervised the risk exposure. 199 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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. 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 risk management of the Company is intended to achieve an appropriate balance between risks and returns, mitigate the negative impact of risks on the Company's business performance to minimum, 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 (Hong Kong) Co., Ltd. that purchase and sell some materials and products in US dollars, Euros and Hong Kong dollars, its subsidiary TOPBAND INDIA PRIVATE LIMITED that uses Indian Rupee, its sub- subsidiary TOPBAND SMART DONG NAI (VIETNAM) Co., Ltd that use Vietnamese Dong, its sub-subsidiary Topband Germany GmbH that uses Euros, its sub-subsidiary TOPBAND JAPAN Co., Ltd. that uses Japanese Yen, its sub-subsidiary Q.B.PTE.LTD that uses Singapore dollars, its sub-subsidiary TOPBAND MEXICO, S.DER.L.DEC.V. that uses Mexican Peso, its sub-subsidiary TOPBAND SMART EUROPE COMPANY LIMITED S.R.L. that uses Romanian Leu, its sub-subsidiary Tunnu Innovation (Hong Kong) Limited that uses Hong Kong dollars, its sub-subsidiary TUNNU INNOVATION, INC that uses US dollars, and its sub-subsidiary YOLANESS AFRICA (PTY) LTD that uses Rand as the settlement currency, other major business activities of the Company are settled in Chinese Yuan. As of June 30, 2024, the balances of assets and liabilities of the Company are in Chinese Yuan, except the balances of assets or liabilities stated in VII. (81) foreign currency monetary items are in US dollars, Hong Kong dollars, Euros, Vietnamese Dong, Japanese Yen, Indian Rupee, Romanian Leu, Mexican Peso, Rand 200 Full Text of the Semi-annual Report 2024 of Shenzhen Topband Co., Ltd. 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 As of June 30, 2024, the maximum credit risk exposure that may cause financial losses to the Company was mainly due to a failure of the other party to fulfill obligations, which led to financial asset losses to the Company, and financial guarantee undertaken by the Company, including recognized carrying amounts of financial assets in consolidated balance sheets; for financial instruments measured at the fair value, the carrying value only reflects its risk exposure, rather than the maximum risk exposure that varies with the fair value in the future. In order to reduce credit risks, the Company has arranged special positions responsible for determining credit limits, conducting credit review and 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.
