Main business analysis In the first half of 2022, the pandemic in many places in China repeated. In the first quarter, two waves of pandemics occurred in Shiyan Sub-district, Bao'an District, Shenzhen, where the Company's headquarters is located, affecting the production and operation to a certain extent. In the second quarter, the pandemic in Shanghai and its surrounding areas had a wider impact on customers in the Yangtze River Delta and on the semiconductor supply to varying degrees. Under the background of the state's policy of "Adopting vigorous measures to prevent import of cases and resurgence of infections" and implementing the scientific, accurate and dynamic zero-COVID policy, the Company's production and operation faced many external challenges, such as multiple difficulties in transportation, personnel, and materials. During the reporting period, all employees of the Company united sincerely, took the initiative and did their best to organize the resumption of work and production under the premise of ensuring safety. We took advantage of the production capacity layout in many places in China and overseas factories, to ensure the timely delivery of customer orders to the greatest extent by optimizing the allocation of production capacity and increasing the stocking of scarce materials. With the joint efforts of all Topband staff, the Company achieved operating incomes of 4.228 billion yuan during the reporting period, a year-on-year increase of 16.02%, and net profits of 247 million yuan attributable to shareholders of the listed companies, a year-on-year decrease of 42.43%, and net profits of 205 million yuan attributable to shareholders of the listed companies after deduction of non-recurring profits and losses, a year-on- year decrease of 35.99%. Among them, various indicators such as revenue and profit in the second quarter have been significantly improved compared with the first quarter. In the second quarter, the operating incomes increased by 26.37% from the previous quarter, and the net profit attributable to shareholders of the listed companies after deduction of non-recurring gains and losses reached 147 million yuan, an increase of 155% from the first quarter. (I) During the reporting period, the operating income was 4.228 billion yuan, a year-on-year increase of 16.02%. The main reasons are as follows: The future belongs to an intelligent society, and all walks of life need controllers for people's necessities. Secondly, the intelligent control industry is showing a trend of focusing on the head companies and transferring to a professional third party. During the reporting period, due to the impact of the pandemic, the Russian-Ukrainian war and the year-on-year base, the growth rate of the basic business (home appliances and tool units) slowed down. As the Company's growth business, the new energy unit achieved rapid growth. Overseas business progressed smoothly, and the proportion of export revenue increased to over 60% during the reporting period. New 14 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. breakthroughs were made in each business segment in terms of product categories and customers. The business development in the first half of 2022 is as follows: (1) Tool unit: the Company's basic business unit. In the first half of 2022, the sales revenue reached 1.607 billion yuan, a year-on-year increase of 7.96%. The Company reserved a relatively rich product line in this unit, providing downstream customers with one-stop solutions covering controllers, motors, BMS, battery packs and complete machines. The focus of tool unit was mainly on power tools and garden tools, with a high downstream concentration. The world's top ten complete machine customers occupied the main market share, and companies from Europe and the United States accounted for a relatively high market share in the terminal market. During the reporting period, affected by the economic prosperity of Europe and the United States, the growth rate slowed down. In the medium and long term, the application scenarios of tools are increasing, and there is still plenty of room for improving the penetration rate in markets other than Europe and the United States. The industry will not change its continuous growth trend due to short-term factors such as the pandemic. With the increase in the rate of lithium battery and cordless application, and the increase in the volume of product platforms and leading customers, the Company's market share in this unit will further increase. (2) Home appliance unit: the Company's basic business unit. In the first half of 2022, the sales revenue reached 1.515 billion yuan, a year-on-year increase of 12.1%. The main reasons included the smooth development of big customers, the increase of the number and volume of customers,and the constant emergence of innovative products, e.g. the rapid growth of innovative intelligent devices, commercial air conditioning,frequency conversion air conditioning,kitchen appliances, purification products and service robots which opened up the growth space of the home appliance unit. For the traditional business, the Company will strengthen the ability to gain insight into market opportunities, deeply understand customer needs, improve its resource integration ability and internal operational efficiency, and strive for more orders to ensure its scale advantages. For innovative business, we will make use of the core advantages of technological innovation to incubate and market innovative products continuously so as to achieve both commercial success and rapid growth. (3) New energy unit: The Company's growth business. In the first half of 2022, the sales revenue reached 858 million yuan, a year-on-year increase of 61.23%. Focusing on energy storage, green commuting and other fields, the unit is higher than the overall growth rate of the Company. The Company's new energy business has rich product lines and diverse product forms. In the field of new energy, we can provide solutions for inverters, cells, battery management systems, battery packs, battery swap cabinets, PACK and other products and complete systems. 15 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. Relying on years of technology accumulation and stable quality assurance, we can open the market quickly with the advantages of customized solutions. Due to the historical industry opportunity of low carbon plus the overseas energy shortage caused by war and severe weather, the overseas market demand for energy and household energy storage is rather strong in the first half of 2022, and it is expected thatthe trend of high growth will continue. (4) Industrial unit: In the first half of 2022, the sales revenue reached 135 million yuan, a year-on-year decrease of 18.82%. The Company mainly provides controllers, drives and motors for downstream automation equipment customers, which are widely used in 3C electronics, robots, medical device, photovoltaic equipment, semiconductor equipment, textile machinery, packaging machinery, etc. During the reporting period, the economic situation and pandemic had a certain impact on the demand of industrial automation industry. By adopting the strategy of focusing on key industries and key customers, the Company made breakthroughs in photovoltaic industries and other industries, with a small year-on-year growth of servo products. We are committed to helping automation equipment manufacturers improve equipment design performance, reduce equipment manufacturing costs, and speed up the development of new equipment. Benefiting from domestic substitutions and intelligent upgrading of factories, the unit will usher in a new boom cycle in the future. (5) Intelligent solutions: The intelligent solution is the integrated solution of "innovative products + AIoT platform + customized service" for the "clothing, food, housing and transportation", "industry, catering, hotel, and park" and other scenarios with the Company's AIoT (Artificial Intelligence of Things) technology platform and intelligent product innovation capabilities as the core. In the first half of 2022, the sales revenue reached 83 million yuan, a year-on-year increase of 5.04%. (II) During the reporting period, the net profits attributable to shareholders of the listed companies after deduction of non-recurring gains and losses reached 205 million yuan, a year-on-year decrease of 35.99%. The main reasons are as follows: 1. Supply-side impact: Material cost was an important part of the Company's main business cost. In 2021, due to the pandemic and other external influences, the cost of raw materials such as chips had risen sharply, and gradually stabilized in the first half of 2022, but the prices of imported semiconductors and transistors were at high level, without significant drop. In the first half of 2022, the external environment was turbulent. In order to ensure the safety of delivery, the Company reserved a certain amount of inventories, consumed some high-priced inventories in the second quarter and counted them into cost accordingly. During the reporting period, the integrated gross margin of products was 19.08%, an increase of 0.07 percentage points from the previous quarter and a year- 16 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. on-year decrease of 5.04 percentage points. 2. Influence of equity incentive expenses: During the reporting period, the accrued equity incentive expenses increased by approximately 71 million yuan on a year-on-year basis. 3. Three period expenses (selling expenses, R&D expenses and management expenses): After the deduction of equity incentive expenses, the three expenses increased by about 150 million yuan year-on-year. The main reasons were that the Company's business was in a period of rapid development, requiring more R&D Investments on new projects. Meanwhile, under the development strategy of multi-regionalization and close customer relationship, overseas bases such as Romania and Mexico were still in the early stage of investment, as a result, selling expenses increased year-on-year. With the promotion of these strategies, the ability to serve customers nearby can be improved, and the impact of political risks such as trade wars and the pandemic on company operation can be also reduced. (III) During the reporting period, the net profits attributable to shareholders of the listed companies reached 247 million yuan, a year-on-year decrease of 42.43%. The main reasons are as follows: In addition to the above factors affecting the net profits attributable to shareholders of the listed companies after deduction of non-recurring gains and losses, the gain from fair value changes from external investment during the reporting period decreased by approximately 65 million yuan year-on-year. Year-on-year changes in key financial data Unit: yuan Year-on- This reporting Same period last year Reasons for change period year increase or decrease Compared with the same period of last year, it increased by 583.96 million yuan or 16.02% during the reporting Operating 4,228,003,137.57 3,644,045,612.40 16.02% period.

Recognition and derecognition of financial instruments 88 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. The Company recognizes a financial asset or financial liability when it becomes a party to a financial instrument contract. 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 satisfying the following conditions at the same time are classified as financial assets measured at amortized cost: The business model for managing such financial assets by the Company is to collect contractual cash flows as the goal; the contract terms of the financial assets stipulate that the cash flow generated on a specific date is only the payment of the principal and the interest based on the outstanding principal amount. 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. 89 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. 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 through other comprehensive income: The business model for managing the financial assets by the Company is to collect contractual cash flows and to sell financial assets; The contract terms of the financial asset stipulate that the cash flow generated on a specific date is only the payment of the principal and the interest based on the outstanding principal amount. 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. 90 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. 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 The financial liabilities of the Company are classified at the initial recognition as follows: financial liabilities measured at amortized cost and financial liabilities measured at fair value through current profits and losses. Financial liabilities that meet one of the following conditions can be designated as financial liabilities measured at fair value through current profits and losses at the time of initial measurement: (1) such designation can eliminate or significantly reduce accounting mismatch; (2) according to the company risk management or investment strategy stated in formal written documents, the management and performance evaluation for the financial liabilities portfolio or portfolio of financial assets and financial liabilities is conducted on the basis of fair value, which is reported to key management personnel within the Company on this basis; (3) the financial liabilities include embedded derivatives that need to be split separately. 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 91 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. 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. The Company, taking into account all reasonable and well founded information (including forward-looking information) estimates the expected credit losses of financial assets measured at amortized cost and financial assets (debt instruments) measured at fair value with changes included in other comprehensive income in a single or combined way. (1) Measurement of expected credit loss If the credit risk of the financial instrument has increased significantly since the initial recognition, the Company measures its loss provision according to the amount equivalent to the expected credit loss of the financial instrument in the whole duration; if the credit risk of the financial instrument has not increased significantly since the initial recognition, the Company measures its loss provision according to the amount equivalent to the expected credit loss of the financial instrument in the next twelve months. The increased or reversed amount of the loss provisions arising therefrom shall be included in the current profits and losses as impairment losses or gains. The specific assessment of credit risk by the Company is detailed in the Note "IX. Risks Associated with Financial Instruments". Generally, if it is overdue for more than 30 days, the Company considers that the credit risk of the financial instrument has increased significantly, unless there is conclusive evidence to prove that the credit risk of the financial instrument has not increased significantly 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: 92 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. First stage: credit risk has not increased significantly since initial recognition For the financial instrument at this stage, the enterprise shall measure the loss provision according to the expected credit loss in the next 12 months, and calculate the interest income as per its book balance (i.e. without deducting the impairment provision) and the actual interest rate (if the instrument is a financial asset, the same below). Second stage: the credit risk has increased significantly since the initial recognition, but the credit impairment has not occurred For the financial instrument at this stage, the enterprise shall measure the loss provision according to the expected credit loss of the instrument thought the whole duration, and calculate the interest income as per its book balance and the actual interest rate. Third stage: credit impairment occurs after initial recognition For the financial instrument at this stage, the enterprise shall measure the loss provision according to the expected credit loss of the instrument thought the whole duration, but the calculation of interest income is different from the financial assets at the first two stages. For the financial assets with credit impairment, the enterprise shall calculate the interest income according to its amortized cost (book balance minus accrued provision for impairment, i.e. book value) and the actual interest rate. For the financial assets with credit impairment at the time of purchase or origination, the enterprise shall only recognize the change of expected credit loss in the whole duration after initial recognition as loss provision, and calculate the interest income as per its amortized cost and the effective interest rate adjusted by credit. (2) For financial instruments with low credit risk on the balance sheet date, the Company directly assumes that the credit risk of such instruments has not increased significantly since the initial recognition, while not comparing them with the credit risk at the time of initial recognition. A financial instrument may be considered to have a lower credit risk if the enterprise recognizes that the financial instruments feature low default risk, the borrower is able to fulfill its obligations to pay the contractual cash flow in the short term, and that even if there are adverse changes in economic situation and operating environment over a longer period of time, it does not necessarily reduce the borrower's ability to fulfill its obligations to pay the contractual cash flow. (3) Receivables and lease receivables 93 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. 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 If the Company has transferred almost all risks and rewards in the ownership of financial assets to the transferee, the financial assets shall be derecognized, and if it retains almost all risks and rewards in the ownership of the financial assets, the financial assets shall not be derecognized. If the Company neither transfers nor retains almost all the risks and rewards in the ownership of the financial asset, the following conditions shall be referred to: if it gives up the control over the financial asset, it shall terminate the recognition of the financial asset and recognize the assets and liabilities generated; if it does not abandon the control over the financial asset, the relevant financial assets shall be recognized according to the extent to which it continues to be involved in the transferred financial asset, and the relevant liabilities shall be recognized accordingly. If the financial guarantee is provided to the transferred financial assets to continue to be involved, the assets generated from the continued involvement shall be recognized according to the lower of the book value of the financial assets and the amount of financial guarantee. Financial guarantee amount refers to the maximum amount that will be required to be repaid out of consideration received. 11. Notes receivable The Company divides notes receivable into two portfolios of bank acceptance bills and commercial acceptance bills by type of financial instrument. With respect to bank acceptance bills, the Company considers its overdue default risk to be 0 for it has low overdue credit loss which has not significantly increased since the initial recognition, because the acceptance bank pays the payee or holder a certain amount unconditionally when the bill is due. In respect of commercial acceptance bills, the Company believes that the probability of default is correlated with the 94 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. aging, and the transfer provision shall be accrued according to the accounting estimate policy of expected credit loss of above accounts receivable. 12. Accounts receivable The Company measures the loss provisions as per the amount of expected credit losses throughout the whole duration by the use of simplified model for expected credit loss for receivables specified in Accounting Standards for Business Enterprises No. 14 - Income, excluding significant financing components (including cases in which financing components in contracts not exceeding one year are not taken into account in accordance with the standards). The increased or reversed amount of loss provisions generated therefrom shall be included in the current profits and losses as impairment losses or gains. The Company has implemented Accounting Standard No. 22 - Recognition and Measurement of Financial Instruments (CK [2017] No. 7) since January 1, 2019. The Company believes that the probability of default is related to the aging, which is still a mark of whether the credit risk of the Company's accounts receivable increases significantly, after it has reviewed the appropriateness of the provision for bad debts receivable in previous years based on the Company's historical bad debt losses. Therefore, credit risk loss of the Company's accounts receivable is still estimated on the basis of aging according to the original loss ratio of previous years. The accounting policies for measuring overdue credit loss of accounts receivable adopted by the Company are as follows: 1. Receivables with significant individual amount and individual provision for bad debts Significant individual amount refers to the amount of which the ending balance of individual receivables is more than 1 million yuan. 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. 95 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. Except for the receivables for which impairment provision has been made separately, the Company determines the proportion for following bad debt provision based on the actual loss rate of the portfolio of the same or similar receivables in previous years with the aging of receivables as the credit risk feature and in combination with the current situation: 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 Note: when measuring the expected credit loss of receivables, the Group 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 single 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. 13. Receivables financing Financial assets that meet the following conditions at the same time are classified as financial assets measured at fair value through other comprehensive income: The business model for managing the financial assets by the Company is to collect contractual cash flows and to sell financial assets; The contract terms of the financial asset stipulate that the cash flow generated on a specific date is only the payment of the principal and the interest based on the outstanding principal amount. 96 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. If the Company transfers the receivables held by it in the form of discount or endorsement, which is frequent and involves a large amount, and its management business mode is essentially the collection and sale of the contractual cash flow, it is classified into financial assets whose changes are measured at fair value and included in other comprehensive income in accordance with the accounting standards of financial instruments. 14. Other receivables Recognition method and accounting treatment method for expected credit loss 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: Items Basis for determining the portfolios Risk-free portfolio This portfolio is a risk-free account receivable. Aging portfolio The credit risk of the portfolio is characterized by the aging of receivables. 15. Inventories 1. Classification of inventories Inventories refer to the finished products or commodities held by a company for sale, the unfinished products in the process of production and outsourced processing, and the materials and supplies consumed for production or rendering of labor service in daily activities of the Company. The Company's inventories mainly include raw materials (including auxiliary materials and wrappage), outside processing materials, unfinished products, self-made semi-finished products, goods on hand and low value consumables. 2. Pricing method of delivered inventories The delivered inventories are subject to the weighted-average system. 3. Determination basis for net realizable value of the inventory and counting and drawing method for inventory falling price reserves 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 97 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. 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. Net realizable value refers to the amount of the estimated sale price of the inventories minus the costs, sales expenses and relevant taxes estimated to be incurred up to completion in daily activities. For the provision of inventory revaluation reserve, it is made based on a single inventory item for various inventories and in a combined manner for the inventories which are related to the product line produced and sold in the same region, difficult to be measured separately from other items and for the same or similar end use or purpose. 4. Inventory system Perpetual inventory system is applied for the inventories. 5. Amortization method of low value consumables and packaging materials Both low value consumables and wrappage are amortized with one-off amortization method when they are received. 1.

Contractual assets None 17. Contractual costs None 18. Assets held for sale The Company classifies corporate components (or non-current assets) that meet the following conditions as the assets held for sale: (1) The corporate components can be sold immediately under current background in accordance with the practice of sales of such assets or disposal portfolio in similar transactions; (2) The sale is very likely to take place and expected to be completed within one year since a resolution has been made on a sale plan and a definite purchase commitment has been obtained(definite purchase commitment refers to a legally binding purchase agreement that is signed by a company with other parties and indicates the important clauses with respect to the transaction price, time and severe penalties for breach of contract to minimize the possibility of major adjustment or revocation of the agreement.). It has been approved by the relevant authority or regulators in accordance with relevant regulations. 99 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. The Company adjusted the estimated net residual value of the asset held for sale to the net amount (not more than the original book value of such asset held for sale) reflecting its fair value minus the sales expenses. If the original book value is higher than the adjusted estimated net residual value, the difference between the two was deemed as the asset impairment loss and included in the current profits and losses, and the provision for impairment of assets held for sale shall be made. For the amount of asset impairment loss recognized for the disposal portfolio held for sale, it is necessary to offset the book value of goodwill in the disposal portfolio and then offset the book value of the specified non-current assets in the disposal portfolio applicable for being measured in accordance with the Standard in proportion. If the net amount of the fair value of the non-current assets held for sale minus the sales expenses increases on the subsequent balance sheet date, the amount written-down previously shall be recovered and reversed within the amount of asset impairment loss recognized after such non-current assets are classified as the assets held for sale. The reversed amount shall be included in the current profits and losses. The asset impairment loss recognized before such non-current assets are classified as the assets held for sale shall not be reversed. If the net amount of the fair value of the disposal portfolio held for sale minus the sales expenses increases on the subsequent balance sheet date, the amount written-down previously shall be recovered and reversed within the amount of impairment loss recognized for the non-current assets applicable for being measured in accordance with the Standard after such disposal portfolio is classified as the assets held for sale. The reversed amount shall be included in the current profits and losses. It is not allowed to reverse the book value of the goodwill that has been written down and the impairment loss recognized for the non-current assets applicable for being measured in accordance with the Standard before such assets are classified as the assets held for sale. The book value of the subsequently reversed amount of the asset impairment loss recognized for the disposal portfolio held for sale shall be increased according to the proportion of the book value of non-current assets applicable for being measured in accordance with the Standard except for the goodwill in the disposal portfolio. If the Company loses control over its subsidiary for some reasons such as the sale of its investment into its subsidiary, it shall classify the entire investment into its subsidiary as the assets held for sale in the individual financial statement of the parent company and classify all assets and liabilities of the subsidiary as the assets held for sale in the consolidated financial statements provided that the investment into its subsidiary to be sold meets the conditions for classification of assets held for sale. 100 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. 19. Debt investment None 20. Other debt investment None 21. Long-term receivables None 22. Long-term equity investment 1. Determination of investment costs (1) If the investment cost is incurred in business combination 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 business combination 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 business combination under different control, the initial investment cost shall be determined as the fair value of the consideration paid for combination on the purchase date. 101 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. (3) Investment costs other than those incurred in business combination: 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 profit, and it is necessary to consider whether the long-term investment is impaired in accordance with the relevant policy of asset impairment. When the equity method is applied, if the initial investment cost of a long-term equity investment is greater than the share of fair value of identifiable net assets entitled from the investee at the time of investment, it shall be included in the initial investment cost of the long-term equity investment; otherwise, the difference shall be included in the current profits and losses and the cost of long-term equity investment shall be adjusted. When the equity method is applied, the profits and losses on investment shall be recognized and the book value of the long-term equity investment shall be adjusted according to share of the net profits and losses that shall be entitled or shared and have been realized by the investee after the long-term equity investment is obtained. When the share of the net profits and losses 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. The Company recognizes the net loss incurred by the investee to the extent that the book value of the long-term equity investment and other long-term equity substantially constituting the net 102 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. investment into the investee are written down to zero, unless the Company is liable for extra 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 profit 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 long-term equity investment shall be recognized as investment profit (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 103 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. 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.

If there is any sign showing that the investment property is impaired on the balance sheet date, the provision of impairment reserve shall be made accordingly based on the difference between the book value and the recoverable amount. The Company applied the cost model to subsequent measurement of investment property, and depreciated or amortized it in accordance with the policy as used for the buildings or land use rights. See Note V. (XXIII) "Long-term Assets Impairment" for details of the methods for impairment test and provision of impairment reserve applicable to investment property. If the property for private use or inventory is converted to an investment property or the investment property is converted to a property for private use, the book value before such conversion shall be deemed as the entry value after the conversion. If the purpose of an investment property is changed to private use, this investment property shall be converted into a fixed or intangible asset from the date of change. If the purpose of a property is changed to rent gains or capital appreciation from private use, the fixed asset or intangible asset shall be converted into an investment property from the date of change. If the purpose of a property is changed to rent gains or capital appreciation from private use, the fixed asset or intangible asset shall be converted into an investment property from the date of change. If any asset is converted into an investment property measured with the cost model, the book value before the conversion shall be deemed as the entry value after the conversion. If any asset is converted into an investment 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 Company has fulfilled performance obligation in the Contract, that is, recognizing revenue when the customer obtains the control right of relevant commodities. Obtaining of the control right of relevant commodities means to be able to dominate the use of the commodities and obtain almost all economic benefits arising therefrom. 2. The Company shall judge the nature of relevant performance obligations as "performance obligations fulfilled in a certain period" or "performance obligations fulfilled at a certain time point" based on relevant provisions of revenue standards, and shall confirm revenue according to the following principles respectively. (1) In case the Company meets one of the following conditions, it shall fulfill the performance obligations within a certain period of time: ① Customers obtain and consume economic benefits arising from performance of the Company during the Company's performance of the Contract. ② Customers can control the assets under construction during the Company's performance of the Contract. ③ Assets of the Company during the performance of the Contract are irreplaceable, and the Company shall be entitled to collect money for the performance part completed so far in the whole contract period. For performance obligations fulfilled within a certain period of time, the Company shall recognize revenue according to the performance progress within that period, except that the performance progress cannot be reasonably determined. The Company shall consider the nature of commodities, and shall determine the proper performance progress by adopting the output method or the input method. (2) For performance obligations fulfilled at a certain time point rather than in a certain period, the Company shall recognize revenue at the time when customers obtain the control right of relevant commodities. When judging whether customers have obtained the control right of relevant commodities, the Company consider the following signs: ① The Company shall be entitled to immediately collect revenues from commodities, which means that customers have the obligation to pay for commodities immediately. ② The Company has transferred the legal ownership of commodities to customers, which means that customers have obtained the legal ownership of commodities. ③ The Company has transferred commodities in kind to customers, which means that customers have possessed commodities in kind. ④ The Company has transferred main risks and rewards related to the ownership of commodities to customers, which means that customers have obtained main risks and rewards related to the ownership of commodities. 115 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. ⑤ Customers have accepted the commodities. ⑥ Other indications that customers have obtained the control right of commodities. 3. The specific method of revenue recognition of the group 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. 4.

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. 116 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. 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.

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 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.

The enterprise shall continuously evaluate whether the hedge relationship conforms to the hedge effectiveness requirements when the hedge begins and during the sequent periods, especially for the analysis of the forming reasons why it is expected to affect the hedge relationship due to the invalid part of the hedge during the residual periods of the hedge. The enterprise shall at least evaluate the hedge relationship on the day of balance sheet and when the major changes will happen for relevant situations affecting the hedge effectiveness requirements.

Risks Associated with Financial Instruments The main financial instruments of the Company include equity investment, debt investment, borrowings, accounts receivable, accounts payable, convertible bonds, etc. For details of each financial instrument, please refer to the relevant items in this report. The risks associated with these financial instruments and the risk management policies adopted by the Company to mitigate these risks are described below. The Management of the Company manages and monitors these risk exposures to ensure that these risks are controlled within the limited scope. 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 group's financial instruments include the credit risk, liquidity risk and market risk. (I) Risk management objective and policy The Company's risk management objective is to strike an appropriate balance between risks and returns, reduce the negative impact of risks on the Company's business performance to the lowest level, and maximize the interests of shareholders and other equity investors. Based on this risk management objective, the basic risk management strategy of the Company is to determine and analyze various risks faced by it, establish an appropriate risk bearing bottom line and carry out risk management, and conduct timely and reliable supervision of various risks to control risks within the limited scope. 1. Market risk 187 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. (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 DONGNAI (VIETNAM) Co., Ltd., the grandson companies, use Vietnamese dong, and Topband Germany GmbH, the grandson company, uses Euros; TOPBAND JAPAN Co., Ltd., the grandson company, uses Japanese yen, Q.B.PTE. LTD, the grandson company, uses Singapore dollars, and TOPBAND MEXICO, S.DE R.L.DE C.V., the grandson company, uses Mexican pesos; TOPBAND SMART EUROPE COMPANY LIMITED S.R.L., the grandson company, uses Romanian Leu, Tunnu Innovation HK Limited, the grandson company, uses Hong Kong dollars, and TUNNU INNOVATION, INC, the grandson company, uses US dollars; other major business activities of Topband are settled in RMB. As of June 30, 2022, the assets and liabilities of the Company are all in RMB, except for those described in this report "Foreign currency monetary items" that the assets and liabilities are in US dollars, Hong Kong dollars, Euros, Vietnamese dong and Indian rupee. 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 June 30, 2022, the maximum credit risk exposure causing the Company's financial losses is mainly incurred from the other party's failure to fulfill obligations, which leads the Company to financial asset losses, and financial guarantee undertaken by the Company, including confirmed carrying amounts of financial assets in consolidated balance sheets; the carrying value only reflects risk exposure of financial instruments measured at fair value rather than the maximum risk exposure, that varies with the fair value in the future. In order to reduce credit risks, the Company has set up special positions responsible for determining credit limits, conducting credit approval, and implementing other monitoring procedures to ensure that necessary measures 188 Full Text of Semi-annual Report 2022 of Shenzhen Topband Co., Ltd. are taken to recover overdue claims. In addition, the Company reviews the recovery of each individual receivables on each balance sheet date to ensure that adequate provision is made for uncollectible amounts. As a result, the Management of the Company believes that the credit risk assumed by the Company has been significantly reduced. The Company's working capital is deposited in a bank with a high credit rating, so the credit risk of working capital is low. The Company has adopted necessary policies to ensure that all sales customers have good credit records. The Company has no other major credit concentration risk. 3. Flow risk In managing liquidity risks, the Company maintains and monitors cash and cash equivalents deemed sufficient by the Management 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. The Management of the Company monitors the use of bank loans and ensures compliance with loan agreements. XI. Disclosure of Fair Value 1.
