Faced with difficulties and challenges, we chose to share risks and benefits, conduct long-term cooperation with our customers and accomplish customers so as to achieve mutual prosperity and development and boost the development of an intelligent and low-carbon world. Thanks to the efforts of all Topband staff, operating revenues of the Company achieved a compound growth rate of over 30% in the past five years. The Company achieved operating revenues of 7.767 billion yuan during the reporting period, a year-on-year increase of 39.69%, net profits of 565 million yuan attributable to shareholders of listed companies, a year-on-year increase of 6.16%, and net profits of 432 million yuan attributable to shareholders of listed companies after deduction of non-recurring gains and losses, a year-on-year increase of 13.28%. Annual operating performance and core operating indicators in 2021: (I) Revenues more than expected and achievement of annual sales targets 1. Expansion of intelligent scenarios, opening up the space for industry growth With the accelerated arrival of the intelligent society, the industry development has entered the fast lane and will be a long-term process, the application scenarios of intelligent controllers continue to expand, and the downstream demand will still maintain a high degree of prosperity. External factors such as the epidemic and turbulence in the supply market may affect the rhythm of industry demands in the short term, but will not affect the sustained growth of the industry brought about by intelligence, low carbon and multi-regional development. For mature business, we went to the front end to gain insight into market opportunities, deeply understand customer needs, seize new opportunities constantly and strive for more orders to ensure the scale advantage of the Company. For growing business, we improved our ability continuously and gave full play to our existing advantages to incubate and market innovative products constantly and achieve commercial success. At the same time, we continued to expand new tracks and open up new growth points, and finally achieved long-term strategic goals. Looking forward to the future, we are confident to grasp new opportunities in the market, continue to 20 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. deepen the intelligent control industry, lead the industry forward, and become a global leading and respected intelligent control solution provider. 2. Achievement of annual sales targets beyond the expected and consolidation of the leading position of the Company The epidemic in China and abroad had repeated outbreaks in 2021. Facing the complicated and volatile business environment such as raw material price increase and shortage under the influence of the epidemic and inflation, the management of the Company responded positively, seized the opportunity of intelligent upgrading and demand concentration improvement according to the strategy of "supply guarantee" formulated at the beginning of the year, and implemented the five core strategies unswervingly to seize market share rapidly. In 2021, the five major sectors of the Company achieved good growth year on year, and the customer structure became healthier. The number of head customers exceeded 100, revenues from which accounted for more than 80% of the Company's total operating revenues. We realized the growth of both the number and volume of head customers, laying a solid foundation for the subsequent sustained and steady growth. 3. Shoulder-to-shoulder and distinctive development of all business units (1) Tool unit: becoming the first business unit of the Company. In 2021, the sales revenue was 2.994 billion yuan, a year-on-year increase of 43.36%.The downstream market of the tool unit is concentrated. With obvious advantages in the unit, the Company has entered the supply system of several head customers. Its market share increased steadily. Product categories expanded horizontally. Except for electric tools, garden tools, utility lights and floor care and cleaning products all achieved rapid growth during the reporting period. The main driving force for the growth of the unit is the continuous expansion of application scenarios, the opening of incremental market, the upgrading of technology in stock market, and the realization of lithium battery and cordless application. The sustained growth of the industry will not be changed by short-term factors such as the epidemic. (2) Home appliance unit: maintaining a strong growth trend with the growth rate higher than the average of the industry as the basic business of the Company. In 2021, the sales revenue was 2.959 billion yuan, a year-on-year increase of 37.36%.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, 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 21 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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: In 2021, the sales revenue reached 1.241 billion yuan, up 38.86% year-on-year. Focusing on energy storage, green commuting and other fields, the unit has become the third growth curve of the Company. Relying on years of technology accumulation and stable quality assurance, we can open the market quickly with the advantages of customized solutions and continue the trend of high growth in the future. Energy storage: In 2021, the sales revenue was 881 million yuan, accounting for about 70% of the new energy unit, a year-on-year growth of 37.74%.The main application fields of energy storage were household energy storage, portable energy storage, standby power for communication and industrial and commercial energy storage. The operating revenue of household energy storage and portable energy storage doubled during the reporting period. It is expected to continue the high growth trend in 2022.In terms of household energy storage, complete lithium battery products were provided for overseas household energy storage and electrical power supply for RVs and yachts. In portable energy storage, inverter products were mainly provided for head customers in China. The proportion of standby power for communication decreased year on year due to the price increase of upstream materials and the limitation of production capacity. Industrial and commercial energy storage accounted for a low proportion. It is expected to build a new growth point in the future. Green travel. In 2021, the sales revenue reached 360 million yuan, accounting for about 30% of the new energy unit, a year-on-year growth of 41.66%.The main application fields were new energy vehicles and light power. In the field of new energy vehicles, charging pile controllers, electronic water pumps and DC brushless motors were mainly provided. In 2021, the sales revenue was about 100 million yuan, a year-on-year growth of 157.30%.With the popularization of new energy vehicles, it is expected to continue the trend of high growth. In the field of light power, BMS or complete products were mainly provided for swap cabinets, electric motorcycles and tricycles and mobile robots. The growth of the unit was lower than expected due to the influence of upstream materials. (4) Industrial unit: In 2021, the sales revenue was 295 million yuan, a year-on-year increase of 14.41%. The Company mainly provides controllers, drivers and motors for downstream automation equipment customers, which are widely used in 3C electronics, robotics, medical equipment, semiconductor equipment, textile machinery, packaging machinery, etc. We are committed to helping automation equipment manufacturers improve 22 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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: In the field of intelligent solutions, comprehensive solutions of "innovative products + AIoT platform + customized service" are provided for the subdivided scenes such as "food, clothing, housing and transportation" and "industry, restaurants, hotels and parks" based on the AloT (Artificial Internet of Things) technology platform and intelligent product innovation capability of the Company. In 2021, the sales revenue was 221 million yuan, a year-on-year increase of 60.40%, among which the revenue of networked products doubled. (II) Supply side faced with severe challenges The supply market was extremely turbulent in 2021. The extensive shortage of raw materials and the continuous sharp increase of prices aggravated the original complex supply and manufacturing pattern. Due to the variety of upstream raw materials of the Company, the uncertainty of supply brought great challenges to its procurement, production and delivery. In comparison with the shortage of materials in 2018, the management of the Company anticipated the severe situation in advance and formulated important strategic measures of "supply guarantee" in time at the beginning of the year. It guaranteed the timely delivery of customer orders to the greatest extent and reduced the impact of shortage and price increase on business delivery greatly by communication with customers in advance about demand plans, stocking in advance, domestic substitutions and stock allocation at high prices. However, the Company failed to achieve the goals of material cost reduction and manufacturing efficiency improvement set at the beginning of the year due to the significant price rise of some raw materials and the serious shortage of supply. Some orders experienced stock allocation at high prices in the second half of 2021, and the costs were not greatly transmitted to downstream and new products, which had a certain impact on the Company's operating profits in the short term. With the gradual decline of raw material prices in the future, its profitability is expected to return to the normal level and the growth rate of profits will also recover gradually. (3) Adhering to R&D investment and tapping the blue ocean market driven by innovation The Company adheres to the concept of creating value for customers and society, always takes "technological innovation" as its engine, continuously deepens the technological leading ability and constructs a new driving force for enterprise development. In 2021, the Company continued to promote and deepen the technology accumulation and application of "electronic control, motor, battery, power supply and Internet of 23 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. Things platform" in five major industries, and accelerated the integration and application of new technologies such as AI, IOT and 5G and the implementation of more scenarios. The total R&D investment of the Company was 560 million yuan during the reporting period, up 41.02% year-on-year, accounting for 7.21% of operating revenues. There were nearly 1,600 R&D and technical service personnel. The Company created an innovative cultural atmosphere internally and strengthened the protection of independent and controllable products and independent intellectual property rights externally. The Company and its subsidiaries applied for 2,346 patents, including 868 patents for invention, 1,209 utility models, 193 design patents, 23 foreign patents and 53 PCTs, 85 software copyrights and 276 trademarks accumulatively at the end of the reporting period. The R&D investment of the Company accounted for about 7% of its operating revenues in the past ten years. With a high proportion of continuous R&D investment, a lot of innovative products emerged, such as inverters, thermostats, cooking machines, lawn mowers and floor washers. The proportion of independent and controllable business increased rapidly in 2021, contributing a steady stream of power to the future sustainable development. The Company also started a business model of long-term development driven by innovation. (IV) Multi-regional common development and accelerated process of internationalization We are an international company with customers all over the world. Focus on the strategy of “customer intimacy”, we serve customers closely and improve the service responsiveness and the service quality further. We set up more than ten regional operation centers, manufacturing centers, R&D centers and representative offices in many places around the world based on the needs of business development. In 2021, Vietnam Phase II went into production quickly in spite of many difficulties, and overseas operation centers in Germany and North America and manufacturing centers in Romania and Mexico were newly established to accelerate the international layout and realize agile delivery. The current main production capacity layout of the Company is as follows: The Pearl River Delta: Include the Shenzhen headquarters and Huizhou. Huizhou Subsidiary is the main source of production capacity, with stable production capacity and quality. At the same time, some leased factories have been added to meet the fast-growing demand. Yangtze River Delta region: Ningbo Operation Base was completed at the end of 2021 and put into service in 2022 and has now entered the capacity climbing period. It will gradually release the capacity. Nantong Lithium Battery Industrial Park is going through property rights delivery according to the agreement and is expected to be put into service in the second half of 2022. 24 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. Southeast Asia - Vietnam: Though Vietnam Binh Duong Company (Phase I) was affected by the epidemic in 2021, it overcame many difficulties, including personnel and materials, to help customers realize the agility and safety of the supply chain and contributed an output value of 552 million yuan. Vietnam Dong Nai Company (Phase II) was put into production successfully during the reporting period, and will contribute new capacity in 2022. Southeast Asia - India: India experienced severe epidemic in 2021. The Company achieved the production capacity target set at the beginning of the year during the reporting period by telecommuting means such as video and internet. During the reporting period, Indian Subsidiary also obtained the BIS product certification of inverter air conditioner controllers in India issued by the Bureau of Indian Standards (BIS for short), and became one of the first enterprises in the world to pass the certification. (V) Cash flow from operating activities In 2021, the net cash flow generated by the Company's operating activities was -225 million yuan, down by 134.66% year-on-year, mainly due to the epidemic in combination with the turbulent supply of raw materials and the stocking in advance, stock allocation at high prices and advance payment for the purpose of ensuring the timely delivery of customer products. It is expected that the operating cash flow will improve after stabilization of the supply. (VI) Capital operation: non-public offering + acquisition + equity incentive 1. Non-public offering of shares, raising funds of 1.05 billion yuan successfully. During the reporting period, the Company privately issued 92,105,263 A-share stocks to 14 subscribers, raising 1.05 billion yuan in total, the privately issued shares were listed on Shenzhen Stock Exchange on June 3, 2021, and the raised funds are intended to be used for the construction of Huizhou No. 2 Industrial Park and supplement the Company's working capital; To speed up the project, the implementation site and mode of some raised funds were changed upon review and approval of the shareholders’ meeting of the Company in January 2022. 2.

During the reporting period, the Company launched a restricted stock incentive plan, granting a total of 33.54432 million restricted stocks to 1,224 employees, and practiced its philosophy of "value co-creation and sharing" with the continuous high growth of performance as the unlocking condition, allowing the core backbone of the Company to truly become its owner and stimulating the internal drive of employees to realize the common growth of individuals and organizations. (VII) Other factors influencing profits 1. Increase of fair value gains, increasing the Company's non-recurring operating profit. During the reporting period, the book value of the Company's equity investment in ORVIBO increased somewhat than at the end of 2020, and the change in the fair value of the investment increased the Company's non-recurring operating profit by about 93.347 million yuan in 2021. 2. Provision for credit impairment, reducing the Company's current recurring operating profit. With the increasing complexity of the global economic situation, the uncertainty faced by business entities has increased. Individual customers of the Company made overdue payment and had business risks. The Company fully accrued 69.2331 million yuan of provision for credit impairment reserve according to the requirements of accounting standards. 2.

The advantages of China's industrial clusters and engineer dividends have accelerated the trend of transfer. With the influence of international trade conflicts, the industry has gradually shown the trend of development mainly in China and towards Vietnam, India, Indonesia and other regions. The Company will actively expand new opportunities in many regions. 4. Short chain The industrial chain is shortened in value and the products directly address the needs of users. The traditional value chain is transformed into a new value chain. We will explore new opportunities with more partners and users boldly. Description of 2030 vision of the Company "In 2030, the Company will provide intelligent solutions through insight into users, scenes and industry pain points, making the world smarter and lower-carbon and greatly increasing the proportion of solution revenues.” The future will be an intelligent society, and intelligentization will be a long-term, lasting and far-reaching change having a wide influence, and will deeply affect modern life, and change product forms at the same time.

Focus on strategy and sustained and effective growth A vision blueprint for the next ten years was formulated in 2021 based on the medium-term development goal of the Company in 2025, in which the long-term development goal in 2030 was made clear. The Company will continue to focus on scale growth, deepen the implementation of the four strategic policies - "customer intimacy, innovation drive, fine operation and organizational evolution", build a pyramid profit model, enhance its leading position in global intelligent control solution providers, and achieve sustained and effective growth. The Company will provide one-stop intelligent control solutions and services for the world’s leading brand customers with the advantage of the “four electrics and one network” technology, and focusing on five main businesses of the “home appliances + tools + new energy + industry + intelligent solutions”, and make good use of the capital market platform to achieve high growth in operating income scale through a combination of endogenous and extended methods. 2. Innovation drive and continuous enhancement of the competitiveness of technologies and products The Company will adhere to innovation drive, maintain R&D investment continuously, strengthen basic and cutting-edge technology research, and set up technical control points; strengthen the construction of product lines and build more high-quality product platforms; promote the protection of intellectual assets such as patents and trade secrets, and build technical barriers; cultivate the engine of innovation and growth, and strengthen the cultivation of innovative talents. It will meanwhile seize the development opportunities such as "intelligence" and "low-carbon development", actively explore innovative services such as the Internet of Things and green commuting, consolidate and expand the core technical capabilities of "electronic control, motor, battery, power supply and Internet of Things platform", enhance the market and product development capabilities, and explore more high-value markets. 3. Fine operation and improvement of quality and efficiency The Company will deepen the implementation of the fine operation strategy, optimize business processes such as strategy, market, R&D, sales, procurement and after-sales service continuously, and improve the end-to-end efficiency. 4.

Acceleration of global layout and construction of global delivery capability The Company will continue to strengthen the customer intimacy strategy. To meet customer demands for fast delivery and delivery with proximity, the Company has established operation centers, manufacturing centers, R&D centers and representative offices in many places around the world based on business needs. During the reporting period, it completed the construction of Ningbo Industrial Park, realized the rapid commissioning of the plant in Binh Duong, Vietnam, and accelerated the construction of plants in Mexico and Romania. At the same time, the Company has strengthened the integration of supply chain based on global layout advantages and enhanced the local purchasing ability. (III) Business plan for 2022 1. Realization of scale growth: The Company will continue to implement the head customer strategy, give full play to platform advantages and increase the share of overseas plants to achieve scale growth of various industries based on the core technology of "electronic control, motor, battery, power supply and Internet of Things platform", and meanwhile increase the proportion of high-value products and independent and controllable businesses; 2.

(IV) Fund demand and utilization plan Since the Company is in the stage of rapid development, it has a huge fund demand in equipment upgrading and capacity expansion. The Company has a good credit standing, so it is able to get strong support from the bank in a timely manner. In 2022, taking into account its own development situation and development strategy, the Company has raised the funds required for its development through reasonable use of various ways. (V) Risks faced by the Company and countermeasures 1. External risks such as the macro environment 54 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. The global epidemic will still make impact on economic activities before control, and trade frictions and geopolitical tensions will also produce adverse influences on business confidence and investment. The Company may continue to face an uncertain external environment, so we will further strengthen risk identification and control for various businesses and regions and adjust strategies timely to minimize external influences. 2. Risk of technology upgrading The intelligent controller industry technology, as the main business of the Company is developing rapidly with fast product upgrading and short life cycle. Although the Company continues to invest in research and development and owns a number of invention and utility patents, there is still a risk that the technology will not be updated in time to meet market demand, or lag behind competitors in launching new products, resulting in a decline in the market share and profitability of the Company. 3. Exchange rate risk The Company's revenue from export sales accounts for more than half of total revenue. In order to cope with the risk of exchange rate fluctuation, the Company will reduce and hedge foreign exchange risks by conducting RMB hedging business, international procurement and re-pricing of new product. (4) Other risks There are many uncertainties in the current macro environment at home and abroad, and there are some factors that are unfavorable to the operation of the Company. For example, the Sino-US trade war, the recurrence of COVID-19, the shortage of raw materials or the price rise, the lack of manpower and customer credit risk will increase the uncertainty of the Company's operation.

A misstatement may be caused by fraud or errors. Misstatements are generally deemed to be material if it is reasonably expected that they may, individually or collectively, influence the economic decisions made by the users of the financial statements according to the financial statements. We have exercised our professional judgment and maintained our professional skepticism in carrying out the audit according to audit standards. At the same, we have carried out the following work: (1) We have identified and assessed the risks of material misstatements caused by fraud or errors in the financial statements; have designed and implemented audit procedures to cope with such risks; and have obtained sufficient and appropriate audit evidence as a basis for the expression of the audit opinion. Because fraud may involve collusion, falsification, intentional omission, misrepresentation or precedence over internal control, the risk of failure to detect material misstatements caused by fraud is higher than the risk of failure to detect material misstatements caused by errors. (2) We have understood the internal control related to the audit to design appropriate audit procedures, but our purpose is not to express our opinion on the effectiveness of internal control. (3) We have evaluated the appropriateness of the accounting polices chosen by the Management and the reasonableness of the accounting estimates and relevant disclosure made by it. (4) We have reached a conclusion on the appropriateness of the use of the going concern assumption. At the same time, according to the received audit evidence, we have reached a conclusion on the existence or non-existence of material uncertainty about any matter or situation that may cast considerable doubt on Topband Company's ability to continue as a going concern. If our conclusion is that material uncertainty exists, the audit standards require us to bring relevant disclosure in the financial statements to the attention of the users of the statements in the audit report; if such disclosure is inadequate, we shall express a non-unqualified opinion. Our conclusion is based on the information that was available as of the date of the audit report. However, future matters or situations may cause Topband Company to lose the ability to continue as a going concern. (5) We have evaluated the overall presentation, structure and content of the financial statements and have evaluated whether the financial statements fairly present relevant transactions and matters. (6) We have obtained sufficient and appropriate audit evidence for the financial information on the entity or business activities of Topband Company to express our audit opinion on the financial statements. We are 154 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. responsible for guiding, supervising and implementing the group’s audit and bear full responsibility for the audit opinion. We have communicated with the Governance Body about the planned audit scope, timing and significant audit discovery, including internal control defects identified by us in the audit and deserving attention. We have also provided the Governance Body with a statement that we have complied with the professional ethics requirements relating to our independence and have communicated with the Governance Body about all relationships and other matters that may reasonably be believed to affect our independence, as well as relevant precautions. From the issues we have communicated with the Governance Body, we have determined which issues are the most important to the audit of the financial statements for the current period and thus constitute key audit matters. We describe these matters in our audit report, unless laws and regulations prohibit public disclosure of such matters or, in rare circumstances, we determine that we shall not communicate a certain matter in our audit report if it is reasonably expected that the negative consequences of communicating such matter in our audit report will exceed the benefits derived in the public interest.

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

The difference in translation of foreign currency financial statements generated from the above conversion is recognized as other comprehensive income. 10. Financial instruments 1. Recognition and de-recognition of financial instruments 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 198 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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. (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 199 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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 instrument 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. 200 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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 Financial liabilities measured at fair value through current profits and losses include trading financial liabilities (including derivatives belonging to financial liabilities) and financial liabilities designated at initial recognition as 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 201 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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 “9. 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 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). 202 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. Second stage: the credit risk has increased significantly since the initial recognition, but the credit impairment has not occurred For the financial instrument at this stage, the enterprise shall measure the loss provision according to the expected credit loss of the instrument thought the whole duration, and calculate the interest income as per its book balance and the actual interest rate. Third stage: credit impairment occurs after initial recognition For the financial instrument at this stage, the enterprise should measure the loss provision according to the expected credit loss of the instrument thought the whole duration, but the calculation of interest income is different from the financial assets at the first two stages. For the financial assets with credit impairment, the enterprise shall calculate the interest income according to its amortized cost (book balance minus accrued provision for impairment, i.e. book value) and the actual interest rate. For the financial assets with credit impairment at the time of purchase or origination, the enterprise shall only recognize the change of expected credit loss in the whole duration after initial recognition as loss provision, and calculate the interest income as per its amortized cost and the effective interest rate adjusted by credit. (2) For financial instruments with low credit risk on the balance sheet date, the Company directly assumes that the credit risk of such instruments has not increased significantly since the initial recognition, while not comparing them with the credit risk at the time of initial recognition. A financial instrument may be considered to have a lower credit risk if the enterprise recognizes that the financial instruments feature low default risk, the borrower is able to fulfill its obligations to pay the contractual cash flow in the short term, and that even if there are adverse changes in economic situation and operating environment over a longer period of time, it does not necessarily reduce the borrower’s ability to fulfill its obligations to pay the contractual cash flow. (3) Receivables and lease receivables The Company measures the loss provisions as per the amount of expected credit losses throughout the whole duration by the use of simplified model for expected credit loss for receivables specified in Accounting Standards for Business Enterprises No.14 - Income, excluding significant financing components (including cases in which financing components in contracts not exceeding one year are not taken into account in accordance with the standards). The Company makes accounting policy choices to adopt a simplified model for expected credit loss, i.e., 203 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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, it shall terminate the recognition of the financial assets, and if it retains almost all risks and rewards in the ownership of the financial assets, it shall not terminate the recognition of the financial assets. If the Company neither transfers nor retains almost all the risks and rewards in the ownership of the financial asset, the following conditions shall be referred to: if it gives up the control over the financial asset, it shall terminate the recognition of the financial asset and recognize the assets and liabilities generated; if it does not abandon the control over the financial asset, the relevant financial assets shall be recognized according to the extent to which it continues to be involved in the transferred financial asset, and the relevant liabilities shall be recognized accordingly. If the financial guarantee is provided to the transferred financial assets to continue to be involved, the assets generated from the continued involvement shall be recognized according to the lower of the book value of the financial assets and the amount of financial guarantee. Financial guarantee amount refers to the maximum amount that will be required to be repaid out of consideration received. 11. Notes receivable The Company divides notes receivable into two portfolios of bank acceptance bills and commercial acceptance bills by type of financial instrument. With respect to bank acceptance bills, the Company considers its overdue default risk to be 0 for it has low overdue credit loss which has not significantly increased since the initial recognition, because the acceptance bank pays the payee or holder a certain amount unconditionally when the bill is due. In respect of commercial acceptance bills, the Company believes that the probability of default is correlated with the aging, and the 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 204 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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. 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 205 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. combination with the current situation: Aging Estimated loss of accounts Estimated loss of other receivable (note) receivables Less than 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% Over 5 years 100.00% 100.00% Among which: those that have been determined to be Write off Write off irrecoverable 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 individual provision for bad debts Reasons for individual provision for bad debts: the Company conducts a separate impairment test for the receivables with the following characteristics, although its amount is not significant. If there is objective evidence that the receivables are impaired, the impairment loss shall be recognized with provision for bad debts according to the difference between the present value of future cash flow and the book value; receivables that are in dispute with the other party or involved in litigation or arbitration; receivables that have obvious indications that the debtor is likely to be unable to perform the repayment obligation, etc. Method for bad debt provision: the impairment test shall be conducted separately. If there is objective evidence that it has been impaired, the impairment loss shall be recognized with provision for bad debts according to the difference between the present value of future cash flow and its book value. 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. 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 206 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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 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. Valuation method of delivered inventories The delivered inventories are subject to the weighted-average system. 3. The basis for determination of net realizable value of inventories and the method for calculation of inventory revaluation 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 207 Full text of Annual Report 2021 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 wrappage Both low value consumables and wrappage are amortized with one-off amortization method when they are received. 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. Valuation method of delivered inventories The delivered inventories are subject to the weighted-average system. 3. The basis for determination of net realizable value of inventories and the method for calculation of inventory revaluation 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 208 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. realizable value. The net realizable value of the inventories ready for sale is determined at the estimated sale price of such inventories minus the estimated sales expenses and relevant taxes during normal production and operation, and that of the inventories to be processed is determined at the estimated sale price of the finished products minus the costs, sales expenses and relevant taxes estimated to be incurred up to completion during normal production and operation. On the balance sheet date, the net realizable values are determined separately and compared with the corresponding costs to determine the amount of withdrawal or reversal of inventory revaluation reserve if a part of inventory is subject to the contractual price agreement and the rest is not. 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. 16. Contractual assets None None 17. Contract 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. 209 Full text of Annual Report 2021 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. 210 Full text of Annual Report 2021 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 cost (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. (3) Investment costs other than those incurred in business combination: The initial investment cost shall be 211 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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 profit and loss 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 profit and loss on investment shall be recognized and the book value of the long-term equity investment shall be adjusted according to share of the net profit and loss that should 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. 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 investment into the investee are written down to zero, unless the Company is liable for extra losses. The 212 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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 profit and loss 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 investment (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 213 Full text of Annual Report 2021 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. 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.

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 224 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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. 225 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. ⑤ Customers have accepted the commodities. ⑥ Other indications that customers have obtained the control right of commodities. 3.

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. When evaluating whether the accumulative recognized revenue is unlikely to be significantly reversed, the 226 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. enterprise shall further consider the possibility and proportion of revenue reversal.

(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.

Risks Associated with Financial Instruments The main financial instruments of the Company include equity investment, debt investment, borrowings, accounts receivable, accounts payable, convertible bonds, etc. For details of each financial instrument, please refer to the relevant items in Note VI. The risks associated with these financial instruments and the risk management policies adopted by the Company to mitigate these risks are described below. The Management of the Company manages and monitors these risk exposures to ensure that these risks are controlled within the limited scope. The Company uses sensitivity analysis technology to analyze the possible impact of reasonable and possible changes in risk variables 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 (1) Foreign exchange risk 314 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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 rupees, 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 TOBAND MEXICO, S.DE R.L.DE C.V., the grandson company, uses Mexican pesos; TOBAND SMART EUROPE COMPANY LIMITED S.R.L., the grandson company, uses Romanian Lei, Tunnu Innovation HK Limited, the grandson company, uses Hong Kong dollars, and TUNNU INNOVATION, INC., the grandson company, uses US dollars; other major business activities of Topband are settled in RMB.As of December 31, 2021, the assets and liabilities of the company are all in RMB, except for those described in VI (56) “Foreign currency monetary items” that the assets and liabilities are in U.S. dollars, Hong Kong dollars, euro, Vietnamese dong and Indian rupees. 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 does not take any measures to avoid foreign exchange risks. (2) Other price risks Investments held by the Company and classified as tradable financial assets are measured at fair value on the balance sheet date. Therefore, the Company is exposed to the risk of changes in the securities market. 2. Credit risk On December 31, 2021, the maximum credit risk exposure causing the company's financial losses is mainly incurred from the other party's failure to fulfill obligations, which leads the company to financial asset losses, and financial guarantee undertaken by the company, including confirmed carrying amounts of financial assets in consolidated balance sheets; the carrying value only reflects risk exposure of financial instruments measured at fair value rather than the maximum risk exposure, that varies with the fair value in the future. In order to reduce credit risks, the Company has set up special positions responsible for determining credit limits, conducting credit approval, and implementing other monitoring procedures to ensure that necessary measures are taken to recover overdue claims. In addition, the Company reviews the recovery of each individual 315 Full text of Annual Report 2021 of Shenzhen Topband Co., Ltd. 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. XI. Disclosure of Fair Value 1.
