We will give full play to our advantages, make active deployment in the new energy and other emerging industries and strive to develop new customers, in order to mitigate the adverse effect of the relative concentration of customers on us. 2. Risks brought by rapid technology upgrading of the industry Our business covers PCB, photoelectric display, precision manufacturing and other technology-intensive industries, and our products are widely applied in consumer electronics, new energy vehicles, communication equipment, industrial equipment, and other fields, all of which are characterized by rapid technology upgrading. If our R&D and manufacturing capabilities fail to keep pace with the rapid technology upgrading of downstream products, our products and technologies may become obsolete. We will follow up on the new technologies and new processes of the industry from the strategic perspective and strive to keep our technologies and processes at the advanced level through continuous and effective R&D funding. 3. Risk of changes in the global trade environment Our major customers include some well-known international companies, and our export sales have grown steadily for years. Though China has established good economic and trade cooperation relationships with major countries in the world, the increasingly fierce regional frictions in recent years may cause uncertainties in the applicable trade policies, which could affect our international trade. We will follow up on the development of international trade frictions, strengthen communication with our customers, and continue to foster our competencies and customer adhesion. 4. Risk of market exploitation We are a strong R&D and manufacturing enterprise in the fields of PCB, photoelectric display and precision manufacturing. Due to our stable product quality and efficient customer services, we have remarkable competencies, and are able to provide the downstream enterprises with “one-stop” products and services, and satisfy their demands for systemic manufacturing solutions. However, our downstream industries are characterized by rapid upgrading and rapid changes in the preferences of consumers, among others. If our 26 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 major customers are at a disadvantage in the market, or we are unable to satisfy the demands of customers or fail to acquire new customers, the sales and margin rate of our products may decrease. We will continue to increase R&D funding, optimize our product mix and process structure, enhance our competencies, and actively cope with market competition. 5. Environmental risk In our production, the electroplating, etching and other processes produce wastewater, waste gases and solid wastes, and therefore are subject to strict requirements for environmental protection. We cannot exclude the possibility that environmental incidents may happen during our production due to negligence in management, force majeure or otherwise. If we meet with any environmental incident, that cause pollution to the environment or violates the applicable environmental protection laws and regulations, our reputation and operations could be adversely affected. Along with the vigorous development of a green and low-carbon circular economic development system and improvement of people’s living standard in China, and increasingly enhanced awareness of environmental protection of people, the country attaches increasingly great importance to environmental protection. If the country puts forward stricter environmental protection requirements, we may need to increase the funding for environmental protection, which would increase our environmental protection costs and in turn affect our results. We have set the building of an environment-friendly enterprise as a key goal of our sustainable development strategy, attached great importance to and increased the funding for environmental protection in our production and operation, actively responded to the requirements of the latest environmental protection laws and regulations, enhanced environmental protection training and employees’ awareness of environmental protection, taken control measures at source, established and improved the environmental management system, and implemented the requirements related to environmental safety in all of our key business activities, to reduce the environmental risks. 6. Foreign exchange risk Export sales constitute a large proportion of our total sales revenue. Because our day-to-day operation involves transactions in USD and other foreign currencies, and our consolidated accounts are presented in RMB, the changes in the exchange rate between RMB and USD may cause foreign exchange risk to our future operations. We will pay close attention to the changes in the relevant foreign exchange rates, strive to control the exposure to foreign exchange risk at a reasonable level, and hedge or otherwise reduce exposure to such risk. 7. Quality control risk of auto parts products The new energy automobile industry in which we are engaged is subject to a strict quality management and product certification system. Vehicle manufacturers have extremely high requirements for the quality and safety of auto parts products, taking product quality as an important indicator for them to choose auto parts suppliers. 27 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 In response, we will improve the construction of a quality management system, strictly control the procurement of raw materials, production process and product testing, and establish a sound traceability mechanism, for the sake of timely recall and handling in case of problems. Meanwhile, we will have closer cooperation with and strengthen supervision over suppliers to ensure stable and reliable quality of auto parts. XI.

Accounting treatment of business combinations involving entities under common control and not under common control (1) Accounting treatment of business combinations involving entities under common control Assets and liabilities acquired from a business combination by the Company are measured at the carrying value of the assets and liabilities of the acquiree in the consolidated financial statements of the ultimate controller at the combination date. The difference between the carrying value of the owners’ equity of the acquiree as stated in the consolidated financial statements of the ultimate controller and the carrying value of the total consideration paid or total par value of the shares issued in connection with the combination is treated as an adjustment to the capital reserve. In case the capital reserve is not sufficient to absorb the difference, the remaining balance is charged against the retained earnings. (2) Accounting treatment of business combinations involving entities not under common control Where the cost of the combination exceeds the Company’s share of the fair value of the acquiree’s net identifiable assets, the difference is recognized as goodwill at the acquisition date. Where the cost of combination is lower than the Company’s share of the fair value of the acquiree’s net identifiable assets, the Company reviews the measurement of the fair value of each of the identifiable assets, liabilities and contingent liabilities acquired from the acquiree and the cost of combination, and if the cost of combination as reviewed is still lower than the Company’s share of the fair value of the acquiree’s net identifiable assets, the difference is recognized in profit or loss. 7. Determination of control and method of preparation of consolidated financial statements (1) Determination of control Control means that the Company has power over the investee, exposure or rights to variable returns from its involvement with the investee and the ability to use its power to affect the amount of those returns. 79 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 (2) Method of preparation of consolidated financial statements The parent includes all of its controlled subsidiaries in its consolidated financial statements. The consolidated financial statements are prepared by the parent in accordance with CASBE 33 “Consolidated Financial Statements”, on the basis of the respective financial statements of the parent and its subsidiaries, by reference to other relevant data. 8. Classification of joint arrangements and accounting treatment of joint operations (1) Joint arrangements are classified as joint operations and joint ventures. (2) When the Company is a party to a joint operation, the Company recognizes the following items relating to its interest in the joint operation: 1) the assets individually held by the Company, and the Company’s share of the assets held jointly. 2) the liabilities incurred individually by the Company, and the Company’s share of the liabilities incurred jointly. 3) the Company’s revenue from the sale of its share of the output of the joint operation. 4) the Company’s share of revenue from the sale of assets by the joint operation. 5) the expenses incurred individually by the Company, and the Company’s share of the expenses incurred jointly. 9. Recognition of cash and cash equivalents For the purpose of the statement of cash flows, cash comprises cash on hand and demand deposits, and cash equivalents comprise short-term, highly liquid investments that are readily convertible into known amounts of cash and which are subject to an insignificant risk of changes in value. 10. Translation of foreign currency transactions and foreign currency financial statements (1) Translation of foreign currency transactions Upon initial recognition, foreign currency transactions are translated into RMB using the approximate exchange rates of spot exchange rates at the transaction dates. At the balance sheet date, monetary items denominated in foreign currencies are translated into RMB using the spot exchange rates then prevailing. Exchange differences arising from such translations are recognized in profit or loss, except for those attributable to foreign currency borrowings that have been taken out specifically for the acquisition or construction of qualifying assets and accrued interest. Non-monetary items denominated in foreign currencies that are measured at historical cost are translated using the approximate exchange rates of spot exchange rates at the transaction dates, without adjusting the amounts 80 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 in RMB. Non-monetary items denominated in foreign currencies that are measured at fair value are translated using the foreign exchange rates prevailing at the dates the fair value was determined, with the exchange differences arising from such translations recognized in profit or loss or other comprehensive income. (2) Translation of foreign currency financial statements The asset and liability items in the balance sheet are translated at the spot exchange rates prevailing at the balance sheet date. The owners’ equity items other than “retained profits” are translated at the spot exchange rates prevailing at the transaction dates. The income and expense items in the income statement are translated at the approximate exchange rates of spot exchange rates at the transaction dates. The differences arising from such translation of foreign currency financial statements are recognized in other comprehensive income. 11. Financial instruments 1. Classification of financial assets and financial liabilities Upon initial recognition, financial assets are classified as: (i) financial assets at amortized cost; (ii) financial assets at fair value through other comprehensive income; and (iii) financial assets at fair value through profit or loss. Upon initial recognition, financial liabilities are classified as: (i) financial liabilities at fair value through profit or loss; (ii) financial liabilities arising as a result of the transfer of financial assets not meeting the criteria for derecognition or continuing involvement in the financial assets transferred; (iii) financial guarantee contracts not falling under items (i) and (ii), and loan commitments not falling under item (i) and below market interest rate; and (iv) financial liabilities at amortized cost. 2. Recognition, measurement and derecognition of financial assets and financial liabilities (1) Recognition and initial measurement of financial assets and financial liabilities When the Company becomes a party to a financial instrument contract, a financial asset or liability is recognized. Financial assets and liabilities are initially measured at fair value. Transaction costs relating to financial assets or liabilities at fair value through profit or loss are directly recognized in profit or loss. Transaction costs relating to other kinds of financial assets or liabilities are included in their initially recognized amount. However, the accounts receivable that do not contain any significant financing component or are recognized by the Company without taking into consideration the significant financing components under the contracts with a term of less than one year upon initial recognition are initially measured at transaction price as defined in CASBE 14 “Revenue”. (2) Subsequent measurement of financial assets 1) Financial assets at amortized cost 81 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 Financial assets at amortized cost are subsequently measured at amortized cost using the effective interest method. Gains or losses on financial assets at amortized cost that do not belong to any hedging relationship are recognized in profit or loss upon derecognition, reclassification, amortization using the effective interest method, or recognition of impairment. 2) Investments in debt instruments at fair value through other comprehensive income Investments in debt instruments at fair value through other comprehensive income are subsequently measured at fair value. Interest, impairment losses or gains and exchange gains or losses calculated using the effective interest method are recognized in profit or loss, while other gains or losses are recognized in other comprehensive income. Upon derecognition, the aggregate gains or losses previously recognized in other comprehensive income are transferred to profit or loss. 3) Investments in equity instruments at fair value through other comprehensive income Investments in equity instruments at fair value through other comprehensive income are subsequently measured at fair value. Dividends received (other than those received as recovery of investment cost) are recognized in profit or loss, while other gains or losses are recognized in other comprehensive income. Upon derecognition, the aggregate gains or losses previously recognized in other comprehensive income are transferred to retained earnings. 4) Financial assets at fair value through profit or loss Financial assets at fair value through profit or loss are subsequently measured at fair value. Gains or losses thereon, including interest and dividend income, are recognized in profit or loss, except the financial assets belonging to any hedging relationship. (3) Subsequent measurement of financial liabilities 1) Financial liabilities at fair value through profit or loss Financial liabilities at fair value through profit or loss include financial liabilities held for trading (including derivatives classified as financial liabilities), and financial liabilities directly designated as at fair value through profit or loss. Such financial liabilities are subsequently measured at fair value. Changes in the fair value of financial liabilities designated as at fair value through profit or loss arising out of changes in the Company’s credit risk are recognized in other comprehensive income, unless such treatment will result in or increase any accounting mismatch in profit or loss. Other gains or losses on such financial liabilities, including interest expenses and changes in fair value not arising out of changes in the Company’s credit risk, are recognized in profit or loss, except the financial liabilities belonging to any hedging relationship. Upon derecognition, the aggregate gains or losses previously recognized in other comprehensive income are transferred to retained earnings. 82 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 2) Financial liabilities arising as a result of the transfer of financial assets not meeting the criteria for derecognition or continuing involvement in the financial assets transferred Such financial liabilities are measured in accordance with CASBE 23 “Transfer of Financial Assets”. 3) Financial guarantee contracts not falling under items 1) and 2), and loan commitments not falling under item 1) and below the market interest rate Such financial liabilities are subsequently measured at the higher of (i) allowance for impairment losses determined according to the policy for impairment of financial instruments; and (ii) balance of the initially recognized amount after deduction of the accumulated amortization determined in accordance with CASBE 14 “Revenue”. 4) Financial liabilities at amortized cost Financial liabilities at amortized cost are subsequently measured at amortized cost using the effective interest method. Gains or losses on financial liabilities at amortized cost that do not belong to any hedging relationship are recognized in profit or loss upon derecognition or amortization using the effective interest method. (4) Derecognition of financial assets and financial liabilities 1) Financial assets are derecognized when: ① the contractual right to receive cash flows from the financial assets has expired; or ② the financial assets have been transferred and such transfer meets the criteria for derecognition of financial assets as set forth in CASBE 23 “Transfer of Financial Assets”. 2) A financial liability (or part thereof) is derecognized when all or part of the outstanding obligations thereunder have been discharged. 3. Determination and measurement of financial assets transferred When a financial asset of the Company is transferred, if substantially all the risks and rewards incidental to the ownership of the financial asset have been transferred, the financial asset is derecognized, and the rights and obligations incurred or retained in such transfer are separately recognized as assets or liabilities (as the case may be); if the Company has retained substantially all the risks and rewards incidental to the ownership of the financial asset, the Company continues to recognize the financial asset transferred. If the Company neither transferred nor retained a substantial portion of all risks and rewards incidental to the ownership of the financial asset, then: (i) if the Company does not retain control over the financial asset, the financial asset is derecognized, and the rights and obligations incurred or retained in such transfer are separately recognized as assets or liabilities (as the case may be); or (ii) if the Company retains control over the financial asset, the financial asset continues to be recognized to 83 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 the extent of the Company’s continuing involvement in the financial asset transferred, and a corresponding liability is recognized. If an entire transfer of a financial asset meets the criteria for derecognition, the difference between (i) the carrying value of the financial asset transferred at the date of derecognition; and (ii) the sum of the consideration received from the transfer and the portion of the cumulative amount of changes in fair value directly recorded as other comprehensive income originally that corresponds to the part derecognized (where the financial asset transferred is an investment in debt instruments at fair value through other comprehensive income) is recognized in profit or loss. If part of a financial asset is transferred and the part transferred entirely meets the criteria for derecognition, the total carrying value of the financial asset immediately prior to the transfer is allocated between the part derecognized and the part not derecognized in proportion to their relative fair value at the date of transfer, and the difference between (i) the carrying value of the part derecognized; and (ii) the sum of the consideration received from the transfer of the part derecognized and the portion of the cumulative amount of changes in fair value directly recorded as other comprehensive income originally that corresponds to the part derecognized (where the financial asset transferred is an investment in debt instruments at fair value through other comprehensive income) is recognized in profit or loss. 4. Determination of fair value of financial assets and financial liabilities The Company adopts the valuation techniques applicable to the current situations and with sufficient data available and support of other information, to determine the fair value of financial assets and financial liabilities. The Company classifies the inputs used by the valuation techniques in the following levels and uses them in turn: (1) Level 1 inputs: quoted market price (unadjusted) in an active market for an identical asset or liability available at the date of measurement. (2) Level 2 inputs: inputs other than inputs included within Level 1 that are observable directly or indirectly. This category includes quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, observable inputs other than quoted prices (such as interest rate and yield curves observable during regular intervals of quotation), and inputs validated by the market. (3) Level 3 inputs: inputs that are unobservable. This category includes interest rate or stock volatility that cannot be directly observed or validated by observable market data, future cash flows from retirement obligations incurred in business combinations, and financial forecasts made using own data. 5. Impairment of financial instruments The Company determines the impairment and assesses allowance for impairment of financial assets at amortized cost, investments in debt instruments at fair value through other comprehensive income, contract assets, lease 84 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 payments receivable, loan commitments other than financial liabilities designated at fair value through profit or loss, and financial guarantee contracts other than financial liabilities designated at fair value through profit or loss and financial liabilities arising as a result of the transfer of financial assets not meeting the criteria for derecognition or continuing involvement in the financial assets transferred, on the basis of expected credit losses. Expected credit loss is the weighted average of credit losses on financial instruments taking into account the possibility of default. Credit loss is the present value of the difference between all contractual cash flows receivable under the contract and estimated future cash flows discounted at the original effective interest rate, i.e. the present value of all cash shortages, where the Company’s purchased or originated financial assets that have become credit impaired are discounted at their credit-adjusted effective interest rate. With respect to purchased or originated financial assets that have become credit impaired, at the balance sheet date, the Company recognizes an impairment loss equal to the cumulative amount of changes in lifetime expected credit losses since initial recognition. With respect to lease payments receivable, accounts receivable arising from transactions within the meaning of CASBE 14 “Revenue”, the Company uses the simplified measurement method and recognizes an impairment loss equal to the lifetime expected credit losses. With respect to financial assets not using the measurement methods stated above, at each balance sheet date, the Company assesses whether the credit risk has increased significantly since initial recognition, and recognizes an impairment loss equal to the lifetime expected credit losses if the credit risk has increased significantly since initial recognition, or to the expected credit losses within the next 12 months if the credit risk has not increased significantly since initial recognition. The Company uses reasonable and supportable information, including forward-looking information, and compares the possibility of default at the balance sheet date with the possibility of default upon initial recognition, to determine whether the credit risk of the financial instruments has increased significantly since initial recognition. At the balance sheet date, if the Company determines that a financial instrument has low credit risk, the Company assumes that its credit risk has not increased significantly since initial recognition. The Company assesses expected credit risk and measures expected credit losses of financial instruments individually or collectively. When assessing the financial instruments collectively, the Company includes the financial instruments in different groups according to their common risk characteristics. At each balance sheet date, the Company re-assesses the expected credit losses, with the amount of increase in or reversal of impairment loss recognized in profit or loss as impairment losses or gains. With respect to a financial 85 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 asset at amortized cost, its carrying value recorded in the balance sheet is written off against the impairment loss. With respect to an investment in debt instruments at fair value through other comprehensive income, the Company recognizes the impairment loss in other comprehensive income, without reducing its carrying value. 6. Offsetting of financial assets and financial liabilities Financial assets and financial liabilities are offset and presented on a net basis in the balance sheet only if: (i) the Company has a currently enforceable legal right to offset the recognized amounts; and (ii) the Company has an intention to settle on a net basis or realize the assets and settle the liabilities simultaneously. Except as stated above, financial assets and financial liabilities are presented in the balance sheet separately, without offsetting each other. With respect to the transfer of financial assets not meeting the criteria for derecognition, the Company does not offset the financial assets transferred against the relevant liabilities. 12. Notes receivable 13. Accounts receivable 14. Accounts receivable financing 15. Other receivables 16. Contract assets Contract assets or contract liabilities are presented in the balance sheet according to the relationship between the relevant performance obligations and payment by the customer. Contract assets and contract liabilities under the same contract are presented on a net basis. The right of the Company to payment that is unconditional, except for the passage of time, is presented as an account receivable. The right of the Company to payment for goods already transferred to a customer is presented as a contract asset if that right to payment is conditional on something other than the passage of time. The Company’s obligation to transfer goods to a customer in exchange for the consideration paid or payable by the customer is presented as a contract liability. 17. Inventories 1. Classification of inventories Inventories include finished products or goods held for sale in the ordinary course of business, work in progress and materials and goods consumed in the process of production or rendering of services. 86 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 2. Valuation of inventories dispatched The value of inventories dispatched is determined using the weighted average method at the end of the month in which they were dispatched. 3. Inventory system The perpetual inventory system is adopted. 4. Amortization of low-value consumables and packing materials (1) Low-value consumables Low-value consumables are amortized using the immediate write-off method. (2) Packing materials Packing materials are amortized using the immediate write-off method. 5. Inventory provision At the balance sheet date, inventories are measured at the lower of cost and net realizable value. An amount equal to the cost of an inventory in excess of its net realizable value is recognized as an inventory provision. The net realizable value of inventories held directly for sale is the estimated selling price of such inventories less the estimated selling expenses and related taxes in the ordinary course of business. The net realizable value of inventories to be further processed is the estimated selling price of finished goods less the estimated cost of completion, estimated selling expenses and related taxes in the ordinary course of business. At the balance sheet date, if part of an inventory has a contract price while the remaining part thereof does not have a contract price, the net realizable value is determined separately, which is compared with their cost, to determine the amount of the inventory provision recognized or reversed (as applicable). 18. Assets held for sale 19. Debt investments 20. Other debt investments 21. Long-term receivable 22. Long-term equity investments 1. Determination of joint control and significant influence Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control. Significant influence is the 87 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 power to participate in the financial and operating policy-making of an entity, but is not control or joint control over those policies. 2. Determination of investment cost (1) For an equity investment acquired through a business combination involving entities under common control, if the acquirer pays consideration for the business combination by cash, transfer of non-monetary assets, assumption of liabilities or issuance of equity securities, the initial investment cost of the long-term equity investment is the Company’s share of the carrying value of the owners’ equity of the acquiree in the consolidated financial statements of the ultimate controller at the combination date. The difference between: (i) the initial investment cost of the long- term equity investment; and (ii) the carrying value of the consideration paid for the combination or the total par value of the shares issued (as applicable) is treated as an adjustment to the capital reserve. In case the capital reserve is not sufficient to absorb the difference, the remaining balance is charged against the retained earnings. If a business combination is affected through multiple transactions by steps that constitute a package deal, the Company accounts for such transactions as one deal to gain control. If such transactions do not constitute a package deal, the initial investment cost is the Company’s share of the carrying value of the owners’ equity of the acquiree in the consolidated financial statements of the ultimate controller at the combination date; and the difference between: (i) the initial investment cost of the long-term equity investment at the combination date; and (ii) the sum of the carrying value of long-term equity investment before the combination and the carrying value of the consideration paid for acquisition of the additional shares at the combination date is treated as an adjustment to the capital reserve. In case the capital reserve is not sufficient to absorb the difference, the remaining balance is charged against the retained earnings. (2) For an equity investment acquired through a business combination involving entities not under common control, the initial investment cost is the fair value of the aggregate consideration paid at the date of acquisition. With respect to a long-term equity investment acquired through a business combination involving entities under common control that is affected through multiple transactions by steps, the accounting thereof in the standalone financial statements is different from that in the consolidated financial statements as stated below: 1) In the standalone financial statements, the sum of the carrying value of the equity investment originally held in the acquiree and the additional investment cost incurred is recorded as the initial investment cost of the equity investment changed into the cost method. 2) In the consolidated financial statements, if the transactions constitute a package deal, the Company accounts for such transactions as one deal to gain control. If such transactions do not constitute a package deal, the equity held 88 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 in the acquiree prior to the acquisition date is remeasured at its fair value at the acquisition date, with the difference between its fair value and carrying value recognized as an investment income for the current period; if the equity held in the acquiree prior to the acquisition date involves other comprehensive income under the equity method, such other comprehensive income is transferred to the income for the period in which the acquisition date falls, except for other comprehensive income arising from remeasurement of changes in net liabilities or net assets of defined benefit plans. (3) For an equity investment not acquired through business combination, the initial investment cost is the purchase price actually paid if it is acquired by cash, or the fair value of the equity securities issued if it is acquired through issuance of equity securities, or in accordance with CASBE 12 “Debt Restructuring” if it is acquired through debt restructuring, or CASBE 7 “Exchange of Non-monetary Assets” if it is acquired through exchange of non-monetary assets. 3. Subsequent measurement and recognition of profit or loss Long-term equity investments in investees over which the Company exercises control are accounted for using the cost method. Long-term equity investments in associates and joint ventures are accounted for using the equity method. 4. Disposal of investment in a subsidiary through multiple transactions by steps until loss of control over the subsidiary (1) Criteria for determining a package deal Where the Company loses control over a subsidiary due to the disposal of equity investment in the subsidiary through multiple transactions by steps, the Company determines whether such transactions constitute a package deal taking into account the transaction contract terms, consideration received, the transferee of the equity sold, method of disposal, time of disposal and other information in respect of each step. If the terms, conditions and financial effect of such transactions fall under one or more of the circumstances set forth below, such transactions are accounted for as a package deal generally: 1) such transactions are concluded simultaneously or in consideration of their mutual effect. 2) such transactions will achieve a complete business result only as a whole. 3) the occurrence of a transaction depends on the occurrence of at least another transaction; and/or 4) a transaction may be uneconomical when considered individually, but is economical when considered together with other transactions. (2) Accounting treatment of transactions not constituting a package deal 89 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 1) Standalone financial statements The difference between the carrying value of the equity disposed of and the disposal proceeds actually received is recognized in profit or loss. If the remaining equity empowers the Company to exercise significant influence or joint control over the investee, the remaining equity is accounted for using the equity method; if the remaining equity does not empower the Company to exercise control, joint control or significant influence over the investee, the remaining equity is accounted for in accordance with CASBE 22 “Recognition and Measurement of Financial Instruments”. 2) Consolidated financial statements Before the loss of control, the difference between the disposal proceeds and the Company’s share of the net assets of the subsidiary corresponding to the long-term equity investment disposed of as calculated continuously from the acquisition date or combination date is treated as an adjustment to the capital reserve (capital premium). In case the capital premium is not sufficient to absorb the difference, the remaining balance is charged against the retained earnings. Upon loss of control, the remaining equity is remeasured at its fair value at the date of loss of control. The sum of the consideration received from the disposal of the equity and the fair value of the remaining equity, net of the Company’s share of the net assets of the subsidiary as calculated continuously from the acquisition date according to the original shareholding ratio, is included in the investment income for the period during which the control was lost, and charged against goodwill. Other comprehensive income related to the equity investment in the subsidiary is transferred to the investment income for the period during which the control was lost. (3) Accounting treatment of transactions constituting a package deal 1) Standalone financial statements The Company accounts for such transactions as one deal to dispose of and lose control over the subsidiary; however, in the standalone financial statements, the difference between the proceeds from each disposal before loss of control and the carrying value of the long-term equity investment corresponding to the equity disposed of is recognized in other comprehensive income, which is wholly transferred to profit or loss in the period during which the control was lost. 2) Consolidated financial statements The Company accounts for such transactions as one deal to dispose of and lose control over the subsidiary; however, in the consolidated financial statements, the difference between the proceeds from each disposal before loss of control and the Company’s share of the net assets of the subsidiary corresponding to the equity disposed of is 90 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 recognized in other comprehensive income, which is wholly transferred to profit or loss in the period during which the control was lost. 23. Investment property 1. Investment properties include land use rights leased out or held for appreciation and buildings and structures leased out. 2. An investment property is measured initially at cost, and subsequently using the cost model, and depreciated or amortized using the same method as fixed assets and intangible assets. 24. Fixed assets (1) Criteria for recognition Fixed assets are tangible assets held for the production of goods, rendering of service, lease or operation and management with a useful life of more than one accounting year. A fixed asset is recognized if the economic benefits relating to it are very likely to flow to the Company and its cost can be reliably measured. (2) Depreciation Estimated useful life Rate of residual value Annual rate of Category Method of depreciation (years) (%) depreciation Buildings and Straight line method 20-30 5 3.17-4.75 structures Machinery and Straight line method 5-10 5 9.50-19.00 equipment Transportation Straight line method 5 5 19.00 equipment Office equipment and Straight line method 5 5 19.00 others 25. Construction in progress 1. A construction in progress is recognized if the economic benefits relating to it are very likely to flow to the Company and its cost can be reliably measured. Construction in progress is measured at the actual cost incurred before it is completed and ready for the intended use. 2. When a construction in progress is ready for intended use, it is transferred to fixed assets at its actual construction cost. A construction in progress that is ready for intended use but the final settlement of which has not yet been completed is transferred to fixed assets at estimated value first, and after the completion of the final settlement, the estimated value is adjusted according to the actual cost, without adjusting the accumulated depreciation. 91 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 Category Criteria and time for transfer of construction in progress to fixed assets Meet the design requirements or agreed standards after installation and Machinery and equipment commissioning Buildings and structures Meet the building completion acceptance criteria 26. Borrowing costs 1. Recognition of capitalization of borrowing costs Borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset are capitalized as part of the cost of the asset when they meet the condition for capitalization. Other borrowing costs are expensed when they are incurred and recognized in profit or loss. 2. Period of capitalization of borrowing costs (1) A borrowing cost is capitalized when all of the following conditions are satisfied: (i) the expenditures on the asset have already been incurred; (ii) the borrowing cost has already been incurred; and (iii) the acquisition, construction or production activities necessary to prepare the asset for its intended use or sale have already commenced. (2) Capitalization of borrowing costs is suspended during the period of abnormal interruption of acquisition, construction or production of a qualifying asset which lasts for more than three consecutive months. The borrowing costs incurred during the period of suspension are recognized as expenses for the current period. The capitalization of borrowing costs is suspended until the resumption of acquisition, construction or production activities. (3) Capitalization of borrowing costs ceases when a qualifying asset acquired, constructed or produced gets ready for its intended use or sale. 3. Rate and amount of capitalization of borrowing costs For borrowings obtained specially for the acquisition, construction or production of a qualifying asset, the amount of capitalization of the borrowing costs is the cost of the borrowings actually incurred in the current period (including amortized discount or premium determined using the effective interest method) less the interest income from the part of borrowings that has not yet been utilized and is deposited in banks or investment income from temporary investment of the borrowings. For general borrowings occupied for the acquisition, construction or production of a qualifying asset, the amount of borrowing costs eligible for capitalization is determined by multiplying the weighted average of the excess of cumulative expenditures on the asset over the special-purpose borrowings by the capitalization rate of the general borrowings occupied. 92 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 27. Biological assets 28. Oil and gas assets 29. Intangible assets (1) Useful life and basis for determination of useful life, estimates, method of amortization or review procedure 1. Intangible assets, including land use rights, patents, non-patent technologies, etc., are initially measured at cost. 2. An intangible asset with a finite useful life is amortized in a systematic and reasonable manner according to the pattern in which the economic benefits related to the intangible asset are expected to be realized, or if that pattern cannot be determined reliably, using the straight-line method as follows: Useful life and basis for determination of Method of Item useful life (years) amortization Land use rights 50 Straight line method Development expenses 5 Straight line method Software 3 Straight line method Trademarks and patents 10 Straight line method Customer resources 10 Straight line method Intangible asset with indefinite useful life is not amortized, but its useful life is reviewed annually. (2) Scope and accounting treatment of research and development (R&D) expenses 3. Scope of R&D expenses (1) Labor costs Labor costs comprise the wages, salaries, basic pension insurance, basic medical insurance, unemployment, worker’s compensation insurance, maternity insurance and housing provident fund contributions paid to or for the R&D personnel, and service fees of the outsourced R&D personnel. With respect to the R&D personnel serving a number of R&D projects concurrently, their labor costs are allocated to the relevant R&D projects on a pro-rata basis according to the record of working hours spent by them in such R&D projects as provided by the administrative department. With respect to the Company’s own R&D personnel and outsourced R&D personnel who are directly engaged in R&D activities and also engaged in non-R&D activities, their labor costs actually incurred are allocated between R&D expenses and production and business expenses on a pro-rata basis in proportion to the percentage of working hours spent by them on different posts as recorded, or otherwise reasonably. (2) Direct costs 93 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 Direct costs refer to the costs actually incurred by the Company in connection with R&D activities, including (i) costs of materials, fuels and powers directly consumed; (ii) costs of development and fabrication of molds and process equipment used in pilot trials and trial production, purchasing costs of samples, prototypes and general testing methods not classified as fixed assets, and inspection costs of trial produces; and (iii) operation, maintenance, calibration, inspection, testing, repair and other costs of instruments and equipment used in R&D activities. (3) Depreciation expenses and long-term deferred expenses Depreciation expenses refer to the depreciation expenses of instruments, equipment and buildings used in R&D activities. With respect to the instruments, equipment and buildings used in both R&D activities and non-R&D activities, the depreciation expenses actually incurred are allocated between R&D expenses and production and business expenses according to the actual working hours and area used as recorded, or otherwise reasonably. Long-term deferred expenses refer to the long-term deferred expenses incurred in the alteration, modification, renovation and repair of R&D facilities, which are recorded according to the amounts actually spent, and amortized on a straight-line basis over the defined period. (4) Amortization expenses of intangible assets Amortization expenses of intangible assets refer to the amortization expenses of software, intellectual properties, and non-patented technologies (know-how, licenses, designs, computing methods, etc.) used in R&D activities. (5) Design costs Design costs refer to the costs incurred in the design of processes, technical specifications, rules of operation and operating features in connection with the concept, development and manufacturing of new products and new processes, including the costs of creative design activities conducted for the purpose of developing innovative, creative and breakthrough products. (6) Equipment commissioning costs and testing costs Equipment commissioning costs refer to the costs incurred during the equipment preparation phase of R&D activities, including the costs of developing special-purpose production machines, changing production and quality control procedures, developing new approaches and standards, etc. The costs incurred for general equipment preparation and industrial engineering in connection with large-scale mass and commercial production are excluded from the scope of aggregation. Testing costs include clinical trial costs for the development of new drugs, field trial costs for exploration and development technologies, field experiment costs, etc. 94 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 (7) Outsourced R&D expenses Outsourced R&D expenses refer to the expenses of R&D activities that the Company engages external entities or individuals at home or abroad to conduct, provided that the results of such R&D activities will be owned by the Company and such R&D activities are closely related to the primary business of the Company. (8) Other expenses Other expenses refer to the expenses that are not set forth above and directly related to R&D activities, including the expenses of technical documents and data, translation, advisors and consultants, high and new technology R&D insurance, retrieval, verification, evaluation, appraisal and acceptance inspection of R&D achievements, application, registration and agency service in respect of intellectual properties, meetings, travel, communication, etc. 4. Expenditures on an internal R&D project at the research phase are recognized in profit or loss in the period in which they are incurred. Expenditures on an internal R&D project at the development phase are recognized as an intangible asset if: (i) it is technically feasible to complete the intangible asset so that it will be available for use of sale; (ii) it is intended to complete the intangible asset so that it will be available for use of sale; (iii) the pattern in which the intangible asset will generate economic results can demonstrate the existence of a market for the output of the intangible asset or the intangible asset itself, or if it is to be used internally, the usefulness of the intangible asset; (iv) there are sufficient technical, financial and other resources available to complete the development activities and to use or sell the intangible asset; and (v) the expenditures attributable to the development of the intangible asset can be reliably measured. 30. Impairment of long-term assets With respect to long-term equity investments, investment properties at cost, fixed assets, construction in progress, productive biological assets at cost, oil and gas assets, right-of-use assets, intangible assets with a finite useful life and other long-term assets, if there’s an indication of impairment at the balance sheet date, the Company assesses their recoverable amount. Goodwill arising from business combinations and intangible assets with an infinite useful life are tested for impairment every year regardless of whether there’s an indication of impairment. Goodwill is tested for impairment together with the relevant groups of assets or combinations of groups of assets. If the recoverable amount of a long-term asset is less than its carrying value, the difference is measured as an impairment loss on the asset and recognized in profit or loss. 95 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 31. Long-term deferred expenses Long-term deferred expenses are expenses that have already been incurred but should be amortized over a period of more than one year. Long-term deferred expenses are stated as the amount actually incurred, and equally amortized over the benefit period or established period. If an item of long-term deferred expenses will not benefit the subsequent periods, the remaining unamortized balance of the item is wholly transferred to profit or loss. 32. Contract liabilities Contract assets or contract liabilities are presented in the balance sheet according to the relationship between the relevant performance obligations and payment by the customer. Contract assets and contract liabilities under the same contract are presented on a net basis. The Company’s rights to receive consideration from customers unconditionally (which depends only on the passage of time) are presented as receivables, and the Company’s rights to receive consideration for goods transferred to customers (which depends on factors other than the passage of time) are presented as contract assets. The Company’s obligation to transfer goods to a customer in exchange for the consideration paid or payable by the customer is presented as a contract liability. 33. Employee benefits (1) Accounting treatment of short-term employee benefits 1. Employee benefits include short-term employee benefits, post-employment benefits, termination benefits and other long-term employee benefits. 2. Accounting treatment of short-term employee benefits The short-term employee benefits actually incurred are recognized as liabilities in the accounting period during which employee services are rendered and included in profit or loss or the cost of related assets. (2) Accounting treatment of post-employment benefits Post-employment benefits are classified as defined contribution plans and defined benefit plans. (1) In the accounting period during which employee services are rendered, the amount contributable as calculated according to the defined contribution plan is recognized as liabilities and included in profit or loss or the costs of related assets. (2) The accounting treatment of a defined benefit plan generally involves the following steps: 96 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 1) According to the projected unit credit method, use unbiased and consistent actuarial assumptions to estimate demographic variables and financial variables, measure the obligation arising from the defined benefit plan and determine the period to which the relevant obligation belongs. Meanwhile, discount the obligation arising from the defined benefit plan, in order to determine the present value of the benefit plan obligation and the current service cost. 2) If the defined benefit plan has assets, the deficit or surplus resulting after reducing the present value of the defined benefit obligation by the fair value of the defined benefit plan is recognized as a net liability or asset of the defined benefit plan. If the defined benefit plan has a surplus, the net assets of the defined benefit plan are measured at the lower of surplus in the defined benefit plan and asset ceiling. 3) At the end of the current period, the cost of employee benefits arising from the defined benefit plan is recorded as service cost, net interest on the net liabilities or net assets of the defined benefit plan, and changes arising from remeasurement of the net liabilities or net assets of the defined benefit plan, where the service cost and the net interest on the net liabilities or net assets of the defined benefit plan are included in profit or loss or the cost of related assets, and the changes arising from remeasurement of the net liabilities or net assets of the defined benefit plan are included in other comprehensive income, which will not be reversed to profit or loss in subsequent periods, but may be transferred within the scope of equity. (3) Accounting treatment of termination benefits When the Company can no longer withdraw the offer of termination benefits as a result of termination of employment or redundancy, or recognizes the restructuring costs or expenses relating to payment of termination benefits, whichever the earlier, the employee benefit liabilities arising from recognition of termination benefits are recognized in profit or loss. (4) Accounting treatment of other long-term employee benefits Other long-term employee benefits are accounted for in accordance with the provisions applicable to defined contribution plans if they are qualified as defined contribution plans, otherwise, are accounted for in accordance with the provisions applicable to defined benefit plans. In order to simplify the accounting, the total net amount of the cost of employee benefits arising from the defined benefit plans that is recorded as service cost, net interest on the net liabilities or net assets of the defined benefit plan, changes arising from remeasurement of the net liabilities or net assets of the defined benefit plan and other components is included in profit or loss or the cost of related assets. 97 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 34. Provisions 1. Provisions are recognized when the Company has a present obligation as a result of any external guarantee, litigations, product quality warranty, onerous contract or other contingencies, and it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and the amount of the obligation can be reliably measured. 2. Provisions are initially measured according to the best estimates of the expenditures required to settle the related present obligations. The carrying value of provisions is reviewed at the balance sheet date. 35. Share-based payments 1. Types of share-based payments Share-based payments include equity-settled share-based payments and cash-settled share-based payments. 2. Accounting treatment of implementation, amendment and termination of share-based payment plans (1) Equity-settled share-based payment With respect to an equity-settled share-based payment that is granted in exchange for the services of employees, if the right can be immediately exercised after the grant, at the date of the grant, the fair value of the equity instruments is included in the relevant costs or expenses, and the capital reserve is adjusted accordingly; if the right may not be exercised until the vesting period comes to an end or until the specified performance conditions are met, at each balance sheet date within the vesting period, the services received in the current period are, based on the best estimate of the exercisable equity, included in the relevant costs or expenses at the fair value of the equity instruments at the date of grant, and the capital reserve is adjusted accordingly. An equity-settled share-based payment that is granted in exchange for the services of any other party is measured at fair value at the date of receipt of such services if the fair value of such services can be reliably measured, or at the fair value of the equity instruments at the date of receipt of such services if the fair value of such services cannot be reliably measured but the fair value of the equity instruments can be reliably measured. The services are included in the relevant costs or expenses, and the owners’ equity is increased accordingly. (2) Cash-settled share-based payment With respect to a cash-settled share-based payment that is granted in exchange for the services of employees, if the right can be immediately exercised after the grant, at the date of grant, the fair value of the liability undertaken by the Company is included in the relevant costs or expenses, and the liabilities are increased accordingly; if the right 98 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 may not be exercised until the vesting period comes to an end or until the specified performance conditions are met, at each balance sheet date within the vesting period, the services received in the current period are, based on the best estimate about the exercisable right, included in the relevant costs or expenses and the corresponding liabilities at the fair value of the liability undertaken by the Company. (3) Amendment and termination of share-based payment plans If such amendment results in an increase in the fair value of the equity instruments granted, the Company recognizes a corresponding increase in the services received according to the increase in the fair value of the equity instruments. If such amendment results in an increase in the number of the equity instruments granted, the Company recognizes a corresponding increase in the services received according to the fair value of the additional equity instruments granted. If the Company amends the vesting conditions in a manner favorable to the employees, the Company will take into account the vesting conditions as amended in the accounting thereof. If such amendment results in a decrease in the fair value of the equity instruments granted, the Company continues to recognize the services received based on the fair value of the equity instruments at the date of grant, without taking into account the decrease in the fair value of the equity instruments. If such amendment results in a decrease in the number of the equity instruments granted, the portion of the equity instruments reduced is deemed canceled. If the Company amends the vesting conditions in a manner unfavorable to the employees, the Company will not take into account the vesting conditions as amended in the accounting thereof. If, during the vesting period, the Company cancels or settles any equity instruments granted (except for those canceled due to failure to satisfy the vesting conditions), such cancellation or settlement is treated as an acceleration of vesting, and the amount that would have been recognized in the remaining vesting period is recognized immediately. 36. Preferred shares, perpetual bonds and other financial instruments 37. Revenue Accounting policies for recognition and measurement of revenue disclosed by business type 1. Revenue recognition principle At contract commencement, the Company assesses a contract to identify each single performance obligation included in the contract and whether such performance obligation shall be satisfied over time or at a point in time. A performance obligation shall be satisfied over time if it meets one of the following conditions, otherwise, it shall 99 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 be satisfied at a point in time: (i) the customer simultaneously receives and consumes the benefits provided by the Company’s performance; (ii) the customer can control the work in process created during the Company’s performance; or (iii) the Company’s performance does not create the goods with an alternative use to the Company and the Company has an enforceable right to payment for performance completed to date. With respect to a performance obligation satisfied over time, the Company recognizes revenue over time by measuring the progress toward complete satisfaction of that performance obligation. If the Company is unable to reasonably measure the progress of a performance obligation, but expects to recover the costs incurred in satisfying the performance obligation, the Company recognizes revenue only to the extent of the costs incurred until such time that it can reasonably measure the progress of the performance obligation. With respect to a performance obligation satisfied at a point in time, the Company recognizes revenue when the customer obtains control of the relevant goods or services. In determining whether the customer has obtained control of any goods, the Company considers the following indicators: (i) the Company has a present right to payment for the goods, i.e. the customer presently is obliged to pay for the goods; (ii) the Company has transferred the legal title to the goods to the customer, i.e. the customer has the legal title to the goods; (iii) the Company has transferred physical possession of the goods to the customer, i.e. the customer physically possesses the goods; (iv) the Company has passed the significant risks and rewards of ownership of the goods to the customer, i.e. the customer has the significant risks and rewards of ownership of the goods; (v) the customer has accepted the goods; and (vi) other indicators showing that the customer has obtained control of the goods. 2. Revenue measurement principle (1) The Company measures revenue according to the transaction price allocated to each performance obligation. Transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring the relevant goods or services to a customer, excluding the amounts collected on behalf of third parties or expected to be returned to the customer. (2) If a contract has any variable consideration, the Company determines the best estimate of the variable consideration according to the expected value or the most likely amount, but the Company shall include in the transaction price some or all of an amount of variable consideration only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. (3) If a contract contains a significant financing component, the Company determines the transaction price according to the amount that the customer would have paid for the goods or services if it had paid cash when it obtained control 100 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 of the goods or services. The difference between such transaction price and the contract consideration is amortized over the term of the contract using the effective interest method. (4) If a contract includes two or more performance obligations, at contract commencement, the Company allocates the transaction price to each performance obligation on a relative standalone selling price basis. 3. Methods of revenue recognition The Company is primarily engaged in the sale of PCBs, LED display devices, touch panels and LCMs, precision components and other products, the revenues from which constitute performance obligations to be satisfied at a point in time. Revenue from sale of products on the domestic market is recognized when the Company has delivered the products to the agreed place of delivery which has been accepted by the customer, has received or has a present right to payment for the products, and it is probable that the economic benefits associated with the transaction will flow to the Company. Revenue from sale of products on the overseas market is recognized when the products delivered by the Company pursuant to the contract have been cleared through customs, and the Company has received the relevant export declaration form and bill of lading, has received or has a present right to payment for the products, and it is probable that the economic benefits associated with the transaction will flow to the Company. Different methods of revenue recognition and measurement for the same business type adopts different business models. 38. Contract costs Contract acquisition costs, i.e. the incremental cost of acquiring a contract, are recognized as an asset if they are expected to be recovered, and if the amortization period is no more than one year, are directly recorded in profit or loss in the period in which they are incurred. Contract performance costs, i.e. the costs of fulfilling a contract, are recognized as an asset if they are not addressed by the standards on inventories, fixed assets and intangible assets and meet all of the following conditions: 1. the costs relate directly to a contract or to an anticipated contract, including direct labor, direct material, manufacturing costs (or similar costs), costs that are explicitly chargeable to the relevant customer under the contract and other costs incurred solely in connection with the contract. 2. the costs enhance the resources of the Company that will be used in satisfying the performance obligations in the future; and 3. the costs are expected to be recovered. 101 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 The assets related to contract costs are amortized on the same basis as the recognition of revenues from goods or services related to such assets and recognized in profit or loss. The portion of the carrying value of an asset related to contract costs in excess of the remaining consideration receivable from the transfer of goods or services related to such asset less the estimated costs that are expected to be incurred is recognized as an impairment loss. If, as a result of changes in the factors of impairment in the previous periods, the remaining consideration receivable from the transfer of goods or service related to such asset less the estimated costs that are expected to be incurred exceeds the carrying value of such asset, the impairment loss is reversed through profit or loss, provided that the carrying value of the reversed asset shall not exceed its carrying value at the reversal date assuming such impairment loss were not recognized. 39. Government grants 1. Government grants are recognized if (i) the Company meets the conditions attached to the government grants; and (ii) the Company will receive the government grants. Government grants in the form of monetary assets are measured at the amount received or receivable. Government grants in the form of non-monetary assets are measured at fair value, or if their fair value is unavailable, at a nominal amount. 2. Determination and accounting treatment of government grants related to assets Government grants related to assets are government grants which are offered for purchasing, constructing or otherwise acquiring long-term assets as provided by the applicable government documents, or in the absence of such express provision in the applicable government documents, whose primary condition is that the Company should purchase, construct or otherwise acquire long-term assets. Government grants related to assets are offset against the carrying value of the relevant assets or recognized as deferred income. Government grants related to assets recognized as deferred income are included in profit or loss over the service life of the relevant assets on a reasonable and systemic basis. Government grants measured at nominal amount are directly recognized in profit or loss. In case of a sale, transfer, retirement or damage of the relevant assets before the end of the intended service life, the balance of the unallocated deferred income is transferred to profit or loss for the period in which the assets are disposed of. 3. Determination and accounting treatment of government grants related to income Government grants related to income are government grants other than those related to assets. Government grants related to both assets and income where it is difficult to make a distinction between the portion related to assets and the portion related to income are wholly classified as government grants related to income. Government grants 102 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 related to income as compensation for expenses or losses to be incurred in subsequent periods are recognized as deferred income and in the period for recognizing the relevant costs, expenses or losses, included in profit or loss or offset against the relevant costs. Government grants related to income as compensation for expenses or losses already incurred are directly included in profit or loss or offset against the relevant costs. 4. Government grants related to day-to-day operations of the Company are recognized in other income or offset against the relevant costs and expenses depending on the nature of economic business. Government grants not related to day-to-day operations of the Company are recognized in non-operating revenues or expenses. 5. Accounting treatment of policy loan interest subsidy If the financial authority directly appropriates any interest subsidy to the Company, the interest subsidy is recognized as a reduction in the borrowing cost. 40. Deferred tax assets and deferred tax liabilities 1. The difference between the tax base of an asset or liability and its carrying value, or in case of an item not recognized as an asset or liability whose tax base can be determined according to the applicable tax law, the difference between its tax base and carrying value, is recognized as a deferred tax asset or deferred tax liability according to the tax rate applicable to the period in which the asset or liability is expected to be recovered or settled. 2. Deferred tax assets are recognized to the extent of the amount of income tax payable that will be available in future periods against which deductible temporary differences are deductible. At the balance sheet date, deferred tax assets not recognized in previous periods are recognized if there’s conclusive evidence that it is probable that sufficient taxable income will be available in future periods against which the deductible temporary differences are deductible. 3. At the balance sheet date, the carrying value of deferred tax assets is reviewed and written down to the extent that it is no longer probable that sufficient taxable income will be available in future periods to allow the benefit of the deferred tax assets to be utilized. If it is probable that sufficient taxable income will be available, the amount of write-down is reversed. 4. The income taxes and deferred income taxes are included in profit or loss as income tax expenses or gains, except the income taxes arising from any: (i) business combination; or (ii) transaction or event directly recognized in owners’ equity. 5. Deferred income tax assets and deferred income tax liabilities are offset and presented on a net basis if: (i) the Company has a legal right to settle current tax assets and current tax liabilities on a net basis; and (ii) the deferred 103 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 tax assets and deferred tax liabilities relate to income taxes levied by the same tax authority on either the same taxable entity or different taxable entities which intend either to settle current tax assets and current tax liabilities on a net basis or to realize the assets and liabilities simultaneously, in each future period in which significant amounts of deferred tax assets or liabilities are expected to be reversed. 41. Leases (1) Accounting treatment of leases under which the Company is lessee 1. The Company as the lessee: At the lease commencement date, a lease that has a lease term of 12 months or less and does not contain a purchase option is a short-term lease. A lease of an asset with a low value when new is a lease of a low-value asset. Where the Company subleases or expects to sublease a leased asset, the original lease is not classified as a lease of a low- value asset. Except short-term leases and leases of low-value assets, at the lease commencement date, the Company recognizes right-of-use assets and lease liabilities for the lease. (1) Right-of-use assets A right-of-use asset is a lessee’s right to use an asset over the life of a lease. At the lease commencement date, a right-of-use asset is initially measured at cost, which comprises: (i) the amount of the lease liability initially measured; (ii) any lease payments made at or before the commencement date, less any lease incentives received; (iii) any initial direct costs incurred by the lessee; and (iv) estimated costs to be incurred by the lessee in dismantling and removing the underlying asset, restoring the site on which it is located or restoring the underlying asset to the condition required by the terms and conditions of the lease. The Company depreciates the right-of-use assets using the straight-line method. If it is reasonable to be certain that the ownership of an underlying asset can be acquired by the end of the lease term, the Company depreciates the right-of-use asset over its remaining useful life. Otherwise, the Company depreciates the right-of-use asset over the shorter of the lease term and its remaining useful life. (2) Lease liabilities At the lease commencement date, the Company measures a lease liability at the present value of the lease payments that have not been paid at that date. The present value of lease payments is determined using the interest rate implicit in the lease as the discount rate. If that rate cannot be readily determined, the lessee’s incremental borrowing rate is used. The difference between the lease payments and their present value is unrecognized financing costs. Interest 104 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 expenses are measured for each period within the lease term using the discount rate for determining the present value of lease payments, and recognized in profit or loss. Variable lease payments not included in the measurement of lease liabilities are recognized in profit or loss in the period during which they are incurred. At the lease commencement date, if there are changes in the in-substance fixed lease payments, amounts expected to be payable under residual value guarantee, the index or rate used to determine the lease payments, the result of an assessment of purchase option, renewal option or termination option or the actual exercise of such options, the Company re-measures the lease liability based on the present value of lease payments as adjusted, and adjusts the carrying value of the right-of-use assets accordingly. If the carrying value of the right-of-use asset is reduced to zero, but the lease liability needs to be further reduced, the balance is recognized in profit or loss. (2) Accounting treatment of leases under which the Company is lessor 2. The Company as the lessor: At the lease commencement date, the Company classifies a lease that transfers substantially all the risks and rewards incidental to ownership of an underlying asset to the lessee as a finance lease, and all other leases as operating leases. (1) Operating lease Lease receipts are recognized as lease income using the straight-line method over the lease term. Initial direct costs incurred are capitalized, amortized on the same basis as the recognition of lease income, and recognized in profit or loss by installments. Variable lease payments related to the operating lease which are not included in the lease receipts are recognized in profit or loss in the period during which they are incurred. (2) Finance lease At the lease commencement date, the Company recognizes the finance lease payments receivable based on the net investment in the lease (equal to the sum of unguaranteed residual value and the present value of lease receipts that are not received at the lease commencement date and discounted using the Company’s incremental interest rate), and derecognizes the assets held under the finance lease. The Company calculates and recognizes interest income using the interest rate implicit in the lease over the lease term. Variable lease payments that are not included in the measurement of the net investment in a lease are recognized in profit or loss when they are incurred. 3. Sale and leaseback (1) The Company as lessee In accordance with CASBE 14 - Revenue, the Company assesses and determines whether the transfer of any asset in a sale and leaseback transaction should be accounted for as a sale of that asset. 105 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 If the transfer of an asset is accounted for as a sale of the asset, the Company measures the right-of-use asset arising from the leaseback at the proportion of the original carrying value of the asset that relates to the right of use retained by the Company. Accordingly, the Company recognizes only the amount of any gain or loss that relates to the rights transferred to the lessor. Otherwise, the Company continues the recognition of the transferred asset, and recognizes a financial liability equal to the amount of transfer proceeds in accordance with CASBE 22 - Financial Instruments: Recognition and Measurement at the same time. (2) The Company as lessor In accordance with CASBE 14 - Revenue, the Company assesses and determines whether the transfer of any asset in a sale and leaseback transaction should be accounted for as a sale of that asset. If the transfer of an asset is accounted for as a sale of the asset, the Company accounts for the purchase of assets in accordance with other applicable standards, and accounts for the lease of assets in accordance with CASBE 21 - Leases. Otherwise, the Company does not recognize the transferred asset, and instead recognizes a financial asset equal to the amount of transfer proceeds in accordance with CASBE 22 - Financial Instruments: Recognition and Measurement. 42. Other Significant accounting policies and accounting estimates 1. Basis for the adoption of hedge accounting and its accounting treatment (1) Cash flow hedge. (2) A hedging relationship qualifies for hedge accounting if all of the following conditions are met: (i) the hedging relationship consists only of eligible hedging instruments and eligible hedged instruments; (ii) at the commencement of the hedge there is formal designation of hedging instruments and hedged item, and documentation of the hedging relationship and the Company’s risk management objective and strategy for undertaking the hedge; and (iii) the hedging relationship meets the hedging effectiveness requirements. The Company recognizes that the hedging relationship meets effectiveness requirements if all of the following conditions are met: (i) there is an economic relationship between the hedged item and the hedging instruments; (ii) the effect of credit risk does not dominate the value changes that result from the economic relationship between the hedged item and the hedging instruments; and (iii) the hedge ratio of the hedging relationship is the same as the ratio of the quantity of the hedged item that the Company actually hedges to the number of hedging instruments that 106 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 the Company actually uses to hedge such hedged item, but does not reflect an imbalance between the weightings of the hedged item and the hedging instrument. The Company assesses whether a hedging relationship meets the hedge effectiveness requirements at commencement and on an ongoing basis. If a hedging relationship ceases to meet the hedge effectiveness requirement relating to the hedge ratio but the risk management objective for that designated hedging relationship remains the same, the hedging relationship will be rebalanced. (3) Hedge accounting 1) Fair value hedge ① The gain or loss on a hedging instrument is recognized in profit or loss (or other comprehensive income, if the hedging instrument hedges a non-trading equity instrument (or a component thereof) at fair value through other comprehensive income). ② The gain or loss on a hedged item arising from risk exposure is recognized in profit or loss, with a corresponding adjustment to the book balance of the hedged item not measured at fair value. If the hedged item is a financial asset (or a component thereof) that is measured at fair value through other comprehensive income in accordance with Article XVIII of CASBE 22 “Financial Instruments: Recognition and Measurement”, the gain or loss arising from the risk exposure on the hedged item is recognized in profit or loss, without adjusting its book balance which has already been measured at fair value; if the hedged item is a non-trading equity instrument (or a component thereof) for which the Company has elected to present changes at fair value through other comprehensive income, the gain or loss arising from the risk exposure on the hedged item is recognized in profit or loss, without adjusting its book balance which has already been measured at fair value. When a hedged item is an unrecognized firm commitment (or a component thereof), the cumulative change in fair value of the hedged item subsequent to its designation is recognized as an asset or a liability with a corresponding gain or loss recognized in profit or loss. When a firm commitment is performed to acquire an asset or assume a liability, the initial book balance of the asset or the liability is adjusted to include the cumulative change in fair value of the hedged item that was previously recognized. For a hedged item that is a financial instrument (or a component thereof) measured at amortized cost, any adjustment on the book balance of the hedged item is amortized to profit or loss based on a recalculated effective interest rate at the date that amortization begins. For a financial asset (or a component thereof) that is a hedged item and measured at fair value through other comprehensive income in accordance with Article XVIII of CASBE 22 “Financial 107 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 Instruments: Recognition and Measurement”, the cumulative gain or loss previously recognized thereon is amortized in the same manner, and recognized in profit or loss, without adjusting its book balance. 2) Cash flow hedges ① The portion of the gain or loss on a hedging instrument that is determined to be an effective hedge is recognized in other comprehensive income as cash flow hedge reserve, while the ineffective portion is recognized in profit or loss. The cash flow hedge reserve is recognized at the lower of the following (in absolute amount): (i) the cumulative gain or loss on the hedging instrument from the commencement of the hedge; and (ii) the cumulative change in the present value of the estimated future cash flows of the hedged item from the commencement of the hedge. ② If a hedged forecast transaction subsequently results in the recognition of a non-financial asset or non-financial liability, or a hedged forecast transaction for a non-financial asset or non-financial liability becomes a firm commitment for which fair value hedge accounting is applied, the Company transfers out the amount of cash flow hedge reserve previously recognized in other comprehensive income and includes it in the initial cost of the asset or the liability. ③ For other cash flow hedges, the amount of cash flow hedge reserve previously recognized in other comprehensive income is transferred to profit or loss in the same period the hedged forecast sale affects profit or loss. 3) Hedges of a net investment in a foreign operation The portion of the gain or loss on a hedging instrument that is determined to be an effective hedge is recognized in other comprehensive income and reclassified from other comprehensive income into profit or loss on the disposal of the foreign operation, while the ineffective portion is recognized in profit or loss. 2. Accounting treatment related to share repurchase When the Company repurchases its shares for the purpose of reducing its registered capital, rewarding its employees or otherwise, if the purchased shares are to be held as treasury shares, the treasury shares are recorded at the amount actually paid and the relevant filing procedures are performed; if the repurchased shares are to be retired, the difference between the total book value of the shares retired and the amount actually paid therefore is recognized as a reduction in capital reserve, and if the capital reserve is not sufficient to absorb the difference, the remaining balance is charged against the retained earnings. If the repurchased shares are granted to the employees as equity- settled share-based payments, the purchase price paid by the employees upon exercise of their rights is recognized as a reduction in the cost of the relevant treasury shares vested in the employees and capital reserve (other capital reserve) accumulated within the vesting period, with a corresponding adjustment to capital reserve (share premium). 108 Suzhou Dongshan Precision Manufacturing Co., Ltd.

Risks Associated with Financial Instruments 1. Risks arising from financial instruments The Company’s objectives of risk management are to maintain a balance between risk and income, minimize the negative effect of risks on the operating results of the Company and maximize the interests of the shareholders and other equity investors. On the basis of such objectives of risk management, the Company’s basic risk management policy is designed to identify and analyze all kinds of risks facing the Company, set appropriate risk thresholds in risk management, and monitor risks and adherence to limits in a timely and reliable manner. The Company faces a variety of risks associated with financial instruments in its daily activities, mainly including credit risk, liquidity risk and market risk. Below is a summary of the policies for managing such risks considered and approved by the management. (I) Credit risk Credit risk is the risk that one party to a financial instrument will cause a financial loss to the other party by failing to discharge an obligation. 1. Credit risk management practice (1) Assessment of credit risk At each balance sheet date, the Company assesses whether the credit risk of a financial instrument has increased significantly since initial recognition. In assessing whether the credit risk has increased significantly since initial recognition, the Company takes into account reasonable and supportable information, which is available without undue cost or effort, including qualitative and quantitative 158 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 analysis based on historical data, external credit risk rating, and forward-looking information. The Company determines the changes in default risk of financial instruments during their estimated lifetime through a comparison of the default risk at the balance sheet date and the initial recognition date, on an individual or collective basis. The Company determines that the credit risk of a financial instrument has increased significantly when one or more of the following qualitative and quantitative standards are met: 1) Quantitative standard, mainly relates to the scenario in which, at the balance sheet date, the probability of default in the remaining lifetime has risen by more than a certain percentage compared with the initial recognition; and/or 2) Qualitative standard mainly relates to significant adverse changes in the debtor’s business situation or financial position, and present or expected changes in technology, market, economy or legal environment that will have a material adverse effect on the debtor’s ability to repay. (2) Definition of default and credit-impaired assets A financial instrument is in default or credit impaired when one or more of the following conditions are met: 1) significant financial difficulty of the debtor. 2) any breach by the debtor of contract terms binding on it. 3) it becomes probable that the debtor will enter bankruptcy or other financial reorganization. 4) the creditors of the debtor, for economic or contractual reasons relating to the debtor’s financial difficulty, having granted to the debtor a concession that the creditors would not otherwise consider. 2. Measurement of expected credit losses The key factors in the measurement of expected credit losses include the probability of default, loss given default, and exposure to default risk. The Company has developed a model of the probability of default, loss given default and exposure to default risk on the basis of quantitative analysis of historical data (e.g. counterparty rating, guarantee measures and collateral type, payment method, etc.) and forward-looking information. 3. See Notes V(I)3, V(I)4, V(I)7 and V(I)10 for the conciliation table of opening balances and closing balances of allowance for impairment loss on financial instruments. 4. Credit risk exposure and credit risk concentration The Company’s credit risk is primarily attributable to cash and bank balances and receivables. In order to control such risks, the Company has taken the following measures: (1) Cash and bank balances The Company deposits its bank balances and other monetary capital in financial institutions with relatively high credit ratings, so its credit risk is relatively low. 159 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 (2) Accounts receivable The Company performs credit assessments on customers using credit settlement on an ongoing basis. The Company selects approved and creditworthy customers based on the result of credit assessment, and monitors the balance of accounts receivable from them on an ongoing basis, to avoid significant risk of doubtful accounts. As the Company only deals with approved and creditworthy third parties, no collateral is required. As of June 30, 2024, the Company faced certain credit concentration risks. In particular, 49.75% (December 31, 2023: 60.39%) of the Company’s accounts receivable came from the top 5 customers, without any collateral or other credit enhancement. The Company’s maximum exposure to credit risk is the carrying value of each financial asset in the balance sheet. (II) Liquidity risk Liquidity risk is the risk that the Company may not have enough cash to satisfy its obligation to deliver cash or other financial assets, due to the inability to liquidate financial assets at fair value in a timely manner, or failure of counterparties to discharge their contract liabilities, acceleration of debts, failure to generate expected cash flows, or otherwise. In order to control such risk, the Company utilizes a variety of financing tools such as settlement by means of notes, bank loans, etc., combines long-term and short-term financing to optimize financing structure, and maintains a balance between financing sustainability and flexibility. The Company has obtained lines of credit from many commercial banks to satisfy its working capital requirements and capital expenditures.

Market risk mainly includes interest risk and foreign exchange risk. 1. Interest risk Interest risk is the risk of fluctuation in the fair value or future cash flows of financial instruments due to changes in market interest rates. Interest-bearing financial instruments with fixed interest rates expose the Company to fair value interest rate risk, while interest- bearing financial instruments with floating interest rates expose the Company to cash flow interest rate risk. The Company determines the proportion of fixed-rate financial instruments and floating-rate financial instruments based on the market environment, and reviews and monitors the appropriateness of its portfolio of financial instruments on a regular basis. The cash flow interest rate risk that the Company faces is primarily associated with the floating-rate bank loans owed by the Company, which amounted to RMB2,447,213,171.46 as of June 30, 2024 (December 31, 2023: RMB1,406,781,793.94). Supposing the interest rate changes by 50 basic points while other variables remain unchanged, the Company’s total profit and shareholders’ interest will not be materially affected. 2. Foreign exchange risk Foreign exchange risk is the risk of fluctuation in the fair value or future cash flows of financial instruments due to changes in exchange rates. The Company’s foreign exchange risk relates mainly to foreign currency denominated monetary assets and liabilities. When a 161 Suzhou Dongshan Precision Manufacturing Co., Ltd. Semi-Annual Report 2024 short-term imbalance occurs on foreign currency denominated assets and liabilities, the Company may trade foreign currencies at market exchange rates when necessary, in order to maintain the net risk exposure at an acceptable level. See Note V(V)2 to the Financial Statements for details of foreign currency denominated monetary assets and liabilities as of the end of the reporting period. 2. Hedging 3. Financial assets XIII.
