INDEPENDENT AUDITORS’ REPORT

To the Board of Directors and Shareholders of ADVANTECH CO., LTD.

Opinion

We have audited the accompanying parent company only balance sheets of ADVANTECH CO., LTD. as at December 31, 2025 and 2024, and the related parent company only statements of comprehensive income, of changes in equity and of cash flows for the years then ended, and notes to the parent company only financial statements, including a summary of material accounting policies.

In our opinion, the accompanying parent company only financial statements present fairly, in all material respects, the financial position of ADVANTECH CO., LTD. as at December 31, 2025 and 2024, and its financial performance and its cash flows for the years then ended in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers.

Basis for opinion

We conducted our audits in accordance with the Regulations Governing Financial Statement Audit and Attestation Engagements of Certified Public Accountants and Standards on Auditing of the Republic of China. Our responsibilities under those standards are further described in the Auditors’ responsibilities for the audit of the parent company only financial statements section of our report. We are independent of ADVANTECH CO., LTD. in accordance with the Norm of Professional Ethics for Certified Public Accountant of the Republic of China, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of ADVANTECH CO., LTD.’s 2025 financial statements. These matters were addressed in the context of our audit of the parent company only financial statements as a whole and, in forming our opinion thereon, we do not provide a separate opinion on these matters.

Key audit matter for ADVANTECH CO., LTD.’s 2025 financial statements is stated as follows:

Recognition of sales revenue from the Intelligent Systems, Intelligent Service, and Advantech Service Plus and Others Business Group

Description

Refer to Note 4(30) for the related accounting policies on sales revenue and Note 6(18) for the details of revenues.

Due to global economic fluctuations in 2025, there was a significant fluctuation in the Company’s revenue from the Intelligent Systems, Intelligent Service, and Advantech Service Plus and Others Business Group. Therefore, we considered the recognition of sales revenue from the Intelligent Systems, Intelligent Service, and Advantech Service Plus and Others Business Group as the key audit matter.

How our audit addressed the matter

Our audit procedures performed in ADVANTECH CO., LTD. and its subsidiaries (recognised as investments accounted for under equity method) for the above key audit matter are as follows:

1. Obtained an understanding of and assessed the internal controls in relation to sales revenue, and validated its operating effectiveness.

2. Obtained the details of sales revenue from the Intelligent Systems, Intelligent Service, and Advantech Service Plus and Others Business Group for the entire year, and selected samples of sales revenue transactions and related documents to confirm the appropriateness of revenue recognition.

3. Inspected significant abnormal sales returns and allowances after the balance sheet date.

4. Performed accounts receivable confirmation procedure to significant customers.

~3~

Responsibilities of management and those charged with governance for the parent company only financial statements

Management is responsible for the preparation and fair presentation of the parent company only financial statements in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and for such internal control as management determines is necessary to enable the preparation of parent company only financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the parent company only financial statements, management is responsible for assessing the ability of ADVANTECH CO., LTD. to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate ADVANTECH CO., LTD. or to cease operations, or has no realistic alternative but to do so.

Those charged with governance, including the audit committee, are responsible for overseeing the financial reporting process of ADVANTECH CO., LTD.

Independent auditors’ responsibilities for the audit of the parent company only financial statements

Our objectives are to obtain reasonable assurance about whether the parent company only financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the Standards on Auditing of the Republic of China will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these parent company only financial statements.

~4~

As part of an audit in accordance with the Standards on Auditing of the Republic of China, we exercise professional judgment and professional skepticism throughout the audit. We also:

1. Identify and assess the risks of material misstatement of the parent company only financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

2. Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of internal control of ADVANTECH CO., LTD.

3. Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

4. Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the ability of ADVANTECH CO., LTD. to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditors’ report to the related disclosures in the parent company only financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditors’ report. However, future events or conditions may cause ADVANTECH CO., LTD. to cease to continue as a going concern.

5. Evaluate the overall presentation, structure and content of the parent company only financial statements, including the disclosures, and whether the parent company only financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

6. Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within ADVANTECH CO., LTD. to express an opinion on the parent company only financial statements. We are responsible for the direction, supervision and performance of the audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

~5~

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the parent company only financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditors’ report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

Specific provisions of Amendments to IFRS 9 and IFRS 7, 'Amendments to the classification and measurement of financial instruments’

• A. Clarify and add further guidance for assessing whether a financial asset meets the solely payments of principal and interest (SPPI) criterion, covering contractual terms that can change cash flows based on contingent events (for example, interest rates linked to ESG targets), non-recourse features and contractually-linked instruments.

• B. Add new disclosures for certain instruments with contractual terms that can change cash flows (such as some instruments with features linked to the achievement of environment, social and governance (ESG) targets), including a qualitative description of the nature of the contingent event, quantitative information about the possible changes to contractual cash flows that could result from those contractual terms and the gross carrying amount of financial assets and amortised cost of financial liabilities subject to these contractual terms.

• C. Clarify the date of recognition and derecognition of some financial assets and liabilities, with a new exception relating to the derecognition of a financial liability (or part of a financial liability) settled through an electronic cash transfer system. Applying the exception, an entity is permitted to derecognise a financial liability at an earlier date if, and only if, the entity has initiated a payment instruction and specific conditions are met.

~15~

The conditions for the exception are that the entity making the payment does not have:

• (a) the practical ability to withdraw, stop or cancel the payment instruction;

• (b) the practical ability to access the cash used for settlement; and

• (c) significant settlement risk.

• D. Update the disclosures for equity instruments designated at fair value through other comprehensive income (FVOCI). The entity shall disclose the fair value of each class of investment and is no longer required to disclose the fair value of each investment. In addition, the amendments require the entity to disclose the fair value gain or loss presented in other comprehensive income during the period, showing separately the fair value gain or loss related to investments derecognised during the reporting period and the fair value gain or loss related to investments held at the end of the reporting period; and any transfers of the cumulative gain or loss within equity during the reporting period related to the investments derecognised during that reporting period.

4. SUMMARY OF MATERIAL ACCOUNTING POLICIES

The principal accounting policies applied in the preparation of these parent company only financial statements are set out below. These policies have been consistently applied to all the periods presented, unless otherwise stated.

(1) Compliance statement

These parent company only financial statements have been prepared in accordance with the “Regulations Governing the Preparation of Financial Reports by Securities Issuers”.

(2) Basis of preparation

• A. Except for the following items, the parent company only financial statements have been prepared under the historical cost convention:

• (a) Financial assets and liabilities (including derivative instruments) at fair value through profit or loss.

• (b) Financial assets at fair value through other comprehensive income.

• (c) Defined benefit liabilities recognised based on the net amount of pension fund assets less present value of defined benefit obligation.

• B. The preparation of parent company only financial statements requires the use of certain critical accounting estimates. It also requires management to exercise its judgement in the process of applying the Company’s accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the parent company only financial statements are disclosed in Note 5.

(3) Foreign currency translation

Items included in the parent company only financial statements are measured using the currency of the primary economic environment in which the entity operates (the “functional currency”). The parent company only financial statements are presented in “New Taiwan Dollars (NTD)”, which is the Company’s functional and presentation currency.

• A. Foreign currency transactions and balances

• (a) Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions or valuation where items are remeasured. Foreign exchange gains and losses resulting from the settlement of such transactions are recognised in profit or loss in the period in which they arise.

• (b) Monetary assets and liabilities denominated in foreign currencies at the period end are retranslated at the exchange rates prevailing at the balance sheet date. Exchange differences arising upon re-translation at the balance sheet date are recognised in profit or loss.

• (c) Non-monetary assets and liabilities denominated in foreign currencies held at fair value through profit or loss are re-translated at the exchange rates prevailing at the balance sheet date; their translation differences are recognised in profit or loss. Non-monetary assets and liabilities denominated in foreign currencies held at fair value through other comprehensive

~17~

income are re-translated at the exchange rates prevailing at the balance sheet date; their translation differences are recognised in other comprehensive income. However, nonmonetary assets and liabilities denominated in foreign currencies that are not measured at fair value are translated using the historical exchange rates at the dates of the initial transactions.

• (d) All foreign exchange gains and losses are presented in the statement of comprehensive income within ‘other gains and losses’.

• B. Translation of foreign operations

• (a) The operating results and financial position of all the subsidiaries, associates and joint arrangments that have a functional currency different from the presentation currency are translated into the presentation currency as follows:

  • i. Assets and liabilities for each balance sheet presented are translated at the closing exchange rate at the date of that balance sheet;

  • ii. Income and expenses for each statement of comprehensive income are translated at average exchange rates of that period; and

  • iii. All resulting exchange differences are recognised in other comprehensive income.

• (b) When the foreign operation partially disposed of or sold is an associate or joint arrangement, exchange differences that were recorded in other comprehensive income are proportionately reclassified to profit or loss as part of the gain or loss on sale. In addition, even when the Company retains partial interest in the former foreign associate or joint arrangement after losing significant influence over the former foreign associate, or losing joint control of the former joint arrangement, such transactions should be accounted for as disposal of all interest in these foreign operations.

• (c) When the foreign operation partially disposed of or sold is a subsidiary, cumulative exchange differences that were recorded in other comprehensive income are proportionately transferred to the non-controlling interest in this foreign operation. In addition, even when the Company retains partial interest in the former foreign subsidiary after losing control of the former foreign subsidiary, such transactions should be accounted for as disposal of all interest in the foreign operation.

(4) Classification of current and non-current items

• A. Assets that meet one of the following criteria are classified as current assets; otherwise they are classified as non-current assets:

• (a) Assets that are expected to be realised, or are intended to be sold or consumed in the normal operating cycle;

• (b) Assets that are held primarily for the purpose of trading;

• (c) Assets that are expected to be realised within twelve months after the reporting period;

• (d) Cash and cash equivalents, excluding restricted cash and cash equivalents and those that are to be exchanged or used to settle liabilities for at least twelve months after the reporting period.

~18~

• B. Liabilities that meet one of the following criteria are classified as current liabilities; otherwise they are classified as non-current liabilities:

  • (a) Liabilities that are expected to be settled in the normal operating cycle;

  • (b) Liabilities that are held primarily for the purpose of trading ;

  • (c) Liabilities that are due to be settled within twelve months after the reporting period;

  • (d) It does not have the right at the end of the reporting period to defer settlement of the liability at least twelve months after the reporting period.

• (5) Cash equivalents

Cash equivalents refer to short-term, highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of changes in value. Time deposits that meet the definition above and are held for the purpose of meeting short-term cash commitments in operations are classified as cash equivalents.

(6) Financial assets at fair value through profit or loss

• A. Financial assets at fair value through profit or loss are financial assets that are not measured at amortised cost or fair value through other comprehensive income.

• B. On a regular way purchase or sale basis, financial assets at fair value through profit or loss are recognised and derecognised using trade date accounting.

• C. At initial recognition, the Company measures the financial assets at fair value and recognises the transaction costs in profit or loss. The Company subsequently measures the financial assets at fair value, and recognises the gain or loss in profit or loss.

• D. The Company recognises the dividend income when the right to receive payment is established, future economic benefits associated with the dividend will flow to the Company and the amount of the dividend can be measured reliably.

• (7) Financial assets at fair value through other comprehensive income

• A. Financial assets at fair value through other comprehensive income comprise equity securities which are not held for trading, and for which the Company has made an irrevocable election at initial recognition to recognise changes in fair value in other comprehensive income.

• B. On a regular way purchase or sale basis, financial assets at fair value through other comprehensive income are recognised and derecognised using trade date accounting.

• C. At initial recognition, the Company measures the financial assets at fair value plus transaction costs. The Company subsequently measures the financial assets at fair value. The changes in fair value of equity investments that were recognised in other comprehensive income are reclassified to retained earnings and are not reclassified to profit or loss following the derecognition of the investment. Dividends are recognised as revenue when the right to receive payment is established, future economic benefits associated with the dividend will flow to the Company and the amount of the dividend can be measured reliably.

~19~

(8) Financial assets at amortised cost

• A. Financial assets at amortised cost are those that meet all of the following criteria:

  • (a) The objective of the Company’s business model is achieved by collecting contractual cash flows.

  • (b) The assets’ contractual cash flows represent solely payments of principal and interest.

• B. On a regular way purchase or sale basis, financial assets at amortised cost are recognised and derecognised using trade date accounting.

• C. At initial recognition, the Company measures the financial assets at fair value plus transaction costs. Interest income from these financial assets is included in finance income using the effective interest method. A gain or loss is recognised in profit or loss when the asset is derecognised or impaired.

• D. The Company's time deposits which do not fall under cash equivalents are those with a short maturity period and are measured at initial investment amount as the effect of discounting is immaterial.

• (9) Accounts and notes receivable

• A. Accounts and notes receivable entitle the Company a legal right to receive consideration in exchange for transferred goods or rendered services.

• B. The short-term accounts and notes receivable without bearing interest are subsequently measured at initial invoice amount as the effect of discounting is immaterial.

(10) Impairment of financial assets

• For financial assets at amortised cost including accounts and notes receivable that have a significant financing component, at each reporting date, the Company recognises the impairment provision for 12 months expected credit losses if there has not been a significant increase in credit risk since initial recognition or recognises the impairment provision for the lifetime expected credit losses (ECLs) if such credit risk has increased since initial recognition after taking into consideration all reasonable and verifiable information that includes forecasts. On the other hand, for accounts and notes recivable that do not contain a significant financing component, the Company recognises the impairment provision for lifetime ECLs.

(11) Derecognition of financial assets

The Company decognises a financial asset when one of the following conditions is met:

• A. The contractual rights to receive the cash flows from the financial asset expire.

• B. The contractual rights to receive cash flows of the financial asset have been transferred and the Company has transferred substantially all risks and rewards of ownership of the financial asset.

• C. The contractual rights to receive cash flows of the financial asset have been transferred; however, the Company has not retained control of the financial asset.

~20~

- (12) Leasing arrangements (lessor) operating leases

Lease income from an operating lease (net of any incentives given to the lessee) is recognised in profit or loss on a straight-line basis over the lease term.

(13) Inventories

Inventories are stated at the lower of cost and net realizable value. Cost is determined using the weighted-average method. The cost of finished goods and work in progress comprises raw materials, direct labour, other direct costs and related production overheads. It excludes borrowing costs. The item by item approach is used in applying the lower of cost and net realisable value. Net realisable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and the estimated costs necessary to make the sale.

(14) Investments accounted for using equity method

• A. Subsidiaries are all entities controlled by the Company. The Company controls an entity when the Company is exposed, or has rights, to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity.

• B. Unrealised profit (loss) arising from the transactions between the Company and subsidiaries have been offset. Accounting policies of subsidiaries have been adjusted where necessary to ensure consistency with the policies adopted by the Company.

• C. The Company’s share of its subsidiaries’ post-acquisition profits or losses is recognized in profit or loss, and its share of post-acquisition movements in other comprehensive income is recognised in other comprehensive income. When the Company’s share of losses in a subsidiary equals or exceeds its interest in the subsidiary, the Company continues to recognise losses proportionate to its ownership.

• D. Changes in a parent’s ownership interest in a subsidiary that do not result in the parent losing control of the subsidiary (transaction with non-controlling interests) are accounted for as equity transactions, i.e. transactions with owners in their capacity as owners. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognised directly in equity.

• E. Associates are all entities over which the Company has significant influence but not control. In general, it is presumed that the investor has significant influence, if an investor holds, directly or indirectly 20% or more of the voting power of the investee. Investments in associates are accounted for using the equity method and are initially recognised at cost.

• F. The Company’s share of its associates’ post-acquisition profits or losses is recognised in profit or loss, and its share of post-acquisition movements in other comprehensive income is recognised in other comprehensive income. When the Company’s share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Company does not recognise further losses, unless it has incurred legal or constructive obligations or made payments on behalf of the associate.

~21~

• G. When changes in an associate’s equity do not arise from profit or loss or other comprehensive income of the associate and such changes do not affect the Company’s ownership percentage of the associate, the Company recognises change in ownership interests in the associate in ‘capital surplus’ in proportion to its ownership.

• H. Unrealised gains on transactions between the Company and its associates are eliminated to the extent of the Company’s interest in the associates. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been adjusted where necessary to ensure consistency with the policies adopted by the Company.

• I. In the case that an associate issues new shares and the Company does not subscribe or acquire new shares proportionately, which results in a change in the Company’s ownership percentage of the associate but maintains significant influence on the associate, then ‘capital surplus’ and ‘investments accounted for under the equity method’ shall be adjusted for the increase or decrease of its share of equity interest. If the above condition causes a decrease in the Company’s ownership percentage of the associate, in addition to the above adjustment, the amounts previously recognised in other comprehensive income in relation to the associate are reclassified to profit or loss proportionately on the same basis as would be required if the relevant assets or liabilities were disposed of.

• J. Upon loss of significant influence over an associate, the Company remeasures any investment retained in the former associate at its fair value. Any difference between fair value and carrying amount is recognised in profit or loss.

• K. When the Company disposes its investment in an associate and loses significant influence over this associate, the amounts previously recognised in other comprehensive income in relation to the associate, are reclassified to profit or loss, on the same basis as would be required if the relevant assets or liabilities were disposed of. If it retains significant influence over this associate, the amounts previously recognised in other comprehensive income in relation to the associate are reclassified to profit or loss proportionately in accordance with the aforementioned approach.

• L. When the Company disposes its investment in an associate and loses significant influence over this associate, the amounts previously recognised as capital surplus in relation to the associate are transferred to profit or loss. If it retains significant influence over this associate, the amounts previously recognised as capital surplus in relation to the associate are transferred to profit or loss proportionately.

• M. At the balance sheet date, the Company performs an impairment test for an investment in an associate when there is an indication that the investment may be impaired. The entire carrying amount of the investment (including goodwill) is tested for impairment as a single asset, by comparing its recoverable amount (higher of value in use and fair value less costs of disposal) with its carrying amount. Any impairment loss recognised forms part of the carrying amount of the investment. Any reversal of impairment loss is recognised to the extent that the recoverable

~22~

amount of the investment subsequently increases.

• N. Pursuant to the Rules Governing the Preparation of Financial Statements by Securities Issuers, profit (loss) of the current period and other comprehensive income in the parent company only financial statements shall equal to the amount attributable to owners of the parent in the consolidated financial statements. Owners’ equity in the parent company only financial statements shall equal to equity attributable to owners of the parent in the consolidated financial statements.

(15) Property, plant and equipment

• A. Property, plant and equipment are initially recorded at cost.

• B. Subsequent costs are included in the asset’s carrying amount or recognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Company and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognised. All other repairs and maintenance are charged to profit or loss during the financial period in which they are incurred.

• C. Land is not depreciated. Other property, plant and equipment apply cost model and are depreciated using the straight-line method to allocate their cost over their estimated useful lives. Each part of an item of property, plant, and equipment with a cost that is significant in relation to the total cost of the item must be depreciated separately.

• D. The assets’ residual values, useful lives and depreciation methods are reviewed, and adjusted if appropriate, at each financial year-end. If expectations for the assets’ residual values and useful lives differ from previous estimates or the patterns of consumption of the assets’ future economic benefits embodied in the assets have changed significantly, any change is accounted for as a change in estimate under IAS 8, ‘Accounting Policies, Changes in Accounting Estimates and Errors’, from the date of the change. The estimated useful lives of property, plant and equipment are as follows:

Buildings Main buildings 36 ~ 51 years Electronic equipment 5 years Engineering systems 5 years Machinery and equipment 2 ~ 9 years Office equipment 2 ~ 6 years Other equipment 2 ~ 24 years

(16) Leasing arrangements (lessee) - right-of-use assets/lease liabilities

• A. Leases are recognised as a right-of-use asset and a corresponding lease liability at the date at which the leased asset is available for use by the Company. For short-term leases or leases of low-value assets, lease payments are recognised as an expense on a straight-line basis over the lease term.

~23~

• B. Lease liabilities include the net present value of the remaining lease payments at the commencement date, discounted using the incremental borrowing interest rate. Lease payments are comprised of fixed payments, less any lease incentives receivable. The Company subsequently measures the lease liability at amortised cost using the interest method and recognises interest expense over the lease term. The lease liability is remeasured and the amount of remeasurement is recognised as an adjustment to the right-of-use asset when there are changes in the lease term or lease payments and such changes do not arise from contract modifications.

• C. At the commencement date, the right-of-use asset is stated at cost comprising the following: (a) The amount of the initial measurement of lease liability;

• (b) Any lease payments made at or before the commencement date;

• (c) Any initial direct costs incurred by the lessee; and

• (d) An estimate of 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 right-of-use asset is measured subsequently using the cost model and is depreciated from the commencement date to the earlier of the end of the asset’s useful life or the end of the lease term. When the lease liability is remeasured, the amount of remeasurement is recognised as an adjustment to the right-of-use asset.

• D. For lease modifications that decrease the scope of the lease, the lessee shall decrease the carrying amount of the right-of-use asset and remeasure the lease liability to reflect the partial or full termination of the lease, and recognise the difference in profit or loss. For all other lease modifications, the lessee shall remeasure the lease liability and adjust the right-of-use asset, correspondingly.

(17) Intangible assets

• A. Goodwill

• Goodwill arises in a business combination accounted for by applying the acquisition method.

• B. Intangible assets, except for goodwill, are mainly software and technology licencing, and are amortised on a straight-line basis over their estimated useful lives of 1 ~ 8 years.

(18) Impairment of non-financial assets

• A. The Company assesses at each balance sheet date the recoverable amounts of those assets where there is an indication that they are impaired. An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell or value in use. Except for goodwill, when the circumstances or reasons for recognising impairment loss for an asset in prior years no longer exist or diminish, the impairment loss is reversed. The increased carrying amount due to reversal should not be more than what the depreciated or amortised historical cost would have been if the impairment had not been recognised.

~24~

• B. The recoverable amounts of goodwill shall be evaluated periodically. An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount. Impairment loss of goodwill previously recognised in profit or loss shall not be reversed in the following years.

• C. For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the cash-generating units, or groups of cash-generating units, that is/are expected to benefit from the synergies of the business combination. Each unit or group of units to which the goodwill is allocated represents the lowest level within the entity at which the goodwill is monitored for internal management purposes. Goodwill is monitored at the operating segment level.

(19) Notes and accounts payable

• A. Accounts payable are liabilities for purchases of raw materials, goods or services and notes payable are those resulting from operating and non-operating activities.

• B. The short-term notes and accounts payable without bearing interest are subsequently measured at initial invoice amount as the effect of discounting is immaterial.

(20) Financial liabilities at fair value through profit or loss

• A. Financial liabilities are classified in this category of held for trading if acquired principally for the purpose of repurchasing in the short-term. Derivatives are also categorised as financial liabilities held for trading unless they are designated as hedges.

• B. At initial recognition, the Company measures the financial liabilities at fair value. All related transaction costs are recognised in profit or loss. The Company subsequently measures these financial liabilities at fair value with any gain or loss recognised in profit or loss.

(21) Derecognition of financial liabilities

A financial liability is derecognised when the obligation specified in the contract is either discharged or cancelled or expires.

(22) Offsetting financial instruments

Financial assets and liabilities are offset and reported in the net amount in the balance sheet when there is a legally enforceable right to offset the recognised amounts and there is an intention to settle on a net basis or realise the asset and settle the liability simultaneously.

(23) Non-hedging derivatives

Non-hedging derivatives are initially recognised at fair value on the date a derivative contract is entered into and recorded as financial assets or financial liabilities at fair value through profit or loss. They are subsequently remeasured at fair value and the gains or losses are recognised in profit or loss.

~25~

(24) Provisions

• Provisions are recognised when the Company has a present legal or constructive obligation as a result of past events, and it is probable that an outflow of economic resources will be required to settle the obligation and the amount of the obligation can be reliably estimated. Provisions are measured at the present value of the expenditures expected to be required to settle the obligation on the balance sheet date, which is discounted using a pre-tax discount rate that reflects the current market assessments of the time value of money and the risks specific to the obligation. When discounting is used, the increase in the provision due to passage of time is recognised as interest expense. Provisions are not recognised for future operating losses.

(25) Employee benefits

• A. Short-term employee benefits

Short-term employee benefits are measured at the undiscounted amount of the benefits expected to be paid in respect of service rendered by employees in a period and should be recognised as expense in that period when the employees render service.

• B. Pensions

• (a) Defined contribution plans

For defined contribution plans, the contributions are recognised as pension expense when they are due on an accrual basis. Prepaid contributions are recognised as an asset to the extent of a cash refund or a reduction in the future payments.

• (b) Defined benefit plans

  • i. Net obligation under a defined benefit plan is defined as the present value of an amount of pension benefits that employees will receive on retirement for their services with the Company in current period or prior periods. The liability recognised in the balance sheet in respect of defined benefit pension plans is the present value of the defined benefit obligation at the balance sheet date less the fair value of plan assets. The net defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method. The rate used to discount is determined by using interest rates of government bonds (at the balance sheet date) of a currency and term consistent with the currency and term of the employment benefit obligations.

  • ii. Remeasurements arising on defined benefit plans are recognised in other comprehensive income in the period in which they arise and are recorded as retained earnings.

  • iii. Past service costs are recognised immediately in profit or loss.

• C. Termination benefits

• Termination benefits are employee benefits provided in exchange for the termination of employment as a result from either the Company’s decision to terminate an employee’s employment before the normal retirement date, or an employee’s decision to accept an offer of redundancy benefits in exchange for the termination of employment. The Company recognises

~26~

expense as it can no longer withdraw an offer of termination benefits or it recognises relating restructuring costs, whichever is earlier. Benefits that are expected to be due more than 12 months after balance sheet date shall be discounted to their present value.

• D. Employees’ compensation and directors’ remuneration

• Employees’ compensation and directors’ remuneration are recognised as expense and liability, provided that such recognition is required under legal or constructive obligation and those amounts can be reliably estimated. Any difference between the resolved amounts and the subsequently actual distributed amounts is accounted for as changes in estimates.

- (26) Employee share based payment

• A. For the equity-settled share-based payment arrangements, the employee services received are measured at the fair value of the equity instruments granted at the grant date, and are recognised as compensation cost over the vesting period, with a corresponding adjustment to equity. The fair value of the equity instruments granted shall reflect the impact of market vesting conditions and non-vesting conditions. Compensation cost is subject to adjustment based on the service conditions that are expected to be satisfied and the estimates of the number of equity instruments that are expected to vest under the non-market vesting conditions at each balance sheet date. Ultimately, the amount of compensation cost recognised is based on the number of equity instruments that eventually vest.

• B. The share-based payment grant date is the date that the Company and employees reached a consensus on the terms and provisions of share-based payment arrangements.

(27) Income tax

• A. The tax expense for the period comprises current and deferred tax. Tax is recognised in profit or loss, except to the extent that it relates to items recognised in other comprehensive income or items recognised directly in equity, in which cases the tax is recognised in other comprehensive income or equity.

• B. The current income tax expense is calculated on the basis of the tax laws enacted or substantively enacted at the balance sheet date in the countries where the Company operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in accordance with applicable tax regulations. It establishes provisions where appropriate based on the amounts expected to be paid to the tax authorities. An additional tax is levied on the unappropriated retained earnings and is recorded as income tax expense in the year the stockholders resolve to retain the earnings.

• C. Deferred income tax is recognised, using the balance sheet liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated balance sheet. However, the deferred tax is not accounted for if it arises from initial recognition of goodwill or of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or

~27~

loss. Deferred tax is provided on temporary differences arising on investments in subsidiaries and associates, except where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax is determined using tax rates (and laws) that have been enacted or substantially enacted by the balance sheet date and are expected to apply when the related deferred tax asset is realised or the deferred tax liability is settled.

• D. Deferred tax assets are recognised only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilised. At each balance sheet date, unrecognised and recognised deferred tax assets are reassessed.

(28) Share capital

Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or stock options are shown in equity as a deduction, net of tax, from the proceeds.

(29) Dividends

Dividends are recorded in the Company’s financial statements in the period in which they are resolved by the Company’s shareholders. Cash dividends are recorded as liabilities.

(30) Revenue recognition

• A. Sales of goods

• (a) The Company manufactures and sells embedded computing boards, industrial automation products, applied computers and industrial computers. Sales are recognised when control of the products has transferred, being when the products are delivered to the customer, the customer has full discretion over the channel and price to sell the products, and there is no unfulfilled obligation that could affect the customer’s acceptance of the products. Delivery occurs when the products have been shipped to the specific location, the risks of obsolescence and loss have been transferred to the customer, and either the customer has accepted the products in accordance with the sales contract, or the Company has objective evidence that all criteria for acceptance have been satisfied. When the material is removed for processing, the control of the ownership of the processed product is not transferred, so the income is not recognised when the material is removed.

• (b) The Company’s obligation to provide a repair for faulty products under the standard warranty terms is recognised as a provision.

• (c) A receivable is recognised when the goods are delivered as this is the point in time that the consideration is unconditional because only the passage of time is required before the payment is due.

• B. Revenue from rendering services

Revenue from rendering services comes from developing products and extended warranty services. Such revenue is recognised when services are provided.

~28~

(31) Government grants

Government grants are recognised at their fair value only when there is reasonable assurance that the Company will comply with any conditions attached to the grants and the grants will be received. Government grants are recognised in profit or loss on a systematic basis over the periods in which the Company recognises expenses for the related costs for which the grants are intended to compensate.

(32) Business combinations

• A. The Company uses the acquisition method to account for business combinations. The consideration transferred for an acquisition is measured as the fair value of the assets transferred, liabilities incurred or assumed and equity instruments issued at the acquisition date, plus the fair value of any assets and liabilities resulting from a contingent consideration arrangement. All acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. For each business combination, the Company measures at the acquisition date components of non-controlling interests in the acquiree that are present ownership interests and entitle their holders to the proportionate share of the entity’s net assets in the event of liquidation at either fair value or the present ownership instruments’ proportionate share in the recognised amounts of the acquiree’s identifiable net assets. All other non-controlling interests should be measured at the acquisition-date fair value.

• B. The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the fair value of any previous equity interest in the acquiree over the fair value of the identifiable assets acquired and the liabilities assumed is recorded as goodwill at the acquisition date. If the total of consideration transferred, non-controlling interest in the acquiree recognised and the fair value of previously held equity interest in the acquiree is less than the fair value of the identifiable assets acquired and the liabilities assumed, the difference is recognised directly in profit or loss on the acquisition date.

5. CRITICAL ACCOUNTING JUDGEMENTS, ESTIMATES AND KEY SOURCES OF ASSUMPTION UNCERTAINTY

The preparation of these parent company only financial statements requires management to make critical judgements in applying the Company’s accounting policies and make critical assumptions and estimates concerning future events. Assumptions and estimates may differ from the actual results and are continually evaluated and adjusted based on historical experience and other factors. Such assumptions and estimates have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year; and the related information is addressed below:

~29~

Critical accounting estimates and assumptions

Evaluation of inventories

As inventories are stated at the lower of cost and net realisable value, the Company must determine the net realisable value of inventories on balance sheet date using judgements and estimates. Due to the rapid technology innovation, the Company evaluates the amounts of normal inventory consumption, obsolete inventories or inventories without market selling value on balance sheet date, and writes down the cost of inventories to the net realisable value. Such an evaluation of inventories is principally based on the demand for the products within the specified period in the future. Therefore, there might be material changes to the evaluation.

As of December 31, 2025, the carrying amount of inventories was $5,425,416.

6. DETAILS OF SIGNIFICANT ACCOUNTS

(1) Cash and cash equivalents

• A. The Company transacts with a variety of financial institutions all with high credit quality to disperse credit risk, so it expects that the probability of counterparty default is remote.

• B. The Company has no cash and cash equivalents pledged to others.

• A. These investments in equity instruments are held for medium to long-term strategic purposes. Accordingly, the management elected to designate these investments in equity instruments as at fair value through other comprehensive income as they believe that recognizing short-term fluctuations in these investments’ fair value in profit or loss would not be consistent with the Company’s strategy of holding these investments for long-term purposes.

• B. Amounts recognised in profit or loss and other comprehensive income in relation to the financial assets at fair value through other comprehensive income are listed below:

		300,384 $

• (b) In 2024 and 2025, Axiomtek converted employee stock options into common shares, and converted corporate bonds into common shares, which resulted to a decrease in its equity interest to 25.96%.

~36~

• (c) In the first quarter of 2024 and the third quarter of 2025, Winmate converted employee stock options into common shares, and converted corporate bonds into common shares. Additionally, during the third to the fourth quarter in 2025, the Company disposed of part of its equity interest in Winmate, which resulted to a decrease in its equity interest to 14.58%. However, the Company continues to hold significant influence over Winmate as the Company remains as one of its directors.

• (d) In the second quarter of 2024, AIMobile made a capital reduction to offset the deficit and a capital increase. As the Company did not subscribe to the capital increase in proportion to its shareholding percentage, its equity interest decreased from 27.00% to 9.81%. As the Company lost significant influence over AIMobile, the investment in AIMobile accounted for under equity method was reclassified to financial assets at fair value through other comprehensive income - non-current.

• (e) In the second quarter of 2024, the Compnay lost control over Group LNC, but still has significant influence over them. Accordingly, the investments in Group LNC were reclassified to investments accounted for under equity method. In the fourth quarter of 2024, LNC made a cash capital increase. As the Company did not subscribe to the capital increase in proportion to its shareholding percentage, its equity interest decreased from 44.60% to 40.55%.

• C. The fair value of the Company’s associates which have quoted market price is as follows:

• December 31, 2025 December 31, 2024

• Fair value of associates $ 4,316,344 $ 5,580,575

• D. The Company is the single largest shareholder of Axiomtek and Winmate. Considering that the other shareholders hold more shares than the Company and the degree of other shareholders involvement in prior shareholders’ meeting and record of voting rights for major proposals, and the Company has no substantial ability to direct the relevant operating and financial activities, the Company has no control, but only has significant influence over the companies.

• E. The Company is the single largest shareholder of LNC. Considering that the other shareholders of the company collectively hold more shares than the Company and that the Company has only one of its directors, and the Company has no substantial ability to direct the relevant operating and financial activities, the Company has no control, but only has significant influence over the companies.

B. Impairment assessment of goodwill

(a) The impairment assessment of goodwill relies on the subjective judgment of the management, including identifying the cash-generating unit and determining its recoverable amount.

~40~

• (b) The Company assesses the recoverable amounts of goodwill for impairment at the end of the financial reporting period, and the recoverable amount is assessed based on the value-in-use.

• (c) The value-in-use calculations use cash flow projections based on financial budgets approved by the management. Management determined the budgeted gross margin and growth rate based on past performance and the expectations of market development. The market valuation used is consistent with the similar industries. The discount rates used reflect specific risks relating to the relevant operating segments and the time value of currency in real market.

(12) Pensions

• A. Defined benefit pension plan

• (a) The Company has a defined benefit pension plan in accordance with the Labor Standards Act, covering all regular employees’ service years prior to the enforcement of the Labor Pension Act on July 1, 2005 and service years thereafter of employees who chose to continue to be subject to the pension mechanism under the Labor Standards Act. Under the defined benefit pension plan, two units are accrued for each year of service for the first 15 years and one unit for each additional year thereafter, subject to a maximum of 45 units. Pension benefits are based on the number of units accrued and the average monthly salaries and wages of the last 6 months prior to retirement. The Company contributes monthly an amount equal to 2% of the employees’ monthly salaries and wages to the retirement fund deposited with Bank of Taiwan, the trustee, under the name of the independent retirement fund committee. Also, the Company would assess the balance in the aforementioned labor pension reserve account by December 31, every year. If the account balance is insufficient to pay the pension calculated by the aforementioned method to the employees expected to qualify for retirement in the following year, the Company will make contribution for the deficit by next March.

• (b) The amounts recognised in the balance sheets are as follows:

(d) The Bank of Taiwan was commissioned to manage the Fund of the Company’s defined benefit pension plan in accordance with the Fund’s annual investment and utilisation plan and the “Regulations for Revenues, Expenditures, Safeguard and Utilisation of the Labor

~42~

Retirement Fund” (Article 6: The scope of utilisation for the Fund includes deposit in domestic or foreign financial institutions, investment in domestic or foreign listed, over-thecounter, or private placement equity securities, investment in domestic or foreign real estate securitisation products, etc.). With regard to the utilisation of the Fund, its minimum earnings in the annual distributions on the final financial statements shall be no less than the earnings attainable from the amounts accrued from two-year time deposits with the interest rates offered by local banks. If the earnings is less than aforementioned rates, government shall make payment for the deficit after being authorised by the Regulator. The Company has no right to participate in managing and operating that fund and hence the Company is unable to disclose the classification of plan asset fair value in accordance with IAS 19 paragraph 142. The composition of fair value of plan assets as of December 31, 2025 and 2024 is given in the Annual Labor Retirement Fund Utilisation Report announced by the government.

(e) The principal actuarial assumptions used were as follows:

Discount rate Future salary increases rate	For the years ended December 31,	For the years ended December 31,
	2025 1.375% 4.00%	2024
		1.50%
		4.00%

Future mortality rate was estimated based on the 6[th] Taiwan Standard Ordinary Experience Mortality Table.

Because the main actuarial assumption changed, the present value of defined benefit obligation is affected. The analysis was as follows:

December 31, 2025 Effect on present value of defined benefit obligation December 31, 2024 Effect on present value of defined benefit obligation	Increase Decrease 0.25% 0.25% 8,150) ($ 8,413 $ 8,314) ($ 8,588 $ Discount rate	Future salaryincreasesrate	Future salaryincreasesrate
	Increase 0.25% 8,150) ($ 8,314) ($	Increase Decrease 0.25% 0.25% 8,066 $ 7,857) ($ 8,241 $ 8,022) ($	Decrease 0.25%

The sensitivity analysis above is based on one assumption which changed while the other conditions remain unchanged. In practice, more than one assumption may change all at once. The method of analysing sensitivity and the method of calculating net pension liability in the balance sheet are the same.

The methods and types of assumptions used in preparing the sensitivity analysis did not change compared to the previous period.

• (f) Expected contributions to the defined benefit pension plan of the Company for the year ending December 31, 2026 amount to $8,619.

~43~

The benefits accrued are paid monthly or in lump sum upon termination of employment.

  • (b) The pension costs under the defined contribution pension plan of the Company for the years ended December 31, 2025 and 2024 were $194,069 and $181,256, respectively.

• (13) Share-based payment

• A. Qualified employees of the Company were granted 8,000,000 options in 2023 and 7,500 options in 2020. Each option entitles the holder to subscribe for one and one thousand common shares of the Company, respectively. The holders of these shares include employees who meet certain criteria set by the Company from both domestic and overseas subsidiaries in which the Company directly or indirectly invests over 50%. Options issued in 2023 and 2020 are all valid for six years. All options are exercisable at certain percentages after the second anniversary year from the grant date. The exercise price of options granted in 2023 and 2020 was $200 (in dollars) per share. For any subsequent changes in the Company’s common shares, the exercise price and the number of options will be adjusted accordingly.

12. OTHERS

(1) Capital management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to provide returns for shareholders and to maintain an optimal capital structure to reduce the cost of capital. In order to maintain or adjust the capital structure, the Company may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt. The Company monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings (including ‘current and non-current borrowings’ as shown in the parent company only balance sheet) less cash and cash equivalents. Total capital is calculated as ‘equity’ as shown in the consolidated balance sheet.

During the year ended December 31, 2025, the Company’s strategy, which was unchanged from 2024, was to maintain the gearing ratio within reasonable range.

• Note 2: The balances included notes and accounts payable, accounts payable - related parties, other payables, other payables - related parties and guarantee deposits received, etc.

• B. Financial risk management policies

• (a) The Company’s major financial instruments included equity investments, accounts receivable, notes and accounts payable and lease liabilities. The Company’s Corporate treasury provides services to the business, coordinates access to domestic and international financial markets, monitors and manages the financial risks relating to the operations of the Company through internal risk reports which analyze exposures by degree and magnitude of risks. These risks include market risk (including foreign currency risk, interest rate risk and other price risk), credit risk, and liquidity risk.

• (b) The Company aims to minimize the effects of these risks by using derivative financial instruments to hedge risk exposures. The use of financial derivatives was governed by the Company’s policies approved by the Board of Directors, which provided written principles on foreign exchange risk, interest rate risk, credit risk, the use of financial derivatives and non-derivative financial instruments, and the investment of excess liquidity. Compliance with policies and exposure limits was reviewed by the internal auditors on a continuous basis. The Company did not enter into or trade financial instruments, including derivative financial instruments, for speculative purposes.

~65~

• (c) The Corporate Treasury reports quarterly to the Board of Directors on the Company’s current derivative instrument management.

• C. Significant financial risks and degrees of financial risks

• (a) Market risk

The Company is primarily exposed to financial risks due to changes in foreign currency exchange rates (refer to exchange rate risk section) and interest rates (refer to interest rate risk section) arising from its operating activities.

The Company entered into forward foreign exchange contracts to manage its foreign exchange risk.

There had been no change to the Company’s financial instruments exposure to market risks and the manner in which these risks were managed and measured.

Exchange rate risk

• i. The Company undertook operating activities and investments in foreign operations denominated in foreign currencies, which exposed the Company to foreign currency risk. The Company manages the risk that fluctuations in foreign currency could have on foreign currency denominated assets and future cash flow by entering into forward foreign exchange contracts, which allow the Company to mitigate but not fully eliminate the effect.

• ii. The maturities of the Company’s forward foreign exchange contracts were less than six months. These forward foreign exchange contracts did not meet the criteria for hedge accounting and were recognized in financial assets or liabilities at fair value through profit or loss. Refer to Note 6(2).

• iii. The Company’s significant financial assets and liabilities denominated in foreign currencies aggregated by the foreign currencies other than functional currencies and the related exchange rates between foreign currencies and respective functional currencies were as follows:

For the years ended December 31, 2025 and 2024, realised and unrealised net foreign exchange gains were $107,754 and $294,353, respectively. It is impractical to disclose net foreign exchange gains by each significant foreign currency due to the variety of the foreign currency transactions and functional currencies of the Company.

• iv. The Company is mainly exposed to the exchange rate fluctuation of USD, EUR and CNY.

• v. Analysis of foreign currency market risk arising from significant foreign exchange variation:

Interest rate risk

• i. The Company is exposed to interest rate risk because the Company maintains both floating and fixed interest rates of bank deposits. The Company does not operate hedging instruments for interest rates. The Company’s management monitors the market interest rates regularly. If it is needed, the management might perform necessary procedures for significant interest rate risks to control the risks from fluctuations in market interest rates.

• ii. The carrying amount of the Company’s financial assets and financial liabilities with exposure to interest rates at the balance sheet date were as follows:

• December 31, 2025 December 31, 2024

• Fair value interest rate risk - Financial assets $ 381,000 $ 387,986 - Financial liabilities 9,640 16,275 Cash flow interest rate risk - Financial assets 2,375,507 2,508,703

• iii. The sensitivity analyses below were determined based on the Company’s exposure to interest rates for non-derivative instruments at the balance sheet date. For floating rate liabilities, the analysis was prepared assuming the amount of the liability outstanding at the balance sheet date was outstanding for the whole reporting period. A 50-basis point increase or decrease was used when reporting interest rate risk internally to key management personnel and represents management’s assessment of the reasonably possible change in interest rates.

• iv. If interest rates had been 50 basis points higher and all other variables were held constant, the Company’s pre-tax profit for the years ended December 31, 2025 and 2024 would have increased by $11,878 and $12,544, respectively. Had interest rates been 50 basis points lower, the effects on the Company’s pre-tax profit would have been of the same amounts but negative. The source of the negative effects would have been mainly the floating-interest rates on bank deposits.

Other price risk

• i. The Company was exposed to equity price risk through its investments in listed and OTC equity securities. The Company manages this exposure by maintaining a portfolio of investments with different risks. The Company’s equity price risk was mainly concentrated on equity instruments trading in Taiwan.

• ii. If equity prices had been 1% higher, pre-tax other comprehensive income for the years ended December 31, 2025 and 2024 would have increased by $22,778 and $23,859, respectively, as a result of the changes in fair value of financial assets as at fair value through other comprehensive income. Had equity prices been 1% lower for the same year, the pre-tax other comprehensive income would have decreased by the same respective

~69~

amounts.

• iii. The Company’s sensitivity to equity prices increased or decreased because of volatility of stock price.

• (b) Credit risk

• i. Credit risk refers to the risk that the counterparty will default on its contractual obligations resulting in financial loss to the Company. As at balance sheet date, the Company’s maximum exposure to credit risk which will cause a financial loss to the Company due to failure of counterparties to discharge an obligation provided by the Company could arise from the carrying amount of the respective recognized financial assets, as stated in the balance sheets.

• ii. Accounts receivable consisted of a large number of customers, spread across diverse industries and geographical areas and, thus, no concentration of credit risk was observed. According to the Company’s credit policy, each department in the Company is responsible for managing and analysing the credit risk for each of their new clients before standard payment and delivery terms and conditions are offered. Internal risk control assesses the credit quality of the custromers, taking into account their financial position, past experience and other factors. Individual risks limits are set based on internal or external ratings. The utilization of credit limits is regularly monitored.

• iii. The average credit period of the sales of goods was 30-90 days. No interest was charged on accounts receivable. In order to minimize credit risk, the management of the Company has delegated a team responsible for determining credit limits, credit approvals and other monitoring procedures to ensure that follow-up action is taken to recover overdue debts. In addition, the Company reviews the recoverable amount of each individual trade debt at balance sheet date to ensure that adequate allowance is made for possible irrecoverable amounts. In this regard, the management believes the Company’s credit risk was significantly reduced.

• iv. The Company measures the loss allowance for accounts receivable at an amount that equals to lifetime expected credit losses. The expected credit losses on accounts receivable are estimated using a provision matrix prepared by reference to the past default experience of the customer, the customer’s current financial position, economic condition of the industry in which the customer operates, expected economic growth rate and industry trends at the same time. Based on the Company’s historical experience of credit loss, there is no significant loss difference between customer types, thus the provision matrix was not based on classification of customer types, but was based on the past due date to estimate expected credit losses.

• v. If there is evidence to prove that counterparties have a material financial difficulty and the recoverable amount cannot be estimated reliably, for example, the default occurs when counterparties are processing the liquidation or the debt has been past due over 1 year, the

~70~

Company will provide impairment loss in full. However, the Company will continue executing the recourse procedures to secure their rights, the recovered amount arising from the recourse procedures will be recognized in profit or loss.

• vi. The Company refers to the forecast ability of global economic indicators to adjust the loss rate which is based on historical and current information when assessing the future default possibility of notes and accounts receivable from general credit conditions customers. The provision matrix as of December 31, 2025 and 2024 is as follows:

Note: The Company wrote off accounts receivable and related loss allowance for the years ended December 31, 2025 and 2024 amounting to $2,091 and $499, respectively, as the customers’ accounts receivable have aged more than 2 years and the legal attest letters were served without receivables collected.

viii. For investments in debt instruments at amortised cost and fair value through profit or loss, the credit rating levels are presented below:

Financial assets at amortised cost Financial assets at fair value through profit or loss - Convertible corporate bonds - Corporate bonds Financial assets at fair value through profit or loss - Convertible corporate bonds - Corporate bonds	12 months 381,000 $ 184,500 $ 549,400 733,900 $ 12 months 194,597 $ 653,772 848,369 $	Significant increase in Impairment credit risk ofcredit - $ - $ - $ - $ - - - $ - $ Significant increase in Impairment credit risk of credit - $ - $ - - - $ - $ December31,2025 Lifetime December31,2024 Lifetime	Total

			184,500 $ 549,400 733,900 $ Total
			194,597 $ 653,772
			848,369 $

The financial assets at amortised cost held by the Company are ordinary corporate bonds issued by listed and OTC Companies. The financial assets at fair value through profit or loss held by the Company are convertible corporate bonds issued by listed and OTC companies and ordinary corporate bonds issued by public companies. The credit risk rating has no significant abnormal situation.

(c) Liquidity risk

• i. The Company manages liquidity risk by monitoring and maintaining a level of cash and cash equivalents deemed adequate to finance the Company’s operations and mitigate the effects of fluctuations in cash flows. In addition, management monitors the utilization of bank borrowings and ensures compliance with loan covenants.

• ii. The Company relies on bank borrowings as one of the significant source of liquidity. As of December 31, 2025 and 2024, the Company’s undrawn bank borrowing facilities are as follows:

~72~

	December	31,2025	December	31,2024
Unsecurred borrowing facilities
- Amount used (Note)	$	99,200	$	44,029
- Amount unused		6,720,480		6,968,376
	$	6,819,680	$	7,012,405

• Note: The amount used on December 31, 2025 and 2024 is the amount of endorsemnts and guarantees provided by the Company to subsidiaries.

• iii. Ultimate responsibility for liquidity risk management rests with the Board of Directors, which has built an appropriate liquidity risk management framework for the Company’s short, medium and long-term funding and liquidity management requirements. The Company manages liquidity risk by maintaining adequate reserves of bank credit facilities and continuously monitoring forecast and actual cash flows.

• iv. Liquidity and interest risk rate tables for non-derivative financial liabilities The following table details the Company’s remaining contractual maturity for its nonderivative financial liabilities with agreed repayment periods. The tables had been drawn up based on the undiscounted cash flows of financial liabilities from the earliest date on which the Company can be required to pay. The tables included both interest and principal cash flows. Specifically, bank loans with a repayment on demand clause were included in the earliest time band regardless of the probability of the banks choosing to exercise their rights. The maturity dates for other non-derivative financial liabilities were based on agreed repayment dates.

• For non-derivative financial liabilities subject to floating interest rates, the undiscounted amount was derived from the interest rate curve at the balance sheet date.

(3) Fair value information

• A. The different levels that the inputs to valuation techniques are used to measure fair value of financial and non-financial instruments have been defined as follows:

~74~

• Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date. A market is regarded as active where a market in which transactions for the assets or liabilities take place with sufficient frequency and volume to provide pricing information on an ongoing basis.

• Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as price) or indirectly (i.e. derived from prices).

• Level 3: Unobservable inputs for the asset or liability.

• B. Financial instruments not measured at fair value

• The carrying amounts of cash and cash equivalents, notes receivable, accounts receivable, accounts receivable - related parties, other receivables, other receivables - related parties, financial assets at amortised cost (current and non-current), refundable deposits, notes and accounts payable, accounts payable - related parties, other payables, other payables - related parties, other current liabilities, guarantee deposits received and lease liabilities are approximate to their fair values.

• C. The related information on financial and non-financial instruments measured at fair value by level on the basis of the nature, characteristics and risks of the assets and liabilities is as follows: (a) The related information about the nature of the assets and liabilities is as follows:

• (b) The methods and assumptions the Company used to measure fair value are as follows:

• i. The instruments the Company used market quoted prices as their fair values (that is, Level 1) are listed below by characteristics:

Listed and OTC stocks Open-end fund Corporate bonds Market quoted price Closing price Net asset value Closing price

• ii. Except for financial instruments with active markets, the fair value of other financial instruments is measured by using valuation techniques or by reference to counterparty quotes. The fair value of financial instruments measured by using valuation techniques can be referred to current fair value of instruments with similar terms and characteristics in substance, discounted cash flow method or other valuation methods, including calculated by applying model using market information available at the financial reporting date.

• iii. For high-complexity financial instruments, the fair value is measured by using selfdeveloped valuation model based on the valuation method and technique widely used within the same industry. The valuation model is normally applied to derivative financial instruments, debt instruments with embedded derivatives or securitised instruments. Certain inputs used in the valuation model are not observable at market, and the Company must make reasonable estimates based on its assumptions.

~76~

• iv. The valuation of derivative financial instruments is based on valuation model widely accepted by market participants, such as present value techniques and option pricing models. Forward exchange contracts are usually valued based on the current forward exchange rate.

• v. The output of valuation model is an estimated value and the valuation technique may not be able to capture all relevant factors of the Company’s financial and non-financial instruments. Therefore, the estimated value derived using the valuation model is adjusted accordingly with additional inputs, for example, model risk or liquidity risk and etc. In accordance with the Company’s management policies and relevant control procedures relating to the valuation models used for fair value measurement, management believes adjustment to valuation is necessary in order to reasonably represent the fair value of financial and non-financial instruments at the parent company only balance sheet. The inputs and pricing information used during valuation are carefully assessed and adjusted based on current market conditions.

• D. There were no transfers between Levels 1, 2 and 3 for the years ended December 31, 2025 and 2024.

• E. Valuation techniques and inputs applied for Level 2 fair value measurement Derivatives held by the Company were forward foreign exchange contracts, whose fair values were calculated using discounted cash flow. Future cash flows are estimated based on observable forward exchange rates at the end of the reporting period and contract forward rates, discounted at a rate that reflects the credit risk of various counterparties.
