Independent Auditors’ Report

(114) Tsai-Sheng-Bao-Zi No. 24005089

To Taiwan Mask Corporation,

Opinions

We have audited the accompanying consolidated balance sheets of Taiwan Mask Corporation and its subsidiaries (the “Group”) as of December 31, 2024 and 2023, and the related consolidated statements of comprehensive income, of changes in equity and of cash flows for the years ended December 31, 2024 and 2023, and notes to the consolidated financial statements, including a summary of significant accounting policies.

In our opinion, based on our audits and the reports of the other independent auditors, as described in the “Other matters’’ section of our report, the accompanying consolidated financial statements present fairly, in all material aspects, the consolidated financial position of the Group as of December 31, 2024 and 2023, and its consolidated financial performance and its consolidated cash flows for the years ended December 31, 2024 and 2023 in accordance with the “Regulations Governing the Preparation of Financial Reports by Securities Issuers” and the International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretations as endorsed by the Financial Supervisory Commission.

Basis for Opinion

We conducted our audits in accordance with the Regulations Governing Auditing and Attestation of Financial Statements by Certified Public Accountants and auditing standards generally accepted in Taiwan. Our responsibilities under those standards are further described in the Independent Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent of the Group in accordance with the Code of Professional Ethics for Certified Public Accountants in the Republic of China (the “Code”), and we have fulfilled our other ethical responsibilities in accordance with the Code. Based on our audits and the reports of the other independent auditors, 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 judgment, were of most

~5~

significance in our audit of the consolidated financial statements of fiscal year 2024. These matters were addressed in the context of our audit of the consolidated financial statements as a whole and, in forming our opinion thereon, we do not provide a separate opinion on these matters.

Key audit matters for the TMC Group’s consolidated financial statements in fiscal year 2024 are stated as follows:

Income recognition

Explanation

For the accounting policy on income recognition, please refer to Note 4 (29) of the financial report. For sales revenue, please refer to Note 6 (23); the operating income in fiscal year 2024 was NT$7,561,749 thousand.

The Group mainly produces and sells products such as masks and integrated circuits used in semiconductors, and has a large and diversified sales base. Trading conditions vary according to market conditions and customer needs. Considering that sales revenue is a major transaction that has a significant impact on the consolidated financial statements, we believe that the recognition of sales revenue is one of the most important matters to be considered in this year's audit.

How our audit addressed the matter

We have performed primary audit procedures for the above matter as follows:

1. Understand the type of major income and assess internal operations, review revenue recognition and accounting treatment.

2. Obtain the sales revenue statement, sample the sales transactions and verify the relevant documents to determine the appropriateness of the sales revenue.

3. Execute the cut-off test for the sales receipts transaction for a certain period of time before and after the closing date, and confirm that the account is correct at the time of entry.

Other matters–Parent company only financial reports

We have audited and expressed an unmodified opinion on the parent company only standalone financial statements of Taiwan Mask Corporation as of and for the years ended December 31, 2024 and 2023.

~6~

Responsibilities of management and those charged with governance for the consolidated financial statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with the “Regulations Governing the Preparation of Financial Reports by Securities Issuers” and the International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretations as endorsed and issued into effect by the Financial Supervisory Commission, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the Group’s ability 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 the Group 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 Group’s financial reporting process.

Independent Auditor’s responsibilities for the audit of the consolidated financial statements

Our objectives are to obtain reasonable assurance about whether the consolidated 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 ROC AS 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 consolidated financial statements.

As part of an audit conducted in accordance with ROC AS, we exercise professional judgment and professional skepticism throughout the audit. We also conduct the following undertakings:

1. Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures

~7~

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.

1. 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 the Group’s internal control.

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

3. 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 Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our report to the related disclosures in the consolidated 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 report. However, future events or conditions may cause the Group to cease to continue as a going concern.

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

5. Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision, and performance of the group audit. We remain solely responsible for our audit opinion.

We communicated 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 for the current period.

We also provide those charged with governance with a statement that we have

~8~

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 2024 consolidated financial statements of the current period and are therefore deemed 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 auditor’s report because the adverse consequences of doing so would reasonable are expected to outweigh the public interest benefits of such communication.

IFRS 18 “Presentation and Disclosure in Financial Statements” replaces IAS 1, updates the structure of comprehensive income statement, requires the disclosure of management-defined performance measures, and enhances the principles for grouping and classifying information for main financial statements and notes.

IV. Summary of Significant Accounting Policies

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

(I) Compliance statement

These consolidated financial statements of the Group have been prepared in accordance with

~17~

the "Rules Governing the Preparation of Financial Statements by Securities Issuers", International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretations as endorsed and issued into effect by the FSC (collectively referred herein as the "IFRSs”).

(II) Basis of Preparation

1. Except for the following items, these consolidated financial statements have been prepared under the historical cost convention.

2. (1) Financial assets and financial liabilities at fair value through profit or loss (including derivatives).

3. (2) Financial Assets at Fair Value Through Other Comprehensive Income.

4. (3) Defined benefit liabilities recognized based on the net amount of pension fund assets less present value of defined benefit obligation.

5. The preparation of financial statements in conformity with IFRSs requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the Group's accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note V.

(III) Basis of consolidation

1. The basis for preparation of consolidated financial statements

2. (1) All subsidiaries are included in the Corporate Group’s consolidated financial statements. Subsidiaries are all entities controlled by the Corporate Group. The Corporate Group controls an entity when the Group 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. Consolidation of subsidiaries begins from the date the Group obtains control of the subsidiaries and ceases when the Group loses control of the subsidiaries.

3. (2) Inter-company transactions, balances and unrealized gains or losses on transactions between companies within the Corporate Group are eliminated. Accounting policies of subsidiaries have been adjusted where necessary to ensure consistency with the policies adopted by the Corporate Group.

4. (3) The profit and loss and the components of other comprehensive income attribute to the owners of the parent company and non-controlling interest. The total comprehensive income also attributes to the owners of the parent company and non-controlling interest, even if this results in the non-controlling interests having a deficit balance.

5. (4) Changes in a parent's ownership interest in a subsidiary that do not result in the parent losing control of the subsidiary (transactions with non-controlling interests) are equity transactions, and they are considered as 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 directly recognized in equity.

6. (5) When the Group loses control of a subsidiary, the Group remeasures any investment retained in the former subsidiary at its fair value. That fair value is regarded as the fair value on initial recognition of a financial asset or the cost on initial recognition of the associate or joint venture. Any difference between fair value and carrying amount is recognized in profit or loss. All amounts previously recognized in other comprehensive

~18~

income in relation to the subsidiary are reclassified to profit or loss on the same basis as would be required if the related assets or liabilities were disposed of. That is, when the Group loses control of a subsidiary, all gains or losses previously recognized in other comprehensive income in relation to the subsidiary should be reclassified from equity to profit or loss, if such gains or losses would be reclassified to profit or loss when the related assets or liabilities are disposed of.

(IV) Foreign currency translation

Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (the "functional currency"). The consolidated financial statements are presented in New Taiwan dollars, which is the Company's functional currency.

1. Foreign currency transactions and balances

2. (1) Foreign currency transactions are translated into the functional currency using spot exchange rate 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 recognized in profit or loss in the period in which they arise.

3. (2) Monetary assets and liabilities denominated in foreign currencies at the period end are re-translated using spot exchange rate at the balance sheet date. Exchange differences

~23~

arising from re-translation at the balance sheet date are recognized in profit or loss.

  - (3) Non-monetary assets and liabilities denominated in foreign currencies held at fair value through profit or loss are re-translated using spot exchange rate at the balance sheet date. Their translation differences are recognized in profit or loss. Non-monetary assets and liabilities denominated in foreign currencies held at fair value through other comprehensive income are re-translated using spot exchange at the balance sheet date. Their translation differences are recognized in other comprehensive income. For those which are not measured at fair value, they measured by the historical exchange rate of the initial transaction date.

  - (4) All foreign exchange gains and losses are presented in the statement of comprehensive income within "Other gains and losses".

1. Translation of foreign operations

   • (1) The operating results and financial position of all corporate group entities and affiliates that have a functional currency different from the presentation currency are translated into the presentation currency as follows:

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

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

     • C. All resulting exchange differences are recognized in other comprehensive income.

   • (2) When the foreign operation that is partially disposed of or sold is a subsidiary, the accumulated conversion difference recognized as other comprehensive income is reattributed to the foreign operation's non-controlling interests on a pro rata basis. However, even if the Group retains part of its equity in the former subsidiary, but has lost control of the subsidiary of the foreign operation, it will be treated with as a disposal of the entire equity of the foreign operation

   • (3) Goodwill and fair value adjustments arising on acquisition of a foreign entity are regarded as assets and liabilities of the foreign entity, and are translated at the closing rate.

2. (V) Classification of current and non-current items

3. Assets that meet one of the following criteria are classified as current assets:

   • (1) Assets arising from operating activities that are expected to be realized, or are intended to be sold or consumed within the normal operating cycle.

   • (2) Assets held mainly for trading purposes.

   • (3) Assets that are expected to be realized within twelve months from the balance sheet date.

   • (4) Cash and cash equivalents, excluding restricted cash and cash equivalents and those that are to be exchanged or used to pay off liabilities more than twelve months after the balance sheet date.

Those that do not meet the above criteria are considered non-current.

1. Liabilities that meet one of the following criteria are classified as current liabilities:

2. (1) Liabilities that are expected to be paid off within the normal operating cycle.

3. (2) Assets held mainly for trading purposes.

4. (3) Liabilities that are to be paid off within twelve months from the balance sheet date.

~24~

• (4) The right to defer settlement of the liability for at least twelve months after the reporting period is not held.

Those that do not meet the above criteria are considered non-current.

• (VI) 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.

(VII) Financial Assets at Fair Value Through Profit or Loss

1. Refer to the financial assets that are not measured at amortized cost, or are measured at fair value through other comprehensive gain or loss.

2. On a regular way purchase or sale basis, financial assets at fair value through profit or loss are recognized and derecognized using trade date accounting.

3. The Group measures financial assets at fair value in initial recognition. The related transaction costs are recognized in profit and loss. These financial assets are subsequently re-measured and stated at fair value, and any changes in the fair value of these financial assets are recognized in profit or loss.

4. When the right to receive dividends is established, the economic benefits associated with the dividends are likely to flow in, and the amount of dividends can be reliably measured, the Group recognizes dividend income in profit or loss.

(VIII) Financial assets at fair value through other comprehensive profit and loss

1. Refers to an irrevocable election at the time of initial recognition to report the fair value changes of equity investments that are not held for trading in other comprehensive income.

2. On a regular way purchase or sale basis, financial assets at fair value through other comprehensive profit or loss are recognized and derecognized using trade date accounting.

3. The Corporate Group measures financial assets at fair value plus transaction costs at the initial recognition. The financial assets are subsequently measured at fair value. The fair value changes of equity investments are recognized in other comprehensive income. At the time derecognition, the accumulated gains or losses previously recognized in other comprehensive income shall not subsequently reclassified to profit or loss, and shall be transferred to retained earnings. When the right to receive dividends is established, the economic benefits associated with the dividends are likely to flow in, and the amount of dividends can be reliably measured, the Group recognizes dividend income in profit or loss.

(IX) Financial assets measured at amortized cost

1. Refer to those that meet the following criteria at the same time:

2. (1) The objective of the business model is achieved by collecting contractual cash flows.

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

4. The Corporate Group holds time deposits that are not considered cash equivalents. Due to the short holding period, the impact of discounting is insignificant and is measured by the amount of investment.

~25~

(X) Accounts and notes receivable

1. Refers to accounts and notes that have been unconditionally charged for the right to exchange the value of the consideration due to the transfer of goods or services.

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

(XI) Impairment Loss of Financial Assets

Regarding debt instruments measured at FVTOCI, financial assets measured at amortized cost, accounts receivable or contract assets and lease receivables that contain significant financing components, the Group, on each balance sheet date, considers all reasonable and supportable information (including forward-looking ones) and measure the loss allowance based on the 12-month expected credit losses for those that do not have their credit risk increased significantly since initial recognition. For those that have increased significantly since initial recognition, the loss allowance is measured based on the full lifetime expected credit losses. A loss allowance for full lifetime expected credit losses is also required for contract assets or trade receivables that do not constitute a financing transaction.

(XII) De-recognition of financial assets

A financial asset is derecognized when the Group's rights to receive cash flows from the financial assets have expired.

(XIII) Lessor's lease transaction - Operating lease

Lease income from operating leases, less any incentives given to the lessee, is amortized in current profit or loss on a straight-line basis over the lease term.

(XIV) Inventories

Inventories are measured at the lower of cost or net realizable value, and the cost is determined by weighted-average method. The cost of finished goods and work-in-progress comprises raw materials, direct labor, other direct costs and related production overheads (amortized according to normal production capacity), but excludes borrowing costs. At the end of year, inventories are evaluated at the lower of cost or net realizable value. The item by item approach is used in applying the lower of cost and net realizable value. Net realizable 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.

(XV) Investments accounted for using equity method - Associates

1. Affiliated enterprises refer to entities over which the Corporate Group has significant influence but is not in control. In general, the associates may have more than 20% of their voting shares directly or indirectly owned by the Group. The Corporate Group accounts for its investment in associates using the equity method, and the investment is initially recognized at cost.

2. The Corporate Group recognizes the profit and loss upon the acquisition of associates as the current profit and loss. Other comprehensive profit and loss after the acquisition are recognized as the other comprehensive profit and loss. When the Corporate Group’s share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Group will not recognize further losses, unless it has incurred legal or constructive obligations or make payments on behalf of the associate.

~26~

1. If an associate has changes in equity not from profit or loss or other comprehensive income, and such changes do not affect the Corporate Group's shareholding in the associate, the Group will recognize all changes in equity attributable to the Group's share of the associate as "capital surplus" according to the shareholding percentage.

2. Unrealized gains on transactions between the Corporate Group and associates are eliminated to the extent of the Group's interest in the associates. Unrealized 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 Corporate Group.

3. In the event that an associate issues new shares and the Corporate Group does not subscribe to or acquire the new shares in proportion, which results in a change to the Group's shareholding percentage but the Group maintains a significant influence on the associate, the increase or decrease of the Group's share of equity interest is the adjustment of "capital surplus" and "investments accounted for under the equity method". If the investment percentage is reduced, in addition to the above adjustments, the amounts previously recognized in other comprehensive income in relation to the associate are reclassified to profit or loss proportionally on the same basis as would be required if the relevant assets or liabilities were disposed of.

(XVI) Property, plant and equipment

1. Property, plant and equipment are initially recorded at cost. Borrowing costs incurred during the construction period are capitalized.

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

3. 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.

4. The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted if appropriate, at each balance sheet date. 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:

5. Buildings and structures 3 years to 60 years Machinery and equipment 2 years to 16 years Office equipment 2 years to 9 years Transportation equipment 3 years to 7 years Leasehold improvements 2 years to 10 years Mold equipment 2 years Other equipment 2 years to 12 years

~27~

(XVII) Leasing agreements (lessee) - Right-of-use assets/lease liabilities

1. Leases are recognized as right-of-use assets and lease liabilities at the date at which the leased assets are available for use by the Group. For short-term leases or leases of lowvalue assets, lease payments are recognized as expenses on a straight-line basis over the lease term.

2. 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 include fixed payments, less any lease incentives receivables.

The Company subsequently measures the lease liability at amortized cost using the interest method and recognizes interest expense over the lease term. The lease liability is remeasured and the amount of re-measurement is recognized as an adjustment to the rightof-use asset when there are changes in the lease term or lease payments and such changes do not arise from contract modifications.

1. At the commencement date, the right-of-use asset is recognized at cost which includes:

2. (1) The amount of initial measurement of lease liability.

3. (2) Any lease payments made at or before the commencement date.

4. (3) Any original direct costs incurred.

5. (4) The estimated cost of dismantling, removing the underlying asset and restoring its location, or restoring the underlying asset to the condition required in the lease terms and conditions.

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 service life or the end of lease term. When the lease liability is remeasured, the amount of re-measurement is recognized as an adjustment to the right-of-use asset.

(XVIII) Real estate investment

Investment properties are initially measured at cost, and may be subsequently measured using a cost model. Except for land, the service life is recognized on a straight-line basis of depreciation and is about 45 years.

(XIX) Intangible assets

1. Trademark and concession

Trademarks and concession obtained separately are recognized at the cost of acquisition, and trademarks and concessions obtained as a result of a business combination are recognized at fair value on the acquisition date. Trademarks and concessions are assets with a limited useful life and are amortized based on the estimated useful life of 10 to 15 years based on the straight-line method.

1. Computer software

Computer software is recognized at the cost of acquisition, and amortized based on the estimated useful life of 3 years based on the straight-line method.

1. Goodwill

Goodwill is measured in a business combination using the acquisition method.

~28~

(XX) Impairment of non-financial assets

1. The Group assesses on each balance sheet date the recoverable amounts of those assets where there is an indication that they are impaired. An impairment loss is recognized 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 disposal cost or value in use. When the circumstances or reasons for recognizing 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 amortized historical cost would have been if the impairment had not been recognized.

2. Goodwill, intangible assets with indefinite useful life and intangible assets not yet available for use are regularly estimated for their recoverable amounts. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The goodwill impairment loss will not be reversed in subsequent years.

3. Goodwill is allocated to cash-generating units for the purpose of conducting the impairment testing. The allocation identified based on the operating segment, and the goodwill is allocated to cash-generation units or groups of cash-generation units expected to benefit from the business combination that generates goodwill.

(XXI) Borrowings

Refers to long- and short-term funds borrowed from banks and other long- and short-term borrowings. Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in profit or loss over the period of the borrowings using the effective interest method.

(XXII) Accounts and notes receivable

1. Refers to debts incurred as a result of the purchase of raw materials, goods or services and the notes payable due to business and non-business purposes.

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

(XXIII) Convertible bonds payable

The convertible bonds payable issued by the Group are embedded with conversion options (i.e., the holder's right to choose to convert to the Group's common stock for a fixed amount of shares), put options and call options. The issuance price is classified as financial assets, financial liabilities or equity at the time of initial issuance according to the terms of issuance, which is treated as follows:

1. Embedded put options and call options: "Financial assets or liabilities at fair value through profit or loss" are recorded at their net fair value on initial recognition; subsequently, "Gain or loss on financial assets (liabilities) at fair value through profit or loss" is recognized on the balance sheet date, with the difference valued at current fair value.

2. Master contract of corporate bonds: The difference between the fair value of the corporate bonds and the redemption value is recognized as a premium or discount on the corporate bonds payable at the time of original recognition; subsequently, it is recognized in profit or loss as an adjustment to "finance costs" using the effective

~29~

interest method under the amortization procedure over the circulation period.

1. Embedded conversion options (which meet the definition of equity): On initial recognition, the remaining value of the issue amount, net of the above "financial assets or liabilities at fair value through profit or loss" and "corporate bonds payable", is recorded as "capital surplus - stock options" and is not subsequently remeasured.

2. Any directly attributable transaction costs of the issuance are allocated to each component of liabilities and equity in proportion to the original carrying amount of each component mentioned above.

3. Upon conversion, the components of liabilities (including “corporate bonds payable” and “financial assets or liabilities at fair value through profit or loss”) are subsequently measured according to their respective classifications, and the carrying amount of the aforementioned components of liabilities is added to the carrying amount of “capital surplus - stock options” as the issuance cost of common stock exchanged.

(XXIV) Employee benefits

1. 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 recognized as expenses in that period when the employees render service.

1. Pension

2. (1) Defined contribution plans

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

• (2) Defined benefit plans

  • A. 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 Group in current period or prior periods. The liability recognized 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 the current interest rates of government bonds (at the balance sheet date) consistent with the currency and period of the defined-benefit plan instead.

  • B. Re-measurements arising on defined-benefit plans are recognized in other comprehensive income in the period in which they arise and recorded as retained earnings.

• Termination benefits

Refer to when companies decide to terminate the employees before the normal retirement date, or when employees decide to accept the benefits in exchange for the termination. The Group recognizes expenses when it is no longer able to withdraw the offer of termination benefits or when the relevant restructuring costs are recognized, whichever is earlier. Liabilities that are not expected to be paid off within twelve months from the balance sheet date should be discounted.

~30~

4. Remuneration for employees and directors

• Employees' bonuses and directors' remuneration are recognized 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.

(XXV) Share-based payment to employees

The share-based payment agreement for delivery of equity is a transaction in which employees' labor service received as consideration for the Company's equity instrument at fair value, and it is recognized as compensation costs during the vesting period, and the equity is adjusted accordingly. The fair value of equity instrument shall reflect the effects of vesting and non-vesting conditions of market value. The recognized remuneration costs are adjusted in accordance with the expected service conditions to be met and the nonvesting market value conditions, until the final recognized amount is recognized with the vesting amount on the vesting date.

(XXVI) Income tax

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

2. 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 and its subsidiaries 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.

3. Deferred income tax is recognized, 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 income tax arising from the initially recognized goodwill 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 loss and does not generate taxable and deductible temporary difference. Deferred income 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 Group and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred income 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 income tax asset is realized or the deferred income tax liability is settled.

4. Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. At each balance sheet date, unrecognized and recognized deferred income tax assets are reassessed.

~31~

1. Current income tax assets and liabilities are offset and the net amount reported in the balance sheet when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis or realize the asset and settle the liability simultaneously. Deferred income tax assets and liabilities are offset on the balance sheet when the entity has the legally enforceable right to offset current tax assets against current tax liabilities. They are levied by the same taxation authority on either the same entity or different entities that intend to settle on a net basis or realize the asset and settle the liability simultaneously.

(XXVII) Capital

1. 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.

2. When the Company buys back the issued shares, the consideration paid, including any directly attributable incremental costs, is recognized as a deduction of shareholders’ equity with the net amount after tax. When purchased shares are reissued, the difference between the consideration received and the book amount after deducting any directly attributable incremental costs and the impact of income tax is recognized as an adjustment to shareholders’ equity.

(XXVIII) Dividend distribution

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. Stock dividends are recorded as dividends to be distributed and transferred to be common stocks on the record date of issuance of new shares.

(XXIX) Recognized revenue

1. Sales of services

The Group mainly provides photomask manufacturing and integrated circuit packaging services. The actual services provided and fees will vary according to different customers. Prices are negotiated separately before providing services, and are based on the prevailing market price. The performance obligations identified based on customer contracts are mainly for photomask manufacturing and packaging services, and revenue is recognized by measuring the degree of completion of performance obligations during the period of service provision.

With the provision of photomask manufacturing and packaging services, the customer simultaneously receives and consumes the performance benefits, and the customer has control over the asset when the asset is created or enhanced. The Group’s performance does not create any assets available for other purposes and has the exercisable right to the amount that has been completely performed till now. The related revenue is recognized by measuring the degree of completion of the performance obligation during the service period. The photomask manufacturing and packaging services are based on the input of the technical staff on the basis of the service, and the progress of completion is measured based on the percentage of the incurred cost to the estimated total cost. After the agreed service or shipment is fulfilled for the contract agreement, a bill is issued, so the contract assets are recognized when the service provided, and transferred to account receivables when the customer agrees to the Group to issue the bill.

~32~

1. Product sales

   • (1) The Group manufactures and sells semiconductor-related integrated circuit products, medical equipment products, etc. The sales revenue is recognized when the control of the product is transferred to the customer. That is, once products are delivered to customers, the customers have discretion on the channel and price of product sales, and the Corporate Group has no outstanding performance obligations that may affect customers' acceptance of the products. The delivery of products occurs when products are shipped to a designated location and the risk of obsolescence and loss has been transferred to customers, and the customers accept the products in accordance with the sales contract or have objective evidence that all criteria have been met.

   • (2) The time interval between the transfer products or services promised to customers and the customers' payment has not exceeded one year, so the Corporate Group has not adjusted the transaction price to reflect the time value of money.

   • (3) Accounts receivable are recognized when goods are delivered to customers. The Corporate Group has unconditional rights to the contract price, and will be able to collect the amount from the customers after the time has passed.

2. (XXX) Government subsidies

Government subsidies are recognized at fair value once it is reasonably convinced that the Company complies with the conditions for subsidies and will be receiving the subsidies. If the nature of the government subsidies is to compensate the expenses incurred by the Group, the government subsidies are recognized as current gains and losses on a systematic basis during the period in which the related expenses are incurred.

(XXXI) Business combination

1. The Corporate Group adopts the acquisition method for business combination. The combination consideration is calculated based on the fair value of transferred assets, liabilities incurred or assumed, and equity instruments issued. The transferred consideration includes the fair value of any assets and liabilities arising from contingent consideration agreed. The acquisition-related costs are recognized as expenses when incurred. The identifiable assets acquired and the liabilities assumed in a business combination are measured at the fair value on the acquisition date. The Group uses individual acquisition transactions as the basis. If the non-controlling interest is part of the current ownership interest and the holder has the right to a proportional share of the company's net assets at the time of liquidation, it is measured at a fair value on the acquisition date or based on the proportion of identifiable assets of acquiree. Other components of non-controlling interests are measured at fair value of the acquisition date.

2. If the total fair value of transfer of consideration, non-controlling interests of acquiree and the interest of acquiree that has been held previously exceeds the fair value of identifiable assets and the assumed liabilities, it is recognized as goodwill on the acquisition date. If the identifiable assets acquired and the assumed liabilities exceed the transfer of consideration, the difference between the non-controlling interests of acquiree and the total fair value of acquiree's interests previously held is recognized as the current profit or loss.

~33~

(XXXII) Operating segments

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the president that makes strategic decisions.

V. Critical Accounting Judgments and Key Sources of Estimation and Uncertainty

The preparation of these consolidated financial statements requires the management to make critical judgments in applying the Group’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. Please see the following explanation of critical accounting judgments and key sources of estimation and uncertainty:

(I) Important judgments adopted by the accounting policies

None.

(II) Critical accounting estimates and assumptions

Evaluation of Inventories

The Group is primarily engaged in mask and integrated circuit services in the semiconductor industry. Due to rapid technological innovations, short life-cycle and competition within the mask industry, the risk of price fluctuations, Loss on decline in value of inventories and obsolescence is higher than that of other industries. The Group measures inventory based on the lower of cost and net realizable value. For inventories that are older than a certain period of age or are outdated and obsolete, the Group must use judgment and estimation to determine the net realizable value of the inventory on the balance sheet date. The valuation of inventory may undergo major changes.

As of December 31, 2024, the book value of the Corporate Group’s inventory was NT$723,781.

(XVIII) Pensions

1.

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 six months prior to retirement. The Company and its domestic subsidiaries contribute a monthly amount equal to 2% of employees’ monthly salaries and wages to a retirement fund at the Bank of Taiwan, the trustee, under the name of the independent retirement fund committee. Also, the Company and its domestic subsidiaries would assess the balance in the aforementioned labor pension reserve account by December 31, every year. If the account balance is not enough to pay the pension calculated by the aforementioned method to the employees expected to qualify for retirement in the following year, the Company and its domestic subsidiaries will make contribution for the deficit by the end of next March.

2. (2) The amounts recognized in the balance sheet are as follows:

Present value of defined benefit obligations Fair value of plan assets Defined Benefit Liabilities	December 31, 2024 ($ 22,527) 15,575 ($ 6,952)	December 31, 2023 ($ 22,650) 12,417

Checks were received from the retirement reserve funds under custody of the Bank of Taiwan on August 4, 2023 in accordance with paragraph 9 of the Regulations for the Allocation and Management of the Workers' Retirement Reserve Funds. The over-payment to the employees’ retirement reserve funds determined after settlement of the seniority payment for the employees was recognized as pension profit of NT$326.

funds in August 2023, so only the changes in the Company's net defined benefit liabilities were disclosed in 2023.

• (5) 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 utilization plan and the “Regulations for Revenues, Expenditures, Safeguard and Utilization of the Labor Retirement Fund” (Article 6: The scope of utilization for the Fund includes deposit in domestic or foreign financial institutions, investment in domestic or foreign listed, over-the-counter or private placement equity securities, investment in domestic or foreign real estate securitization products, etc.). With regard to the utilization 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 are less than the aforementioned rates, government shall make payments for the deficit after being authorized by the Regulator. The Company has no right to participate in managing and operating the fund and hence the Company is unable to disclose the classification of fair value of plan asset in accordance with IAS19 paragraph 142. The composition of fair value of plan assets as of December 31, 2024 and 2023 is given in the Annual Labor Retirement Fund Utilization Report announced by the government.

• (6) The principal actuarial assumptions used were as follows:

Discount rate Future salary increases	2024 1.06% 2.125%	2023 1.3% 2.125%

The assumptions for future mortality rates for the years 2024 and 2023 are estimated based on the Sixth Taiwan Life Insurance Experience Mortality Table

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

Discount rate 0.25% increase December 31, 2024 Effect on present value of defined benefit obligation ($ 608) December 31, 2023 Effect on present value of defined benefit obligation ($ 637)	0.25% decrease	Future salary increases 0.25% increase 0.25% decrease $ 611 ($ 593) $ 640 ($ 620)
		0.25% increase
	$ 629 $ 661	$ 611
		$ 640

~56~

The sensitivity analysis above analyzes the impact from changing one of the assumptions while others remain constant. In practice, more than one assumption may change all at once. The sensitivity analysis is the same with the method used to calculate the net pension liabilities of the balance sheet.

• (7) The expected contributions to the defined benefit pension plans of the Group for the year ending December 31, 2025 are NT$2,133.

• (8) As of December 31, 2024, the weighted average duration of the retirement plan is 12 years.

• (1) Effective July 1, 2005, the Company and its domestic subsidiaries have established a defined contribution pension plan (hereinafter referred to as the “New Plan”) under the Labor Pension Act (hereinafter referred to as the “Act”), covering all regular employees with domestic citizenship. Under the New Plan, the Company and its domestic subsidiaries contribute an amount based on 6% of the employees’ monthly salaries and wages to the employees’ individual pension accounts at the Bureau of Labor Insurance. The benefits accrued are paid monthly or in lump sum upon termination of employment.

• (2) For 2024 and 2023, the pension costs recognized by the Corporate Group in accordance with the abovementioned pension measures were NT$56,743 and NT$41,918, respectively.

3. (1) Decide on the best capital budgeting.

4. (2) Decide on the financing required for one of the capital budgeting items.

5. (3) Decide on the amount of the financing to be supported by retained earnings (methods such as cash capital increase or corporate bonds and so on can be adopted as support).

6. (4) After retaining the portion required for operation needs out of the earnings remainder, the rest should be distributed to shareholders in the form of dividends. Cash dividends distribution proportion should not be lower than 20% of the total amount of dividends for the distribution proportion of the Company’s dividends.

7. Except for covering accumulated deficit or issuing new stocks or cash to shareholders in proportion to their share ownership, the legal reserve shall not be used for any other purpose. The use of the legal reserve for the issuance of stocks or cash to shareholders in proportion to their share ownership is permitted, provided that the distribution of the

~60~

reserve is limited to the portion in excess of 25% of the Company’s paid-in capital.

1. In accordance with the regulations, the Company shall set aside special reserve from the debit balance on other equity items at the balance sheet date before distributing earnings. When debit balance on other equity items is reversed subsequently, the reversed amount could be included in the distributable earnings.

2. The Company’s Board of Directors approved the proposal for covering the losses in 2024 on March 12, 2025.

3. The Company's shareholders’ meeting resolved on May 27, 2024 to distribute a cash dividend of NT$1.50 per common share from the 2023 earnings, with a total dividend of NT$373,477. In addition, due to the conversion of convertible bonds, the number of the Company’s outstanding shares changed to 248,994 thousand shares (excluding the treasury stock of 7,462 thousand shares). With the cash dividends remained at NT$1.5 per share, the total amount of cash dividends distributed from earnings in 2023 was adjusted to NT$373,491.

(I) Capital management

The Group’s objectives when managing capital are to safeguard the Group’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 Group may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt. The Group 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 consolidated balance sheet) less cash and cash equivalents. Total capital is calculated as "equity" as shown in the consolidated balance sheet plus net debt.

The Group's strategy in 2024 and 2023 was to take out long-term loans and issue corporate bonds to purchase machinery and equipment and obtain long-term working capital. For the years ended December 31, 2024 and 2023, the debt-to-capital ratios were as follows:

Total borrowings Less: Cash and cash equivalents Net debt Total equity Total capital Debt-to-equity ratio	December 31, 2024 $ 14,124,598 ( 1,430,542) 12,694,056 4,071,908 $ 16,765,964 76%	December 31, 2023 $ 13,196,526 ( 1,364,106) 11,832,420 5,109,904 $ 16,942,324 70.09%

1. Risk management policies

2. (1) The Group’s activities expose it to a variety of financial risks, including market risk (exchange rate, interest rate and price), credit risk and liquidity risk. The Group's overall risk management programme focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Group's financial position and performance.

3. (2) Risk management is carried out by a central finance department (Group finance) under policies approved by the Board of Directors. Group finance identifies, evaluates and hedges financial risks in close collaboration with the Group’s operating units. The Board provides written principles for overall risk management, as well as written policies covering specific areas and matters, such as currency exchange risk, interest rate risk, credit risk, the use of derivatives and non-derivative financial instruments and investment of excess liquidity.

4. Significant financial risks and degrees of financial risks

5. (1) Market risk

   • A. Foreign exchange risk

The Group's operations involve certain non-functional currencies (the Company’s and certain subsidiaries’ functional currency is the New Taiwan dollar (NTD), and for other certain subsidiaries, the functional currency is the US Dollars, Japanese Yen and China's Renminbi (RMB)), so it is subject to the impact of exchange rate fluctuation. The details of assets and liabilities denominated in foreign currencies whose values that would be materially affected by exchange rate fluctuations are as follows:

(Foreign currency: functional currency) Financial assets Monetary items USD: NTD RMB: NTD JPY: NTD Financial liabilities Monetary items USD: NTD JPY: NTD Euro: NTD	December 31, 2024 Foreign currency (in thousand) USD 38,770 CNY 46,309 JPY 512,938 USD 19,898 JPY 345,127 EUR 1,787	Exchange rate 32.785 4.478 0.2099 32.785 0.2099 34.14	Book value (NT$ in thousands) $ 1,270,949 207,372 107,666 652,347 72,442 61,008

Price risk

• A. The equity instruments owned by the Company exposing to the price risk are financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income.

• B. The Group invests primarily in equity instruments and open-end funds issued by domestic and foreign companies. The price of such equity instrument is subject to the uncertainty of the future value of investment target. If the price of such equity instrument increases or decreases by 1%, while all other factors remain unchanged, the net profit after tax affected by equity instruments at fair value through profit or loss after tax for 2024 and 2023 is an increase or decrease of NT$26,531 and NT$36,182, respectively; as for the other comprehensive income classified as equity instruments at fair value through other comprehensive income, it is NT$0 for both 2024 and 2023.

Cash flow and fair value interest rate risk

• A. The Group's interest rate risk mainly comes from long-term borrowings issued at floating rates, which exposes the Group to cash flow interest rate risk. For 2024 and 2023, the Group’s borrowings issued at floating rates were mainly denominated in New Taiwan dollars and US dollars.

• B. The Group's borrowings are measured at amortized cost, and the annual interest rate is re-priced according to the contract, which exposes the Group to the risk of future market interest rate changes.

• C. If the long- and short-term borrowing rates increase or decrease by 0.25%, while all other factors remain constant, the net profit after tax for 2024 and 2023 is a decrease or increase of NT$21,030 and NT$19,544, respectively, mainly due to the interest expense changes caused by the floating interest rate.

~81~

(2) Credit risk

• A. Credit risk refers to the risk of financial loss to the Group arising from default by the clients or counterparties of financial instruments under contract obligations, and the defaults are accounts receivable and the contract cash flow from debt instruments measured at amortized cost, measured at fair value through other comprehensive income and at fair value through profit or loss.

• B. The management of credit risk is established with a Group perspective. Only the banks and financial institutions with an independent credit rating of at least "A" can be accepted as transaction partners of the Group. According to the Group’s credit policy, each local entity in the Group is responsible for managing and analyzing 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 customers, taking into account their financial position, past experience and other factors. Individual risk limits are set based on internal or external ratings in accordance with limits set by the Board of Directors. The utilization of credit limits is regularly monitored.

• C. The Group considers a contract payment overdue in accordance with the agreed payment terms a breach of contract.

• D. The Group uses IFRS 9 to provide the following assumption as a basis for determining whether there is a significant increase in the credit risk of financial instruments after the original recognition:

• (A) If the contract payment is overdue for more than 30 days in accordance with the agreed payment terms, the credit risk of the financial asset is significantly increased since the original recognition.

• (B) For bond investments in Taipei Exchange, if any external rating agency rates it as an investment grade on the balance sheet date, the credit risk of the financial asset is considered low.

• E. The Group uses the following indicators to determine the status of credit impairments of debt instruments:

• (A) The issuer has suffered significant financial difficulties or is likely to enter bankruptcy or other financial restructuring.

• (B) The issuer has suffered significant financial difficulties or is likely to enter bankruptcy or other financial restructuring.

• (C) The issuer delays or does not pay for the interest or principal.

• (D) Unfavorable changes in the national- or regional-level economic situation resulting in the issuer's default.

• F. The Group categorizes the accounts receivable from customers based on the characteristics of trade credit risks. The simplified approach is adopted for estimating the expected credit loss based on the provision matrix.

• G. The Group may write off the amount of financial assets that cannot be reasonably expected to be recovered after recourse. However, the Group will continue the recourse to protect the rights of the claims.

• H. The Group has incorporated forward-looking considerations to adjust the loss rate built according to historic and current data in order to estimate the loss allowance

~82~

of accounts receivables. The provision matrix for the years ended December 31, 2024 and 2023 are shown as follows:

December 31, 2024 Expected loss rate Total book value Loss allowance December 31, 2023 Expected loss rate Total book value Loss allowance	Not past due 0.01% $ 1,041,381 - Not past due 0.01% $ 1,226,407 -	Up to 30 days 2.27~8.26% $ 142,862 - Up to 30 days 0.05~33.11% $ 171,778 -	31-90 days 9.12~66.68% $ 116,488 ( 8,669) 31-90 days 0.05~66.19% $ 78,432 ( 4,540)	91-180 days 37.32~100% $ 43,381 ( 7,468) 91-180 days 0.04~98.36% $ 11,385 ( 5,187)	More than 181 days past due Total 75.03~100% $ 136,412 $ 1,480,524 ( 94,625) ( 110,762) More than 181 days past due Total 50.9~100% $ 20,253 $ 1,508,255 ( 19,696) ( 29,423)

• I. The Group adopts a simplified method in which the loss allowance for the accounts receivable is shown as follows:

January 1 Recognize impairment loss Others December 31	2024 $ 29,423 81,338 1 $ 110,762	2023 $ 20,597 9,455 ( 629) $ 29,423

(3) Liquidity risk

• A. Cash flow forecasting is performed by the operating entities of the Corporate Group and aggregated by the Group’s treasury department. The Group’s Finance Department monitors the forecasts of the Group’s demand for working capital to ensure that it has sufficient funds to meet operational needs, and maintains sufficient unspent loan commitments at all times so that the Group will not exceed the relevant borrowing limits or violate the terms. These forecasts consider the Group’s debt financing plan, compliance with debt terms, and compliance with the financial ratio objectives of the internal balance sheet.

• B. The remaining cash held by each operating entity will be transferred back to the Group's finance department. The finance department of the Group invests the remaining funds in interest-bearing demand deposits, time deposits, financial assets at fair value through profit or loss, financial assets at amortized cost (time deposits with a maturity of more than 3 months and less than 12 months), as the instruments chosen have appropriate maturities or sufficient liquidity to provide sufficient headroom as determined by the abovementioned forecasts. For the years ended December 31, 2024 and 2023, the position of money market held by the Corporate Group is at NT$2,325,127 and NT$2,284,148, respectively, and is expected to generate immediate cash flow to manage liquidity risk.

~83~

• C. The Group's unutilized borrowings are shown as follows:

Floating rate Short-term credit limits Medium to long-term credit limits Fixed rate Short-term credit limits Medium to long-term credit limits	December 31, 2024 $ 920,414 - - 4,493 $ 924,907	December 31, 2023 $ 1,469,512 - 105,000 8,420 $ 1,582,932

• D. The following table shows the Group’s non-derivative financial liabilities and derivative financial liabilities settled on a net or total amount, grouped according to the relevant maturity date.

(III) Fair value information

1. 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:

2. 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 asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. The fair value of the Group’s investment in stocks of publicly traded or OTC firms and beneficiary certificates is included in Level 1.

Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3: Unobservable inputs for the asset or liability. The fair value of the Group’s investment in stocks of non-publicly traded or non-OTC firms and private equity fund is included in Level 3.

1. Financial instruments not measured at fair value

Cash, notes receivable, accounts receivable, other receivable, short-term borrowings, notes payable, accounts payable and other payable as reasonable approximation of fair value.

1. The related information for 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:

~85~

December 31, 2024 Assets Recurring fair value measurements Financial Assets at Fair Value Through Profit or Loss Equity securities Liabilities Recurring fair value measurements Financial liabilities at fair value through profit or loss Convertible bond call/put options December 31, 2023 Assets Recurring fair value measurements Financial Assets at Fair Value Through Profit or Loss Equity securities Beneficiary certificates Liabilities Recurring fair value measurements Financial liabilities at fair value through profit or loss Convertible bond call/put options	Level 1 $ 3,129,075 $- Level 1 $ 4,341,227 500 $ 4,341,727 $-	Level 2 $ 57,520 $- Level 2 $ 67,292 - $ 67,292 $-	Level 3 $ 129,721 $ 19,204 Level 3 $ 113,695 - $ 113,695 $ 9,383	Total $ 3,316,316 $ 19,204 Total $ 4,522,214 500 $ 4,522,714 $ 9,383

1. The methods and assumptions adopted by the Group for assessing the fair value are as follows:

2. (1) The Group adopt market pricing as the input of fair value (i.e. Level 1), and the breakdown of the characteristics of the instrument is as follows:

Shares of listed and OTC company Open-end funds

Market price Closing price Net Value

~86~

• (2) Except for the abovementioned financial instruments with active markets, the fair value of the remaining financial instruments is obtained using valuation techniques. The fair value obtained through valuation techniques can refer to the current fair value of other financial instruments with similar substantive conditions and characteristics, discounted cash flow method, or other valuation techniques, including the use of market information available on the date of the consolidated balance sheet (for example, the Taipei Exchange refers to the yield curve, the Reuters adopts the average quotation of interest rate of commercial promissory notes).

• (3) The output of the valuation model is the estimated value, and the valuation technique may not reflect all the relevant factors of the financial instruments and non-financial instruments held by the Group. Therefore, the estimated value of the valuation model will be appropriately adjusted according to additional parameters, such as model risk or liquidity risk. According to the Group's fair value valuation model management policies and related control procedures, the management believes that in order to properly express the fair value of financial instruments and non-financial instruments in the consolidated balance sheet, valuation adjustments are appropriate and necessary. The price information and parameters used in the valuation process are carefully assessed and appropriately adjusted according to current market conditions.

• (4) The Group incorporates credit risk valuation adjustments into the consideration of the fair value of financial instruments and non-financial instruments to reflect counterparty credit risk and the credit quality of the Group, respectively.

• There were no transfers between Level 1 and 2 in 2024 and 2023.

• The following table shows the changes in Level 3 in 2024 and 2023:

January 1, 2024 Acquisition cost of the period Return of capital by investee company Recognized in profit or loss of the period Impact from exchange rate December 31, 2024 January 1, 2023 Acquisition cost of the period Recognized in profit or loss of the period Impact from exchange rate December 31 2023	Financial instruments $ 104,312 22,500 ( 7,198) ( 9,821) 724
