INDEPENDENT AUDITORS’ REPORT TRANSLATED FROM CHINESE

To the Board of Directors and Shareholders of MEGA UNION TECHNOLOGY INCORPORATED

Opinion

We have audited the accompanying parent company only balance sheets of MEGA UNION TECHNOLOGY INCORPORATED (the “Company”) 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 the Company 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 the Company 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 judgment, were of most significance in our audit of the Company’s 2025 parent company only 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 the Company’s 2025 parent company only financial statements are stated as follows:

Key audit matter: Accuracy of construction revenue

Description

Refer to Notes 4(26), 5(2) and 6(18) for the accounting policies, accounting estimates and details related to the recognition of construction revenue.

The Company is primarily engaged in the planning, design and installation of ultrapure water and wastewater recycling systems. The construction revenue is recognised by reference to the stage of completion of each contract. The stage of completion is estimated based on the actual accumulated construction costs relative to the total estimated costs. Given that the aforementioned total estimated costs involve accounting estimates resulting in uncertainties and the total estimated costs will affect the stage of completion and the recognition of construction revenue, we considered the accuracy of construction revenue as a key audit matter.

How our audit addressed the matter

We performed the following audit procedures on the above key audit matter:

1. Obtained an understanding on the internal control of the assessment of the total estimated costs, sampled and verified the total estimated costs of significant constructions and assessed the consistency between the assessment process and the designed internal control.

2. Sampled and verified the approved total estimated costs for the new significant constructions and the constructions with significant changes in the total estimated costs during the year, including the supporting documents of the modified construction costs during the year.

~3~

1. Obtained the details of construction costs during the year, performed relevant substantive procedures, including sampling and verifying the construction costs incurred during the year with relevant evidence, and confirmed whether the costs incurred for the year had been accounted for appropriately, recalculated the stage of completion which is calculated based on the actual accumulated construction costs relative to the total estimated costs and ascertained whether revenue was recognised appropriately based on the stage of completion.

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 Company’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 Company 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 Company’s financial reporting process.

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 the Company’s internal control.

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 Company’s ability 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 the Company 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 the Company 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.

~5~

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.

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.

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

The parent company only financial statements of the Company 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 at fair value through other comprehensive income.

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

~15~

• B. The preparation of the parent company 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

Measurements on the Company’s financial statements are made using the currency of the primary economic environment in which the Company operates (the “functional currency”). The parent company only financial statements are presented in New Taiwan dollars, 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 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) All foreign exchange gains and losses are presented in the statement of comprehensive income within ‘other gains and losses’.

• B. Translation of foreign operations

The operating results and financial position of the Company and associates 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; and

• (c) All resulting exchange differences are recognised in other comprehensive income.

(4) Classification of current and non-current items

• A. As the operating cycle for construction contracts usually exceeds one year, the Company uses the operating cycle as its criteria for classifying current or non-current assets and liabilities related to construction contracts. For the other assets and liabilities, the criterion is one year.

• B. 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;

~16~

• (b) Assets held mainly for trading purposes;

• (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.

• C. 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 arising mainly from trading activities;

• (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 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 accountin.

• 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.

(7) 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.

~17~

• 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.

(8) 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.

(9) Impairment of financial assets

For financial assets at amortised cost including accounts receivable, notes receivable or contract assets 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 receivable, notes receivable or contract assets that do not contain a significant financing component, the Company recognises the impairment provision for lifetime ECLs.

(10) Derecognition of financial assets

The Company derecognises a financial asset when the contractual rights to receive the cash flows from the financial asset expire.

(11) Inventories

Inventories are stated at the lower of cost and net realisable value. Cost is determined using the weighted-average method. 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.

(12) Investments accounted for using the equity method - subsidiaries

• 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. Inter-company transactions, balances and unrealised gains or losses on transactions between companies within the Company are eliminated. Accounting policies of subsidiaries have been adjusted where necessary to ensure consistency with the policies adopted by the Company.

~18~

• C. The Company’s share of its subsidiaries’ 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 a subsidiary equals or exceeds its interest in the subsidiary, the Company continues to recognise losses proportionate to its ownership.

• D. 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.

(13) Property, plant and equipment

• A. Property, plant and equipment are initially recorded at cost. Borrowing costs incurred during the construction period are capitalised.

• 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 and structures	5 ~ 50 years
Machinery and equipment	3 ~ 15 years
Office equipment	3 ~ 10 years
Leasehold improvements	3 ~ 7 years
Transportation and other equipment	2 ~ 10 years

~19~

(14) 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.

• 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 amount of the initial measurement of lease liability.

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.

(15) Intangible assets

Computer software is stated at cost and amortised on a straight-line basis over its estimated useful life of 1 to 5 years.

(16) Impairment of non-financial assets

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. 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.

~20~

(17) Borrowings

Borrowings comprise long-term and short-term bank borrowings. Borrowings are recognised initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortised cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognised in profit or loss over the period of the borrowings using the effective interest method.

(18) Accounts payable

• A. Accounts payable are liabilities for purchases of raw materials, goods or services.

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

(19) Derecognition of financial liabilities

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

(20) Provisions for liabilities

Provisions (including warranties and onerous contracts) 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. Provisions are not recognised for future operating losses.

(21) 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.

~21~

(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 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. 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.

- (22) 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.

(23) 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.

~22~

• B. The current income tax expense is calculated on the basis of the tax laws enacted or substantively enacted at the balance sheet date. 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 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 loss and does not give rise to equal taxable and deductible temporary differences. Deferred tax is provided on temporary differences arising on investments in subsidiaries, 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.

(24) Share capital

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

(25) 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; share dividends are recorded as share dividends to be distributed and are reclassified to ordinary shares on the effective date of new shares issuance.

~23~

(26) Revenue recognition

• A. Construction revenue recognition

• (a) The Company provides related services in relation to the planning, design, construction and installation of ultrapure water and wastewater recycling system. Revenue is recognised in the accounting period in which the services are rendered. For fixed-price contracts, revenue is recognised based on the actual service provided to the end of the reporting period as a proportion of the total services to be provided. This is determined based on the actual costs incurred relative to the total estimated costs. The customer pays at the time specified in the payment schedule. If the services rendered exceed the payment, a contract asset is recognised. If the payments exceed the services rendered, a contract liability is recognised.

• (b) Some contracts include sales and installation services of equipment. The equipment and the installation services provided by the Company are not distinct and are identified to be one performance obligation satisfied over time since the installation services involve significant customisation and modification. The Company recognises revenue on the basis of costs incurred relative to the total estimated costs of that performance obligation.

• (c) The Company’s estimate about revenue, costs and progress towards complete satisfaction of a performance obligation is subject to a revision whenever there is a change in circumstances. Any increase or decrease in revenue or costs due to an estimate revision is reflected in profit or loss during the period when the management become aware of the changes in circumstances.

• B. Other operating revenue

• (a) The Company derives other operating revenue from providing maintenance services of ultrapure water and wastewater recycling system and sales of relevant consumables and chemicals. Sales are recognised when control of the products has transferred, being when the products are delivered to the buyer, the buyer has full discretion over the channel and price to sell the products, and there is no unfulfilled obligation that could affect the buyer’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 buyer, and either the buyer has accepted the products in accordance with the sales contract, or the Company has objective evidence that all criteria for acceptance have been satisfied.

• (b) 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.

~24~

(27) 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.

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

The preparation of these 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:

(1) Critical judgements in applying the Company’s accounting policies

None.

(2) Critical accounting estimates and assumptions

Construction revenue recognition

The Company’s revenue recognition is based on the percentage of input cost relative to the total estimated cost at completion. The estimation of the cost of completion involves accounting estimates, resulting in uncertainty. The Company regularly reviews the reasonableness of the estimates, which may cause changes in the estimated total cost of completion, and affect the amount recognised by the Company.

• C. As at December 31, 2025 and 2024, without taking into account any collateral held or other credit enhancements, the maximum exposure to credit risk in respect of the amount that best represents the Company’s notes receivable and accounts receivable was equivalent to the book value.

• D. The Company classifies accounts receivable in accordance with credit rating of customer. The Company applies the simplified approach using a provision matrix to estimate the expected credit loss.

• E. The Company used the forecastability to adjust historical and timely information to assess the default possibility of notes and accounts receivable. However, the expected loss rates of the Company’s notes receivable were all immaterial on December 31, 2025 and 2024; and the Company had no notes receivable that were past due as of December 31, 2025 and 2024.

(13) Pensions

• A. (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 contributions for the deficit by next March.

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

Present value of defined benefit obligations Fair value of plan assets ( Net defined benefit liability	December31,2025 10,381 $ 435) ( 9,946 $	December31,2024 4,440 $ 334) 4,106 $

~36~

• (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 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 assets 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 1.55% 2.00%	2024
		1.75%
		2.00%

Future mortality rate was estimated based on the 6th 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:

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% 506) $ 536 $ Increase Decrease 0.25% 0.25% 218) $ 231 $ Discount rate Discount rate	Increase Decrease 0.25% 0.25% 532 $ 505) ($ Increase Decrease 0.25% 0.25% 230 $ 218) ($ Future salaryincreases Future salaryincreases
	Increase 0.25% 218) $

~37~

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 plans of the Company for the year ending December 31, 2026 amount to $151.

• (g) As of December 31, 2025, the weighted average duration of the retirement plan is 20 years. The analysis of timing of the future pension payment was as follows:

Within 1 year 1-2 year(s) 2-5 years Over 5 years	- $ - - 14,250
	14,250 $

• B. (a) Effective July 1, 2005, the Company has established a defined contribution pension plan (the “New Plan”) under the Labor Pension Act (the “Act”), covering all regular employees with R.O.C. nationality. Under the New Plan, the Company contributes monthly 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.

  • (b) The pension costs under defined contribution pension plans of the Company for the years ended December 31, 2025 and 2024 were $28,982 and $24,802, respectively.

• (14) Share-based payments

(16) Capital surplus

Pursuant to the R.O.C. Company Act, capital surplus arising from paid-in capital in excess of par value on issuance of common shares and donations can be used to cover accumulated deficit or to issue new shares or cash to shareholders in proportion to their share ownership, provided that the Company has no accumulated deficit. Further, the R.O.C. Securities and Exchange Act requires that the amount of capital surplus to be capitalised mentioned above should not exceed 10% of the paidin capital each year. However, capital surplus should not be used to cover accumulated deficit unless the legal reserve is insufficient.

(17) Retained earnings/events after the balance sheet date

• A. Under the Company’s Articles of Incorporation, the current year’s earnings, if any, shall first be used to pay all taxes and offset prior years’ operating losses and then 10% of the remaining amount shall be set aside as legal reserve. The remainder, if any, shall be appropriated.

• B. Except for covering accumulated deficit or issuing new shares or cash to shareholders in proportion to their share ownership, the legal reserve shall not be used for any other purpose. The use of legal reserve for the issuance of shares or cash to shareholders in proportion to their share ownership is permitted, provided that the distribution of the reserve is limited to the portion in excess of 25% of the Company’s paid-in capital.

• D. Costs to fulfill a contract (recognised as “other current assets”)

Contingent assets - current	December 31, 2025 3,253 $	December31,2024
		1,945 $

In response to the requirements of the customer contracts, the Company purchased the related materials and paid the related costs to the subcontractors. The costs were clearly identified relating to the contracts, and the costs were expected to be recoverable. The related revenue and costs would be recognised when the contractual performance obligations were completed.

• E. Aggregate amount of the transaction price allocated to construction contracts that are partially or fully unsatisfied as at December 31, 2025 and 2024, amounted to $12,390,120 and $12,251,649, respectively. Management expects that the transaction price allocated to the unsatisfied contracts as of December 31, 2025 and 2024 will be satisfied and recognised as revenue in the next one to two year(s).

• Except for the abovementioned contracts, all other construction contracts are for periods of one year or less. As permitted under IFRS 15, the transaction price allocated to these unsatisfied contracts is not disclosed.

• F. The Company always recognises lifetime expected credit losses (ECLs) for contract assets. Contract assets are recognised as accounts receivable when the invoices are issued. The credit risk of contract assets is the same as the accounts receivable arising from similar contracts; so the allowance for losses on contract assets is measured based on the expected credit loss on accounts receivable. Also, if the credit risk of a contract asset has increased significantly since the original recognition, an allowance for loss on the contract asset should be recognised on a case-by-case basis. The amount of the allowance for loss is measured as the difference between the asset's carrying amount and the present value of estimated future cash flows discounted at the effective interest rate. The movement of the allowance for losses on contract asset for the years ended December 31, 2025 and 2024 was as follows:

Balance at January 1 (Reversal of) provision for impairment ( Balance at December 31	For the years endedDecember31,	For the years endedDecember31,

• iv. The total exchange gain, including realised and unrealised, arising from significant foreign exchange variation on the monetary items held by the Company for the years ended December 31, 2025 and 2024, amounted to $14,254 and $22,098, respectively.

Price risk

• i. The Company’s equity securities, which are exposed to price risk, are the held financial assets at fair value through other comprehensive income. To manage its price risk arising from investments in equity securities, the investment approach is conducted in accordance with the limits set by the Company.

• ii. The Company’s investments in equity securities comprise shares issued by the domestic companies. The prices of equity securities would change due to the change of the future value of investee companies. If the prices of these equity securities had increased/decreased by 1% with all other variables held constant, other components of equity for the years ended December 31, 2025 and 2024 would have increased/decreased by $542 and $500, respectively, as a result of other comprehensive income on equity investments classified as at fair value through other comprehensive income.

Cash flow and fair value interest rate risk

• i. The Company’s interest rate risk arises from long-term and short-term borrowings. Borrowings with variable rates expose the Company to cash flow interest rate risk and the risk is partially offset by cash and cash equivalents held at variable rates. During 2025 and 2024, the Company’s borrowings at variable rate were denominated in NTD and USD.

~60~

• ii. If the borrowing interest rate had increased/decreased by 50 basis point with all other variables held constant, profit, net of tax for the years ended December 31, 2025 and 2024 would have decreased/increased by $789 and $2,105, respectively. The main factor is that changes in interest expense result in floating-rate borrowings.

• iii. The Company did not use any financial instrument to hedge its interest rate risk.

• (b) Credit risk

• i. Credit risk refers to the risk of financial loss to the Company arising from default by the clients or counterparties of financial instruments on the contract obligations. The main factor is that counterparties could not repay in full the contract assets and accounts receivable based on the agreed terms.

• ii. The Company manages its credit risk taking into consideration the entire company’s concern. According to the Company’s credit policy, the Company is responsible for managing and analysing the credit risk for each of the 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 utilisation of credit limits is regularly monitored.

• iii. The Company considers that the default occurs when the contract payments are past due over 365 days.

• iv. The Company adopts the assumptions under IFRS 9, if the contract payments were past due over 30 days based on the terms, there has been a significant increase in credit risk on that instrument since initial recognition.

• v. Information relating to the Company’s credit risk of contract assets, accounts receivable and notes receivable is provided in Notes 6(4) and (18).

(c) Liquidity risk

• i. Cash flow forecasting is performed by Company treasury. Company treasury monitors rolling forecasts of the Company’s liquidity requirements to ensure it has sufficient cash to meet operational needs while maintaining sufficient headroom on its undrawn committed borrowing facilities at all times so that the Company does not breach borrowing limits or covenants (where applicable) on any of its borrowing facilities. Such forecasting takes into consideration the Company’s debt financing plans, covenant compliance, compliance with internal balance sheet ratio targets and, if applicable external regulatory or legal requirements.

• ii. As of December 31, 2025 and 2024, the Company’s undrawn bank borrowing facilities amounted to $5,227,974 and $4,519,264, respectively.

~61~

• iii. The table below analyses the Company’s non-derivative financial liabilities and netsettled or gross-settled derivative financial liabilities into relevant maturity groupings based on the remaining period at the balance sheet date to the contractual maturity date for non-derivative financial liabilities and to the expected maturity date for derivative financial liabilities. The amounts disclosed in the table are the contractual undiscounted cash flows.

Note: Including current portion.

(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:

• 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.

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

~62~

• Level 3: Unobservable inputs for the asset or liability. The fair value of the Company’s investment in equity investment without active market and investment property is included in Level 3.

• B. Financial instruments not measured at fair value

• The carrying amounts of cash and cash equivalents, financial assets at amortised cost, notes receivable, accounts receivable (including related parties), other receivables (including related parties), refundable deposits (recognised as “other non-current assets”), accounts payable (including related parties), other payables, short-term borrowings, long-term borrowings (including current portion) and lease liabilities (including current portion) 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 at December 31, 2025 and 2024 is as follows:

• (a) The related information on the nature of the assets and liabilities is as follows:

----- End of picture text -----

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

• i. 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.

~63~

• ii. 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 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 consolidated balance sheet. The inputs and pricing information used during valuation are carefully assessed and adjusted based on current market conditions.

• D. The following chart is the movement of Level 3 for the years ended December 31, 2025 and 2024:

2024:
Balance at January 1 Acquired during the year Balance at December 31	2025 50,000 $ 4,154 54,154 $	2024
		- $ 50,000
		50,000 $

• E. Finance department is in charge of valuation procedures for fair value measurements being categorised within Level 3, which is to verify independent fair value of financial instruments. Such assessment is to ensure the valuation results are reasonable by applying independent information to make results close to current market conditions, confirming the resource of information is independent, reliable and in line with other resources and represented as the exercisable price, and frequently calibrating valuation model, updating inputs used to the valuation model and making any other necessary adjustments to the fair value.

• F. The following is the qualitative information of significant unobservable inputs and sensitivity analysis of changes in significant unobservable inputs to valuation model used in Level 3 fair value measurement:

Non-derivative equity instrument: Unlisted shares	Fair value at December31,2025 54,154 $	Valuation Significant unobservable technique input Market comparable companies Equity to asset ratio multiple and discount for lack of marketability	Range (weighted average) 1.50~9.21	Relationship of inputs to fairvalue
				The higher the multiple, the higher the fair value; the higher the discount for lack of marketability, the lower the fair value

~64~

Non-derivative equity instrument: Unlisted shares	Fair value at December31,2024 50,000 $	Valuation Significant unobservable technique input Market comparable companies Equity to asset ratio multiple and discount for lack of marketability	Range (weighted average) 2.21~11.71	Relationship of inputs to fairvalue
				The higher the multiple, the higher the fair value; the higher the discount for lack of marketability, the lower the fair value

• G. The Company has carefully assessed the valuation models and assumptions used to measure fair value. However, use of different valuation models or assumptions may result in different measurement. The following is the effect on profit or loss or on other comprehensive income from financial assets and liabilities categorised within Level 3 if the inputs used to valuation models have changed:

December 31, 2025 Recognised in other comprehensive income Input Change Favourable change Unfavourable change Financial assets Equity instrument Equity to asset ratio ±1% $ 542 ($ 542) multiple and discount for lack of marketability December 31, 2024 Recognised in other comprehensive income Input Change Favourable change Unfavourable change Financial assets Equity instrument Equity to asset ratio ±1% $ 500 ($ 500) multiple and discount for lack of marketability
