Independent Auditors’ Review Report (114) Tsai-Sheng-Bao-Zi No. 25001978

To Taiwan Mask Corporation,

Introduction

We have audited the accompanying consolidated balance sheets for the periods starting January 1 and ending September 30, 2025 and 2024, the consolidated statements of comprehensive income for the periods starting July 1 and ending September 30, 2025 and 2024, and starting January 1 and ending September 30, 2025 and 2024, and the consolidated statements of changes in equity and cash flows for the period starting January 1 and ending September 30, 2025 and 2024, as well as the notes to the consolidated financial statements (including the summary of significant accounting policies), for Taiwan Mask Corporation and subsidiaries (collectively referred to as the “Group”). The Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with “Regulations Governing the Preparation of Financial Reports by Securities Issuers” and IAS No. 34, “Interim Financial Reporting” as endorsed by the Financial Supervisory Commission. Our responsibility is to express a conclusion on these consolidated financial statements based on our reviews.

Scope

Except as explained in the following paragraph, we conducted our reviews in accordance with Standards on Review Engagements No. 2410, “Review of Financial Statements” in the Republic of China. The procedures performed when reviewing the consolidated financial statements include inquiries (mainly inquiring personnel responsible for financial and accounting tasks), analytical procedures and other review procedures. The scope of review is obviously smaller than that of audit . Therefore, the accountant may not be able to detect all the significant matters that can be identified through audit, so it is impossible to express an audit opinion.

Basis for qualified opinion

As stated in Note 4(3) of the consolidated financial statements, the financial statements of the same period of some insignificant subsidiaries included in the aforementioned consolidated financial statements have not been reviewed by the CPAs, and the total amount of their assets as of September 30, 2025 and 2024 was NT$2,846,836 thousand and NT$2,891,537 thousand, accounting for 15.60% and 13.12% of the total consolidated assets, respectively; the total amount of their liabilities was NT$2,062,862 thousand and NT$2,108,103 thousand, accounting for 15.17% and 12.23% of the total consolidated liabilities, respectively; the total amount of comprehensive income from July 1 to September 30, 2025 and 2024 was NT$ (87,538) thousand and NT$ (324,336) thousand, and that from January 1 to September 30, 2025 and 2024 was NT$ (405,453) thousand and NT$ (776,939) thousand, accounting for 49.62%, 110.54%, 38.52% and

~4~

15,740.25% the total consolidated comprehensive income, respectively. As stated in Notes 6 (6) to the Consolidated Financial Statements, part of the investment using the equity method is prepared based on the financial statements from each company for the same period not reviewed by an CPA. The balance of investments using the equity method as of September 30, 2025 and 2024 was NT$51,383 thousand and NT$75,489 thousand, accounting for 0.28% and 0.34% of the total consolidated assets, respectively; the share of assets of associates recognized using the equity of such from July 1 to September 30, 2025 and 2024 was NT$(13,380) thousand and NT$(9,138) thousand, and that from January 1 to September 30, 2025 and 2024 was NT$(37,774) thousand and NT$(26,130) thousand, accounting for 7,58%, 3.11%, 3.59% and 529.38% of the consolidated comprehensive income, respectively.

Qualified opinion

According to our results of the review, except for the part described by the basis for qualified opinion that the financial statement of insignificant subsidiaries and part of the investments using the equity method may affect adjustments to the consolidated financial statements upon the CPA’s review, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Group as of September 30, 2025 and 2024, the results of the consolidated financial operations from July 1 to September 30, 2025 and 2024, and that from January 1 to September 30, 2025 and 2024, and the consolidated cash flows from January 1 to September 30, 2025 and 2024, in conformity with the Regulations Governing the Preparation of Financial Statements by Securities Issuers and IAS 34: “interim financial reporting” endorsed and made effective by the Financial Supervisory Commission of the Executive Yuan.

Other matters

As stated in Note 12(4) of the consolidated financial statements, the Group’s debt ratio and current ratio as of September 30, 2025, were 75% and 63%, respectively. The Group has already submitted a sound business plan.

However, the Group did not hold a majority of the Board of Directors’ seats and therefore did not participate in all operational decisions and business policies including strategic decisions (e.g., financing, acquisitions, personnel and dividend policies, etc.) of Advagene Biopharma Co., Ltd. and Weida Hi-Tech Co., Ltd. The Group’s shareholdings alone did not meet the required attendance percentage at shareholders’ meetings, indicating that the Group has no power to direct relevant activities and therefore the Group does not have control over the company and has only significant influence.
The Group sold the shares of Advagene Biopharma Co., Ltd. from January to September 2025, resulting in a decrease in shareholding from 25.62% to 20.20%; a gain on disposal of investments of NT$50,098 was recognized.
In March 2024, the Group acquired 13,500 thousand common shares of TrueLight Corporation through private placement with an investment amount of NT$410,400. As of June 30, 2025, the shareholding ratio was 12.11%, making the Group the single largest shareholder of the company. However, the Group’s shareholding does not reach the statutory attendance percentage of shareholders meetings, indicating that the Group has no actual ability to direct relevant activities. Therefore, it is judged that the Group has no control over the company, and only has significant influence on it.
In April 2024, the Group acquired 6,000 thousand common shares of BKS Tec Corp. through capital increase in cash, with an investment amount of NT$30,000. As of September 30, 2025, the shareholding ratio was 38.91%, making the Group the single largest shareholder of the company. However, the Group did not hold a majority of the Board of Directors’ seats and therefore did not actually participate in the business decisions and operating policies, including strategic decisions (such as financing, acquisitions, personnel and dividend policies) of BKS Tec Corp. The Group’s shareholding alone does not reach the statutory attendance percentage of shareholders meetings, indicating that the Group has no actual ability to direct relevant activities. Therefore it is judged that the Group has no control over the company, and only has significant influence on it.

After using the retained earnings for funding, the remaining surplus will be distributed in the form of dividends, and the distribution steps are shown as follows:

(2) Decide on the financing required for one of the capital budgeting items.
(3) Decide on the amount of the financing to be supported by retained earnings

~52~

(methods such as cash capital increase or corporate bonds and so on can be adopted as support).

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

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 equity instrument price had increased/decreased by 1% with all other variables held constant, net income after tax from equity instruments at fair value through profit or loss for the nine months ended September 30, 2025 and 2024, would have increased/decreased by NT$12,216 and NT$35,677, respectively; other comprehensive income classified as equity investment at fair value through other comprehensive income would have both increased/decreased by NT$0.

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 January 1 to September 30, 2025 and 2024, 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 borrowing interest rate had increased/decreased by 0.25% with all other variables held constant, net income after tax for January 1 to September 30, 2025 and 2024, would have increased/decreased by NT$13,396 and NT$20,754, respectively due to the change in interest expenses as a result of borrowings with

~71~

floating interest rates.

(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

~72~

built according to historical and current data in order to estimate the loss allowance of accounts receivable and notes receivable. The provision matrix for September 30, 2025, December 31, 2024 and September 30, 2024 is shown as follows:

	$ 110,762 2,055 15 ( 6,273) $ 106,559

(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.

~73~

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, and 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 adequate headroom as determined by the aforementioned forecasts. As of September 30, 2025, December 31, 2024 and September 30, 2024, the Group held money market positions of NT$2,108,491, NT$2,325,127 and NT$2,207,773, respectively, which are expected to generate cash flow immediately to manage liquidity risk.
C. The Group’s unutilized borrowings are shown as follows:

Floating rate Short-term credit limits Medium to long- term credit limits Fixed rate Medium to long- term credit limits	September 30, 2025 $ 456,877 25,500 40,000 $ 522,377	December 31, 2024 $ 920,414 - 4,493 $ 924,907	September 30, 2024 $ 281,256 - 8,326 $ 289,582

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. Non-derivative financial liabilities are analyzed based on the remaining period from the balance sheet date to the contract maturity date. The amounts disclosed in the table are the contractual undiscounted cash flows.

(III) Fair value information

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. 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.

~75~

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.
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:

September 30, 2025 Assets Recurring fair value measurements Financial Assets at Fair Value Through Profit or Loss Equity securities 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 September 30, 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	Level 1 $1,829,545	Level 2 $68,200 Level 2 $57,520 $- Level 2 $95,900 $-	Level 3 $138,303 Level 3 $129,721 $19,204 Level 3 $137,135 $12,902	Total $2,036,048

	$-			$ 19,204
	Level 1 $4,226,590			Total $4,459,625
	$-			$ 12,902

~76~

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

Market price	Shares of listed and OTC company Closing price	Open-end funds
		Net Value

(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 was no transfer between Levels 1 and 2 for January 1 to September 30, 2025 and 2024.
The following table shows the changes in Level 3 for January 1 to September 30, 2025 and 2024:

January 1, 2025 Acquisition cost of the period Return of capital by investee company Sold in this period Corporate bonds redeemed in this period Recognized in profit or loss of the period Impact from exchange rate September 30, 2025	Financial instruments $ 110,517 15,000 ( 2,500) ( 2,925) 15,234 3,970 ( 994) $ 138,302

As Image Match Design Inc. was officially listed on the Emerging Stock Market on March 10, 2025, and trading volume in the market has increased steadily, sufficient observable market data has become available. Accordingly, the Group reclassified the fair value measurement of the investment from Level 3 to Level 2 at the end of the month in which the event occurred.
The quantitative information about the significant unobservable input value of the valuation model and the sensitivity analysis of the significant unobservable input value change used in the Level 3 fair value measurements are explained as follows:

The Corporate Group has carefully assessed the valuation models and parameters used to measure fair value. However, use of different valuation models or parameters may result in different measurement. For financial assets or liabilities classified in Level 3, changes in valuation parameters have the following impacts on the income or other comprehensive income of the period:

(IV) Sound Business Plan

As of September 30, 2025, the Group’s financial structure showed a debt ratio of 75% and a current ratio of 63%. In response, the Group has formulated and is actively implementing a sound business plan that addresses capital, operations and governance.

With regard to the fund aspect, the Company organized the first private placement of common stocks in July 2025 with the issuance of 63,370 thousand shares, which were fully subscribed by LUMINOUS RISE INVESTMENT CO., LTD., and a capital amount of NT$1.546 billion was raised and used to repay convertible bonds of NT$1.544 billion in full, achieving a 100% completion rate. Accordingly, the financial leverage and short-term solvency of the Company were effectively improved. In addition, the Company has applied for the public offering of cash capital increase with issuance of new shares with the FSC in October 2025, in order to use the capital raised to repay the bank loans and to reduce the debt ratio at the same time. The application is currently under FSC’s review.

In terms of operations, the Group has streamlined its organizational structure, optimized capacity allocation, strictly controlled raw material procurement and expense spending, and implemented a tiered tracking mechanism for accounts receivable to improve gross margin and accelerate cash collection.

In terms of governance, the Group has implemented an enterprise-wide risk management mechanism and established a quarterly reporting system to regularly update the Board of Directors and the Audit Committee on the execution status. The Group also evaluates market conditions to dispose of non-core assets or reinvestments as needed to supplement cash flow.

The Group expects that the full implementation of the above measures will ensure its ability to continue as a going concern and maintain long-term financial stability.
