Independent Auditors’ Review Report

(2025) Cai-Shen-Bao-Zi No. 25002153 To the Board of Directors of Ruentex Materials Co., Ltd.:

Introduction

We have reviewed the consolidated balance sheets of Ruentex Materials Co., Ltd. and its subsidiaries (hereinafter referred to as “the Group”) as of September 30, 2025 and 2024, the consolidated comprehensive income statements for the three and nine months ended September 30, 2025 and 2024, and the consolidated statements of changes in equity and cash flows for the nine months ended September 30, 2025 and 2024, and the notes to the consolidated financial report(including a summary of significant accounting policies). It is the responsibility of the management to prepare the consolidated financial statements with fair presentation in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and IAS 34 "Interim Financial Reporting" endorsed and issued by the Financial Supervisory Commission. It is our responsibility to draw a conclusion on the consolidated financial statements based on the review results.

Scope of Review

We conducted the review in accordance with the R.O.C. Standards on Review Engagements 2410 "Reviews of Financial Statements." The procedures executed in reviewing the consolidated financial statements include inquiry (mainly with the person in charge of financial and accounting affairs), analytical procedures, and other review procedures. The scope of a review is significantly smaller than the scope of an audit. We therefore are unable to express an audit opinion since we may not able to identify all the significant matters that can be identified by an audit.

Conclusion

Based on our reviews, nothing has come to our attention that causes us to believe that the accompanying consolidated financial statements do not present fairly, in all material respects, the consolidated financial position of the Group as of September 30, 2025 and 2024, consolidated financial performance for the three and nine months ended September 30, 2025 and 2024, and consolidated cash flows for the nine months ended September 30, 2025 and 2024, in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Accounting Standard 34 “Interim Financial Reporting,” endorsed and issued into effect by the Financial Supervisory Commission of the Republic of China.

As of December 31, 2024, investments accounted for using the equity method in Teh Hsin were valued based on financial statements audited by the independent auditor.
(4) On September 20, 2024, the Board of Directors of the Company resolved to acquire equity interest in Teh Hsin. A share purchase agreement was entered into with a nonrelated party on September 26, 2024, for the purchase of 14,969,837 shares at NT$104.5 per share, totaling NT$1,564,348. The acquired shares represent a 35% equity interest. The share transfer registration was completed on November 15, 2024.
(5) The Group holds a 35% equity interest in Teh Hsin and is its single largest shareholder. However, based on the past shareholders' meeting attendance records, it is evident that other shareholders actively participate in Teh Hsin’s decision-making processes. Among the nine seats on Teh Hsin’s Board of Directors, the Group holds only three. This indicates that the Group does not have the practical ability to direct the relevant activities of Teh Hsin. Accordingly, the Group has determined that it does not have control over Teh Hsin, but instead has significant influence.

The Company owns the mine operation rights at Yilan Lankan Mine (Tai-Ji-Cai-Zi No. 5569 Mine Operation Right) and Hualien Huahsin Mine (Tai-Ji-Cai-Zi No. 5345 Marble Mine Operation Right) which will expire on June 18, 2032 and July 1, 2025, respectively. In addition, the Company has submitted an extension application for Hualien Huahsin Mine, which is currently under review. At present, the limestone quarrying in the original mining area has nearly been exhausted and an application has been made to the Bureau of Mines, Ministry of Economic Affairs, in accordance with Article 43 of the Mining Act for an extension of the mining area within the original mine operation rights (Expansion).

On September 15, 2020, the above-mentioned application for the Yilan Lankan Mine Expansion received the Administrative Disposition Jin Shou Wu Zi No. 10920107100 from the Ministry of Economic Affairs, which stated, “Because the public land authority (i.e. the Luodong District Office of the Forestry Bureau of the Council of Agriculture, Executive Yuan) has indicated that the approval of mineral land is denied because it does not meet the requirements of No. 13 of the Regulations for Conservation Forest Managements; therefore, the application is rejected in accordance with Article 43 of the Mining Act.” The Company filed a petition in accordance with the law on October 6, 2020 due to dissatisfaction with the administrative sanction imposed by the authority; however, the petition was rejected by the Executive Yuan, referencing YuanTai-Su-Zi No. 1100178798 dated July 8, 2021. The material changes from the adverse impact on the Company’s assets due to administrative authorities’ fact determination and application of laws had led to signs of impairment of the Company’s assets in accordance with the IAS 36. The property, plants, and equipment of NT$66,151 and intangible assets of NT$73,212 related to the Yilan Lankan Mine, totaling NT$139,363, were recognized in impairment losses in June 2021.

However, to ensure the equity and efficiency of the Company's assets, if the mining land for mining sources legally held can be expanded and continued to be mined, it will make a reasonable contribution to the Company's future profits. The Yilan Lankan Stone Mine expansion case was filed with The High Administrative Court on September 9, 2021, but the administrative lawsuit was dismissed on February 29, 2024 by the Taipei High Administrative

~31~

Court judgment year 2021 Su-Zi No. 1062. The Company has already make a provision for impairment loss. Hence, there is no material impact on the Company’s finance or business of the judgment results, and an appeal has been filed to the Supreme Administrative Court in March 2024, and the litigation is ongoing.

The mining and transportation method for the Hualien Huahsin Mine expansion application involved borrowing another entity’s road. However, because consent to pass through the adjacent mines was not obtained, the Company took the initiative to withdraw the application and will file a new application after re-planning. As of November 10, 2025, the relevant planning is still in progress, and the application procedure has not yet been completed.

~34~

to the subsequent service years of employees who elected to continue under the Labor Standards Act after its implementation. It also applies to all employed foreign midlevel skilled workers. 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 Group contributes an amount equal to 2% of the employees’ monthly salaries and wages each month to the retirement fund deposited with Bank of Taiwan, the trustee, under the name of the independent retirement fund committee. In addition, the Group assesses the balance in the aforementioned labor pension reserve account by the end of December 31, every year. If the account balance is insufficient to pay the pension calculated by the aforementioned method, the Group will make contributions to employees expected to be qualified for retirement next year to cover the deficit by next March.

(I) Capital management

The Group’s objectives when managing capital are to safeguard the company’s ability to continue as a going concern in order to provide returns for shareholders and to maintain an optimal capital structure to reduce the cost of capital. In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid to shareholders, return share capital to shareholders, issue new shares or sell assets in order to adjust to reach the most suitable capital structure. The Group uses the debt-to-capital ratio to monitor its capital, and such ratio is calculated by dividing the net debt by the total capital. The net liabilities is equal to total borrowings (including “current and non-current borrowings” on the consolidated financial statements) deducting cash and cash equivalents. Total capital is the “equity” stated on the consolidated balance sheet plus net liabilities.

The Group’s debt ratios as of September 30, 2025, December 31, 2024, and September 30, 2024, were as follows:

A. The Group’s risk management’s objective is to manage currency exchange risk, interest risk, credit risk, and liquidity risk regarding operating activities. To reduce relevant financial risks, the Group is devoted to identifying, evaluating, and circumventing market uncertainties to mitigate the potential negative impacts on the company’s financial performance due to market movements.
B. The Group’s businesses involve some non-functional currency operations. The information on assets and liabilities denominated in foreign currencies whose values would be affected by exchange rate fluctuations is as follow:

	September 30,2025	September 30,2025	September 30,2025	September 30,2025

$ 17 10 106	31.65 31.65 35.38	$ 538 317 3,750	1% 1% 1%	$ 5 3 38

C. Foreign exchange risk has a significant impact on the Group. The foreign exchange gains or losses (including realized and unrealized) on monetary items recognized were a gain of NT$36, a loss of NT$8, a loss of NT$29, and a gain of NT$63 for the three and nine months ended September 30, 2025 and 2024, respectively.

Price risk

A. The Group’s equity instruments exposed to price risk were the financial assets at fair value through other comprehensive income. To manage its price risk arising from investments in equity securities, the Group diversifies its portfolio. Diversification of the portfolio is done in accordance with the limits set by the Group.
B. The Group mainly invests in domestic or foreign equity instruments. The prices of equity instruments is affected by the uncertainty of the future value of investment

~64~

subject matters. If the prices of these equity instruments had increased/decreased by 1% with all other variables held constant, other comprehensive income due to classification to gains or losses of equity investments at fair value through other comprehensive income for the nine months ended on September 30, 2025 and 2024, would have increased/decreased by NT$5,169 and NT$7,732, respectively.

Cash flow and fair value interest rate risk

A. The Group’s interest rate risk arises from short- and long-term borrowings with floating interest rates that expose the Group to cash flow interest rate risk. For the nine months ended September 30, 2025 and 2024, the Group’s borrowings issued at variable rates were mostly denominated in the New Taiwan Dollar.
B. The borrowing of the Group was measured at amortized cost, and re-pricing was performed according to the annual interest rate specified in the contract. Therefore, the Group is exposed to the risk of future market interest rate changes.
C. If interest rates on borrowings had been 0.1% higher or lower with all other variables held constant, profit after income tax for the nine months ended September 30, 2025 and 2024, would have decreased/increased by NT$2,784 and NT$1,830, respectively, due to change of interest expenses of borrowings at the variable interest rate.
(2) Credit risk
A. Credit risk refers to the risk of financial loss to the Group arising from default by clients or transaction counterparties of financial instruments on the contract obligations. Such risk is mainly due to the counterparties inability to repay the contract assets and accounts receivable according to the payment terms, and it is classified as contract cash flow at amortized cost.
B. The Group established management of credit risk from the Group’s perspective. According to the internally specified credit extension policy, before each operating entity and each new customer establish the terms for payment and goods delivery, it is necessary to perform management and credit risk analysis. The internal risk control considers the financial position, past experience and other factors in order to assess the credit quality of customers. 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 adopts IFRS 9 to provide preliminary assumption, and when the payment specified according to the contract term has exceeded 90 days, breach of contract is deemed to have occurred.

~65~

D. The Group uses IFRS 9 to provide the following assumptions, to determine if the credit risks of the financial instrument significantly increased since the initial recognition.

When the contractual payments are overdue from the payment terms for more than 30 days, it is deemed that the credit risks of the financial instrument significantly have increased since the initial recognition.

E. The Group classifies the accounts payable of customers according to the characteristics of customer type, and adopts the simplified method to use the loss rate method as the basis for estimating the expected credit loss.
F. After the collection procedures, the amount of financial assets that cannot be reasonably estimated will be written-off. However, the Group will continue to pursue the legal right of recourse to protect its claims.
G. The Group utilized the forecasting capabilities of the Taiwan Institute of Economic Research report to adjust historical and timely information in order to assess the likelihood of default and estimate impairment provisions for accounts receivable (including related parties) and contract assets (including related parties). As of September 30, 2025, December 31, 2024, and September 30, 2024, the loss rate methodology is as follows:

methodology is as follows:
September 30, 2025 Expected loss Total carrying amount Allowance for losses December 31, 2024 Expected loss Total carrying amount Allowance for losses September 30, 2024 Expected loss Total carrying amount Allowance for losses		Group1	Group2	Total
		0.01%~0.03% $ 1,096,399 $ 88 Group1	0.86%~100% $ 309,108	$ 1,405,507 $ 9,574 Total
			$ 9,486
			Group2
	0.01%~0.03% $ 1,239,921 $ 97 Group1		0.63%~100% $ 309,040	$ 1,548,961 $ 10,535 Total
			$ 10,438
			Group2
		0.01%~0.03% $ 1,182,756 $ 99	0.63%~100% $ 309,884	$ 1,492,640 $ 13,481
			$ 13,382

~66~

Group 1: Sales counterparty established for 10 years and more, or accounts receivables arising from transactions with related parties and contracts for public construction or to debtors who have high probability of performing the payment financially.
Group 2: Sales counterparty established for less than 10 years, or those who have general payment performance ability.
H. The accounts receivable allowance loss change table under the simplified approach of the Group is as follows:

January 1 Reversal of impairment loss Provision of impairment loss September 30		2025 Accounts receivable $ 10,535 ( 961) - $ 9,574		2024
				Accounts receivable
				$ 7,144 - 6,337 $ 13,481

I. The financial assets measured by the amortized cost accounted for by the Group are demand deposit with original maturity date for more than three months. Because the cooperating financial institutions’ credit ratings are good, and the Company has conducted transactions with many financial institutions to diversify the credit risk, the probability of default is expected to be very low.
(3) Liquidity risk
A. Cash flow forecasting is performed by each of the operating entities of the Group and aggregated by the Finance Department. The Department also monitors the projections for the Group’s need for funds to ensure that there is sufficient funding to support operating requirements.
B. For the remaining cash held by each of the operating entities, when it exceeds the management needs of operating capital, it then invests the remaining capital in a saving deposit with interest, time deposit, or equivalent cash - repurchase agreements, etc. The instruments selected have appropriate maturity date or sufficient liquidity in order to cope with the aforementioned forecasts and to provide sufficient movement level.

C. Details of the loan credit not yet drawn down by the Group are as follows:

Due within one year Due longer than one year	September 30, 2025	December 31, 2024 $ 1,211,260 700,000 $ 1,911,260	September 30, 2024 $ 1,301,260 800,000 $ 2,101,260
	$ 1,029,310 1,116,000 $ 2,145,310

(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 listed stocks is included.
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.
Financial instruments other than those measured at fair value

The carrying amount of the Group’s cash and cash equivalents and the financial instruments measured at amortized cost, including notes receivable (including related parties), accounts receivable (including related parties), other receivables (including related parties), other financial assets, guarantee deposits paid, short-term borrowings, short-term notes payable, notes payable (including related parties), accounts payable (including related parties), other payables (including related parties), other long-term borrowings, and guarantee deposits received are approximate to their fair values.

The related information of financial and non-financial instruments measured at fair value by level on the basis of the natures, characteristic and risk, and fair value of the assets is as follows:

Level 1	Level 2	Level 3	Total $ 516,882
$ 516,882	$-	$-
Level 1	Level 2	Level 3	Total $ 717,099
$ 717,099	$-	$-

September 30, 2024 Level 1 Level 2 Level 3 Total Assets Recurring fair value Financial Assets at fair value through other comprehensive income acquired Equity securities - - $ 773,216 $ $ $ 773,216

The Group’s financial instruments are traded in active markets, their fair value is measured based on the market quotation at the end of the balance sheet date. The market is deemed to be an active market when the quotation can be obtained instantly and regularly from the stock exchange, dealer, broker, industry, rating agencies, and regulatory body, and that the quotation represents the actual and regular market transactions conducted under the basis of a normal transaction. The market price of the financial assets held by the Group is the closing market price. These instruments belong to Level 1. Level 1 instruments are mainly equity instruments. Their classification is financial assets at fair value through other comprehensive income.
There was no transfer between the Level 1 and the Level 2 fair values for the nine months ended September 30, 2025 and 2024.
