Subject:

To announce the differences between consolidated financial statements for the nine months ended September 30, 2025 under Taiwan-IFRSs and that under IFRSs

To which item it meets – article 4 paragraph xx:47 (Form 1)

Date of events: 2025/11/10

Contents:

1.	Date of occurrence of the event:

2025/11/10

2.	Year/Quarter of the financial report:

The third quarter of 2025

3.	Accounting principles applied for securities listed domestically:

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 (“Taiwan-IFRSs”)

4.	Inconsistent items/amounts in financial reports for securities listed domestically:

Under Taiwan-IFRSs, Chunghwa Telecom Co., Ltd. and its subsidiaries (or the “Company”) reported consolidated net income of NT$9,854,849 thousand and NT$30,655,286 thousand, consolidated net income attributable to stockholders of the parent of NT$9,440,098 thousand and NT$29,406,456 thousand, and basic earnings per share of NT$1.22 and NT$3.79 for the three months and nine months ended September 30, 2025, respectively. The Company also reported total consolidated assets of NT$513,095,556 thousand, total consolidated liabilities of NT$122,665,684 thousand, and total consolidated equity of NT$390,429,872 thousand as of September 30, 2025.

- 1 -

5.	Accounting principles applied for securities issued overseas:

IAS 34 “Interim Financial Reporting” as issued by the International Accounting Standard Board (“IFRSs”)

6.	Inconsistent items/ amounts (securities issued overseas):

Under IFRSs, the Company reported consolidated net income of NT$9,336 million and NT$31,153 million, consolidated net income attributable to stockholders of the parent of NT$8,941 million and NT$29,896 million, and basic earnings per share of NT$1.15 and NT$3.85 for the three months and nine months ended September 30, 2025, respectively. The Company also reported total consolidated assets of NT$512,903 million, total consolidated liabilities of NT$124,268 million, and total consolidated equity of NT$388,635 million as of September 30, 2025.

7.	Inconsistent items/amounts in financial information for securities issued overseas:

The differences between consolidated net income under Taiwan-IFRSs and that under IFRSs followed by the Company mainly come from the timing of the recognition of income tax on unappropriated earnings. In addition, prior to incorporation, the Company was subject to the laws and regulations applicable to state-owned enterprises in Taiwan which differed from the generally accepted accounting principles as applicable to commercial companies. As such, revenue from providing fixed line connection service and selling prepaid phone cards was recognized at the time the service was performed or the card was sold by the Company. Upon incorporation, net assets greater than the capital stock were credited as additional paid-in-capital and part of the additional paid-in-capital was from the unearned revenues generated from connection fees and prepaid cards as of the date of incorporation. Under IFRSs, revenue from connection fees and prepaid phone cards was deferred at the time of the service performed or sale and recognized as revenue over time as the service is continuously performed or as consumed. This reclassification from additional paid-in capital to retained earnings did not affect total equity.

8.	Any other matters that need to be specified:

Chunghwa Telecom’s earnings distribution and stockholders’ equity matters are in accordance with Taiwan-IFRSs.

Chunghwa Telecom Co., Ltd. and Subsidiaries

Consolidated Financial Statements for the

Nine Months Ended September 30, 2025 and 2024 and

Independent Auditors’ Review Report

INDEPENDENT AUDITORS’ REVIEW REPORT

PWCR25002096

To the Board of Directors and Stockholders of Chunghwa Telecom Co., Ltd.

Introduction

We have reviewed the accompanying consolidated balance sheets of Chunghwa Telecom Co., Ltd. and its subsidiaries (the “Company”) as of September 30, 2025 and 2024, and the related consolidated statements of comprehensive income for the three-month and nine-month periods then ended, as well as the consolidated statements of changes in equity and of cash flows for the nine-month periods then ended, and notes to the consolidated financial statements, including a summary of material accounting policy information. Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Accounting Standard 34, “Interim Financial Reporting”, that came into effect as endorsed by the Financial Supervisory Commission. Our responsibility is to express a conclusion on these consolidated financial statements based on our reviews.

Scope of Review

We conducted our reviews in accordance with the Standards on Review Engagements 2410, “Review of Interim Financial Information Performed by the Independent Auditor of the Entity” of the Republic of China. A review of consolidated financial statements consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

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

Notice to Readers

The accompanying consolidated financial statements are not intended to present the financial position and results of operations and cash flows in accordance with accounting principles generally accepted in countries and jurisdictions other than the Republic of China. The standards, procedures and practices in the Republic of China governing the audit of such financial statements may differ from those generally accepted in countries and jurisdictions other than the Republic of China. Accordingly, the accompanying consolidated financial statements and independent auditors’ review report are not intended for use by those who are not informed about the accounting principles or auditing standards generally accepted in the Republic of China, and their applications in practice. As the financial statements are the responsibility of the management, PricewaterhouseCoopers cannot accept any liability for the use of, or reliance on, the English translation or for any errors or misunderstandings that may derive from the translation.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NINE MONTHS ENDED SEPTEMBER 30, 2025 AND 2024

(In Thousands of New Taiwan Dollars, Unless Stated Otherwise)

GENERAL

Chunghwa Telecom Co., Ltd. (“Chunghwa”; Chunghwa together with its subsidiaries are hereinafter referred to collectively as the “Company”.) was incorporated on July 1, 1996 in the Republic of China (“ROC”). Chunghwa is a company limited by shares and, prior to August 2000, was wholly owned by the Ministry of Transportation and Communications (“MOTC”). Prior to July 1, 1996, the current operations of Chunghwa were carried out under the Directorate General of Telecommunications (“DGT”). The DGT was established by the MOTC in June 1943 to take primary responsibility in the development of telecommunications infrastructure and to formulate policies related to telecommunications. On July 1, 1996, the telecom operations of the DGT were spun-off as Chunghwa which continues to carry out the business and the DGT continues to be the industry regulator.

Effective August 12, 2005, the MOTC completed the process of privatizing Chunghwa by reducing the government ownership to below 50% in various stages. In July 2000, Chunghwa received approval from the Securities and Futures Commission (the “SFC”) for a domestic initial public offering and its common stocks were listed and traded on the Taiwan Stock Exchange (the “TWSE”) on October 27, 2000. Certain of Chunghwa’s common stocks were sold, in connection with the foregoing privatization plan, in domestic public offerings at various dates from August 2000 to July 2003. Certain of Chunghwa’s common stocks were also sold in an international offering of securities in the form of American Depository Shares (“ADS”) on July 17, 2003 and were listed and traded on the New York Stock Exchange (the “NYSE”). The MOTC sold common stocks of Chunghwa by auction in the ROC on August 9, 2005 and completed the second international offering on August 10, 2005. Upon completion of the share transfers associated with these offerings on August 12, 2005, the MOTC owned less than 50% of the outstanding shares of Chunghwa and completed the privatization plan.

The consolidated financial statements are presented in Chunghwa’s functional currency, New Taiwan dollars.

Chunghwa continues to control more than half of seats of the Board of Directors of SENAO through the support of large beneficial stockholders. As a result, the Company treated SENAO as a subsidiary.

CHIEF issued new shares in December 2024 and March 2025 as its employees exercised options. Therefore, the Company’s ownership interest in CHIEF decreased to 58.57% and 58.56% as of December 31, 2024 and September 30, 2025, respectively.

Chunghwa controlled more than half of seats of the Board of Directors of CHST as of December 31, 2024; therefore, the Company treated CHST as a subsidiary. Chunghwa no longer had more than half of seats of the Board of Directors of CHST since January 2025. As a result, the Company lost control over CHST and recognized CHST as an investment in associate. Please refer to Note 14(c) for details.

CLPT issued new shares in July 2024 as its employees exercised options. Therefore, the Company’s ownership interest in CLPT decreased to 69.87% as of December 31, 2024.

CHTSC conducted its initial public offering through public underwriting in September 2025, and Chunghwa did not participate in the capital increase of CHTSC in accordance with applicable regulations. CHTSC issued new shares in January 2024, March 2024, December 2024, February 2025, May 2025 and August 2025 as its employees exercised options. In addition, Chunghwa disposed of some shares of CHTSC in August 2024 before CHTSC traded its shares on the emerging stock market according to the local requirements. Therefore, the Company’s ownership interest in CHTSC decreased to 63.49%, 63.45% and 56.69% as of September 30, 2024, December 31, 2024 and September 30, 2025, respectively.

Chunghwa disposed of some shares of IISI in August 2024 before IISI traded its shares on the emerging stock market according to the local requirements.

Chunghwa invested and established CHTEU in July 2024. Chunghwa obtained 100% ownership interest of CHTEU.

CHIEF has more than half of seats of the Board of Directors of SCT according to the mutual agreements among stockholders and gained control over SCT; hence, SCT is deemed as a subsidiary of the Company.

Though the Company’s ownership interest in CHPT is less than 50%, the management considered the absolute and relative size of ownership interest, and the dispersion of shares owned by the other stockholders and concluded that the Company has a sufficiently dominant voting interest to direct the relevant activities; hence, CHPT is deemed as a subsidiary of the Company.

CHTS established CHTM in June 2025 and obtained 100% ownership interest in CHTM. The investment capital was remitted in October 2025.

The following diagram presented information regarding the relationship and percentages of ownership interests between Chunghwa and its subsidiaries as of September 30, 2025.

Other Material Accounting Policies

Defined benefit retirement benefits

Pension cost for an interim period is calculated on a year-to-date basis by using the actuarially determined pension cost rate at the end of the prior financial year, adjusted for significant market fluctuations since that time and for other significant one-off events.

Taxation

Income tax expense represents the sum of the tax currently payable and deferred tax. Income taxes for interim period are assessed on an annual basis and calculated by applying to an interim period’s pre-tax income the tax rate that would be applicable to expected total annual earnings.

The measurement of deferred tax assets and liabilities reflects the tax consequences that would follow from the manner in which the Company expects to recover or settle the carrying amount of its assets and liabilities at balance sheet date.

- 13 -

Loss of control of subsidiaries

When the Company loses control of a subsidiary, a gain or loss is recognized in profit or loss and is calculated as the difference between (a) the aggregate of the fair value of the consideration received and any investment retained in the former subsidiary at its fair value at the date when control is lost and (b) the assets (including any goodwill) and liabilities and any non-controlling interests of the former subsidiary at their carrying amounts at the date when control is lost. The Company accounts for all amounts recognized in other comprehensive income in relation to that subsidiary on the same basis as would be required had the Company directly disposed of the related assets or liabilities.

The fair value of any investment retained in the former subsidiary at the date when control is lost is regarded as the cost on initial recognition of an investment in an associate.

The main credit terms range from 30 to 90 days.

The Company serves a large consumer base for telecommunications business; therefore, the concentration of credit risk is limited. When having transactions with customers, the Company considers the record of arrears in the past. In addition, the Company may also collect some telecommunication charges in advance to reduce the payment arrears in subsequent periods.

The Company adopted a policy of dealing with counterparties with certain credit ratings for project business and to obtain collateral where necessary to mitigate the risk of loss arising from defaults. Credit rating information is provided by independent rating agencies where available and, if such credit rating information is not available, the Company uses other publicly available financial information and its own historical transaction experience to rate its major customers. The Company continues to monitor the credit exposure and credit ratings of its counterparties and spread the credit risk amongst qualified counterparties.

In order to mitigate credit risk, the management of the Company has delegated a team responsible for determining credit limits, credit approvals and other monitoring procedures to ensure the recoverability of receivables. In addition, the Company reviews the recoverable amount of receivables at balance sheet dates to ensure that adequate allowance is provided for possible irrecoverable amounts. In this regard, the management believes the Company’s credit risk could be reasonably reduced.

The Company applies the simplified approach to recognize expected credit losses prescribed by IFRS 9, which permits the use of lifetime expected loss provision for receivables. The expected credit losses on receivables are estimated using a provision matrix by reference to past default experience of the customers and an analysis of the customers’ current financial positions, as well as the forward-looking indicators such as macroeconomic business indicators.

When there is evidence indicating that the counterparty is in evasion, bankruptcy, deregistration or the accounts receivable are over two years past due and the recoverable amount cannot be reasonable estimated, the Company writes off the trade notes and accounts receivable. For accounts receivable that have been written off, the Company continues to engage in enforcement activity to attempt to recover the receivables due. Where recoveries are made, these are recognized in profit or loss.

Except for receivables arising from telecommunications business and project business, the Company’s remaining accounts receivable are insignificant. Therefore, only Chunghwa’s provision matrix arising from telecommunications business and project business is disclosed below:

Loss of control of subsidiaries

Chunghwa no longer had more than half of seats of the Board of Directors of CHST since January 2025. As a result, the Company lost control over CHST and recognized CHST as an investment in associate.

The disposal gain was included in other gains or losses in the consolidated statements of comprehensive income.

The Company mainly enters into lease-in agreements of land and buildings for handsets base stations located throughout Taiwan with lease terms ranging from 1 to 20 years. The lease agreements do not contain bargain purchase options to acquire the assets at the expiration of the respective leases. For majority of the lease-in agreements on handsets base station, the Company has the right to terminate the agreement prior to the expiration date if the Company is unable to build the required telecommunication equipment, either due to legal restrictions, controversial events, or other events.

Other financial assets—noncurrent was Piping Fund. As part of the government’s effort to upgrade the existing telecommunications infrastructure, Chunghwa and other public utility companies were required by the ROC government to contribute to a Piping Fund administered by the Taipei City Government. This fund was used to finance various telecommunications infrastructure projects. Net assets of this fund will be returned proportionately after the project is completed.

21.	HEDGING FINANCIAL INSTRUMENTS

Chunghwa’s hedge strategy is to enter into forward exchange contracts—buy to avoid its foreign currency exposure to certain foreign currency denominated equipment payments in the following six months. In addition, Chunghwa’s management considers the market condition to determine the hedge ratio and enters into forward exchange contracts with the banks to avoid the foreign currency risk.

Chunghwa signed equipment purchase contracts with suppliers and entered into forward exchange contracts to avoid foreign currency risk exposure to Euro-denominated purchase commitments. Those forward exchange contracts were designated as cash flow hedges. When forecast purchases actually take place, basis adjustments are made to the initial carrying amounts of hedged items.

For the hedges of highly probable forecast sales and purchases, as the critical terms (i.e. the notional amount, life and underlying) of the forward foreign exchange contracts and their corresponding hedged items are the same, the Company performs a qualitative assessment of effectiveness and it is expected that the value of the forward contracts and the value of the corresponding hedged items will systematically change in opposite direction in response to movements in the underlying exchange rates.

The main source of hedge ineffectiveness in these hedging relationships is the effect of credit risks of the Company and the counterparty on the fair value of the forward exchange contracts. Such credit risks do not impact the fair value of the hedged item attributable to changes in foreign exchange rates. No other sources of ineffectiveness emerged from these hedging relationships.

Additional paid-in capital from share premium, donated capital and the difference between the consideration received or paid and the carrying amount of the subsidiaries’ net assets during actual disposal or acquisition may be utilized to offset deficits. Furthermore, when Chunghwa has no deficit, it may be distributed in cash or capitalized, which however is limited to a certain percentage of Chunghwa’s paid-in capital except the additional paid-in capital arising from unclaimed dividend can only be utilized to offset deficits.

The additional paid-in capital from movements of paid-in capital arising from changes in equities of subsidiaries may only be utilized to offset deficits.

Among additional paid-in capital from movements of investments in associates and joint ventures accounted for using equity method, the portion arising from the difference between the consideration received or paid and the carrying amount of the subsidiaries’ net assets during actual disposal or acquisition may be utilized to offset deficits; furthermore, when the Company has no deficit, it may be distributed in cash or capitalized. However, other additional paid-in capital recognized in proportion of share ownership may only be utilized to offset deficits.

Retained earnings and dividends policy

In accordance with the Chunghwa’s Articles of Incorporation, Chunghwa must pay all outstanding taxes, offset deficits in prior years and set aside a legal reserve equal to 10% of its net income before distributing a dividend or making any other distribution to stockholders, except when the accumulated amount of such legal reserve equals to Chunghwa’s total issued capital, and depending on its business needs or requirements, may also set aside or reverse special reserves. No less than 50% of the remaining earnings comprising remaining balance of net income, if any, plus cumulative undistributed earnings shall be distributed as stockholders’ dividends, of which cash dividends to be distributed shall not be less than 50% of the total amount of dividends to be distributed. If cash dividend to be distributed is less than $0.10 per share, such cash dividend shall be distributed in the form of common stocks.

The Company should appropriate a special reserve when the net amount of other equity items is negative at the end of reporting period upon the earnings distribution. Distributions can be made out of any subsequent reversal of the debit to other equity items.

The appropriation for legal reserve shall be made until the accumulated reserve equals the aggregate par value of the outstanding capital stock of Chunghwa. This reserve can only be used to offset a deficit, or, when the legal reserve has exceeded 25% of Chunghwa’s paid-in capital, the excess may be transferred to capital or distributed in cash.

The changes in the contract asset and the contract liability balances primarily result from the timing difference between the satisfaction of performance obligations and the payments collected from customers.

The Company applies the simplified approach to recognize expected credit losses prescribed by IFRS 9, which permits the use of lifetime expected loss provision for receivables. Contract assets will be reclassified to trade receivables when the corresponding invoice is billed to the client. Contract assets have substantially the same risk characteristics as the trade receivables of the same types of contracts. Therefore, the Company concluded that the expected loss rates for trade receivables can be applied to the contract assets.

Incremental costs of obtaining contracts

Current
Incremental costs of obtaining contracts	$	338,581	$	339,172	$	339,055

Noncurrent
Incremental costs of obtaining contracts	$	1,133,181	$	1,221,652	$	1,125,205

The Company considered the past experience and the default clauses in the telecommunications service contracts and believes the commissions and equipment subsidies paid for obtaining such contracts are expected to be recoverable; therefore, such costs were capitalized. The Company also believes the commissions paid for obtaining real estate sale contracts are expected to be recoverable; therefore, such costs were capitalized. Amortization expenses for the three months and nine months ended September 30, 2025 were $237,556 thousand and $709,247 thousand, respectively. Amortization expenses for the three months and nine months ended September 30, 2024 were $234,292 thousand and $670,972 thousand, respectively.

34.	SHARE-BASED PAYMENT ARRANGEMENT

CHIEF share-based compensation plan (“CHIEF Plan”) described as follows:

The Board of Directors of CHIEF resolved to issue 200 stock options on November 13, 2020. Each option is eligible to subscribe for one thousand common stocks when exercisable and the exercise price is $206.00 per share. The options are granted to specific employees that meet the vesting conditions. The CHIEF Plan has an exercise price adjustment formula upon the changes in common stocks or distribution of cash dividends. The options of the CHIEF Plan are valid for five years and the graded vesting schedule will vest two years after the grant date.

CHIEF did not recognize any compensation costs for stock options for the nine months ended September 30, 2025. The compensation costs for stock options for the three months and nine months ended September 30, 2024 were $816 thousand and $2,448 thousand, respectively.

CHIEF modified the plan terms of stock options granted on November 13, 2020 in July 2024; therefore, the exercise price changed from $171.70 to $166.50 per share. The modification did not cause any incremental fair value granted.

Information about CHIEF’s outstanding stock options for the nine months ended September 30, 2025 and 2024 was as follows:


	Nine Months Ended September 30, 2025					Nine Months Ended September 30, 2024
	Granted on November 13, 2020					Granted on November 13, 2020
	Number of Options			Weighted Average Exercise Price (NT$)		Number of Options		Weighted Average Exercise Price (NT$)

Options exercisable at end of the period		—			—		—		—

Weighted average remaining contractual life (years)		—					1.12

- 56 -

CHIEF used the fair value method to evaluate the options using the Black-Scholes model and binomial option pricing model and the related assumptions and the fair value of the options were as follows:


	Stock Options Granted on November 13, 2020
Grant-date share price (NT$)	$	356.00
Exercise price (NT$)	$	206.00
Dividend yield		—
Risk-free interest rate		0.18	%
Expected life		5 years
Expected volatility		34.61	%
Weighted average fair value of grants (NT$)	$	173,893

The expected volatility for the options granted in 2020 was based on CHIEF’s average annualized historical share price volatility from June 5, 2018, CHIEF’s listing date on Taipei Exchange, to the grant date.

New shares reserved for subscription by employees under capital increase of CHTSC

On June 25, 2025, the Board of Directors of CHTSC approved the capital increase to issue 3,683 thousand shares and simultaneously reserved 552 thousand shares, representing 15% of the total issuance, for subscription by employees. Furthermore, when the employees did not fully subscribe or discarded their rights to subscribe shares, the Board of Directors of CHTSC authorized the chairman of the Board of Directors to contact specific people or group to subscribe.

The aforementioned options granted to employees are accounted for and measured at fair value of the grant date in accordance with IFRS 2 “Share-based Payment”. The fair value of CHTSC’s options granted to employees was $1.03 per share. The compensation costs for stock options for the three months and nine months ended September 30, 2025 were both $569 thousand.

CHTSC used the fair value method to evaluate the options granted to employees on August 20, 2025 using the Black-Scholes model and the related assumptions and the fair value of the options were as follows:


	Stock Options Granted on August 20, 2025
Grant-date share price (NT$)	$	216.96
Exercise price (NT$)	$	238.00
Dividend yield		—
Risk-free interest rate		0.97	%
Expected life		0.038 years
Expected volatility		39.95	%
Weighted average fair value of grants (NT$)	$	1.03

Expected life		5 years			5 years
Expected volatility		47.35	%		42.41	%
Weighted average fair value of grants (NT$)	$	3,350		$	2,470

Expected volatility was based on the average annualized historical share price volatility of CHTSC’s comparable companies before the grant date.

d.	CLPT share-based compensation plan (“CLPT Plan”) described as follows:

The Board of Directors of CLPT resolved to issue 690, 600 and 755 stock options on February 26, 2021, May 31, 2022 and September 26, 2023, respectively. Each option is eligible to subscribe for one thousand common stocks when exercisable and the exercise prices are all $16.87 per share. The options are granted to specific employees that meet the vesting conditions. The CLPT Plan has an exercise price adjustment formula upon the changes in common stocks or distribution of cash dividends. The options of the CLPT Plan are valid for four years and the graded vesting schedule will vest two years after the grant date.

The compensation costs for stock options for the three months ended September 30, 2025 and 2024 were $826 thousand and $1,143 thousand, respectively. The compensation costs for stock options for the nine months ended September 30, 2025 and 2024 were $3,063 thousand and $3,751 thousand, respectively.

- 59 -

CLPT modified the plan terms of stock options granted on September 26, 2023 in October 2024; therefore, the exercise price changed from $15.30 to $14.10 per share. The modification did not cause any incremental fair value granted.

CLPT modified the plan terms of stock options granted on May 31, 2022 in October 2024; therefore, the exercise price changed from $15.30 to $14.10 per share. The modification did not cause any incremental fair value granted.

CLPT modified the plan terms of stock options granted on February 26, 2021 in October 2024; therefore, the exercise price changed from $14.40 to $13.30 per share. The modification did not cause any incremental fair value granted.

36.	CAPITAL MANAGEMENT

The Company manages its capital to ensure that entities in the Company will be able to continue as going concerns while maximizing the return to stakeholders through the optimization of the debt and equity balance.

The capital structure of the Company consists of debt of the Company and the equity attributable to the parent.

Some consolidated entities are required to maintain minimum paid-in capital amount as prescribed by the applicable laws.

The management reviews the capital structure of the Company as needed. As part of this review, the management considers the cost of capital and the risks associated with each class of capital. According to the management’s suggestions, the Company maintains a balanced capital structure through paying cash dividends, increasing its share capital, purchasing outstanding shares, and issuing new debt or repaying debt.

37.	FINANCIAL INSTRUMENTS

Fair Value Information

The fair value measurement guidance establishes a framework for measuring fair value and expands disclosure about fair value measurements. The standard describes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. These levels are:

Level 1 fair value measurements: These measurements are those derived from quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 fair value measurements: These measurements are those derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

Level 3 fair value measurements: These measurements are those derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs).

Financial instruments that are not measured at fair value but for which fair value is disclosed

Except those listed in the table below, the Company considers that the carrying amounts of financial assets and liabilities not measured at fair value approximate their fair values.

The fair value of bonds is measured using Level 2 inputs. The valuation of fair value is based on the quoted market prices provided by third party pricing services.

The fair values of financial assets and financial liabilities of Level 2 are determined as follows:

The fair values of financial assets and financial liabilities with standard terms and conditions and traded in active markets are determined with reference to quoted market prices.

For derivatives, fair values are estimated using discounted cash flow model. Future cash flows are estimated based on observable inputs including forward exchange rates at the end of the reporting periods and the forward and spot exchange rates stated in the contracts, discounted at a rate that reflects the credit risk of various counterparties.

The fair values of non-listed domestic and foreign equity investments and other investing agreements were Level 3 financial assets and determined using the market approach by reference the Price-to-Book ratios (P/B ratios) of peer companies that traded in active markets, using the income approach, in which the discounted cash flow is used to capture the present value of the expected future economic benefits to be derived from the investments, or using assets approach. The significant unobservable inputs used were listed in the below table. An increase in growth rate of long-term revenue, a decrease in discount for the lack of marketability or noncontrolling interests discount, or a decrease in the discount rate would result in increases in the fair values.


	September 30, 2025	December 31, 2024	September 30, 2024
Discount for lack of marketability	10.00%~30.00%	20.00%~30.00%	13.84%~20.00%
Noncontrolling interests discount	10.00%~29.04%	15.00%~29.04%	15.00%~25.00%
Growth rate of long-term revenue	1.33%	0.12%	0.12%
Discount rate	7.94%~10.80%	8.32%~14.40%	8.18%~14.00%

If the inputs to the valuation model were changed to reflect reasonably possible alternative assumptions while all the other variables were held constant, the fair values of Level 3 financial assets would increase (decrease) as below table.

Financial Risk Management Objectives

The main financial instruments of the Company include investments in equity and debt instruments, trade notes and accounts receivable, trade notes and accounts payable, lease liabilities, loans and bonds payable. The Company’s Finance Department provides services to its business units, co-ordinates access to domestic and international capital markets, monitors and manages the financial risks relating to the operations of the Company through internal risk reports which analyze exposures by degree and magnitude of risks. These risks include market risk (including foreign currency risk, interest rate risk and other price risk), credit risk, and liquidity risk.

- 66 -

The Company seeks to minimize the effects of these risks by using derivative financial instruments to hedge risk exposures. The use of financial derivatives is governed by the Company’s policies approved by the Board of Directors. Those derivatives are used to hedge the risks of exchange rate fluctuation arising from operating or investment activities. Compliance with policies and risk exposure limits is reviewed by the Company’s Finance Department on a continuous basis. The Company does not enter into or trade financial instruments, including derivative financial instruments, for speculative purposes.

Chunghwa reports the significant risk exposures and related action plans timely and actively to the audit committee and if needed to the Board of Directors.

Market risk

The Company is exposed to market risks of changes in foreign currency exchange rates and interest rates. The Company uses forward exchange contracts to hedge the exchange rate risk arising from assets and liabilities denominated in foreign currencies.

There were no changes to the Company’s exposure to market risks or the manner in which these risks are managed and measured.

Foreign currency risk

For details about the carrying amounts of the Company’s foreign currency denominated monetary assets and monetary liabilities at the balance sheet dates, please refer to Note 42 Significant Assets and Liabilities Denominated in Foreign Currencies.

The carrying amounts of the Company’s derivatives with exchange rate risk exposures at the balance sheet dates were as follows:


	September 30, 2025		December 31, 2024		September 30, 2024
Assets
USD	$	1,482	$	263	$	—
EUR		6,275		1,160		65
Liabilities
USD		68		—		951
EUR		—		1,907		791

Foreign currency sensitivity analysis

The Company is mainly exposed to the fluctuations of the currencies USD, EUR, SGD and RMB.

The following table details the Company’s sensitivity to a 5% increase and decrease in the functional currency against the relevant foreign currencies. 5% is the sensitivity rate used when reporting foreign currency risk internally to key management personnel and represents management’s assessment of the reasonably possible changes in foreign exchange rates. The sensitivity analysis includes only outstanding foreign currency denominated monetary items and forward exchange contracts. A positive number below indicates an increase in pre-tax profit or equity where the functional currency weakens 5% against the relevant currency.

This is mainly attributable to the exposure to foreign currency denominated receivables and payables of the Company outstanding at the balance sheet dates.

This is mainly attributable to forward exchange contracts.

This is mainly attributable to the changes in the fair value of derivatives that are designated as cash flow hedges.

For a 5% strengthening of the functional currency against the relevant currencies, there would be an equal and opposite effect on the pre-tax profit or equity for the amounts shown above.

Interest rate risk

The carrying amounts of the Company’s exposures to interest rates on financial assets and financial liabilities at the balance sheet dates were as follows:


	September 30, 2025		December 31, 2024		September 30, 2024
Fair value interest rate risk
Financial assets	$	25,205,797	$	47,562,672	$	33,406,988
Financial liabilities		36,223,823		41,444,583		41,547,929
Cash flow interest rate risk
Financial assets		14,739,532		12,949,846		10,667,961
Financial liabilities		2,355,000		1,785,000		1,965,000

Interest rate sensitivity analysis

The sensitivity analyses below have been determined based on the exposure to interest rates for non-derivative instruments at the end of the reporting period. A 25 basis point increase or decrease is used when reporting interest rate risk internally to key management personnel and represents management’s assessment of the reasonably possible change in interest rates.

If interest rates had been 25 basis points higher/lower and all other variables were held constant, the Company’s pre-tax income would increase/decrease by $30,961 thousand and $21,757 thousand for the nine months ended September 30, 2025 and 2024 respectively. This is mainly attributable to the Company’s exposure to floating interest rates on its financial assets, short-term and long-term loans.

- 68 -

Other price risk

The Company is exposed to equity price risks arising from holding other company’s equity. Equity investments are held for strategic rather than trading purposes. The management managed the risk through holding various risk portfolios. Further, the Company assigned finance and investment departments to monitor the price risk.

Equity price sensitivity analysis

The sensitivity analyses below have been determined based on the exposure to equity price risks at the end of the reporting period.

If equity prices had been 5% higher/lower, pre-tax profit and pre-tax other comprehensive income would have increased/decreased by $57,922 thousand and $284,128 thousand, respectively, as a result of the changes in fair value of financial assets at FVTPL and financial assets at FVOCI for the nine months ended September 30, 2025. If equity prices had been 5% higher/lower, pre-tax profit and pre-tax other comprehensive income would have increased/decreased by $49,707 thousand and $240,414 thousand, respectively, as a result of the changes in fair value of financial assets at FVTPL and financial assets at FVOCI for the nine months ended September 30, 2024.

Credit risk

Credit risk refers to the risk that a counterparty would default on its contractual obligations resulting in financial loss to the Company. The maximum credit exposure of the aforementioned financial instruments is equal to their carrying amounts recognized in the consolidated balance sheet as of the balance sheet date.

The Company has large trade receivables outstanding with its customers. A substantial majority of the Company’s outstanding trade receivables are not covered by collateral or credit insurance. The Company has implemented ongoing measures including enhancing credit assessments and strengthening overall risk management to reduce its credit risk. While the Company has procedures to monitor and limit exposure to credit risk on trade receivables, there can be no assurance such procedures will effectively limit its credit risk and avoid losses. This risk is heightened during periods when economic conditions worsen. As the Company serves a large number of unrelated consumers, the concentration of credit risk was limited.

The Company mitigates its financial credit risk by selecting counterparties with investment grade credit ratings and by limiting the exposure to any individual counterparty. The Company regularly monitors and reviews market conditions, and adjusts the limit applied to counterparties according to their credit standing.

In accordance with the Company’s investment and risk management policies, counterparties for debt investments must be financial institutions with investment grade or higher, and thus there is no significant credit exposure resulting from such investments. The Company assesses whether there has been a significant increase in credit risk on debt instruments since initial recognition by reviewing changes in financial market conditions, and external credit ratings and material information of the issuers.

The Company assesses the 12-month expected credit loss and lifetime expected credit loss for debt instruments based on the probability of default and loss given default provided by external credit rating agencies.

- 69 -

Liquidity risk

The Company manages and maintains sufficient cash and cash equivalent position to support the operations and reduce the impact on fluctuation of cash flow.

Liquidity and interest risk tables

The following tables detailed the Company’s remaining contractual maturity for its non-derivative financial liabilities with agreed repayment periods. The tables had been drawn up based on the undiscounted cash flows of financial liabilities based on the earliest date on which the Company is required to pay.
