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

Date of events: 2026/5/8

Contents:

**1.** **Date of occurrence of the event:** 

2026/5/8

**2.** **Year/Quarter of the financial report:** 

The first quarter of 2026

**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$10,607,722 thousand, consolidated net income attributable to stockholders of the parent of NT$10,109,931 thousand, and basic earnings per share of NT$1.30 for the three months ended March 31, 2026, respectively. The Company also reported total consolidated assets of NT$547,813,634 thousand, total consolidated liabilities of NT$136,380,954 thousand, and total consolidated equity of NT$411,432,680 thousand as of March 31, 2026.

**5.** **Accounting principles applied for securities issued overseas:** 

IAS 34 "Interim Financial Reporting" as issued by the International Accounting Standards Board ("IFRSs")

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

Under IFRSs, the Company reported consolidated net income of NT$10,122 million, consolidated net income attributable to stockholders of the parent of NT$9,611 million, and basic earnings per share of NT$1.24 for the three months ended March 31, 2026, respectively. The Company also reported total consolidated assets of NT$547,618 million, total consolidated liabilities of NT$138,991 million, and total consolidated equity of NT$408,627 million as of March 31, 2026.

**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 was 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.

**INDEPENDENT AUDITORS' REVIEW REPORT** 

PWCR26000051

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 March 31, 2026 and 2025, and the related consolidated statements of comprehensive income, of changes in equity and of cash flows for the three-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 March 31, 2026 and 2025, and of its consolidated financial performance and its consolidated cash flows for the three-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.

**CHUNGHWA TELECOM CO., LTD. AND SUBSIDIARIES** 

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS** 

**THREE MONTHS ENDED MARCH 31, 2026 AND 2025** 

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

**1.** **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.

**2.** **APPROVAL OF FINANCIAL STATEMENTS** 

The consolidated financial statements were approved by the Board of Directors on May 8, 2026.

**3.** **SUMMARY OF MATERIAL ACCOUNTING POLICY INFORMATION**

**Statement of Compliance** 

The accompanying consolidated financial statements have been prepared in conformity with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and the International Accounting Standard 34 "Interim Financial Reporting" endorsed and issued into effect by the Financial Supervisory Commission (the "FSC").

(Concluded)

a. 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.

b. CHIEF repurchased its stock between February and March 2026 and issued new shares in March 2025 as its
employees exercised options. Therefore, the Company's ownership interest in CHIEF changed to 58.56% and 59.29% as of March 31, 2025 and 2026, respectively.

c. 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.

d. CLPT issued new shares in December 2025 as its employees exercised options. Therefore, the Company's
ownership interest in CLPT decreased to 62.03% as of December 31, 2025.

e. 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 February 2025, May 2025, August 2025 and February 2026 as its employees exercised options. Therefore, the Company's
ownership interest in CHTSC decreased to 63.44%, 56.69% and 56.68% as of March 31, 2025, December 31, 2025 and March 31, 2026, respectively.

f. IISI was listed in November 2025. Chunghwa did not participate in the capital increase of its initial public
offering through public underwriting and disposed of some shares of IISI in accordance with applicable regulations and the price stabilization mechanism. Therefore, the Company's ownership interest in IISI decreased to 44.53% as of
December 31 2025. Chunghwa continues to control more than half of seats of the Board of Directors of IISI. As a result, the Company treated IISI as a subsidiary.

------

g. Chunghwa invested in and established CHAI in October 2025. Chunghwa obtained 100% ownership interest of CHAI.
CHAI's founding employees participated in the capital increase of CHAI in January 2026. Therefore, the Company's ownership interest in CHAI decreased to 80% as of March 31, 2026.

h. SENAO established SAKUYO in March, 2026. SENAO obtained 100% ownership interest of SAKUYO. As of March 31,
2026, the investment capital had not been remitted.

i. 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.

j. CHI disposed of some shares of CHPT from November to December 2025. Therefore, the Company's ownership
interest in CHPT decreased to 33.74% as of December 31, 2025. 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.

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

l. Chunghwa and CDCC Capital jointly established CDCCF in March 2026, with a combined ownership interest of 65%.
CDCC Capital acts as the general partner and is responsible for the operation and management of the partnership.

The following diagram presented information regarding the relationship and percentages of ownership interests between Chunghwa and its subsidiaries as of March 31, 2026.

**Other Material Accounting Policies** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Convertible bonds

The component parts of compound instruments (i.e., convertible bonds) issued by the Company are classified separately as financial liabilities and equity in accordance with the substance of the contractual arrangements and the definitions of a financial liability and an equity instrument.

On initial recognition, the fair value of the liability component is estimated using the prevailing market interest rate for similar non-convertible instruments. This amount is recognized as a liability and is subsequently measured at amortized cost using the effective interest method until it is extinguished upon conversion or at maturity.

The conversion option classified as equity is measured as the residual amount, determined by deducting the fair value of the liability component, as separately determined, from the fair value of the compound instrument as a whole. The resulting amount, net of income tax effects, is recognized in equity and is not subsequently remeasured. Upon exercise of the conversion option, the related liability component and the amount recognized in equity are transferred to common stock and additional paid-in capital - share premium. If the conversion option is not exercised upon maturity, the amount recognized in equity is transferred to additional paid-in capital - share premium.

Transaction costs relating to the issuance of convertible bonds are allocated to the liability and equity components in proportion to the gross proceeds allocated to each component. Transaction costs allocated to the liability component are included in the carrying amount of the liability, while transaction costs allocated to the equity component are recognized directly in equity.

**4.** **MATERIAL ACCOUNTING JUDGMENTS AND KEY SOURCES OF ESTIMATION, UNCERTAINTY AND ASSUMPTION** 

In the application of the Company's accounting policies, the management is required to make judgments, estimates and assumptions which are based on historical experience and other factors that are not readily apparent from other sources. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed by the management on an ongoing basis.

For the material accounting judgments and key sources of estimation, uncertainty and assumption applied in these consolidated financial statements, please refer to the consolidated financial statements for the year ended December 31, 2025.

------

**5.** **APPLICATION OF NEW AND REVISED STANDARDS AND INTERPRETATIONS** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Initial application of the amendments to the IFRSs endorsed and issued into effect by the FSC

The initial application of the amendments to the IFRSs issued by the International Accounting Standards Board and endorsed and issued into effect by the FSC does not have a material impact on the Company's consolidated financial statements.

The Company has applied the amendments to IFRS 9 and IFRS 7 - Contracts Referencing Nature-dependent Electricity, please refer to Note 41 for details.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. IFRSs issued by the IASB but not yet endorsed and issued into effect by the FSC

| IFRS 19 | Subsidiaries without Public Accountability: Disclosures | January 1, 2027 |
| Amendments to IAS 21 | Translation to a Hyperinflationary Presentation Currency | January 1, 2027 |

---

Note: The FSC announced in a press release in September 2025 that public companies will apply IFRS 18 starting from fiscal year 2028. In addition, entities may choose to adopt IFRS 18 earlier based on their requirements after the FSC endorses the standard.

IFRS 18 "Presentation and Disclosure in Financial Statements" will replace IAS 1. The standard introduces a defined structure of the statement of profit or loss, disclosure requirements related to management-defined performance measures, and guidance to enhance the principles of aggregation and disaggregation applying to the primary financial statements and notes.

Except for the above, as of the date the consolidated financial statements were authorized for issue, the Company is continuously assessing the possible impact that the application of above standards and interpretations will have on the Company's financial position and operating result and will disclose the relevant impact when the assessment is completed.

The Company holds the above foreign and domestic stocks for medium to long-term strategic purposes and expects to profit from long-term investment. Accordingly, the management elected to designate these investments in equity instruments at FVOCI as they believe that recognizing short-term fair value fluctuations of these investments in profit or loss is not consistent with the Company's strategy of holding these investments for long-term purposes.

CHIEF disposed of all its preferred shares in WT Microelectronics Co., Ltd. in February 2026 upon the redemption of the investment. The fair value of the disposed investment was $18,050 thousand, and the cumulative gain on disposal was $556 thousand.

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. 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 Company recognized the retained interest in CHST at the fair value on the date control was lost; therefore, the Company recognized the disposal gain of $15,290 thousand based on the difference between the fair value and the carrying amount. The disposal gain was included in other gains and losses in the consolidated statements of comprehensive income.

CVC completed its liquidation in August 2025.

CHST was approved to end and dissolve its business in July 2025.

In addition, the management considered the size of ownership interest and the dispersion of shares owned by the other stockholders, other holdings are not extremely dispersed. Chunghwa is not able to direct its relevant activities. Therefore, Chunghwa does not have control over NCB and merely has significant influence over NCB and treats it as an associate.

The Company invested in and obtained 50% ownership interest in CPFI. However, as the Company has only two out of five seats of the Board of Directors of CPFI, the Company has no control but significant influence over CPFI. Therefore, the Company recognized CPFI as an investment in associate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Important lease-in activities and terms

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.

The Company also leases land and buildings for the use of offices, server rooms, and stores with lease terms from 1 to 50 years. Most of the lease agreements for national land adjust the lease payment according to the changes of the announced land values by the authority. At the expiry of the lease term, the Company does not have bargain purchase options to acquire the assets.

The lease agreements for equipment include a contract between Chunghwa and ST-2 Satellite Ventures Pte., Ltd. to lease capacity on the ST-2 satellite. For the information of lease agreements with related parties, please refer to Note 38 for details.

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.

Prepayments for investments consisted of a total of $650,000 thousand jointly invested by Chunghwa and CDCC Capital in CDCCF in December 2025.

**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.

The following tables summarized the information relating to the hedges for foreign currency risk.

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. 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.

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 ended March 31, 2026 and 2025 are $232,964 thousand and $238,217 thousand, respectively.

As Chunghwa may settle the employee compensation in shares or cash, Chunghwa shall presume that it will be settled in shares and take those shares into consideration when calculating the weighted average number of outstanding shares used in the calculation of diluted EPS if the shares have a dilutive effect. The dilutive effect of the shares needs to be considered until the approval of the number of shares to be distributed to employees as compensation in the following year.

**34.** **SHARE-BASED PAYMENT ARRANGEMENT** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. 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 three months ended March 31, 2026 and 2025, respectively.

------

There were no employee stock options outstanding for the three months ended March 31, 2026; information about CHIEF's outstanding stock options for the three months ended March 31, 2025 was as follows:

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

---

| | |
|:---|:---|
|  | **Stock Options<br>Granted on<br>November 13,<br>2020** |
|  Grant-date share price (NT$) | $356.00 |

|  Expected life | 5 years |
|  Expected volatility | 34.61% |
|  Weighted average fair value of grants (NT$) | $173893 |

**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).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. 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.

---

(Concluded)

The fair values of bonds and Chunghwa's bonds payable are 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 value of CHPT's convertible bonds payeble is measured using Level 3 inputs. The valuation of fair value is based on present value, which is calculated based on the cash flow expected to be paid and discounted using the prevailing market interest rate for similar non-convertible instruments at balance sheet date.

Note: The fair value measurements for the equity investments were transferred from Level 3 to Level 1 at the end of reporting period, since quoted prices (unadjusted) in active market became available.

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

1) 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.

2) 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.

**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.

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.

a. 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.

1) 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 43 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:

<u>Foreign currency sensitivity analysis</u> 

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.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b) This is mainly attributable to forward exchange contracts.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c) 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.

2) 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:

---

| | | | |
|:---|:---|:---|:---|
|  | **March 31, <br>2026** | **December 31,<br>2025** | **March 31, <br>2025** |

<u>Interest rate sensitivity analysis</u> 

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 $28,691 thousand and $20,785 thousand for the three months ended March 31, 2026 and 2025, respectively. This is mainly attributable to the Company's exposure to floating interest rates on its financial assets, short-term and long-term loans.

3) 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.

<u>Equity price sensitivity analysis</u>

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 $59,044 thousand and $335,351 thousand, respectively, as a result of the changes in fair value of financial assets at FVTPL and financial assets at FVOCI for the three months ended March 31, 2026. If equity prices had been 5% higher/lower, pre-tax profit and pre-tax other comprehensive income would have increased/decreased by $51,212 thousand and $265,020 thousand, respectively, as a result of the changes in fair value of financial assets at FVTPL and financial assets at FVOCI for the three months ended March 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. 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.

1) 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.
