To enhance the Board of Directors' awareness and competencies regarding climate change issues, as well as their sensitivity to sustainability trends and green technology developments, the Group arranges annual training programs covering topics such as sustainability trends, sustainability- and climate-related risks, advancements in green technologies, and emerging domestic and international sustainability and climate regulatory trends. These programs support directors in strengthening their understanding of sustainability transitions and practical developments. During the reporting year, all 13 directors completed sustainability-related training, accumulating a total of 93 training hours.

**2.1.3 Trade-Offs in Policies Related to Sustainability-Related Risks and Opportunities** 

In governing sustainability- and climate-related matters, various decision-making dimensions are taken into account and the perspectives of different stakeholders are considered to the greatest extent possible. The Board of Directors, in its oversight of corporate strategy, review of material transactions, and supervision of risk management processes and related policies, evaluates sustainability- and climate-related considerations as presented by the responsible units and carefully weighs the potential impacts of all relevant factors in its decision-making.

**2.1.4 Target Setting for Sustainability-Related Risks and Opportunities, and Linkage to Performance and Remuneration Policies** 

The Group's oversight of the target-setting process for sustainability-related risks and opportunities, as well as the monitoring of progress against such targets, is detailed in "2.1.1 Governance Structure for Sustainability-Related Risks and Opportunities".

In addition, to foster sustainability and climate awareness and enhance response capabilities, the Group links the remuneration of directors and senior management at headquarters to corporate sustainability- and climate-related matters. This approach is designed to incentivize all employees to actively engage with sustainability and climate issues, strengthen the willingness to implement action plans, and ultimately enhance overall climate resilience, advancing the Group's proactive transition toward a low-carbon and sustainable pathway.

|:---|:---|
| &nbsp;&nbsp;&nbsp; Directors | To strengthen the alignment between directors' performance and the Company's sustainability vision, as well as its short-, medium-, and long-term strategic objectives, the Company has incorporated sustainability management and ESG-related issues into the evaluation dimensions set forth in the Regulations Governing the Performance Evaluation of the Board of Directors of Chunghwa Telecom Co., Ltd. The ESG evaluation dimension assesses directors' understanding of sustainability-related matters, their ongoing oversight of the Company's ESG performance, and the extent to which directors support and promote the Company's sustainability initiatives. The evaluation results serve as an important reference for continuously enhancing board governance quality and overall operational effectiveness. In addition to conducting annual internal self-evaluations, the Board commissions external professional institutions or teams of experts and scholars to conduct independent evaluations every three years, thereby providing objective perspectives and professional insights. |
| &nbsp;&nbsp;&nbsp; Executives | The Company has established the Regulations of Performance Management for Senior Executives, and Related Incentive Issuance Ruler, and in alignment with the Group's sustainability vision and strategy, has formally incorporated ESG indicators into its performance management framework. Senior executive compensation is explicitly linked to ESG performance. The relevant sustainability indicators include electricity consumption, renewable energy utilization, digital empowerment of small and medium-sized enterprises (SMEs), corporate governance, and international sustainability ratings. The ESG-linked weighting increased to 10% in 2022, thereby reinforcing accountability and incentivizing senior management to fully integrate ESG principles into day-to-day operations. The proportion will be progressively increased on an annual basis to reach 30% by 2025. |

**3.** **Strategies** 

**3.1** **Sustainability-Related Risks and Opportunities** 

To identify sustainability-related risks and opportunities that could reasonably be expected to affect the Group's development, the Group established, in 2024, a project task force for the implementation of the IFRS Sustainability Disclosure Standards. The task force operates under the supervision of the President, with joint leadership by the Senior Executive Vice President of Finance and the Senior Executive Vice President of Technology, to advance the disclosure of sustainability-related risks and opportunities.

In identifying sustainability-related risks and opportunities, the information used by the Group is based on reasonable and supportable data that can be obtained without incurring undue cost or effort as of the reporting date, including past events, current conditions, and forward-looking projections. This approach ensures that the primary users of general purpose financial reports can fully understand the impacts of such risks and opportunities on the Group's development.

The significant judgments involved in the preparation of the Group's sustainability-related financial disclosures follow the process set out in the table below:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp; Procedures | Description |
| &nbsp;&nbsp;&nbsp; **Step 1**<br> Consolidation of Group Sustainability-related Topics | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br> Through ongoing operational activities and continuous engagement and communication with stakeholders, the Group identifies sustainability-related topics by integrating its sustainability development framework with global sustainability disclosure standards, thereby recognizing sustainability-related risks and opportunities.<br> The primary bases and sources of analysis include:<br> • Sustainability Management Framework: Incorporating the Group's sustainability vision, development objectives, and historical material sustainability topics.<br>• Standards and Frameworks: Including the Sustainability Accounting Standards Board (SASB) Standards, IFRS S2 Industry-based Implementation Guidance, GRI Standards, and TCFD.<br>• Industry trends and benchmark cases from leading domestic and international peers.<br>• Perspectives from internal and external experts, as well as sustainability issues prioritized by stakeholders.<br>|
| &nbsp;&nbsp;&nbsp; **Step 2**<br> Identifying the Potential Impacts of Sustainability-related Risks and Opportunities on Current and Expected Financial Performance<br>| The Group analyzes interactions with stakeholders, society, the economy, and the natural environment across the value chain to identify how sustainability-related positive and negative events may affect the Group's business model and strategic direction. Furthermore, the Group assesses the extent to which these impacts may reasonably be expected to give rise to sustainability-related risks and opportunities in the short, medium, and long term, potentially influencing the Group's cash flows, access to financing, and cost of capital. |
| &nbsp;&nbsp;&nbsp; **Step 3**<br> Establishing Sustainability-related Metrics and Targets<br>| For material sustainability-related risks and opportunities, the Group establishes concrete management measures and sets short-, medium-, and long-term metrics and targets, accompanied by monitoring, evaluation, and tracking mechanisms. |

---

------

Furthermore, the Group implements a periodic issue-maintenance mechanism to ensure that, during each financial reporting period, any occurrence of significant events or substantial changes in circumstances is promptly identified and addressed. The Group has reassessed the scope of all relevant sustainability-related risks and opportunities across its operations and value chain.

**3.1.1** **Time Horizons: Definitions and Linkage to Strategic Planning Timelines** 

The Group classifies the time horizons within which sustainability-related risks and opportunities are expected to occur into short-term, medium-term, and long-term. The definitions are presented in the table below:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;**Period** | **Definition** | **Linkage to Strategic Decision-Making** |
| &nbsp;&nbsp;&nbsp; Short-<br> term | &nbsp;&nbsp;&nbsp;&nbsp; • Less than 1 year<br>• 2026<br>| In consideration of the Group's planning cycles for sustainability-related decision-making, as well as relevant national policies and regulatory requirements, the time horizons are categorized into short-term, medium-term, and long-term. |
| &nbsp;&nbsp;&nbsp;Medium-term | &nbsp;&nbsp;&nbsp;&nbsp; • More than 1 year and up to 5 years<br>• 2027 to 2031<br>| In consideration of the Group's planning cycles for sustainability-related decision-making, as well as relevant national policies and regulatory requirements, the time horizons are categorized into short-term, medium-term, and long-term. |
| &nbsp;&nbsp;&nbsp; Long-<br>term  | &nbsp;&nbsp;&nbsp;&nbsp; • More than 5 years<br>• 2032 and afterwards<br>| In consideration of the Group's planning cycles for sustainability-related decision-making, as well as relevant national policies and regulatory requirements, the time horizons are categorized into short-term, medium-term, and long-term. |

**3.2** **Impacts of Sustainability-Related Risks and Opportunities on Strategy and Decision-making** 

Based on the results of risk and opportunity identification, the Group considers aspects such as business operations, products and services, adaptation and mitigation activities, and R&D investments to formulate a sustainability vision, long-term strategies, and medium- to long-term targets that are appropriate for the Group's business model.

**3.2.1** **Sustainability Plan and Climate Transition Plan** 

In 2023, the Group officially obtained verification of its GHG reduction targets under the Science Based Targets initiative (SBTi). The Group's GHG reduction targets for 2030 are as follows: a 50% reduction in Scope 1 and Scope 2 emissions compared with the 2020 base year, and a 25% reduction in Scope 3 emissions compared with the 2021 base year. The Group is committed to achieving net-zero emissions by 2045, five years earlier than the 2050 target, in alignment with the global 1.5°C warming limit pathway outlined by the Intergovernmental Panel on Climate Change (IPCC).

The Group has developed a transition plan to address the aforementioned GHG reduction targets related to climate mitigation and adaptation, as well as the identified transition risks and associated opportunities. The specific actions are outlined as follows:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;**Specific Actions** | **Description and Progress of the Plan** | **Action Targets** |
| &nbsp;&nbsp;&nbsp;Climate-Related Products and Services | During the initial implementation stage, existing systems are integrated and IoT security and data management mechanisms are strengthened to establish a robust technological foundation. These efforts are expected to enable predictive maintenance and real-time disaster response, further enhancing operational efficiency and service reliability while creating greater service value and competitive advantages. | &nbsp;&nbsp;&nbsp;&nbsp; • Continuously expand and enhance the scale of climate resilience–related services, products, and solutions, broaden customer adoption and application, and increase their contribution to overall revenue.<br>|
| &nbsp;&nbsp;&nbsp;Technology-driven decarbonization in IDC data centers | &nbsp;&nbsp;&nbsp;&nbsp; 1. Actively Introducing Advanced Technologies to Enhance Data Center Energy Efficiency:<br> &nbsp;&nbsp;&nbsp;&nbsp;• Replaced outdated equipment with high-efficiency solutions, such as upgrading to magnetic levitation variable-speed chillers and ultra-high-efficiency pumps (IE3 or above).<br>&nbsp;&nbsp;&nbsp;&nbsp;• Expanded deployment of proprietary AI-driven energy-saving technologies to optimize operations, stabilize rack temperatures, and enhance power efficiency. For AI data center construction, direct liquid cooling solutions using Coolant Distribution Units (CDUs) were implemented to dissipate 65% of heat from computing nodes, thereby improving system performance, increasing energy efficiency, and reducing PUE.<br>2. Through these initiatives, the IDC achieved a PUE of approximately 1.587 in 2025, meeting the annual target and improving from 1.61 in 2024. | &nbsp;&nbsp;&nbsp;&nbsp; • By 2030, the IDC data center aims to achieve a Power Usage Effectiveness (PUE) of below 1.5.<br>|

| &nbsp;&nbsp;&nbsp;**Specific Actions** | **Description and Progress of the Plan** | **Action Targets** |
| &nbsp;&nbsp;&nbsp;RE100 | &nbsp;&nbsp;&nbsp;&nbsp; The Group joined the RE100 initiative in 2023, committing to achieve 100% renewable energy usage across all operations by 2040. In 2025, renewable energy procurement and self-generated power reached 88.679 million kWh (Note 1), including the following:<br> • Solar PV and green base station construction: With a cumulative total of 171 installations, achieving a total installed capacity of 13.1MWp.<br>• Renewable energy procurement: In 2025, an investment of hundreds of millions NTD was made to purchase renewable energy.<br>| &nbsp;&nbsp;&nbsp;&nbsp; • By 2030, IDC data centers are targeted to use 100% renewable energy.<br>• By 2040, all operational sites are expected to achieve 100% renewable energy usage.<br>|
| &nbsp;&nbsp;&nbsp;EV100 | &nbsp;&nbsp;&nbsp;&nbsp; <br> The Group officially joined the EV100 initiative in 2024, committing to achieve 100% electrification of engineering and official vehicles by 2030:<br> • By the end of 2025, replaced 386 engineering and official vehicles with electric vehicles.<br>| &nbsp;&nbsp;&nbsp;&nbsp; • From 2024 to 2026, 30%–50% of engineering and official vehicles will be gradually replaced with electric vehicles.<br>• By 2030, the Group aims to achieve full electrification of all engineering and official vehicles.<br>|
| &nbsp;&nbsp;&nbsp;Replacement of Aging, Energy-Intensive Equipment | <br> In 2025, the Group made an investment of hundreds of millions NTD to construct and procure energy-efficient equipment, including energy-saving measures for power systems, air conditioning, switching equipment, transmission equipment, access networks, and mobile devices. Compared to 2024, the replacement of outdated, energy-consuming equipment resulted in an overall electricity reduction of 44.3 million kWh (Note 1) and cost savings of approximately NT$186 million (based on an average rate of NT$4.19 per kWh).<br>| &nbsp;&nbsp;&nbsp;&nbsp; • Introduction and testing of energy-saving technologies and next-generation hardware (antennas and baseband modules) to compare energy-saving performance with previous equipment, and to develop optimal solutions that balance power efficiency, recovery time, and user experience.<br>|

|:---|:---|
| Note 1: | Regarding the electricity consumption data for 2025, where certain activity data could not be obtained due to data availability constraints, the Group applied reasonably obtainable and supportable information available as of the reporting date (including, where necessary, estimates based on prior-period data) to perform estimations. However, the emissions data derived from such estimations involve a high degree of uncertainty and may be subject to material revisions upon the availability of updated information in the subsequent year.  |

---

In advancing its net-zero transition strategy, the Group is required in the short term to allocate capital toward the replacement of energy-intensive equipment, the implementation of energy management and monitoring systems, and the expansion of renewable energy procurement. These initiatives are expected to drive an increase in capital expenditures and certain long-term procurement costs. However, the Group's assessment indicates that such investments will enhance energy efficiency and reduce electricity consumption over the medium to long term, thereby lowering operating costs and mitigating the risk of rising carbon fees and other compliance-related expenditures under increasingly stringent regulatory requirements. At the same time, the Group is leveraging its capabilities to provide customers with climate resilience–enhancing services and products, assisting corporate clients in strengthening carbon emissions management and improving energy efficiency. In doing so, the Group transforms regulatory compliance–driven risk factors into scalable sources of revenue from low-carbon products and services, thereby reinforcing the resilience of its business model and supporting long-term value creation.

------

To achieve the climate targets, the key assumptions, elements, and conditions involved in the formulation of the transition plan are as follows:

• Key Assumptions: Referring to the IEA NZE scenario, it is assumed that the global energy sector will achieve net-zero CO2 emissions by 2050 and will have deployed a broad portfolio of clean energy technologies.

• Elements: Assumptions include factors such as the cost of green electricity, maturity of carbon capture
technologies, renewable energy market conditions, existing infrastructure, and government policies, which align with the Group's transition strategies of "Technology-driven Decarbonization" and "Use of Renewable
Energy."

• Conditions: Under the SBTi (telecommunications sector) emission reduction plan, assuming the business model and
value chain remain unchanged, the Group commits to achieving net-zero emissions by 2045, in line with the IPCC's global 1.5°C warming limit pathway.

In addition, there are inherent limits to emission reductions within the value chain. According to the current guidance published by the Science Based Targets initiative (SBTi), once a company has achieved a substantial level of internal emissions reduction, it may pursue beyond-value-chain mitigation through the purchase of carbon credits. Such measures include forest carbon sequestration, high-quality carbon credits, carbon capture technologies, and initiatives to reduce forest degradation, thereby contributing to net-zero emissions. Accordingly, the Group participated in the first carbon credit procurement facilitated by the Taiwan Carbon Solution Exchange (TCSE) in 2023. Moving forward, the Group will continue to plan for and acquire high-quality carbon credits to honor its commitment to achieving net-zero emissions.

| &nbsp;&nbsp;&nbsp; Climate-Related Opportunities - Energy<br>Energy efficiency improvements to reduce electricity consumption and associated carbon pricing costs | By integrating power and environmental monitoring with system development technologies, the Group actively promotes and implements optimization and improvement of office spaces, data centers, and base station infrastructure to reduce electricity consumption.<br>Compared to 2024, total electricity consumption this year decreased by 44.3 million kWh, resulting in a reduction of approximately NT$186 million in electricity expense. (Note 4) | • **Expected Financial Impact**<br> The Group places energy efficiency and low-carbon solutions at the core of its strategy, leveraging its ICT capabilities and talent advantages to systematically invest capital expenditures and resources in advancing its"Technology-Driven Energy Saving and Carbon Reduction" strategy. In 2026, operating costs and expenses, including electricity costs, are expected to decrease by approximately NT$201 million (Note 4). In practice, the financial impact of operating revenue arising from related business opportunities has been incorporated into the measurement and disclosure under"Climate-Related Opportunities — Climate Resilience Products and Services," while the financial impact of capital expenditures required to implement the strategy has been incorporated into the measurement and disclosure under "Climate-Related Risks — Transition Risks."<br> • **Medium to Long-term Impacts**<br> The Group's medium to long-term energy efficiency and low-carbon initiatives include the in-house development of an intelligent Energy Operations Center (EOC) system to automatically collect and analyze electricity consumption data and to calibrate energy-saving performance in real time; the accelerated decommissioning of outdated, energy-intensive equipment; the continuous reduction of the average PUE of IDC data centers; and the promotion of IP migration for the public switched telephone network, etc. These actions are expected to structurally lower the unit cost of electricity, increase potential revenue, and reduce operating expenses. During the period from 2027 to 2040, the anticipated reduction in potential operating costs and expenses, including electricity expenses, is estimated at approximately NT$3.029 billion. In addition, the Group expects to avoid potential carbon fee charges of approximately NT$427 million during 2027 to 2030 (Note 5). However, the financial impact of operating revenue arising from related business opportunities has been incorporated into the measurement and disclosure under "Climate-Related Opportunities — Climate Resilience Products and Services," while the financial impact of capital expenditures required to implement the strategy has been incorporated into the measurement and disclosure under "Climate-Related Risks — Transition Risks." |

| &nbsp;&nbsp; Climate-Related Risks - Transition Risks<br>Increased compliance costs in response to the government's 2050 net-zero emissions policy | In response to sustainability compliance requirements and the enhancement of operational resilience, the Group has completed the procurement of green electricity, the replacement of high energy-consumption equipment, and the implementation of a GHG inventory system. During the reporting year, the increase in the proportion of renewable energy resulted in an increase in operating costs and expenses of approximately NT$216 million (Note 6), while capital expenditures for equipment replacement amounted to approximately NT$2.57 billion. The Group continues to allocate hundreds of millions of NTD in ongoing investments, representing more than 3% of the financial impact (Note 7), toward renewable energy procurement costs and capital expenditures for equipment replacement to further deepen our strategic deployment and advancement of renewable energy. | The Group's climate transition plan is implemented in alignment with the decarbonization pathways advocated by the SBTi. The primary strategies focus on two key pillars: technology-driven carbon reduction and renewable energy procurement. Taking into account the implementation progress of green electricity procurement and equipment upgrades, the potential impacts in the short term and the medium to long term are as follows:<br> • **Short-term Impact**<br> In accordance with the Group's SBTi targets, the Group will progressively increase the proportion of renewable energy used and implement GHG inventory and management systems. Increase in operating costs and expenses: approximately NT$395 million, primarily attributable to the increased proportion of renewable energy usage (Note 6).<br> Capital expenditures: approximately NT$2.239 billion, primarily for the replacement of outdated equipment.<br> • **Medium- to Long-term Impacts**<br> To achieve the SBTi-aligned decarbonization pathway, the Group will be required to further expand its procurement of renewable energy. As a result, operating expenses are expected to increase over the medium to long term. However, as the relevant green electricity procurement contracts are still under negotiation, the associated costs remain highly uncertain and therefore cannot be reliably disclosed at this stage. |

| &nbsp;&nbsp;&nbsp;Transition Risks / Carbon Pricing | &nbsp;&nbsp;&nbsp;&nbsp; **1. Climate-related policies in the jurisdictions where the Company operates are formulated in accordance with the Government's current policy framework.**<br> It is anticipated that the "2050 Net-Zero Emissions Pathway" will continue to be implemented. In addition, the Company will comply with the requirement set forth in Appendix I, "Designated Reduction Rates by Industry," of the Designated GHG Emissions Reduction Goals for Entities Subject to Carbon Fees, which stipulates that GHG emissions for "other industries" in the year 2030 shall be reduced by 42% compared with the base year 2021. | **IEA STEPs**<br> Under the Stated Policies Scenario (STEPS), Taiwan has set 2005 as the base year. The government's emission reduction targets are a 10% reduction by 2025, a 24% (±1%) reduction by 2030, and the achievement of net-zero emissions by 2050, with other policies assumed to remain unchanged.<br> **IEA Net Zero Emissions Scenario**<br> In assessing transition risks under the IEA Net Zero Emissions (NZE) Scenario, it is assumed that the government amends relevant legislation to set 2020 as the base year. Under this assumption, the emission reduction targets would be strengthened to a 21% reduction by 2025, a 42% reduction by 2030, and the achievement of net-zero emissions by 2050. | 2015–2050 | The scope of analysis covers all major operational sites of the Group. | &nbsp;&nbsp;&nbsp;&nbsp; 1. Impact Assessment:<br> Under the STEPS carbon price scenario, assuming business-as-usual (BAU) trends, the carbon fees payable are estimated to account for approximately 0.33–0.49% of annual revenue in 2030 and 2050. Under an active decarbonization scenario, the carbon fees are expected to account for approximately 0.21–0.31% of annual revenue in 2030, and 0.02–0.03% in 2050.<br> Under the NZE carbon price scenario, carbon fees under the BAU scenario are estimated to account for approximately 1.57% of annual revenue in 2030 and 2.17% in 2050. Under the active decarbonization scenario, carbon fees are expected to account for approximately 1.37% of annual revenue in 2030 and 0.14% in 2050.<br> 2. Resilience Capability:<br> The Group addresses transition risks arising from carbon pricing through "technology-driven emission reductions" and "renewable energy adoption" The detailed response strategies are outlined in "3.2.1 Sustainability Plan and Climate Transition Plan." |

| &nbsp;&nbsp;&nbsp;Physical Risk / Flooding Caused by Sea Level Rise | &nbsp;&nbsp;&nbsp;&nbsp; **2. Impact of Macroeconomic Trends**<br> According to the Chung-Hua Institution for Economic Research, based on its full-year forecast for 2025 and the development of emerging technologies, the annual economic growth rate is projected to reach 5.45%.<br> **3. Impact of Country- or Region-Level Variables**<br> According to official reports from the Taiwan Climate Change Projection Information and Adaptation Knowledge Platform and national meteorological observation authorities, climate model projections indicate that Taiwan's winter season is expected to gradually shorten, total annual precipitation is projected to increase, and the intensity of extreme rainfall events is likely to exhibit an increasing trend.<br> **4. Assumptions on Energy Use and Mix**<br> The Group expects to increase the proportion of electricity consumption from renewable energy sources to 100% by 2040. | &nbsp;&nbsp;&nbsp; **1.RCP2.6**<br> The IPCC uses Representative Concentration Pathways (RCPs) to model climate scenarios under varying levels of warming. RCP 2.6 represents a mitigation scenario, in which radiative forcing is projected to decrease by the year 2100.<br> **2.RCP 8.5**<br> • RCP 8.5 represents a high GHG emission scenario, in which radiative forcing is projected to continue increasing by 2100. In assessing physical risks, the Group selected three physical risk types that are most frequently observed in the telecommunications sector and for which domestic research data are available. The assessment parameters include: flooding caused by sea level rise, global temperature increase, and flood risk.<br>• Assumptions: It is assumed that future climate change trends will follow the projections in the "National Climate Change Science Report 2024: Phenomena, Impacts, and Adaptation," and that temperature increases due to climate change will exhibit the same trend across all of Taiwan.<br>• Analysis Factors: Severity of disaster caused by sea level rise, magnitude of global temperature increase, impact of flood-inducing natural hazards<br>| 2015–2100 |  | &nbsp;&nbsp;&nbsp;&nbsp; 1. Impact Assessment:<br> Using the NASA Sea Level Projection Tool, the future sea level rise in Taiwan was estimated under a global warming scenario of 2°C (closest to the projected temperature increase under RCP 8.5). For this assessment, the "National Climate Change Science Report 2024: According to studies, disasters caused by sea level rise are expected to occur after 2080 and, therefore, do not have a significant impact on the Group at present.<br> 2. Resilience Capability:<br> Based on the integrated scenario analysis, under a long-term 2°C warming scenario towards the low-carbon economy, some of the Group's data centers are located in high-risk coastal zones. However, the majority of data centers were designed prior to construction with considerations for wind resistance and sea level rise to ensure the safety of the facilities and the continuity of operations, assuming no further deterioration in climate change and global warming. |

| &nbsp;&nbsp;&nbsp;Physical Risk / Global Temperature Increase | &nbsp;&nbsp;&nbsp;&nbsp; **5. Assumptions on Technological Development**<br> With reference to Taiwan's "2050 Net-Zero Emissions Pathway," Taiwan is expected to develop low-carbon energy technologies in the short to medium term, while advancing high-efficiency green energy generation technologies over the long term. |  | 2015–2100 |  | &nbsp;&nbsp;&nbsp;&nbsp; 1. Impact Assessment:<br> According to the National Climate Change Science Report 2024, under the RCP 8.5 scenario, the mid-21st century (2041–2060) is projected to experience a temperature increase of 1.6°C, while by the end of the century (2081–2100), temperatures could rise by up to 3.4°C. The risks associated with rising temperatures are not significant for the Group, and are mainly reflected in increased electricity costs resulting from cooling needs at office areas or operating locations.<br> 2. Resilience Capability:<br> In recent years, Taiwan's warming trend has been approximately 0.32°C per decade, accompanied by a corresponding increase in electricity consumption. The Group has implemented an energy management system and established monitoring for major power-consuming equipment, setting electricity usage targets and ensuring effective control and management. |
| &nbsp;&nbsp;&nbsp;Physical Risk / Flood Risk |  |  | 2015–2099 |  | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1. Impact Assessment:<br> • Under the RCP 8.5 scenario, typhoon-induced waves exceeding 12 meters in height are projected to affect operational sites in Taitung County, as well as localized areas in Hualien County and Yilan County. Locations experiencing extreme storm surge heights exceeding 1.2 meters include New Taipei City, Yilan County, and parts of Taichung City, Yunlin County, Chiayi County, Hualien County, and Taitung County. Such conditions indicate extreme wind and rainfall, which increase the risk of damage to outdoor telecommunications equipment and base stations in the aforementioned counties.<br>• In the long-term scenario (including the mid-century period, 2040–2065, and the end-of-century period, 2075–2099), the probability of flooding gradually increases across counties, primarily affecting Changhua, Yunlin, Chiayi, Nantou, and Tainan.<br>• A comprehensive water stress analysis was conducted for operational sites using the World Resources Institute (WRI) tool, with evaluation years set at 2030 and 2050, under the pessimistic RCP 8.5 scenario. Additionally, the Group utilized the WRI tool to assess physical risks for key suppliers with annual transaction values exceeding NT$50 million. The analysis indicates that over 98% of key suppliers fall within low to moderate or below-low risk levels.<br>2. Resilience Capability:<br> The Group conducts an annual natural disaster preparedness inspection for all data centers. Flood protection measures include leak detection and waterproofing. The operations and maintenance unit issues notifications requiring all data center managers to perform safety checks, such as ensuring drainage openings are free of debris, verifying flood protection measures, and confirming the installation of waterproof gates. |

**3.3.1.3 Major Areas of Uncertainty Considered in Climate Resilience Assessment** 

To ensure the decision-usefulness of the resilience assessment, the Group considers several major areas of uncertainty, including policy changes, technological advancements, shifts in market demand, environmental changes, and economic factors. The areas of significant uncertainty are described as follows:

1. Policy Changes:

Governments worldwide may introduce new regulatory policies and requirements in response to the impacts of climate change. These may include adjustments to carbon fee rates, revisions to eligibility criteria for preferential mechanisms, and the tightening or expansion of resilience standards for critical infrastructure.

2. Technological Advancements:

With the rapid pace of technological development, the maturity and cost trajectories of data center energy-efficiency technologies, network cloudification/virtualization, power storage solutions, and AI-enabled energy-efficiency tools will influence both the marginal abatement cost and the timing of related investments.

3. Changes in Market Demand:

Market demand for low-carbon products and services may evolve over time. The Group must anticipate and adapt to such demand shifts to ensure that its offerings continue to meet customer expectations. These shifts include, but are not limited to, changes in demand for cloud/IDC colocation services, the impact of 5G/6G applications on power-use flexibility and peak–off-peak load structures, and evolving customer preferences for low-carbon service offerings, such as green colocation and green SLAs.

4. Environmental Changes:

Climate change may lead to an increase in extreme weather events, such as typhoons, severe rainfall, and sea-level rise. These environmental changes could significantly impact the Group's operations and value chain, particularly through risks to sites and submarine cable landing stations, including flood depth, wind and salt damage, power outage likelihood, and regional variations in exposure.

5. Economic Factors:

Global economic uncertainty may affect investment activities and capital flows. The Group must consider how changes in the economic environment may influence its financial position and operations, including but not limited to the effects of interest rate, exchange rate, and electricity price volatility on PPA pricing, CAPEX discounting, and operating costs.

**3.3.1.4 Adaptive Capacity of Climate-Transition Strategies and Business Model in the Short, Medium, and Long Term** 

The Group's strategy and business model are implemented based on the most reasonably likely scenarios. The Group assesses its capacity to adjust and adapt its strategy and business model, including the availability and flexibility of financial resources, the ability to reallocate and upgrade assets, and the impact of investments in climate-related mitigation, adaptation, and resilience opportunities, as described below:

• Availability and Flexibility of Financial Resources

The Group has remained profitable each year. The quick ratio has consistently been maintained above 90%, and the debt-to-asset ratio has been remained below 30%. The Group's existing financial resources are assessed to be adequate and sufficiently flexible.

• Capacity for Asset Reallocation and Upgrades

The Group allocates annual budgets for relevant implementation projects in accordance with its sustainability-related targets. Funding sources include not only net cash inflows from the Group's operating activities but also the issuance of sustainability bonds, serving as strategic funding to address sustainability-related risks and opportunities. In 2022 and 2025, the Group issued NT$3.5 billion in sustainability bonds each year, totaling NT$7 billion, thereby ensuring no constraints on its ability to reallocate, upgrade, or decommission existing assets.

• Impacts on Investments in Sustainability- and Climate-Related Mitigation, Adaptation, and Resilience
Opportunities

**4. Risk Management** 

**4.1 Processes and Policies for Identifying, Assessing, Prioritizing, and Monitoring Sustainability-Related Risks** 

Chunghwa Telecom's Board of Directors establishes the risk management policies, framework, and culture, and sets up a board-level functional committee, the Risk Management Committee, to oversee and review risk management policies, procedures, and frameworks. At the management level, the Risk Management Steering Committee is responsible for driving the implementation of company-wide risk control operations. The Audit Office reviews risk events, with realized risks reported to the Audit Committee, while imminent or preventive risks are reported to the Risk Management Committee.

In the processes for identifying, assessing, prioritizing, and monitoring sustainability- related risks, the assessment and management plans for sustainability-related risks are integrated into the Company's Enterprise Risk Management (ERM) framework, in line with the principle of materiality. To ensure timely evaluation of operational risks, annual identification of risk events, monthly reviews, assessments, and follow-ups are conducted, and potential new risk are continuously identified on a rolling basis. This ensures that all risk types—such as strategic risks, operational risks, and reporting/compliance risks—are properly identified. Control indicators and mitigation actions for each risk type are regularly and actively monitored to maintain the overall risk appetite within acceptable levels. In addition, no modifications were made to the risk identification and assessment processes during the reporting year.

|:---|:---|
| &nbsp;&nbsp;&nbsp;**Type** | **Assessment Methods for the Nature, Likelihood, and Impact of Sustainability- and Climate-Related Risks** |
| &nbsp;&nbsp;&nbsp;Sustainability-Related Risks | The assessment of sustainability-related risks is conducted in accordance with the double materiality principle. Dozens of senior executives involved in sustainability-related operations complete questionnaires for each topic to evaluate both the impact materiality and financial materiality, assessing the likelihood and magnitude of potential positive and negative impacts for each issue. |
| &nbsp;&nbsp;&nbsp;Climate-Related Risks | 1. Collecting and Identifying Climate Topics: Following the TCFD framework, the Group reviews the service models and characteristics of the telecommunications industry to compile a comprehensive list of climate-related risks and opportunities.<br> 2. Identifying Material Climate Risks and Opportunities: Internal and external inputs are gathered through questionnaires and interviews to assess the magnitude and urgency of impacts. Materiality thresholds are established, and material climate risks and opportunities are selected accordingly.<br> 3. Establishing a Material Climate Risk and Opportunity Matrix: Climate risks and opportunities are prioritized based on the double materiality principle, and annual priorities are determined. After internal review, a materiality matrix is produced, illustrating the ranking of each topic.<br> 4. Target Setting and Strategy Management: Based on the climate risk matrix, annual targets and strategies are formulated. Policy implementation is reviewed quarterly, plans are adjusted, and monitoring mechanisms are established to ensure target achievement and strengthened risk response. |

**4.1.3 Prioritization of Sustainability-Related Risks and Opportunities and the Methodology** 

The severity of operational impacts is assessed based on the likelihood and consequence of each risk event, and risks are prioritized using a risk matrix, with corresponding risk levels assigned. Risk mitigation actions are implemented according to the assigned risk level. (Expected Risk Value = Risk Impact × Risk Probability)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Risk Probability = likelihood of the risk occurring.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Risk Impact = severity of the risk's consequence.

Within the matrix, risks with higher expected values are defined as enterprise-level critical risks, serving as a priority action list for management and a basis for resource allocation.

![LOGO](g67626dsp017.jpg)

Note: The "Investments in business" risk event is assessed at the subsidiary level, whereas other risk events are primarily assessed for the parent company, Chunghwa Telecom.

**4.1.4 Mechanisms for Monitoring Sustainability**-**Related Risks and Opportunities** 

To achieve the four key control objectives—strategy, operations, reporting, and regulatory compliance—risk sources are analyzed based on strategic goals and internal and external environmental variables. Using a risk matrix, we identify and assess opportunities and risk events within the operating environment. Relevant managerial units then formulate strategies and risk response measures to carry out effective risk management and control:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• First Line of Defense: Undertaken by risk owners and individual operating units, focusing on day-to-day risk management and response. Risk controls are integrated into routine operational processes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Second Line of Defense: Led by the Risk Management Steering Committee and relevant functional units. This line is
responsible for overseeing, guiding, and adjusting risk management policies and mechanisms, as well as establishing standardized processes and procedures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Third Line of Defense: Led by the Audit Department, which conducts periodic internal audits to evaluate the
effectiveness and implementation of the overall risk management framework and provides recommendations for improvement based on identified issues.

Through the coordinated efforts of the three lines of defense, a multilayered protection system is established that reinforces robust operations and supports long-term sustainable development.

| &nbsp;&nbsp;&nbsp; 1. Purchased goods and services | Priority is given to estimating emissions using product life cycle GHG emission factors. For materials or products with available weight data (such as consumables, packaging materials, electronic components, and raw materials), emissions are calculated by multiplying the weight by the corresponding life cycle GHG emission factor (sources include the Environmental Protection Administration's Carbon Footprint Database or the SimaPro database). If such data are unavailable, quantification is performed using Environmentally Extended Input-Output (EEIO) analysis. The detailed calculation methods for each item are as follows:<br>1. Water (Carbon Footprint): Multiply the water consumption by the emission factor published on the Product Carbon Footprint Information Platform.<br>2. Supplier Inventory Items (Carbon Footprint): Based on the quantity of products procured, multiply by the emission factors announced by suppliers to calculate carbon emissions. This includes refrigerants, leased goods, SIM cards, and products sold in retail stores.<br>3. Others (EEIO): Classify the procurement items according to the industry classification standards of the Directorate-General of Budget, Accounting and Statistics, and calculate carbon emissions based on procurement costs using EEIO analysis. |
| &nbsp;&nbsp;&nbsp; 2. Procurement of<br>capital goods | The primary approach for quantification is Environmentally Extended Input-Output (EEIO) analysis. Based on the capital expenditures incurred during the year (such as IT equipment, servers, building renovations, vehicles, and facility installations), procurement amounts are classified according to the industry classification standards of the accounting system. These amounts are then multiplied by the corresponding industry-specific GHG emission factors for the manufacturing stage to calculate the indirect GHG emissions associated with the capital goods. |
| &nbsp;&nbsp;&nbsp; 3. Fuel and energy-related activities | Based on fuel and electricity consumption within the organizational boundaries defined for the inventory, indirect emissions are calculated by multiplying by the emission factors announced on the Product Carbon Footprint Information Platform (i.e., life-cycle emission factors excluding the use-phase emissions). |
| &nbsp;&nbsp;&nbsp; 4. Upstream transportation and distribution | Priority is given to using available material or product weight and delivery data to calculate emissions by applying the corresponding ton-kilometer emission factor approach (sources include the Environmental Protection Administration's Carbon Footprint Database or the SimaPro database). If such data are unavailable, emissions are quantified using the Environmentally Extended Input-Output (EEIO) method. The detailed calculation methods are as follows:<br>1. Supplier Inventory Items (Ton-Kilometer): For retail products, the parent company and subsidiaries estimate upstream transportation ton-kilometers based on inbound quantities, weights, supplier shipping records, and sales data. Emissions are calculated using ton-kilometer emission factors published on the Product Carbon Footprint Information Platform. For non-retail products (e.g., HGW, Wi-Fi AP, signal boosters, SIM cards, MOD), the same calculation principle applies. Subsidiaries calculate waste generation using per capita waste generation rates announced by authorities and employee headcount or total working hours, then apply incineration emission factors. Transportation emissions are calculated using the activity-based ton-kilometer method by multiplying waste transport weight and distance to the nearest incineration plant by the transport emission factor.<br>2. Accounting Items (EEIO): Based on expense records for upstream and downstream transportation and distribution, emissions are calculated using the EEIO approach by applying expenditure amounts, excluding non-product transportation expenses. |

| &nbsp;&nbsp;&nbsp; 5. Waste generated by operations | Priority is given to using available material or product weight and disposal method to calculate emissions by applying the corresponding ton-kilometer or emission factor approach (sources include the Environmental Protection Administration's Carbon Footprint Database or the SimaPro database). If such data are unavailable, emissions are quantified using the Environmentally Extended Input-Output (EEIO) method. The detailed calculation methods are as follows:<br>1. Waste Generation (Treatment Emission Factor): Based on the amount of general and industrial waste generated within the organizational boundary at each operating site, and the recorded waste treatment methods (including incineration, composting, and recycling), emissions are calculated by multiplying the waste quantity by the incineration emission factor published on the Product Carbon Footprint Information Platform; food waste is multiplied by the composting emission factor from the same source.<br>2. Waste Transportation (Ton-Kilometer): For municipal waste transported from operating sites to the final disposal location, emissions are calculated by multiplying the transport distance and weight by the ton-kilometer emission factor published on the Product Carbon Footprint Information Platform. For industrial waste transported from headquarters to treatment facilities, the same method applies.<br>3. Accounting Items (EEIO): Based on expense records for upstream and downstream transportation and distribution, emissions are calculated using the EEIO approach by applying expenditure amounts. |
| &nbsp;&nbsp;&nbsp; 6. Business travel | Priority is given to quantifying emissions using the activity-based method (passenger-kilometer approach). Actual business travel distances for each mode of transportation (e.g., air, rail, car, metro, high-speed rail) are aggregated and multiplied by the corresponding GHG emission factors for each transport mode. The detailed calculation methods are as follows:<br>1. Transportation (EEIO): Based on business travel classifications, including air transport, sea transport, rail transport, private car (taxi), coach/bus, and airport-related expenses, emissions are calculated using the Environmentally Extended Input-Output (EEIO) method by applying expenditure amounts.<br>2. Business Accommodation (EEIO): For domestic stays, emissions are quantified using the per-night emission factor published on the Product Carbon Footprint Information Platform; for international stays, SimaPro emission factors are applied. |
| &nbsp;&nbsp;&nbsp; 7. Employee commute | Both the parent company and subsidiaries conduct an employee commuting survey and require all employees to complete the questionnaire. After collecting data on commuting modes and distances, emissions are calculated by multiplying the corresponding public transportation emission factors. The calculation method is as follows:<br>1. Commuting Transportation (Passenger-Kilometer): For each county/city, commuting modes and distances are aggregated and then multiplied by the corresponding public transportation emission factors. The result is adjusted by the response rate (number of respondents ÷ total employees in that county/city) to estimate the commuting emissions for all employees nationwide. |

| &nbsp;&nbsp;&nbsp; 8. Upstream leased<br>assets | Priority is given to quantifying emissions from upstream lease-related accounting expenses using the Environmentally Extended Input-Output (EEIO) method, and to include electricity consumption for leased premises without full operational control. The detailed calculation methods are as follows:<br>1. Accounting Items (EEIO): Based on expense records for upstream leases, emissions are calculated using the EEIO approach by applying procurement costs, excluding service fees, usage fees, and attachment fees.<br>2. Electricity Without Full Operational Control (Electricity Emission Factor): For leased premises with fixed electricity charges and base stations without full operational control, emissions are calculated using the electricity emission factor. |
| &nbsp;&nbsp;&nbsp; 9. Downstream transportation and distribution | Priority is given to quantifying emissions using the transport activity-based method (ton-kilometer approach). Emissions are calculated by multiplying the weight of goods transported during product sales or service delivery by the transport distance to customers and applying the corresponding GHG emission factor for the transport mode (e.g., road, sea, air). If only accounting expense data are available, emissions are quantified using the Environmentally Extended Input-Output (EEIO) method (limited to subsidiary products). The detailed calculation methods are as follows:<br>1. Supplier Inventory Items (Ton-Kilometer): For products sold in retail stores where suppliers bear the transportation cost, ton-kilometers are estimated using the supplier's address and product weight. Emissions are calculated using the ton-kilometer emission factors published on the Product Carbon Footprint Information Platform or those provided by the SimaPro database.<br>2. EEIO Method: For downstream distribution or transportation-related accounting expenses, emissions are calculated by applying EEIO emission factors based on industry classification to reflect indirect emissions generated during product transportation. This method applies only to subsidiary products. |
| &nbsp;&nbsp;&nbsp; 10. Processing of Sold Products | As no intermediate products are sold under the current business model, processing of sold products is not applicable. |
| &nbsp;&nbsp;&nbsp; 11. Use of sold products | Priority is given to using available product carbon footprint information to quantify emissions based on the number of products sold. If such data are unavailable, emissions are quantified based on the product's energy consumption throughout its life cycle. The detailed calculation methods are as follows:<br>1. Product Carbon Footprint: Carbon emissions are calculated by multiplying the number of products sold by the use-phase emission factor announced by suppliers or associated products in the SimaPro database.<br>2. Product Electricity Consumption (Electricity Emission Factor): If annual electricity consumption data for individual electronic products announced by the Energy Administration or equipment lifetime standards from the Directorate-General of Budget, Accounting and Statistics are available, these are used to calculate product electricity consumption. If such data are unavailable, emissions are calculated by multiplying the number of products sold by estimated electricity consumption over the product's lifetime and then applying the latest 2024 electricity emission factor. Products without electricity consumption are excluded from carbon emission calculations. |
| &nbsp;&nbsp;&nbsp; 12. End-of-life treatment of sold products | The disposal method for each product is determined based on its composition and properties, considering potential end-of-life treatments such as incineration, landfill, or recycling. Emissions are then calculated by multiplying the corresponding end-of-life GHG emission factor for each treatment method. Emission factors are primarily sourced from the treatment stage data in the SimaPro life cycle assessment database. The detailed calculation methods are as follows:<br>1. Product Carbon Footprint: For sold products and SIM cards, carbon emissions are calculated by multiplying the sales volume by the end-of-life emission factor announced by suppliers or associated products in the SimaPro database.<br>2. Waste Treatment Volume (Weight-Based Emission Factor): Estimate the total weight based on product characteristics and apply the proportion of regulated recyclable materials announced by the Ministry of Environment to determine the total treatment volume. Multiply this by the emission factor published on the Product Carbon Footprint Information Platform for quantification.<br>3. Waste Transportation (Ton-Kilometer): Calculate emissions from transporting sold goods from operating sites to the Gangshan incineration plant by multiplying the transport distance and weight by the ton-kilometer emission factor published on the Product Carbon Footprint Information Platform. |

| &nbsp;&nbsp;&nbsp; 13. Downstream leased assets | Downstream leased products and premises are quantified based on electricity consumption. The detailed calculation methods are as follows:<br>1. Leased Product Electricity Consumption (Electricity Emission Factor): Carbon emissions are calculated by multiplying the product's rated power or standby and operating electricity consumption by the 2024 electricity emission factor published by the Energy Administration.<br>2. Leased Premises Electricity Consumption (Electricity Emission Factor): Carbon emissions are calculated by multiplying the electricity allocation recorded by external systems for leased premises by the latest 2024 electricity emission factor. This includes electricity used in IDC facilities subleased by subsidiaries. |
| &nbsp;&nbsp;&nbsp; 14. Franchise Business | There were no franchised operations in 2025. |
| &nbsp;&nbsp;&nbsp; 15. Investment | The primary focus is on assets with investment amounts disclosed in financial reporting documents, quantified using Environmentally Extended Input-Output (EEIO) analysis. If the investee company provides its Scope 1 and Scope 2 GHG emissions, emissions are further calculated based on the Company's equity share. The detailed calculation methods are as follows:<br>1. EEIO Method: In accordance with the GHG Protocol category for debt and equity investments, this includes investments accounted for under the equity method in consolidated financial statements, financial assets measured at fair value through other comprehensive income, and financial assets measured at fair value through profit or loss. All subsidiaries are included in the inventory scope, excluding liquidated or merged entities, and only companies with investment amounts are considered. Emissions are calculated by multiplying the Company's investment amount by the corresponding industry-specific EEIO emission factor to determine Scope 3 emissions attributable to subsidiaries.<br>2. Emission Factor Method: For companies that provide Scope 1 and Scope 2 emissions data, carbon emissions are calculated and then weighted based on the Company's equity share to determine Scope 3 emissions. |

|  | | | | | | **Potential Risks and Opportunities**<br> Risks:<br> • The international Internet transit price continues to decline, reducing the willingness of local ISPs to establish interconnection agreements.<br> • Remote interconnection models have become a new trend at Internet Exchange Points (IXPs). Large international IXPs establish Points-of-Presence (POPs) closer to local ISPs, enabling direct connection to international traffic and bypassing local IXPs, which poses a threat to local ISP interconnection markets.<br> • The New Telecommunications Act continues to regulate wholesale pricing for dominant market players. Declining Internet transit prices year by year affect ISP interconnection revenue.<br> • Internet Data Centers (IDCs) are attracting more content service providers, reducing the demand for ISP interconnection.<br> Opportunities:<br> • Domestic Internet Exchange Points in Taiwan may have insufficient interconnection trust, encouraging content service providers to explore bilateral interconnections with major operators and data centers.<br> • International content service providers strive to reduce network latency and improve user service quality by providing services closer to end-users. If a substantial local aggregation develops, it could increase interconnection demand for local small- and medium-sized ISPs.<br> • For details regarding the Taiwan Internet Exchange (TWIX), please refer to its official website.<br> • Chunghwa Telecom currently does not offer any zero-rating agreements. |

|  |  |  |  |  |  | (4) A fail-safe mechanism has been implemented to prevent service disruptions during SLF synchronization operations. In the event of an SLF malfunction, mobile registration signaling bypasses the SLF and queries user subscription information directly from the Home Subscriber Server (HSS), ensuring uninterrupted service. To strengthen disaster prevention, improve disaster response capabilities, and minimize losses, the Group has established the "Disaster Protection Operation Guidelines."<br> 2. The Group has also implemented "Emergency Disaster Response and Restoration Procedures" to address major disasters, including natural disasters, fires, explosions, and terrorist attacks, which may severely damage telecommunications network equipment. These procedures ensure emergency communication services in affected areas, minimizing service downtime. In the fixed-line communications segment, to prevent the escalation of disaster-related damage, we have reinforced the deployment of multi-route relay transmission in remote areas, wireless backup routing, expanded standby power capacity, and enhanced redundancy for both international and domestic submarine cable systems. These measures strengthen our overall disaster prevention and resilience capabilities. In addition, we conduct annual network and equipment dispatch and emergency repair drills to improve operational proficiency in disaster response and thereby reduce potential losses. Regarding mobile communications:<br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In the event that disasters cause disruptions to mobile communications, we have equipped 4WD off-road mobile base stations with high-orbit ST-2 or low-orbit OneWeb satellite antennas for signal transmission. These units can be rapidly deployed and set up based on on-site conditions in affected areas, enabling the swift restoration of mobile connectivity to the outside world. |

|  |  |  |  |  |  | 3. For critical transportation corridors with single access points—such as the Suhua Highway, South-Link Highway, and Alishan Highway—we have not only reinforced 4G/5G base station infrastructure and mobile communication multilayer coverage along the routes, but also conduct regular disaster-prevention drills to ensure the stable operation of mobile communication networks. These efforts enhance the disaster resilience and robustness of the mobile network. In the data communications segment, the Group's HiNet network adopts multi-route architecture with a highly reliable network redundancy mechanism, enabling real-time monitoring and traffic load balancing across all routes. For international routing, traffic is distributed across multiple submarine cable systems to prevent congestion or outages caused by single-route failures. Additionally, we collaborate with overseas carriers to increase direct international interconnection bandwidth, thereby improving the quality and stability of international internet connectivity. |

The Group is the largest distributor and agent of 3C products in Taiwan, and not a manufacturer of end-products. Nevertheless, we remain committed to minimizing potential health and safety risks to consumers. We assess and manage potential risks through the following measures to ensure that third-party products distributed and sold by our Group are subject to effective controls and adequate disclosure of chemical substances and hazardous materials:<br> During the procurement process, we require suppliers/agents to fulfill their obligation to disclose product information and to provide declarations/certificates regarding the use of chemicals and hazardous substances in the products they represent or supply.<br> Where feasible, suppliers must provide chemical control documentation or verification reports issued by original manufacturers or producers—such as REACH and RoHS certifications—so that our procurement teams can effectively implement chemical-related risk and hazard management.<br> 1. Chemical Management<br> (1) Chemical Usage Scenarios:<br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Currently, the Group primarily uses four types of chemicals in repair operations: isopropyl alcohol (IPA), cleaning agents, DOWSIL<sup>™</sup> SE 9160 Adhesive, and EH9777BS. These chemicals are used for cleaning and bonding handheld smart devices. Isopropyl alcohol and cleaning agents: Used for cleaning functions such as fingerprint and ink removal on device casings, full-device cleaning and disinfection, removal of adhesive residues during lamination, cleaning solder flux on motherboards, and removing copper chloride corrosion caused by moisture intrusion. DOWSIL<sup>™</sup> SE 9160 Adhesive and EH9777BS: Used for bonding processes, including the lamination of smartphone LCD panels. |

## Exhibit 99.2

**Exhibit 99.2** 

**Chunghwa Telecom Co., Ltd.** 

**Parent Only Financial Statements for the** 

**Years Ended December 31, 2025 and 2024 and** 

**Independent Auditors' Report** 

------

**INDEPENDENT AUDITORS' REPORT** 

PWCR25003504

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

**Opinion** 

We have audited the accompanying parent company only balance sheets of Chunghwa Telecom Co., Ltd. (the "Company") as of December 31, 2025 and 2024, and the related parent company only statements of comprehensive income, of changes in equity and of cash flows for the years then ended, and notes to the parent company only financial statements, including a summary of material accounting policy information.

In our opinion, the accompanying parent company only financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and its financial performance and its cash flows for the years then ended in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers.

**Basis for opinion** 

We conducted our audits in accordance with the Regulations Governing Financial Statement Audit and Attestation Engagements of Certified Public Accountants and Standards on Auditing of the Republic of China. Our responsibilities under those standards are further described in the Auditors' responsibilities for the audit of the parent company only financial statements section of our report. We are independent of the Company in accordance with the Norm of Professional Ethics for Certified Public Accountant of the Republic of China, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

**Key audit matters** 

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the Company's 2025 parent company only financial statements. These matters were addressed in the context of our audit of the parent company only financial statements as a whole and, in forming our opinion thereon, we do not provide a separate opinion on these matters.

Key audit matters for the Company's 2025 parent company only financial statements are stated as follows:

**Accuracy of revenues from mobile services, fixed-line broadband services and fixed-line data services** 

<u>Description</u> 

Refer to Note 3 for the accounting policies on revenue recognition and Notes 27 and 40 for details of revenue.The Company recognizes revenues from mobile services, fixed-line broadband services and fixed-line data services based on the terms of mobile services, fixed-line broadband services and fixed-line data services contracts and actual usage of mobile services, fixed-line broadband services and fixed-line data services.

------

Given that revenues from mobile services, fixed-line broadband services and fixed-line data services are comprised of a high volume of low-dollar transactions from a large number of contracts and a wide variety of tariff plans, the Company highly relies on the automated information systems to process and recognize revenues from mobile services, fixed-line broadband services and fixed-line data services.

Given the Company's revenues from mobile services, fixed-line broadband services and fixed-line data services are comprised of a high volume of low-dollar transactions and highly relies on information technology systems, a high degree of auditor effort was required in performing procedures related to accuracy of the Company's revenues from mobile services, fixed-line broadband services and fixed-line data services. Thus, we consider the accuracy of revenues from mobile services, fixed-line broadband services and fixed-line data services as a key audit matter.

<u>How our audit addressed the matter</u> 

Our audit procedures performed in respect of the above included the following:

1. Obtained an understanding over the design of internal controls and information systems related to the business
process of the Company's revenue recognition on mobile services, fixed-line broadband services and fixed-line data services and evaluated operating effectiveness of such controls. This includes the following procedures:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Obtained an understanding and evaluated the significant systems related to revenues from mobile services,
fixed-line broadband services and fixed-line data services, and tested the information technology general controls as well as the automated controls for automatic calculations and system interface over these systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Tested manual controls related to the review of information on mobile services, fixed-line broadband services and
fixed-line data services, including service acceptance, updates to price information, data collection and system interface, pricing, billing, and accounting processes.

2. Selected samples from mobile services, fixed-line broadband services and fixed-line data services revenues,
agreed the samples selected to service contracts, invoices, payment records, and tested consistency between the data entered into the system and the original service contracts.

**Responsibilities of management and those charged with governance for the parent company only financial statements** 

Management is responsible for the preparation and fair presentation of the parent company only financial statements in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers, and for such internal control as management determines is necessary to enable the preparation of parent company only financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the parent company only financial statements, management is responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

Those charged with governance, including the audit committee, are responsible for overseeing the Company's financial reporting process.

------

**Auditors' responsibilities for the audit of the parent company only financial statements** 

Our objectives are to obtain reasonable assurance about whether the parent company only financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors' report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the Standards on Auditing of the Republic of China will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these parent company only financial statements.

As part of an audit in accordance with the Standards on Auditing of the Republic of China, we exercise professional judgment and professional skepticism throughout the audit. We also:

1. Identify and assess the risks of material misstatement of the parent company only financial statements, whether
due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from
fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

2. Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control.

3. Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and
related disclosures made by management.

4. Conclude on the appropriateness of management's use of the going concern basis of accounting and, based
on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company's ability to continue as a going concern. If we conclude that a material uncertainty exists,
we are required to draw attention in our auditors' report to the related disclosures in the parent company only financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence
obtained up to the date of our auditors' report. However, future events or conditions may cause the Company to cease to continue as a going concern.

5. Evaluate the overall presentation, structure and content of the parent company only financial statements,
including the disclosures, and whether the parent company only financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

6. Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business
activities within the Company to express an opinion on the parent company only financial statements. We are responsible for the direction, supervision and performance of the audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

------

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the parent company only financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditors' report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

**NOTES TO FINANCIAL STATEMENTS** 

**YEARS ENDED DECEMBER 31, 2025 AND 2024** 

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

**1.** **GENERAL** 

Chunghwa Telecom Co., Ltd. ("the Company") was incorporated on July 1, 1996 in the Republic of China ("ROC"). The Company 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 the Company 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 the Company 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 the Company by reducing the government ownership to below 50% in various stages. In July 2000, the Company 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 the Company'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 the Company'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 the Company 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 the Company and completed the privatization plan.

The financial statements are presented in the Company's functional currency, New Taiwan dollars.

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

The financial statements were approved by the Board of Directors on February 26, 2026.

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

**Statement of Compliance** 

The accompanying financial statements have been prepared in conformity with the Regulations Governing the Preparation of Financial Reports by Securities Issuers.

**Basis of Preparation** 

The financial statements have been prepared on the historical cost basis except for certain financial instruments that are measured at fair values and net defined benefit liabilities (assets) which are measured at the present value of the defined benefit obligation less the fair value of plan assets.

------

When preparing the accompanying financial statements, the Company used equity method to account for its investment in subsidiaries, associates and joint ventures. In order for the amounts of the net profit, other comprehensive income and total equity in the parent company only financial statements to be the same with those amounts attributable to the owner of the Company in its consolidated financial statements, adjustments arising from the differences in accounting treatment between parent company only basis and consolidated basis were made to the captions of "investments accounted for using equity method", "share of profit (loss) of subsidiaries, associates and joint ventures accounted for using equity method", "share of other comprehensive income of subsidiaries, associates and joint ventures accounted for using equity method" and related equity items, as appropriate, in the parent company only financial statements.

**Current and Noncurrent Assets and Liabilities** 

Current assets include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Assets held primarily for the purpose of trading;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Assets expected to be realized within twelve months after the reporting period; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Cash and cash equivalents unless the asset is restricted from being exchanged or used to settle a liability for
at least twelve months after the reporting period.

Current liabilities include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Liabilities held primarily for the purpose of trading;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Liabilities due to be settled within twelve months after the reporting period; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Liabilities for which the Company on the balance sheet date does not have in substance the right to defer
settlement for at least twelve months after the reporting period.

Assets and liabilities that are not classified as current are classified as noncurrent.

**Foreign Currencies** 

In preparing the Company's financial statements, transactions in currencies other than the Company's functional currency (foreign currencies) are recognized at the rates of exchange prevailing at the dates of the transactions.

At the end of each reporting period, monetary items denominated in foreign currencies are retranslated at the rates prevailing at that date. Exchange differences on monetary items arising from settlement or translation are recognized in profit or loss in the period in which they arise.

Non-monetary items carried at fair value that are denominated in foreign currencies are retranslated at the rates prevailing at the date when the fair value was determined and related exchange differences are recognized in profit or loss. Conversely, when the fair value changes were recognized in other comprehensive income, related exchange difference shall be recognized in other comprehensive income.

Non-monetary items that are measured at historical cost in a foreign currency are not retranslated.

For the purpose of presenting financial statements, the assets and liabilities of the Company's foreign operations (including those subsidiaries, associates and joint ventures in other countries or currencies used different with the Company) are translated into New Taiwan dollars using exchange rates prevailing at the end of each reporting period. Income and expense items are translated at the average exchange rates for the period. Exchange differences arising, if any, are recognized in other comprehensive income.

------

**Cash Equivalents** 

Cash equivalents include those maturities within three months from the date of acquisition, highly liquid, readily convertible to a known amount of cash and are subject to an insignificant risk of changes in value such as commercial paper, negotiable certificates of deposit, time deposits and stimulus vouchers. These cash equivalents are held for the purpose of meeting short-term cash commitments.

**Inventories** 

Inventories are stated at the lower of cost or net realizable value item by item, except for those that may be appropriate to group items of similar or related inventories. Net realizable value is the estimated selling price of inventories less all estimated costs of completion and costs necessary to make the sale. The calculation of the cost of inventory is derived using the weighted-average method.

**Investments Accounted for Using Equity Method** 

Investments in subsidiaries, associates and joint ventures are accounted for using equity method.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Investment in subsidiaries

Subsidiaries are the entities controlled by the Company.

Under the equity method, the investment in subsidiaries is initially recognized at cost and the increase or decrease of carrying amount reflects the recognition of the Company's share of profit or loss and other comprehensive income of the subsidiaries after the date of acquisition. Besides, the Company also recognizes the Company's share of the change in other equity of the subsidiaries.

Changes in the Company's ownership interests in subsidiaries that do not result in the Company's loss of control over the subsidiaries are accounted for as equity transactions. Any difference between the carrying amounts of the investment of the subsidiaries and the fair value of the consideration paid or received is recognized directly in equity.

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 acquisition cost in excess of the acquisition-date fair value of the identifiable net assets acquired is recognized as goodwill, which is included within the carrying amount of the investment and shall not be amortized. The acquisition-date fair value of the net identifiable assets acquired in excess of the acquisition cost is recognized immediately in profit or loss.

Unrealized profits and losses from downstream transactions with a subsidiary are eliminated in full. Profits and losses from upstream transactions with a subsidiary and sidestream transactions between subsidiaries are recognized in the Company's financial statements only to the extent of interests in the subsidiary that are not related to the Company.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Investments in associates and joint ventures

An associate is an entity over which the Company has significant influence and that is neither a subsidiary nor an interest in a joint venture. A joint venture is a joint arrangement whereby the Company and other parties that have joint control of the arrangement have rights to the net assets of the arrangement.

Under the equity method, an investment in an associate and a joint venture is initially recognized at cost and adjusted thereafter to recognize the Company's share of profit or loss and other comprehensive income of the associate and joint venture as well as the distribution received. The Company also recognizes its share in changes in the associates and joint ventures.

When the Company subscribes for new shares of an associate and a joint venture at a percentage different from its existing ownership percentage, the resulting carrying amount of the investment differs from the amount of the Company's proportionate interest in the associate and joint venture. The Company records such a difference as an adjustment to investments with the corresponding amount charged or credited to additional paid-in capital. When the adjustment should be debited to additional paid-in capital but the additional paid-in capital recognized from investments accounted for using equity method is insufficient, the shortage is debited to retained earnings.

Any excess of the cost of acquisition over the Company's share of the fair value of the identifiable net assets and liabilities of an associate and a joint venture at the date of acquisition is recognized as goodwill, which is included within the carrying amount of the investment and shall not be amortized. Any excess of the Company's share of the net fair value of the identifiable assets and liabilities over the cost of acquisition is recognized immediately in profit or loss.

The entire carrying amount of an investment (including goodwill) is tested for impairment as a single asset by comparing its recoverable amount with its carrying amount. Any impairment loss recognized is not allocated to any asset, including goodwill, that forms part of the carrying amount of the investment. Any reversal of that impairment loss is recognized to the extent that the recoverable amount of the investment subsequently increases.

The Company discontinues the use of the equity method from the date on which its investment ceases to be an associate and a joint venture. Any retained investment is measured at fair value at that date, and the fair value is regarded as the investment's fair value on initial recognition as a financial asset. The difference between the previous carrying amount of the associate and joint venture attributable to the retained interest and its fair value is included in the determination of the gain or loss on disposal of the associate and joint venture. The Company accounts for all amounts previously recognized in other comprehensive income in relation to that associate and joint venture on the same basis as would be required had that associate and joint venture directly disposed of the related assets or liabilities.

When the Company transacts with its associate and joint venture, profits and losses resulting from the transactions with the associate and joint venture are recognized in the Company's financial statements only to the extent of interests in the associate and joint venture that are not related to the Company.

**Property, Plant and Equipment** 

Property, plant and equipment are initially measured at cost and subsequently measured at cost less accumulated depreciation and accumulated impairment loss.

Property, plant and equipment in the course of construction are depreciated and classified to the appropriate categories of property, plant and equipment when completed and ready for their intended use.

------

Depreciation on property, plant and equipment is recognized using the straight-line method. Each significant part is depreciated separately. Freehold land is not depreciated. The estimated useful lives, residual values and depreciation method are reviewed at the end of each year, with the effect of any changes in estimate accounted for on a prospective basis.

On derecognition of an item of property, plant and equipment, the difference between the net disposal proceeds and the carrying amount of the asset is recognized in profit or loss in the period in which the property is derecognized.

**Investment Properties** 

Investment properties are properties held to earn rentals and/or for capital appreciation. Investment properties also include land held for a currently undetermined future use.

Investment properties are measured initially at cost, including transaction costs. Subsequent to initial recognition, investment properties are measured at cost less accumulated depreciation and accumulated impairment loss. Depreciation is recognized using the straight-line method.

For a transfer from the investment properties to property, plant and equipment, the deemed cost of the property, plant and equipment for subsequent accounting is its carrying amount at the commencement of owner-occupation.

For a transfer from the property, plant and equipment to investment properties, the deemed cost of the investment properties for subsequent accounting is its carrying amount at the end of owner-occupation.

On derecognition of the investment properties, the difference between the net disposal proceeds and the carrying amount of the asset is recognized in profit or loss in the period in which the property is derecognized.

**Intangible Assets** 

Intangible assets with finite useful lives that are acquired separately are initially measured at cost and subsequently measured at cost less accumulated amortization and accumulated impairment loss. Amortization is recognized on a straight-line basis. The estimated useful life, residual value, and amortization method are reviewed at the end of each reporting period, with the effect of any changes in estimate being accounted for on a prospective basis. The residual value of an intangible asset with a finite useful life shall be assumed to be zero unless the Company expects to dispose of the intangible asset before the end of its economic life. Intangible assets with indefinite useful lives are measured at cost less accumulated impairment loss.

Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in profit or loss in the period in which the asset is derecognized.

**Impairment of Property, Plant and Equipment, Right-of-use Assets, Investment Properties, Intangible Assets and Incremental Costs of Obtaining Contracts** 

At the end of each reporting period, the Company reviews the carrying amounts of its property, plant and equipment, right-of-use assets, investment properties and intangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss. When it is not possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the cash-generating unit to which the asset belongs.

Intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment at least annually and whenever there is an indication that the assets may be impaired.

------

Recoverable amount is the higher of fair value less costs to sell and value in use. If the recoverable amount of an asset or cash-generating unit is estimated to be less than its carrying amount, the carrying amount of the asset or cash-generating unit is reduced to its recoverable amount, with the resulting impairment loss recognized in profit or loss.

Impairment loss from the assets related to incremental cost of obtaining contracts is recognized to the extent that the carrying amount of the assets exceeds the remaining amount of consideration that the Company expects to receive in exchange for related goods or services less the costs which relate directly to providing those goods or services.

When an impairment loss is subsequently reversed, the carrying amount of the asset or cash-generating unit is increased to the revised estimate of its recoverable amount, but only to the extent of the carrying amount that would have been determined had no impairment loss been recognized for the asset or cash-generating unit in prior years. A reversal of an impairment loss is recognized in profit or loss.

**Financial Instruments** 

Financial assets and financial liabilities are recognized when the Company becomes a party to the contractual provisions of the instruments.

Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition of financial assets and financial liabilities (other than financial assets and financial liabilities at fair value through profit or loss) are added to the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at fair value through profit or loss are recognized immediately in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Financial assets

All regular way purchases or sales of financial assets are recognized and derecognized on a trade date basis.

1) Measurement category

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a) Financial assets at fair value through profit or loss (FVTPL)

Financial asset is classified as at FVTPL when the financial asset is mandatorily classified as at FVTPL. Financial assets mandatorily classified as at FVTPL include investments in equity instruments which are not designated as at fair value through other comprehensive income (FVOCI).

Financial assets at FVTPL are stated at fair value, with any gains or losses arising on remeasurement recognized in profit or loss. The net gain or loss recognized in profit or loss does not incorporate any dividend earned on the financial asset. Fair value is determined in the manner described in Note 33.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b) Financial assets at amortized cost

Financial assets that meet the following conditions are subsequently measured at amortized cost:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. The financial asset is held within a business model whose objective is to hold financial assets in order to
collect contractual cash flows; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. The contractual terms of the financial asset give rise on specified dates to cash flows that are solely
payments of principal and interest on the principal amount outstanding.

------

Subsequent to initial recognition, financial assets at amortized cost are measured at amortized cost, which equals to gross carrying amount determined by the effective interest method less any impairment loss, except for short-term receivables as the effect of discounting is immaterial. Exchange differences are recognized in profit or loss.

Interest income is calculated by applying the effective interest rate to the gross carrying amount of such financial assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c) Investments in equity instruments at FVOCI

On initial recognition, the Company may make an irrevocable election to designate investments in equity instruments as at FVOCI. Designation at FVOCI is not permitted if the equity investment is held for trading or if it is contingent consideration recognized by an acquirer in a business combination.

Investments in equity instruments at FVOCI are subsequently measured at fair value with gains and losses arising from changes in fair value recognized in other comprehensive income and accumulated in other equity. The cumulative gain or loss will not be reclassified to profit or loss on disposal of the equity investments. Instead, it will be transferred to retained earnings.

Dividends on these investments in equity instruments are recognized in profit or loss when the Company's right to receive the dividends is established, unless the dividends clearly represent a recovery of part of the cost of the investment.

2) Impairment of financial assets and contract assets

The Company recognizes a loss allowance for expected credit losses on financial assets at amortized cost (including accounts receivable) and contract assets.

The Company recognizes lifetime Expected Credit Loss (ECL) for accounts receivable and contract assets. For all other financial instruments, the Company recognizes lifetime ECL when there has been a significant increase in credit risk since initial recognition. If, on the other hand, the credit risk on the financial instrument has not increased significantly since initial recognition, the Company measures the loss allowance for that financial instrument at an amount equal to 12-month ECL.

Expected credit losses reflect the weighted average of credit losses with the respective risks of a default occurring as the weights. Lifetime ECL represents the expected credit losses that will result from all possible default events over the expected life of a financial instrument. In contrast, 12-month ECL represents the portion of ECL that is expected to result from default events on a financial instrument that are possible within 12 months after the reporting date.

The Company recognizes an impairment loss for all financial instruments with a corresponding adjustment to their carrying amount through a loss allowance account.

3) Derecognition of financial assets

The Company derecognizes a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another entity.

On derecognition of a financial asset at amortized cost in its entirety, the difference between the asset's carrying amount and the sum of the consideration received and receivable is recognized in profit or loss.

------

On derecognition of investments in equity instruments at FVOCI in its entirety, the cumulative gain or loss is directly transferred to retained earnings, and it is not reclassified to profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Financial liabilities

1) Subsequent measurement

Except for financial liabilities at FVTPL, all the financial liabilities are subsequently measured at amortized cost using the effective interest method.

2) Derecognition of financial liabilities

The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable, including any non-cash assets transferred or liabilities assumed, is recognized in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Derivative financial instruments

The Company enters into derivative financial instruments to manage its exposure to foreign exchange rate risks, including forward exchange contracts.

Derivatives are initially measured at fair value at the date the derivative contracts are entered into and are subsequently remeasured to their fair value at the end of each reporting period. The resulting gain or loss is recognized in profit or loss immediately unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship. When the fair value of derivative financial instruments is positive, the derivative is recognized as a financial asset; when the fair value of derivative financial instruments is negative, the derivative is recognized as a financial liability.

**Hedge Accounting** 

The Company designates some derivatives instruments as cash flow hedges. Hedges of foreign exchange risk on firm commitments are accounted for as cash flow hedges.

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in profit or loss.

The associated gains or losses that were recognized in other comprehensive income are reclassified from equity to profit or loss as a reclassification adjustment in the line item relating to the hedged item in the same period when the hedged item affects profit or loss. If a hedge of a forecast transaction subsequently results in the recognition of a non-financial asset or a non-financial liability, the associated gains and losses that were recognized in other comprehensive income are removed from equity and are included in the initial cost of the non-financial asset or non-financial liability.

The Company discontinues hedge accounting only when the hedging relationship ceases to meet the qualifying criteria; for instance, when the hedging instrument expires or is sold, terminated or exercised. The cumulative gain or loss on the hedging instrument that has been previously recognized in other comprehensive income from the period when the hedge was effective remains separately in equity until the forecast transaction occurs. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in equity is recognized immediately in profit or loss.

------

**Provisions** 

Provisions are measured at the best estimate of the expenditure required to settle the Company's obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. The provisions for warranties claims are made by management according to the sales agreements which represent the management's best estimate of the future outflow of economic benefits. The provisions of warranties claims are recognized as operating cost in the period in which the goods are sold. The provision for onerous contracts represents the present obligation resulting from the measurement for the unavoidable costs of meeting the Company's contractual obligations exceed the economic benefits expected to be received from the contracts. In assessing whether a contract is onerous, the cost of fulfilling a contract includes both the incremental costs of fulfilling that contract and an allocation of other costs that are related directly to fulfilling contracts. The provision for decommissioning liabilities is recognized in accordance with the contractual requirements. The Company bears dismantling, removing the asset and restoring the site obligations for certain handsets base stations in the future. A provision is recognized for the costs to be incurred for fulfilling these obligations.

**Revenue Recognition** 

The Company identifies the performance obligations in the contract with the customers, allocates transaction price to each performance obligation and recognizes revenue when performance obligations are satisfied.

Sales of products are recognized as revenue when the Company delivers products and the customer accepts and controls the product. Except for the consumer electronic products such as mobile devices sold in channel stores which are usually in cash sale, the Company recognizes revenues for sale of other electronic devices and corresponding trade notes and accounts receivable.

Usage revenues from fixed-line services (including local, domestic long distance and international long distance telephone services), mobile services, internet and data services, and interconnection and call transfer fees from other telecommunications companies and carriers are billed in arrears and are recognized based upon seconds or minutes of traffic processed when the services are provided in accordance with contract terms. The usage revenues and corresponding trade notes and accounts receivable are recognized monthly.

Other revenues are recognized as follows: (a) one-time subscriber connection fees (on fixed-line services) are first recognized as contract liabilities and revenues are recognized subsequently over the average expected customer service periods, (b) monthly fees (on fixed-line services, mobile, internet and data services) and related receivables are accrued monthly, and (c) prepaid services (fixed-line, mobile, internet and data services) are recognized as contract liabilities upon collection considerations from customers and are recognized as revenues subsequently based upon actual usage by customers.

Where the Company enters into transactions which involve both the provision of telecommunications service bundled with products such as handsets, total consideration received from products and telecommunications service in these arrangements are allocated based on their relative stand-alone selling price. The amount of sales revenue recognized for products is not limited to the amount paid by the customer for the products. When the amount of sales revenue recognized for products exceeded the amount paid by the customer for the products, the difference is recognized as contract assets. Contract assets are reclassified to accounts receivable when the amounts become collectible from customers subsequently. When the amount of sales revenue recognized for products was less than the amount paid by the customer for the products, the difference is recognized as contract liabilities and revenues are recognized subsequently when the telecommunications services are provided.

------

For project business contracts, if a substantial part of the Company's promise to customers is to manage and coordinate the various tasks and assume the risks of those tasks to ensure the individual goods or services are incorporated into the combined output, they are treated as a single performance obligation since the Company provides a significant integration service. The Company recognizes revenues and corresponding accounts receivable when the project business contract is completed and accepted by customers. For some project contracts, the Company does not create an asset with an alternative use to the Company and has an enforceable right to payment for performance completed to date; therefore, performance obligations are satisfied and revenues are recognized over time.

For service contracts such as maintenance and warranties, customers simultaneously receive and consume the benefits provided by the Company; thus revenues and corresponding accounts receivable of service contracts are recognized over the related service period.

When another party is involved in providing goods or services to a customer, the Company is acting as a principal if it controls the specified good or service before that good or service is transferred to a customer; otherwise, the Company is acting as an agent. When the Company is acting as a principal, gross inflow of economic benefits arising from transactions is recognized as revenue. When the Company is acting as an agent, revenue is recognized as its share of transaction.

**Incremental Costs of Obtaining Contracts** 

Commissions and equipment subsidy related to telecommunications service as a result of obtaining contracts are recognized as an asset under the incremental costs of obtaining contracts to the extent the costs are expected to be recovered, and are amortized over the contract period. However, the Company elects not to capitalize the incremental costs of obtaining contracts if the amortization period of the assets that the Company otherwise would have recognized is expected to be one year or less.

**Leasing** 

At inception of a contract, the Company assesses whether the contract is, or contains, a lease.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. The Company as lessor

Rental income from operating leases is recognized on a straight-line basis over the term of the relevant lease.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. The Company as lessee

The Company recognizes right-of-use assets and lease liabilities for all leases at the commencement date of a lease, except for lease payments for low-value assets are recognized as expenses on a straight-line basis over the lease terms accounted for applying recognition exemption.

Right-of-use assets are initially measured at cost, which comprises the initial measurement of lease liabilities and for lease payments made at or before the commencement date. Right-of-use assets are subsequently measured at cost less accumulated depreciation and accumulated impairment losses and adjusted for any remeasurement of the lease liabilities. Right-of-use assets are presented separately on the balance sheets.

Right-of-use assets are depreciated using the straight-line basis from the commencement dates to the earlier of the end of the useful lives of the right-of-use assets or the end of the lease terms.

Lease liabilities were initially measured at the present value of the lease payments, which comprise fixed payments, in-substance fixed payments, variable lease payments which depend on an index or a rate. The lease payments are discounted using the interest rate implicit in a lease, if that rate can be readily determined. If such rate cannot be readily determined, the lessee's incremental borrowing rate is used.

------

Lease liabilities are subsequently measured at amortized cost using the effective interest method, with interest expense recognized over the lease terms. When there is a change in a lease term, a change in future lease payments resulting from a change in an index or a rate used to determine those payments, the Company remeasures the lease liabilities with a corresponding adjustment to the right-of-use assets. However, if the carrying amount of the right-of-use assets is reduced to zero, any remaining amount of the remeasurement is recognized in profit or loss. The Company accounts for the remeasurement of the lease liability as a result of the decrease of lease scope by decreasing the carrying amount of the right-of-use assets and recognizes in profit or loss any gain or loss on the partial or full termination of the lease. Lease liabilities are presented separately on the balance sheets.

Variable lease payments not depending on an index or a rate are recognized as expenses in the periods in which they are incurred.

**Borrowing Costs** 

All borrowing costs are recognized in profit or loss in the period in which they are incurred.

**Government Grants** 

Government grants are not recognized until there is reasonable assurance that the Company will comply with the conditions attached to government grants and that the grants will be received.

Government grants related to income are recognized in profit or loss on a systematic basis over the periods in which the Company recognizes expenses of the related costs for which the grants are intended to compensate. Specifically, government grants whose primary condition is that the Company should construct noncurrent assets are recognized as deferred revenue and transferred to profit or loss on a systematic and rational basis over the useful lives of the related assets.

Government grants that become receivable as compensation for expenses or losses already incurred are recognized in profit or loss in the period in which they become receivable.

**Employee Benefits** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Short-term employee benefits

Liabilities recognized in respect of short-term employee benefits are measured at the undiscounted amount of the benefits expected to be paid in exchange for the related service.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Retirement benefits

Payments to defined contribution retirement benefit plans are recognized as an expense when employees have rendered service entitling them to the contributions.

Defined benefit costs (including service cost, net interest and remeasurement) under the defined benefit retirement benefit plans are determined using the projected unit credit method. Service cost (including current service cost and gains or losses on settlements) and net interest on the net defined benefit liability (asset) are recognized as employee benefits expense in the period they occur. Remeasurement, comprising (a) actuarial gains and losses; and (b) the return on plan assets, excluding amounts included in net interest on the net defined benefit liability (asset), is recognized in other comprehensive income in the period in which they occur. Remeasurement recognized in other comprehensive income is reflected immediately in retained earnings and will not be reclassified to profit or loss.

Net defined benefit liability (asset) represents the actual deficit (surplus) in the Company's defined benefit plan. Any surplus resulting from this calculation is limited to the present value of any refunds from the plans or reductions in future contributions to the plans.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Other long-term employee benefits

Other long-term employee benefits are accounted for in the same way as the accounting required for defined benefit plan except that remeasurement is recognized in profit or loss.

**Income Tax** 

Income tax expense represents the sum of the tax currently payable and deferred tax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Current tax

According to the Income Tax Act in the ROC, an additional tax of unappropriated earnings is provided for in the year the stockholders approve to retain the earnings.

Adjustments of prior years' tax liabilities are added to or deducted from the current year's tax provision.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Deferred tax

Deferred tax is recognized on temporary differences between the carrying amounts of assets and liabilities in the Company's financial statements and the corresponding tax bases used in the computation of taxable profit.

Deferred tax liabilities are generally recognized for all taxable temporary differences. Deferred tax assets are generally recognized for all deductible temporary differences and unused tax credits from purchases of machinery, equipment and technology, and research and development expenditures, etc. to the extent that it is probable that taxable profits will be available against which those deductible temporary differences can be utilized.

Deferred tax liabilities are recognized for taxable temporary differences associated with investments in subsidiaries, associates and joint ventures, except where the Company is able to control the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax assets arising from deductible temporary differences associated with such investments and interests are only recognized to the extent that it is probable that there will be sufficient taxable profits against which to utilize the benefits of the temporary differences and they are expected to reverse in the foreseeable future.

The carrying amount of deferred tax assets is reviewed at the end of each reporting period and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. A previously unrecognized deferred tax asset is also reviewed at the end of each reporting period and recognized to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax assets and liabilities reflects the tax consequences that would follow from the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Current and deferred tax

Current and deferred tax are recognized in profit or loss, except when they relate to items that are recognized in other comprehensive income, in which case, the current and deferred tax are also recognized in other comprehensive income.

------

Where current tax or deferred tax arises from the initial accounting for the acquisition of a subsidiary, the tax effect is included in the accounting for the investments in a subsidiary.

**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Material accounting judgments

1) Principal versus agent

The Company's project agreements are mainly to provide one or more customized equipment or services to customers. In order to fulfill the agreements, another party may be involved in some agreements. The Company considers the following factors to determine whether the Company is a principal of the transaction: whether the Company is the primary obligation provider of the agreements, its exposures to inventory risks and the discretion in establishing prices, etc. The determination of whether the Company is a principal or an agent will affect the amount of revenue recognized by the Company. Only when the Company is acting as a principal, gross inflows of economic benefits arising from transactions is recognized as revenue.

2) Control over subsidiaries

As discussed in Note 14, some entities are subsidiaries of the Company although the Company only owns less than 50% ownership interests in these entities. After considering the Company's absolute size of holding in the entity and the relative size of and the dispersion of shares owned by the other stockholders, and the contractual arrangements between the Company and other investors, potential voting interests and the written agreement between stockholders, the management concluded that the Company has a sufficiently dominant voting interest to direct the relevant activities of the entity and therefore the Company has control over these entities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Key sources of estimation uncertainty and assumption

The following are the key assumptions concerning the future, and other key sources of estimation uncertainty at the end of the reporting period. Actual results may differ from these estimates.

1) Impairment of trade notes and accounts receivable

The provision for impairment of trade notes and accounts receivable is based on assumptions on probability of default and expected credit loss rates. The Company uses judgment in making these assumptions and in selecting the inputs to the impairment calculation, based on the Company's past experience, current market conditions as well as forward looking information at the end of each reporting period. For details of the key assumptions and inputs used, see Note 10. Where the actual future cash flows are less than expected, a material impairment loss may arise.

2) Fair value measurements and valuation processes

For the assets and liabilities measured at fair value without quoted prices in active markets, the Company's management determines the appropriate valuation techniques for the fair value measurements and whether to engage third party qualified appraisers based on the related regulations and professional judgments.

Information about the valuation techniques and inputs used in determining the fair value of various assets and liabilities was disclosed in Note 33. If the actual changes of inputs in the future differ from expectation, the fair value may vary accordingly. The Company updates inputs periodically to monitor the appropriateness of the fair value measurement.

3) Provision for inventory valuation and obsolescence

Inventories are stated at the lower of cost or net realizable value. Net realizable value is calculated as the estimated selling price less the estimated costs necessary to make a sale. Comparison of net realizable value and cost is determined on an item by item basis, except for those similar items which could be categorized into the same groups. The Company uses the inventory holding period and turnover as the evaluation basis for inventory obsolescence losses.

4) Impairment of property, plant and equipment, right-of-use assets, investment properties and intangible assets

When an indication of impairment is assessed with objective evidence, the Company considers whether the recoverable amount of an asset is less than its carrying amount and recognizes the impairment loss based on difference between the recoverable amount and its carrying amount. The estimate of recoverable amount would impact on the timing and the amount of impairment loss recognition.

5) Useful lives of property, plant and equipment

As discussed in Note 3, "Summary of Material Accounting Policy Information—Property, Plant and Equipment", the Company reviews estimated useful lives of property, plant and equipment at the end of each year.

6) Recognition and measurement of defined benefit plans

Net defined benefit liabilities (assets) and the resulting pension expense under defined benefit pension plans are calculated using the Projected Unit Credit Method. Actuarial assumptions comprise the discount rate, employee turnover rate, average future salary increase and etc. Changes in economic circumstances and market conditions will affect these assumptions and may have a material impact on the amount of the expense and the liability.

7) Lessees' incremental borrowing rates

In determining a lessee's incremental borrowing rate used in discounting lease payments, a risk-free rate for relevant duration and the same currency is selected as a reference rate. The lessee's credit spread adjustments and lease specific adjustments are also taken into account.

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 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 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.

The Company's provision matrix arising from telecommunications business and project business is disclosed below.

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 30 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 the Company 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 34 for details.

Other financial assets - noncurrent was Piping Fund. As part of the government's effort to upgrade the existing telecommunications infrastructure, the Company 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.

**20.** **HEDGING FINANCIAL INSTRUMENTS** 

The Company'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, the Company'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.

The Company 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.

**25.** **RETIREMENT BENEFIT PLANS** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Defined contribution plans

The pension plan under the Labor Pension Act of ROC (the "LPA") is considered as a defined contribution plan. Based on the LPA, the Company makes monthly contributions to employees' individual pension accounts at 6% of monthly salaries and wages.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Defined benefit plans

The Company completed its privatization plans on August 12, 2005. The Company is required to pay all accrued pension obligations including service clearance payment, lump sum payment under civil service plan, additional separation payments, etc. upon the completion of the privatization in accordance with the Statute Governing Privatization of Stated-owned Enterprises. After paying all pension obligations for privatization, the plan assets of the Company should be transferred to the Fund for Privatization of Government-owned Enterprises (the "Privatization Fund") under the Executive Yuan. On August 7, 2006, the Company transferred the remaining balance of fund to the Privatization Fund. However, according to the instructions of MOTC, the Company was requested to administer the distributions to employees for pension obligations including service clearance payment, lump sum payment under civil service plan, additional separation payments, etc. upon the completion of the privatization and recognized in other current monetary assets.

------

The Company with the pension mechanism under the Labor Standards Law in the ROC is considered as defined benefit plans. These pension plans provide benefits based on an employee's length of service and average six-month salary prior to retirement. The Company contributes an amount no more than 15% of salaries paid each month to their respective pension funds (the Funds), which are administered by the Labor Pension Fund Supervisory Committee (the Committee) and deposited in the names of the Committees in the Bank of Taiwan. The plan assets are held in a commingled fund which is operated and managed by the government's designated authorities; as such, the Company does not have any right to intervene in the investments of the funds. According to the Article 56 of the Labor Standards Law, entities are required to contribute the difference in one appropriation to their pension funds before the end of next March when the balance of the Funds is insufficient to pay the eligible employees who meet the retirement criteria in the following year.

The amounts included in the balance sheets arising from the Company's obligation in respect of its defined benefit plans were as follows:

Relevant pension costs recognized in profit and loss for defined benefit plans were as follows:

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31** | **Year Ended December 31** |
|  | **2025** | **2024** |

|  Research and development expenses | 28744 | 32489 |
|  | $663836 | $834582 |

---

The Company is exposed to following risks for the defined benefits plans under the Labor Standards Law:

a. Investment risk

Under the Labor Standards Law, the rate of return on assets shall not be lower than the average interest rate on a two-year time deposit published by the local banks and the government is responsible for any shortfall in the event that the rate of return is less than the required rate of return. The plan assets are held in a commingled fund mainly invested in foreign and domestic equity and debt securities and bank deposits which is operated and managed by the government's designated authorities; as such, the Company does not have any right to intervene in the investments of the funds.

------

b. Interest rate risk

The decline in government bond interest rate will increase the present value of the obligation on the defined benefit plan, while the return on plan assets will increase. The net effect on the present value of the obligation on defined benefit plan is partially offset by the return on plan assets.

c. Salary risk

The calculation of the present value of defined benefit obligation is referred to the plan participants' future salary. Hence, the increase in plan participants' salary will increase the present value of the defined benefit obligation.

The most recent actuarial valuation of plan assets and the present value of the defined benefit obligation were carried out by the independent actuary. The principal assumptions used for the purpose of the actuarial valuations were as follows:

---

| | | |
|:---|:---|:---|
|  | **Measurement Date** | **Measurement Date** |
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  Discount rates | 1.50% | 1.75% |
|  Expected rates of salary increase | 2.50% | 2.25% |

---

If reasonably possible changes of the respective significant actuarial assumptions occur at the end of reporting periods, while holding all other assumptions constant, the present values of the defined benefit obligations would increase (decrease) as follows:

---

| | | |
|:---|:---|:---|
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  Discount rates |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.5% increase | $(713371) | $(780047) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.5% decrease | $879350 | $825198 |
|  Expected rates of salary increase |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.5% increase | $946085 | $893483 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.5% decrease | $(781802) | $(852079) |

---

The sensitivity analysis presented above may not be representative of the actual change in the present value of the defined benefit obligation as it is unlikely that the change in assumptions would occur in isolation of one another as some of the assumptions may be correlated. There is no change in the methods and assumptions used in preparing the sensitivity analysis from the previous period.

|:---|:---|:---|
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  The expected contributions to the plan for the next year | $1091519 | $1219330 |
|  The average duration of the defined benefit obligation | 6.5 years | 6.0 years |

As of December 31, 2025, the Company's maturity analysis of the undiscounted benefit payments was as follows:

---

| | |
|:---|:---|
| **Year** | **Amount** |
| 2026 | $2373745 |
| 2027 | 3916262 |

Additional paid-in capital from share premium, donated capital and the difference between 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, which however is limited to a certain percentage of the Company'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.

------

c. Retained earnings and dividends policy

In accordance with the the Company's Articles of Incorporation, the Company 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 the Company'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 the Company. This reserve can only be used to offset a deficit, or, when the legal reserve has exceeded 25% of the Company's paid-in capital, the excess may be transferred to capital or distributed in cash.

(Concluded)

The Board of Directors of the Company resolved to sign a joint construction with separate sale and partition contract for the Datong S. Sec., Sanchong Dist., New Taipei City project with LED in August 2021. The Company classified the land of the project as investment properties. Regarding the project, the Company has signed the house and land presale contracts with customers and has received payments in accordance with the contracts. Please refer to Note 36 for details.

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. Significant changes of contract assets and liabilities recognized resulting from product and service bundling were as follows:

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31** | **Year Ended December 31** |
|  | **2025** | **2024** |
|  Contract assets |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Net increase of customer contracts | $3162490 | $3291980 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Reclassified to trade receivables | (3006542) | (2864384) |
|  | $155948 | $427596 |
|  Contract liabilities |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Net increase of customer contracts | $77628 | $67512 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Recognized as revenues | (82196) | (70680) |
|  | $(4568) | $(3168) |

---

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.

------

Revenue recognized for the year that was included in the contract liability at the beginning of the year was as follows:

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31** | **Year Ended December 31** |

---

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 telecommunications service contracts are expected to be recoverable; therefore, such costs were capitalized. Amortization expenses for the years ended December 31, 2025 and 2024 were $6,998,153 thousand and $6,730,872 thousand, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. Remaining Performance Obligations

As of December 31, 2025, the aggregate amount of transaction price allocated to performance obligations for non-cancellable telecommunications service contracts that are unsatisfied is $52,297,792 thousand. The Company recognizes revenue when service is provided over contract terms. The Company expects to recognize such revenue of $30,067,246 thousand, $16,161,159 thousand and $6,069,387 thousand in 2026, 2027 and 2028, respectively. The variable consideration collected from customers on nonrecurring basis resulting from exceeded usage from monthly fee and revenue recognized for contracts that the Company has a right to consideration from customers in the amount corresponding directly with the value to the customers of the Company's performance completed to date have been excluded from the disclosure of remaining performance obligations.

As of December 31, 2025, the aggregate amount of transaction price allocated to performance obligations for non-cancellable project business contracts that are unsatisfied is $34,357,614 thousand. The Company recognizes revenues when the project business contract is completed and accepted by customers. The Company expects to recognize such revenue of $17,950,159 thousand, $9,439,733 thousand and $6,967,722 thousand in 2026, 2027 and 2028, respectively. Project business contracts whose expected duration are less than a year have been excluded from the aforementioned disclosure.

**32.** **CAPITAL MANAGEMENT** 

The Company manages its capital to ensure that 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 and the equity of the Company.

The Company is 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.

**33.** **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.

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.

---

| | | |
|:---|:---|:---|
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  Discount for lack of marketability | 10.00%~20.00% | 20.00% |
|  Noncontrolling interests discount | 10.00%~25.00% | 15.00%~25.00% |
|  Growth rate of long-term revenue | 1.33% | 0.12% |
|  Discount rate | 8.21%~11.60% | 8.32%~14.40% |

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 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.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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 38 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:

---

| | | |
|:---|:---|:---|
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  Assets |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; EUR | $6408 | $1160 |
|  Liabilities |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; EUR | 56 | 1907 |

---

<u>Foreign currency sensitivity analysis</u>

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

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.

------

| | | |
|:---|:---|:---|
|  | **Year Ended December 31** | **Year Ended December 31** |
|  | **2025** | **2024** |
|  Profit or loss |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Monetary assets and liabilities (a) |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; USD | $60069 | $12854 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; EUR | (70561) | (49238) |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; EUR | 7380 | 17070 |

---

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

b) This is mainly attributable to forward exchange contracts.

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:

---

| | | |
|:---|:---|:---|
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  Fair value interest rate risk |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Financial assets | $32357508 | $40233358 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Financial liabilities | 35207058 | 40528553 |
|  Cash flow interest rate risk |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Financial assets | 10828566 | 5565363 |

<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 $27,071 thousand and $13,913 thousand for the years ended December 31, 2025 and 2024, respectively. This is mainly attributable to the Company's exposure to floating interest rates on its financial assets.

------

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 $53,012 thousand and $317,091 thousand, respectively, as a result of the changes in fair value of financial assets at FVTPL and financial assets at FVOCI for the year ended December 31, 2025. If equity prices had been 5% higher/lower, pre-tax profit and pre-tax other comprehensive income would have increased/decreased by $46,040 thousand and $222,333 thousand, respectively, as a result of the changes in fair value of financial assets at FVTPL and financial assets at FVOCI for the year ended December 31, 2024.

&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 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.

**INDEPENDENT AUDITORS' REPORT** 

PWCR25003503

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

**Opinion** 

We have audited the accompanying consolidated balance sheets of Chunghwa Telecom Co., Ltd. and its subsidiaries (the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of comprehensive income, of changes in equity and of cash flows for the years then ended, and notes to the consolidated financial statements, including a summary of material accounting policy information.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2025 and 2024, and its consolidated financial performance and its consolidated cash flows for the years then ended in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and the International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretations that came into effect as endorsed by the Financial Supervisory Commission.

**Basis for opinion** 

We conducted our audits in accordance with the Regulations Governing Financial Statement Audit and Attestation Engagements of Certified Public Accountants and Standards on Auditing of the Republic of China. Our responsibilities under those standards are further described in the Auditors' responsibilities for the audit of the consolidated financial statements section of our report. We are independent of the Company in accordance with the Norm of Professional Ethics for Certified Public Accountant of the Republic of China, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

**Key audit matters** 

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the Company's 2025 consolidated financial statements. These matters were addressed in the context of our audit of the consolidated financial statements as a whole and, in forming our opinion thereon, we do not provide a separate opinion on these matters.

Key audit matters for the Company's 2025 consolidated financial statements are stated as follows:

**Accuracy of revenues from mobile services, fixed-line broadband services and fixed-line data services** 

<u>Description</u> 

Refer to Note 3 for the accounting policies on revenue recognition and Notes 30 and 44 for details of revenue.

------

The Company recognizes revenues from mobile services, fixed-line broadband services and fixed-line data services based on the terms of mobile services, fixed-line broadband services and fixed-line data services contracts and actual usage of mobile services, fixed-line broadband services and fixed-line data services. Given that revenues from mobile services, fixed-line broadband services and fixed-line data services are comprised of a high volume of low-dollar transactions from a large number of contracts and a wide variety of tariff plans, the Company highly relies on the automated information systems to process and recognize revenues from mobile services, fixed-line broadband services and fixed-line data services.

Given the Company's revenues from mobile services, fixed-line broadband services and fixed-line data services are comprised of a high volume of low-dollar transactions and highly relies on information technology systems, a high degree of auditor effort was required in performing procedures related to accuracy of the Company's revenues from mobile services, fixed-line broadband services and fixed-line data services. Thus, we consider the accuracy of revenues from mobile services, fixed-line broadband services and fixed-line data services as a key audit matter.

<u>How our audit addressed the matter</u> 

Our audit procedures performed in respect of the above included the following:

1. Obtained an understanding over the design of internal controls and information systems related to the business
process of the Company's revenue recognition on mobile services, fixed-line broadband services and fixed-line data services and evaluated operating effectiveness of such controls. This includes the following procedures:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Obtained an understanding and evaluated the significant systems related to revenues from mobile services,
fixed-line broadband services and fixed-line data services, and tested the information technology general controls as well as the automated controls for automatic calculations and system interface over these systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Tested manual controls related to the review of information on mobile services, fixed-line broadband services and
fixed-line data services, including service acceptance, updates to price information, data collection and system interface, pricing, billing, and accounting processes.

2. Selected samples from mobile services, fixed-line broadband services and fixed-line data services revenues,
agreed the samples selected to service contracts, invoices, payment records, and tested consistency between the data entered into the system and the original service contracts.

**Other matter – Parent company only financial reports** 

We have audited and expressed an unmodified opinion on the parent company only financial statements of Chunghwa Telecom Co., Ltd. as of and for the years ended December 31, 2025 and 2024.

**Responsibilities of management and those charged with governance for the consolidated financial statements** 

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and the International Financial Reporting Standards, International Accounting Standards, IFRIC Interpretations, and SIC Interpretations that came into effect as endorsed by the Financial Supervisory Commission, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

------

In preparing the consolidated financial statements, management is responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

Those charged with governance, including the audit committee, are responsible for overseeing the Company's financial reporting process.

**Auditors' responsibilities for the audit of the consolidated financial statements** 

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors' report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the Standards on Auditing of the Republic of China will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with the Standards on Auditing of the Republic of China, we exercise professional judgment and professional skepticism throughout the audit. We also:

1. Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to
fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is
higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

2. Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control.

3. Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and
related disclosures made by management.

4. Conclude on the appropriateness of management's use of the going concern basis of accounting and, based
on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company's ability to continue as a going concern. If we conclude that a material uncertainty exists,
we are required to draw attention in our auditors' report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence
obtained up to the date of our auditors' report. However, future events or conditions may cause the Company to cease to continue as a going concern.

5. Evaluate the overall presentation, structure and content of the consolidated financial statements, including
the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

------

6. Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business
activities within the Company to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the consolidated financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditors' report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

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

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS** 

**YEARS ENDED DECEMBER 31, 2025 AND 2024** 

**(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 February 26, 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 Financial Reporting Standards (IFRS), International Accounting Standards (IAS), International Financial Reporting Interpretations Committee (IFRIC) and SIC Interpretations (SIC) (collectively, the "IFRSs") endorsed and issued into effect by the Financial Supervisory Commission (the "FSC") (collectively, the "Taiwan-IFRS").

------

**Basis of Preparation** 

The consolidated financial statements have been prepared on the historical cost basis except for certain financial instruments that are measured at fair values and net defined benefit liabilities (assets) which are measured at the present value of the defined benefit obligations less the fair value of plan assets.

**Current and Noncurrent Assets and Liabilities** 

Current assets include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Assets held primarily for the purpose of trading;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Assets expected to be realized within twelve months after the reporting period; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Cash and cash equivalents unless the asset is restricted from being exchanged or used to settle a liability for
at least twelve months after the reporting period.

Current liabilities include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Liabilities held primarily for the purpose of trading;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Liabilities due to be settled within twelve months after the reporting period; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Liabilities for which the Company on the balance sheet date does not have in substance the right to defer
settlement for at least twelve months after the reporting period.

Assets and liabilities that are not classified as current are classified as noncurrent.

Light Era Development Co., Ltd. ("LED") engages mainly in development of property for rent and sale. The assets and liabilities of LED related to property development within its operating cycle, which is over one year, are classified as current items.

**Basis of Consolidation** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Principles for preparing consolidated financial statements

The consolidated financial statements incorporate the financial statements of Chunghwa and entities controlled by Chunghwa (its subsidiaries).

When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies in line with those used by the Company.

All inter-company transactions, balances, income and expenses are eliminated in full upon consolidation.

<u>Attribution of total comprehensive income to noncontrolling interests</u>

Total comprehensive income of subsidiaries is attributed to the stockholders of the parent and to the noncontrolling interests even if it results in the noncontrolling interests having a deficit balance.

<u>Changes in the Company's ownership interests in subsidiaries</u>

Changes in the Company's ownership interests in subsidiaries that do not result in the Company losing control over the subsidiaries are accounted for as equity transactions. The carrying amounts of the Company's interests and the noncontrolling interests are adjusted to reflect the changes in their relative interests in the subsidiaries. Any difference between the amount by which the noncontrolling interests are adjusted and the fair value of the consideration paid or received is recognized directly in equity and attributed to stockholders of the parent.

------

<u>Loss of control of subsidiaries</u>

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. The subsidiaries in the consolidated financial statements

The detail information of the subsidiaries at the end of reporting period was as follows:

(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 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 2025, respectively.

c) 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.

d) CLPT issued new shares in July 2024 and December 2025 as its employees exercised options. Therefore, the
Company's ownership interest in CLPT decreased to 69.87% and 62.03% as of December 31, 2024 and 2025, respectively.

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 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
63.45% and 56.69% as of December 31, 2024 and 2025, 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. 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. Therefore, the Company's ownership interest in IISI decreased to 49.64% and 44.53% as of December 31, 2024 and 2025, respectively. 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 and established CDCC Capital in February 2024. Chunghwa obtained 100% ownership interest of
CDCC Capital.

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

i) Chunghwa invested and established CHAI in October 2025. Chunghwa obtained 100% ownership interest of CHAI.

j) 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.

k) 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.

l) 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 December 31, 2025.

![LOGO](g67626dsp0133.jpg)

**Foreign Currencies** 

In preparing the financial statements of each individual entity, transactions in currencies other than the entity's functional currency (foreign currencies) are recognized at the rates of exchange prevailing at the dates of the transactions.

------

At the end of each reporting period, monetary items denominated in foreign currencies are retranslated at the rates prevailing at that date. Exchange differences on monetary items arising from settlement or translation are recognized in profit or loss in the period in which they arise.

Non-monetary items carried at fair value that are denominated in foreign currencies are retranslated at the rates prevailing at the date when the fair value was determined and related exchange differences are recognized in profit or loss. Conversely, when the fair value changes were recognized in other comprehensive income, related exchange difference shall be recognized in other comprehensive income.

Non-monetary items that are measured at historical cost in a foreign currency are not retranslated.

For the purpose of presenting consolidated financial statements, the assets and liabilities of the Company's foreign operations (including those subsidiaries, associates and joint ventures in other countries or currencies used different with Chunghwa) are translated into New Taiwan dollars using exchange rates prevailing at the end of each reporting period. Income and expense items are translated at the average exchange rates for the period. Exchange differences arising, if any, are recognized in other comprehensive income and attributed to stockholders of the parent and noncontrolling interests as appropriate.

**Cash Equivalents** 

Cash equivalents include those maturities within three months from the date of acquisition, highly liquid, readily convertible to a known amount of cash and are subject to an insignificant risk of changes in value such as commercial paper, negotiable certificates of deposit, time deposits and stimulus vouchers. These cash equivalents are held for the purpose of meeting short-term cash commitments.

**Inventories** 

Inventories are stated at the lower of cost or net realizable value item by item, except for those that may be appropriate to group items of similar or related inventories. Net realizable value is the estimated selling price of inventories less all estimated costs of completion and costs necessary to make the sale. The calculation of the cost of inventory is derived using the weighted-average method.

**Buildings and Land Consigned to Construction Contractors** 

Inventories of LED are stated at the lower of cost or net realizable value item by item, except for those that may be appropriate to group as similar items or related inventories. Land acquired before construction is classified as land held for development and then reclassified as land held under development after LED begins its construction project.

Upon the completion of the construction project, LED recognizes revenues in the amount of proceeds from customers for land and buildings and related costs when ownership is transferred to the customers. The unsold portion of the completed construction project is transferred to land and building held for sale.

**Investments in Associates and Joint Ventures** 

An associate is an entity over which the Company has significant influence and that is neither a subsidiary nor an interest in a joint venture. A joint venture is a joint arrangement whereby the Company and other parties that have joint control of the arrangement have rights to the net assets of the arrangement.

Investments accounted for using the equity method include investments in associates and interests in joint ventures. Under the equity method, an investment in an associate and a joint venture is initially recognized at cost and adjusted thereafter to recognize the Company's share of profit or loss and other comprehensive income of the associate and joint venture as well as the distribution received. The Company also recognizes its share in changes in the associates and joint ventures.

------

When the Company subscribes for new shares of an associate and a joint venture at a percentage different from its existing ownership percentage, the resulting carrying amount of the investment differs from the amount of the Company's proportionate interest in the associate and joint venture. The Company records such a difference as an adjustment to investments with the corresponding amount charged or credited to additional paid-in capital. When the adjustment should be debited to additional paid-in capital but the additional paid-in capital recognized from investments accounted for using equity method is insufficient, the shortage is debited to retained earnings.

Any excess of the cost of acquisition over the Company's share of the fair value of the identifiable net assets and liabilities of an associate and a joint venture at the date of acquisition is recognized as goodwill, which is included within the carrying amount of the investment and shall not be amortized. Any excess of the Company's share of the net fair value of the identifiable assets and liabilities over the cost of acquisition is recognized immediately in profit or loss.

The entire carrying amount of an investment (including goodwill) is tested for impairment as a single asset by comparing its recoverable amount with its carrying amount. Any impairment loss recognized is not allocated to any asset, including goodwill, that forms part of the carrying amount of the investment. Any reversal of that impairment loss is recognized to the extent that the recoverable amount of the investment subsequently increases.

The Company discontinues the use of the equity method from the date on which its investment ceases to be an associate and a joint venture. Any retained investment is measured at fair value at that date, and the fair value is regarded as the investment's fair value on initial recognition as a financial asset. The difference between the previous carrying amount of the associate and joint venture attributable to the retained interest and its fair value is included in the determination of the gain or loss on disposal of the associate and joint venture. The Company accounts for all amounts previously recognized in other comprehensive income in relation to that associate and joint venture on the same basis as would be required had that associate and joint venture directly disposed of the related assets or liabilities.

When the Company transacts with its associate and joint venture, profits and losses resulting from the transactions with the associate and joint venture are recognized in the Company's consolidated financial statements only to the extent of interests in the associate and joint venture that are not related to the Company.

**Property, Plant and Equipment** 

Property, plant and equipment are initially measured at cost and subsequently measured at cost less accumulated depreciation and accumulated impairment loss.

Property, plant and equipment in the course of construction are depreciated and classified to the appropriate categories of property, plant and equipment when completed and ready for their intended use.

Depreciation on property, plant and equipment is recognized using the straight-line method. Each significant part is depreciated separately. Freehold land is not depreciated. The estimated useful lives, residual values and depreciation method are reviewed at the end of each year, with the effect of any changes in estimate accounted for on a prospective basis.

On derecognition of an item of property, plant and equipment, the difference between the net disposal proceeds and the carrying amount of the asset is recognized in profit or loss in the period in which the property is derecognized.

------

**Investment Properties** 

Investment properties are properties held to earn rentals and/or for capital appreciation. Investment properties also include land held for a currently undetermined future use.

Investment properties are measured initially at cost, including transaction costs. Subsequent to initial recognition, investment properties are measured at cost less accumulated depreciation and accumulated impairment loss. Depreciation is recognized using the straight-line method.

For a transfer from the investment properties to property, plant and equipment, the deemed cost of the property, plant and equipment for subsequent accounting is its carrying amount at the commencement of owner-occupation.

For a transfer from the property, plant and equipment to investment properties, the deemed cost of the investment properties for subsequent accounting is its carrying amount at the end of owner-occupation.

On derecognition of the investment properties, the difference between the net disposal proceeds and the carrying amount of the asset is recognized in profit or loss in the period in which the property is derecognized.

**Goodwill** 

Goodwill arising from the acquisition of a business is carried at cost as established at the date of acquisition of the business less accumulated impairment loss.

For the purpose of impairment testing, goodwill is allocated to each of the Company's cash-generating units or groups of cash-generating units (referred to as "cash-generating unit") that are expected to benefit from the synergies of the business combination.

A cash-generating unit to which goodwill has been allocated is tested for impairment annually, or more frequently when there is an indication that the unit may be impaired, by comparing its carrying amount, including the attributable goodwill, with its recoverable amount. However, if the goodwill allocated to a cash-generating unit was acquired in a business combination during the current annual period, that unit shall be tested for impairment before the end of the current annual period. If the recoverable amount of the cash-generating unit is less than its carrying amount, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro rata based on the carrying amount of each asset in the unit. Any impairment loss is recognized directly in profit or loss. An impairment loss recognized for goodwill is not reversed in subsequent periods.

**Intangible Assets Other Than Goodwill** 

Intangible assets with finite useful lives that are acquired separately are initially measured at cost and subsequently measured at cost less accumulated amortization and accumulated impairment loss. Amortization is recognized on a straight-line basis. The estimated useful life, residual value, and amortization method are reviewed at the end of each reporting period, with the effect of any changes in estimate being accounted for on a prospective basis. The residual value of an intangible asset with a finite useful life shall be assumed to be zero unless the Company expects to dispose of the intangible asset before the end of its economic life. Intangible assets with indefinite useful lives are measured at cost less accumulated impairment loss.

Intangible assets acquired in a business combination and recognized separately from goodwill are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Subsequent to initial recognition, they are measured on the same basis as intangible assets that are acquired separately.

------

Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in profit or loss in the period in which the asset is derecognized.

**Impairment of Property, Plant and Equipment, Right-of-use Assets, Investment Properties, Intangible Assets Other Than Goodwill and Incremental Costs of Obtaining Contracts** 

At the end of each reporting period, the Company reviews the carrying amounts of its property, plant and equipment, right-of-use assets, investment properties and intangible assets, excluding goodwill, to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss. When it is not possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the cash-generating unit to which the asset belongs.

Intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment at least annually and whenever there is an indication that the assets may be impaired.

Recoverable amount is the higher of fair value less costs to sell and value in use. If the recoverable amount of an asset or cash-generating unit is estimated to be less than its carrying amount, the carrying amount of the asset or cash-generating unit is reduced to its recoverable amount, with the resulting impairment loss recognized in profit or loss.

Impairment loss from the assets related to incremental cost of obtaining contracts is recognized to the extent that the carrying amount of the assets exceeds the remaining amount of consideration that the Company expects to receive in exchange for related goods or services less the costs which relate directly to providing those goods or services.

When an impairment loss is subsequently reversed, the carrying amount of the asset or cash-generating unit is increased to the revised estimate of its recoverable amount, but only to the extent of the carrying amount that would have been determined had no impairment loss been recognized for the asset or cash-generating unit in prior years. A reversal of an impairment loss is recognized in profit or loss.

**Financial Instruments** 

Financial assets and financial liabilities are recognized when the Company becomes a party to the contractual provisions of the instruments.

Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition of financial assets and financial liabilities (other than financial assets and financial liabilities at fair value through profit or loss) are added to the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at fair value through profit or loss are recognized immediately in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Financial assets

All regular way purchases or sales of financial assets are recognized and derecognized on a trade date basis.

1) Measurement category

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a) Financial assets at fair value through profit or loss (FVTPL)

Financial asset is classified as at FVTPL when the financial asset is mandatorily classified as at FVTPL. Financial assets mandatorily classified as at FVTPL include investments in equity instruments which are not designated as at fair value through other comprehensive income (FVOCI).

------

Financial assets at FVTPL are stated at fair value, with any gains or losses arising on remeasurement recognized in profit or loss. The net gain or loss recognized in profit or loss does not incorporate any dividend earned on the financial asset. Fair value is determined in the manner described in Note 37.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b) Financial assets at amortized cost

Financial assets that meet the following conditions are subsequently measured at amortized cost:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i. The financial asset is held within a business model whose objective is to hold financial assets in order to
collect contractual cash flows; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii. The contractual terms of the financial asset give rise on specified dates to cash flows that are solely
payments of principal and interest on the principal amount outstanding.

Subsequent to initial recognition, financial assets at amortized cost are measured at amortized cost, which equals to gross carrying amount determined by the effective interest method less any impairment loss, except for short-term receivables as the effect of discounting is immaterial. Exchange differences are recognized in profit or loss.

Interest income is calculated by applying the effective interest rate to the gross carrying amount of such financial assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c) Investments in equity instruments at FVOCI

On initial recognition, the Company may make an irrevocable election to designate investments in equity instruments as at FVOCI. Designation at FVOCI is not permitted if the equity investment is held for trading or if it is contingent consideration recognized by an acquirer in a business combination.

Investments in equity instruments at FVOCI are subsequently measured at fair value with gains and losses arising from changes in fair value recognized in other comprehensive income and accumulated in other equity. The cumulative gain or loss will not be reclassified to profit or loss on disposal of the equity investments. Instead, it will be transferred to retained earnings.

Dividends on these investments in equity instruments are recognized in profit or loss when the Company's right to receive the dividends is established, unless the dividends clearly represent a recovery of part of the cost of the investment.

2) Impairment of financial assets and contract assets

The Company recognizes a loss allowance for expected credit losses on financial assets at amortized cost (including accounts receivable) and contract assets.

The Company recognizes lifetime Expected Credit Loss (ECL) for accounts receivable and contract assets. For all other financial instruments, the Company recognizes lifetime ECL when there has been a significant increase in credit risk since initial recognition. If, on the other hand, the credit risk on the financial instrument has not increased significantly since initial recognition, the Company measures the loss allowance for that financial instrument at an amount equal to 12-month ECL.

------

Expected credit losses reflect the weighted average of credit losses with the respective risks of a default occurring as the weights. Lifetime ECL represents the expected credit losses that will result from all possible default events over the expected life of a financial instrument. In contrast, 12-month ECL represents the portion of ECL that is expected to result from default events on a financial instrument that are possible within 12 months after the reporting date.

The Company recognizes an impairment loss for all financial instruments with a corresponding adjustment to their carrying amount through a loss allowance account.

3) Derecognition of financial assets

The Company derecognizes a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another entity.

On derecognition of a financial asset at amortized cost in its entirety, the difference between the asset's carrying amount and the sum of the consideration received and receivable is recognized in profit or loss.

On derecognition of investments in equity instruments at FVOCI in its entirety, the cumulative gain or loss is directly transferred to retained earnings, and it is not reclassified to profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Financial liabilities

1) Subsequent measurement

Except for financial liabilities at FVTPL, all the financial liabilities are subsequently measured at amortized cost using the effective interest method.

2) Derecognition of financial liabilities

The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable, including any non-cash assets transferred or liabilities assumed, is recognized in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Derivative financial instruments

The Company enters into derivative financial instruments to manage its exposure to foreign exchange rate risks, including forward exchange contracts.

Derivatives are initially measured at fair value at the date the derivative contracts are entered into and are subsequently remeasured to their fair value at the end of each reporting period. The resulting gain or loss is recognized in profit or loss immediately unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship. When the fair value of derivative financial instruments is positive, the derivative is recognized as a financial asset; when the fair value of derivative financial instruments is negative, the derivative is recognized as a financial liability.

**Hedge Accounting** 

The Company designates some derivatives instruments as cash flow hedges. Hedges of foreign exchange risk on firm commitments are accounted for as cash flow hedges.

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in profit or loss.

------

The associated gains or losses that were recognized in other comprehensive income are reclassified from equity to profit or loss as a reclassification adjustment in the line item relating to the hedged item in the same period when the hedged item affects profit or loss. If a hedge of a forecast transaction subsequently results in the recognition of a non-financial asset or a non-financial liability, the associated gains and losses that were recognized in other comprehensive income are removed from equity and are included in the initial cost of the non-financial asset or non-financial liability.

The Company discontinues hedge accounting only when the hedging relationship ceases to meet the qualifying criteria; for instance, when the hedging instrument expires or is sold, terminated or exercised. The cumulative gain or loss on the hedging instrument that has been previously recognized in other comprehensive income from the period when the hedge was effective remains separately in equity until the forecast transaction occurs. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in equity is recognized immediately in profit or loss.

**Provisions** 

Provisions are measured at the best estimate of the expenditure required to settle the Company's obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. The provisions for warranties claims are made by management according to the sales agreements which represent the management's best estimate of the future outflow of economic benefits. The provisions of warranties claims are recognized as operating cost in the period in which the goods are sold. The provision for onerous contracts represents the present obligation resulting from the measurement for the unavoidable costs of meeting the Company's contractual obligations exceed the economic benefits expected to be received from the contracts. In assessing whether a contract is onerous, the cost of fulfilling a contract includes both the incremental costs of fulfilling that contract and an allocation of other costs that are related directly to fulfilling contracts. The provision for decommissioning liabilities is recognized in accordance with the contractual requirements. The Company bears dismantling, removing the asset and restoring the site obligations for certain handsets base stations in the future. A provision is recognized for the costs to be incurred for fulfilling these obligations.

**Revenue Recognition** 

The Company identifies the performance obligations in the contract with the customers, allocates transaction price to each performance obligation and recognizes revenue when performance obligations are satisfied.

Sales of products are recognized as revenue when the Company delivers products and the customer accepts and controls the product. Except for the consumer electronic products such as mobile devices sold in channel stores which are usually in cash sale, the Company recognizes revenues for sale of other electronic devices and corresponding trade notes and accounts receivable.

Usage revenues from fixed-line services (including local, domestic long distance and international long distance telephone services), mobile services, internet and data services, and interconnection and call transfer fees from other telecommunications companies and carriers are billed in arrears and are recognized based upon seconds or minutes of traffic processed when the services are provided in accordance with contract terms. The usage revenues and corresponding trade notes and accounts receivable are recognized monthly.

Other revenues are recognized as follows: (a) one-time subscriber connection fees (on fixed-line services) are first recognized as contract liabilities and revenues are recognized subsequently over the average expected customer service periods, (b) monthly fees (on fixed-line services, mobile, internet and data services) and related receivables are accrued monthly, and (c) prepaid services (fixed-line, mobile, internet and data services) are recognized as contract liabilities upon collection considerations from customers and are recognized as revenues subsequently based upon actual usage by customers.

------

Where the Company enters into transactions which involve both the provision of telecommunications service bundled with products such as handsets, total consideration received from products and telecommunications service in these arrangements are allocated based on their relative stand-alone selling price. The amount of sales revenue recognized for products is not limited to the amount paid by the customer for the products. When the amount of sales revenue recognized for products exceeded the amount paid by the customer for the products, the difference is recognized as contract assets. Contract assets are reclassified to accounts receivable when the amounts become collectible from customers subsequently. When the amount of sales revenue recognized for products was less than the amount paid by the customer for the products, the difference is recognized as contract liabilities and revenues are recognized subsequently when the telecommunications services are provided.

For project business contracts, if a substantial part of the Company's promise to customers is to manage and coordinate the various tasks and assume the risks of those tasks to ensure the individual goods or services are incorporated into the combined output, they are treated as a single performance obligation since the Company provides a significant integration service. The Company recognizes revenues and corresponding accounts receivable when the project business contract is completed and accepted by customers. For some project contracts, the Company does not create an asset with an alternative use to the Company and has an enforceable right to payment for performance completed to date; therefore, performance obligations are satisfied and revenues are recognized over time.

For service contracts such as maintenance and warranties, customers simultaneously receive and consume the benefits provided by the Company; thus, revenues and corresponding accounts receivable of service contracts are recognized over the related service period.

When another party is involved in providing goods or services to a customer, the Company is acting as a principal if it controls the specified good or service before that good or service is transferred to a customer; otherwise, the Company is acting as an agent. When the Company is acting as a principal, gross inflow of economic benefits arising from transactions is recognized as revenue. When the Company is acting as an agent, revenue is recognized as its share of transaction.

**Incremental Costs of Obtaining Contracts** 

Commissions and equipment subsidy related to telecommunications service as a result of obtaining contracts are recognized as an asset under the incremental costs of obtaining contracts to the extent the costs are expected to be recovered and are amortized over the contract period. However, the Company elects not to capitalize the incremental costs of obtaining contracts if the amortization period of the assets that the Company otherwise would have recognized is expected to be one year or less.

Commissions for real estate sales as a result of obtaining contracts are recognized as an asset under the incremental costs of obtaining contracts to the extent the costs are expected to be recovered and are amortized when the real estate is sold and its ownership is transferred to the customers.

**Leasing** 

At inception of a contract, the Company assesses whether the contract is, or contains, a lease.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. The Company as lessor

Rental income from operating leases is recognized on a straight-line basis over the term of the relevant lease.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. The Company as lessee

The Company recognizes right-of-use assets and lease liabilities for all leases at the commencement date of a lease, except for lease payments for low-value assets are recognized as expenses on a straight-line basis over the lease terms accounted for applying recognition exemption.

------

Right-of-use assets are initially measured at cost, which comprises the initial measurement of lease liabilities and for lease payments made at or before the commencement date. Right-of-use assets are subsequently measured at cost less accumulated depreciation and accumulated impairment losses and adjusted for any remeasurement of the lease liabilities. Right-of-use assets are presented separately on the consolidated balance sheets.

Right-of-use assets are depreciated using the straight-line basis from the commencement dates to the earlier of the end of the useful lives of the right-of-use assets or the end of the lease terms.

Lease liabilities were initially measured at the present value of the lease payments, which comprise fixed payments, in-substance fixed payments, variable lease payments which depend on an index or a rate. The lease payments are discounted using the interest rate implicit in a lease, if that rate can be readily determined. If such rate cannot be readily determined, the lessee's incremental borrowing rate is used.

Lease liabilities are subsequently measured at amortized cost using the effective interest method, with interest expense recognized over the lease terms. When there is a change in a lease term or a change in future lease payments resulting from a change in an index or a rate used to determine those payments, the Company remeasures the lease liabilities with a corresponding adjustment to the right-of-use assets. However, if the carrying amount of the right-of-use assets is reduced to zero, any remaining amount of the remeasurement is recognized in profit or loss. The Company accounts for the remeasurement of the lease liability as a result of the decrease of lease scope by decreasing the carrying amount of the right-of-use assets and recognizes in profit or loss any gain or loss on the partial or full termination of the lease. Lease liabilities are presented separately on the consolidated balance sheets.

Variable lease payments not depending on an index or a rate are recognized as expenses in the periods in which they are incurred.

**Borrowing Costs** 

All borrowing costs are recognized in profit or loss in the period in which they are incurred.

**Government Grants** 

Government grants are not recognized until there is reasonable assurance that the Company will comply with the conditions attached to government grants and that the grants will be received.

Government grants related to income are recognized in profit or loss on a systematic basis over the periods in which the Company recognizes expenses of the related costs for which the grants are intended to compensate. Specifically, government grants whose primary condition is that the Company should construct noncurrent assets are recognized as deferred revenue and transferred to profit or loss on a systematic and rational basis over the useful lives of the related assets.

Government grants that become receivable as compensation for expenses or losses already incurred are recognized in profit or loss in the period in which they become receivable.

**Employee Benefits** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Short-term employee benefits

Liabilities recognized in respect of short-term employee benefits are measured at the undiscounted amount of the benefits expected to be paid in exchange for the related service.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Retirement benefits

Payments to defined contribution retirement benefit plans are recognized as an expense when employees have rendered service entitling them to the contributions.

Defined benefit costs (including service cost, net interest and remeasurement) under the defined benefit retirement benefit plans are determined using the projected unit credit method. Service cost (including current service cost and gains or losses on settlements) and net interest on the net defined benefit liability (asset) are recognized as employee benefits expense in the period they occur. Remeasurement, comprising (a) actuarial gains and losses; and (b) the return on plan assets, excluding amounts included in net interest on the net defined benefit liability (asset), is recognized in other comprehensive income in the period in which they occur. Remeasurement recognized in other comprehensive income is reflected immediately in retained earnings and will not be reclassified to profit or loss.

Net defined benefit liability (asset) represents the actual deficit (surplus) in the Company's defined benefit plan. Any surplus resulting from this calculation is limited to the present value of any refunds from the plans or reductions in future contributions to the plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Other long-term employee benefits

Other long-term employee benefits are accounted for in the same way as the accounting required for defined benefit plan except that remeasurement is recognized in profit or loss.

**Share-based Payment Arrangements - Employee Stock Options** 

The fair value determined at the grant date of the employee share options is expensed on a straight-line basis over the vesting period, based on the Company's estimate of employee stock options that are expected to ultimately vest, with a corresponding increase in additional paid-in capital - employee stock options. If the equity instruments granted vest immediately at the grant date, expenses are recognized in full in profit or loss.

At the end of each reporting period, the Company revises its estimate of the number of employee share options expected to vest. The impact of the revision of the original estimates, if any, is recognized in profit or loss such that the cumulative expense reflects the revised estimate, with a corresponding adjustment to additional paid-in capital - employee stock options.

**Income Tax** 

Income tax expense represents the sum of the tax currently payable and deferred tax.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Current tax

Income tax payable or recoverable is based on taxable profit or loss for the period determined according to the applicable tax laws of each tax jurisdiction.

According to the Income Tax Act in the ROC, an additional tax of unappropriated earnings is provided for in the year the stockholders approve to retain the earnings.

Adjustments of prior years' tax liabilities are added to or deducted from the current year's tax provision.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Deferred tax

Deferred tax is recognized on temporary differences between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases used in the computation of taxable profit. A deferred tax liability is not recognized on taxable temporary difference arising from initial recognition of goodwill.

Deferred tax liabilities are generally recognized for all taxable temporary differences. Deferred tax assets are generally recognized for all deductible temporary differences, unused loss carry forward and unused tax credits from purchases of machinery, equipment and technology, and research and development expenditures, etc. to the extent that it is probable that taxable profits will be available against which those deductible temporary differences can be utilized.

Deferred tax liabilities are recognized for taxable temporary differences associated with investments in subsidiaries, associates, and joint ventures, except where the Company is able to control the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred tax assets arising from deductible temporary differences associated with such investments and interests are only recognized to the extent that it is probable that there will be sufficient taxable profits against which to utilize the benefits of the temporary differences and they are expected to reverse in the foreseeable future.

The carrying amount of deferred tax assets is reviewed at the end of each reporting period and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. A previously unrecognized deferred tax asset is also reviewed at the end of each reporting period and recognized to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period in which the liability is settled or the asset realized, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax assets and liabilities reflects the tax consequences that would follow from the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

The Company has applied the exception to recognizing and disclosing information about deferred tax assets and liabilities related to Pillar Two income taxes. Therefore, the Company neither recognizes nor discloses information about deferred tax assets and liabilities related to Pillar Two income taxes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Current and deferred tax

Current and deferred tax are recognized in profit or loss, except when they relate to items that are recognized in other comprehensive income, in which case, the current and deferred tax are also recognized in other comprehensive income.

Where current tax or deferred tax arises from the initial accounting for a business combination, the tax effect is included in the accounting for the business combination.

------

**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Material accounting judgments

1) Principal versus agent

The Company's project agreements are mainly to provide one or more customized equipment or services to customers. In order to fulfill the agreements, another party may be involved in some agreements. The Company considers the following factors to determine whether the Company is a principal of the transaction: whether the Company is the primary obligation provider of the agreements, its exposures to inventory risks and the discretion in establishing prices, etc. The determination of whether the Company is a principal or an agent will affect the amount of revenue recognized by the Company. Only when the Company is acting as a principal, gross inflows of economic benefits arising from transactions is recognized as revenue.

2) Control over subsidiaries

As discussed in Note 3, "Summary of Material Accounting Policy Information - Basis of Consolidation", some entities are subsidiaries of the Company although the Company only owns less than 50% ownership interests in these entities. After considering the Company's absolute size of holding in the entity and the relative size of and the dispersion of shares owned by the other stockholders, and the contractual arrangements between the Company and other investors, potential voting interests and the written agreement between stockholders, the management concluded that the Company has a sufficiently dominant voting interest to direct the relevant activities of the entity and therefore the Company has control over these entities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Key sources of estimation uncertainty and assumption

The following are the key assumptions concerning the future, and other key sources of estimation uncertainty at the end of the reporting period. Actual results may differ from these estimates.

1) Impairment of trade notes and accounts receivable

The provision for impairment of trade notes and accounts receivable is based on assumptions on probability of default and expected credit loss rates. The Company uses judgment in making these assumptions and in selecting the inputs to the impairment calculation, based on the Company's past experience, current market conditions as well as forward looking information at the end of each reporting period. For details of the key assumptions and inputs used, see Note 10. Where the actual future cash flows are less than expected, a material impairment loss may arise.

2) Fair value measurements and valuation processes

For the assets and liabilities measured at fair value without quoted prices in active markets, the Company's management determines the appropriate valuation techniques for the fair value measurements and whether to engage third party qualified appraisers based on the related regulations and professional judgments.

------

Information about the valuation techniques and inputs used in determining the fair value of various assets and liabilities was disclosed in Note 37. If the actual changes of inputs in the future differ from expectation, the fair value may vary accordingly. The Company updates inputs periodically to monitor the appropriateness of the fair value measurement.

3) Provision for inventory valuation and obsolescence

Inventories are stated at the lower of cost or net realizable value. Net realizable value is calculated as the estimated selling price less the estimated costs necessary to make a sale. Comparison of net realizable value and cost is determined on an item by item basis, except for those similar items which could be categorized into the same groups. The Company uses the inventory holding period and turnover as the evaluation basis for inventory obsolescence losses.

4) Impairment of property, plant and equipment, right-of-use assets, investment properties and intangible assets

When an indication of impairment is assessed with objective evidence, the Company considers whether the recoverable amount of an asset is less than its carrying amount and recognizes the impairment loss based on difference between the recoverable amount and its carrying amount. The estimate of recoverable amount would impact on the timing and the amount of impairment loss recognition.

5) Useful lives of property, plant and equipment

As discussed in Note 3, "Summary of Material Accounting Policy Information - Property, Plant and Equipment", the Company reviews estimated useful lives of property, plant and equipment at the end of each year.

6) Recognition and measurement of defined benefit plans

Net defined benefit liabilities (assets) and the resulting pension expense under defined benefit pension plans are calculated using the Projected Unit Credit Method. Actuarial assumptions comprise the discount rate, employee turnover rate, average future salary increase and etc. Changes in economic circumstances and market conditions will affect these assumptions and may have a material impact on the amount of the expense and the liability.

7) Lessees' incremental borrowing rates

In determining a lessee's incremental borrowing rate used in discounting lease payments, a risk-free rate for relevant duration and the same currency is selected as a reference rate. The lessee's credit spread adjustments and lease specific adjustments are also taken into account.

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:

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

The Company invested 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.

The Company's share of profits and other comprehensive income (loss) of associates was recognized based on the audited financial statements.

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 30 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.

**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.

**28.** **RETIREMENT BENEFIT PLANS** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Defined contribution plans

The pension plan under the Labor Pension Act of ROC (the "LPA") is considered as a defined contribution plan. Based on the LPA, Chunghwa and its domestic subsidiaries make monthly contributions to employees' individual pension accounts at 6% of monthly salaries and wages. Its foreign subsidiaries would make monthly contributions based on the local pension requirements.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Defined benefit plans

Chunghwa completed its privatization plans on August 12, 2005. Chunghwa is required to pay all accrued pension obligations including service clearance payment, lump sum payment under civil service plan, additional separation payments, etc. upon the completion of the privatization in accordance with the Statute Governing Privatization of Stated-owned Enterprises. After paying all pension obligations for privatization, the plan assets of Chunghwa should be transferred to the Fund for Privatization of Government-owned Enterprises (the "Privatization Fund") under the Executive Yuan. On August 7, 2006, Chunghwa transferred the remaining balance of fund to the Privatization Fund. However, according to the instructions of MOTC, Chunghwa was requested to administer the distributions to employees for pension obligations including service clearance payment, lump sum payment under civil service plan, additional separation payments, etc. upon the completion of the privatization and recognized in other current monetary assets.

Chunghwa and its subsidiaries SENAO, CHIEF, CHSI, SHE, IISI and UTC with the pension mechanism under the Labor Standards Law in the ROC are considered as defined benefit plans. These pension plans provide benefits based on an employee's length of service and average six-month salary prior to retirement. Chunghwa and its subsidiaries contribute an amount no more than 15% of salaries paid each month to their respective pension funds (the Funds), which are administered by the Labor Pension Fund Supervisory Committee (the Committee) and deposited in the names of the Committees in the Bank of Taiwan. The plan assets are held in a commingled fund which is operated and managed by the government's designated authorities; as such, the Company does not have any right to intervene in the investments of the funds. According to the Article 56 of the Labor Standards Law in the ROC, entities are required to contribute the difference in one appropriation to their pension funds before the end of next March when the balance of the Funds is insufficient to pay the eligible employees who meet the retirement criteria in the following year.

The amounts included in the consolidated balance sheets arising from the Company's obligation in respect of its defined benefit plans were as follows:

(Concluded)

Relevant pension costs recognized in profit and loss for defined benefit plans were as follows:

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31** | **Year Ended December 31** |
|  | **2025** | **2024** |

------

The Company is exposed to following risks for the defined benefits plans under the Labor Standards Law in the ROC:

a. Investment risk

Under the Labor Standards Law in the ROC, the rate of return on assets shall not be lower than the average interest rate on a two-year time deposit published by the local banks and the government is responsible for any shortfall in the event that the rate of return is less than the required rate of return. The plan assets are held in a commingled fund mainly invested in foreign and domestic equity and debt securities and bank deposits which is operated and managed by the government's designated authorities; as such, the Company does not have any right to intervene in the investments of the funds.

b. Interest rate risk

The decline in government bond interest rate will increase the present value of the obligation on the defined benefit plan, while the return on plan assets will increase. The net effect on the present value of the obligation on defined benefit plan is partially offset by the return on plan assets.

c. Salary risk

The calculation of the present value of defined benefit obligations is referred to the plan participants' future salary. Hence, the increase in plan participants' salary will increase the present value of the defined benefit obligations.

The most recent actuarial valuation of plan assets and the present value of the defined benefit obligations were carried out by the independent actuary.

The principal assumptions used for the purpose of the actuarial valuations were as follows:

---

| | | |
|:---|:---|:---|
|  | **Measurement Date** | **Measurement Date** |
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  Discount rates | 1.50% | 1.75% |
|  Expected rates of salary increase | 1.00%~2.50% | 1.00%~2.25% |

---

If reasonably possible changes of the respective significant actuarial assumptions occur at the end of reporting periods, while holding all other assumptions constant, the present values of the defined benefit obligations would increase (decrease) as follows:

---

| | | |
|:---|:---|:---|
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  Discount rates |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.5% increase | $(722739) | $(790048) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.5% decrease | $889315 | $835848 |
|  Expected rates of salary increase |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.5% increase | $955672 | $903770 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.5% decrease | $(790904) | $(861833) |

---

------

The sensitivity analysis presented above may not be representative of the actual change in the present value of the defined benefit obligations as it is unlikely that the change in assumptions would occur in isolation of one another as some of the assumptions may be correlated. There is no change in the methods and assumptions used in preparing the sensitivity analysis from the previous period.

| | | |
|:---|:---|:---|
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  The expected contributions to the plan for the next year | $1096083 | $1223997 |
|  The average duration of the defined benefit obligations | 5.7~9 years | 6~10 years |

---

As of December 31, 2025, the Company's maturity analysis of the undiscounted benefit payments was as follows:

---

| | |
|:---|:---|
| **Year** | **Amount** |
| 2026 | $2423133 |
| 2027 | 3927532 |
| 2028 | 3483861 |

2) Global depositary receipts

The MOTC and some stockholders sold some common stocks of Chunghwa in an international offering of securities in the form of American Depositary Shares ("ADS") (one ADS represents 10 common stocks) in July 2003, August 2005, and September 2006. The ADSs were traded on the New York Stock Exchange since July 17, 2003. As of December 31, 2025, the outstanding ADSs were 186,374 thousand common stocks, which equaled 18,637 thousand units and represented 2.40% of Chunghwa's total outstanding common stocks.

The ADS holders generally have the same rights and obligations as other common stockholders, subject to the provision of relevant laws. The exercise of such rights and obligations shall comply with the related regulations and deposit agreement, which stipulate, among other things, that ADS holders are entitled to, through deposit agents:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a) Exercise their voting rights,

---

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.

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 appropriations of the 2024 and 2023 earnings of Chunghwa approved by the stockholders in their meetings on May 29, 2025 and May 31, 2024 were as follows:

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. Significant changes of contract assets and liabilities recognized resulting from product and service bundling were as follows:

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31** | **Year Ended December 31** |
|  | **2025** | **2024** |
|  Contract assets |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Net increase of customer contracts | $8350884 | $8616560 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Reclassified to trade receivables | (7841939) | (7442992) |
|  | $508945 | $1173568 |
|  Contract liabilities |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Net increase of customer contracts | $223586 | $197195 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Recognized as revenues | (215011) | (184110) |
|  | $8575 | $13085 |

---

------

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.

Revenue recognized for the year that was included in the contract liability at the beginning of the year was as follows:

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31** | **Year Ended December 31** |
|  | **2025** | **2024** |
|  Telecommunications business | $6888571 | $6721417 |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Incremental costs of obtaining contracts

| | | |
|:---|:---|:---|
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  Current |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Incremental costs of obtaining contracts | $338581 | $339172 |
|  Noncurrent |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Incremental costs of obtaining contracts | $1109029 | $1221652 |

---

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 years ended December 31, 2025 and 2024 were $944,587 thousand and $905,990 thousand, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. Remaining Performance Obligations

As of December 31, 2025, the aggregate amount of transaction price allocated to performance obligations for non-cancellable telecommunications service contracts that are unsatisfied is $45,354,477 thousand. The Company recognizes revenue when service is provided over contract terms. The Company expects to recognize such revenue of $26,157,614 thousand, $13,977,852 thousand and $5,219,011 thousand in 2026, 2027 and 2028, respectively. The variable consideration collected from customers on nonrecurring basis resulting from exceeded usage from monthly fee and revenue recognized for contracts that the Company has a right to consideration from customers in the amount corresponding directly with the value to the customers of the Company's performance completed to date have been excluded from the disclosure of remaining performance obligations.

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 year ended December 31, 2025. The compensation costs for stock options for the year ended December 31, 2024 were $2,688 thousand.

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.

**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.

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.

---

| | | |
|:---|:---|:---|
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  Discount for lack of marketability | 10.00%~30.00% | 20.00%~30.00% |
|  Noncontrolling interests discount | 10.00%~29.04% | 15.00%~29.04% |
|  Growth rate of long-term revenue | 1.33% | 0.12% |
|  Discount rate | 8.21%~11.60% | 8.32%~14.40% |

---

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.

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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 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:

---

<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.

| | | |
|:---|:---|:---|
|  | **Year Ended December 31** | **Year Ended December 31** |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; EUR | 7380 | 17070 |

---

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

b) This is mainly attributable to forward exchange contracts.

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:

---

| | | |
|:---|:---|:---|
|  | **December 31** | **December 31** |
|  | **2025** | **2024** |
|  Fair value interest rate risk |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Financial assets | $41450570 | $47562672 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Financial liabilities | 36418279 | 41444583 |

<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 $42,060 thousand and $27,912 thousand for the years ended December 31, 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.

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 $57,083 thousand and $340,268 thousand, respectively, as a result of the changes in fair value of financial assets at FVTPL and financial assets at FVOCI for the year ended December 31, 2025. If equity prices had been 5% higher/lower, pre-tax profit and pre-tax other comprehensive income would have increased/decreased by $48,424 thousand and $233,349 thousand, respectively, as a result of the changes in fair value of financial assets at FVTPL and financial assets at FVOCI for the year ended December 31, 2024.

&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.
