Walsin Lihwa continues to strengthen its product and market structure, increase the proportion of high-end applications and high value-added products, deepen synergies in new fields and new markets, while implementing sustainable development goals for the environment, society, and governance to ensure stable growth amid challenges and develop a key position in the industry chain. In 2024, Walsin Lihwa's Italian subsidiary, Cogne Acciai Speciali S.p.A., completed the acquisition of Com.Steel Inox S.p.A., which specializes in stainless steel and nickel-based alloy recycling and processing, as well as equity in Mannesmann Stainless Tubes GmbH (renamed DMV), a German stainless steel seamless pipe manufacturer, to secure key material sources in the stainless steel industry and deepen development of high-end product applications. The joint venture with Denmark-based NKT Group, Walsin Energy Cable System Co., Ltd., has begun construction of a submarine cable plant in Kaohsiung Port, actively entering the wind power energy industry chain. The Company pursues excellence in quality standards and green transformation goals to strengthen international competitive advantages. Accomplishments in 2024 Walsin Lihwa continues to deepen high-end product application areas and markets, actively integrating industry and internal resources to enhance international competitiveness. Upon reviewing the operational results for 2024, after four consecutive years of growth, consolidated revenue declined by approximately 5.5% due to weak global market demand. Profits from upstream raw materials and end products in the stainless steel sector were also affected, leading to a decline in gross profit and net income after taxes. The Company's consolidated revenue for 2024 was NT$179.3 billion, consolidated gross profit was NT$11.7 billion, and net income after taxes was NT$2.8 billion, with earnings per share of NT$0.69. Wire and Cable Business: The overall profitability of the Wire & Cable Business has grown compared to the previous year, primarily due to capturing domestic construction, industrial factory wiring demand, and resilient power grid opportunities, maintaining stable gross profit margins and profitability. Stainless Steel Business: The overall profitability of the Stainless Steel Business has declined compared to the previous year, due to unclear international trade tariffs and geopolitical risks, and weak global market demand causing end product prices to fall. Resources Business: The overall profitability of the Resources Business has declined compared to the previous year, due to global economic conditions affecting stainless steel raw material demand, thereby causing weak nickel prices, and delayed issuance of Indonesian mining quotas increasing costs, thereby affecting profitability. 5 Summary of 2025 Business Plan Wire and Cable Business: The Yangmei high-efficiency plant has entered full-capacity operation, with productivity improvement benefits and new business models for customer service, creating value and satisfaction for customers in the building wire market. We will develop ultra-high voltage cables, establishing four core engineering capabilities: production and manufacturing, integration of accessory equipment, cable jointing construction, and high-voltage power design to capture domestic resilient power grid opportunities. We will actively complete the construction of Taiwan's first submarine cable plant and initiate the pre-qualification procedure for submarine cable products. Stainless Steel Business: We will establish brand value with sustainable competitiveness and continue to increase the proportion of high- value products. We will also leverage the characteristics of steelmaking and rolling equipment to operate in differentiated product markets and provide high-value steel grades and certified market products. Through our Italian subsidiary Cogne's operations in Europe and its key position in the supply chain, we will implement global production and sales deployment and integrate synergies to become a leading enterprise in the global markets for stainless steel long products. Resources Business: Despite facing challenges from the global economic downturn and weak demand, resulting in weak nickel prices, thereby affecting profitability, we remain focused on maximizing production efficiency and optimizing operational costs. We will stabilize the production capacity of nickel pig iron and nickel matte, flexibly adjust the ratio between these products, and establish high-value nickel production processes. We will actively promote green manufacturing processes and low-carbon production to meet environmental trends and reduce production costs, continuing to demonstrate strategic significance in the stainless steel industry chain. Future corporate development strategy under the influence of external competition, regulations and overall business operation Looking ahead to 2025, U.S. tariff policies and protectionism continue to add uncertainty to the global economy. Against this backdrop, the Company's recent industrial development and regional deployment have strengthened its resilience in responding to perplexing situations. In the future, we will continue to promote core strategic initiatives, transform and upgrade our industrial structure, develop industrial ecosystem partnerships, implement digital and intelligent operational process management, launch circular economy initiatives and promote low-carbon transformation, cultivate our corporate brand, and deepen global market competitiveness. Through differentiated high-end applications and high value-added products, we will create sustainable value for Walsin Lihwa.

Diversity and Independence of the Board (1) Diversity of the Board In accordance with Article 20 of the Company's Corporate Governance Best Practice Principles and the "Principles of Election of Board Members and Managers and Guidelines for Continuing Education and Succession Planning" established by the Company, the Board of Directors will implement the objectives of diversity and independence in terms of expertise, experience and gender required for Board members, and will continue to invite appropriate candidates to join the Board of Directors in accordance with the above objectives in order to strengthen the balance of the Board of Directors in response to the Company's development strategies and changes in the internal and external environment. In order to achieve the desired objectives of corporate governance, the Board of Directors of the Company is composed of members from the management team, managers of relevant industries and professionals with financial, business and accounting backgrounds, who effectively perform the duties of Board members with different fields and work backgrounds. These duties include establishing and maintaining the Company's vision and values, assisting in promoting corporate governance and strengthening management, overseeing and evaluating the implementation of management policies and operational plans, and being responsible for the Company's overall economic, social, and environmental operations to enhance corporate governance and corporate value from the perspective of stakeholders. The Company has built its strength by being focused on the wire and cable, stainless steel, resources, and commercial real estate fields and become a model of business excellence moving towards the manufacturing service industry. There are eleven directors on the Company's Board of Directors of 20th term: Yu-Lon Chiao, Chairman, has been working in the business field of the Company for a long time and has a good understanding of the operation and development of the industry, with an open-minded leadership style that encourages adoption of suggestions; Shyi- Chin Wang, Vice Chairman, previously serving as President and Acting Chairman of China Steel Corporation, has dedicated many years to the stainless steel industry and possesses substantial operational management experience and expertise in advancing and transforming Taiwan's domestic stainless steel industry; Directors Yu-Cheng Chiao, Yu-Heng Chiao, and Yu-Chi Chiao have joined the management team of the Company and therefore are familiar with the organization and business operation of the Company and are good at operation management and investment judgment; Andrew Hsia, Director, comes from a diplomatic background with an international perspective and therefore has a good grasp of the conditions of the Southeast Asian market and can fully assist the Company in making relevant investment decisions; and the female Director, Director Wen-Chien Hsieh, as the Managing Partner of a law firm, possesses extensive practical legal experience and expertise in business management.

(2) Independence of the Board: The Company should have 3 Independent Directors in accordance with the law, but it has 4 Independent Directors among its 11 Directors. Four Directors have spousal or second-degree kinship relationships with other Directors, representing 36% of the total board members. This complies with Paragraph 3, Article 26-3 of the Securities and Exchange Act, which stipulates that more than half of the director seats shall not be held by persons having spousal or second-degree kinship relationships. In order to improve the Company's operation and development and Corporate Governance Report 18 operation of corporate governance practices, none of Independent Directors are subject to Paragraphs 3 and 4 of Article 26-3 of the Securities and Exchange Act. (3) Diversity Management Objectives The Company implements a board diversity policy with specific management objectives that include: Independent Directors representing more than one-third of the board; a majority of Independent Directors not serving more than three consecutive terms; and female Directors occupying at least one-third of all board seats. Independent Directors currently represent 36% of the board, with a majority serving fewer than three consecutive terms. The board currently consists of 10 male directors (91%) and 1 female director (9%). Since the election of the Board of Directors of the 20th term was completed in 2023, the Company will prioritize seeking female director candidates in the future to achieve the goal of having female directors occupy at least one-third of all board seats. 19 Implementation of Board Diversity: Title Name Nationality Gender Age Term of Independent Director Industry Experience Professional Capabilities Energy & Environmental Protection Merger, Acquisition& Investment Finance & Legal Information Technology Stainless Steel Business Management Leadership & Decision-making Market Marketing International Trade Risk Management ESG Finance, Accounting & Legal Professional Certification Chairman Yu-Lon Chiao R.O.C.

Description of the policy, standards and packages of remunerations, procedure for making such decision and relation to business performance: (1) The Company's policy for remunerating its directors is formulated based on the Company Act and the Company's Articles of Incorporation. The remuneration of directors for the current year shall be limited to an amount not exceeding 1% of the current year's earnings and shall be paid in accordance with the Rules Governing the Compensation of Directors and Functional Members of the Company. The Company's operating strategy, profitability, future development and industry condition, as well as each director’s participation in and contribution to the Company’s operation (such as serving on functional committees or being invited to important business meetings), have also been taken into account in order to give them reasonable remuneration. The Compensation Committee then submits a proposal, which is passed at a board meeting before the policy takes effect. (2) In order to ensure that the performance of managers is closely linked to the Company's strategy and that their overall compensation is competitive in the market, the Company has established the Regulations for the Evaluation of Managerial Performance and Compensation as the basis for performance evaluation and compensation of managers. The aforementioned regulations include policies, systems, standards and structures for performance evaluation and compensation of managers, which shall be reviewed by the Compensation Committee and submitted to the Board of Directors for approval. Manager's remuneration includes salary and bonus: their salary is based on the Company's business strategy and profitability by taking into account the manager's professional ability, scope of responsibility and market competitiveness; for the bonus, the Company will take into account the results of individual performance evaluation, the reasonableness of the link between its operating performance and future risks. The Compensation Committee then submits a proposal, which is passed at a board meeting before the policy takes effect. However, if there is a significant risk event that affects the Company's reputation, internal mismanagement, personnel malpractice and other risk events attributable to any manager, the bonus payable to him/her will be reduced or cancelled. The manager's performance evaluation structure consists of "results evaluation" and "function evaluation". After setting targets at the beginning of the year, the management performance review is conducted quarterly and the performance evaluation is conducted semi-annually. The key focus areas for performance evaluation include the execution results of strategic plans, business planning capabilities, profitability, decision-making abilities, leadership and management skills, and the ability to develop leaders. To fulfill the responsibility of sustainable development, a new "Corporate Sustainability Development Indicator" has been added in 2024, accounting for 10% of the evaluation. This indicator aims to achieve the Company's strategic objectives in the environmental, social, and governance (ESG) dimensions and to link corporate sustainable development with the compensation policy for senior management.

Evaluation of achievement of enhancing the Board’s performance (e.g. establishing an Audit Committee and increasing information transparency): (1) Formulation of regulations related to the corporate governance: In addition to explicitly stating the powers and duties of the Board of Directors in the company's articles of incorporation, the Company also follows rules and regulations including the "Board of Directors Procedural Regulations", "Guidelines for the Ethical Conduct of Directors and Managerial Officers", "Procedures for the Processing of Critical Internal Information", "Corporate Governance Principles and Practice", "Corporate Management Integrity Principles", "Behavioral Guidelines and Operation Procedures for Honest Practices", "Guidelines for the Ethical Conduct of Employees", "Rules for Suggestions and Complaints from Related Parties", and "Practical Guidelines for Corporate Social Responsibility" in order to strengthen operations of the Board of Directors as well as corporate governance. (2) Evaluation of the Performance of the Board of Directors and Functional Committees: To implement corporate governance and enhance the Company's board functions, and to set forth performance objectives to improve the operation efficiency of the board of directors, the Regulations Governing Board Performance Evaluation were established pursuant to the Corporate Governance Best-Practice Principles for TWSE/TPEx Listed Companies and shall apply to the Board of Directors, functional committee and individual directors. According to the Company's Regulations Governing Board Performance Evaluation, the Board of Directors must conduct a performance evaluation at least once a year. The Board's performance evaluation should be conducted by an external professional independent institution or a team of external experts and scholars at 39 least once every three years, and should be performed at the end of each year for that year's performance evaluation. The internal self-assessment method for the Board and each functional committee involves each agenda working group providing questionnaires for Board members to complete in December each year. The questionnaire results are compiled and presented to the Nomination Committee and the Board of Directors for performance evaluation reporting. The external and internal performance evaluations of the Board of Directors, Compensation Committee, Audit Committee, Sustainable Development Committee, and Nomination Committee for 2024 were completed in December 2024 and reported to the Board of Directors on January 6, 2025. A. Regarding external evaluations: In 2018, the Company first appointed Taiwan Corporate Governance Association ("TCGA"), an independent third party with which the Company has no business dealings, to evaluate the effectiveness of its Board of Directors once every three years. The evaluation was conducted by means of questionnaires and on-site interviews on five major aspects of the board of directors, i.e., board composition and division of responsibilities, board guidance and supervision, board authorization and risk management, board communication and collaboration, and board self-discipline and advancement. Through the review by a professional organization and with the guidance of and communications with the evaluation members, the Company obtained professional and objective evaluation results and recommendations. The external evaluation of the Board's performance for 2024 was completed in December 2024 and reported to the Board of Directors on January 6, 2025. The measures in response to the recommendations of the external evaluation institution in 2024 are as follows: Recommendations of External Evaluation Institution Measures Setting Goals for the Board of Directors and Functional Committees It is recommended that after the election of each term of the Board of Directors, goals should be established for the current term of the Board and its functional committees. Additionally, the responsibilities of each functional committee should be reviewed, and the relevant objectives should be incorporated into the Performance Evaluation Indicators for the Board of Directors and Functional Committees to ensure that the goals of the Board and functional committees for their term can be reasonably achieved. Following this recommendation, self-assessment items regarding assignments or objectives for Board members for their term have been added, with the Nomination Committee conducting regular reviews and providing recommendations. Each functional committee has similarly implemented these additional items accordingly. B. Regarding the annual internal evaluation for 2024, the 2024 Board of Directors' and functional committees' performance self-evaluation results go as follows: (a) Board of Directors' overall average score 4.80 points (out of 5 points) (b) Board members' overall average score 4.77 points (out of 5 points) (c) Compensation Committee: 5.0 points (out of 5 points) (d) Audit Committee: 5.0 points (out of 5 points) (e) Sustainable Development Committee: 4.97 points (out of 5 points) (f) Nomination Committee: 5.0 points (out of 5 points) In December 2024, the Company conducted an internal annual board performance evaluation of the board of directors, individual board members and functional committees (i.e., the Compensation Committee, Audit Committee, Sustainable Development Committee, and Nomination Committee) in accordance with the evaluation indicators and evaluation procedures specified in these Rules, and compiled and scored the data after the questionnaires were collected, and made recommendations for improvement. This year, the Company has made recommendations for improvement in the level of Directors' participation in the Company's internal control and operations, as well as the follow-ups on the recommendations made by an external evaluation institution in 2024, both of which were consolidated and reported to the Nomination Committee on January 6, 2025 and the Board of Directors' meeting, the details of which were disclosed on the Company's website. (3) Implementing the performance evaluation of the functional committees: In accordance with the "Regulations for the Evaluation of the Performance of the Board of Directors (including Functional Committees) and their Remunerations" formulated by the Compensation Committee based on the latest version published by the Competent Authority, our Compensation Committee, Audit Committee, Sustainable Corporate Governance Report 40 Development Committee, and Nomination Committee members in December every year evaluate themselves by the assessment indicators to measure the corporate leadership strategic directions and oversee the corporate operational performance in an effort to improve shareholders' long-term value. (4) Actively participating in corporate governance: In recent years, the Company has actively participated in the promotion of the corporate governance and the transparency in information disclosure. Walsin Lihwa was listed as the top 5% outstanding companies by seven consecutive times of Corporate Governance Evaluation from 2017 to 2023. The Company also received five outstanding recognitions: Taiwan's Top 100 Sustainability Model Business Award, Information Security Leadership Award, Platinum Sustainability Report Award (Traditional Manufacturing Industry), Bronze Prize for English Sustainability Report, and Sustainable Micro Movie Bronze Award. The Company will continue making efforts to maintain among the top with respect to the Corporate Governance Evaluation Results. The Company not only will continue to strive to actively participate in the corporate governance evaluation, but also has formed a project to improve corporate governance matters and enhance corporate governance capabilities. The Company is committed to enhancing the transparency of information. In addition to announcing financial information in accordance with laws and regulations, the Company also holds regular investor conferences four times a year. In 2024, the Company was granted a long-term credit rating of 'twA-' and a short-term credit rating of 'twA-2' with a 'negative' outlook by Taiwan Ratings. In addition, it was our first time in 2023 to volunteer to fill in the DJSI and scored 57 points (ranked 7/188 in ELQ Electrical Components & Equipment for the same industry). The Company's financial structure was certified by an external organization, and the disclosure of information to stakeholders was also enhanced through the external release of credit ratings. (5) Enhancing the board’s functions and decision-making quality: In order to bring into play the functions and decision-making quality of the Board of Directors, our company regularly holds strategic meetings on a quarterly basis to enable the directors to understand our financial and business conditions and the formulation of major business strategies and the implementation of related plans. In addition, quarterly operational meetings are also held to help directors understand the operational content through reporting by operating units, so as to improve the performance of the Board of Directors. In the meantime, the directors may provide their effective guidance out of their expertise and experience to the operating units during such meetings. (6) Heavy reliance on the independent directors’ functions: Authorizing independent directors to utilize their own expertise and regularly participate in our company's investment assessment projects and matters relevant to corporate governance. The Audit Committee was formally established by all independent directors after the shareholders' meeting on May 26, 2017, and the Audit Committee of the third term was formed by all independent directors on May 19, 2023; the Compensation Committee of the fifth term was established on May 19, 2023, with all independent directors acting as its members.

The current status and development of the industry (1) Wire and Cable Business According to the statistical forecast report by the International Copper Study Group (ICSG), refined copper production in 2024 is expected to increase by 3.7% year-over-year, with primary production (electrolysis and electrodeposition from ore) increasing by 3.9% and secondary production (from scrap) growing by 3%. The estimated annual output will reach 27.39 million metric tons. The consumption of refined copper in 2024, primarily benefiting from growth in the Mainland China market (3%), is expected to increase by 2.6% year-over-year, with an estimated annual consumption of 27.21 million metric tons, resulting in a supply- demand gap of 180,000 metric tons. Mainland China continues to expand its copper smelting capacity, with refined copper production continuing to grow. Official estimates predict approximately 4.5% growth in refined copper production in 2024. According to the statistical analysis report published by the International Wrought Copper Council (IWCC), Mainland China is the world's largest copper consumer, with copper rod sales reaching 10.05 million metric tons in 2024, an annual increase of 3.0%. Taiwan's annual copper rod sales, after showing a downward trend for two consecutive years, have now shifted to growth. Sales in the first half of 2024 increased by 12.6% year-over-year, with annual sales estimated at approximately 360,000 metric tons. The cable market is dominated by procurement from enterprises in the electric power sector, primarily used for transmitting power from power plants to offices or residences. In recent years, the cable industry has benefited from continued investment in new infrastructure, accelerated energy transition, and steady progress in ultra-high voltage construction. According to public data from the Statistics Department of the Ministry of Economic Affairs, Taiwan's domestic sales volume of power cables in 2024 increased by approximately 6.2% year-over-year, showing a continuous growth trend over the past six years. This growth has been supported by Taiwanese businesses returning to Taiwan to invest in plant construction, as well as the recent rise of artificial intelligence and high-performance computing. To meet industrial electricity demand and ensure stable power supply, Taiwan Power Company has continued to promote its resilient power grid plan in addition to its existing long-term power transmission and transformation plan, further stimulating growth in demand for wires and cables. (2) Stainless Steel Business According to market research firm SMR, global crude stainless steel production in 2024 is estimated to be 67.77 million metric tons, a 5.3% increase from 2023. The largest production region is Mainland China, with crude stainless steel production reaching 41.60 million metric tons, a 4.9% increase from 2023. Indonesia and India are also major growth drivers, with Indonesia's production of 5.40 million metric tons representing a 12.0% growth from 2023, and India's production of 5.30 million metric tons showing a 10.4% growth from 2023. In terms of stainless steel product structure, flat products accounted for 85% of total production in 2024, with hot-rolled products accounting for 19% and cold-rolled for 81%. Long products accounted for 15% of total production, with hot-rolled bars representing 41% of long products, wire rods 33%, and billets 25%. About 46% of end-use applications for stainless steel are in consumer durable goods, 26% in industrial production (such as machined parts), 18% in structural components, and 10% in transportation. The top five global long product stainless steel companies by production volume are Tsingshan, Jiangsu Delong, Walsin Lihwa, Viraj, and Swiss Steel (according to SMR's 2024 statistical report). The steel industry faces overcapacity and severe price competition. Some steel mills have chosen to exit, while others have improved operational efficiency through consolidation, restructuring, and eliminating outdated capacity. In recent years, several stainless steel groups have formed internationally (e.g., Tsingshan, Baosteel/Wuhan Iron and Steel/Taiyuan Iron, and Outokumpu), with each group developing Business Overview 124 distinct business models. Larger players, such as those in China and Indonesia, who focus on general materials sales, choose to control upstream raw materials to reduce costs; smaller players, on the other hand, opt for the development of high-profit products and application industry. (3) Resources Business Global nickel pig iron production capacity is mainly concentrated in Mainland China and Indonesia. Since 2020, following Indonesia's ban on ore exports, the nickel pig iron industry chain has accelerated its shift from Mainland China to Indonesia, making Indonesia the world's largest nickel pig iron producer. In 2024, the total high nickel pig iron production capacity in Mainland China and Indonesia reached 2.77 million metric tons of nickel, with total production reaching 1.74 million metric tons of nickel. This represents a 2% increase in capacity and a 3% increase in production compared to 2023. Mainland China's total high nickel pig iron production was 260,000 metric tons of nickel, a 15% decrease from 2023, primarily due to uneconomical production that has led to continued decline in overall competitiveness. Indonesia's total high nickel pig iron production was 1.47 million metric tons of nickel, a 7% increase from 2023, with the growth rate slowing due to Indonesian nickel ore policies, declining ore grades, and weather impacts. In 2025, Mainland China's nickel pig iron production is expected to continue shrinking due to uneconomical production, while Indonesia's ore supply is expected to be slightly more abundant than in 2024. Although Indonesia's nickel pig iron production is expected to increase due to plans for a small number of new production lines, attention must still be paid to changes in Indonesia's nickel ore-related policies. Furthermore, in response to the green energy transformation and flourishing development of the downstream new energy industry chain, large amounts of capital have flowed into Indonesia since 2020. Production capacity for battery-grade nickel intermediate products, such as nickel matte and mixed nickel- cobalt hydroxide precipitate (MHP), began to be released from 2021 and has grown rapidly from 2022 to 2024. In 2024, Indonesia's MHP production reached 310,000 metric tons of nickel, a 97% increase from 2023, while high-grade nickel matte production reached 270,000 metric tons of nickel, a 12% increase from 2023. Indonesia still has plans for substantial nickel intermediate product capacity in the coming years. New capacity is expected to continue coming online in 2025, with the overall industry chain gradually extending downstream, although overall nickel intermediate product output will be affected by the Indonesian government's nickel ore production control policies. In 2024, the global electric vehicle market growth momentum slowed due to the high interest rate environment and elevated global geopolitical risks. In 2025, demand may continue to slow due to high policy uncertainty across countries and ongoing geopolitical instability. After President Trump's inauguration, the United States may tighten subsidy policies for electric vehicles and strengthen controls on Foreign Entities of Concern (FEOC), prompting upstream battery industry chains for electric vehicles sold in the U.S. to actively seek raw materials produced by non-FEOC companies. (4) Commercial Real Estate Business In 2024, Nanjing's office building stock exceeded 5 million square meters, with market demand continuing to recover. The annual net absorption reached 207,000 square meters, a year-over-year increase of 28.6%. In terms of transaction types, in addition to traditional leasing customers, diverse transactions including those from operators and office conversions to commercial purposes also contributed to the annual transaction volume. Industries showing strong growth included telecommunications, media, and technology sectors—primarily focused on chips, big data, and software services—while the financial industry, centered on insurance, banking, and funds, demonstrated strong overall leasing capacity. Active transaction areas were concentrated in the Xinjiekou and Hexi districts. In 2024, Nanjing's retail market total inventory increased to approximately 7.27 million square meters. In the first three quarters, the city achieved total retail sales of consumer goods amounting to RMB 637.775 billion, a year-over-year increase of 3.3%. Driven by economic work conferences, consumer confidence was boosted and demand expanded, promoting the development of retailers in industries such as catering, 125 smart home appliances, 3C products, automobiles, sports, and entertainment in Nanjing. Brand merchants across business models continued to expand, with several brands entering the Nanjing market for the first time. 2.

Product development trends and competition (1) Wire and Cable Business Development trend: In addition to the traditional construction and infrastructure cables, there are many green energy related cable applications and products that have emerged in response to the global developing trend of net zero transition. For example, in the field of energy creation and transmission, solar power cables that need to prevent UV degradation, wind turbine cables that can withstand harsh environments, and submarine cables that transmit power from offshore wind turbines back to land or transfer power across borders between countries, are all products that are actively developed by major cable manufacturers around the world. In addition, in the area of energy storage and use, the electrification of transport equipment and smart power allocation, cable sets for power replenishment systems, and cables for energy storage equipment are all new products that the wire and cable industry is competing for development. Competition: From the historical output of Taiwan's power cable market, there is still an oversupply of capacity in the overall cable market and competition is relatively fierce. However, with the expansion of emerging technology applications, increasing industrial electricity demand, the government's acceleration of various energy policies, and the expedited implementation timeline of Taiwan Power Company's resilient power grid plan, new momentum has been added to the industry. (2) Stainless Steel Business Development trend: In terms of product development, apart from actively developing nickel-free steel grades, major stainless steel makers are also developing functional stainless steel for specific applications. For example, in response to the demand for automation, the demand for wear-resistant, high-precision and zero-defect materials has increased. In the past, key technologies were held in Japan, Europe and other countries, but Asian steel makers have also continued to invest in research and development in recent years, and to refine their own technological capabilities. With the rising awareness of environmental protection, stainless steel is more widely used in various fields, and there are many cases of replacing carbon steel with stainless steel in the construction, transportation and other industries. In the renewable energy industry, stainless steel components can also be found in solar panels, wind turbines and renewable energy vehicles. 127 Competition: Indonesian steel mills will dominate the Asian market with the advantage of low-cost raw materials. With the promotion of capability control policy in Mainland China, the steel industry has shifted from volume to value-added, and large-scale steel makers have started to consolidate with the strategy of eliminating the weak and leaving the strong. The rest of the steel makers in Europe, America, Japan, and Korea have focused on niche industrial applications with high certification thresholds to add value to their products through end-use differentiation, specializing in the development of specialty steel applications. In addition, in response to the trend towards net-zero carbon emissions, major European steel makers have begun to focus on providing products with low carbon emissions or more sustainable significance. (3) Resources Business Development trend: Stainless steel plants in Mainland China and Indonesia are expanding their production capacity, and the demand for nickel pig iron and scrap steel will continue to rise, while nickel pig iron in Indonesia has a cost advantage and is economical for downstream steel plants. In the following years, there will still be a few new production lines to be built. In addition, in response to the continuous growth of the new energy industry chain, some of the RKEF (Rotary Kiln Electric Furnace) production lines have started to change their processes in 2022 to make their output more flexible to switch between nickel pig iron and nickel matte; therefore, the "nickel matte - nickel sulfate - pure nickel" process has emerged. Price differentials between different nickel products will make their sales portfolios be more diversified, and the overall nickel market will reach a dynamic balance between supply and demand. Competition: Indonesia's RKEF production lines have significantly increased since 2021, but after three years of rapid growth, this expansion has slowed. By 2024, Indonesia had nearly 300 RKEF production lines. Subsequently, due to the Indonesian government's regulation of nickel ore supply and restrictions on pyrometallurgical projects, existing production lines are expected to experience reduced capacity growth rates, gradual reductions, and product transformations. Additionally, production lines with higher costs and poor operations may gradually be phased out. Some RKEF production lines began modifying their processes in 2022 to create more flexible output capabilities, allowing them to switch flexibly between nickel pig iron and nickel matte production. However, the overall production capacity now exceeds the demand from both the stainless steel smelting and new energy industry chains. (4) Commercial Real Estate Business Development trend: Nanjing is an important center city in China's eastern region and an international comprehensive transportation hub. In 2024, its regional GDP reached RMB 1.8 trillion, with a total output growth of 4.5%, steadily ranking among the top ten in the country. With its continuous population inflow and strong economic foundation, Nanjing is one of China's core cities for real estate development. The supply of new Grade A office buildings in Nanjing remains abundant, which is favorable for tenant upgrades and expansions. Since the beginning of the year, the financial industry, represented by the insurance sector, has been actively seeking changes. The relocation and upgrade demands of large enterprises continue to expand, with high-standard Grade A office buildings in core urban business districts remaining the most resilient development areas. With the support of various policies, Nanjing's retail market will continue to strengthen its development of first-launch economies, cultivate new consumption modes, create diversified consumption scenarios, upgrade commercial districts, renovate existing commercial properties, and apply digital technologies. Nanjing's retail market will maintain its active momentum and further develop and upgrade. Competition: Competition for Grade A office buildings has intensified in certain areas, with an increasing number of property owners beginning to offer customized renovation leasing solutions, more flexible business terms, more comprehensive business supporting facilities, and more comprehensive soft services. In the retail market, adjustments and renovations of existing projects have become more active, leading to increased differentiation between projects, with mid-to-high- end shopping centers maintaining stronger competitiveness.

Overview of supply and demand and projected growth (1) Wire and Cable Business According to the global copper production forecast by the International Copper Study Group (ICSG), global copper supply will grow by about 3.5% in 20245 In terms of refined copper production, ICSG expects refined copper production to grow by 1.6% in 2025. In terms of the refined copper consumption, despite a challenging global economic outlook, the anticipated improvement in manufacturing activities, ongoing energy transition, and the development of new semiconductor capacities globally are expected to support the growth in refined copper consumption, with a projected increase of 2.7% in 2025. Development of power grid infrastructure in major countries and the global trend towards clean energy and electric vehicle development are expected to continue to support the long-term growth of copper demand. Mainland China continues to promote infrastructure construction, with power supply and grid engineering investment growth remaining promising. The State Grid of China has announced that in 2025, it will focus on optimizing the main power grid, reinforcing the distribution network, and supporting high-quality development of new energy sources. It will continue to implement major projects, commence construction on a new batch of key engineering projects, actively expand effective investments, and drive upstream and downstream industry chains. It is estimated that in 2025, State Grid's investment will exceed RMB 650 billion for the first time. Additionally, with the continued expansion of the automotive industry, the penetration rate of new energy vehicles has climbed to new highs, with both production and sales of new energy vehicles showing double-digit growth year-on-year, consistently ranking first globally in both production and sales. This growth trend is expected to continue in 2025. In summary, from the perspective of copper end-product demand, the development of the aforementioned industries should drive copper consumption demand and provide a stable foundation for the production and sales of cable-related products. In 2024, the Bureau of Energy of the Ministry of Economic Affairs published Taiwan's latest national power resource supply and demand report, and planned the long-term power demand and construction blueprint for the next decade. It is estimated that Taiwan's total electricity consumption will grow by 12% to 13% by 2030, in response to the estimated value of Taiwan's economic growth rate, as well as the expansion of the semiconductor industry driven by AI technology and electric vehicle promotion policies. By 2033, the annual average growth rate of Taiwan's national electricity demand is predicted to be 2.8%. The Ministry of Economic Affairs emphasized future construction priorities, including new power generation unit development plans, renewal of power grid substations, and the establishment of energy storage systems to accommodate the high penetration rate of renewable energy, thereby ensuring stable power supply. Taiwan Power Company continues to develop power sources and invest in the power grid to meet the electricity demands arising from economic development and government policies. Fitch expects that Taiwan Power Company's capital expenditure will reach between NT$222 billion and NT$276 billion annually from 2024 to 2027, a significant increase compared to the average capital expenditure of the past four years (NT$160 billion). The surge in Taiwan Power Company's capital expenditure mainly comes from the construction of natural gas and offshore wind power plants, as well as strengthening power grid resilience, which will boost orders and revenue for related businesses, with the wire and cable industry being one of the largest beneficiaries. With demand generated simultaneously by various government plans, future order visibility for cables is promising. 135 (2) Stainless Steel Business The expansion of global stainless steel and crude steel production capacity has reached a plateau. Under the carbon emission control policy in mainland China, factories are replacing old instead of creating new capacity, while European and American steel mills, after years of consolidation, have ceased increasing capacity and shifted their focus to high-end industry applications and nickel-based alloy production. In Indonesia, the pace of capacity investments has slowed down, while stainless steel makers in the rest of the countries around the world will operate only through the development of steelmaking technology, so that the existing capacity may be slightly increased; therefore, we will not see the previous annual growth of capacity in double-digits any longer. On the demand side, the International Stainless Steel Forum (Worldstainless) estimates that global stainless steel consumption will grow by 3.0% in 2025, maintaining a positive growth rate. However, considering the impact of the current global economic uncertainty, such growth may be very limited. Although the increase or decrease in stainless steel consumption is susceptible to fluctuations due to changes in the current year's economy, the compound annual growth rate of stainless steel consumption during the past 10 years is about 2% to 3%, and we expect this trend to be maintained in the coming years. The growth of demand also varies depending on the product type. Flat panel products account for more than 80% of the total stainless steel usage and are widely used in various end-use applications, with a high correlation between the increase or decrease in demand and the economic conditions. The application of long strip products are industry-specific; it is expected that the robust development of infrastructure, machinery and equipment, transportation, new energy, and semiconductor in recent years will drive the demand for long strip products, which will increase at a rate faster than the flat panel products in the next few years. (3) Resources Business In 2024, as the growth in global nickel pig iron market supply slowed, the demand side exhibited structural changes. Although Indonesia's nickel pig iron production continues to increase, the growth rate has slowed to approximately 7%, lower than the 19% growth rate in 2023, primarily affected by pressure on nickel ore supply and some production lines shifting towards nickel matte. China's nickel pig iron production continues to decline due to increased production costs and import subsidy-related policies. Despite limited new nickel pig iron capacity in Indonesia and government policy restrictions on RKEF capacity deployment, the supply of Indonesian nickel products exceeds demand. However, nickel pig iron still holds advantages in terms of cost and nickel content, maintaining economic viability for stainless steel production and resilient demand. Meanwhile, fluctuations in scrap steel prices and nickel metal price trends are core factors affecting the economic viability of nickel pig iron. Overall, the cost advantage of nickel pig iron compared to scrap steel will continue to support its dominant position as a raw material for stainless steel smelting, although the market may face more uncertainties due to oversupply of raw materials. In response to the green energy transition and the flourishing development of the downstream new energy industry chain, the production capacity of intermediate nickel products for batteries, including nickel matte, began to be released in 2021 and rapidly increased from 2022 to 2024. In 2024, Indonesia's high nickel matte production reached 270,000 metric tons of nickel, an increase of 12% compared to 2023. Indonesia plans to continue expanding intermediate nickel product capacity in the coming years, with new capacity expected to be commissioned in 2025, and the overall industry chains gradually extending downstream. However, the overall output of intermediate nickel products will be affected by the Indonesian government's policies on nickel ore production control. In terms of our agency services, in 2022, the supply chain anomalies normalized, and the total quantity of 300 series hot rolled stainless steel imported into Taiwan was about 900,000 to 950,000 metric tons in 2023, which is almost the same as the import quantity in 2022. This level of import volume is equivalent to the rigid demand for the Taiwan market. In 2024, due to final judgments on anti-dumping and Business Overview 136 anti-subsidy cases from the EU favorable to Taiwanese businesses, which stimulated material preparation demand, the annual order volume exceeded 1 million metric tons. It is estimated that in 2025, Taiwan's imports of stainless steel from Indonesia will return to normal levels. (4) Real Estate Business Nanjing Jiangyou District is building a Yuantong shopping district centered on the Yuantong subway station to create a "demonstration area of international consumer center city."

Following the installation or modification of the stationary pollution source mentioned in the preceding paragraph, the entity shall submit documentation demonstrating compliance with relevant provisions of these Regulations to apply for and obtain an operating permit from the competent authority of the municipality or county (city), or from an agency commissioned by the central competent authority, and shall operate in accordance with the conditions specified in the issued permit. Penalty Amount NT$160,000 Note: The standard for disclosure of major fines is NT$100,000/RMB22,000 Although our Taiwan plants did not incur any major environmental penalties (defined by the Financial Supervisory Commission as those exceeding NT$1 million) in 2024, there were three environmental compliance issues, all of which were promptly remediated with enhanced personnel and procedural management. Despite being subject to intensified scrutiny by central and competent authorities as part of the steel and surface treatment industries, the Company experienced no pollution leakages Business Overview 146 resulting in production stoppages or community protests, and no wastewater or waste material leakage incidents occurred at any of our plants. Moving forward, we will continue self-monitoring according to our environmental management system framework. Additionally, the Environmental Safety Management Committee will conduct periodic inspections to verify environmental regulatory compliance at all plants and strengthen on-site surveillance to ensure regulatory conformity and prevent pollution incidents. (2) Future response measures (including improvement measures) and possible expenses: Despite the large amount of manpower, materials and funding invested in environmental protection to comply with international benchmarks over the years, Walsin Holdings was still fined for pollution. To keep pollution under adequate control, the Company requires factories in Taiwan and overseas to step up self-regulation to avoid human errors and to implement economically feasible environmental management projects. Internal audit and environmental education & training (including regulatory identification) will also be applied to assist in reinforcing self-regulation and horizontal development at various factories. Environmental investment plans and management measures are as follows: 1. Obtained ISO-14001 certification for system management: In line with international environmental conventions, factories in both Taiwan (Hsinchuang plant 1, Hsinchuang plant 2, Yangmei plant, Taichung plant and Yenshui plant) and mainland China (Shanghai Walsin Lihwa Power Wire & Cable plant, Nanjing plant, Jiangyin plant, Yantai plant and Changshu plant) have all obtained "Environmental Management System" certification. In order to ensure the operational effectiveness of Walsin's environmental management system, the Company hired a professional consulting team in 2017 to instruct 10 domestic and overseas factories to transition to ISO 14001:2015. Basic operation for ISO 45001 was also introduced as a pilot program, as environmental protection and vocational safety & health management system are integrated into a universal operating model across the entire group while on-site guidance is also provided. Consistency in documentation and stability in system operation are required of these factories. Through educational training at various factories, the spirit of the management system is deeply ingrained in actual factory operation after multiple training sessions focusing on topics ranging from regulatory interpretation to actual operation. Furthermore, with a proactive attitude, we will continue to improve our overall environmental protection efforts and vocational safety & health condition. We will strive to enhance environmental performance, reduce environmental loss, improve corporate image and boost our international competitiveness. Walsin has completed the integration and version conversion of its management system at all of its factories at home and abroad in 2018, with the certificates being valid for three years. The relevant certificate documents are placed in the document management section of Walsin Lihwa website and are updated regularly. 2. Air pollution management: Comply with the air pollution control laws in Taiwan and in China and apply for permits for fixed (atmospheric) pollution source ranges that are progressively announced. The various plants in Taiwan and in China have obtained operating (emission of pollutants) permits for various manufacturing processes and facilities, reducing atmospheric emissions. 3. Greenhouse gas emission and campaign for reduction: To counter climate change and global warming, reduction in greenhouse gas emission is a necessary measure. GHGs inventories provide compliance basis for efforts to reduce greenhouse gas emission. Since 2015, the Company has established the "Safe Environment Information Platform--the ability to conduct GHGs inventories and to calculate carbon emission for products" to collect greenhouse gas emissions at home and abroad. Through continuous review every year and smart system management, the Company keeps optimizing its greenhouse gas emissions. Through the electronic system, we can grasp the current year's quarterly emissions and compare them with the same period last year, and further produce the trend graph for the quarterly meeting of the Environmental, Safety and Health Management Committee to review the carbon emissions regularly, so as to effectively review and manage the Company's carbon emissions. In addition, in order to improve the company-wise operation of the greenhouse gas control system, we also plan to promote the implementation of ISO 14064-1 in each plant. In 2015, our Taichung and Yenshui plants in Taiwan have obtained ISO 14064-1 certification, and the latest certificates and expiration dates are regularly posted on our CSR website every August. Hsinchuang, Yangmei, Taichung, and Yenshui Plants have also obtained the new 147 version of ISO 14064:2018 certification in 2021, and at the same time, we planned to promote the introduction of ISO 14064-1 in overseas plants and have executed the same and obtained a third-party certification from 2023 to 2024. Furthermore, Walsin continues to monitor developments in carbon emissions trading, the EU Carbon Border Adjustment Mechanism, Taiwan's carbon fee system, and is formulating internal carbon pricing strategies. The Company participates in mainland China's carbon trading market operations to secure future carbon allowances and ensure sustainable business development. Safety and Environmental Information Platform Since 2015, “Safety and Environmental Information Platform - Greenhouse Gas Inventory and Calculation Product Carbon Inventory” has been established and continuously optimized to collect the greenhouse gas emissions of each plant; the Environment, Health and Safety Committee reviews and manages the greenhouse gas emissions on a quarterly basis. ISO 50001(Energy Management System) ISO 14064-1 (Greenhouse Gas Verification Standards) ISO 14067 (International Standards for Product Carbon Footprint) Since 2018, our Taiwan’s plants and China’s plants have promoted the five-year energy management plan (2022-2027) based on ISO 50001, and an annual dynamic review has been conducted based on the status of each plant. The Company continues to pass its annual ISO 50001 system certification. Since 2015, we have promoted the introduction of ISO 14064-1 in all plants, and our Taichung Plant and Yenshui Plant have passed ISO 14064-1 certification. In 2020, our Hsinchuang Plant and Yangmei Plant and in 2022, overseas plants introduced the ISO 14064- 1:2018 standards to conduct internal greenhouse gas emission inventory; In 2024, our Indonesian plants implemented the ISO 14064-1:2018 standard, conducting internal greenhouse gas emissions inventory that received third-party verification. In 2024, our plants in Taiwan and China completed the product carbon footprint self-inventory based on ISO 14067:2018. In 2024, the Hsinchuang Plant continued to have two products pass third-party carbon footprint verification.

Following the ISO 14064:2018 and GHG Protocol standards, and through third-party verification and disclosure, Walsin Lihwa expands its carbon management plan to include its value chain partners. This identifies the most emission-intensive activities within the value chain as a precise guide for emission reduction strategies, also uncovering more opportunities for transformation. In the action plan for 2024, we have established a low-carbon alliance and promoted a sustainable supply chain, working together with our value chain partners to create a sustainable development business model. In our 2024 project of Scope 3 greenhouse gas inventory, we adopted materiality assessment criteria, considering factors such as emission volume, improvement potential, and quantification methods. We identified emissions from upstream raw materials of our purchased products and services, upstream emissions from fuel and energy-related activities, and disclosed a total of 12 items in Scope 3/Categories 3 to 4. Walsin Lihwa continues to collaborate with its value chain partners in developing low-carbon products through strategies such as green product design, jointly combating climate change and global warming with its value chain partners.

The greenhouse gas compilation method is based on the operational control approach. 6. 2014 is the starting year for the Company’s implementation of the energy-saving plan 7. Scope 2 emissions are calculated based on a market-based approach 4. Wastewater treatment: The wastewater from each of Walsin Lihwa's plants has been properly treated and discharged through wastewater treatment facilities in the plant site and the wastewater quality testing has been regularly conducted to avoid the impact of wastewater discharge on the environment. Management at source is most important in water conservation. Based on water quality characteristics, the treatment procedures were designed and recycling units were installed, so the wastewater has been discharged to nearby rivers according to regulations or piped to recycling units in order to effectively use limited water resources. Each plant site has adjusted equipment and process to reduce water consumption and improve wastewater recycling system, so as to enhance the recycling ratio of the process water. The average pollutant concentration in wastewater discharged by the factories in 2024 met the effluent criteria. The recycling ratio of Taiwan plants reached 90% and above. Note: The above figure is sourced from Section 1.3.1 "Use of Water Resources" in our Sustainability Report. 5. Strict control of industrial waste: Business Overview 150 The 4Rs (reduce, reuse, recycle and recovery) have constituted the foundation for Walsin's waste production and control. In 2024, for our plants in Taiwan and China, overall waste recycling rate of copper wire, wire and cable and stainless steel reached 94.43%, of which the non-hazardous waste recycling rate was 98.87%; hazardous waste was 86.81%. Except for some of the waste produced by self-recycling and reuse, the rest are entrusted to qualified manufacturers for removal, treatment or reuse. The output of waste in Taiwan and China factories decreased by 9% compared with 2024; for the Taiwan plants, the overall waste recycling rate of harmful waste increased by 1.22% compared with 2024, mainly because all the waste acid from Yenshui Plant was transported to the Taichung Plant for waste acid treatment and reuse and process improvement and adjustment, thereby reducing the dust collection ash and sludge, and the landfill rate of plants in Taiwan stood at <1% target. Aside from continuing to promote source reduction of waste and recycling of waste in the plant, the Company will, in conjunction with the strength of the supply chains, reduce the amount of raw materials and reduce the harm that production may bring to the environment. The Company has established strict control and auditing mechanisms for waste flow and screening of qualified vendors to ensure that waste flows are proper and legal.

The total amount of non-hazardous waste recycled in the European plants was 7,713 metric tons, while the remaining hazardous and non-hazardous waste was disposed of outside of the plants. 6. Improving energy use efficiency: Walsin Lihwa upholds the business philosophy of "Green Manufacturing, Happy Enterprise and Sustainable Management". In addition to committing to quality management, pollution prevention, environmental protection, safety and health, our company adopts "Enhancing energy efficiency and promoting clean energy" as its energy management guidelines to fulfill its social responsibility in energy conservation and carbon reduction. We aggressively incorporate energy-saving equipment, efficient technologies, environment-friendly facilities and environmental protection designs and green process into promoting improvement of energy efficiency at source. In response to the governments' energy policies and measures, we educate our employees 151 about energy conservation and inventory the energy consumed by equipment and facilities to seek opportunities for improving our energy performance and to also effectively implement our energy saving plans. 7. Energy conservation and carbon reduction: 2015: Established energy conservation and carbon reduction management organizations across all plants, setting annual targets and implementing various energy conservation and carbon reduction measures. Regular meetings were conducted to review progress, and an energy management information platform was established for real-time management. 2021: Planned and installed 5.5 MWp of renewable energy (solar) for self-generation and consumption. The installation was fully completed in 2024, with grid-connected power generation reaching 6,232,988 kWh. 2022: The Environmental, Health and Safety Committee adjusted the five-year energy management plan on a rolling basis, establishing annual targets of 1% electricity savings and 1.5% carbon reduction. 2024: All four plants in Taiwan met the Bureau of Energy, Ministry of Economic Affairs' annual electricity saving rate requirement of 1%, achieving an average electricity saving rate of 1.86%. Taiwan and overseas plants (Asia) jointly proposed 105 carbon reduction initiatives, resulting in a total electricity saving rate of 3.14% and a total carbon reduction of 18,886 MTCo2e per year.

Retirement system: To provide job security to employees, the Company has established a retirement system pursuant to regulatory requirements with specific measures as follow: (1) Established a "Pension Oversight Committee" in 1986, whereby workers' pension funds (which account for 2 % of the total salary payments to all old pension scheme employees) are deposited monthly into a pension account at the Bank of Taiwan. (2) The Company has commissioned external consultants to prepare a pension fund actuarial report annually since 1994 and set aside a pension reserve fund each month based on the actuarial report in order to satisfy pension applications made by employees eligible for retirement. In 2024, NT$5,843,000 was set aside for the pension reserve fund. (3) In line with the implementation of the new pension system in 2005, the company has continued the issuance of the pension fund to retired employees who have elected to receive the pension under the old system. As for employees adopting the new system, 6% of their salary will be monthly withdrawn as retirement pension and deposited into each employee's personal account at Labor Insurance Bureau. Employees may voluntarily contribute within the 6% to satisfy personal demand in retirement preparation based on personal needs. For the year ended December 31, 2024, the amount of NT$325,361,000 that should have been appropriated according to the percentage specified in the defined benefit plan was recognized in the consolidated statement of income of the Company. (4) According to the revisions of the Labor Standards Act in 2015, the Company assesses the balance in the designated labor pension reserve funds account, calculate required labor pension funds for the laborers who meet the legal retire criteria in the follow following year and make up the difference before the end of March the following year. As of the end of 2024, it was estimated that the balance in the labor pension reserve fund account is sufficient to cover the retirement payments for employees expected to meet the legal retirement conditions in 2025. (5) In addition to compliance with the aforementioned retirement regulations and in recognition of the contributions made by retired employees, the company also issues commemorative medals and awards to retired employees. Meanwhile, the Employee Welfare Committee as well as the industry union has also issued retirement souvenirs to fully reflect the company's gratitude towards retired employees. (6) For employees in China, the subsidiaries enroll their employees in pension plans as required by law and make monthly contributions to the pension plans according to the local regulations in order to provide adequate retirement protection for the employees. 6. Employee Code of Conduct: To ensure that employees comply with obligations to the Company, customers, competitors and suppliers during business operations, the Company has established an Employee Code of Conduct in order to regulate employee behavior. The highlights of this Code are as follows: (1) Obligation to the Company: All Company employees must be dedicated, studious, conform to all rules of the Company and ensure confidentiality. (2) Obligation to customers: When conducting business dealings in representation of this Company, the employee's attitude must be humble and without any arrogance or pride lest damaging the Company's image. (3) Obligation to competitors: The Company's employees should gather competitor information to serve as a reference for Company strategy in a legal and open manner.

Atypical Labor Rights Protection: The Company categorizes the employment of atypical labor into two main types: labor dispatch and labor outsourcing. The management of human rights for atypical labor is conducted in accordance with the Company's internal employment management rules and the systems of labor dispatch and labor outsourcing. In addition to overall benefits, such laborers are entitled to the same employment conditions as formal employees of Walsin, and they also enjoy basic protections such as labor and national healthcare insurance. Prior to collaborating with labor dispatch or labor outsourcing vendors, the Company first understands their compliance with labor laws, which serves as the basis for evaluating whether to cooperate. Furthermore, given that the Company's contracts are signed on an annual basis, before each annual contract renewal, the Company voluntarily conducts inquiries, audits, or other necessary actions regarding the legality of the labor conditions of dispatched or outsourced laborers, to ensure that cooperating vendors continuously comply with relevant regulations. (2) Protective measures taken to ensure a safe working environment and maintain employees' personal safety Walsin Lihwa's ESH and energy policy is "Green Manufacturing, Happy Enterprise and Sustainable Management". The health and safety system and administrative measures are as follows: 1. To enhance occupational safety and health management (including fire safety management) and fully implement the Occupational Safety and Health Management System (ISO 45001), the application covers all plants in Taiwan (Hsinchuang, Yangmei, Taichung, Yenshui), mainland China plants (Shanghai Walsin, Jiangyin Alloy, Changshu Walsin, Yantai Walsin), Indonesian plants (PT. Walsin Nickel Industrial Indonesia and PT. Sunny Metal Industry), and CSA, encompassing all workers (employees, contractors, and visitors). The overall coverage rate is 83.97% for employees and 98.86% for non-employees (contractors), excluding Taipei headquarters, PT. Walhsu Metal Industry, Nanjing Walsin (Real Estate), and Walsin Precision in Malaysia, which have not yet passed certification. The Company continues to use the PDCA cycle for dynamic review and improvement, management methods for prevention of recurrence, and internal audits and exercise, and to set and track annual occupational safety and health performance indicators, in a view to enhancing workplace safety for colleagues and establishing a comprehensive and friendly workplace. In terms of safety and health performance indicators, this includes proactive indicators such as key system promotion, support from senior management at each plant, and disclosure of management systems; reactive indicators such as work-related accidents and penalties from competent authorities; and indicators such as the frequency and items of general (special) health examinations. In fire safety performance management, each plant is fully staffed with fire management personnel (firefighters/security supervisors/fire equipment area autonomous management personnel), implements fire equipment maintenance management, and regularly conducts full-staff fire escape drills and fire self-defense organization drills. 2. Designated health and safety and environmental management units or staff Each of Walsin Lihwa's domestic and overseas plants also has its own Occupational Safety and Health Committee (in Taiwan)/Safety Production Committee (in China). Those committees include certain labor representatives to participate in and discuss matters relating to occupational safety and health. The number of labor representatives in the safety and health committees set up in Taiwan factories in accordance with the law are in line with the regulatory requirements. These committees hold meetings every quarter. In addition to the passing down of practical experience and the dissemination of ethical principles in occupational safety, we provide a platform for the exclusive Environmental Safety and Health Committee meeting minutes system and an electronic signature system for quarterly meeting results, and send internal newsletters through the intranet with work-safety-related emails to share our experiences. Note 1: All plants in Taiwan have established Occupational Safety and Health Committees (abbreviated as OSH Committees) in accordance with the law, with the number of labor representatives meeting regulatory requirements. Plants in Mainland China, Malaysia, and Indonesia maintain Safety Production Committees. Plants Total General Members General Members Labor Representatives Meetings Times Labor Percentage Taiwan 102 68 34 28 33.33% China 45 41 4 16 8.89% Malaysia 20 10 10 4 50% Indonesia 24 16 8 16 33.33% Italy 68 41 27 53 39.71% Business Overview 156 Note 2: (1) Percentage = Number of labor representatives/Total committee members × 100%. (2) Taiwan regulations stipulate that labor representatives must constitute at least 1/3 of committee membership; overseas plants have no such requirement. 3. Safe Workplace and Friendly Management In 2024, there were 109 employee work-related injuries (including 1 fatal injury at PT. Walsin Nickel Industrial Indonesia, but excluding 160 minor injuries). The recordable injury rate was 1.02% (number of work injuries as a proportion of total employees). The overall accident frequency was higher than in 2023. Analysis showed that frontline technical operators still had the highest occurrence rate (85%) (This analysis excludes CAS). The primary injury types were entanglement injuries (20%), followed by cuts (15%) and impact injuries (15%). For non-employees, there were 13 work-related injuries (including 2 fatal injuries, but excluding 13 minor injuries). The primary injury types were impact injuries (31%), followed by falls (23%). All related accident risks and deficiencies have been promptly addressed through hardware protection and management measures. In 2024, there were no incidents of fire or chemical leakage across all subsidiaries of the Company. The goal of occupational safety management is to deeply instill safety awareness and knowledge in every worker, forming what is known as a "safety culture." This year, Walsin analyzed workplace accident cases from the past five years (Taiwan and Mainland China regions, 198 cases in total) to facilitate departmental proposal systems and self-management activities (team meetings). This initiative encouraged colleagues to improve workplace hardware and operational procedures. The on-site Safe Job Procedure (SJP) involved operational personnel and team members jointly reviewing existing regulations (126 SOPs), followed by discussions to align with and revise SJP and risk assessments for collective compliance. This approach ensures every worker can participate in work safety discussions and guarantees that employees can understand, remember, and follow the procedures. Although overall injuries increased this year, this project has contributed to a downward trend in the second half of the year. Note 1: Minor injury: refers to the non-temporarily incapacitated state: unable to work on the day of injury, but can resume normal operation the next day. 4. Training on occupational safety and health for workers In addition to legally mandated training, necessary training is conducted based on departmental operations, on-site job types, and the annual safety training plan requirements of the business unit. Regular training plans are also established for environmental and safety responsibilities, fire escape drills, special operation personnel, and emergency response drills, along with a comprehensive environmental and safety certification system in place to keep track of the certification trends and needs of each site. Occupational Safety and Health Educational Training New Recruit Training In-Service Personnel Training (internal training) In-Service Personnel Training (external training, including for license acquisition) Pre-Site Training for Contractors Plants Number of Persons Number of Times Number of Persons Number of Times Number of Persons Number of Times Number of Persons Plants in Taiwan 487 10,238 473 438 188 530 137 Plants in China 272 15,095 120 441 87 1,917 384 Plants in Malaysia 41 150 16 5 5 0 0 Plants in Indonesia 894 4,403 2,246 117 594 456 482 Plants in Italy 492 8,556 935 886 135 559 160 Subtotal 2,186 38,442 3,790 1,887 1,009 3,462 1,163 5. Optimization of Contractor Management All Walsin factories in Taiwan and China implemented the "Walsin Lihwa Contractor Management Principles," with all contractors required to sign the "Environmental, Safety, and Health Commitment" and comply with the "Contractor Instructions" (coverage rate of 100%). Regular kickoff meetings and contractor agreement meetings are held, and contractors must undergo relevant contractor training before they can qualify for entry to the site (or the plant). We manage site contractors' entry/exit information through "Contractor Management System." In 2024, there was a cumulative number of contractor entries at 7,822 (calculated by the number of control cards). All plants continue to implement the "Walsin Lihwa Contractor Safety and Health Management Blue Book," "Standardization of Contractor Safety and Health Management Regulations," "Contractor Insurance Standards," and access control, issuing a total of 704 notices for improvement and 131 penalty tickets for violations. In 2024, there were 2 fatal contractor injuries (1 at Yantai plant and 1 at Yenshui plant), 11 contractor injuries (at CAS), 13 minor injuries (5 at Yantai plant, 2 at Yenshui plant, and 6 at CAS), and 3 near-miss incidents (at CAS), with the related deficiencies immediately rectified, and the focus issues have been promoted. No contractor fires occurred in any work environments at Walsin plants in 2024. 6. Compliance with Occupational Safety and Health Regulations In 2024, there were a total of five significant penalties (with each fine exceeding NT$700,000) for violations of the Occupational Safety and Health Act in the Taiwan Plants. In the Mainland China, Southeast Asia, and Europe Plants, there were no violations with fines exceeding NT$100,000. In response to the relevant violations, we will continue to review each accident and penalty event, as well as high-risk hazardous operations and equipment, high-frequency near miss events by focusing on hidden dangers based on projects, and we will, 157 through information systems, gradually help improve personnel safety awareness, with real-time control of machinery and equipment, (raw) materials and chemicals control, and gradual construction of a regulatory cloud information system, to optimize our occupation, safety, and health management system. In 2024, the Company did not have any fire, explosion, or chemical leakage. Note: The standard for disclosure of major fines is NT$100,000/RMB22,000. 7. Establish friendly, safe and healthy workplace through health promotion (1) Occupational Safety and Health Activity Highlights Employees are the most precious assets of a company, and Walsin Lihwa designs feasible employee health promotion plans every year. The Company conducts health inspections and analysis of results based on risk management, as well as on hazardous operations and special groups of hazardous operations (such as noise, free radiation, dust, high temperature, lead, manganese, nickel, and hexane operations) in the plants, and establishes health protection plans for hazardous operations, to ensure that employees have a good working environment and avoid occupational diseases. In 2024, through health promotion seminars and activities, efforts were made to enhance employees' health awareness and guide them in changing health behaviors and habits, while acquiring correct health knowledge. In 2024, a total of 151 related health education seminars were conducted, with a cumulative participation of 5,562 individuals. Additionally, 12 female employees received maternal labor health protection.

The Yenshui Plant was awarded the 2024 Sports Enterprise Certification by the Sports Administration of the Ministry of Education. (4) Specific Measures and Implementation Results for Chronic Disease Prevention (Obesity, Hypertension, Hyperglycemia, and Hyperlipidemia) in 2024 The Company has implemented the following specific measures to prevent obesity and hypertension, hyperglycemia, and hyperlipidemia among employees: The Company arranges regular health examinations for all employees, achieving a 100% examination rate. For individuals with elevated BMI, abnormal blood pressure, blood sugar, or blood lipids, individual health management files are established. These employees receive one-on-one physician consultations and, when necessary, are referred to professional medical institutions for further treatment. Additionally, the Company invites professional nutritionists to provide health education seminars on healthy eating and organizes activities such as smoking cessation programs, fat and weight reduction initiatives, walking competitions, and core strength building programs. Through these preventive measures, the overall percentage of employees with blood sugar abnormalities decreased from 24.1% to 19.8%, and the percentage of cholesterol abnormalities decreased by 1.5%. The average satisfaction rate for participation in health promotion activities exceeded 92.5%. (3) From the most recent year to the date of publication of this Annual Report, any labor-management disputes and resulting losses suffered by the Company and its countermeasures: None. 6. Information Security Management (1) Describe the risk management framework for information and communications security, information and communications security policies, specific management plans, and resources devoted to information and communications security management.

Exchange Rate Change In 2024, the impact of foreign exchange after hedging operations resulted in approximately NT$20 million in losses.

Based on foreign currency positions, the Company will utilize market instruments (e.g. forward foreign exchange contracts) for hedging purposes. Inflation The Company's products are not for general public consumption therefore inflation has no direct impact on the Company. However, it might raise the Company's demand for working capital. The Company will strictly control the operating cycle and keep track of the source and use of funds.
