Chapter I Letter to Shareholders

Dear Shareholders,

We appreciate the long-term support and trust of all shareholders in Complex Micro Interconnection Co., Ltd. (hereinafter referred to as "the Company") and taking the time to attend the Company's 2026 Annual General Shareholders' Meeting.

Looking back at 2025, the global electronics industry as a whole was still in an adjustment phase, with market demand showing structural divergence. Growth momentum is primarily concentrated in application areas such as AI servers, cloud computing, and high-performance computing. However, the actual penetration rate of the Company's main products—flexible printed circuit boards (FPC) and electronic cables—in these applications remains limited. The overall competition in the FPC and wire material industry remains intense, with most manufacturers prioritizing maintaining production capacity and operational stability.

The Company's consolidated operating revenue for 2025 was NT$2,379,713 thousand, which slightly decreased from the previous year; the net income for the current period was NT$63,759 thousand, with earnings per share (EPS) of NT$0.97. The 2025 Business Results and 2026 Business Plan Overview are reported to the shareholders as follows:

I. 2025 Business Results

(I) Business Plan Implementation Outcome

The overall operational performance in 2025 was mainly affected by factors such as global economic conservatism, changes in tariff policies, and adjustments in the supply chain, resulting in a slight decrease in consolidated operating revenue compared to the previous year. However, the Company continues to optimize its product mix and process efficiency, and the overall gross profit structure remains relatively stable.

In terms of industry sectors, the revenue share of industrial grade products slightly declined due to adjustments in the production bases of certain U.S. customers. However, despite conservative market demand, commercial products continue to promote new customer certifications and the development of new models. For consumer products, successfully securing orders for certain key products has become a relatively stable source of support for the Year.

In terms of capacity layout, the Company continues to promote the establishment of overseas manufacturing bases. The Prachinburi plant in Thailand completed its civil construction and related acceptance processes in 2025 and has entered the equipment installation and mass production preparation stages, laying the foundation for future capacity flexibility and regional supply capability.

The 2025 operating revenue was NT$2,379,713 thousand, a decrease of 2.38% from

NT$2,437,615 thousand in 2024. The gross profit was NT$515,047 thousand, a decrease of 19.35% from NT$638,620 thousand in the previous year. The 2025 basic earnings per share were NT$0.97, a decrease of NT$3.09 from NT$4.06 in 2024.

(II) Budget Implementation Status

The Company and subsidiaries did not make a financial forecast for 2025.

(III) Financial Revenue/Expenditures and Profitability Analysis

Unit: NT$ thousand; %

Item		2025
Financial Revenue/Expenditures	Operating Revenue	2,379,713

	Return on Shareholders' Equity (%)	3.40
	Net Income Before Tax to Paid-in Capital (%)	12.20
	Net Profit Margin (%)	2.68
	Earnings per Share (NT$)	0.97

(IV) Research and Development Status

The Company continues to view R&D as a core source of competitiveness, and the key investment directions for 2025 include:

High-frequency and high-speed technology capability development: Establish a dedicated team and complete the setup of related testing equipment to engage early in the customer design phase and enhance technical adhesion.
Material technology enhancement: Completed flame retardant certifications for multiple material structures of PI, MPI, and LCP, allowing us to provide customers with more flexible solutions based on different frequency and application requirements.
Equipment upgrade: Continuously introduce high-precision processing equipment to strengthen the manufacturing capability of high-density and high-reliability products.

The related R&D results have gradually transformed into collaboration opportunities in new application fields, laying the foundation for the company's mid-term and long-term growth.

II. 2026 Business Plan Overview

(I) Operational Policy

Looking ahead to 2026, the global electronics industry still faces challenges such as

economic uncertainty, tariff policies, and supply chain restructuring, with market demand structure continuing to diverge. The Company will continue to adopt a prudent and pragmatic Operational Policy, focusing on niche application markets with medium to long-term development potential.

Business Plan for FPC Products

In terms of product and technology deployment: The Company will continue to deepen its capabilities in high-frequency, high-speed, high-reliability, and highly customized flexible board products. By engaging early in the customer product design phase and integrating material selection with processing technology, it aims to enhance the technical added value and long-term cooperative relationships.
In terms of application markets: In addition to existing commercial and industrial products, we will continue to invest in new application areas such as smart glasses, medical electronics, and high-end automation equipment. Although the development and certification timeline for such products is longer, their product life cycle is relatively stable, aligning with the company's mid-term and long-term operational strategy.
In terms of capacity and regional layout, in line with the trend of major customers gradually shifting their production bases to Southeast Asia, The Company will use the new plant in Thailand as a second production base. This will form a complementary and supportive capacity configuration with existing sites to enhance delivery stability and supply chain flexibility.

Business Plan for Wires and Cables

In terms of wire products, the Company will continue to adhere to prudent and stable management principles, avoiding pure price competition, and maintaining a reasonable profit level through the automation of production processes and enhancement of quality stability.

For business notebooks and related applications: continue to use the integration design of Wire+FPC as the main strategy for securing orders, enhancing the value of comprehensive solutions.
In terms of battery cables and existing consumer applications: Gradually adjust the customer portfolio to reduce the proportion of highly competitive, low-margin products.
In terms of medium and long-term development direction: Cable products will be oriented towards the non-consumable electronics application markets of medical equipment, automotive-related modules, smart home, and high-end lighting, in order to establish a differentiated competitive advantage.

(II) Sales Volume Forecast and Basis

According to the current industrial environment, major customer order visibility, and capacity allocation planning, it is predicted that the operating revenue for 2026 will grow steadily compared to 2025. Among them, the revenue of the FPC and Wire and Cable Business Units will grow gradually with the increasing volume of new application products and overseas capacity efficiencies.

(III) Important Production Sale Policies

Capacity Layout Policy: Ensure the smooth commissioning of the Thai plant, establishing it as the company's second production base, to enhance the overall supply chain flexibility.
Sales Policy: Deepen overseas customer deployment, expand the bare board delivery model, increase the front-end capacity utilization rate, and reduce the pressure on operating capital.
Supply Chain Management: Strengthen the stability of key raw material and equipment supply to ensure delivery timelines and quality.

III. Impacts of the External Competitive Environment, Legal Environment, and Overall Operating Environment on the Company's Future Development Strategies

(I) Development Strategies:

Continue to promote customer expansion and industry diversification strategies, deepen overseas customer deployment, reduce the risk of business area concentration, and gradually expand the customer base for bare board delivery to increase the utilization rate of front-end flexible board production, while also reducing the pressure on working capital and inventory from the turnkey model. In terms of key industry deployment, we continue to cultivate the market for medical industry boards and wires, while maintaining close cooperation with North American trade partners. At the same time, we target existing EMS customers and opportunities related to high-frequency and high-speed antennas and modules, enhancing the diversity of our product portfolio and the stability of our operations.

(II) External Competitive Environment:

The global flexible board and electronic wire industry competition remains highly intense, with ongoing pressure from price competition and capacity adjustments. The Company will avoid pure price competition, and use quality stability, technical service capability, and flexible delivery as its main competitive advantages.

(III) Regulatory Environment:

In response to increasingly strict environmental protection regulations, climate change-

related requirements, and international accounting standards, the Company has completed an organization-level greenhouse gas inventory and continues to promote carbon management and process optimization to reduce regulatory compliance risks and meet customer ESG expectations.

(IV) Overall Economic Environment:

Overall market demand is still affected by the slowdown in global economic growth, inflationary pressures, and geopolitical risks, with end-use application demand showing divergent development.

In terms of application structure, growth momentum is primarily concentrated in areas with high reliability, high-frequency, high-speed, and highly customized applications. In comparison, the recovery of traditional consumer electronics-related demand remains limited, while market competition continues to intensify. With the increasing demand for thinner products, higher integration, and higher performance, the requirements for FPC and electronic wire in terms of material selection, design capability, and process stability are rising. Meanwhile, the trend of supply chain restructuring and regionalized production continues to develop, with customers gradually increasing their requirements for capacity configuration flexibility and delivery stability. On the cost side, fluctuations in raw materials, energy, and labor costs exert certain pressure on the overall profitability structure.

Overall, the short-term market remains uncertain. However, FPC and electronic wire suppliers with technical capabilities, stable quality, and a foundation of customer cooperation still have room for development in the medium to long term. The Company will continue to prudently respond to changes in the external environment through process optimization, product mix adjustment, and market layout enhancement.

IV. Looking ahead

The competition in the flexible board and electronic wire industry will remain highly intense. Yuan Yu will continue to focus on medical, automotive, high-frequency, high-speed, and new AI terminal applications as key development directions. By deepening technology, upgrading processes, and deploying in international markets, it aims to steadily enhance operational resilience and medium to long-term growth momentum, creating long-term and stable value for shareholders.

Diversity and Independence of the Board of Directors

(1) Diversity of the Board of Directors:

The overall composition of the Board of Directors shall be taken into consideration in the selection of the Company's directors.

The composition of the Board of Directors shall be determined by taking diversity into consideration, and shall establish and formulate an appropriate policy on diversity based on the Company's business operations, operating dynamics, and development needs, and include, but not be limited to, the following two general standards:

A. Basic Requirements and Values: Gender, age, nationality, and culture.

B. Professional Knowledge and Skills: Professional background (e.g., law, accounting, industry, finance, marketing, technology), professional skills, and industry experience.

Each Board member shall have the necessary knowledge, skills, and experience to perform their duties; the abilities that must be present in the Board as a whole are as follows:

(a) Operational judgment ability.
(b) Accounting and financial analysis ability.
(c) Business management ability.
(d) Crisis handling ability.
(e) Knowledge of the Industry.
(f) International Market Perspective.
(g) Leadership.
(h) Decision-making ability.

The current Board of Directors of the Company consists of 9 directors. The specific management objective of the diversity policy of the Board composition and its implementation status are as follows:

Management Objective	Status of Criteria Satisfaction
Directors concurrently who act as managerial officers of the Company shall not exceed half of the total number of directors	Criteria satisfied
Board members consist of at least one female director	Criteria satisfied
Independent directors with a term of office not exceeding three terms	Criteria satisfied
Number of independent directors exceeding one-third of the total number of directors	Criteria satisfied

Implementation status of the Board member diversity policy is as follows:

Director Name	Gender	Age				Seniority of Independent Director	Concurrent Position as Employee of the Company	Diversity Core Abilities
		41-50 years old	51-60 years old	61-70 years old	71-80 years old			Finance	Knowledge of the Industry	Production and Manufacturing	Accounting	Law	International Market Perspective	Business Management

Wan Hsin Ning	Female		✓			1 years		✓			✓		✓	✓

(2) If the Number of Directors of Either Gender is Less than One-Third of the Total Number of Directors, the Reason Therefor and the Measures to be Taken to Improve the Diversity of the Board of Directors:

A. Reason: The Company has nine directors in accordance with the Articles of Incorporation. The current directors were elected in the shareholders' meeting on June 26, 2024. There are two female directors, accounting for less than one-third of the total number of directors. This is due to the characteristics of the industry, which make it hard to find female talent in a short time.
B. Measures to be taken: Before the end of the term of the current

Board of Directors and the election to new directors, the Company will seek recommended talent from the industry or schools to improve the performance of corporate governance and implement the policy of diversity of the Board of Directors.

(3) Independence of the Board of Directors:

The present Board of Directors of the Company consists of nine directors, including four independent directors, accounting for 44% of the present total number of directors. The ratio of directors concurrently acting as employees of the Company is 33%, less than half (inclusive) of the total number of directors. In addition, two directors are in a spousal relationship, which is less than half of the total number of directors. In view of the above, the independence of the Board of Directors has been satisfied.

(2) Board of Directors Performance Evaluation by an External Professional Independent Institution: On December 25, 2024, the Company appointed an external professional independent institution, "Taiwan Corporate Governance Association," to perform the 2024 Board of Directors performance evaluation, which was conducted through a questionnaire survey and on-site visits for five major aspects (the composition and task division of the Board of Directors, the guidance and supervision of the Board of Directors, the authorization and risk management of the Board of Directors, the communication and cooperation of the Board of Directors, and the self-regulation and improvement of the Board of Directors). The evaluation results were reported to the Board of Directors on February 25, 2025.

A. Overall Evaluation:

(a) An election of the Board of Directors of the Company was held in June 2024, with nine directors elected, including five natural person directors and four independent directors. In consideration of gender equality, the Board of Directors includes two female directors. The members of the Board of Directors have professional experience and backgrounds in business management, corporate management, international trade, accounting, and legal affairs; the overall composition of the Board of Directors meets the needs of the Company's business development and strategic goals.
(b) The Company's independent directors have an positive attitude towards their responsibilities, possessing professional knowledge and investing sufficient time. They do not hesitate to ask questions and provide suggestions, and are able to communicate with general directors and the management team smoothly.
(c) To enhance the functions of the Board of Directors, the Company has established the "Regulations for Performance Evaluation of Board of Directors" to implement the self-evaluation of the Board of Directors, directors, and functional committees every year, and submit the evaluation results to the Board of Directors. The Regulations provide that the Company shall be evaluated by an external professional independent institution at least once every three years. This year, the Company commissioned an external professional independent institution to perform the Board of Directors' performance evaluation for the first time, which reflects the Company's admirable intention to improve the performance of the Board of Directors.

B. Suggestions/Improvements:

Item	Suggestions of the Evaluation Report	Measures the Company Plans to Take
1	Valuing the robust corporate development and ethical management, the Company has an "ESG" section set up on the official website, with the "Stakeholders" section thereunder disclosing the information of "Investors/Employees/Suppliers/Customers/Others (Illegal (including corruption) and Unethical Behavior)." In addition, under the "Investors" section, the "Ethical Corporate Management - Reporting Regulations" are disclosed in the "Company Bylaws" under the "Corporate Governance" section, and the "Reporting System/Reporting Channels and Methods" are also available in the "Integrity Management and Ethical Conduct" under the "Corporate Governance" section. However, the direct link to the Board of Directors (particularly independent directors) is important when it comes to a whistleblowing mechanism. It is recommended that the Company consider establishing a complete and clear reporting system with the actual practice taken into account, and with revisions made in accordance with relevant laws and regulations, so that the direct link of all reporting mechanisms to independent directors is reinforced and the anti-corruption whistleblowing mechanism is further strengthened.	The Company plans to set up a reporting mailbox for each independent director (i.e. each member of the Audit Committee) to receive relevant reports in a simultaneous and direct manner according to the suggestion, so that each independent director can monitor the handling status of the reporting and that the effective operation of the whistleblowing mechanism can be ensured.
2	Although the Company provides sufficient resources for independent directors to perform their duties, there is a lack of an official inaugural training mechanism for new directors. To help new directors understand the Company's business condition and strategic development as quickly as possible, it is recommended that the Company consider establishing a "Training System for New Directors" under which the Company's business scope, industrial dynamics, laws and regulations, directors' rights and obligations, as well as continuing education measures are introduced by dedicated personnel, and on-site visits and mandatory courses are arranged, in order to enable the new directors to perform and fulfill their duties as directors right after they take office.	In the future, the Company will make relevant plans and arrangement according to the needs of the new directors, if any.
3	It is recommended that the Company's Remuneration Committee, at least once a term, review and discuss the policies, systems, standards and structures of remuneration to directors and managerial officers, and the system and indicators of the performance evaluation of directors and managerial officers. This helps ensure the consistency with current practices and the benefits of evaluation, thereby enabling the Company to effectively motivating the management team and achieving the goal of sustainable operation.	The responsible unit will give an assessment by reviewing the current relevant operations.

Goals for establishment of and execution status evaluation on the enhancement of the functions of the Board of Directors for the current year and the most recent year:

(1) In order to strengthen corporate governance structure and promote sustainable development, the Company established the "Sustainable Development and Nomination Committee" on February 25, 2025, to assist the Board of Directors in reviewing and advising on matters related to sustainable development and corporate governance policies and systems.
(2) The Board of Directors holds regular meetings to thoroughly discuss and make decisions on important issues such as the company's operational strategies, financial status, major investments, and sustainable development. They also continuously monitor the implementation of board resolutions to enhance the overall operational efficiency of the Board of Directors.

(II) Audit Committee Implementation Status

There were six Audit Committee meetings convened in 2025, and the attendance status of the independent directors is as follows:

Title	Name	Actual Number of Attendances	Number of Attendances by Proxy	Actual Attendance Rate

After the public offering of shares of the Company, the board of directors is authorized such that distributable dividends and bonuses, capital reserve or legal reserve in whole or in part may be distributed in cash after a resolution has been adopted by a majority votes at a board of directors' meeting of the Company attended by more than two-thirds of the total number of directors, which shall also be reported to the shareholders' meeting, and the requirement for resolution of a shareholders' meeting described in the preceding paragraph is not applicable.

The Company's dividend policy is established by the Board of Directors according to the

business plan, investment plan, capital budget, and internal/external environmental changes. Accordingly, the remaining dividend policy is presently adopted, and appropriate dividend distribution is established based on the consideration of the balance of dividends, such that cash dividends shall not be less than 10% of the total amount of dividends.

I. The Company acknowledges that the establishment, implementation, and maintenance of the internal control system is the responsibility of the Board of Directors and managerial officers, and the Company has already established such an internal control system. The purpose of this system is to provide reasonable assurances in terms of business performance, efficiency (including profitability, performance, asset security), reliability, timely and transparent financial reporting, and regulatory compliance.

II. The internal control system has its inherent limitations, and regardless of how perfect the design is, the effectiveness of the internal control system can only provide reasonable assurances to the achievement of the aforementioned three objectives. In addition, due to the change of the environment and circumstances, the effectiveness of the internal control system may be changed. However, the internal control system of the Company is equipped with a self-monitoring mechanism, and the Company will take corrective actions once any deficiency is identified.

III. The Company judges whether the design and implementation of the internal control system is effective based on the criteria for judging the effectiveness of the internal control system set out in the Regulations Governing Establishment of Internal Control Systems by Public Companies (hereinafter referred to as the "Regulations"). The internal control system judgment items under the "Regulations" are divided into five constituent elements as per the management and control process: 1. control environment, 2. risk assessment, 3. control activities, 4. information and communication, and 5. monitoring activities. Each of the elements in turn contains certain audit items. For more information on the aforementioned items, please refer to the "Regulations".

IV. The Company has adopted the aforesaid assessment items for the internal control system to determine whether the design and implementation of the internal control system are effective.

V. Based on the results of the assessment in the preceding paragraph, the Company is of the opinion that, as of December 31, 2025, the internal control system (including the supervision and management of its subsidiaries), including the understanding of the effectiveness of operations and the extent to which efficiency targets are achieved, reliable, timely, and transparent reporting, and compliance with applicable rules and applicable laws and regulations, is effective and can reasonably assure the achievement of the foregoing objectives.

VI. This statement will form the main content of the Company's Annual Report and prospectus and will be made public. Any illegal misrepresentation or non-disclosure in the public statement above is subject to the legal consequences described in Articles 20, 32, 171, and 174 of the Securities and Exchange Act.
