I. Letter to Shareholders

Dear Shareholders:

In 2025, the Company reported consolidated revenue of NT$8.467 billion and after-tax profits of NT$2.479 billion. The revenue enjoyed a significant growth of 33%, compared with NT$6.356 billion in 2024; and the after-tax net profit was a huge increase of 35%, compared with NT$1.837 billion in the previous year.

As shown in the consolidated financial statements, the Company's gross profit margin was 58%, operating net profit margin was 35%, after-tax net profit margin was 29%, return on equity was 28%, and return on assets was 22% in 2025. Thus, its overall financial status remains stable and sound.

The main reasons behind the Company's substantial growth in revenue and profits in 2025: (1) The annual revenue of four major product lines (AOI, SPI, X-RAY, and board testing ICT) reached record highs. (2) Revenue and profits in Taiwan and Southeast Asia regions grew significantly, with both reaching historical peaks. (3) Revenues from the server industry and network communications industry have also shown substantial growth. (4) New products were successfully commercialized, and product competitiveness continues to improve. (5) Maintaining close ties with customers and major international manufacturers has driven significant growth in revenue and profits throughout the year.

Future business policy, production and sales policy, development strategy and expected sales volume:

The Company's operating strategy focuses on enhancing the competitiveness and market expansion of its two main equipment categories: Automated Inspection (AOI, SPI, AXI) and board testing ICT. In addition to the continued growth of SMT process testing equipment, semiconductor process testing equipment will play an important strategic role in the future. The proportion of semiconductor testing equipment revenue to overall revenue is expected to increase year by year. Opportunities for future growth lie in (1) The Company's AOI currently ranks first in the global SMT market share. In addition to continuously improving the cost-effectiveness of AOI in the SMT market, it will actively develop semiconductor process inspection equipment, and expects the shipment volume of the AOI equipment to maintain considerable growth. (2) We are strengthening the competitiveness of SPI equipment in the SMT market and are committed to developing equipment for semiconductor process inspection. The shipment volume of SPI machines will continue to grow. (3) X-RAY equipment is an essential inspection device for SMT processes in servers, network communications, and automotive electronics, especially in semiconductor manufacturing, where demand is increasing significantly. The Company will continue to enhance the competitiveness of its X-RAY machines, and expects shipments to continue to grow. (4) Board testing ICT equipment is essential for server, network communication, and automotive electronics processes in SMT manufacturing. In-Line ICT smart manufacturing has become a global trend, and the shipment volume of board testing ICT equipment is expected to continue to grow. Our Company aims to compete with U.S.-based Keysight and Teradyne in the global SMT board testing ICT markets in the future. (5) The Company continues to deepen the application of AI technology on imaging optical machines to reduce program preparation time, while improving the detection rate and reducing the misjudgment rate. (6) To deepen the layout of the global market: With the commercialization of new products and the improvement of product competitiveness, coupled with the booming AI infrastructure construction, we expect a great opportunity for growth in shipments this year.

Influence of external competitive environment, regulatory environment and overall business environment on the Company:

The Company continues to improve its product quality and operational management. The Company's core values are "Team, Speed, Innovation, Integrity, and Service." Meanwhile, the Company will continue to improve its overall competitiveness in "technology leadership", "stable and reliable quality", "global market development", "control of new product development schedule", and "internal talent cultivation". We firmly believe the Company will have opportunities for continued growth.

We would like to express our deep gratitude to all shareholders for their support, which enables the Company to continue to grow.

We wish you all good health and happiness.

Chairman: Chieh-Yuan,Chen Manager: Chieh-Yuan,Chen Accounting Chief: Kaun-Yuan, Chen

3. Board diversity and independence:

(1) Board diversity: The Company advocates and respects the policy of director diversity. As an attempt to strengthen corporate governance and promote the sound development of the composition and structure of the Board of Directors, it is believed that the diversity policy will help improve the overall performance of the Company. The election of board members is based on the principle of employing talents and abilities, and on diversified and complementary capabilities across industries to include basic composition (age, gender, and nationality, for example.), industry experience and related skills (finance, securities, accounting, law, education, and electronic technology, etc.), business judgment, business management, leadership decision-making, and crisis management capabilities. To reinforce the functions of the Board of Directors and achieve the ideal goals of corporate governance, Article 20 of the Company's "Corporate Governance Code" clearly states that the board as a whole should have the following capabilities: 1. Business judgment ability 2. Accounting and financial analysis ability 3. Operation and management ability 4. Crisis handling ability 5.Industry knowledge 6. International market outlook 7. Leadership and 8. Decision-making.

The Company’s diversity policy of current board members and implementation is illustrated as follows:

(2) The Board of Directors’ specific management objectives of diversity policy and achievements:

Managementgoals	Achievements

exceed three sessions.
Sufficientprofessional knowledge and skills	Achieved

Note: The current nine directors were elected at the Shareholders’ Meeting held on May 31, 2023. There is only one female director, less

than one-third. This is because the composition of the Board of Directors mainly considers the professional background, experience, participation and contribution of the candidates to the future development of the Company, and does not specifically limit the gender ratio. To promote gender equality on the Board, a long-term goal of one-third of directors being of different genders will be set, and progress on this diversity will be reviewed regularly.

(3) Board independence: The Company's Board of Directors consists of 9 directors, including 4 independent directors, accounting for 1/3 of the board seats, and none of them has served three terms. The number of directors with employee status does not exceed 1/3 of the board seats; there is no family relationship between all directors and independent directors as defined in Article 26-3, Paragraph 3 of the Securities and Exchange Act. In addition, in accordance with the "Regulations Governing Appointment of Independent Directors and Compliance Matters for Public Companies", all independent directors have issued an "Independent Director Statement" when they were elected, confirming that they meet the independence qualification requirements.

			 To promote ISO14001 environmental management system, continue energy conservation and carbon reduction activities, create sustainable environmental resources, and fulfill the corporate social responsibility of sustainable environmental maintenance.  To introduce ISO45001 Occupational Safety and Health Management System, and provide a safe and hygienic workplace environment to ensure the rights and interests of employees.  To provide competitive rewards, creating a workplace environment for employees to learn and grow. Let employees grow with the Company and form a high-quality corporate culture.  To be dedicated in social welfare, and the Company and employees participate in activities to give back to the society.

			and fulfill the corporate social responsibility in this regard. In addition, it also obtained the external certification of ISO45001 occupational safety and hygiene management system. This is to provide a safe and hygienic workplace environment, to ensure the rights and interests of employees and a safe working environment In 2025, as in previous years, we sponsored the Taipei Family Service Center to hold a winter carnival to assist disadvantaged families. We also collaborated with the Taiwan Public Welfare League to donate resources for the disaster relief efforts in the Matai'an River in Hualien. In addition, we donated related supplies to Pingtung County Yutian Elementary School Baseball Team, Tainan City Hongjia Rehabilitation Shelter Center, Taoyuan City LOHAS Orphanage, and Taoyuan Teacher Chang Foundation, thereby providing tangible assistance and doing our part to protect vulnerable groups. Meanwhile, the Company continues to encourage employees to give back to society by offering annual "compensation leave for doing public service." In 2025, a total of 115 employees applied to participate in public services. Taking the "2025 blood donation drive" as an example, the amount of blood donated reached 35,250cc, setting a new record. Other charitable projects and activities include community beach cleanups and volunteer work with the Taiwan Rabbit Saving Association. This year, we continued our collaboration with World Vision Taiwan on the "Red Envelopes Convey Love" and "It's your turn to be Santa Claus" events. TRI hopes that children can grow up healthily and learn happily, bringing warmth to them and their families. Our staff also received feedback cards from the children, encouragingeach other and continuingour commitment to "givingback to

This year, we responded to the invitation from Hwa Ya Technology Park to participate in the "Planting Trees for a Shared Future" event and independently organized the "North Coast Baisha Bay Employee Beach Cleanup” activity. We also participated in the E.SUN Financial Holding's "ESG Sustainability Initiative" campaign. We hope to demonstrate our determination to save energy and reduce carbon emissions through these concrete actions and contribute to environmental protection. In 2025, we continued our collaboration with professional organizations to provide EAPs (Employee Assistance Programs) to help employees stabilize their emotions and manage stress. We held monthly birthday parties and organized "Quarterly Afternoon Tea" events (referring to special festivals such as the first day of work, Labor Day, Ghost Festival, and Winter Solstice) to increase employees' connection with traditional culture and to reward their hard work. In addition, this year's health promotion activity, "Step by Step to Success, Enjoying Slimmer Life," invited external speakers to the Company to share healthy eating and weight loss tips.

4.1.2 Industry Overview

1. Current situation and development of the industry:

The automatic inspection w is mainly used to accurately check and indicate the defective parts from the circuit board. Since there are dozens of or even hundreds of electronic parts on the circuit board, the problem such as missed insertion, wrong insertion, cold welding or part fault may occur during the manual or automatic insertion welding. If it relies on manual inspection, it is time-consuming and unreliable, which further affects the efficiency of the production process. The automatic detection equipment solves the aforementioned problems related to defects, reduces the defects found before shipment which may result in rework. Therefore, it is an indispensable detection assistant for the industries such as electronic information and communications in the production process. In recent years, assembly production lines have been faced with requirements for higher yield and output speed, which brings higher market demands for automatic inspection equipment and the stricter requirements for functionality. This will help equipment suppliers with high price / function ratio and fast R & D speed to seize more business opportunities.

The automatic inspection equipment can be divided into ICT, AOI, SPI and AXI based on the functions:

A. In-Circuit Tester (ICT):

Besides static tests, it can only test the digital function of the IC on the circuit board. With the external power supply, it uses the PXI module on the test equipment to measure the analog and digital signals on the circuit board, which is applied to the quality inspection before shipment of the finished products. It belongs to dynamic functional test. It is suitable for products with complex circuit board design, many test points and powerful electronic components, such as automotive electronics, servers, etc.

B. Automated Optical Inspection (AOI):
Due to the compact and slim design trend of information and communication products, it makes the circuit board testing technology more difficult. AOI uses optical image scanning / reading technology to replace general visual or traditional probe test. It solves the blind spots of the test for the assembled circuit board due to high distribution density of electronic components, such as skew, tombstone, lifted lead, scratches, polarity, excessive solder, insufficient solder, and etc.
C. Solder Paste Inspection (SPI):
SMT quality is determined by how to improve the printing quality of solder paste. The SPI can quickly measure the thickness and open/short circuit of each solder point, so as to solve the long-term troubles that 2D cannot solve. For compact and slim products, it won’t cause poor contact due to small solder points, insufficient solder, vibration when use, thermal expansion and contraction, so as to improve the quality and capacity of the process.
D. Automated X-ray Inspection (AXI):
For the traditional electrical measurement methods that adopt probe implanting, due to the high density of PCB parts, it is quite difficult to implant probes, so the test coverage is greatly reduced. The AOI system that uses visible light as the inspection light source cannot provide effective and satisfactory test coverage in high-density parts, micro parts, shielding solder joints of RF and high-frequency circuits, and etc. Through the good penetration and non-destructive inspection characteristics of X-Ray, it can be combined with traditional AOI systems to greatly improve the overall system test coverage.

2. Correlation between the industrial upstream, midstream and downstream

The components needed for manufacturing and assembling the automatic inspection equipment of the Company are mostly purchased from major domestic manufacturers, such as: XY Table, image processing board CCD Camera and X-ray tube, instrument table, PC board, IC, press and computer. After the above-mentioned components are obtained, the Company processes, assembles and inspects them, and finally sells them to manufacturers of information, communications and other industries, which are used to inspect and test the components during its production process, so as to improve the production yield.

The correlation between the industrial upstream, midstream and downstream is shown as below:

3. Product development trend:

In recent years, technology products are developing towards the compact and slim trend. All manufacturers of mobile phones, digital cameras, LCD screens, and laptops are fully committed to promoting the slim feature of their products to consumers. In response to the trend of lightweight products, the products must be designed with smaller size while maintaining the original high yield, which is quite difficult. Taiwan’s industry that is dominated by outsourcing, is forced to enter a brand new generation of technology. The manufacturers have invested a lot of funds to update or expand new production lines and purchase more advanced production equipment. In terms of automatic inspection equipment, the growth of the network and the integration of 3C will promote the market demands for automatic inspection equipment. In addition, the rapid growth of communications and portable audio-visual products will bring high market demands for testers with small size and high density of electronic component.

4. Product competition situation:

(1)ICT ：

At present, the manufacturers in Taiwan are mostly OEM, ODM and EMS. As for the inspection equipment, the foreign customers often designate to use products from international large brands. The Company has developed non-multitask models and simplified the jig manufacturing process. The improved human-machine interface makes it easy-to-operate for users. As the circuit boards are getting highly complicated and integrated, the new generation of automatic inspection equipment is provided to replace the equivalent equipment made from foreign manufacturers gradually. Recently, it has obtained a number of European and American AVL certifications, which will be helpful for the product sales and market expansion.

(2)AOI/SPI/AXI ：

At present, there are many foreign competitors related to AOI, SPI and AXI. After investing huge resources in the research and development for many years, the Company has released a comparable machine with well-known foreign manufacturers in terms of the inspection speed and functions. Such machine can fully meet the current strict testing requirements for small components, with extremely high competitiveness in the market. In addition to the miniature trend of electronics, the ICT equipment that originally used electrical testing will face the problem of incomplete testing (low coverage of insufficient testing points). It is expected that the demands for AOI / SPI / AXI equipment will still have growth space in the next several years.

5. Yield rate of the Company’s products:

Under the requirements of the quality policy, "developing advanced technology, pursuing excellent quality, and satisfactory customer service", the Company has been working hard to promote the design and production of high-precision and high-quality measurement equipment that will achieve a win-win outcome with customers. In terms of the quality requirements, it considers the R & D quality, process quality and service quality as the key elements of quality assurance. The Company has also set the installation yield rate, the repeated purchase rate of customers and the number of major factory certifications as the key performance indicators. Through the strategy roadmap, the quality goals are expanded to the entire company, so as to fully promote the implementation of quality. The implementation schemes such as quality verification for products developed, engineering design change process tracking, customer complaint handling, supplier quality counseling, subsidiary quality system linkage, etc. are all in pursuit of the goal of maximum customer satisfaction. Through quality cycles, it achieves continuous improvement and progress to provide customer-oriented quality services. However, under the constant challenge of pursuing better product quality, we are still committed to making breakthroughs. The "Time to Market" is the key in this new economic era. In terms of future efforts: we will strive to accelerate product commercialization, meet new technological challenges, and enhance the confidence in product reliability. We will provide high-quality assurance for our products and the customer's products, which is the Company’s goal in quality.
