Passion and Confidence

G-TECH Optoelectronics (the "Company") is a professional glass processing manufacturer with comprehensive glass processing technologies capable of satisfying the demands of different markets. The products face competition in various individual technical fields, such as glass cutting, thinning, reinforcement, coating, 3D formation and bonding and lamination. Nevertheless, the Company owns integrated services for all the production processes and is also equipped with collaborative advantages for crossing the barriers of different markets of consumer electronics, factory control, automotive and smart building glass.

With the rise of new technologies such as the internet of things, artificial intelligence and 5G networks, touch screens are constantly being developed for factory control, automobile, smart home, education, healthcare and other various applications, which are exactly the directions for our company's product development. The products extend from glass processing to TP Module services, and the technology applications span across the industrial products, such as in-vehicle, optoelectronics, medical care and construction. Customers were also expanded from LCM and industrial control plant in the early stage to the end customers, such as sports, in-vehicle and buildings.

1. 2025 Business Status Report

(1) Business Implementation Outcome

Unit: NT$ thousand

Operating revenue from products	2025	2024	Amount of increase or decrease	Increase/ decrease
Smart cars	236,315	599,204	-362,889	-60.56%
Smart optoelectronics	1,816,660	1,350,607	466,053	34.51%
Smart buildings	229,772	213,369	16,403	7.69%
Total	2,282,748	2,163,181	119,567	5.53%
Gross profit	-10.53%	1.13%		-11.66%
Net income	-26.49%	-11.12%		-15.37%

The Company's revenue in 2025 increased by NT$120 million compared to 2024, with an increase rate of 5.53%, mainly due to revenue growth in smart optoelectronics and smart building products of NT$466 million and NT$16 million with increases of 34.51% and 7.69%, respectively. In addition, revenue from smart auto products declined by NT$363 million with a decrease of 60.56%. However, the rise in operating costs has significantly eroded the Company's profit, resulting in a 11.66% decline in gross margin and a 15.37% decline in net profit margin respectively in 2025 compared to 2024.

(2) Budget implementation status

Since the Company has not publicly disclosed the 2025 financial forecast, it is not required to disclose the budget implementation status.

(3) Financial income and expenditure management and profitability analysis

In 2025, although the Company's revenue increased, its operating costs faced significant challenges from global economic and political risks. The Company has actively adjusted its product structure, increased the proportion of sales from niche products, and expanded to lower-cost operating locations. Furthermore, inventory and reducing expenses have also been controlled rigorously to lower operating costs. The Company has also conducted a cash capital increase to increase the working capital and to meet operational needs, such that the Company's financial structure has been improved.

Research and development (R&D)

The Company is committed to the development of own technologies and to improve production efficiency and product quality. We have also obtained U.S. patents for display cover glass in 2025. The main R&D results and plans are as follows:

Year	No.	R&D result and plan	Description of benefits
2025	1	Development of ultra-large-size 3D molding equipment	Product technology for the maximum formation length of 1800mm
	2	Development of ultra-large-size 3D film coating equipment	Product technology for the maximum film coating length of 1,800mm
	3	Development of 3D five-bending curved surface lamination equipment	Development of new lamination technology, and new product application
	4	Development of film coating technology for 3D five-bending curved surface	Development of AR film coating technology for large-angle bending
2026	1	Manufacturing of 3D high-efficiency thermal formation furnace equipment	High efficiency and energy saving, with reduction of mass production costs
	2	Development of ultra-durable AF film	Improvement of wear resistance of cover glass
	3	Ultra-low flatness (roughness) polishing technology	HDD glass applications

Continuous advancement of major business development

(1) Smart automotive product

More and more global automakers are bypassing first-tier suppliers and contacting second-tier panel manufacturers directly to control the display and cockpit integration. This transformation is mainly driven by cost-effectiveness and faster innovation cycles, as well as adjustments to trade-oriented procurement. G-TECH has transformed from a traditional structural division model to the role for assisting and participating in the development and supply of products. We continue to improve multi-curved surface 3D glass integration technology, and to head towards the application and development of advanced glass thermoforming technology. The design of smart cockpit dashboard requires products to meet

the trend of complex, continuous, and multi-curved panel surfaces, and G-TECH is able to achieve product customization meeting the requirements of large size, curved surface, and integration, aesthetic appearance, simple user interface, and enhanced user experience.

(2) Smart Optoelectronics Products

For the application of glass protection, in addition to consumer electronics, the Company enters the market for AI server storage hard disk glass platters (HDD) and fan-out panel-level packaging (FOPLP) substrate glass by leveraging the Company's R&D experience and production capacity in display and touch panel glass substrates. The platter of traditional magnetic hard disk drives is primarily made of aluminum and glass. As memory capacity increases, aluminum faces limitations; whereas glass offers greater potential of development. For the PMR/HAMR read/write technology, HAMR writing generates temperatures of 400–500°C, and aluminum substrates can only withstand heat up to 290°C, whereas glass substrates can withstand temperatures exceeding 690°C. Consequently, future hard disks for AI servers and larger-capacity drives will primarily use glass platters.

Impacts of the external competition, regulatory environment and overall business environment

Climate change and geopolitical risks remain uncertainties for the global economy, and economic growth is expected to slow down in 2026 compared to 2025. The 2025 economic growth was mainly driven by temporary factors of early trade planning and inventory adjustments, rather than fundamental improvements. As the impact of United States tariffs continue to take effect and the effect of early stocking starts to fade, global demand is expected to slow down significantly. Although the demand for AI-related products provides certain support, the growth of electronics and information and communication products exports will slow down due to the big base effect.

The continuous existence of uncertainties in 2026, the intensified protectionism and the labor supply impact can suppress the economic growth, and the global economic outlook may still face the risk of slow growth. To address the continuous changing global economic situation, the Company has diversified its global presence based on customer needs and product strategies to mitigate geopolitical risks. Such dispersal of production bases can also reduce reliance on any single region and fosters closer collaboration with customers, in order to jointly manage cost pressures stemming from tariffs.

In addition, as global ESG requirements increase and regulations become more rigorous, the Company will continue to integrate sustainable development principles into its operations, and will also closely monitor legal and environmental changes while proactively establishing response strategies, in order to minimize operational risks.

Independence and diversity of the Board of Directors

Policy and objective for diversifying the Board of Directors:

Directors of the Company shall be elected by the candidate nomination system as specified in the Articles of Incorporation and with reference to Article 20 of the Corporate Social Responsibility Best Practice Principles for TWSE/TPEx Listed Companies. The election shall not be subject to gender, age, race and nationality. In addition, professional backgrounds, skills and industrial experience suitable for diversified development of the Company shall be taken into account in the election. To achieve ideal goals of corporate governance, the Board of Directors, as a whole, shall be capable of making judgments, accounting, dealing with financial affairs, carrying out business management, handling crises, mastering industry knowledge, holding international market perspectives, demonstrating leadership skills and making decisions. The Company emphasizes the gender equality of board members, and the goal is to increase the number of female directors by more than 2 seats.

Realization of the objective for keeping the Board of Directors independent and diversified:

The 12th term of the Board of Directors of the Company has 7 members, including 4 independent directors, accounting for 57%. The directors are equipped with the equipped background of businesses, optoelectronics, finance and legal respectively. In addition, they are professional in business management, leadership, decision-making, business judgment, crisis handling, industry knowledge and international market perspectives, etc. Diverse outcomes in complementation have been presented. Presently, the board members are all male directors. In the future, the Company will increase the number of female directors with best effort in order to achieve the goal. Only one board member concurrently acts as the managerial officer of the Company, and the ratio

of director(s) equipped with the employee identity is 14%. In addition, the Audit Committee formed by independent directors replaces the supervisor system. Furthermore, directors of the Company are not in the relationship of spouse or relative within second degree of kinship, such that the independence of exercise of relevant authorities is complied. All board members have the nationality of R.O.C. (Taiwan, and the age range of directors is 51~70 years old.

Note: Following the previous General Manager's retirement on July 31, 2018, the Chairman assumed the concurrent role of General Manager after a prudent evaluation by the Board. This arrangement aimed to enhance operational performance and streamline the communication and execution of Board policies. To further strengthen corporate governance, the Board resolved on March 6, 2026, to appoint Mr. Hung Min-Nan as General Manager. Furthermore, the number of independent directors was increased during the 2023 Board re-election. Currently, independent directors constitute more than half of the Board, and over half of the Board members do not concurrently serve as employees or executives, thereby enhancing Board functions and strengthening oversight effectiveness.

At present, the Company has formulated the following specific measures:

(A) At present, independent directors comprised of financial accounting and industry specialists who can provide industry outlook-related advice and effectively perform accounting supervision functions.
(B) In addition to cooperating with the requirements for continuous education for directors and supervisors every year, directors are also arranged to participate in the annual corporate governance forum in order to enhance the board of directors' performance.

Reason for electing an independent director for 3 terms of office: Huang, Kuo-Shih has acted as the Company's independent director for 3 terms, in

consideration that he is an finance professional, familiar with related laws and regulations, professionally experienced in corporate governance, able to create significant benefits for the Company, still capable of bringing his special skills into play and offering professional opinions on supervision of the Board of Directors in performing his duties as an independent director. Hence, during the election of directors in 2023, CPA Huang, Kuo-Shih was still nominated to act as the Company’s independent director.

Note 2: Spouse or a relative within the second degree of kinship with other executives or directors: The Company's Executive Vice President, Chung, Yu-Hsin, and Chairman Chung, Chih-Ming are first-degree relatives.
Note 3: If the Company chairman, president, or equivalent title holder (top manager) is the same person or a spouse or relative within the first degree of kinship, please explain information related to the reason, rationality, necessity, and corresponding measures (for example, increasing the number of independent directors whereby over half of the directors have never concurrently served as employees or managers):
Following the previous General Manager's retirement on July 31, 2018, the Chairman assumed the concurrent role of General Manager after a prudent evaluation by the Board. This arrangement was intended to enhance operational efficiency and strengthen the execution of Board decisions. To further implement corporate governance standards, the Board resolved on March 6, 2026, to appoint Mr. Hung Min-Nan as the General Manager. Furthermore, to enhance Board functions and oversight, the number of independent directors was increased during the 2023 Board re-election. Currently, independent directors constitute more than half of the Board, and over half of the Board members do not concurrently serve as employees or executives.
At present, the Company has formulated the following specific measures:
(A) At present, independent directors comprised of financial accounting and industry specialists who can provide industry outlook-related advice and effectively perform accounting supervision functions.
(B) In addition to cooperating with the requirements for continuous education for directors and supervisors every year, directors are also arranged to

participate in the annual corporate governance forum in order to enhance the board of directors' performance.

The Articles of Incorporation of the Company also specifies that if the Company makes a profit during the year (the so-called profit refers to the pre-tax profit before the distribution of employee compensation and directors' compensation), no more than 0.1% shall be allocated for directors' remuneration. However, if the Company still has accumulated

losses, profits shall be reserved for making up the accumulated losses first.

The amount paid by the Company to the independent directors includes the director’s remuneration, transportation allowance and director’s compensation. Self-review (or peer review) is performed by the Board of Directors in accordance with the “Regulations for Performance Evaluation of Board of Directors and Functional Committee” of the Company, in order to increase remuneration linkage.

b. President and vice presidents

The remuneration of the president and vice presidents includes salary, employee dividends, employee stock options, and new restricted shares for subscription. Salary standards are based on contributions to the Company and reference to peer standards. The employee dividend distribution standard is based on the Company’s Articles of Incorporation, submitted to the Remuneration Committee for deliberation, and then issued after the proposal has passed the board of directors or shareholders meeting resolution. The issuance standards for employee stock options and new restricted shares for subscription shall be evaluated based on contributions to the Company and its future development. The total remuneration paid to the president and vice presidents in 2025 and 2024 was NT$9,726 thousand and NT$9,831 thousand respectively.

The remuneration of managerial officers is determined according to the “Salary Management Procedure” of the Company and based on the job position, personal function and professional competence along with the consideration of the standard adopted in the same industry. In addition, the personal evaluation result conducted according to the “Performance Evaluation Procedure” is used as the basis and the result is also linked to the Company’s business performance indicators, including department performance, annual revenue of the Company, ESG sustainable development performance result and risk control as the reference items for the change of remuneration.

(B) Correlation between remuneration evaluation and business performance

Relevant remuneration performance evaluation and reasonableness for directors and managerial officers of the Company are reviewed and approved by the Remuneration Committee and the Board of Directors. In addition, the remuneration system is also reviewed according to the actual condition of business and amendments of relevant laws and regulations timely, in order to ensure the competitiveness of the salaries provided by the Company.

For important decisions made by the management of the Company, various risk factors are considered in advance, and the performance of relevant decisions are reflected in the profit status of the Company, in order to control the remuneration of the management and relevant risks. The Company has established the Risk Management Committee, formed by all business units, and reporting the risk management implementation result to the Audit Committee

Its purpose is to reasonably ensure operation effectiveness and efficiency (including profit, performance, safeguarding asset security, etc.), report reliability, timeliness and transparency and compliance with the relevant laws and regulations.

II. An internal control system has its inherent limitations.

Control environment, 2. Risk assessment, 3. Control activities, 4. Information and communications, and 5. Monitoring activities. Each component also includes several items. Please refer to the “Regulations” for the aforementioned items.

IV. The Company has adopted the aforesaid internal control system judgment items in order to evaluate the design and implementation effectiveness of the internal control system.

V. The preceding evaluation results indicated that the Company’s internal control system (including the supervision and management of subsidiaries), including the operation effectiveness and the extent to which the efficiency goals are achieved for the reporting system as well as the reliability, timeliness, transparency and compliance with the

relevant laws and regulations for the design and execution of the internal control system, are effective as of December 31, 2025 and can reasonably ensure the achievement of the aforementioned objectives.

VI. This declaration shall serve as the main content of the Company’s annual report and prospectus, and shall be made public. If the aforementioned content contains false statements, concealment, or other illicit matters, the Company shall bear full legal liabilities pursuant to Articles 20, 32, 171, and 174 of the Securities and Exchange Act.

(2) Industry overview

A. Global automotive market

The global hydrogen internal combustion engine (ICE) market scale is expected to grow from US$1.85 billion in 2024 to US$5.9 billion by 2033, with a compound annual growth rate (CAGR) of 13.73% from 2026 to 2033. However, ICE vehicle sales in Europe has declined rapidly, but plug-in hybrid electric vehicle (PHEV) sales show rapid growth. Although China had a larger base of ICE vehicles, its adoption rate of new energy vehicles still leads the world. In North America, especially the United States, ICE vehicle sales will remain at the highest level before 2030, and new energy vehicle growth is prominent. By 2030, the three major markets will demonstrate a rapid decline in fuel vehicle sales and a corresponding rise in electric vehicle adoption despite their varying speeds, which highlights the regional nature of the transformation occurring in the global automotive market. New energy vehicles include battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), fuel cell electric vehicles (FCEVs), and range-extended electric vehicles (EREVs).

From 2024 to 2030, the market share of non-luxury new energy vehicles in Europe is expected to increase from 11% to 16% for the global luxury car market. However, luxury cars continue to hold the larger share with continuous growth. As for the North America, luxury electric vehicles are the key focus in the market. In 2024, each of the categories of luxury and non-luxury pure electric vehicles in China accounted for approximately 25% of the market respectively, creating a relatively balanced situation. However, non-luxury brands had a larger share in other hybrid vehicle models, demonstrating a multi-layered structural difference within the Chinese market.

C. Corporate/AI server storage hard disk glass platters

The platter of traditional magnetic hard disk drives is primarily made of aluminum and glass. As memory capacity increases, aluminum faces limitations; whereas glass offers greater potential of development. For the

PMR/HAMR read/write technology, HAMR writing generates temperatures of $400 - 500^{\circ}\mathrm{C}$ , and aluminum substrates can only withstand heat up to $290^{\circ}\mathrm{C}$ whereas glass substrates can withstand temperatures exceeding $690^{\circ}\mathrm{C}$ . Consequently, future hard disks for AI servers and larger-capacity drives will primarily use glass platters. Demand for enterprise-class / AI servers has grown rapidly, and 3.5-inch hard disk drives (HDDs) maintain a cost advantage over solid-state drives (SSDs), with demand increasing year over year. Currently, capacity constraints within the oligopolistic supply chain are significant, and the market is estimated to reach 35 million units per month.

A. Description of significant changes: (For those with a change of over 20% before and after, and the amount of change reached NT$10 million)
(A) Decrease in gross profit: The decrease in demand for high value-added products in 2025 has led to a decrease in the utilization rate of the plant and an increase in costs.
(B) Increase in operating expenses: mainly due to the increase in the cost of sample development projects and related travel expenses.
(C) Decrease in non-operating revenue: It was mainly due to the decrease of NT$49 million in facility rental income and the gain of NT$34 million from the appraisal of investment properties.
(D) Increase in non-operating expenses: It was mainly due to higher initial setup costs for the Vietnam plant.
(E) Decrease in income tax expense: The recognition of deferred income tax benefits in 2025 was mainly due to the high likelihood of the sale of investment properties after the balance sheet date, resulting in the recognition of a portion of deferred income tax assets based on anticipated future tax deductions.
B. The impact of significant changes: None

(3) Expected sales volume and supporting basis, possible impact on the Company's future financial businesses, and response plans

The Company's products continue to focus on the automotive market and smart optoelectronics as key areas for expansion according to expected sales plans and global market demand. Apart from the automotive products, for the application of glass protection, in addition to consumer electronics, the Company enters the market for AI server storage hard disk glass platters (HDD) and fan-out panel-level packaging (FOPLP) substrate glass by leveraging the Company's R&D experience and production capacity in display and touch panel glass substrates.

Although revenue in 2025 and up to the present day has exceeded expectations, the

US trade war has caused the customer demand to slow down, leading to a significant increase in inventory costs and delaying the mass production and delivery schedule for automotive glass. Furthermore, rising costs for building materials, combined with price pressure from competitors, and ongoing government housing policies have resulted in labor shortages and project delays, causing operations to fall short of projections.

It is expected smart vehicle product sales will indicate significant growth according to the customer orders, and after the production capacity of production lines of the Vietnam Plant increases in 2026. The revenue is also expected to grow after the increase of the production capacity. Smart photoelectric products will be continuously and stably supplied in 2026. Additionally, the Company is also actively pursuing orders for glass substrates used in AI server storage hard disk drives (HDDs) and fan-out panel-level packaging (FOPLP) substrates. For smart buildings, due to the low-price competition among the industry peers, revenue is expected to increase for outsourcing trade transactions, resulting in improved profit margins.

The Company has proactively addressed changes in global market demand and rising tariff costs by enhancing cost and expense controls and monetizing underutilized assets, in order to achieve positive net cash flow from operating activities.

VI. Analysis and evaluation of risks in the most recent years and as of the publication date of the annual report

(1) The effects that recent annual interest, exchange, fluctuation, and inflation rates have had on the profit and loss of the Company, as well as the future response measures:

A. Interest rate changes:

The Company's interest expenses for the first three quarters of 2024 and 2025 were NT$50,465 thousand and NT$35,028 thousand, respectively, accounting for (42.83)% and (34.44)% of the annual profit (loss) before tax, respectively. The Company has established a sound financial system and excellent credit rating. In order to meet the needs of business expansion, the Company has applied for bank loans to support its operations. The Company's financial units regularly evaluate the borrowing interest rates and maintain good relationships with banks to strive for preferable loan interest rates, in order to reduce interest expenses.

B. Exchange rate fluctuation:

The Company is export-oriented, so exchange rate fluctuation has significant impacts upon the Company's profits and losses. In response to risks of exchange rate fluctuation, the Company will adopt the following countermeasures:

(A) Forward forex hedging trade

Maintain close contact with major correspondent banks and monitor changes in the foreign exchange market at any time in order to fully grasp exchange rate trends, and appropriately adjust foreign currency positions based on the capital revenue and expenditure status. The relevant risk managers will pay close attention to the exchange rate market dynamics and implement forward forex hedging based on foreign currency exposure changes to reduce the exchange rate risks. Forward forex hedging shall be conducted according to the "Assets Acquisition or Disposal Handling Procedures".

(B) Natural hedging methods

Use the same currency type for supplier purchase payments and customer sales receipts as much as possible to achieve natural hedging and avoid the impact of exchange rate fluctuations.

Comprehensively consider and evaluate future exchange rate trends and factors that may affect the exchange rates before a business or procurement unit makes external quotes, and provide appropriate and reasonable external quotes to prevent adverse effects on the Company's revenue and profit due to exchange rate fluctuations.

C. Inflation:

The Company is part of the manufacturing industry. In response to the production cost increase caused by raw material inflation, energy, and other production factors, the Company is also committed to energy conservation, consumption reduction, yield improvement, and other cost-reducing measures. In addition, the Company has established long-term strategic partnerships with raw material suppliers to reduce the impact that inflation has on the Company's profit and loss. In the future, the Company will continue to work on various cost reduction measures, pay attention to raw material price changes, and take corresponding measures at the appropriate time.

116 -

(2) Policies for high-risk investments, highly leveraged investments, fund lending, endorsement, guarantee and derivative transactions, main reasons for profits or losses and future countermeasures:

The financial operations of the Company are conducted in a conservative and steady manner. The Company doesn't make high-risk or highly leveraged investments. So far, it only lends funds, offers endorsements or guarantees to or conducts financial derivative transactions with its subsidiaries. The Company has formulated the Operating Procedure for Fund Lending to Others, Operating Procedure for Endorsement and Guarantee, and Operating Procedure for Acquisition or Disposal of Assets. Upon prudent evaluation, it takes actions in accordance with the internal control procedures and pertinent rules of the competent authorities.

(3) Future R&D plans and anticipated investments in R&D expenses:

A. Future R&D plans

(A) Development of ultra-large-size 3D molding equipment.
(B) Development of ultra-large-size 3D film coating equipment.
(C) Development of 3D five-bending curved surface lamination equipment.
(D) Development of film coating technology for 3D five-bending curved surface.

B. Expected expenses of R&D investments

To satisfy the demand for highly customized glass processing and to cope with the rapid change of the application market, the Company will focus on the research and innovation in the next year. For 2025, the expected investment in the R&D expenses is approximately NT$14.2 million.

(4) Changes in domestic and foreign important policies and laws upon financial businesses of the Company in the most recent years and countermeasures:

All routine operations of the Company are conducted in compliance with domestic and foreign important policies and laws, without material impacts on the Company. The Company will pay close attention to possible changes in important domestic and foreign policies and laws at all times, evaluate the possible impact on the Company's financial business, and take appropriate measures in advance.

(5) Impacts of technology (including cyber security risks) and industry changes upon financial businesses of the Company and countermeasures:

The Company's information system architecture is established with the data backup mechanism according to its risk level, and the media backup files are transmitted to remote location for preservation and storage. Various simulation tests and emergency response drills for the server room are also implemented. In addition, to allow the information system to be recovered swiftly and successfully in case of occurrence of system damage, and to reduce possible loss and risk, irregular drills are performed to test the system restoration plan, and backup network direct line is also established along with information security protective measures of proper anti-virus software, security firewall setting and server room access control, in order to ensure normal operation and data security of the information system. Up to the printing date of the annual report, there was no technology change (including cyber security risk) or industry change that could cause impact on the finance and business of the Company. The Company will continuously pay close attention to observing and understanding market information. It will inject resources in advance to enhance its research and development. In addition, intensive cooperation will be conducted with upstream and downstream customers, to adjust production lines, product development and corporate resource injection from time to time according to market dynamics. Besides, the Company will properly implement related countermeasures, understand

117 -

market demand and seize opportunities for making profits.

The Company has formulated complete network and computer-related information security protection measures, but with constant changes in technologies and growing demands for cloud network services, the Company is more likely to face malicious network attacks from any external third-party collapsed systems. Apart from formulating specific measures for cyber security, it cooperates with manufacturers to perform irregular drills on vulnerability scanning, information security assessment and email social engineering, to prevent and reduce harms of similar attacks.

(6) Impacts of corporate image change upon corporate crisis management and countermeasures:

The Company consistently adheres to the principle of ethical and professional management, performs social responsibilities, and improves quality and performance. It is committed to maintaining corporate image and complies with related laws and regulations. Up to the printing date of the annual report, no incident has ever negatively impacted the Company's image. In the future, the Company will continue to fulfill its corporate social responsibilities while maximizing the shareholders' rights and interests.

(7) Expected benefits and possible risks of mergers and acquisitions and countermeasures:

At present, the Company has no plans for mergers and acquisitions.

(8) Expected benefits and possible risks of factory expansion and countermeasures:

A. The Company plans to establish a new factory and to purchase machines and equipment in Vietnam based on the consideration of the cluster development of automotive industry supply chain and the relatively lower local production cost. Accordingly, the overall competitiveness of the Group can be increased and the necessary foundation for the planning of global market expansion in the U.S. and Europe can be established, in order to improve the overall business performance of the Group.

B. Possible risks and response measures: The new factory of the Vietnam subsidiary is a production site established to satisfy customer demands, and the main objective is to provide services timely and locally, in order to reduce the orders affected by the impact of the U.S.-China trade war. The greatest operating risk for the new Vietnam factory is expected to be the production capacity. Under the condition where the local infrastructure is not yet complete and mature, and in view of the government's promotion of the southward policy and the increase of investment transferred from the supply chain in China, cost may be increased due to shortage of power and labor. However, the Company has avoided the popular Southern Vietnam area for the investment, such that appropriate adjustment has been made to maintain the labor advantage. Accordingly, the impact of risks on the business operation is minimized.

(9) Centralized risks of procurement or sales and countermeasures:

A. Purchase

The Company is a manufacturer specializing in the R&D, production, and sales of optical glass. Its main products are touch sensing glass, optical coating glass, thinned glass, cover glass, as well as glass trading. Glass substrate is the Company's main raw material. As the Company has adjusted its development strategy in recent years and gradually entered into new fields such as automotive, industrial control, and green building, the Company has also actively sought and established a second supplier mechanism in order to prevent excessive procurement concentration.

B. Sales

In recent years, the Company has implemented product and customer diversification by developing high-quality AR-coated products for medical displays, strategic alliances in the smart building market, and LED coated curtain glass in order to avoid sales concentration risks. No single customer sales accounted for over 30% following the consumer market demand changes and the strategic adjustment of the Group’s development strategy. As such, the Company’s sales concentration risk is still limited.

(10) Impacts of substantial transfer or replacement of directors, supervisors or major shareholders holding more than 10% of shares or equity upon the Company, risks and countermeasures: None.

(11) Impacts of changes in management rights upon the Company, risks and countermeasures: NA.

(12) For the major finalized and pending major litigations, non-litigation or litigations for administrative disputes administrative disputes associated with the Company and its directors, supervisors, presidents, substantive owners or major shareholders holding over 10% of the Company’s shares or affiliates of which the results may have major impacts on the shareholder equity or securities prices, the disputed facts, target amount, commencement date of litigation, main parties concerned and measures taken as of the publication date of the annual report shall be disclosed:

A. Finalized judgments or pending major litigations, non-litigations, or administrative disputes of the Company in the most recent years and as of the publication date of the annual report of which the results may have significant impacts on the shareholder equity or securities prices: None.

B. Finalized judgments or pending litigations, non-litigations, or administrative disputes associated with the Company’s directors, supervisors, or major shareholders holding over 10% of the Company’s shares in the last two years and as of the printing date of the annual report of which the results may have major impacts on the shareholders’ rights or share prices: None.

C. Company’s directors, supervisors, managerial officers and major shareholders with shareholding percentage above 10% and affiliated enterprises being subject to the conditions described in Article 157 of the Securities and Exchange Act in the most recent two years and up to the printing date of the annual report and the current handling status of the Company: None.

(13) Other important risks and countermeasures:

A. High capital and technology intensive industry with large long-term capital needs

The optical glass cutting, edging, polishing, strengthening, thinning, coating, and molding processes require a large number of precision production equipment. Because multi-processes such as preheating, ion exchange, molding, and annealing are required for chemical strengthening, molding, etc., the process time is long, and large-scale mass production equipment and good utilization rates are required to achieve economic scale and meet the huge and fast niche market demand for consumer electronic products. The Company conducts long- and short-term financing with financial institutions in combination with future capital market financing planning in response to long- and short-term funding needs.

B. Smart building glass products are widely used, the market development time is long, and the results do not manifest easily

Smart color-changing glass will replace traditional glass and sun blinds in buildings and residences, especially for smart building indoor compartment

119 -

applications as well as high-end residential and commercial buildings. This product offers a wide range of functions such as penetration rate selection, fast on/off switching, energy-conserving anti-glare control, and offers more privacy and durability. However, building design and construction times are long, and the initial product efficiency does not manifest easily. The Company can combine the supply chain advantages with its strategic partners by forming strategic alliances to significantly shorten the product development period and enhance competitiveness.

C. Light and thin is the trend for electronic products, and new touch panel technology has been adopted by the industry

New touch panel technology has been widely adopted by manufacturers. Compared to the GG (double glass) technology that was used extensively by the market, the chemically strengthened production capacity of the original touch-sensitive glass has been internalized and used for the currently popular 3D forming glass. The yield rate of the new technology is still an important production cost determination factor. In addition, the market for consumer electronics production capacity has gradually become saturated in recent years, and the capital investment and recovery benefits required for technological refinement have been evaluated. The Company will give priority to leveraging the outsourcing supplier capacity and strictly control the economies of scale effect. These efforts can also prevent idle production capacity loss caused by sudden socioeconomic problems, and strive to achieve the best profit for the Company.

VII. Other significant matters: None.
