Diversity and independence of the Board

(1) Diversity of the Board:

According to Article 23 of the "Corporate Governance Best Practice Principles" of the Company, the Board of the Company shall direct the strategy of the Company, supervise the management, and accountable to the Company and the Shareholders Meeting. The plans and arrangement pertinent to the corporate governance system of the Company shall be able to assure the Board in compliance with applicable legal rules, the Articles of Incorporation of the Company, or the resolutions of the Shareholders Meeting in performing its function. The Board shall consist of at least 5 seats of Directors appropriate for the job with reference to the scale of corporate development and the shareholding of dominant shareholders, and the needs in actual operation.

Diversity shall be taken into account in organizing the Board. Directors who also assume managerial positions of the Company should not account for more than 1/3 of the members of the Board. The policy of diversity shall also be in place relevant with the function of the Board, the mode of operation, and development need, and shall include without limitation to the following 2 major aspects of criteria:

a. Fundamental condition and value: gender, age, nationality and education.
b. Professional knowledge and skills: professional background (such as law, accounting, industry, finance, marketing or technology), professional skills, and industry experience.

Members of the Board shall be disciplined with the knowledge, skills, and accomplishment in their respective areas of expertise. For achieving the objective of corporate governance, the Board in general shall be capacity of the following:

a. Judgement in operation.
b. Accounting and financial analysis
c. Corporate management

d. Crisis management
e. Industry knowledge
f. International view of market
g. Leadership
h. Decision-making

The members of the Board will be organized by the Chairman under authorization of the Board on the basis of corporate development need for the suitable candidates.

The expected goals are as follows:

a. The short-term goal of independent director seats should account for 1/3 of all director seats which has been achieved, and the long-term goal is adjusted to 1/2.
b. Directors' diversified background expertise (excluding independent directors/part-time managers) should be judged by taking the enterprise business background as 1/4, financial venture capital background as 1/4, special industry research background as 1/4 and ESG/TCFD and other relevant backgrounds as 1/4.
c. The long-term goal is to increase the number of female Director from the current two to three or four.
d. Directors who concurrently serve as the manager of the Company should not exceed 1/3 of the Board seats.
e. Independent Directors have a term of no more than 3 terms, and each Independent Director cannot concurrently serve as an Independent Director of more than 3 other companies.
f. To cultivate successors for Board members and reduce the average age to 55 to 65 years old.

The current implementation situation is as follows:

a. Diversified background of the Directors (including Independent Directors): Except for 3 directors who actually participate in the operation of the company (including subsidiaries), all other Directors (including Independent Directors) are professionals from outside of whom 4 have corporate management background, 2 are specialized in industry research, 1 has law professional background and 1 is a professor of finance and economics. This meets the goal of appointing Directors who have diversified background expertise. The Company expects to appoint more professional talents from different backgrounds during the re-election in 2027.
b. The Company has recruited three female independent directors (one of whom, Yu-Fen, Lin, resigned on June 14, 2024 due to personal reasons). Although we have not achieved a ratio of more than one-third for either gender, the number of female directors has increased from one in the previous term to three. In the future, we will actively seek suitable female director candidates, increase the number of female directors, and continue to achieve this goal.
c. Age: The age of the Directors (including Independent Directors) in current term of the Board: 3 are older than the age of 70, 6 are at the age of 60~70, and 1 is at the age of 50~60. The average age falls within the range of 65 to 70 years old.

Industry Outlooks and Prospect:

IEKCQM's research reports that the expansion of AI applications in 2025 is generating new opportunities for the electronic components industry. AI application is driving a new wave of end-product hardware upgrades, leading to a significant surge in demand on electronic components. According to IEK projections, Taiwan's electronic components sector is expected to generate NT$2.22 trillion in production value by 2025 with a projected 3.7% YoY growth. This suggests that the AI-driven hardware upgrades will be the industry's main source of growth.

Global supply chains are undergoing restructuring and reallocation due to geopolitical issues. Consequently, production capacity layout and supply chain risk management have become critical imperatives for enterprises. With "China Plus One" still the priority, businesses are shifting operations to Southeast Asia and India. U.S. policy remains the wildcard for 2025: expansion of "Made in USA" policies or technology restrictions will force a further reassessment of global supply chain layouts.

AI development is also reshaping the logic of electronic product design. AI servers are transforming computing, transmission, and cooling. High-speed data transmission needs are upgrading high-frequency PCB and ABF substrate technologies, while high energy density is making liquid cooling and heat-resistant materials crucial components. The rapid emergence of AI edge devices (AI PCs,

109 -

smartphones, and wearables) is accelerating the demand for high-performance and low-power components.

In terms of sustainable development, carbon reduction has become the basic requirement for supply partnerships. Major international manufacturers, including Apple, have formulated carbon reduction targets, prompting the entire supply chain to place greater emphasis on carbon reduction planning. Electronic component manufacturers need to introduce renewable energy, optimize process energy consumption, and establish carbon management mechanisms to bolster their competitiveness within the green supply chain.

The association between the upstream, midstream and downstream industries:

(1) Medical Health:

The global market of medical devices

According to a recent report by Fortune Business Insights, the global medical device market is set to expand steadily from US$572.3 billion in 2025 at a compound annual growth rate (CAGR) of 6.5%, reaching a projected US$886.7 billion by 2032. A 6.5% CAGR might seem moderate; however, in the medical sector, this signifies consistent and sustained expansion, which is precisely the quality long-term investors are looking for.

Research from Topology Research Institute (TRI) indicates that the global EV market (comprising hybrids, plug-in hybrids (PHEV), battery electric (BEV), fuel cell, and extended-range electric vehicles (EREV)) will continue to expand in 2025. Total sales are forecasted at 26.87 million units, with a YoY growth rate of 23.2%. China dominates global EV sales with a 54% market share, driving the global electrification shift. The U.S. market grew by approximately 18% YoY in 2024, reflecting recent policy shifts. With only 15% growth in 2025, the U.S. is a rare outlier experiencing a slowdown. In contrast, Western Europe's growth has outpaced the global average, driving the broader European market forward.

IEA statistics reveal that by 2025, one-quarter of all new cars sold globally are electric (BEVs & PHEVs), marking a fivefold increase in market penetration over the past five years.

China's trade-in subsidies stimulated sales in 2025, yet the annual growth slowed down to 23.4% YoY, compared to 37.7% in 2024. Key factors behind the growth trend include economic pressures from U.S.-China trade tensions, the tapering of government incentives, and the challenge of achieving deeper market penetration. Despite easing domestic growth, China's new energy vehicle (NEV) exports surged in 2025, reaching 2.65 million units with a 54% YoY increase.

In 2025, the overall European NEV market has experienced a

112 -

recovery phase. With a more mature supply chain and renewed government incentives in certain countries, Western Europe's EV sales grew by 26.8% YoY, outperforming the global average of 25.4%.

In the U.S., Hybrid Electric Vehicles (HEVs) became the dominant form of powertrain in 2025. This growth was fueled by the Trump administration's policy adjustments prioritizing internal combustion engines (ICE) over electrification. Coupled with gaps in charging infrastructure, U.S. HEV sales grew by 28% YoY, higher than the global average of 17%, and became the market's dominant technology. With Battery Electric Vehicles (BEVs) sales growth stalling at just 3% YoY, the market has reached a standstill. This stagnation is affecting investments in charging infrastructure by relevant industry players. As Tesla strengthens its hold on the core BEV market, other U.S. automakers face limited market opportunities.

In terms of BEV brand market share in 2025, BYD and Tesla accounted for approximately 12.3% and 8.9%, respectively. If including PHEV, BYD's total NEV market share is even higher, reaching 22~23%.

Three key EV market trends in 2025

According to the IEA (International Energy Agency) and TrendForce, three global EV market trends are as follows:

Entering a phase of "differentiated growth:" Global NEV sales are projected to exceed 20 million units, though regional performances remain highly fragmented. China is expected to see EV penetration exceed ICE vehicles for the first time. U.S. growth is moderating amid policy shifts, while Europe fluctuates under the pressure of subsidy reductions and new emission regulations.

The strong rebound of hybrid technologies (PHEV/EREV): Concerns over driving distance and insufficient charging infrastructure have pushed growth rates for PHEVs and EREVs

113 -

above those of BEVs in several markets, making them a preferred transitional choice for ICE vehicle owners.

Chinese brands dominate supply chain integration and global exports: With BYD firmly at the top, Chinese automakers are capitalizing on their massive scale and cost-efficient battery technology to accelerate growth in Southeast Asia and Latin America, consistently outperforming traditional automakers in market share.
