One. Report to Shareholders

Dear shareholders, ladies, and gentlemen:

I. 2025 Business Overview:

The Company's consolidated revenue for 2025 was NT$7,221.68 million, representing an 8% increase compared to the previous year. The consolidated gross profit amounted to NT$921.32 million, representing a 12% increase, with a gross profit margin of 13%. The consolidated operating income was NT$550.29 million, an increase of 27% from the previous year, with an operating margin of 8%. The consolidated net income after tax was NT$476.98 million, with net income attributable to the owners of the parent amounting to NT$277.97 million. The earnings per share for the year were NT$1.85.

As a result of the current year's operations, the production equipment in the cement business operated steadily, although rising production costs affected profitability. In addition, in the building materials business, market demand for RT-MIX ready-mixed mortar products remained strong, and overall production and sales volumes increased compared to the previous year. Furthermore, the output of the self-developed sustainable material, lightweight microspheres, increased, replacing the previously imported raw materials on which the Company had relied, and the cost benefits have gradually emerged.

In summary, the Company has demonstrated strong operating momentum in its core business. Together with contributions from investment income, overall profitability increased compared to the previous year, demonstrating steady developmental momentum.

II. Budget Achievements

The Company does not disclose its financial forecast for 2025 to public in accordance with the "Regulations Governing the Publication of Financial Forecasts of Public Companies". The budget achievement is, therefore, not applicable.

III. Summary of the 2025 Business Plan

Unit: Tons

Type of product	Production Volume	Shipment Volume
Cement, ground granulated blast furnace slag (GGBS)	660,000~700,000	660,000~700,000
Construction Materials	660,000~700,000	660,000~700,000

IV. Research and Development

The Company will continue its efforts in corporate transformation and investment, aiming to innovate R&D from the customers' perspective, develop high-performance niche products, enhance product competitiveness through differentiation, and create value for both the Company and the industry. In light of global climate change and rising environmental awareness, the Company continues to optimize new cementitious building materials with the aim of achieving energy savings and carbon reduction in building materials. Furthermore, the Company has developed offshore wind power underwater grouting materials, underwater grouting materials for suction bucket foundations, and

thermal mud, positioning itself as a supplier of grouting materials for offshore wind turbine foundations and materials for onshore cable conduits. In addition, leveraging its expertise in wind power mortar technology, the Company has further developed high-flow, ultra-high-strength steel fiber cementitious building materials to meet the requirements of current construction projects.

In addition, to implement the government’s five strategies “Green Growth and 2050 Net Zero Transformation,” regarding carbon reduction in the construction industry, the Company has not only invested in low-carbon cement technology but has also placed greater emphasis on the development and application of green, renewable, eco-friendly, and energy-saving building materials. The Company has successfully developed and produced lightweight microspheres independently, which enable the recycling and reuse of materials, help create circular green buildings, and promote a sustainable, net zero lifestyle. This lays the foundation for sustainability and contributes to gradually achieving the nation’s net zero vision.

V. Future Outlook

(I) Outlook of the Cement Market

As we look ahead to 2026, despite the challenging external economic environment, under the continued promotion of policies such as the National Hope Project and the second energy transition, major domestic public infrastructure projects and plant expansion projects in the high-tech industry are expected to maintain stable development. Overall, the domestic cement market in 2026 is expected to benefit from green energy infrastructure and regional development plans, with demand expected to remain relatively flat compared to 2025.

(II) Market prospect of construction materials

The ready-mixed mortar (RT-MIX) has earned the deep trust of customers. It is expected that in 2026, based on continued improvements in production utilization and stronger R&D efforts, along with the rigid demand for green building materials arising from the government’s Near-Zero Carbon Building Carbon Reduction Flagship Action Plan, market share will further expand, and overall sales volume is expected to maintain steady growth. For the construction materials agency business, in cooperation with the Japanese listed company NIHON FLUSH Wooden Door Production Co., Ltd., the Company has rapidly entered the market by leveraging products that combine quality and performance, together with its comprehensive distribution channel deployment. Going forward, the Company will continue to promote its products and expand its market reach, with the goal of introducing a new brand each year.

In response to the government’s offshore wind power industry strategy, the Company will continue to promote wind power-related products. At the same time, by leveraging ultra-high-performance concrete (UHPC) developed from wind power grouting technology, the Company is well positioned to meet current engineering needs with its excellent seismic resistance and high-strength advantages, and its contribution to profitability is expected to gradually emerge. In addition, the Company’s expanded glass granules manufacturing technology fulfills

social responsibility by assisting the government and industries in properly handling industrial by-products and achieving 100% recycling and reuse. Having successfully replaced imported raw materials for in-house production and use, the product is now officially available for external sale. Going forward, the Company will actively expand market penetration and product applications, enhance overall operating performance, and make substantive contributions to sustainable building.

(III) Outlook of Demand for Interior Renovation and Design

The Company's subsidiaries are committed to providing customers with high-quality interior decoration design and related engineering services. Looking to the future, Taiwanese companies have successively returned to establish their headquarters, and new factories and offices in the high-tech industry are increasing. In addition, large-scale government-led urban renewal projects and incentive policies for dangerous and old buildings have accelerated project implementation, and the overall renovation and engineering market is bound to grow. The Company has also actively participated in joint development projects involving transportation and rail systems, including large-scale developments such as shopping malls, office buildings, and public facilities for high-end residential areas. By integrating aesthetics and sensory experience into the details of design and construction, and by providing high-quality one-stop services, the Company will continue to generate stable profits.

(IV) Influence of External Competition, Legal Environment, and Macro Business Environment

This year, the overall business environment has been filled with uncertainties due to global geopolitical fluctuations and external instability. However, these challenges have also created opportunities for the Company's transformation and growth. In 2026, as the government accelerates the implementation of major infrastructure and regional development projects under the National Hope Project, and actively carries out net-zero building and environmentally sustainable green energy policies, domestic economic recovery is expected to further boost overall industrial momentum. Moreover, the real estate market continues to benefit from strong demand. Together with ongoing plant expansion in the high-tech industry driving demand for surrounding construction, the growth momentum across various business sectors is expected to outperform the previous year and demonstrate a more stable growth trend.

Looking forward to the future, the Company will focus on "R&D, technology, and distribution channels" as the key elements of its operations and maintain steady operating performance in a changing market. We uphold the philosophy of "innovation and change, and conscientiousness in each product." By strengthening the competitiveness of products and services and cultivating core technologies to better meet customer needs, we are committed to becoming the trusted first-choice partner for both the engineering and market sides, living up to the long-term trust and expectations of our shareholders, employees, customers, and suppliers, and moving toward the goal of becoming a world-class construction material company.

I wish all shareholders,

Good health and all the best,

Chairman Mo, Wei-Han

Achievement of Emission Reduction Targets

In 2025, the actual Scope 1 and Scope 2 Greenhouse Gas emissions amounted to 590,625.7066 tons of $\mathrm{CO}{2}\mathrm{e}$, representing a reduction of 55,539.8091 tons of $\mathrm{CO}{2}\mathrm{e}$ compared to the base year. This reflects a $9\%$ decrease in total emissions. With ongoing and active carbon reduction measures, further emission reductions are anticipated.

Note 1: This information shall be disclosed in compliance with the schedule prescribed in the order issued under Article 10, paragraph 2 of the Regulations.

Note 2: The base year shall be the fiscal year in which the greenhouse gas inventory is completed based on the consolidated financial reporting boundary. For example, under the order issued under Article 10, paragraph 2 of the Regulations, a company with capital of NTS10 billion shall complete the inventory for its fiscal 2024 annual consolidated financial report in 2025, so the base year will be 2024. If a company has disclosed its inventory in its consolidated financial report in an earlier year, it may take the earlier fiscal year as its base year. Also, the data for the base year may be calculated based on a single fiscal year or the average of multiple fiscal years.

Note 3: When preparing the disclosure content, the Company may refer to the best practice reference examples on the TWSE Corporate Governance Center website

(4) New Products to be Developed

In light of global climate change and rising environmental awareness, the Company continues to optimize and introduce new cement products that offer energy and carbon reduction benefits. Furthermore, as living standards improve and urban population increases, residential properties are built taller with greater density, making residents more susceptible to noise disturbances that compromise the quality of the residential environment. The Company's soundproof flooring solutions have been favorably received among customers in this regard, which is why more resources will be committed into improving material performance for a better home living experience. Additionally, actively expanding mortar application areas across industries, including high-modulus (high E-value) repair materials for technology facilities, lightweight construction materials, and mortars compatible with automated equipment.

Offshore wind power makes up a significant part of the government's support for green energy. The Company's ShifuGrout U799, a specialized cement for the foundations of offshore wind turbines, has been certified by DNV Business Assurance Co., Ltd. A new type of mortar for offshore wind turbines that works with the SILO system has also been developed.

By reutilizing industrial by-products, the company develops high-value lightweight microsphere materials with properties such as thermal insulation, heat retention, fire resistance, light weight, and sound insulation, expanding into the multifunctional insulation materials market.

In response to ESG considerations related to durability and weather resistance, ultra-high performance concrete (UHPC) has been developed in multiple categories—such as high-modulus (high E-value), bridge-grade, and architectural/decorative types. These UHPC materials not only reduce the use of high-carbon-emission materials like steel reinforcement and conventional concrete, but also extend the service life of structures.

2. Industry Overview

(1) Current Status and Development of the Industry

A. Status quo of cement industry and development prospects:

Cement is the material for infrastructure in life. Government public constructions and private constructions all need a great deal of cement. It is a mature industry with steady demand. The cement industry in Taiwan is characterized as: capital intensive, domestic sales-oriented, fundamental for daily

life and national defense, and an industry involving continuous production and manufacturing.

Clinker kilns that are currently in operation carry a total capacity of 20.24 million tons. According to the statistics published by the Taiwan Cement Manufacturers' Association, registered members produced 9.98 million tons of cement in total in Taiwan, and imported 3.81 million tons of cement from abroad in 2025; 13.80 million tons of cement were consumed domestically while 0.11 million tons were exported for the year. On average, every person consumed approximately 592 kg of cement each year.

B. Current state and prospect of ready-mix concrete materials:

Finishing works are an important step that prepares a building for renovation. Similar to foundation in facial makeup, the quality of finishing works can directly affect how a consumer perceives a building. Traditionally, workers would store sand and cement at the work site and mix them by experience, which in turn leads to inconsistency in the quality of work materials and the final finish. Ready-mix solutions aim to address this problem by premixing dry sand, cement, and special additives in precise ratios that are suitable for a particular application and requirements right from the factory. These solutions can then be packaged and delivered to the work site, and used by workers simply by adding water to the mix. Ready-mix solutions ensure the consistency of materials, which not only eliminates uncertainties of the actual work but also improves tidiness of the work site and quality of the finish.

Use of ready-mix concrete has increased progressively since it was first introduced in the 1990s. The Chinese National Standards (CNS) introduced a chapter on ready-mix concrete in November 2021, whereas the public construction guidelines also added rules on ready-mix concrete in November 2014, which help establish ready-mix concrete as the dominant solution for finishing works. As consumers become more aware of work quality, ready-mix materials are gradually replacing the conventional cement-and-sand mix, and should grow in popularity with time.

Currently, in the ready-mixed mortar materials market, RT.MIX products hold a market share of over 50%, making it a leading brand in the sector. As market penetration continues to increase, RT.MIX's shipment volume is expected to grow accordingly. In addition, the Company is actively expanding the application scope of mortar across various industries (such as high E-value repair materials for high-tech facilities, lightweight construction materials, and mortars compatible with automated equipment), thereby broadening its product portfolio. Meanwhile, in response to the gradual increase in production and sales demand, RT.MIX leverages its proprietary formulation technology and process improvements to maximize the utilization of river sand resources, reducing waste and optimizing production capacity to meet customer needs.

C. Interior renovation and design:

Interior renovation and design covers a broad spectrum of scenarios from elevator lobbies, common facilities, landscaping, reception spaces, showrooms, and living spaces in a residential development to commercial spaces such as offices, headquarter buildings, office-factory complexes, hotels, malls, supermarkets, libraries, etc.

The demand in the interior decoration industry extends beyond new construction projects. Generally, the renovation cycle for commercial spaces is

~117~

around 3 to 5 years, while for public buildings, it ranges from 10 to 15 years. Additional demand arises based on changes in functional usage. Therefore, the construction decoration industry exhibits characteristics of regular cycles and maintains stable growth.

(2) Relationship Between the Upstream, Midstream, and Downstream Sectors of the Industry

(3) Product Development Trends

In addition to cement products, the Company also makes processed products containing cement. Cement is one of the products used for industrial purposes, and is provided to concrete premixing plants in compliance with performance specified in national standards. Cement products are not only steady and highly reliable in terms of quality, reduced consumption of energy during production and raw material replacement are also emerging to become the future goals. In terms of reduced consumption of energy during production, in the future, efforts will be focused on precise use of energy/CO $_2$ output trial calculation, introduction of high-performance grinding aid solutions, and introduction of alternative fuels, among others. In addition, as far as raw material replacement is concerned, the type of alternative raw materials shall be established, and laws and regulations allowing such replacement, practices, and benefits shall be confirmed. The development as a whole is aimed at integrating environmental protection and energy conservation, and processing and re-utilizing business byproducts, taking care of both the capital threshold and policy trends. Future development is explained in the chart below.

As for product development not under standard regulations, the focus in the future will be LOHAS products and development of construction techniques and machinery. Such LOHAS products include cement products that can prevent radiation, regulate humidity, are sterile, and can keep warm along with construction machinery in order to lead on the market.

Subsidiary - Ruentex Interior Design is a medium-sized interior renovation service company with a comprehensive organization. It mainly undertakes large projects that require a high degree of integration, such as: elevator lobbies, common facilities, and landscaping in residential developments; malls, offices, and laboratories where seamless integration is of utmost importance; and overall planning of electrical, air conditioning, and fire safety systems. Interior renovation services will undergo the following changes in order to better satisfy customers' needs and grow market presence:

A. Status quo of cement industry and development prospects:

Cement manufacturers will gradually transition into the circular economy and environmental protection. The rotary kiln used in the production of cement operates at $1500^{\circ}\mathrm{C}$, a temperature that can be used to treat industrial waste. The Company is actively exploring the possibility of using the heat from rotary kilns to treat slag from blast furnaces, and turn it into alternative materials for cement production. Doing so will help reduce production cost and increase profitability.

B. Ready-mix Cement Materials:

The Company sells ready-mix concrete materials under the brand "RT.MIX"; it is currently the largest manufacturer of dry mortar mix in Taiwan, and has the highest degree of vertical integration among local manufacturers. In August 2013, the Company constructed a fully automated dry mortar mix factory in Dongshan, Yilan, that produces goods with high precision and full automation from materials mixing to the final packaging. The Dongshan Plant is indicative of the Company's ability to incorporate the latest cement technologies and integrate the supply of raw materials to produce at the optimal quality, consistency, and capacity, which in turn reduces production cost by a significant degree and improves market competitiveness. In 2021, a new RT.MIX plant was constructed in Ligang, Pingtung, to better serve and reach customers in Central and Southern Taiwan.

The Company devotes significant resources into innovative research and development, and takes the initiative to explore customers' needs and develop new products that meet their needs. The Company hires researchers from various fields of expertise who have committed themselves to developing high-performance products as well as LOHAS solutions that offer safety, convenience, comfort, health, and energy-saving benefits from customers' perspectives. This R&D capacity is what distinguishes the Company from the rest of the competition.

Due to the absence of minimum capital requirements for registration in the interior design and renovation industry, barriers to entry are relatively low. This has attracted many independent designers and decorators to establish their own studios. Coupled with the creativity of these operators—who tailor innovative spatial design aesthetics to meet clients’ practical needs—the industry has become highly competitive and diverse.

Looking ahead, increasing regulatory compliance requirements will necessitate closer collaboration with professional engineering firms. At the same time, with the advent of the new retail era, the transformation of traditional stores—combined with hybrid business models—has become a prevailing trend. Many businesses are adopting entirely new concepts, such as concept stores and experiential retail spaces, to drive growth. This indicates that the renovation market offers greater opportunities than before and is expected to generate more business potential.

However, stricter regulatory compliance and the growing complexity of integrating design and construction will raise entry barriers for interior design and renovation firms, thereby reshaping the competitive and cooperative dynamics within the industry.

II. Market, Production, and Sales Overview

Market Analysis

(1) Locations where products are mainly sold

The main market for cement products is located in Northern Taiwan, which the Company has an exceptional transportation advantage in due to close proximity.

Yilan, Keelung, Taipei, Taoyuan, and Hsinchu make up the majority of the cement market.

Ready-mix concrete, on the other hand, is sold nationwide and to offshore islands, whereas interior renovation services are also provided nationwide.

(2) Market Share

A. Cement

According to the statistics published by the Taiwan Cement Manufacturers' Association, Taiwan consumed 13.80 million tons of cement in 2025 while the Company sold 776,000 tons of cement (including ready-mix concrete) during the year, representing a local market share of 5.6%.

B. Cement-related construction materials

Currently, most of the mortar used in construction in Taiwan is mixed on-site. There is no industry association for this type of cement use, and no objective data can be obtained to calculate the Company's market share relative to the production value of the entire industry.

In addition to operating proprietary distribution channels, the Company has also been working with wholesale and retail partners nationwide in recent years to diversify the means by which products are marketed. Significant attention has also

~135~

been placed on adopting new sales models and building the brand image as a way to increase market share.

C. Interior Renovation and Design:

Interior renovation and design service covers a broad range of property types from general residences, luxury homes, office-factory complexes, laboratories, libraries, and malls to offices, and businesses involved in this line of profession generally specialize in a few areas. Market share calculated using one general market data is not representative of the reality, and we find it impossible to calculate the market share of Ruentex Interior Design on a comparable basis. Ruentex Interior Design has been receiving an increasing number of invitations to take part in projects, and the satisfaction and recommendations of its customers are indicative of the exceptional workmanship and quality delivered by the subsidiary.

(3) Future Supply and Demand and Growth of the Market

A. Cement

In 2025, the domestic cement market was generally flat overall. Although the government continues to promote forward-looking infrastructure projects, urban renewal, transportation construction, Taiwan-based companies' reshoring investments, expansion of IT and semiconductor manufacturing facilities, as well as new green energy projects such as solar and wind power, which all support cement demand growth, demand from the residential real estate market has gradually declined these years. In comparison with the same period in 2025, the Company's cement shipments in the first quarter showed a slight decrease. Overall, however, the domestic cement market in 2026 is expected to remain stable.

B. Cement-related construction materials

Ready-mix concrete is gradually replacing the conventional cement-and-sand mix as users become more demanding of work quality and try to minimize quality differences caused by human judgment. In November 2011, the government announced national standards for ready-mix concrete (CNS 15517 and CNS 15518) that industry participants must follow, and since then, a number of new innovations have been introduced to bring new value into the product. The Company expects demand for ready-mix concrete to grow progressively in the future.

In recent years, the real estate market has slowed, with developers gradually reducing the number of new projects. RT.MIX, a cement product used primarily during the renovation phase of new construction projects, has increased its market share year after year. As a result, despite a decrease in new project launches in recent years, it continues to benefit from work on sites that began two years ago. The annual sales volume of premixed mortar (RT.MIX) for 2025 is expected to remain steady growth.

C. Interior Renovation and Design:

(2) Future response strategies (including improvement measures) and possible expenses (including possible losses due to absence of response strategies, estimated amount of penalties and compensation, etc.; provide explanation if amounts can not be reasonably estimated):

The Company has complied with the penalty disposition issued by the Environmental Protection Bureau of Yilan County and has paid the fine. The corresponding corrective and preventive measures for the identified regulatory non-compliances are as follows:

Daily scheduled inspections of roads outside the plant area are conducted. If any pollution is detected, immediate manual cleaning and water spraying are carried out to ensure roadway cleanliness.
A comprehensive internal inspection of the electrostatic precipitators (A001, A002) is performed to confirm that internal plates and discharge electrodes are free from dust accumulation or damage, ensuring optimal dust collection efficiency under proper operating pressure.
The efficiency of the electrostatic precipitators (EP) is enhanced to reduce exceedance occurrences. The abnormality handling procedure has been revised: when a single opacity reading exceeds 10%, operators must immediately adjust process parameters and complete documentation to prevent cumulative exceedance beyond regulatory limits.
Training on “Waste Recycling Reporting Practices” is provided to relevant personnel and management, emphasizing that even waste sources exempt from online reporting must maintain proper operational records in accordance with regulations.
Odor control inspections are conducted on preheater and duct connections to prevent fugitive emissions from gaps. In addition, certified third-party odor testing reports (meeting the standard of <1,600) will be submitted to the Environmental Protection Bureau for record.
Inspection of filter bags is strengthened to check for damage, detachment, or improper installation. All aged filter bags will be replaced, and certified particulate emission test reports (<30 mg/Nm³) will also be submitted to the Environmental Protection Bureau for record.
A professional environmental consulting firm has been engaged to assess capacity expansion needs. In accordance with the Regulations Governing the Installation and Operation Permit for Stationary Pollution Sources, an application for permit amendment will be submitted to the

~149~

Yilan County Environmental Protection Bureau to increase the approved annual production capacity of dry-mix cement mortar to reflect actual operational conditions.

A multi-level alert system has been established within the internal management system. Dedicated personnel are required to complete data verification and preliminary transmission by the 10th of each month, providing a 5-day buffer period to mitigate risks from network issues or system failures.
Describe the current state of pollution and how improvements may affect the Company's earnings, competitiveness, and capital expenditure; estimate major capital expenditures on environmental protection in the next two years:

The Company and its subsidiaries have no material environmental capital expenditure plans for the next two years. Currently, emissions from all plants (including air emissions, wastewater, and waste) strictly comply with applicable environmental regulations in the respective jurisdictions. Regular monitoring is conducted through independent third-party testing agencies, and all test results are within regulatory standards. After evaluation, the existing equipment is deemed sufficient to meet both regulatory requirements and production capacity needs over the next two years. Accordingly, no significant additional environmental capital expenditures are expected.

V. Labor Relationship

(2) Training and Education for Employees

Every year we plan pre-job and on-the-job training budgets for employees to improve their professional skills, leadership, and career development. We also encourage them to actively improve their knowledge and participate in external training courses, giving incentives for employees to obtain certification and actively participate in continuing education.

(3) Retirement system

The Company has established a defined benefit retirement plan in accordance with the Labor Standards Act, applicable to all employed foreign mid-level technical personnel. For employees who meet the retirement eligibility criteria, pension benefits are calculated based on years of service and the average salary over the six months prior to retirement. For service years of 15 years or less (inclusive), two units are granted for each year of service; for service exceeding 15 years, one unit is granted for each additional year of service, with a maximum accumulation of 45 units. The Company contributes 2% of total monthly salaries to a retirement fund, which is deposited in a dedicated account under the supervision of the Labor Retirement Reserve Supervisory Committee at Bank of Taiwan.

In addition, at the end of each fiscal year, the Company estimates the balance of the labor retirement reserve account. If the balance is insufficient to cover the estimated retirement benefits of employees expected to qualify for retirement in the following year, the Company will make a lump-sum contribution for the shortfall by the end of March of the following year. In 2025, the Company recognized expenses of NT$157 thousand for the defined benefit plan (old labor pension scheme).

The Company also has a defined contribution retirement plan established in accordance with the Labor Pension Act, applicable to domestic employees. For employees who elect to participate in the labor pension system under the Act, the Company contributes 6% of monthly salaries to each employee's individual account with the Bureau of Labor Insurance. Pension payments are made based on the accumulated contributions and investment returns in the employee's account, either as monthly pensions or lump-sum payments. In 2025, the Company recognized expenses of NT$18,819 thousand for the defined contribution plan (new labor pension scheme).

Conditions for voluntary retirement application:

Investment Plans for the Next Year: None.

VI. Risk Analysis and Assessment (the previous year until the date of report publication)

Influence on income of changes in interest rate and exchange rate volatility and inflation, and future countermeasures:

(1) Interest Rate Changes:

A. Impact on the Company’s Earnings

The Company and subsidiaries reported NT$(60,470) thousand and NT$(84,670) thousand of net income (expenses) for 2024 and 2025, representing 14.66% and 15.71% of profit (loss) before tax in the respective years. Interest rate changes apparently have some impact on the Company’s profitability.

B. Response Measures

The Company and subsidiaries monitor bank borrowing rates on a regular basis and maintain good relationships with banks to make sure that loans are drawn at more favorable rates, and thereby reduce interest expenses. Changes in market interest rates are also monitored constantly to facilitate proper responses.

(2) Exchange Rate Changes:

A. Impact of Exchange Rate Variation on the Company’s Profitability

~161~

The Company and subsidiaries sell primarily to the domestic market, and all revenues are denominated in NTD. Due to a lack of locally produced energy products, the Company sources the majority of its raw materials and fuel from abroad, and these transactions are denominated in USD. Aside from the above, the Company also purchases machinery parts from Europe. Net gains (losses) on currency exchange was reported at NT$88 thousand for 2024 and NT$(5) thousand for 2025, representing 0% and 0% of net revenue and 0.02% and 0% of profit (loss) before tax in the respective years. The effect of exchange rate variation on profitability of the Company and subsidiaries is deemed insignificant; nevertheless, the Company will continue monitoring changes in the USD rate out of conservatism and respond accordingly.

B. Response Measures

a. Observe how the global economy affects exchange rate variation, and develop hedging practices where necessary.
b. Plan foreign currency requirements in advance, and gradually reduce the minimum position for reduced costs.
c. The Finance Department will maintain close relationships with financial institutions and make flexible adjustments to foreign currency positions by observing exchange rate changes.

(3) Inflation:

The Company pays constant attention to fluctuations of raw material prices, and maintains good interactions with suppliers and customers to facilitate forecasting of raw material costs and minimize the effect of price changes. The Company will examine changes in the cost of raw materials regularly, and raise selling prices when changes exceed the predetermined tolerance, and thereby transfer price risks while at the same time prevent significant inflation impacts on the Company and subsidiaries.

Policies, main reason(s) for profits or losses, and future countermeasures for engaging in high-risk and high-leverage investments, lending, offering guarantees and endorsements, and derivatives investments:

The Company and subsidiaries have always adopted a pragmatic focus toward its core business and formulated financial policies out of conservatism. The organization does not engage in high-risk or highly leveraged investments. All external party lending, endorsements, guarantees, and derivative trading are executed according to the "External Party Lending Procedures", "Endorsement/Guarantee Policy", and "Asset Acquisition and Disposal Procedures". Should the Company decide to establish

~162~

a derivative trading policy in the future, one will be created out of conservatism solely for the purpose of avoiding exchange rate risks.

Future Research and Development Plans and Projected Expenses:

The Company previously had two R&D units created to support its main business activities; these units were responsible for exploring improvements to cement and construction materials. In an attempt to secure innovation as a competitive advantage over peers, the Company expanded its existing R&D organization and created an Innovation R&D Center for more effective integration of available resources.

The Innovation R&D Center will aim to recruit master’s and doctoral degree holders, focus on problem-solving through teamwork, and develop new products and technologies for improved competitiveness. The R&D Center will also introduce a new talent development plan with stage-by-stage training to help employees develop the R&D capacity needed to shorten the product development timeline.

The R&D Center will implement performance indicators and manage accordingly to increase productivity and production value and reduce the learning curve for the R&D team. These performance indicators will be associated with the compensation and personnel management system in ways that improve production capacity and value of R&D personnel and contribute to overall management performance.

The Innovation R&D Center will focus on the development of new energy and carbon reduction technologies, green building materials, and high-end granulation techniques, whereas laboratories featuring advanced production equipment and testing facilities will also be constructed as part of the Innovation R&D Center. With new technologies and better system integration, the Company hopes to create new values for its products and strengthen competitiveness within the industry.

(1) Future R&D Plans

A. Cement Business:

As far as national standards are concerned, products of the Company can be distinguished into two categories: those that conform with national standards and where the R&D efforts focus primarily on maintaining quality and saving costs; and those without national standards where the R&D efforts focus mainly on creating demand. R&D resources will be allocated to cater for a balance between the two.

With regards to cost-saving projects, the Company will aim to make use of alternative materials and fuel, and turn industrial by-products into resources through the use of pre-processing and post-processing equipment, as doing so will yield cost reduction as well as environmental protection benefits.

Taiheiyo Cement from Japan, for example, uses industrial by-products that make up 45% of all raw materials and renewable energy that makes up 46% of

~163~

total fuel in production activities. Mainland China, too, is currently developing environmental protection policies that make use of cement kilns for urban waste treatment. Taiwan, on the other hand, produces a great variety yet small quantity of limestone sludge, sludge from water treatment, stone sludge, etc. that pose major environmental concerns if improperly disposed of. These concerns remain unresolved due to technological and policy restrictions.

Cement rotary kilns burn up at to $1,500^{\circ}\mathrm{C}$, a temperature that effectively disintegrates industrial by-products, and its ability to smelt hard-to-treat heavy metals into cement makes it the ultimate treatment facility for industrial by-products. In the future, the Company will look for alternative industrial by-products such as: furnace slag for steel milling, oxidizing slag, reductive slag, etc. and turn them into vital materials and fuel by applying appropriate pre-/post-treatments. Doing so not only reduces the cost of cement production, but also contributes to environmental protection, and is a solution that caters to sustainability and profitability at the same time.

In 2025, in alignment with the government's circular economy and energy-saving and carbon-reduction policies, the company will continue to steadily incorporate industrial by-products as alternative raw materials for cement. To address the impact of introducing these by-products into the cement system equipment, system improvements and equipment upgrades have been completed. Furthermore, in 2025, efforts will expand to include the use of industrial by-products as alternative fuels, along with related trial operations. The initial target for the fuel substitution rate is set at $3\%$.

The production of expanded glass granules, and the Company has so far acquired information on the supply of by-products for expanded glass granules, developed a formula for lightweight aggregates involving a diverse variety and sources of by-products, developed streamlined production procedures, established quality control points and standards, and obtained adequate know-how and a database on reuse of residual heat for production of expanded glass granules as well as production of lightweight aggregates. From 2022 to 2023, the Company will transform the production and manufacturing technology researched and developed independently into the planned expanded glass granules production line, and complete the construction of the factory in the second half of 2023. In the first half of 2024, trial operations of the equipment were completed, including equipment adjustments and production grinding processes. Mass production parameters for expanded glass granules were established. In the second half of 2024, formal mass production of the expanded glass granules products commenced. In 2025, the Company successfully

~164~

developed a roller compaction granulation technology, enabling adjustable control over the particle size distribution of expanded glass granules. Through precise control of semi-finished material granulation size, the Company is able to accurately produce products that meet market specifications, achieving a technological breakthrough in centralized production of target-specification products.

In 2026, the Company plans to establish a recycling and reprocessing system and related equipment for process by-products. By implementing this system, it aims to optimize mass production balance. In parallel, adjustments to rotary kiln sintering parameters are being planned to enhance expanded glass granules production capacity while effectively reducing unit power consumption, thereby achieving the dual objectives of increased output and energy efficiency.

As for the application of expanded glass granules, the Company uses expanded glass granules as the main raw material and combines them with various types of cement to prepare different functional expanded glass granules boards for various market applications. This functional board not only retains the characteristics of low density, low thermal conductivity, and fire resistance of expanded glass granules, but also gains functions such as cutting, drilling, shaping, and water permeability. Further, according to the market demand, it can be applied to various projects such as building lightweight, thermal insulation, thermal insulation, fire prevention, explosion-proof and so on. The initial application is aimed at the development of expanded glass granules boards. By combining inorganic cementitious materials (gypsum, fire-proof mortar, high-alumina cement, etc.), the development of related boards with heat insulation, fire prevention, explosion-proof features, etc. The initial goal is to develop raw materials that can replace current commercial products. With the advantages of expanded glass granules as an environmentally friendly material, we will gradually expand the application of expanded glass granules downstream to increase the added value of existing products. In this way, the expanded glass granules can not only be used in the domestic and foreign markets for the original insulation mortar, but also further encourage downstream manufacturers of domestic related applied boards to replace the imported materials with expanded glass granules, reduce the cost of raw materials, improve the internal competitiveness of the industry. In addition, expanded glass granules possess a unique closed-cell pore structure. The porous nature of the expanded glass granules, combined with elastic damping materials, forms an elastic porous structure that provides sound insulation, sound absorption, and vibration damping. This makes them suitable for reducing impact noise on floors. In 2024, testing

~165~

and certification were conducted in accordance with CNS 15160-8 and CNS 8465-2 standards at a TAF-accredited laboratory. After the installation of polished quartz tiles, the $\Delta Lw$ (impact sound improvement index) was measured at $25\mathrm{dB}$, effectively suppressing low-frequency noise. In 2025, the “expanded glass granules sound-insulating flooring” successfully obtained the High-Performance Green Building Material Label from Taiwan’s Ministry of the Interior and entered the commercialization stage, with simultaneous implementation and field testing in the Group’s construction projects. Meanwhile, the R&D team developed a fireproof coating material for steel-structure buildings. By leveraging the expanded glass granules’ high thermal resistance, excellent fireproof properties, and low water absorption, this material effectively replaces traditional vermiculite. The technology not only complies with fire-resistance rating requirements but also significantly improves spray coverage per unit area and construction efficiency, opening up new application possibilities.

In 2026, we will continue to advance this technology by applying precise gradation of expanded glass granules with different particle sizes and dense packing theory to further optimize fireproof performance. While maintaining safety and quality standards, we aim to reduce the required coating thickness to enhance the competitiveness of expanded glass granules materials, and actively complete validation through real-site implementation.

RT.MIX is the leading brand of ready-mix concrete, and we try to differentiate our products from competitors through ongoing research, development, innovation, and technological enhancement. Emphases of our R&D efforts are as follows:

a. Optimization of Existing Products: Ongoing improvements will be made to the current product line with respect to transportability, workability, and ability to be incorporated with subsequent works.

b. Development of New Products: New products and customized products such as industrial floor panels, outdoor self-leveling cement, indoor colored floor panels, rubber-based soundproof floor panels, C2 tile adhesives for long duration works, adhesives for autoclaved lightweight concrete blocks, low efflorescence adhesives, and soundproof concrete will be developed to support the needs of ongoing works and customers.

c. In response to challenges such as declining birth rates and labor shortages at construction sites, we are developing a masonry mortar compatible with semi-mechanized construction. This mortar enables efficient application and significantly enhances the quality of finished work. Furthermore, it can be

further optimized for integration with AI-powered masonry robots, supporting the advancement toward fully automated robotic construction.

d. The government actively promotes green energy as a way to reduce dependence on fossil fuels and drive growth of the nation's green energy industry. Given the abundance of wind flowing along the Taiwan Strait, many are optimistic about the potential of offshore wind power as a viable power source for Taiwan. The Company's ShifuGrout U799, a specialized cement for the foundations of offshore wind turbines, has been certified by DNV Business Assurance Co., Ltd., and will be marketed to offshore wind power contractors in Taiwan and overseas in the future. The Company has already begun development of ShifuGrout U769, another specialized cement for the foundations of offshore wind turbines, that works with the SILO system and different tools for better work efficiency. The Company has also developed thermal grout for HDD pipes that connect subsea cables to land cables, which has the ability to transfer heat from cables into the soil. The ShifuGrout T508 series is already used in subsea pipes for offshore wind farms.

e. The application and development of Ultra-High Performance Concrete (UHPC) are primarily driven by its formula design, which provides extremely high elastic modulus and high compressive strength, making it suitable for structural engineering applications with stringent vibration control requirements. This is especially true for high-precision technological factories, which have a critical need for micro-vibration control, and UHPC demonstrates unique structural performance advantages in these settings.

Traditional concrete typically has a lower elastic modulus (25–35 GPa), often requiring larger cross-sections or additional steel reinforcement to achieve the desired results. In contrast, using UHPC significantly enhances floor rigidity and changes vibration frequencies without increasing or even reducing structural dimensions. As a result, it effectively reduces the impact of micro-vibrations caused by ground traffic, mechanical vibrations, and nearby construction activities. Currently, the company's technology has developed UHPC with an elastic modulus of 50–60 GPa, making it an ideal building material for future high-precision technological factories and advanced production lines.

Aligned with the government's policy of promoting new materials, Steel Fiber Reinforced Ultra-High Performance Concrete (SF-UHPC) has excellent mechanical performance and durability characteristics, making it particularly suitable for use in national highway bridge projects. The company's SF-UHPC

~167~

technology development not only provides a compressive strength exceeding 140 MPa (20,000 pounds) but also demonstrates significant ductility and strain-hardening behavior, allowing it to withstand larger deformations and loads in tension without brittle failure. This significantly enhances concrete's crack resistance and toughness, making it especially useful for bridge structural systems and joint areas on bridge decks. This new material also offers excellent construction performance, such as high flowability and self-compaction, which helps improve construction quality and reduce project timelines. Despite higher initial costs, it demonstrates good economic benefits over its lifecycle, with long-term durability and low maintenance requirements.

f. The development of a high-performance release agent addresses the growing use of aluminum formwork in casting applications. Due to the alkaline nature of cement slurry, it readily causes corrosion when in contact with metal molds such as aluminum, leading to sticking issues and difficulty in demolding. This often results in poor surface quality of the finished panels, as well as significant cost losses and material consumption due to damage to aluminum and other metal molds. In response, the Company has developed a high-performance release agent that effectively prevents the corrosive interaction between concrete slurry and the surface of aluminum formwork. It can be applied via spraying or coating processes to achieve higher construction efficiency, and its performance is not affected by climate or temperature conditions. This solution significantly reduces the risk of poor demolding and lowers the cost and time associated with mold damage and replacement, while also ensuring optimal surface quality of the finished panels after demolding.
