ROE

Review of FY2025

In FY2025, we posted the highest operating income since the Group’s formation in 1998. Although consolidated net sales increased only 1.1% year on year to ¥896.3 billion, operating income rose 37.7% to ¥77.7 billion, substantially exceeding the prior year. The main drivers were the successful price revisions in domestic cement and lower production costs due to a decline in coal prices. Return on equity (ROE) improved to 9.5%, and the operating income margin reached 8.7%, demonstrating better capital efficiency. Overseas, despite a demand slowdown in the U.S. and the delayed commissioning of the new line

in the Philippines, our focus on appropriate pricing and cost reductions led overseas subsidiaries to achieve higher sales and profits: net sales of ¥344.8 billion and operating income of

¥38.4 billion.

Amid these results, we steadily executed growth investments, including acquisitions of aggregates and ready-mixed concrete businesses in the U.S., while maintaining financial soundness with a net D/E ratio (net DER) of 0.49x.

Outlook for FY2026

For FY2026, we forecast net sales of ¥950.0 billion, operating income of ¥85.0 billion, and net income of ¥60.0 billion, a second consecutive year of record earnings. While domestic cement demand is assumed to decline to 31.0 million tonnes, we expect to absorb higher fixed costs in our domestic cement business through continued realization of appropriate prices. Production volume will also be supported by the cement sales business acquired from Denka Co., Ltd. (to be reflected from 1H FY2026) and by higher exports of blended cement that help maintain high plant utilization, leading to higher sales and profit in domestic cement. In overseas cement business, we project higher sales but lower operating income year on year, taking into account the demand slowdown in the U.S.

and tariff risks. Although U.S. nationwide demand is expected to edge down slightly, we anticipate higher sales volumes for both cement and ready-mixed concrete, reflecting the year-end acquisitions of aggregates/ready-mixed concrete businesses and related synergies. At the same time, we are mindful of

the risk that U.S. tariffs on exports from Indonesia, Vietnam, and South Korea under the U.S. Trump administration could weigh on markets; in the Philippines, this may invite cheaper Vietnamese products and worsen conditions. That said, cement production at the new line in the Philippines, which began operation in 2024 after some delays, is now on track, and manufacturing costs are expected to decline.

Progress on the 26 Medium-Term Management Plan and Probability of Achievement

Progress of the Medium-Term Management Plan

We view the first year (FY2025) as a solid start. Operating profit for FY2026, the second year of the plan, is projected at

¥85.0 billion, representing a shortfall of ¥15.0 billion from the FY2027 guideline of ¥100.0 billion. To achieve the ¥100.0 billion target, we aim to benefit fully in the next fiscal year from the realization of appropriate domestic cement prices (equivalent to a price increase of ¥2,000/tonne), together with the full-scale launch of blended cement exports, by the final year of the plan.

Financial Strategy to Enhance Corporate Value

To enhance corporate value we will focus on improving ROE, primarily through increasing our operating profit margin. While we recognize that reducing capital through share buybacks

and dividends can also be effective in improving ROE, we believe it is important to maintain financial soundness, using a net D/E ratio of 0.5 as our benchmark. For a capital-intensive equipment-based industry such as ours, it is extremely important to maintain a sound financial structure in order

to secure flexibility in financing, including the issuance of corporate bonds. Accordingly, we believe that ROE should be improved by increasing profits while also increasing capital—namely, by enhancing the operating profit margin. To this end, we intend to maintain a high operating rate at our domestic cement plants and continue to pursue appropriate pricing.

Toward a PBR Above 1x

Although ROE for the fiscal year ending March 2025 improved significantly to 9.5%, the price-to-book ratio (PBR) remained around 0.6 as of July 2025. One possible reason behind this is a higher-than-expected increase in the cost of capital. Contributing factors may include the fact that cement manufacturing is a “hard-to-abate” industry, one in which CO2 emissions are difficult to reduce, as well as a valuation discount stemming from structural characteristics of the industry, such as declining domestic demand for cement. Given the structure of our business, we recognize the importance of clearly conveying through our IR activities that profitability and growth potential in our overseas operations serve as major drivers

of our corporate value. On the other hand, further initiatives are needed to improve the operating profit margin. As part of our global strategy, we are promoting the export of blended cement, which uses less clinker. This initiative is aimed at capturing strong overseas demand. Establishing a structure to generate earnings through the export of blended cement will also help raise the operating rate of our domestic plants, making it one of the key strategies for enhancing profitability and moving closer to achieving a PBR above 1.0.

Financial strategy to support enhanced profitability

To enhance profitability we position the improvement of the operating profit margin and ROE as our top priorities. However, as we pursue human capital–focused management, personnel expenses are expected to continue rising, leading to higher fixed costs. Accordingly, it is essential to build an effective and efficient organizational structure and workforce allocation that ensure such investments in people contribute to the enhancement of corporate value. From the perspective of profit management, we see room to consider integrating administrative and sales functions across business segments and reallocating human resources to our overseas operations, which represent a growth area. In addition, to reduce financing costs across the Group, we are shifting the funding sources of Group companies from external institutions to our financial

subsidiary, Taiheiyo Accounting & Financial Services Corporation (TAF). Specifically, through the Cash Management System (CMS), approximately 80% of the loans extended from TAF to Group companies are funded by surplus cash within the Group. In addition, we launched an accounting service business this fiscal year to handle accounting operations for Group companies.

Going forward, we aim to enhance productivity by promoting greater operational efficiency across the Group.

Financial strategy for pursuing growth

In FY2025, as part of our growth strategy investments, we acquired assets for the aggregates and ready-mixed concrete businesses in the United States and carried out a plant renewal project in the Philippines. Our investments in the United States are aimed at expanding our stable and highly profitable aggregates business, and further strengthening our foundation through vertical integration, such as reinforcing the supply chain. With strong demand expected to continue alongside population and economic growth in the U.S., we anticipate steady returns on these investments. Investments in the Philippines and Indonesia are expected to have a somewhat longer medium- to long-term payback period compared with those in the United States, partly due to the

impact of current U.S. tariffs. Meanwhile, with respect to carbon-neutral technology development, we are currently advancing investments mainly through national projects, utilizing government subsidies. In the practical application stage going forward, we plan to make proactive capital investments while engaging with other industries and countries.

In managing the effectiveness of these investments, we will continue to place importance on return on invested capital (ROIC) as a key management guideline. A distinctive feature

of our business model is that our domestic cement, resources, and environmental businesses are interconnected along the supply chain and operate in an integrated manner. Accordingly, it is appropriate to view them collectively in ROIC management. Looking ahead, one possible approach is to manage our business portfolio using ROIC indicators across three categories: domestic cement-related businesses (including resources and environmental operations), global businesses, and others (non-cement-related operations).

Reducing the cost of capital

To reduce the cost of capital we first aim to uphold strict financial discipline as a company trusted by investors.

Specifically, we will manage our finances with a focus on maintaining a net D/E ratio of around 0.5. Enhancing our corporate recognition is also an important factor in lowering the cost of capital. Although our Group operates primarily in B2B businesses, we recognize the need to strengthen engagement with individual stakeholders, including consumers who use products made with cement and our employees. Furthermore, to improve our undervalued stock price, it is essential to communicate our business model accurately and work to raise market evaluations, particularly for our domestic operations.

Shareholder return policy

Under the 26 Medium-Term Management Plan, we aim for a total shareholder return ratio of 33% or higher over the three-year period. As for dividends, we increased the annual dividend for FY2025 to ¥80 per share, including an interim dividend of ¥40, and plan to raise it further to ¥100 per share for FY2026, including an interim dividend of ¥50. In addition, we will actively repurchase our own shares while timing our growth investments appropriately, with the goal of enhancing shareholder value. While maintaining a balance between growth investment and shareholder returns, we are also

working to strengthen our financial base to support sustainable growth.

In conclusion — Message from the Executive Officer responsible for Finance

To enhance corporate value, it is essential to strengthen all forms of capital—manufacturing, financial, and human. To make timely and appropriate investments in each, we will maintain a sound financial foundation and a framework that enables agile financing. By advancing full-scale ROIC-based management to improve performance transparency and by enhancing capital efficiency, we aim to achieve our Medium-Term Management Plan while keeping an ROE level above 10% in sight.

Manufacturing Capital

26 Medium-Term Management Plan — Initiatives for Enhancing Corporate Value and Strengthening Capital Issue Initiative:

Amid the aging of many facilities that have been in operation for over half a century, we are working to strengthen equipment resilience to establish a stable production and supply system, while also advancing equipment upgrades that incorporate functional

improvements leading to energy savings and cost reductions. In addition, we are promoting factory automation through smart factory initiatives, including autonomous drone patrols of the plants and the development of AI-based equipment

management systems.

Accelerating the shift to blended cement

To shift to a production system suitable for the stable supply of blended cement, which is in high demand overseas. The company has decided to construct new manufacturing and shipping facilities for blended cement using classified fly ash at the Saiki Ash Center, positioning it as an export hub for fly ash–blended cement to Southeast Asia.

Maximizing Waste Processing Capacity

Competition for waste collection has intensified with both industry peers and other sectors. To enhance the ability to process waste that is difficult for other industries to accept, the company is installing sewage sludge co-processing facilities at the Kumagaya Plant and the Fujiwara Plant.

Elimination of Industrial Accidents

With the goal of eradicating industrial accidents—including those within the supply chain—and ensuring a safe working environment, the company is systematically implementing safety, security, and hygiene initiatives across the Group. Each business site is promoting:

  • Enhancement of safety management systems /Reform of safety awareness /Awareness of relevant laws and regulations /Instruction on safety rules /Implementation of 4S and secure walkways /Visualization of hazardous areas /Safety improvements of equipment

To ensure that lessons learned from past accidents are not forgotten and that safety rules are strictly observed, the company also posts on-site incident information at accident locations.

Reinforcement of Plant Facilities

In addition to renewing aging equipment, the company is implementing functional improvements aimed at energy conservation and cost reduction. The waste heat power generation and in-house power generation facilities at various plants have become outdated; therefore, the Kumagaya and Saitama plants have completed their transition to gas power generation systems, while construction is currently underway at the Fujiwara Plant.

Knowledge and Skills Transfer

Experienced elder employees re-hired after retirement are passing on their expertise and know-how, while core maintenance technologies are being handed down through initiatives such as the

“Maintenance Dojo” launched at the Kumagaya Plant. Under the “Overseas Trainee Program” employees are dispatched for short-term assignments to overseas plants, not only to acquire technical skills but also to foster personal growth through interaction with local staff.

In quality assurance, we will continue to operate our existing quality management systems while applying the technologies we have cultivated since our founding to ensure that our customers are fully satisfied with the quality of our products. This commitment extends to our new initiatives in promoting the production and shipment of blended cement and low-carbon blended cement.

Intellectual Capital

In April 2025, the Company established the Research & Development Division by integrating the former Central

Research Institute and the Intellectual Property Department, in order to support the “3D Approach for a Sustainable Future” set forth in the “26 Medium-Term Management Plan” from a technological perspective. The new Division comprises three organizations — the Cement & Concrete Research Laboratory, the New Technology Research Laboratory, and the Research

& Development Department — thereby building a cross-

functional R&D structure that includes intellectual property. This enables the enhancement of technological innovation and the efficiency of intellectual property activities across the Group. The Division also collaborates with the GX Department and the C2SP Kiln Project Team, both established at the same time, to develop innovative technologies for achieving carbon neutrality. Through these efforts, the Division aims to fulfill its role as a comprehensive research institute that contributes to the Group’s business expansion and improved profitability.

To meet the growing overseas demand for blended cement and supplementary cementitious materials, our Group is developing new blended cement products that utilize locally available resources. In particular, in the U.S. market where demand remains strong, we have enhanced our presence by developing and marketing limestone blended cement.

Further Promotion of Global Strategies

In addition, we are promoting the development of a “ternary blended cement” (containing 7% limestone and 11% natural pozzolan), which allows for a higher proportion of supplementary materials and offers improved profitability and durability compared with conventional limestone blended cement (containing 11% limestone). We have recently established a manufacturing formulation that addresses practical challenges such as flowability during placement and cracking during construction.

Revitalization of Domestic Business

As domestic demand for cement continues to decline, we are actively promoting technological development aimed at exporting fly ash blended cement to the fast-growing markets of Southeast Asia, while maintaining the production capacity of our domestic plants in order to continue to play their role as waste and by-product processing facilities. As part of this effort, we established a production formula for Taiheiyo Cement Philippines, Inc. that achieves both profitability and low carbon emissions through maximum utilization of fly ash, leading to the successful shipment of 10,000 tonnes in February

2025. Looking ahead, with a view to further expanding our market presence in Southeast Asia, we will continue to develop formulations and products that comply with the standards and specifications of each country, and will enhance our competitiveness in the global market.

Promotion of Sustainability Management and Contribution to Carbon Neutrality

To help realize a sustainable society, we are advancing technological development that contributes to solving social challenges such as achieving carbon neutrality and addressing labor shortages. In

Social Environment pursuit of carbon neutrality, the cement industry as a whole is working to revise the JIS standards to

The business environment surrounding our Group is undergoing a major transformation due to structural changes in society, diversification of market needs, and the accelerating pace of technological innovation. While such rapid changes present unpredictable risks, they also create opportunities

to explore new possibilities in research and development. Our Company embraces these changes with a positive outlook and continues to advance initiatives aimed at future-oriented value creation.

  • Decline in domestic demand for cement

    Risks

  • Response to carbon neutrality

  • Labor shortages in the concrete and construction industries, and advancing deterioration of infrastructure

    Opportunities

  • Further utilization of R&D capabilities cultivated over many years to expand the blended cement business in overseas markets

  • Growing demand for productivity improvement and labor-saving measures in cement and concrete manufacturing, as well as in construction and maintenance management

    raise the upper limit of minor additional components in ordinary Portland cement from 5% to 10%. Currently, we are in discussions with relevant authorities to simplify various approval and certification procedures in order to reduce the burden on users after the revision.

    To address labor shortages, we are promoting the development of DX technologies that contribute to labor-saving across the entire process — from cement and concrete manufacturing to construction and maintenance of infrastructure structures. As part of these efforts, our “PreSLump AI” technology, a concrete slump prediction system that supports quality control at ready-mixed concrete plants,

    has secured 14 contracts since its launch in April 2023, contributing to labor-saving at ready-mixed concrete and precast product plants.

Human Capital [Feature] Labor Unions

The Taiheiyo Cement Labor Union is a labor union established in March 2002 through the organizational integration of the Nihon Cement Labor Union, the Zen-se Onoda Cement Labor Union, and the Chichibu Onoda Labor Union, and it consists solely of employees of Taiheiyo Cement. Since its establishment, its mission has been to achieve happiness and improved social status of working people, to protect the employment and treatment of its members, and to support the lives of its members and their families, and it carries out various initiatives while maintaining close communication with Taiheiyo Cement.

Initiatives

Based on mutual trust and mutual understanding "Labor-Management Councils" and "Labor-Management Briefings" are held as needed as a forum for consultation and exchange of opinions between labor and management. The aim is to develop constructive discussions, with the company and the union communicating with each other, on a wide range of topics starting with the spring

negotiations, and including revisions to systems and regulations affecting union members. In addition, five "Central Labor-Management Specialized Committees" have been established, and an active exchange of opinions is conducted on topics such as the remuneration system, employment formats, working hours, workplace diversity, and Health and Productivity Management (H&PM). In addition,

in January 2025, a dialogue was held with Taiheiyo Cement's President Taura regarding the situation surrounding the company and initiatives of the 26 Medium-Term Management Plan aimed at realizing "Our future vision and direction" and the details were published in the union's official newspaper.

A word from Chairman Asami

Our top priority is "ensuring a workplace where everyone can work safely and healthily."

We aim to foster a workplace environment where everyone "arrives at work healthy and smiling, and goes home healthy and smiling" while continuing to maintain open organizational management.

The economic and social environment surrounding us is changing rapidly, and there are many diversifying and complex issues, but we have continued to maintain open organizational management by holding thorough and frank discussions with union members and connecting with each and every individual. In particular, we are actively communicating with the younger generation, whose numbers have been increasing in recent years, and are also focusing on developing human resources who will lead the next generation.

FY2026 Union Headquarters Executives

In addition, based on the spirit of "mutual help and support", which is the mission of the labor union, and the basic principles set forth in our vision, we are actively

working to realize a society where union members can lead meaningful daily lives with peace of mind while balancing their work and private lives, based on the labor-management relationship of "mutual trust and mutual understanding" built by our predecessors. We are confident that employees who can work with vitality will also contribute to the company's performance by increasing their motivation and improving their competencies (the behavioral characteristics of high performers). This spring, the company agreed to raise wages,

including a starting salary of ¥300,000 for university graduates (non-area specific positions). We are grateful for the company's understanding and efforts in this regard. And the top priority

Environmental Management

Based on our environmental management policy, we comply with environmental laws and regulations and engage in business activities that consider the environment. Each plant maintains emergency response plans in preparation for possible environmental accidents. They also conduct periodic fire-fighting drills in cooperation with local fire departments. Other training includes how to reduce environmental impact when an environmental accident occurs, and how to report it to local governments. In addition, as we increasingly utilize ever more diverse forms of waste and by-products, the number of environmental issues we need to consider also increases. We are implementing various environmental measures and striving to reduce our environmental impact.

Environmental Management System (EMS)

Reducing Environmental Impact

Circular Economies

We are promoting the recycling of waste and by-products into alternative raw materials and fuels for cement. This promotes the formation of circular economies from the perspective of suppressing the depletion of natural resources, and also contributes to extending the life of final disposal sites.

Circular Economies

Climate Change (Preventing Global Warming)

A significant amount of CO2 is emitted during the cement manufacturing process. While it is possible to reduce energy-derived CO2 emissions to zero by switching to clean energy, there is a major challenge in that CO2 emissions from raw materials cannot be reduced to zero as long as limestone is used. To contribute to the prevention of global warming and achieve sustainable growth, we have set forth our "Carbon Neutral Strategy 2050" which includes 2030 interim targets, and are promoting CO2 emission reduction measures from a medium- to long-term perspective.

Respect for Human Rights Stakeholder Engagement

In order to practice business activities in which respect for human rights is regarded as the most important challenge for the entire supply chain, we promote human rights awareness activities for the entire group.

In May 2022, we signed the United Nations Global

Human Rights Due Diligence

We recognize that respect for human rights not only means not being complicit in human rights abuses ourselves, but also taking responsibility for preventing and mitigating negative impacts on our suppliers. In addition, we believe that respect for human rights is our responsibility as a global company and is essential for our business activities.

In FY2024, we conducted our first human rights due diligence, focusing on suppliers related to the cement

Compact and endorsed its ten principles relating to human rights protection, the elimination of unfair labor

practices, environmental protection, and the prevention of corruption, and we are engaged in various initiatives to realize these principles.

manufacturing business, which is the core of our business.

We plan to design the system for the second human rights due diligence in FY2025 and implement it in FY2026. We aim to enhance our corporate value by expanding the scope of our investigations, conducting them regularly,

identifying potential human rights risks in the Taiheiyo Cement Group, and taking appropriate measures to prevent or mitigate them in advance.

We are promoting timely and appropriate information disclosure and communication with our stakeholders based on our belief that in order to remain a sustainable company, it is essential for us to fulfill our social responsibility and continue to build good relationships in response to the expectations

and demands of our diverse stakeholders. We will continue to strive to further incorporate the opinions and requests received from stakeholders into our management, and further promote human capital management so that employees, the greatest asset to our company, can work with vitality.

Corrective measures for key challenges in FY2024 and progress in FY2025

Formulation of the Taiheiyo Cement Group Human Rights Policy

Based on the "Mission of the Taiheiyo Cement Group" and

"Business Principles", the Group formulated the "Taiheiyo Cement Group Human Rights Policy" in March 2025. Based on this policy, we will promote human rights initiatives throughout the Group.

Access to legal remedies

Regarding the Whistleblower Program, which previously covered our company and domestic group companies,

we began considering the introduction of a system for overseas group companies in FY2025, and in April 2025, we formulated the "Taiheiyo Cement Group Global Whistleblower Regulations." The overseas group companies covered are proceeding with the formulation of individual company regulations and the establishment of contact points linked to these regulations, and the rollout to overseas group companies is scheduled to be completed within FY2026.

Harassment and abuse

In FY2025, the total number of reports to the internal harassment hotline was 17, which is an increasing trend compared to previous fiscal years. The Human Rights Awareness Promotion Office is strengthening its awareness activities to further disseminate internal regulations on harassment and to prevent it.

Occupational health and safety

P.66

In FY2025, there were 128 occupational accidents, including 4 fatalities, and the absence rate was 0.701% due to an increase in mental illness, failing to meet the target. We will revitalize communication with our sites more than ever before and all employees will align their activities toward safety, security and health.

Bribery and corruption prevention

The Taiheiyo Cement Group positions compliance as the foundation of its business activities, and formulated the "Anti-Bribery Policy" in 2017 and the "Taiheiyo Cement Group Basic Anti-Bribery and Corruption Regulations" in June

2024, and is working to strengthen compliance throughout the Group.

Thorough procurement practices (supplier management)

In March 2025, we formulated the Group's "Procurement

Policy" and "Supplier Code of Conduct" to promote responsible actions, including respect for human rights,

throughout the supply chain. We plan to develop awareness activities for suppliers in the future.

Future Issues

  • Implementation of human rights due diligence (major domestic group companies (other than cement manufacturing) / major domestic primary suppliers (other than those surveyed in FY2024)

  • Implementation of a supplier questionnaire to confirm compliance with the "Taiheiyo Cement Group Supplier Code of Conduct"

[Feature] Employee Engagement "Discussion with the Executives"

Since April 2025, we have been holding a series of events called "Discussion with the Executives," in which executives of managing director level and above visit business sites throughout the country to talk directly with employees.

The objectives are to align employee efforts and motivation by directly conveying the thoughts of management to enhance the driving force of our business strategy, and to have employees get to know the personalities of the managers they rarely meet, in addition to explaining management strategies, so that they feel a sense of affinity

for the managers and, by extension, the company. On the other hand, it is also a valuable opportunity for managers to confirm the actual situation at the forefront of manufacturing and sales. This year's "Discussion" is being held at each business site in three parts: a lecture, a Q&A session, and a social gathering.

The following is a description of the "Discussion" events, including other occasions when management visited business sites and interacted with employees.

Chairman Fushihara in the Chugoku Branch

In September 2025, a discussion with Chairman Fushihara was held at the Chugoku Branch in Hiroshima City. Drawing on his own on-site experience, the Chairman explained the importance maintaining prices, the

importance of understanding operations from a site-oriented perspective through diverse experience, policy trends related to greenhouse gases and related investments, and technological developments, citing specific examples such as the response to the earthquake disaster and circular agriculture in Fukushima. He then answered questions such as "What is the secret to becoming chairman?", "How do you overcome a major failure?" and "What is your advice to young people?" A social gathering followed, where employees, including those from nearby affiliated companies, had frank conversations and deepened their relationships. Chairman Fushihara took this opportunity to visit our group- related facilities in Kitakyushu and Yamaguchi Prefecture.

President Taura in the Kansai Shikoku Branch

In July 2025, President Taura and Senior Executive Officer Kira visited the Osaka office of the Kansai Shikoku Branch to explain the company's policies to employees. President Taura spoke about the progress of the Medium-Term Management Plan and future goals, the theoretical background and mindset for price optimization, trends in the global cement industry, and public trends related to greenhouse gases. In the subsequent Q&A session he answered questions such as "How do you make your work enjoyable?", "What should you do in your 20s?" and "What was the most difficult experience you have had in the past?" Employees working at the Takamatsu office of the same branch also participated remotely.

Senior Executive Officer Matsui in the Tosa Office

In July 2025, Senior Executive Officer Matsui visited the Tosa Office and deepened his interaction with the employees. In his lecture he introduced himself, talked about his work history including his assignment in Vietnam and his involvement with the Tosa Office, his current responsibilities, workplace safety and, finally, the company's performance. In the Q&A session, he answered questions about the circumstances that led to his assignment to Vietnam and the differences between working overseas and working in Japan. Afterward, a social gathering was held, where he interacted and deepened exchanges with employees, including those from nearby affiliated companies. Senior Executive Officer Matsui also energetically inspected nearby affiliated company facilities.

Senior Executive Officer Matsui in the Tokyo Branch

In August 2025, Senior Executive Officer Matsui visited the Tokyo Branch and spoke with employees. In his lecture, he introduced himself, his career history, and the departments he has been in charge of since becoming an executive, and then spoke about company’s current situation, the national cement market, the performance and future prospects of the overseas division, and strategies regarding secondary cementitious materials. In the Q&A session he answered questions such as "How are executives using IT?" and "How can we prevent employees from leaving the workplace?". He continued to interact with employees at the social gathering that followed.

Managing Executive Officer Ban in the Tohoku Branch

In July 2025, Managing Executive Officer Ban visited the Tohoku Branch in Sendai City and spoke with employees. He gave many anecdotes about what he had learned in various departments at the head office, branches, and the ready-mixed concrete company where he was seconded. He then spoke frankly about the company's future challenges and the direction it should take. During the Q&A session, questions were asked about matters such as " industry reorganization", "future hiring policies", "overseas accounting standards" and "criteria for investment decisions". Finally, a social gathering was held, where he was able to deepen his interaction with branch employees.

Managing Executive Officer Takano in the Ofunato Plant

Managing Executive Officer Takano took the stage at a talk session held at the Ofunato Plant in July 2025. After introducing himself, his career history and his involvement with the Ofunato Plant, he spoke forcefully about the R&D department he is in charge of, explaining its structure, key implementation items and human resource development policy, as well as the importance of cooperation with the plant, and the future direction of research regarding plant operations. This was followed by a lively Q&A session with questions such as "What tips do

you have for getting cooperation within the company?", "How to become a reliable employee?" and "How to collaborate with people who have no experience at a plant?". After the session, a social gathering was held to deepen interaction with the plant's employees.

President Taura in the Kamiiso Plant

In August 2025, President Taura and Managing Executive Officer Kawabe visited the Kamiiso Plant to explain the company's policies. President Taura spoke to the employees about the future of the cement industry, the importance of safety, future cement demand forecasts for Japan, the company's mission in responding to severe disasters, the importance of DX (digital transformation), and our company's initiatives and their significance towards GX (green transformation). President Taura illustrated his talk with memorable anecdotes such as the relationship between Hokkaido, where the plant is located, and cement and concrete, and his interactions with famous people. He then answered questions such as "What are the measures to prevent the turnover of young employees?", "What are your thoughts on business diversification?" "the current status of DX?" "What is our public relations strategy?" and "What knowledge should new employees acquire?"

Vice President Asakura in the Research and Development Division

In June 2025, in order to revive the "Discussion with the Executives" at regional business sites for the first time since the COVID-19 pandemic, Vice President Asakura took the lead in visiting the Research and Development Division in Sakura City to engage in dialogue with employees. In his first lectur, he spoke about his own work history, describing the conditions at each workplace and what he learned there, and also about the type of research work he would like to see in the research and development department. During the Q&A session he answered questions such as "What kind of person and skills do you want in an employee?", "What skills are suitable for young employees to progress?", "What is necessary for Japanese people to be successful overseas?" and "What are your thoughts on PR for the company's initiatives?" A social gathering was then held in the cafeteria, where Vice President Asakura interacted with many employees as he visited each table.

Managing Executive Officer Hirata in the Kanto Branch

In August 2025, Managing Executive Officer Hirata's "Discussion" was held at the Kanto Branch in Takasaki City. After humorously sharing his career history since joining the company, including his time at the quarry and at Chinese subsidiaries, he spoke enthusiastically in plain language about new topics that the employees at the Kanto Branch (who specialize in cement sales) rarely come across, focusing on the quarry and mineral resources business division that he is in charge of, such as the investment strategy for quarries and the sales strategy of the Mineral Resources Business Department. In the Q&A session, he answered questions on topics such as "the future vision of the sales system", "quarrying at overseas subsidiaries" ," maintaining quarry safety" and "multi-skill development" He also deepened his interaction with employees at the social gathering that followed.

Managing Executive Officer Murakami in the Kumagaya Plant

In July 2025, Managing Executive Officer Murakami held a discussion session at the Kumagaya Plant. He spoke in a lighthearted manner, starting with his own background and his career and experience at the company, the company's performance, the efforts of the Environmental Business Department he is in charge of, and the role of the Kumagaya Plant, while conveying the management’s thinking. During the Q&A session, he answered questions on matters such as "communication with foreigners", "transfers", "the difficulty of price revisions" and "the vision that employees should share". The employees unanimously commented that they were impressed by the phrase "seeing the same picture" which illustrates the importance of unity of purpose. On the same day, President Taura also accompanied him and gave a similar lecture and Q&A session.

More than 10 "Discussion with the Executives" sessions are being prepared for September 2025 and beyond.
