Yokogawa Bridge Holdings Corp. (YBHD) was created in August 2007 to integrate theGroupʼs multi-faceted capabilities in a flexible, organic manner.
With our consistently industry-leading Bridge Business playing a central role, we havesuccessfully integrated YBHDʼs multi-faceted capabilities to develop business activities that make a positive contribution to society. We have also been working actively
to develop our Civil Engineering Business (which includes system structures, special-purpose buildings, civil engineering related products, etc.), Precision Equipment
Business, and other new business areas, and have established systems that will provide the foundations for further evolution.
Now is the time when we must reinforce our commitment to society, which our company has maintained for over a century since its founding, and to remind ourselvesof our corporate philosophy of “Contribution to society and the public, and soundmanagement,” so that we can leverage the combined power of the group as a wholeto create infrastructure for society in a way that only YBHD can.
With high-level technological capabilities, an impressive track record of past performance, and multi-talented human resources, ““technology-focused Yokogawa,”
comprising, will continue to undertake activities for the next 100 years aimed at
implementing societal infrastructure that people can use with safety, comfort andpeace of mind.

Contributing to the futureof the world by providing the infrastructure thatsociety needs
The YBHD Group has focused on building societal infrastructure and the foundations that support peopleʼs daily lives through our Bridge Business, whichtargets both new construction and maintenance of existing structures, and our
Civil Engineering Business, which is oriented towards the construction of system
structures for factory and warehouse facilities.
The last few years have seen a rapid acceleration of the supply chain management (SCM) revolution and in the pace of adoption of e-commerce in all sectors.
Recognizing the growing importance of the highway infrastructure that supports
these aspects of logistics, and responding to the rising demand for warehousefacilities, we have made a positive contribution to society by providing safe,
high-quality products.
Going forward, the YBHD Group will work towards the realization of long-term
protection of bridges, multifaceted steel structure engineering and constructionof a robust operational foundation, as well as sustained expansion, and will seek
to achieve further intensification of Group management, creating new businessareas while strengthening the competitiveness of each business, driving the
expansion of our global business activities through the proactive recruitment ofinternational talent. We are also working to identify various types of materiality
from an ESG (Economic, Social and corporate Governance) perspective, andmaking an active effort to address these issues so as to help realize a sustainable
society.
Working from a platform centered on our corporate philosophy of “Contribution
to society and the public, and sound management,” the YBHD Group will contribute to the resolution of a wide range of social problems through the buildingof societal infrastructure and technological innovation.

The YBHD Group undertakes business activities that involve the building of societal infrastructure and the realization of technological innovation, based on our corporate philosophy of “Contribution to society and the public,
and sound management.” The past few years have witnessed dramatic changes in society, with environmental
problems growing steadily more serious.
In response, the YBHD Group utilizes the process outlined below to identify the materiality (i.e. key issues) that weneed to prioritize addressing as a Group, based on an ESG (Economic, Social and corporate Governance) perspective and in line with the United Nations Sustainable Development Goals (SDGs) and the Groupʼs business strategy.
This allows us to work actively to tackle various social problems as we strive to help realize a sustainable society.

The YBHD Groupʼs Materiality(Key Issues)
Materiality Identification Process
1. Selection of materiality candidate items for examination

Corporate philosophy: Contribution to society and the public, and sound management

Taking into account our corporate philosophy, the SDGs, and analysis of investor evaluation items (e.g. FTSE, RobecoSAM, SASB,etc.), we collated the needs of our Companyʼs stakeholders, and then selected candidate items for materiality by holding interviews at
individual Group companies and divisions, and using internal processes to refine and expand the candidate items.
Subsequently, taking into account the social and business environments in which the YBHD Group and our stakeholders operate, as
well as important social trends and the issues that are of concern to our stakeholders, we examined the question of what measures
we will need to take in the future in terms of risks and opportunities, including those relating to corporate value creation, and compiled
a list of materiality items.

ESG

Climate change andnatural disasters
Environmental

2. Prioritizing and weighting of materiality candidate items
The list of materiality candidate items was subjected to internal evaluation from both quantitative and qualitative perspectives, and theadvice of external experts was canvassed. Building on this, we examined the importance and impact of each materiality candidate
item for the YBHD Group and for our stakeholders with regard to medium- to long-term corporate value creation, and assigned apriority order and weighting to each item.

Occupational health andsafetyThe identified materiality
The 18 materiality items that were identified, and the corresponding SDGs, were as outlined below. Going forward, quantitative andqualitative key performance indicators (KPIs) will be set for each item, taking into account the views of external experts. These KPIs
will provide a basis for the implementation of various activities.
The results obtained from these activities will be reviewed by external experts, by members of the Groupʼs Sustainability Committee, andby company employees, with the implementation of a PDCA cycle to achieve ongoing improvement of YBHDʼs business operations.
In the event of any new changes affecting the social environment or other aspects of the external environment, the relevant materiality
items will be adjusted as necessary.

3.Determination of materiality based on deliberation by an intra-group,
cross-departmental body (the Sustainability Committee) and review by members of senior management
An interdepartmental body (the Sustainability Committee) newly established within the Group undertook repeated deliberations on
those items in the materiality matrix that were deemed to be of high importance and high impact, and the list of materiality items wasrevised to generate a final list of candidate items that included governance-related items. Taking into consideration environmental
issues, etc., that have been a focus of recent attention, the candidate items were narrowed down to determine the materiality issues
that the YBHD Group needs to prioritize and target.
A review was then undertaken by senior managers, specifically by members of the Managing Executive Officers Committee, whodetermined a final list of 18 materiality items in 10 sectors.

Our Businesses
Maintenance businessWe are a leading company interms of fulfilling our social mission of safeguarding bridges.

Bridge BusinessIn the Bridge Business, the trend awayfrom new construction towards greater
emphasis on maintenance and retrofittingof existing bridges, or in other words from“flow” towards “stock,” is accelerating. In
recent years, there has been growing concern that much of the infrastructure built
throughout Japan during its era of rapid
economic growth is starting to become
old and decrepit. In response, plans arebeing formulated and implemented to facilitate a large-scale renewal and renovation
program, with a particular focus on urban
expressway bridges, along with large-scale

repair work on the bridges of the Tokaido
Shinkansen high-speed rail line, etc. Thereis also an urgent need for the rapid formulation and implementation of plans toundertake retrofitting and preventive maintenance aimed at extending the lifespanof bridges. The YBHD Group has established a maintenance business framework
to provide a total solution that covers
every stage from inspection and surveys
through to maintenance and reinforcement
work design, materials manufacturing andon-site installation. As a leading company
in the bridge business, YBHD is actively
working to fulfil its social mission of helping
to safeguard bridges.
