Becoming a solution creator that flexibly finds optimal solutions to changing conditions

We are now living in a "society with no correct answers." And the business environment surrounding Hioki is changing dramat- ically. In addition to addressing climate change and rising energy prices, we must accelerate our efforts to realize a decarbonized society. When I visit countries outside Japan, I am struck by the speed of change in the external environment and the speed with which those countries are responding. This gives me a sense of urgency that Japan is lagging behind.

Becoming a front-runner in the electrical measurement instruments industry by placing "people" as the source of our growth

Hioki contributes to society as a manufacturer of electrical

measuring instruments. These are considered the essential tools

Presidentof industry that support the R&D efforts and production lines of our corporate customers. Going forward, we must address changing conditions, which are becoming more complex, and develop growth strategies based on short-,medium-, and long- term perspectives. From a global perspective, varied national policies on issues such as sustainability necessitate that we implement different measures for each country. We also need to be flexible and swift in developing optimal solutions.

HIOKI Integrated Report 2023

For this, it is important for employees to think, act inde- pendently, and be aware to provide new value to society. With this in mind, I have focused on returning to Hioki's philosophy of "Respect for Humanity" and "Contribution to Society" (see page 3 for details) or, in other words, "philosophy-driven" management. Looking back on the intention behind the philosophy, which was formulated in 1986, I asked our management team at the time, "What things do you wish to value?" We concluded that the core of the philosophy is that "each person should individually think things through."

The source of Hioki's growth is its people, and the slogan of Vision 2023, our long-term management policy announced in 2020, is "Beyond Measure." In addition to the technological perspective, which includes creating new inspection standards, it refers to our belief that all Hioki Group employees should be "solution creators" who go beyond "measurement" to think what kind of value they can provide to customers worldwide.

As many of our customers take on new business challenges, we are receiving more and more inquiries and requests for consultation about ways to solve their problems. To respond quickly, we must mobilize all our Company's capabilities. Internally,

we have reinforced our corporate culture of cooperation and support, where we pool our wisdom across departmental boundaries to solve customer issues. As a result, we now hear many more words of gratitude than before. In this way, Hioki will work as one to focus on problem-solving and building relationships of trust with its customers. We will adhere to this stance rather than blindly sell products or offer discounts, which will also help bolster sales.

Hioki has various systems in place for employees who aspire to become solution creators. Our new HR system, launched in 2018, was designed to allow employees to change their job roles, participate in projects of interest, and attend career and purpose training. We also announced our medium-term key policy, HI-CEO+ (see page 32 for details), which covers the period from 2023 through 2025. This policy calls for "all employees

to seek change, respond to change, and act on change as an opportunity with a sense of ownership (entrepreneurial spirit)." Through its business and following its corporate philosophy, Hioki is helping employees fulfill their individual sense of purpose-that is to say-what they desire to "do, achieve, challenge, and contribute." We are working to create

a system that allows individual employees to challenge themselves with a broader range of choices for self-realization.

Aiming to be an industry front-runner and becoming an indispensable presence for electrical measurement solutions

By balancing the two goals of resolving social issues and achieving sustainable growth, Hioki aims to become a highly profitable company. Our targets are to achieve an operating profit margin of 20%, an overseas sales ratio of 70% or higher, and a return

on equity (ROE) of 10% or higher. Rather than chasing after scale, however, we are committed to delivering value, so we do not consider short-term revenue growth to be our ultimate goal.

In Hioki's Vision 2030, we indicated where we wanted to be in

10 years (Hioki in 10 Years) and how we will contribute to society. In it, we focus on what we can do to: one, solve social issues with customers around the world who are embracing the challenge of decarbonization; and two, challenge ourselves with new endeavors and create new value. We will fulfill these goals by advancing measurement technologies as an industry front-runner. While identifying customers' needs, we will develop new markets where Hioki can contribute. By formulating growth strategies based on these two axes, we aim to become an industry front-runner.

HIOKI Integrated Report 2023

In a world centered on electric energy, Hioki can provide solutions in all fields that use electricity infrastructure, including solar power generation, power distribution, and power con- version. We also invest in key markets with new social systems. In May 2023, for example, we helped plan and organize the ASEAN Battery & Electric Vehicle Technology Conference, held in Indonesia. Various organizations, including a government-led consortium, participated in this conference, representing a next-generation business model. Through our involvement, we aim to spread recognition that "when it comes to battery measurement, you go to Hioki."

As an independent solution creator, Hioki will work to become indispensable in the global market.

Rather than simply selling products, we offer one-of-a-kind value to customers worldwide who are trying to create new technologies. It is also essential to become an indispensable presence that people turn to when they need advice. By doing so, we can join other front-runners at the top of our industry. If we can find a niche that has not yet been established, we can add even greater value. This is one principle of Hioki's growth strategy for the medium and long term and the direction of its business development in new global markets (see page 15 for details).

Achieving speedy decision-making and execution so that we can provide products and services in a timely manner

We see an increase in open innovation and collaboration around the world. Hioki is also promoting collaboration and relationship strengthening with companies outside Japan.

One of these companies is ETAS, a subsidiary of Bosch (the German automotive parts manufacturer), known for its vehicle R&D software. During the COVID-19 pandemic, we had to communicate online, which in overseas marketing ironically enabled us to make swifter product offerings. Hioki has sales subsidiaries and engineers stationed in major overseas countries. All of them take ownership of their work. This allows us to provide products and services when needed, by listening to our local customers' specific requirements on-site. We have also reformed our organizational structure by appointing a new Chief Marketing Officer (CMO) to ensure that overseas markets are correctly explored and decisions are made quickly. Until recently, quite a few of our customer solutions had been passive. Our current desire is for each of us to act more independently and proactively to provide new value, thereby demonstrating Hioki's indispensability and presence.

As I mentioned earlier, Japan is lagging behind in terms of responding to changes in the global external environment. However, the opportunity to turn things around will definitely come. In preparation for that time, we will closely monitor issues from Japan and consider the best ways to address them.

Initiatives to realize Our Vision

Addressing social needs in a wide range of fields

The Integrated Report that was published in 2022 gave us the opportunity to help people understand what we value in our businesses. To make it easier to understand various aspects of our businesses, we have also become more creative in the way we provide information. Instead of just disclosing results, we decided to give clear indications of our future direction.

In the process, we have attracted attention from domestic and foreign investors, business partners, and listed companies. This has resulted in Hioki being featured in an increasing number of national newspapers, specialized magazines, and other media.

chains, and realizing new internal structures. Innovation will be manifested through combinations of new or old elements, and we are making Companywide efforts to make progress in the five innovations.

For example, we established the Creative Collaboration Laboratory in March 2023 to create new customer value. This facility provides an environment for joint research with customers on batteries and power electronics, as well as hydrogen, a next-generation energy source. It serves as a forum for equal conversation about creating solutions. Through it, we can now explore how our customers are creating sustainable social innovations through the processes of development and experimentation. Immediately after the lab's establishment, we succeeded in joint development in the motor field and achieved

• Five innovations:
  Creating new combinations in multiple fields

Creating new customer value

Building new production systems

Building relationships for creative collaboration with customers to forge a new society

Building new supply chains Realizing new internal structures

To build new production systems, we reviewed our existing systems and improved our productivity. In 2021, we started operation of a factory on the site of our partner company in Sakaki, Nagano Prefecture (Sakaki being adjacent to Ueda, where our head office and main factory are located). Then, in 2022, we extended the floor space of our head office factory. These measures have enabled integrated production and improved overall productivity. Meanwhile, to strengthen cooperation with suppliers, we held a face-to-face meeting with them to discuss materials procurement schemes in January 2023, for the first time in three years.

While investors ask us questions about how we are reviewing our business portfolio, we can say our strength lies in our ability to combine electrical measurement solutions in multiple fields.

Rather than subdividing our portfolio along product lines, we believe it is important to combine solutions and create new technologies in response to market needs (see page 14 for details).

For many years, Hioki has developed measurement technologies that sustain numerous world-leading Japanese products. These include high-efficiency motors used in various industries, inverters for air conditioners and other home appliances, and cutting-edge battery and solar panel technologies. We have modified each

of our technologies as a combination of solutions according to market needs. As the global trend toward decarbonization accelerates and electricity becomes our central energy source, we contribute to the advancement of electric vehicles (EVs) through our technologies. Using Hioki's measurement technologies in EVs leads to enhanced motor efficiency, safety, and performance, which in turn contributes to building a circular economy.

More and more companies are seeking to collaborate with Hioki in the high-profile field of battery technologies. In this constantly evolving world, we are closely monitoring industry trends while fine-tuning our technologies to meet market needs.
