Tomio Miyazaki
Fiscal year 2025 was marked by the need to respond to U.S. tariff policies. At the same time, geopolitical risks intensified in various regions around the world, including Ukraine and the Middle East, making the outlook for the global economy increasingly uncertain. The automotive industry also experienced significant changes in its business environment, including a slowing pace of electrification, the rise of Chinese manufacturers, and the emergence of supply chain risks.
Despite these challenges, we achieved net sales of ¥162.3 billion, operating profit of ¥11.2 billion, ordinary profit of ¥12.4 billion, and net income attributable to owners of the parent of ¥8.8 billion in fiscal year 2025, reaching record-high sales and profits for the second consecutive year. In addition, our U.S. operations returned to profitability for the first time in eight years as a result of progress in our production transfer project. We believe these achievements reflect our ability to respond effectively to changes in the business environment, as well as our steady efforts to enhance productivity, strengthen quality
management, and improve overall operational performance as an automotive parts manufacturer.
On April 27, we announced our new medium-term management plan, "T.RAD-2026." As a specialized manufacturer of heat exchangers, we will further advance our multi-pathway strategy to address the diverse needs of all powertrain types. We will focus on expanding sales of our multi-function radiator, for which we have already secured orders, while further strengthening our presence in the automotive parts market. Looking ahead, we also see significant opportunities for heat exchanger technologies beyond the automotive sector. Over the medium to long term, we will pursue growth opportunities in data centers,
humanoid robots, and space-related applications.
In fiscal year 2025, our ROE reached 17.2%, exceeding our initial target of 15%. Under the new medium-term management plan, we will further advance growth investments and capital-efficient management, aiming to achieve net sales of ¥200 billion or more and ROE of 20% or more in fiscal year 2030. With regard to dividends, we have set a target of progressive dividends with a payout ratio of 50% or more and DOE of 5% or more. We will also continue to steadily strengthen shareholder returns.
In 2026, we will celebrate the 90th anniversary of our founding. Under our management philosophy of contributing to the realization of a sustainable society that is friendly to the global environment through the provision of superior thermal energy conversion technologies and services, we will continue to build upon the world-class technologies and expertise we have
cultivated over the years and strive to achieve the next stage of growth.
We respectfully ask for your continued understanding and support.
