1. Overview of Business Results

   1. Summary of Business Results

      During the consolidated fiscal year under review, the global economy showed mixed trends. In the United States, although signs of a slowdown emerged in employment conditions and personal consumption, the economy remained resilient, driven by robust capital investment in AI-related fields. In Europe, weak demand persisted, particularly in manufacturing. In China, the recovery in personal consumption lacked momentum, and economic conditions softened. In addition to shifts in U.S. trade policy, worsening tensions in the Middle East drove crude oil prices higher in the second half of the fiscal year. This led to rising fuel and raw material prices, supply concerns, and volatile foreign exchange rates, keeping the outlook uncertain.

      In the electronic components market relevant to the Group, semiconductors and data centers performed strongly, supported by vigorous AI-related investment. The industrial equipment market moved toward recovery as inventory adjustments progressed. By contrast, the automotive market remained sluggish, weighed down by weak demand and heightened uncertainty over tariff issues.

      Under these circumstances, we formulated the Yamaichi Electronics Group's Fourth Medium-Term Management Plan, a three-year plan with FY2023 as the first year (covering the fiscal years ending March 31, 2024 through March 31, 2026). Through this plan, we aim to grow into a company that provides high-quality products and services and achieves a high level of customer satisfaction. We have been working toward this goal by collaborating closely with customers worldwide to develop products that drive future value creation. As part of our strategy, we advanced both growth initiatives and structural reforms to better meet customer needs, while strengthening our financial base and laying the groundwork for future growth. Based on this Medium-Term Management Plan and anticipating growing global semiconductor demand, we have continued to invest in expanding production capacity to strengthen our stable supply system for semiconductor sockets and to respond quickly and efficiently to diversifying demand for connectors used in telecommunications, automotive, and industrial equipment. At the same time, we have continued initiatives to reduce costs through further improvements in productivity and quality.

      As a result, consolidated results for the fiscal year under review were net sales of 52,698 million yen (an increase of 16.3% year on year), operating profit of 11,556 million yen (an increase of 40.5% year on year), ordinary profit of 12,126 million yen (an increase of 57.7% year on year), and profit attributable to owners of parent of 9,073 million yen (an increase of 73.1% year on year). Under the Yamaichi Electronics Group's Fourth Medium-Term Management Plan, one of our targets for the final year, the fiscal year ending March 31, 2026, was to exceed 50.0 billion yen in net sales and 10.0 billion yen in operating profit, and we achieved this target.

      Our business performance on a segment-by-segment basis is shown below.

      [Test Solutions Business]

      In test sockets, sales of products used in our core markets, including smartphones, PCs, automotive devices, and wearables, remained strong. In burn-in sockets, sales and profit were affected by delays in customer capital investment, particularly in automotive logic semiconductors. By contrast, sales of

      memory semiconductor products showed a recovery trend in the second half as investment resumed. Across the segment as a whole, profit was also affected by rising prices for gold, copper, and other raw materials.

      As a result, net sales amounted to 26,424 million yen (an increase of 5.2% year on year), and operating profit amounted to 7,009 million yen (a decrease of 1.4% year on year).

      [Connector Solutions Business]

      In telecommunications equipment, sales were strong, supported by steady demand for core network equipment and a substantial increase in data center demand, including AI-related applications. In industrial equipment, sales recovered gradually as inventory adjustments among major European customers bottomed out. In automotive applications, performance was sluggish due to weak global demand and a slowdown in the EV market. Although the segment was affected by rising prices for gold, copper, and other raw materials, both net sales and operating profit reached record highs for the Connector Solutions Business.

      As a result, net sales amounted to 24,742 million yen (an increase of 30.6% year on year), and operating profit amounted to 4,406 million yen (an increase of 263.2% year on year).

      [Optical-related Business]

      Amid an overall recovery in orders, sales of communications-market products remained solid, and improvements in productivity and quality contributed to significant gains in performance.

      As a result, net sales amounted to 1,531 million yen (an increase of 23.9% year on year), and operating profit amounted to 206 million yen (compared with an operating loss of 25 million yen in the previous fiscal year).

   2. Overview of Financial Position for the Fiscal Year (Assets)

      Current assets at the end of this consolidated fiscal year amounted to 40,489 million yen, an increase of 8,376 million yen from the end of the previous consolidated fiscal year. This was mainly due to increases of 4,809 million yen in cash and deposits, 2,230 million yen in trade receivables, and 2,321 million yen in inventories such as merchandise and finished goods, which more than offset a decrease of 1,940 million yen in deposits included in other current assets related to the acquisition of treasury shares. Noncurrent assets totaled 22,763 million yen, an increase of 1,486 million yen from the end of the previous consolidated fiscal year. This was mainly attributable to a 375 million yen increase in right-of-use assets due to lease agreements for the headquarters building of our consolidated subsidiary, Yamaichi Electronics U.S.A., Inc., and a 622 million yen increase in software in progress related to the development of our next core system.

      As a result, our total assets amounted to 63,253 million yen, an increase of 9,863 million yen from the end of the previous consolidated fiscal year.

      (Liabilities)

      Current liabilities at the end of this consolidated fiscal year amounted to 13,260 million yen, an increase of 2,817 million yen from the end of the previous consolidated fiscal year. This was mainly due to increases of 1,290 million yen in notes and accounts payable-trade and 700 million yen in provision for bonuses. Noncurrent liabilities totaled 3,286 million yen, an increase of 16 million yen from the end of the previous consolidated fiscal year.

      As a result, total liabilities amounted to 16,546 million yen, an increase of 2,833 million yen from the end of the previous consolidated fiscal year.

      (Net Assets)

      Net assets at the end of this consolidated fiscal year amounted to 46,706 million yen, an increase of 7,029 million yen from the end of the previous consolidated fiscal year. This was mainly due to profit attributable to owners of parent of 9,073 million yen and an increase of 1,323 million yen in foreign currency translation adjustment, which more than offset dividends of surplus of 1,691 million yen and the purchase of treasury shares of 1,907 million yen.

      As a result, the equity ratio was 73.6% (74.0% at the end of the previous consolidated fiscal year).

   3. Overview of Cash Flows for the Fiscal Year

      Cash and cash equivalents (hereinafter referred to as "funds") increased by 4,443 million yen from the end of the previous consolidated fiscal year to 17,237 million yen at the end of the consolidated fiscal year.

      The status of each cash flow and its factors during the consolidated fiscal year are explained below.

      (Cash flows from operating activities)

      The funds obtained from operating activities amounted to 10,053 million yen (an increase of 11.6% year on year). This was mainly due to profit before income taxes of 12,014 million yen.

      (Cash flows from investing activities)

      The funds used in investing activities amounted to 3,469 million yen (a decrease of 5.1% year on year). This was mainly due to payments of 2,588 million yen for the purchase of property, plant, and equipment.

      (Cash flows from financing activities)

      The funds used in financing activities amounted to 2,736 million yen (a decrease of 50.2% year on year). This was mainly due to dividends paid of 1,689 million yen.

   4. Future Prospect

   The global economy in the fiscal year ending March 31, 2027 is expected to remain uncertain due to heightened geopolitical risks stemming from worsening tensions in the Middle East and trade policies in various countries.

   In the markets surrounding the Group, the semiconductor and electronic components markets are expected to expand over the medium to long term, driven by demand for AI and data centers. Under

   these circumstances, we formulated the Yamaichi Electronics Group's Fifth Medium-Term Management Plan, a three-year plan with fiscal year 2026 as the first year (covering the fiscal years ending March 31, 2027 through March 31, 2029).

   Under this Medium-Term Management Plan, we have set key priorities by backcasting from five- and ten-year perspectives and aim to achieve sustained growth. We will address management issues from a medium- to long-term perspective, strengthen our growth foundation from both business and organizational perspectives, and enhance non-financial value through initiatives such as enriching human capital, advancing sustainability activities, and strengthening governance. At the same time, by steadily executing growth investments and improving capital efficiency, we aim to enhance corporate value from both financial and non-financial perspectives and achieve sustainable growth.

   For the fiscal year ending March 31, 2027, we forecast consolidated net sales of 60,000 million yen (an increase of 13.9% year on year), operating profit of 13,000 million yen (an increase of 12.5% year on year), ordinary profit of 12,800 million yen (an increase of 5.6% year on year), and profit attributable to owners of parent of 9,200 million yen (an increase of 1.4% year on year.

   We plan to increase both revenue and profit for the Group as a whole. This full-year earnings forecast is based on information and projections available to the Group as of the date of this disclosure. While there are concerns over rising crude oil and raw material prices and supply chain disruptions due to the recent worsening of tensions in the Middle East, these effects have not been factored into the forecast because it is currently difficult to estimate their impact with reasonable accuracy. We will promptly disclose any expected impact on our business performance. The exchange rates assumed in the forecast are 150.00 yen to the U.S. dollar and 175.00 yen to the euro.

2. Basic Concept of the Selection of Accounting Standards

Considering the comparability of consolidated financial statements over time and across companies, the Group intends, for the time being, to prepare its consolidated financial statements in accordance with Japanese Generally Accepted Accounting Principles (J-GAAP).

In the future, we will continue to consider adopting International Financial Reporting Standards (IFRS), taking into account trends in IFRS adoption among domestic peers.
