1. Qualitative Information on the Quarterly Financial Results

   1. Explanation of Operating Results

      In terms of the domestic business environment during the three months under review, construction investment remained solid against the backdrop of recovery in corporate spending in addition to solid government spending mainly for national resilience strengthening. In our business, we worked to promote the Implant Method*1mainly for disaster recovery and reconstruction projects as well as national resilience strengthening projects. As a result, the number of projects that adopted our method remained steady. These included works on levees, revetments and quay walls of rivers, coasts and harbors, and road-related bridges and retaining wall constructions. However, customers' appetite for capital spending remained cautious, affected by rising construction costs and the resulting decline in construction volume as well as shortage of skilled workers.

      In domestic product sales, we made progress on sales of SILENT PILER F112 and F302 equipped with a flywheel-type pile auger as standard, backed by the solid demand for machinery for hard ground.

      In overseas operations, we have been working to establish GTOSS*2,(GIKEN Total Support System), a comprehensive support service for customers, accelerating the market expansion in cooperation with the member companies. At the same time, we have been driving market creation, working with partner companies that can collaborate with us locally, as well as tapping new customers who share the value of press-in method.

      In Asia, we delivered three machines including large-scale specialized machinery to the customer whom we acquired during the previous fiscal year in Singapore. This capital investment is on the back of brisk demand from businesses such as airport maintenance projects. The customer, who completed a training program at Press-in Dojo, a training facility we opened in the previous fiscal year, is now chalking up a track record of construction with a high operating rate.

      In Europe, we won new customers in the U.K. and delivered them large-scale specialized machinery. The machinery is in operation for a high-speed railway project, and the demand is expected to continue. The Gyropress Method was adopted for the first time in Germany for bridge pier installation work, and it was completed using rental equipment with operators. We will drive market creation for the Gyropress Method, receiving a tailwind from the completion of the construction.

      In North America, we delivered large-scale specialized machinery to a construction company in the northern east coast region, which we set as one of our target regions and acquired our first customer in the region. Regarding the customer as a starting point, we will accelerate widespread adoption of the method.

      Under such circumstances, for the three months under review, net sales were 7,562 million yen (an increase of 36.7% YoY), operating profit was 1,148 million yen (an increase of 78.0% YoY), ordinary profit was 1,255 million yen (an increase of 84.9% YoY), and profit attributable to owners of parent was 978 million yen (an increase of 167.0% YoY).

      The performance by segment is as follows.

      1. Construction Machinery Segment

         As mentioned earlier, progress in product sales both in Japan and overseas resulted in higher revenue. Although selling, general and administrative expenses, including research and development expenses, increased, the operating profit also rose. Consequently, segment revenue amounted to 5,606 million yen (an increase of 50.0% YoY) and operating profit reached 1,464 million yen (an increase of 68.2% YoY).

      2. Press-in Work Segment

         In Japan, our construction methods were steadily adopted. Revenue rose due to the steady progress of projects including ECO Cycle installation (Hyogo Prefecture), the reconstruction of roads affected by the 2024 Noto Peninsula Earthquake (Ishikawa Prefecture), earth retaining wall construction associated with road improvement construction (Hokkaido Prefecture), and waterproof wall construction for a power plant (Gifu Prefecture). However, profit declined due to a decrease in the number of high-value-added development projects. Overseas, rentals with operators grew steadily in Germany. As a result, segment revenue amounted to 1,955 million yen (an increase of 9.0% YoY) and operating profit was 199 million yen (a decrease of 34.6% YoY).

         *1. A construction method in which high-rigidity, high-quality piles (allowable structural members) are pressed deep into the ground to form "Implant Structure" that exhibits strong resistance to earthquakes, tsunamis, floods, and other external forces.

         *2. A comprehensive support service that helps improve on-site productivity by providing member customers with products and know-how, such as technological services.

   2. Explanation of Financial Position (Assets)

      Total assets as of November 30, 2025 decreased by 516 million yen from the end of the previous consolidated fiscal year to 47,320 million yen. This was the net result of a decrease of 790 million yen in current assets, including finished goods, and an increase of 273 million yen in non-current assets, including machinery, equipment, and vehicles.

      (Liabilities)

      Total liabilities as of November 30, 2025 increased by 42 million yen from the end of the previous consolidated fiscal year to 7,593 million yen. This was due to an increase of 228 million yen in current liabilities, including notes and accounts payable-trade, and a decrease of 186 million yen in non-current liabilities, including long-term borrowings.

      (Net assets)

      Net assets as of November 30, 2025 decreased by 558 million yen from the end of the previous consolidated fiscal year to 39,726 million yen. This was mainly due to a decrease in retained earnings.

   3. Explanation of Consolidated Earnings Forecasts and Other Forward-looking Statements There are no changes in the full-year earnings forecast announced on October 10, 2025.
