   1. Overview of Results of Operations for the Fiscal Year under Review (January 1, 2025 to December 31, 2025)

      During the consolidated fiscal year under review, the Japanese economy was on a gradual recovery path due to improved employment and income conditions resulting from wage hikes and the effects of various policies. This offset downward pressure on the economy associated with sluggish personal consumption caused by rising prices and increased risks of an economic downturn caused by trends in U.S. trade policies.

      In the Japanese construction industry, where the Okabe Group's core customers operate, public investment was firm partly due to the effects of the supplementary budget, and the private investment was gradually recovering. However, the environment remained challenging chiefly due to delays in the commencement of construction caused by a chronic shortage of construction workers and continued high steel material prices.

      In this business environment, under OX-2026 (Okabe Transformation 2026), the medium-term management plan, the Group set customer-centric initiatives (prioritizing the development of a system to solve customers' problems and the implementation of initiatives to solve them), implementing human capital management and strengthening the foundation of management, and promoting digital transformation. With these three strategies as the cornerstones of our business strategy, we have been working toward the sustainable development of the company and the enhancement of its corporate value.

      Operating results by business category of the Group are as follows. [Construction-related products]

      Looking at domestic sales of construction-related products by product, sales of temporary building and formwork products were

      sluggish due to a decline in the floor area of reinforced concrete buildings and construction delays caused by a shortage of construction workers and soaring construction costs, despite efforts to expand sales of products related to the new formwork method with single pipe and rental services, and various campaigns to increase sales volume. As a result, sales decreased 8.7% year on year.

      Civil engineering products and materials increased 7.2% from the previous consolidated fiscal year as a result of efforts to capture demand for landslide prevention products against the backdrop of the government's land resiliency policy and the contribution of orders received for disaster restoration support projects.

      Net sales of structural products and materials increased 1.6% from the previous year, despite a decrease in the floor area of steel-framed buildings, thanks to the start of sales of improved versions of column base product (Select Base) for steel-framed buildings, the capture of demand for large properties, and the strengthening of sales for small and medium-sized properties.

      Overseas sales of construction-related products increased 12.2% from the previous consolidated fiscal year as a result of strong sales of main products in the U.S. due to the completion of a new warehouse and the strengthening of an immediate delivery system, in addition to tapping into infrastructure-related construction demand.

      As a result, sales in the construction-related products segment increased 2.6% year on year, to 63,079 million yen, and operating profit rose 8.7% year on year, to 3,747 million yen.

      [Other businesses]

      Net sales of industrial machinery products increased year on year as a result of efforts to expand sales of high value-added products such as custom-made products that meet customer needs.

      In marine material products, sales of large floating fish reef products remained strong through the first half of the fiscal year, but sales slowed somewhat toward the end of the fiscal year compared to last year, when large projects were in progress. Consequently, net sales decreased from the previous year.

      Sales of automotive products increased compared with the previous year, despite the truck/trailer market facing uncertain prospects, due to price responses based on the impact of tariffs and stepped up sales efforts to major customers.

      Accordingly, sales in the other segment increased 5.7% year on year, to 6,679 million yen, and operating profit rose 36.0% year on year, to 1,015 million yen.

      As a result, consolidated net sales for the fiscal year under review increased 2.9% year on year, to 69,758 million yen, and consolidated operating profit grew 13.5% year on year, to 4,762 million yen. Consolidated ordinary profit rose 14.9% year on year, to 5,081 million yen, and profit attributable to owners of parent was 3,285 million yen (loss attributable to owners of parent of 874 million yen in the previous year).

      (Note) Other businesses is a business that does not belong to our core business of construction-related products, and is engaged in manufacturing and sales of industrial machinery products, manufacturing and sales of marine material products, sales of bolts and nuts for automobiles.

      PT. Okabe Hardware Indonesia was engaged in tenant leasing business, but has decided to discontinue the tenant leasing business and is proceeding with the liquidation of this business following the closure of the store on December 21, 2025.

   2. Overview of Financial Position for the Fiscal Year under Review [Assets]

Current assets at the end of the fiscal year under review amounted to 46,777 million yen, a decrease of 2,047 million yen from the previous fiscal year-end, due mainly to a decrease in cash and deposits.

Non-current assets increased 89 million yen from the previous fiscal year-end, to 38,238 million yen, primarily owing to an increase in investment securities.

As a result, total assets decreased 1,962 million yen from the previous fiscal year-end, to 85,030 million yen.

[Liabilities]

Current liabilities decreased by 3,581 million yen from the previous fiscal year-end, to 14,747 million yen due to a decrease in other (accounts payable - other).

Non-current liabilities decreased by 746 million yen from the previous fiscal year-end, to 8,376 million yen, largely due to a decrease in retirement benefit liability.

As a result, total liabilities decreased 4,328 million yen from the previous fiscal year-end, to 23,124 million yen.

[Net assets]

Net assets increased 2,365 million yen from the previous fiscal year-end, to 61,906 million yen. The shareholders' equity ratio was 72.8%, up 4.4 percentage points from the end of the previous fiscal year.
