Notice of Revision of Earnings Forecast for the Second Quarter of the Fiscal Year Ending March 2027

Revision of earnings forecast and factors

This document compiles the revision of the earnings forecast for the cumulative second quarter of the fiscal year ending March 2027, as approved at the Board of Directors meeting held on September 25, 2026. Increases in new housing starts and progress in selling price revisions are expected to raise net sales above the previous forecast, chiefly in the core building materials and flooring substrates applications. Although energy costs and raw material prices rose due to geopolitical developments in the Middle East, and various expenses related to labor and inflation increased, these cost increases are expected to be offset by the effect of the price revisions, resulting in higher profits. The full-year forecast remains unchanged due to ongoing uncertainty.

Outlook and considerations

While the interim period profit outlook has been revised upward, the full-year outlook remains uncertain and depends on trends in raw material prices, energy costs, and logistics costs. Exchange rates, market trends, and material cost trajectories could affect future performance, so further outlook revisions may be disclosed.
